Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to an elastic mounting structure for a lower cutter die of a punching machine. Background Art

[0002] The punching die of a punching machine is generally installed below the upper platen, that is, the die is above the material when punching. This method is not conducive to the diverse design of the punching die due to limited design space. Therefore, some people install the punching die on the lower die mounting seat, that is, the die is below the material when punching. This makes the die installation design more convenient. However, the existing lower die seat has no upper and lower buffering function (that is, the upper and lower positions cannot be flexibly adjusted). This will cause the die to be worn by impact after multiple upper platen presses. Utility Model Content

[0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is how to replace the protective knife die. The specific technical solution is as follows:
