The invention belongs to flange part production technical field, be specifically related to a kind of in set the disc flange of interstitial hole and mounting hole Part processing method.
Background technology
Disc flange part as shown in Figure 1 is a kind of conventional flange part type.It can be seen that this disc flange Part include circle flange chassis, be located at the small end stretched out in the middle part of flange chassis and be located at the flange of periphery, flange chassis outside Circle, is provided with the interstitial hole penetrating small end in the middle part of flange chassis, flange chassis is evenly distributed with multiple kidney-shaped in the periphery of interstitial hole Hole.This flange part is connected with rotating shaft by interstitial hole, closely cooperates fixing by mounting hole and workpiece.Therefore, this flange part pair The profile tolerance of mounting hole, size tolerance requirements are relatively strict, and it only relies on Forging Technology to be difficult to make, and need to coordinate machine tooling Just can make.But how to design forging process and the specific implementation of machine tooling operation, make two parts can be more reasonable Be combined, become the insoluble technical problem of technical staff.
Summary of the invention
For above technical problem, the present invention provide a kind of in set the disc flange part processing side of interstitial hole and mounting hole Method, this processing method has carried out reasonable disposition to forging process and machine tooling operation, has had good processing effect.
The present invention is achieved by the following technical solutions:
Setting the disc flange part processing method of interstitial hole and mounting hole in a kind of, described disc flange part includes the method for circle Blue chassis, it is located at the small end stretched out in the middle part of flange chassis and is located at the flange excircle of periphery, flange chassis, in the middle part of flange chassis Being provided with the interstitial hole penetrating small end, flange chassis is evenly distributed with multiple mounting hole, described disc flange in the periphery of interstitial hole The processing method of part comprises the following steps:
(1) raw material is carried out saw material after heat, jumping-up, obtain blank;
(2) forging designed according to disc flange part shape is obtained after blank is carried out successively blocking and finish-forging process, This forging includes medial launder and is positioned at the kidney slot of medial launder periphery;
(3) it is punched out forging processing so that medial launder is penetratingly formed interstitial hole, and kidney slot is penetratingly formed mounting hole, Carry out the process of hot school;
(4) first carry out quenched, Shot Blasting, after visual examination, magnetic powder inspection, then carry out pressure-sizing, further after detection Carry out antirust treatment, obtain flange blank;
(5) inwall that rises by flange blank processes, and small end cylindrical, end face and interstitial hole are carried out turnery processing;
(6) small end is clamped, the surface of flange chassis and flange excircle is carried out rough turn process;
(7) mounting hole is carried out milling process, remove flash removed;
(8) surface of flange chassis and flange excircle is carried out finish turning process;
(9) carry out antirust treatment after checking, obtain disc flange part finished product.
As preferred embodiment, blocking and finish-forging process and use closed type forged or open type forging to carry out, and forging is punched out The monolateral surplus of mounting hole after process is 2mm, and the monolateral surplus of interstitial hole is 1.5mm, and the surplus at remaining position of forging is 1mm.
As preferred embodiment, step (2) and step (3) use 630T electric screw unit or 1000T hot forging Make unit to carry out.
As preferred embodiment, described forging is formed with the remaining block for rushing mounting hole location on flange excircle.
The invention has the beneficial effects as follows: the present invention forms mounting hole at forging process, effectively reduce the turning of machine tooling Time, made forge weight alleviates, and following process is convenient;Allowance is uniform, effectively saves raw material.
Accompanying drawing explanation
Fig. 1 is the structural representation of disc flange part;
Fig. 2 is the process chart of the present invention.
Label declaration: 1-flange chassis, 2-small end, 3-flange excircle, 4-interstitial hole, 5-mounting hole.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments.
With reference to Fig. 1, present invention disc flange part to be processed includes the flange chassis 1 of circle, is located in flange chassis 1 Small end 2 that portion stretches out and be located at the flange excircle 3 of periphery, flange chassis 1, is provided with in the middle part of flange chassis 1 and penetrates in small end 2 Between hole 4, flange chassis 1 is evenly distributed with multiple mounting hole 5 in the periphery of interstitial hole 4.
With reference to Fig. 2, the concrete technology step of the present invention is as follows.
Step (1), raw material is carried out saw material after heat, jumping-up, obtain blank.
Step (2), carries out blank obtaining after blocking and finish-forging process designing according to disc flange part shape successively Forging, this forging includes medial launder and is positioned at the kidney slot of medial launder periphery.This step can be forged with closed type forged or open type and be carried out. Location when kidney slot is punched out in subsequent step for convenience, forging is formed with remaining block on flange excircle, utilizes block more than this Location confirmation can be carried out, facilitate the work of punching location.
Step (3), is punched out forging processing so that medial launder is penetratingly formed interstitial hole, and kidney slot is penetratingly formed waist Shape hole, then carries out the process of hot school.It is 2mm that forging is punched out the monolateral surplus of mounting hole after processing, the monolateral surplus of interstitial hole For 1.5mm, the surplus at remaining position of forging is 1mm.
This step (3) and above step (2) use 630T electric screw unit or 1000T hot die forming unit to enter OK.
Step (4), first carries out quenched, Shot Blasting, then carries out pressure-sizing after visual examination, magnetic powder inspection, further Carry out antirust treatment after detection, obtain flange blank.
Above-mentioned steps (1) to (4) is Forging Technology implementation section.
Step (5), the inwall that rises by flange blank processes, and small end cylindrical, end face and interstitial hole are carried out turning adds Work.
Step (6), clamps small end, and the surface of flange chassis and flange excircle is carried out rough turn process.
