Description

Technical Field

[0001] The utility model relates to the technical field related to bearing ring production and processing, in particular to a feeding device for forging bearing rings. Background Art

[0002] To ensure safe production, improve production efficiency, ensure product quality, and reduce production costs, a feeding device is required to transport the bearing rings during forging. However, impurities may be present on the surface of the bearing rings during transportation. During high-temperature heat treatment, these impurities may mix with the bearing rings, affecting the quality of the finished product. Patent document CN 215887172 U discloses a feeding device for heat treatment of bearing rings. The device uses a high-pressure air pump in conjunction with an air gun to spray air onto the surface of the bearing rings, thereby removing impurities from the surface of the bearing rings.

[0003] However, this device can only blow off impurities on the surface of the bearing ring, but cannot collect these floating impurities. As a result, the floating impurities will still come into contact with the bearing ring, thereby re-contaminating the bearing ring. This has a major defect. For this reason, we propose a feeding device for forging bearing rings. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The feeding device for forging a bearing ring is provided with a discharge pipe and a blower.

[0027] Working principle: When the drive motor 18 is started to drive the sieve plate 11 and the bearing ring on its upper end to rotate, the air pump 19 and the fan 17 are started. Through the air pump 19, in conjunction with the air gun 191, high-pressure air can be sprayed on the surface of the bearing ring to remove impurities on its surface.

The second movable plate 23 and the first movable plate 22 are slidably installed on the upper and lower sides of the movable frame 21; the lower ends of the two limiting slide rails 2 are fixedly installed with a first limiting rotating seat 28, and the first rotating rod 24 is rotatably installed in the first limiting rotating seat 28. The outer periphery of the first rotating rod 24 is fixedly installed with a first rotating plate 25 rotatably connected to the first movable plate 22. The lower end of the sieve plate 11 is fixedly installed A second rotating rod 26 is installed, and a second rotating plate 27 rotatably connected to the second movable plate 23 is fixedly installed at the lower end of the second rotating rod 26. The length of the second rotating plate 27 is twice the length of the first rotating plate 25; a second limiting rotating seat 3 set in a C shape is fixedly installed at the outer end of one side of the limiting slide rail 2, and a second rotating block 32 and a first rotating block 31 are rotatably installed on the upper and lower sides of the second limiting rotating seat 3, respectively. The second rotating block 32 and the second rotating rod 26 and the first rotating rod 24 and the first rotating block 31 are rotatably connected to each other through transmission belts; the second A limited insertion hole 33 is provided in the middle of the rotating block 32 and the first rotating block 31, and a driven gear 34 is provided in the middle of the second limited rotating seat 3. The upper and lower ends of the driven gear 34 are fixedly installed with limit rods 35 that are plugged into the limit insertion holes 33 on both sides; an electric push rod 36 is fixedly installed in the second cavity 15, and the limit rod 35 is rotatably installed on the upper end of the output shaft of the electric push rod 36. The upper end of the drive motor 18 is fixedly installed with a first driving gear 38 and a second driving gear 39 through its output shaft; the second rotating rod 26 includes a rotating rod A4 and a rotating rod B41, and the rotating rod B A rotating frame 43 is fixedly installed at the lower end of 41, and a rotating disk 42 rotatably connected to the lower end of the rotating frame 43 is fixedly installed at the upper end of the rotating rod A4. A groove 44 is provided on the periphery of the rotating disk 42, and a positioning slot 45 corresponding to the number and position of the grooves 44 is provided on the inner wall of the rotating frame 43. A limiting rod 47 is fixedly installed in the groove 44, and a positioning block 46 is provided in the groove 44 to be plugged into the limiting rod 47. The outer end of the positioning block 46 is engaged with the positioning slot 45, and a spring 48 is fixedly installed between the positioning block 46 and the groove 44 and is sleeved on the periphery of the limiting rod 47.

[0029] Specifically, when it is necessary to drive the sieve plate 11 and the bearing rings at its upper end to reciprocate, and to improve the cleaning effect of impurities on the surface of the bearing rings through the contact between the bearing rings, the electric push rod 36 is started, and the electric push rod 36 drives the driven gear 34 to move downward through its output shaft, so that the limit rod 35 is plugged into the first rotating block 31 and separated from the second rotating block 32. At this time, the driven gear 34 is engaged with the first driving gear 38, and the drive motor 18 is started. The drive motor 18 drives the driven gear 34 to rotate through its output shaft, and cooperates with the transmission belt to drive the first rotating rod 24 to rotate with it;

[0030] The rotating first rotating rod 24 is connected to the first rotating plate 25 and the first movable plate 22, and to the second rotating plate 27 and the second movable plate 23 through the sliding connection between the movable frame 21 and the limiting slide rail 2, and between the movable frame 21 and the second movable plate 23 and the first movable plate 22. The length of the second rotating plate 27 is twice the length of the first rotating plate 25.

When the first rotating plate 25 continues to rotate and drives the movable frame 21 to slide in the opposite direction, it can drive the second rotating rod 26 to rotate in the opposite direction, thereby driving the screen plate 11 and the bearing ring on the upper end thereof to reciprocate.

[0031] When it is necessary to drive the sieve plate 11 to rotate and cooperate with the feeding guide plate 12 to feed the bearing ring, the electric push rod 36 is started, so that the limit rod 35 is plugged into the second rotating block 32 and separated from the first rotating block 31. At this time, the driven gear 34 and the second driving gear 39 are meshed with each other, and the driving motor 18 is started, which can directly drive the second rotating rod 26 and the upper end sieve plate 11 to rotate in one direction;

[0032] Among them, when the second rotating plate 27 rotates to the point where the movable frame 21 contacts the outer side of the inner cavity of the limiting slide rail 2, the rotating frame 43 and the rotating disk 42 are connected by mutual rotation provided at the second rotating rod 26, so that the output shaft of the driving motor 18, in conjunction with the second rotating block 32 and the transmission belt and the rotating rod B41, can drive the rotating frame 43 to rotate on the outer periphery of the upper end of the rotating disk 42, and push the positioning block 46 to move into the groove 44, thereby realizing the relative separation between the rotating rod A4 and the rotating rod B41, and preventing the second rotating rod 26 from driving the second rotating plate 27 to continue rotating with it, thereby avoiding interference between the movable frame 21 and the limiting slide rail 2, and ensuring that the screen plate 11 can rotate in one direction; on the contrary, when the driving motor 18 drives the second rotating plate 27 to rotate, the positioning block 46 and the positioning slot 45 are re-inserted through the spring 48, so that the second rotating plate 27 can drive the second rotating rod 26 to rotate.

[0033] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
