Abstract

The invention relates to a die for trimming, punching and separating automotive covering parts. The die comprises an upper die and a lower die, wherein the upper die comprises an upper die base, a trimming die insert, a piercing punch, an intermediate cut-off tool and an upper material pressing body; and the lower die comprises a lower die base, a trimming punching separation punch and die insert, a scrap material cut-off tool, a lower material returning body, a material returning body guide block, a material returning body limiting bolt, a spring, a push rod and a scrap material box. The invention also discloses a method for trimming, punching and separating the automotive covering parts, the separation of left parts and right parts is finished while the automotive covering parts are trimmed and punched; after the automotive covering parts are trimmed, punched and separated, the cut-off scrap material in the middle is pushed out by the lower material returning body; and the separated scrap materials at the front end and the rear end naturally separate and slip out, so that the separated scrap material can be conveniently and smoothly removed.

Description

A kind of automobile panel deburring, punching, peel of mould and method
Technical field
The present invention relates to a kind of automobile panel deburring, punching, peel of mould and method, belong to the cold punching technology field.
Background technology
The mould design and manufacturing technology is the core technology of modern punching production, and along with the fast development of modern manufacturing industry, it is efficient, safe and reliable that automobile industry is constantly being pursued production.Generally, for automobile panel, behind drawing and forming, need accomplish follow-up deburring in two steps, punching and separation have had a strong impact on operating efficiency.
Summary of the invention
Technical problem to be solved by this invention provides a kind of automobile panel deburring, punching, peel of mould and method, in deburring, punching, and the separation of part about having accomplished.
The technical scheme that the present invention solves the problems of the technologies described above is following: a kind of automobile panel deburring, punching, peel of mould, comprise upper die and lower die, and patrix comprises upper bolster, deburring die plate insert, piercing punch, middle cutoff tool, goes up binder body, guiding attaching parts; Counterdie comprises that die shoe, trimming and piercing die separate punch-die and insert, descend material returned body, material returned body guide pad, material returned body stop screw, spring, push rod, push rod cushion block, waste material box; In patrix, deburring die plate insert, piercing punch and middle cutoff tool are fixed on the upper bolster, and last binder body is attached on the upper bolster; Patrix cutter piece comprises above-mentioned deburring die plate insert, piercing punch, middle cutoff tool; In counterdie, trimming and piercing die separates insert (middle for separating cutting edge, periphery is trimming edge), waste material box etc. of punch-die and is installed on the die shoe; Following material returned body is attached on the die shoe through material returned body stop screw and spring; Material returned body stop screw and spring control is moving of material returned body down, and following material returned body is an insert structure, and die shoe is provided with backing plate; Backing plate is provided with slug breaker, passes slug breaker and backing plate in the middle of the following material returned body.
Further, on the following material returned body material returned body cover plate is housed.
The technical scheme that the present invention solves the problems of the technologies described above is following on the other hand: a kind of automobile panel deburring, punching, separation method may further comprise the steps:
Product is put among the upper die and lower die, carried out matched moulds with counterdie with patrix is descending;
Product is carried out deburring, punching simultaneously, separate and cut off the waste material at product middle part simultaneously through the slug breaker that in the middle of counterdie, is provided with;
With the up die sinking of patrix; Following material returned body on the die shoe upwards ejects the waste material that trimming and piercing die separates separated cut-out in the separation cutting edge of punch-die in the middle of inserting; The product week leftover bits and pieces of material that forms after above-mentioned deburring is accomplished separately skids off from the counterdie fore-and-aft direction naturally, and the punched scrap that forms after above-mentioned punching is accomplished falls into the waste material box naturally.
Beneficial effect
The invention has the beneficial effects as follows, in trimming and piercing die, the separation of part about having accomplished; After deburring, punching, separation; Following material returned body ejects the cut-out waste material of centre, and the separation waste material of rear and front end separately skids off naturally, and the waste material after being convenient to separate is got rid of smoothly.
