Abstract
The utility model discloses a kind of diamond disc that protects tooth piece cutter head with entirety, comprise diamond segment and matrix, matrix border is provided with multiple toothed segment, between each toothed segment, chip pocket is set, the L-shaped joint of diamond segment is block, comprise that the A part of diamond segment is welded on the side, edge of described sawtooth with the A part of matrix welding with as the B part of protecting tooth piece, the B part of diamond segment abuts against on the side of chip pocket.The utility model protects the diamond segment of tooth piece by joint lump zone is set in matrix outer rim; effectively protect the weld seam between cutter head and matrix; prevent that the material corrosion weld seam such as process medium pitch and fresh concrete that cuts road surface from causing cutter head to come off, and effectively extended the application life of whole saw blade.
Description
Technical field
The utility model relates to a kind of cutting tool, refers in particular to a kind of diamond disc that protects tooth piece cutter head with entirety, can be widely used in the cutting of the abrasiveness such as fresh concrete, pitch material.
Background technology
At present; China is used common diamond saw blade road pavement to carry out sawing and maintenance mostly; because pitch and concrete have very strong abrasiveness; particularly asphalt road cutting viscosity is high; saw blade is difficult for cooling; often occur that saw blade tip burns, cutter head comes off, saw bit matrix serious wear, the not high situation of cutting accuracy, therefore cause shutting down frequent, saw life is short, operating efficiency is not high.Therefore, provide the saw blade of a kind of applicable cutting pitch and rigid pavement necessary.
Chinese patent literature ZL200320100704.3 discloses a kind of diamond saw blade for asphalt road, comprises matrix, cutter head and protects tooth piece.Matrix is in the form of annular discs, matrix outer rim is arranged to zigzag, cutter head and protect tooth piece and mix by diamond particles and metal dust after through Thermocompressed sintering and forming, cutter head and protect tooth piece and weld with matrix respectively, cutter head is welded on the outer rim side of matrix, protects tooth block welding on the concave station side of chip pocket side setting.Although the weld seam that the utilization of the structure of this saw blade has been protected tooth block protection between cutter head and matrix, avoids operation process medium pitch and fresh concrete directly etching weld seam, holds caducous problem thereby overcome cutter head.But be to be also connected with matrix by the mode of welding owing to protecting tooth piece, still there is weld seam, and protecting tooth piece is that lower end is welded on the concave station side of chip pocket side, the upper end of protecting tooth piece is to be close on the end face of cutter head, that is to say to protect between tooth piece and cutter head and have gap, in the process on cutting road surface, because diamond disc is perpendicular to road surface, clockwise rotate cutting road surface, the material such as pitch and fresh concrete can enter in this gap, corrode cutter head and protect tooth piece, the weld seam that protects tooth piece place also can be by continuous corrosive wear, attenuate, occur possibly protecting the fracture of tooth piece or coming off, thereby shorten the application life of diamond saw blade, and cutter head and protect tooth piece and need to distinguish after sinter molding integrally welded with matrix respectively again, complex process.
Utility model content
The utility model technical issues that need to address are to provide that a kind of technique is simple, the high strength band of long service life protects the diamond disc of tooth piece.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
A kind of diamond disc that protects tooth piece cutter head with entirety, comprise diamond segment and matrix, matrix border is provided with multiple toothed segment, between each toothed segment, chip pocket is set, the L-shaped joint of diamond segment is block, comprise that the A part of diamond segment is welded on the side, edge of described sawtooth with the A part of matrix welding with as the B part of protecting tooth piece, the B part of diamond segment abuts against on the side of chip pocket.
Further improvement of the utility model is: described matrix is discoid, and the periphery of disk is arranged to the toothed segment that shape is identical.
Further improvement of the utility model is: the A part medial surface of the outer rim of each toothed segment and diamond segment matches; The medial surface of the side of described chip pocket and the B of diamond segment part matches.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is as follows:
The utility model protects the diamond segment of tooth piece by joint lump zone is set in matrix outer rim; effectively protect the weld seam between cutter head and matrix; prevent that the material corrosion weld seam such as process medium pitch and fresh concrete that cuts road surface from causing cutter head to come off, and effectively extended the application life of whole saw blade.
Diamond segment of the present utility model is to adopt integrated diamond segment, and intensity is better, more durable.In the process on cutting road surface, diamond disc clockwise rotates, and cutter head is met to cutting road surface, protects tooth piece part and has protected well the weld seam between cutter head and matrix, pitch, cement bits etc. are not easy to enter weld seam, thereby have avoided being corroded due to weld seam the phenomenon that causes cutter head to come off; In addition, meet to cutting process in, this integrated cutter head, become cutter head part of the whole participation cutting owing to protecting tooth piece, increase effective cutting area of cutter head, therefore the be worn speed of corrosion of the cut surface that has delayed to a certain extent cutter head, has extended application life of cutter head.
Diamond segment of the present utility model is to adopt integrally sintered technique, carries and protects tooth piece, has simplified cutter head and has protected the tooth piece operation of making separately.Owing to only the A part of diamond segment need being welded on matrix, and only need abut against chip pocket inner side as the B part of protecting tooth piece, therefore on matrix, do not need that positioning welding is set again and protect the concave station of tooth piece, thereby simplify the manufacture craft of matrix, also saved matrix and the welding sequence that protects tooth piece.
The A part medial surface of the sawtooth outer rim in the utility model on matrix and cutter head matches, and makes the weld seam of welding more firm; The side of chip pocket and the B of cutter head part inner side matches, and makes as the B part of protecting tooth piece closelyr with matrix laminating, has strengthened the intensity of whole diamond disc, effectively extends the application life of diamond disc.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is done further to describe in detail:
A kind of diamond disc that protects tooth piece cutter head with entirety, as shown in Figure 1, comprise matrix 2 and diamond segment 1, matrix is in the form of annular discs, the outer rim of matrix is evenly arranged to zigzag, and size and the diamond segment of sawtooth match, and chip pocket is set between sawtooth, diamond segment comprises with the A part of matrix welding with as the B part of protecting tooth piece, as shown in Figure 2.The A part medial surface of the outer rim of the each toothed segment on matrix and diamond segment matches, and A part is welded as a whole with the sawtooth of matrix outer rim; The medial surface of the side of the chip pocket between sawtooth and B part matches, and B part abuts against on the side of chip pocket.In operation process, diamond disc, perpendicular to road surface, clockwise rotates, and cutter head is met to cutting road surface, has played well the effect of protection weld seam as the B part of protecting tooth piece.Owing to having as the protection of B part of protecting tooth piece; the material such as pitch and fresh concrete can not contact and corrode easily weld seam; avoid diamond segment to come off from matrix, effectively protected cutter head and matrix, extended the application life of whole diamond disc.
