Abstract

The invention discloses a method for machining a regulating ring part. The method particularly includes 1), material preparation; 2), machining by lathe operators for roughly lathing the outer form of a workpiece and lengthening end sides of uniformly distributed annular surfaces on the circumferential surface of the workpiece to certain quantities; 3), heat treatment; 4) sand blowing; 5) machining by the lathe operators for finely lathing the inner form and the outer form of the workpiece and finely lathing molded surfaces, except for molded surfaces on the basis of the end sides of the uniformly distributed annular surfaces on the circumferential surface of the workpiece, until dimensions of the lathed molded surfaces meet requirements; 6), machining by borers for clamping lengthened portions of the workpiece and completely boring n holes by boring tools with corresponding sizes; 7), machining by the lathe operators for removing redundant portions of the workpiece according to depths of the annular surfaces and finely lathing the molded surfaces on the basis of the end sides of the uniformly distributed annular surfaces on the circumferential surface of the workpiece; 8), machining by bench workers; 9), surface treatment; 10), machining by the borers for graduating the workpiece in a comparison manner. The method has the advantages that the end sides of the uniformly distributed annular surfaces on the circumferential surface of the regulating ring part are partially lengthened to the certain quantities, so that phenomena of tool breakage and the like in an existing machining procedure are prevented, and the quality of the product is effectively guaranteed.

Description

A kind of adjustable ring machining parts

Technical field

The invention belongs to the machined field, be specifically related to a kind of scale adjustable ring machining parts.

Background technology

The part that often needs the processing different shape in actual production, the part that meets designing requirement that processes that how can craftsmenship has very important significance.For adjustable ring part as shown in Figure 1, it is the difficult point of processing that uniform ring surface is arranged on its periphery, if process with the boring machine boring cutter, because be semicircle orifice, second half part does not have entity, the bad processing of boring cutter does not guarantee desired precision thereby be prone to the such processing of phenomenon such as forge a knife.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, a kind of adjustable ring machining parts is provided.

For achieving the above object, the technical solution used in the present invention is: a kind of adjustable ring machining parts:

1) prepares material;

2) turner processing: rough turn profile, to the distolateral 15 ~ 20mm that high-volume lengthens of uniform ring surface on the excircle of workpiece face, remainder stays 2 ~ 3mm surplus;

3) heat treatment;

4) blast;

5) turner processing: according to profile in the drawing dimensional requirement finish turning workpiece, to distolateral 15 ~ 20mm surplus of still staying of uniform ring surface on the excircle of workpiece face; To being the profile car not of benchmark with uniform ring surface on the excircle of workpiece face distolateral, all the other profile finish turnings are to size;

6) borer processing: with the high-volume elongated portion clamping of the uniform ring surface end of workpiece, use the boring cutter of corresponding size then, the centering size bores a hole, then by 360 °/n of dividing head rotation, wherein n is the quantity in hole, the next hole of boring again, and the like to all boring until n hole, bore the hole of all the other positions at last behind the centering;

7) turner processing: remove redundance according to the ring surface degree of depth, the finish turning workpiece is the profile of benchmark with the distolateral of uniform ring surface on the periphery;

8) pincers worker processing: remove burr, profile end face sharp edge rounding;

9) surface treatment;

10) borer processing: with corresponding part contrast groove, finish the processing of adjustable ring.

Beneficial effect of the present invention: the present invention is by the distolateral part length high-volume that increased of ring surface uniform on the periphery of adjustable ring part, phenomenon such as avoided in process, occurring forging a knife, the Man Kongneng that processes guarantees needed dimensional accuracy, effectively guarantee the quality of product, improved the accepted product percentage of product.

The material of adjustable ring of the present invention is No. 45 carbon steel, this kind material easy deformation in process, consider the machining accuracy that this characteristic and part need, thereby increased the heat treatment method of modifier treatment, make intensity, plasticity and the toughness of steel all better by modifier treatment, have good comprehensive mechanical performance.

The specific embodiment

1 one kinds of adjustable ring machining parts of embodiment

The part of the adjustable ring shown in Fig. 1 ~ 3, as can be seen from the figure the difficult point of this part processing is that on the shaft shoulder periphery of left end head φ 64mmh8mm 30 radiuses to be arranged be the uniform ring surface of the dark 1.4mm of R2.6mm, this ring surface cooperates other part to use can regulate scale, if process with the boring machine boring cutter, because be semicircle orifice (about 1/3 circle), remaining part does not have entity, and the bad processing of boring cutter is prone to phenomenon such as forge a knife, and such processing does not guarantee required precision.

A kind of adjustable ring machining parts of the present invention is as follows:

1) prepare material: the forging blanking requires material intact, flawless, no sand holes;

2) turner processing: rough turn profile, workpiece left end (being the distolateral of uniform ring surface on the periphery) is high-volume lengthened 15 ~ 20mm, remainder stays 2 ~ 3mm surplus;

3) heat treatment: modifier treatment, No. 45 steel after quenching are carried out tempering between 500-650 ℃, tempering time had been not less than 1 hour, guaranteed back saturating.The modified performance that can make steel, material is adjusted significantly, and its intensity, plasticity and toughness are all better, have good comprehensive mechanical performance.

4) blast: carry out the blast operation after the heat treatment, its objective is the cleannes that improve piece surface, increase the residual compressive stress of piece surface;

5) turner processing: according to profile in the drawing dimensional requirement finish turning workpiece, the workpiece left end is still stayed 15 ~ 20mm surplus; Be the profile car not of benchmark to workpiece with uniform ring surface on the periphery distolateral, the cannelure of R2.5mm is not processed earlier in that this procedure is temporary transient in the present embodiment; All the other profile finish turnings are to size, and the annular tank car of R1.8mm is to size in the present embodiment;

6) borer processing: with workpiece left end elongated portion clamping, use the boring cutter of φ 5.2mm then, the centering size bores the hole of a φ 5.2mm, change 12 ° (angle of changeing is 360/30 degree) by dividing head then, the hole of the next φ 5.2mm of boring again, and the like to all boring until the hole of 30 φ 5.2mm, boring right-hand member φ 38mmH8mm hole behind the last centering;

7) turner processing: as shown in Figure 4, the left end of aa line is size high-volume, and the right-hand member of aa line is the entity size of processing, remove unnecessary high-volume size along the aa line, the control ring surface degree of depth is 1.4mm, the cannelure of chamfering finish turning profile R2.5mm, control 9.9mm size;

9) surface treatment: turn blue in the surface, forms the layer protecting film of part with chemical method;

10) borer processing: with corresponding part contrast groove, as the groove among Fig. 1, live width is 0.1mm, finishes groove as required, finally finishes the processing of adjustable ring.
