[0002] Cold drawing is an important production method for steel pipes. Cold drawing equipment is mainly cold drawing machine. Before cold drawing, seamless steel pipe is a blank steel pipe. One end of the blank steel pipe to be cold drawn is hammered flat and pointed so that the blank steel pipe can extend out of the outer die hole of the cold drawing machine, so that the cold drawing trolley can clamp the hammer head for cold drawing. This process is widely used to this day. There are two main ways to blank cold drawn steel pipes. One is manual blanking, which is done manually by at least two workers; the other is a mechanized automatic blanking device. This blanking device auxiliary equipment makes a lot of noise when blanking; To this end, the utility model patent with the publication number CN217665459U discloses a device for cold drawing and blanking of stainless steel pipes, including a bottom frame, both ends of which are provided with openings, and a collection bin is arranged inside the bottom frame; support frames are vertically fixed on both sides of the upper end of the bottom frame, and the first blanking plate and the second blanking plate are rotatably installed on the inner walls of the support frames on both sides, and the first blanking plate and the second blanking plate are both tilted downward, and the first blanking plate and the second blanking plate are cross-arranged, and the backs of the first blanking plate and the second blanking plate are both provided with a first spring.
