Abstract

The utility model relates to a rubber spring which pertains to the field of spring. The utility model is characterized in that rim of the metal tube spring body is provided with a tube rubber layer; the metal spring body is covered in the rubber layer; the inner and outer surface of the tube may be column or helix matched with the metal spring; the metal body of the spring is covered in the rubber layer to prevent external erosion. The utility model not only enhances the springy and lengthens the service lie, but also reduces the repairing volume and the product cost effectively.

Description

Rubber spring

Technical field

The utility model belongs to spring, especially relates to a kind of pressure spring.

Background technique

Existing pressure spring, metal pressure spring in particular for metallurgy, mine, chemical industry, traffic transport industry, because its working environment is more abominable, exposed spring metal body generally is subjected to the erosion of weather, dust, acid, alkali element, through use after a while, not only elasticity descends gradually, and metal body is subjected to that burn into gets rusty, oxidation, peel off, cause pressure spring shortening in working life, increase the replacing amount of the amount of maintenance and the spring of equipment, increased working strength of workers and cost of production.

Summary of the invention

The purpose of this utility model is to propose a kind of rubber spring, makes the pressure spring metal body avoid extraneous corrosion, and long service life, and the amount of maintenance of minimizing equipment reduce labor strength, reduce production costs.

The purpose of this utility model is achieved like this: a kind of rubber spring, form by the metal spring body, it is characterized in that the rubber layer that tubular is set all around at the metal spring body of tubular, the metal spring body is included in the rubber layer, the internal and external circumferential of the rubber layer of this tubular surface is cylindrical, also with the corresponding spirality of metal spring body; The metal spring body is removed surface impurity through acid treatment earlier, be coated with two layers of adhesive then on the outer surface, after drying, by different purposes and default thickness encapsulate, send into then in the prefabricated mould, vulcanization forming, is produced qualified rubber spring at the demoulding, finishing, and the metal body of spring wraps in the rubber layer, just can avoid extraneous erosion, not only improve elasticity, prolonged working life, also reduced amount of maintenance and cost of production effectively.

The rubber spring that the utility model proposed, rational in infrastructure, safe and reliable, can avoid extraneous erosion, not only improved elasticity, prolonged working life, also reduced amount of maintenance and cost of production effectively.

Now the rubber spring of in conjunction with the accompanying drawings and embodiments the utility model being carried is further described.

Description of drawings

Fig. 1 is that the rubber spring that the utility model proposes partly cuts open schematic representation.

Among Fig. 1: 1, metal spring body 2, rubber layer

Embodiment

As can be seen from Figure 1: a kind of rubber spring, form by metal spring body 1, it is characterized in that the rubber layer 2 that tubular is set all around at the metal spring body 1 of tubular, metal spring body 1 is included in the rubber layer 2, the internal and external circumferential of the rubber layer 2 of this tubular surface is cylindrical, also with metal spring body 1 corresponding spirality; Metal spring body 1 is removed surface impurity through acid treatment earlier, be coated with two layers of adhesive then on the outer surface, after drying, by different purposes and default thickness encapsulate, send into then in the prefabricated mould, vulcanization forming, is produced qualified rubber spring at the demoulding, finishing, and the metal body of spring wraps in the rubber layer 2, just can avoid extraneous erosion, not only improve elasticity, prolonged working life, also reduced amount of maintenance and cost of production effectively.
