Description

Technical Field

[0001] The utility model relates to plate bending equipment, in particular to a plate edge bending device. Background Art

[0002] Sheet metal processing often involves processes such as trimming, bending, cutting, and polishing. Sheet metal bending refers to the process of changing the angle of a sheet metal or sheet metal part as needed, such as bending the sheet metal into a V-shape, a U-shape, etc., and then processing it into workpieces such as square tubes.

[0003] For example, the plate edge bending device disclosed in Chinese patent CN221537718U uses a lifting member to drive the raising and lowering of the protrusion, which can make the plate tilt at a certain angle, and then uses a hydraulic member to drive the bending mold to descend, and the protrusion is provided with a through-hole groove on the top surface of the workbench to slide, so as to facilitate the adjustment of the size to be bent.

[0004] In the above patent, when bending the edge of the plate, the plate is moved by the loading structure, but the loading structure does not fix the plate, causing the plate to shift during the movement, which in turn affects the quality of the plate bending.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0006] In response to the problems in the related art, the present invention proposes a plate edge bending device to overcome the above technical problems existing in the existing related art.

[0007] To this end, the specific technical solutions adopted in this utility model are as follows:

[0008] The adjusting screw mandrel is fixed with a fixing block and is fixed with the fixing block, and the fixing block is fixed with the fixing block.

[0009] Furthermore, in order to facilitate the rotation of the screw, the drive assembly includes a side box fixedly connected to the side wall of the frame, a drive shaft is rotatably connected inside the side box, and second bevel gears are fixedly installed at both ends of the drive shaft. One end of the drive shaft extends outside the side box and is connected to the output end of the feeding motor.

[0010] Furthermore, in order to facilitate the rotation of the screw rod along with the driving shaft, the threaded rotating rod extends into the side box and is fixedly connected to the first bevel gear, and the first bevel gear is meshed with the second bevel gear.

[0011] Furthermore, in order to make the bending block slide stably in the bending groove, sliding grooves are opened on both ends of the inner surface of the bending groove, and sliding blocks are fixedly connected to both ends of the outer surface of the bending block, and the sliding blocks are slidably connected to the sliding grooves.

[0012] Furthermore, in order to facilitate the movement of the bending block, a transverse plate is fixedly connected to the bottom end of the frame, a cylinder is fixedly installed at the center of the transverse plate, and an output end of the cylinder is fixedly connected to the bending block.

[0013] Furthermore, in order to prevent the plate from moving during the bending process, a top plate is fixed on the top of the frame, and a hydraulic cylinder is symmetrically installed on the top plate. The output end of the hydraulic cylinder passes through the top plate and is fixedly connected to the lower pressure block. A bidirectional screw rod is rotatably connected inside the lower pressure block, and a stop block is symmetrically provided on the bidirectional screw rod, and the stop block extends to the outside of the lower pressure block.

[0014] Furthermore, in order to facilitate the rotation of the bidirectional screw rod, one end of the bidirectional screw rod extends outside the lower pressing block and is fixedly connected to the hand wheel.

[0015] Furthermore, in order to increase the friction between the clamping block and the plate, an anti-slip pad is fixedly connected to the clamping block.

[0016] The beneficial effects of the utility model are:

[0017] 1. By bringing one end of the plate into contact with the pushing block, the reciprocating motor works, and the reciprocating motor drives the bidirectional threaded rod to rotate in the cavity. The rotation of the bidirectional threaded rod causes the two sliders to slide toward each other. The sliding of the slider causes the clamping block to clamp the plate. The feeding motor works, driving the drive shaft to rotate in the side box, and causing the second bevel gear to rotate accordingly. The second bevel gear engages with the first bevel gear, so that the threaded rotating rod rotates in the feeding cavity. The rotation of the threaded rotating rod causes the moving block to move on the frame, and the pushing block moves accordingly. The anti-deviance component fixes the plate on the pushing block, which can effectively prevent the pushing block from moving the plate and causing the plate to deviate, thereby further avoiding affecting the quality of the plate bending.

[0018] 2. The pushing block pushes the plate to move, so that the edge of the plate exceeds the left end of the bending block and reaches the appropriate bending size. The hydraulic cylinder works to drive the lower pressing block to move, so that the block on the lower pressing block contacts the plate to prevent the plate from moving during the bending process. The cylinder works and drives the bending block to move in the bending groove and bends the plate. By turning the handwheel, the distance between the blocks can be adjusted according to the size of the plate, which makes it easier for the blocks to fix plates of different sizes, further improving the practicality of the plate edge bending device.
