Abstract
This utility model belongs to a metal die in the non-ferrous metal processing, which especially relates to a die for pipe block plate extrusion molding; this die is the tower shape, including front end, middle part and rear part, the front end and middle part is the projected ring, and the rear part is square or ring. This die can utilize most of part of metal of existent casting ingot central part, which enhances finished product rate and reduces production cost and acquires more dense internal material. The eccentric ratio is reduced from 8 to 12 percent to 2 to 7 percent, and the evenness of wall thickness is increased by over 50 percent. This metal die is widely used for production of copper, aluminum as well as copper and aluminum alloy pipe, which will play more roles in large size pipe.
Description
Technical field
The utility model belongs to a kind of metal die in the non-ferrous metal processing, relates in particular to a kind of copper, aluminium and copper, aluminium alloy pipe closure plate extrusion modling mould of being used for.
Background technology
At present, be widely used in crystallizer, the employed copper in water flowing trunk line aspect, aluminium and the copper of building trade, the aluminium alloy pipe of large-scale iron and steel enterprise, adopt the slubbing operation of extruding mostly, in large size copper, aluminum pipe extruding, again based on horizontal extruding as processing.Development along with domestic and international various manufacturings, to copper, the wall thickness accuracy of aluminum pipe requires to improve day by day, because the uniformity of wall thickness is directly connected to copper, aluminum pipe service life, even and horizontal extruding is under equipment precision meets the requirements of situation, because deadweight influence that large-scale extrusion axis itself is brought and the gap between ingot casting and the extrusion axis, copper in addition, the elevated temperature strength of aluminium is lower usually, at metal still during the underfill recipient, because the extrusion position of front end is a free end, according to law of minimum resistance, nib has been flowed out in high temperature ingot casting front portion, and is can't filling complete.Usually it is circumferentially inhomogeneous when causing metal flow to go out nib that top is gapped, tubing is eccentric serious, and tubing head especially, the stub bar that pecker passes when perforation can reduce the lumber recovery of product (tubing specification, diameter and radius-thickness ratio are big more, the perforation stub bar is heavy more, and influence is just remarkable more).
The extruding program of the horizontal extruding of tubing at present is generally: ingot casting is sent into recipient, this moment the front end station be extrusion position → extrusion axis forward filling → extrusion axis be back to desired location bore a hole → extrusion axis pushes forward.The uniformity coefficient of tube wall thickness is the important technology index of copper, aluminium and copper, aluminium alloy pipe, the extruding program is usually as the slubbing operation, it is the inhomogeneity basis of decision tube wall thickness, especially for big specification tubing, present existing extruding program and mould promptly can't improve the tube wall thickness uniformity, so can't satisfy the requirement that copper, aluminium and copper, aluminium alloy pipe improve day by day by rolling can not the stretching by multi-pass again.
Summary of the invention
In order to overcome above-mentioned prior art defective, the purpose of this utility model provides a kind of finer and close closure plate extrusion modling mould of tube wall thickness precision, lumber recovery and tubing inner materials that improves.The closure plate extruding is innovated conventional extruded, its effect is to make copper, aluminium and copper, aluminium alloy pipe carry out sufficient filling before flow of articles goes out nib, promptly can eliminate the gap between ingot casting and the recipient, thereby the metal circumferential flow is even in the realization extrusion process, obtain the tubing of wall thickness good evenness, meet the need of market, and can significantly reduce by how much waste material ratios of product, improve lumber recovery, can obtain finer and close inner materials again simultaneously.
The purpose of this utility model is achieved by following technical proposals:
A kind of pipe blocking plate extrusion modling mould, this mould is a tower, and it comprises that front end, middle part, rear portion consist of one, and front end, middle part are round for what protrude, and the rear portion is a square or round; Described mould is in extrusion process, be matching used with recipient, extrusion axis, pecker and the extruding pad of extruder, promptly in extrusion process, increase a closure plate mould station and one closure plate mould station is replaced with the extrusion position program, mould and recipient are close to during filling, anterior free end changes blind end into when being about to present traditional filling, be replaced with extrusion position subsequently again, just have free-ended mould.Adopt in the extrusion process: ingot casting is sent into recipient, this moment the front end station be closure plate station → extrusion axis forward filling → extrusion axis be back to the position be set bore a hole → the front end station is replaced with extrusion position → extrusion axis and pushes forward.
Ingot casting is sent into recipient, and this moment, the front end station was a closure plate mould station: the closure plate extrusion molding dies is that closure plate is fixed by being placed on the closure plate seat on the horizontal sliding form frame of extruder, and moves by horizontal movable cylinder control; Closure plate mould top is provided with screw and is convenient to place and change.The closure plate extrusion molding dies be be installed in the recipient on the extruder and be installed in extrusion axis on the extruder rear cross beam and pecker and extruding pad matching used, mould and recipient are close to during use; Toe angle and recipient port angular be complementary angle or be a kind of extrusion molding dies that is used on plane each other; Closure plate mould front end enters recipient or is close to recipient in the work, combines closely with recipient.
Beneficial effect
Change blind end into owing to anterior free end during filling, can more complete filling, and also because the sealing of front end, make and caused the secondary filling in the perforation procedure, compare with at present traditional extruding, can make the metal in ingot casting centre no longer directly flow out nib simultaneously and become waste material how much, but most ofly reflux, and promote the rear portion metal and move backward with respect to pecker; The distortion of this metal under HTHP can substantially improve the original cast sturcture of metal inside, and makes the metal of original ingot casting central part obtain most of the utilization, improves lumber recovery, reduces production costs, and can obtain finer and close inner materials again.Eccentricity is reduced to 2～7% by common 8～12%, and the wall thickness uniformity improves more than 50%.This pipe blocking plate extrusion modling mould can be widely used in copper, aluminium and copper, aluminium alloy pipe production, and is especially more meaningful aspect big specification tubing.
