Therefore, we can see that this processing method will have defects that are large at both ends and small in the middle, and if the depth of the hole is too deep, there is basically no way to process it. In fact, it is difficult to process if the depth of the hole exceeds 300mm. , so it also limits some of its applications. Even after the product is released from the mold as a whole, it is difficult to ensure that the concentricity of the product is within 0.05mm. In addition to the above-mentioned conicity problem, it is generally used for cutting correction on a grinding machine, but There is no seam problem with this method

Embodiment Construction
[0030] refer to figure 1 , Figure 4 and Figure 5 , the invention discloses a method for making a rubber roller, which is characterized in that it includes step 1, processing a mold and preparing materials,
[0031] The mold includes a patrix 1, a bottom mold 2 and an inner mold 3. The patrix 1 includes a rectangular patrix box 4. The patrix box 4 is provided with an upper module, and the upper module is provided with an upper semicircular groove: the bottom mold 2 includes Rectangular bottom mold box 5, the bottom mold box 5 is provided with a bottom module, the bottom module is provided with a bottom semicircular groove, and after the upper mold 1 and the bottom mold 2 are closed, the upper semicircular groove and the bottom semicircular groove form the first cylindrical cavity, The inner mold 3 is a circular tube, and is located in the first cylindrical cavity when the mold is closed, and can be straightened through the first cylindrical cavity. The upper module is oppo...

Abstract
The invention discloses a manufacturing method of a rubber roller. The rubber roller is manufactured by adopting a mode of combining an upper mold, a base mold and an inner mold, so that the processing difficulty is low, and a product is not required to be conveyed to a grinding machine for cutting, and the concentricity and the circular degree of the product can be ensured. According to the method, steps are simple, the cost is low, and the production efficiency is good, and also the method is suitable for processing super long products; moreover all physical sizes are very good; and the rubber roller product obtained through the method is extremely good in surface smoothness, and is good in circular degree and straightness, and the cost is greatly lowered.
Description
technical field [0001] The invention relates to a rubber roller, in particular to a manufacturing method of the rubber roller. Background technique [0002] At present, the manufacturing process of rubber rollers is generally divided into two types, one is the double-opening method, and the other is the overall mold-out method. [0003] The method of the two mold opening method is: the mold (such as image 3 (shown) is divided into two semicircular cavities, upper and lower. When working, put the shaft core first, then close the mold, inject glue, vulcanize, open the mold and take out the product. The advantage of this method is that the mold structure is simple, easy to process, and the concentricity between the shaft core and the rubber outer circle is relatively high. The disadvantage is that there are two seam lines caused by the mold, so the product must undergo secondary processing, such as grinding on a grinder. Cutting, etc., we know that the cutting of rubber is ve...
