The invention discloses an efficient punching device which comprises a frame. A motor is fixedly connected to the inner top wall of the frame, a roller is fixedly connected to the output end of the motor, a workpiece is placed below a drill bit, the motor is started by turning on an external power supply to drive the roller to rotate, four extruding rods can perform vertical reciprocating motionsunder the effect of a sliding rod, a connecting plate is downward extruded four times once the roller rotates for one circle, and accordingly the punching efficiency is improved. The workpiece to be punched is placed below the drill bit, a second spring is compressed when the connecting plate moves down, a twist rod and a sliding block move down, and when universal wheels on a baffle abut againstthe upper end face of a supporting plate, the lower end of the drill bit is in contact with the workpiece, a first insertion rod continues to move down, the twist rod moved down on longer, the first spring is compressed, the sliding block moves down to make the twist rod rotate and thus make the drill bit rotate, and workpiece punching is efficiently achieved.

The invention discloses a punching device for raw bamboo, which comprises a first connecting rod, a second connecting rod, a third connecting rod, a first clamp, a second clamp, a third clamp, a punching machine and a first fixing plate; The first clamp, the second clamp and the third clamp all include a connecting piece, a fourth connecting rod, a fifth connecting rod, a second fixing plate and a limiting plate. This device can effectively prevent the drill bit from slipping, and the drilling The location is more accurate.

The invention discloses a mold, a device and a method for punching a chip component ceramic diaphragm. The punching mold comprises an upper mold, a lower mold and a fixing and positioning device, wherein an upper mold hole and a lower mold hole are correspondingly formed on the upper and lower molds. The punching device comprises a high-pressure water injector and the punching mold, wherein the high-pressure water injector is arranged directly opposite to the upper mold; and when the punching device is used, the ceramic diaphragm is fixed on the positioning device and positioned between the upper mold and the lower mold, and the water injected from the high-pressure water injector breaks through the ceramic diaphragm. The punching method comprises: 1) placing the ceramic diaphragm between the upper mold and the lower mold, 2) fixing and positioning the ceramic diaphragm between the aligned upper mold hole and lower mold hole by using the fixing and positioning device; and 3) allowing the high-pressure water injector to inject water to break through the ceramic diaphragm. The mold, the device and the method have the advantages that: the equipment investment is low; the maintenance cost is low; the device is simply operated; the production cost is low; and the mold, the device and the method can be widely applied to punching of electronic component ceramic materials.
