Description
Technical field
The present invention relates to hydraulic valve manufacture field more particularly to a kind of hydraulic valve deep hole processing technologies.
Background technique
When processing according to traditional deep hole processing technology to hydraulic valve, front and back is carried out in two steps, and its processing technology
It is as follows: roughing first being carried out using drill, the prebored hole of diameter of phi 50mm is drilled out in advance and then is finished, specifically pair
Prebored hole carries out the Finish Machining Bore that boring processing obtains machine-shaping.During actual processing, because roughing adds with what is finished
Work benchmark disunity, the centre of location disunity of above-mentioned roughing prebored hole and Finish Machining Bore, aperture surplus is uneven, thus only
Energy boring processing, i.e., processed on boring machine.It is practical to grasp due to feed narrow space but when being processed using boring machine
Make highly inconvenient, along with the depth of above-mentioned deep hole is very big, needs to correct preboring hole site by special elongated boring cutter bar
Deviation, bite is small, and consuming time is long, and processing efficiency is very low, seriously restrict the execution cycle of product, simultaneously because
The portion of hydraulic valve will appear internal stress in process, be easy to cause in hydraulic valve when processing to thin-walled hydraulic valve
Wall deforms, so as to cause scrapping for hydraulic valve；Simultaneously because hole is deeper, work in-process is easy to appear shake knife mark, shakes knife
So that circumferential size appearance significantly changes, defect rate is higher for the appearance of line.
Summary of the invention
It is an object of the invention to: for the inside meeting for solving existing deep hole processing technology hydraulic valve in process
Internal stress occur is easy to cause hydraulic valve to scrap while the higher problem of defect rate, provides a kind of hydraulic valve deep hole machining
Technique.
The technical solution adopted by the invention is as follows:
A kind of hydraulic valve deep hole processing technology, the technique the following steps are included:
S1. first time roughing, using deep hole drill to hydraulic valve carry out first time drilling roughing, formed depth with
Diameter is respectively less than the roughing hole of size needed for deep hole；
Hydraulic valve obtained in step S1 is put and carries out high-temperature process in an oven, answered in removal by S2. high-temperature process
Power；
S3. depth finishes, and depth finishing is carried out to hydraulic valve using drill gun, until depth needed for deep hole；
S4. reaming carries out reaming to the hole processed in step S3 using reaming bit, and the diameter needed for deep hole simultaneously stays
Have a margin 0.1mm；
S5. diameter finishes, and is finished using boring cutter to deep hole, until size needed for deep hole.
In above scheme, in the step S1, the drilling speed is 500rmin to 700r/min, the drilling into
It is not more than 0.2mm/min to speed.
In above scheme, in the step S2, high-temperature process is specifically, be placed on 100 DEG C~300 DEG C for hydraulic valve
6~12 hours in environment.
In above scheme, in the step S3, the feed technique of depth finishing is carried out to deep hole specifically: drill bit is forward
0.08mm is fed, then rewind 3mm, then F.F. 2.99mm, then feeds 0.08mm again, until depth needed for deep hole.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
The present invention eliminates the internal stress inside the hydraulic valve in deep hole machining, solves by increasing high temperature processing step
Having determined, the inside of hydraulic valve will appear internal stress and is easy to cause hydraulic valve existing deep hole processing technology in process
It scraps while the higher problem of defect rate, while passing through first time roughing, depth finishing, reaming, diameter four steps of finishing
Technique, solving existing deep hole processing technology, consuming time is long, and the low-down problem of processing efficiency greatly improved deep hole and add
The efficiency of work, while ensure that the quality of product.
