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.

Embodiment Construction
[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0035] Referring to Fig. 4, introduce the processing method that the present invention manufactures grader scraper, comprise following operation:
[0036] (1) The wear-resistant steel is smelted in the steelmaking furnace, and the molten steel is poured into the steel mold of the die-casting equipment.
[0037] (2) The die-casting equipment pressurizes the steel mold for pressure casting, so that the molten steel is slowly cooled and formed in the steel mold to reach the outer contour of the finished scraper, and the material is dense to avoid looseness and air bubbles.
[0038] (3) The workpiece is transported to another device via the transfer device, and after the workpiece is fixed, each mounting hole is hot-stamped and cooled naturally in the device at the same...

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 precise, to a method for processing and manufacturing a scraper, a main 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 Take soil from b...
