Description

Technical Field

[0001] The invention belongs to the technical field of H-shaped steel processing, and in particular relates to an H-shaped thin-walled steel structure correction device. Background Art

[0002] H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Currently, the preparation methods of H-shaped thin-walled steel include welding and rolling.

[0003] The current production process of H-shaped thin-walled steel is prone to cause H-shaped thin-walled steel to produce different degrees of deformation. Common deformations include twisting deformation, upper and lower wing plate deformation, and upper arch bending deformation. These deformations not only affect the appearance quality of H-shaped thin-walled steel, but also affect its performance. Therefore, the production process of H-shaped thin-walled steel usually requires correction operations.

[0004] For the correction of wing plate deformation, the commonly used correction device is usually to use relatively set roller-shaped devices to reciprocate and roll the wing plate to make its surface flatness meet the requirements. However, since the thickness of H-shaped thin-walled steel is relatively thin, usually about 6mm-12mm, when rolling with rollers, the installation accuracy and movement accuracy requirements are relatively high. If the installation accuracy and movement accuracy do not meet the requirements, it is difficult to achieve a good correction effect. Summary of the invention

DETAILED DESCRIPTION

[0050] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention, and for ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0051] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the embodiments of the present invention are not therefore limited to the following embodiments.

[0052] Reference Figure 1-Figure 9 As shown, the present invention provides an H-shaped thin-walled steel structure correction device. The H-shaped thin-walled steel structure correction device of the present invention is arranged as a whole on a production platform, and includes a workbench 1, a correction mechanism 2 and a driving mechanism 3.

[0053] The workbench 1 includes a table 11 and a support leg 11a. The workbench 1 is used to place H-shaped thin-walled steel. Two correction mechanisms 2 are provided. The two correction mechanisms 2 are symmetrically arranged on both sides of the workbench 1. The two correction mechanisms 2 correct the wing plates on both sides of the H-shaped thin-walled steel on the workbench 1 from both sides. The driving mechanism 3 is located between the two correction mechanisms 3 and is used to drive the correction mechanism 2 to move and provide power for correcting the H-shaped thin-walled steel.

[0054] According to one embodiment of the present invention, the driving mechanism 3 of the present invention includes a driving cylinder 31, the driving cylinder 31 has a piston, and a wedge-shaped driving block 32 is connected to the front end of the piston rod. The width of the wedge-shaped driving block 32 gradually decreases in the direction away from the piston rod.

[0055] According to one embodiment of the present invention, the correction mechanism 2 of the present invention includes a fixed seat 4, which is fixed on the production platform, and the fixed seat 4 has a support groove 41, and the fixed platform 4 is in a "concave" shape as a whole. A transmission plate 5 is provided on the support groove 41, and the transmission plate 5 can slide on the support groove 41, and the support groove 41 plays a guiding and limiting role. The end face of the transmission plate 5 facing the wedge-shaped driving block 32 is an inclined surface 51 that cooperates with the wedge-shaped driving block 32. In this way, when the cylinder 31 drives the wedge-shaped driving block 32 to move forward, the wedge-shaped driving block 32 will gradually squeeze the inclined surface 51 to drive the transmission plate 5 to move outward. According to one embodiment of the present invention, a first correction plate 52 is fixedly connected to the transmission plate 5, and the first correction plate 52 is located on the inner side of the H-shaped thin-walled steel wing plate. When the transmission plate 5 moves outward, the first correction plate 52 moves with it to squeeze the H-shaped thin-walled steel wing plate.

[0056] In this embodiment, a correction guide groove 111 is provided on the lower side of the table 11 , and the first correction plate 52 has a sliding block 521 which is located in the correction guide groove 111 and slidably cooperates with the correction guide groove 111 .

The transmission plate 5 is provided with a second matching groove 53, and the second rotating shaft 925 is located in the second matching groove 72 and matches with the second matching groove 53. When the transmission plate 5 moves, the second rotating shaft 925 is driven to move in the second matching groove 72 to drive the hinge shaft 921 to rotate, and finally realizes the movement of the movable plate 7.

[0062] like Figure 1 As shown, in this embodiment, the end of the transmission plate 5 away from the wedge-shaped driving block 32 is connected to a reset structure 10, and the reset structure 10 includes a limit block 101 fixedly connected to the fixed seat 4, and the limit block 101 is located outside the transmission plate 5 and is spaced from the transmission plate 5.

[0063] The H-shaped thin-walled steel structure correction device of the present invention is provided with a reset structure so that the movable plate 5 compresses the elastic connecting member 103 during the forward movement of the wedge-shaped driving block 32. During the reset process of the wedge-shaped driving block 32 retreating, the movable plate 5 is also reset under the action of the elastic connecting member 103.

When a correction action is completed, the wedge-shaped driving block 32 begins to reset, the first correction plate 51 and the second correction plate 52 are respectively away from the H-shaped thin-walled steel wing plate, and at the same time, the thrust plate 17 moves backward, and the push plate 19 moves backward to contact the ratchet teeth of the ratchet wheel 15, driving the ratchet wheel 15 to rotate, thereby realizing the rotation of the roller shaft 13, and then driving the H-shaped thin-walled steel to move backward along the table 11.
