Punching machine suitable for cloth, leather and artificial leather

Abstract

The invention provides a punching machine which is uniform in impact and excellent in punching precision and punching effect, and suitable for cloth, leather and artificial leather, and is especially capable of improving the punching precision and the punching effect aiming at multiple holes. The punching machine provided by the invention comprises a rack, wherein a punching cutter, a punching plate and a drive mechanism are arranged in the rack; the punching plate is movably arranged in the rack up and down and impacts the punching cutter; the punching plate is driven to move up and down by the drive mechanism; the tail end of the punching cutter is in a plane shape of which the area is equal to the area of a punching hole to be processed; the punching plate comprises a surface in a plane shape; the surface of the punching plate is parallel to the plane of the tail end of the punching cutter; the surface area of the punching plate is larger than the area of the plane formed at the tail end of the punching cutter; the rack comprises an elastic component acting on the punching cutter; and the punching cutter comprises a static station under the action of the elastic component only, and comprises an up and down microstroke under the combined action of the punching plate and the elastic component.

Description

technical field [0001] 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 [0002] 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 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...

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
