Detailed ways

The technical solution of this patent will be further described in detail below in conjunction with specific implementation modes.

Example

Please refer to Figure 1-3, a mechanical parts processing stamping machine includes a processing box 1 and stamping parts 14, and also includes:

The mounting frame 2 is installed on the inner wall of the processing box 1. The mold 3 is fixedly installed on the mounting frame 2. The cylinder 4 is fixedly installed on the top wall of the processing box 1. The telescopic end of the cylinder 4 is fixedly connected to the movable frame 5. The movable frame 5 is fixed on the mounting frame 2. The pressure plate 6 is installed. The movable frame 5 is equipped with a pre-tightening mechanism for pre-tightening the stamping parts 14. The bottom wall of the processing box 1 is provided with an ejection mechanism for ejecting the stamped parts 14. Mold 3.

The pre-tightening mechanism includes an annularly distributed sleeve 9 installed on the movable frame 5. A spring 10 is provided inside the sleeve 9. One end of the spring 10 away from the sleeve 9 is connected to the sliding plate 11. The sliding plate 11 slides with the inner wall of the sleeve 9. The sliding plate 11 is fixedly connected to the annular preloading plate 7 through the sliding rod 12. The surface of the preloading plate 7 is covered with a rubber pad 8. The rubber pad 8 is provided to prevent the preloading plate 7 from clamping the stamping part 14. .

A guide rod 13 is provided between the mounting frame 2 and the top wall of the processing box 1. The guide rod 13 is slidingly connected to the movable frame 5 to increase the stability of the movable frame 5 when it is raised and lowered.

The ejection mechanism includes an ejector rod 15 that is slidably arranged in the mold 3 and distributed in an annular shape. One end of the ejector rod 15 passes through the mold 3 and is fixedly connected to the moving plate 16. The moving plate 16 is connected with a pop-up part, and the pop-up part includes The limit frames 17 are installed on both sides of the bottom wall of the processing box 1.
