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. Additionally, in actual production, if oil resistance is required for the suction cups, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing. Typically, 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. Additionally, in actual production, if oil resistance is required for the suction cups, 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 collar. A flat vacuum suction cup is first connected via a fitting to vacuum equipment, such as a vacuum generator, and then brought into contact with the object to be lifted, such as glass or paper. The vacuum equipment is started to create negative pressure inside the suction cup, securely holding the object so that transport can begin. When the object reaches its destination, air is gently introduced into the vacuum suction cup, changing the internal pressure from negative to zero or slightly positive, allowing the suction cup to release the object and completing the lifting and handling task. 1) High wear. Since it is generally made of rubber and directly contacts objects, it experiences severe abrasion and wears out quickly. It is a pneumatic wearable part. This is precisely why it stands out prominently among many pneumatic components. 2) Easy to use. Regardless of the material of the object being sucked, it can be used as long as a seal can be formed without air leakage. Electromagnetic suction cups cannot do this; they can only be used on steel materials and cannot lift plates or objects made of other materials. 3) No pollution. Vacuum suction cups are particularly environmentally friendly, do not pollute the environment, and produce no light, heat, or electromagnetic effects. 4) Does not damage the workpiece. Because vacuum suction cups are made of rubber, picking up or placing down the workpiece causes no damage to it. Hook-type and steel cable lifting gear cannot achieve this. In some industries, where surface requirements for workpieces 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 fall off 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 a clamp. 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 without relying on the manipulator can be added to improve this situation.
