The workpiece punching die is reasonable in structure, convenient to operate and stable in working, produced workpieces are good and free of deformation, the punching effect on cylindrical workpieces with small pipe diameters and large hole pinches is good, and the workpiece punching die is suitable for mass production.

Description

A kind of workpiece punching die
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of workpiece punching die.
Background technology
In production process, usually need workpiece is carried out to punch work, the mould that typically uses both sides punching simultaneously carries out punch work, when the cylindrical work pieces that but common punching die is less to caliber, pitch-row is larger carries out stamping-out, mould usually deforms in its punching intersection, make mould normally to use, cause the workpiece of producing that undesirable deformation can occur.
Summary of the invention
Goal of the invention: purpose of the present invention just is to provide a kind of workpiece punching die.
Technical scheme:For achieving the above object, the present invention has taked following technical scheme:
A kind of workpiece punching die, it is characterized in that: comprise cope match-plate pattern, lower bolster, described cope match-plate pattern, be connected with guide pillar between lower bolster, described cope match-plate pattern bottom is provided with upper male mould straight down, described lower bolster is provided with lower punch, described lower punch faces described upper male mould, described upper male mould and the lower punch symmetry 3-15 degree that slopes inwardly, be provided with the die of horizontal direction between described upper male mould and lower punch, described die is provided with the traveller of vertical direction away from an end of described guide pillar, the both sides of described traveller are provided with sliding sleeve, described traveller bottom is provided with spring, described spring connects described traveller and lower bolster, described lower punch both sides are provided with stripper, described stripper is located at the bottom of described die, described bolster is pressed down slip to die jointly, described punching die also comprises bottom plate, described bottom plate is located at described lower punch both sides, connect described polyurethane block and lower bolster.
It also comprises polyurethane block, and described polyurethane block is located at described lower punch both sides, is positioned at the bottom of described stripper.
Described cope match-plate pattern is provided with upper mounted plate, and the fixed plate lays respectively at the both sides of described upper male mould.
Described guide pillar is arranged with guide pin bushing outward.
Be made as inclined-plane in the middle of described bottom plate.
The size of described upper male mould is greater than the size of described lower punch.
In the middle of described die, one section is empty, without cutting edge.
In the middle of described polyurethane block and stripper, be to open structure.
operation principle:during mold work of the present invention, need coordinate forcing press jointly to use, during to the workpiece punching, workpiece is placed in die, under the effect of forcing press, upper male mould contacts with sliding sleeve respectively at workpiece with lower bolster, and descend along with the decline of cope match-plate pattern, in the decline process of cope match-plate pattern, upper male mould and lower punch carry out upper and lower two groove punchings to workpiece jointly, after punching finishes, upper male mould is up, and die, workpiece, slide over and jointly under the elastic force effect of spring and polyurethane block upwards float, after rising to the extreme position of stripper, open stripper, workpiece after punching completes can draw off, thereby complete the punching operation of workpiece.
Beneficial effect:Adopt the present invention of technique scheme to have the following advantages:
The present invention is rational in infrastructure, easy to operate, and the workpiece that working stability is produced is good, and without distortion, the stamping-out of the cylindrical work pieces less to caliber, that pitch-row is larger is effective, is applicable to producing in enormous quantities.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-lower bolster, 2-guide pillar, 3-polyurethane block, 4-stripper, 5-lower punch, 6-guide pin bushing, 7-cope match-plate pattern, 8-upper mounted plate, 9-upper male mould, 10-workpiece, 11-traveller, 12-sliding sleeve, 13-die, 14-bottom plate, 15-spring.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further set forth.
As shown in the figure: a kind of workpiece punching die of the present invention, it is characterized in that: comprise cope match-plate pattern 7, lower bolster 1, described cope match-plate pattern 7, be connected with guide pillar 2 between lower bolster 1, described cope match-plate pattern 7 bottoms are provided with upper male mould 9 straight down, described lower bolster 1 is provided with lower punch 5, described lower punch 5 faces described upper male mould 9, described upper male mould 9 and the lower punch 5 symmetries 3-15 degree that slopes inwardly, be provided with the die 13 of horizontal direction between described upper male mould 9 and lower punch 5, described die 13 is provided with the traveller 11 of vertical direction away from an end of described guide pillar 2, the both sides of described traveller 11 are provided with sliding sleeve 12, described traveller 11 bottoms are provided with spring 15, described spring 15 connects described traveller 11 and lower bolster 1, described lower punch 5 both sides are provided with stripper 4, described stripper 4 is located at the bottom of described die 13, it also comprises polyurethane block 3, described polyurethane block 3 is located at described lower punch 5 both sides, be positioned at the bottom of described stripper 4, it also comprises bottom plate 14, described bottom plate 14 is located at described lower punch 5 both sides, connect described polyurethane block 3 and lower bolster 1, in the middle of described polyurethane block 3 and stripper 4, be to open structure.
