[0027] Working principle and usage process of the utility model:

[0028] During use, the steel pipe is conveyed into the mounting ring 61 through the conveying device. When the steel pipe contacts the mounting ring 61, guided by the inclined surface 616, the steel pipe enters the mounting ring 61. When the steel pipe contacts the ball 614, as the steel pipe continues to move, the steel pipe presses the ball 614, and the ball 614 pushes the mounting seat 612. The mounting seat 612 drives the slider 6121 to slide in the chute 6111 and compresses the spring 615. As the steel pipe passes through the mounting ring 61, at the same time, the installation switch activates the electric telescopic rod 533, causing the electric telescopic rod 533 to contract and drive the mounting rod 62 to move downward. At the same time, the sliding block 532 slides downward on the track 531, and the storage tank 51 drives the sponge block 52 to slide downward. When the sponge block 52 contacts the outer wall of the steel pipe, the cold-drawing fluid is coated through the extrusion force generated by the downward movement. Then, the electric telescopic rod 533 is closed, and the steel pipe moves forward. After passing through the forming hole 41, the cold-drawing arm 3 is activated, and the steel pipe is pulled for cold drawing through the cold-drawing arm 3. The cold-drawing arm 3 drives the steel pipe to move forward. When the cold drawing of the steel pipe is completed, it is removed from the cold-drawing arm 3, and then the cold-drawing arm 3 is reset for the next operation. Repeat the above operations until all the steel pipes are cold-drawn.
