[0059] In the text, both the first stepping motor 602 and the second stepping motor 606 adopt an open-loop control method. Open-loop control is the simplest and most commonly used control method. Its principle is to control the movement of the motor by controlling the pulse signal input to the motor. This method can perform precise control without a feedback signal. The motor can rotate according to the set step angle by receiving the pulse signal, and each pulse signal corresponds to the motor rotating a fixed angle.

[0060] Working principle: When in use, place the lower pressing die 300 at the die mounting hole on the base 1, then place the T-shaped protective ring 302, and then loosen the cover body 503 so that the upper pressing die 500 is placed into the mounting plate 202. At the same time, the upper pressing die 500 is located inside the threaded tube 502. Then tighten the cover body 503 so that the pressing ring 504 on the cover body 503 squeezes against the top of the retaining ring 501, thereby positioning the upper pressing die 500. Subsequently, put metallurgical powder into the inside of the lower pressing die 300, control the hydraulic telescopic rod 204 to extend, and the hydraulic telescopic rod 204 drives the upper pressing die 500 on the mounting plate 202 to move downward, thereby pressing the powder in the lower pressing die 300 through the T-shaped protective ring 302. After the pressing is completed, control the hydraulic telescopic rod 204 to contract. Subsequently, the hydraulic telescopic rod 204 drives the limiting plate 201 on the mounting plate 202 to move upward. When the limiting plate 201 moves upward, it will contact the bottom of the touch switch 402. At this time, the touch switch 402 controls the screw rod 603 on the first stepping motor 602 to rotate, thereby moving the slide bar 601 on the slide bar 600, and then driving the square tube 605 on the connecting rod 604 to move towards the T-shaped protective ring 302. When the clamping rod 611 is located on both sides of the T-shaped protective ring 302, the controller controls the second stepping motor 606 to work. The second stepping motor 606 drives the sliding block 608 on the threaded rod 607 to move upward, thereby moving the cross bar 610 and the clamping rod 611 on the push rod 609 upward, so as to facilitate the removal of the T-shaped protective ring 302 when the pressing is completed, avoiding the need for manual removal of components after the pressing is completed.
