Description

Technical Field

[0001] The utility model relates to the technical field of bending devices, and more specifically, to a bending device for steel processing. Background Art

[0002] Steel is a material of a certain shape, size and performance made from ingots, billets or steel through pressure processing. Most steel processing is done through pressure processing, which causes plastic deformation of the processed steel.

[0003] When processing steel, operators often use corresponding bending devices. In actual use, although the existing bending devices can perform basic bending functions, they generally do not have the function of bending at a fixed angle. If the steel is bent at a fixed angle at this time, it is necessary to control the bending angle by manually controlling the movement of the turntable. This method is prone to over-bending and under-bending, affecting the subsequent effect of the steel, so it needs to be improved. Utility Model Content

[0028] Among them, the lifting mechanism includes a transmission motor 7, the bottom of the transmission motor 7 is fixedly connected to the bottom of the inner cavity of the working box 1, the other end of the output shaft of the transmission motor 7 is fixedly sleeved with a screw 8, the right side of the screw 8 is movably connected to the inner wall of the right side of the working box 1, the outer surface of the screw 8 is threadedly sleeved with a movable block 9, the top of the movable block 9 is hinged with a connecting rod 10, the other end of the connecting rod 10 is hinged with a rectangular block 11, the top of the rectangular block 11 is fixedly installed with a lifting rod 12, the outer surface of the lifting rod 12 is movably connected to the inner surface of the arc groove 6, and the lifting rod 12 moves upward to limit the rotation angle of the disc 4.

[0029] When the transmission motor 7 is running, the lead screw 8 will rotate and drive the movable block 9 to move to the right, thereby causing the connecting rod 10 to rotate and squeeze the rectangular block 11 to move upward, thereby causing the lifting rod 12 to move upward to limit the rotation angle of the disc 4, thereby achieving the purpose of fixed angle bending.

[0030] A round rod 13 located in front and behind the lead screw 8 is fixedly installed inside the working box 1 , and the outer surface of the round rod 13 is movably sleeved with the inner part of the movable block 9 .

[0031] The design of the round rod 13 serves to limit the movable block 9, so that the movable block 9 can move stably.

[0032] The inner walls on both sides of the working box 1 are provided with limiting grooves 19 , and the inner surfaces of the limiting grooves 19 are movably connected to the outer surfaces of the rectangular blocks 11 .

[0033] The design of the limiting groove 19 plays a role in limiting the rectangular block 11, so that the rectangular block 11 can move stably.

Then starting the drive motor 2 will cause the transmission shaft 3 to drive the disc 4 and the cylinder 5 to rotate, and the steel begins to bend under the action of the transmission shaft 3 and the cylinder 5. Finally, the top of the lifting rod 12 will block the rotation direction of the disc 4, thereby achieving the purpose of bending the steel at a fixed angle.
