CN2150029Y - Combined saw-blade basic element - Google Patents

Abstract

The utility model relates to a combined saw-blade basic element for cutting stone materials. The basic body of the saw blade forms a laminated construction by a plurality of layers of basic sheets, namely, a novel saw-blade basic body which is composed of a plurality of layers of basic sheets. The inner stress of the basic body can be decreased or eliminated; the integral strength can be increased; the technological performance can be improved; the application range is wide. The utility model not only can produce the saw blade with general size specifications, but also can produce the series saw blade with the diameter more than 300 mm to 4000 mm. The economy is good; the thickness of the basic body can be correspondingly reduced 20-23%; the requirement to the material is decreased; the input material of diamond tool bits can be saved about 20%; the stone material can be saved 10%; the cost can be reduced.

Description

Combined saw-blade basic element

The utility model relates to a kind of cutter member of cutting building stones.

The saw blade that is used for the cutting of marble, granite and so on building stones at present, mainly comprise cutter head and matrix two large divisions, cutter head is the diamond member, the monolithic whole round member that matrix is mostly made for manganese steel, have bit-withdrawing slot on it, and install and to use centre bore, cutter head to be welded in the high-frequency welding method on the circumferential periphery of matrix to constitute.The weak point of this conventional blade is: 1, range of application is restricted, and matrix is carried out modified when waiting heat treatment, and the integral basis body is difficult for evenly everywhere, and internal stress is bigger, can't produce saw blade more than the ∮ 2000mm by present manufacturing process, and limitation is arranged; 2, less economical, be proof strength, the cutter head of this saw blade and matrix all need be made thicklyer, cause valuable diamond segment, that the manganese steel matrix all consumes material is more; And resistance is big during work, and the wearing and tearing of saw blade and device are also big, and operating efficiency reduces, and energy consumption is many; When cutting building stones in addition, building stones consumption is also big; Cost height, material resources waste.

The purpose of this utility model is to avoid weak point of the prior art, and a kind of scope of application is wide, the combined type saw bit matrix product of good economy performance and provide.

Can take following technical scheme to realize purpose, make matrix which floor substrate constitute laminated construction, be i.e. the novel saw bit matrix that combines of multi layer substrate by.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is a kind of structure front view of this combined type saw bit matrix;

Fig. 2 is the A-A cutaway view of Fig. 1.

But cutter head 1 part and the prior art of this saw bit matrix adapted do not have difference, and it is the diamond member, and it can adopt the cutter head goods of different shape structure, the circumferential periphery place of welding or being installed on matrix.

Matrix 2 parts are the laminated construction that are made of which floor thin substrate 3, and the material of substrate can be thin manganese steel, middle carbon, cold rolling and other sheet metal, and sheet metal thickness selects to use the specification requirement that can satisfy various saw blades between 0.5-4mm.The substrate number of plies that constitutes matrix can be according to the situation of building stones, and factors such as saw blade diameter are taken the circumstances into consideration selected, and general 3-8 layer gets final product, and every layer of substrate member can be the full wafer round member, also can be two cyclotomy, three cyclotomy ... the member that is combined into.The substrate on top layer adopts the full wafer round member to be advisable, and intraformational bed can be with full wafer, also can be combined into.The mode of combination can be taked riveted joint, be gluedd joint and welding between substrate, comprises modes such as spot welding, roll welding, and bit-withdrawing slot and installation centre bore also should be arranged on the matrix.

Matrix 2 in the accompanying drawing institute example is the laminated construction that adopt three above medium carbon steel substrate 3 spot welding to constitute, its intensity height and integral thickness is thin.

The relative prior art of the technical program has following advantage:

1, by the combination of multi-disc lamination, reduce or eliminated the internal stress of matrix, its bulk strength improves, and improves technical performance;

2, the scope of application is wide, because matrix is not subjected to the restriction of sheet metal size and other process conditions, except the saw blade that can make the stock size specification, also can make the above serial saw blade of ∮ 300-∮ 4000mm;

3, good economy performance: lamination makes up the corresponding attenuate 20-23% of the comparable former full wafer matrix thickness of matrix, and the material of matrix is required to reduce, and can adopt the general steel manufacturing of medium carbon steel and so on; The diamond segment materials can be saved about 20% relatively, and the cost of cutter, cost reduce; Saw blade has approached, and working resistance is little, and cutting speed is accelerated, and the wearing and tearing of cutter and equipment self, energy consume corresponding reducing, and work efficiency improves; Also can save stone material 10%.

Claims (2)

1, a kind of combined type saw bit matrix, it is a round member, it is characterized in that: it is the laminated construction that is made of which floor circular substrate 3.

2, saw bit matrix as claimed in claim 1 is characterized in that: matrix is the laminated construction that adopts three above medium carbon steel substrate 3 spot welding to constitute.
