Description

[0002] Bending is a process of heating steel pipes to a plastic state by medium-frequency current, mechanically bending and cooling to form, mainly used in the fields of building arc steel structure, tunnel support, roof beam and subway engineering, etc.

[0003] Common bending is mainly for I-beams and steel pipes, which is different from the structure of round pipes. The two U-shaped grooves of the I-beam need to be directed to the vertical direction, and the mechanical force is used to process the double-side bending of the side of the heat-treated I-beam. However, after the heat-treated I-beam is compressed by the mechanical force, the top and bottom protruding edges will be distorted. With the continuous cooling of the heat-treated I-beam and the action of internal stress, the inside of the protruding edge of the I-beam will be wrinkled. In severe cases, cracks will appear on the inside of the protruding edge. With the gradual increase of the bending angle, the distortion and wrinkling problems will be more serious.

[0031] The working principle and use process of the present application are as follows: four supporting frames 110 are fixedly installed on the workbench in advance, the first lead screw 1102 is adjusted according to the longitudinal height of the I-beam 500 to be processed, the beam plate 120 drives the whole forging edge alignment mechanism 300 to lift upward until the two top edge clamping seats 320 and the two bottom edge clamping seats 330 are adapted to the top and bottom of the I-beam 500 to be processed. Then the fourth lead screw 430 is adjusted to reverse, after the pulling piece 440 rises along the threaded section of the fourth lead screw 430, the two pull rods 450 movably installed on the pulling piece 440 are pressed to drive the two top edge clamping seats 320 to shrink, and the two upper clamping sleeves 3401 are pressed by the two third lead screws 350, and the two bottom edge clamping seats 330 connected by the two lower clamping sleeves 3402 also shrink inwardly, then one end of the I-beam 500 is inserted along the outside of the two top edge clamping seats 320 and the two bottom edge clamping seats 330, and the two bottom edge clamping seats 330 are stretched downward until the top and bottom of the I-beam 500 are adapted and pressed by the top edge clamping seats 320 and the bottom edge clamping seats 330. When the I-beam 500 is inserted into the above gap, the fourth lead screw 430 is adjusted to rotate again until the pulling piece 440 drives the two pull rods 450 to fall downward, and the two top edge clamping seats 320 pulled by the two pulling pieces 440 are adapted and pressed to the inner sides of the top and bottom of the I-beam 500 in cooperation with the two bottom edge clamping seats 330, then the two third lead screws 350 are adjusted to rotate again, at this time, the two third lead screws 350 will press the two upper clamping sleeves 3401 along the inside of the two top drawer plates 3203, and the two upper clamping sleeves 3401 will be pressed to the female plate 340 and the lower clamping sleeve 3402, and finally the four outer edge rollers 3404 will be adapted to bear pressure on the outer edge of the I-beam 500. In order to ensure the stability of the I-beam 500 bending, the two second lead screws 1502 are adjusted again, until the two second lead screws 1502 rotate clockwise, the two sliding blocks 1503 move along the threaded segments of the two second lead screws 1502 to approach the base 1301, at this time, the two supporting rods 1504 movably installed at both ends of the sliding block 1503 will pull the lower cross beam 3601 to shrink, and the lower cross beam 3601 assembled by the limiting column 3602 and the upper cross beam 360 will provide a stable support platform for the bearing roller 3604, and finally the four evenly distributed bearing rollers 3604 will provide pre-clamping protection for the I-beam 500 to be bent at the head and tail ends respectively. When the I-beam 500 needs to be bent at one end of the output direction; The motor 2301 is started, and the lengthened screw rod 220 driven by the motor 2301 will help the supporting plate 240 and the hydraulic part 2401 to move horizontally, until the sliding block 2403 moves to the inside of one of the plugs 2504, then the hydraulic part 2401 in operation will push the lower rail plate 2503 and the upper rail plate 2502 to perform a circular corner reverse around the end 2501, and finally the I-beam 500 after heat treatment can be bent according to its output direction. In order to control the angle of the I-beam 500 output end bending, the motor 2301 is controlled again, so that the supporting plate 240 carrying the hydraulic part 2401 slides along the sliding groove inside the lower rail plate 2503, until the supporting plate 240 and the hydraulic part 2401 approach the middle part of the base 1301, and as the hydraulic part 2401 approaches the center of the base 1301, the bending angle of the I-beam 500 output end will gradually increase. During the above-mentioned angle-adjusted bending process of the I-beam 500 output end, the forging edge alignment mechanism 300 can also provide straightening protection for the protruding edges on the top and bottom of the I-beam 500, to avoid distortion of the protruding edges of the I-beam 500 due to excessive bending pressure during the I-beam 500 bending operation.
