German SMW-AUTOBLOK workholding fixtures SMW-AUTOBLOK model SMW-AUTOBLOK price

SMW-AUTOBLOK workholding fixtures are devices used on machine tools to clamp workpieces and guide cutting tools. They refer to fixtures specifically designed for a particular operation on a specific workpiece. Their characteristics include a compact structure, rapid, convenient, and labor-saving operation, ensuring high machining accuracy and production efficiency. However, the design and manufacturing cycle is long, and manufacturing costs are high. When the product changes, the fixture becomes obsolete and is scrapped because it can no longer be used. It is only suitable for production with fixed products and large batch sizes. It contacts the positioning datum of the workpiece to determine the correct position of the workpiece in the fixture, thereby ensuring the correct relative position of the workpiece with respect to the cutting tool and the machine tool's machining motion during processing. It typically consists of positioning elements, clamping devices, tool-setting and guiding elements or devices, etc.

SMW-AUTOBLOK workholding fixture applications

Whether it is a simple hydraulic fixture or a complex integrated production line, the design process for hydraulic fixtures is the same: formulation of the overall scheme, selection of hydraulic cylinder type and specifications, selection of control valves, design of mechanical parts, selection of pump station accessories, and system connection. Hydraulic fixtures provide powerful clamping and positioning forces for various machining processes. Yunpower cylinders are used for positioning and clamping in automated machining processes. Products such as self-centering vises and self-centering clamping elements provide good positioning; swing cylinders and lever cylinders provide clamping force on the product; support cylinders prevent deformation of the product during machining. From simple fixturing to robot-assisted machining centers, cylinders provide clamping and support forces to improve production efficiency.

SMW-AUTOBLOK workholding fixture principles and features

The structure of a flat vacuum suction cup consists of the suction cup and the suction cup holder. 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 transport to begin. When the object reaches its 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 lifting and transport task. 1) High wear. Since it is generally made of rubber and directly contacts objects, it suffers severe wear and deteriorates quickly. 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 plates or objects made of other materials cannot be attracted. 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 workpieces causes no damage to them. Hook-type and cable-type lifting gear cannot do this. In some industries, where surface requirements for workpieces are particularly strict, only vacuum suction cups can be used.

SMW-AUTOBLOK workholding fixture maintenance

When using vacuum suction cups (without grippers), note that the manipulator's movement speed must not be too high; otherwise, shear forces will be generated on the suction cup, causing the product to fall off easily during rapid twisting. In some cases, a gripper can be used to ensure safe transport of the product. Considering that the product may stick to the mold, an air gripper is usually 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 gripper. 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 gripper or suction cup has securely held the product, the sensor sends a signal to the manipulator 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 molding area, a special cylinder capable of independent movement, not relying on manipulator operation, can be added to improve this situation.
