It should be noted that the terms "electrolyte" and "gelling agent" are conventional materials in the art, and the technical features are not the utility model of the present invention, and therefore, the components of the "electrolyte" and the "gelling agent" are not described in detail.

In the process of cold drawing and cold drawing forming of metal materials, before metal bars and pipes are drawn, rolling is usually carried out, namely, thick ends of metal pipes are rolled into thin ends, a pipe head is generally heated at high temperature firstly in the existing rolling method, then rolling is carried out through manual operation on a rolling machine, however, the size change is large after the head is pricked, and one-time rolling forming cannot be carried out, so that multiple rolling operations are needed, and a worker needs to move a metal bar to enter and exit the rolling machine once without carrying out one-time rolling and move a station, so that the labor intensity of the worker is large, the working efficiency is low, and therefore, in order to overcome the problems, a full-automatic rolling machine is developed, and the structure and the specific principle are as follows:

a full-automatic heading machine comprises

The rolling head mechanism 10 comprises two parallel rollers 11, wherein a plurality of grooves 112 with different sizes are distributed on the rollers 11 along the axial direction; in the heading process, the metal material enters the groove 112, the rollers 11 of the heading mechanism 10 are driven by the driving motor to rotate, and then the grooves 112 in the two oppositely arranged rollers 11 enclose a forming chamber, so that the forming chamber extrudes the metal material, and the heading section of the metal bar is subjected to plastic deformation. In this embodiment, it is further preferable that the plurality of grooves 112 of each roll 11 have a diameter that gradually decreases along the axial direction of the roll 11, so that the outer diameter of the roll segment can be further reduced by moving the metal material into the next adjacent groove every time the rolling operation is completed during the rolling process. Furthermore, it is preferable that the groove 112 of the roll is not larger than three quarters of the circumference of the roll 11, that is, the roll 11 has a notch 112, since the forming cavity enclosed by the groove 112 is smaller than the outer diameter of the metal material roll head section, which is unfavorable for the metal material to go into the forming cavity, so that the notch 112 can be provided to further facilitate the metal material to go into the groove 112.
