Die is an important tool in the forging process of locomotive track seat, its design and manufacturing quality directly affect the quality of forging, production efficiency and manufacturing cost. This paper will discuss the mold design and manufacture of locomotive track seat forgings to help readers better understand this field.
Die design is a key link in the forging process of locomotive track seat, which determines the shape, size and surface quality of the forging. In the mold design, the following points need to be fully considered:
Drawing digestion: Carefully read the design drawings and fully understand the requirements on the drawings, including the shape, size and tolerance of the forgings.
Material selection: According to the material characteristics of the forging, production batch and production environment and other factors, choose the appropriate mold material. Commonly used mold materials are steel, carbide and so on.
Structure design: According to the drawing requirements and production requirements, design a reasonable mold structure. The mold structure should be as simple and compact as possible to facilitate processing and maintenance.
Heat treatment and surface treatment: According to the nature of the mold material, determine a reasonable heat treatment and surface treatment process to improve the hardness and wear resistance of the mold.
After the completion of the mold design, it is necessary to use the appropriate manufacturing process to produce the mold. The following are some commonly used mold manufacturing processes:
Roughing: Remove most of the margin of the mold blank to provide the basis for subsequent processing. Common roughing processes are milling, planing and so on.
Finishing: Through grinding, grinding and other methods, the mold is accurately processed to meet the accuracy requirements of the design drawings.
Electromachining: The use of electric discharge, wire cutting and other electrical machining methods to process the mold efficiently. These methods are suitable for molds with complex shapes and high precision requirements.
Heat treatment and surface treatment: According to the design requirements, heat treatment and surface treatment of the mold to improve its hardness and wear resistance.
Testing and acceptance: testing and acceptance of the finished mold to ensure that it meets the design requirements. Test content should include shape, size, surface quality, etc.
In order to extend the service life of the mold and improve production efficiency, it is necessary to carry out regular maintenance and maintenance of the mold. Here are some common care and maintenance measures:
Cleaning: Regularly remove oil, rust and other impurities on the surface of the mold to keep the mold clean.
Check and adjust: regularly check whether all parts of the mold are working normally, such as the mold cavity, positioning device, etc. If there is an anomaly, timely adjustment or maintenance.
Lubrication: Periodically apply lubricant to the sliding part of the mold to reduce friction and wear.
Storage: Store the mold in a dry, dust-free place to avoid moisture and rust.
Record and report: Record every maintenance and maintenance, and report abnormal conditions or failures in time for timely treatment and prevention.
To sum up, the mold design and manufacturing of locomotive track block forging is a complex process, which requires comprehensive consideration of design, materials, technology and maintenance. Through reasonable mold design and manufacturing process, as well as correct maintenance and maintenance measures, can ensure the normal use of the mold and extend its service life, so as to improve the production efficiency and product quality of locomotive track block forging.
