Abstract

The invention relates to a compound die used for a double-slot-hole workpiece. The compound die comprises an upper die base and a lower die base which are installed oppositely, two punches are arranged at the bottom of the upper die base in a spaced mode, a concave die is arranged on the lower die base, two through holes are formed in the positions, under the two punches, of the concave die, and the two punches and guide sleeves are fixed to the upper die base through epoxy resin; each punch comprises a guide part and a working part, wherein the guide part is arranged below the working part, the guide part is a conical part, and an alloy ring is arranged on the periphery of the working front end face of the working part and made of a low-nickel-chromium-molybdenum alloy. Double holes are formed through once punching, the production efficiency is improved, the center distance between the two holes is ensured, and the machining quality of the workpiece is ensured; the guide sleeves and the two punches are fixed through the epoxy resin, machining of the die is greatly simplified, and the manufacturing cost of the die is reduced; due to the structural design of the punches, the punching service life of the punches is prolonged, and the accuracy and the quality of the punched holes are improved.

Description

A kind of two elongated hole workpiece compound die
Technical field
The present invention relates to a kind of compound die, be specifically related to a kind of two elongated hole workpiece compound die.
Background technology
Two elongated hole workpiece is part conventional in ribbon conveyer, and in its production process, punching technology is processed at twice, this production method not only cost is high, efficiency is low and waste time and energy, and its holes centre-to-centre spacing error is also very large, is difficult to ensure crudy, in addition, in industry, the pierce punch of common use is in use because rubbing with steel part always, and cause wearing and tearing, the size causing the hole processed is changing always, precision less than guarantee, the situation of wear out failure also occurs repeatedly.During the hole that if desired requirement on machining accuracy is higher, just need frequently to change drift, the time that wastes, with artificial, reduces production efficiency.
Summary of the invention
The present invention seeks to provide a kind of ensure crudy and two elongated hole workpiece compound dies of enhancing productivity to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution used in the present invention is: a kind of two elongated hole workpiece compound die, and comprise the upper bolster, the die shoe that are mounted opposite, described upper bolster bottom interval is provided with two groups of drifts; Described die shoe is provided with die, and this die is provided with two groups of through holes immediately below described two groups of drifts; Described two groups of drifts and guide pin bushing are fixed on upper bolster respectively by epoxy resin; Described drift comprises guide part and operate portions; Described guide part is arranged on the below of operate portions; Described guide part is Tapered Cup, and the periphery in described operate portions working front edge face is provided with alloy hoop; Described alloy hoop selects low nickel-chrome-molybdenum alloy to make.
Improve further as the present invention, bottom described upper bolster, be respectively equipped with guide pin bushing, guide rod with both sides, described die shoe top, described guide rod is inserted in guide pin bushing.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The two elongated hole workpiece compound die of one of the present invention program, adopt one time punching molded diplopore, not only increase production efficiency and ensure that holes centre-to-centre spacing, thus guarantee workpiece processing quality, epoxy resin is adopted to fix guide pin bushing and two drifts, the processing of mould is simplified greatly, reduces the cost of manufacture of mould; The structural design of drift, not only extends the service life of punch but also improves punching hole precision and quality.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of pair of elongated hole workpiece compound die of the present invention;
Wherein: 1, upper bolster; 2, die shoe; 3, drift; 4, die; 5, through hole; 6, guide pin bushing; 7, guide rod; 8, epoxy resin; 9, guide part; 10, operate portions; 11, alloy hoop.
detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is the two elongated hole workpiece compound die of one of the present invention, and comprise the upper bolster 1, the die shoe 2 that are mounted opposite, described upper bolster 1 bottom interval is provided with two groups of drifts 3; Described die shoe 2 is provided with die 4, and this die 4 is provided with two groups of through holes 5 immediately below described two groups of drifts 3; Described two groups of drifts 3 are fixed on upper bolster 1 with guide pin bushing 6 respectively by epoxy resin 8; Described drift 3 comprises guide part 9 and operate portions 10; Described guide part 9 is arranged on the below of operate portions 10; Described guide part 9 is Tapered Cup, and the periphery in described operate portions 10 working front edge face is provided with alloy hoop 11; Described alloy hoop 11 selects low nickel-chrome-molybdenum alloy to make; Adopt epoxy resin 8 to fix guide pin bushing 6 and two drifts 3, the processing of mould is simplified greatly, reduces the cost of manufacture of mould; In drift 3 punching course, first be that guide part 9 is exerted pressure punching in advance, then operate portions 10 carries out formal punching, even if, guide part 9 is subject to a little wearing and tearing, also do not affect crudy, the design of alloy hoop 11 improves the wearability of drift working face and hardness and toughness, not only extends the service life of punch but also improves punching hole precision and quality.
Bottom described upper bolster, be respectively equipped with guide pin bushing 6, guide rod 7 with both sides, described die shoe top, described guide rod 6 is inserted in guide pin bushing 7, is matched by guide rod 7 and guide pin bushing 6, patrix is fallen more accurate.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
