[0011] Optionally, the central angle of the arc length of the locking module and the force rod on the outer ring of the bearing is 30-90 degrees.

[0012] Optionally, the locking module includes an elastic sleeve and a locking nut, the side wall of the elastic sleeve is fixedly connected to the rotating module, and the outer wall of the elastic sleeve is provided with an external thread that matches the thread of the locking nut.

[0013] Optionally, the height of the rotation axis of the guide support roller is lower than the height of the rotation axis of the rotation module.

The guide roller not only supports the round steel, but also guides the round steel to bend according to the predetermined path. By applying force to the guide roller on the force rod, the rotating module rotates toward one side of the guide roller. Under the action of the rotating force, the round steel slides from the guide roller to the rotating module, so that the round steel is made into an arc shape, forming an Ohm bend that meets the use requirements. It not only realizes the precise forming of the Ohm bend, but also significantly reduces the man-hours and manpower required for traditional manual production. By using this device, one person can easily complete it without other auxiliary tools, which greatly improves production efficiency.

[0019] The rotating module is used as a bearing, and the bearing itself has good load-bearing performance and can bear the radial and axial loads caused by the bending of round steel. The inner and outer rings of the bearing achieve relative rotation through rolling elements. The rolling friction method has a lower friction coefficient and higher rotation efficiency. The bearing can easily achieve smooth rotation under the action of the force rod, ensuring that the round steel can be bent according to the predetermined path, thereby achieving labor-saving operation. Within the angle range of 30-90 degrees, the force generated by the locking module and the force rod on the outer ring of the bearing is relatively evenly distributed, avoiding stress concentration caused by excessive or small angles, helping to increase the service life of the bearing, achieving multiple turnover uses, and also helping to make a larger arc length.

[0020] The design that the rotation axis of the guide roller is lower than the rotation axis of the rotating module makes the process of the round steel from the guide roller to the rotating module smoother and more labor-saving operation is possible. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In this embodiment, please refer to Figures 1 to 3 The utility model provides a labor-saving portable ohm bend processing device, including: a support mechanism 1, a guide mechanism 2 and a rotating mechanism 3, the support mechanism 1 includes a support plate 11, two V-shaped brackets 12, a first support arm 13 and a second support arm 14, the two V-shaped brackets 12 are arranged opposite to each other and both ends are fixedly connected to the support plate 11, forming a stable triangular support structure with high stability, capable of bearing a large load, ensuring that no shaking occurs during use, the first support arm 13 and the second support arm 14 are arranged opposite to each other and one end is vertically fixed to the support plate 11, the two V-shaped brackets 12, the first support arm 13 and the second support arm 14 are all located on the same surface of the support plate 11 and are arranged side by side, so that the center of gravity distribution of the entire support mechanism 1 is more reasonable, thereby enhancing the overall stability. and load-bearing capacity; the guide mechanism 2 includes a rotating shaft 21 rotatably mounted on the first support arm 13 and the second support arm 14 at both ends, and a guide support roller 22 coaxially fixedly matched with the rotating shaft 21. The surface of the guide support roller 22 is made of wear-resistant material, which can reduce the wear between the round steel and the guide support roller 22 and effectively extend the service life; the rotating mechanism 3 includes a rotating module 31, a force rod 32 and a locking module 33. The force rod 32 is fixedly mounted on the rotating module 31. The rotating module 31 rotates toward one side of the guide support roller 22 under the action of the force rod 32; the locking module 33 is fixedly connected to the rotating module 31 and is located at the rear end of the force rod 32 based on the rotation direction.

[0032] When in use, the round steel is tilted at an angle, one end of the round steel is placed on the guide roller 22, and the other end of the round steel is fixed by the locking module 33. The guide roller 22 not only supports the round steel, but also guides the round steel to bend according to a predetermined path. By applying a force toward the guide roller 22 to the force rod 32, the rotation module 31 rotates toward one side of the guide roller 22. Under the action of the rotation force, the round steel slides from the guide roller 22 to the side of the rotation module 31, so that the round steel is made into an arc shape, forming an ohm bend that meets the use requirements, which not only realizes the precise forming of the ohm bend, but also significantly reduces the man-hours and manpower required for traditional manual production. By using this device, a single person can easily complete it without other auxiliary tools, which greatly improves production efficiency. The finished ohm bends are uniform in size and have a consistent arc radius, which provides a guarantee for construction quality, thereby effectively preventing safety accidents such as hand injuries caused by improper operation of personnel.

[0033] In this embodiment, please refer to Figure 1 The rotating module 31 includes a bearing, both ends of the inner ring of the bearing are fixedly connected to the two V-shaped brackets 12, and the outer wall of the outer ring of the bearing is fixedly connected to the force rod 32. The rotating module 31 is a bearing, and the bearing itself has good load-bearing performance and can bear the radial and axial loads generated by the bending of the round steel. The inner and outer rings of the bearing realize relative rotation through rolling bodies. The rolling friction method has a lower friction coefficient and higher rotation efficiency. The bearing can easily realize smooth rotation under the action of the force rod 32, ensuring that the round steel can be bent according to the predetermined path, thereby realizing labor-saving operation.

[0034] In this embodiment, please refer to Figure 1 , the arc length of the locking module 33 and the force-adding rod 32 on the outer ring of the bearing subtends a central angle of 30-90 degrees. Within the angle range of 30-90 degrees, the force generated by the locking module 33 and the force-adding rod 32 on the outer ring of the bearing is relatively evenly distributed, avoiding stress concentration caused by an angle that is too large or too small, helping to increase the service life of the bearing, achieving multiple turnover uses, and also helping to make a circular arc with a larger arc length.

[0035] In this embodiment, please refer to Figure 1 The locking module 33 includes an elastic sleeve and a locking nut. The side wall of the elastic sleeve is fixedly connected to the rotating module 31. The outer wall of the elastic sleeve is provided with an external thread that matches with the thread of the locking nut. By passing the round steel through the elastic sleeve, the internal thread of the locking nut matches with the external thread on the outer wall of the elastic sleeve. The tightening force of the locking nut acts on the elastic sleeve, causing the elastic sleeve to deform, thereby tightly clamping the round steel and achieving reliable locking.

[0036] In this embodiment, please refer to Figure 1, the height of the rotation axis of the guide roller 22 is lower than the height of the rotation axis of the rotation module 31. The design that the rotation axis of the guide roller 22 is lower than the rotation axis of the rotation module 31 makes the round steel smoother from the guide roller 22 to the rotation module 31, thereby enabling labor-saving operation.

[0037] In this embodiment, please refer to Figure 2 The support plate 11 is provided with a weight-reducing groove 111. The design of the weight-reducing groove 111 makes it easy for construction workers to carry and transport. During the transportation process, not only can the support plate 11 be moved more easily, labor intensity is reduced, work efficiency is improved, and materials can be saved.

[0038] In this embodiment, please refer to Figure 2 or Figure 3 The guide roller 22 is provided with an annular roller groove 221 along the circumference of its outer wall. The design of the annular roller groove 221 enables the round steel to move more accurately along the predetermined direction, helps to prevent the round steel from shifting or deviating during the movement, and improves the accuracy and reliability of the guidance.

[0039] In this embodiment, the support mechanism 1 also includes a U-shaped frame, and the two ends of the U-shaped frame opening are fixedly connected to the top of the first support arm 13 and the second support arm 14 respectively, which can prevent the round steel from moving in the vertical direction and improve the safety of the entire device.

[0040] Working principle: When in use, the round steel is tilted at an angle, and the round steel passes through the annular roller groove 221 of the guide roller 22 and is inserted into the elastic sleeve. The internal thread of the locking nut cooperates with the external thread on the outer wall of the elastic sleeve. The tightening force of the locking nut acts on the elastic sleeve, causing the elastic sleeve to deform, thereby tightly clamping the round steel to achieve reliable locking. By applying a force toward the guide roller 22 to the force rod 32, the rotating module 31 rotates toward one side of the guide roller 22. Under the action of the rotating force, the round steel slides from the annular roller groove 221 on the guide roller 22 to the side of the rotating module 31, so that the round steel is made into an arc shape, forming an ohm bend that meets the use requirements, which not only realizes the precise forming of the ohm bend, but also significantly reduces the man-hours and manpower required for traditional manual production. By using this device, one construction worker can easily complete it, which greatly improves production efficiency. The finished ohm bends are uniform in size and have a consistent arc radius, which provides a guarantee for construction quality and avoids the occurrence of safety hazards.

The guide roller 22 not only supports the round steel, but also guides the round steel to bend according to a predetermined path. By applying a force toward the guide roller 22 to the force rod 32, the rotation module 31 rotates toward one side of the guide roller 22. Under the action of the rotation force, the round steel slides from the guide roller 22 to the side of the rotation module 31, so that the round steel is made into an arc shape, forming an ohm bend that meets the use requirements, which not only realizes the precise forming of the ohm bend, but also significantly reduces the man-hours and manpower required for traditional manual production. By using this device, a single person can easily complete it without other auxiliary tools, which greatly improves production efficiency. The finished ohm bends are uniform in size and have a consistent bending radius, which provides a guarantee for construction quality, thereby effectively preventing safety accidents such as hand injuries caused by improper operation of personnel; by using the rotation module 31 as a bearing, the bearing itself has good load-bearing performance and can bear the radial and axial loads generated by the bending of the round steel. The inner and outer rings of the bearing realize relative rotation through rolling elements. The rolling friction method has a lower friction coefficient and higher rotation efficiency. The bearing can easily realize smooth rotation under the action of the force rod 32, ensuring that the round steel can be bent according to the predetermined path, thereby realizing labor-saving operation. Within the angle range of 30-90 degrees, the force generated by the locking module 33 and the force rod 32 on the outer ring of the bearing is relatively evenly distributed, avoiding stress concentration caused by too large or too small angles, helping to increase the service life of the bearing, realizing multiple turnovers, and also helping to make a circular arc with a larger arc length; the design that the rotation axis of the guide roller 22 is lower than the rotation axis of the rotation module 31 makes the round steel smoother and smoother from the guide roller 22 to the rotation module 31, thereby realizing labor-saving operation.
