Locomotive main and auxiliary connecting rod forging is an important part of locomotive, its quality directly affects the performance and safety of locomotive. In this paper, the production technology of locomotive main and auxiliary connecting rod forging will be deeply discussed in order to improve the quality and production efficiency of forging.
The choice of materials is very important in the forging process of locomotive main and auxiliary connecting rod. Commonly used materials include carbon steel, alloy steel, etc., according to specific needs to choose the right material. At the same time, the preparation of materials is also a key link to ensure that the quality, specifications and quantity of materials meet the production requirements.
Forging is the core technology of forging of main and auxiliary connecting rod of locomotive. The following points should be noted in the forging process:
Heating: The material is heated to the right temperature to reduce its plasticity and facilitate forging.
Forging: The material is formed into a preliminary connecting rod shape by forging.
Trimming and rounding: Excess material is removed and the necessary rounding is performed to ensure that the shape and size of the connecting rod meet the requirements.
Heat treatment: Through heat treatment to improve the mechanical properties of the material, such as strength, toughness, etc.
Quality control is a necessary link to ensure the quality of forging. Through strict quality inspection and control, we ensure that every forging meets the quality requirements. Commonly used quality control methods include: size inspection, appearance inspection, non-destructive testing, etc.
Taking the production of the main and auxiliary connecting rod forging of a certain type of locomotive as an example, the production process is analyzed in detail:
Material selection: High strength alloy steel is selected as raw material.
Heating: The raw material is heated to about 1200℃ and kept warm for a period of time.
Forging: Multiple forging at the right temperature to form a preliminary connecting rod shape.
Trimming and shaping: trimming machine and shaping machine are used to trim and shape the wrought connecting rod.
Heat treatment: The connecting rod is quenched to improve its hardness and strength.
Quality inspection: Strict inspection of the size, appearance and non-destructive testing of the connecting rod to ensure qualified quality.
Surface treatment: According to the need, the connecting rod surface treatment, such as spraying anti-corrosion coating.
Packaging and transportation: The qualified connecting rod is packaged and ensured that it is not damaged during transportation.
Through the in-depth discussion of the production process of locomotive main and auxiliary connecting rod forging, we can draw the following conclusions and suggestions:
Material selection: The selection of high-strength and high-toughness materials can improve the quality and service life of forgings. At the same time, considering the cost factor, reasonable selection of materials.
Forging process: Optimizing forging process parameters, such as heating temperature, forging times, etc., can improve the quality and production efficiency of forging parts. At the same time, pay attention to control the defects and deformation in the forging process.
Quality control: Establish a sound quality control system, strictly check every link, to ensure that each forging meets the requirements. Trace and deal with nonconforming products to avoid batch problems.
Technological innovation: pay attention to industry dynamics and technological development, and constantly introduce new technologies, new processes and new equipment to improve production efficiency and product quality. At the same time, we will strengthen investment in technology research and development and innovation to promote sustainable development of enterprises.
