Description

The Diamond strip saw blade

The utility model relates to cutter sweep, is a kind of diamond saw in order to cutting high rigidity building stones.

In the prior art, mostly adopt diamond saw that building stones are processed cutting.The inventor had once applied for to Patent Office of the People's Republic of China that an application number was " structure-improved of diamond saw " utility model patent of 96229548.5 preceding, and its theme is the improvement to the diamond saw blade.In the concrete cutting processing of stone material, the sawing large-stone is mainly used Diamond strip saw blade dragsaw or gang saw, and the problem that has saw blade equally during with this dragsaw or gang saw sawing high rigidity stone material and run into.So existing Diamond strip saw blade also must improve.The defective of existing gang saw, dragsaw is described as follows: at first see also Fig. 5 and Fig. 6, seen that by figure existing diamond gang saw (or dragsaw) A is strip, standard type is about 3.5 millimeters thick of body steel band A1 (T), 180 mm wides (W), 3000 millimeters-6000 millimeters long (L1), its diamond abrasive material piece sawtooth B system is type, is fused on the steel band A leading edge, about 20 millimeters of its length (Z), the about 4-5 millimeter of width (U) is that the perforation A2 at mat gang saw A two is fixed on the buck, uses sawed-off stone material.Generally speaking, the diamond gang saw includes multi-disc Diamond strip saw blade, so that stone material is once become polylith slabstone with regard to sawing.This kind diamond gang saw is when the stone material in the sawing higher hardness, the big arc of the tension force of its steel band Al increases, it is crooked to cause the stone material sawing degree of depth to take place, its typical crooked and round diamond saw is similar, even all conform with requirement in mechanical condition, steel band A1 is hypertonia still, its principal element is to be that hardness of stone is higher, diamond abrasive material piece (being sawtooth B) can produce high hot friction because of hardness of stone is higher when producing relative motion with stone material, steel band A1 inside has been produced compression, make gang saw A produce hypertonia, can't be directly vertical cutting stone material, the slabstone of last gained can't form vertical and.Have, steel band A1 system is with the stone material of deformation direction cutting higher hardness, so the inevitable abrasion deformation of steel band A1 again, and then this steel band A1 use is scrapped soon or pulled down to keep in repair to proofread and correct and handle.

The purpose of this utility model provides a kind of improved Diamond strip saw blade, make it when cutting high rigidity stone material, the straight-cut cell wall that can keep stone material is a constant linearity, to reach the large and small size and the shape of effective control finished product stone material, save raw material, enhance productivity.

The utility model of realizing above-mentioned purpose is, the same substantially with the structure of existing Diamond strip saw blade, in the welding of strip of sheet body steel band lower limb diamond abrasive material piece (sawtooth) is arranged, but suitable position is distributed with several perforation above being positioned at following diamond abrasive material piece on the strip of sheet body steel band in the design, is provided with the column diamond abrasive material that the side is respectively stretched out at two ends in this perforation.This column abrasive material piece is identical with the material of following diamond abrasive material piece.

The lateral length of above-mentioned column diamond abrasive material piece preferably makes it just to equal the width of diamond abrasive material piece down.And, the most handy such as methods such as welding, welding or powerful bondings, column diamond abrasive material and perforation (that is steel band) are combined as a whole.

Structure of the present utility model is from the above mentioned seen, because suitable position distributes and is provided with its lateral length of several piece column diamond abrasive material piece identical with the width of following diamond abrasive material piece (being sawtooth) on strip of sheet body steel band, and, column abrasive material piece is identical with the material of following diamond abrasive material piece, its contact-making surface is also identical, therefore both wear rates equate, increase along with cutting depth, this column diamond abrasive material piece depends on the two cutting cell walls with its two ends, then this column diamond abrasive material piece plays the role of positioning on the one hand, be down that more the stress moment that diamond abrasive material piece is produced can most of be passed on the two side of cutting slot by this column diamond abrasive material piece, the tension force that steel saw blade belt body itself born is reduced, that is saw blade have higher straight-cut and is subjected to force intensity.See that thus basic advantage of the present utility model is the permanent straight degree that can guarantee stone material cutting groove depth direction.The finished product that so processes can guarantee the plate that is processed into, the dimensional accuracy of sheet stone material, thereby guarantee to produce high quality of products in next procedure.In addition, the utility model also has cutting processing efficient height, advantages such as saw blade long service life.

Embodiment of the present utility model as shown in drawings.Below in conjunction with accompanying drawing and embodiment the utility model is specified.

Description of drawings:
