Problems solved by technology

[0003] The above-mentioned forming method uses secondary processing, which increases the processing cost. Partial imprinting in the middle of the drum will cause changes in the size of the workpiece after drawing, and the bottom is prone to indentations, making it difficult to guarantee the quality of the workpiece.

Abstract

The invention relates to a two-way blank pressing drawing and coining integration die. The two-way blank pressing drawing and coining integration die comprises an upper die and a lower die, wherein the two-way blank pressing drawing and coining integration die is characterized in that the upper die comprises an upper die plate, an upper die base plate is fixed on the upper die plate, an upper die material pressure plate is arranged on the lower surface of the upper die base plate, an upper die material pressure spring is arranged between the upper die material pressure plate and the upper die plate, a punch is arranged on the lower surface of the upper die plate, and the lower surface of the punch is a workpiece forming surface; the lower die comprises a lower die plate, a first lower die base plate and a second lower die base plate are fixed on the lower die plate, a concave die is arranged on the upper surface of the second lower die base plate, a lower die material pressure spring is arranged between the first lower die base plate and the concave die, the upper surface of the concave die is the workpiece forming surface, a lifting pin is arranged in the middle of the concave die, and a lifting spring is arranged between the lifting pin and the lower die plate. The two-way blank pressing drawing and coining integration die has the advantages of being capable of improving forming property of materials, achieving one-step forming workpieces and automatically taking off of the workpieces, and high in workpiece accuracy.

Description

technical field [0001] The invention relates to a deep-drawing and embossing mold, in particular to a two-way blank-holder integrated deep-drawing and embossing mold. Background technique [0002] For workpieces that require deep drawing and embossing, the sheet is generally drawn into a cylindrical shape (such as figure 1 shown), and then a partial imprint is made in the middle of the barrel (as in figure 2 As shown), the secondary forming is adopted, and the embossing process is completed by two sets of molds. [0003] The above-mentioned forming method uses secondary processing, which increases the processing cost. Partial imprinting in the middle of the drum will cause changes in the size of the workpiece after drawing, and indentations are prone to appear on the bottom, making it difficult to guarantee the quality of the workpiece. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a ...
