Description

Automatic pipe pointing method

Technical Field

The invention relates to the technical field of pointing machines, in particular to an automatic pointing method for a pipe.

Background

With the continuous development of society, the machining industry has been rapidly developed. In the mechanical processing process, the cast rolling production processing is an important component. In the cast-rolling production process, the combined drawing equipment is key equipment in a copper pipe production line, mainly used for drawing pipes, is very important in the production line, directly influences the production running condition of the whole production line, and has higher requirement on the skill of staff. The tube is mainly drawn by the moving core head in the drawing process, which is very beneficial to improving the production efficiency and the yield of a production line, but cannot completely replace the fixed core rod for drawing. The movable core print or the fixed core print needs to be pointed first to be drawn. The tip pressing machine is mainly used for pressing a copper pipe into a head fixing core head, and is convenient to penetrate into a die to clamp and draw. The solid length of the pressing tip is 250mm, the distance from the solid section of the pressing tip to the pit digging position is 110mm, the distance is too short, the core print is easy to crush, the hollow drawing is easy to cause if the distance is too long, and the diameter of the pressing tip section is about 23-25 mm and is approximately cylindrical. The pointing process is all manually operated, manual air blowing is needed firstly, air leakage is serious in the air blowing process, manual pit digging is carried out after air blowing is finished, oil is manually pumped, core heads are manually placed, and an operator manually points according to the required position. The whole operation link is completed manually, particularly manual pit digging is performed, operators use iron bars to dig pits, 200 times of knocking actions are required every day, and labor intensity is high. Place core head in-process and combine completely with the pipe wall in order to guarantee the core head, need operating personnel to use the bar copper to stamp the core head, guarantee the core head and target in place with this, the in-process of pinching is because of operating personnel's difference, the position of digging a pit, the core head position is all gone on by the experience, personnel's technical ability reason in addition, the in-process change of pinching is big, often crush the core head at the in-process of pinching, serious direct crushing, the damage core head is drawing the in-process and is managed the copper pipe inner wall fish tail, directly cause the product to scrap, the yield descends, influence production efficiency.
