Abstract
A mechanical clamping type hard-alloy-tooth circular saw blade comprises a disk-type circular saw blade body. Finished sawteeth are disposed on sheet tooth holders on the tooth tops of sawteeth on the outer periphery of the circular saw blade body. Locating grooves are disposed on the sheet tooth holders. Threaded holes are respectively disposed in the middle of the locating grooves. Locating blocks matched with the locating grooves are disposed at the bottoms of the finished sawteeth. Each finished sawtooth is provided with a stepped through hole corresponding to the threaded hole. The finished sawteeth are respectively installed in the locating grooves on the sheet tooth holders. The finished sasteeth are in fastening connection with the sheet tooth holders through fastening bolts penetrating through the through holes on the finished sawteeth and the threaded holes on the locating grooves. A chemical vapor deposition (CVD) coating layer is arranged on the surfaces of the finished sawteeth. Through adoption of the mechanical clamping type hard-alloy-tooth circular saw blade, the hard-alloy finished sawteeth are mechanically clamped on the tooth tops of the sawteeth, and simultaneously the sawteeth are coated with the CVD coating layer so that the service life of reusing of the saw blade is prolonged and use cost of the saw blade is reduced. Moreover, the saw blade is convenient to assemble and maintain, and does not affect working schedule.
Description
Technical field
The utility model relates to a kind of saw blade that is used for the cutting steel workpiece; Particularly a kind of sawtooth has and adopts connector that the machine card type hard-metal insert saw blade that connects the moulding sawtooth is installed on the toothholder of CVD coating, blade teeth ogival, belongs to metal machining tool field.
Background technology
The hard-metal insert saw blade is in seamless steel pipe, welded tube and rail industry widespread usage; Increase along with steel pipe, rail output; The use amount of hard-metal insert saw blade is also in continuous increase; But along with the grade of steel of pipe, steel pipe, rail product is increasingly high; The life-span of traditional hard tooth saw blade can not be satisfied customer requirements, and its shortcoming is that the cutter piece is directly to be welded on the lamellar body, so diameter can't be taked when excessive feeler block to carry out the CVD coating to handle to improve the measure in sawing life-span.Simultaneously rigidity, intensity, the hardness of the temperatures involved lamellar body during high-frequency welding make lamellar body reuse number of times and reduce.The machine card type saw blade has appearred at present; Though novel machine card type saw blade can solve top problem; But machine card saw-blade structure is very complicated in the market, needs to add the toothing holder on the saw blade excircle again, and processing cost is higher; And specification very minor diameter is many below 500 millimeters, is not suitable in the metallurgy industry large-scale popularization.
The utility model content
The utility model is to the many deficiencies that exist in the prior art, and a kind of machine card type hard-metal insert saw blade is provided.This saw blade one is that to have solved traditional hard-metal insert saw blade low in the sawing high-strength steel life-span, the problem that use cost is too high; The 2nd, solve existing machine card type saw blade complex structure, the problem that processing cost is high.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind of machine card type hard-metal insert saw blade; Comprise discoid saw blade body; On the lamellar body toothholder at the sawtooth crown top of the excircle of saw blade body the finished product sawtooth is housed; Said lamellar body toothholder is provided with locating slot, and the locating slot middle part is provided with screwed hole; The bottom of said finished product sawtooth is provided with the locating piece that is complementary with locating slot, also is provided with on the finished product sawtooth and the corresponding stepped through hole of screwed hole; Said finished product sawtooth is installed in the locating slot on the lamellar body toothholder,, through through hole on the finished product sawtooth and the screwed hole on the locating slot finished product sawtooth and lamellar body toothholder is fastenedly connected with fastening bolt; Described finished product serrated surface is provided with the CVD coating.
Locating slot be shaped as random geometry, said locating piece shape and locating slot shape are complementary.
Compared with prior art; This saw blade disclosed in the utility model is machine card hard alloy finished product sawtooth radially at sawtooth crown position; Sawtooth adopts the CVD coating to handle simultaneously; In single service life in the time of both can having prolonged the high grade of steel workpiece of saw blade sawing, plain steel, can improve again and reuse the life-span.This patent saw blade adopts directly and to be fixed on the simple structure of lamellar body toothholder to the finished product sawtooth with fastening connection pieces such as screws, through can satisfying the quick sawing requirement of various iron and steel and high-strength steel after the special tuning precision, when in sawing process, damaging like the fruit part sawtooth; Only needing to change impaired finished product sawtooth just can continue to use; Not only prolong the repeated use life-span of saw blade greatly, reduced the use cost of saw blade, and be convenient to assembling; Convenient for maintaining does not influence job schedule.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Referring to accompanying drawing 1-6, this machine card type hard-metal insert saw blade comprises discoid saw blade body 1, and the saw blade body is provided with centre bore, driving hole and fabrication hole, and driving hole and fabrication hole are along circle distribution.On the lamellar body toothholder at the sawtooth crown top of the excircle of saw blade body 1 finished product sawtooth 2 is housed, lamellar body toothholder 4 is provided with locating slot 2, and locating slot 2 middle parts are provided with screwed hole 3.Locating slot be shaped as random geometry, like triangle, circle or rectangle etc., finished product sawtooth bottom is provided with the locating piece 8 that is complementary with the locating slot shape.Also be provided with on the finished product sawtooth and screwed hole 6 corresponding stepped through holes 7.Finished product sawtooth 2 is installed in the locating slot 5 on the lamellar body toothholder 4,, through the screwed hole 6 on through hole on the finished product sawtooth 7 and the locating slot finished product sawtooth and lamellar body toothholder is fastenedly connected with fastening bolt 3.Finished product sawtooth 2 promptly is used to the moulding cutter piece that cuts, and its surface is provided with the CVD coating, and this sawtooth tooth depth is higher, transverse tooth thickness is bigger.The thickness of the CVD coating on the finished product sawtooth is 9-12 μ m, and optimum thickness is 10 μ m, and coating is a kind of in TiALN series coating, ALCrN series coating, the TiN series coating.
