Abstract

A processing technology that can ensure the flatness of a thin plate after punching a salad hole, including: 1. Stress release holes are punched at the processing position corresponding to the salad holes; the drawing holes are at least located on the side of the long hole away from the edge of the plate; It is located in the processing position of the long hole and is arranged in a straight line along its length direction; 2. The first punching is performed on the salad hole; 3. The long hole is punched, and the long hole is connected with each Keep a distance between the salad holes; 4. Carry out the second punching of the salad holes; 5. Press the marking lines at the two ends corresponding to the length direction of the long holes, and the marking lines extend along the width direction of the long holes, and are located in the long The side of the strip hole away from the edge of the sheet. The invention can eliminate the punching of salad holes and long strip holes in thin plates, especially the S-shaped deformation of the long side of the product caused by the stress concentration after punching the salad holes. Therefore, it has high industrial value.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a processing technology for ensuring the flatness of thin plate materials after punching salad holes. Background technique [0002] At present, in plate processing, it is usually difficult to process thin plates. Due to its thin thickness, how to ensure the flatness is a difficult point in the process when punching salad holes and punching long holes. [0003] Such as figure 1 As shown, it is a thin plate product, and its requirements are: there are two long holes near the edge of the product, and there are 8PCS CSK holes (salad holes) on the small surface. The traditional processing technology for this product is: front punching, punching, reverse punching and punching elongated holes. Since there are two long holes on one edge of the thin plate product, and each salad hole is close to the edge, a large amount of stress will accumulate in the plate after punchi...
