Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

Embodiment 1, a high-pressure pencil shielding ring crimping mechanism, as shown in fig. 1 and 2, including top board 1 and holding down plate 2 that correspond from top to bottom, the installation frock of top board 1 and holding down plate 2 can adopt traditional mode, and holding down plate 2 sets up on crimping pedestal 3, and top board 1 sets up on punching press actuating mechanism, and punching press actuating mechanism drives top board 1 and presses holding down plate 2 down, carries out the crimping to high-pressure pencil shielding ring 4 that is located between top board 1 and holding down plate 2.

The lower end of the upper pressure plate 1 is provided with an upper pressure port 1-1, the upper end of the lower pressure plate 2 is provided with a lower pressure port 2-1, the inner wall of the upper pressure port 1-1 is provided with a first bulge 1-2, and the inner wall of the lower pressure port 2-1 is provided with a second bulge 2-2. When the high-voltage wire harness shielding ring is processed, the high-voltage wire harness shielding ring is positioned between the upper pressure port 1-1 and the lower pressure port 2-1, the stamping driving mechanism drives the upper pressure plate 1 to be in compression joint with the lower pressure plate 2, when the high-voltage wire harness shielding ring 4 is compressed, as shown in figure 3, the first bulge 1-2 and the second bulge 2-2 can press the concave point 4-1 on the high-voltage wire harness shielding ring 4, the concave point 4-1 ensures the pulling-out force of the high-voltage wire harness shielding ring 4, no flash or crack is generated, the production quality is effectively improved, and the product percent of pass is ensured.
