Description

The outer stiffener component die of a kind of automobile A column
Technical field
The present invention relates to a kind of mould, especially relate to the outer stiffener component die of a kind of automobile A column.
Background technology
This mould is divided into 3 operations before, wants three jig frequencies during production, needs a large amount of operating personnel, the manufacturing cost height, and the manufacturing cycle is long, and production efficiency is not high.As power source, spring or nitrogen spring all can have the requirement of normal damage and periodic replacement to last eccentric swage with spring or nitrogen spring, and maintenance and renewal cost in the production process promote significantly.
Summary of the invention
Purpose of the present invention is exactly to provide stiffener component die outside a kind of easy to maintenance, safe and reliable and lower-cost automobile A column for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
The outer stiffener component die of a kind of automobile A column, comprise upper die and lower die, it is characterized in that, described patrix comprises patrix trimming and piercing die eccentric swage, patrix trimming and piercing die cutter piece, patrix flanging and restriking eccentric swage, patrix flanging and restriking cutter piece, patrix side blow hole eccentric swage, patrix side blow hole cutter piece, upper bolster and upper ejector pin
Described counterdie comprises die shoe, lower mold core and counterdie material jacking mechanism,
Described patrix trimming and piercing die eccentric swage is between upper bolster and lower mold core, described patrix trimming and piercing die cutter piece is positioned at the left side of patrix trimming and piercing die eccentric swage, patrix flanging and restriking eccentric swage is between upper bolster and lower mold core, described patrix flanging and restriking cutter piece is positioned at patrix flanging and restriking eccentric swage right side, described patrix side blow hole eccentric swage is between upper bolster and lower mold core, described patrix side blow hole cutter piece is positioned at eccentric swage right side, patrix side blow hole, and described upper ejector pin is positioned on the upper bolster.
Described lower mold core comprises trimming and piercing die punch, flanging and restriking punch, side blow hole punch, described trimming and piercing die punch is positioned at patrix trimming and piercing die eccentric swage below, described flanging and restriking punch is positioned at patrix flanging and restriking eccentric swage below, and described side blow hole punch is positioned at eccentric swage below, patrix side blow hole.
Described patrix trimming and piercing die eccentric swage, patrix flanging and restriking eccentric swage and patrix side blow hole eccentric swage from left to right are arranged in order.
Compared with prior art, the present invention has economized 2 secondary moulds, has lacked 2 jig frequencies, makes that lathe and personnel and expense are saved; Last eccentric swage uses the upper push rod structure convenient for maintaining, does not need to check or change the binder power source before each the production; Last eccentric swage uses the mould of spring, and is safe and reliable.
Description of drawings
Fig. 1 is the structural representation of this mould.
Among the figure: the 1-die shoe, 2-patrix trimming and piercing die cutter piece, 3-trimming and piercing die punch, 4-patrix trimming and piercing die eccentric swage, the 5-upper ejector pin, 6-flanging and restriking punch, 7-patrix flanging and restriking eccentric swage, 8-patrix flanging and restriking cutter piece, 9-side blow hole punch, 10-patrix side blow hole eccentric swage, 11-upper bolster, 12-patrix side blow hole cutter piece.
The specific embodiment
