Abstract
The utility model discloses a kind of metal sheet bending groove punching mechanism, including the cope plate being connected with punch-pin, stripper, the concave template for being provided with cavity plate, and sub- stripper, the accommodating chamber matched with described sub- stripper is formed with described stripper, described sub- stripper is arranged in described accommodating chamber and its relative vertical up-or-down movement, and lower pressing spring is provided between described sub- stripper and stripper.The invention also discloses a kind of mould with metal sheet bending groove punching mechanism.Metal sheet bending groove punching mechanism of the present utility model, increase sub- stripper on stripper, while overall step-by-step movement handling process is not changed, carrying out bending groove punch section to wherein certain step increases sub- stripper, the integrality of product, improves product processing quality when effectively improving die sinking.
Description
Technical field
The utility model is related to Stamping Die Technology field, more particularly to a kind of metal sheet bending groove punching mechanism and
Mould.
Background technology
Diel has very big application in metal sheet shaping, still, when processing some special parts, such as needs
Stamp out bending groove, such as deep-slotted chip breaker especially when deep-slotted chip breaker includes pleat, can be ejected easily when being ejected by ejector beam
Deformation, causes product quality to be affected.
Utility model content
The purpose of this utility model is to be directed to technological deficiency present in prior art, and provides a kind of metal sheet bending
Groove punching mechanism and mould.
To realize that the technical scheme that the purpose of this utility model is used is：
A kind of metal sheet bending groove punching mechanism, including be connected with punch-pin cope plate, stripper, be provided with it is recessed
The accommodating chamber matched with described sub- stripper is formed with the concave template of mould, and sub- stripper, described stripper, it is described
Sub- stripper be arranged in described accommodating chamber and its relative vertical up-or-down movement, between described sub- stripper and stripper
It is provided with lower pressing spring.
Described sub- unloading rack is arranged on by guide pillar in described accommodating chamber, it is described push spring be set in it is described
On guide pillar.
The seal face matched with described cavity plate upper surface is formed with the lower surface of described sub- stripper.
A kind of mould with described metal sheet bending groove punching mechanism.
Compared with prior art, the beneficial effects of the utility model are：
Metal sheet bending groove punching mechanism of the present utility model, increases sub- stripper on stripper, is not changing whole
While body step-by-step movement handling process, carrying out bending groove punch section to wherein certain step increases sub- stripper, effectively improves die sinking
When product integrality, improve product processing quality.
Brief description of the drawings
Fig. 1 show the structural representation of metal sheet bending groove diel matched moulds state of the present utility model.
Fig. 2 show the structural representation that metal sheet bending groove diel of the present utility model molds state.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description only to explain the utility model, is not used to limit the utility model.
As depicted in figs. 1 and 2, metal sheet bending groove punching mechanism of the present utility model, including be connected with punch-pin
Cope plate 1, stripper 2, the concave template 3 for being provided with cavity plate 6, and sub- stripper 5 is formed with and institute in described stripper
The accommodating chamber for the sub- stripper matching stated, described sub- stripper is arranged in described accommodating chamber and relative its is vertically transported
It is dynamic, lower pressing spring is provided between described sub- stripper and stripper.When carrying out punching press action, described sub- stripper
Lower surface flushes to prevent from interfering with miscellaneous part with the lower surface of stripper.
Specifically, described sub- unloading rack is arranged on by guide pillar in described accommodating chamber, and described pushes spring housing
It is located on described guide pillar.Meanwhile, it is formed with what is matched with described cavity plate upper surface in the lower surface of described sub- stripper
Matched in seal face, or relatively recessed described stripper with the lower cavity die protruded with relative lower template.
In specific works, sub- stripper is downwardly projected with respect to stripper before matched moulds, and sub- stripper is prior to recessed during matched moulds
Mould, which coordinates, clamps metal blank 10, and then cope plate continuation action carries out punching stretch grooving, when being molded after shaping, ejector beam
4 bottoms for holding bending groove from lower section will expect to eject, simultaneously, although now stripper has been lifted off lower template, but sub
Stripper still retains the compression with lower cavity die, that is, causes metal sheet clamping state ejection, everywhere stress equalization and flexible,
Do not deformed upon when ejection is effectively ensured.
Metal sheet bending groove punching mechanism of the present utility model, increases sub- stripper on stripper, is not changing whole
While body step-by-step movement handling process, carrying out bending groove punch section to wherein certain step increases sub- stripper, effectively improves die sinking
When product integrality, improve product processing quality
Further, the invention also discloses a kind of mould with described metal sheet bending groove punching mechanism
Tool, using the mould, then when carrying out multi-step tension shaping, special processing has been carried out to committed step, is ensureing formation speed
Improve product quality simultaneously.
Described above is only preferred embodiment of the present utility model, it is noted that for the general of the art
For logical technical staff, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as protection domain of the present utility model.
