In the production process of locomotive main and auxiliary link forging, in order to ensure product quality and production efficiency, it is necessary to use a series of special equipment and tools. These equipment and tools are essential for forging forming, processing and testing. This paper will introduce the main equipment and tools needed to produce the forging of the main and auxiliary connecting rod of the locomotive.
Forging equipment
Free forging hammer: used for the initial forging of raw materials to make it close to the final shape. The tonnage of the free forging hammer depends on the size and requirements of the forging.
Die forging hammer: The die forging hammer is used to precisely form the metal in the die to form the connecting rod shape that meets the design requirements. The impact force of the forging hammer causes the metal to flow within the mold and fill various parts of the mold.
Heat treatment furnace: Used to heat and cool the forged connecting rod to achieve the required mechanical properties and microstructure. Heat treatment furnaces can be oil, gas or electric, depending on production needs.
Processing equipment
Milling machine: Used for roughing and finishing connecting rods to remove excess metal and achieve the required dimensional accuracy. Milling machines are usually equipped with different types of tools to adapt to different processing needs.
Grinder: Used for precision grinding of connecting rods to achieve high precision dimensions and surface quality. The grinding machine has a high precision spindle and guide rail system, which can achieve micron machining accuracy.
Drill press: Used to drill holes in connecting rods to meet bolting and other assembly requirements. The drilling machine has stable drilling accuracy and efficient production capacity.
Testing equipment and tools
Measuring tools: including calipers, micrometers, altimeters, etc., used to accurately measure the size of the connecting rod to ensure that it meets the design requirements.
Non-destructive testing equipment: such as ultrasonic detector, magnetic powder detector, etc., used to detect the internal defects and surface cracks of the connecting rod to ensure product quality.
Hardness tester: Used to test the hardness of the connecting rod to ensure that it meets the material requirements and process standards. The hardness tester can be of different types such as Rockwell, Brinell or Vickers hardness tester.
Mechanical properties testing machine: used to test the tensile, compression, bending and other mechanical properties of the connecting rod to ensure that it meets the working requirements of the engine. The mechanical property testing machine can be tested at room temperature or high temperature to simulate the actual working conditions.
Flaw detection equipment: such as eddy current detector, fluorescent penetration detector, etc., used for the detection of surface and near-surface defects of connecting rods. These inspection equipment can efficiently detect small defects and problems, improve the level of product quality control.
Environmental test equipment: In order to simulate various environmental factors under actual working conditions, such as temperature, humidity, salt spray, etc., it is necessary to use the corresponding environmental test equipment. These devices can test the performance and adaptability of connecting rods under different environmental conditions.
Auxiliary tools and equipment
Lifting equipment: used to lift the forged connecting rod from the production line to the designated location or for further processing. Commonly used lifting equipment includes crane, crane and so on.
Handling tools: such as forklifts, trucks, etc., used to transfer and move connecting rods and other materials between each process in the production process. These tools improve production efficiency and material handling accuracy.
Cleaning equipment: including cleaning machine, spray gun, etc., used to clean the connecting rod, remove oil, residue and other impurities. Cleaning equipment is of great significance to ensure the surface quality of products and extend the service life of products.
Packaging equipment: Used to pack the finished connecting rod to protect the product from damage and contamination. Packaging equipment can include automatic packaging machines, sealing machines, etc., to improve production efficiency and packaging consistency.
Safety protection equipment: In order to ensure the safe operation of the production process and maintain the health of employees, safety protection equipment such as goggles, gloves, earplugs, etc., need to be used. These devices reduce the risk of work-related injuries and occupational diseases.
To sum up, the production of locomotive main and auxiliary connecting rod forging requires the support of a series of professional equipment and tools. Through proper configuration and use of these devices and tools, production efficiency, product quality, and safety can be improved to meet market demand and enhance enterprise competitiveness.
