[0011] The beneficial effects of the present invention are as follows: 1. When straightening the steel pipe used for scaffolding, due to the long length of the steel pipe, its end enters from the feed port, and the weight of the part that has not entered is large, which will cause the part of the steel pipe outside the straightener to deviate downward, making it difficult to position and stabilize the steel pipe. The present invention provides a feeding mechanism to support the tail end of the steel pipe to keep it stable, and performs preliminary straightening adjustment on the position where the tail end of the steel pipe is more bent, so as to avoid the steel pipe being bent too much when straightening inside the machine. Due to the continuous rotation of the steel pipe, it is easy to whip the surrounding staff, so as to avoid the need for a larger site during the straightening work to avoid injuries. By performing preliminary cleaning on the surface of the steel pipe, it is avoided that incomplete cleaning inside the cleaning mechanism causes debris to enter the inside of the machine and gradually accumulate, affecting the operation of the machine.
[0012] 2. When the bending degree of the steel pipe is too large, the steel pipe will be stuck outside the machine and cannot enter the machine, and the bending arc is large, which makes it easy for the steel pipe to whip the surrounding workers when rotating, requiring a larger work site. The present invention arranges a straightening component so that the part of the steel pipe that has not entered the machine is preliminarily straightened by the hole in the middle of the straightening ring, and the large pieces of debris on the surface of the steel pipe are preliminarily cleaned up to reduce the debris from entering the interior of the machine, and avoids the steel pipe from being swung outward due to the large bending angle when rotating. The large range is large, which is easy to cause danger. At the same time, the steel pipe with a large bending angle is prevented from being stuck at the entrance of the machine and affecting the straightening work.
[0013] 3. During the rotation of the bracket, due to the large gravity of the steel pipe and the long steel pipe, the end of the steel pipe in contact with the U-shaped block is easy to bend up during the rotation and lifting of the bracket, causing the steel pipe to fall off. The present invention provides a limit assembly and a pretreatment assembly to simply clean and polish the surface of the steel pipe, thereby reducing dust and debris on its surface, reducing debris on the surface of the steel pipe entering the cleaning mechanism, facilitating the maintenance of the cleanliness of the interior of the machine, and reducing the entry of debris. At the same time, the stability of the steel pipe is enhanced, so that the steel pipe and the machine are kept in a horizontal state before entering the cleaning mechanism, so that the steel pipe can complete autonomous loading, avoiding the need to quickly evacuate the steel pipe after manually inserting it into the machine, so as to avoid being pulled out by the bent steel pipe and causing injuries.
[0014] 4. After working for a period of time, the surfaces of the grinding wheel and the feeding roller are squeezed with the steel pipe, so that powdery debris such as cement ash is easy to clump and adhere to the surfaces of the grinding wheel and the feeding roller, resulting in the separation of the feeding roller and the grinding wheel from the steel pipe, resulting in the deterioration of the shaping effect of the feeding roller and the grinding effect of the grinding wheel. The present invention arranges a cleaning component to scrape the surfaces of the feeding roller and the grinding wheel. When scraping cannot be cleaned, the debris is crushed and cleaned with a scraper to ensure the use effect of the feeding roller and the grinding wheel. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Example 1, using Figure 1-Figure 6 A straightening machine for pipes according to one embodiment of the present invention is described as follows.
[0019] like Figure 1-Figure 6 As shown, a straightening machine for pipe fittings according to the present invention comprises a machine platform 1, a straightening mechanism 3 is fixedly connected to the top of the machine platform 1, and a control console 6 is fixedly connected to one end of the top of the machine platform 1 close to the straightening mechanism 3; The straightening machine for pipe fittings also includes: A cleaning mechanism 4, the bottom of which is fixedly connected to the top of the machine platform 1; The cleaning mechanism 4 includes a feeding box 401, the inner wall of which is rotatably connected to a feeding roller 403, the outer wall of which is fixedly connected to a dustproof box 404, and the inner wall of the dustproof box 404 is rotatably connected to a cleaning component 406 on a side close to the feeding roller 403; A feeding mechanism 5, the outer wall of which is fixedly connected to the outer wall of the machine 1 at one end close to the cleaning mechanism 4; The top end of the machine 1 away from the control console 6 is fixedly connected to the driving source 2 , the outer wall of the rotating plate 504 is rotatably connected to the inner wall of the bracket 502 , and the cleaning mechanism 4 is located between the driving source 2 and the control console 6 .
[0020] During operation, the machine 1 is turned on through the control console 6, and then the feeding mechanism 5 is turned on. The worker inserts one end of the long steel pipe into the feeding mechanism 5 so that it clamps the steel pipe. Then the feeding mechanism 5 inserts the steel pipe into the cleaning mechanism 4, and cleans the surface of the steel pipe inside the cleaning mechanism 4, so that cement and other debris attached to the steel pipe fall off and are discharged from the machine 1. The cleaned steel pipe enters the straightening mechanism 3 for correction. Driven by the straightening mechanism 3, the steel pipe rotates and enters the inside of the machine 1. During this process, the feeding mechanism 5 preliminarily straightens and pre-cleans the larger curved parts of the steel pipe, and finally the straightened steel pipe is taken out from the other side of the machine 1.
[0021] The feeding mechanism 5 includes a driving seat 501, the outer wall of the driving seat 501 is fixedly connected to the outer wall of the machine 1 at one end close to the cleaning mechanism 4, the inner wall of the driving seat 501 is rotatably connected to a bracket 502, the end of the bracket 502 away from the driving seat 501 is fixedly connected to a limiting component 503, a rotating plate 504 is symmetrically arranged at one end of the bracket 502 away from the limiting component 503, the opposite side of the rotating plate 504 is rotatably connected to a pre-treatment component 505, and the end of the rotating plate 504 away from the pre-treatment component 505 is fixedly connected to a straightening component 506.
[0022] At the beginning, the bracket 502 is placed flat on the ground, and the worker passes the steel pipe through the straightening component 506, then passes it into the pretreatment component 505, and finally clamps it on the limit component 503, and then turns on the driving seat 501, so that the driving seat 501 drives the bracket 502 to rotate. During the rotation of the bracket 502, the rotating plate 504 always keeps the pretreatment component 505 and the straightening component 506 in a horizontal state, so the steel pipe in the limit component 503 will rotate along the limit component 503, and finally when it is separated from the limit component 503, the steel pipe will be placed on the outside of the cleaning mechanism 4, and the straightening component 506 will push the steel pipe to the cleaning mechanism 4. Internal insertion allows the head of the steel pipe to enter the interior of the machine 1 to obtain initial power, allowing the steel pipe to rotate and enter the interior of the machine 1, supporting the tail end of the steel pipe so that the position with a larger bend at the tail end can be initially straightened and adjusted to avoid whipping the surrounding workers due to the continuous rotation of the steel pipe when straightening the steel pipe inside the machine 1, avoiding the need for a larger site during straightening work to avoid injuries, and performing a preliminary cleaning of the surface of the steel pipe to avoid incomplete cleaning inside the cleaning mechanism 4, which causes debris to enter the interior of the machine 1, resulting in accumulation of debris inside the machine 1 and affecting the operation of the machine 1.
[0023] The cleaning mechanism 4 also includes an auxiliary roller 402, the outer wall of the auxiliary roller 402 is rotatably connected to the inner wall of the loading box 401 away from the loading roller 403, the bottom of the dustproof box 404 is fixedly connected to the top of the machine 1, the inner wall of the dustproof box 404 is rotatably connected with a grinding wheel 405, and a discharge trough 407 is opened at one end of the inner wall of the machine 1 close to the dustproof box 404.
[0024] The feeding mechanism 5 places the steel pipe on the auxiliary roller 402, and then the straightening component 506 inserts the steel pipe into the bottom of the feeding roller 403, so that the steel pipe enters the dust box 404 driven by the feeding roller 403 and the auxiliary roller 402, and then enters the straightening mechanism 3, so that the steel pipe is squeezed and obtains the force to move toward the inside of the machine 1. When the steel pipe rotates and moves toward the inside of the machine 1, the grinding wheel 405 grinds the surface of the steel pipe, so that the cement or debris on the surface of the steel pipe is cleaned and falls into the discharge chute 407 and is discharged. The cleaning component cleans the debris adhered to the surface of the feeding roller 403 and the grinding wheel 405, keeps the surface of the feeding roller 403 and the grinding wheel 405 clean, and makes the steel pipe fully cleaned to prevent debris from being brought into the inside of the machine 1.
[0025] Embodiment 2, use Figure 1-Figure 10 A straightening machine for pipes according to one embodiment of the present invention is described as follows.
[0026] like Figure 1-Figure 10As shown, a straightening machine for pipe fittings described in the present invention is based on the first embodiment, and the cleaning component 406 includes a cleaning plate 4061, the outer wall of the cleaning plate 4061 is rotatably connected to the inner wall of the dustproof box 404, and the central axis of the inner wall of the cleaning plate 4061 is rotatably connected to a rotating shaft 4062, and the outer wall of the rotating shaft 4062 is evenly provided with first curved rods 4063, and the inner wall of the first curved rod 4063 is fixedly connected to the outer surface of the rotating shaft 4062, and the end of the first curved rod 4063 away from the rotating shaft 4062 is rotatably connected to a first scraper 4064, and the outer surface of the first scraper 4064 contacts the inner wall of the cleaning plate 4061, and the first scraper 406 One end away from the first curved rod 4063 contacts the outer wall of the feeding roller 403, the outer wall of the rotating shaft 4062 is evenly provided with second curved rods 4065, the inner wall of the second curved rod 4065 is fixedly connected to the outer wall of the rotating shaft 4062, the second curved rod 4065 is staggered with the first curved rod 4063, one end of the second curved rod 4065 away from the rotating shaft 4062 is rotatably connected with the second scraper 4066, one end of the second scraper 4066 away from the rotating shaft 4062 contacts the outer wall of the grinding wheel 405, and the inner wall of the cleaning plate 4061 is symmetrically provided with limiting rods 4067, and the outer wall of the limiting rods 4067 is fixedly connected to the inner wall of the cleaning plate 4061.
[0027] The surface of the cleaning plate 4061 in contact with the grinding wheel 405 and the feeding roller 403 has a shape that conforms to the concave surface of the grinding wheel 405 and the feeding roller 403. The middle of the cleaning plate 4061 is convex, and the end in contact with the grinding wheel 405 and the feeding roller 403 is flat. After working for a period of time, the surfaces of the grinding wheel 405 and the feeding roller 403 are squeezed with the steel pipe, so that powdery debris such as cement ash is easy to agglomerate and adhere to the surfaces of the grinding wheel 405 and the feeding roller 403, resulting in the separation of debris between the feeding roller 403 and the grinding wheel 405 and the steel pipe, resulting in the deterioration of the shaping effect of the feeding roller 403 and the grinding effect of the grinding wheel 405. At this time, the cleaning plate 4061 rotates, and its two ends are placed on the surfaces of the feeding roller 403 and the grinding wheel 405 to scrape the feeding roller 403 and the grinding wheel 405. At this time, the rotating shaft 4062 keeps the first curved rod 4063 and the second curved rod 4065 inside the cleaning plate 4061, so that the first scraper 4064 and the second scraper 4066 are retracted in the cleaning plate 4061. When the debris cannot be cleaned by simple scraping, the driving source 2 drives the rotating shaft 4062 to rotate counterclockwise quickly, so that the first curved rod 4063 and the second curved rod 4065 move around the limiting rod 4067, and the first scraper 4064 and the second scraper 4066 are pushed outward, so that the first scraper 4064 and the second scraper 4066 contact and knock the outer surface of the grinding wheel 405 and the feeding roller 403, so that the pointed surfaces of the first scraper 4064 and the second scraper 4066 crush the cement powder and other debris, so that they fall off from the surface of the grinding wheel 405 and the feeding roller 403, and further cleaning is completed.

[0029] After the steel pipe is inserted into the pretreatment component 505 and the straightening component 506, it is continued to be pushed inward to make the steel pipe contact with the fixing plate 5031. Then the staff moves the U-shaped block 5035 and the connecting rod 5034 along the first slide 5032 and the second slide 5033 to the upper surface of the steel pipe, so that the arc rod 5036 surrounds the outer wall of the steel pipe. The arc rod 5036 is made of elastic material and has a large friction force. During the rotation of the bracket 502, due to the large gravity of the steel pipe and the long steel pipe, the end of the steel pipe in contact with the U-shaped block 5035 is easy to bend up during the rotation and lifting of the bracket 502, causing the steel pipe to fall off. At this time, the U-shaped block 5035 and the connecting rod 5034 are inside the first slide 5032 and the second slide 5033. Slide, and keep the U-shaped block 5035 always in contact with the steel pipe, the connecting rod 5034 is in the first slide 5032, and the U-shaped block 5035 slides in the second slide 5033. When the bracket 502 is gradually lifted, the steel pipe drives the connecting rod 5034 and the U-shaped block 5035 to move to the top of the first slide 5032, and the U-shaped block 5035 is separated from the second slide 5033, and then rotates 180 degrees around the connecting rod 5034, away from the steel pipe, and the arc rod 5036 is also away from the steel pipe, so that the steel pipe is in contact with the feeding roller 403, and enters the machine 1 with the help of the straightening component 506, so that the steel pipe completes autonomous feeding, avoiding the need to quickly evacuate after manually inserting the steel pipe into the machine 1, so as to avoid being pulled by the bent steel pipe and causing injury.

[0031] Initially, the worker inserts the steel pipe into the limit ring 5051 so that the grinding block 5055 contacts the outer wall of the steel pipe. After the bracket 502 is lifted to insert the steel pipe into the machine 1, the steel pipe is subjected to a force to move inward. As the steel pipe rotates continuously, the grinding block 5055 performs simple cleaning and grinding on the surface of the steel pipe under the rotation of the steel pipe, thereby reducing dust and debris on the surface, and reducing debris on the surface of the steel pipe entering the cleaning mechanism 4, thereby facilitating the maintenance of the cleanliness of the interior of the machine 1 and reducing the entry of debris. At the same time, the stability of the steel pipe is enhanced so that the steel pipe and the machine 1 are kept in a horizontal state before entering the cleaning mechanism 4.
[0032] The straightening assembly 506 includes a hydraulic rod 5061, the outer wall of the hydraulic rod 5061 is fixedly connected to the outer surface of the rotating plate 504, the end of the hydraulic rod 5061 away from the rotating plate 504 is fixedly connected to a straightening ring 5062, the inner wall of the straightening ring 5062 is evenly provided with moving rollers 5063, the outer wall of the moving roller 5063 is slidably connected to the inner wall of the straightening ring 5062, and the outer surface of the straightening ring 5062 is evenly provided with scrapers 5064, and the outer wall of the scraper 5064 is fixedly connected to the outer surface of the straightening ring 5062. Then, telescopic rods 5065 are evenly arranged on the side of the outer surface of the straightening ring 5062 away from the scraper 5064, and the outer wall of the telescopic rod 5065 is fixedly connected to the outer wall of the straightening ring 5062, and the end of the telescopic rod 5065 away from the straightening ring 5062 is fixedly connected to the adjusting ring 5066, and U-shaped rods 5067 are evenly arranged on the outer surface of the adjusting ring 5066, and the outer wall of the U-shaped rod 5067 is fixedly connected to the outer wall of the adjusting ring 5066, and the bottom of the U-shaped rod 5067 is in contact with the top of the scraper 5064.
[0033] Initially, the telescopic rod 5065 drives the adjusting ring 5066 away from the scraper 5064, and the scraper 5064 is elastic and keeps open. Then the worker inserts the steel pipe into the straightening ring 5062, and adjusts the position of the moving roller 5063 in the straightening ring according to the diameter of the steel pipe, so that the surface of the steel pipe fits the surface of the moving roller 5063. Then the telescopic rod 5065 contracts, driving the adjusting ring 5066 close to the straightening ring 5062, so that the scraper 5064 fits the surface of the steel pipe, and the cement blocks and dust on the surface of the steel pipe are removed. After the bracket 502 is lifted, the telescopic rod 5065 contracts to the tightest, so that the adjusting ring 5066 and the scraper 5064 are pressed tightly, thereby clamping the steel pipe, and then the hydraulic rod 5061 contracts inwards, driving the steel pipe to be inserted into the machine 1, and then the adjusting ring 5066 loosens the scraper 5064, so that the scraper 5064 just contacts the surface of the steel pipe. After the end of the steel pipe enters the machine 1, the steel pipe is pulled inward, and the hydraulic rod 5061 continues to move outward, so that the part of the steel pipe that has not entered the machine 1 is initially straightened by the hole in the middle of the straightening ring 5062, and the large debris on the surface of the steel pipe is initially cleaned to reduce the debris from entering the machine 1. The steel pipe is also reduced due to the large bending angle, so that when the steel pipe rotates, the bent part swings outward in a large range, which is easy to cause danger. At the same time, the steel pipe with a large bending angle is prevented from being stuck at the entrance of the machine 1 and affecting the straightening work.
[0034] The specific workflow is as follows: During operation, the machine 1 is turned on through the control console 6, and then the feeding mechanism 5 is turned on. Initially, the bracket 502 is placed flat on the ground, and the worker passes the steel pipe through the straightening component 506, and then passes it into the pretreatment component 505, and finally it is stuck on the limit component 503, and then the driving seat 501 is turned on, so that the driving seat 501 drives the bracket 502 to rotate. During the rotation of the bracket 502, the rotating plate 504 always keeps the pretreatment component 505 and the straightening component 506 in a horizontal state, so the steel pipe in the limit component 503 will rotate along the limit component 503, and finally when it is separated from the limit component 503, the steel pipe will be placed on the outside of the cleaning mechanism 4, and the straightening component 506 will push the steel pipe into the cleaning mechanism 4. The steel pipe is inserted into the machine 1 so that the head of the steel pipe enters the interior of the machine 1 and obtains initial power, so that the steel pipe rotates and enters the interior of the machine 1, and the tail end of the steel pipe is supported so that the position where the tail end is bent more can be initially straightened and adjusted. Then the feeding mechanism 5 inserts the steel pipe into the cleaning mechanism 4, and the surface of the steel pipe is cleaned inside the cleaning mechanism 4, so that cement and other debris attached to the steel pipe fall off and are discharged from the machine 1. Then the cleaned steel pipe enters the straightening mechanism 3 for correction. Driven by the straightening mechanism 3, the steel pipe rotates and enters the interior of the machine 1. During this process, the feeding mechanism 5 initially straightens and pre-cleans the place where the steel pipe is bent more, and finally the straightened steel pipe is taken out from the other side of the machine 1.
