Description
Technical field
The present invention relates to a kind of manufacturing methods of PDC drill bit, disclose a kind of manufacture PDC drill bit rubber pattern
The production method of tool.
Background technique
PDC drill bit is a kind of dedicated boring tool of indispensability of geological drilling industry, has production complexity, required precision
High, the high feature easy to damage of value, manufactures the production of PDC drill bit rubber mold, is one for manufacturing PDC drill bit
Important intermediate link.It is raw seriously to restrict PDC drill bit for production precision, the efficiency for manufacturing PDC drill bit rubber mold
Production process.Traditional manufacturing method speed is slow, low efficiency, low precision, lacks normalization.
Summary of the invention
In view of the above-mentioned problems, the purpose of the present invention, is to focus on solving restrict manufacture PDC drill bit rubber mold one
The dedicated production method of kind.
1, present invention is characterized in that a kind of production method for manufacturing PDC drill bit rubber mold, specifically includes that material
Material prepares, and makes casting moulds, prepares the key steps such as rubber slurry, casting, solidification demoulding.
2, implementation step is as follows:
1) material prepares
According to geology characteristic, the U-shaped master mold of PDC drill bit, the core model for meeting drilling requirements are designed and produced.Selection, which meets, to be set
Meter production require vacuum electric hot tank, electronic scale, burette, the rustless steel container of belt stirrer, plastics mark flower bag (funnel),
The tools such as spanner.
2) casting moulds are made
The U-shaped master mold of PDC drill bit for meeting drilling requirements is cleaned out, is put into drying box and dries 20min, drying
Temperature is set as 65-75 DEG C.
Core model is mounted on U-shaped die cap panel holder, with clean gauze dip in release grease be uniformly applied to U-shaped master mold inner wall and
Core model outer wall.
U-shaped master mold is placed on bracket, core model is fitted into master mold cavity, it is rotated both clockwise and counterclockwise respectively,
Suitable core model position location is selected, positioning is fixed using bolt of long stem, casting moulds cavity is made.
3) rubber slurry is prepared
Appropriate silicon rubber material, accelerator are weighed according to die size, and the ratio of silicon rubber and accelerator is preferably 65: 1.
By in the rustless steel container of silicon rubber material merging belt stirrer, accelerator is added, is stirred until homogeneous rapidly.
The silicon rubber slurry being stirred is put into vacuum machine to carry out vacuumizing degasification, is evacuated to vacuum degree 0.08MPa.
4) it is poured
Silicon rubber slurry after degasification is used into aperture funnel, U-shaped mould and core model shape are injected rapidly by U mould bottom injection hole
At casting rubber pattern cavity in, casting process should be designed strictly and is poured.It is required that disposal pouring is completed and in plug hole
There is a certain amount of spilling at place.Wooden mallet tap mold in marginal not side is wanted to be poured uniformly closely knit bubble-free in casting process.
5) solidification demoulding
After rubber slurry casting complete, solidified using spontaneous curing mode, curing time was with 12_24 hours or so
Preferably.
After the completion of rubber slurry solidification, the rubber mold after curing molding is modified first, is carried out after finishing molding
Demoulding.
Demoulding sequence are as follows: first remove U-shaped die cap plate, further take out core model, then by rubber pattern peripherally to center gently according to
Secondary pulling after waiting peripheries all to loosen, slowly takes out rubber pattern, and it is qualified to examine again by design requirement, can be transferred to other processes
It is fabricated.
Above-mentioned work is completed, that is, completes the production work of manufacture PDC drill bit rubber membrane tool.
Specific embodiment
