Description

Technical Field

[0001] The utility model relates to the technical field of metal electrolytic polishing, and particularly relates to a double-layer heat-insulating electrolytic cell for processing metal spare parts. Background Art

[0002] A common method of metal surface treatment is electrolytic polishing. By placing a metal workpiece in an electrolyte and using an electric current to remove impurities and non-uniformities on its surface, this method is widely used for different types of metals, such as aluminum, copper, and stainless steel, to improve their appearance and quality. The structure of the double-layer heat-insulating electrolytic cell mainly consists of an inner and an outer layer of the cell: the inner cell is the main body of the electrolytic cell, which is used to hold the electrolyte and the workpiece, and is usually made of corrosion-resistant materials; the outer cell wraps the inner cell and is filled with heat-insulating materials, such as fiberglass wool or foamed polyurethane, effectively reducing heat loss. The heating system provides a constant heating energy through electric heating tubes or a hot oil circulation system to keep the electrolyte at a constant temperature, while the electrolyte circulation system ensures uniform circulation of the liquid, avoiding the adverse effects of temperature gradients on the polishing quality. The constant temperature state and uniform electrolyte circulation help to form a uniform electric field and current density distribution, thereby achieving a uniform polishing effect on the metal surface. However, at present, during the immersion and extraction processes of metal spare parts in the double-layer heat-insulating electrolytic cell, the height of the cage in the electrolytic cell needs to be manually controlled by the staff. Due to the large weights of the cage and the metal spare parts, it is difficult for the staff to load and lift the materials. Especially during frequent operations, long-term repetitive labor will cause fatigue and physical discomfort to the staff. At the same time, the processes of manual loading and lifting require corresponding downtime. When a large number of workpieces need to be processed quickly, frequent downtime will also reduce the operation continuity of the electrolytic cell. Content of the Utility Model

[0003] The purpose of the utility model is to provide a double-layer heat-insulating electrolytic cell for processing metal spare parts, so as to solve the problems raised in the above background art.

[0004] To achieve the above object, the present utility model provides the following technical solution: A double-layer heat-insulating electrolytic cell for processing metal spare parts, comprising an electrolytic cell body and an outer heat-insulating sleeve sealed and installed on the outer peripheral surface of the electrolytic cell body. A vacuum layer is provided between the electrolytic cell body and the outer heat-insulating sleeve. I-shaped inverted beams are fixedly arranged on the front and rear sides of the top end of the electrolytic cell body. Two symmetrically arranged rotating shafts are rotatably installed on the outer walls of the opposite sides of the two I-shaped inverted beams. A longitudinal beam frame is fixed between the two rotating shafts in the same Y-axis direction. A cage box is fixed at the bottom end of the longitudinal beam frame. Sealing plates are hinged and installed on the outer walls of the opposite sides of the two cage boxes through hinges. A gear transmission structure is installed between the two rotating shafts in the same X-axis direction. A rotating drive unit for driving the rotation of the rotating shaft is installed on the outer wall of one side of one of the I-shaped inverted beams. A motor controller electrically connected to the input end of the rotating drive unit is installed on one side of the surface of the electrolytic cell body.

[0005] Preferably, an inclined downward extending slope surface is provided at the bottom end of the electrolytic cell body.

[0006] Preferably, the rotating drive unit comprises a motor installed on the outer wall of one side of one of the I-shaped inverted beams, a speed reducer installed at the output end of the motor, and a coupling installed at the output end of the speed reducer for connecting with one end of one of the rotating shafts.

[0007] Preferably, a plurality of rectangular hollow-out grooves are provided on the outer peripheral surface of the cage box.

[0008] Preferably, the gear transmission structure is a tooth disc fixed at one end of the rotating shaft, and the two tooth discs are meshed with each other.

[0009] Preferably, the longitudinal beam frame is composed of three rectangular long beams and rectangular columns fixed at the same end of the three rectangular long beams.

[0010] Compared with the prior art, the beneficial effect of the present utility model is that: The double-layer heat-insulating electrolytic cell for processing metal spare parts converts the rotational motion of the rotating drive unit into the rotational immersion and immersion-out actions of the cage box through the mutually cooperating structures such as the rotating drive unit and the cage box. After the cage box and the metal spare parts sink into the electrolytic cell body, the metal spare parts are subjected to electrolytic polishing treatment inside the electrolytic cell body. The rotational design of the cage box eliminates the process of manual feeding and lifting by workers, significantly reducing their labor intensity. At the same time, the automated rotational method can achieve rapid cyclic operation, reducing the processing time of the workpiece in the electrolytic cell and the shutdown duration of the electrolytic cell body.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a double-layer heat-insulated electrolytic cell for metal parts processing, including an electrolytic cell body 1 and an outer thermal insulation sleeve 2 hermetically installed on the outer peripheral surface of the electrolytic cell body 1. A vacuum layer 102 is provided between the electrolytic cell body 1 and the outer thermal insulation sleeve 2. The electrolytic cell body 1 generates heat during operation, especially during the electrolysis reaction, and the temperature may rise. The outer thermal insulation sleeve 2 and the vacuum layer 102 between the electrolytic cell body 1 and the outer thermal insulation sleeve 2 can effectively prevent heat from dissipating from the electrolytic cell body to the outside, thereby maintaining the temperature stability inside the cell;

[0019] On the front and rear sides of the top of the electrolytic cell body 1, inverted I-beams 4 are fixedly installed. On the outer walls of the opposite sides of the two inverted I-beams 4, two symmetric rotating shafts 5 are rotatably installed. A longitudinal beam frame 6 is fixed between the two rotating shafts 5 in the same Y-axis direction, and the bottom end of the longitudinal beam frame 6 is fixed with a cage box 8. A plurality of rectangular hollow grooves are provided on the outer peripheral surface of the cage box 8. On the outer walls of the opposite sides of the two cage boxes 8, a sealing plate 10 is hingedly installed through a hinge. A gear transmission structure 7 is installed between the two rotating shafts 5 in the same X-axis direction. On the outer wall of one side of one of the inverted I-beams 4, a rotation drive unit 9 for driving the rotation of the rotating shaft 5 is installed. On one side of the surface of the electrolytic cell body 1, a motor controller 3 electrically connected to the input end of the rotation drive unit 9 is installed;

[0020] The bottom end of the electrolytic cell body 1 is provided with a slope surface portion 101 extending obliquely downward, and the slope surface portion 101 is used to make the impurities generated during the electrolysis process settle down;

[0021] The inside of the electrolytic cell body 1 is equipped with electrodes, usually an anode and a cathode. The electrolyte circulates inside the cell, and the current in the electrolytic cell is transmitted to the metal fittings through the electrodes, thereby triggering an electrolysis reaction to remove surface oxides and impurities, ensuring that the metal fittings are evenly affected by the electrolyte during the immersion process to achieve an efficient polishing effect;

[0022] The longitudinal beam frame 6 is composed of three rectangular long beams and rectangular columns fixed at the same end of the three rectangular long beams. The rotary drive unit 9 includes a motor installed on the outer wall of one side of one inverted I-beam 4, a reducer installed at the output end of the motor, and a coupling installed at the output end of the reducer and used to connect with one end of one rotating shaft 5. The rotary drive unit 9 is composed of a motor, a reducer, and a coupling. The rotational force generated by the motor reduces the rotational speed and increases the torque through the reducer, ensuring the stability and reliability of the cage 8 during the immersion and lifting processes;

[0023] The gear transmission structure 7 is a toothed disc fixed at one end of the rotating shaft 5. The two toothed discs mesh with each other. One of the rotating shafts 5 is driven to rotate by the rotary drive unit 9, so that the longitudinal beam frame 6 and the cage 8 in one Y-axis direction deflect. The other rotating shaft 5 on the X-axis rotates synchronously and reversely under the drive of the gear transmission structure 7. That is, at this time, the two cages 8 flip synchronously and reversely, jointly realizing the functions of immersing and leaching the workpiece. It ensures that the immersion and leaching heights of the cage 8 are the same, so that each workpiece is processed under the same conditions.

[0024] When the embodiment of the present application is in use, first, the staff opens the sealing plate 10 so as to form an opening on the side wall of the cage 8. At this time, the staff can send the metal spare parts to be electrolytically polished into the cage 8 and then close the sealing plate 10. Subsequently, the staff starts the rotary drive unit 9 to work through the motor controller 3. The motor controller 3 is responsible for controlling the start, stop, speed and direction of the motor, that is, the motor controller 3 adjusts the operating state of the motor according to a preset program to ensure that the rotation of the rotating shaft 5, the longitudinal beam frame 6 and the cage 8 matches the electrolysis process. That is, the rotating shaft 5, the longitudinal beam frame 6 and the cage 8 are driven to rotate through the rotary drive unit 9. During this process, the longitudinal beam frame 6 and the cage 8 rotate around the longitudinal beam frame 6 until the rotational motion of the motor is converted into the immersion and leaching actions of the cage 8. When the cage 8 and the metal spare parts sink into the electrolytic cell body 1, the metal spare parts are electrolytically polished inside the electrolytic cell body 1. The rotational design of the cage 8 eliminates the process of manual feeding and lifting by the staff, significantly reducing their labor intensity. At the same time, the automated rotation method can achieve rapid cyclic operation, reducing the processing time of the workpiece in the electrolytic cell and the downtime of the electrolytic cell body 1, thereby improving the overall production efficiency.
