Punching machine suitable for cloth, hide and leather

Abstract

The invention provides a punching machine suitable for cloth, hide and leather. The punching machine is uniform in impact, high in punching accuracy, excellent in punching effect and particularly capable of improving the punching accuracy and the punching effect of multiple holes. The punching machine suitable for cloth, hide and leather comprises a rack, a punching knife, a punching plate and a driving mechanism are arranged in the rack, the punching plate is installed in the rack in a vertically movable mode and has an impact effect on the punching knife, and the driving mechanism drives the punching plate to move vertically; the tail end of the punching knife is provided with a plane with the area equal to that of pre-machined punching holes, the punching plate is provided with a planar surface, the surface of the punching plate is parallel to the plane at the tail end of the punching knife, and the area of the surface of the punching plate is larger than the area of the plane formed at the tail end of the punching knife. The rack is provided with an elastic component acting on the punching knife, and the punching knife has a static station under the single action of the elastic component and a vertical microstroke under the combined action of the punching plate and the elastic component.

Description

[0001] This application is a divisional application for Chinese invention patent application number: 201310096721.2, application date: March 25, 2013, name: a punching machine suitable for cloth, leather and leather. technical field [0002] The invention relates to a punching machine, in particular to a semi-automatic punching machine suitable for punching holes in cloth, leather and leather. Background technique [0003] Existing perforated part, many finishes by manual drilling. Not only is the efficiency low, but also the punching accuracy is low, which affects the quality of the final product. The prior art discloses a punching machine suitable for cloth, leather and leather. There are punching knife, punching plate and driving mechanism in the frame. The punching plate can be installed in the frame up and down and impact on the punching knife. The driving mechanism drives the punching plate to move up and down. The end of the punching knife is a plane, and the punching...

Problems solved by technology

Not only is the efficiency low, but also the punching accuracy is low, which affects the quality of the final product. The prior art discloses a punching machine suitable for cloth, leather and leather. There are punching knife, punching plate and driving mechanism in the frame. The punching plate can be installed in the frame up and down and impact on the punching knife. The driving mechanism drives the punching plate to move up and down. The end of the punching knife is a plane, and the punching plate It has a flat surface, the surface of the punching plate is parallel to the plane of the end of the punching knife, and the surface area of ​​the punching plate is larger than the plane area formed by the end of the punching knife. The defect of the punching machine with this structure is that the punching accuracy is still insufficient. The punching knife belongs to the interaction between hard objects. There is inevitably a flatness error between the end plane of the punching knife and the surface of the punching plate. Then the material on the hole may not be punched successfully due to the uneven impact force between the two. Therefore, one of the feasible ways to improve the punching accuracy is to improve the flatness of the end plane of the punching knife and the surface of the punching plate, but the processing is extremely difficult, and it is impossible to eliminate the uneven punching under the premise of controlling a certain cost, especially The above disadvantages will be more obvious when multiple punching knives are required to punch multiple holes
