Description
Technical field
The utility model belongs to the shaping jig technical field of extruding metal more particularly to a kind of combination of continuous extrusion of copper strip
Mold.
Background technology
Continuous extrusion of copper strip forming technique is one kind in extrusion forming technology, and continuous extrusion of copper strip forming technique has work
The advantages that good product quality that the simple and environmentally-friendly energy saving, production of skill obtains, thus industry favor is received, use is more next in the industry
It is more extensive, it is used by numerous copper material processing enterprises.
Continuous extrusion of copper strip molding die is the core equipment component in continuous extrusion of copper strip forming technique, is squeezed using continuous
When pressure technology extrudes copper bar, stripping operation can be carried out after extruding completion, i.e., beaten using hammer, the modes such as jack will be in die hole
Clout at mould discharging mouth to feed inlet direction eject.It is a kind of special to be used when extruding certain special copper bars
Die for continuously extruding, the calibrating strap of the die for continuously extruding is in intermediate and feed inlet, discharge port band taper.In extrusion process
In, such mold bears high temperature and pressure, and the high temperature and pressure bigger born at feed inlet, thus clout easily attach into
Material mouth, causes to demould extremely difficult, and discharge port is with taper, it is impossible to directly be ejected using tool, otherwise the more push up the more tight, must adopt
It is time-consuming and laborious with the residual copper removed the methods of drilling and milling, wire cutting in die hole, it even can damage die-face sometimes and cause
Mold is scrapped.
Utility model content
For the purpose of this utility model in a kind of continuous extrusion of copper strip assembling die of offer, copper material can be quick after extruding completion
Demoulding can effectively avoid burn failure while improving efficiency.
In order to achieve the above object, the base case of the utility model is：A kind of continuous extrusion of copper strip assembling die, including
Upper die and lower die, upper mold or lower die are equipped with boss, and the groove for engaging with boss is provided in upper mold or lower die；The lower die
The calibrating strap and discharge port being sequentially communicated inside are provided with, the feed inlet that can be connected with calibrating strap, discharge port and charging are provided in upper mold
Mouth is disposed as truncated cone-shaped；The taper of the discharge port is set as 8-12 degree, the smaller one end of discharge port face area and sizing
Band connection；The taper of the feed inlet is set as 6-10 degree, feed inlet face area smaller one end when upper die and lower die engage
With sizing band connection.
The operation principle of this base case is：When needing continuous extrusion of copper strip being molded, boss is fastened on groove,
Upper die and lower die is made to be fixed as an entirety, then the mold after combination are mounted in die cavity, you can start to extrude copper material.It squeezes
After the completion of system, mold is taken out from die cavity, part clout can be remained in the feed inlet, discharge port and calibrating strap of mold, squeezed
After system completion cooling, due to expanding with heat and contract with cold, the clout sectional dimension remained in calibrating strap can be slightly less than calibrating strap.Stripping operation
When, active force is applied to lower die, lower die is made to be detached with upper mold, then removing clout using modes such as sawing, millings stretches out upper mold
Upper mold also can quickly deviate from after the redundance of feed inlet.
The advantageous effect of this base case is：
The 1st, boss and groove be set, during work using boss and groove engaging upper mold and lower die can be fixed as one it is whole
Body, upper die and lower die separation, dislocation, ensure the quality processed when avoiding extruding copper material.
2nd, feed inlet, discharge port are disposed as with tapered, when clearing up clout, by clout to upper mold feed inlet end face
The smaller one end of area applies active force, you can easily ejects clout, facilitates removing clout.
3rd, mold is set as upper die and lower die, feed inlet is located at upper mold, and calibrating strap and discharge port are located at lower die, have extruded
Work cooling after, using the principle expanded with heat and contract with cold, the sectional dimension of clout can be slightly less than calibrating strap, can make easily at this time lower die with
Clout detaches.Also part clout remains in upper mold, and the redundance for stretching out the smaller one end of feed inlet face area is cut off,
Then external force is applied to the clout for being located at feed inlet end face smaller one end of area, clout is ejected into upper mold.Using this combination
Mold, copper material can realize fast demoulding after extruding completion, improve efficiency, and effectively mold can be avoided to be damaged.
Further, the upper mold is H13 steel upper molds, and the lower die is high temperature alloy or ceramal lower die.Extruding copper
During material, stress is concentrated mainly on upper mold, and upper mold is easily damaged, and needs to be replaced frequently, intensity, heat resistance of H13 steel etc.
Preferably, and price inexpensively, upper mold is made using H13 steel, effectively reduces production cost.Shape, the size of product are main
It is controlled by lower die, the quality of lower die has product a significant impact, and high temperature alloy or ceramal have excellent elevated temperature strength, good
The comprehensive performances such as good anti-oxidant and hot corrosion resistance, good fatigue behaviour, are made of high temperature alloy or ceramal
Lower die, the quality of lower die is guaranteed, so as to ensure the quality for the product produced.
Further, the upper mold is equipped with boss, and lower die is provided with the groove engaged with boss.Boss, groove are set, pass through card
Conjunction can make upper and lower mould be fixed as an entirety, very convenient.
Further, the boss is opposite with feed inlet.The position of boss is set as opposite with feed inlet, structure is the simplest
It is single, and stress is more concentrated at the feed inlet of upper mold, can ensure that upper and lower mould will not misplace in process of production.
Further, the lower die is equipped with boss, and upper mold is provided with the groove engaged with boss.Boss, groove are set, pass through card
Conjunction can make upper and lower mould be fixed as an entirety, very convenient.
Further, the boss is opposite with calibrating strap.The position of boss is set as opposite with calibrating strap, structure is the simplest
It is single, and stress is more concentrated at the feed inlet of upper mold, can ensure that upper and lower mould will not misplace in process of production.
