With the continuous development of science and technology, new forging technology continues to emerge, providing a more efficient and high-quality method for the production of the main and auxiliary connecting rod of the locomotive. These new technologies can not only improve product quality, but also reduce production costs, bringing tangible benefits to manufacturers and users. This paper will discuss the application and advantages of new forging technology in the production of locomotive main and auxiliary connecting rod.
New types of forging technology
Hot forging technology: Hot forging technology is a method of plastic processing of metals at high temperatures. By heating the metal until it is austenitized, giving it good plasticity, it can be forged more easily. Hot forging technology can improve the fluidity and plasticity of the metal and reduce the cracking and deformation during forging.
Warm forging technology: Warm forging technology is a forging method between cold forging and hot forging. The metal has good plasticity at warm forging temperature, while avoiding high energy consumption and material oxidation problems during hot forging. Warm forging technology can improve the utilization rate of materials and the accuracy of products.
Cold forging technology: Cold forging technology is a method of plastic processing of metal at room temperature. Because the metal has good hardness and stability at room temperature, cold forging technology can produce high-precision, high-strength parts. Cold forging technology can reduce energy consumption and material waste, improve production efficiency.
Application of new forging technology in the production of main and auxiliary connecting rod of locomotive
Precision forging: Precision forging is a technology that combines high-precision and high-efficiency forging process with advanced mold design. By precision forging, the locomotive main and auxiliary connecting rod with complex shape and high precision can be manufactured. Precision forging can improve product quality and performance, reduce subsequent processing and finishing work.
Hydroforming: Hydroforming is a technology that uses a liquid medium instead of the traditional stamping process to form metals. In the production of locomotive main and auxiliary links, hydraulic forming can produce links with complex cross sections and precise dimensions. Hydroforming can improve material utilization and product performance, and reduce production costs and energy consumption.
Laser shock strengthening: Laser shock strengthening is a technology that uses high energy laser beams to impact metal surfaces. The surface hardness and fatigue strength of main and auxiliary connecting rod of locomotive can be improved by laser shock strengthening. Laser shock strengthening can extend the service life of products and improve safety.
Additive manufacturing: Additive manufacturing is a direct manufacturing method of metal parts based on 3D printing technology. In the production of locomotive main and auxiliary links, additive manufacturing can produce links with complex internal structures and precise dimensions. Additive manufacturing can shorten the product development cycle, reduce production costs, and improve the ability to customize production.
This paper introduces the application and advantages of new forging technology in the production of main and auxiliary connecting rod of locomotive. These new forging technologies can improve product quality, reduce production costs, improve production efficiency, and bring real benefits to manufacturers and users. In order to better apply these new forging technologies, it is recommended that manufacturers:
Continue to pay attention to the latest development of new forging technology, timely introduction of advanced technology suitable for their own production needs;
Strengthen the investment in technology research and development and innovation, and constantly improve their own technical level and innovation ability;
Strengthen cooperation and exchanges with universities, scientific research institutions, etc., and jointly promote the progress and application of new forging technology;
Pay attention to personnel training and technical training, improve the technical quality and skill level of employees;
Combined with market demand and user feedback, constantly optimize product design and production process, improve product quality and competitiveness.
