Description

Technical Field

[0001] This utility model relates to the field of cold-drawn tube technology, and in particular to a straightening device for cold-drawn tube production. Background Technology

[0002] Cold-drawn steel pipe is a type of steel pipe, classified according to different production processes, and is distinct from hot-rolled (expanded) pipe. It is produced through multiple cold-drawing processes during the expansion of the diameter of the blank or raw material pipe, typically on a single-chain or double-chain cold-drawing machine with a capacity of 0.5–100T.

[0003] Cold-drawn steel pipes undergo work hardening. During cold drawing, the metal undergoes plastic deformation, initiating multiple slip systems within the crystal. Dislocation movements intercept each other, many dislocations are pinned, resulting in dislocation pile-up, and dislocation sources cease operation. This series of processes reduces dislocation mobility and significantly increases the dislocation density in the crystal. As plastic deformation progresses, stress increases sufficiently to initiate movement of the pinned dislocations. Screw dislocations cross-slip, while edge dislocations cannot cross-slip, leading to dislocation intersection and increasing the immobility order.

[0004] Cold-drawn tubes may bend due to processing and environmental factors before and during production, requiring straightening before use. However, current straightening devices are inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems and deficiencies by proposing a straightening device for cold-drawn tube production: a laser generator is activated in conjunction with push rod two to adjust the height, and the laser beam is used to compare the tube. After push rod four is activated, the adjustment straightening seat and straightening roller contact the outer wall of the tube, and push rod four applies pressure to the tube to straighten it. This facilitates multi-point straightening and improves the accuracy of straightening.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A straightening device for cold-drawn tube production includes a base. The outer wall of the base has evenly spaced mounting holes at its center. The top outer wall of the base has evenly spaced straightening components at both ends. A mounting frame is mounted on one end of the outer wall of the base, and a bearing seat is mounted on one end of the mounting frame. A main shaft is mounted in the bearing seat, and a fixing component is mounted on one end of the main shaft. The straightening components include a mounting seat two mounted on the outer wall of the base, a push rod four mounted in the mounting seat two, a straightening seat mounted on the outer wall of one end of the push rod four, and straightening rollers rotatably connected to the outer walls of both ends of the straightening seat. The fixing component includes a fixing cylinder, mounting protrusions welded at equal intervals to the outer wall of the fixing cylinder, and fixing grooves opened on the inner wall of the fixing cylinder at the mounting protrusions.

[0008] Preferably, each of the inner walls of the fixing groove is equipped with a push rod three, and an arc-shaped plate is installed on the outer wall of one end of the push rod three, with a protective pad adhered to the inner and outer walls of the arc-shaped plate.

[0009] Preferably, a drive motor is mounted on the outer wall of the mounting bracket at one end of the main shaft, and the output shaft of the drive motor is connected to one end of the main shaft.

[0010] Preferably, a rolling seat is installed on the outer wall of one end of the base at the fixed cylinder, and the top outer wall of the rolling seat is rotatably connected to equally spaced support rollers, and the outer wall of one end of the fixed cylinder is rotatably connected to the outer wall of the support rollers.

[0011] Preferably, a push rod is installed in the inner wall of each mounting hole, and a support rod is installed on the outer wall of the top end of the push rod, with a support wheel rotatably connected to the outer wall of the top end of the support rod.

[0012] Preferably, a mounting base is installed at the center of the outer wall of the other end of the base, and a push rod is installed at one end of the mounting base, and a laser emitter is installed on the outer wall of the top end of the push rod.

[0013] Preferably, support legs are installed at both ends of the bottom outer wall of the base.

[0014] Preferably, the laser emitter, push rod two, push rod one, push rod three, push rod four, and drive motor are connected to a switch via wires, and the switch is connected to a power source via wires.

[0015] The beneficial effects of this utility model are as follows:

[0016] When the laser generator is started, the height is adjusted with push rod two. The laser beam is used to compare the pipeline. After push rod four is started, the adjustment correction seat and correction roller contact the outer wall of the pipeline. Push rod four applies pressure to the pipeline to correct it, which facilitates multi-point correction and improves the accuracy of correction.

[0017] The start-up drive motor drives the fixed cylinder to rotate via the main shaft. After the fixed cylinder rotates, it drives the pipe to rotate between the straightening rollers, adjusting the position of the pipe for easy straightening and use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1:

[0024] Reference Figure 1-4 A straightening device for cold-drawn tube production includes a base 1. The outer wall of the base 1 has evenly spaced mounting holes 2. The top outer wall of the base 1 has evenly spaced straightening components 6 at both ends. A mounting bracket 7 is installed on one end of the outer wall of the base 1, and a bearing seat 8 is installed on one end of the mounting bracket 7. A main shaft 9 is installed in the bearing seat 8, and a fixing component 11 is installed on one end of the main shaft 9. Support legs are installed on both ends of the bottom outer wall of the base 1. The base 1 is equipped with evenly spaced push rods 22 and 3, facilitating multi-point straightening and improving straightening accuracy.

[0025] The straightening assembly 6 includes a mounting base 21 installed on the outer wall of the base 1, a push rod 22 installed in the mounting base 21, a straightening seat 23 installed on the outer wall of one end of the push rod 22, and a straightening roller 24 rotatably connected to the outer walls of both ends of the straightening seat 23. After the push rod 22 on the mounting base 21 is started, it drives the straightening seat 23 and the straightening roller 24 to contact the pipeline, apply force to the pipeline for straightening, and facilitates straightening.

[0026] A mounting base 12 is installed at the center of the outer wall of the other end of the base 1, and a push rod 13 is installed at one end of the mounting base 12. A laser emitter 14 is installed on the outer wall of the top of the push rod 13. After the push rod 13 is started, it drives the laser emitter 14 to adjust its height. The beam of the laser emitter 14 is used as a reference for the pipeline to facilitate correction.

[0027] The laser emitter 14, push rod 2 13, push rod 1 3, push rod 3 17, push rod 4 22 and drive motor 10 are connected to a switch via wires, and the switch is connected to a power supply via wires. After the correction is completed, push rod 4 22 is started and the pipe is restricted between the correction seat 23 and the correction roller 24, which supports the area that has been corrected or the straight area and prevents the correction from affecting the straightness of the pipe. Example 2:

[0028] Reference Figure 2 and Figure 4 The fixing component 11 includes a fixing cylinder 15, mounting protrusions 16 welded at equal intervals to the outer wall of the fixing cylinder 15, and a fixing groove opened on the inner wall of the fixing cylinder 15 at the mounting protrusions 16. The drive motor 10 is started to drive the fixing cylinder 15 to rotate through the main shaft 9. After the fixing cylinder 15 rotates, it drives the pipe to rotate between the straightening rollers 24 to adjust the position of the pipe for easy straightening.

[0029] Push rods 17 are installed on the inner wall of the fixed groove, and an arc plate 18 is installed on the outer wall of one end of the push rod 17. A protective pad is glued to the inner and outer walls of the arc plate 18. When the push rod 17 is activated, the arc plates 18 move away from or closer to each other. After the inner and outer walls of one end of the arc plate 18 come into contact with the inner and outer walls of the pipe, one end of the pipe is fixed in the fixed cylinder 15.

[0030] A drive motor 10 is installed on the outer wall of the mounting frame 7 at one end of the main shaft 9, and the output shaft of the drive motor 10 is connected to one end of the main shaft 9. The drive motor 10 drives the fixed cylinder 15 to rotate on the mounting frame 7 through the main shaft 9. One end of the fixed cylinder 15 rotates and contacts the support roller 20 on the rolling seat 19, which facilitates support, rotation correction, and adjustment of the correction position.

[0031] A rolling seat 19 is installed on one end of the outer wall of the base 1 at the fixed cylinder 15, and the top outer wall of the rolling seat 19 is rotatably connected to the support rollers 20 distributed at equal intervals. One end of the outer wall of the fixed cylinder 15 is rotatably connected to the outer wall of the support rollers 20.

[0032] Push rod 3 is installed in the inner wall of each mounting hole 2, and support rod 4 is installed on the outer wall of the top of push rod 3. Support wheel 5 is rotatably connected to the outer wall of the top of support rod 4. Push rod 3 drives support rod 4 and support wheel 5 to rise. Support wheel 5 contacts the pipe for support, so that the pipe is parallel.

[0033] Working principle: In use, one end of the pipe to be corrected is inserted into the fixed cylinder 15. Activating push rod 3 17 moves the arc plates 18 closer or further apart. Once the inner and outer walls of one end of the arc plates 18 contact the inner and outer walls of the pipe, one end of the pipe is fixed in the fixed cylinder 15. Activating push rod 1 3 raises the support rod 4 and support wheel 5. The support wheel 5 contacts the outer wall of the pipe for support, working with the fixed cylinder 15 to support the pipe. The laser generator 14 is activated, and the height is adjusted using push rod 2 13. The laser beam is used as a reference for the pipe, and the push rods in the pipe bending area are activated. After push rod 422 is started, the adjusting straightening seat 23 and straightening roller 24 contact the outer wall of the pipe. Push rod 422 applies pressure to the pipe to straighten it. After the straightening is completed, push rod 422 starts and the pipe is restricted between the straightening seat 23 and straightening roller 24 to support the straightened area or the straight area and prevent the straightening from affecting the straightness of the pipe. The drive motor 10 is started and drives the fixed cylinder 15 to rotate through the main shaft 9. After the fixed cylinder 15 rotates, it drives the pipe to rotate between the straightening rollers 24 to adjust the position of the pipe for easy straightening.
