Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat setting machine accessories, and in particular to an amplitude adjusting nut used in a heat setting machine. Background Technology
[0002] In high-temperature, high-friction environments such as heat setting machines, the amplitude adjusting nut, as a critical connecting component, needs to possess excellent high-temperature resistance, wear resistance, and fatigue resistance. Traditional amplitude adjusting nuts are mostly made of a single metal material (such as copper) or ordinary plastic materials (such as nylon or PTFE), which presents the following problems:
[0003] 1. Metal materials are prone to thermal expansion at high temperatures, which affects dimensional accuracy;
[0004] 2. Ordinary plastics lack sufficient wear resistance and strength, making it difficult to meet the needs of long-term use;
[0005] 3. A single material structure cannot simultaneously meet the requirements of lightweight and high strength.
[0006] In the existing technology, although there are some patents for improvements to the amplitude adjusting nut, most of them focus on thread optimization or surface treatment, and lack comprehensive performance optimization for high temperature and high friction environments. Utility Model Content
[0007] To address the performance limitations of existing amplitude adjustment nuts in high-friction environments, this invention provides an amplitude adjustment nut for use in heat setting machines that improves structural strength and adapts to high-friction environments.
[0008] The technical solution adopted by this utility model to solve its technical problem is:
[0009] An adjustable nut for use in a heat setting machine includes a shell and an inner layer. The inner layer has internal threads on its inner side. The shell is made of metal and has a ring structure. The inner layer is injection molded into the inner side of the shell.
[0010] Furthermore, the outer shell is formed by assembling and fixing at least two shell units.
[0011] Furthermore, at least one edge of the housing unit is provided with a barb forming cavity, which has a radially extending forming area and a circumferentially extending forming area. The barb forming cavity is used to form the corresponding barb structure. The barb structure prevents the inner layer material from falling off under high temperature or high frequency vibration environments.
[0012] Furthermore, the shell unit has barb forming cavities on both sides, and a double barb composed of two symmetrical barb structures is formed on the inner layer.
[0013] Furthermore, the angle between the lines connecting the two sides of the double barbs to the center of the inner layer is 30° to 60°. This angle ensures the stability of the inner layer structure.
[0014] Furthermore, the difference between the outer diameter of the double barbs and the inner diameter of the inner layer is 12-13 mm.
[0015] Furthermore, the inner side of the housing unit is provided with several concave cavities, and the inner layer is formed into corresponding convex parts.
[0016] Furthermore, the outer shell is made of aluminum alloy and is formed by die casting.
[0017] Furthermore, the inner layer is made of short-cut carbon fiber reinforced polyetheretherketone composite material.
[0018] Furthermore, adjacent housing units are secured with screws and nuts.
[0019] Beneficial effects:
[0020] (1) The inner layer of this utility model adopts a one-time inlay injection molding process to tightly combine the aluminum alloy shell with the inner layer, which is conducive to efficient mass production. The bonding strength is more than 20% higher than that of the traditional assembly process, which significantly improves the strength and wear resistance of the nut and is suitable for high friction environment.
[0021] (2) One-time inlay injection molding process improves production efficiency and reduces manufacturing costs;
[0022] (3) The outer shell is made of aluminum alloy material and is formed by die casting; the inner layer is made of polyether ether ketone material modified with added short fiber carbon fiber. Both the aluminum alloy outer shell and the modified polyether ether ketone inner layer are low-density high-strength engineering materials. While ensuring strength, the overall weight is reduced. It is combined with the aluminum alloy outer shell by one-time inlay injection molding, and has excellent high temperature resistance, wear resistance and fatigue resistance.
[0023] (4) Modified polyetheretherketone materials have stable performance in high-temperature environments of 250-260℃, making them suitable for high-temperature applications such as heat setting machines;
[0024] (5) The inner shell is designed with a barbed cavity structure with a barb angle of 30 to 60°, a depth of 12 to 13 mm, and a quantity of 4 to 8, to ensure that the inner layer material will not fall off or loosen under high temperature and vibration environment, and to ensure long-term stability.

[0037] like Figures 1-4 This invention relates to an amplitude-adjusting nut for use in a heat-setting machine, comprising a shell 1 and an inner layer 2. The inner layer 2 has internal threads on its inner side. The shell 1 is made of metal and has a ring-shaped structure. The inner layer 2 is injection molded into the inner side of the shell 1. The inner layer 2 is tightly bonded to the shell 1 through a one-time injection molding process. In a preferred embodiment, the shell 1 is made of ADC12 aluminum alloy and formed by die casting to ensure its lightweight and high strength. The inner layer 2 is made of short-cut carbon fiber reinforced polyetheretherketone composite material. The aluminum alloy shell is placed in a mold, and the modified polyetheretherketone inner layer is formed through a one-time injection molding process to ensure a tight bond between the two. The inner layer uses polyetheretherketone material modified with 30% short-fiber carbon fiber. It has advantages such as high temperature resistance, high strength, and light weight. After injection molding, the internal threads are machined to achieve ISO 7 grade accuracy, ensuring precise fit and reliable connection with the screw. The surface of the shell 1 is anodized to enhance the corrosion resistance and surface hardness of the metal.
[0038] The outer shell 1 is formed by assembling and fixing at least two shell units 1-1. Optionally, such as... Figure 1 As shown, adjacent housing units 1-1 are fixed by screws 3 and nuts 4.
[0039] At least one side edge of the housing unit 1-1 is provided with a barb forming cavity 1-11. The barb forming cavity 1-11 is provided with a radial forming area 1-111 extending in the radial direction and a circumferential forming area 1-112 extending in the circumferential direction. The barb forming cavity 1-11 is used to form the corresponding barb structure 2-11.
[0040] Preferably, barb forming cavities 1-11 are provided on both sides of the shell unit 1-1, and a double barb 2-1 composed of two symmetrical barb structures 2-11 is formed on the inner layer 2.
[0041] The angle α between the two sides of the double barbs 2-1 and the center of the inner layer 2 is 30° to 60°. The difference D between the outer diameter of the double barbs 2-1 and the inner diameter of the inner layer 2 is 12 to 13 mm. The number of barbs is 4 to 8, which can effectively prevent the inner layer material from falling off under high temperature and vibration environments.
[0042] The inner side of the shell unit 1-1 is provided with several concave cavities 1-12, and the inner layer 2 is formed into corresponding convex parts 2-2.
[0043] This utility model discloses an amplitude-adjusting nut, which is a cylindrical amplitude-adjusting nut with an aluminum alloy shell covering a modified polyether ether ketone inner layer. Through optimized material combination and structural design, it achieves comprehensive performance of high strength, wear resistance, high temperature resistance and lightweight. It is suitable for mechanical connections in high temperature and high friction environments, especially for mechanical connections in high temperature and high friction environments such as heat setting machines. It solves the problem of insufficient performance of traditional amplitude-adjusting nuts in high temperature and high friction environments and has broad application prospects.
[0044] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
