Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically a stamping die for processing bearing intermediate rings. Background Technology
[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Based on the different frictional properties of the moving elements, bearings can be divided into two main categories: rolling bearings and sliding bearings. The intermediate ring of the bearing is produced by stamping.
[0003] During the stamping process of the bearing intermediate ring, the feeder continuously conveys the material strip into the stamping die. However, the material strip is pulled for a long length during the conveying process, and its position is prone to deviation. This deviation during stamping leads to an increase in the defect rate.
[0004] Therefore, we propose a stamping die for machining the intermediate ring of a bearing. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The stamping die for machining the intermediate ring of the bearing is equipped with a threaded rod and a moving plate. Rotating the knob drives the threaded rod to rotate, which in turn causes the moving plate to move the telescopic block. When the material strip deviates, one side of the roller contacts the side of the material strip, causing the roller to roll.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 4This utility model provides a stamping die for processing a bearing intermediate ring, including a die body 1. A base plate 2 is provided on one side of the die body 1. Traction rollers 3 are symmetrically arranged on the top of the base plate 2. An adjusting roller 15 located on one side of the traction rollers 3 is provided on the top of the base plate 2. A limiting groove 17 located between two traction rollers 3 is opened in the middle of the base plate 2. A mounting horizontal plate 4 is fixedly installed in the middle of the two sets of traction roller 3 supports. A support frame 5 is fixedly installed at the bottom of the middle of the mounting horizontal plate 4. A threaded rod 6 is rotatably connected through one side of the support frame 5. A movable plate 7 located inside the support frame 5 is threadedly connected through the threaded rod 6. A telescopic frame 8 is fixedly installed on one side of the movable plate 7. The telescopic frame 8 is through the middle of the mounting horizontal plate 4. A rotating bracket 9 located between the two mounting horizontal plates 4 is fixedly installed at the other end of the telescopic frame 8. A roller 10 is rotatably connected to the opposite face of the two rotating brackets 9. A connecting plate 16 is fixedly installed at the bottom of the rotating bracket 9. A sliding block 18 is slidably connected inside the limiting groove 17. The top of the sliding block 18 is fixedly installed to the bottom of the connecting plate 16. A deflection rod 19 located below the base plate 2 is movably connected to the bottom of the sliding block 18. The other end of the deflection rod 19 is rotatably connected to one end of the bottom of the adjusting roller 15. By setting the deflection rod 19, when the material deviates and drives the roller 10 on one side to rotate, it squeezes the roller 10, causing the telescopic sleeve 802 of the telescopic frame 8 to retract. Then, the sliding block 18 is moved through the connecting plate 16, which in turn drives the deflection rod 19 to rotate. The other end of the deflection rod 19 drives the sliding seat 13 to drive the adjusting roller 15 to move in the opposite direction of the material belt deviating, which in turn causes the material belt to move in the opposite direction of the deviating direction, thus making the material belt return to the center. When the sliding seat 13 moves, the telescopic frame 8 of the other telescopic frame 8 extends under the action of the other deflection rod 19, which stretches the spring 803, further increasing the pulling force of the sliding seat 13 to return to the center.
[0023] The base plate 2 has a sliding groove 12 located on one side of the traction roller 3. A limiting slide rod 14 located directly below the sliding groove 12 is fixedly installed at the bottom of the base plate 2. A sliding seat 13 is slidably connected inside the sliding groove 12. The middle part of the sliding seat 13 is threadedly connected to the limiting slide rod 14. The adjusting roller 15 is fixedly installed at the top of the sliding seat 13.
[0024] The middle part of the deflection rod 19 is rotatably connected to the bottom of the base plate 2. One end of the deflection rod 19 is provided with a long strip groove. One end of the deflection rod 19 is slidably connected to the bottom of the sliding block 18 through the long strip groove. The other end of the deflection rod 19 is rotatably connected to one end of the sliding seat 13.
[0025] One end of the threaded rod 6 is rotatably connected to the mounting plate 4, and the other end of the threaded rod 6 is fixedly mounted with a knob 11 located on the outside of the support frame 5.
[0026] The other side of the support frame 5 is rotatably connected to the guide slide rod 20, and the other end of the movable plate 7 is slidably connected to the guide slide rod 20. One end of the guide slide rod 20 is fixedly installed to the mounting plate 4.
[0027] Two rotating brackets 9 are symmetrically arranged inside the mounting plate 4. The rotating brackets 9 are rotatably connected to three rollers 10, which are arranged in parallel.
[0028] The telescopic frame 8 includes a telescopic rod 801 fixedly installed with the movable plate 7. The other end of the telescopic rod 801 is slidably fitted with a telescopic sleeve 802. The rotating bracket 9 is fixedly installed with the other end of the telescopic sleeve 802. The other end of the telescopic rod 801 is provided with a spring 803 located inside the telescopic sleeve 802. By setting the threaded rod 6 and the movable plate 7, rotating the knob 11 and driving the threaded rod 6 to rotate will cause the movable plate 7 to drive the telescopic block to move. When the material belt deviates, the roller 10 on one side contacts the side of the material belt, thereby causing the roller 10 to roll. At the same time, the roller 10 generates a force on the material belt in the opposite direction of deviation to prevent the material belt from continuing to deviate.
[0029] Working principle:
[0030] Rotating knob 11 causes threaded rod 6 to rotate, which in turn causes moving plate 7 to move telescopic block. When the material belt deviates, one side roller 10 contacts the side of the material belt, causing roller 10 to roll. At the same time, roller 10 exerts a force on the material belt in the opposite direction of deviation to prevent the material belt from deviating further. When the material belt deviates and causes one side roller 10 to rotate, it squeezes roller 10, causing telescopic sleeve 802 of telescopic frame 8 to retract. This causes sliding block 18 to move through connecting plate 16, which in turn causes deflection rod 19 to rotate. The other end of deflection rod 19 causes sliding seat 13 to move adjusting roller 15 in the opposite direction of material belt deviation, causing the material belt to move in the opposite direction of deviation and thus straighten the material belt. When sliding seat 13 moves, telescopic frame 8 of another telescopic frame 8 extends under the action of another deflection rod 19, causing spring 803 to stretch, further increasing the centering force of sliding seat 13.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
