Abstract
The utility model relates to a high-speed steel shovel drill tool body which comprises a blade part and a handle and is characterized in that the blade part is provided with chip grooves, a blade groove, a locating pin, a screw hole and a transition circle. The high-speed steel shovel drill tool body is provided with two chip grooves; the blade groove is rectangle; the two sides of the blade groove are respectively connected with one chip groove; and the locating pin is matched with the blade. The high-speed steel shovel drill tool body is further provided with an internal cooling passage, wherein the water inlet of the internal cooling passage is arranged on the handle, and the water outlet of the internal cooling passage is arranged on the end face of the blade part. The chip grooves of the high-speed steel shovel drill tool body adopt straight grooves or spiral grooves. The high-speed steel shovel drill tool body has a concise structure and improves the use efficiency, service life and machining precision of the drill.
Description
Technical field
The utility model relates to a kind of five metals machining tool, and particularly a kind of high speed steel shovel of the existing fluted drill of replacement that is applicable to bores cutter hub.
Background technology
The fluted drill specification is all less in the existing market, and big specification employing monoblock type cost can be very high, and wearability and fatigue resistance are relatively poor.Also have few part to adopt high-speed steel and the manufacturing of powder high-speed steel, the more expensive production cost of this type material is bigger.There is following shortcoming in the traditional integral high speed steel twist drill: 1. the processing diameter range is little; 2. machining accuracy is low; 3. the life-span is short.
Summary of the invention
The utility model technical problem to be solved is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of high speed steel shovel to bore cutter hub, improves drill bit service efficiency and service life, improves machining accuracy.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this high speed steel shovel bores cutter hub; Comprise blade and handle; It is characterized in that blade is provided with chip area, insert groove, alignment pin, screw hole and transition circle, the high speed steel shovel bores cutter hub and is provided with two chip areas, and insert groove is rectangle; Each is connected the insert groove both sides with a chip area, and alignment pin cooperates with blade.
The utility model also is provided with inner cooling channel, and the water inlet of inner cooling channel is arranged on the handle, and the delivery port of inner cooling channel is arranged on the blade end face.
The utility model chip area adopts straight trough or helicla flute.
The utility model is simple for structure, improves drill bit service efficiency, service life and machining accuracy.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, present embodiment high speed steel shovel bores cutter hub and comprises blade 1 and handle 2, and blade 1 is provided with chip area 6, insert groove 3, alignment pin 4, screw hole 7, inner cooling channel 5 and transition circle 8.
The high speed steel shovel bores cutter hub and is provided with two chip areas 6, and chip area 6 adopts straight trough or helicla flute;
Usually the type of cooling in adopting, the interior type of cooling be to intake from handle 2, and the orientation is a transition circle 8 at the center, rear end of handle 2 or outside near handle 2, and water outlet can be near insert groove 3 places in blade 1 end face or chip area 6; But also can not adopt the interior type of cooling;
Alignment pin 4 comes the radial position of positioning blade in the insert groove 3;
Screw hole 7 is fixed on the high speed steel shovel through screw with blade and bores on the cutter hub.
The simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought the protection domain that falls into the utility model.
