CN201033460Y - Node block type diamond circular saw blade - Google Patents

Abstract

The utility model relates to a nodal diamond circular saw blade, comprising a cutter head (1) and a base (2); wherein, the cutter head (1) is nodal; a different-direction sharp corner (1a) is arranged on the top of the cutter head (1); a turbine groove (1b) leading to the top of the different-direction sharp corner (1a) is arranged on the side surface of the cutter head (1); an M-shaped cutting gap (2a) is arranged on the base (2). The utility model has the advantages of solving the problems such as not enough sharpness during working due to no opening of the saw blade top edge, slow heat dissipation of the dry cutting saw blade, high temperature of the base, easy deformation, short service life of the saw blade, long manufacturing cycle, low productivity and serious noise pollution, providing a nodal diamond circular saw blade with high sharpness, durability, long service life, steady production quality, simple processing technology, short manufacturing cycle and high productivity, and being suitable for saw cutting under the conditions of long road and unfavorable water source providing on the concrete and asphalt pavements.

Description

The multi-block type diamond disc

Technical field

The utility model relates to a kind of diamond disc, and particularly a kind of multi-block type diamond disc can be widely used in the sawing of materials such as concrete, bituminous paving.

Background technology

At present, diamond disc is in field extensive uses such as municipal road and bridge maintenance, building, finishings.In the prior art, diamond disc needs out the top sword before sawing, is used to increase the sharpness of diamond disc, but can cause the waste of material like this, and can increase processing cost, and effect is not very desirable; In addition, under existing situation, when adopting the saw blades for dry cutting sawing, saw blade speed is fast, and the workspace belongs to semi-closed state, and heat-dissipating space is little, and the saw blade radiating rate is limited, and the accumulation of heat raises the saw blade temperature rapidly in the short time, has a strong impact on the service life of saw blade.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of sharp more durable, exempt from out the top sword, the life-span is long, cost is low, reduce the multi-block type diamond disc of noise pollution.

The technical solution of the utility model is: a kind of multi-block type diamond disc, comprise cutter head, and matrix, described cutter head is multi-block type, and the cutter head top is provided with incorgruous wedge angle, and the side is provided with the turbine groove that leads to incorgruous wedge angle top, and matrix is provided with the slot of " M " type.

The beneficial effects of the utility model are: solve existing saw blade and exempted from out the top sword, and sharp inadequately during work; The saw blades for dry cutting heat radiation is slow, substrate temperature height, easy deformation, saw life is short, and the manufacturing cycle is long, and production efficiency is low, noise pollution seriously waits not enough, provides a kind of sharp durable, rapid heat dissipation, life-span is long, constant product quality, processing technology is simple, and the manufacturing cycle is short, the multi-block type diamond disc that production efficiency is high can be used for that roads such as concrete, bituminous paving are long-range, the sawing under the unfavorable situation about providing in water source.

Description of drawings

Accompanying drawing is the structural representation of multi-block type diamond disc.

The specific embodiment

Figure of description is an enforcement preferred version of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.

As shown in the figure: the multi-block type diamond disc comprises cutter head 1, matrix 2; Cutter head 1 is mixed after Thermocompressed sintering and forming by metal dust and diamond particles; matrix 2 welds together with cutter head 1 after machining; cutter head 1 is multi-block type; cutter head 1 top is provided with incorgruous wedge angle 1a; the side is provided with the turbine groove 1b that leads to incorgruous wedge angle top, and matrix 2 is provided with the slot 2a of " M " type.

Claims (1)

1. a multi-block type diamond disc comprises cutter head (1), matrix (2); It is characterized in that: described cutter head (1) is multi-block type, and cutter head (1) top is provided with incorgruous wedge angle (1a), and the side is provided with the turbine groove (1b) that leads to incorgruous wedge angle (1a) top, and matrix (2) is provided with the slot (2a) of " M " type.
