Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing equipment, in particular to a sheet metal processing flattening device. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming, etc. Its most notable feature is that the thickness of the same part is consistent. Due to its small thickness, sheet metal parts may bend during transportation, storage and handling. Therefore, before forming them, the sheet metal parts need to be flattened in advance to ensure the subsequent processing accuracy and quality. This requires the use of a sheet metal flattening device, as shown below.

[0003] After searching, the patent with the authorization publication number of CN220387510U discloses a sheet metal flattening device for sheet metal processing, including a processing box, a fixed column is fixedly connected to the outer wall of the middle section of the rear end of the processing box, a cross plate is fixedly connected to the outer wall of the front end of the fixed column, and an electric slide rail is arranged on the outer wall of the lower end of the middle section of the cross plate. In the utility model, through the linear guide rail and the sliding block, the sliding block drives the push plate to move, and the sponge at the lower end of the push plate is used to clean the sheet metal surface on the upper end of the plate, so that there will be no impurities on the sheet metal surface during flattening, and the sheet metal is cleaned during flattening. The electric slide rail and the first moving seat, the connecting plate at the lower end moves left and right, and the motor at the lower end of the connecting plate makes the screw rod move, driving the nut pair to rotate, and the fixed disk at the lower end of the nut pair rotates, and the second moving seat at the lower end of the fixed disk penetrates the guide columns at the front and rear ends, and the second moving seat moves up and down, and the flattening plate flattens each position of the sheet metal, thereby improving the processing efficiency of the sheet metal.

[0004] However, the above patent still has the following aspects that can be optimized:

[0005] When the sheet metal is flattened, since there are clamping and fixing structures around the sheet metal, the clamping and fixing structures will block and hinder multiple positions of the sheet metal when the sheet metal is clamped and fixed, making it impossible to flatten multiple positions around the sheet metal, and it is difficult to change this situation by adjusting the sheet metal. Subsequently, other tools or equipment are needed to perform secondary flattening on the multiple blocked positions around the sheet metal, resulting in the entire processing work being time-consuming, labor-intensive and inefficient. In addition, due to the obstruction of the placement plate, the clamping and fixing structure cannot be applied to sheet metal parts of various sizes, resulting in a small scope of application of the device. Finally, since the distance between the sponge used to clean the sheet metal and the placement plate is fixed and cannot be adjusted, it cannot be applied to the cleaning of sheet metal parts of various thicknesses. Therefore, its overall structure needs to be improved and its practicality needs to be improved. Utility Model Content

[0006] The purpose of the utility model is to provide a sheet metal processing flattening device to solve the problem that when the sheet metal parts are flattened, since there are clamping and fixing structures around the sheet metal parts, when the sheet metal parts are clamped and fixed, the clamping and fixing structures will cause obstructions to multiple positions of the sheet metal parts, making it impossible for multiple positions around the sheet metal parts to be flattened, and it is difficult to change this situation by adjusting the sheet metal parts.
