Description

Technical Field

[0001] The utility model relates to the technical field of bearing production, in particular to a bearing stamping retainer. Background Art

[0002] A cage (also called a bearing retainer) refers to a bearing part that partially wraps all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually guide the rolling elements and keep them in the bearing.

[0003] During the production and processing of the cage, stamping equipment is used for forging. However, in the production of commonly used bearing cages, the punch head is usually installed directly above the stamping die. This structural design is easy to cause damage to the operator during operation and has low safety. In addition, during the processing of the bearing cage, waste will be generated, which is not conducive to centralized collection. After processing, cleaning up the waste will increase the workload, increase the single production time, and affect production efficiency. How to invent a bearing stamping cage to improve these problems has become an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0011] Preferably, the threaded block is slidably connected to the movable groove, the threaded block is threadedly connected to the screw rod, one end of the screw rod is rotatably connected to the inner wall of the movable groove away from the support plate, and the other end of the screw rod passes through the side wall of the fixed platform and is fixedly connected to the gear plate.

[0012] By adopting the above technical solution, when the cylinder drives the punching head to punch the retaining frame, the gear plate drives the screw rod to rotate through the connection between the pressure rod and the tooth plate and the meshing connection between the tooth plate and the gear plate, and then the placement table moves on the fixed table through the threaded connection between the screw rod and the threaded block. At the same time, the sliding of the slider and the slide rod, as well as the stretching or squeezing of the telescopic spring, increase the stability of the placement table and avoid deviation when the retaining frame is stamped.

[0013] Preferably, a discharge groove is provided on the side wall at one end of the placement table, and the side wall at the end of the discharge groove away from the opening is slidably connected to the push rod, one end of the push rod is fixedly connected to the push plate, and the push plate is arranged in an arc shape, and the other end of the push rod is fixedly connected to the docking block, one end of the push rod is located on the inner side of the return spring, and the two ends of the return spring are respectively fixedly connected to the side wall of the placement table and the side wall of the docking block.

Due to the action of the threaded block, the placement table moves toward the side of the support plate on the fixed table. At the same time, the slider, the slide bar and the telescopic spring are used to increase the stability of the placement table during movement and processing, so as to avoid deviation when punching the retainer; when the tooth plate is disengaged from the gear plate, the punch head will continue to move downward, so that the extrusion block is extruded against the butt block, and at the same time the reset spring is stretched and the push plate is located on one side of the punching hole of the placement table. After the punching is completed, the waste will fall into the discharge trough. Then, when the punch head moves up, the reset spring resets and drives the push plate to push the waste into the collection frame, so as to facilitate the automatic centralized collection of the waste, reduce manual intervention, and improve safety and production efficiency. When the punch head moves up to the initial state, the placement table also returns to its original position. This operation method facilitates the removal of the retainer and the next processing of the retainer, and avoids possible damage to the operator during the processing.

[0028] It should be noted that: in the initial state, the placement table 10 is at one end of the fixed table 11 away from the support plate 5. When in use, the cylinder 6 drives the punch head 8 to move downward. At this moment, the pressure rod 4 drives the tooth plate 3 to move downward together. During the movement, the tooth plate 3 passes through the through hole 13, and the gear plate 12 is meshed with the tooth plate 3 so that the gear plate 12 drives the screw rod 18 to rotate. Due to the threaded connection between the screw rod 18 and the threaded block 25, the placement table 10 moves on the fixed table 11 toward the side of the support plate 5. At the same time, through the sliding between the slider 20 and the slide rod 15 and the stretching or squeezing of the telescopic spring 14 by the slider 20, the stability of the placement table 10 during movement and processing is increased to avoid deviation when stamping the retaining frame.

[0029] Reference Figure 3-Figure 4 , further; a discharge groove 21 is opened on the side wall of one end of the placement table 10, and the side wall of the end of the discharge groove 21 away from the opening is slidably connected to the push rod 23, one end of the push rod 23 is fixedly connected to the push plate 22, the push plate 22 is arranged in an arc shape, and the other end of the push rod 23 is fixedly connected to the docking block 9, one end of the push rod 23 is located on the inner side of the return spring 24, and the two ends of the return spring 24 are respectively fixedly connected to the side wall of the placement table 10 and the side wall of the docking block 9.

[0030] It should be noted that: in the above process, due to the action of the tooth plate 3 and the gear plate 12, the placement table 10 gradually moves to the bottom of the punch head 8. At this time, the tooth plate 3 is separated from the gear plate 12, and the punch head 8 continues to move downward through the action of the cylinder 6. At this time, the inclined surface of one end of the extrusion block 7 will squeeze the inclined surface of one end of the docking block 9. Through the sliding extrusion of the two, the docking block 9 moves to the side away from the placement table 10. In this process, the docking block 9 will stretch the reset spring 24 and drive the push rod 23 and the push plate 22 to move, and finally the push plate 22 is located on one side of the punching hole of the placement table 10. When the retainer stamping is completed The waste will then fall into the discharge trough 21, and then when the punch head 8 moves up, the reset spring 24 resets to drive the push plate 22 to push the waste into the collection frame 2 for automatic centralized collection of the waste. When the punch head 8 moves up to the initial state, the placement table 10 also returns to its original position, and the holder after stamping is moved out for subsequent retrieval and the next processing, thereby avoiding possible damage to the operator during the processing; in addition, after the tooth plate 3 is separated from the gear disk 12, one end of the tooth plate 3 may contact the ground. At this time, the compression spring 19 can be squeezed by the pressure rod 4 to ensure the normal operation of the pressure rod 4.

[0031] The working principle of this method is as follows: in the initial state, the placement table 10 is at one end of the fixed table 11 away from the support plate 5. When in use, the cylinder 6 drives the punch head 8 to move downward, and at this moment, the pressure rod 4 drives the tooth plate 3 to move downward together. During the movement, the tooth plate 3 passes through the through hole 13, and the meshing connection between the tooth plate 3 and the gear plate 12 causes the gear plate 12 to drive the screw rod 18 to rotate. Due to the threaded connection between the screw rod 18 and the threaded block 25, the placement table 10 moves on the fixed table 11 toward the side of the support plate 5. At the same time, through the sliding between the slider 20 and the slide rod 15 and the stretching or squeezing of the telescopic spring 14 by the slider 20, the stability of the placement table 10 during the movement and processing process is increased to avoid deviation when punching the retainer.

[0032] In the above process, due to the action of the toothed plate 3 and the gear plate 12, the placement table 10 gradually moves to the right below the punch head 8. At this time, the toothed plate 3 is separated from the gear plate 12, and the punch head 8 continues to move downward through the action of the cylinder 6. At this time, the inclined surface of one end of the extrusion block 7 will squeeze the inclined surface of one end of the docking block 9. Through the sliding extrusion of the two, the docking block 9 moves to the side away from the placement table 10. In this process, the docking block 9 will stretch the reset spring 24 and drive the push rod 23 and the push plate 22 to move, and finally the push plate 22 will be located on one side of the punching hole of the placement table 10. After the stamping of the retainer is completed, the waste will It falls into the discharge trough 21, and then when the punch head 8 moves up, the reset spring 24 resets to drive the push plate 22 to push the waste into the collection frame 2 for automatic centralized collection of the waste. When the punch head 8 moves up to the initial state, the placement table 10 also returns to its original position, and the stamped retaining frame is moved out for subsequent retrieval and the next processing, avoiding possible damage to the operator during the processing; in addition, after the tooth plate 3 is separated from the gear disk 12, one end of the tooth plate 3 may contact the ground. At this time, the compression spring 19 can be squeezed by the pressure rod 4 to ensure the normal operation of the pressure rod 4.

[0033] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
