Description
Technical Field
[0001] The utility model relates to the technical field of turnover equipment, in particular to a turnover device for a bending machine. Background Art
[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base consists of a base shell, a coil and a cover plate. The coil is placed in the recess of the base shell, and the top of the recess is covered with a cover plate. When in use, the coil is energized by a wire, and after power is turned on, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. Due to the use of electromagnetic clamping, the pressure plate can be made into a variety of workpiece requirements, and can process workpieces with side walls. It is also very simple to operate. Generally, in fully automatic bending machines, the plate needs to be flipped.
[0003] The turning device for a press brake is an auxiliary device that is mainly used to lift and turn large or heavy metal plates so that they can be placed on the workbench of the press brake for processing. This device greatly improves work efficiency, reduces the labor intensity of manual operation, and increases work safety.
[0004] Traditional flipping devices can only flip plates of a certain size and specification, and have poor applicability. They only rely on squeezing the side walls of the plates or only rely on pressing and fixing the upper and lower surfaces of the plates during the flipping operation. Due to the lack of firm limitation and fixation of the plates, they are prone to slipping during the flipping process. Utility Model Content

[0030] First of all, it should be made clear that the flipping device involved in the present invention is mainly used for flipping the plate during the bending process. The present invention takes the flipping of the aluminum plate during the bending process as an example to explain its method of use in detail. When the aluminum plate needs to be bent, first start the output rod of the two-way telescopic push rod 124 to extend it to match the length direction of the aluminum plate (adjust to the distance between the two clamps 141 greater than the 20mm displacement of the aluminum plate length), then place the aluminum plate on the support plate 142, push the aluminum plate inward to the appropriate position, and then start the output rod of the two-way telescopic push rod 124 to retract it to push the two clamps 141 inward to clamp the left and right side walls of the aluminum plate, and then start the output rod of the hydraulic cylinder 144 to extend it to push the pressure plate 145 downward to tighten the upper surface of the aluminum plate. The surface is pressed and fixed, and then the operator starts the output shaft of the motor 132 to rotate it to a suitable angle (for example, rotate it 180 degrees), so that the plate can be turned over firmly, stably and efficiently. The utility model can achieve firm, stable and efficient clamping, fixation and turning of the side walls and upper and lower surfaces of plates of various specifications through the spacing adjustment component 120 in conjunction with the flipping component 130 and the clamping component 140, which solves the problem that the traditional flipping device can only flip plates of a certain specific size and has poor applicability. It only relies on squeezing the side walls of the plate or only relies on pressing and fixing the upper and lower surfaces of the plate during the flipping operation. It is easy to have the problem of slipping during the flipping process due to the lack of firm limitation and fixation of the plate.
[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense.
