Description

Technical Field

[0001] This utility model relates to the field of positioning technology for straightening machines, and specifically to an automatic positioning device for straightening machines. Background Technology

[0002] Pipes can be solid or hollow, and they will bend to some extent during handling. Some slightly bent pipes can be straightened and reused. The existing straightening method generally involves fixing both ends of the bent pipe and straightening the bend in the middle with a pressure block.

[0003] Existing straightening equipment uses a method of fixing both ends of the pipe and applying pressure to the bend in the middle with pressure blocks to straighten it. However, in actual operation, as the straightening process progresses, axial movement occurs at both ends of the bend (e.g., Figure 6 As shown in the figure, the two ends of the pipe are fixed and cannot move axially, which may affect the straightening effect and efficiency. Specifically, the axial position adjustment is inaccurate, so the straightened pipe cannot be completely restored to a straight state.

[0004] Therefore, an automatic positioning device for a straightening machine is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic positioning device for a straightening machine in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An automatic positioning device for a straightening machine includes a frame and a straightening extrusion mechanism on the frame for straightening pipes. Guide rods are fixedly installed on the inner walls of both sides of the frame. The guide rods are movably equipped with an opening and closing mechanism. A position adjustment mechanism is provided on the frame. The movable part of the position adjustment mechanism is fixedly connected to the opening and closing mechanism for lateral movement of the opening and closing mechanism. Two sets of positioning components are provided on the opening and closing mechanism for pressing and positioning both ends of the pipe during straightening. The surface of the positioning component is provided with a groove, and a circular roller is rotatably installed in the groove.

[0008] Furthermore, the extrusion straightening mechanism includes an L-shaped bracket fixed on the frame, a bracket fixedly installed on the L-shaped bracket, a first hydraulic rod provided on the L-shaped bracket, and an extrusion plate fixedly installed through the movable part of the first hydraulic rod through the L-shaped bracket.

[0009] Furthermore, the position adjustment mechanism includes a first motor fixedly mounted on the frame, the output end of the first motor being fixedly connected to a one-way threaded rod, and two sets of movable blocks being threadedly sleeved on the one-way threaded rod, and the movable blocks being connected to the opening and closing mechanism.

[0010] Furthermore, the opening and closing mechanism includes two sets of mounting brackets that are slidably sleeved on the surface of the guide rod. The mounting brackets are fixed to the movable block. A second motor is fixedly mounted on the end face of one set of mounting brackets, and a bidirectional threaded rod is fixedly connected to the output end of the second motor.

[0011] Furthermore, the positioning assembly includes two sets of movable side plates that are slidably sleeved on the surface of the guide rod, and the two sets of movable side plates are threadedly sleeved on the surface of the bidirectional threaded rod. A second hydraulic rod is fixedly installed on the movable side plate, and the end of the second hydraulic rod is connected to an upper positioning plate. V-shaped positioning grooves are opened on the opposite surfaces of the movable side plate and the upper positioning plate, and a circular roller is rotatably installed in the groove on the surface of the V-shaped positioning groove.

[0012] Furthermore, a shaft flush with the surface of the V-shaped positioning groove is installed in the groove on the surface of the V-shaped positioning groove, and a circular roller is fixedly sleeved on the shaft, and the circular roller is rotatably installed with the shaft.

[0013] The beneficial effects of this utility model are as follows:

[0014] The opening and closing mechanism allows for adjustment between the two sets of positioning components, thereby adjusting the distance between them according to the length of the pipe to be straightened. The two sets of positioning components then fix and press the two ends of the pipe to be straightened. The position adjustment mechanism adjusts the position of the pipe to be straightened, allowing for adjustment of the position between the pipe to be straightened and the straightening extrusion mechanism. The straightening extrusion mechanism then performs the straightening operation on the pipe to be straightened. At this time, the pipe is under pressure, causing the two ends of the pipe to move axially. The circular rollers on the surface of the positioning components can adapt to the deformation and displacement of the two ends of the pipe. Attached Figure Description

[0026] like Figures 1 to 5As shown, an automatic positioning device for a straightening machine includes a frame 1 and a straightening extrusion mechanism 2 on the frame 1 for straightening pipes. Guide rods 3 are fixedly installed on the inner walls of both sides of the frame 1. Opening and closing mechanisms 5 are movably arranged on the guide rods 3. A position adjustment mechanism 4 is provided on the frame 1. The movable part of the position adjustment mechanism 4 is fixedly connected to the opening and closing mechanism 5 for lateral movement of the opening and closing mechanism 5. Two sets of positioning components 6 are provided on the opening and closing mechanism 5 for pressing and positioning at both ends when straightening the pipes. The surface of the positioning component 6 is provided with a groove and a circular roller 7 is rotatably installed in the groove. More specifically, the opening and closing mechanism 5 adjusts the distance between the two sets of positioning components 6 according to the length of the pipe to be straightened. The two sets of positioning components 6 then fix and press the two ends of the pipe to be straightened. The position adjustment mechanism 4 adjusts the position of the pipe to be straightened, and adjusts the position between the pipe to be straightened and the extrusion straightening mechanism 2. The extrusion straightening mechanism 2 then straightens the pipe. At this time, the pipe moves axially at both ends due to the pressure. The circular rollers 7 on the surface of the positioning components 6 can adapt to the deformation displacement of the two ends of the pipe.

[0027] The extrusion straightening mechanism 2 includes an L-shaped bracket 201 fixed on the frame 1, a bracket 202 fixedly mounted on the L-shaped bracket 201, a first hydraulic rod 203 provided on the L-shaped bracket 201, and an extrusion plate 204 fixedly mounted through the movable part of the first hydraulic rod 203. More specifically, the bracket 202 on the L-shaped bracket 201 supports the pipe to be straightened, and the first hydraulic rod 203 drives the extrusion plate 204 to move vertically downward, so that the extrusion plate 204 contacts the surface of the pipe to be straightened, thereby achieving vertical extrusion of the pipe and thus applying pressure to straighten the pipe.

[0028] The position adjustment mechanism 4 includes a first motor 401 fixedly mounted on the frame 1. A one-way threaded rod 402 is fixedly connected to the output end of the first motor 401. Two sets of movable blocks 403 are threaded onto the one-way threaded rod 402, and the movable blocks 403 are connected to the opening and closing mechanism 5. More specifically, the first motor 401 drives the one-way threaded rod 402 to rotate. Through the threaded connection between the movable blocks 403 and the one-way threaded rod 402, the opening and closing mechanism 5 is moved along the surface of the guide rod 3, enabling lateral movement of the pipe to be straightened.

[0029] The opening and closing mechanism 5 includes two sets of mounting brackets 501 that are slidably sleeved on the surface of the guide rod 3. The mounting brackets 501 are fixed to the movable block 403. A second motor 502 is fixedly mounted on the end face of one set of mounting brackets 501, and the output end of the second motor 502 is fixedly connected to a bidirectional threaded rod 503. More specifically, the second motor 502 drives the bidirectional threaded rod 503 to rotate, and the rotation of the bidirectional threaded rod 503 causes the two sets of positioning components 6 to move closer or further apart, thereby allowing adjustment of the distance between the two sets of positioning components 6.

[0030] The positioning assembly 6 includes two sets of movable side plates 601 that are slidably sleeved on the surface of the guide rod 3. The two sets of movable side plates 601 are threadedly sleeved on the surface of the bidirectional threaded rod 503. A second hydraulic rod 602 is fixedly installed on the movable side plate 601, and the end of the second hydraulic rod 602 is connected to an upper positioning plate 603. V-shaped positioning grooves 604 are formed on the opposite surfaces of the movable side plate 601 and the upper positioning plate 603. A circular roller 7 is rotatably installed in the groove on the surface of the V-shaped positioning groove 604. More specifically, by placing the two ends of the pipe to be straightened into the V-shaped positioning grooves 604 at the ends of the movable side plates 601, the upper positioning plate 603 is moved vertically downward by the second hydraulic rod 602, so that the V-shaped positioning grooves 604 on the surface of the upper positioning plate 603 fix and press the ends of the pipe to be straightened, thereby fixing the pipe to be straightened.

[0031] A shaft flush with the surface of the V-shaped positioning groove 604 is installed in the groove on the surface of the V-shaped positioning groove 604. A circular roller 7 is fixedly sleeved on the shaft, and the circular roller 7 is rotatably mounted to the shaft. More specifically, the circular roller 7, which is rotatably mounted on the shaft in the groove on the surface of the V-shaped positioning groove 604, allows the two ends of the pipe to be straightened to move axially after the ends of the pipe to be straightened are pressed and fixed.

[0032] In summary: The opening and closing mechanism 5 allows for adjustment between the two sets of positioning components 6, thereby adjusting the distance between them according to the length of the pipe to be straightened. The two sets of positioning components 6 then fix and press the two ends of the pipe to be straightened. The position adjustment mechanism 4 adjusts the position of the pipe to be straightened, allowing for adjustment of the position between the pipe to be straightened and the compression straightening mechanism 2. The compression straightening mechanism 2 then performs the straightening operation on the pipe to be straightened. At this time, the pipe is under pressure, causing the two ends of the pipe to move axially. The circular rollers 7 on the surface of the positioning components 6 can adapt to the deformation and displacement of the two ends of the pipe.
