Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bending machine with a shielding cover. 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 and consists of a base and a pressure plate. The working principle of the bending machine is to generate pressure through the hydraulic system, so that the slider drives the upper die downward and closes the lower die to achieve bending of metal plates. The hydraulic system consists of a hydraulic pump, an oil tank, an oil pipe, a hydraulic cylinder, etc. The hydraulic pump generates high-pressure oil and transports it to the hydraulic cylinder to push the slider up and down.

[0003] During the bending process of metal sheets by a press brake, tiny metal particles may be generated on its surface due to friction, extrusion and other factors. These metal particles are suspended in the air to form metal dust. Especially when dealing with metals such as titanium alloys, due to their high hardness, metal dust is more likely to be generated. These metal dusts not only have adverse effects on the health of the operator, but may also cause pollution to the environment. Therefore, a press brake with a shielding cover is now proposed. Summary of the invention

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that metal dust generated during the bending process of the metal plate by the bending machine not only has an adverse effect on the health of the operator but also may pollute the environment, and a bending machine with a shielding cover is proposed.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When this equipment is in use, the hydraulic cylinder controls the bending plate to move downward to bend the plate through the lifting plate. The lifting plate will drive the shielding cover to move downward and insert it into the moving slot. The fan then sucks the air containing metal dust inside the shielding cover through the dust suction pipe through the air inlet pipe, and then discharges it into the interior of the collection box through the dust suction pipe and filters the metal dust through multiple metal filters, and then discharges it through the air inlet pipe and exhaust pipe.
