Method for manufacturing heavy type mining gipsy sheave

Abstract

The invention relates to a method for manufacturing a heavy mineral sprocket that is suitable for a scraper conveyor and a transfer machine, which is characterized in that: the method comprises the following steps that: a rough machining is applied to a forging blank, the forging blank is heated to the temperature ranging from 300 DEG C to 450 DEG C and then a material blank is lifted into a profiling cutting bracket; a core shaft is positioned and aligned, and a pressure plate is compressed tightly and subject to the profiling air cutting formation. The invention has the following technical advantages that: 1. by adopting the profiling allowance-free cutting tooth-shaped process, the manufacturing precision of the sprocket is ensured, so as to be beneficial to prolonging the service life of the sprocket and the achieving the internationally advanced level; 2. the effect of energy saving is distinctive, and the energy consumption of the profiling cutting sprocket only accounts for 1 / 3 of that of the electrolytic sprocket; 3. the working hours of the electrolytic sprocket account for 3 times of the that of the profiling cutting sprocket and the working hours of the profiling milling processing sprocket only account for 3.5 times of that of the profiling cutting sprocket. Obviously, the profiling cutting sprocket not only reduces the manufacturing cost, but also greatly enhances the production efficiency.

Description

technical field [0001] The invention relates to a manufacturing method of a heavy-duty mining sprocket suitable for scraper conveyors and loaders. Background technique [0002] As the main parts of scraper conveyors and reloaders, sprockets are also vulnerable parts, and the consumption is very large. Traditional sprockets usually use two manufacturing processes, one is electrolytic machining into tooth shape, and the other is machining tooth shape. The manufacturing processes are as follows: [0003] 1. Blank forging into single sprocket blank; heat treatment and tempering after rough machining; welding into integral sprocket; semi-finishing inner hole; electrolytic processing into tooth shape and chain pocket; chain pocket quenching heat treatment; finishing into drawing requirements dimensions; this completes the manufacture of the sprocket. [0004] 2. Cutting and forging into a single chain sprocket blank; rough machining the blank; profiling and milling the tooth pro...

AI Technical Summary

Problems solved by technology

[0006] 1. When the sprocket adopts electrolytic machining of the tooth shape and the chain socket, the electrolytic tooth shape is uneven, the chain socket is large and small, and the error is large, resulting in a large amount of workpiece repairs and affecting product quality.

[0007] 2. The sprocket adopts electrolytic machining and profiling milling to process the tooth shape, and the production efficiency of the chain socket is very low

[0008] 3. The energy consumption of the electrolytic sprocket is very high

[0009] 4. Electrolytic machining and profiling milling sprockets require more man-hours and high manufacturing costs
