Technical Field
[0001] The present application relates to the technical field of bending machines, and specifically to a fully automatic sheet metal bending machine. Background Art
[0002] Sheet metal is a manufacturing process used to process thin sheet metal materials, usually including steel, aluminum, copper, zinc, nickel, titanium and other materials. The process uses a variety of technologies such as molds, shearing, stamping, bending, welding, and painting to cut, bend, form, and connect thin sheet metal materials into various parts, components, and products.
[0003] During the use of common bending machines, most of them can only process a fixed bending angle for cold-rolled steel plates. When cold-rolled steel plates with different angles need to be processed, workers are required to disassemble the upper and lower molds of the cold-rolled steel plates and replace them with another set of bending molds. The operation is relatively cumbersome and affects production efficiency. Utility Model Content

When cold-rolled steel plates at different angles need to be processed, workers are required to disassemble the upper and lower molds of the cold-rolled steel plates and replace them with another set of bending molds. The operation is cumbersome and affects production efficiency.
[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a fully automatic sheet metal bending machine, comprising a base plate, a top plate is provided above the base plate, a plurality of lower dies arranged at equal distances are provided on the upper surface of the base plate, and a plurality of upper dies are provided below the top plate.
[0006] A group of plug rods are fixedly connected to the upper surface of each upper mold, and each group of the plug rods is plugged into the top plate. A hydraulic cylinder body is arranged above the top plate.
[0007] Through the above scheme, the threaded rod is set to achieve the purpose of driving the hydraulic cylinder body to move horizontally. When it is necessary to process cold-rolled steel plates at different angles, it is only necessary to drive the hydraulic cylinder body to the upper part of the upper die at the corresponding angle, and drive the contact plate to press the pressure plate down to close the upper die and the lower die, thereby achieving the effect of fast processing of cold-rolled steel plates at different angles without changing the mold, effectively improving the overall production efficiency, with lower overall cost and higher flexibility.

[0010] Furthermore, two conveying plates are fixedly connected to the upper surface of the top plate, a threaded rod is rotatably connected between the two conveying plates, and a moving block is fixedly connected to the upper surface of the hydraulic cylinder body, and the moving block is threadedly connected to the threaded rod.
[0011] Through the above solution, the purpose of driving the hydraulic cylinder body to move can be achieved through the threaded connection between the moving block and the threaded rod.
[0012] Furthermore, two guide rods are fixedly connected between the two conveying plates, and the outer surfaces of the two guide rods are sleeved with limit blocks, and the two limit blocks are fixedly connected to the hydraulic cylinder body.
[0013] Through the above scheme, the guide rod is provided to limit the movement of the hydraulic cylinder body, thereby ensuring the stability of its movement.
[0014] Furthermore, a pressure plate is fixedly connected to the top end of each group of the insertion rods.
[0015] Through the above scheme and the setting of the pressing plate, the purpose of moving four insertion rods simultaneously can be achieved, and the upper mold can be ensured to move stably in a straight line.
[0016] Furthermore, four springs are fixedly connected between each of the pressure plates and the top plate, and each of the springs is sleeved with an adjacent insertion rod.
[0017] Through the above scheme and the setting of the spring, the purpose of resetting the upper mold can be achieved.
[0018] Furthermore, the right end of the threaded rod is fixedly connected to the output end of the external motor.
[0019] Through the above solution, by setting up an external motor, it is possible to provide power for the rotation of the threaded rod.
[0020] Furthermore, a contact plate is fixedly connected to the output end of the hydraulic cylinder body.
[0021] Through the above solution and the setting of the contact plate, the force-bearing area of the pressure plate can be increased, so that it can move downward stably.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] This fully automatic sheet metal bending machine can achieve the purpose of driving the hydraulic cylinder body to move horizontally through the arranged threaded rod. When it is necessary to process cold-rolled steel plates of different angles, it is only necessary to drive the hydraulic cylinder body to the upper part of the upper die of the corresponding angle, and drive the contact plate to press the pressing plate downward to close the upper die and the lower die, thereby achieving the effect of fast processing of cold-rolled steel plates of different angles without changing the die, effectively improving the overall production efficiency, lowering the overall cost and increasing flexibility.

Through the setting of the pressing plate 13, the purpose of moving the four insertion rods 5 at the same time can be achieved, which can ensure that the upper mold 4 can move stably in a straight line.

[0036] A fully automatic sheet metal bending machine in the present embodiment can achieve the purpose of driving the hydraulic cylinder body 6 to move horizontally through the set threaded rod 9.
