Abstract
The invention discloses a kind of processing method of locking plate, comprise the following steps：Step 1: steel plate is processed into fan-shaped blank material；Step 2: the center section of fan-shaped blank material is suppressed into groove by size requirement；Step 3: compressing fan-shaped blank material redundance is carried out into laser ablation, inside and outside circular arc respectively stays certain surplus；Step 4: the workpiece after excision is heat-treated；Step 5: the reserved surplus of the Workpiece internal-external circle arc after heat treatment is cut off, the size of product requirement is reached；Step 6: short transverse is repaiied into file to the size of product requirement；Complete the processing of locking plate.The present invention can improve locking plate passing rate of processing and dimensional stability, there is larger improvement compared with traditional sheet metal component processing method, and processing method has in place of certain use for reference, and meets the processing demand of locking plate.
Description
Technical field
The present invention relates to mach technical field, and in particular to a kind of processing method of locking plate.
Background technology
Locking plate is the vital part of turbogenerator, and most of rotor is all to be connected to one by blade and center rotating part
Rise, its vital part connected is exactly locking plate, locking plate there are many kinds, such as Fig. 1 is exactly one of which locking efficiency very high locking plate,
N number of blade can be locked simultaneously, be the newest development trend for engine locking plate, but this locking plate requirement on machining accuracy is very
Height, difficulty of processing is big.
The locking plate uses Conventional processing methods institute produced problem：
1st, locking plate material selection high temperature alloy metal plate material, due to the performance of high-temperature alloy material in itself, shaping difficulty than larger,
Resilience is big after shaping, is difficult to ensure design requirement.
2nd, locking plate is cambered surface molding part, is difficult to ensure that height dimension is consistent in short transverse.
3rd, the required precision of locking plate appearance and size is high, is much skillful in conventional sheet metal component appearance and size precision, size is difficult to ensure that,
Conventional method passing rate of processing bottom.
The content of the invention
In view of this, the invention provides a kind of processing method of locking plate, it is possible to increase locking plate passing rate of processing and size
Stability, there is larger improvement compared with traditional sheet metal component processing method, and processing method has in place of certain use for reference, and meets locking plate
Processing demand.
Realize that technical scheme is as follows：
A kind of processing method of locking plate, comprises the following steps：
Step 1: steel plate is processed into fan-shaped blank material；
Step 2: the center section of fan-shaped blank material is suppressed into groove by size requirement；
Step 3: compressing fan-shaped blank material redundance is carried out into laser ablation, inside and outside circular arc respectively stays certain remaining
Amount；
Step 4: the workpiece after excision is heat-treated；
Step 5: the reserved surplus of the Workpiece internal-external circle arc after heat treatment is cut off, the size of product requirement is reached；
Step 6: short transverse is repaiied into file to the size of product requirement, the processing of locking plate is completed.
Beneficial effect：
Processing method of the present invention, reserves certain allowance so that can after heat treatment before heat treatment
Qualified locking plate is processed further out according to the size requirement of locking plate, the present invention improves locking plate passing rate of processing and dimensionally stable
Property, there is larger improvement compared with traditional sheet metal component processing method.

Embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
The invention provides a kind of processing method of locking plate, comprise the following steps：
Step 1: it is the fan-shaped blank material that δ central angles are 90 ° that steel plate, which is processed into thickness,；As shown in Figure 3.
Step 2: the center section of fan-shaped blank material is suppressed into groove by size requirement；As shown in Figure 1, Figure 2 and Figure 4,
When compacting tool set is designed, profile angle carries out the processing and fabricating of compacting tool set according to the upper limit of tolerance：This is in order to full
Sufficient workpiece has the surplus for repairing file in the later stage；
Step 3: compressing fan-shaped blank material redundance is carried out into laser ablation, inside and outside circular arc respectively stays certain remaining
Amount；As shown in figure 5, be the workpiece of first time laser ablation, H is the semidiameter of the inside and outside circular arc after first time laser ablation.Should
The excision of step is that it is for energy after being heat-treated to leave certain surplus in order that obtaining workpiece can be put into the frock of heat treatment
The radius of the inside and outside circular arc of workpiece is further finished, surplus is left for finishing, in heat treatment, frock energy used
Ensure that the thermal deformation of workpiece is as small as possible, but workpiece still can have trickle change in size in frock, so needing reserved
Allowance, it is ensured that after heat treatment, moreover it is possible to further finished to workpiece, reaches product size requirement；
Step 4: the workpiece after cutting is heat-treated；The purpose of heat treatment：Distortional stress is eliminated, product is improved
Energy；
Step 5: the reserved surplus of the Workpiece internal-external circle arc after heat treatment is carried out into laser ablation, product requirement is reached
Size；As shown in fig. 6, being the workpiece after second of laser ablation.G ± 0.05 is the chi of the semidiameter of final inside and outside circular arc
It is very little.
Step 6: short transverse is repaiied into file to the size of product requirement；As shown in fig. 7, to repair the workpiece after file.F±
0.05 and E ± 0.05 be the final short transverse of workpiece size.
Thus complete the processing of locking plate.
Then, the detection of workpiece is carried out：1st, whether the locking plate surface that fluoroscopic examination is processed has crackle；2nd, locking plate is detected
Whether appearance and size is qualified；
In summary, presently preferred embodiments of the present invention is these are only, is not intended to limit the scope of the present invention.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the present invention's
Within protection domain.
