Fundamentally speaking, this technology is relatively simple: a rubber pad is embedded in the bearing cage. When proper pressure is applied to the piston, rubber will deform under pressure like liquid, and then the finished product can be obtained by some appropriate technical means.
Its advantages are as follows:
1, the processing cost is greatly reduced, generally by 90%;
2, the delivery cycle is greatly shortened;
3, the processing adjustment is simple and efficient;
There are almost no scratches during molding, and a piece of metal with a very smooth surface can be pressed into the required pattern.
Disadvantages are as follows:
1, the proportion of the feeding roller table must be accurate and cannot exceed the specified requirements;
2. The finished product rate of materials is low, so it is generally recommended to use a larger conveying space to prevent the materials from folding (due to the effect of the guard on the edges of materials).
3. It is necessary to provide a greater pressing force on the rubber pad than in conventional production, which often makes it impossible to process ultra-thin steel plates (usually the working pressure is about 500 tons).
4. The main reason for the limited production capacity is that the rubber pad itself will be deformed abnormally; On the one hand, in any case, the secret of rubber pressing is that the strip rubber near the inserted auxiliary chopping block or interface enters the appropriate position.
5. Generally, it can only be processed into a rough shape, and the final forming and taking-out operations still need to be completed manually. In addition, the elastic deformation of some high-strength materials is also a problem.
