In one embodiment of the present invention, the connecting rod 51 is sleeved with a corrugated air bag 52; one end of the corrugated air bag 52 is fixedly connected with the machine body 1, and the other end of the corrugated air bag is fixedly connected with the cleaning plate 5; the corrugated air bag 52 is communicated with the groove 13; one surface of the cleaning plate 5, which is far away from the connecting rod 51, is provided with an air hole 53 communicated with the corrugated air bag 52; an air passage 15 communicated with the outside is formed at the bottom of the groove 13; the air hole 53 and the air passage 15 are both internally provided with a one-way valve 16; when the punching die works, when a worker pushes the punching part to extrude the cleaning plate 5 to move towards the direction of the bottom of the groove 13, the cleaning plate 5 can extrude the corrugated air bag 52, so that gas in the corrugated air bag 52 is extruded and is sprayed out from the air hole 53, and the gas is sprayed to the punching part, so that scrap iron adhered to the upper end surface of the punching part can be separated from the upper end surface of the punching part under the blowing of the gas, and the condition that the scrap iron is located at the position of the punching part punched by the punch 11 and causes damage to the lower end of the punch 11 due to local region stress concentration in the punching process of the punch 11 is avoided, the service life of the punch 11 is further prolonged, and the practicability of the punching die is effectively improved; when the cleaning plate 5 slides along the upper end of the punching die holder 12 under the pushing of the restoring force of the spring, the cleaning plate 5 pulls the corrugated air bag 52 to extend, and external air enters the corrugated air bag 52 through the air passage 15 under the action of the check valve 16, so that burrs and iron chips at the upper end of the punching die holder 12 are prevented from accumulating on the pushing surface of the cleaning plate 5 and entering the air hole 53, the air hole 53 is prevented from being blocked, the normal use of the air hole 53 is further ensured, and the practical application effect of the invention is improved.
As an embodiment of the present invention, the cleaning plate 5 is disposed obliquely; the included angle between the cleaning plate 5 and the upper end face of the punching die holder 12 is 120-160 degrees; when the cleaning plate 5 is in operation, the cleaning plate 5 is obliquely arranged, so that in the process that the cleaning plate 5 slides along the upper end of the punching die holder 12, burrs and scrap iron on the upper end of the punching die holder 12 can be scraped obliquely by the cleaning plate 5, and the scrap iron on the scraping surface of the cleaning plate 5 continuously moves upwards along the inclined surface of the cleaning plate 5 along with the scraping of the cleaning plate 5, so that the scrap iron accumulation amount of the contact position of the cleaning plate 5 and the upper end surface of the punching die holder 12 is reduced, the blocking force of the scrap iron on the cleaning plate 5 is reduced, the scraping effect of the cleaning plate 5 on the burrs and the scrap iron on the upper end of the punching die holder 12 is further enhanced, and the practical application effect of the cleaning plate is further improved.
The specific working process is as follows:
a worker places a stamping part of the electromechanical shell at the upper end of the punching die holder 12, controls the punch 11 to move downwards through the controller, and enables the punch 11 to punch a hole on the stamping part, after the punching is completed, the controller controls the punch 11 to reset and controls the polishing mechanism below the punching die holder 12 to ascend, so that the polishing mechanism penetrates through a punching hole of the punching die holder 12 and enters the punched hole of the stamping part, and the polishing mechanism polishes the edge of the punched section of the stamping part, so that not only can burrs on the edge of the section of the stamping part fall off, but also the edge of the section of the punched hole can generate a chamfer under the polishing of the polishing roller 2; after polishing is finished, the controller controls the polishing roller 2 to reset, when the polishing roller 2 is completely reset, a worker takes off a stamping part, burrs and scrap iron falling from the surface of the stamping part remain on the punching die holder 12, the worker controls the cleaning mechanism to clean the burrs and scrap iron on the punching die holder 12 through the controller, the situation that the stamping part is placed unevenly due to the burrs and the scrap iron on the punching die holder 12 is prevented, and the stamping part is prevented from being punched obliquely; the punch 11 is controlled by the controller to move downwards, so that the punch 11 punches the stamping part, at the moment, the limiting rod 3 positioned at the lower end of the punch 11 synchronously moves downwards along with the punch 11 until the T-shaped rod 32 at the lower end of the limiting rod 3 is contacted with the stamping part on the stamping die holder 12, so that the T-shaped rod 32 tightly supports the stamping part on the stamping die holder 12, and as the punch 11 continuously moves downwards, the T-shaped rod 32 extrudes the spring to enter the limiting groove 31 under the blocking of the stamping part until the punch 11 finishes the stamping of the stamping part; at the moment, the controller controls the punch 11 to ascend, and simultaneously controls the driving module to operate, so that the driving module drives the grinding roller 2 at the upper end to rotate and ascend, the chamfering module at the upper end of the grinding roller 2 extends into the punching hole, and the rotating grinding roller 2 grinds burrs in the punching hole; the T-shaped rod 32 at the upper end of the stamping part tightly supports the stamping part on the punching die holder 12 under the action of the spring restoring force, so that the stamping part cannot push the stamping part to ascend under the action of the friction resistance of the grinding roller 2 in the process that the grinding roller 2 rotates and ascends in the punching hole of the stamping part, the grinding roller 2 can stably grind the punching hole of the stamping part, and the actual application effect of the invention is effectively improved; when the chamfering module at the upper end of the grinding roller 2 extends out of the punching hole, the controller controls the chamfering module to extend out of the grinding groove 24, so that the chamfering module and the edge of the punching section of the punching part, which is far away from the punching die holder 12, are ground to generate a chamfer, and burrs at the edge of the section of the punching part also fall off under the grinding of the chamfering module.
