Description

Technical Field

[0001] The invention relates to the field of bearing production, and in particular to an anti-extrusion device for heat treatment of a bearing ring. Background Art

[0002] Bearing rings need to be heat treated during the production process, and this heat treatment is often carried out in a mesh belt furnace. For example, the patent with application number CN202321983903.7 discloses a mesh belt cleaning device for a mesh belt furnace. Bearing rings are often heat treated in a mesh belt furnace similar to the one in the patent. Before the bearing rings are transferred to the mesh belt furnace, corresponding mechanisms are often required for loading. The existing mesh belt furnace loading mainly relies on manual loading and vibration extrusion feeding by a feeder. However, no matter which method is used, there is mutual squeezing between the bearing rings. After being heated at 840 degrees in a mesh belt furnace, there is thermal expansion. When the bearing rings are squeezed against each other, they cannot expand evenly, and finally the bearing rings become elliptical, and will cause a certain proportion of black skin quality problems during grinding and processing in the next process or at the customer's place. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide an anti-extrusion device for heat treatment of bearing rings, which solves the problems existing in the prior art.

DETAILED DESCRIPTION

[0029] The following will be combined with the attached embodiment of the present invention Figure 1-9 The technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The present invention provides a technical solution: an anti-extrusion device for heat treatment of bearing rings, comprising a transmission mechanism 1, a first stop mechanism 2 and a second stop mechanism 3 are provided on the transmission mechanism 1, a corner transmission structure 4 is provided at the end of the transmission mechanism 1, a material sorting plate 5 is provided at the end of the corner transmission structure 4, a pushing mechanism 6 is provided on the left side of the material sorting plate 5, a lifting mechanism 7 is provided on the right side of the material sorting plate 5, a mesh belt conveyor 8 is provided on the right side of the lifting mechanism 7, a third stop mechanism 9 is provided on the left side of the second stop mechanism 3, and a plurality of air bag blocking mechanisms 10 are provided on the material sorting plate 5. When working, the number of layers of bearing rings stacked is set according to needs. It is assumed here that two layers are stacked, the first layer has two rows of bearing rings, the second layer has one row of bearing rings, and the second layer has one row of bearing rings. The rings are stacked between the two rows of bearing rings on the first layer. The specific working process is as follows: a certain number of bearing rings are conveyed to the transmission mechanism 1 in rows. During this conveying process, the first stop mechanism 2 and the third stop mechanism 9 are open, and the second stop mechanism 3 is in a material blocking state until the entire row of bearing rings enters the transmission mechanism 1. Then the first stop mechanism 2 will start to block the material, and at the same time the third stop mechanism 9 will start and insert into the bearing ring below it to stop it. The bearing ring below the third stop mechanism 9 is the second one from right to left in the entire row of bearing rings on the transmission mechanism 1. In this way, a row of bearing rings between the first stop mechanism 2 and the second stop mechanism 3 is in a ready state. When the preset time is reached, the second stop mechanism 9 will start to block the material. After the bearing ring is released, the second stop mechanism 3 is started and is in the material discharging state, and then the third stop mechanism 9 is started and is in the material discharging state. In this way, the remaining bearing rings on the transmission mechanism are moved to the right by the position of one bearing ring as a whole, and then the third stop mechanism 9 will be started to stop the bearing ring below it, so that the remaining bearing rings on the transmission mechanism 1 are in a ready state again, waiting for the next discharge. When the preset time is reached, the second stop mechanism 3 will be started to release the next bearing ring, and this cycle will be repeated until all the bearing rings on the transmission mechanism 1 are released, and then the airbag blocking mechanism 10 will be restarted to eliminate the obstruction, and then the lifting mechanism 7 will descend until the top surface of the lifting mechanism 7 is flush with the top surface of the material sorting plate 5, and then the pushing mechanism 6 will be started to push a row of bearing rings on the material sorting plate 5 onto the lifting mechanism 7.At this time, the lifting mechanism 7 will rise slightly to the previous state to stop the material. It should be noted here that when the last bearing ring on the transmission frame 1 passes through the second stop mechanism 3, the second row of bearing rings will enter the transmission mechanism 1 and wait like the first row of bearing rings. After that, the second row of bearing rings will be pushed to the top surface of the lifting mechanism 7 like the first row of bearing rings, and arranged side by side with the first row of bearing rings. After that, before the third row of bearing rings on standby on the transmission mechanism 1 are pushed, the lifting mechanism 7 is not lowered to the same level as the material sorting plate 5. The lifting mechanism 7 is not level, but the lifting mechanism 7 descends until the top surface of the bearing ring thereon is flush with the bottom surface of the sorting plate 5, and then the pushing mechanism 6 is started to push the third row of bearing rings to the middle position of the top of the two rows of bearing rings on the top surface of the lifting mechanism 7 for stacking, and then the pushing mechanism 6 returns to its original position, and then the lifting mechanism 7 will rise to be flush with the sorting plate 5, and then the pushing mechanism 6 will push the three rows of bearing rings stacked on the lifting mechanism 7 as a whole onto the mesh belt conveyor 8, and the mesh belt conveyor 8 will transport the bearing rings to the mesh belt furnace for heating, and this cycle is repeated. The present invention uses the method of automatic regular stacking to reserve expansion space for the product in the high-temperature heating state, so that the product expands evenly, reduces ovality, and does not have quality problems such as black skin when grinding in the next process or at the customer, thereby improving the processing efficiency of the next process or at the customer, reducing processing costs, and creating value for customers. Secondly, the method of automatic stacking frees manual loading, reduces the labor intensity of employees, and enables one person to operate multiple devices. Finally, the method of vibrating and pushing materials by the material distribution machine is eliminated to solve the noise generated by the vibration machine. The present invention uses the third stop mechanism 9 and the airbag blocking mechanism 10 to set a good spacing between adjacent bearing rings on the material sorting plate 5, and finally makes them non-contact with each other, which not only prevents the bearing rings from colliding with each other during the transmission process and causing damage, but also separates the adjacent bearing rings so that they do not contact each other, and reserves expansion space for subsequent heat treatment in the mesh belt furnace, so that the heat treatment effect is better. In addition, the setting of the airbag blocking mechanism 10 does not affect the transmission of the bearing rings on the material sorting plate 5 while playing a separation role, nor does it affect the pushing of the pushing mechanism 6. ,

[0031] The transmission mechanism 1 includes a frame 11, on which a transmission belt 12 and a driving structure are provided, the frame 11 includes a front support plate 13 and a rear support plate 14, the first stop mechanism 2 includes a first cylinder 15 fixed on the rear support plate 14, a first telescopic rod 16 of the first cylinder 15 penetrates the rear support plate 14, the second stop mechanism 3 includes a second cylinder 17 fixed on the rear support plate 14, a second telescopic rod 18 of the second cylinder 17 penetrates the rear support plate 14, wherein the first stop mechanism 2 and the second stop mechanism 3 are both set in the form of cylinders, which is not only simple but also has a good stopping effect. The material is blocked by the extension of the first telescopic rod 16 and the second telescopic rod 18, and the material is discharged by the contraction of the first telescopic rod 16 and the second telescopic rod 18.

[0032] The third stop mechanism 9 includes an inverted U-shaped support frame 19 fixed on the frame body 11, and a third cylinder 21 is fixed on the first top plate 20 of the inverted U-shaped support frame 19. The third telescopic rod 22 of the third cylinder 21 penetrates the first top plate 20. When it is necessary to stop the material, the third cylinder 21 is started, and the third telescopic rod 22 is extended until it extends into the inner ring of the bearing ring below it, so that the bearing ring cannot move to the right with the conveyor belt 12, which plays a good stopping role. When it is necessary to release the material, the third cylinder 21 is started, and the third telescopic rod 22 is contracted to release the bearing ring. The third stop mechanism 9 of this structure is not only simple in structure but also has a good stopping effect, and the third telescopic rod 22 is just adapted to the shape of the bearing ring.

[0033] The airbag blocking mechanism 10 includes a groove 23 opened on the material sorting plate 5, the bottom of the groove 23 is provided with a first connecting groove 24 and a second connecting groove 25 connected to the bottom of the material sorting plate 5, an airbag 26 is arranged in the groove 23, the bottom of the airbag 26 is connected with a first connecting pipe 27 and a second connecting pipe 28, the first connecting pipe 27 passes through the first connecting groove 24 and is connected to the air pump 29, the second connecting pipe 28 passes through the second connecting groove 25 and is connected to the air pump 30, the air pump 29 and the air pump 30 are fixed on the fixed plate 31, wherein the airbag blocking mechanism 10 is evenly distributed on the material sorting plate 5, and there is a position for placing a bearing ring between adjacent airbag blocking mechanisms 10, the width of the position can be set to be slightly larger than the outer diameter of the bearing ring, when the bearing ring needs to be blocked, the air pump 29 will be started to quickly inflate the airbag 26, and the inflated airbag 26 will extend out of the groove 23, as shown in FIG. Figure 5As shown, the part of the airbag 26 extending out of the groove 23 will play a role of spacing. When one bearing ring is transferred to the material sorting plate 5, the airbag blocking mechanism 10 on the front side will be activated to separate it, and this will continue until all the bearing rings on the transmission mechanism 1 are transferred to the material sorting plate 5. At this time, all the airbags 26 are in a state of being inflated and extending out of the groove 23. After that, all the vacuum pumps 30 are started at the same time to evacuate the airbags 26 until the airbags 26 are pumped into the retracted groove 23. In this way, space is left between adjacent bearing rings for subsequent heat treatment expansion, and at the same time, it does not affect the transmission of the bearing rings and the pushing of the pushing mechanism 6.

[0034] The corner transmission structure 4 includes a first curved plate 32 and a second curved plate 33. The first curved plate 32 is connected to the rear support plate 14, and the second curved plate 33 is connected to the front support plate 13. An arc slide 34 is fixed between the first curved plate 32 and the second curved plate 33. The end of the arc slide 34 close to the conveyor belt 12 is higher than the end away from the conveyor belt 12. Through the setting of this structure, the bearing ring on the transmission mechanism 1 will slide onto the material sorting plate 5 through the arc slide 34 without the aid of other conveying mechanisms. This not only saves costs, but also has a good transmission effect. When the arc slide 34 is set, the bearing ring on the transmission mechanism 1 can slide to the rearmost end of the material sorting plate 5.

[0035] The pushing mechanism 6 includes a pushing plate 35 arranged on the left side of the material sorting plate 5, and a fourth telescopic rod 37 of a fourth cylinder 36 is fixed on the left side surface of the pushing plate 35, and the fourth cylinder 36 is fixed on the support frame 38. Guide seats 39 are provided on the front and rear sides of the fourth cylinder 36, and a guide rod 40 runs through the guide seat 39. The right end of the guide rod 40 is fixed on the left side surface of the pushing plate 35, and the guide seat 39 is fixed on the support frame 38. This is the specific structure of the pushing mechanism 6, and the pushing plate 35 is driven by the fourth cylinder 36 to push the material, wherein the setting of the guide seat 39 and the guide rod 40 not only plays the role of guiding and limiting, but also makes the whole row of bearing rings evenly stressed when pushing the bearing rings, thereby making the pushing effect better and more stable.

[0036] The lifting mechanism 7 includes a lifting plate 41 arranged on the right side of the material sorting plate 5, an inverted U-shaped support seat 42 is arranged below the lifting plate 41, a through-shaft screw stepper motor 43 is fixed on the inverted U-shaped support seat 42, a screw 44 is passed through the through-shaft screw stepper motor 43, the top of the screw 44 is fixed on the bottom surface of the lifting plate 41, and the lower end of the screw 44 passes through the second top plate 45 of the inverted U-shaped support seat 42. This is the specific structure of the lifting mechanism 7, and the lifting and lowering of the lifting plate 41 is realized by the through-shaft screw stepper motor 43 and the screw 44. The through-shaft screw stepper motor 43 and the screw 44 can also be replaced by a cylinder to realize lifting and lowering.

[0037] Through holes 46 are provided on the left and right sides of the second top plate 45, and a shaft sleeve 47 is fixed in the through hole 46. A guide shaft 48 is sleeved in the shaft sleeve 47. The top end of the guide shaft 48 is fixed to the bottom surface of the lifting plate 41, and a limiting block 49 is fixed to the lower end of the guide shaft 48. The arrangement of the shaft sleeve 47 and the guide shaft 48 not only plays a good guiding role, but also makes the entire lifting mechanism 7 more stable.

[0038] The mesh belt conveyor 8 is arranged on the fixed frame 50, and a connecting plate 51 is arranged between the mesh belt conveyor 8 and the lifting plate 41, and the connecting plate 51 is fixed on the fixed frame 50. The setting of the connecting plate 51 facilitates pushing the bearing ring onto the mesh belt conveyor 8, and the connecting plate 51 plays a good connecting role, wherein the material sorting plate 5 and the fixed plate 31 are also arranged on the fixed frame 50.

[0039] A layer of flexible pad 52 is fixed to the inner surface of the first arc plate 32 and the second arc plate 33, wherein the flexible pad 52 can be made of sponge material, foam material, rubber material, etc. Through the setting of the flexible pad 52, the bearing ring can be prevented from being bumped and damaged by the first arc plate 32 or the second arc plate 33 when passing through the corner transmission structure 4.

[0040] Working principle: During operation, the number of layers of bearing rings stacked is set according to specific needs. Here, it is assumed that two layers are stacked, the first layer has two rows of bearing rings, the second layer has one row of bearing rings, and the row of bearing rings on the second layer is stacked between the two rows of bearing rings on the first layer. The specific working process is as follows: A certain number of bearing rings are conveyed to the transmission mechanism 1 in rows. During this conveying process, the first stop mechanism 2 and the third stop mechanism 9 are open, and the second stop mechanism 3 is in a blocking state until the entire row of bearing rings enters the transmission mechanism 1. After that, the first stop mechanism 2 will start to block the material, and at the same time, the third stop mechanism 9 will start and insert into the bearing ring below it to stop it. The bearing ring below the third stop mechanism 9 The ring is the second one from right to left in the whole row of bearing rings on the transmission mechanism 1, so that a row of bearing rings between the first stop mechanism 2 and the second stop mechanism 3 is in a ready state. When the preset time is reached, the second stop mechanism 3 will be started and in a discharging state, and a bearing ring on the left side of the second stop mechanism 3, that is, the first bearing ring from the right in the whole row of bearing rings on the transmission mechanism 1 will be released. The released bearing ring is transmitted to the material sorting plate 5 through the corner transmission structure 4. At this time, the top surface of the lifting mechanism 7 is in a state slightly higher than the material sorting plate 5, which can prevent the bearing ring from sliding out of the material sorting plate 5 to the right. After the bearing ring slides to the rear end of the material sorting plate 5, its front side airbag blocking mechanism 10 will start blocking to play a spacing role. Used to space the bearing ring from the next bearing ring entering the sorting plate 5; after the bearing ring is released, the second stop mechanism 3 is started and is in the blocking state, and then the third stop mechanism 9 will be started and in the discharging state, so that the remaining bearing rings on the transmission mechanism are moved to the right as a whole by the position of one bearing ring, and then the third stop mechanism 9 will be started to stop the bearing ring below it, so that the remaining bearing rings on the transmission mechanism 1 are in a ready state again, waiting for the next discharging, and when the preset time is reached, the second stop mechanism 3 will be started to release the next bearing ring, and it will be repeated in this way until all the bearing rings on the transmission mechanism 1 are released, and then the airbag blocking mechanism 10 is restarted The lifting mechanism 7 moves to eliminate the obstruction, and then the lifting mechanism 7 will descend until the top surface of the lifting mechanism 7 is flush with the top surface of the material sorting plate 5, and then the pushing mechanism 6 will start to push a row of bearing rings on the material sorting plate 5 onto the lifting mechanism 7. At this time, the lifting mechanism 7 will rise slightly to the previous state to block the material. It should be noted here that when the last bearing ring on the transmission frame 1 passes through the second stop mechanism 3, a second row of bearing rings will enter the transmission mechanism 1 for standby like the first row of bearing rings, and then the second row of bearing rings will be pushed to the top surface of the lifting mechanism 7 like the first row of bearing rings, and arranged side by side with the first row of bearing rings. After that, the third row of bearing rings on standby on the transmission mechanism 1 are pushed before the material is pushed.The lifting mechanism 7 does not descend to be flush with the material sorting plate 5, but the lifting mechanism 7 descends until the top surface of the bearing ring thereon is flush with the bottom surface of the material sorting plate 5, and then the pushing mechanism 6 is started to push the third row of bearing rings to the middle position of the top of the two rows of bearing rings on the top surface of the lifting mechanism 7 for stacking, and then the pushing mechanism 6 returns to its original position, and then the lifting mechanism 7 will rise to be flush with the material sorting plate 5, and then the pushing mechanism 6 will push the three rows of bearing rings stacked on the lifting mechanism 7 as a whole onto the mesh belt conveyor 8, and the mesh belt conveyor 8 will transport the bearing rings to the mesh belt furnace for heating, and this cycle is repeated. The present invention uses the method of automatic regular stacking to reserve expansion space for the product in the high-temperature heating state, so that the product expands evenly, reduces ovality, and does not have quality problems such as black skin when grinding in the next process or at the customer, thereby improving the processing efficiency of the next process or at the customer, reducing processing costs, and creating value for customers. Secondly, the method of automatic stacking frees manual loading, reduces the labor intensity of employees, and enables one person to operate multiple devices. Finally, the method of vibrating and pushing materials by the material distribution machine is eliminated to solve the noise generated by the vibration machine. The present invention uses the third stop mechanism 9 and the airbag blocking mechanism 10 to set a good spacing between adjacent bearing rings on the material sorting plate 5, and finally makes them non-contact with each other, which not only prevents the bearing rings from colliding with each other during the transmission process and causing damage, but also separates the adjacent bearing rings so that they do not contact each other, and reserves expansion space for subsequent heat treatment in the mesh belt furnace, so that the heat treatment effect is better. In addition, the setting of the airbag blocking mechanism 10 does not affect the transmission of the bearing rings on the material sorting plate 5 while playing a separation role, nor does it affect the pushing of the pushing mechanism 6. ,
