Abstract
The utility model relates to a diamond saw blade for asphalt road, comprising a bit 1, tooth-guarding blocks 2, and a basal body 3. The bit 1 and the tooth-guarding blocks 2 are all formed by heat pressing and sintering diamond particles and metal powders after being mixed homogeneously. The basal body 3 is welded with the bit 1 and the tooth-guarding blocks 2. The tooth-guarding blocks are arranged in groups and each group penetrates into the basal body step by step. A concave platform 3a which is closely adjacent to the tooth-guarding blocks is arranged on the basal body 3. The utility model solves the deficits and defects on the existing diamond saw blade for asphalt road that the service life is short, the bit is easy to be burnt and broken and easy to abscise, the basal body of the saw blade is heavily abraded, saw kerf cutting accuracy is not high, and the production efficiency is low, and provides a diamond saw blade for asphalt road which is long in service life, quick in cutting speed, good in whole performance, high in production efficiency, able to work for a long time, and particularly used for cutting hard and brittle non-metallic materials such as asphalt road with high stickiness because of which the saw blade is not easy to be cooled.
Description
Technical field
The utility model relates to a kind of diamond saw blade, and particularly a kind of welded type pitch road diamond saw blade is specifically designed to cutting vicidity height, and saw blade is difficult for the hard brittle non-metallic materials such as pitch road of cooling.
Background technology
At present; China uses common diamond saw blade road pavement to carry out sawing and maintenance mostly; because pitch and concrete road belong to hard brittle non-metallic material; particularly the pitch road cuts the vicidity height; saw blade is difficult for reasons such as cooling; often take place that saw blade tip burns, cutter head comes off, saw bit matrix serious wear, the not high situation of saw kerf cutting accuracy, therefore cause shut down frequent, saw life is short, labor productivity is not high.The external special asphalt road sheet that adopts uses high output diesel engine to be used as power.Owing in saw blade is produced, use wear-resisting carcass and high strength diamond, make that saw life is longer, cutting is sharper, reduced downtime, improved operating efficiency.But because high strength diamond costs an arm and a leg, carcass and diamond adhesive strength are difficult for grasping, key is can't overcome that saw life is short, matrix is easily worn out, cutter head easily burns, tooth often occurs collapsing, fall technical barrier such as tooth, therefore, the domestic moderate cost of not producing as yet, the special asphalt road sheet of suitable market demand.
The utility model content
The purpose of this utility model is to provide a kind of pitch road diamond saw blade, the life-span is short when having overcome existing diamond saw blade cutting pitch and concrete road, cutter head easily burns, cutter head easily comes off, saw bit matrix serious wear, saw kerf cutting accuracy are not high, deficiencies such as production efficiency is low and defective
The technical solution of the utility model is:, a kind of pitch road diamond saw blade, by cutter head, protect the tooth piece, matrix constitutes, cutter head with protect the tooth piece by metal dust with diamond particles mixes after Thermocompressed sintering and forming, matrix after machining with cutter head, protect the tooth block welding together, protect tooth piece grouping and arrange, every group all is and progressively gos deep into the matrix internal arrangement; Matrix be provided with and protect the tooth piece near concave station.
The beneficial effects of the utility model are: the life-span is short when having solved existing saw blade diamond saw blade cutting pitch and concrete road, cutting is not sharp, cutter head easily burns, tooth often occurs collapsing, fall tooth, matrix is easily worn out, deficiencies such as production efficiency is low and defective, provide a kind of cut sharp, life-span long, matrix is not easy to wear, do not fall tooth, sturdy and durable, special asphalt road sheet that manufacture craft is simple, with short production cycle.Can be specifically designed to cutting vicidity height, saw blade is difficult for the hard brittle non-metallic materials such as pitch road of cooling.
Description of drawings
Fig. 1 is the organigram of pitch road diamond saw blade.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Figure of description is an enforcement optimal way of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
As shown in the figure: pitch road diamond saw blade, comprise cutter head 1, protect tooth piece 2, matrix 3.Cutter head 1 with protect tooth piece 2 by diamond particles with metal dust mixes after Thermocompressed sintering and forming, matrix 3 and cutter head 1, to protect tooth piece 2 welded together, protect 2 groupings of tooth piece and arrange, every group is all progressively goed deep into the matrix internal arrangement, has effectively alleviated the wearing and tearing of matrix 3 in cutting process.Matrix 3 be provided with and protect tooth piece 2 near concave station 3a, strengthened matrix 3 and protected tooth piece 2 weld strengths.
