Problems solved by technology

[0002] Excavator bucket teeth currently available in the market are all precision casting products. After anatomical tests and metallographic tests, there are defects such as coarse grains, uneven distribution of chemical components, looseness, and pores.
As a result, the bucket teeth are often broken, vulnerable, and unable to achieve impact resistance and wear resistance during work, which is related to my country's traditional manufacturing process

Embodiment Construction

[0006] This specific embodiment adopts the following manufacturing process: 1. Alloy structural steel is selected, and steel materials of different specifications are selected for bucket teeth of different specifications, and the band saw machine cuts off the material; 2. The intermediate frequency furnace is heated to 1100 °C; 3. The head of the steel is set aside 30MM, and the 400KG air hammer rough forging T-shaped; 4. 100MM of the tooth tip is roughly formed by a 300T press; 5. No. 1 80T punch cuts the forging part and repairs the flash; It should be light, so that there is a 50MM pit in the middle of the workpiece, put appropriate coal particles in the pit, the purpose is to facilitate the punch to be pulled out from the workpiece, and then fully press the maximum energy of the 1000T press, and the workpiece is already Forming in the lower mold, the workpiece is ejected by the ejector device; 7. No. 2 80T punch press cuts the edge; 8. No. 3 80T punch punches the sub-hole; ...

Abstract

The invention provides a process for manufacturing excavator bucket teeth and relates to the technical field of excavator part manufacturing. The manufacturing process comprises a first step of selecting a material, a second step of heating to 1100 DEG C, a third step of performing rough forging T type through an air hammer, a fourth step of performing coarse crushing forming through a pressing machine, a fifth step of maintaining flash, a sixth step of performing stamping in a forming die, a seventh step of cutting edges, an eighth step of punching sub-holes, a ninth step of performing punching to punch marks, a tenth step of performing inner square hole shaping, an eleventh step of performing heat insulation and cooling, a twelfth step of performing detection to detect flaws, a thirteenth step of performing heat treatment and quenching, a fourteenth step of performing shot blasting and cleaning the surface, a fifteenth step of painting and a sixteenth step of packaging and placing the excavator bucket teeth in a warehouse. Crystals are thinned and uniform through forging and rearranging combination, pearlite and ferrite are evenly distributed according to internal metallographic structure analysis, and the excavator bucket teeth greatly improve mechanical performances and are high in strength and resistant to abrasion and impact.

Description

Technical field: [0001] The invention relates to the technical field of excavator parts manufacturing, in particular to a manufacturing process of excavator bucket teeth. Background technique: [0002] Excavator bucket teeth currently available in the market are all precision casting products. After dissection and metallographic tests, there are defects such as coarse grains, uneven distribution of chemical components, looseness, and pores. As a result, the bucket teeth are often broken, vulnerable, and fail to achieve impact resistance and wear resistance during work, which is related to my country's traditional manufacturing process. Invention content: [0003] The purpose of the present invention is to provide a manufacturing process for excavator bucket teeth, which makes the crystals more refined and uniform by forging and rearranging the combination, and the distribution of pearlite and ferrite is evenly analyzed from the internal metallographic structure, which grea...
