Skew nylon tires are composed of multi-layer oblique nylon cord plies, and the carcass of radial steel cords consists of a layer of fired steel cord plies. Multi-layer steel belts fixed the crown.
Meridian wire tire sidewall and tread cord function independent, large grounding area. The carcass is composed of a single steel ply and the travel temperature is low. The crown is fixed by a wire belt and can be used to resist thorns and tears. Tread marks wear evenly, and tires have a long life. The dense composition of steel cords, anti-fatigue strength, stretching function has a great degree of improvement. In comparison, the radial steel tires have become more and more excellent.
The deformation of the nylon tire sidewall of the skew line directly affects the tread, the ground contact area of ​​the tire is easy to change, and the wear of the carcass ply wears and causes internal heat. The radial steel wire tires, the deformation of the sidewall is not easy to transmit to the tread, the deformation of the ground contact area is kept constant, the tire temperature is low, and the fuel consumption is lower.
The sidewalls of bias tires consist of layers of overlapping plies, and the crown and sidewalls consist of the same ply layout. The entire carcass is composed of multiple layers of diagonal nylon cords. This makes the tire stress gather, the tire tread uneven force, easy to wear center, reducing tire life. The force layer formed by the nylon cord is poor in heat resistance of the nylon, and the nylon cord's tensile force is reduced by replacing the environment with cold and hot during traveling. There will be sudden tying of the tires, resulting in economic losses, as well as great security risks.
Vacuum tires are tubeless pneumatic tires. Vacuum tires have been used more and more widely in cars, buses and trucks for many years. Vacuum tires have high elasticity and wear resistance, and have excellent adhesion and cooling capabilities. In particular, the all-steel radial tire tires are used by the National Tire Association and are transported to the logistics transportation industry for economic use.
All steel radial tires and common inner tires have the following three advantages:
First: anti-puncture safety, vacuum tire appearance is a layer of high-quality rubber, after inflation, the external surface tension increases, the pressure inside and outside the table can be self-styled on the break, once broken, unlike the general tire as soon as possible, Continuous decompression will ensure the safety during high-speed driving.
Second, super wear-resistance saves money. Vacuum tire wheels are larger than the average rim diameter and will not be affected by the heat of the brake drum during driving. Because there is no inner tube and lining tape, the tire and the wheel ring seal are integrated. When the vehicle is running at high speed, the high temperature occurs due to the tire and the road collision, and the heat is directly dissipated in the interior (hot air) through the steel ring. The tire temperature is constant, and the tire is extended. Service life.
Third, low fuel consumption is equal to making money. Vacuum tires are flat tires, and tire crown angle is zero, so it has strong adhesion. Adhere to better travel stability and smaller bumps, which helps dampen and increase speed. The stability is high, the radial runout of the wheel is small, and the resistance is small. So save fuel by 3%.
The mold holder is an indispensable part of mold manufacturing, and its function and characteristics are of great significance in mold manufacturing. This paper will introduce the characteristics and functions of the fine water mouth mold frame in detail, and further explain its importance through case analysis.
The fine water die holder is a template used for injection mold, whose main function is to fix the mold parts and ensure the stable operation of the mold. The fine water die frame is processed with high precision and has the advantages of high strength, high stiffness and anti-fatigue, which makes the mold manufacturing more accurate and efficient. Fine water die frame is widely used in automobile, electronics, home appliances and other industries, providing important technical support for product manufacturing.
The characteristics of the fine water die frame mainly include the following aspects:
1. High precision: The fine water die frame is manufactured by advanced processing equipment to ensure the accuracy and dimensional stability of the template.
2. High strength: The mold frame is made of high-strength materials, which can withstand the high-pressure impact during the injection molding process to ensure the safe operation of the mold.
3. High stiffness: The mold frame has high stiffness, which can ensure that the mold does not deform when subjected to high pressure, so as to produce high-quality products.
4. Anti-fatigue: After special treatment, the fine water die frame has anti-fatigue performance, and can maintain its accuracy and stability for a long time.
In the mold making, the role of the fine water die frame is very important. First of all, it provides a precise installation position for the mold parts, ensuring the stability of the mold. Secondly, the fine water mouth mold frame can withstand various pressures and shocks during the injection process to protect the mold from damage. In addition, the fine water mouth mold can also improve production efficiency, reduce the number of maintenance, and reduce production costs.
Let us through a case to further understand the importance of fine water mouth mold. An auto parts manufacturer encountered frequent mold damage in the production process, resulting in high production costs. After investigation, it was found that the problem was mainly caused by the mold fixing. In order to solve this problem, the company introduced a fine water mouth mold and optimized its design. The fine water mouth die frame made of high strength material can effectively improve the stiffness and strength of the die, so that the die is not easy to deform and damage when subjected to high pressure. At the same time, the high precision machining of the fine water die frame also ensures the accurate installation of the mold parts and reduces the number of maintenance. After this improvement, the production efficiency of the enterprise has been significantly improved, and the production cost has been greatly reduced.
Through the above introduction and analysis, we can see the important role of fine water die frame in mold manufacturing. It not only provides a precise installation position for the mold, but also improves the stiffness and strength of the mold and reduces the production cost. With the continuous development of science and technology, we have reason to believe that the mold will play a more important role in the future, providing more powerful support for the development of the manufacturing industry.
