Wherein in the initial state, the electromagnet 87 adsorbs the lower limit plate 742 on the grinding shaft 74, at this time, the grinding shaft 74 compresses the first elastic member 76, the highest point of the conical grinding head 743 thereon does not exceed the upper plane of the stamping template 4, when the stamping head 3 moves downwards, the conical grinding head 743 is not propped against, when the electromagnet 87 is released, the grinding shaft 74 slides upwards under the action of the first elastic member 76, the conical grinding head 743 thereon exceeds the upper plane of the stamping template 4, and the diameter of the grinding head connecting shaft 745 is smaller than the diameter of the bottom circle of the conical grinding head 743, so that when the grinding head connecting shaft 745 props against the edge of the stamping hole on the stamping template 4, the bottom of the conical grinding head 743 already crosses the boundary line of the stamping hole, and at this time, the stamping material lifts upwards under the action of the plate lifting device 41, a certain space exists between the stamping template 4, the top of the conical grinding head 743 exceeds the bottom of the stamping material, the beveled edges of the conical grinding heads can thus bear against the edge of the hole punched in the punched material.

The electric push rod 86 is arranged on the bottom frame 9, when the electric push rod is in an extending state, the telescopic rod at the front end is positioned in the rotating stroke of the third combined gear 71, so that when the third combined gear 71 rotates to the position, the telescopic rod is locked at the position, the rotating plate 75 does not rotate any more, when the third combined gear 71 needs to be unlocked, the telescopic rod retracts downwards, the blocking at the front end of the third combined gear 71 disappears, and the rotating plate 75 can continue to rotate under the action of the volute spiral spring 61.

In the initial state, the electromagnet 87 attracts the grinding shaft 74, the slide locking shaft 82 slides to the most intermediate position by the pull rope 84, the slide ring 73 is locked at the starting position, and the electric push rod 86 is in the extended state, and the third combination gear 71 is locked.

The working principle or the using method is as follows:

when the punching head 3 moves downwards, the plate is driven to downwards press and contact the jacking shaft 411, after the plate completely presses and contacts the template 4, the punching head 3 is matched with a punching hole formed in the punching template 4 and continuously slides downwards, the punching hole is formed by punching on the plate, at the moment, the jacking shaft 411 downwards compresses the jacking spring 413 and simultaneously presses and contacts the press and contact switch 414, when punching, the punching head 3 drives the first rack 51 to slide downwards so as to drive the first flat gear 521 to rotate, so that the first bevel gear 522 transmits power to the second bevel gear 531, the power is transmitted to the second belt pulley 541 through a transmission belt so as to drive the spring rotating shaft 54 to rotate, because the spring rotating shaft 54 is arranged on the transition shaft sleeve 64 in a unidirectional rotation manner, the transition shaft sleeve 64 is arranged on the rotating plate 75 in a unidirectional rotation manner, and the rotation is locked by the electric push rod 86 at the moment, therefore, when the punching head moves downwards, the spring rotating shaft 54 is driven to rotate, the spring rotating shaft 54 drives the transition shaft sleeve 64 to rotate, so that the transition shaft sleeve 64 drives the scroll spring 61 to tightly stir, when the punching head 3 moves upwards, the spring rotating shaft 54 is driven to rotate in the opposite direction, at the moment, the rest of the transition shaft sleeve 64 of the spring rotating shaft 54 can rotate relatively, the elastic force of the scroll spring 61 is released and is opposite to the direction of tight stirring, therefore, when the scroll spring releases the elastic force, the transition shaft sleeve 64 and the spring rotating shaft 54 rotate relatively, the rotating plate 75 can be driven to rotate, therefore, when the punching head 3 moves upwards and leaves the punching plate, the jacking shaft 411 slides upwards under the action of the jacking spring 413, so that the plate is jacked upwards to form a certain space with the punching template 4, and at the moment, the jacking shaft 411 is separated from the contact switch 414, so that the micro motor 81 is controlled to loosen the pull rope disc 85, so that the sliding locking shaft 82 slides backwards under the action of the third elastic element 83, thereby canceling the locking of the slide ring 73.

Meanwhile, the electromagnet 87 is powered off, so that the grinding shaft 74 slides upwards under the action of the first elastic piece, the conical grinding head 743 on the grinding shaft is positioned in a space between the plate and the stamping template 4, and the sliding ring 73 drives the grinding shaft 74 to slide outwards along the first long groove 751 under the action of the annular elastic rope 72 because the limit of the sliding ring 73 disappears at the moment, and the conical grinding head 743 on the grinding shaft 74 is abutted against the edge of the hole punched and formed in the stamping material.

Meanwhile, the electric push rod 86 retracts downwards to unlock the third combination gear 71, so that the scroll spring 61 drives the rotating plate 75 to rotate, the third combination gear 71 is driven to rotate around the second flat gear 63, the third flat gear 711 on the third combination gear rotates, the whole third combination gear 71 is driven to rotate, the annular elastic rope 72 is driven to rotate, the sliding ring 73 is finally driven to rotate, the polishing shaft 74 rotates along with the sliding ring 73, and the formed hole edge of the plate is polished in a rotating mode.

At this time, the rotating plate 75 rotates around the second flat gear 63, so that the grinding shaft 74 is driven to make a circular motion around the second flat gear 63, the annular elastic rope 72 can be lengthened and shortened, and power is continuously transmitted in the lengthening and shortening processes, so that when a punched long slotted hole is met, the conical grinding head 743 on the grinding shaft 74 is pressed against the edge of the long slotted hole and slides back and forth on the first long groove 751 along the long slotted hole sliding ring 73, and the conical grinding head 743 is always attached to the edge of the long slotted hole to grind the edge of the slotted hole.

After a certain time of polishing, the electric push rod 86 extends upwards to lock the third combination gear 71 again, the micro motor 81 is started to drive the rope pulling disc 85 to rotate and tighten the pulling rope 84, so that the sliding locking shaft 82 slides towards the center to drive the sliding ring 73 to slide towards the center together, thereby compressing the third elastic element 83, after the sliding ring 73 is pulled to the center position, the micro motor 81 is braked and locked to keep the state, at this time, the electromagnet 87 is started to adsorb the polishing shaft 74, so that the polishing shaft 74 slides downwards, and all the components return to the initial state.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
