Spring high-pressure and high-torsion combination machine and spring preparation method

Abstract

The invention belongs to the technical field of spring production, and discloses a spring high-pressure and high-torsion combined machine which comprises a drying oven and a conveying belt which is arranged in the drying oven, extends out of the drying oven and is used for conveying springs, and a clamping module used for grabbing the springs is arranged on the conveying belt at an outlet of the drying oven. The two sides of the clamping end of the clamping module are provided with a fixing module and a pushing module which are matched with each other and used for forcedly twisting and forcedly pressing a spring correspondingly. The fixing module comprises a fixing frame arranged on one side of the clamping end, and a sleeve used for loading a spring is arranged at the top of the fixing frame. The propelling module comprises a plurality of long rods, a first driving part used for propelling the long rods to enable the long rods to be matched with the sleeve to forcedly press the spring, and a second driving part used for rotating the long rods to forcedly twist the spring. The invention further discloses a preparation method of the spring with high elasticity and high torsion. The service life of the prepared spring is prolonged under the high-temperature working condition.

Description

technical field [0001] The invention belongs to the technical field of spring production, and in particular relates to a spring strong pressure and strong torsion combination machine and a spring preparation method. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. [0003] With the development of spring technology, there is now a certain performance requirement for the spring to work under high temperature conditions; if the spring needs to maintain good and stable elastic force and torsion under high temperature conditions, it is necessary to carry out hot and strong pressure and strong torsion during spring processing deal with. [0004] Chinese patent 201210334443.5 discloses a spring hot pressing device, including a frame, a rotating shaft is arranged on the frame, and a rotatabl...

AI Technical Summary

Problems solved by technology

[0007] The device can complete the strong torsion treatment of the torsion spring without the help of complicated special equipment; however, the device only performs strong torsion on the spring, and cannot perform strong compression and strong torsion operations on the spring at the same time

[0008] Simultaneous compression and torsion of the spring seems to be a relatively simple patchwork in technology, but none of the existing technologies can simultaneously perform strong torsion on the spring, and simply force and torsion the spring, and The elastic force and torsion of the spring cannot be greatly improved, and it may also be because the spring is subjected to strong pressure and strong torsion at the same time, which exceeds the bearing range of the spring itself, causing the spring to crack and the quality of the spring will not increase but decrease.
