Abstract
A spring shim comprises a shim body, and an inner through hole and a peripheral wall of the shim body. The shim body is made of Cr10 or Cr20 manganese-titanium steels, or Cr20 or Cr40 steels and processed by the quenching or the cementation quenching process in the heat treatment, so the hardness of the shim body or the partial surface shim body or the outside surface shim body can be 46 deg. or above 46 deg. / 60 kilogram pressure hardness.
Description
Technical field
The present invention is that a kind of pad is loaded on the fastening piece accessory on screw or the nut, and more particularly, it is a kind of pad.
Technical background
Known fastening piece pad is nonelastic pad, with screw or nut spinning fastening after, if through fierceness concussion its nut of back or screw very easily falls back, become flexible, it has influenced safe in utilization to some extent.
Summary of the invention
The objective of the invention is provides a kind of simple in structure, easy to make, the technology of the present invention that has good quality for overcoming deficiency of the prior art.
The technical solution adopted for the present invention to solve the technical problems is:
Compression spring of the present invention comprises string dress hole 2 and pad lamellar body periphery wall 3 in pad lamellar body l, the pad lamellar body; On the end face of pad lamellar body 1, be provided with in the pad lamellar body end face of linking body structure and enclose convex surface 4, on the bottom surface of pad lamellar body 1, be provided with in the pad lamellar body bottom surface of linking body structure and enclose recessed empty 4A, on pad lamellar body 1 radius, be provided with the disconnected ditch 5 of l road stretchability elastic force at least; Pad lamellar body 1 adopts 10 chromium-manganese-titanium steel materials or 20 chromium-manganese-titanium steel materials or 20 chrome steels or the 40 chrome steel manufacturings of carbon content 0.1-1.49 ‰, and adopt carburizing quenching process in heat-treatment quenching or the heat treatment to quench to process, its lamellar body hardness or part lamellar body hardness or external layer lamellar body hardness are more than 46 ° or 46 °/60 kilograms of pressure hardness.
The ditch length of the disconnected ditch 5 of described stretchability elastic force is in the length of pad lamellar body 1 radius.
The invention has the beneficial effects as follows:
1, the present invention is being provided with concave space and the disconnected groove structure of stretchability elastic force under the epirelief on the pad lamellar body, and changed steel manufacturing of high quality and at a reasonable price, increased quenching technical, thereby improved its consistency and elasticity, it has solved it at one stroke and has easily fallen back and easily loosening deficiency;
2, after the supporting use of the present invention and screw or nut, can be widely used in to adorn the fixed installation of object to all;
3, the present invention is simple in structure, and is simple for production, and practical reliable, cheap, social benefit is obvious.
