Abstract

A continuous grading mold mechanism is formed by an upper mold base, a lower mold base, guiding columns, guiding sleeves, a screw, a punch retainer, an unloading base plate, a spring, a guide pin, a piercing punch, a bending mold plate insert, a limiting column, a floating block, a spacer, a pushing rod, a gasket, inner guiding columns, inner guiding sleeves, a pushing block, a stock supporting plate, an adjusting rod, a sleeve and a limiting sleeve. A mold is provided with eight inner and outer guiding columns and the guiding sleeves to guide, the guiding columns and the guiding sleeves are all arranged to be ball guiding, limiting is carried out by means of the limiting column, the guiding columns and the limiting sleeve are fixed through an adhesive mode, error accumulation of component machining is reduced, mold guiding positioning precision is improved, and due to the fact that the mold is stamped at a high speed, working components of the mold are rapidly abraded. Therefore, main working components are designed to be small inserts. The mold is high in automatic degree, long in service life, capable of producing other products after the main components of the mold are replaced, and environment-friendly and energy-saving; and the mold plays a great role in protecting safety of workers due to the fact that outer guiding columns are arranged in production of the mold.

Description

A kind of continuous progressive die mechanism

Technical field

The present invention relates to the metal cool-press mould, is a kind of continuous progressive die mechanism.

Background technology

At present, on the metal cool-press mold mechanism, there are formal dress mould, anti-mould, bending mould, perforating die, notch die, the reducing die adorned in the mechanism that adopts, because they all are to adopt high speed stamping, the wearing and tearing of mould groundwork part are very fast, the inconvenience that repairs a die, and insert in the design of stripper upper end punch guiding, its intensity, hardness, abrasion resistance are not reached the punching press requirement, cause mould to be scrapped.Simultaneously in order to guarantee the die precision, therefore on die plate insert, all be provided with voussoir, this is to the Mould Machining manufacturing, install, debugging brings very big inconvenience, adjustment mode and the spacing adjustment of adjusting mould adjustment power cause the product size deviation, cause simultaneously towards waste material the time, easily cause upset herein, in order to improve the punching precision of part, therefore when designing mould, 2II position, 1I position is designed in one is inserted, insert and adopt the inlaid type structure, the stripper insert design is got about discharging plate hight 0.03mm, therefore just cause the mould structure complexity, mould is made inconvenient, cause mould very easily to collide with cutting edge at punching course simultaneously, cause die point to break.In order to overcome the defective of above-mentioned mold mechanism, I give production line design and manufacturing experience for many years, and the spy provides following a kind of mold mechanism to solve this difficult problem.

Summary of the invention

The present invention provides a kind of continuous progressive die mechanism, it is achieved in that after mould is installed on the forcing press during punching press, mould inner guiding post, guide pin bushing, outer guiding post, guide pin bushing lead, pilot pin inserts the correcting hole correcting strip on the band material, and stripper contacts binder with the buoyant piece.Patrix continues to compress strip fully down to the recessed template of stripper, blanking punch, and forming terrace die is started working, and patrix continues to come downwards to closure state then, finishes stamping-out, forming process.During die sinking, opposite when moving just with matched moulds, each parts are returned to reset condition, and strip pushes a step pitch forward under the effect of autoloader, prepare next working cycles.A kind of continuous progressive die mechanism, solved when high speed stamping, mould groundwork parts depreciation is very fast, inconvenient problem repairs a die, solved on discharging, to design to insert punch has been led, its intensity, hardness, abrasion resistance does not reach the punching press requirement, the problem that causes mould to be scrapped, solved in order to guarantee the die precision, at die plate insert voussoir has been set, to the Mould Machining manufacturing, install, debugging brings very big inconvenience, cause the problem of product size deviation, solved the mould structure complexity, cutting edge and mold work part are collided in punching course, the difficult problem of mold damage cutting edge.A kind of continuous progressive die mechanism is characterized in that: guide pin bushing (2) and upper bolster (1) immovable fitting, convex mould pad (3) and punch retainer (5) are torn curved punch (34) open with limited post (31), push rod (38), discharging screw (39) matched in clearance, discharging screw (39) runs through upper bolster (1), convex mould pad (3), punch retainer (5), discharging backing plate (6), behind the stripper (7), be communicated with die block (12) again, push rod (16) is installed in die shoe (14) and upward and with die backing plate (13) gap is slidingly matched, guide pillar (4) be installed in that die shoe (14) is gone up and with stripper (7), discharging backing plate (6), punch retainer (5), convex mould pad (3), guide pin bushing (2) glade plane space cooperates, inner guiding post (25) and upper bolster (1), convex mould pad (3), punch retainer (5), discharging backing plate (6), stripper (7), die block (12), die backing plate (13), die shoe (14) glade plane space cooperates, and limited block (26) is fastened on respectively on die shoe (14) and the upper bolster (1).

The specific embodiment:

A kind of continuous progressive die mechanism, this mould adopts inside and outside 8 guide pillars, guide pin bushing to lead, all be set to accurate ball guiding, adopt limited post to carry out spacing, and guide pillar and stop collar all adopt gluing mode to fix, reduce the accumulation of part's machining errors, improve guiding and the positioning accuracy of mould.Thruster mechanism is adopted in location on band material width, use strip near stock guide one side feeding, on feed direction, because strip advances apart from having only between the 0.5-0.8mm, adopt the side edge fine positioning to add the pilot pin fine positioning behind the correcting hole, and then just with 3 pilot pin correcting band material, can reduce accumulated error like this, improve the positioning accuracy of band material.The course of work is during the mould punching press: during matched moulds, and interior outer guiding post, guide pin bushing guiding, pilot pin inserts the correcting hole correcting strip on the band material, and stripper contacts binder with the buoyant piece.Patrix continues to compress strip fully down to stripper and concave template, blanking punch, and forming terrace die is started working, and patrix continues to come downwards to closure state then, finishes stamping process.During die sinking, move just on the contrary with matched moulds, each parts reset to reset condition.The band material pushes a step pitch forward under the effect of autoloader, carry out next program.
