Description

Technical Field

[0001] This utility model relates to the field of automatic rolling straightening and positioning technology, specifically a rolling device for processing bearing steel bars that facilitates positioning. Background Technology

[0002] The processing flow of bearing steel bars usually begins with heating the steel ingot. After the steel ingot is heated to a suitable plastic deformation temperature in a heating furnace, it is gradually compressed into bars of the required specifications through primary rolling and multiple repeated rolling passes. During the rolling process, the steel ingot is repeatedly squeezed by the upper and lower rolls in the rolling mill, gradually reducing the cross-sectional size and extending the length. After finishing rolling and cooling, bearing steel bars with accurate dimensions and high surface quality are obtained.

[0003] According to a public notice (No. CN111330983B) regarding a straightening and positioning device in the automatic rolling process of steel plates, the aforementioned application includes a base, with an anti-pressure, anti-slip, and shock-absorbing pad at the bottom of the base. A material conveying support column and a rolling support column are fixedly mounted on the base. A material conveying support beam is mounted on the material conveying support column, and several conveying rollers are mounted on the material conveying support beam. A rolling roller is symmetrically arranged on the rolling support column, and several adjusting bases are mounted on the support beam. A steel plate straightening device is mounted on the adjusting base.

[0004] However, in actual use, the above-mentioned straightening and positioning device can only correct slightly offset steel because the distance between the guide wheels is fixed. For steel with large offset, the telescopic rod will block the movement of the steel and prevent it from smoothly entering the straightening device or between the rolling rolls, causing the entire production line to stop or requiring manual intervention, thus extending the production cycle. In view of this, we propose a rolling device for processing bearing steel bars that is easy to position. Utility Model Content

[0005] The purpose of this invention is to provide a rolling device for processing bearing steel bars that is easy to position, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rolling device for processing bearing steel bars that facilitates positioning, comprising a frame, rolling rollers rotatably connected to the side walls of the frame, conveying rollers rotatably connected to the side walls of the frame, and a positioning assembly provided on the top end face of the frame, the positioning assembly comprising:

[0007] A rotating shaft is fixedly connected to the top end face of the frame. A plug is inserted into the top of the rotating shaft, and a protruding strip is fixedly connected to the bottom end face of the plug.

[0008] The mounting bracket is slidably connected to the side wall of the rotating shaft. The top end face of the mounting bracket has a groove, the end face of the mounting bracket is rotatably connected to a guide wheel, and the side wall of the mounting bracket has a sliding groove.

[0009] The elastic telescopic rod is fixedly connected to a bracket on the top end face of the frame, and the elastic telescopic rod is fixedly connected to the side wall of the bracket.

[0010] Preferably, the number of positioning components is set to several groups, and the several groups of positioning components are symmetrically arranged at equal intervals on the top end face of the frame, and the positioning components are positioned above the conveying roller.

[0011] Preferably, the protrusion is inserted into the groove, and the number of grooves is set in several groups, with the several groups of grooves evenly spaced on the top end face of the mounting frame.

[0012] Preferably, a slider is fixedly connected to the end of the elastic telescopic rod away from the bracket, and the slider is slidably connected to the groove.

[0013] Preferably, the inner bottom surface of the rotating shaft has a slot one, and the top of the insert block has a slot two. The slot one is inserted into the pin, and the slot two is inserted into the pin, so that the insert block and the mounting bracket cannot rotate.

[0014] Preferably, the elastic telescopic rod is arc-shaped, with its center coinciding with the axis of the rotating shaft. The elastic telescopic rod is located on the side of the mounting frame closer to the rolling roll, and the mounting frame is reset by the elastic deformation of the elastic telescopic rod.

[0015] Compared with the prior art, this utility model provides a rolling device for processing bearing steel bars that is easy to position, and has the following beneficial effects:

[0016] 1. This easy-to-position rolling device for processing bearing steel bars, through the installation frame and elastic telescopic rod, allows the steel to push the installation frame, causing the installation frame and insert blocks to rotate around the shaft. At this time, the elastic telescopic rod undergoes elastic deformation, pushing the steel back to the center of the conveyor roller without manual intervention. The misaligned steel is pushed back to the center of the conveyor roller, ensuring that the subsequent rolling rollers can work normally, improving the straightening efficiency. Adjusting the insertion of different grooves and convex strips can adjust the spacing between the guide wheels, adapting to steel of different widths, meeting the needs of multi-specification production, and improving the versatility of the equipment.

[0017] 2. This easy-to-position rolling device for processing bearing steel bars uses a set pin that is inserted into slot one and slot two. At this time, the mounting frame will not rotate. During transportation, the equipment may be subjected to external vibration or impact. By locking the pin, the mounting frame and the insert block are kept in a fixed position to prevent positional changes due to vibration or collision, thereby ensuring the stability of the equipment.

[0024] Example 1

[0025] like Figures 1-3 As shown, this utility model provides a technical solution: a rolling device for processing bearing steel bars that is easy to position, including a frame 1, a rolling roller 2 rotatably connected to the side wall of the frame 1, a conveying roller 3 rotatably connected to the side wall of the frame 1, and a positioning component 4 provided on the top end face of the frame 1. The positioning component 4 includes a rotating shaft 401, an insert block 402, a protrusion 403, a mounting bracket 404, a groove 405, a guide wheel 406, a slide 407, a bracket 408, an elastic telescopic rod 409, and a slider 410.

[0026] In one embodiment of this utility model, the number of positioning components 4 is set to several groups, and the several groups of positioning components 4 are symmetrically arranged at equal intervals on the top end face of the frame 1, and the positioning components 4 are positioned above the conveying roller 3.

[0027] The rotating shaft 401 is fixedly connected to the top end face of the frame 1. A plug 402 is inserted into the top of the rotating shaft 401, and a protrusion 403 is fixedly connected to the bottom end face of the plug 402.

[0028] Mounting bracket 404 is slidably connected to the side wall of rotating shaft 401. A groove 405 is provided on the top end face of mounting bracket 404. A protrusion 403 is inserted into the groove 405. A guide wheel 406 is rotatably connected to the end face of mounting bracket 404. A sliding groove 407 is provided on the side wall of mounting bracket 404.

[0029] A bracket 408 is fixedly connected to the top end face of the frame 1. An elastic telescopic rod 409 is fixedly connected to the side wall of the bracket 408. The elastic telescopic rod 409 is arc-shaped, and the center of the elastic telescopic rod 409 coincides with the axis of the rotating shaft 401. The elastic telescopic rod 409 is located on the side of the mounting frame 404 close to the rolling roll 2. The elastic deformation of the elastic telescopic rod 409 pushes the mounting frame 404 to reset.

[0030] As the steel moves on the conveyor roller 3, if the steel deviates too much and cannot pass between the two sets of guide wheels 406, the steel will push the mounting frame 404, causing the mounting frame 404 and the insert block 402 to rotate around the rotating shaft 401. At this time, the elastic telescopic rod 409 undergoes elastic deformation and pushes the steel in the opposite direction to the middle of the conveyor roller 3. Without manual intervention, the deviated steel is pushed back to the middle of the conveyor roller 3, ensuring that the subsequent rolling roller 2 can work normally and improving the correction efficiency.

[0031] The number of grooves 405 is set in several groups, and the several groups of grooves 405 are equally spaced on the top end face of the mounting frame 404. By adjusting the insertion of different grooves 405 and protrusions 403, the spacing between guide wheels 406 can be adjusted, which can adapt to steel of different widths, meet the needs of multi-specification production, and improve the versatility of the equipment.

[0032] In addition, a slider 410 is fixedly connected to the end of the elastic telescopic rod 409 away from the bracket 408. The slider 410 is slidably connected to the slide groove 407. No matter how the mounting bracket 404 is adjusted, the elastic telescopic rod 409 always abuts against the mounting bracket 404. The elasticity of the elastic telescopic rod 409 pushes the mounting bracket 404 to reset. While adjusting the position of the guide wheel 406, the elastic telescopic rod 409 automatically adapts to the changes in the mounting bracket 404. There is no need to adjust the elastic telescopic rod 409 separately, which simplifies the operation steps and ensures that the equipment can operate normally under different settings.

[0033] In this utility model, when in use, the steel pushes the mounting frame 404, causing the mounting frame 404 and the insert block 402 to rotate around the rotating shaft 401. The elastic telescopic rod 409 pushes the steel to the middle of the conveying roller 3 in the opposite direction. By adjusting the insertion of different grooves 405 and protrusions 403, and adjusting the distance between guide wheels 406, it can adapt to steel of different widths and meet the needs of multi-specification production.

[0034] Example 2

[0035] like Figures 4-5 As shown, this invention improves upon Embodiment 1 to obtain a new technical solution: A slot 5 is provided on the inner bottom surface of the rotating shaft 401, and a slot 6 is provided on the top of the insert block 402. Slot 5 is engaged with a pin 7, and slot 6 is engaged with the pin 7, preventing the insert block 402 and the mounting bracket 404 from rotating. By adjusting the engagement of different grooves 405 and protrusions 403, the distance between the guide wheels 406 can be adjusted. When the pin 7 is engaged with slot 5 and slot 6, the mounting bracket 404 will not rotate. During transportation, the equipment may be subjected to external vibration or impact. By locking the pin 7, the mounting bracket 404 and the insert block 402 are kept in a fixed position, preventing positional changes due to vibration or collision, thus ensuring the stability of the equipment. Furthermore, under high load or complex operation conditions, locking the position of the mounting bracket 404 prevents unnecessary rotation, which helps ensure the correct alignment and positioning of the steel and ensures rolling accuracy.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
