Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to an online double-servo punching machine. Background Art

[0002] When processing plates, a punching machine is needed to punch holes in them. Although traditional plate punching machines can perform punching operations on plates, they cannot fix the plates during the punching process and cannot blow away the waste chips generated by punching from the plates, which will cause the waste chips to fall into the holes and affect the punching effect. Many working environments have small spaces, insufficient light, and cannot introduce large lighting equipment, which has a great impact on the workers' drilling.

[0003] The prior art discloses a punching machine for sheet metal, comprising a lighting panel, a connecting plate, an air blower, a handle, a support plate, a base, a fluorescent strip, a motor, an electric cylinder, an air vent, a drill bit, and a connecting shaft. The left end of the base is fixed with a support plate, the upper end of the support plate is fixed with a connecting plate, the upper end of the connecting plate is fixed with a motor, the lower end of the motor is fixed with a connecting shaft, the lower end of the connecting shaft passes through the connecting plate and extends below the connecting plate, the lower end of the connecting shaft is fixed with a drill bit, the right end of the support plate is fixed with an air pump, the bottom end of the electric cylinder is fixed with an electric cylinder, the upper end of the electric cylinder is fixed with a lifting rod, the upper end of the lifting rod passes through the base and extends above the base, the upper end of the lifting rod is fixed with a placement plate, the right end of the placement plate is fixed with an air pump, the right end of the air pump is fixed with an air outlet pipe, and the drill bit is located above the placement plate. This utility model facilitates fixing sheet metal, has good punching effect, and is highly efficient.

[0004] However, when the above equipment is used in actual processing, sometimes the plate needs to be punched on both sides. The above equipment uses a single processing position for punching, so when punching holes at both ends of the plate, it is necessary to punch one side, remove the workpiece, turn the direction and clamp it, and then punch the other end again, which is inefficient. Utility Model Content

[0011] Wherein, the auxiliary mechanism further includes an isolation cover, which is detachably connected to the machine and is located at the inlet side of the return pipe.
