Abstract
The utility model relates to the technical field of mechanical devices, in particular to a large-aperture punching device which comprises a motor and a drill bit. The drill bit is arranged on the motor and provided with a support, a baffle is arranged under the support, a disc is arranged on the support, punching cutters are evenly arranged on the disc, a through hole is formed in the center of the disc, the disc is fixedly connected with the support through pin shafts, the number of the punching cutters is three, and the bottom end of the drill bit is lower than the bottom ends of the punching cutters in position. When the large-aperture punching device is used for machining plate materials, large round holes can be machined, production requirements are met, and the large-aperture punching device is simple in structure, convenient to operate, and good in use effect.
Description
Technical field
The utility model relates to mechanical device technical field, especially a kind of large aperture perforating device.
Background technology
When some sheet materials are punched, need to use puncher, but the punching diameter of current puncher depends on the size of bit diameter, can not meet the requirement of some demand large aperture punchings.
Utility model content
The deficiency that can not play macropore requirement in order to overcome existing perforating device punching, the utility model provides a kind of large aperture perforating device.
The utility model solves the technical scheme that its technical problem adopts: a kind of large aperture perforating device, comprise motor and drill bit, described drill bit is arranged on motor, described drill bit is provided with support, the below of described support is provided with baffle plate, described support is provided with disk, is evenly placed with perforating knife on described disk, and the center of described disk is provided with through hole.
According to another embodiment of the present utility model, further comprise, between described disk and support, adopt bearing pin to be fixedly connected with.
According to another embodiment of the present utility model, further comprise, the number of described perforating knife is just 3.
According to another embodiment of the present utility model, further comprise, the bottom position of described drill bit is lower than the position of perforating knife bottom.
The beneficial effects of the utility model are, this large aperture perforating device, in to sheet material processing, can process larger circular hole, meets the demand of producing, and apparatus structure is simple simultaneously, simple operation, and result of use is good.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the upward view of the utility model disk.
In figure 1, motor, 2, drill bit, 3, support, 4, disk, 5, perforating knife, 6, baffle plate, 7, bearing pin, 8, through hole.
The specific embodiment
If Fig. 1 is structural representation of the present utility model, a kind of large aperture perforating device, comprise motor 1 and drill bit 2, described drill bit 2 is arranged on motor 1, described drill bit 2 is provided with support 3, and the below of described support 3 is provided with baffle plate 6, and described support 3 is provided with disk 4, on described disk 4, be evenly placed with perforating knife 5, the center of described disk 4 is provided with through hole 8.
According to another embodiment of the present utility model, further comprise, between described disk 4 and support 3, adopt bearing pin 7 to be fixedly connected with.
According to another embodiment of the present utility model, further comprise, the number of described perforating knife 5 is just 3.
