Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, and in particular relates to a device for correcting bending deformation of steel structures after heat treatment. Background Technology

[0002] Steel structures are widely used in bridges, buildings and machinery manufacturing. Their performance and precision directly affect the quality of the project. During the heat treatment process, steel is prone to deformation such as bending and twisting, and it needs to be repaired by a correction device before it can meet the requirements for use.

[0003] In existing calibration devices, the fixtures are mostly fixed structures. When processing workpieces of different specifications, it is necessary to change the fixtures or adjust the overall structure of the equipment. Furthermore, the clamping force cannot be guaranteed. Insufficient force can easily lead to workpiece displacement during calibration, while excessive force can cause workpiece damage, thus reducing the calibration accuracy of the steel structure.

[0004] To address this issue, we propose a device for correcting bending deformation during heat treatment of steel structures. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, most clamps are fixed structures and cannot maintain clamping force, and to propose a correction device for bending deformation of steel structures after heat treatment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A device for correcting bending deformation of steel structures after heat treatment includes a main frame. Two electric slide rails are fixedly connected to the inner wall of the main frame. Each electric slide rail has a sliding table slidably connected inside. A support block is fixedly connected to the upper surface of each sliding table. A first hydraulic rod is fixedly connected to the inner wall of each support block. An auxiliary block is fixedly connected to the telescopic end of each first hydraulic rod. A clamping block is slidably connected inside each auxiliary block. A pressure sensor is fixedly connected to the inner wall of each auxiliary block. A pressure-measuring spring is fixedly connected to the ends of two pressure sensors that are close to each other. The ends of two pressure-measuring springs that are close to each other are fixedly connected to the sides of the clamping blocks that are far from each other. A PLC controller is fixedly connected to the front of the main frame. The PLC controller is electrically connected to the electric slide rails, the first hydraulic rods, and the pressure sensors via wires.

[0007] Preferably, a second hydraulic rod is fixedly connected to the inner wall of the main frame, and a correction pressure head is fixedly connected to the telescopic end of the second hydraulic rod.

[0008] Preferably, the bottom surface of the main frame is fixedly connected to two sets of support columns, and the outer surface of each set of support columns is fixedly connected to a stabilizing ring.

[0009] Preferably, the main frame has multiple auxiliary slots arranged at equal intervals inside, and each auxiliary slot is rotatably connected to a sliding wheel.

[0010] Preferably, a retaining ring is fixedly connected to the outer surface of each of the first hydraulic rods, and the ends of the two retaining rings that are close to each other are fixedly connected to the sides of the support block that are far from each other.

[0011] Preferably, each of the two clamping blocks has an arc groove on one side that is close to each other, and a buffer pad is fixedly connected to the inner wall of each arc groove.

[0012] Preferably, each of the auxiliary blocks has two telescopic rods fixedly connected to its inner wall, and the ends of the two sets of telescopic rods that are close to each other are fixedly connected to the sides of the clamping block that are far from each other.

[0013] Preferably, the upper and lower surfaces of the PLC controller are fixedly connected with stabilizing blocks, and the back of each stabilizing block is fixedly connected to the front of the main frame.

[0014] In summary, the technical effects and advantages of this utility model are as follows: The system comprises a main frame, an electric slide rail, a slide table, a support block, a first hydraulic rod, an auxiliary block, a clamping block, a pressure sensor, a pressure-measuring spring, and a PLC controller. The electric slide rail moves the slide table and support block, changing the clamping position. The thrust generated by the first hydraulic rod pushes the auxiliary block, causing the clamping block to move simultaneously. When the clamping block contacts the steel structure, it moves inward due to pressure, causing the pressure-measuring spring to contract. The pressure sensor continuously monitors the pressure value generated by the pressure-measuring spring, and the PLC controller shuts off the first hydraulic rod when the pressure is appropriate, thus automatically clamping the steel structure. This system solves the problems of fixed fixtures requiring fixture replacement or overall equipment structure adjustment when processing workpieces of different sizes, and the inability to guarantee clamping force, which can lead to workpiece displacement due to insufficient force or damage due to excessive force. This system improves the accuracy of steel structure correction. Attached Figure Description

[0017] 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.

[0018] Reference Figure 1-4 A device for correcting bending deformation of steel structure after heat treatment includes a main frame 1. Two electric slide rails 2 are fixedly connected to the inner wall of the main frame 1. Each electric slide rail 2 has a sliding table 3 slidably connected inside. A second hydraulic rod 11 is fixedly connected to the inner wall of the main frame 1. A correction pressure head 12 is fixedly connected to the telescopic end of the second hydraulic rod 11. The power generated by the second hydraulic rod 11 pushes the correction pressure head 12 to continuously descend. The correction pressure head 12 is used to press on a designated position of the steel structure, thereby correcting its bending deformation.

[0019] Each slide 3 has a support block 4 fixedly connected to its upper surface, and a first hydraulic rod 5 fixedly connected to the inner wall of each support block 4. Two sets of support columns 13 are fixedly connected to the bottom surface of the main frame 1, and a stabilizing ring 14 is fixedly connected to the outer surface of each set of support columns 13. The support columns 13 can support the main frame 1, improve the stability of the main frame 1 during use, and the stabilizing ring 14 can increase the contact area between the support columns 13 and the ground.

[0020] Each first hydraulic rod 5 has an auxiliary block 6 fixedly connected to its telescopic end. Each auxiliary block 6 has a clamping block 7 slidably connected inside. The main frame 1 has multiple auxiliary slots 15 arranged at equal intervals inside. Each auxiliary slot 15 has a sliding wheel 16 rotatably connected inside. By using the cooperation of the auxiliary slots 15 and the sliding wheels 16, the movement of the steel structure inside the main frame 1 can be assisted, making it more sensitive during movement and reducing the fatigue of the operator.

[0021] Each auxiliary block 6 has a pressure sensor 8 fixedly connected to its inner wall. The ends of the two pressure sensors 8 that are close to each other are fixedly connected to a pressure measuring spring 9. Each first hydraulic rod 5 has a retaining ring 17 fixedly connected to its outer surface. The ends of the two retaining rings 17 that are close to each other are fixedly connected to the side of the support block 4 that is far away from each other. The retaining ring 17 can increase the fixed connection area between the first hydraulic rod 5 and the support block 4, making the connection between the two more secure, avoiding the possibility of breakage at the connection after long-term use, and increasing the durability of the device.

[0022] The ends of the two pressure springs 9 that are close to each other are fixedly connected to the sides of the clamping blocks 7 that are far apart from each other. The sides of the two clamping blocks 7 that are close to each other are provided with arc grooves 18. The inner wall of each arc groove 18 is fixedly connected with a buffer pad 19. The buffer pad 19 is made of silicone rubber material, which has high temperature resistance and elasticity. By relying on the cooperation of the buffer pad 19 and the arc groove 18, it can not only adapt to steel structure workpieces with different cross sections such as round tubes and square tubes, but also avoid scratching the surface of the workpiece during clamping.

[0023] A PLC controller 10 is fixedly connected to the front of the main frame 1. Two telescopic rods 20 are fixedly connected to the inner wall of each auxiliary block 6. The ends of the two sets of telescopic rods 20 that are close to each other are fixedly connected to the sides of the clamping block 7 that are far away from each other. The telescopic rods 20 can guide the movement direction of the clamping block 7, improve the uniformity of the clamping block 7 when subjected to force, and improve the effect of the device when in use.

[0024] The PLC controller 10 is electrically connected to the electric slide rail 2, the first hydraulic rod 5, and the pressure sensor 8 via wires. Stabilizing blocks 21 are fixedly connected to the upper and lower surfaces of the PLC controller 10. The back of each stabilizing block 21 is fixedly connected to the front of the main frame 1. The stabilizing rings 21 can increase the fixed connection area between the PLC controller 10 and the main frame 1, making the connection between the two more secure and preventing the PLC controller 10 from falling off after long-term use.

[0025] The working principle of this utility model is as follows: In use, firstly, the power supply to the first hydraulic rod 5, pressure sensor 8, PLC controller 10, and second hydraulic rod 11 is turned on. The steel structure to be corrected is then pushed into the main frame 1. The auxiliary groove 15 and sliding wheels 16 increase the ease of movement of the steel structure. When clamping the steel structure is required, the slide table 3 is adjusted to a suitable position using the electric slide rail 2, and the first hydraulic rod 5 is activated via the PLC controller 10. The first hydraulic rod 5 drives the auxiliary block 6 to move, and simultaneously moves the clamping block 7, causing the arc groove 18 and buffer pad 19 to contact the surface of the steel structure. At this time, due to the force... The clamping block 7 moves into the auxiliary block 6. The telescopic rod 20 increases the uniformity of the force on the clamping block 7 and causes the pressure measuring spring 9 to contract. The pressure sensor 8 monitors the current pressure value of the pressure measuring spring 9 and transmits the value to the PLC controller 10. When the pressure value equals the preset value, the PLC controller 10 shuts off the operation of the first hydraulic rod 5 through the wire, thereby completing the automatic fixation of the steel structure. Then, the second hydraulic rod 11 drives the correction pressure head 12 to descend, and the correction pressure head 12 is used to correct the steel structure. This effectively increases the applicability of the steel structure heat treatment bending deformation correction device.
