Problems solved by technology

[0003] In view of the above problems, the present invention proposes a method for producing copper rods, which solves the problem that the existing equipment directly cools the capstan with cooling water, and the high-temperature copper rod enters the low-temperature capstan. The temperature difference between the two is too large, and the copper rod shrinks rapidly. , it is easy to produce stress and affect the final quality; in addition, if the cooling effect of the winch is poor, the high-temperature copper rod in the winch will also enter the air, and the copper rod will shrink rapidly due to the large temperature difference, resulting in the problem of stress

Embodiment 1

[0030] Such as figure 1 Shown, the present invention discloses a kind of method of producing copper rod, comprises the following steps:

[0031] 1) Copper melting process: melting the copper plate into molten copper;

[0032] 2) Casting rod process: casting the molten copper on the surface of the core rod to generate a cast rod; the casting rod process includes copper rod drawing operation, peeling operation and dip coating operation; the copper rod drawing operation is: using copper rod The wire drawing device draws the copper rod into a core rod, and transfers the heat from one side of the wire drawing furnace to the capstan through the circulating helium, and at the same time uses cooling oil to cool the capstan; the peeling operation is: the core after the wire drawing is cooled The rod is subjected to peeling treatment; the dip coating operation is: coating molten copper on the surface of the peeled copper rod.

[0033] 3) Hot-rolling process: hot-rolling the cooled cas...

Embodiment 2

[0036] Such as figure 2 As shown, the present invention also discloses a copper rod wire drawing device, comprising: a wire drawing furnace 1 and a capstan 2, a helium circulation system 3 passing through the connection between the wire drawing furnace and the capstan; There is a cooling oil circulation system 4; wherein the helium circulation system includes a helium heat pipe 5 installed at the junction of the end of the copper rod drawing furnace and the capstan and passing through the two, and helium is passed inside the helium heat pipe; The outside of the helium heat pipe is covered with a first sleeve 6; the cooling oil circulation system includes a conical coil 7 and an annular oil storage cylinder 8, and the oil storage cylinder passes through a liquid outlet pipe 14 and a liquid return pipe 15 is connected to the conical coil; the oil storage cylinder is in the shape of a truncated cone, and the outer diameter of the oil storage cylinder increases gradually from the...

Abstract

The invention discloses a method for producing a copper rod. The method comprises the following steps of 1) in the copper melting working procedure, melting a copper plate into molten copper; 2) in the casting rod working procedure, casting the molten copper on the surface of a core rod to generate a casting rod; 3) in the hot rolling working procedure, carrying out hot rolling treatment on the cooled casting rod to generate a copper rod; and 4) in the winding working procedure, winding the copper rod into a ring. The casting rod working procedure comprises copper rod wiredrawing operation, wherein the copper rod is drawn to become a core rod by adopting the copper rod wiredrawing device. Heat on one side of a wiredrawing furnace is transferred into a winch through circulating helium gas,and meanwhile, the winch is cooled by using cooling oil. The method solves the problems that in the prior art, cooling water is used for directly cooling a winch, a high-temperature copper rod entersthe winch, the temperature difference between the copper rod and the winch is too large, the copper rod shrinks rapidly, stress is easy to generate, and the final quality is influenced.

Description

technical field [0001] The invention relates to the field of copper rod production, in particular to a method for producing copper rods and a copper rod wire drawing device. Background technique [0002] In the production process of preparing copper rods by the dip coating method, it is necessary to wire-draw and peel the copper rods to produce qualified copper rods used as seed rods in the casting rod step. The peeling device is used to remove the oxide layer on the surface of the copper rod. Because the copper rod is soft, it is difficult to achieve the required surface finish after peeling the copper rod directly. Therefore, a wire drawing machine is required to draw the copper rod before peeling to improve The surface hardness of the copper rod facilitates the completion of the peeling operation. However, due to the increase in the running speed of the wire drawing machine in recent years, a large part of the heat generated during the wire drawing process is brought to ...
