Description
Technical field
The present invention relates to field of machining, and in particular to large aluminium-board rolling-mill housing processing method.
Technical background
In recent years, the demand of China's wide cut aluminium sheet and aluminium foil product is increasing, and quality requirement is also higher and higher, and aluminium adds
Work enterprise starts one after another receives high Precision Aluminium plate mill and aluminium foil mill greatly to seize market, and the rib heart technology of large-scale aluminium foil mill
Substantially rest in overseas-funded enterprise's hand, domestic large-sized rolling mills are not also very ripe.Foreign capitals enterprise hall for save cost, start by-
A little non-rib center portion parts transfer to domestic enterprise to manufacture.Such as milling train frame, it is difficult in process processing, and machining accuracy cannot
It is guaranteed very well.
The content of the invention
To solve the above-mentioned problems, a kind of process of present invention offer is simple, can guarantee that the machining accuracy of workpiece, reduces
Production cost, improves the large aluminium-board rolling-mill housing processing method of production efficiency.
Large aluminium-board rolling-mill housing processing method of the present invention, comprises the following steps：
The first step, line：The effect of line mainly checks whether blank is qualified, if there is casting deformation, situations such as misrun,
It is required that crossed process redistributes the processing capacity in each face in the case where ensureing that each face can process, namely what is often called
By means of processing capacity, strictly according to the facts by means of not getting up, need to be remedied by being heat-treated the method for correction or soldering；
Second step, roughing, removes unnecessary processing capacity according to line on the relatively low milling shuttlecock bed of ratio of precision, is follow-up to greatest extent
Finishing is prepared, and rough milling can save process time with big cutting speed or feed speed, and final roughness reaches
More than row spinulose tree fern, each machined surface stays allowance 10mm-12mm, and defect detecting test is carried out after the completion of process；
3rd step, process of detecting a flaw and processing defect, after roughing, the crackle in shift report face, gas are sent out using the method for dyeing inspection
The defects of hole, sand holes, the defects of internal contracting is taken turns, product grain is thick is checked with ultrasonic examination, for casting crystalline grain gross defects
The method for being heat-treated normalizing again must be used to remove, other defect carries out soldering processing after being cleaned out with lathe；
4th step, semifinishing, the higher milling-boring machine of precision remove most allowance, and to being produced after defect processing
The deformation deviation row that spouts is corrected, and first with big cutting speed or feed velocity rapid processing during processing, last knife bite is small, and
And pressing plate is first unclamped before processing, machining stress is discharged, then compress, ensure each polished surface allowance uniformly and after processing
Dimensional stability, single side allowance 0.5mm；
5th step, finishing, finishes and is processed on CNC planer type milling machine or cnc boring and milling machine, is carried out using numerical control programming automatic
Processing, and be lubricated and cool down using cutting fluid, it is ensured that high surface smoothness and dimensional accuracy.
Process of the present invention is simple, can guarantee that the machining accuracy of workpiece, reduces production cost, improves production efficiency.
Embodiment
Large aluminium-board rolling-mill housing processing method of the present invention, comprises the following steps：
The first step, line：The effect of line mainly checks whether blank is qualified, if there is casting deformation, situations such as misrun,
It is required that crossed process redistributes the processing capacity in each face in the case where ensureing that each face can process, namely what is often called
By means of processing capacity, strictly according to the facts by means of not getting up, need to be remedied by being heat-treated the method for correction or soldering；
Second step, roughing, removes unnecessary processing capacity according to line on the relatively low milling shuttlecock bed of ratio of precision, is follow-up to greatest extent
Finishing is prepared, and rough milling can save process time with big cutting speed or feed speed, and final roughness reaches
More than row spinulose tree fern, each machined surface stays allowance 10mm-12mm, and defect detecting test is carried out after the completion of process；
3rd step, process of detecting a flaw and processing defect, after roughing, the crackle in shift report face, gas are sent out using the method for dyeing inspection
The defects of hole, sand holes, the defects of internal contracting is taken turns, product grain is thick is checked with ultrasonic examination, for casting crystalline grain gross defects
The method for being heat-treated normalizing again must be used to remove, other defect carries out soldering processing after being cleaned out with lathe；
4th step, semifinishing, the higher milling-boring machine of precision remove most allowance, and to being produced after defect processing
The deformation deviation row that spouts is corrected, and first with big cutting speed or feed velocity rapid processing during processing, last knife bite is small, and
And pressing plate is first unclamped before processing, machining stress is discharged, then compress, ensure each polished surface allowance uniformly and after processing
Dimensional stability, single side allowance 0.5mm；
5th step, finishing, finishes and is processed on CNC planer type milling machine or cnc boring and milling machine, is carried out using numerical control programming automatic
Processing, and be lubricated and cool down using cutting fluid, it is ensured that high surface smoothness and dimensional accuracy.
The friction asked of the effect of cutting fluid mainly cutting, workpiece and cutter, reduces cutting force and cutting temperature, reduces
Workpiece thermal deformation and tool wear, improve cutter life, Workpiece Machining Accuracy, improve processed surface smoothness.In adding for rack
During work, generally cutting fluid is not had to during roughing work, impurity is too many in cutting when being mainly roughing, and easily pollution is cut
Liquid, and assisted machining effect unobvious are cut, the comparison generally in semifinishing and finishing step is more, sometimes for clear
Clean production, without cutting fluid, the stage is protection cutter, improves processing efficiency, ensures last machining accuracy half finishing fourth, is led to
Often need to use cutting fluid, when selecting cutting fluid, mainly the cooling of consideration cutting fluid, lubrication, cleaning, antirust integrate energy
Power, cost performance, whether environmental protection, safeguard replace whether the factor such as convenient.
