Abstract
The invention provides a novel composite washer, which is formed by adopting a stamping process to punch a through-hole of a flat cushion in one step, performing heat treatment for a spring clip, and negatively and positively embedding in the long-waist-shaped through hole symmetrically. The spring clip can generate a certain elastic force due to the extrusion of a nut; when the spring clip is negatively and positively embedded in the long-waist-shaped through hole symmetrically, and a resistance direction is opposite to a loosing direction of the nut, double functions of a flat washer and a spring washer can be realized; at the same time, as the simple structure of the spring clip, the invention has the advantages of simple manufacturing process and low cost and raw material saving.
Description
Technical field
The present invention designs a kind of packing ring, and particularly a kind of new type compound packing ring belongs to the mechanical parts technical field.
Background technique
At present, in the fastening process of mechanical parts, because use causes the lax of nut for a long time, the connection between the part is unreliable in order to prevent, general plain washer and the spring washer of using supportingly, but plain washer and spring washer all are parts independently separately, not only make comparatively trouble, simultaneously, owing to be independent structures separately, also there is waste material, the defective that cost is higher.
Summary of the invention
The objective of the invention is to: a kind of new type compound packing ring is provided, and this compound packing ring has the dual functions of plain washer and spring washer, and not only manufacturing process is simple, also have save material, lower-cost advantage.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: adopt stamping process, punching out once goes out the plain cushion through hole, and spring clip is heat-treated, in the positive and negative through hole that is embedded in long waist shaped symmetrically of spring clip.
Beneficial effect: because under the extruding of nut, spring clip can produce certain elastic force, be embedded in the through hole of long waist shaped symmetrically and its drag direction when opposite when spring clip is positive and negative with the lax direction of nut, just can realize the dual functions of plain washer and spring washer, simultaneously, because spring clip is simple structure, so, the present invention have manufacturing process simple, save material, lower-cost advantage.
Description of drawings
Fig. 1 is a structure principle chart of the present invention;
Fig. 2 is the shape figure of accompanying drawing 1 medi-spring card;
Shown in the figure: 1, plain cushion; 2, spring clip; 3, through hole.
Specific implementation method
Adopt stamping process, punching out once goes out plain cushion (1) through hole (3), and spring clip (2) is heat-treated, in the positive and negative through hole (3) that is embedded in long waist shaped symmetrically of spring clip (2).
Claims (1)
1. new type compound packing ring, it is to adopt stamping process, and punching out once goes out plain cushion (1) through hole (3), and spring clip (2) is heat-treated, in the positive and negative through hole (3) that is embedded in long waist shaped symmetrically of spring clip (2).
