As shown in fig. 13, when the connecting rod 4251 moves upward, the second inclined surface 4251b abuts against the second abutting portion 4252c, and pushes the movable block 4252 to move away from the punch seat 423. The structure is ingenious, and the function that the movable block 4252 moves towards the direction far away from or close to the punching seat 423 when the connecting rod 4251 moves up and down is realized.
As shown in fig. 10, 11 and 14, in particular, the second driving assembly 43 includes a second fixed plate 431, a second cylinder 432, a second push plate 433 and a second guide rod 434. The second fixing plate 431 is fixed on the frame 10, and the cylinder body of the second cylinder 432 is fixedly connected to the second fixing plate 431; one end of the second push plate 433 is fixedly connected with a piston rod of the second cylinder 432, and the other end is fixedly connected with the supporting seat 421; one end of the second guide rod 434 is fixedly connected to the second fixing plate 431, and the other end thereof passes through the second push plate 433. The piston rod of the second cylinder 432 extends and retracts, so that the second push plate 433 reciprocates along the second guide rod 434, thereby driving the support seat 421 to reciprocate.
As shown in fig. 10, 11 and 14, preferably, the punching device 42 further comprises a waste removing assembly 427 for removing waste of the first and second grooves 4261 and 4262 left on the second positioning rod 426 after the pipe is punched, wherein the waste removing assembly 427 comprises a scraper plate 4271 and a push rod 4272; a through hole is formed in the scraping plate 4271 and matched with the second positioning rod 426, the scraping plate 4271 is movably arranged in the punching cavity 4231, and the second positioning rod 426 penetrates through the through hole; one end of the push rod 4272 passes through the punch seat 423 to be fixedly connected to the scraping plate 4271, and the other end of the push rod 4272 is elastically connected to the second fixing plate 431. Before punching, when the supporting seat 421 moves towards the direction close to the pipe, the scraping plate 4271 slides inwards relative to the punching cavity 4231 and penetrates into the punching cavity 4231, and after punching is completed, when the supporting seat 421 moves towards the direction away from the pipe, the scraping plate 4271 slides outwards relative to the punching cavity 4231 and scrapes waste materials of the first groove 4261 and the second groove 4262 on the second positioning rod 426. And since the scraping plate 4271 is connected to one end of the push rod 4272, the other end of the push rod 4272 is elastically connected to the second fixing plate 431. When the waste materials are hard and the scraping plate pieces 4271 are blocked from moving, the waste materials can also move elastically and are prevented from being damaged.
Specifically, the defective product removing mechanism 50 includes a third cylinder and a placing plate (not shown), and when an unqualified pipe is sent to the defective product removing station, the unqualified pipe is placed on the placing plate, the third cylinder drives the placing plate to drop the unqualified pipe, and when a qualified pipe is sent to the defective product removing station, the unqualified pipe is placed on the placing plate, and the third cylinder does not drive the placing plate to allow the qualified pipe to be taken away by the blanking mechanism 60. Specifically, the blanking mechanism 60 is a conveyor belt.
According to the continuous punching equipment for the pipe, the parts are arranged, so that the pipe can be continuously punched, the punching is rapid and convenient, and three holes can be punched in one step for the pipe.
