Description

Technical Field

[0002] In the hardware manufacturing process, hydraulic presses are often used for the processing of various hardware stamping parts. The punching principle is based on the Pascal principle, and the pressure is transmitted through the hydraulic system to drive the punch processing.

[0003] At present, hydraulic presses generally include three major components: a machine body, a power system, and a hydraulic control system. Among them, the main parts of the machine body used for punching include a punch and a fixture for clamping the workpiece to be processed. The machine body also includes a workbench for the fixture to be installed. In addition, the fixture generally uses fixing bolts and fixed clamps to clamp the workpiece to be processed. There are multiple fixed clamps and they are arranged at intervals along the circumferential direction of the processing position of the workpiece to be processed. When installing the fixed clamps, the fixing bolts are passed through the fixed clamps and then threaded to the workbench, and the fixed clamps are in a pre-tightened state before use. During processing, the workpiece to be processed is placed on the workbench, and the workpiece to be processed is located between the fixed clamps and the workbench; then the fixing bolts are rotated so that the bottom of the fixed clamps is pressed against the top of the workpiece to be processed, and the workpiece to be processed is locked, and the punch can be used to punch the workpiece to be processed.

[0004] During the processing, each time the workpiece is processed, it is necessary to manually tighten multiple fixing bolts using a wrench to lock the workpiece using a fixed clamp. Although this locking method can meet the clamping requirements of the workpiece, the work efficiency is very low and it is not suitable for large-scale processing. Utility Model Content
