Abstract

The utility model relates to a mould for compressing and forming the longitudinal wall of a molded piece, which comprises an upper mould and a lower mould; an air cushion is arranged between the upper mould and the lower mould; the bottom end of the upper mould is connected with a pressing block; and a spring is connected between the pressing block and the bottom end of the upper mould. The mould for compressing and forming the longitudinal wall of the molded piece can effectively solve the problem that the longitudinal wall of a beam part manufactured from a high-strength steel sheet rebounds.

Description

A kind of mould that is used for the compression forming of product longitudinal wall
Technical field
The utility model relates to a kind of mould that is used for the compression forming of product longitudinal wall.
Background technology
High-strength steel sheet has been widely used in automobile making, and the beam piece that high-strength steel sheet is made is after drawing, and longitudinal wall can produce bounce-back, and existing mould can not effectively solve aforesaid longitudinal wall bounce-back problem.
The utility model content
Goal of the invention of the present utility model is to provide a kind of mould that is used for the compression forming of product longitudinal wall, can effectively solve the beam piece longitudinal wall bounce-back problem that high-strength steel sheet is made.
Realize the technical scheme of the present utility model purpose:
A kind of mould that is used for the compression forming of product longitudinal wall comprises upper die and lower die, it is characterized in that: be provided with air cushion between the upper die and lower die, the bottom of patrix is connected to binder block, is connected to spring between binder block and the patrix bottom.
Be connected to spring between air cushion bottom and the counterdie top.
The bottom of air cushion and the top of counterdie are the stairstepping that cooperatively interacts.
The beneficial effect that the utlity model has:
Patrix of the present utility model bottom is connected to binder block, be connected to spring between binder block and the patrix bottom, be provided with air cushion between the upper die and lower die, can effectively strengthen the stroke of compression forming, thereby increasing forming force, as shown in Figure 2, efficiently solve the beam piece longitudinal wall bounce-back problem that high-strength steel sheet is made, improved the Forming Quality of high-strength steel sheet.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 utilizes the utility model to the product shape contrast figure before and after the product compression forming.
The specific embodiment
As shown in Figure 1, be provided with air cushion 4 between patrix 1 and the counterdie 6, the bottom of patrix is connected to binder block 3, is connected to spring 2 between binder block and the patrix bottom.Be connected to spring 5 between air cushion bottom and the counterdie top, the bottom of air cushion and the top of counterdie are the stairstepping that cooperatively interacts.
During compression forming, product 7 is placed on the air cushion 4, the longitudinal wall of product 7 is positioned at the below of binder block 3.Patrix is descending, and binder block 3 is with after counterdie 6 contacts, and patrix also can continue descending LAP, increases forming force, effectively discharges the stress of product longitudinal wall, and simultaneously, air cushion is also descending with patrix, and air cushion plays cushioning effect between upper die and lower die.

Claims (3)
