Abstract
The invention relates to a circular cone type crusher composite dental lamella and composite forming method, and relates to a structure constitution and a material constitution for rolled mortar wall or broken wall of a cone type crusher. A composite toothed plate is made by finish machining surface of a high manganese steel tooth lining board and a back face of a high chromium cast iron toothed panel, forming the surface and the back face into interference surface contact or interference spaced surface contact, heating the high chromium cast iron toothed panel, and fitting over the surface of the high manganese steel tooth lining board to form interference matched with the surface of the high manganese steel tooth lining board, and cooling.
Description
Technical field
The present invention relates to a kind of formation of the structure for cone crusher rolled mortar wall or crushing wall and material and form, belong to cone crusher tooth plate and manufacture field.
Background technology
1, publication number CN1036149A, title " Boronized toothed plate group ", Boronized toothed plate group is a kind of by the pure iron tooth plate group product of boronising after processing in addition.
2, no matter the rolled mortar wall of existing cone crusher, crushing wall are in structural design, or in the selection of material, its rolled mortar wall and crushing wall all adopt potassium steel to make, but owing to being subject to the restriction of the material of potassium steel own, its hardness and wearability cannot meet hardness and the wear-resisting requirement of rolled mortar wall, crushing wall.Therefore, in the process of using, in the process that building stones are broken between rolled mortar wall, crushing wall, what between rolled mortar wall, crushing wall, form due to building stones is mandatory fragmentation, therefore, for the potassium steel rolled mortar wall little for hardness, anti-wear performance is poor, crushing wall, not only wear extent is large, and service life is short.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design a kind of circular cone type crusher composite dental lamella and composite forming method that can fundamentally improve rolled mortar wall, crushing wall hardness and scuff resistance.
Design: in order to realize above-mentioned purpose of design.1, composite dental lamella is designed to the composite dental lamella consisting of rich chromium cast iron flank of tooth plate and potassium steel tooth liner plate, is one of feature of the present invention.The object of doing is like this: the one, because flank of tooth plate directly contacts with wanted broken building stones, in the selection of material, not only require hardness large, and require anti-wear performance to get well, and the hardness of rich chromium cast iron material itself is far longer than potassium steel, anti-wear performance is the more than 3 times of potassium steel, therefore adopt rich chromium cast iron as the flank of tooth plate of composite dental lamella, not only can meet hardness requirement of the present invention, and can improve significantly the wearability of flank of tooth plate, the 2nd, because tooth liner plate does not directly contact with wanted broken building stones, therefore choosing of material, select, potassium steel tooth liner plate not only can meet hardness and the rigidity requirement of tooth liner plate, and because the hardness of potassium steel tooth liner plate is less than the hardness of rich chromium cast iron, when rich chromium cast iron flank of tooth sleeve-board is on potassium steel tooth liner plate, one is hard, between one soft two kinds of materials, can form stickiness coordinates, its coefficient of friction is very large, can guarantee the reliable connection between flank of tooth plate and tooth liner plate, and improving significantly rolled mortar wall, under the prerequisite of crushing wall hardness and wearability, reduced to greatest extent rolled mortar wall, the manufacturing cost of crushing wall.2, by the contact of interference face or the contact of interference septal surface that form after the back side fine finishining of the face of potassium steel tooth liner plate and rich chromium cast iron flank of tooth plate and between the two after expanding with heat and contract with cold, be two of feature of the present invention.The object of doing is like this: the one, because the hardness of potassium steel tooth liner plate is less than the hardness of rich chromium cast iron, after the heating of rich chromium cast iron flank of tooth plate, force to be enclosed within on potassium steel tooth liner plate, after the polished surface of rich chromium cast iron tooth back side of panel and fine finishining, potassium steel tooth liner plate face forms interference sealing combination, its stickiness is very large, thereby has realized purpose of design of the present invention.
Technical scheme 1: circular cone type crusher composite dental lamella, it comprises tooth plate, composite dental lamella is by flank of tooth plate (1) and tooth liner plate (2) composite molding.
Technical scheme 2: the composite forming method of circular cone type crusher composite dental lamella, the back side fine finishining of the face of potassium steel tooth liner plate and rich chromium cast iron flank of tooth plate and the face of the potassium steel tooth liner plate after fine finishining and the back side of rich chromium cast iron flank of tooth plate are formed to interference face contact or interference septal surface contacts, then heat rich chromium cast iron flank of tooth plate, rich chromium cast iron flank of tooth plate interference after heating is enclosed within on the face of potassium steel tooth liner plate and with the face of potassium steel tooth liner plate and forms interference fit, form composite dental lamella after cooling.
The present invention compares with background technology, the one, fundamentally solved the weak point that background technology exists, rolled mortar wall, the hardness of crushing wall, anti-wear performance have been improved, extended significantly its service life, and improving significantly under the prerequisite of rolled mortar wall, crushing wall hardness and wearability, reducing to greatest extent the manufacturing cost of rolled mortar wall, crushing wall; The 2nd, realized between rich chromium cast iron flank of tooth plate and potassium steel tooth liner plate reliably compound.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of circular cone type crusher composite dental lamella.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.Circular cone type crusher composite dental lamella, it comprises tooth plate, tooth plate refers to rolled mortar wall or crushing wall or rolled mortar wall and crushing wall.Composite dental lamella is by flank of tooth plate 1 and 2 composite moldings of tooth liner plate, and flank of tooth plate 1 adopts rich chromium cast iron, and tooth liner plate 2 adopts potassium steel.The making of rich chromium cast iron and potassium steel is prior art, at this, is not described herein.
Embodiment 2: on the basis of embodiment 1, the composite forming method of circular cone type crusher composite dental lamella, the back side of the face of potassium steel tooth liner plate and rich chromium cast iron flank of tooth plate is adopted to existing process equipment fine finishining moulding, and the face of the potassium steel tooth liner plate after fine finishining moulding and the back side of rich chromium cast iron flank of tooth plate guarantee to form interference face contacts or the contact of interference septal surface (septal surface contact refers to: between face (ring surface) and face (ring surface), be groove, the object of groove is: reduce weight and cost), then heat rich chromium cast iron flank of tooth plate, rich chromium cast iron flank of tooth plate interference after heating is enclosed within on the face of potassium steel tooth liner plate and with the face of potassium steel tooth liner plate and forms interference fit, after cooling, form composite dental lamella.The heating-up temperature of the heating-up temperature of rich chromium cast iron flank of tooth plate, potassium steel tooth liner plate is prior art, at this, is not described herein.
Embodiment 3: on the basis of embodiment 2, and heating potassium steel tooth liner plate, the face formation interference fit by the potassium steel tooth liner plate after heating with rich chromium cast iron tooth liner plate, forms composite dental lamella after cooling.
