Welding formula high speed steel planer tool, its welding process influence cutter body material performance, reduce the hardness of material, in case the tool bit wearing and tearing can not reach the machining requirement, the cutter arbor will be useless with the tool bit in the lump, and high speed steel cutter is the most extensive consumptive material of machining trade application, and the cutter arbor is bulky, has caused huge material waste and economic loss in the past in this long time. The high-speed steel planing tool made of W18 and M2 has unsatisfactory tool hardness and wear resistance, and especially when processing difficult-to-process materials such as high-temperature alloy, high-manganese steel, heat-resistant steel and the like, the tool hardness and impact toughness cannot meet the processing requirements, so that the tool consumption cost is increased. Therefore, the cutter head is detachable and replaceable, and the cutter rod can be repeatedly used; meanwhile, a novel high-speed steel tool with excellent cutting performance and a tool body with a unique design can be selected according to the characteristics of a processing material, and is particularly important.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the above-mentioned prior art and not enough, the utility model provides a novel high-speed steel cutter with disposable machine presss from both sides blade.
In order to achieve the above object, the utility model provides a following technical scheme:
novel high-speed steel cutter with disposable machine presss from both sides blade, including cutter arbor, cutter body and the lever subassembly of step up of installing on the machining equipment, the cutter body is the square structure, and cutter body middle part is equipped with the mounting hole, and the cutter body front end is equipped with two sets of main cutting edges, and every main cutting edge's rake is 18, and main cutting edge's knife tip radius is 1.5mm, the cutter arbor under on the terminal surface be equipped with and compress tightly the arch, the cutter body through the lever subassembly of step up with compress tightly protruding cooperation install in the lower extreme department of cutter arbor.
Furthermore, the lever type clamping assembly is composed of a compression screw, an L-shaped compression rod and a compression gasket, the L-shaped compression rod is located in an L-shaped cavity at the lower end of the cutter bar, the short end of the L-shaped compression rod penetrates through the compression gasket and the mounting hole and then is connected with the cutter body, when the compression screw is screwed, the long end of the L-shaped compression rod is stressed and then the short end tilts to form a lever structure, and the cutter body is fastened after being close to the compression protrusion.
Further, when the cutter body is fastened by the lever type clamping assembly, the edge inclination angle of the main cutting edge is-3 degrees, the main deflection angle is 60 degrees, the main relief angle is 6 degrees, and the auxiliary relief angle is 3 degrees.
Further, the cutter body is made of high-cobalt, high-vanadium and powder metallurgy high-speed steel materials.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses cutter wide application is equipped the manufacture trade, can be applied to dig such as shaper, planer-type machine, slotting machine and inserts type equipment, through lever clamping components with high-speed steel cutter body positioning in the cutter arbor bottom, whole cutter body is installed and to be used on machining equipment. When the cutter body is worn and cannot be used, only the cutter body needs to be replaced. The price of the welding plane cutter is about 120 yuan/handle, the utility model discloses the cutter body is 18 yuan cutter arbor repeatedly usable only. Under the same condition, the durability value (about 100 hours) of each welding type plane cutter is equivalent to 2.5 machine clamping type cutter bodies (the durability value is about 40 hours), and 6570 Yuan/handle can be saved by using the utility model in the working time of one year.
