Description

Technical Field

[0001] The present application relates to the field of sheet metal processing, and in particular to a flattening device for sheet metal cutting. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as automobile bodies), etc. Its most notable feature is that the thickness of the same part is consistent. The products processed by sheet metal processing are called sheet metal parts.

[0003] In order to prevent the sheet metal from warping during the cutting process and affecting the cutting quality, it is usually necessary to flatten and fix the sheet metal during cutting. However, when it is necessary to cut sheet metal parts of different sizes and thicknesses or to make precise cuts at any position on the sheet metal, the existing technology has obvious shortcomings. It is difficult to adjust the flattening device to flatten and fix both sides of any cutting position of the sheet metal, which makes it easy for the sheet metal to warp during the cutting process, affecting the cutting quality. In addition, the adaptability to sheet metal parts of different sizes and thicknesses is low, which reduces the practicality of the device and increases the production cost.

[0004] In view of the above-mentioned related technologies, the inventor believes that the flattening device for sheet metal cutting has the defect of being inconvenient to stably cut sheet metals of different sizes and thicknesses at any position;

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application.

A frame-shaped moving frame 4 is slidably connected to the opposite side surfaces of the first support plate 2 and the second support plate 3, so that the moving frame 4 drives a plurality of flattening plates 5 to move up and down, thereby being suitable for flattening sheet metal parts of different thicknesses. A plurality of plate-shaped flattening plates 5 are snap-connected to the inner side wall of the moving frame 4, so that the plurality of flattening plates 5 can be moved to flatten sheet metal parts of different thicknesses. The two pressing plates 5 are located on both sides of the sheet metal to be cut, so that the other two pressing plates 5 are located on both sides of the sheet metal, thereby stably pressing the sheet metal to prevent the sheet metal from warping during cutting and affecting the cutting quality. Rubber strips 17 are fixedly connected to the lower surfaces of several pressing plates 5 to increase the friction force when the pressing plates 5 flatten the sheet metal, prevent the sheet metal from sliding, and increase the stability of the sheet metal. Secondly, several groove-shaped blanking chutes 6 are opened on the upper surface of the base 1, and a box-shaped debris box 7 is slidably connected to the side surface of the base 1 so that the debris generated during cutting can fall into the debris box 7 through the blanking chute 6 for subsequent centralized processing.
