Description

Technical Field

[0001] This utility model relates to the field of double-sided straightening machines, specifically a double-sided straightening machine for H-beam flanges. Background Technology

[0002] During the production of H-beams, welding is required. During the welding heating process, the flanges of the welded H-beams (or I-beams) bend and deform due to concentrated heat input. Therefore, they need to be straightened to ensure the processing quality of the H-beams.

[0003] In the prior art, such as in publication number CN217798186U, an H-beam straightening machine is disclosed. It includes a frame and a conveying mechanism mounted on the frame. Fixed seats are provided on both sides of the frame. A straightening roller is movably mounted on one side of each of the two fixed seats facing each other. The straightening roller can move up and down relative to the fixed seats. The straightening roller abuts against the flange on one side of the H-beam. Guide portions are provided on the one side of each of the two fixed seats facing each other for abutting against the two sides of the web of the H-beam respectively during straightening.

[0004] While the aforementioned patent effectively reduces the need to use grippers to flip the H-beam after straightening one flange and then straighten the other flange, its overall structure is complex and bulky, making it inconvenient for temporary straightening needs in construction scenarios and thus impractical. Furthermore, it cannot perform intelligent straightening operations based on the H-beam's dimensions, requiring manual parameter setting, which is inconvenient. Therefore, to address these issues, a double-sided straightening machine for H-beam flanges is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, which have relatively complex overall structures and large volumes, making them unsuitable for temporary straightening needs in construction scenarios and lacking practicality; furthermore, they cannot perform intelligent straightening operations based on the specifications and dimensions of H-shaped steel, requiring manual parameter setting and thus inconvenient operation, this utility model proposes a double-sided straightening machine for H-shaped steel flanges.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The double-sided straightening machine for H-shaped steel flanges of this utility model includes a left side plate and a right side plate. Mounting plates are fixedly connected to both ends of the left side plate and the right side plate. Placement blocks are fixedly connected to both sides of the left side plate and the right side plate. Pressure components are fixedly connected to both sides of the mounting plates and the placement blocks. Monitoring components are fixedly connected to the side of the placement blocks.

[0007] The pressure assembly includes a hydraulic push rod fixedly connected to the surface of the mounting plate and the placement block, and a pressure plate fixedly connected to their bottom ends.

[0008] The monitoring component includes a horizontal plate fixedly connected to the side of the placement block and an infrared sensor sleeved inside it. The infrared sensor is electrically connected to a control board, which is sleeved inside the equipment block.

[0009] Preferably, the hydraulic push rod of the pressure assembly includes two sets of hydraulic push rods that are respectively fixedly connected to the surfaces of the two mounting plates and the two sides of the placement block, and one end of each hydraulic push rod is fixedly connected to a pressure plate.

[0010] Preferably, the horizontal plate of the monitoring component is fixedly connected to the side of the placement block, the infrared sensor is vertically sleeved inside the horizontal plate, the control board is electrically connected to the infrared sensor, and the device block is fixedly connected to the side of the right side plate.

[0011] Preferably, the left side plate is provided with a connecting rod, and the right side plate is provided with a socket that mates with the connecting rod. The connecting rod is fixedly disposed on the left side plate, and the socket is opened on the right side plate and its shape is adapted to the cross-sectional shape of the connecting rod.

[0012] Preferably, the hydraulic push rods on the surface of the mounting plate include hydraulic push rods provided on the bottom surface of the top mounting plate and the top surface of the bottom mounting plate, and the hydraulic push rods on the surface of the placement block include hydraulic push rods provided on the top surface and the bottom surface of the placement block.

[0013] Preferably, the infrared sensor is configured as a symmetrical sensor group for detecting the inner spacing of the H-beam, and the control board is configured as an integrated controller for synchronously controlling the extension and retraction of the top and bottom hydraulic push rods according to the detection signal.

[0014] The advantages of this utility model are:

[0015] 1. This utility model achieves quick disassembly and positioning of the two side plates through the connecting rod and insertion hole structure set between the left and right side plates. Combined with the pressure components symmetrically distributed on both sides of the placement block and mounting plate, a modular correction unit is formed, which effectively reduces the overall volume and improves portability, enabling the equipment to adapt to the temporary correction needs of different construction scenarios and solving the problems of complex structure and inconvenient movement of traditional correction machines.

[0016] 2. This utility model uses an infrared sensor in the monitoring component to detect the inner spacing of the H-beam in real time, and combines it with the synchronous closed-loop control of the extension and retraction of the hydraulic push rod by the control board. This enables the pressure plate to dynamically correct the flange deformation of H-beams of different specifications, eliminates the operational error of manual parameter setting, improves the correction accuracy and efficiency, and solves the problems of traditional equipment relying on manual adjustment and having a low degree of intelligence.

[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. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, a double-sided straightening machine for H-beam flanges includes a left side plate 1 and a right side plate 2. Mounting plates 3 are fixedly connected to both ends of the left side plate 1 and the right side plate 2. Placement blocks 4 are fixedly connected to the sides of the left side plate 1 and the right side plate 2. Pressure components 5 are fixedly connected to both sides of the mounting plates 3 and the placement blocks 4. Monitoring components 6 are fixedly connected to the sides of the placement blocks 4. The pressure components 5 include hydraulic push rods 51 fixedly connected to the surfaces of the mounting plates 3 and the placement blocks 4 respectively, and pressure plates 52 fixedly connected to their bottom ends.

[0025] During operation, the left side plate 1 and the right side plate 2 are quickly positioned and installed by inserting the connecting rod 7 into the insertion hole. During operation, the two side plates are placed on both sides of the H-beam flange, so that the placement block 4 is embedded in the H-shaped groove at the end of the H-beam. At this time, the mounting plate 3 is located on the outer side of the upper and lower flanges of the H-beam. The hydraulic push rods 51 in the pressure assembly 5 are symmetrically distributed on the upper and lower surfaces of the mounting plate 3 and the top and bottom surfaces of the placement block 4. Through the modular split structure design, the equipment is lightweight and easy to carry, meeting the temporary straightening needs of the H-beam flange in different construction scenarios.

[0026] Furthermore, the monitoring component 6 includes a horizontal plate 61 fixedly connected to the side of the placement block 4 and an infrared sensor 62 sleeved inside it. The infrared sensor 62 is electrically connected to the control board 63, and the control board 63 is sleeved inside the device block 64.

[0027] During operation, the monitoring component 6 uses the infrared sensor 62 inside the horizontal plate 61 to detect the distance between the inner sides of the upper and lower flanges of the H-beam in real time. After receiving the distance signal, the control plate 63 synchronously adjusts the extension and retraction of the hydraulic push rods 51 on the bottom surface of the top mounting plate 3 and the top surface of the bottom mounting plate 3, so that the pressure plate 52 applies dynamic pressure to the flange. At the same time, the hydraulic push rods 51 on the top and bottom surfaces of the placement block 4 are synchronously linked to form a bidirectional symmetrical force application mode, realizing synchronous correction of the upper and lower flanges, eliminating the correction deviation caused by the error of manual parameter setting, and improving the accuracy of automatic control.

[0028] Furthermore, the left side plate 1 is provided with a connecting rod 7, and the right side plate 2 is provided with a socket that mates with the connecting rod 7. The connecting rod 7 is fixedly installed on the side of the left side plate 1, and the socket is opened on the side of the right side plate 2 and its shape is adapted to the cross-sectional shape of the connecting rod 7.

[0029] During operation, the connecting rod 7 fixed on the side of the left plate 1 and the insertion hole on the side of the right plate 2 are quickly connected by shape adaptation. During installation, the connecting rod 7 is inserted into the insertion hole to complete the mechanical locking of the two plates, so that the left plate 1 and the right plate 2 form a rigid frame that matches the width of the H-beam flange. This structure simplifies the equipment assembly process through the detachable connection design. At the same time, the precise fit between the insertion hole and the connecting rod 7 ensures that the two plates do not shift during the application of force, improves the stability of the straightening operation, and adapts to the straightening needs of H-beams of different specifications.

[0030] Furthermore, the infrared sensor 62 is configured as a symmetrical sensor group for detecting the inner spacing of the H-beam, and the control board 63 is configured as an integrated controller for synchronously controlling the telescopic movement of the top and bottom hydraulic push rods 51 according to the detection signal.

[0031] During operation, the infrared sensors 62 symmetrically arranged in the monitoring component 6 detect the distance between the inner sides of the upper and lower flanges of the H-beam in real time and transmit the distance signal to the control board 63 in the equipment block 64. The control board 63 synchronously adjusts the extension and retraction of the hydraulic push rods 51 on both sides of the mounting plate 3 and the placement block 4 according to the preset algorithm, so that the pressure plate 52 applies symmetrical and dynamically changing pressure to the flange. This closed-loop control system automatically matches the degree of deformation of the H-beam by real-time feedback of the correction amount, avoiding the problem of overpressure or underpressure caused by manual adjustment, realizing high-precision adaptive correction, and effectively improving the uniformity of flange flatness.

[0032] Working principle: The connecting rod 7 on the side of the left plate 1 is inserted into the insertion hole on the side of the right plate 2, so that the left plate 1 and the right plate 2 are fixed to both sides of the H-beam flange. The placement block 4 is embedded in the H-shaped groove at the end of the H-beam. The infrared sensor 62 in the horizontal plate 61 of the monitoring component 6 detects the distance between the inner sides of the upper and lower flanges of the H-beam in real time and transmits the signal to the control board 63 in the equipment block 64. The control board 63 drives the hydraulic push rods 51 on the surface of the mounting plate 3 and both sides of the placement block 4 to extend and retract according to the distance data. The hydraulic push rods 51 on the bottom surface of the top mounting plate 3 and the hydraulic push rods 51 on the top surface of the placement block 4 push the pressure plate 52 to press the upper flange of the H-beam. The hydraulic push rods 51 on the top surface of the bottom mounting plate 3 and the hydraulic push rods 51 on the bottom surface of the placement block 4 drive the pressure plate 52 to press the lower flange, forming a bidirectional symmetrical extrusion action. The dynamic correction of the deformation of the H-beam flange is achieved through closed-loop feedback adjustment.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
