[0002] Cement pipe piles play an important role in construction, railway and other industries. In the Yangtze River Delta and Pearl River Delta regions, due to the geological conditions suitable for the use of pipe piles, the demand for pipe piles has increased sharply, thus quickly forming an emerging industry. Concrete piles are made of concrete, which has the advantages of saving wood and steel, durability and low cost.

[0029] In an embodiment of the present utility model, a slider is provided at the lower end of the sliding block 59, and a sliding groove matching the slider is opened on the inner wall of the outer shell 1. The slider is fixedly connected to the inner wall of the sliding groove, so that the pressing wheel 512 can rotate more smoothly with the center column 3 as the center of the circle, so that the pressing wheel 512 can extrude the steel bar more evenly and the forming effect of the round steel bar is better.

[0030] In an embodiment of the present utility model, there are two groups of sliding blocks 59, and the two groups of sliding blocks 59 are mirror-imaged at both ends of the inner wall of the shell 1, and one group of sliding blocks 59 is fixedly connected to the outer wall of the lower gear 58, and the other group of sliding blocks 59 is fixedly connected to the outer wall of the upper gear 53 through the connecting plate 513.

[0031] In an embodiment of the present utility model, a circular opening is provided on the outer wall of the upper end of the shell 1, and a rectangular opening is provided on the side wall of the shell 1. The upper gear 53 and the lower gear 58 are provided with circular holes consistent with the circular opening at the axis center.

The rotation of the lower bevel gear 56 drives the lower bevel gear 56 to rotate. The gear 58 rotates, and the upper gear 53 and the lower gear 58 rotate in opposite directions, so that the two sets of sliding blocks 59 can move in a mirrored manner. While the sliding block 59 moves, the horizontal electric push rod 510 pushes the connecting seat 511 to make the pressure wheel 512 squeeze the steel bar to be formed. The steel bar to be formed is pressed into a round steel bar through the pressure wheel 512 and the center column 3. At this time, the rotating motor 63 rotates to drive the friction wheel 64 to rotate. The rotation of the friction wheel 64 causes the round steel bar to rotate, causing the pressure wheel 512 to further squeeze it, eliminating the step of transporting the round steel bar and preventing the round steel bar from being deformed during transportation. The center column 3 also makes it difficult for the round steel bar to be deformed during extrusion, thereby improving the welding efficiency of the device.
