Processing technology of ring die hole
(1) Detection of hair embryo quality
(2) Calculate the opening rate
(3) Compile the hole program card of ring jig
(4) Input program to process die hole
(5) Die hole counterbore
The ring die chamfering machine is used to chamfer the hole of the ring die, and the deburring treatment is carried out after chamfering.
(6) Countersunk angle of die hole
The counterbore designed for granulation characteristics is called process counterbore: the counterbore designed for material characteristics is called working counterbore.
(7) Inspect whether the hardness of heat treatment is qualified
(8) Clean the die, apply anti-rust oil, pack and deliver
The production process of the pellet mill ring die and roller is very complex, which is mainly divided into five parts.
The first step is that the ring die pressing roller needs to undergo delicate finishing, and the size, shape, surface, etc. of the material should be precisely processed, and the material should be processed into exquisite ring die pressing roller.
The second step is to polish the surface with a grinder to completely remove the surface burr to achieve the effect of smooth surface.
The third step is to finish machining with diamond tools to make the roller surface perfectly smooth and completely remove the burrs on the surface.
The fourth step is to form a film on the surface of the roll surface after precise mechanical polishing to improve the wear resistance and corrosion resistance of the roll surface.
The fifth step is to complete the overall assembly of the roll surface and install the wear-resistant protection of the roll surface through warm rolling assembly, so as to make the roll surface more durable and prolong the service life of the product.
The above is the production process of the ring die and roller of the granulator, which can ensure the high quality of the ring die roller and provide better feed machinery and equipment for enterprises.
