Description

Technical Field

[0001] The utility model relates to the technical field of protective structures, in particular to a protective structure of a bending machine for steel plate processing. Background Art

[0002] A bending machine is a machine that can bend thin plates. It is an important equipment for bending and forming workpieces in the sheet metal industry. Its function is to press steel plates into parts of various shapes according to process requirements.

[0003] The bending machines used for folding on the market are generally used to place one end of the steel to be bent on the lower mold of the bending machine manually or by machine. The upper mold moves downward to apply pressure to the steel to cause it to deform. There will be staff watching in the middle to prevent deviations in the bending position. However, sometimes the metal fatigue increases during the process of stress deformation and cracks, causing the broken fragments to burst out from both sides of the bending machine and injure the staff or equipment in the working environment, resulting in losses of production materials and production personnel. Therefore, a protective structure for the bending machine used for steel plate processing is needed. Utility Model Content

[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide a protective structure for a bending machine for steel plate processing, which can solve the problem that when the existing bending machine is working, the staff usually need to hold the steel plate by hand to position the steel plate, and also need to hold the steel plate by hand to bend it. Since the steel plate will generate certain stress after deformation, the operator is in a mechanical working state for a long time, which is prone to cause double arms injuries and safety accidents.

[0005] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a protective structure for a bending machine for steel plate processing, comprising a bending machine body and two mounting plates;

[0006] A protective device is provided on the two mounting plates and includes two first fixing plates, the first fixing plates being fixedly connected to the two mounting plates respectively;

[0007] The opposing surfaces of the two first fixing plates are fixedly sleeved with bearings, the inner walls of the two bearings are fixedly connected with connecting shafts, and the opposing surfaces of the two connecting shafts are fixedly connected with second fixing plates;

[0008] The opposite surfaces of the two second fixing plates are fixedly connected with connecting rods, the opposite surfaces of the two connecting rods are fixedly connected with concave fixing plates, and the opposite surfaces of the two concave fixing plates are fixedly connected with two connecting plates.

[0009] Preferably, the opposite surfaces of the two upper and lower corresponding connecting plates are fixedly connected with rectangular fixing plates, and the opposite surfaces of the two rectangular fixing plates are provided with sliding grooves, and the two sliding grooves respectively penetrate the outer surfaces of the corresponding rectangular fixing plates.

[0010] Preferably, the two rectangular fixing plates are fixedly connected to the opposite sides thereof with mounting base plates, and rectangular blocks are fixedly mounted on the upper surfaces of the two mounting base plates.

[0011] Preferably, the opposing surfaces of the two rectangular blocks are fixedly connected with sliders, the opposing surfaces of the two sliders slide through the inner walls of the corresponding sliding grooves respectively, and the opposing surfaces of the two sliders are fixedly connected with first fixing rods.

[0012] Preferably, the opposite surfaces of the two rectangular fixing plates are fixedly connected with a second fixing rod, the opposite surfaces of the second fixing rod and the first fixing rod are provided with a steel plate, the lower surface of the second fixing rod is provided with a placement plate, and the upper surface of the placement plate is provided with a rectangular groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The protective structure of the bending machine for steel plate processing starts two servo cylinders. The telescopic ends of the two servo cylinders drive the two rectangular blocks and the two sliders to move downward. The two sliders drive the first fixed rod to move downward to fix the rear end of the steel plate to prevent the steel plate from generating certain stress after deformation and even causing collapse and flying. This improves the practicality of the protective structure of the bending machine for steel plate processing.

[0016] (2) When the steel plate is subjected to pressure, the right end of the steel plate will tilt up under the pressure, and the right end of the steel plate will lift the first fixed rod to tilt up as a whole, thereby adapting to the movement of the steel plate during bending, further preventing the steel plate from generating certain stress after deformation, and further improving the practicality of the protective structure of the steel plate bending machine.
