Thick plate forming drawing die

Abstract

The invention discloses a thick plate forming drawing die. The thick plate forming drawing die comprises an upper die base, a lower die base and a material pressing ring, wherein a female die is arranged on the upper die base, a male die corresponding to the female die is arranged on the lower die base, the material pressing ring floats between the upper die base and the lower die base under the action of a nitrogen spring, a through hole allowing the male die to freely penetrate is formed in the material pressing ring, a first limiting block is arranged on the lower surface of the upper die base, a pressure adjusting block corresponding to the first limiting block is arranged on the upper surface of the material pressing ring, the pressure adjusting block is adjustable in height and is used for controlling the distance between the material pressing ring and the female die so as to adjust the clamping force on plates, a second limiting block acting on the lower surface of the materialpressing ring is arranged on the lower die base, and the second limiting block and the pressure adjusting block are located on the same straight line. The thick plate forming drawing die is high in adjustability, in the thick plate stretching process, the portions, prone to wrinkling or cracking, of the plates are analyzed, the pressure on the plates is adjusted through the pressure adjusting mechanism, wrinkling and cracking phenomena are effectively controlled, and finished products are high in consistency and quality.

Description

technical field [0001] The invention relates to the technical field of thick plate forming, in particular to a thick plate forming drawing die. Background technique [0002] Such as figure 2 As shown, the thick plate is processed into the product shown in the figure, and it is generally formed by drawing process. Since the forming shape is not necessarily regular, the drawing force at each point is not balanced, and the thickness of the plate is large, which increases the difficulty of forming and is prone to local defects. Drawing wrinkling or cracking phenomenon, resulting in defective products. In addition, this type of traditional clam shell thick plate drawing die lacks adjustment devices, and the adaptability is insufficient, and the product consistency is poor. It needs to be adjusted continuously in the later stage, which affects the overall progress of the product, and the appearance of the product has flaws. Therefore, the cost is high, the processing efficiency ...

Problems solved by technology

[0002] like figure 2 As shown, the thick plate is processed into the product shown in the figure, and it is generally formed by drawing process. Since the forming shape is not necessarily regular, the drawing force at each point is not balanced, and the thickness of the plate is large, which increases the difficulty of forming and is prone to local defects. Wrinkling or cracking during drawing, resulting in defective products

In addition, this type of traditional clamshell thick plate drawing die lacks adjustment devices, and the adaptability is insufficient. The product consistency is poor, and it needs to be adjusted continuously in the later stage, which affects the overall progress of the product, and the appearance of the product is flawed.

Therefore, the cost is high, the processing efficiency is low, and the quality of the finished product is low, which needs further improvement
