German Altratec workpiece fixtures Altratec model Altratec price

Altratec workpiece fixtures are one of the actuators for vacuum equipment. Generally, using vacuum suction cups to grip products is the most economical method. Vacuum suction cups come in various types; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for gripping products with rough surfaces, and polyurethane suction cups are highly durable. In addition, in actual production, if oil resistance is required for the suction cup, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing. Usually, to avoid scratching the surface of the product, it is best to choose suction cups with bellows made of nitrile rubber or silicone rubber. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices.

Altratec Workpiece Fixture Introduction

Vacuum suction cups are one of the actuators for vacuum equipment. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices, such as in construction, paper industry, printing, glass, and other industries, to perform tasks of holding and transporting thin and light items like glass and paper. Vacuum suction cups are also known as vacuum lifters and vacuum nozzles. Generally, using vacuum suction cups to grip products is the most economical method. Vacuum suction cups come in various types; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for gripping products with rough surfaces, and polyurethane suction cups are highly durable. In addition, in actual production, if oil resistance is required for the suction cup, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing.

Altratec Workpiece Fixture Principles and Features

The structure of a flat vacuum suction cup consists of the suction cup and the suction cup clamp. The flat vacuum suction cup first connects the vacuum suction cup to vacuum equipment, such as a vacuum generator, via a pipe, then contacts the object to be lifted, such as glass or paper. Starting the vacuum equipment creates negative pressure inside the suction cup, securely holding the object to be lifted, allowing transportation to begin. When the object is transported to the destination, air is smoothly injected into the vacuum suction cup, changing the internal pressure from negative to zero or slightly positive, causing the suction cup to release the object, thus completing the task of lifting and transporting heavy objects. 1) High wear. Since it is generally made of rubber and directly contacts objects, it suffers severe wear and tear, leading to rapid degradation. It is a pneumatic wearable part. Precisely because of this, it stands out significantly among many pneumatic components. 2) Easy to use. Regardless of the material of the object being sucked, as long as it can be sealed without air leakage, it can be used. Electromagnetic chucks cannot do this; they can only be used on steel, and cannot suck plates or objects made of other materials. 3) No pollution. Vacuum suction cups are particularly environmentally friendly, do not pollute the environment, and do not produce light, heat, or electromagnetic fields. 4) Does not damage workpieces. Since vacuum suction cups are made of rubber material, picking up or placing down workpieces will not cause any damage to them. Hook-type lifting gear and cable-type lifting gear cannot achieve this. In some industries, where requirements for workpiece surfaces are particularly strict, only vacuum suction cups can be used.

Altratec Workpiece Fixture Maintenance

When using vacuum suction cups (without clamps), note that the manipulator's movement speed should not be too high; otherwise, shear forces will be generated on the suction cup, causing the product to easily drop during rapid twisting. In some cases, a clamp can be used to ensure safe transport of the product. Considering the possibility of the product sticking to the mold, an air clamp can usually be installed to solve this problem. When the product's surface area is too small or the product is too heavy to use a vacuum suction cup, this problem can also be solved by using clamps. If the product has strict appearance requirements, the clamped area must not be the outer surface. To solve this problem, a sensor circuit can be installed. After confirming that the clamp or suction cup has firmly gripped the product, the sensor sends a signal to the manipulator, enabling it to proceed to the next operation. In cases where the manipulator's motion capability is limited and manual twisting or prying is required to demold the product or move it out of the forming area, a special cylinder capable of independent movement, not relying on manipulator operation, can be added to improve this situation.
