Flat-die type powdered make-up machine mainly partly is made up of main shaft, mould, pressure roller, cutter, discharging disk and transmission mechanism etc.Flat mould (abbreviation flat-die) is the critical component of make-up machine, is the disk of processing many nibs according to certain rules.As required, can process the flat-die of different-diameter and the flat-die of different die throat diameters.Because of how biomass forming machine on the domestic market improves on the basis of feed granulator formed, the flat-die manufactured materials is generally selected common straightcarbon steel for use, and tensile strength and hardness are low, distortion easy to wear.Biomass moulding is different with feed, needs stronger pressure, and therefore, frictional force is big, and operating temperature is higher, if adopt the carbon steel material manufacturing, meeting is quick-wearing very.In order to solve flat-die rapid wear problem, flat-die also part adopts structural alloy steel, but the cost height, about 150,000 yuan of the mould of a production capacity 1t/h in about 500 hours of service life, causes the high enterprise of biomass fuel production cost.
Present widely used flat-die all adopts conical material guide hole.Material guide hole not only plays the guide effect, or the direct force part of material forming, existing circular material guide hole structure causes the different directions pitch of holes unbalanced, thereby unbalance stress, cause the distortion of the unbalanced and easy generation of charging nib to penetrate, thereby influencing the molding effect of biomass fuel, shaping efficiency is low, and has reduced to a great extent the service life of mould.
Flat-die machining also is one of key factor of its quality quality, but is not subjected to enough concerns, cause material to skid on the flat-die surface and can't compress into nib, or material compresses into nib but demoulding difficulty, thereby production efficiency is low, can't produce continuously.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and the biomass fuel forming die of a kind of production efficiency height, long service life is provided.
The technical solution adopted in the present invention is: the present invention includes die ontology, the center of described die ontology is provided with the mold center hole, also be provided with some nibs on the described die ontology, described nib comprises material guide hole I and moulding hole, described material guide hole I is polygon and is arranged on described die ontology upper surface, the aperture of described material guide hole I is greater than the aperture in described moulding hole, and described moulding hole links to each other with the bottom of described material guide hole I and runs through described die ontology.
Optimally, described nib also comprises material guide hole II, and described material guide hole II is polygon and is arranged on described die ontology lower surface, and the aperture of described material guide hole II is greater than the aperture in described moulding hole, and described material guide hole II links to each other with described moulding hole.
Described material guide hole I and described material guide hole II are hexagon.
The distribution that on described die ontology, assumes diamond in shape of described some nibs.
The height of described material guide hole I and described material guide hole II is 6～9mm, and the height in described moulding hole is 23～25mm.
The roughness of described die ontology upper and lower surface is Ra 3.2～6.3 μ m.
The roughness of the inner surface of described nib is Ra 0.4～0.8 μ m.
Described die ontology adopts the 40# carbon constructional quality steel.
The invention has the beneficial effects as follows: among the present invention, described die ontology is provided with some nibs, described nib comprises material guide hole I and moulding hole, described material guide hole I is polygon and is arranged on described die ontology upper surface, the aperture of described material guide hole I is greater than the aperture in described moulding hole, and described moulding hole links to each other with the bottom of described material guide hole I and runs through described die ontology; Under the prerequisite that the die ontology of same diameter and nib center distance equate, but the quantity of the polygon material guide hole structure arranged distribution nib that adopts among the present invention is equal to or greater than the number of orifices of existing circular material guide hole structure; And polygonized structure can guarantee the bridge width equalization, helps the stressed equiblibrium mass distribution of mould, avoids the too early mould of part nib to wear, and influences production capacity; Moreover, to compare with existing inscribed circle material guide hole structure, the polygon stress surface is bigger, is easy to the compacting material; Also the inner surface area that forms owing to the polygon material guide hole is bigger, thereby the increase of guide amount, can effectively reach the purpose that improves production capacity.
Among the present invention, described nib also comprises material guide hole II, and described material guide hole II is polygon and is arranged on described die ontology lower surface, and the aperture of described material guide hole II is greater than the aperture in described moulding hole, and described material guide hole II links to each other with described moulding hole; Be about to mould and make double-sided die, the double-sided die thickness of structure is than the thick approximately 8mm of one-side mould.When the worn out obstruction of the material guide hole I of die ontology upper surface is produced, turning die ontology uses the another side of mould, so promptly realize doubling the service life of mould, its cost only increases by 1/4, can further reach the effect that reduces production costs and improve service life.
