Description

Technical Field

[0001] The present invention belongs to the technical field related to stamping processing, and more specifically relates to a high-efficiency intelligent control stamping process. Background Art

[0002] Stamping is a metal processing method that uses molds and stamping equipment to deform metal sheets. The stamping process can produce parts of various shapes and sizes. It is divided into hot stamping and cold stamping according to the stamping temperature. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a commonly used stamping method for thin plates.

[0003] The patent document with patent number CN116274670B discloses a stamping die and a stamping process for stamping metal parts, which belongs to the technical field of metal part stamping dies. In order to solve the problem that the existing metal die is not convenient for positioning the metal parts multiple times through the linkage of the guide structure during the stamping process of the metal parts, the existing metal die causes the outer edge of the metal part to rub against the extruded or embedded structure when the metal part is stamped, thereby causing damage; by placing the metal part at the preset stamping position of the lower die, embedded in the middle position of the positioning component, the upper die is pressed down by external force, and the lower pressing component will contact the metal part to position the metal part. As the upper die continues to descend, the position of the lower pressing component does not change, and at the same time, the pressure-bearing component performs secondary positioning on the metal part.

[0004] The traditional stamping process has certain shortcomings when performing metal processing operations. The traditional stamping process performs stamping operations through the cooperation between the upper and lower molds. When performing complex structure stamping processing operations, multiple molds need to cooperate with each other, which reduces its stamping efficiency; secondly, when performing continuous stamping operations, it is affected by the feeding angle of the metal material, which makes the punching structure of the metal material prone to tilt during the stamping and shaping operation, thereby reducing its stamping processing quality; at the same time, when performing various types of metal material stamping processing operations, metal materials of different specifications need to be sorted and stored, and the classification and storage operations cannot be completed simultaneously in the stamping discharging link, thereby reducing its use effect. Summary of the invention

[0006] The problem to be solved by the present invention is:

[0007] 1. The traditional stamping process performs stamping operations through the cooperation between the upper and lower dies. When performing stamping operations on complex structures, multiple dies need to be used in coordination with each other, which reduces the stamping efficiency;

[0008] 2. Secondly, during the continuous stamping operation, affected by the feeding angle of the metal material, the punching structure of the metal material is prone to tilt during the stamping and shaping operation, which reduces the stamping processing quality;

[0009] 3. When performing stamping operations on various types of metal materials at the same time, metal materials of different specifications need to be sorted and stored, and the classification and storage operations cannot be completed simultaneously in the stamping and discharging link, which reduces its use effect.

[0010] The purpose of the present invention can be achieved through the following technical solutions:

[0011] A highly efficient intelligent control stamping process comprises the following steps:

[0012] Step 1: Place the metal material in a feed frame of a stamping device, clamp and fix both sides of the metal material by moving the clamping strips, and use the feed frame to drive the metal material to move so that the metal material moves between the stamping part and the lower die;
