Abstract
The invention discloses a replaceable mold which uses indirect extrusion and drawing to mold crystallizer blank copper pipe. Wherein, said replaceable mold comprises: an upper supporting board and a upper punch body mounted on the machine head; a chassis, a mould sheath, a compression ring, a compression plate, a discharge board, a material underlay and a material underlay ring mounted on the operation board. The invention is characterized in that: a screw is arranged at the lower end of upper punch body to be connected with the screw thread of upper punch pin via double-ended binding bolt; a cavity die is mounted inside the taper hole of mould sheath, while the circumference of said cavity die has spiral groove which contains electrical heating element and the heating element is connected to external circuit via the taper hole of mould sheath; the bottom of material underlay has a screw hole connected with material beating rod of tail block; and the top of upper punch body is connected with upper supporting board key. Said mold has better adjustable ability, which can realize the replacement between punch pin and cavity die, improve the final forging environment of blank copper pipe, and improve the producing efficiency and the rate of finished products, while it can apply the corporation for processing single multi-variety copper pipe.
Description
Technical field
The present invention relates to the metal extruding, relate in particular to reverse extruding and drawing moulding continuous cast mold mould and method with the blank copper pipe.
Background technology
Manufacturing of crystallizer copper pipe be unable to do without the blank copper pipe.Because single and mini-batch production characteristics fierce and that crystallizer copper pipe is produced are competed in market, be reflected in that just to develop into the situation that in short supply and price tend towards superiority in the blank supply of raw material with increasing intensity daily.In order to adapt to the needs of production, guarantee raw-material timely supply, reduce cost of raw, manufacturer is forced to adopt the self-control blank, from the measure of roughcast copper pipe, with the demand of the single and mini-batch production that satisfies market.From the roughcast copper pipe, traditional handicraft all adopts the way of reverse extruding and drawing moulding.Mainly there are two key issues in this method, at first is the copper pipe at different specification size, must design the loose tool tool one by one, makes the kind of mould and quantity more and more many, and time and effort consuming is changed in the adjustment of mould, has caused very big waste.Secondly, the initial temperature of mould is very low, especially when environment temperature is very low when, the temperature effect of mould the final forging temperature of copper base, when not finishing finish-forging, just be forced to stop breaking, have to melt down by secondary, row is processed again.In order to adapt to the demand of multi-varieties and small-batch, overcome the drawback that must make a large amount of loose tool tools, further improve the tire Mould design, make it reach purpose general, that exchange, just become one of industry question of common concern.
Summary of the invention
Proposition of the present invention is intended to develop targetedly the confession ability of being badly in need of the blank copper pipe, satisfies the possible period of want or need in market, designed a kind of adopt the interchangeable loose tool tool of reverse extruding and drawing moulding and by recessed broad-mouthed receptacle for holding liquid to the manufacture method of blank copper pipe.
Technical solution of the present invention is achieved in that
A kind of reverse extruding and the drawing moulding crystallizer interchangeable mould and the method for blank copper pipe, wherein said interchangeable mould comprises mounting plate, the upper punch body that is contained in the head of a bed and is contained in base, die sleeve, pressure ring, pressing plate, stripper, backing strap and backing strap ring on the workbench, it is characterized in that screw being arranged, be threaded with upper punch by the double end connecting bolt in the lower end of upper punch body; In the taper hole of die sleeve die is arranged, die connects with die sleeve is movable; On the outer surface of die helicla flute is arranged, the mid-discharge heating element heater of groove, heating element heater is connected with external circuit by the through hole of die sleeve; The top of die sleeve has bolt that stripper and pressing plate are fixed on the die sleeve; At the bottom of backing strap suit backing strap ring, screw is arranged at backing strap bottom, is connected with knockout rod on being contained in tailstock; Upper punch body top then is connected with the mounting plate key.
A kind of described reverse extruding of claim 1 and drawing moulding crystallizer of utilizing pushes method with drawing with the interchangeable mould of blank copper pipe, comprise by the design scale get the raw materials ready, on hydraulic press installation mold and with the step of blank heating, it is characterized in that also comprising:
(1) at first connects electrical heating elements, with the step of 100～200 ℃ of die preheatings;
(2) blank of heating is packed into rapidly in the die, backward extrusion becomes the step of broad-mouthed receptacle for holding liquid to mobile punch to blank;
(3) with the recessed broad-mouthed receptacle for holding liquid demoulding of moulding and the step of water-cooled;
(4) with above-mentioned recessed broad-mouthed receptacle for holding liquid acid Xian, be processed into the step that band leaks the recessed broad-mouthed receptacle for holding liquid of end shape then;
(5) adopt size mandril and outer shroud mould that recessed broad-mouthed receptacle for holding liquid is carried out the step that drawing promptly gets required blank copper pipe according to designing requirement.
Compared with the prior art, the invention has the advantages that the technology that adopts oppositely extruding and drawing moulding has solved the raw material supply problem of blank copper pipe, utilize prior oil pressure machine and simple a spot of technological equipment, with the copper base by being squeezed into recessed broad-mouthed receptacle for holding liquid the blank copper pipe that arrives, simple and reliable process, production link is few, and cost reduces relatively, can satisfy the demand that single and mini-batch production is produced.
