Description

A kind of progressive die
Technical field
The present invention relates to a kind of technical field of structures of diel, especially a kind of progressive die.
Background technology
In the prior art, the increased compound cutting die on progressive die, the generally upper mould of the structure of its compound cutting die, under Mould, a punch-pin and a cavity plate are formed, so as to realize punching work when needing to be punched complex and product that volume is larger Make, therefore general use after the completion of device to hole punching, is then transported in another mould in a step mould and is punched out, falls again Material, such working method cause the accuracy of manufacture of product relatively low, larger error are easily produced when realigning benchmark so that Yield rate and operating efficiency are greatly lowered, therefore can not meet the requirement for manufacturing product.
Therefore using the punching process that compound die is added in progressive die, die length is shortened, the right side meets consumer product It is required that.
The content of the invention
The invention aims to the one kind for solving the deficiency of above-mentioned technology and designing to meet product manufacturing requirement, enters one The yield rate of step lifting product manufacturing and a kind of progressive die of operating efficiency.
A kind of progressive die designed by the present invention, including die shoe backing plate, fix successively from right to left on die shoe backing plate Have porous blanking die for being punched porous articles successively and for punching, the compound cutting die of blanking, compound cutting die by Include upper bolster, blanking die fixed plate, blanking die, stripper and the lower mould fixed with die shoe backing plate under up to successively Seat, the top of upper bolster are provided with groove, have push pedal in groove, the bottom surface of push pedal is fixed with transmission rod;Blanking die fixed plate Depressed part and blanking die through hole Corresponding matching after form die cavity, built-in be provided with of die cavity re-packs;The bottom of transmission rod is successively With re-packing fixation after upper bolster and blanking die fixed plate;The bottom surface of upper bolster is fixed with endoporus punch retainer, re-packs Nib in there is endoporus punch-pin, endoporus punch retainer is fixed after blanking die fixed plate with endoporus punch-pin;Stripper Nib it is built-in be provided with blanking punch, be provided with endoporus cavity plate built in the nib of blanking punch, the nib of endoporus cavity plate respectively with it is interior The nib Corresponding matching of hole punch-pin and die shoe, die shoe backing plate are provided with the discharge opening with the nib Corresponding matching of die shoe; Spring one is provided between stripper and die shoe.
The course of work of said structure:The station of mould first is the porous blanking die for going out multiple holes on flitch successively, Second station is is punched out simultaneously, the compound cutting die of blanking, wherein by the porous blanking die of the first station in material strip After going out multi-hole position, blanking is punched out in the compound cutting die that the material strip feeding second station for having multi-hole position will be rushed, in punching During blanking, the punching mechanism of punch press pushes when promoting the upper bolster to move down into up to bottom dead centre, by waste material after the downward punching press of endoporus punch-pin Separated from material strip, waste material exports from the discharge opening of lower mould;Blanking punch rushes product in the presence of blanking die pushes Enter in the through hole of the blanking die of upper mould and stay in through hole.When upper mould up moves to top dead-centre in the presence of spring one, Punch press is passed to power by die shank, push pedal, transmission rod re-pack on product is released out of blanking die through hole, while conveyer belt Stretch into mould and the product fallen down is caught and sent out.
The beneficial effect of said structure:Press work can be completed by being worked by a secondary mould on punch press, so as to be lifted The yield rate and operating efficiency of product manufacturing, meet product manufacturing requirement.Further with safe operation, it is easy to automate Production, high velocity ram machine can be used to produce, it is possible to reduce punch press site area, the transport and warehouse for reducing semi-finished product take.
Further preferably, compound cutting die from top to bottom includes cope plate, locating template, material strip location-plate, lower mould successively Plate and lower mold fixed plate, array from left to right on cope plate and be fixed with more than one piece and be respectively used to stamp mark hole, mounting hole, each Kind flute profile, air vent, correcting nail, the piercing punch of fabrication hole, the bottom of more than one piece piercing punch sequentially passes through locating template With material strip location-plate, and multiple nibs in lower template respectively with each piercing punch correspond match, lower mold fixed plate it is more Individual nib corresponds with multiple nibs of lower template connect respectively.Its structure pushes six punchings after cope plate by punching mechanism Hole punch-pin punching downwards simultaneously, is realized with this and goes out the hole of various patterns in material strip one by one successively or go out various patterns simultaneously Hole;It has safe operation, is easy to automated production, high velocity ram machine can be used to produce, it is possible to reduce punch press site area, The transport and warehouse for reducing semi-finished product take.
Further preferably, spring two is set between push pedal and the inner bottom surface of groove.Its structure causes push pedal can be certainly after moving down The function that row resets, and it is simple in construction, installation and removal are more convenient.
Further preferably, the inner bottom surface of groove and the top surface of die shoe are equipped with counterbore, and spring one is located at die shoe In counterbore, spring two is located in the counterbore of groove inner bottom surface.The counterbore of its structure is realized and spring one and spring two is positioned Fixation, lift performance.
Further preferably, die shank is fixed with the top of push pedal.The die shank of its structure is realized and is connected with punching mechanism more just Victory, realize Quick Release or packaged function.
Further preferably, the bottom of endoporus cavity plate is provided with endoporus cavity plate backing plate, and endoporus cavity plate backing plate is fixed on die shoe In nib.Endoporus cavity plate backing plate in its structure has the function that to carry out rigid support to endoporus cavity plate so that mould is long-term It recessed will not be damaged using lower die shoe, lift service life.
Further preferably, compound cutting die length 900mm, porous blanking die length 800mm.Its structure, which solves, to be punched A secondary progressive die is further added by punching blanking die during the product of complexity, causes the increased technical problem of mold station;Due to needing The product to be punched is complicated, volume is larger, and the maximum die-filling length of punch press of the industrial motor iron core of blanking structure complexity is 2000mm, it is 2400mm or so when being further added by a step progressive die overall length length on porous blanking die, so as to pass through said structure The progressive die length that is bonded of compound cutting die and porous blanking die control in the range of 2000mm punch press length.
