Clamptek Encyclopedia: Air Hydraulic Pump (AHP Series)

Product Features • It uses factory compressed air to generate hydraulic pressure as the power source for the hydraulic cylinders, and its flow rate is larger than a general hydraulic pump. The pressure can be continuously pumped, and there is no limit on the boosting stroke of the actuating cylinder. • Pressure adjustment is made by the pneumatic pressure regulating valve, and the pump is stopped when the hydraulic pressure is reached. If the hydraulic pressure drops, the pump will compensate automatically. This series is explicitly suitable for hydraulic fixtures with the smaller flow or other long-term hydraulic clamping mechanisms. It also features energy savings, no oil temperature growth, and economical advantages.   Product Main Overview • The imported high-performance pneumatic selector valve is used to ensure longer life expectancy and stable operation of the air hydraulic pump. • It adopts Clamptek's customized special sealing components, and with the cooperation of the company's advanced technology on pneumatic/hydraulic cylinders, it ensures the pneumatic cylinders to have a long-term and stable operation without any air leakage. • The high-pressure hydraulic port adopts NOK seals from Japan to ensure steady and reliable output pressure.   Product Advantages 1. Compact Structure for Space Saving The volume of a common 7MPa, 16L/min hydraulic pump unit oil tank is generally at 40 liters or 60 liters, and a few can achieve to have as small as 20 liters. However, the minimum tank volume of Clamptek’s air hydraulic pump unit is 5 liters.   2. Low Maintenance Fee Hydraulic oil generally needs to be replaced once a year. Compared with a common 40-liter pump unit, this Clamptek series can save up to 35 liters worth of hydraulic oil annually.   3.   Energy-Saving • For example, suppose during a product processing cycle, the cylinder clamping time is about 5 seconds, the processing time is about 60 seconds, and the material loading time is at 15 seconds. The machine works 16 hours a day. After deducting the material loading and processing time, the total air consumption of the air hydraulic pump takes 1 hour per day   [16 x 60 x 60/ (5S + 60S+ 15S)] x 5S = 3600S   Taking Clamptek’s AHP-16 air hydraulic pump as an example, the air consumption of continuous operation is about 3.36 cubic meters per hour (A 22kw air compressor generally has an exhaust volume of 3-3.5m³/min). One minute of use of the air compressor can generate a day worth of air consumption usage for the air hydraulic pump. Therefore, the air and electricity consumption of the air hydraulic pump is very minimal and cost-efficient. • For a common 7MPa, 16L/min hydraulic power unit, assuming that it is calculated by 1.5KW motor, works 16 hours a day and consumes 24 kWh of electricity per day. • Therefore, switching to an air hydraulic pump unit can save up to 23 kWh worth of electricity per machine per day.   4. Low-Temperature Growth • Without any leakage, the air hydraulic pump unit automatically keeps the pressure constant after the workpiece is clamped by the hydraulic cylinder, so the system has no temperature growth. And because of the low-temperature rise of the hydraulic system, the life expectancy of the cylinder seals is greatly improved, and the cycle of hydraulic oil replacement can also be extended.   5. Easy Connection to CNC Machines • High-pressure hydraulic oil can go to the machine tool fixture without any power connection to the machine tool. The pump unit adopts a selector valve with manual control or air-controlled hydraulic selector valve.   6. Lower Noise Level Compared to Other Similar Products • The working noise of Clamptek’s AHP series is at 75 decibels only, compared with similar products of other mainstream Japanese brands which are at 78 to 85 decibels.   • Note: Compared with the common electric hydraulic pump, the output flow of the hydraulic pump is smaller. Product Application 1. The air hydraulic pump is suitable for vertical and horizontal processing fixtures. 2. Since it does not need to be connected to any electrical components, they are applicable to a working environment with explosion-proof requirements. Recommendation!! Clamptek's Air Hydraulic Pump – AHP Series:   Maximum operating pressure: 6 kgf/cm²   -Type A: It is installed with an ISO specification manifold and solenoid valve and is suitable for single-acting or double-acting hydraulic cylinders. The electromagnetic ball valve has been equipped to improve the internal leakage and life expectancy of the air hydraulic pump.   - Type B: It includes PT threaded manifold block and can be connected to a hydraulic manual controlling valve for operation.

Clamptek Encyclopedia: Pneumatic Support Clamp (CSW Series)

In order to meet the needs of customers, Clamptek has developed and produced pneumatic support cylinders in addition to the hydraulic support cylinders we previously introduced. Therefore, we will be presenting the pneumatic support cylinders in this article. pneumatic clamp is a pneumatic clamping device that uses air pressure to generate the clamping force. It is often used in light metal-cutting and is mainly used in automated production lines and automated equipment such as pneumatic fixtures and jigs. Pneumatic Support Clamp: It is a supporting workpiece that can be elastically adjusted to the desired height. During processing, the air pressure causes the piston rod to move in the direction of the pressure. When the piston rod reaches the supporting position, it will stop and maintain stable support at that position. The support clamp can effectively prevent the vibration generated during the processing of the workpiece and the deformation during clamping. The support cylinder can improve the processing accuracy of the workpiece, and because of its small size, it can be configured and used in a narrow space. Which types of workpiece require the help of a support clamp during machining? Thin machining parts Irregularly shaped workpieces Workpieces without supporting structure Workpieces that need to be machined on a flat surface Workpieces with uneven bottom height The Features of Clamptek's Pneumatic Support Clamp: It can improve the working environment and meet the needs of a clean working environment. It's suitable for light metal cutting and when workpieces require fine precision processing, e.g. mobile phones. The cylinder itself is lightweight and compact, which is suitable to use when there are limited spaces during processing. Recommend!! Clamptek's Self-Produced Pneumatic Support Clamps – CSW series: - CSW's maximum working pressure is at 1 MPa and minimum working pressure is at 0.4 MPa. - The outer diameter of CSW cylinder has four sizes: M26x1.5, M30x1.5, M36x1.5, M45x1.5 (mm) (M30x1.5 is the best-selling CSW product of Clamptek) - CSW has two types: spring rising type (A), Pneumatic Rising Type: (standard) (B). * Spring-up type (A): The initial state of the piston rod is up, and the workpiece is placed on the piston rod and dropped to a certain distance due to the weight of the workpiece. At this time, the clamping force of the supplied air pressure on the clamp cover is applied to the piston rod, so that the piston rod can support the workpiece firmly. * Pneumatic rising type (B): The initial state of the piston rod is down. When the air pressure is supplied, the piston rod rises and stops at any position of the workpiece. While stopping, the clamping force of the air pressure on the clamp cover is applied to the piston rod, so that the piston rod can stably support the workpiece. *If you need to order stronger springs, please contact the sales representatives for more information. *Notes: When installing, the bottom surface of the support clamp must be kept in close contact with the bottom surface of the mounting hole.

Clamptek Encyclopedia: Pneumatic Leverage Clamp (CALC series)

We mentioned in the first article (Clamptek Fixture Components 101) that the pneumatic cylinder is a pneumatic clamping device that uses air pressure to generate a clamping force to secure the workpiece. It is often used in light metal-cutting and is mainly used in automated production lines and automated equipment such as pneumatic fixtures and jigs. How to Choose the Types of Clamptek Pneumatic Clamps? Pneumatic cylinders are divided into support clamps, leverage clamps, swing clamps, push-pull clamps, etc. due to different operating methods. The selection of types is mainly based on the following to determine the type of pneumatic clamp to be used: the size of the fixture designed by the customer, the position that can be placed in space, and the type and shape of the workpiece. Introduction of Pneumatic Leverage Clamp: Pneumatic leverage clamps use air pressure to push the piston rod from top to bottom to generate clamping force in to secure or loosen the workpiece. In the process of manufacturing and processing, the leverage clamp can be used when the workpiece must be clamped from top to bottom instead of rotating and pressing or when it is necessary to bypass a raised obstacle. The Movement of Pneumatic Leverage Clamps: Pneumatic leverage clamps utilize the theory of clamping mechanism with lever principle to generate clamping forces through the linear reciprocating motion of the piston rod. When actuated, the gas will enter the clamp and the compressed air will exert pressure on the piston rod causing it to move. Then the force will drive the clamping arm through the fulcrum to clamp down and secure the workpiece to the desired location. Pneumatic leverage clamps can also use magnetic switches or other related controlling devices to achieve automatic controls. The Features of Clamptek’s Pneumatic Leverage Clamp: The clamp itself is lightweight. It fulfills the need for a clean working environment. In the case of the same bore size, the clamping force of a leverage clamp is greater than a swing clamp. It’s suitable to use when there are limited spaces during processing, e.g. inside the CNC milling machine. It’s suitable for light metal cutting and when workpieces require fine precision processing, e.g. mobile phones. Recommend!! Clamptek's Self-Produced Pneumatic Leverage Clamps – CALC series: ➤ The accessories required by the clamp have already been installed on the clamp, which is convenient for customers to use directly. ➤ The material of the clamp is made of aluminum alloy and carbon steel. It is wear-resistance, and has a longer life cycle and stronger durability. ➤ This series of pneumatic leverage clamp is interchangeable with products of similar specifications currently on the market.

Clamptek Fixture Components 101

What is a fixture? A fixture is a piece of equipment that holds workpieces quickly and safely in position during welding, assembly, etc. Fixture tables’ sizes, types, wiring layouts, component selections, and placements will be customized due to the different types of workpieces to be processed. Therefore, each fixture table is customized according to needs. Fixture components are auxiliary tools installed on the fixture table that act as helpers between the fixed workpiece and the fixture table. The fixture components are divided into various power sources, such as manual clamping devices, hydraulic clamping devices, pneumatic clamping devices, etc. We will next be introducing the three main clamping devices that are manufactured and sold by Clamptek: 1. Manual toggle clamps: a manual clamping device that is used in welding, drilling, and assembly fixtures. It is mainly used in non-automated equipment, such as inspection fixtures, welding fixtures, etc. Before automated fixtures, some manufacturers will use manual toggle clamps to increase the speed of operation. Features: Simple structure, convenient operation, fast loading and unloading. 2. Hydraulic clamps: a hydraulic clamping device that converts hydraulic pressure into clamping force to secure workpieces. It is often used in heavy metal-cutting and is mainly used in automated equipment. Features: 1). The hydraulic clamping force is larger than the pneumatic clamping force. 2). The hydraulic pressure is more stable than the air pressure, and there is less vibration when in use (because the hydraulic oil can hardly be compressed). 3. Pneumatic clamps: a pneumatic clamping device that uses air pressure to generate clamping force to secure the workpiece. It is often used in light metal-cutting and is mainly used in automated equipment. The entire set of equipment is systemized through air piping. Features: 1). In terms of housekeeping, pneumatic systems are easier to maintain in comparison to hydraulic counterparts due to oil leakage. 2). It is easier to control than hydraulic cylinders. 3). Air can be compressed, so when it’s impacted, it can buffer. 4). Pneumatic equipment is less complex than hydraulic equipment, and pneumatic power sources, such as air and other sorts of suitable pure gas are easier to obtain.                               Toggle Clamps                                      Hydraulic Clamps/Pneumatic Clamps *Our company mainly sells manual toggle clamps, hydraulic clamps and pneumatic clamps.
