Description
Technical field
It is the utility model relates to stamping die field, in particular to a kind of for the inside edge rolling of automobile seat backboard surrounding
Stamping die.
Background technique
Edge rolling is to produce a main technique for automobile seat backboard, and sliding block is mainly used in previous curling process
Edge rolling is carried out from two sides scraping wings.But when manufacturing Ce Tui edge rolling mechanism, it is easy to happen wrinkling deformation, leads to product
Yields is low, and since the side selection structure complexity needs very high cost, assembly precision requires relatively high.
Utility model content
The purpose of the utility model is to provide one kind can prevent product wrinkling deformation, can reduce production cost and reduces dress
The stamping die for the inside edge rolling of automobile seat backboard surrounding with required precision.
To achieve the goals above, the utility model provides the following technical solutions：
A kind of stamping die for the inside edge rolling of automobile seat backboard surrounding, including upper die and lower die, the upper mold packet
Upper die holder, upper die plate, stripper plate and edge rolling punch-pin are included, the upper die plate is arranged in upper die holder bottom, the edge rolling punch-pin
Be mounted on the two sides of upper die plate bottom, the stripper plate is separately positioned on the outside of edge rolling punch-pin, the lower die include lower die holder,
Lower mold backing plate, material lift plate and edge rolling cavity plate, on the lower die seat, the lower mold backing plate is arranged in lower die holder for the material lift plate installation
On, and it is located at material lift plate two sides, the edge rolling cavity plate is mounted in lower mold backing plate, and setting corresponding with edge rolling punch-pin.
Further, it is provided with pressure plate on the material lift plate and enters son, the material that the pressure plate enters son is hard material.
Further, the material lift plate is installed on the lower die seat by guide post and nitrogen gas spring.
The beneficial effects of the utility model are：
Product is first placed on material lift plate by the utility model in punching press, the work of material lift plate at this moment in nitrogen gas spring
With lower in the state jacked up upwards, and the height jacked up is higher than the height of lower mold backing plate, and then upper mold starts to push, first on
The upper die plate and edge rolling head of mould are in contact with product, and the lower surface of product is pressed on material lift plate by upper die plate and edge rolling punch-pin
On, and the two sides of product are located just at the inside of stripper plate, and upper mold continues to move downward, the guiding of the two sides of product in stripper plate
Under enter in edge rolling cavity plate, then upper die plate and edge rolling punch-pin continue for product to be pressed downward, so that the two sides of product are being rolled up
In cupping tool, slowly inwards along edge rolling cavity plate brake forming, and material lift plate can move downward simultaneously, and stripper plate is in decline
The two sides of product are protected in the process, do not allow product when decline touches on the outside of edge rolling cavity plate, and wrinkling deformation occurs；Work as die sinking
When, upper mold moves upwards, and while upper mold moves upwards, the material lift plate of lower die can withstand on product on stripper plate upwards, so that
Product can be smoothly to top discharge.It can prevent product wrinkling deformation to embody the utility model and have, reduce production
The advantages of cost and reduction assembly precision require.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of the utility model；
Fig. 2 is the structural schematic diagram before the edge rolling of the utility model；
Fig. 3 is the structural schematic diagram after the edge rolling of the utility model.
Specific embodiment
The utility model is further described below in conjunction with attached drawing：
Such as Fig. 1 to a kind of shown in Fig. 3, stamping die for the inside edge rolling of automobile seat backboard surrounding, including upper mold
And lower die, the upper mold include upper die holder 1, upper die plate 2, stripper plate 3 and edge rolling punch-pin 4, the upper die plate 2 is arranged upper
1 bottom of die holder, the edge rolling punch-pin 4 are mounted on the two sides of 2 bottom of upper die plate, and it is convex that the stripper plate 3 is separately positioned on edge rolling
4 outside of mould, the lower die includes lower die holder 5, lower mold backing plate 6, material lift plate 7 and edge rolling cavity plate 8, and the material lift plate 7 is mounted on down
On die holder 5, the lower mold backing plate 6 is arranged on lower die holder 5, and is located at 7 two sides of material lift plate, and the edge rolling cavity plate 8 is mounted on down
On die-cushion plate 6, and setting corresponding with edge rolling punch-pin 4.
Further, it is provided with pressure plate on the material lift plate 7 and enters son 9, the material that the pressure plate enters son 9 is hard material
Material.
Further, the material lift plate 7 is mounted on lower die holder 5 by guide post 10 and nitrogen gas spring 11.
The working principle of the utility model is：
Product is first placed on material lift plate by the utility model in punching press, the work of material lift plate at this moment in nitrogen gas spring
With lower in the state jacked up upwards, and the height jacked up is higher than the height of lower mold backing plate, and then upper mold starts to push, first on
The upper die plate and edge rolling head of mould are in contact with product, and the lower surface of product is pressed on material lift plate by upper die plate and edge rolling punch-pin
On, and the two sides of product are located just at the inside of stripper plate, and upper mold continues to move downward, the guiding of the two sides of product in stripper plate
Under enter in edge rolling cavity plate, then upper die plate and edge rolling punch-pin continue for product to be pressed downward, so that the two sides of product are being rolled up
In cupping tool, slowly inwards along edge rolling cavity plate brake forming, and material lift plate can move downward simultaneously, and stripper plate is in decline
The two sides of product are protected in the process, do not allow product when decline touches on the outside of edge rolling cavity plate, and wrinkling deformation occurs；Work as die sinking
When, upper mold moves upwards, and while upper mold moves upwards, the material lift plate of lower die can withstand on product on stripper plate upwards, so that
Product can be smoothly to top discharge.It can prevent product wrinkling deformation to embody the utility model and have, reduce production
The advantages of cost and reduction assembly precision require.
The above is not limit the technical scope of the present invention, all according to the utility model technical spirit
To any modification, equivalent variations and modification made by above embodiment, the model of the technical solution of the utility model is still fallen within
In enclosing.
