Description
Technical field
The present invention relates to a kind of automobile covering trimming, punching, peel of mould and method, belong to cold punching technology field.
Background technology
Mould design and manufacture 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 pursuing production.Under normal circumstances, for automobile panel, after drawing and forming, need to complete follow-up deburring in two steps, punching and separation, had a strong impact on operating efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of automobile covering trimming, punching, peel of mould and method, while deburring, punching, completes the separation of left and right part.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of automobile covering trimming, punching, peel of mould, comprises upper die and lower die, and patrix comprises upper bolster, deburring die plate insert, piercing punch, middle cutoff tool, upper material pressing body, guiding attaching parts, counterdie comprises die shoe, trimming and piercing die is separated punch-die insert, lower material returned body, material returned body guide pad, material returned body stop screw, spring, lower push rod, push rod cushion block, waste material box, in patrix, deburring die plate insert, piercing punch and middle cutoff tool are fixed on upper bolster, and upper material pressing body is attached on upper bolster, and patrix cutter block comprises above-mentioned deburring die plate insert, piercing punch, middle cutoff tool, in counterdie, trimming and piercing die is separated punch-die insert (middle for being separated cutting edge, periphery is trimming edge), waste material box etc. is arranged on die shoe, lower material returned body is attached on die shoe by material returned body stop screw and spring, material returned body stop screw and spring control the movement of lower material returned body, lower material returned body is insert structure, die shoe is provided with backing plate, backing plate is provided with slug breaker, through slug breaker and backing plate in the middle of lower material returned body.
Further, material returned body cover plate is equipped with lower material returned body.
The technical scheme that the present invention solves the problems of the technologies described above is as follows on the other hand: a kind of automobile covering trimming, punching, separation method, comprise the following steps:
Product is put among upper die and lower die, carry out matched moulds by descending for patrix with counterdie;
Carry out deburring, punching to product, the slug breaker simultaneously by arranging in the middle of counterdie is separated and cuts off the waste material in the middle part of product simultaneously;
By up for patrix die sinking, the waste material that trimming and piercing die is separated separated cut-out in the separation cutting edge in the middle of punch-die insert by the lower material returned body on die shoe upwards ejects, the product week leftover bits and pieces of material of formation after above-mentioned deburring completes separately skids off naturally from counterdie fore-and-aft direction, and after above-mentioned punching completes, the punched scrap of formation falls into waste material box naturally.
Beneficial effect
The invention has the beneficial effects as follows, while trimming and piercing die, complete the separation of left and right part, after deburring, punching, separation, the cut-out waste material of centre ejects by lower material returned body, and the separation waste material of rear and front end separately skids off naturally, is convenient to the waste material after being separated and gets rid of smoothly.

Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in the figure, 1. counterdie trimming and piercing die is separated punch-die insert 104 periphery is trimming edge, and middle for being separated cutting edge, centre is separated cutting edge place, sets up middle slug breaker 104-13.2., when the descending matched moulds of patrix, carry out the separation cut of deburring, punching and centre simultaneously.3. after deburring, patrix is up, and after die sinking, lower material returned body 206 ejects by lower push rod, and middle separation cut waste material, by jack-up, is conveniently taken.The waste material of periphery skids off at fore-and-aft direction, and punched scrap falls into waste material box 202.4. the slug breaker in the middle of is placed on backing plate 207, and this backing plate is connected with die shoe.5. descend material returned body to be led by the material returned body guide pad 209 being separated cutting edge and fore-and-aft direction, because slug breaker installed by needs, lower material returned body needs install material returned body cover plate 206-1 additional.6. during assembling, first lower material returned body is put into, then waste knife backing plate is connected with die shoe, then separation cutting edge and cut-out waste knife are installed on backing plate, finally material returned body cover plate is connected with lower material returned body body.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
