Description

Technical Field

[0001] This utility model belongs to the technical field of steel bar processing equipment, specifically relating to a straightening and traction fixing device for coiled steel bars. Background Technology

[0002] Wire rod, also known as coiled steel bar, is a commonly used steel product in construction engineering. It is manufactured in a continuous coiled state. In construction scenarios such as concrete component processing and on-site steel bar binding, it must first be straightened by straightening equipment to meet the dimensional and mechanical requirements of the component reinforcement.

[0003] Currently, most existing wire rod straightening equipment uses a fixed vertical support structure for the front-end traction and fixing. The fixed support is rigidly connected to the equipment base, which cannot adaptively adjust the angle according to the unwinding angle and feeding offset of the wire rod. Torsional stress is easily generated during the unwinding process of the wire rod, causing the wire rod to deviate during feeding. In addition, there is a lack of a targeted wire rod limiting and restraining structure, which makes the wire rod easy to fall off during feeding. At this time, manual handling is required, which reduces the continuity and stability of the straightening operation.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a wire rod straightening and traction fixing device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A straightening and traction fixing device for coiled steel bars, comprising: Base; A support column, the lower end of which is mounted on one end of the base along its length via a rotating mechanism, and a support beam provided in the upper middle part of the support column, the support beam extending upward and inclined toward the other end of the base; The rotating mechanism includes a rotating seat and a rotating body. The rotating body is rotatably connected inside the rotating seat, and the upper end of the rotating body is correspondingly fixed to the support column. Limiting grooves are provided on both sides of the rotating seat corresponding to the width direction of the base, and limiting strips extending into the limiting grooves are provided on both sides of the rotating body.

[0007] Preferably, the base is a square frame, and the lower surface of the base is provided with an anti-slip layer.

[0008] Preferably, the upper part of the support column is rotatably connected to a sleeve, and the sleeve is provided with diagonal braces on both sides of the base.

[0009] Preferably, a limiting rod is rotatably connected to the end of the supporting beam away from the supporting column, and the end of the limiting rod is provided with a constraint ring for the reinforcing bar to be straightened to pass through.

[0010] Preferably, the limiting groove is fan-shaped, and the angle of the corresponding fan shape is 20-30°.

[0011] Preferably, the inclination angle of the support beam is 10-20°.

[0012] Preferably, the support column is an I-beam, and ribs are provided between the support column and the support beam.

[0013] Beneficial effects: The rotating mechanism with a limiting structure allows the support column to rotate horizontally relative to the rotating seat through the rotating body. Combined with the angle limitation of the fan-shaped limiting groove, it can adaptively compensate for the angular deviation of the coiled steel bar, eliminate the torsional stress of the steel bar, prevent the support column from excessively deflecting, avoid feeding jamming and equipment shaking, and greatly improve the straightening accuracy of the steel bar.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0019] like Figure 1-3 As shown, a wire rod straightening and traction fixing device includes a base 1, a support column 2, a support beam 6, and a rotating mechanism 4. The lower end of the support column 2 is assembled to one end of the base 1 along its length through the rotating mechanism 4. The support beam 6 is fixedly installed in the upper middle part of the support column 2. The support beam 6 extends upward at an incline toward the other end of the base 1 to form an inclined feeding guide structure for installing wire rods.

[0020] The rotating mechanism 4 includes a rotating seat 401 and a rotating body 402. The rotating seat 401 is fixedly embedded or bolted into the mounting groove at the end of the base 1. The rotating body 402 is coaxially rotatably connected inside the rotating seat 401. The upper end face of the rotating body 402 is correspondingly fixed to the lower end face of the support column 2 by welding or flange bolt fastening, so that the support column 2 can rotate horizontally circumferentially relative to the rotating seat 401 with the rotating body 402.

[0021] The rotating seat 401 has symmetrically opened limit grooves 403 on both sides of the base 1 in the width direction. The two sides of the rotating body 402 are integrally formed or bolted with limit strips 404 that extend into the limit grooves 403. The limit strips 404 and the groove wall of the limit groove 403 are stopped and cooperated to limit the maximum rotation angle of the rotating body 402 and the support column 2, so as to prevent the support column 2 from excessively deflecting under the action of the steel bar traction force.

[0022] The limiting groove 403 is a fan-shaped groove structure. The center angle of the fan-shaped limiting groove 403 is 20°-30°. This angle range is the effective rotation adjustment range of the support column 2. It can not only meet the angle offset compensation requirements when the coiled steel bar is unwound, but also avoid the steel bar feeding path from being disordered due to excessive rotation angle.

[0023] In this embodiment, the base 1 is a rectangular frame steel structure, which is welded from channel steel and has a hollow rectangular frame structure. This reduces the overall weight while ensuring the load-bearing strength. The lower surface of the base 1 is fully covered with an anti-slip layer, which is made of wear-resistant rubber and is fixed by vulcanization bonding or bolt tightening. The bottom of the anti-slip layer has a mesh anti-slip texture to increase the friction coefficient between the base 1 and the ground and the equipment frame, thereby suppressing the overall slippage and vibration of the equipment during operation.

[0024] Furthermore, a sleeve 5 is rotatably connected to the upper middle part of the support column 2. The sleeve 5 is a wear-resistant seamless steel pipe. The support column 2 is preferably an I-beam. The outer diameter of the support column 2 is matched with the inner diameter of the seamless steel pipe, or the support column 2 is a round steel. A sliding bearing is installed between the sleeve 5 and the support column 2 to reduce relative rotational friction. Diagonal braces 3 are symmetrically arranged on both sides of the sleeve 5. The two ends of the diagonal braces 3 are respectively hinged to the outer wall of the sleeve 5 and the two side frames of the base 1 through hinge seats to form a triangular stable support structure, which shares the radial tensile force borne by the support column 2 and improves the deformation resistance of the support column 2.

[0025] In another embodiment, the end of the support beam 6 away from the support column 2 is rotatably connected to a limiting rod 7 via a bushing. The limiting rod 7 can rotate about the support beam 6. The length of the limiting rod 7 is not greater than the radius of the entire coil of steel bars corresponding to the wire rod. A constraint ring is fixedly provided at the end of the limiting rod 7. The constraint ring is a circular closed-loop structure. The inner diameter of the constraint ring is larger than the outer diameter of the steel bar to be straightened, so that the steel bar to be straightened can pass through it, thereby achieving radial limiting when the steel bar is fed and preventing the wire rod steel bar from falling off during the feeding process.

[0026] Furthermore, to prevent the reinforcing bars from falling off, the support beam 6 is tilted at an angle of 10°-20° relative to the upper surface of the base 1.

[0027] The support column 2 is preferably made of I-beam profile. By utilizing the structural advantages of the web and flange of the I-beam, the vertical compressive strength and radial torsional strength of the support column 2 are improved. Ribs are welded and fixed at the connection angle between the support column 2 and the support beam 6. The ribs are right-angled triangular steel plates. Multiple ribs are evenly distributed along the width of the support beam 6 to strengthen the connection stiffness between the support column 2 and the support beam 6 and prevent welding cracks or deformation at the connection due to long-term stress.

[0028] In actual operation, the end of the coiled steel bar is passed through the constraint ring and guided into the straightening equipment along the inclined support beam 6. During the unwinding process, the lateral traction force generated by the steel bar drives the rotating body 402 and the support column 2 to rotate adaptively within a 25° limit range, compensating for the unwinding angle deviation and eliminating torsional stress. The diagonal brace 3 and the rib plate work together to bear the tension and torsion, avoiding structural deformation. The bottom anti-slip layer inhibits the slippage of the equipment, ultimately achieving stable and high-precision straightening of the coiled steel bar.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
