Description
Technical field
The utility model relates to the manufacture field of auto parts machinery, is specifically related to a kind of trimming and piercing die.
Background technology
In fields such as automobile makings, often need to carry out flange, punching and deburring operation to large area plate, originally, the processing method of ground passage stiffener is: stretching, deburring, punching, present deburring and punching complete in same operation, production efficiency is not high, in order to reduce production process, enhance productivity, people start to carry out deburring and punch operation to plate with trimming and piercing die simultaneously.Existing trimming and piercing die comprises upper die and lower die and between upper and lower mould, is used for repairing the insert on plate border.Existing insert is as a whole, different inserts is just needed for different plates, therefore need to do multiple insert, production cost is high, cause certain waste of material, again because insert can produce extrusion abrasion in contacting with plate, upon wear can only integral replacing, insert for non-wearing part causes waste, makes the mold use life-span low.
Utility model content
The purpose of this utility model is to provide a kind of trimming and piercing die, causes production cost high, the problem that service life is low to solve existing trimming and piercing die because insert adopts Integral-structure type design.
The technical scheme adopted to realize the purpose of this utility model is: a kind of trimming and piercing die, and comprise upper die and lower die and be used for repairing the insert on plate border between upper and lower mould, described insert comprises several patrix inserts and several counterdie inserts; Be provided with upper bolster bottom described patrix, the bottom of upper bolster is provided with punch, punch is provided with drift and guide pillar, and patrix, upper bolster are connected by the first bolt with punch; Described upper bolster comprises upper die plate, and patrix insert is located at bottom upper die plate, is provided with eccentric swage in patrix insert, is provided with several springs between eccentric swage and upper die plate; Described counterdie top is provided with die shoe, and die shoe is provided with die, and counterdie, die shoe are connected by the second bolt with die; Die is provided with the punching coordinated with drift and the guide pin bushing coordinated with guide pillar, and described counterdie insert is located at the upper surface of die shoe, and the arranged outside of described die has stripper and waste material box, and stripper and waste material box are connected on die shoe.
Indication plate refers to that on automobile, shape is the parts of tabular herein.
Operation principle: during use, is connected with punch and die with counterdie insert respectively by patrix insert.Forcing press pressure upper die and lower die, under the guiding of guide pillar guide pin bushing, drift and plate push against and continue downward punching press and finally make drift pass plate and punching offsets.Plate under the pressure effect of upper and lower mould according to the shape of insert by unnecessary corner parts excision and under gravity waste material is exported in waste material box by the stripper on die shoe.
Compared with prior art, the beneficial effects of the utility model are: 1. insert comprises several patrix inserts and several counterdie inserts, can change the insert of wearing and tearing pointedly and not need to change whole insert, reduce cost, and improve die life.2. be provided with several springs between eccentric swage and upper die plate, buffering upper die plate is added in the power on eccentric swage, reduces wearing and tearing, improves the mold use life-span.
Preferably, described patrix insert is made up of insert A, insert B and insert C and insert D, removably connects between insert, and convertiblely between each insert be combined into various shape, conveniently deburring is carried out to various variform plate, save the production time, improve production efficiency.The insert of specifically wearing and tearing can be replaced when insert is worn and torn, before avoiding need whole insert to replace, reduce production cost, improve die life.
Preferably, described counterdie insert is made up of insert E, insert F and insert G, removably connect between insert, and convertiblely between each insert be combined into various shape, the insert of specifically wearing and tearing can be replaced when insert is worn and torn, before avoiding need whole insert to replace, reduce production cost, improve die life.
Preferably, described punch is provided with several forming cavities B, forming cavity A, conveniently punching is carried out to different sheet metal components, save the production time, improve production efficiency.
Preferably, described stripper is tilted to down the both sides being placed in die length direction, waste material box is placed in the below of stripper and the length of waste material box is greater than the length of stripper, waste material is facilitated to enter waste material box by stripper, make almost there is no excess waste between upper and lower mould, both ensure that environment neatly turn avoid waste of material.
