Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing and demagnetization, in particular to a bearing demagnetization machine. Background Art

[0002] Demagnetization machines are generally used for demagnetization of permanent magnetic materials and low coercive force materials. They can be divided into pulse demagnetization and AC demagnetization. Demagnetization is to place the workpiece under alternating amplitude and gradually decrease the trajectory of the hysteresis loop. When the magnetic field intensity drops to zero, the residual magnetism Br in the workpiece is close to zero. During bearing processing, the bearings need to be demagnetized in multiple passes to prevent impurities from being adsorbed on the bearings during subsequent use, affecting their smooth rotation. After the bearings are wrapped in oil paper, they need to be demagnetized in the demagnetizer for the last pass. As the last process, the demagnetization effect is very important.

[0003] The existing patent with the authorization announcement number "CN219873020U" discloses a demagnetizing machine for bearing production, including a frame, wherein belt rollers are symmetrically arranged inside the frame through bearings, and conveyor belts are sleeved on the surfaces of the two belt rollers. A demagnetizer is arranged above the frame, and the demagnetizer spans above the conveyor belt. A material box is placed on the surface of the conveyor belt. A transmission box is provided on one side of the entry end of the frame, and a motor is provided on the outside of the transmission box. A rotatable baffle is provided on the outside of the equipment. When the material box moves to the tail, it drives the internal mechanism to separate the conveyor belt from the power. At this time, the conveyor belt no longer moves, thereby preventing the material box from falling and improving the installation performance.

[0004] However, there are the following deficiencies in this device:

[0005] 1. After the bearing is demagnetized, some magnetic debris attached to the bearing will fall onto the conveyor belt. However, when the above device is in use, it fails to effectively clean the debris on the conveyor belt, causing the debris to adhere to the conveyor belt and accumulate, affecting the subsequent processing of the bearing;

[0006] 2. When the above device is in use, not only does it require manual labor to continuously take out materials, but it also requires taking out the bearings in the material box before demagnetizing the next set of bearings. Continuous processing is impossible, which reduces the material discharging convenience and processing efficiency of the device. Utility Model Content

[0028] See also Figure 1-6 The utility model provides an embodiment of a bearing demagnetization machine, including a frame 1 and a material box 13. A mounting plate 6 is provided on the top of the frame 1, and universal wheels are provided at the four corners of the bottom of the frame 1 to facilitate the movement of the pushing device. Guide rollers 18 are sleeved on both sides of the inner side of the mounting plate 6, and a conveyor belt 15 is sleeved on the outer sides of the two sets of guide rollers 18. Multiple sets of baffles are evenly arranged on the outer sides of the conveyor belt 15 to prevent the bearing from rolling on the conveyor belt 15 at will. A fixing plate 2 is provided in the middle of one side of the frame 1, and a control box 14 is provided at one end of the fixing plate 2. The output end of the control box 14 and one end of a set of guide rollers 18 are both provided with pulleys 4. The outer sides of the two sets of pulleys 4 are jointly sleeved with belts 3. A demagnetizer 10 is provided on one side of the top of the mounting plate 6, and a heat dissipation and dust removal component is provided on the top of the demagnetizer 10; a control box 14 is provided at one end of the mounting plate 6;

[0029] Connecting plates 12 are provided at both ends of one side of the mounting plate 6, the inner sides of the two groups of connecting plates 12 are sleeved with guide rods 24, the bottoms of the two groups of guide rods 24 are provided with insertion rods 23, the outer sides of the two groups of guide rods 24 are sleeved with springs 19, and the tops of both ends of the material box 13 are provided with sockets 22, the tops of one group of guide rods 24 are provided with movable plates 25, the tops of the movable plates 25 are provided with alarms 11, the bottoms of the movable plates 25 are provided with electric contacts A20, and the tops of one group of connecting plates 12 are provided with electric contacts B21 aligned with the electric contacts A20.

[0030] Furthermore, the heat dissipation and dust removal assembly includes a guide pipe 8, an exhaust pipe 9, a nozzle 16 and a fan 17. The exhaust pipe 9 is provided on the top of the demagnetizer 10, and the fan 17 is provided on the inner side of the exhaust pipe 9. The nozzle 16 is provided on one side of the inner side of the frame 1, and the top of the exhaust pipe 9 is provided with a guide pipe 8 connected to the nozzle 16, which can dissipate heat for the demagnetizer 10 and use the heat dissipation exhaust airflow to clean the conveyor belt 15.

[0031] Furthermore, a protective shell 5 is commonly provided on the outer sides of the two groups of pulleys 4 , and the protective shell 5 is installed on the fixing plate 2 and the mounting plate 6 to protect the pulleys 4 .

[0032] Furthermore, a protective chamber 7 is provided in the middle of the top of the mounting plate 6. The protective chamber 7 is made of a transparent material to reduce the interference of dust on the bearing.

[0033] Furthermore, a rubber buffer pad is provided at the bottom of the inner side of the material box 13, and a plurality of buffer strips are evenly provided on the inner wall of the material box 13. The rubber buffer pad can buffer the damage caused by the bearing falling. The buffer strips can increase the rolling friction of the bearing, reduce its rolling speed, and protect the bearing discharge. After installation, the material box 13 is in an inclined state, which can ensure that the packaged bearings can roll to the bottom of the material box 13 at a uniform speed after demagnetization, thereby preventing the bearings from being damaged by falling too fast.

[0034] Working principle: When the device is used to demagnetize bearings, the packaged bearings can be placed on the conveyor belt 15, and then the control box 14 can be started. The control box 14 can drive a set of pulleys 4 to rotate, and then a set of pulleys 4 can drive another set of pulleys 4 using the transmission of the belt 3 to rotate the guide roller 18. When the guide roller 18 rotates, it can drive the conveyor belt 15 to move, thereby conveying the bearings. When the bearings are conveyed to the inside of the demagnetizer 10, the demagnetizer 10 can be started to demagnetize the bearings. After demagnetization is completed, the bearings will automatically roll into the feed box 13 for collection under the conveyor belt 15;

[0035] When the demagnetizer 10 is running, the fan 17 can be started to drive the air flow in the demagnetizer 10 to dissipate heat. The heat-dissipating exhaust air can enter the guide pipe 8 through the exhaust pipe 9, and then be transported to the nozzle 16 for discharge through the guide pipe 8. The exhaust air can be blown toward the surface of the conveyor belt 15, thereby blowing away the iron filings and impurities adhering to the conveyor belt 15 to prevent them from being adsorbed on the bearings.

[0036] When the bearing rolls into the feed box 13, the rubber buffer pad can buffer the bearing from falling damage, and the buffer strip can increase the friction of the bearing rolling, reduce its rolling speed, and protect the bearing discharge. As the number of bearings in the feed box 13 increases, the guide rod 24 can be driven by gravity to overcome the elastic force of the spring 19 and move downward. When the electric contact block A20 moves downward and contacts the electric contact block B21, the alarm 11 can be automatically activated to remind the staff to replace the feed box 13 to prevent the bearing from falling. It is very convenient to use and there is no need to manually take out the processed bearings continuously. It only needs to replace the feed box 13 regularly.

[0037] When the material box 13 is replaced, the material box 13 can be removed by simply pulling out the socket 22 from the outside of the insertion rod 23, and then inserting the socket 22 on the replaced material box 13 into the insertion rod 23 to complete the installation.
