Abstract
Description
Technical Field
[0001] The present invention relates to a transfer mechanism after a cathode copper plate is peeled off, specifically a material supporting table frame for receiving the copper plate peeled off from the cathode plate and implementing downstream transfer. Background Art
[0002] Electrolytic copper is the copper that is free from the anode (copper) plate through the electrolyte to the cathode plate and deposited on the cathode plate in the electrolytic cell. The electrolytically deposited copper on the cathode plate is actually in the form of two copper plates connected at the bottom side. To remove it from the cathode plate, a peeling machine or a slicing machine needs to be equipped to first peel the upper edge of the copper plate on the cathode plate from the cathode plate and gradually separate the entire anode copper plate from the cathode plate. The peeled copper is received by the material supporting table frame. At this time, the V-shaped bracket 7 with an upward opening on the table frame just receives the V-shaped copper plate. Then the material supporting table frame descends to a low position, and the V-shaped copper plate is flattened by the V-shaped flipping frame that makes a transposition movement. Then the flattened copper plate is continuously transferred downstream by the downstream conveying mechanism. Then the material supporting table frame rises to a high position to wait for the peeling action of the next anode copper plate.
[0003] As Figure 1 shown, the lifting and lowering of the material supporting table frame 1 are realized by the telescopic action of a vertically arranged oil cylinder (not shown in the figure, and the support 2 in the figure is used to connect the piston rod of the oil cylinder). The material supporting table frame 1 cooperates with a vertically arranged guide rod (not shown in the figure) to limit the flat posture of the material supporting table frame 1 during lifting and lowering, that is, copper bushings (commonly known as copper tiles) 3 are arranged at the through holes at the corner parts of the material supporting table frame 1 to achieve a movable fit with the guide rod. For the convenience of maintenance, the copper bushing 3 in the prior art is composed of a split type half sleeve fit. The outside of the copper bushing 3 is also composed of a split joint type outer casing 4. Connecting bolts 5 are arranged on the side of the outer casing 4 to connect each other, and end bolts 6 are also arranged at the end of the outer casing 4 to realize the connection with the material supporting table frame 1. The problem lies in the above structural solution. When the copper bushing 3 needs to be repaired after wear, the bolts 5 and 6 on the outer casing 4 need to be removed to take out the copper bushing 3. Since the copper bushing 3 is still between the guide rod and the bushing hole on the material supporting table frame 1, it is very difficult to take out the copper sleeve 3. Moreover, what is more serious is that after the outer casing 4 radially closes to realize radial restraint on the copper bushing 3, the outer casing 4 still needs to be connected to the material supporting table frame 1 through the bolt 6. When relying on the axial bolt 6 connection, the core position of the hole of the copper bushing 3 will be eccentric interference restraint. Therefore, it is difficult to ensure that the core of the copper bushing 3 hole at the corner part of the material supporting table frame 1 is concentrically matched with each guide rod to meet the design requirements. Therefore, the smoothness and smoothness of the lifting movement of the material supporting table frame 1 cannot be guaranteed, and the wear of the copper bushing 3 is extremely common, and frequent maintenance is inevitable; moreover, due to the large eccentricity between the copper bushing and the guide rod, forced lifting and lowering may generate the action of impact bending moment, resulting in the tensile fracture of the connecting bolt 6 between the outer casing 4 and the material supporting table frame 1, and the equipment is forced to stop. Summary of the Invention
[0004] The object of the present invention is to provide a lifting platform for supporting cathode copper plates, ensuring the smoothness of the platform's lifting.
[0005] To achieve the above object, the present invention adopts the following technical solutions:
[0006] A lifting platform for supporting cathode copper plates, the supporting platform frame connected to the vertically arranged oil cylinder performs up-and-down lifting displacement movement. The copper guide sleeves are formed by enclosing Haff-type half-pipe units. The copper guide sleeves are placed in the through holes opened vertically through the supporting platform frame. The copper guide sleeves and the vertically arranged guide rods form a sliding fit. There is a flange gland at the outer end of the copper guide sleeve, and the flange gland is connected to the supporting platform frame.
[0007] In the above technical solution, the axial positioning of the copper guide sleeve is completed by the axial constraint given by the flange gland. The flange gland does not apply an external force in the radial direction to the copper guide sleeve, that is, the core position of the copper guide sleeve is not radially forcedly constrained by the flange. Therefore, the concentricity between the copper guide sleeve and the guide rod is ensured, and the concentricity of each copper guide sleeve and its respective guide rod is also ensured. Therefore, the up-and-down lifting movement of the supporting platform frame is smooth and unobstructed. The above solution significantly reduces the wear of the copper guide sleeve and reduces the frequency of equipment shutdown for maintenance. Overview of the Drawings

[0014] A cathode copper plate supporting and lifting stage, the supporting stage 10 connected to a vertically arranged oil cylinder moves up and down in a lifting motion. The copper guide sleeve 30 is formed by enclosing a split-half pipe unit. The copper guide sleeve 30 is placed in a through hole vertically opened on the supporting stage 10. The copper guide sleeve 30 and the vertically arranged guide rod 20 form a sliding fit. There is a flange gland 50 at the outer end of the copper guide sleeve 30, and the flange gland 50 is connected to the supporting stage 10. In the above solution, the flange gland 50 is axially pressed against the outer end of the copper guide sleeve 30, thus achieving axial limit between the copper guide sleeve 30 and the mounting hole of the supporting stage 10 along the axial direction. At this time, no external force is applied to the radial direction of the copper guide sleeve 30. For all the copper guide sleeves 30, the spacing between all the copper guide sleeves 30 and the spacing between the corresponding guide rods 20 are within the allowable error range of the processing accuracy, and no assembly error is increased. Therefore, during the up and down movement of each copper guide sleeve 30, it always operates within the error range, and the lifting action is stable and smooth, significantly reducing the probability of wear of the copper guide sleeve 30.
[0015] As a preferred solution, also referring to Figure 6 , 7 , as shown in Figures 8, an outer steel sleeve 40 formed by enclosing a split-half pipe unit is provided around the copper guide sleeve 30. There is a flange gland 50 at the outer end of the outer steel sleeve 40, and an axial limit fit is formed between the copper guide sleeve 30 and the outer steel sleeve 40. The flange end cover 50 is connected to the supporting stage 10.
[0016] Figure 7 In, there are external flanges 31 at the upper and lower ends of the copper guide sleeve 30. The inner cavity of the outer steel sleeve 40 is a stepped pipe cavity. The middle pipe cavity section of the outer steel sleeve 40 is placed between the flanges 31 at both ends of the copper guide sleeve 30 and forms an axial limit fit. For the specific implementation structure, reference can be made to Figure 5 . The upper end of the outer steel sleeve 40 is a step with a smaller inner diameter and a larger outer diameter, and an annular groove 43 is opened at the lower end. The cavity section between the upper step and the annular groove 43 matches the length between the upper and lower flanges 31 of the copper guide sleeve 30, thus achieving radial constraint and axial positioning of the copper guide sleeve 30 by the outer steel sleeve 40.
[0017] In the above solution, as shown in Figures 3, 4, and 5, an outer steel sleeve 40 is arranged around the outside of the copper bushing 30. Radial positioning is achieved by the through holes that are vertically and horizontally penetrated on the material supporting table frame 10 and the outer steel sleeve 40. The core position of the through holes that are vertically and horizontally penetrated on the material supporting table frame 10 can achieve reliable accuracy through metal processing, thereby achieving the core positioning of the copper bushing 30. Therefore, by implementing processing with a processing device that meets the requirements of processing accuracy, the shape tolerance of each copper bushing 30 and the position tolerance between the copper bushings 30 can be ensured. Furthermore, the fit with the guide rod 20 meets the design accuracy requirements. After assembly, the copper bushing 30 still only contacts the outer steel sleeve 40, and the flange gland 50 is pressed on the outer end face of the outer steel sleeve 40, that is, there is an external flange on the outer end of the outer steel sleeve 40. Therefore, the copper bushing 30 avoids the phenomenon of hole shape deformation or core offset caused by local concentrated stress.
[0018] The flange gland 50 is formed by enclosing two semi-disc units. In this way, after the connecting bolts 60 on the flange gland 50 are disassembled, the separation of the flange gland 50 and the guide rod 20 can be easily achieved, which is convenient for the disassembly and assembly of the copper bushing 30 and the outer steel sleeve 40. In order to improve the lubrication performance of the copper bushing 30, a graphite copper bushing is selected to reduce friction and improve the lubrication performance.
[0019] There is an external flange at the outer end of the outer steel sleeve 40 that abuts against the end face of the through hole that is vertically and horizontally penetrated on the material supporting table frame 10. There is a notch or light hole 41 on the external flange at the outer end of the outer steel sleeve 40 for the bolt 60 to pass through. The bolt 60 is connected to the threaded hole on the material supporting table frame 10, and there is also a threaded hole 42 on the external flange of the outer steel sleeve 40 beside the bolt 60. There are the following advantages in setting the outer steel sleeve 40. First, it gives the copper bushing 30 radial and axial uniform constraints, and there is no deformation or eccentricity of the copper bushing 30. Second, the outer steel sleeve 40 itself has sufficient rigidity and strength to bear the external force given by other components including the flange gland 50 without the risk of deformation. Third, there is a threaded hole 42 on the external flange of the outer steel sleeve 40 for connecting and disassembling bolts. When the disassembling bolt is turned, the bolt end face abuts against the through hole end face on the material supporting table frame 10, so as to smoothly take out the outer steel sleeve 40 together with the copper bushing 30. To ensure convenient disassembly by giving axial uniform force within the circumferential range, several threaded holes 42 are evenly spaced within the circumferential range.
[0020] According to the specific situation of the equipment, two guide rods 20 are arranged in cooperation with the material supporting table frame 10, and a copper bushing 30 is arranged at each through hole at the upper and lower table surfaces of the material supporting table frame 10 for each guide rod 20. That is, two copper bushings 30 arranged at an upper and lower interval cooperate with one guide rod 20, ensuring the stability of the operation of the material supporting table frame 10.
[0021] In addition, through the transformation of the guide sleeve of the flaking lifting mechanism, the maintenance frequency has been fundamentally reduced, and the problem of shutdown for maintenance has been solved. It can save two guide rods (2 * 3000 yuan) and 16 copper guide sleeves (16 * 280 yuan) every year, as well as the maintenance cost of 20 times * 0.2 = 40,000 yuan, with a total of 50,480 yuan. This is the direct cost of maintenance; in addition, the economic loss caused by production suspension is quite huge.
