Method for manufacturing fiber strengthening composite helical spring

Abstract

The invention relates to a manufacturing method for a fiber strengthening compound coil spring, comprising the following steps: a fiber reinforced resin continuous bundle which is impregnated in thermosetting resin is led into a screw thread groove of a drive screw component; by the operation of the screw component, the fiber reinforced resin continuous bundle is led into the screw thread groove in a spiral way and then is pushed and moves forward; meanwhile, thermal energy is provided to heat and solidify the thermosetting resin on the fiber reinforced resin continuous bundle, thereby the heated and solidified fiber strengthening compound coil spring can be squeezed out continuously along the axial direction of the drive screw component and is cut into segments according to the required size to form the finished goods of the fiber strengthening compound coil spring needed.

Description

technical field [0001] The invention relates to a method for manufacturing a fiber-reinforced composite helical spring, in particular to a method for continuously producing a fiber-reinforced composite helical spring. Background technique [0002] Currently known various coil springs are widely used in various mechanisms, such as suspension and shock absorbing systems of various vehicles, or general industrial machinery, and most coil springs are all made of metal materials such as steel. Using the elastic recovery ability of the material itself, the coil spring can absorb the axial force. [0003] Generally speaking, although springs made of metal materials have excellent elasticity, they also have the problem of bulky quality. At present, general vehicles are developing in the direction of light weight, in order to achieve the goal of saving energy and increasing sports performance, such as High-strength and light-weight materials such as carbon fiber, aluminum, magnesium...

AI Technical Summary

Problems solved by technology

[0007] Looking at the common features of the above-mentioned known composite material coil spring manufacturing methods, it is not difficult to find that there are still some deficiencies. The main crux lies in its manufacturing process, from the material into the mold, heating, cooling to taking out or peeling off the finished product. If the time is too long, the turnover rate of the mold is low. If you want to mass-produce, you need to prepare a lot of molds, heating equipment, manpower and space, and you have to face the problems of time-consuming production process and poor production efficiency.
