Punching machine

Abstract

The invention provides a punch, at least comprising one machine bench, an upper shoe on the machine bench, a lower shoe on the machine bench, a driving unit for driving the upper shoe, a linear slideway group with at least one vertical furnishings. The upper shoe is subjected to linear guide by linear slideway group to make the operation course of upper shoe more stably quickly and accurately. The setup amount of the linear slideway group can fluctuate as use require and can be set on the rear side or left side or right side, or the linear slideway group can be actualized using setting manner of multi-group and multi-side.

Description

technical field [0001] The invention relates to a structural technology of a processing machine tool, especially a structural technology of a punching machine. Background technique [0002] Generally speaking, the structure of a punch press mainly includes a machine, an upper die set on the machine, a lower die set on the machine, and a drive unit to drive the upper die. . . . [0003] Among them, the upper die base is a vertical reciprocal displacement mechanism used to lift and lower the lower die base in the stamping stroke, so it is necessary to set a limit slider on the machine table relative to the upper die base on both sides of the upper die base. , and the two sides of the upper die base are clamped so that the upper die base is worn between the limit sliders, so that the upper die base can be rubbed against by the limit sliders on both sides during the lifting and stamping stroke And guide to the correct punching direction. [0004] But the guide technology of th...

AI Technical Summary

Problems solved by technology

[0005] 1. The limit slider is used to clamp both sides of the upper mold base, so its volume is relatively large, and it also needs to use more metal materials for forging or casting

[0006] 2. The guiding accuracy of the limit slider to the upper mold base is not only affected by the processing precision of the limit slider and the upper mold base itself, but also affected by the assembly accuracy therebetween. Therefore, the guiding accuracy is often difficult to control, and even the problem of insufficient guiding accuracy and waste of stamping materials often occurs

[0007] 3. There is normal high-speed reciprocating fri
