Description

Technical Field

[0001] This application relates to the technical field of angle steel processing, and in particular to an angle steel processing equipment and processing technology that resists bending. Background Technology

[0002] Angle steel, also known as angle iron, is a long strip of steel with two sides perpendicular to each other, forming an angle. Existing angle steel is made by bending rectangular steel plates, resulting in generally low bending strength. Current processing equipment can only achieve a simple bending effect, and the bent angle steel is prone to recovery deformation, affecting its final shape and thus product quality. Summary of the Invention

[0003] To reduce the recovery deformation of angle steel after bending, this application provides an angle steel processing equipment and processing technology that resists bending.

[0004] The bending-resistant angle steel processing equipment provided in this application adopts the following technical solution:

[0005] A bending-resistant angle steel processing equipment includes a bending mechanism and a welding mechanism. The bending mechanism includes a second workbench and a second support frame. The second support frame is fixed on the second workbench. A second hydraulic cylinder is fixed on the top of the second support frame. An upper mold is fixed on the piston rod of the second hydraulic cylinder. An installation groove is provided on the second workbench. The installation groove is arranged along the length direction of the second workbench. A lower mold is fixed in the installation groove.

[0006] The welding mechanism includes a third workbench, on which a third support frame is fixed. The length of the third support frame is arranged along the length of the third workbench. A welding gun is installed on the third support frame. The angle steel includes a first side plate and a second side plate that is perpendicular to and fixed to the first side plate. Multiple connecting rods are welded between the first side plate and the second side plate through the welding gun. The multiple connecting rods are evenly arranged along the length of the first side plate.

[0007] By adopting the above technical solution, when processing angle steel, the steel plate to be bent is first placed on the second workbench, and the upper mold is driven to move downward by the second hydraulic cylinder. Under the action of the upper mold and the lower mold, the steel plate is bent into angle steel. Then the angle steel is placed on the third workbench, and the connecting rod is welded to the first side plate and the second side plate by a welding gun, thereby increasing the strength of the angle steel and reducing the recovery deformation after bending.

[0008] Optionally, the second workbench is provided with a drilling mechanism away from the third workbench. The drilling mechanism includes a first workbench, on which a first support frame is fixed. A first hydraulic cylinder is fixed on the first support frame. A first mounting plate is fixed on the piston rod of the first hydraulic cylinder. Two drilling machines are fixed at the bottom of the first mounting plate. A steel plate to be bent is placed on the first workbench.

[0009] By adopting the above technical solution, when drilling holes in the steel plate to be bent, the steel plate to be bent is first placed on the first worktable, the first hydraulic cylinder drives the first mounting plate and the drilling machine to move downwards, and the drilling machine drills holes in the steel plate to be bent.

[0010] Optionally, a first positioning component is provided on the first workbench. The first positioning component includes two positioning plates. Each of the two positioning plates is rotatably connected to a threaded rod on the side away from each other. The end of the threaded rod away from the positioning plate passes through the side wall of the first support frame and is fixed with a handwheel. The steel plate to be bent is located between the two positioning plates. A second positioning component is provided on the second workbench. The structure of the second positioning component is the same as that of the first positioning component.

[0011] By adopting the above technical solution, when drilling holes in the steel plate to be bent, rotating the handwheel limits the installation plate, reducing the possibility of the steel plate shifting. The second positioning component limits the steel plate to be bent, thus enabling the upper mold to accurately bend the steel plate.

[0012] Optionally, a slider is fixed to the bottom of the positioning plate in the first positioning assembly, and a groove is provided on the first worktable for the slider to slide.

[0013] By adopting the above technical solution, when limiting the bending of the steel plate, the position of the positioning plate is moved by turning the handwheel. When the position of the positioning plate moves, the slider moves with the positioning plate in the groove, thereby increasing the stability of the positioning plate.

[0014] Optionally, a first insertion hole is provided on the first side plate, and a second insertion hole is provided on the second side plate. A first insertion rod is fixed to one end of the connecting rod near the first side plate, and the first insertion rod is inserted into the first insertion hole. A second insertion rod is fixed to one end of the connecting rod near the second side plate, and the second insertion rod is inserted into the second insertion hole.

[0015] By adopting the above technical solution, when welding the connecting rod, the connecting rod is placed between the first side plate and the second side plate, so that the first insert on the connecting rod is inserted into the first insertion hole, and the second insert on the connecting rod is inserted into the second insertion hole. Then, one end of the connecting rod is welded and fixed to the first side plate, and the other end of the connecting rod is welded and fixed to the second side plate, which facilitates the installation of the connecting rod.

[0016] Optionally, a motor is fixed to the side wall of the third support frame, and a lead screw and a second mounting plate are provided below the third support frame. The motor controls the rotation of the lead screw, which passes through the second mounting plate and is threadedly connected to it. A first cylinder is fixed to the bottom of the second mounting plate, and a third mounting plate is fixed to the piston rod of the first cylinder. A first mounting block is fixed to the bottom of the third mounting plate, and a second cylinder is fixed to the first mounting block. The piston rod of the second cylinder passes through the first mounting block and is fixed to the second mounting block. A welding torch is fixed to the bottom of the second mounting block, and the second cylinder can drive the second mounting block and the welding torch to move along the width direction of the third worktable.

[0017] By adopting the above technical solution, the motor drives the lead screw to rotate, and the lead screw drives the second mounting plate and the first cylinder to move along the length direction of the third worktable. The first cylinder can drive the third mounting plate and the first mounting block to move up and down, and the second cylinder on the first mounting plate can drive the welding gun to move along the width direction of the third worktable, thereby facilitating the welding gun to weld the connecting rod.

[0018] Optionally, reinforcing ribs are welded and fixed at the corners of the first side plate and the second side plate.

[0019] By adopting the above technical solution, the reinforcing rib increases the stability between the first side plate and the second side plate, and reduces the occurrence of recovery deformation after the angle steel is bent.

[0020] This application also provides a processing method for bending-resistant angle steel, including the following steps:

[0021] First, place the steel plate to be bent on the first workbench. Use two positioning plates to limit the two sides of the steel plate to be bent. Use the first hydraulic cylinder to drive the drill downward so that the drill can drill holes in the steel plate to be bent.

[0022] After drilling is completed, the steel plate to be bent is placed on the second workbench. The two positioning plates of the second positioning component limit the steel plate to be bent. The second hydraulic cylinder moves the upper mold downward. The steel plate is bent under the combined action of the upper mold and the lower mold.

[0023] The corners of the angle steel are fixed with reinforcing ribs. After the angle steel is formed, it is placed on the third workbench and the reinforcing ribs are welded by a welding machine.

[0024] Insert the first insert rod on the connecting rod into the first socket, insert the second insert rod on the connecting rod into the second socket, and weld the connecting rod to the angle steel by welding.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When processing angle steel, the steel plate to be bent is first placed on the second workbench. The upper mold is driven to move downward by the second hydraulic cylinder. Under the action of the upper mold and the lower mold, the steel plate is bent into angle steel. Then the angle steel is placed on the third workbench. The connecting rod is welded to the first side plate and the second side plate by the welding gun, thereby increasing the strength of the angle steel and reducing the recovery deformation after bending.
