The production of crane track shoes involves a series of carefully controlled steps to ensure the quality. Below is a detailed explanation of each stage in the production process:
01.Make Mold
Step: Design and create a mold based on the specifications of the crane track shoe.
Tools: CAD software, CNC machines, or manual mold-making tools.
Outcome: A precise mold that defines the shape and dimensions of the track shoe.
02.Sand Mold
Step: Prepare a sand mold by packing specially treated sand around the pattern (mold).
Purpose: To create a cavity in the shape of the track shoe for casting.
Outcome: A reusable mold ready for the casting process.
03.Casting
Step: Pour molten metal (typically alloy steel) into the sand mold to form the rough shape of the track shoe.
Outcome: A rough casting that matches the design specifications.
04.Polishing riser milling
Step: Remove excess material (such as risers and gates) from the casting and polish the surface to achieve the desired finish.
Tools: Grinding machines, milling equipment.
Outcome: A smoother surface and precise dimensions.
05.Quenching & Tenpering
Step: Heat the track shoe to a high temperature and then rapidly cool it (quenching) to increase hardness. Follow this with tempering to reduce brittleness and improve toughness. Outcome: Enhanced mechanical properties, including strength and wear resistance.
06.Machanical Properties Test
Step: Conduct tests such as tensile strength, impact resistance, and elongation to ensure the material meets required standards.
Outcome: Verified mechanical properties for optimal performance.
07.Surface Quenching
Step: Apply surface hardening techniques (e.g., induction hardening) to increase the hardness of the track shoe’s outer layer.
Outcome: A wear-resistant surface that extends the track shoe’s lifespan.
08.Hardness Test
Step: Measure the hardness of the track shoe using methods like Rockwell or Brinell testing. Outcome: Confirmation that the track shoe meets hardness specifications for durability and performance.
09.Painting
Step: Apply protective coatings (e.g., paint or anti-corrosion treatments) to prevent rust and enhance appearance.
Outcome: A finished track shoe with improved durability and a professional look.
10.Final Inspection
Step: Conduct a comprehensive quality check, including dimensional accuracy, surface finish, and performance tests.
Outcome: A high-quality track shoe ready for use.
11.Packing
Step: Securely package the track shoes to protect them during transportation.
Outcome: Ready-to-ship products that arrive in perfect condition.
