Description

technical field

[0001] The invention relates to the field of mechanical processing, and more specifically, to a workpiece notch stamping device. Background technique

[0002] Such as figure 1 As shown, many factories commonly use the workpiece 30 (such as angle steel, steel plate) to process gaps 33 or corners of different lengths and widths. (For example, go notch of angle steel, steel plate chamfering) common practice is to cut workpiece 30 with gas cutting torch first, and then the flash burr produced by workpiece 30 with gap 33 is polished. This manufacturing method is complex in process, low in efficiency, high in labor intensity, difficult to guarantee the size, and has problems such as poor cross-section quality of the product. Contents of the invention

[0003] The invention aims to provide a workpiece notch stamping device to solve the problems of complicated process and low efficiency when processing notches or corners of workpieces.

[0004] The invention pro...
