Method for manufacturing land leveler blade

Abstract

The invention relates to a method for producing scraper of leveler, wherein it comprises: (1) smelting abrasion resistant steel in the steelsmelting furnace, and irrigating the steel water into the steel module; (2) the casting machine casts the steel module, to cool and shape the steel water stepped, to avoid loose and foam; (3) using transmitter to transmit the work piece to another device, fixing work piece, and punching the mounting hole, and cooling it naturally in the device; (4) when the work piece is cooled to anneal temperature, thermally treating the work piece, to improve the surface rigidity and internal flexibility; (5) when the work piece is cooled to the solidify temperature, transmitting it to the check area, and cooling it to the room temperature and finishing, storing. The invention can confirm the quality of scraper, simplify the process, and reduce the producing cost.

Description

technical field [0001] The invention relates to a new manufacturing process of a scraper for a grader, to be more precise, relates to a method for processing and manufacturing a scraper, a major component of construction machinery—a grader, and belongs to the technical field of mechanical processing and forming of metal products. Background technique [0002] A grader is a road construction machine that mainly uses a scraper and is equipped with various other replaceable operating devices to perform land leveling and shaping operations. As a multi-purpose continuous operation earth-moving machine, the scraper (also known as the blade) of the motor grader is its most important accessory and wearable part. In highway construction, by continuously changing the plane angle and inclination angle of the scraper, or extending the scraper to any side, the grader can complete the following various land leveling and shaping operations: subgrade base treatment, turf or land surface Ta...

AI Technical Summary

Problems solved by technology

[0007] There are obvious deficiencies in the above-mentioned three kinds of prior art, which are specifically manifested as: the first prior art has many processes, and requires two heat treatments, which is labor-intensive and time-consuming, and the processing cost is high

Although the second production process has a lower processing cost, because of the low dimensional accuracy of sand casting and large quenching deformation, the dimensional tolerance and straightness of the scraper cannot be reliably guaranteed, and its products cannot be used for fine smoothing.

Although the third existing technology can guarantee the dimensional tolerance and straightness of the scraper, the cost of materials and spraying of wear-resistant hard alloy is very high, which makes the production cost expensive and affects its market share.
