Abstract
The invention discloses one and turn in advance shaping top nest punch assemblies, comprise piercing punch, turn in advance formula punch, pressure source cover, limiting plate and holder, piercing punch is fixedly connected on holder, pressure source cover is nested with in the outside lower end of piercing punch, turning in advance formula punch is nested with in piercing punch outside, and be placed in pressure source cover top, the top of piercing punch is lower than the top of turning in advance formula punch, turning in advance formula punch is fixedly connected with piercing punch, turn in advance section diameter under formula punch and be greater than section diameter, limiting plate one end be provided with turn in advance formula punch on the circular hole that matches of section diameter, limiting plate one end is nested with is turning over formula punch outside in advance, the other end is fixedly connected on holder, turn in advance formula punch inside because piercing punch caves in to be placed in, make to turn in advance formula punch and first contact with product, the punching again of first flange, thus avoid the unnecessary wearing and tearing of drift and die case wearing and tearing, improve drift life-span and die case life-span.
Description
Technical field
The invention belongs to machine casting and processing technique field, be specifically related to one and turn in advance shaping top nest punch assemblies.
Background technology
First punching flange again when product punching, but because drift cutting edge contacts with product in advance, and be local contact, cause repeatedly serious wear after stamping-out, after drift damages, can directly affect the life-span of die case, accelerate die case and damage, after punching, product is jagged, drift is easy to wear, and die case is easy to wear.
Summary of the invention
Technical problem to be solved by this invention is to provide one and turns in advance shaping top nest punch assemblies, the punching again of first flange, thus can avoid the unnecessary wearing and tearing of drift and die case wearing and tearing.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
One is turned over shaping top nest punch assemblies in advance, comprise piercing punch, turn in advance formula punch, pressure source cover, limiting plate and holder, piercing punch is fixedly connected on holder, pressure source cover is nested with in the outside lower end of piercing punch, turning in advance formula punch is nested with in piercing punch outside, and be placed in pressure source cover top, the top of piercing punch is lower than the top of turning in advance formula punch, turning in advance formula punch is fixedly connected with piercing punch, turn in advance section diameter under formula punch and be greater than section diameter, limiting plate one end be provided with turn in advance formula punch on the circular hole that matches of section diameter, limiting plate one end is nested with is turning over formula punch outside in advance, the other end is fixedly connected on holder.
Described piercing punch epimere is provided with at least two keyways, is provided with corresponding screw described turning in advance on formula punch, turns in advance formula punch and is screwed and is connected with piercing punch.
Described pressure source cover is polyurethane sleeve or silica gel spring.
Described limiting plate is Z-type limiting plate.
Described holder bottom is provided with holder backing plate.
Beneficial effect of the present invention: adopt the shaping top nest punch assemblies of turning in advance of the present invention, because caving in to be placed in, piercing punch turns in advance formula punch inside, making to turn in advance formula punch first contacts with product, the punching again of first flange, thereby avoid the unnecessary wearing and tearing of drift and die case wearing and tearing, improve drift life-span and die case life-span, reduce mold repair time and expense; Eliminate product cracking, Burr Problem, and then improve product and turn over and rush quality, improve part accuracy.

Detailed description of the invention
As shown in Figure 1, one is turned over shaping top nest punch assemblies in advance, comprise piercing punch 1, turn in advance formula punch 2, polyurethane pressure source cover 6, limiting plate 3, holder 4 and holder backing plate 5, piercing punch 1 is fixedly connected on holder 4, polyurethane pressure source cover 6 is nested with in the outside lower end of piercing punch 1, turning in advance formula punch 2 is nested with in piercing punch 1 outside, and be placed in polyurethane pressure source and overlap 6 tops, the top of piercing punch 1 is lower than the top of turning in advance formula punch 2, piercing punch 1 epimere is provided with at least two keyways 9, on formula punch 2, be provided with corresponding screw 12 described turning in advance, turning in advance formula punch 2 is fixedly connected with piercing punch 1 use screw 7, turn in advance 2 times section diameters of formula punch and be greater than section diameter, Z-type limiting plate 3 one end be provided with turn in advance formula punch 2 on the circular hole 10 that matches of section diameter, the other end is provided with the circular hole 11 matching with screw 8, Z-type limiting plate one end is nested with is turning over formula punch 2 outsides in advance, and the other end is fixedly connected on holder 4 with screw 8.
When product, change the punching process of drift, change punch structure according to punching process, piercing punch 1 caves in to be placed in and turns in advance formula punch 2 inside, turn in advance formula punch 2 and first contact with product, the punching again of first flange, thus avoid unnecessary wearing and tearing and the die case of drift of piercing punch 1 to wear and tear.
