A discharge mechanism is provided inside the sliding cavity.

[0006] As a further improvement of the present invention, the feeding mechanism includes a stepping telescopic rod installed on the right side wall of the machine body. The telescopic end of the stepping telescopic rod is fixedly connected to a connecting plate. A loading sleeve is fixedly connected to the side wall of the connecting plate.

[0007] As a further improvement of the present invention, the rotating mechanism includes a vertical rod fixedly connected to the lower end of the moving plate. A limiting sliding groove is provided on the side wall of the vertical rod. A rotating sleeve is embedded in the middle of the turntable through a one-way bearing. The vertical rod is inserted into the rotating sleeve. A vertical groove is provided on the inner top wall of the sliding cavity. The vertical rod is inserted into the vertical groove.

[0008] As a further improvement of the present invention, the pressing mechanism includes a rectangular rod penetrating through and slidably connected to the moving plate.

[0009] As a further improvement of the present invention, the discharging mechanism includes a sliding plate slidably connected inside the sliding cavity. A material ejecting rod is fixedly connected to the upper end of the sliding plate. The material ejecting rod penetrates through the inner top wall of the sliding cavity and extends into the inside of the extrusion cavity.

[0010] As a further improvement of the present invention, the limiting chute is provided with a vertical portion and an arc portion, and the vertical portion is located above the arc portion.

[0011] As a further improvement of the present invention, a locking bolt threadedly connected to it penetrates through the upper side wall of the loading sleeve.

[0012] As a further improvement of the present invention, a stop rod is fixedly connected to the inner top wall of the fixed frame. The stop rod penetrates through the moving plate, and the moving plate is slidably connected to the stop rod.

[0013] Advantages of the present invention:

[0014] 1. By setting the feeding mechanism, the material rod is inserted into the loading sleeve and fixed by the locking bolt. By the contraction of the stepping telescopic rod, the material rod can be driven to move a fixed distance each time, realizing the automatic feeding of the material rod to the supporting block.

[0015] 2. By setting the rotating mechanism, when the hydraulic cylinder extends, it can drive the vertical rod to move downward. Due to the setting of the one-way bearing, the vertical rod will not drive the turntable to rotate when moving downward, thus not affecting the cutting and extrusion forming processing of the material rod. When the hydraulic cylinder drives the vertical rod to move upward, when the moving plate approaches the top of the fixed frame, it can drive the turntable to rotate counterclockwise, and the material rod that has been cut on the right side can be transferred to the lower part of the extrusion head. And when the supporting block contacts the cushion block, due to the jacking action of the cushion block, the supporting block can be jacked up and tilted, so that the material rod in the supporting block falls into the extrusion cavity through the feeding groove, and the cutting and feeding of the material rod can be completed continuously and automatically without manual feeding.

[0016] 3. By setting up a cutting machine and a pressing mechanism, when the hydraulic cylinder extends, it can drive the moving plate to move downward, the pressing block presses on the rod stock, and a downward pressure is applied to the pressing block through the elastic force of the first spring to press the rod stock tightly, ensuring the stability during the slitting of the rod stock. When the moving plate continues to move downward, it can drive the cutting machine to complete the slitting of the rod stock. At the same time of slitting the rod stock, it can drive the extrusion head to move downward to complete the extrusion molding of the rod stock inside the extrusion cavity. The slitting and extrusion molding of the rod stock are carried out simultaneously, effectively improving the processing efficiency.

[0017] 4. By setting up a discharging mechanism, when the vertical rod moves down to the bottom of the sliding cavity, the first magnetic block is magnetically connected to the second magnetic block. When the vertical rod moves upward, it can drive the sliding plate to move upward, and then drive the ejector rod to first lift the extruded cover terminal. When the sliding plate moves upward and contacts the connecting block, it can drive the connecting block to move upward. At this time, the traction rope is relaxed, and the side push plate rotates to the left under the action of the torsion spring, and the already lifted cover terminal can be pushed to the left into the discharge port, realizing the automatic discharging of the cover terminal.

[0018] The present invention can realize the continuous automation of slitting and extrusion molding of the rod stock, and can realize the automatic discharging of the cover terminal after extrusion molding, without manual intervention. The overall processing automation degree is high and the efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The specific unloading mechanism includes a sliding plate 23 slidably connected inside the sliding cavity 22. A top rod 21 is fixedly connected to the upper end of the sliding plate 23. The top rod 21 penetrates through the inner top wall of the sliding cavity 22 and extends into the extrusion cavity 20. A first magnet 24 is fixedly connected to the upper end of the sliding plate 23. A second magnet 30 is fixedly connected to the lower end of the vertical rod 25.

[0032] When the present invention is in use, a material rod is inserted onto the loading sleeve 4 and fixed by a locking bolt 5. By the contraction of the stepping telescopic rod 2, the material rod can be driven to move above the supporting block 16;

[0033] The hydraulic cylinder 11 is started to extend, driving the moving plate 12 and the extrusion rod 13 to move downward. The pressing block 7 presses on the material rod, and a downward pressure is applied to the pressing block 7 through the elastic force of the first spring 9 to press the material rod tightly, ensuring the stability of the material rod during slicing.

When the moving plate 12 approaches the top of the fixed frame 6, it can drive the turntable 17 to rotate counterclockwise, and the material rod that has been slit on the right side can be transferred to the lower part of the extrusion head 14. And when the supporting block 16 contacts the cushion block 15, under the jacking action of the cushion block 15, the supporting block 16 can be jacked up and tilted, so that the material rod in the supporting block 16 falls into the extrusion cavity 20 through the feeding groove 18. The slitting and feeding of the material rod can be continuously and automatically completed without manual feeding. Then, the material rod is continuously fed onto the supporting block 16, and the cold extrusion processing of the cover terminal can be completed by repeating the operation.
