Description

Technical Field

[0002] In the manufacturing process of automobiles, air conditioners and other equipment, because there are more gases or liquids flowing inside, there are more pipes for gas or liquid circulation inside. Among them, short metal pipes such as copper pipes are commonly used metal short pipes. Copper pipes are generally installed in corresponding positions by welding and other methods. In order to facilitate installation, it is usually necessary to expand or shrink the ends of the copper pipes during processing to meet the installation needs of the staff. For example, a pipe expansion and shrinking machine with Chinese patent application number CN202221742288.6 includes a base plate, and a movable block is arranged on the top surface of the base plate; a fixed component is arranged on the movable block The top surface is used to fix copper tubes of different sizes. The driving motor and the screw rod cooperate with each other to make the movable block drive the placement plate, the arc plate and the pipes between the arc plates to move, so that the staff can move the pipes according to the needs. The connecting plate, the mounting column, the spring, the connecting column and the arc plate cooperate with each other, so that the connecting column drives the arc plate to move to both sides and separates the two arc plates at the same time. The staff places copper tubes of different sizes between the two arc plates. The connecting plate, the spring, the connecting column and the arc plate cooperate with each other to restrict the pipes between the two arc plates, so as to achieve the fixing effect of pipes of different sizes, which is convenient for the staff to expand and shrink the pipes later.
