Abstract
The invention relates to a splined sleeve processing technology which comprises the following steps: 1), material preparing; 2), oxalate processing; 3), external spline extruding: drying processed blanks on a dryer, placing the blanks on a hydraulic machine after the blanks are cooled, and extruding the spline; 4), spheroidizing annealing: placing the blanks in an annealing furnace to be subjected to spheroidizing annealing; 5), shot blasting: placing the blanks on a crawler-type shot blasting machine to perform shot blasting; 6), oxalate processing; 7), internal spline extruding: placing processed blanks on a hydraulic machine to extrude the spline; 8), finish machining: placing the blanks on a numerically-controlled machine tool to perform finish machining; 9), cleaning: placing a finished product in a ultrasonic cleaner to clean. According to the invention, solid bars are adopted to perform the cold extrusion molding, so that raw material loss is reduced; besides, blank processing time is shortened as blanks are subjected to non-chip processing; the internal spline is subjected to solid cold extrusion molding; during the follow-up processing, the processing is easy and loss of cutters is reduced by virtue of the small working allowance, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of spline housing processing technology.
Background technology
The step that traditional spline housing processing technology adopts is normally: process-straight-through-tack of blanking-spheroidizing and one extruding-boring-finish turning endoporus-oxalates processing-spline two road extruding-fine finishining-cleaning of chamfering-oxalates processings-spline.Need to carry out machining in the traditional handicraft process, to the loss of process tool, process time is also longer during than Datong District.Therefore need a kind of novel processing technology to overcome the deficiency of traditional handicraft.
Summary of the invention
The object of the present invention is to provide a kind of spline housing processing technology of simultaneously enhancing productivity that reduces costs.
For achieving the above object, the present invention adopts following technical scheme: a kind of spline housing processing technology, and this technique comprises the following steps: 1) blanking: bar is placed on metal annular sawing machine and carries out blanking, require end face smooth;
2) oxalates is processed: blank is put into to the oxalates treatment fluid, during operation temperature be 70 degree to 90 degree, the reaction time is by corresponding long 10-20 minute;
3) external splines extruding: the blank of handling well is first dried on dryer, be placed on hydraulic press after waiting blank cooling and push spline;
4) spheroidizing is processed: blank is placed in annealing furnace and carries out spheroidizing;
5) Shot Blasting: blank is placed on to Caterpillar type shot blasting machine and carries out ball blast;
6) oxalates is processed: blank is put into to the oxalates treatment fluid, during operation temperature be 70 degree to 90 degree, the reaction time is by corresponding long 10-20 minute;
7) internal spline extruding: the blank of handling well is placed on hydraulic press and pushes spline;
8) fine finishining: blank is placed on to numerically controlled lathe and carries out fine finishining;
9) clean: finished product is put into to supersonic wave cleaning machine and cleaned.
Further, require surperficial non-scale in the annealing in process process, the decarburization phenomenon.
Further, need put into a certain proportion of diameter during Shot Blasting is the thin steel ball of 0.2mm, operating time 20-25 minute.
Further, scavenging period is about 5 minutes.
Compared with prior art, the present invention has following beneficial effect: the new technology spline adopts solid bar to carry out cold extrusion shaped and old technique and compares and saved raw-material loss, blank adopts the process time that has shortened blank without machining simultaneously, internal spline adopts solid cold extrusion shaped, in the following process process, the little easy processing of allowance has reduced the loss of cutter simultaneously, has improved production efficiency.
The accompanying drawing explanation
Fig. 1 is process chart of the present invention.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the invention will be further described.
Refer to shown in accompanying drawing, a kind of spline housing processing technology of the present invention, this technique comprises the following steps: 1) blanking: bar is placed on metal annular sawing machine and carries out blanking, require end face smooth; 2) oxalates is processed: blank is put into to the oxalates treatment fluid, during operation temperature be 70 degree to 90 degree, the reaction time is by corresponding long 10-20 minute;
3) external splines extruding: the blank of handling well is first dried on dryer, be placed on hydraulic press after waiting blank cooling and push spline; And be lubricated with salad oil;
4) spheroidizing is processed: blank is placed in annealing furnace and carries out spheroidizing;
5) Shot Blasting: blank is placed on to Caterpillar type shot blasting machine and carries out ball blast;
6) oxalates is processed: blank is put into to the oxalates treatment fluid, during operation temperature be 70 degree to 90 degree, the reaction time is by corresponding long 10-20 minute;
7) internal spline extruding: the blank of handling well is placed on hydraulic press and pushes spline; And be lubricated with salad oil
8) fine finishining: blank is placed on to numerically controlled lathe and carries out fine finishining;
9) clean: finished product is put into to supersonic wave cleaning machine and cleaned.
When described oxalates is processed, if newly-built bath the reaction time can shorter 10-15 minute, after tank liquor is aging, the reaction time, by the corresponding 15-20 minute that rises to, should be changed groove when there are a large amount of yellow green bits on surface.
Require surperficial non-scale in the annealing in process process, the decarburization phenomenon.
Need put into a certain proportion of diameter during Shot Blasting is the thin steel ball of 0.2mm, and operating time 20-25 minute removes surface scale and impurity.
Described scavenging period is about 5 minutes.
The present invention adopts solid bar to carry out cold extrusion shaped and old technique and compares and saved raw-material loss, blank adopts the process time that has shortened blank without machining simultaneously, internal spline adopts solid cold extrusion shaped, in the following process process, processing She measures the loss that little easy processing has reduced cutter simultaneously, has improved production efficiency.
