Description

Technical Field

[0001] This utility model relates to the field of hard chrome plating technology, specifically to an automatic hard chrome plating production device. Background Technology

[0002] Hard chrome plating is a traditional surface electroplating technique that has been used for over 70 years. Chromium plating layers are highly hard, wear-resistant, corrosion-resistant, and can maintain a bright surface for a long time. The process is relatively simple and the cost is low.

[0003] For example, a casting mold hard chrome plating production device with authorization announcement number "CN221918305U" allows for easy installation by simply placing the mold in the center, resulting in higher efficiency and more uniform chrome plating under the drive motor. However, this device requires workers to frequently move the casting mold to the device for hard chrome plating, increasing labor costs. Furthermore, electrolyte residue remains on the casting mold when it is removed from the electrolyte solution, making it inconvenient for workers to pick it up, thus reducing its practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the need for workers to frequently move the casting molds to the device for hard chrome plating when plating casting molds, which increases the labor cost and leaves electrolyte residue on the casting molds when they are removed from the electrolyte, making it inconvenient for workers to pick them up, thus reducing the practicality of the invention.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an automatic hard chrome plating production device, including a frame and a base. The lower end of the frame is fixedly connected to the base. A moving mechanism is installed on the upper left side of the frame. The upper inner wall of the frame is fixedly connected to a cylinder. The output end of the cylinder is fixedly connected to a cover. A vibration mechanism is installed on the lower left side of the cover. A cylinder is fixedly connected to the lower middle part of the cover. Both sides of the cylinder are threaded with bolts. The ends of the bolts are fixedly connected with rubber layers. An electroplating tank is fixedly connected to the upper right side of the base. A discharge port is provided on the lower right side of the electroplating tank.

[0007] Preferably, the moving mechanism includes a first housing, the right end of which is fixedly connected to a frame, the inner wall of which is fixedly connected to a first motor via a bracket, the output shaft of the first motor being connected to the rotating shaft of a connecting rod via a reduction gearbox, the inner wall of the connecting rod being rotatably connected to the first housing via the rotating shaft, the inner wall of the connecting rod being rotatably connected to a roller via a bearing, and the outer wall of the roller being in contact with a bending plate.

[0008] Preferably, the lower outer wall of the bent plate is slidably connected to the first housing, the two inner walls of the bent plate are slidably connected to the crossbar, and both ends of the crossbar are fixedly connected to the first housing.

[0009] Preferably, the vibration mechanism includes a second housing, the upper end of which is fixedly connected to the cover, the inner wall of which is fixedly connected to a second motor via a bracket, the output shaft of which is connected to the rotating shaft of the block via a coupling, the inner wall of which is rotatably connected to the second housing via the rotating shaft, the outer wall of which is in contact with the horizontal plate, the outer walls of which are slidably connected to the second housing on both sides, and the right end of which is provided with a rubber layer, which is in contact with the cylinder via the rubber layer.

[0010] Preferably, the inner wall of the cross plate is slidably connected to the support block, both sides of the support block are fixedly connected to the second housing, a rod is fixedly connected to the right end of the support block, a spring is provided on the outer wall of the rod, the two ends of the spring are fixedly connected to the support block and the cross plate respectively, and the outer wall of the rod is slidably connected to the cross plate.

[0011] Preferably, the inner wall of the discharge port is equipped with a solenoid valve, a platform is fixedly connected to the lower left side of the frame, the lower end of the platform is fixedly connected to the base, a conveyor belt is fixedly connected to the upper left side of the base, and the upper end of the conveyor belt is in contact with the box body.

[0012] The present invention proposes an automatic hard chrome plating production device, the advantages of which are as follows: through the cooperation of the moving mechanism and the frame, the first motor drives the connecting rod to rotate clockwise, the connecting rod drives the roller to rotate, and the roller drives the bending plate to move to the right through the slide groove. The outer wall of the bending plate and the box body then push the box body from the conveyor belt to the platform. When the first motor continues to rotate, the roller drives the bending plate to move to the left through the slide groove. After the bending plate moves to the left and returns to its original position, the first motor is turned off. In the above manner, the bending plate pushes the box body on the conveyor belt to the platform, thus eliminating the need for workers to frequently move steel pipes, thereby reducing the labor force of workers.

[0013] Through the cooperation of the vibration mechanism and the cover, the second motor drives the block to rotate counterclockwise. The block drives the horizontal plate to move to the left. At this time, the spring contracts. When the block separates from the horizontal plate, the spring rebounds and drives the horizontal plate to move to the right, thus striking the cylinder. When the block is in contact with the horizontal plate again, it will drive the horizontal plate to move to the left again. In this way, the horizontal plate repeatedly strikes and vibrates the cylinder. The vibration generated by the cylinder is transmitted to the steel pipe, which in turn shakes down the solution containing plating metal cations remaining on the surface of the steel pipe. This striking and vibration of the hard chrome-plated steel pipe reduces the solution containing plating metal cations on the steel pipe, making it easier for workers to pick up the steel pipe and thus increasing its practicality.

[0029] Working principle: (The hard chrome plated pipe is made of steel)

[0030] When hard chrome plating of the steel pipe is required, the external power supply of the conveyor belt 11 is turned on and started. The conveyor belt 11 moves the housing 12 (containing the steel pipe). After the housing 12 moves to the front of the bending plate 205, the conveyor belt 11 is turned off. Then, the external power supply of the first motor 202 is turned on and started. The first motor 202 drives the connecting rod 203 to rotate clockwise. The connecting rod 203 drives the roller 204 to rotate. The roller 204 drives the bending plate 205 to move to the right through the slide groove. The outer wall of the bending plate 205 and the housing 12 then push the housing 12 from the conveyor belt 11 onto the platform 10 (at this time, the bending plate 205 has moved to the right to its maximum distance). As the first motor 202 continues to rotate, the roller 204 drives the bending plate 205 to move to the left through the slide groove (e.g., ...). Figure 3 After the bending plate 205 moves to the left and resets, the first motor 202 is turned off. In this way, the bending plate 205 pushes the box 12 on the conveyor belt 11 onto the platform 10, so that workers do not need to frequently move the steel pipes.

[0031] Then the worker takes the steel pipe out of the box 12, places the steel pipe in the cylinder 6 and rotates the bolt 7 to make the rubber pad at the end of the steel pipe press against the steel pipe, thus fixing the steel pipe in the cylinder 6. After the cylinder is fixed, the external power supply of the cylinder 4 is turned on and started. The output end of the cylinder 4 extends and drives the cover 5 to move downward, thus driving the fixed steel pipe 10 to move downward. After the cover 5 is in contact with the electroplating box 8, the cylinder 4 is closed. At this time, the steel pipe 10 is immersed in the solution containing the plating metal cations that has been stored in the electroplating box 8 (the electrolyte can be discharged from the electroplating box 8 by opening the outlet 9 through the valve). Then the wire of the electroplating box 8 is connected to the external power supply. The steel pipe in the electroplating box 8 is immersed in the solution containing the plating metal cations as the cathode. At the same time, the metal plate is used as the anode. After the DC power is turned on, the plating metal cations form a plating layer on the surface of the workpiece to be plated, thus automatically performing hard chrome plating on the steel pipe (the electroplating box 8 is existing technology, and the above operations can be achieved in existing technology).

[0032] After the hard chrome plating of the steel pipe is completed, the output end of cylinder 4 retracts, causing the cover 5 to move upwards to its reset position. After the cover 5 resets, cylinder 4 is closed. At this time, the hard chrome-plated steel pipe is removed from the electroplating tank 8. The external power supply of the second motor 302 is connected and started. The second motor 302 drives the block 303 to rotate counterclockwise. The block 303 drives the horizontal plate 4 to move to the left. At this time, the spring 307 contracts. When the block 303 separates from the horizontal plate 304, the spring 307 rebounds, causing the horizontal plate 304 to move to the right and strike the cylinder 6. When the block 303... After 03 is attached to the horizontal plate 304 again, it will drive the horizontal plate 304 to move to the left again. In the above way, the horizontal plate 304 repeatedly knocks and vibrates the cylinder 6. The vibration generated by the cylinder 6 is transmitted to the steel pipe, which in turn shakes down the solution containing plating metal cations on the surface of the steel pipe. By knocking and vibrating the hard chrome plated steel pipe in the above way, the solution containing plating metal cations on the steel pipe is reduced, making it easier for workers to pick up the steel pipe. After the solution containing plating metal cations on the steel pipe is reduced, the second motor 302 is turned off.

[0033] Reverse bolt 7 removes the steel pipe from the cylinder 6. Then, the worker removes the hard chrome-plated steel pipe (the steel pipe inside the cylinder 6 is not hard chrome-plated and needs to be hard chrome-plated later using small equipment). Then, the next steel pipe is taken out from the box 12 and hard chrome-plated. After all the steel pipes in the box 12 are hard chrome-plated, the box 12 is removed from the platform 10. Then, the next box 12 is moved to the front of the bending plate 205 by the conveyor belt 11. The bending plate 205 is used to push the next box 12 onto the platform 10 in the above manner, and the steel pipes in the next box 12 are hard chrome-plated. The steel pipes are hard chrome-plated in the above manner.

[0034] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
