Magazine spring and manufacturing method thereof

Abstract

The invention discloses a magazine spring and a manufacturing method thereof in the technical field of magazine springs. A magazine spring body is included. The left end of the magazine spring body isprovided with a bearing spring section. A transition section is arranged at the right end of the magazine spring body. The right end of the transition section is provided with a supporting spring section. The magazine spring body, the bearing spring section, the transition section and the supporting spring section are an integrally-formed left-handed rotation spring and are the same in outer diameter, and the machining precision is higher. Meanwhile, an automatic spring reeling machine and other traditional spring manufacturing technologies can be overcome, and the situation that in the magazine spring shot charging and conveying process, torsion deformation and mutual friction happen, and the shot charging efficiency and the shot conveying reliability are influenced is avoided. Meanwhile, the pitch of the supporting spring section and the transition section is larger than that of the bearing spring section, on the premise that the shot conveying reliability is guaranteed, the free length of the magazine spring is reduced, accordingly, the used stress is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of support springs, in particular to a support spring and a manufacturing method thereof. Background technique [0002] At present, the processing method of spring is mainly coiling method, and the equipment used is mainly automatic spring coiling machine. According to the required length of the spring, the spring steel wire is cut off at the right time, and then the spring broken end is ground, the spring is shaped, and the heat treatment is carried out. For this reason, we propose a support spring and a manufacturing method thereof. Contents of the invention [0003] The object of the present invention is to provide a support spring and a manufacturing method thereof, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a support spring and its manufacturing metho...
