Description
Technical field
The utility model belongs to Stamping Die Technology field, more particularly, to a kind of diel of chain-sheet of chain.
Background technology
The continuous punching of conventional chain or chain piece is into mould mode：Punching → squeeze hole → blanking；Correspondingly, common punching press
The design feature of mould is that punching needle, correcting nail, crowded hole pin and blanking punch are all fixed on train wheel bridge, and train wheel bridge
It is fixed on again in top mold frame, correspondingly, stripper plate is fixed on lower mold holder, and all punching needles are in the guide hole of stripper plate
Slide up and down, so that when punching needle wears, correcting is followed closely and squeezes hole pin followed by abrasion in the lump；Further, since in punching, squeeze
Under three workshop sections in hole and blanking, existing three active forces are consistent to the action direction of chain or chain piece, will cause chain or chain
The flatness of piece is not good enough.
Utility model content
The purpose of this utility model is, for the deficiencies in the prior art, there is provided a kind of punching press of chain-sheet of chain
Mould.
Therefore, above-mentioned purpose of the present utility model is achieved through the following technical solutions：
A kind of diel of chain-sheet of chain, the diel of the chain-sheet of chain includes top mold frame and lower mold holder, described
Train wheel bridge, stripper plate and lower template are set gradually between top mold frame and lower mold holder from top to bottom, the material strip of the diel enters
Material mouth sets material lift pin, and described material lift pin one end is rotatablely connected with diel, and groove is set in the material lift pin.
While using above-mentioned technical proposal, the utility model can also be used or combined using further below
Technical scheme：
Preferably, one end of the material lift pin is articulated and connected with diel.
Preferably, diel sets pin with spacing material lift pin at material strip charging aperture.
Preferably, the stripper plate is connected in top mold frame, and can be moved up and down relative to top mold frame.
Preferably, spring bumper cover is set in the top mold frame, sets spring to cause between the spring bumper cover and stripper plate
Stripper plate can move up and down relative to top mold frame.
Preferably, the spring bumper cover is arranged on the top of top mold frame.
Preferably, dent is set in the lower template.
Preferably, upper padding plate is set between top mold frame and train wheel bridge, and lower template and lower mold holder support set lower bolster.
Preferably, train wheel bridge sets gradually punching needle and finishing point on feedstock direction.
Preferably, correcting is set to follow closely on stripper plate, the correcting nail uses ultrashort design structure.
The utility model provides a kind of diel of chain-sheet of chain, and the material strip charging aperture of the diel, which is set, to be had
The material lift pin of groove, the material lift pin can be with up and down, and so open material strip groove is easy to coolant flow, if producing burr
Bits can wash out in time, reduce part and may be because that burr bits produce impression；Stripper plate is fixed in top mold frame, and can more than
Lower activity, elastic compression material strip during punching press, reduce position movement of the material strip in punching press loading process, improve positioning precision and
Reduce probably due to material strip problem unbalance stress.Correcting nail uses ultrashort design structure to reduce spillage of material, and is fixed on de-
As stripper plate moves up and down on flitch, so that correcting nail need not follow punching press concave-convex mold that height occurs and be ground, and
Know that replacing all without grinding length, reduces the workload to repair a die.All concave-convex molds use quick-disassembly structure, wherein lower mould is not required to
Form removal frame is wanted to change concave-convex mold, high-stroke punch press directly changes concave-convex mold in bed even without mould is pulled down, and improves
Dismount the operating efficiency of mould.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of the diel of chain-sheet of chain provided by the utility model.
Embodiment
The utility model is described in further detail with specific embodiment referring to the drawings.
A kind of diel of chain-sheet of chain, including top mold frame 1 and lower mold holder 2, from upper between top mold frame 1 and lower mold holder 2
Train wheel bridge 3, stripper plate 4 and lower template 5 are set gradually under, the material strip charging aperture of diel sets material lift pin 6, material lift pin 6
One end is rotatablely connected with diel, and groove 601 is set in material lift pin 6；In the present embodiment, diel is in material strip charging aperture
Place sets pin with spacing material lift pin, certainly in other embodiments, can also be by the way that one end of material lift pin is hinged into punching press
Mode on mould is attached, and certainly similar can cause material lift pin one end and any connection of diel rotation connection
Mode is all possible, and is belonged in the scope of protection of the utility model.
Stripper plate 4 is connected in top mold frame 1, and can be moved up and down relative to top mold frame, in the present embodiment, top mold frame
Spring bumper cover 7 is set on 1, sets spring to allow stripper plate 4 relative in top mold frame 1 between spring bumper cover 7 and stripper plate 4
Lower motion.By the way that stripper plate 4 is connected in top mold frame 1, and allow to move up and down relative to top mold frame, so as to logical
The mating reaction crossed between stripper plate 4 and train wheel bridge 3 compresses material.Spring bumper cover 7 is arranged on the top of top mold frame, exists certainly
In other embodiment, the mode of other fixation stripper plates can also be set, it is only necessary to meet that stripper plate is connected in top mold frame, and
And can relative to top mold frame move up and down can, and meet this purpose arbitrary structures set should all belong to this practicality
In new protection domain.
Dent 8 is set in lower template 2, so that the action direction of the active force of dent workshop section and punching workshop section, essence
Repair the direction contrast of the active force of workshop section and blanking workshop section so that the flatness of chain piece or chain also can be more preferable.
Upper padding plate 9 is set between top mold frame 1 and train wheel bridge 3, and lower template 5 and the support of lower mold holder 2 set lower bolster 10.
Train wheel bridge 3 sets gradually punching needle 11 and finishing point 12 on feedstock direction.
Correcting is set to follow closely 13 on stripper plate 4, correcting nail 13 uses ultrashort design structure.
The present embodiment provides a kind of diel of chain-sheet of chain, and the material strip charging aperture of diel sets tool reeded
Material lift pin, the material lift pin can be with up and down, and so open material strip groove is easy to coolant flow, can be with if producing burr bits
Wash out in time, reduce part and may be because that burr bits produce impression；Stripper plate is fixed in top mold frame, and can be lived up and down
It is dynamic, elastic compression material strip during punching press, position movement of the material strip in punching press loading process is reduced, improves positioning precision and reduction
Probably due to material strip problem unbalance stress.Correcting nail uses ultrashort design structure to reduce spillage of material, and is fixed on stripper plate
On move up and down with stripper plate, so that correcting nail need not follow punching press concave-convex mold that height occurs and be ground, and know
Change all without grinding length, reduce the workload to repair a die.All concave-convex molds use quick-disassembly structure, wherein lower mould need not be torn open
Mould bases can change concave-convex mold, and high-stroke punch press directly changes concave-convex mold in bed even without mould is pulled down, and improves dismounting
The operating efficiency of mould.
Above-mentioned embodiment is used for illustrating the utility model, preferred embodiment only of the present utility model, and
It is not that the utility model is limited, it is new to this practicality in spirit of the present utility model and scope of the claims
