Technical Field
The invention relates to the technical field of bending machines, in particular to a bending machine protection device.
Background
The bending machine is a machine capable of bending thin plates, and mainly structurally comprises a support, a workbench and a clamping plate, wherein the workbench is arranged on the support and comprises a base and a pressing plate, the base is connected with the clamping plate through a hinge and comprises a seat shell, a coil and a cover plate, the coil is arranged in a recess of the seat shell, and the cover plate covers the top of the recess. When the clamping device is used, the coil is electrified by the lead, and the attraction is generated on the pressing plate after the coil is electrified, so that the thin plate between the pressing plate and the base is clamped. The electromagnetic force clamping is adopted, so that the pressing plate can be made into various workpiece requirements, and the workpiece with the side wall can be processed, and the operation is very simple and convenient. The hydraulic bending machine comprises a support, a workbench and a clamping plate, the workbench is arranged on the support and comprises a base and a pressing plate, the base is connected with the clamping plate through a hinge, the base comprises a seat shell, a coil and a cover plate, the coil is arranged in a recess of the seat shell, and the cover plate covers the top of the recess. When the clamping device is used, the coil is electrified by the lead, and the attraction is generated on the pressing plate after the coil is electrified, so that the thin plate between the pressing plate and the base is clamped. Due to the adoption of electromagnetic force clamping, the pressing plate can be made into various workpiece requirements, and the workpiece with the side wall can be processed. The bending machine can meet the requirements of various workpieces by replacing a bending machine die. Present bender is carrying out panel bending man-hour, the panel that is located the bender outside can reverse, operating personnel is hindered by panel mistake easily when being close to the bender, cause the unnecessary damage, if operating personnel uses and is not put the hand between lower mould and clamp plate, can cause more serious incident when bending, consequently need bender protector to protect operating personnel, but the structural design of present bender protector on the market at present is reasonable inadequately, it is lower to detect the precision, still probably cause the mistake to operating personnel and hinder, unsuitable using widely.
