specific Embodiment approach 1

[0027] Specific implementation mode one: combine Figure 1 to Figure 3 Describe this embodiment, this embodiment composite material rectangular section spring mold, this mold is made of cylindrical core tube 2 and mold main body 1;

[0028] The mold main body 1 is a helix formed by connecting several helical annular sheets 3;

[0029] The two end faces on the spiral annular sheet 3 are in the same plane, and the plane is parallel to the axis of the spiral annular sheet 3; one of the two end faces on the spiral annular sheet 3 The center is provided with a bump 4, and the center of the other end face of the two end faces on the spiral annular sheet 3 is provided with a pit 5 that fits with the bump 4, and the adjacent bump 4 and the pit 5 form a card slot structure to connect adjacent helical annular sheets 3;

[0030] The mold main body 1 is sleeved on the outside of the cylindrical core tube 2 .

[0031] The present invention has the following beneficial effects:

specific Embodiment approach 2

[0034] Embodiment 2: This embodiment differs from Embodiment 1 in that: the mold body 1 is made of carbon steel or alloy steel. Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0035] Specific embodiment three: the present embodiment utilizes the method for preparing spring of composite material rectangular section spring mold to carry out according to the following steps:

[0036] 1. Assemble the spiral annular sheet 3 into the mold main body 1;

[0037] 2. Set the mold main body 1 on the outside of the cylindrical core tube 2;

[0038] 3. Wind the fiber material in the gap between the adjacent spiral ring-shaped sheets 3 on the mold body 1. During the winding process, apply a pulling force to the fiber material in a direction away from the mold body 1 to keep the fiber material in a stretched state. At the same time, during the winding process Filling resin into the gap of fiber material;

[0039] 4. After step 3 is completed, set the silicone sleeve with an inner diameter smaller than the outer diameter of the mold body 1 on the outside of the mold body 1;

[0040] 5. After step 4 is completed, resin curing and demoulding are carried out, that i...

Abstract

The invention provides a composite rectangular-cross-section spring mould and a method for preparing the springs by using the mould, and relates to a spring mould and a method for preparing springs. The problems that the consuming time is long, the raw material consumption is large, the cost is high, mould-releasing is difficult, and the efficiency is low existing in the preparation process of existing composite spiral springs are solved. The mould is composed of a cylindrical core tube and a mould body, and the mould body is a spiral body which is formed through connection of a plurality of spiral annular piece bodies. The method for preparing the springs by using the composite rectangular-cross-section spring mould comprises the following steps that 1, the mould body is assembled; 2, the mould body is arranged on the outer portion of the cylindrical core tube in a sleeving mode; 3, fiber materials are wound, and resin is filled; 4, a silicon rubber case is arranged on the outer portion of the mould body in a sleeving mode; and 5, solidifying and mould-releasing are conducted. The composite rectangular-cross-section springs prepared by the method have the advantages that the weight is light, the strength is high, and the rigidity is high, the cost of the mould is low, the mould can be used repeatedly, and mould-filling and mould-releasing are easy.

Description

technical field [0001] The invention relates to a spring mold and a spring preparation method. Background technique [0002] Among the new materials, fibers are combined with resins, metals, ceramics and other matrices, and the composite materials made have excellent properties. For example, carbon fiber composite materials with the best performance in composite materials, carbon fibers are generally special fibers composed of carbon elements. Carbon fiber has many excellent properties, such as high melting point, wear resistance, corrosion resistance, etc. At the same time, its surface has obvious anisotropy and is relatively soft. It can be processed into various fabrics and has great strength in the fiber direction. The mechanical properties of carbon fiber composite materials are very good, its specific gravity is less than 1 / 4 of that of steel, its tensile strength can reach 7 to 9 times that of steel, and its tensile modulus of elasticity is also greater than that of ...
