Outer field material selection 45# steel; The material selection 40Cr of internal layer.
Compared with prior art, the present invention has following advantage:
1, the present invention adopts double-decker, makes layer structure to recycle like this, and endothecium structure is convenient for changing.
2, internal layer of the present invention adopts material 40Cr and handles through high-frequency quenching, and the outer steel ring that adopts is reinforced, the steel ring material adopts 45# steel Quenching Treatment, this structure not only satisfies the hard short fiber material needed hardness that is pressed, and also satisfies the wear-resisting requirement in the course of the work of ring mould.
3, ectonexine of the present invention adopts interference fit, and ring mould internal layer adopts embedded fixed structure with outer at ring mould edge, the relative slip between effectively anti-stop ring mould double-layer structure.
4, the annular distance on ring mould layer structure inwall is provided with chamfering, effectively solves the Concentricity tolerance of annular distance; The annular distance afterbody is provided with reaming, effectively discharges the pressure of the granulation generation of ring mould and material.
5, the prominent handle on the internal layer embeds in the groove that encircles on the mould skin in the structure, and the axial location by this device adjustment ectonexine structure reduces rigging error to greatest extent.
6, the layer structure inwall groove of beginning to speak can prevent effectively that endothecium structure is when changing, to the damage of layer structure.
7, through long-term pilot plant test, the ring die pelletizing ratio of briquetting of this structure reaches more than 95%, is higher than other like products 1.5-2 its service life doubly.When guaranteeing higher material ratio of briquetting, effectively reduced the manufacturing cost of ring mould, and can be pressed hard short fiber material.
