As we all know, the final bending accuracy of the bending machine depends on whether there is the best: bending equipment, bending mold system, bending material, and operator proficiency. The bending machine mold system includes bending molds, mold clamping systems and compensation systems. There is no doubt that the bending machine mold and compensation system are important to the bending accuracy. However, we know relatively little about the bending machine clamp. Today we will give a brief introduction to the bending machine clamp.
Classification by clamping method:
1. Manual clamping clamp: It is an economical clamp suitable for bending machines that do not frequently change molds. Operators are required to manually lock each splint. For example, the manual clamping system with a clamping pin structure developed by WILA can provide a consistent clamping force throughout the entire working length, eliminating the need for debugging after each mold section is clamped. It has automatic seating and automatic calibration mechanisms, allowing the mold to be accurately centered and seated2.
2. Automatic clamp(Quick clamp): Based on the “single point operation” concept, only one button is needed to clamp and loosen the mold, which is suitable for bending machines with frequent and rapid mold changes. The power sources of automatic clamping systems include electricity, hydraulic and pneumatic2.
3. Hydraulic clamp: Equipped with a hydraulic oil pipe of the same length as the bending machine. After the pressure hydraulic oil is introduced, the oil pipe expands to push the hardened clamping pin to clamp the mold. The positioning reference plane is unified, the dimensional accuracy is high, the load-bearing capacity is large, and it can effectively compensate for the accumulated errors in machine processing.
4. Pneumatic clamp: Air pressure pushes the piston rod to move so that the clamping pin extends out of the clamping mold. In addition to the accuracy and durability of the hydraulic clamping system, it also has the advantages of clean, simple, convenient, fast and economical. It has a self-locking mechanism and can use conventional compressed air power in the workshop.
How to choose a suitable bending machine clamp requires comprehensive consideration of the workpiece material, production accuracy requirements, production batch size, and procurement cost to choose a bending machine clamp suitable for your production. If you have any questions about the selection of bending machine clamps, you can contact MACRO at any time, we always welcome your consultation.
