Abstract
The utility model relates to a cone crusher can satisfy the wear -resisting requirement of ratchel breakage to rolling the mortar wall at broken building stones in -process, can satisfy the breakage of rocklet piece again to the cone crusher who comprises potassium steel and high -carbon chromium steel rolls mortar wall of the wear -resisting requirement of rolling the mortar wall, roll mortar wall upper portion for potassium steel, roll mortar wall lower part for high -carbon chromium steel and roll mortar wall upper portion and roll mortar wall lower part and be unsmooth founding cooperation. The advantage: firstly, fundamentally has solved the homogenous material and has rolled the mortar wall at broken building stones in -process, because the building stones of different specifications are different to the wearing and tearing volume of rolling the mortar wall, the wearing and tearing of mortar wall upper portion are little, the lower part wearing and tearing are big and the broken chamber of building stones that lead to forms the recess and the critical defect of unable broken building stones for rolling of causing, secondly, the potassium steel that rolls mortar wall upper portion rolls mortar wall lower part at the produced wearing and tearing volume of broken building stones and high -carbon chromium steel, and to roll the wearing and tearing volume in broken building stones chamber unanimous relatively.
Description
Technical field
The utility model relates to a kind of gyratory crusher can meet the broken wear-resisting requirement to rolled mortar wall of ratchel in broken building stones process, the broken gyratory crusher rolled mortar wall be made up of potassium steel and high-carbon chromium steel to the wear-resisting requirement of rolled mortar wall of finger stone and preparation method can be met again, belong to gyratory crusher component assembly and manufacture field.
Background technology
CN101954456A, title " for casting the manufacture method of the metal mold of gyratory crusher manganese steel crushing wall or rolled mortar wall ", manufacture method comprises the steps: (1) according to breaking wall of spindle breaker or the different size specification model of rolled mortar wall, manufactures the natural pattern of crushing wall or rolled mortar wall; (2) metal mold and the outer metal mold of nearly shape in corresponding wall thickness, integrally-built nearly shape is manufactured and designed respectively according to the shape of natural pattern; (3) in closely, metal mold and nearly outer metal mold lay flaring steam vent; (4) nearly interior metal mold and nearly outer metal mold, natural pattern are assemblied on mold(ing) board, reserved die cavity.But, because the be crushed to fritter building stones fragmentation of gyratory crusher from oversize rock material in the process of broken building stones is two kinds of different duties, its rolled mortar wall top is used for broken oversize rock material, what oversize rock material was formed rolled mortar wall top is impact load, and that what building stones and rolled mortar wall and crushing wall were formed is is uncertain, be not that the impact extruded of whole contact coordinates, thus relative with the state of wear on crushing wall top little to rolled mortar wall; And to be rubble roll rolled mortar wall and crushing wall bottom manufactures chamber, broken little building stones and rolled mortar wall form the rubble of plyability, completely contact, its broken gravelstone between rolled mortar wall and crushing wall is little under the brute force extruding of rolled mortar wall and crushing wall, broken little building stones to roll mortar ward off and the wearing and tearing of crushing wall very serious.If adopt homogenous material to make rolled mortar wall and crushing wall, no matter be potassium steel, or rich chromium cast iron, because the building stones of different size are different to the wear extent of rolled mortar wall, result causes rolled mortar wall and crushing wall Upper wear is little, middle part wearing and tearing opposite upper parts is little and the situation of bottom wearing and tearing formation groove, causes rolled mortar wall and crushing wall wearing and tearing to scrap.
Utility model content
Purpose of design: avoid the weak point in background technology, design a kind of gyratory crusher and can meet the broken wear-resisting requirement to rolled mortar wall of ratchel in broken building stones process, the broken gyratory crusher rolled mortar wall be made up of potassium steel and high-carbon chromium steel to the wear-resisting requirement of rolled mortar wall of finger stone can be met again.
Design: in order to realize above-mentioned purpose of design.The utility model is in structural design: 1, rolled mortar wall top is potassium steel, rolled mortar wall bottom is the design of high-carbon chromium steel, is one of technical characteristic of the present utility model.The object of such design is: potassium steel is opposing thump, one of optimal selection in the high-abrasive materials such as large pressure material wearing and tearing, it not only has the incomparable Work Hardening Characteristic of other high-abrasive material, and in greater impact load or compared with under the effect of large contacting stress, the top layer of its potassium steel produces work hardening, case hardness rises to more than HRC45 rapidly by HRC17--21, and along with the wearing and tearing gradually of cementation zone, new work hardening layer can successively be formed, thus produce endlessly while high abrasion superficial layer, and potassium steel internal layer austenite still keeps good impact flexibility.The utility model utilizes this characteristic of potassium steel just, the top of rolled mortar wall (or middle part and top) is adopted potassium steel, because rolled mortar wall top is for broken building stones, what building stones were formed rolled mortar wall top is impact load just, thus rolled mortar wall case-hardening can be made, hardness promotes rapidly, meets rolled mortar wall top to the hardness requirement of rubble and wear-resisting requirement; And high-carbon chromium steel carbon containing Wc is about 1%, chrome content Wcr is about 1.5%, and the hypereutectoid steel containing a small amount of manganese, element silicon.Chromium can improve heat treatment performance, improve quenching degree, structural homogenity, temper resistance, can improve again rustless property and the grinding performance of steel, its hardness reaches HRC63 ± 3, has excellent wearability, meet the wear-resisting requirement rolling broken building stones, its wear extent is significantly less than potassium steel.2, rolled mortar wall top and rolled mortar wall bottom are that concavo-convex clamping engages is technical characteristic two of the present utility model.The object of such design is: the convex-concave on rolled mortar wall top be connected in the concaveconvex structure of rolled mortar wall bottom, rolled mortar wall bottom synchronous can be driven to rise when rising under the effect of rolled mortar wall top in external force, thus reach the size of Longkou (crusher chamber) between convenient adjustment rolled mortar wall and crushing wall.
Technical scheme: a kind of gyratory crusher rolled mortar wall be made up of potassium steel and high-carbon chromium steel, rolled mortar wall top is potassium steel, rolled mortar wall bottom is high-carbon chromium steel and rolled mortar wall top and rolled mortar wall bottom are concavo-convex founding coordinates.
The utility model is compared with background technology, one is fundamentally solve homogenous material rolled mortar wall in broken building stones process, because the building stones of different size are different to the wear extent of rolled mortar wall, the rolled mortar wall Upper wear caused is little, bottom wearing and tearing are large and the building stones crusher chamber that causes forms groove and cannot the critical defect of broken building stones; The wear extent that two is wear extenies of producing at broken building stones of the potassium steel on rolled mortar wall top rolls broken building stones chamber with high-carbon chromium steel rolled mortar wall bottom is relative consistent, thus broken building stones chamber is rolled in the broken building stones process of stone roller in the rolled mortar wall bottom fundamentally solving homogenous material, due to wear extent be greater than rolled mortar wall Upper wear amount cause the situation of groove, not only greatly extend the service life of rolled mortar wall, and while the manufacturing cost greatly reducing rolled mortar wall and use cost, reduce broken building stones cost.
