Abstract

The invention provides a double-acting side-pushing bend-forming die. An upper base plate, an upper clamping plate, a stop plate and a stripping plate are sequentially mounted below an upper die base;a lower die plate and a lower base plate are sequentially mounted above the upper die base; an inner guide column is arranged in the upper clamping plate, the upper clamping plate and the upper baseplate are fixed to the upper die base, the upper die base and the upper clamping plate slide upwards and downwards along the inner guide column, and the inner guide column penetrates through the stripping plate and the lower die plate to realize a guide function; a first punch and a second punch are arranged in the upper clamping plate and penetrate through the stripping plate to enter the lower die plate and drive a forming block and a side-pushing block to move to realize side-pushing formation; and reset springs are arranged in the forming block and the side-pushing block and abut against spring stop blocks, and when the first punch and the second punch move upwards, the forming block and the side-pushing block restore under the effect of the elastic force of the reset springs. The double-acting side-pushing bend-forming die has the beneficial effects of being able to overcome the process difficulty of side-pushing bending and edge covering, realize normal automatic stripping and guarantee continuous production.

Description

technical field

[0001] The invention relates to the field of parts processing, in particular to a double-action side push bending mold. Background technique

[0002] Such as Figure 1-4 As shown, when processing parts with complex shapes, because there are many molding processes, if engineering molds are used for production, more personnel and machines are required. The production cost is too high, there are many processes, and the production efficiency is very low, which cannot meet normal production. need.

[0003] For this, progressive die continuous stamping production can be used to meet production needs, such as Figure 1-4 Parts process analysis, determined using the following Figure 5 The process shown in the partial process flow of the progressive die; the difficulty of this process is that the mold structure of side push bending and hemming needs to realize the hemming forming and at the same time, the material should be returned normally to ensure continuous pro...

Embodiment Construction

[0031] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] Such as Figure 6-11 As shown, a double-action side push bending mold structure includes an upper mold base 1, an upper backing plate 2, an upper splint 3, a stopper plate 4, a stripping plate 6, and a lower die plate connected sequentially from top to bottom. 8. The lower backing plate 9 and the lower mold base 11; the upper splint 3 is provided with an inner guide column 19, the upper splint 3 and the upper backing plate 2 are fixed on the upper mold base 1 together, and the upper mold base 1 and the upper splint 3 are along the inner The guide post 19 slides up and down, the inner guide post 19 passes through the stripper plate 6 and the lower template 8 to provide guidance for the mold, and the upper splint 3 is also provided with a punch 5 and a punch 20, and the punch 5 and the punch 20 pass through the stripper The mat...
