Abstract
An extruding screw body comprises a movable screw sleeve with flat hole made of hard alloy, which sleeves around the flat axle of extruding screw body made of ordinary steel, and a hole-forming tip made of ordinary steel and connected via pin to extruding screw body, both constituting a detachable whole. A bushing is inlaid on compression formed position of inner conic surface of forming sleeve barrel. They are important antiwear parts of extrusion forming apparatus, and feature long service life (more than thousand hr. or more than 12 months). They also are ideal energy-saving parts for making solid fuel with loose materials and materials.
Description
A kind of hard alloy extruded screw body, forming sleeve bushing and uses thereof belong to mechanical field, particularly are used to push loose living beings and mineral matter, make extruded screw body, sleeve bushing that solid-fuelled extrusion equipment is used.
Loose living beings and mineral matter are compressed into closely knit fuel rod or coal rod as the agricultural crop straw of sawdust, rice husk, pulverizing, coal dust etc. through single lead screw ex truding briquetting machine, become machine-made carbon through charing.In the compression forming process, its extruded screw body helical pitch conveyor screw foremost produces the pressure of tens Mpa to material, cause the front end wearing and tearing of extruded screw body very serious, the general common spiral of manufacturing with No. 45 steel of extruding, only can continuous operation tens hours, it is cisco unity malfunction, have to unload from extruder and carry out repair welding, reach original physical dimension through shaping, refill machine work, both made utilize that hard material sprays that (or surfacing) handle extrude spiral, stream time tens hours only.Extrude the heavy wear of spiral and frequent dismounting and repair again, cause and produce frequent interruption, efficient reduction, also waste energy and raw material simultaneously; The forming sleeve of single lead screw ex truding briquetting machine, though the rate of wear is slower than the rate of wear of extruding spiral, its working life also has only about one month, single wearing and tearing mainly occur on the band conical surface compression forming section, scrapping whole forming sleeve because of local damage also is that a machine is wasted greatly, and above technical problem has influenced applying of loose living beings and mineral matter technology for compressing and forming greatly.
The objective of the invention is to provide a kind of hard alloy extruded screw body, forming sleeve bushing in order to address the aforementioned drawbacks.
Technical scheme of the present invention is as follows: extruded screw body is movable spiral head of band and the top dismantled and assembled integral body of pore-forming that is built in sections with different materials, the movable screw rotation set is the sleeve shape body that flat hole is arranged with the carbide alloy manufacturing, be enclosed within on the flat axle of the extruded screw body made from common iron, pore-forming is top to be made by common iron, by pin it is linked to each other with extruded screw body, and make movable screw rotation set and extruded screw body axial restraint; The solid inner conical surface at forming sleeve of lining edge is compressed into screw-casing and extruded screw body axial restraint; The lining edge is solid at the inner conical surface compression forming position of forming sleeve, becomes the important wear resistant mechanical component of extrusion formation equipment.
Advantage of the present invention is to adopt reach respectively more than over thousands of hour and 12 months the service life of carbide alloy manufacturing activities screw-casing and lining, than the raising of making more than hundred times and ten times with common iron, the stream time of single lead screw ex truding briquetting machine is prolonged significantly, be loose living beings of extruding and mineral matter, make solid-fuelled desirable energy-saving equipment.

Fig. 3: forming sleeve structure cut-away view of the present invention
Be further described in conjunction with the accompanying drawings: make extruded screw body with carbide alloy, key is an extruded screw body 1, be the movable spiral head 2 of band that is built in sections with different materials and the dismantled and assembled integral body of pore-forming top 5, movable screw rotation set 2 is sleeve shape bodies that flat hole is arranged of making of the YG8 carbide alloy, be enclosed within on the flat axle 3 of the extruded screw body of doing with No. 45 steels 1 (as Fig. 2), pore-forming top 5 is done by No. 45 steels, by pin 4 it is linked to each other (as Fig. 1) with extruded screw body 1, and make movable screw rotation set 2 and extruded screw body 1 axial restraint; Be fixed on the inner conical surface compression forming position of forming sleeve 7 with the sleeve bushing 6 usefulness brazings of carbide alloy manufacturing, make it non-slip, do not scurry position (as Fig. 3); This extruded screw body and the sleeve bushing made from the YG8 carbide alloy, be to be used to push loose living beings and mineral matter to make important wear resistant mechanical component on the solid-fuelled extrusion equipment, reach respectively the service life of movable screw rotation set 2 and sleeve bushing 6 more than over thousands of hour and 12 months, than the raising of making more than hundred times and ten times with common iron.
Claims (3)
