Abstract
The utility model relates to a combined diamond grinding wheel, provided with a rigid circular disc basal body whose center is provided with an axle hole and periphery is provided with a rectangular section ring groove. The periphery of the basal body is embedded with diamond grinding blocks forming a grinding function layer through the rectangular section groove; solid lubricant is filled between every two grinding blocks; the embedded position of the basal body and the grinding blocks is provided with an axial fixed pin. As the utility model adopts a combined grinding wheel structure, the integral hot pressing sintering is changed into the separating unit hot pressing sintering, and that the diamond grinding wheel having a super-great diameter adopts the hot pressing technology for production is realized; the performance and the quality of products are improved; graphite jigs can be easily designed and combined, the group technology can be easily used in production, and the product cost is reduced.
Description
The utility model relates to a kind of combined type diamond-impregnated wheel, specifically adopts the insert abrading block to constitute the large-scale emery wheel of its effect periphery.Belong to grinding tool.
At present, produce two kinds of technologies of the general employing of large diameter superhard emery wheel, the one, cold pressing---sintering process: after matrix and grinding layer cold moudling, row is fired again.Its shortcoming is that equipment investment is huge, and sintering quality is wayward, and the grinding layer density is low, and product quality is bad, and the small lot batch manufacture cost is higher.The 2nd, the intermediate frequency heat pressing process: at first hot pressing goes out ring-shaped sintered body, and is bonding with matrix again.Owing to adopt hot pressing, be easier to produce the goods of different bonds, grinding layer dense structure, good product quality.But, generally only limit to the following emery wheel of small lot batch manufacture φ 250mm owing to be subjected to the restriction of hot pressing die scantling and cost.
The purpose of this utility model is to overcome problems of the prior art, and a kind of hot-pressing production process that adopts is provided, and is convenient to make super-large diameter product combination formula diamond-impregnated wheel.
The purpose of this utility model is achieved by the following technical solution: a kind of combined type diamond-impregnated wheel that the ablation layer is set on dish-type matrix and its circumferential edge that includes, its matrix is that the center has the rigid disc that axis hole and periphery are provided with the square-section annular groove, is installed with the diamond grinding block of forming the ablation layer by the square-section groove on this disc circumference; Its abrading block radially is provided with forming tank; Be filled with kollag between per two abrading blocks.
The purpose of this utility model also is achieved through the following technical solutions: be provided with axial steady pin at matrix and the abrading block place of splicing.The all side parts of its abrading block external diameter partly are the sintered bodies that adopts different materials to constitute with all sides of internal diameter.
The utility model has the advantages that:
1, owing to adopt combined type emery wheel structure, becomes integral heat pressure and be sintered to branch body unit hot pressed sintering, make the super-large diameter diamond-impregnated wheel adopt heat pressing process production to become possibility, improved the performance and the quality of product greatly.
2, because dwindling of sintered body size suits to adopt cheap miniature resistance directly-heated type sintering machine; And required graphite jig manufacturing cost reduces at double, and unit cost is reduced greatly.
3, because sintered body is a unit abrading block form, be easy to the composite design graphite jig and adopt advanced group technology aborning, make the emery wheel production control in low-cost level, both be suitable for Multi-varieties and Small-batch Production, be suitable for again producing in enormous quantities.
4, fill kollag between abrading block, can reduce the generation of grinding heat, increase emery wheel service life, improve the product to be processed grinding quality.
5, its insert pin fixed structure was removed because of abrading block bonding required curing time, has shortened life cycle of the product, and combined strength and emery wheel precision are improved greatly.
6, the different materials structure of abrading block can reduce the abrading block material cost to greatest extent when satisfying ablation layer hardness and intensity, and is beneficial to insert and fixing.
Accompanying drawing 1 is the utility model front view;
Accompanying drawing 2 is that half sectional view is looked on the left side of Fig. 1.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described: matrix 1 is provided with annular insert groove for the center has the round metal disk body of axis hole on its excircle, this fluted shaft is rectangular to the cross section.Abrading block 2 is like segment, and the outer end is provided with deep-slotted chip breaker, inner band square-section insert convex body.This abrading block is the composite sintered body, and all side parts of external diameter adopt the metal-bonded diamond abrasive material as the ablation layer, and the side part conduct of internal diameter week connects the cheaper copper-based alloy material of matrix adopting price.Insert convex body on the dependence abrading block 2 cooperates with the annular groove on matrix 1 circumference, abrading block is installed on the circumference of matrix 1.During insert, between two abrading blocks, fill graphite or molybdenum bisuphide kollag 3.For increasing abrading block and high base strength, axial fixing pin 4 is set at its joint.Pin 4 can adopt straight pin, also can adopt threaded connecting pin.The abrading block that the utility model also can adopt different abrasive materials to make is installed on the matrix 1, constitutes the emery wheel of alternate different abrasive material abrading blocks.
Claims (3)
1, a kind of combined type diamond-impregnated wheel, include the ablation layer on dish-type matrix and its circumferential edge, it is characterized in that: matrix (1) has the rigid disc that axis hole and periphery are provided with the square-section annular groove for the center, be installed with the diamond grinding block (2) of forming the ablation layer by the square-section groove on this disc circumference, abrading block (2) footpath upwards is provided with forming tank, is filled with kollag (3) between per two abrading blocks.
2, emery wheel according to claim 1 is characterized in that: be provided with axial steady pin (4) at matrix (1) with abrading block (2) place of splicing.
3, according to claim 1 and 2 described emery wheels, it is characterized in that: all side parts of abrading block (2) external diameter partly are the sintered bodies that adopts different materials to constitute with all sides of internal diameter.
