Carbon fiber composite material spring forming mold and method

Abstract

The invention discloses a carbon fiber composite material spring forming mold. The forming mold comprises an outer mold set and a core mold set arranged in the outer mold set. The core mold set comprises an inner mold core rod and a plurality of sector-shaped sliding blocks. Core rod protruding blocks with the number equal to that of the sector-shaped sliding blocks are uniformly arranged on the outer wall of the inner mold core rod; sliding block grooves are formed in the inner walls of the sector-shaped sliding blocks; sliding block spring lines are designed on the outer walls of the sector-shaped sliding blocks; sliding block protruding blocks are symmetrically arranged at the top edges of the two ends of the corresponding sector-shaped sliding blocks; and rotary disks are arranged at the two ends of the sector-shaped sliding blocks. The continuous carbon fiber composite material spring forming mold is reasonable and simple in structure; a carbon fiber composite material spring can be formed through the core mold set composed of the inner mold core rod which can be designed in different specifications and the multiple sector-shaped sliding blocks, and the diameter of the spring can be adjusted as required; and in addition, the forming process is convenient, the forming period is short, and an adopted material is good in strength, corrosion resistance, resistance to chemical product corrosion and the like.

Description

technical field [0001] The invention relates to a carbon fiber composite material spring, in particular to a carbon fiber composite material spring forming die and a forming method thereof, belonging to the technical field of forming dies. Background technique [0002] As one of the most commonly used mechanical basic parts, springs are used to control the movement of parts, alleviate shocks or vibrations, store energy, measure force, etc., and are widely used in various mechanical equipment. The main materials for making springs are high-quality carbon steel, alloy steel, non-ferrous metal alloys, etc. However, metal springs also have many shortcomings, such as easy to rust, not resistant to corrosion, and heavy in weight. With the development of science and technology, it is of great significance to develop a continuous carbon fiber composite material spring with high rigidity and obvious weight reduction effect. [0003] Carbon fiber materials have been used in various f...

Problems solved by technology

[0004] However, few of the existing reed pipe forming molds are specially designed to face the carbon fiber composite coil spring. When the spring pipe is formed, the diameter of the spring cannot be adjusted, the production efficiency is very low, and the quality of the formed product is very unstable.
