Roll Plastic Process
This is roll plastic process machinery which is made to rotate a work and performs plastic-deformation processing.
As the greatest feature compared with cutting lathe, it can process a work without taking out chip.

And followings are features of the roll plastic process machinery :-
- Since giving the rolling plasticity by the roller press, the surface of processed work excels in the roughness.
- Comparing with other press processing, since the work is rotated, it excels in the roundness.

Processed Sample Work
Since this machinery processes a work by plastic deformation without taking out chip like cutting, what is a solid of revolution is basically processible.
Following photo is the processing example of alternator pulley.
Bar was put into the main hole and the five-step pulley slot was processed on the work's outer diameter.

Following photo is the processing example of alternator one-way clutch.
Deep groove for pulley belt was given to the outer diameter, and helical spline processing was give to the bore part at the same time.
In case of φ47mm, the cycle time is 10 sec.

How to operate
This roll plastic process machinery terminates the process only by one chucking rather than multi-processing the complicated work.

As a processing order :-
1. Chucking the work by autoloader
2. Pressurize and insert the chucked work in tail stock.
3. Pushing the work at both center, and plastic processing it by roller press.
4. After the processing, discharge the work with pusher, and collecting it by unloader.

The cycle time depends on the plastic processing time mostly.
It takes time for about 2 seconds to autoload and unload. (Loading time shall be changed depending on the shape of work.)

Following photo is enlargement of the chucking part.
Only the male mold roller is usually used in plastic processing.
In the machinery of the photo, the male mold roller is set for plastic processing one-step pulley.
And another male mold roller which make helical spline processing in the bore is used as bar for work chucking.
Such a processing which applies plastic deformation to both inside and outside diameter at the same time is materialized with the reliability to high rigidity or long-time automatic operation.

In order to enable full automatic operation for long time, the various autoloader and unloader with which the old track record guarantee the reliability are installed in this machinery.
The work which performs plastic processing has become complicated plentifully, considering the blank form.
According to user's request, we can manufacture and provide various autoloader, unloader and various conveyance support equipments suitable for each product shape.
