Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a method for taking out the rods made of copper-clad aluminum row cables after heat treatment, and to solve the problem of taking out high-temperature copper-clad aluminum rods from the kiln. Oxidation phenomenon, once oxidation occurs, subsequent grinding and polishing must be carried out to remove the oxide layer after the copper-clad aluminum bar is made, which greatly increases the production cost, so how to solve the problem of no oxidation on the surface of the copper tube after heat treatment of the copper-clad aluminum bar The problem has been restricting the development of the industry

Embodiment 1

[0039] Such as Figure 1-8 Shown, the present invention 1, make the method for taking out after the bar stock heat treatment of copper-clad aluminum row cable, comprise steps:

[0040] Step 1. A multi-layer copper-clad aluminum bar rack 2 is provided in the nitrogen-protected heating box furnace 1, and a plurality of bar stock stations 3 are arranged on each layer of copper-clad aluminum bar stock rack 1, and each bar stock station 3 corresponds to place a copper-clad aluminum rod 4; the nitrogen-protected heating box furnace 1 is provided with a lifting furnace door 5, and when the lifting furnace door 5 is closed, each copper-clad aluminum rod 4 corresponds to a lifting furnace door 5 is provided with a bar material take-out port 6, and each bar stock take-out port 6 is provided with a sealing plug 7;

[0041] Step 2, a guide rail 9 is provided on the ground corresponding to the furnace door 8 of the nitrogen-protected heating box furnace 1, and an electric cart 10 is provi...

Embodiment 2

[0054] Such as Figure 1-8As shown, the present invention is made into a copper-clad aluminum row cable bar material heat treatment method for taking out, the copper-clad aluminum bar rack 2 includes a side support frame 33, a horizontal support frame 34 and a vertical support frame 35, two side support frames 33 are connected by a plurality of cross braces 34, and a plurality of cross braces 34 are connected in series through more than one vertical brace 35. A protruding butt joint 36 is provided on the top surface of the side support frame 33, and on the bottom surface of the side support frame 33 A concave butt joint 37 is provided. The concave butt joint 37 of each layer of copper-clad aluminum bar stock rack 2 is butted on the raised butt joint 36 of the lower layer of copper-clad aluminum bar stock rack 2 to be superimposed.

[0055] A plurality of bar stock stations 3 are arranged on the cross brace 34, and the bar stock stations 3 on each cross brace 34 are correspond...

Embodiment 3

[0059] Such as Figure 1-8 As shown, the present invention is made into a copper-clad aluminum row cable rod stock heat treatment method for taking out, the fetching pipe 28 is a square pipe, and the fetching pipe 28 can be a square pipe or a round pipe, and the square pipe is better to use. The lower side of the front end of the retrieving pipe 28 is provided with a wedge-shaped surface. When the retrieving pipe 28 enters and exits the furnace from the bar stock outlet 6, the copper-clad aluminum bar 4 is basically in the center of the retrieving pipe 28, so when the retrieving Pipe 28 stretches out in the hearth constantly, and the front end of material fetching pipe 28 will be against on the cross brace 34 of copper-clad aluminum rod rack 2, by being provided with wedge-shaped surface under the front end of taking material pipe 28, so just can The pick tube 28 is slid into the cross brace 34 .

[0060] The method for taking out the bar material of the copper-clad aluminum ...

Abstract

The invention discloses a method for taking out a heat-treated bar for manufacturing a copper-clad aluminum busbar cable. After the copper-clad aluminum bar placed on a copper-clad aluminum bar frameis subjected to heat treatment by a nitrogen protection heating box furnace, a trolley driving motor is controlled to drive an electric trolley to move to a lifting furnace door on a guide rail, a lead screw driving motor is controlled to drive a bidirectional lead screw to rotate to adjust the height of an electric material taking support frame, the height of a material taking pipe on the electric material taking support frame is made to be aligned with the height of a row of copper-clad aluminum bars needing to be taken out, nitrogen is introduced into the material taking pipe, a sealing plug is opened, a traction support frame is controlled to drive the material taking pipe to be inserted into a bar taking-out port, the material taking pipe continues to be inserted, the copper-clad aluminum bars are guided into the material taking pipe, the material taking pipe is pulled out by the traction support frame, and the copper-clad aluminum bars are cooled under nitrogen protection.

Description

technical field [0001] The invention relates to the technical field of cable processing equipment and industrial kiln equipment, in particular to a method for taking out a bar material made of a copper-clad aluminum row cable after heat treatment. Background technique [0002] In order to save costs and resources, copper-clad aluminum row cables with basically the same performance are often used in the market instead of copper bars. Copper-clad aluminum row cables are made by inserting aluminum rods into copper tubes, and then drawing and rolling. [0003] In order to further improve the various performances of the copper-clad aluminum row cable, in the production process of the copper-clad aluminum row cable 54, the copper-clad aluminum bar is heat-treated before drawing and rolling, which is convenient for subsequent drawing and rolling. At the same time, a fusion layer is formed between the copper tube and the aluminum rod, which effectively improves the conductivity of t...
