Description

Copper spare hot stamping die

Technical field

The present invention relates to the hot stamping die technical field, specifically is a kind of copper spare hot stamping die.

Background technology

A kind of copper spare that is called as the copper twin adapter is arranged at present; It is that hexagonal copper rod is raw material that the processing of this copper spare is adopted with cross section; Earlier process two joints through turner, and then punching axially connects copper rod, this processing mode is loaded down with trivial details, raw materials consumption is big, production efficiency is low; Processing is simple, raw material are economized, advantage of high production efficiency and copper spare hot stamping die has, and does not still see at present to be useful on the copper spare hot stamping die of producing said copper twin adapter.

Summary of the invention

The technical problem that the present invention will solve is that a kind of copper spare hot stamping die that is used for the production of copper twin adapter is provided.

Technical scheme of the present invention is; Copper spare hot stamping die of the present invention; It comprises die shank, cope match-plate pattern, upper die plate, upper mounted plate, rubber blanket, take off the backing strap plate, be provided with upper mold core upper mold core fixed head, lower bolster, counterdie backing plate, bottom plate, be provided with the lower die-sleeve of lower mold core; Said cope match-plate pattern, upper die plate, upper mounted plate, rubber blanket, take off backing strap plate, upper mold core fixed head and connect in regular turn from top to bottom; Said lower bolster, counterdie backing plate, bottom plate, lower die-sleeve connect from bottom to top in regular turn, and said upper mold core is provided with hexagonal hole; With punch on the said hexagonal hole sliding fit one; Last punch upper end pass take off be arranged in the upper mounted plate setting behind backing strap plate, the rubber blanket be used for said first hole of going up punch of axial limiting; Said upper end and the said first hole sliding fit; The end face of said upper end can with one pass die shank, upper die plate offsets with the lower surface that gets into the knock-pin in said first hole; The second hole sliding fit that the said knock-pin of the confession that is provided with in said knock-pin and die shank, the upper die plate passes, the said punch lower end of going up is provided with pilot hole and the first moulding hole that is used for moulding first joint from top to bottom in regular turn; Said lower mold core is provided with the second moulding hole that is used for moulding second joint, pass outside the said second moulding hole and with the coaxial counterdie positioning guide column in the second moulding hole can with said pilot hole sliding fit.

Operation principle of the present invention is, adopts copper pipe as raw material, said cope match-plate pattern, upper die plate, upper mounted plate, rubber blanket, takes off backing strap plate, upper mold core fixed head and is connected to form the part of the upper die from top to bottom in regular turn; Said lower bolster, counterdie backing plate, bottom plate, lower die-sleeve are connected to form the part of the lower die from bottom to top in regular turn, add man-hour, at first copper pipe are enclosed within to make the copper pipe bottom fall into the second moulding hole on the counterdie positioning guide column; Then, part of the upper die and part of the lower die matched moulds, counterdie positioning guide column top is slipped in the pilot hole; Copper pipe top is introduced into the first moulding hole and then promote goes up punch and moves up to top dead centre, and rubber blanket is compressed in the matched moulds process, makes to take off backing strap plate, upper mold core fixed head and in the matched moulds process, can move upward always; Matched moulds will continue after last punch stopped to move upward, and copper pipe also will be by further extruding, like this in the forming cavity that the first moulding hole, hexagonal hole, the second moulding hole, counterdie positioning guide column form; It is required form that copper pipe is extruded moulding; Be the copper twin adapter, after the die sinking, knock-pin pushes punch; Last punch is got product, thereby accomplishes product stripping.

After adopting said structure; The present invention compared with prior art; Have the following advantages: combine technique scheme and operation principle to know; The mutual cooperation of each parts can realize the drop stamping moulding of copper twin adapter, and the processing that copper spare hot stamping die had is simple, raw material are economized except that having, the advantage of high production efficiency, also have compact conformation, simple and reliable advantage.
