Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, specifically to a steel clamping device for straightening steel bars and wires. Background Technology

[0002] The bar and wire cooling bed is a crucial step in the production process. After rolling, the finished bars need to be cooled naturally on the cooling bed. During production, if the temperature is not well controlled or affected by the ambient temperature, the ends of the bars on the cooling bed may bend. However, this bending of the ends of the bars will cause the following problems:

[0003] If the ends of the finished product are bent, it will affect the appearance quality and cause quality disputes.

[0004] Bending at the beginning and end of the finished product will reduce the yield and length accuracy, while a large amount of loss will increase processing costs.

[0005] Bending at both ends can affect the entire production rhythm during the fixed-length cutting process.

[0006] If the head and tail are bent, the device may pop out of the trough during collection, damaging the equipment and increasing safety risks.

[0007] Therefore, this utility model proposes a steel clamping device for bars that can quickly clamp and straighten the head and tail ends of bars when they are naturally cooled on a cooling bed, so as to avoid bending of the bars and prevent quality problems in the later stage. Utility Model Content

[0008] To address the aforementioned problems, this invention presents a steel clamping device for straightening bar wires.

[0009] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0010] A steel clamping device for straightening bar wire includes a base. The top wall of the base is provided with a support seat via a connecting seat 1. The bottom wall of the base is provided with a motor 1 on the left side. The output end of the motor 1 is locked with a drive shaft via a coupling. The outer wall of the drive shaft is rotatably connected to the outer wall of the base via a bearing 2. The top wall of the drive shaft is provided with a fixing mechanism. The outer wall of the fixing mechanism is provided with a connecting plate via a connecting block. The bottom wall of the connecting plate is provided with a top seat via a connecting seat 2.

[0011] Furthermore, the fixing mechanism includes a cylinder, a support column on the top wall of the cylinder, a groove on the left side of the inner wall of the support column, and a through hole on the right side of the outer wall of the support column. A second motor is provided on the inner bottom wall of the cylinder. A lead screw is rotatably connected to the upper and lower inner walls of the support column through a bearing, and the bottom end of the lead screw is fixedly connected to the output end of the second motor through a coupling. A circular plate is threaded onto the outer wall of the lead screw. A slider is provided on the left side wall of the circular plate. A support cylinder is provided on the top wall of the circular plate. A connecting block is provided on the right side of the outer wall of the support cylinder. The right end of the connecting block extends out of the through hole and is fixedly connected to the left side wall of the connecting plate.

[0012] Furthermore, the support cylinder has a hollow structure and is movably sleeved on the outer wall of the lead screw.

[0013] Furthermore, the outer ring of the second bearing is fixedly connected to the outer wall of the base through the bearing seat, and the inner ring of the second bearing is interference-fitted with the outer wall of the drive shaft.

[0014] Furthermore, the inner wall surface between the support base and the top base is arc-shaped and arranged vertically opposite each other.

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

[0016] The steel clamping device for bar and wire proposed in this utility model is closely integrated with the bar and wire cooling bed, intervening in straightening in real time during the bar cooling process. Its ingenious inverted L-shaped base design ensures a stable connection between the device and the cooling bed while providing reasonable space for bar transport and straightening. Through a motor-driven rotation and lifting mechanism, it can flexibly avoid the bar falling onto the bed and quickly achieve precise positioning after the bar is in place. The cooperation between the top seat and the support seat firmly clamps both ends of the bar, applying straightening force to the bent parts during relative movement, thus preventing bending at the ends of the bar from the root. This method of straightening simultaneously during the cooling stage effectively improves the appearance quality of the bar, avoiding quality disputes caused by bending; it reduces the large amount of cutting loss caused by bending at the ends, increases the yield and length-to-length rate, and lowers processing costs. Furthermore, the stable bar shape ensures smooth length-to-length shearing, optimizes the production rhythm, and prevents the bar from popping out of the groove during collection, reducing the risk of equipment damage and ensuring production safety. It provides an efficient, stable, and safe solution for bar production. 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figure 1-2 As shown, a steel clamping device for straightening bar wire includes a base 1. The top wall of the base 1 is provided with a support seat 3 via a connecting seat 2. The bottom wall of the base 1 is provided with a motor 4 on the left side. The output end of the motor 4 is locked with a drive shaft 5 via a coupling. The outer wall of the drive shaft 5 is rotatably connected to the outer wall of the base 1 via a bearing 2. The top wall of the drive shaft 5 is provided with a fixing mechanism. The outer wall of the fixing mechanism is provided with a connecting plate 16 via a connecting block 15. The bottom wall of the connecting plate 16 is provided with a top seat 18 via a connecting seat 2 17.

[0024] Furthermore, the fixing mechanism includes a cylinder 6, with a support column 7 on the top wall of the cylinder 6. A groove is formed on the left side of the inner wall of the support column 7, and an elongated hole 8 is formed through the right side of the outer wall of the support column 7. A motor 9 is mounted on the bottom inner wall of the cylinder 6. A lead screw 11 is rotatably connected to the upper and lower inner walls of the support column 7 via a bearing 10, and the bottom end of the lead screw 11 is fixedly connected to the output end of the motor 9 via a coupling. A circular plate 12 is threaded onto the outer wall of the lead screw 11. A slider 13 is provided on the left side wall of the circular plate 12, and a support is provided on the top wall of the circular plate 12. The support cylinder 14 has a connecting block 15 on the right side of its outer wall. The right end of the connecting block 15 extends out of the elongated hole 8 and is fixedly connected to the left side wall of the connecting plate 16. The top seat 18 is driven to rotate and move to the top of the support seat 3 by the motor 11. After the motor 2 is started, the lead screw 11 is rotated. The lead screw 11 causes the circular plate 12 to drive the slider 13, the support cylinder 14, the connecting block 15, the connecting plate 16, the connecting seat 2 17 and the top seat 18 to move downward. The top seat 18 moves downward and contacts the rod, pressing the rod onto the support seat 3.

[0025] Furthermore, the support cylinder 14 has a hollow structure and is movably sleeved on the outer wall of the lead screw 11. After the motor 2 9 is started, the lead screw 11 is rotated. The lead screw 11 causes the circular plate 12 to drive the slider 13, support cylinder 14, connecting block 15, connecting plate 16, connecting seat 2 17 and top seat 18 to move upward or downward conveniently.

[0026] Furthermore, the outer ring of the second bearing is fixedly connected to the outer wall of the base 1 through the bearing seat, and the inner ring of the second bearing is interference-fitted with the outer wall of the drive shaft 5. The second bearing fixes the drive shaft 5, making it easier for the drive shaft 5 to rotate through the second bearing.

[0027] Furthermore, the inner wall between the support seat 3 and the top seat 18 is arc-shaped and is arranged vertically opposite each other. When the bar arrives at the support seat 3 from the bar cooling bed, the top seat 18 is driven to rotate and move directly above the support seat 3 by motor 4. The top seat 18 is then driven to move downward and contact the bar by motor 9, pressing the bar tightly onto the support seat 3. The support seat 3 and the top seat 18 can move relative to each other and clamp and straighten the head and tail ends of the bar, thereby preventing the head and tail ends of the bar from bending and ensuring the quality of the bar.

[0028] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0029] One specific application of this embodiment is:

[0030] When in use, the vertical part of the inverted L-shaped base 1 is fastened to the preset mounting holes at both ends of the bar and wire cooling bed using high-strength bolts to ensure that the device and the cooling bed structure are stable and detachable, which facilitates later maintenance and adjustment. The horizontal part of the inverted L-shaped base 1 is designed to be lower than the upper surface of the bar and wire cooling bed, forming a sunken clearance space to avoid interfering with the normal conveying of the bar on the cooling bed.

[0031] Before the bar is conveyed, motor 4 is started in advance. Motor 4 drives shaft 5 through a coupling with a precisely matched transmission ratio, which drives the rotating assembly consisting of cylinder 6, support column 7 and connected connecting block 15, connecting plate 16, connecting seat 2 17 and top seat 18 to rotate 90° horizontally around support seat 3. At this time, top seat 18 rotates from directly above support seat 3 to the side clearance position, leaving an unobstructed passage for the bar to fall, ensuring that the bar can slide smoothly from the cooling bed to support seat 3.

[0032] After the bar accurately falls onto the support seat 3, motor 4 is started again to drive the rotating component to rotate in the opposite direction, so that the top seat 18 is accurately reset to directly above the support seat 3. Then motor 9 is started. The torque output by motor 9 is converted into vertical linear motion through high-precision lead screw 11, which drives the circular plate 12 threaded to lead screw 11 to rise and fall smoothly. Simultaneously, the pressing component composed of support cylinder 14, connecting block 15, connecting plate 16, connecting seat 17 and top seat 18 moves vertically downward.

[0033] During the descent, the elastic buffer layer at the bottom of the top seat 18 contacts the top surface of the bar. As the pressing assembly continues to descend, the top seat 18 gradually presses the bar onto the support seat 3. Both the support seat 3 and the top seat 18 are equipped with anti-slip teeth and pressure sensors (not shown in the figure). When the pressure reaches the preset straightening force threshold, the second motor 9 automatically stops running. The support seat 3 and the top seat 18 apply straightening force to both ends of the bar to prevent bending at both ends and ensure the quality of the bar. After straightening is completed, the second motor 9 reverses and drives the top seat 18 to rise and reset. The first motor 4 then rotates the top seat 18 away to facilitate the subsequent bar conveying and straightening cycle. The entire process is automated through mechatronics control, effectively avoiding bending at the ends of the bar and ensuring stable finished product quality.

[0034] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
