Method and device for punching to manufacture two-dimensional pattern

Abstract

The invention relates to a method and device for punching to manufacture a two-dimensional pattern. The method comprises the steps that a punch pin moving mechanism drives a punch pin die to move transversely for X displacement so as to change the transverse relative position of the punch pin die and a leather material; a leather material moving mechanism drives the leather material to be punchedto move longitudinally for Y displacement so as to change the longitudinal relative position of the punch pin die and the leather material; and a punch pin lifting mechanism drives the punch pin die to rise and fall, and then the leather material is punched by the punch pin die. The two-dimensional coordinate position of the punch pin die relative to the leather material can be changed by changingvalues of the X displacement and the Y displacement, therefore, a plurality of different types of patterns can be manufactured through punching by just one set of die without exchanging the punch pindie frequently, the specifications and the number of dies are greatly reduced, and die change work intensity of workers is greatly reduced; and moreover, since the punch pie die can be moved transversely for the X displacement, the number of the punch pins of the die can be greatly reduced so that the pressure required for punching the leather material can be reduced, the rigid of machines does not need to be too high, and the manufacturing cost is beneficially reduced.

Description

technical field [0001] The invention relates to the field of leather punching machines, in particular to a two-dimensional pattern punching manufacturing method and a device thereof. Background technique [0002] Leather punching machine refers to an automatic equipment for punching leather, which is suitable for leather, cowhide, artificial leather, plastic, PU, ​​EVX, PVC, various cloth, paper, leather accessories, shoes It is widely used in the industries of car breathable cushions, luggage, handbags, stationery, shoes, breathable materials, advertising paper products, etc. Now the punching needle mold of the leather punching machine on the market cannot be moved, and a pair of molds can only punch out one pattern.

Problems solved by technology

Now the punching needle dies of leather punching machines on the market cannot be moved, and a pair of dies can only punch out one pattern. The disadvantages of this traditional punching method for leather punching machines are: (1) only one part of the leather is punched. Dimensional movement, when punching leather with different patterns, it is necessary to replace the molds with different patterns for punching, resulting in a large number of corresponding molds, high manufacturing costs and troublesome maintenance of multiple molds, and flexible processing of patterns cannot be realized; (2) Due to the One drop punches out the pattern, the number of punching pins on the mold is too many, tens of thousands of them are completely covered with the mold plate, which leads to a very long time for mold manufacturing and high manufacturing cost, and too many punching pins require a large drive Power is used to drive the punching, and the rigidity of the machine is required to prevent punching deformation, and if only one punching needle has a problem in the later stage, it is very difficult to find the problematic punching needle
