Description

Technical Field

[0001] The invention relates to the technical field of copper straight tube rolling processing, in particular to a rolling device used for processing smooth copper straight tube materials. Background Art

[0002] The rolling process of copper straight tubes is a common method of heating heavy copper straight tubes and processing them into copper straight tubes through a rolling process. During the rough rolling process, the copper straight tubes undergo continuous rolling deformation, gradually changing from heavy copper straight tubes to thinner copper straight tubes. Rough rolling usually requires the use of large rolling mills, such as two-roll mills, four-roll mills, etc., for multiple rolling passes.

[0003] During the rolling process of copper straight tubes on the tube rolling mill, the high temperature of the inner wall of the copper tube reacts with the oxygen in the air to easily form a copper oxide layer. The existing rolling mill is not convenient for processing the copper oxide layer on the inner wall of the steel tube, resulting in the oxide layer not only affecting the surface quality of the copper tube, but also possibly having an adverse effect on subsequent processing. For example, the oxide layer will reduce the adhesion between the copper tube and the welding material or the coating, affecting the welding strength and corrosion resistance.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting up the tube wall processing mechanism, when the tube rolling mill is rolling the copper straight tube, the rotating grinding rod can grind the copper oxide layer on the inner wall of the copper straight tube. The removal of the copper oxide layer can not only improve the surface quality of the copper tube, but also effectively reduce the problems of roughness and corrosion of the inner wall of the copper tube caused by the residual copper oxide layer, so that the inner wall of the copper tube can maintain good finish and good physical properties, which not only improves the production efficiency, but also effectively improves the quality of the copper tube, so that it can meet higher precision and performance requirements in subsequent processing;

[0014] 2. By setting up a transmission mechanism, the grinding rod can be driven to move back and forth and swing back and forth while the grinding rod is performing turnover grinding. Through reciprocating motion and swinging, the grinding rod can have a wider contact with the inner wall of the copper tube, increase the efficiency of removing the copper oxide layer, and reduce the uneven local wear that may be caused by a single grinding method, which can reduce the grinding time, further improve the removal efficiency of the copper oxide layer on the inner wall of the copper straight tube, and significantly improve the surface quality of the copper tube;

[0015] 3. By setting up an oxide layer collection tube, while the rotating sleeve drives the tube wall processing mechanism to perform grinding, it will also drive the fan blades to rotate and collect the oxide layer, which can collect the oxide layer debris generated during the grinding process to the greatest extent, ensuring that the entire grinding process is more efficient and clean. At the same time, by setting up a clamping block, it is convenient to quickly disassemble and assemble the oxide layer collection tube during cleaning, saving time and reducing the downtime of the production line, ensuring the continuity and efficiency of production.

[0027] like Figure 3As shown, an air guide hole 201 is provided through the mandrel 2, a motor 202 is fixedly provided on the inner wall of one end of the mandrel 2 close to the connecting frame 4, the output end of the motor 202 extends through the inner wall of the mandrel 2 to the outside and is fixedly provided with a driving wheel 203, and an annular rack A204 is fixedly provided on the end surface of the mandrel 2, and the annular rack A204 is meshed with the driving wheel 702 for transmission. The driving wheel 203 connected to the motor 202 is driven to rotate, so that the driving wheel 203 can drive the rotating sleeve 5 connected to the driven wheel 501 to rotate, so that the rotating sleeve 5 can drive the pipe wall processing mechanism 8 on the fixed frame 6 to rotate.

[0028] like Figure 4 As shown, a conical sleeve 401 is fixedly provided at one end of the connecting frame 4 away from the core rod 2, a clamping sleeve 402 is fixedly provided at the conical sleeve 401, a transmission rod 403 is rotatably connected in the connecting frame 4, and a transmission wheel 404 is fixedly provided at one end of the transmission rod 403 located in the connecting frame 4. The conical sleeve 401 can effectively block the collected oxide layer slag.

[0029] like Figure 5 As shown, a driven wheel 501 is fixedly provided at one end of the rotating sleeve 5 close to the core rod 2, and the driven wheel 501 is meshed with the driving wheel 203 for transmission. An annular rack B502 is fixedly provided on the inner wall of the other end of the rotating sleeve 5, and the annular rack B502 is meshed with the transmission wheel 404 for transmission.

[0030] By arranging a tube wall processing mechanism 8 on the core rod 2, the copper oxide layer appearing on the inner wall of the copper straight tube 3 can be polished when the copper straight tube 3 is rolled. The removal of the copper oxide layer can not only improve the surface quality of the copper tube, but also effectively reduce the problems of roughness and corrosion of the inner wall of the copper tube caused by the residual copper oxide layer, so that the inner wall of the copper tube can maintain good smoothness and good physical properties, which not only improves the production efficiency, but also effectively improves the quality of the copper tube, so that it can meet higher precision and performance requirements in subsequent processing.

[0031] The movable seat 801 is slidably matched with an arc-shaped slider 806, and the arc-shaped slider 806 is fixedly provided with an arc-shaped rack 807, which is meshed with the adjusting wheel 803 for transmission. A polishing rod 808 is fixedly provided at one end of the arc-shaped slider 806, and the polishing rod 808 is frictionally contacted with the inner wall of the copper straight tube 3.

[0032] like Figure 8As shown, the inner wall of the oxide layer collection tube 9 is fixedly provided with an inclined filter plate 901, and the filter plate 901 is rotatably connected with a transmission sleeve 902, and the inner wall of the transmission sleeve 902 is slidably matched with the outer wall of the transmission rod 403, and the other end of the transmission sleeve 902 is fixedly provided with a fan blade 903. The inclined filter plate 901 allows the oxide layer slag to flow along the surface of the filter plate 901 under the action of gravity. This process increases the contact time and area between the oxide layer slag and the filter plate 901, so that the filter plate 901 has more opportunities to intercept the impurity particles therein, thereby significantly improving the filtering effect. When the oxide layer slag flows through the inclined filter plate 901, larger impurity particles are not easy to accumulate at the filter hole for a long time. Under the combined action of gravity and airflow, these impurities will slide down along the surface of the filter plate 901, reducing the risk of the filter hole being blocked, ensuring the continuous and stable progress of the filtering process, and maintaining a high filtering efficiency. The rotating rotating sleeve 5 will drive the transmission wheel 404 to rotate through the connected annular rack B502, so that the transmission wheel 404 drives the connected transmission rod 403 to rotate, and at this time the transmission rod 403 drives the fan blade 903 connected to the transmission sleeve 902 to rotate.

[0033] A clamping block 904 is slidably fitted through the inner wall of one side of the oxide layer collecting tube 9 near the clamping sleeve 402. The clamping block 904 is movably plugged with the inner wall of the clamping sleeve 402. An inclined surface is provided at one end of the clamping block 904. A spring 905 is fixedly provided on the clamping block 904. The other end of the spring 905 is fixedly connected to the inner wall of the oxide layer collecting tube 9. An inclined surface is provided at one end of the clamping block 904 to facilitate insertion into the clamping sleeve 402. Press the clamping block 904 and pull the oxide layer collecting tube 9 outward, so that the clamping block 904 can be removed from the clamping sleeve 402.

[0034] Working principle: When a thick-walled copper straight tube 3 needs to be rolled into a thin-walled copper straight tube 3, the heated thick-walled copper straight tube 3 is firstly put on the mandrel 2, and the thick-walled copper straight tube 3 is rolled by the tube rolling machine 1;

[0035] Then, the motor 202 is used to drive the connected driving wheel 203 to rotate, so that the driving wheel 203 can drive the rotating sleeve 5 connected to the driven wheel 501 to rotate, so that the rotating sleeve 5 can drive the pipe wall processing mechanism 8 on the fixed frame 6 to rotate;

[0036] At this time, the annular driving wheel 702 will mesh with the annular rack A204, thereby driving the driving wheel 702 to rotate, so that the driving wheel 702 can drive the connected bending rod 701 to rotate, so that the bending rod 701 can drive the push-pull frame 703 to move back and forth, thereby driving the moving seat 801 connected to the push-pull frame 703 to move back and forth, so that the polishing rod 808 moves back and forth to process the oxide layer on the inner wall of the copper straight tube 3;

[0037] At the same time, when the movable seat 801 moves back and forth, under the action of the fixed guide column 805, the rotating shaft 802 connected with the spiral groove 804 will be driven to rotate, so that the rotating shaft 802 drives the adjusting wheel 803 to rotate forward and reversely. At this time, the adjusting wheel 803 drives the arc-shaped slider 806 connected to the arc-shaped rack 807 to slide back and forth, thereby driving the connected polishing rod 808 to slide back and forth, further improving the efficiency of oxide layer treatment;

[0038] At the same time, the rotating sleeve 5 will drive the transmission wheel 404 to rotate through the connected annular rack B502, so that the transmission wheel 404 drives the connected transmission rod 403 to rotate. At this time, the transmission rod 403 will drive the fan blade 903 connected to the transmission sleeve 902 to rotate, and inject external air through the air guide hole 201, so that the flowing air can collect the polished copper oxide layer into the oxide layer collection tube 9, and filter it through the filter plate 901. Then, after the copper straight tube 3 is rolled, the clamping block 904 is pressed and the oxide layer collection tube 9 is pulled outward, so that the clamping block 904 can be removed from the clamping sleeve 402, so that the collected copper oxide layer can be cleaned conveniently.
