Abstract
The invention discloses a kind of processing method of the open vallecular cavity of web part, steps are as follows: thick the first face of precision-machined parts structure is in place；The second face of roughing structure；The second face of precision-machined parts end, top rib；Shape in the second face of precision-machined parts；The second face of precision-machined parts web；When the structure of the second face of roughing, the web surplus of open vallecular cavity is two times for closing vallecular cavity.When finishing the second face opening vallecular cavity web, cutting width is the half for closing vallecular cavity, and from open end feed, reciprocal feed later in place along web periphery machining profile finally completes web finishing.Processing method of the invention, it is possible to prevente effectively from bullet knife problem of the open vallecular cavity web in finishing, and the quantity that compression boss are around set is reduced, promote the processing efficiency and surface quality with open vallecular cavity part.
Description
Technical field
The present invention relates to metal cutting process fields, in particular to aerospace component numerical control processing field.
Background technique
Aerospace component is because assembly demand usually has open vallecular cavity, i.e., rib is endless totally-enclosed around vallecular cavity.It is such
For structure because open end lacks support, web rigidity is poor, in web finishing, easily causes and plays knife broaching tool, cause part
Quality problems.
This class formation traditional numeric-control method is as shown in Fig. 1, connects web using sheet connection boss, will be convex in processing
Platform compresses, and to guarantee rigidity of the part web in processing, is later removed boss by pincers worker, and in place by end polishing.
But drawback in this way of both processing presence: first, removal boss can generate more bench work amount, influence the processing of part
Efficiency；Second, even now ensure that the rigidity of part in numeric control, but difficulty has been transmitted to pincers worker, beat in pincers worker
Web rigidity is still poor when mill, and when polishing easily plays knife, very high to pincers worker level requirement.In actual production, due to pincers worker
The case for making mistakes when opening vallecular cavity web and causing part overproof or even scrapping of polishing happens occasionally.
Summary of the invention
The purpose of the present invention aims to solve the problem that the problem of conventional open vallecular cavity processing method, and providing one kind can be in numerical control
Open vallecular cavity complete stability is processed in place in process, is neither generated in process and is played knife broaching tool, do not need to clamp again
The processing method of work polishing.
The present invention is realized by following scheme:
A kind of processing method of the open vallecular cavity of web part, step are as follows:
Step 1, thick the first face of precision-machined parts structure is in place；
Step 2, the second face of roughing structure, for open vallecular cavity, web surplus is two times for closing vallecular cavity；
Step 3, the second face of precision-machined parts end, top rib；
Step 4, shape in the second face of precision-machined parts；
Step 5, the second face of precision-machined parts web, cutting width is the half for closing vallecular cavity.
In the step 5, when finishing open vallecular cavity web, from open end feed, reciprocal feed later, finally along abdomen
Plate periphery machining profile in place, completes web finishing.
The beneficial effects of the present invention are:
1, the processing stability of open vallecular cavity is improved, the bullet knife broaching tool being also easy to produce when the finishing of open vallecular cavity web is eliminated.
2, it can be not provided with false boss, reduce workload and quality risk when pincers worker polishing.
Detailed description of the invention
Fig. 1 conventional open vallecular cavity boss connection type.
Fig. 2 opens vallecular cavity web and finishes knife rail.
Specific embodiment
Embodiment 1
A kind of processing method of the open vallecular cavity of web part of the present invention, step are as follows:
Step 1, thick the first face of precision-machined parts structure is in place；
Step 2, the second face of roughing structure, for open vallecular cavity, web surplus is two times for closing vallecular cavity；
Step 3, the second face of precision-machined parts end, top rib；
Step 4, shape in the second face of precision-machined parts；
Step 5, the second face of precision-machined parts web, cutting width is the half for closing vallecular cavity.
In the step 5, when finishing open vallecular cavity web, from open end feed, reciprocal feed later, finally along abdomen
Plate periphery machining profile in place, completes web finishing.
Embodiment 2
By taking one of certain 7050-T7451 aluminum alloy part as shown in Figure 2 open vallecular cavity as an example:
The closing vallecular cavity roughing surplus of the part is web 3mm, rib 3mm.
Finishing uses diameter 12mm, and the solid carbide of bottom tooth radius 3mm is processed.
When closing the finishing of vallecular cavity web, cutting width is 6mm.
Then for open vallecular cavity, in roughing, the surplus of web is 6mm.When finishing web, cutting width is 3mm, tool
Body cutting line as shown in Fig. 2, from open end feed, in place along web periphery machining profile finally complete by reciprocal feed later
Web finishing.
Claims (2)
