Description

Technical Field

[0001] The utility model relates to the technical field of titanium-clad copper production, and specifically comprises an automated production line for titanium-clad copper rods. Background Art

[0002] Titanium-clad copper composite rods mainly utilize the excellent corrosion resistance of the titanium coating and the good electrical conductivity of the copper core. They can be used as a conductor that carries large currents under strong corrosive media conditions. In the electrolytic production of non-ferrous metals, the protection of the copper matrix by the coating metal prevents the corrosion of the copper conductor, ensures the uniformity of the current density, and improves the quality of the electrolytic products. At the same time, the conductor is free of cleaning and maintenance, eliminating the pollution of the electrolyte caused by the corrosion of the copper conductor. Due to the excellent characteristics of titanium-clad copper rods, it brings about the improvement of product quality, the improvement of production efficiency, the reduction of energy consumption and the reduction of labor intensity, etc., making it widely used in chlor-alkali, electric power, electroplating, electrolysis, hydrometallurgy, petroleum, nuclear industry and other fields.

[0003] The main production methods of titanium-clad copper composite rods include drawing, extrusion + drawing, explosive welding + rolling, brazing, etc. The traditional drawing composite method is to first put the copper rod and the titanium tube together, and then use a die to reduce the diameter of the rod and draw it to achieve a close fit between the two. It is characterized by a simple process, but the problems are: the metal is in a stress state of "two pressures and one pull" during the processing, resulting in a small deformation in a single pass, low interface bonding strength of the composite rod, and low degree of automation. The extrusion method is to heat a large-diameter composite material composed of two metals to a certain temperature, and then extrude it through a die space. Under high pressure, it is accompanied by huge deformation, and a deep metallurgical bond is produced at the titanium-copper interface. Generally, a wider composite wave and composite belt will be formed, and the composite strength is high. The problems are: the product interface is uneven, the technical difficulty is high, and the surface quality of the pipe is poor. The explosive welding method is to first load the copper rod into the titanium tube and evenly distribute the explosives outside the titanium tube, and rely on the explosion of the explosives to generate the pressure required to connect the metals, so that the two overlapping surfaces can be solid-phase welded. Its characteristics are high temperature and high pressure during forming, and the composite rod has high bonding strength, but the problems are: the operating environment is unfriendly, the risk is high, and the amount of explosives is difficult to control. The characteristic of the brazing method is that the heating temperature of the brazing process is relatively low, so the deformation of the weldment after brazing is small, and it is easy to ensure the dimensional accuracy of the weldment. At the same time, the influence on the organization and performance of the weldment base material is relatively small. The disadvantages are: the heat resistance of the brazed joint is relatively poor, the joint strength is relatively low, and the requirements for surface cleaning and weldment assembly quality during brazing are relatively high. In addition, the above-mentioned processes have problems such as high energy consumption, high production cost, poor geometric accuracy, low yield rate, and low degree of automation.

[0004] Therefore, the utility model provides an automated production line for titanium-clad copper rods with a simple structure and a high degree of automation. Utility Model Content

The copper rod is manually inserted into the titanium tube 41 with a sharp end, and then the tip is inserted into the drawing die 53. The second control console 52 controls the drawing cylinder 62 to push the drawing trolley 55 close to the tip, and the jaws 56 clamp the tip. The drawing cylinder 62 drags the titanium tube 41 with a sharp end through the drawing die 53. At the same time, the tube is squeezed by the drawing die 53 and compressed into a specified shape, thereby making a titanium-clad copper composite rod 72. The second tube-pushing cylinder 54 pushes the titanium-clad copper composite rod 72 to the finished product stacking rack area 7 of the work section. The second hydraulic station 61 is also a prior art. The numbers in the figure are: hydraulic cabinet 613, hydraulic motor 612, second oil pipe 611 and other necessary parts are not marked.

[0040] The finished product stacking rack area 7 includes a finished product stacking bracket 71 and a titanium-clad copper composite rod 72 .

[0041] The copper in the titanium-clad copper composite rod 72 is T2 copper, and the titanium is TA1 or TA2; the wall thickness of the titanium tube 12 is 1 to 2 mm, and the titanium-clad copper rod 72 is round or square, and the diameter of the round copper is The long diameter of the square is 30-70mm, and the short diameter is 20-50mm.

[0042] It should be noted that in an automated production line for titanium-clad copper rods, the incoming titanium tubes 12 are neatly placed on the loading rack 1 during operation, and the ejection cylinder 14 of the loading rack 11 pushes the titanium tubes 12 one by one onto the tube support rack 21; after the guide rail mechanism 2 receives the signal from the first photoelectric sensor, the tube transport mechanism rises, and the second tube clamping mechanism 26 clamps the titanium tube 12, and at the same time drives the titanium tube 12 to move toward the first tube clamping mechanism 25. After moving to the set position, the first tube clamping mechanism 25 clamps the titanium tube 12 again, and at this time, one end of the titanium tube 12 is already on the extrusion base 317 of the hydraulic extruder. The first control console 33 sends a signal, and the hydraulic station 32 supporting the hydraulic extruder 31 starts to work, driving the 1# oil cylinder 313 and the 2# oil cylinders 314 on both sides, pushing the # extrusion module 315 and the 2# extrusion module 316, and rolling one end of the titanium tube 12 into a heterogeneous tip shape. After the sharpening is completed, the first tube clamping mechanism 25 is released, and the second tube clamping mechanism 26 returns to the set position. Then the second tube clamping mechanism 26 releases the titanium tube 41 with a sharp end, and the tube transport mechanism sinks and returns to its original position. The tube pushing cylinder 13 pushes the titanium tube 41 with a sharp end to the tube waiting rack 4. At this time, the tube waiting rack 4 is manually inserted with a copper rod into the titanium tube 41 with a sharp end, and the tip of the titanium tube 41 with a sharp end is pushed through the drawing mold 53. The worker operates the second control console 52, and the drawing trolley 55 moves close to the drawing die 53 under the drive of the drawing cylinder 62. The second control console 52 receives the proximity sensor signal at the drawing die 53, and the jaws 56 close to clamp the heterogeneous tip of the titanium tube 41 with one end pointed. Then the drawing trolley 55 starts to move away from the drawing die 53, and the undeformed part of the titanium tube 41 with one end pointed passes through the drawing die 53 under the traction of the drawing trolley 55. The titanium tube 41 with one end pointed is deformed inwardly due to external compression during the process of passing through the drawing die 53. At the same time, there is a copper rod inside as a support, so that the deformed titanium tube is close to the copper rod. When the sensor at the drawing die 53 senses that the drawing of the titanium tube 41 is completed, the signal is transmitted to the second control console 52. At this time, the jaws 56 of the drawing trolley 55 are loosened, no longer clamping the tip, and returning to the original position. At the same time, the second tube pushing cylinder 54 pushes the titanium-clad copper rod 72 to the finished product stacking bracket 71 of the work section, and the above process is repeated for batch production. After all the incoming titanium-clad copper composite rods 72 are drawn and produced, the finished product stacking rack 7 is manually removed and each titanium-clad copper rod is cut to the required length. Compared with the current mainstream titanium-clad copper rod production process, this cold drawing composite process is suitable for thin-walled titanium tubes 1-2mm. The thinner the titanium tube wall, the better the composite effect, which saves the amount of titanium and greatly reduces the cost of raw materials. On the other hand, this system equipment is relatively simple, without heavy and heavily polluting equipment, saving equipment costs, simple installation, and minimizing the impact on the environment.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
