Abstract
The utility model relates to a clamping type spiral cutter for hard alloy machines, which is the specified cutter used for dicing cutters for polyester cutting sheets in the chemical fiber industry. A cylindrical cutter body is provided with a plurality of spiral blade grooves, and blades are respectively arranged at both sides of the blade grooves. In the middle of each groove, the blades can be fixedly connected with the cutter body by using screws. The blades are fabricated by hard alloy material, and have the hardness of cutting edge of more than HRC 74 DEG. The utility model has the durability increased two times, replaces imported cutters, saves a large quantity noble metal materials, and reduces the production cost.
Description
The utility model relates to a kind of carbide alloy clip type helical tooth blade, is used in the dedicated tool on the pelleter of chemical fibre industry polyester slice specifically.
Domestic each employed grain-cutter of polyester slice factory mainly is the BARMAG company import that relies on from Germany at present.Domestic part producer makes similar this cutter, does not all reach the level of import cutter in the use, and can not satisfy user's requirement.
The polyester pelletizing dedicated tool that the purpose of this utility model provides a kind of hardness and durability doubles, blade can be changed.
The utility model is to be achieved through the following technical solutions: several strips helical blade groove is arranged on the column type cutter hub, and blade is placed on the both sides of insert groove respectively, and briquetting is used in the centre, blade is tightened up with screw be connected on the cutter hub.
Good effect of the present utility model improves former import Germany cutter, under the prerequisite of the geometric angle parameter constant of former cutter, is import cutter teeth portion originally built-up welding Si Taili alloy, and grinding forming after Overheating Treatment carries out structural change.According to actual needs, as long as the groove of the spiral helicine slotting tool sheet of processing belt on cutter hub, blade can change, and uses Hardmetal materials to make the utility model cutter, its edge hardness can reach more than HRA89～91 degree, and former import Si Taili alloy cutter cutting edge hardness has only HRC50 to spend more.The wearability of cutter improves greatly, and the durable degree of cutter doubles at least.The utility model cutter can more renew blade at any time, cutter hub can be reused, and the import cutter is when using the minimum limit of size, and cutter integral body is all scrapped, so the utility model can be saved a large amount of precious metal materials, reduced the use cost of cutter simultaneously.
Further specify the utility model content below in conjunction with accompanying drawing:
Fig. 1 is the sectional schematic diagram of the utility model structural principle.
Fig. 2 is a kind of of the utility model overall appearance figure.
See Fig. 1, cutter hub 1, blade 2 are to use the Hardmetal materials manufacturing, and blade 2 is inserted in the both sides with spiral helicine insert groove of cylinder cutter hub 1, and the middle briquetting 3 that adopts is fastenedly connected on cutter hub 1 by screw 4.The number of teeth of this cutter has four kinds in 25,30,40,50 teeth etc.It shown in Fig. 1 the sectional drawing of 30 teeth.On its circumference, be processed with 15 helical blade grooves, be processed with several screw holes in the bottom of groove.Blade is made the band spirality, and in order to overcome the cutter centrifugal force in when revolution, blade is made the wedge that falls that has certain angle.During assembling,, respectively lay a slice or several pieces (length according to cutter is determined) blades in the two sides of same insert groove.The briquetting that lay the centre is wedge, tightens up with screw and forms one complete cutter.
Fig. 1 also is most preferred embodiment figure of the present utility model.Be processed with that several screw holes are used for laying and the fixing usefulness of briquetting at the helical blade trench bottom of cutter hub.
