The technology comprises the steps that a copper rod (1) is released from a rod material pretreatment device (7); the straight copper rod enters a heating device (2); a hearth comprising an induction heating coil is heated by the heating device (2); a heating temperature is measured by a temperature measurement sensor (5), and dynamically compared with a set temperature; heating power is adjusted by an electrical control system to ensure that the heating temperature of the rod is within a set temperature range; and the heated copper rod passes through an oxidation prevention device (3), enters a continuous extrusion machine (4), becomes a required product through the continuous extrusion machine (4), and enters an aftertreatment device (6) to be cooled and coiled into a disc-shaped product. The oxidation prevention device (3) is an oxidation prevention protecting pipe; a pipe opening at one end of the pipe is connected with the heating device (2); and a pipe opening at the other end of the pipe is connected with a feed port of the continuous extrusion machine (4). The plasticity of the billet is improved effectively, and the deformation resistance of the billet is reduced.
Description
Technical field
The present invention relates to a kind of pressing method, relate in particular to a kind of copper alloy made-up belt continuously extruding and molding equipment and manufacturing process thereof.
Background technology
The tradition continuous squeezing method is that the bar blank of cold conditions is directly sent into continuous extruder, its advantage is that the bar material does not need heating, can save energy resource consumption, shortcoming is, relatively poor and the very high material of resistance of deformation adopts cold bar material for some plasticity, because the material plasticity index is excessively low, blank generation underbead crack in the meeting pinch process, and can cause a large amount of energy wastes and the enhancing of labour intensity.This shows that traditional continuous squeezing method production equipment falls behind, complex technical process, the production cycle is longer.
Summary of the invention
The present invention is directed to defects, purpose is to provide a kind of bar material preheating continuous squeezing method, Effective Raise the plasticity of blank, reduced its resistance of deformation, saved multi-pass ground annealing process, greatly reduce energy consumption and processing charges.
Technical scheme of the present invention: comprise the pretreatment unit (7), heater (2), oxidation (3), continuous extruder (4), sensor for measuring temperature (5), the after-treatment device (6) that connect successively.
Continous way extruder (4) is by shelves material piece (8), cavity parent (9), mould (10), cavity gland (11), trip bolt (12) forms, shelves material pieces (8) are an individual part, and shelves material pieces (8) are embedded in the groove of cavity parent (9), and mould (10) is installed in the cavity mold (9), cavity gland (11) is fixed on mould in the cavity parent (9), and fixes by trip bolt (12).
Copper alloy made-up belt continuously extruding and molding preparation technology, carry out according to following steps:
First copper bar (1) is emitted through bar material pretreatment unit (7); for straight copper bar enters heater (2); heater (2) heats for the burner hearth that comprises load coil; measure heating-up temperature by sensor for measuring temperature (5); and carry out dynamic contrast with the temperature of setting; regulate heating power by electric control system; guarantee that the heating-up temperature of bar material is in the temperature range of setting; the copper bar through the heating after through oxidation (3); oxidation (3) is for preventing the oxidation protection pipe; the one end mouth of pipe connects heater (2); other end mouth of pipe continuous extruder (4) charging aperture; enter continuous extruder (4), become in the required product after-treatment device (6) by continuous extruder (4), cool off and be curled into the product of dish
Advantage of the present invention is: device structure of the present invention is simple, increased the on-line heating device on traditional continuously extruded basis, for fear of oxidation, increase oxidation after the blank heating, can effectively prevent the bar material surface oxidation that blank heating causes.The sensor of measuring temperature is arranged in heater, be associated by the rotating speed with continuous extruder, can be controlled in the whole extrusion process, the heating-up temperature of blank bar is constant.Adopt simultaneously the combined type cavity body structure, the intensity and the shelves material piece that efficiently solve cavity damage the problem of changing.
The present invention is simple in structure, has saved multi-pass ground annealing process, greatly reduces energy consumption and processing charges, has created significantly economic benefit and social benefit.
