Description
Technical Field
[0001] The utility model belongs to the technical field of wire race bearing processing, and particularly relates to a processing tooling for wire race. Background Art
[0002] The wire race bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. During the processing of the wire race shaft, the position is fixed through the tooling.
[0003] Currently, wire race assembled bearings can be seen in China. However, during the production of wire races, the processing accuracy of the equipment is low, which will affect the efficiency of subsequent processes. The conventional arc shaping process uses three rollers with the same diameter. The outer circumferential surface of the roller directly extrudes the wire, which easily damages the outer diameter arc of the wire, resulting in the scrapping of the raw material. Moreover, the wire is prone to rebound, and the flatness and roundness of the rolled finished product are poor, unable to meet the use requirements. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a processing tooling for wire race, which is not easy to damage the wire and can improve the processing accuracy of the wire race.
[0005] To achieve the above purpose, the solution of the utility model is: a processing tooling for wire race, including a bracket, a coiling disc, a trimmer, a conveying device, two pressing rollers and a pressing device;
[0006] The coiling disc is rotatably arranged on the bracket, and a first groove matching with the inner circumference of the wire race is arranged on the outer circumferential surface of the coiling disc;
[0007] The two pressing devices are both arranged on the bracket along the diameter direction of the coiling disc. The end of the pressing device facing the coiling disc is the pressing end, and a pressing roller is rotatably arranged on the pressing end. The pressing device makes the pressing roller press and cooperate with the outer circumference of the coiling disc. A second groove matching with the outer circumference of the wire race is arranged on the outer circumferential surface of the pressing roller. The second groove and the first groove are correspondingly arranged to form a coiling channel;
[0008] The trimmer is arranged on one side of the coiling disc. A trimming channel corresponding to the coiling channel is arranged in the trimmer. The conveying device is arranged on one side of the trimmer to drive the wire to pass through the trimming channel into the coiling channel.
[0009] Further, the pressing device includes an adjusting block and a pressing rod. The adjusting block is fixed on the bracket. One end of the pressing rod is movably arranged on the adjusting block, and the other end of the pressing rod is the pressing end. The pressing rod moves towards the coiling disc along the diameter direction of the coiling disc to make the pressing roller press and cooperate with the outer circumference of the coiling disc.
[0010] Further, the pressure rod is driven by a telescopic air cylinder or an electric push rod, or the pressure rod is threadedly connected to the adjustment block.
[0011] Further, the pressing device includes an adjustment block and a pressure rod. The adjustment block is movably arranged on the bracket. One end of the pressure rod is fixedly arranged on the adjustment block, and the other end of the pressure rod is the pressing end. The adjustment block moves along the diameter direction of the coiling disc towards the coiling disc so that the pressing roller is pressed and fitted on the outer periphery of the coiling disc.
[0012] Further, the adjustment block is driven by a telescopic air cylinder or an electric push rod to move along the diameter direction of the coiling disc.
[0013] Further, the trimming channel corresponds to the feeding end of the coiling channel, and a cutter for cutting off the steel wire is movably arranged at the discharging end of the coiling channel.
[0014] Further, a plurality of driving rollers are arranged between the conveying device and the trimmer. A third groove for cooperating with the steel wire is arranged on the outer peripheral surface of the driving roller. The third grooves between the plurality of driving rollers form a driving channel. The driving channel is aligned with the trimming channel. The steel wire sequentially passes through the driving channel and the trimming channel into the coiling channel.
[0015] Further, the conveying device is a rotatably arranged wire unwinding reel. The wire unwinding reel is wound with the steel wire, and the wire unwinding reel is rotated to unwind the steel wire.
[0016] After adopting the above scheme, the beneficial effects of the utility model are as follows:
[0017] In the utility model, two pressing rollers are arranged on the outer periphery of the coiling disc. The pressing rollers are pressed and fitted on the outer periphery of the coiling disc through the pressing device. A first groove for cooperating with the inner periphery of the wire raceway is arranged on the outer peripheral surface of the coiling disc, and a second groove for cooperating with the outer periphery of the wire raceway is arranged on the outer peripheral surface of the pressing roller. The first groove and the second groove correspondingly form a coiling channel. Thus, when coiling, the steel wire will be restricted in the coiling channel and is not easily crushed and damaged to the raw material. Moreover, the pressing device is arranged along the diameter direction of the coiling disc and enables the pressing rollers to be pressed and fitted on the outer periphery of the coiling disc, so that the wire raceway can be coiled into shape, the steel wire is not easy to rebound, the flatness and roundness of the coiled finished product are relatively high, and the diameter of the wire raceway is the same as that of the coiling disc. Different diameter coiling discs can be replaced to process wire raceways of different diameters. In addition, before the steel wire enters the coiling channel, it first passes through the trimming channel. The trimming channel can trim the steel wire to make the steel wire smoother and the shape more complete, so as to reduce the error of the wire raceway. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will describe the present utility model in detail with reference to the accompanying drawings and specific embodiments.
[0024] As Figures 1-3 shown, the present utility model provides a processing tool for a steel wire raceway, including a bracket 1, a coiling disc 2, a trimmer 3, a conveying device 4, two pressing rollers 5 and a pressing device 6; the coiling disc 2 is rotatably arranged on the bracket 1, the bracket 1 can be a support plate or other support frame structures, and a first groove 21 for cooperating with the inner circumference of the steel wire raceway is provided on the outer circumferential surface of the coiling disc 2; the two pressing devices 6 are both arranged on the bracket 1 along the diameter direction of the coiling disc 2, and the end of the pressing device 6 facing the coiling disc 2 is the pressing end 621, and a pressing roller 5 is rotatably arranged on the pressing end 621. The pressing device 6 can press the pressing roller 5 against the outer circumference of the coiling disc 2. A second groove 51 for cooperating with the outer circumference of the steel wire raceway is provided on the outer circumferential surface of the pressing roller 5. The second groove 51 is correspondingly arranged with the first groove 21 to form a coiling channel. The steel wire 7 is conveyed into the coiling channel by the conveying device 4. At the same time, the coiling disc 2 is started to rotate. The coiling disc 2 will drive the two pressing rollers 5 to rotate, and the pressing device 6 presses the pressing rollers 5 against the outer circumference of the coiling disc 2, so that the steel wire 7 must pass through the coiling channel, realizing coiling and forming. The steel wire 7 is not easy to rebound, and the flatness and roundness of the coiled finished product are relatively high. Moreover, the diameter of the steel wire raceway is the same as that of the coiling disc 2. Different diameter coiling discs 2 can be replaced to process steel wire raceways with different diameters.
[0025] The trimmer 3 is arranged on one side of the coiling disc 2, and the conveying device 4 is arranged on one side of the trimmer 3, that is, the trimmer 3 is arranged between the conveying device 4 and the coiling disc 2. A trimming channel 31 corresponding to the coiling channel is provided in the trimmer 3. The conveying device 4 first drives the steel wire 7 to pass through the trimming channel 31 and then enters the coiling channel for coiling. The steel wire 7 passes through the trimming channel 31 before entering the coiling channel. The trimming channel 31 can trim the steel wire 7 into the required shape, making the steel wire 7 smoother and the shape more complete, so as to reduce the error of the steel wire raceway and improve the processing accuracy of the steel wire raceway bearing.
[0026] For key reference Figure 1 and Figure 2 , the pressing device 6 includes an adjusting block 61 and a pressing rod 62. In one embodiment, the adjusting block 61 is fixed on the bracket 1, one end of the pressing rod 62 is movably arranged on the adjusting block 61, the other end of the pressing rod 62 is a pressing end 621, and the pressing rod 62 moves towards the coiling disc 2 along the diameter direction of the coiling disc 2. Until the pressing roller 5 is fitted on the outer periphery of the coiling disc 2, the pressing rod 62 stops moving, so as to press and fit the pressing roller 5 on the outer periphery of the coiling disc 2, thereby limiting the steel wire 7 in the coiling channel, making the steel wire 7 not easy to rebound, improving the flatness and roundness of coiling, and moreover, different thicknesses of steel wire 7 can be processed by moving the pressing rod 62, and it is also convenient to replace coiling discs 2 with different diameters. The pressing rod 62 can be driven by a telescopic cylinder or an electric push rod to move along the diameter direction of the coiling disc 2, or the pressing rod 62 itself is a telescopic cylinder or an electric push rod structure. In addition, Figure 2 and Figure 3 in the shown embodiment, the pressing rod 62 is threadedly connected to the adjusting block 61, and rotating the pressing rod 62 can drive the pressing rod 62 to move along the diameter direction of the coiling disc 2. Of course, other ways can also be used to drive the pressing rod 62 to move, and this embodiment is not limited.
[0027] In another embodiment, the adjusting block 61 is movably arranged on the bracket 1, one end of the pressing rod 62 is fixedly arranged on the adjusting block 61, the other end of the pressing rod 62 is a pressing end 621, and moving the adjusting block 61 along the diameter direction of the coiling disc 2 can also drive the pressing roller 5 to be pressed and fitted on the outer periphery of the coiling disc 2. The adjusting block 61 can be specifically driven by a telescopic cylinder or an electric push rod to move along the diameter direction of the coiling disc 2, or can be driven by other driving mechanisms, and this embodiment is not limited.
[0028] Further, the trimming channel 31 corresponds to the feeding end of the coiling channel, that is, the trimmer 3 is located on one side of one of the pressing rollers 5. A cutter 8 for cutting off the steel wire 7 is movably arranged at the discharging end of the coiling channel, that is, the cutter 8 and the trimmer 3 are arranged on both sides of the coiling disc 2. When the steel wire 7 is coiled into a ring, the cutter 8 cuts off the steel wire 7 at the discharging end of the coiling channel, that is, the coiling process of one steel wire raceway is completed. The cutter 8 is movably arranged on the bracket 1 and can also be driven by a telescopic cylinder or an electric push rod.
[0029] A plurality of driving rollers 9 are provided between the conveying device 4 and the trimmer 3. The driving rollers 9 can be specifically arranged on the bracket 1. A third groove 91 adapted to the steel wire 7 is provided on the outer peripheral surface of the driving roller 9. The third grooves 91 between the plurality of driving rollers 9 form a driving channel, and the driving channel is aligned with the trimming channel 31. The driving roller 9 functions to drive and guide the steel wire 7 into the trimming channel 31. The conveying device 4 drives the steel wire 7 to sequentially pass through the driving channel and the trimming channel 31 into the curling channel. In this embodiment, the number of the driving rollers 9 is two. The trimmer 3 is inclined and aligned with the curling channel, and the two driving rollers 9 are also relatively inclined and aligned with the trimming channel 31, so that the conveying device 4 can drive the steel wire 7 to pass through the driving channel between the two driving rollers 9, then through the trimming channel 31, and finally enter the curling channel for curling.
[0030] With key reference to Figure 1 , the conveying device 4 is a rotatably arranged wire reel, and the wire reel is wound with the steel wire 7. Rotating the wire reel can release the steel wire 7. During curling, first pull out one end of the steel wire 7 from the wire reel, then sequentially pass through the driving channel and the trimming channel 31, and place it at the feeding end of the curling channel. Then start the curling disc 2 and the wire reel. While the curling disc 2 rotates, it drives the pressing roller 5 to rotate to press the steel wire 7 into an arc, and the wire reel rotates to continuously drive the steel wire 7 to pass through the curling channel to complete curling.
[0031] In addition, the conveying device 4 can also be other devices that can convey the steel wire 7 into the curling channel, which is not limited herein.
[0032] The above are only the preferred embodiments of the present utility model, and do not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
