Detailed Description

The present utility model is described in detail below by way of examples only for further explanation of the present utility model and is not to be construed as limiting the scope of the present utility model.

As shown in fig. 1 and 2, this embodiment discloses a cold header annular scrap removing device, including a sliding table 1 and a die holder 2 capable of moving back and forth, and further including a blanking ejector rod 3 driven by the sliding table 1 and a die 4 mounted on the die holder 2, wherein the blanking ejector rod 3 and the die 4 travel a processing station on the cold header, the tubular body material 10 moves into the die 4 after being formed by the first several stations, the end of the blanking ejector rod 3 is provided with a conical blanking end 31, the opening end of the die 4 is provided with a blanking port 41 matched with the blanking end 31, as shown in fig. 3, the annular scrap 101 of the tubular body material 10 in the die 4 is placed at the blanking port 41, when the blanking end 31 of the blanking ejector rod 3 contacts with the blanking port 41, an extrusion punching action is formed, so that the annular scrap 101 at the position of the blanking port 41 can be punched, the lower annular scrap 101 can be on the blanking ejector rod 3, a sliding seat 5 capable of guiding and sliding before and after limiting is arranged below the front end of the die holder 2, the die 5 is provided with a reset spring 6, the blanking slider 7 is arranged on the blanking ejector rod 3 through a reset spring 6, and the blanking punch 71 can be punched 71 after the blanking ejector rod 3 is arranged on the blanking ejector rod 3, and the blanking blade 71 can be punched 71 after the blanking ejector rod 3 is punched.

The slide 5 slidable mounting is on guide arm 8, and the both ends of guide arm 8 are fixed respectively on mount pad 9, can carry out spacingly to the slip of slide between two mount pads 9, disposes reset spring 6 between one mount pad 9 and the slide 5, and after the slip table 1 return, the slide 5 is under reset spring 6's effect butt on the mount pad 9 of another principle mould seat 2, accomplishes the reset, and the ejector pin 3 that dashes this moment also can return along with slip table 1, and the return stroke of ejector pin 3 that dashes is greater than on the slide 5 scrapes flitch 7 to punch pin 3 withdraws from the perforation 71 on the flitch 7, makes the hanging plate get rid of the annular waste 101 of ejector pin 3 that dashes.

By adopting the technical scheme, after the tubular body material 10 moves into the female die 4, the annular waste 101 at the end of the tubular body material 10 is positioned at the position of the blanking port 41 of the female die 4, the punching end 31 at the end of the punching ejector rod 3 driven by the sliding table 1 and the blanking port 41 punch against the tubular body material 10 at the position of the blanking port 41 to perform punching action, at the moment, the annular waste can be hung on the punching ejector rod 3, and the annular waste exits from the perforation 71 when the punching ejector rod 3 returns, so that the annular waste edge of the tubular body material 10 is accurately removed and a finished product is formed, and the structure is reasonable and reliable.

The structure is arranged at one station on the concave-convex die of the cold header, and the purpose of removing the annular waste 101 is achieved in the cold forging process of the tubular body material 10, so that the port of the tubular body material 10 is smoother, and the port meets the processing requirement of a finished product.
