The Production Points of NCC Roll
NCC roll is an important forming tool in sheet metal processing areas, it is very important to ensure the quality and service life of NCC roll products. In order to properly understand the production points of NCC roll, the following important points should be considered:
1. Processing requirements: in the design of die size, it should meet the corresponding technical requirements or according to the product shape, size and other requirements. Selection of the rolling material should be adapted to the drawing requirements, and its surface hardness, tensile strength and yield strength should reach the corresponding requirements for rolling use.
2. The hardness of the rolling material: For the rolling material selected in accordance with the die size and shape requirements, the hardness should be greater than the hardness of the occurrence.
3. Grinding of the roller core: the grinding accuracy of the roller core should meet the requirements to ensure the roll surface qualification rate.
4. Control of the roller neck size: the roller neck size of the complete roller should meet the requirements, and the roll neck size can also be increased according to the size of the roll neck in forming process.
5. Assembly of roll body: when assembling the roll body, it is necessary to check whether the roll body, roller core and guide plate are installed in accordance with the size requirements, and whether the assembly screws are firmly fixed.
6. Heat treatment and stress relief: in order to ensure the accuracy of the roll dimension and avoid cracks, it is necessary to temper or temper the roll body before working.
7. Shape test: after machining and heat treatment of the roller body, it is necessary to check whether the roller body can meet the manufacture and assembly requirements, whether there are any defects and whether the model is up to standard.
8. QC inspection: during the production process, it is necessary to check the hardness of the roll surface, the roundness and the surface effect, and ensure the roll surface reaches the company standard.
To sum up, the above are the most important points that should be strictly enforced in the production of NCC roll. By following the points above, producers can rest assured that their rolls will meet the expected quality and performance standards.
