Description

Technical Field

[0001] The invention relates to a shaping device, in particular to a shaping device used for bearings after heat treatment, and belongs to the technical field of bearing heat treatment. Background Art

[0002] Bearings are an important component in current mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Their structure is relatively simple and is generally composed of an outer ring, an inner ring, steel balls, and a cage. During the heat treatment process of the bearings, due to the narrow width and thin wall of some bearing rings, the products may have excessive bending of the rings during the heat treatment process. Therefore, excessive bending of the rings will seriously affect the processing accuracy of the products. In order to avoid waste of these defective bearing rings, a shaping device is usually used to repair the defective bearing rings to reduce the production cost of the bearings.

[0003] In the prior art, multiple shaping devices are required to be used in the process of shaping the bearing rings after heat treatment. Since the bearing rings need to be placed in a heating furnace for heating during the heat treatment process to soften the bearing rings, the bearing rings are taken out of the heating furnace after heat treatment, and then multiple shaping devices are used to shape the bearing rings in turn, which takes a long time. As a result, the temperature of the bearing rings themselves drops, resulting in hardening of the texture. Subsequent shaping devices need to spend even longer time to shape the bearing rings, thereby reducing the shaping efficiency of the bearing rings, resulting in the device being unable to adapt to large-scale bearing ring shaping work. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to provide a reshaping device for bearings after heat treatment.

[0010] Optionally, a groove is provided inside the two extrusion rings, and a plurality of second electric telescopic rods are installed inside the two grooves.

[0014] Optionally, a fourth electric telescopic rod is installed at the bottom of the two moving rods, and a connecting plate is installed at the telescopic ends of the two fourth electric telescopic rods. A semicircular loading plate is installed on the outer wall of the two connecting plates on the side close to each other through a rotating shaft, and two sliding plates with inclined surfaces on one side are slidably installed at the bottom ends of the two loading plates.

[0015] Optionally, two telescopic rods are installed inside one end of the two connecting plates close to the loading plate, and the telescopic ends of the two telescopic rods extend to the inside of the loading plate.

[0016] The beneficial effects of the present invention are:

[0017] 1. In the present invention, the first fixing mechanism is provided to quickly limit and fix the bearing ring that needs to be shaped, and in the process of the two extrusion rings extruding and shaping the bearing ring, the second electric telescopic rod can push the two protective plates to extend and be sleeved on the outer wall of the bearing ring, which can slow down the cooling speed of the bearing ring after heat treatment, and facilitate the two extrusion rings to cooperate with each other to extrude and shape the deformation defects at the upper and lower ends of the bearing ring; and the two protective plates can also support the outer wall of the bearing ring, avoiding the problem of the outer wall of the bearing ring being deformed again after the upper and lower ends of the bearing ring are squeezed, thereby improving the effect of shaping the bearing ring.

[0018] 2.

[0019] 3. In this invention, after the curved outer wall and the upper and lower ends of the bearing ring are extruded and shaped, two clamping plates clamp and fix the bearing ring, and the driving motor can be controlled to drive multiple components such as the curved plate and the extrusion ring to rotate together. The multiple rotating curved plates can grind and polish the inner wall of the bearing ring, and the extrusion rings located at the upper and lower ends of the bearing ring can grind and polish its upper and lower ends, thereby further improving the shaping effect of the bearing ring surface.

[0020] 4. In this invention, after the inner wall and the upper and lower ends of the bearing ring are polished, the bearing ring is individually limited and fixed by a first fixing mechanism, and then the two clamping plates are controlled to fit the outer wall of the bearing ring. While the driving motor drives the multiple arc-shaped plates to rotate, it can also drive the bearing ring itself to rotate. During the rotation, the bearing ring contacts the outer wall on the side close to the two clamping plates, thereby polishing the arc-shaped outer wall of the bearing ring, achieving the effect of polishing the inner and outer arc-shaped outer walls and the upper and lower flat outer walls of the bearing ring.

DETAILED DESCRIPTION

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 7 A device for shaping a bearing after heat treatment comprises a base 1 and a bearing ring 16. A shell 2 is installed in the center of the top of the base 1. The bearing ring 16 is arranged above the shell 2. A first fixing mechanism for fixing the bearing ring 16 is installed on the top of the shell 2. Two fixing plates 3 are symmetrically installed on the top of the base 1. A second fixing mechanism for assisting the fixation of the bearing ring 16 is installed on the outer wall of the side close to each other of the two fixing plates 3. A feeding mechanism for assisting the bearing ring 16 to be fitted on the surface of the first fixing mechanism is installed on the top of the two fixing plates 3.

[0032] As a technical optimization solution of the present invention, the first fixing mechanism includes a fixing rod 15, a circular plate 14 is rotatably mounted on the top of the housing 2, the bottom end of the fixing rod 15 is mounted on the top of the circular plate 14, and the four outer walls of the fixing rod 15 are each mounted with a first electric telescopic rod 19. The telescopic ends of the multiple first electric telescopic rods 19 are each connected to an arc-shaped plate 12, and the outer walls of the multiple arc-shaped plates 12 are each in contact with the inner wall of the bearing ring 16. After the bearing ring 16 is fitted over the outer walls of the multiple arc-shaped plates 12, the telescopic ends of the multiple first electric telescopic rods 19 are controlled to extend, driving the multiple arc-shaped plates 12 to move away from the fixing rod 15, so that the outer walls of the multiple arc-shaped plates 12 are in close contact with the inner wall of the bearing ring 16, thereby completing the limited fixation of the bearing ring 16.

[0033] As a technical optimization solution of the present invention, a drive motor 13 is installed inside the housing 2, and the output end of the drive motor 13 is connected to the bottom end of the circular plate 14. After starting, the drive motor 13 can drive the circular plate 14 and the fixing rod 15 mounted on the top of the circular plate 14 to rotate synchronously, thereby driving the multiple curved plates 12 to rotate together.

[0034] As a technical optimization solution of the present invention, two extrusion rings 10 are collectively mounted on the outer walls of the multiple curved plates 12. The two extrusion rings 10 are respectively located at the upper and lower ends of the bearing ring 16. The outer walls of the multiple curved plates 12 are each provided with a guide groove 18, and the inner walls of the two extrusion rings 10 are each provided with a protrusion 17 that matches the multiple guide grooves 18. The two extrusion rings 10 can be inserted and matched with the guide grooves 18 on the outer walls of the curved plates 12 via the protrusions 17 provided on the inner walls. Placing the bearing ring 16 between the two extrusion rings 10 can extrusion and shape the upper and lower ends of the bearing ring 16.

[0035] As a technical optimization solution of the present invention, both extrusion rings 10 are internally defined with grooves 20, each of which houses multiple second electric telescopic rods 21. The telescopic ends of the multiple second electric telescopic rods 21 are collectively connected to a protective plate 22 that abuts the outer wall of the bearing ring 16. Both protective plates 22 are coated with a thermal insulation material. During the process of extrusion and shaping the bearing ring 16 by the two extrusion rings 10, the telescopic ends of the multiple second electric telescopic rods 21 can be controlled to extend, pushing the protective plates 22 against the surface of the bearing ring 16. This prevents the bearing ring 16 from cooling too quickly, which would make subsequent extrusion and shaping by the extrusion rings 10 more difficult.

[0036] As a technical optimization solution of the present invention, the second fixing mechanism includes two mounting plates 9. Multiple third electric telescopic rods 8 are mounted on the outer walls of the adjacent sides of the two fixing plates 3. The telescopic ends of the multiple third electric telescopic rods 8 are connected to the adjacent mounting plates 9. When the telescopic ends of the multiple third electric telescopic rods 8 extend, they push the two mounting plates 9 toward each other.

[0037] As a technical optimization solution of the present invention, the outer walls of the adjacent sides of the two mounting plates 9 are each provided with a clamping plate 11 that is adapted to the outer wall of the bearing ring 16. A sliding groove 24 is provided inside each mounting plate 9. A screw 23 that is adapted to the sliding groove 24 is installed on the distal end of each of the two clamping plates 11. Nuts are threadedly installed on the ends of the two screws 23 that are distal to the clamping plates 11. The clamping plates 11 can pass through the sliding groove 24 through the screw 23 provided at one end, and then the screw 23 is fixed in position using a nut, thereby completing the installation of the clamping plates 11. The two mating clamping plates 11 can limit and fix the curved outer wall of the bearing ring 16, so that while the drive motor 13 drives the multiple curved plates 12 to rotate, it cannot drive the bearing ring 16 to continue rotating.

[0038] As a technical optimization solution of the present invention, the feeding mechanism includes a rectangular groove 4 opened on the outer wall of one side of two fixed plates 3. A screw rod 5 is rotatably mounted inside each rectangular groove 4, and a movable rod 6 is mounted on the outer wall of each screw rod 5 to cooperate with it. A driving device connected to one end of the screw rod 5 is pre-installed inside each fixed plate 3. When the driving device is activated, it can drive the screw rod 5 to rotate forward and reverse inside the rectangular groove 4, thereby driving the movable rod 6 to move up and down inside the rectangular groove 4 to adjust its position.

[0039] As a technical optimization solution of the present invention, a fourth electric telescopic rod 25 is installed at the bottom of each of the two movable rods 6. A connecting plate 26 is installed at the telescopic ends of each of the four electric telescopic rods 25. A semicircular loading plate 7 is installed on the outer wall of the two connecting plates 26 on the side close to each other through a rotating shaft. Two sliding plates 28 with inclined surfaces on one side are slidably installed at the bottom of each of the two loading plates 7. A driving device is pre-installed inside each of the two loading plates 7. After startup, the driving device can drive the loading plates 7 to rotate and adjust via the rotating shaft. The telescopic ends of the two fourth electric telescopic rods 25 are rotatably connected to the connecting plate 26, which can drive the connecting plate 26 and the loading plate 7 to rotate horizontally. Both sliding plates 28 can be moved by a pre-installed pushing mechanism at the bottom of the loading plate 7, so that the ends of the two sliding plates 28 with inclined surfaces move close to the inner wall of the loading plate 7, thereby facilitating the placement of the bearing ring 16 on top of the sliding plate 28.

[0040] As a technical optimization solution of the present invention, two telescopic rods 27 are installed inside the ends of the two connecting plates 26 close to the loading plate 7. The telescopic ends of the two telescopic rods 27 extend into the interior of the loading plate 7. The two telescopic rods 27 can limit and fix the position of the loading plate 7 after the telescopic ends extend into the interior of the loading plate 7.

[0041] In the present invention, when the user uses the device, after the bearing ring 16 has been heat treated, if it is found that part of the bearing ring 16 surface is deformed and needs to be reshaped using the device, the telescopic ends of the multiple first electric telescopic rods 19 are all in a retracted state, driving the multiple arc plates 12 at this time to move to a position close to the fixed rod 15, and one of the extrusion rings 10 can be first sleeved on the surface of the multiple arc plates 12, so that there is a gap between the inner wall of the extrusion ring 10 located on the surface of the multiple arc plates 12 and the outer wall of the multiple arc plates 12, and the end of the protrusion 17 away from the extrusion ring 10 is not completely inserted into the guide groove 18 on the surface of the multiple arc plates 15, but at this time the extrusion ring 10 can still slide down to the top of the circular plate 14 with the help of the insertion and cooperation of the protrusion 17 and the guide groove 18, and then the bearing ring 16 to be shaped is transferred to the inside of the two loading plates 7 by the grabbing mechanical equipment and placed on the top of the sliding plate 28.

[0042] Then, the driving device inside the two fixed plates 3 can be controlled to start, driving the two screw rods 5 to rotate synchronously inside the rectangular groove 4, thereby driving the two moving rods 6 and the two loading plates 7 to move downward together, driving the bearing ring 16 to slowly move downward on the outer wall of the multiple curved plates 12 until the bottom surface of the bearing ring 16 contacts the top surface of the extrusion ring 10 below, and controlling the telescopic ends of the multiple first electric telescopic rods 19 on the outer wall of the fixed rod 15 to extend, pushing the multiple curved plates 12 to move in the direction away from the fixed rod 15, so that the multiple curved plates 12 The outer wall is in close contact with the inner wall of the bearing ring 16 and the extrusion ring 10, and then the telescopic ends of the multiple third electric telescopic rods 8 are controlled to extend, pushing the two mounting plates 9 and the clamping plates 11 to move towards each other until the two clamping plates 11 are completely in contact with the outer wall of the bearing ring 16. Since the arc-shaped surfaces of the two clamping plates 11 are close to each other and adapt to the arc-shaped outer wall of the bearing ring 16, the two clamping plates 11 are in close contact with the outer wall of the bearing ring 16, and the deformed outer wall of the bearing ring 16 can be squeezed and shaped to achieve the effect of shaping the outer wall of the bearing ring 16.

[0043] After the outer wall of the bearing ring 16 is shaped, the two loading plates 7 are controlled to reset upward, and another extrusion ring 10 is placed on the top of the multiple arc plates 12 and slowly moved downward to the top of the bearing ring 16 to avoid the bearing ring 16 and the extrusion ring 10 colliding and causing more serious deformation. At this time, the two extrusion rings 10 are respectively located at the upper and lower ends of the bearing ring 16, and the telescopic ends of the multiple third electric telescopic rods 8 can be controlled to retract, driving the two clamping plates 11 to move to Figure 2In the state shown, the telescopic ends of the multiple second electric telescopic rods 21 are controlled to extend, driving the two protective plates 22 to extend from the inside of the extrusion ring 10 and to be sleeved on the outer wall of the bearing ring 16. Since the surfaces of the two protective plates 22 are provided with heat-insulating materials, after the two protective plates 22 cooperate to enclose the outer wall of the bearing ring 16, the cooling speed of the heat-treated bearing ring 16 can be slowed down, so that the hardness of the bearing ring 16 itself has not yet recovered. At this time, the two moving rods 6 and the loading plate 7 can be driven to move downward slowly by the rotation of the two screw rods 5 to extrude the extrusion ring 10 at the upper end downward, so that the two extrusion rings 10 can cooperate with each other to extrude the deformation defects at the upper and lower ends of the bearing ring 16. The two protective plates 22 located on the outer wall of the bearing ring 16 can also support the outer wall of the bearing ring 16, avoiding the problem of the outer wall of the bearing ring 16 being deformed again after the upper and lower ends of the bearing ring 16 are squeezed, thereby improving the shaping effect of the bearing ring 16; due to the high height of the two mounting plates 9 and the long length of the slide groove 24, multiple clamping plates 11 can be installed on the inside of the mounting plate 9 through screws 23 and nuts according to actual usage requirements, and multiple extrusion rings 10 and bearing rings 16 can be sequentially installed on the outer walls of multiple arc plates 12, so that multiple bearing rings 16 with defects after heat treatment can be shaped, thereby improving the shaping efficiency of the entire device for large quantities of bearing rings 16.

[0044] After the arc-shaped outer wall and the upper and lower ends of the bearing ring 16 are extruded and shaped, the bearing ring 16 will still have a small amount of impurities and black spots due to the heat treatment, which will affect the glossiness and aesthetics of the surface of the bearing ring 16. At this time, the telescopic ends of the multiple second electric telescopic rods 21 can be controlled to retract, driving the two protective plates 22 to retract to the inside of the groove 20. The two loading plates 7 are still located on the top of the extrusion ring 10 above, pressing and fixing the extrusion ring 10, and then controlling the telescopic ends of the multiple third electric telescopic rods 8 to extend again, driving the two clamping plates 11 to clamp and fix the bearing ring 16 in the direction of approaching each other. , then the drive motor 13 can be controlled to start, driving the circular plate 14, the fixing rod 15 and the multiple curved plates 12 to rotate together. Since the two extrusion rings 10 are clamped with the guide groove 18 through the protrusion 17, the two extrusion rings 10 can be driven to rotate together, and the outer wall of the bearing ring 16 is clamped and fixed by two matching clamping plates 11, so that the bearing ring 16 cannot rotate automatically. The multiple rotating curved plates 12 can grind and polish the inner wall of the bearing ring 16, and the extrusion rings 10 located at the upper and lower ends of the bearing ring 16 can grind and polish its upper and lower ends, thereby further improving the shaping effect of the surface of the bearing ring 16.

[0045] After the inner wall and the upper and lower ends of the bearing ring 16 are polished, the two extrusion rings 10 can be removed from the outer walls of the multiple curved plates 12, and the telescopic ends of the multiple first electric telescopic rods 19 are controlled to extend, driving the outer walls of the multiple curved plates 12 to closely abut against the inner wall of the bearing ring 16, so that the position of the bearing ring 16 on the outer wall of the curved plate 12 is fixed. At this time, the two clamping plates 11 can be controlled to fit with the outer wall of the bearing ring 16. When the driving motor 13 drives the multiple curved plates 12 to rotate, it can also drive the bearing ring 16 itself to rotate, and the bearing ring 16 is in the process of rotation. The outer wall of the side close to the two plywood 11 is in contact, so that the curved outer wall of the bearing ring 16 can be ground and polished, and the curved outer walls on both sides of the inner and outer sides and the upper and lower plane outer walls of the bearing ring 16 can be ground and polished; and after the horizontal grinding and polishing of the bearing ring 16 itself rotating and rubbing against the two plywood 11 is completed, the protective plate 22 can be pushed up and down repeatedly by controlling the telescopic ends of multiple second electric telescopic rods 21, so that the curved outer wall of the bearing ring 16 can be vertically ground and polished, thereby improving the grinding and polishing effect of the curved outer wall of the bearing ring 16.

[0046] Since some of the bearing rings 16 have chamfers at the upper and lower ends, it is impossible to polish and reshape the defects of the chamfers of the bearing rings 16 using two clamping plates 11. Please refer to Figure 2 As shown, at this time, the telescopic ends of the two telescopic rods 27 inside one of the connecting plates 26 can be controlled to retract, and one of the loading plates 7 can be driven to rotate 180 degrees by the preset driving device inside the connecting plate 26. Then, the telescopic ends of the two telescopic rods 27 are controlled to extend and be inserted into the inside of the loading plate 7, and the loading plate 7 after the position change is limited and fixed, so that one of the loading plates 7 is located at the top end of the bearing ring 16, and the other loading plate 7 is driven downward to the bottom end of the bearing ring 16 by the extension of the telescopic end of the fourth electric telescopic rod 25, and the multiple sliding plates 28 are controlled to slide out with one end of the inclined surface so that the inclined surface of the sliding plate 28 abuts against the chamfered positions at the upper and lower ends of the bearing ring 16. At this time, the driving motor 13 drives the multiple arc plates 12 and the bearing ring 16 to rotate, and the chamfered positions of the bearing ring 16 abut against the inclined surface of the sliding plate 28, thereby achieving the effect of grinding and polishing the chamfered positions at the upper and lower ends of the bearing ring 16, and realizing the effect of comprehensive shaping of the surface of the bearing ring 16.

[0047] After the shaping work of the bearing ring 16 is completed, the two rotating screw rods 5 can also drive the moving rod 6 and the loading plate 7 to move downward to the outside of the bearing ring 16, and control the multiple sliding plates 28 to extend one end with the inclined surface toward the bottom of the bearing ring 16, so that the bottom of the bearing ring 16 is placed on the top of the multiple sliding plates 28. The loading plate 7 is driven downward by the reversal of the screw rod 5, and then the shaped bearing ring 16 is driven to move upward together until the bearing ring 16 is separated from the multiple arc plates 12, and the shaped bearing ring 16 can be automatically picked up and transported again by the grasping mechanical equipment.
