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 lifeof 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 1/3of 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 enhancesthe production efficiency.
Description
Technical field
The present invention relates to a kind of manufacture method that is applicable to the heavy type mining gipsy sheave of drag conveyor, elevating conveyor.
Background technology
Sprocket wheel also is a consumable accessory as the main parts size of drag conveyor, elevating conveyor, and consumption is very big.Traditional sprocket wheel adopts two kinds of manufacturing process usually, and a kind of is that Electrolyzed Processing becomes profile of tooth, and another kind is the machining profile of tooth, and its manufacturing process is as follows respectively:
1, simply connected sprocket wheel blank is forged in blanking; The roughing after-baking is modified; Be welded into whole sprocket wheel; Half finish turning endoporus; Electrolyzed Processing becomes profile of tooth, chain nest; Chain nest quenching heat treatment; Be finish-machined to the size of drawing requirement; So just finished the manufacturing of sprocket wheel.
2, simply connected sprocket wheel blank is forged in blanking; The roughing blank; Be welded into whole sprocket wheel behind copy milling processing profile of tooth and the chain nest; Heat treatment quenching and tempering, chain nest quench; Partly smart, as to be finish-machined to drawing requirement size; Finish the manufacturing of sprocket wheel.
Mining gipsy sheave adopts Electrolyzed Processing and copy milling processing technology to have the following disadvantages:
When 1, sprocket wheel adopted Electrolyzed Processing profile of tooth, chain nest, profile of tooth calibration inequality, chain nest that electrolysis goes out varied, and error is very big, causes the workpiece amount of reprocessing big, influences product quality.
2, sprocket wheel employing Electrolyzed Processing and copy milling are processed profile of tooth, chain nest production efficiency is very low.With ￠ 30mm double center chain wheel (three strand wheels are formed), adopt electrolytic processing process to produce a cover sprocket wheel 140 hours consuming time, adopt the copy milling processing technology to produce a cover sprocket wheel 161 hours consuming time.
3, the power consumption of electrolysis sprocket wheel is very high.
4, Electrolyzed Processing and copy milling processing sprocket wheel man-hours requirement is more, the manufacturing cost height.
Summary of the invention
The purpose of this invention is to provide a kind of dependable performance, make the manufacture method of heavy type mining gipsy sheave easy, energy-conservation, with low cost.
For achieving the above object, the technical solution used in the present invention is:
A kind of manufacture method of heavy type mining gipsy sheave, its special feature is, comprises the following steps, forging stock roughing is heated to material base 300-450 ℃ then, material base is hung in the shape cutting tire again, mandrel location, centering, pressing plate compresses, the moulding of profiling gas cutting.
Wherein for duplicate sprocket, also need turn over again once, mandrel location, centering, pressing plate compresses, the moulding of profiling gas cutting.
Forging stock roughing goes out to go up lower plane, technology endoporus, grooving, and mark the cross centre line at endoporus two ends, then the roughing material base is heated to 300-450 ℃ in car type furnace, to heat the material base overhead traveling crane again hangs on the copying cutting machine cutting tire, mandrel is located, is pressed copying template centering groove and line centering with the centering mouth, pressing plate compresses, the moulding of profiling gas cutting.
Further, wherein for duplicate sprocket, need turn over once again, the mandrel location, press copying template centering groove and the centering of ruling with the centering mouth, pressing plate compresses, the moulding of profiling gas cutting.
For the odd number tooth sprocket, on copying template, increase the centering plate of a trough of belt, mandrel is located, is pressed copying template centering groove, centering plate and line centering with the centering mouth, and pressing plate compresses, the moulding of profiling gas cutting.
Further, wherein for duplex odd number tooth sprocket, need turn over once the individual centering plate that increases a trough of belt on copying template again, mandrel is located, is pressed copying template centering groove, centering plate and line centering with the centering mouth, and pressing plate compresses, the moulding of profiling gas cutting.
The roughing material base is heated to 350 ℃.
Adopt profiling of the present invention not have surplus cutting teeth shape technology and have following technique effect:
1, the heavy type mining gipsy sheave of external exploitation at present is mainly based on Numerical control cutting profile of tooth or machining profile of tooth, and the mining heavy sprocket wheel that the applicant produces is to adopt profiling not have surplus cutting teeth shape technology mode, guaranteed the accuracy of manufacture of sprocket wheel, help improving its service life, reach advanced world standards.
2, energy-saving effect is remarkable, and the power consumption of shape cutting sprocket wheel only is 1/3 of an electrolysis sprocket wheel.
3, be 3 times of shape cutting sprocket wheel the man-hour of electrolysis sprocket wheel, and be 3.5 times of shape cutting sprocket wheel the man-hour of copy milling processing sprocket wheel, and obviously the shape cutting sprocket wheel had both reduced manufacturing cost, had also improved production efficiency simultaneously greatly.
The specific embodiment
The present invention is further detailed explanation below in conjunction with specific embodiment:
Embodiment 1:
Forging stock roughing goes out to go up lower plane, technology endoporus, grooving, and marks the cross centre line at endoporus two ends; The roughing material base is heated to 350 ℃ in 75 type car type furnaces, will heats the material base overhead traveling crane again and hang on the copying cutting machine cutting tire; Press the correct selection of drawing technology and centering copying template, horizontal error≤1.5mm are installed; Correctly select the cutting torch number by cutting thickness and technological requirement, centering burning torch perpendicularity＜0.5mm; Copying template centering groove and line centering workpiece, error≤0.5mm are pressed with the centering mouth in the mandrel location; Pressing plate compresses, the moulding of profiling gas cutting.For duplicate sprocket, need turn over again once, the mandrel location, with the centering mouth press copying template centering groove and the centering workpiece of ruling two-sided, error≤0.5mm; Compress the moulding of profiling gas cutting.
The duplicate sprocket cut quality such as the following table that make: the mm of unit
All the other sprocket wheels can be made positioning core axle, copying template, centering model again according to design size and technological requirement and repeat above-mentioned steps and make.
