A lower die Y-axis pushing mechanism 10 for supporting and pushing the lower die is installed on one side of the top of the lower case 1. The staff fixes the lower die to be used on the movable end of the lower die Y-axis pushing mechanism 10;

[0019] Vertical profiles 5 are fixed on both sides of the top of the lower chassis 1, and a crossbeam 7 is fixed on one side of the surface of the two vertical profiles 5. A double-axis blanking component 8 is installed on the surface of the crossbeam 7. The Z-axis movable end of the double-axis blanking component 8 is installed with an electric clamp 9. A PLC control panel 6 is installed on one side of the surface of the lower chassis 1. The output end of the PLC control panel 6 is electrically connected to the input end of the hydraulic press body 3, the double-axis blanking component 8, the electric clamp 9 and the lower mold Y-axis push mechanism 10. When the staff turns on the lower mold Y-axis push mechanism 10 through the PLC control panel 6 to work, the lower mold Y-axis push mechanism 10 actively sends the lower mold and the workpiece out of the hydraulic press body 3.

[0020] The double-axis material unloading component 8 drives the electric clamp 9 to move in the X-axis and Y-axis directions. When the electric clamp 9 is driven by the double-axis material unloading component 8 to the top of the lower die and the workpiece, the double-axis material unloading component 8 drives the electric clamp 9 downward again until the electric clamp 9 actively picks up the workpiece, and then the double-axis material unloading component 8 drives the electric clamp 9 to reset its spatial position;

[0021] The hydraulic press body 3 includes four mutually symmetrical guide columns 301 fixed on the top of the lower case 1, a fixed plate 302 is fixed on the top of the four guide columns 301, a slide plate 303 is slidably installed on the surface of the guide column 301 below the fixed plate 302, a hydraulic cylinder 4 is installed on the top of the fixed plate 302, the bottom end of the piston rod of the hydraulic cylinder 4 is fixedly connected to the top of the slide plate 303, the input end of the hydraulic cylinder 4 is electrically connected to the output end of the PLC control panel 6, when pressing the workpiece, the slide plate 303 and the upper die are driven downward by the hydraulic cylinder 4 until the upper die and the lower die complete the mold closing operation, and the pressed workpiece is retained in the lower die;

[0022] The lower die Y-axis pushing mechanism 10 includes a Y-axis cylinder 1001 installed on the top of the lower chassis 1, and a slide 1002 installed on the top of the piston rod of the Y-axis cylinder 1001. The slide 1002 is used to fix the lower die. Right-angle guide rails are fixed on both sides of the top of the lower chassis 1. The top of the right-angle guide rails slides with the top of the slide 1002. The input end of the Y-axis cylinder 1001 is electrically connected to the output end of the PLC control panel 6. When the upper die and the lower die are separated, the Y-axis cylinder 1001 actively pushes the slide 1002, the lower die and the pressed workpiece to exit the outside of the hydraulic press body 3.

The bottom end of the arm 803 is fixedly connected to the top end of the electric clamp 9. The surface of the crossbeam 7 and the back of the arm 803 are respectively provided with an X-axis gear transfer mechanism 802 and a Z-axis gear transfer mechanism 804. The X-axis gear transfer mechanism 802 includes a helical rack mounted on the surface of the crossbeam 7, and a stepper motor mounted on the surface of the slide 801. A helical gear is mounted on the output end of the stepper motor. The helical gear and the helical rack are meshed with each other. The X-axis gear transfer mechanism 802 controls the positions of the slide 801, the arm 803, the electric clamp 9 and other components in the X-axis direction, while the Z-axis gear transfer mechanism 804 controls the positions of the arm 803 and the electric clamp 9 on the Z-axis. In this process, the electric clamp 9 moves flexibly, and the electric clamp 9 can adapt to workpieces of different shapes, sizes and materials, so as to achieve the purpose of stably picking up workpieces.

[0024] Pulleys are installed on both sides of the surface of the slide 801, and the outer wall of the vertical arm 803 and the pulleys are in contact with each other, so that the lifting stability of the vertical arm 803 is improved by the pulleys.

[0025] When the embodiment of the present application is in use, the staff first fixes the lower mold to be used on the movable end of the lower mold Y-axis pushing mechanism 10, and the upper mold is installed on the movable end of the hydraulic press body 3. The hydraulic press body 3 drives the upper mold to approach the lower mold. When a metal workpiece is located in the lower mold, the pressing operation of the workpiece is completed by closing the upper and lower molds. After the upper and lower molds are separated, the staff turns on the lower mold Y-axis pushing mechanism 10 through the PLC control panel 6 to work. The lower mold Y-axis pushing mechanism 10 actively sends the lower mold and the workpiece out of the hydraulic press body 3, and the lower mold and the electric clamp 9 are on the same reference plane. At this time, the double-axis blanking component 8 is in action, and the double-axis blanking component 8 drives the electric clamp 9 to move in the X-axis and Y-axis directions. Move upward, that is, the electric clamp 9 moves in the X-axis direction first. When the electric clamp 9 is driven by the double-axis unloading component 8 to the top of the lower mold and the workpiece, the double-axis unloading component 8 drives the electric clamp 9 downward again until the electric clamp 9 actively picks up the workpiece. Then the double-axis unloading component 8 drives the electric clamp 9 to reset the spatial position, and the electric clamp 9 actively releases the workpiece to complete the unloading operation of the workpiece. The equipment realizes automatic unloading operation of the workpiece by introducing the lower mold Y-axis pushing mechanism 10, the double-axis unloading component 8, the electric clamp 9 and other components, reducing the need for manual intervention, and can complete the workpiece unloading process more quickly and accurately. Compared with manual operation, it significantly improves the production efficiency of the production line and reduces the safety risks associated with manual operation.
