Abstract
The invention relates to a large-sized nonstandard sprocket dentiform part machining process, which belongs to the field of machinery manufacturing, in particular to a process of machining a large-sized nonstandard sprocket dentiform part at high yield. The process comprises the following concrete steps: firstly carrying out rough machining on a shape cutting machine, and then placing a roughly machined sprocket on a VMC-745 vertical machining centre workbench for finish machining. By adopting the process, the machining consumed time of the large-sized nonstandard sprocket dentiform part is shortened, the yield is increased and the labor power is saved.
Description
Technical field
A kind of large-scale non-standard sprocket tooth form position processing technology belongs to mechanical manufacturing field, is specially a kind of technology of the non-standard sprocket wheel of machining large of high yield.
Background technology
The toothed section of large-scale non-standard sprocket wheel be sprocket wheel most important also be the most unmanageable part, the technology at the non-standard sprocket tooth form of existing machining large position has following several: the one, and the contrast drawing, hole behind the circumference in equal parts, then with ordering ready-made flute profile cutter gear-shaping processing, once press from both sides 3～4, be difficult to finish processing a working day.The 2nd, directly to process with the numerical control machining center machine, the every workday also can only be produced one.The 3rd, according to the tailor-made good hobboing cutter of drawing requirement, on gear-hobbing machine, to process, produce one two working days.The 4th, to process with wire cutting machine, the every workday can be finished one.More than several processing technologys can both produce qualified sprocket tooth form position, but consuming time many, yield poorly.
Summary of the invention
The invention provides a kind of large-scale non-standard sprocket tooth form position processing technology, solved the shortcoming that existing several large-scale non-standard sprocket tooth forms position processing technology yields poorly.
Realize that the technical scheme that above-mentioned purpose of the present invention adopted is:
A kind of large-scale non-standard sprocket tooth form position processing technology, comprise following steps: make roughing copying template mould according to sprocket wheel, the copying template mould keeps 1.5～2 millimeters allowance, sprocket wheel sheet material is erected the back horizontal positioned, after installing copying template mould and cutting torch on the copying cutting machine, open oxygen cylinder and acetylene cylinder switch, cut sprocket wheel sheet material the igniting back, remove the chain wheel periphery after cutting finishes and cut slag, utilize the tooth portion edge of the milling cutter cutting sprocket wheel on the VMC-745 vertical machining centre then, finish toothed section processing.
The allowance of copying template mould design is 2 millimeters.
Speed during the copying cutting machine cutting is 320 millimeters/minute, during the cutting chain wheel sheet material of igniting back, looks the situation of cutting, and adjusts the ratio of oxygen and acetylene, makes slot narrow, sliding, and the roughness of cut surface is controlled between 12.5～6.3.
The VMC-745 vertical machining centre is adding man-hour to sprocket wheel sheet material, and allowance is less than 2 millimeters.
The present invention produces sprocket wheel in batches, and the time spent is few, output is high, produces a qualified sprocket wheel and only needs 60～70 minutes, and can produce 7-8 spare a working day, improved production efficiency greatly.
The specific embodiment
Below in conjunction with specific embodiments of the invention the present invention is described in detail.
Processing a kind of diameter is the sprocket tooth form position of 430mm, thick 22mm, at first according to the size of drawing, carries out the copying template mould, the size of copying template mould and sprocket wheel consistent size, and keep 2mm allowance.Liftoff 50 millimeter of the sprocket wheel sheet material that will process are erected, with firm placement the in balance chi smoothing back, then copying cutting machine is placed on outside the sprocket wheel sheet material zone that to cut, after installing 0# cutting torch and former plate mould, open the switch of oxygen cylinder and acetylene cylinder respectively, oxygen pressure is adjusted to 0.30MPa, the pressure of acetylene is greater than 0.03MPa, and igniting is cuts sheet material afterwards, cutting speed 320mm/ branch, according to the situation of cutting, adjust the ratio of oxygen and acetylene, make slot narrow, sliding, the roughness of cut surface is controlled between 12.5～6.3, after cutting finishes, knock out the chain wheel periphery and cut slag preparation carrying out fine finishining.
The good sprocket wheel of roughing is placed on the workbench of VMC-745 vertical machining centre, two holes of Φ 20mm have been bored in sprocket wheel center of circle part, wearing two Φ 18mm screws is connected with the silk seat, sprocket wheel is fixed, after finding the center of sprocket wheel accurately, milling cutter on the VMC-745 vertical machining centre is processed cutting according to instruction to the sprocket wheel edge, finishes toothed section processing, and the machined surface roughness is 3.2.
In the present embodiment, process a sprocket tooth form position that diameter is 430mm, thick 22mm, adopt imitative sprocket wheel of type cutting machine roughing, specifically decompose as follows: 1. transferred oxygen, acetylene pressure 1 minute
2. adjust cutting position 2.5 minutes
3. cutting processing is 4.5 minutes
4. remove the workpiece slag 5 minutes, add up to 13 minutes times spent.
With VMC-745 vertical machining centre fine finishining sprocket tooth form position, decompose as follows:
1. adorned, press from both sides, unload 5 minutes
2. alignment, processing 45 minutes add up to 50 minutes.
After adopting the present invention, on average processed a sprocket wheel 63 minutes consuming time, according to calculating at 8 hours on a working day, the average every workday can be processed 7～8 sprocket wheels, and its output has substantially exceeded existing processing technology, and saves manpower.
