The driving motor 7 is a stepper motor, which has the advantages of precise positioning, low cost and simple control. The slider 8, the synchronous belt 4 and the driving motor 7 constitute a synchronous belt linear module 12. A wire pressing rod 13 is arranged on the synchronous belt linear module. The setting of the wire pressing rod 13 can fix one end of the metal part before the metal part is pierced through the mold. The synchronous belt linear module 12 is provided with two groups, and is mirror-symmetrical about the slide rail 6. This setting can improve work efficiency. A slide rail 6 is installed in parallel with a guide rail 15 on multiple brackets 3. The slide rail 6 is slidingly provided with a first A pneumatic shearing tool 10 and a second pneumatic shearing tool 11. Taking this embodiment as an example, the pneumatic shearing of the first pneumatic shearing fixture 10 is a thick end shearing tool for cutting off the thick end part, and the pneumatic shearing fixture of the second pneumatic shearing fixture 11 is used to cut off the thin end part. A bracket is fixedly connected to a mold box 2 through a mold box mounting bracket 17. The mold box 2 is located beside the other end of the guide rail 15. The mold 1 includes an upper mold 1a and a lower mold 1b. The upper mold 1a is fixedly installed in the mold box 2, and the lower mold 1b is fixedly connected to the piston rod of a top pressure cylinder 5, sliding Fitted in the mold box 2, the upper mold 1a is provided with a positioning pin 16, which is used for positioning when the mold 1 is separated and combined. The upper and lower mold surfaces are provided with an extrusion hole 1c, which is formed by closing the semicircular grooves provided on the upper and lower molds. The semicircular grooves of the upper and lower molds are both conical grooves, the large end of the conical groove is the inlet concession end, and the small end is the forming end. The extrusion hole 1c is set to prevent the metal parts from being subjected to shear force, and there is no need to repeatedly set the head and repeatedly penetrate the mold. The middle of the conical grooves of the upper and lower molds is the forming part, and the front and rear ends are trumpet-shaped concession holes 14. This setting can reduce the difficulty of processing, improve processing accuracy, and also reduce costs.

[0018] During operation, the metal part is fixed by the wire pressing rod, and then inserted into the mold box. The mold box is closed first, and the thin end of the metal part is pulled first. One end of the metal part is clamped by the first pneumatic clamping device, and the synchronous belt linear module is driven by the stepper motor to drive the first pneumatic clamping device on the slide block to make a linear motion. When the thin end reaches the specified length, the first pneumatic clamp is released, and then the metal part is clamped by the second pneumatic clamping device, and then the upper and lower molds of the mold box are separated to pull the thick end in air. At this time, the second pneumatic clamping device is pulled, and the pneumatic clamp of the first pneumatic clamp is separated and reset under the action of the synchronous belt linear module. At the same time, the separation of the pneumatic clamp does not hinder the movement of the second pneumatic clamp. When the specified length is reached, the pulling stops, and then the metal is sheared by adjusting the position of the first shearing tool and the second shearing tool on the slide rail. The above operations are repeated to complete the drawing and blanking of metal functional parts with different diameters.
