Description
Technical field
The present invention relates to automotive field, in particular to a kind of automobile metal plate work stamping die.
Background technique
Press machine is also known as press machine, is the equipment for carrying out pressure processing to material, working principle is generally by mold
The folding of punch-pin and cavity plate is driven under the action of punching press power, and the original part in mold is cut, punching, the system such as stretching
Journey, to form stamping parts.Stamping die is mainly used in Cold Press Working, is at room temperature, to be pressed using being mounted on
Mold on power machine applies pressure to original part, it is made to generate separation or plastic deformation, thus a kind of pressure of part needed for obtaining
Processing method.
Currently, with industrial continuous development and progress, in order to improve the quality of industrial products, Production of Stamping Die
Also it is widely used in a variety of applications.Wherein, in automobile manufacture industry, traditional stamping die when in use, usually will
Metal plate original part is placed on the cavity plate of mold, and metal plate original part is then allowed to generate deformation by the pressure of punch-pin.Using punching press
When mold produces sheet metal component, various change can occur for the sheet metal component for generating deformation.And due to sheet metal component generate deformation when
Time can generate stronger tension, so biggish frictional force can be generated between sheet metal component and the inner wall of mold inner groovy, in this way, In
Certain damage can be not only caused after punch forming on mold, influences precision, while after also will affect punch forming
Sheet metal component is taken.
Summary of the invention

Female mold support roller drive rod 802 is pulled to the outside of bearing platform 4, the first upper connecting rod 1202 and the second upper connecting rod 1205 by connecting rod 1206
Male mold support roller drive rod 1002 is gradually pulled to the outside of shock testing machine 5, wherein the female mold support roller drive rod 802 of two sides is distinguished
Two female mold support rollers 801 are pulled between 6 bottom surface of cavity plate and 1 top surface of lower die holder and correspond to the inclined-plane of cavity plate 6 in conjunction with bottom surface
At position, two male mold support rollers 1001 are pulled to 7 top surface of punch-pin and upper mold respectively by the male mold support roller drive rod 1002 of two sides
At the inclined-plane and top surface binding site for corresponding to punch-pin 7 between 3 bottom surfaces of seat, at this time just at punch forming completion status, then
It only needs to continue to be downwardly applied to after certain pressure, female mold support roller 801 is separated from each other with 6 bottom surface of cavity plate, male mold support roller
1001 are separated from each other with 7 top surface of punch-pin, cavity plate retraction spring 901 by cavity plate 6 quickly top to being bonded with lower die holder 1, by its with
Molding sheet metal component quickly separates, while punch-pin 7 is also quickly contracted to and pastes with upper die holder 3 by punch-pin retraction spring 1101
Close, the bottom of punch-pin 7 quickly be separated from each other at the top of sheet metal component, the two is synchronization action, and the sheet metal component after completing is just
Being is entirely active state, can quick and portably be taken.
Upper die holder 3 in the present embodiment drive shock testing machine 5 and punch-pin 7 together downlink while, linkage mechanism 12 will drive
Female mold support mechanism 8 and male mold support mechanism 10 act together, when punch forming terminates, female mold support mechanism 8 and convex
Mould supporting mechanism 10 respectively disappears to the support of cavity plate 6 and punch-pin 7, at this point, work of the cavity plate 6 in cavity plate cam mechanism 9 and gravity
The bottom surface that cavity plate 6 is come downwards under is bonded with the top surface of lower die holder 1, and punch-pin 7 overcomes weight under the action of punch-pin cam mechanism 11
The top surface that power goes upward to punch-pin 7 is bonded with the bottom surface of upper die holder 3, in this manner it is ensured that when punch forming acts completion,
Cavity plate 6 and the equal snapback of punch-pin 7, so as to avoid the punching press size because of sheet metal component caused by excessively pressing that mistake occurs, together
When can also reduce attack time to mold, to reduce the abrasion of mold, but also the demoulding of sheet metal component can be realized automatically,
Facilitate taking for sheet metal component.
Meanwhile the present embodiment is by being designed as inclined-plane for the lower sides of cavity plate 6, and the upper portion side wall of punch-pin 7 is also set
It is calculated as inclined-plane, space can be provided in this way for female mold support mechanism 8 and the movement of male mold support mechanism 10；The fillet added on the one hand can
To reduce the abrasion between components, the retraction of cavity plate 6 and punch-pin 7 and support part on the other hand can also be made more smooth steady,
Another further aspect also facilitates the reset of cavity plate 6 and punch-pin 7.
Moreover, on the one hand the cam mechanism added can provide driving force for the retraction of cavity plate 6 and punch-pin 7, on the other hand also
It can prevent cavity plate 6 and punch-pin 7 from deviating from out of bearing platform 4 and shock testing machine 5；The limited post added facilitates retraction spring installation and consolidates
It is fixed；Whether adding pressure sensor 13, to detect this mold working properly, in case unrepairable damage occurs for mold.
