Example 1: referring to fig. 1, the rounding tool comprises a truncated cone-shaped rounding block 3, and a limiting block 4 is arranged on the rounding block 3. The limiting block 4 can be cylindrical or in other shapes, mainly limits the pressing height of the pressure mechanism 5, is designed in advance according to the diameter and the length of a pipe, and has the same height as the socket pressing type pipe fitting 1 pressed in place.
During shaping, the welding end 2 of the socket pressing type pipe fitting 1 is buckled into the shaping block 3 from top to bottom, at the moment, the socket pressing type pipe fitting 1 is not stressed, and the top height of the socket pressing type pipe fitting is higher than the top of the shaping block 3 necessarily due to the difference ∅ D. When the pressure mechanism 5 presses downwards, the socket pressing type pipe fitting 1 is pushed downwards. In order to avoid the deformation of the pipe caused by excessive pressing, the pressing stroke of the pressure mechanism 5 is set in advance according to the height and the diameter of the pipe, and the method comprises the following steps: determining the inner diameter of the shaped socket pressing type pipe fitting 1, finding a ring with the same size as the inner diameter on the shaping block 3, taking the ring as the bottom, taking the top of the limiting block 4 as the top, and taking the distance between the top and the bottom as the integral length of the pipe. The position where the pressure mechanism 5 presses down, namely, the top of the limiting block 4. Therefore, the rounding operation can be completed, and the deformation of the pipe fitting caused by excessive pressing can be avoided. However, the structure is not suitable for pipes with different sizes, and has low production efficiency and high production cost. Can not be used repeatedly after being worn.

Referring to fig. 2 in an initial state of the utility model, when a pipe or a pipe fitting needs to be shaped, a specific position is determined according to the diameter size of a welding end 2 required by a socket-press type pipe fitting 1, for example, the diameter size is just positioned in a main shaping block 7, and the main shaping block 7 is used for shaping. The position of a ring with the same diameter size is found on the main shaping block 7, the ring is used as the bottom, the height of the socket pressing type pipe fitting 1 is high, the top height of the limiting body 11 is determined, and the nut 10 is rotated to drive the limiting body 11 to move up and down to the required top height. The pressing height of the press mechanism 5 is set, and the pressing height is the top height.
