Abstract
The utility model discloses an extrusion device for a copper and copper alloy pipe. The extrusion device comprises an extrusion cylinder, an extrusion stem, an extrusion plug, a pressure pad conveyor and an ingot conveyor. The extrusion device is characterized by comprising two pressure pads, wherein one pressure pad is larger than the other pressure pad; the large pressure pad is arranged above the small pressure pad; the diameter of the large pressure pad is equivalent to the inner diameter of the extrusion cylinder; and the middle part of the extrusion cylinder is provided with a heater. Superlarge and superthick copper and copper alloy pipe products produced by the device has the advantage that the surface quality of the extrusion products is high; the extrusion products have large specifications and sizes; by adopting the extrusion device, the superlong and superlarge copper and copper alloy pipe products which are scarce in the production market and have high product added value are easily produced; few extrusion residues are generated in the extrusion process and the extrusion process has high pass percent; and the extrusion energy consumption of an extrusion method adopting the extrusion device is about 30 percent lower than the extrusion energy consumption of a positive extrusion method.
Description
Technical field
The utility model belongs to technical field of nonferrous metal processing, relates in particular to the pressurizing unit of a kind of copper and copper-alloy pipe-material.
Background technology
The extruding of available technology adopting forward double-acting extruding machine super large, ultra thick copper and copper-alloy pipe-material need to be equipped with high large-scale special extruder of cost and expensive extruding frock, and production cost is high.Reverse single action extruder can only push excellent wire product, and large-scale reverse double-acting extruding machine cost is very high, and the restriction of be squeezed mold shaft intensity and size, and the tubing goods specification that can push is restricted.
The utility model content
The purpose of the utility model is exactly the problem that exists to prior art, and the pressurizing unit of a kind of copper and copper-alloy pipe-material is provided.
Above-mentioned purpose realizes through following proposal:
The pressurizing unit of a kind of copper and copper-alloy pipe-material; It comprises recipient, pressure ram, extruding plug, dummy block transveyer and ingot casting transporter; It is characterized in that said pressurizing unit comprises two dummy blocks, one of them is bigger than another; The top of the said less dummy block that bigger dummy block is installed, and the diameter of bigger dummy block is suitable with the recipient interior diameter.
Pressurizing unit according to above-mentioned is characterized in that, at said recipient middle part heater is housed.
The beneficial effect of the utility model: super large, ultra thick copper and copper alloy tube section product that this device is produced, it is higher to have a product surface quality of extruding; Extruded product specification, size are big, are easy to production market is rare, added value of product is high overlength, super large copper and copper alloy tube section product; Extrusion process is pressed surplus few, and the extrusion process lumber recovery is higher; Compare extruding energy consumption low about 30% with the forward extrusion method.
Description of drawings
Fig. 1 is the structural representation of the utility model;
The process sketch map that Fig. 2-Figure 10 is to use the pressurizing unit of the utility model to push.
The specific embodiment
Referring to Fig. 1; The copper of the utility model and the pressurizing unit of copper-alloy pipe-material comprise recipient 2, pressure ram 1, extruding plug 3, dummy block transveyer 5 and ingot casting transporter 7; Pressurizing unit comprises two dummy blocks 4 and 6; The top of the said less dummy block 6 that bigger dummy block 4 is installed, and the diameter of bigger dummy block 4 is suitable with recipient 2 interior diameters.At recipient 2 middle parts the heater (not shown) is housed, the effect of heater is that recipient is carried out preheating, and preheat temperature is between 350 ℃-450 ℃.
The concrete course of work is following:
Before carrying out extrusion process, ingot casting is carried out railway carriage, the recipient inwall is cleared up.Ingot casting is heated to the extrusion process temperature, when heating, strengthens the protection against oxidation of ingot casting.About 2 hours before the extrusion production operation, recipient, pressure ram, dummy block are warmed up to 350-450 ℃.Carry out the extrusion production operation then, its operation process is following:
(1) ingot casting transporter 7 is transported to the material loading station of recipient with ingot casting, and dummy block transveyer 5 is transported to dummy block between pressure ram and the ingot casting, and pressure ram 1 pushes recipient successively with ingot casting and dummy block, accomplishes to ingot action on the recipient.See Fig. 2, Fig. 3.
(2) press on the extruder master cylinder, pressure ram promotes dummy block ingot casting 8 is pushed, fills, ingot casting 8 is full of and recipient 2 and plug 3 between the gap.See Fig. 4.
(3) pressure ram 1 drives a dummy block 4 and withdraws from recipient 2, takes off dummy block 4.See Fig. 5.
(4) pressure ram 1 promotes the ingot casting of 6 pairs of piers of secondary extrusion pad after thick and carries out secondary and oppositely push.See Fig. 6.
(5) secondary extrusion end, plug separate with recipient.See Fig. 7.
(6) utilize expanding with heat and contract with cold of pipe, pipe and extrusion axis are withdrawed from from recipient.See Fig. 8.
(7) take off pipe and secondary extrusion pad from extrusion axis, and carry out the recipient cleaning.See Fig. 9.
(8) plug return, first-class secondary extrusion pad and dummy block are prepared to push next time.See Figure 10.
Claims (2)
1. the pressurizing unit of copper and copper-alloy pipe-material; It comprises recipient, pressure ram, extruding plug, dummy block transveyer and ingot casting transporter; It is characterized in that said pressurizing unit comprises two dummy blocks, one of them is bigger than another; The top of the said less dummy block that bigger dummy block is installed, and the diameter of bigger dummy block is suitable with the recipient interior diameter.
2. pressurizing unit according to claim 1 is characterized in that, at said recipient middle part heater is housed.
