Description

Technical Field

[0001] This utility model relates to the field of workpiece processing equipment technology, and in particular to a bending device for processing plate-shaped workpieces. Background Technology

[0002] In the application of workpieces, it is often necessary to process plate-shaped workpieces by bending them to suit different working requirements.

[0003] A search revealed a publication (announcement) number: CN218925786U, which discloses a high-precision bending and forming device for workpieces, relating to the field of excavator mudguard processing equipment. The device includes a hydraulic upper die and a hydraulic lower die. The hydraulic upper die includes a rolling portion, with a first bending portion and a third bending portion arranged along the tangent direction of the rolling portion. The included angle between the rolling portion and the third bending portion is an obtuse angle. A second bending portion is provided at one end of the first bending portion, with an obtuse angle between them. A first vertical portion is provided at one end of the second bending portion, and a second vertical portion is provided at one end of the third bending portion. The shape of the hydraulic lower die is adapted to the hydraulic upper die. This device combines the rolling and bending processes of the mudguard into one, achieving high-precision bending and forming of the mudguard through the cooperation of the hydraulic upper die and the hydraulic lower die, significantly improving work efficiency and product consistency.

[0004] While the above solution significantly improves work efficiency and product consistency, the extrusion head is prone to damage during the extrusion process and needs to be replaced in a timely manner. It is also necessary to adjust the distance between the plate-shaped workpiece and the bottom to ensure stable support force, and to consider the length of the plate-shaped workpiece to optimize the clamping effect on plate-shaped workpieces of different lengths. Utility Model Content

[0005] The main objective of this invention is to provide a bending device for processing plate-shaped workpieces. By setting up a bending unit, it solves the problems of the extrusion head being easily damaged during the extrusion process and needing to be replaced in a timely manner, as well as the need to adjust the distance between the plate-shaped workpiece and the bottom end to ensure stable support force. By setting up a fixing unit, it solves the problem of also considering the length of the plate-shaped workpiece and optimizing the clamping effect for plate-shaped workpieces of different lengths.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bending device for processing plate-shaped workpieces includes a fixed base, a bending unit disposed inside the fixed base, and a fixing unit disposed on the side of the bending unit.

[0008] The bending unit includes an extrusion assembly disposed at the top of the interior of the fixed base, and a lifting assembly disposed at the bottom of the interior of the fixed base;

[0009] The fixed unit comprises a pushing assembly arranged on both sides of the fixed base and a clamping assembly arranged at one end of the pushing assembly.

[0010] Preferably, the extrusion assembly in the bending unit comprises a first cylinder arranged at the top end of the fixed base, a first telescopic column fixedly connected to the bottom end of the first cylinder, a circular groove opened at the bottom end of the first telescopic column, a plurality of grooves communicated and arranged on both sides of the circular groove, a first elastic column arranged in the grooves, a first spring arranged on the surface of the first elastic column, and a clamping block fixedly connected to one end of the first elastic column.

[0011] Preferably, the extrusion assembly in the bending unit further comprises an extension column arranged in the circular groove and matched with the plurality of clamping blocks, and an arc-shaped seat fixedly connected to the bottom end of the extension column.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] Firstly, in the utility model, when the arc-shaped seat needs to be replaced, the arc-shaped seat needs to be twisted first so that the clamping block and the extension column are not tightly matched, and then the arc-shaped seat can be conveniently replaced by pulling it down, and the height of the support plate needs to be adjusted according to the length of the plate-shaped workpiece, the plurality of plug-in columns are removed, and then the plurality of second cylinders are started to drive the second telescopic column to rise, thereby driving the support plate to rise, and then the plurality of plug-in columns are inserted into the corresponding limiting holes, so that stable supporting force is ensured in the subsequent bending process.

[0018] II. In this utility model, by setting the fixing unit, the plate-shaped workpiece is placed between two L-shaped plates. Then, under the action of the second elastic column and the second spring, the limiting plate is driven to descend, which initially restricts the position of the plate-shaped workpiece. The locking bolt is also rotated to drive the movable block to descend, which further squeezes the limiting block, thereby stably clamping the plate-shaped workpiece. At the same time, two third cylinders can be activated to drive the third telescopic column to extend or retract, which changes the distance between the two L-shaped plates, thereby adapting to plate-shaped workpieces of different lengths.
