Abstract

The utility model relates to a novel forge hot piece side cut compound die that punches a hole, including upper die base, die holder, cut off die and guide pin bushing are fixed on the upper die base, and the guide pillar cooperates and fixes on the die holder with the guide pin bushing, and the drift subassembly passes through the drift holder to be fixed on the upper die base, still includes dish spring hold -down mechanism, dish spring hold -down mechanism passes through core bar and the upper and lower sliding connection of upper die base, effectively compresses tightly forge hot piece through dish spring pretightning force at the drift subassembly when the forge hot piece contacts and breaks away from. The utility model has the advantages of the control forging warp, improves production efficiency, reduces production manufacturing cost.

Description

A kind of Novel hot punching forgings trimming compound die

Technical field

This utility model relates to a kind of punching trimming compound die, particularly relates to a kind of hot forging punching trimming compound die.

Background technology

Forge hot is processed during punching, trimming, is affected by trimming, punching shearing force, deformation easily occurs, at present It is that nitrogen cylinder compresses, due to Chain Link hot forging punching most suitable as Chain Link punching forgings trimming compound die thrust device Trimming completes in the event of high temperatures, and nitrogen cylinder seals to be affected by high temperature, and the life-span is shorter, and nitrogen cylinder is expensive. Thus add cost of goods manufactured, make the competitiveness of product in market receive large effect.

Utility model content

The purpose of this utility model, it is simply that for solving the problem that prior art exists, and devise and provide a kind of disc spring The track link rail hot forging punching compound trimming die of structure, this device can once complete punching, trimming and correcting process, Improve production efficiency, reduce forging manufacturing cost.

The technical scheme that technical problem is provided is:

A kind of Novel hot punching forgings trimming compound die, is fixed on upper mold including upper bolster, die shoe, edger and guide pin bushing On seat, guide pillar coordinates with guide pin bushing and is fixed on die shoe, and punch-head assembly is fixed on upper bolster by master block, also wraps Including disc spring pressing mechanism, described disc spring pressing mechanism is slided up and down with upper bolster by core bar and is connected, at punch-head assembly in forge hot Hot forging is effectively compressed by disc spring pretightning force when part contact and disengaging.

Described disc spring pressing mechanism includes de-material support, and described de-material support slides up and down with guide pin bushing and core bar and is connected, The upper and lower two ends of spring connect de-material support and upper bolster respectively.

Described Novel hot punching forgings trimming compound die also includes stripper, and described stripper passes through spring and die shoe Floating connection.

Described core bar and disc spring disc spring quantity are 2n, n >=1.

This utility model has the beneficial effects that: disc spring pressing mechanism is by applying one to forging in trimming, punch process Fixed thrust, can eliminate the impact of shearing force, so that forging is not deformed or deformation extent controls in claimed range, Reach the effect after correction, improve production efficiency.Nitrogen cylinder can be substituted in Chain Link hot forging blanking process compress, reduce Manufacturing cost, has good economic benefit.

Detailed description of the invention

Referring to the drawings, in this utility model, edger 3 is fixed on upper bolster 12, and upper male mould 2 is fixed on de-material support 8 On, de-material support 8 is connected with upper bolster 12 by core bar 13；Upper bolster 12 is at least installed two core bars 13, disc spring 14 Being connected to upper bolster 12 by core bar 13 expect, on support 8, to form disc spring pressing mechanism with de-, described core bar 13 number is 2n, Wherein n >=1, described drift I 5, drift II 6, drift III 7 are fixed on upper bolster 12 by master block 9；Under described convex Mould 1 is fixed on die shoe 11；Described stripper 4, by spring 10 and die shoe 11 floating connection, ejects for discharging.

In actual applications, being placed on by hot forging on lower punch 1, part of the upper die moves downward with lathe slide block, upper male mould 2 First contact with hot forging；Moving further downward with part of the upper die, disc spring 14 is compressed, and pressure is by de-material support 8 and upper Punch 2 is applied on forging, after forging is compacted, and the drift I 5, drift II 6, the drift III 7 that are contained on upper bolster 12 and cut Limit mould 3 starts punching, cuts gross weight and the overlap of forging products, die-cut completes back punching head I 5, drift II 6, drift III 7 and edger 3 Moving upwardly together with upper bolster 12 and lathe slide block, in motor process, upper male mould 2 keeps enough pressures all the time to forging products Power, until after drift I 5, drift II 6, drift III 7 and edger 3 leave forging, upper male mould 2 just departs from forging, now discharging Overlap is released under spring 10 acts on and is departed from lower punch 1, before and after gross weight falls into die shoe 11 centre after punching already by plate 4 In through hole, whole die-cut operation terminates.
