Abstract
It is high in order to solve the cost having in the prior art using the method that electric pulse technique carries out processing guide groove to the axle sleeve produced, and the problem that production efficiency is very low, the present invention provides a kind of processing method of axle sleeve with guide groove, the following steps are included: step 1, raw material powder is suppressed by axle sleeve using mold at the beginning of base, with the protrusion being adapted to keyway to be processed on mold, the corresponding keyway in position is had on the inner hole of the first base of obtained axle sleeve；Step 2, the grinding that inner hole, outer circle are carried out after firing blank；The guide groove of step 3, processing connection keyway.Axle sleeve keyway and guide groove are produced using aforesaid way, reduce previous deep processing electric pulse process, the critical size control that technique processing proposes is met by such method and is required, and is high in machining efficiency, especially suitable for batch machining.
Description
Technical field
The invention belongs to field of machining, are related to a kind of processing method of axle sleeve with guide groove.
Background technique
In order to meet requirement, need to process the hard alloy axle sleeve with inner hole key slot.To answer extensively
For hard alloy axle sleeve for operations such as oil-immersed pump processing, setting and the consistent guide groove of inner hole extending direction in axle sleeve,
The size of guide groove is adapted to the key on workpiece, strong along axle sleeve on workpiece when use during workpiece insertion axle sleeve
Guide groove sliding, by the cooperation of key and guide groove, workpiece will not be circumferentially rotated relative to axle sleeve, and key and axle sleeve for convenience
The assembly of guide groove, sharp edge defect when reducing assembly and operating need that opening is arranged slightly larger than guide groove at guide groove both ends
Keyway, the guide groove high for hard alloy axle sleeve guide groove and keyway, especially required precision and keyway, it usually needs use
Electric pulse technique processes the axle sleeve produced, and electric machining mode cost is high, accounts for entirely finishing in cost
70% or more, and production efficiency is very low, every equipment daily output is difficult to meet user's bulk article delivery date need less than 30
It asks.
Summary of the invention
Based on problem above, the purpose of the present invention is to provide a kind of sides of sleeve product of the quickly production with guide groove
Method promotes processing efficiency by the processing method, especially suitable for batch machining, and can guarantee machining accuracy, processing method letter
It is single.
To achieve the goals above, a kind of the technical solution adopted by the present invention are as follows: processing side of the axle sleeve with guide groove
Method, comprising the following steps:
Step 1, raw material powder is suppressed by axle sleeve using mold at the beginning of base, with being adapted to keyway to be processed on mold
Protrusion has the corresponding keyway in position on the inner hole of base at the beginning of obtained axle sleeve；
Step 2, the grinding that inner hole, outer circle are carried out after firing blank；
The guide groove of step 3, processing connection keyway.
The processing method of axle sleeve provided by the invention with guide groove, since the required precision of keyway is lower, first
Base at the beginning of raw material powder is suppressed into the axle sleeve with keyway using mold, then the accurate processing of guide groove is carried out, guide groove
The method of wire cutting can be used to realize in processing, in this way, just not having to first process axle sleeve, then processes guide groove by electric pulse technique
With keyway, processing cost can reduce 40% or more.
The raw material powder used in the step 1 is cemented carbide powder.
Further, method provided by the invention is suitable for the axle sleeve that processing dimension is small, required precision is high, axle sleeve to be processed
Hole size be 32mm or less；The depth of guide groove to be processed is 1.1mm hereinafter, width is 1.7mm or less；Keyway to be processed
For vertebra shape.
The beneficial effects of the present invention are: there is higher processing efficiency, especially suitable for batch machining, and can guarantee processing
Precision, processing method are simple.
Detailed description of the invention
Fig. 1,2 are that the obtained axle sleeve blank schematic diagram with keyway is processed in step 1；
Fig. 3 is the schematic diagram of the axle sleeve finished product processed；
Wherein, 1 is keyway, and 2 be guide groove.
Specific embodiment
Below in conjunction with attached drawing, the invention will be further described with embodiment:
Embodiment
The present embodiment provides hard alloy axle sleeve guide groove production method for producing hard alloy axle sleeve guide groove
Detailed explanation.
The requirement of the axle sleeve to be processed of the present embodiment are as follows: inner hole 30.2+ (0~0.5) mm, the groove depth of guide groove 2 are 0.8+
(0~0.356) mm, 1 width of keyway are 1.626+ (0~0.025) mm, 2.55 ± 0.32mmx5.08 of flute profile ± 1.27mm,.
The processing method used in the present embodiment forms for blank guarantees 2 shape of guide groove, a kind of axis with guide groove 2
The processing method of set, which comprises the following steps:
Step 1, raw material powder is suppressed by axle sleeve using mold at the beginning of base, with being adapted to keyway 1 to be processed on mold
Protrusion, obtained axle sleeve just base inner hole on have the corresponding keyway 1 in position, as shown in Figure 1, 2；
Step 2, the grinding that inner hole, outer circle are carried out after firing blank；
The guide groove 2 of step 3, linear cutter connection keyway 1, as shown in Figure 3.
Using the guide groove 2 of above-mentioned measurement method production 1 position of hard alloy axle sleeve keyway, previous deep processing electricity arteries and veins is reduced
Process is rushed, the critical size control that technique processing proposes is met by such method and is required.
Although the present embodiment is for processing hard alloy sleeve product, to the guide groove production measurement method of above-mentioned axle sleeve
It is illustrated, but the guiding groove processing method of above-mentioned axle sleeve is not limited to processing hard alloy axle sleeve, can be adapted for adding
The guide groove of work other materials.
