Description

Technical Field

[0001] This utility model relates to the technical field of shearing machines for sheet metal processing, and more particularly to a shearing machine for sheet metal processing. Background Technology

[0002] Sheet metal work, sometimes also called sheet metal fabrication, generally involves shaping thin metal sheets by hand or with molds to create the desired shape and size. Further welding or minimal machining can then be used to create more complex parts. Examples include household chimneys, sheet metal stoves, and car bodies. Sheet metal fabrication is a crucial skill for sheet metal technicians and a vital step in the forming of sheet metal products. It encompasses traditional methods and parameters such as cutting, blanking, and bending, as well as the structures and parameters of various cold stamping dies, the working principles and operation methods of various equipment, and new stamping technologies and processes. Sheet metal processing requires the use of shearing machines for cutting. For example, Chinese utility model patent CN212761391U discloses an easily adjustable sheet metal shearing machine, including a worktable and a fixed frame. The worktable is fixed to the middle of the side of the fixed frame. A baffle is provided on the inner side of the fixed frame corresponding to the rear side of the worktable. Two symmetrically arranged grooves are provided on the inner side of the fixed frame corresponding to the baffle, and slide rails are provided inside the grooves. A linear motor is slidably mounted on the side of the slide rails. A horizontal plate is provided at the bottom of the linear motor, and a servo motor is provided on the upper surface of the horizontal plate. A rotating disk fixedly connected to the baffle is mounted on the output shaft of the servo motor. This sheet metal shearing machine can position, press, and cut sheet metal, preventing the sheet metal from warping during the cutting process. The cut sheet metal can be conveyed during the pushing process, facilitating manual docking. It offers high operational safety, improves work efficiency, and prevents scratches and wear on the sheet metal. It is simple to operate and easy to use.

[0003] The above devices still have some problems in use. When the material to be cut is not flat, it will lead to uneven cuts and other problems, resulting in low quality of the cut material. In order to ensure the quality of the material cutting process, a separate flattening process needs to be added, which results in low shearing efficiency. Utility Model Content
