Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, and in particular to a round pipe straightening machine. Background Technology

[0002] As a fundamental material widely used in construction, machinery, energy, and other fields, the straightness of round tubes is one of the core indicators for measuring product quality. In the round tube processing flow, the round tube sorting process is a crucial step, aiming to ensure that round tubes entering subsequent processes such as cutting, welding, and bending meet straightness requirements through inspection and screening. Round tubes that fail to pass sorting need to undergo a straightening process to eliminate deformation and restore their geometric accuracy. However, the traditional round tube straightening process generally requires manual handling of each round tube to be straightened onto the straightening machine's workbench, manual positioning, and then starting the equipment for straightening. After completion, manual unloading and stacking are required. This process is time-consuming and limited by the operator's physical strength and skill, making it difficult to match the cycle time of a high-speed sorting system, resulting in low efficiency and hindering the high-efficiency processing requirements of round tubes. Therefore, there is an urgent need for a round tube straightening machine with efficient automatic feeding, automatic straightening, and automatic unloading functions. Utility Model Content

[0003] The purpose of this invention is to provide a round tube straightening machine to solve the problems of long processing time and low efficiency of manual operation in the existing round tube straightening process.

[0004] The present invention provides the following technical solution: a round tube straightening machine, comprising a frame, a feeding mechanism, a transfer mechanism, a straightening mechanism, and a unloading mechanism disposed on the frame. The straightening mechanism is located between the feeding mechanism and the unloading mechanism. The transfer mechanism includes a transfer platform and a lifting frame. The transfer platform is reciprocally disposed between the feeding mechanism and the unloading mechanism. The lifting frame is movably disposed on the transfer platform along the height direction. The lifting frame is provided with a first tube-holding area and a second tube-holding area. When the lifting frame rises, the first tube-holding area picks up the tube material located at the feeding mechanism, and the second tube-holding area picks up the tube material located at the straightening mechanism. At this time, the transfer platform moves closer to the unloading mechanism, causing the first tube-holding area to move to the straightening mechanism and the second tube-holding area to move to the unloading mechanism. At this time, the lifting frame descends, placing the tube material placed in the first tube-holding area onto the straightening mechanism and the tube material placed in the second tube-holding area onto the unloading mechanism.

[0005] As described above, in a round tube straightening machine, the transfer mechanism further includes transfer frame plates arranged opposite to each other on both sides of the lifting frame. The upper side of each transfer frame plate is recessed with a first mounting portion and a second mounting portion. A first tube mounting area is formed between the first mounting portions on the opposite transfer frame plates, and a second tube mounting area is formed between the second mounting portions on the opposite transfer frame plates. The feeding mechanism includes feeding frame plates arranged opposite to each other, and the unloading mechanism includes an unloading plate. A clearance opening is provided on the side of the unloading plate near the transfer table. The first tube mounting area can be moved between the feeding frame plates to pick up the tube material, and the second tube mounting area can be moved into the clearance opening to unload the tube material.

[0006] As described above, the round tube straightening machine includes a feeding mechanism that further includes a material box, a feeding component that is movably connected to the bottom of the material box, and a feeding driver that drives the feeding component to rise and fall. The end of the feeding frame plate is recessed with a feeding part corresponding to the first frame tube area. When the feeding component descends, the tube material in the material box rolls to the top of the feeding component. When the feeding component rises, it drives the tube material to rise to the edge of the opening of the material box, so that the tube material leaves the material box and falls into the feeding part.

[0007] As described above, in a round tube straightening machine, the unloading plate has unloading contact surfaces on both sides of the clearance opening, which are corresponding to the second frame tube area. The unloading contact surfaces are inclined towards the side away from the transfer table. When the second frame tube area moves to the clearance opening and the lifting frame descends, the unloading contact surfaces abut against both ends of the tube material, causing the tube material to detach from the second frame tube area.

[0008] As described above, a round tube straightening machine includes a straightening frame, a rotation adjuster, and a straightening pressure head located between the opposing straightening frames. The rotation adjuster includes a rotatable abutment wheel that rotatably abuts against the tube on the straightening frame to drive the tube to rotate around its axis. The straightening pressure head is movably arranged in a direction close to or away from the tube. When the lifting frame descends, the straightening frame can be used to receive the tube located in the first tube area. When the lifting frame rises, the second tube area receives the tube located on the straightening frame.

[0009] As described above, in a round tube straightening machine, the rotation regulator further includes a wheel lifter, which is used to drive the abutment wheel closer to or further away from the tube.

[0010] As described above, in a circular tube straightening machine, the straightening frame is recessed with an arc-shaped groove, and the surface of the groove is smooth.

[0011] As described above, in a circular tube straightening machine, the straightening pressure head includes buffer blocks disposed opposite each other and a pressure roller located between the opposite buffer blocks, the pressure roller protruding between the buffer blocks.

[0012] In the circular tube straightening machine described above, the pressure roller is made of a hard material.

[0013] In the circular tube straightening machine described above, the buffer block is made of an elastic material.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This utility model discloses a round tube straightening machine, which is equipped with a feeding mechanism, a transfer mechanism, a straightening mechanism, and a unloading mechanism on the frame. The transfer mechanism uses a reciprocating transfer table and a lifting frame to achieve rapid feeding between the feeding mechanism and the straightening mechanism, as well as rapid unloading between the straightening mechanism and the unloading mechanism. Specifically, a first tube rack and a second tube rack are set on the lifting frame. The transfer mechanism completes the transportation of the tube to be straightened from the feeding mechanism to the straightening mechanism through a cyclic action of "lifting frame rising - transfer table moving - lifting frame falling - transfer table resetting". At the same time, the second tube rack completes the transportation of the straightened tube from the straightening mechanism to the unloading mechanism. This significantly shortens the processing flow of the straightening equipment for round tubes and greatly improves the processing efficiency of round tubes. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to the appendix Figure 1 To be continued Figure 5This embodiment provides a round tube straightening machine, including a frame 1, a feeding mechanism 2, a transfer mechanism 3, a straightening mechanism 4, and a unloading mechanism 5 mounted on the frame 1. The straightening mechanism 4 is located between the feeding mechanism 2 and the unloading mechanism 5. The transfer mechanism 3 includes a transfer platform 31 and a lifting frame 32. The transfer platform 31 is reciprocating between the feeding mechanism 2 and the unloading mechanism 5. The lifting frame 32 is movably mounted on the transfer platform 31 along the height direction. The lifting frame 32 is provided with a first tube support area 321 and a second tube support area 32. 2. When the lifting frame 32 rises, the first pipe section 321 picks up the pipe material located on the feeding mechanism 2, and the second pipe section 322 picks up the pipe material located on the calibration mechanism 4. At this time, the transfer table 31 moves closer to the unloading mechanism 5, so that the first pipe section 321 moves to the calibration mechanism 4 and the second pipe section 322 moves to the unloading mechanism 5. At this time, the lifting frame 32 descends, so that the pipe material on the first pipe section 321 is placed on the calibration mechanism 4 and the pipe material on the second pipe section 322 is placed on the unloading mechanism 5. The round tube straightening machine of this embodiment is equipped with a feeding mechanism 2, a transfer mechanism 3, a straightening mechanism 4, and an unloading mechanism 5 on the frame 1. The transfer mechanism 3 adopts the cooperation of a reciprocating transfer table 31 and a lifting frame 32, which realizes rapid feeding between the feeding mechanism 2 and the straightening mechanism 4, and rapid unloading between the straightening mechanism 4 and the unloading mechanism 5. Specifically, a first tube area 321 and a second tube area 322 are set on the lifting frame 32. The transfer mechanism 3 completes the transportation of the tube to be straightened from the feeding mechanism 2 to the straightening mechanism 4 through the cyclic action of "lifting frame 32 rising - transfer table 31 moving - lifting frame 32 falling - transfer table 31 resetting". At the same time, the second tube area 322 completes the transportation of the straightened tube from the straightening mechanism 4 to the unloading mechanism 5. This greatly shortens the processing flow of the straightening equipment for round tubes and greatly improves the processing efficiency of round tubes.

[0024] The transfer mechanism 3 also includes transfer frame plates 33 arranged opposite to each other on both sides of the lifting frame 32. The upper side of each transfer frame plate 33 is recessed with a first mounting part 331 and a second mounting part 332. A first tube mounting area 321 is formed between the first mounting parts 331 on the opposite transfer frame plates 33, and a second tube mounting area 322 is formed between the second mounting parts 332 on the opposite transfer frame plates 33. The feeding mechanism 2 includes a feeding frame plate 21 arranged opposite to each other, and the unloading mechanism 5 includes an unloading plate 51. A clearance opening 511 is opened on the side of the unloading plate 51 near the transfer table 31. The first tube mounting area 321 can be moved between the feeding frame plates 21 to pick up the tube material, and the second tube mounting area 322 can be moved into the clearance opening 511 to unload the tube material. Specifically, when the first pipe section 321 moves between the feeding rack plates 21, the second pipe section 322 moves to the calibration mechanism 4. At this time, during the lifting process of the lifting frame 32, the height of the first mounting part 331 gradually rises to a height higher than the transfer rack plate 33 to pick up the pipe material to be calibrated on the transfer rack plate 33. At the same time, the height of the second mounting part 332 gradually rises to a height higher than the calibrating height of the calibration mechanism 4 to pick up the calibrated pipe material located on the calibration mechanism 4. When the second pipe section 322 moves to the clearance port 511, the first pipe section 321 moves to the calibration mechanism 4. At this time, during the lowering process of the lifting frame 32, the height of the second mounting part 332 gradually decreases to a height lower than the height of the unloading plate 51 located on both sides of the clearance port 511, so that the calibrated pipe material is pushed out of the second mounting part 332 to complete the unloading. At the same time, the height of the first mounting part 331 gradually decreases to a height lower than the calibrating height of the calibration mechanism 4, so that the pipe material to be calibrated is mounted on the calibration station of the calibration mechanism 4 for calibration.

[0025] The feeding mechanism 2 also includes a material box 22, a feeding component 23 movably connected to the bottom of the material box 22, and a feeding driver 24 that drives the feeding component 23 to rise and fall. The end of the feeding frame plate 21 is recessed with a feeding part 211 corresponding to the first tube area 321. When the feeding component 23 descends, the tube material in the material box 22 rolls to the top of the feeding component 23. When the feeding component 23 rises, it drives the tube material to rise to the edge of the opening of the material box 22, so that the tube material leaves the material box 22 and falls into the feeding part 211. Under the reciprocating drive of the feeding driver 24, the feeding component 23 can continuously transport the tube material to the feeding part 211, which facilitates the cyclical picking of the first tube area 321.

[0026] The unloading plate 51 has unloading abutment surfaces 512 on both sides of the clearance opening 511, corresponding to the second frame pipe area 322. The unloading abutment surfaces 512 are inclined towards the side away from the transfer table 31. When the second frame pipe area 322 moves to the clearance opening 511 and the lifting frame 32 descends, the unloading abutment surfaces 512 abut against both ends of the pipe, causing the pipe to detach from the second frame pipe area 322. The setting of the unloading abutment surfaces 512 allows the aligned pipe to roll naturally on the unloading mechanism 5 along the inclined direction of the unloading abutment surfaces 512 towards the direction away from the transfer table 31 when it is pushed out of the second frame part 332 by the unloading plate 51, which facilitates the collection of the pipe after unloading.

[0027] The calibration mechanism 4 includes a calibration platform 41, a rotation adjuster 42, and a calibration pressure head 43 located between the opposing calibration platforms 41. The rotation adjuster 42 includes a rotatable abutment wheel 421, which rotatably abuts against the pipe material located on the calibration platform 41 to drive the pipe material to rotate around its axis. The calibration pressure head 43 is movably positioned in the direction of approaching or moving away from the pipe material. When the lifting frame 32 descends, the calibration platform 41 can be used to receive the pipe material located in the first pipe section 321. When the lifting frame 32 rises, the second pipe section 322 receives the pipe material located on the calibration platform 41. The rotation adjuster 42 uses an abutment wheel 421 that can drive the pipe material to rotate, so that the calibration point of the pipe material is aligned with the calibration pressure head 43, thereby achieving flexible calibration of the calibration point of the pipe material.

[0028] The self-rotation regulator 42 also includes a rotary wheel lifter 422, which is used to drive the abutment wheel 421 to approach or move away from the pipe. The rotary wheel lifter 422 facilitates the engagement or disengagement of the abutment wheel 421 with the pipe. When the engagement is disengaged, it provides clearance for the second pipe support area 322 during the lifting process of the pipe.

[0029] The calibration stand 41 is recessed with an arc-shaped groove 411. The surface of the groove 411 is smooth to reduce friction between the pipe and the groove 411 during the self-rotation adjustment process and to protect the pipe.

[0030] The calibration head 43 includes opposing buffer blocks 431 and a pressure roller 432 located between the opposing buffer blocks 431, with the pressure roller 432 protruding between the buffer blocks 431. The pressure roller 432 is used to press against the pipe material to achieve calibration of the pipe material.

[0031] Preferably, the pressure roller 432 is made of a hard material.

[0032] Preferably, the buffer block 431 is made of an elastic material.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
