Abstract
The utility model discloses a punching die compound die positioning piece which comprises a centering rod, an elastic part, and a link block in precision fit with a punching protruding die holder, wherein, the centering rod consists of a conehead adapted to the punching concave groove edge opening and an integrated round bar, the center line of the conehead is coincident with that of the round bar, the round bar of the centering rod is in precision fit with the center hole arranged at the upper part of the link block, the lower part of the center hole is communicated with a venthole, and the elastic part is positioned between the conehead of the centering rod and the link block. The punching die compound die positioning piece with the structure realizes positioning by replacing a plunger tip in the positioning process, thereby not only improving the efficiency and shortening the punching hole manufacturing cycle but also guaranteeing the punching accuracy of the punching die.
Description
Technical field
The utility model relates to perforating die, especially relates to a kind of perforating die matched moulds keeper.
Background technology
Perforating die is made up of upper die and lower die usually at present, patrix is a die, counterdie is a punch, and punch comprises convex mould base and drift, and punch length is generally 70～90 millimeters, after the upper die and lower die digital control processing of perforating die is good, upper and lower mould need be closed hydraulic press, drift be aimed at die, after working good, gum fixed head down, following hydraulic press is opened mould, and last drilling machine is put screw hole on mould, more inclined to one side dress fixed head is struck down, glue is rooted out, the tapping of on mould, punching, the press of reoiling is aimed at die with drift again, with screw the drift fixed head is fastened on the mould then, following hydraulic press, upper and lower mould is opened, and last drilling machine is beaten two dowel holes of fixed head.Such perforating die matched moulds locate mode, because must be gapped between drift and die, the center line of drift is difficult to find accurately the center line of die, cause operation various, rigging error is bigger, has not only influenced perforating die and has made progress, and be difficult to guarantee the punching precision of perforating die.
The utility model content
Technical problem to be solved in the utility model is: a kind of perforating die matched moulds keeper is provided, and this perforating die matched moulds keeper not only can shorten the perforating die fabrication cycle, and can guarantee the punching precision of perforating die.
Solve this technical problem, the technical solution of the utility model is: a kind of perforating die matched moulds keeper, it is formed by centering bar, elastomeric element with the link block of piercing punch seat precision-fit, the centering bar is by forming with punching concave die cutting edge conehead that adapts and the round bar that forms one, the center line of conehead and the center line of round bar coincide, the centre bore precision-fit that the round bar of described centering bar and described link block top are provided with, the bottom of centre bore communicates with passage, and described elastomeric element is between the conehead and link block of centering bar.
The round bar stage casing of described centering bar is provided with spacing stroke groove, and the top of described coupling block is provided with perpendicular to the centering bar that makes of centering bar center line can go here and there the stop screw of LAP up and down back and forth.
The outer surface of upper of described link block is with a sheath.
Described elastomeric element is the compression spring.
Described sheath is a stainless steel part.
The top of the conehead of described centering bar is a circular cone.
The top of described centering bar conehead is positive rectangular pyramid or positive pentagonal pyramid or positive hexagonal pyramid.
The utility model adopts the perforating die matched moulds keeper of this structure, when the perforating die matched moulds is located, it replaces drift to position, link block inserts the drift fixed head, last hydraulic press, by circular cone cooperate the center of quick alignment holes with die, the direct pin-and-hole of fixed processing piece behind the following press is put into drift in the holder and to be assembled.Compared with prior art, its length can the specific impulse head length, and is easy to operate, can feel relieved fast and accurately, omitted multiple working procedure, can not only raise the efficiency, and shortens the perforating die fabrication cycle, and can guarantee the punching precision of perforating die.
Description of drawings
Below in conjunction with accompanying drawing a kind of perforating die matched moulds of the utility model keeper is done explanation in further detail;
Fig. 1 is a kind of perforating die matched moulds of the utility model keeper structural representation;
Fig. 2 is the structural representation of link block shown in Figure 1;
In Fig. 1, Fig. 2,1, centering bar; 2, compression spring; 3, sheath; 4, stop screw; 5, link block; 6, centre bore; 7, passage; 8, stop screw hole.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of perforating die matched moulds keeper is made up of centering bar 1, compression spring 2, sheath 3, stop screw 4 and link block 5, centering bar 1 is made up of conehead and the round bar that forms one, the center line of conehead and the center line of round bar coincide, the top of conehead and punching concave die cutting edge adapt, its shape can be circular cone, can be positive rectangular pyramid or positive pentagonal pyramid or positive hexagonal pyramid, and the round bar stage casing has spacing stroke groove; Link block 5 is step-like, link block 5 upper part diameter are greater than the diameter of link block 5 bottoms, link block 5 bottoms and piercing punch seat precision-fit, link block 5 tops have vertical accurately machined centre bore 6, the bottom of centre bore 6 communicates with passage 7, the top of coupling block 5 has the stop screw hole 8 perpendicular to centering bar 1 center line, the round bar of centering bar 1 and centre bore 6 precision-fit on link block 5 tops, and compression spring 2 is between the conehead and link block 5 of centering bar 1.Sheath 3 is made by stainless steel, be placed in the top outer round surface of link block 5, to compress spring 2 covers, make perforating die matched moulds keeper seem attractive in appearance, stop screw 4 is screwed on the stop screw hole 8 of coupling block 5, make stop screw 4 stretch out stop screw hole 8, but its end face not with centering bar 1 round bar on spacing stroke groove contact, keep centering bar 1 can go here and there LAP up and down back and forth, the bar of feeling relieved so just can link to each other with link block, and the bar of avoiding feeling relieved separates the inconvenience that causes with link block.
During use, perforating die matched moulds keeper at first is assembled on the piercing punch seat, last hydraulic press, by circular cone cooperate the center of quick alignment holes with die, the direct pin-and-hole of fixed processing piece behind the following press is put into drift in the holder and to be assembled.Press down centering bar 1, compression spring 2 is compressed, and centering bar 1 descends along center line, and the gas in the centre bore 6 of link block 5 is discharged by passage 7, thereby perforating die matched moulds keeper adjustable height, its length is can the specific rigidity drift long, can increase the gap between piercing punch and the punching concave die, is convenient to operation, omitted multiple working procedure, can not only raise the efficiency, shorten the perforating die fabrication cycle, and can guarantee the punching precision of perforating die.
