Description

Technical Field

[0001] This application relates to the field of bar thread rolling, and in particular to a thread rolling machine that facilitates bar cleaning. Background Technology

[0002] A large thread rolling machine is a mechanical device used to roll threads onto the surface of bar stock, and it is widely used in construction, machinery manufacturing, and other fields. It typically consists of two symmetrical thread rolling rollers. The rotation of the rollers rolls the bar stock to form the desired thread structure. During the rolling process, cold rolling oil is sprayed onto the bar stock surface for cooling and lubrication to reduce temperature and friction.

[0003] During the operation of a thread rolling machine, the bar stock is fed between two thread rolling rollers by a feeding device. The thread rolling motor drives the rollers to rotate, rolling the bar stock. Simultaneously, cold rolling oil is sprayed onto the surface of the bar stock from the cold rolling oil pipe. The rolled bar stock is then output from the outlet. Due to the large amount of cold rolling oil used, a significant amount adheres to the surface of the bar stock during this process. In existing thread rolling machines, after the bar stock is rolled, the cold rolling oil adhering to its surface is removed from the equipment along with the bar stock, resulting in a large amount of residual cold rolling oil on the bar stock. This not only easily causes cold rolling oil dripping during subsequent transportation and production, polluting the working environment, but also leads to waste of cold rolling oil and increases production costs. Summary of the Invention

[0004] The purpose of this application is to address the problem mentioned in the background art that the cold rolling oil adhering to the surface of the bar is removed from the equipment along with the bar, resulting in a large amount of cold rolling oil remaining on the bar. This not only easily causes cold rolling oil to drip during subsequent transportation and production, polluting the working environment, but also leads to waste of cold rolling oil and increases production costs. This application provides a thread rolling machine that facilitates bar cleaning.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution: A convenient bar milling machine includes a main body with two symmetrically connected thread rolling rollers rotatably connected to it. A cold rolling oil tank is provided on the main body, and cold rolling oil pipes are installed at one end of each of the two thread rolling rollers. A discharge port is located at the end of the main body away from the thread rolling rollers. A support base one is fixed to the end of the main body near the discharge port, and the support base one is located within the cold rolling oil tank. A support base two is provided between the support base one and the discharge port of the main body, and is fixedly connected to the main body and located within the cold rolling oil tank. A cold rolling oil cleaning solution is provided between the support base one and the support base two. The cleaning mechanism includes an auxiliary cleaning mechanism on the support base 2. One end of the thread rolling roller is fixed with a thread rolling coupling rod 1, which is connected to a thread rolling coupling rod 2. The end of the thread rolling coupling rod 2 away from the thread rolling coupling rod 1 is connected to a thread rolling coupling rod 3. The end of the thread rolling coupling rod 3 away from the thread rolling coupling rod 2 is rotatably connected to the thread rolling machine body. Two symmetrical thread rolling motors are fixed on the thread rolling machine body. The output end of the thread rolling motor passes through the thread rolling machine body and is fixedly connected to the corresponding thread rolling coupling rod 3. Two symmetrical feed support wheels are rotatably connected to the end of the thread rolling machine body near the two thread rolling rollers.

[0006] By adopting the above technical solution, after the bar stock is pressed by two thread rolling rollers, it passes through the cold rolling oil cleaning mechanism as it moves towards the discharge port. The cold rolling oil cleaning mechanism removes the cold rolling oil from the bar stock. At the same time, the cold rolling oil cleaning mechanism drives an auxiliary cleaning mechanism to further clean the bar stock. This reduces the possibility of a large amount of cold rolling oil used for cooling remaining on the bar stock during pressing, and reduces the possibility of cold rolling oil dripping to other places during subsequent transport and production. It also allows the cold rolling oil to drip back into the cold rolling oil pool, reducing the waste of cold rolling oil.

[0007] Furthermore, the cold rolling oil cleaning mechanism includes a support frame mounted on the main body of the thread rolling machine. The support frame is U-shaped, and its two ends are fixedly connected to the main body of the thread rolling machine. Two symmetrical connecting frames are mounted on the support frame, and cleaning rollers, which are flexible rubber rollers, are rotatably connected to the connecting frames. A spacing adjustment component is provided between the support frame and the two connecting frames, a drive component is provided between the support frame and the two cleaning rollers, and a scraping component is provided between the connecting frames and the cleaning rollers.

[0008] By adopting the above technical solution, when the two cleaning rollers are pressed onto the bar, the cleaning rollers themselves deform under the pressure, allowing them to enter the grooves where the bar is pressed. During the contact between the cleaning rollers and the bar, the cold rolling oil on the bar adheres to the cleaning rollers, which are then scraped off by the scraping component. This reduces the possibility of a large amount of cold rolling oil used for cooling remaining on the bar during pressing, and also reduces the possibility of cold rolling oil dripping onto other places during subsequent bar transportation and production. At the same time, it allows the cold rolling oil to drip back into the cold rolling oil pool, reducing the waste of cold rolling oil.

[0009] Furthermore, the spacing adjustment assembly includes two spacing adjustment blocks symmetrically arranged on the support frame. The support frame has a spacing adjustment groove, and the two spacing adjustment blocks are located in the spacing adjustment groove and are slidably connected to the support frame. An adjusting bidirectional threaded rod is rotatably connected to the support frame. The adjusting bidirectional threaded rod is located in the spacing adjustment groove, passes through the two spacing adjustment blocks, and is threadedly connected to the spacing adjustment blocks. One end of the adjusting bidirectional threaded rod passes through the support frame and is fixed with a turntable.

[0010] By adopting the above technical solution, the two spacing adjustment blocks drive the connecting frame, which in turn drives the cleaning roller to move. This allows for easy adjustment of the spacing between the two cleaning rollers, enabling different sized bars to deform and fill the thread-rolling grooves of the bars under the pressure of the two cleaning rollers when passing between them.

[0011] Furthermore, the drive assembly includes two drive support blocks symmetrically arranged between two connecting frames. The two drive support blocks are fixedly connected to the corresponding connecting frames. A bevel gear one is rotatably connected to the drive support block. A bevel gear two is meshed with the bevel gear one. The bevel gear two passes through the connecting frame and is fixedly connected to the cleaning roller. A synchronizing element is provided between the two drive support blocks and the support frame.

[0012] By adopting the above technical solution, the synchronizing component drives the bevel gear one on the drive support block of the two connecting frames to rotate. The bevel gear one drives the bevel gear two to rotate, and the bevel gear two drives the cleaning roller to rotate, thereby enabling the cleaning roller to fully contact the bar and facilitating the contact between the cold rolling oil on the bar and the cleaning roller.

[0013] Furthermore, the synchronizing element includes a synchronizing drive frame fixed on a support frame. A drive gear 1 is rotatably connected to the synchronizing drive frame. Two symmetrical drive gears 2 are meshed on the drive gear 1. The two drive gears 2 are rotatably connected to the synchronizing drive frame. A drive motor is fixed on the synchronizing drive frame. The output end of the drive motor passes through the synchronizing drive frame and is fixedly connected to the drive gear 1. One end of the drive gear 2 passes through the synchronizing drive frame and is fixed to the synchronizing coupling rod 1. The end of the synchronizing coupling rod 1 away from the drive gear 2 is drivenly connected to the synchronizing coupling rod 2. The end of the synchronizing coupling rod 2 away from the synchronizing coupling rod 1 is drivenly connected to the synchronizing coupling rod 3. The synchronizing coupling rod 3 is rotatably connected to the drive support block. The synchronizing coupling rod 3 passes through the drive support block and is fixedly connected to the bevel gear 1. The synchronizing coupling rod 2 is a telescopic rod.

[0014] By adopting the above technical solution, the first drive gear drives two second drive gears, and the two second drive gears rotate simultaneously, causing the first bevel gear to rotate, thereby enabling the two cleaning rollers to rotate simultaneously and improving cleaning efficiency.

[0015] Furthermore, the scraping assembly includes two connecting rods symmetrically fixed on the connecting frame, and a scraping plate is fixed between the two connecting rods, the scraping plate abutting against the cleaning roller.

[0016] By adopting the above technical solution, the scraper between the two connecting rods abuts against the cleaning roller. When the cleaning roller rotates, the scraper scrapes off the cold rolling oil attached to the cleaning roller, thereby removing the cold rolling oil on the cleaning roller in time, which facilitates the subsequent attachment of cold rolling oil on the bar to the cleaning roller.

[0017] Furthermore, the auxiliary cleaning mechanism includes two auxiliary support rods symmetrically arranged on the support base 2. One end of each of the two auxiliary support rods is rotatably connected to an auxiliary support block. A following block is fixed on the auxiliary support block. The main body of the rolling mill has a following groove corresponding to the following block. The following block is located in the following groove and is slidably connected to the main body of the rolling mill. An auxiliary support rod 2 is arranged between the two auxiliary support rods 1. A cleaning cloth is driven between the two auxiliary support rods 1 and the auxiliary support rod 2. A tension adjustment component is arranged between the auxiliary support rod 2 and the main body of the rolling mill. A drive gear 3 is fixed to the end of the auxiliary support rod 1 away from the auxiliary support block. The end of the auxiliary support rod 1 away from the auxiliary support block is rotatably connected to the support frame. A drive gear 4 is fixed on the bevel gear 2. The drive gear 3 meshes with the drive gear 4.

[0018] By adopting the above technical solution, when the bar moves on the support seat 2, the cleaning cloth comes into contact with the bar and moves, thereby further reducing the amount of cold rolling oil adhering to the bar and reducing the trouble of cleaning the bar later.

[0019] Furthermore, the tension adjustment assembly includes a tension adjustment block disposed at one end of the auxiliary support rod two. The thread rolling machine body has a tension adjustment groove, the tension adjustment block is located in the tension adjustment groove and is slidably connected to the thread rolling machine body, an adjustment threaded rod is rotatably connected to the thread rolling machine body, the adjustment threaded rod is located in the tension adjustment groove and is threadedly connected to the tension adjustment block, and a connecting rotating block is fixed on the tension adjustment block, the connecting rotating block being rotatably connected to one end of the auxiliary support rod two.

[0020] By adopting the above technical solution, the tension adjustment block drives the auxiliary support rod two to move, thereby changing the support position of the auxiliary support rod two on the cleaning cloth. This allows for convenient adjustment of the cleaning cloth according to rods of different diameters, and also allows the cleaning cloth to adjust accordingly when the position of the auxiliary support rod one on the cleaning cloth changes.

[0021] In summary, this application includes at least one of the following beneficial effects; 1. In this application, after the bar stock is rolled, it moves on the support base under the push of subsequent bars. Then, the bar stock is squeezed between two cleaning rollers. The drive assembly drives the cleaning rollers on the two connecting frames to rotate, causing the two cleaning rollers to roll the bar stock. When the two cleaning rollers press against the bar stock, the cleaning rollers themselves are deformed by the pressure, allowing the cleaning rollers to enter the groove where the bar stock is rolled. During the contact between the cleaning rollers and the bar stock, the cold rolling oil on the bar stock adheres to the cleaning rollers. At the same time, the bar stock continues to move forward under the push of subsequent bars. While the cleaning rollers are rotating, the scraping assembly scrapes the rotating cleaning rollers, allowing the cold rolling oil to drip down the scraping assembly into the cold rolling oil pool. This achieves the goal of reducing the possibility of a large amount of cold rolling oil used for cooling remaining on the bar stock during rolling, reducing the possibility of cold rolling oil dripping to other places during the transportation and production of subsequent bars, and allowing the cold rolling oil to drip back into the cold rolling oil pool, thus reducing the waste of cold rolling oil.

[0022] 2. In this application, when the size of the bar stock being rolled by the thread rolling machine changes, the turntable is rotated, causing the adjusting bidirectional threaded rod to rotate. When the adjusting bidirectional threaded rod rotates, it drives two spacing adjustment blocks to move simultaneously. The two spacing adjustment blocks drive two symmetrical connecting frames, and the connecting frames drive the cleaning rollers to move. This allows the spacing between the two cleaning rollers to adapt to different bar stock sizes, achieving the purpose of conveniently adjusting the spacing between the two cleaning rollers. This allows bars of different sizes to deform and fill the thread rolling grooves of the bar stock under the compression between the two cleaning rollers when passing between them.

[0023] 3. In this application, when the bar passes over the support seat 2, it passes between the two auxiliary support rods 1 and under the cleaning cloth. The height of the two auxiliary support rods 1 is lower than that of the support seat 2. The tension adjustment mechanism drives the auxiliary support rods 2, which in turn drives the cleaning cloth, making the cleaning cloth taut. Under the limit of the auxiliary support rods 1, the cleaning cloth comes into contact with the bar. While the bevel gear 2 rotates, the bevel gear 2 drives the drive gear 4, the drive gear 4 drives the drive gear 3, and the drive gear 3 drives the auxiliary support rods 1, which in turn drives the cleaning cloth to rotate. The cleaning cloth further wipes the cold rolling oil on the bar. When adjusting the position of the cleaning roller, the connecting frame directly drives the auxiliary support rods 1, which in turn drives the auxiliary support block. The auxiliary support block moves under the support of the follower block, keeping the auxiliary support rods 1 and the cleaning roller aligned. This achieves the goal of further reducing the amount of cold rolling oil adhering to the bar and reducing the trouble of subsequent bar cleaning. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0027] This application discloses a wire rolling machine that facilitates the cleaning of bar stock.

[0028] Reference Figure 1 , Figure 2 and Figure 3A convenient bar milling machine includes a main body 1, on which two symmetrical thread rolling rollers 2 are rotatably connected. A cold rolling oil tank 3 is provided on the main body 1. Cold rolling oil pipes 4 are installed at one end of each of the two thread rolling rollers 2. A discharge port 9 is provided at the end of the main body 1 away from the thread rolling rollers 2. A support base 5 is fixed at the end of the main body 1 near the discharge port 9, and the support base 5 is located within the cold rolling oil tank 3. A second support base 6 is provided between the first support base 5 and the discharge port 9 of the main body 1, and is fixedly connected to the main body 1 and located within the cold rolling oil tank 3. A cold rolling oil cleaning mechanism 7 is provided between the first support base 5 and the second support base 6. An auxiliary cleaning mechanism 8 is provided on the support base 2 6. One end of the thread rolling roller 2 is fixed with a thread rolling coupling rod 12. A thread rolling coupling rod 2 13 is driven to the thread rolling coupling rod 12. The end of the thread rolling coupling rod 2 13 away from the thread rolling coupling rod 12 is driven to the thread rolling coupling rod 3 14. The end of the thread rolling coupling rod 3 14 away from the thread rolling coupling rod 2 13 is rotatably connected to the thread rolling machine body 1. Two symmetrical thread rolling motors 10 are fixed on the thread rolling machine body 1. The output end of the thread rolling motor 10 passes through the thread rolling machine body 1 and is fixedly connected to the corresponding thread rolling coupling rod 3 14. Two symmetrical feed support wheels 11 are rotatably connected to the end of the thread rolling machine body 1 near the two thread rolling rollers 2.

[0029] When using the thread rolling machine, the feed support wheel 11 on the main body 1 of the thread rolling machine is aligned with the external bar feeding device, allowing the bar to move between the two thread rolling rollers 2. The thread rolling motor 10 drives the thread rolling coupling rod 3 14, which in turn drives the thread rolling coupling rod 2 13, which in turn drives the thread rolling coupling rod 1 12. The thread rolling coupling rod 1 12 then drives the thread rolling rollers 2 to rotate, pressing the bar. Simultaneously, the oil in the cold rolling oil tank 3 is pumped from the cold rolling oil tank 3 to the cold rolling oil tank using a transfer pump. The cold rolling oil in the oil pipe 4 is poured onto the bar being rolled. Simultaneously, driven by the two thread rolling rollers 2, the bar moves towards the discharge port 9. During this movement, it passes through support base 1 5 and support base 2 6. As the bar passes these supports, the cold rolling oil on it drips into the cold rolling oil pool 3 due to gravity. While the bar moves along support bases 1 5 and 2 6, the cold rolling oil cleaning mechanism 7 abuts against both sides of the bar. The cold rolling oil cleaning mechanism 7 cleans the bar... The cold rolling oil on the bar is scraped off to reduce its residue. During the cleaning process by the cold rolling oil cleaning mechanism 7, the mechanism drives the auxiliary cleaning mechanism 8, which rubs across the rolling bar to further reduce residue. Finally, the rolled bar exits from the discharge port 9 of the main body 1 of the thread rolling machine, completing the thread rolling process. This is achieved by having the bar rolled by two thread rolling rollers 2 before moving towards the discharge port 9. During the process, the bar passes through the cold rolling oil cleaning mechanism 7, which removes the cold rolling oil from the bar. At the same time, the cold rolling oil cleaning mechanism 7 drives the auxiliary cleaning mechanism 8 to further clean the bar. This reduces the possibility of a large amount of cold rolling oil used for cooling remaining on the bar during the rolling process, and reduces the possibility of cold rolling oil dripping to other places during subsequent bar transportation and production. It also allows the cold rolling oil to drip back into the cold rolling oil pool 3, reducing the waste of cold rolling oil.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The cold rolling oil cleaning mechanism 7 includes a support frame 71 mounted on the main body 1 of the thread rolling machine. The support frame 71 is U-shaped, and both ends of the support frame 71 are fixedly connected to the main body 1 of the thread rolling machine. Two symmetrical connecting frames 72 are mounted on the support frame 71, and cleaning rollers 73 are rotatably connected to the connecting frames 72. The cleaning rollers 73 are flexible rubber rollers. A spacing adjustment component 74 is provided between the support frame 71 and the two connecting frames 72. A drive component 75 is provided between the support frame 71 and the two cleaning rollers 73. A scraping component 76 is provided between the connecting frames 72 and the cleaning rollers 73.

[0031] After the bar stock is rolled, it moves on support seat 5 under the push of subsequent bars. The bar stock is then squeezed between two cleaning rollers 73, which are made of fluororubber. Drive assembly 75 rotates the cleaning rollers 73 on the two connecting frames 72, causing the two cleaning rollers 73 to roll the bar stock. When the two cleaning rollers 73 press against the bar stock, they deform under pressure, allowing them to enter the rolling groove. During the contact between the cleaning rollers 73 and the bar stock, the cold rolling oil on the bar stock adheres to the cleaning rollers 73. Simultaneously, the bar stock continues to move forward under the push of subsequent bars. While the bar stock is being cleaned by the two cleaning rollers 73, it moves from support seat 5 to support seat 6, reducing the chance of the cold rolling oil on support seat 5 coming into contact with the bar stock again after cleaning. When the bar stock is long, one end may be directly between the two cleaning rollers 73 during rolling. Between 3, two cleaning rollers 73 rotate directly on the bar, maintaining the original rolling rotation. The cleaning rollers 73 directly wipe away the cold rolling oil on the bar while it is rolling. At the same time as the cleaning rollers 73 rotate, the scraping component 76 scrapes the rotating cleaning rollers 73, allowing the cold rolling oil to drip down into the cold rolling oil pool 3. When the bar moves from support 1 5 to support 2 6, it passes between the two rotating cleaning rollers 73. The cold rolling oil on the bar adheres to the rotating cleaning rollers 73, and then the scraping component 76 scrapes the cold rolling oil off the cleaning rollers 73 and drips it into the cold rolling oil pool 3. This reduces the possibility of a large amount of cold rolling oil used for cooling remaining on the bar during rolling, and reduces the possibility of cold rolling oil dripping to other places during subsequent bar transportation and production. At the same time, it allows the cold rolling oil to drip back into the cold rolling oil pool 3, reducing the waste of cold rolling oil.

[0032] Reference Figure 2 and Figure 3 The spacing adjustment assembly 74 includes two spacing adjustment blocks 741 symmetrically arranged on the support frame 71. The support frame 71 has a spacing adjustment groove 743. The two spacing adjustment blocks 741 are located in the spacing adjustment groove 743 and are slidably connected to the support frame 71. An adjusting bidirectional threaded rod 742 is rotatably connected to the support frame 71. The adjusting bidirectional threaded rod 742 is located in the spacing adjustment groove 743. The adjusting bidirectional threaded rod 742 passes through the two spacing adjustment blocks 741 and is threadedly connected to the spacing adjustment blocks 741. One end of the adjusting bidirectional threaded rod 742 passes through the support frame 71 and is fixed with a turntable.

[0033] When the size of the bar stock being rolled by the thread rolling machine changes, the turntable is rotated, causing the adjusting bidirectional threaded rod 742 to rotate. The rotation of the adjusting bidirectional threaded rod 742 drives two spacing adjusting blocks 741 to move simultaneously. The two spacing adjusting blocks 741 drive two symmetrical connecting frames 72, which in turn drive the cleaning rollers 73 to move. This allows the spacing between the two cleaning rollers 73 to adapt to different bar stock sizes. By having the adjusting bidirectional threaded rod 742 drive the two spacing adjusting blocks 741 to move simultaneously, and the two spacing adjusting blocks 741 drive the connecting frames 72, which in turn drive the cleaning rollers 73, the spacing between the two cleaning rollers 73 can be easily adjusted. This allows bars of different sizes to pass between the two cleaning rollers 73, where the pressure between the two cleaning rollers 73 causes the cleaning rollers 73 to deform and fill the thread rolling grooves of the bar stock.

[0034] Reference Figure 3 , Figure 4 and Figure 5 The drive assembly 75 includes two drive support blocks 751 symmetrically arranged between two connecting frames 72. The two drive support blocks 751 are fixedly connected to the corresponding connecting frames 72. A bevel gear 752 is rotatably connected to the drive support block 751. A bevel gear 753 is meshed on the bevel gear 752. The bevel gear 753 passes through the connecting frame 72 and is fixedly connected to the cleaning roller 73. A synchronizing element 754 is provided between the two drive support blocks 751 and the support frame 71.

[0035] The rolled bar moves between two cleaning rollers 73 under the push of subsequent bars. During the movement of the bar, the synchronizing component 754 drives the bevel gear 752 on the support block 751 of the two connecting frames 72 to rotate. The bevel gear 752 drives the bevel gear 753 to rotate, and the bevel gear 753 drives the cleaning rollers 73 to rotate. When the two cleaning rollers 73 rotate, they drive the bar to rotate, and at the same time, the cold rolling oil on the bar adheres to the cleaning rollers 73. By allowing the bar to pass through the two cleaning rollers 73, the two cleaning rollers 73 rotate simultaneously, and the cleaning rollers 73 drive the bar to rotate, so that the cleaning rollers 73 can make full contact with the bar, and facilitate the contact of the cold rolling oil on the bar with the cleaning rollers 73.

[0036] Reference Figure 4 and Figure 5The synchronizing element 754 includes a synchronizing drive frame 7541 fixed on a support frame 71. A drive gear 7542 is rotatably connected to the synchronizing drive frame 7541. Two symmetrical drive gears 7543 are meshed on the drive gear 7542. The two drive gears 7543 are rotatably connected to the synchronizing drive frame 7541. A drive motor is fixed on the synchronizing drive frame 7541. The output end of the drive motor passes through the synchronizing drive frame 7541 and is fixedly connected to the drive gear 7542. One end of the drive gear 7543 passes through the synchronizing drive frame 7541. The drive frame 7541 is fixed to the first synchronous coupling rod 7544. The end of the first synchronous coupling rod 7544 away from the second drive gear 7543 is connected to the second synchronous coupling rod 7545. The end of the second synchronous coupling rod 7545 away from the first synchronous coupling rod 7544 is connected to the third synchronous coupling rod 7546. The third synchronous coupling rod 7546 is rotatably connected to the drive support block 751. The third synchronous coupling rod 7546 passes through the drive support block 751 and is fixedly connected to the first bevel gear 752. The second synchronous coupling rod 7545 is a telescopic rod.

[0037] When it is necessary for both cleaning rollers 73 to rotate simultaneously, the drive motor drives drive gear 1 7542 to rotate. Drive gear 1 7542 simultaneously drives two drive gears 2 7543 to rotate. The two drive gears 2 7543 drive synchronous coupling rod 1 7544, synchronous coupling rod 1 7544 drives synchronous coupling rod 2 7545, synchronous coupling rod 2 7545 drives synchronous coupling rod 3 7546, and synchronous coupling rod 3 7546 drives the corresponding bevel gear 1 752 to rotate. At the same time, synchronous coupling rod 2 7545 is a telescopic rod. When adjusting the distance between the two cleaning rollers 73, synchronous coupling rod 2 7545 can adaptively adjust the distance, reducing the possibility of obstructing the movement of the cleaning rollers. By using drive gear 1 7542 to drive two drive gears 2 7543, and the two drive gears 2 7543 rotating simultaneously, bevel gear 1 752 can be rotated, thereby enabling both cleaning rollers 73 to rotate simultaneously, improving cleaning efficiency.

[0038] Reference Figure 2 and Figure 3 The scraping assembly 76 includes two symmetrically fixed connecting rods 761 on the connecting frame 72. A scraping plate 762 is fixed between the two connecting rods 761, and the scraping plate 762 abuts against the cleaning roller 73. The cleaning roller 73 rotates on the connecting frame 72. After the cleaning roller 73 comes into contact with the bar stock, cold rolling oil adheres to the cleaning roller 73. The scraping plate 762 between the two connecting rods 761 abuts against the cleaning roller 73. When the cleaning roller 73 rotates, the scraping plate 762 scrapes off the cold rolling oil adhering to the cleaning roller 73, allowing the cold rolling oil to drip down the scraper into the cold rolling oil pool 3. By having the scraping plate 762 abut against the cleaning roller when the cleaning roller rotates, the cold rolling oil on the cleaning roller can be scraped off in time, making it easier for the cold rolling oil on the bar stock to adhere to the cleaning roller in the future.

[0039] Reference Figure 2 , Figure 6 and Figure 7 The auxiliary cleaning mechanism 8 includes two auxiliary support rods 81 symmetrically arranged on the support base 6. One end of each auxiliary support rod 81 is rotatably connected to an auxiliary support block 82. A follower block 88 is fixed on the auxiliary support block 82. The main body 1 of the rolling machine has a follower groove corresponding to the follower block 88. The follower block 88 is located in the follower groove and is slidably connected to the main body 1 of the rolling machine. An auxiliary support rod 83 is arranged between the two auxiliary support rods 81. A cleaning cloth 87 is connected between the two auxiliary support rods 81 and the auxiliary support rod 83. A tension adjustment component 86 is arranged between the auxiliary support rod 83 and the main body 1 of the rolling machine. A drive gear 84 is fixed at the end of the auxiliary support rod 81 away from the auxiliary support block 82. The end of the auxiliary support rod 81 away from the auxiliary support block 82 is rotatably connected to the support frame 71. A drive gear 85 is fixed on the bevel gear 753. The drive gear 84 meshes with the drive gear 85.

[0040] As the rod passes over support base 26, it passes between the two auxiliary support rods 181 and under the cleaning cloth 87. The height of the two auxiliary support rods 181 is lower than that of support base 26. The tension adjustment mechanism drives auxiliary support rod 283, which in turn drives the cleaning cloth 87, tautning it. Under the limit of auxiliary support rod 181, the cleaning cloth 87 comes into contact with the rod. Simultaneously, bevel gear 2753 rotates, driving drive gear 485, which in turn drives drive gear 384, which in turn drives the auxiliary support rods. Auxiliary support rod 81 drives cleaning cloth 87 to rotate, and cleaning cloth 87 further wipes the cold rolling oil on the bar. When adjusting the position of cleaning roller 73, connecting frame 72 directly drives auxiliary support rod 81, and auxiliary support rod 81 drives auxiliary support block 82. Auxiliary support block 82 moves under the support of follower block 88, so that auxiliary support rod 81 and cleaning roller 73 are aligned. When the bar moves on support seat 6, the cleaning cloth 87 abuts against the bar and moves, thereby further reducing the cold rolling oil adhering to the bar and reducing the trouble of cleaning the bar later.

[0041] Reference Figure 2 and Figure 6The tension adjustment assembly 86 includes a tension adjustment block 861 disposed at one end of the auxiliary support rod 83. The main body 1 of the thread rolling machine is provided with a tension adjustment groove. The tension adjustment block 861 is located in the tension adjustment groove and is slidably connected to the main body 1 of the thread rolling machine. An adjustment threaded rod 862 is rotatably connected to the main body 1 of the thread rolling machine. The adjustment threaded rod 862 is located in the tension adjustment groove and is threadedly connected to the tension adjustment block 861. A connecting rotating block 863 is fixed on the tension adjustment block 861. The connecting rotating block 863 is rotatably connected to one end of the auxiliary support rod 83.

[0042] When changing the distance between the two cleaning rollers 73, the connecting frame 72 moves the auxiliary support rod 81. One end of the adjusting threaded rod 862 passes through the main body 1 of the thread rolling machine. Rotating the adjusting threaded rod 862 first moves the tension adjusting block 861, which in turn moves the connecting rotating block 863. The connecting rotating block 863 then moves the auxiliary support rod 83, which in turn loosens the cleaning cloth 87. After the distance between the two auxiliary support rods 81 is adjusted to follow the cleaning rollers 73, the adjusting threaded rod 862 is rotated. The adjusting threaded rod 862 drives the tension adjusting block 861, which in turn drives the connecting rotating block 863. The connecting rotating block 863 then drives the auxiliary support rod 83, which in turn supports the cleaning cloth 87. By moving the auxiliary support rod 83 through the tension adjusting block 861, the support position of the auxiliary support rod 83 on the cleaning cloth 87 can be changed. This allows for easy adjustment of the cleaning cloth 87 according to rods of different diameters. Additionally, the cleaning cloth 87 can be adjusted accordingly when the position of the auxiliary support rod 81 on the cleaning cloth 87 changes.

[0043] Working principle: When using the thread rolling machine, the feed support wheel 11 on the main body 1 of the thread rolling machine is aligned with the external bar feeding device, allowing the bar to move between the two thread rolling rollers 2. The thread rolling motor 10 drives the thread rolling coupling rod 3 14, which in turn drives the thread rolling coupling rod 2 13. The thread rolling coupling rod 2 13 drives the thread rolling coupling rod 1 12, which in turn drives the thread rolling roller 2 to rotate. The thread rolling roller 2 presses the bar. At the same time, the oil in the cold rolling oil tank 3 is pumped from the cold rolling oil tank 3 to the cold rolling oil pipe 4 using a transfer pump, allowing the cold rolling oil in the cold rolling oil pipe 4 to be poured onto the bar being pressed. Simultaneously, the two thread rolling rollers 2... Under the influence of the movement, the bar moves towards the discharge port 9. During this movement, it passes through support base 1 5 and support base 2 6. As the bar passes through support base 1 5 and support base 2 6, the cold rolling oil on the bar drips into the cold rolling oil pool 3 due to gravity. Simultaneously, driven by subsequent bars, the bar moves on support base 1 5 and then squeezes between two cleaning rollers 73. The drive motor drives drive gear 1 7542 to rotate, which in turn drives two drive gears 2 7543 to rotate. The two drive gears 2 7543 drive synchronous coupling rod 1 7544. 44 drives synchronous coupling two 7545, synchronous coupling two 7545 drives synchronous coupling three 7546, synchronous coupling three 7546 drives the corresponding bevel gear one 752 to rotate, bevel gear one 752 drives bevel gear two 753, bevel gear two 753 drives cleaning roller 73 to rotate, causing the two cleaning rollers 73 to drive the bar to roll. When the two cleaning rollers 73 are pressed on the bar, the cleaning roller 73 itself is deformed by the compression, allowing the cleaning roller 73 to enter the groove of the bar pressing. During the contact process between the cleaning roller 73 and the bar, the cold rolling oil on the bar adheres to the cleaning roller 73. At the same time, the bar continues to be pushed by the subsequent bar. Continuing forward, the scraper 762 between the two connecting rods 761 abuts against the cleaning roller 73. As the cleaning roller 73 rotates, the scraper 762 scrapes off the cold rolling oil adhering to the cleaning roller 73, allowing the cold rolling oil to drip down the scraper into the cold rolling oil pool 3. At the same time, the bevel gear 753 rotates, driving the drive gear 85, which in turn drives the drive gear 84. The drive gear 84 then drives the auxiliary support rod 81, causing the auxiliary support rod 81 to rotate the cleaning cloth 87. The cleaning cloth 87 further wipes the cold rolling oil off the bar, and then the bar that has completed the rolling and pressing is discharged from the discharge port 9.
