Abstract
The utility model relates to a drill bit technical field specifically is a quick chip removal structure of steel sheet drill bit, should be able to adapt to the BTA of steel sheet drill bit, has simple structure moreover, convenient operation's technical characterstic. The utility model provides a quick chip removal structure of steel sheet drill bit which characterized in that: quick chip removal structure is located the cutter portion of drill bit main part, including chip groove, groove and breach, wherein, a plurality of spiral helicine chip grooves have evenly been seted up to the outer wall of cutter portion, and chip groove from the front end ranging back of drill bit main part, the front end of every chip groove are seted up jaggedly, and the front end system of chip groove is favorable to the groove of chip removal, the groove outwards extends from the bottom slope of breach.
Description
Technical field
The utility model relates to bit technique field, specifically a kind of quick chip discharging structure of steel plate drill bit.
Background technology
Steel plate drill bit is one of common drill bit, be usually divided into spiral bit and core drill first two, be mainly used in punching to sheet metals such as steel plate, section bar, aluminium alloy plates, be generally arranged on drilling machine and support the use.Existing steel plate drill bit, the general drill main body adopting tubulose, the end around drill main body is evenly arranged several cutters, and the center of drill main body is with a little fluted drill.The defect of this type of drill bit is that the length of drill main body is shorter, and chip discharging structure is unreasonable, therefore the sheet metal of 2 ~ 10mm can only be processed, for thick steel plate, applicant proposes a kind of new hollow steel plate drill head, this steel plate drill bit has good length, can deep hole processing, the design but the chip discharging structure of this steel plate drill bit is still needed.
Utility model content
The technical problems to be solved in the utility model is the deficiency overcoming above-mentioned background technology, provides a kind of quick chip discharging structure of steel plate drill bit, should be able to adapt to the deep hole machining of steel plate drill bit, and it is simple to have structure, easy to operate technical characterstic.
The technical solution adopted in the utility model is: a kind of quick chip discharging structure of steel plate drill bit, is characterized in that: described quick chip discharging structure is positioned at the cutter part of drill main body, comprises chip area, groove and breach; Wherein, the outer wall of cutter part evenly offers some spiral helicine chip areas, and chip area extends back from the front end of drill main body, and the front end of each chip area offers breach, the front end of chip area is shaped with the groove being beneficial to chip removal, and described groove stretches out from the bottom angled of breach.
As preferably, the angle of the cross section of described groove and drill main body is 30 ~ 60 degree.
The beneficial effects of the utility model are: chip area of the present utility model is helical form, can adapt to the chip removal under the larger degree of depth, and in addition, the front end of chip area arranges groove, enters chip area again, accelerate chip removal further after being beneficial to metal fragment prebuckling; Therefore the utility model adapts to the deep hole machining reaching 100 ~ 180mm, and its perforate degree of depth is far longer than the chip area of existing steel plate drill bit, and structure is simple, easy to operate.

Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is the sectional structure schematic diagram of Fig. 1.
Fig. 3 is that enlarged drawing is looked on a left side for steel plate drill bit.
Fig. 4 is the perspective view of steel plate drill bit.
Detailed description of the invention
The utility model is described in further detail below, but the utility model is not limited to following examples.
As shown in Figure 1, Figure 2, Figure 3 shows, the quick chip discharging structure of a kind of steel plate drill bit described in the utility model, described quick chip discharging structure is positioned at the cutter part of drill main body 1, comprises chip area, groove and breach; Wherein, the outer wall of cutter part evenly offers some spiral helicine chip areas 3, and chip area extends back from the front end of drill main body.The front end of each chip area offers breach 6, and the left side of breach utilizes silver wire to be welded with cutter 5.The front end of described chip area is shaped with the described groove 4 being beneficial to chip removal, and groove stretches out from the bottom angled of breach.The angle of the cross section of described groove and drill main body is 30 ~ 60 degree.
As shown in Figure 3, Figure 4, the front end of steel plate drill bit is described cutter part, and rear end is clamping part 2, and cutter front end protrudes from the front end of drill main body, and cutter front end is high outside and low outside inclined-plane 5-1.Every two of each cutter is one group, and the outer end, inclined-plane of one of them cutter is shaped with scarf 5-2, and the inner, inclined-plane of another cutter is shaped with scarf.In Fig. 3, the front end of drill main body is provided with four cutters, and in actual applications, the quantity of cutter can be determined as required, such as, arrange six cutters (totally 3 groups).
Finally, it should be noted that the utility model is not limited to above embodiment, a lot of distortion can also be had.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed in the utility model, all should think protection domain of the present utility model.
Claims (2)
