Abstract

The invention belongs to the technical field of waste steel rail treatment, discloses a machining method for manufacturing a loading machine cutting board through waste steel rails, and aims to solve the problem that the waste steel rails cannot be directly used as the loading machine cutting board. The method comprises the following steps: (1) cutting the waste steel rail by adopting flame cutting to form a semi-finished product of the cutting board of the loading machine; the flame cutting comprises a first cutting, a second cutting and a third cutting, and a semi-finished product of the cutting board of the loading machine is formed after the first cutting, the second cutting and the third cutting; and (2) carrying out surface quenching treatment and low-temperature tempering treatment on the blade part at the front end of the semi-finished product of the loader cutting board to obtain the loader cutting board. According to the method, the value of the waste steel rail can be utilized to the maximum extent, meanwhile, part of the cast cutting board can be replaced, energy and resources used for casting are saved, and the replacement cost of the loader cutting board is reduced.

Description

technical field [0001] The invention belongs to the technical field of waste steel rail processing, and in particular relates to a processing method for making loader blades by using waste steel rails, which is used for recycling waste steel rails to achieve full utilization of resources. Background technique [0002] As of 2020, my country's loader market has about 1.4 million units, and the mining and infrastructure construction industries account for about 65% of the total, which is about 910,000 units. In these two industries, loaders are used more frequently and their accessories are more worn. Big. Under normal working conditions, the blades of buckets need to be replaced once a year on average. For harsh working conditions such as concrete mixing plants and mining, the blades need to be replaced more frequently. In addition to the hardness and strength indicators, the blade also has certain requirements for impact toughness. Under normal working conditions, the surfac...
