Description
Technical field
The present invention relates to oil sealing fields, and in particular to the production technology of oil sealing.
Background technique
The oil sealing of crane is generally made of skeleton, spring and rubber ring, and the effect of rubber ring is will to need in transmission parts
The component to be lubricated is isolated with external environment, is unlikely to allow oil seepage.In the manufacturing process of rubber ring, in order to guarantee original
Slurry amount is enough, needs that excessive slurry is added in a mold, and after slurry is full of mold, excessive slurry can be from the fastening of mold
Place is overflowed, and the slurry after spilling will form burr.It after rubber ring molding, needs to polish to burr, improves rubber ring and bone
The compactness of frame, it is ensured that will not allow oil seepage in use process.
Traditional rubber ring polishing is usually to have been manually done, i.e., operator holds cutter, along the inner wall of rubber ring and outer
Wall gradually grinds off burr, but such polishing mode efficiency is too low, and the labor intensity of operator is too big.Machine is mostly used now
Rubber ring, i.e., be placed in groove by tool polishing, pushes against the outer wall of rubber ring and groove walls, is then driven by servo motor
Polishing bar polishes to rubber ring inner wall.But this polishing mode can only polish to inner wall, and for hardness compared with
Low rubber ring, if polishing bar is just contacted with inner wall, rubber ring is likely to occur deformation, cannot achieve polishing；If beaten
Mill bar push against rubber ring inner wall, it is possible to cause rubber ring and polishing bar rotate synchronously, polishing bar always with rubber ring inner wall
One point contact, equally cannot achieve polishing；In addition, being needed after the completion of polishing to improve the effect that is adjacent to of rubber ring and skeleton
To be made a hole in rubber ring inner wall, install rubber ring when with skeleton on male cooperation, improve its stability, this undoubtedly increases
Process, reduces the processing efficiency of rubber ring.
Summary of the invention
Polishing is carried out the purpose of the present invention is to provide the inside and outside wall of a kind of pair of rubber ring and simultaneously to the inner wall of rubber ring
The technique punched.
In order to achieve the above objectives, the technical solution of the present invention is to provide the production technology of oil sealing, include the following steps:
Step 1: it is spare to prepare a kind of polishing agent, which includes 1-3 parts of polymerization inhibitor, and 4-8 parts of dispersing agent, abrasive material 15-
20 parts, 3~6 parts of powder lubricant, surplus is deionized water；
Step 2: preparing the first swelling body that rubber ring is fixed and the second swelling body, polish rubber ring
Sanding body and mill, the support rod for supporting sanding body and the perforating mechanism that rubber ring is punched；
Step 3: rubber ring sleeve being located at first after polishing agent described in step 1 is coated on the inside and outside wall of rubber ring
On swelling body and the second swelling body；
Step 4: the first swelling body and the second swelling body described in rotation step 2 pass through sanding body described in step 2 and mill
Disk polishes to the inside and outside wall of rubber ring；
Step 5: in step 4 in first swelling body and the second swelling body rotation process, perforating mechanism and support rod cooperation pair
The inner wall of rubber ring is punched.
This programme has the technical effect that the first swelling body and the second swelling body realize the fixation of rubber ring, it is ensured that rubber ring
Keep opposing stationary with the first swelling body, the second swelling body during the grinding process, no longer deformation occurs, in mill and sanding body
It is polished completely under effect the inside and outside wall of rubber ring；The agent that will polish before polishing simultaneously is coated in the inside and outside of rubber ring
Wall, abrasive material enclose increase rubbing action to rubber, improve grinding effect, and lubricant plays lubrication buffer function, reduce abrasive material to rubber
The scuffing of cushion rubber improves leakproofness when rubber ring uses；Cooperated again by perforating mechanism and support rod, is realized to rubber ring
Punch operation.
Further, polymerization inhibitor is 2 parts in polishing agent described in step 1, and dispersing agent is 6 parts, and abrasive material is 16 parts, powder profit
Lubrication prescription is 5 parts.This programme has the technical effect that it is demonstrated experimentally that improving the same of grinding effect with the polishing agent of ratio preparation
When utmostly guarantee that the inside and outside wall of rubber ring is not damaged, extend the service life of rubber ring.
Further, powder lubricant described in step 1 is hexagonal boron nitride.This programme has the technical effect that six side's nitrogen
Change boron also has certain corrosion resistance while with preferable lubricity, is coated to can on the inside and outside wall of rubber ring
To enhance the corrosion resistance of rubber ring.
Further, the partial size of the hexagonal boron nitride is 3~5 μm.Six sides for having the technical effect that the granularity of this programme
Boron nitride makes it will not influence rubber full leakproofness while being evenly distributed on the inside and outside wall of rubber ring.
Further, abrasive material described in step 1 is boron carbide and silicon carbide.This programme has the technical effect that boron carbide is hard
Degree is very big, reduces the abrasion of rubber ring, while silicon carbide reduces the heat that rubber ring friction generates, it is ensured that rubber ring after polishing
Quality is more excellent.
