Background technology
At present, the manufacture craft of rubber rollers generally is divided into two kinds, and a kind of is two die sinking methods, and another kind is that integral body goes out modulus method.
The method of two die sinking methods is: mould (as shown in Figure 2) is divided into two semicircular die cavities up and down, puts into a core during work earlier, and product is taken out in matched moulds, injecting glue, sulfuration, die sinking again.The advantage of this method is simple, the easily processing of mould structure, the concentricity of axle core and rubber cylindrical is higher, shortcoming is because the bad mold joint that has two moulds to cause, therefore product must carry out secondary operations, for example go up grinding machine etc., we know that the cutting of rubber is very unmanageable, therefore cost is very high, and cutting rear surface roughness also difficulty lower, even if cutting is also had any different with other position in physical property and other aspect of performance later in the bad mold joint position simultaneously, thereby influences performance.
The method that integral body goes out modulus method is very high to mould (as shown in Figure 3) requirement, generally only is used for the rubber product of liquid perfusion type, at first will process a columniform die cavity, in two assembly heads are packed die cavity in addition, is used for fixing the metal shaft core that passes die cavity.A core pack during work earlier in die cavity, and two ends fix a core with assembly head, and product is taken out in injecting glue, sulfuration more then.Our columniform as can be seen die cavity has born main power thus, so the wall thickness of die cavity is generally very thick, and more than 5mm, material is generally selected the better rigidity steel for use, and the moulding of die cavity generally adopts methods such as grinding machine mill and Wire EDM to make.So we as can be seen, this processing mode all can have big, the middle little defective in two ends, if the degree of depth in hole is too dark, substantially just have no idea to reprocess, if in fact the degree of depth in hole just is difficult to process above 300mm is long, therefore also limit its some application, even after the whole depanning of product, because the concentricity of product is difficult to guarantee in 0.05mm, add foregoing conicity problem, generally can go up grinding machine yet and cut correction, but this method does not have the problem of bad mold joint.
