Problems solved by technology

Due to these size limitations, if a cylindrical spring with ordinary round steel wire is used in the pump, the spring will bend and deform during compression, resulting in early failure of the spring. If special-shaped steel wire is used to meet the performance requirements, the cost of the spring will be greatly increased

Embodiment Construction

[0014] The invention provides a horn-shaped compression spring, which is mainly used in the environment where the installation space is narrow and long, especially the compression spring in the oil pump, the spring length is required to be longer, and the horn-shaped configuration enlarges the contact area between the compression spring and the counterpart. In order to increase the uniformity of the load and prevent the compression spring itself from being deformed and bent due to the load, the performance of the compression spring will be reduced.

[0015] like figure 1 As shown, the compression spring of the present invention includes a spring body, the spring body is formed by curling and stacking metal wires, the cross section of the metal wires is circular, the spring body is a horn-shaped structure, and its upper end is a cylindrical part , the lower end is a frustum-shaped part. Regarding the selection of spring raw materials, although the special-shaped steel wire ha...

Abstract

The invention provides a horn-shaped compression spring. The horn-shaped compression spring comprises a spring body, the spring body is formed by curling and overlaying metal wires, the cross section of the metal wires is round, the spring body is of a horn-shaped structure, the upper end of the spring body is a cylindrical part, and the lower end of the spring body is a cone-frustum-shaped part. The compression spring is changed to be of a horn shape, the contact area between the compression spring and an opponent is increased so as to increase the evenness of load stress, and it is avoided that the compression spring deforms because of loads, and performance of the compression is reduced because of bending.

Description

technical field [0001] The invention relates to the technical field of compression springs, in particular to a horn-shaped compression spring used in an oil pump. Background technique [0002] With the rapid development of my country's automobile industry, the demand for molds in the automobile industry is increasing. In stamping and plastic molds, elastic elements, especially compression springs, are widely used for pushing, unloading, ejecting, and reset. In actual use, due to the existence of the early failure of the spring, it not only increases the workload of mold maintenance, but also affects the normal production. The early failure of the mold spring is not only the quality of the spring itself, but also the coordination between the spring and the counterpart. There are also some problems. [0003] In particular, the spring in the oil pump has higher requirements. The internal space of the oil pump is small, the top connection port space is narrow, the pump body ...
