Abstract
The utility model discloses a steel plate tapper. The steel plate tapper comprises a central shaft, a twist drill and a tool bit that are coaxially arranged. The twist drill and the tool bit are fixedly mounted on the central shaft, one or more cutting edges are annularly arranged at the front end of the tool bit, the drill bit of the twist drill and the cutting edges on the tool bit face toward the same direction, and the drill bit of the twist drill extends out of the outer sides of the cutting edges on the tool bit. When the steel plate tapper is used for forming holes, the processing size (generally, the size deviation is not larger than 0.5 mm) can be ensured, and the processing size precision is greatly increased. The periphery of the processed hole is smooth and flat, has no burr, and does not need heavy finishing. Through the steel plate tapper, holes can be processed rapidly, regularly, and precisely.
Description
Technical field
The utility model discloses a kind of electromechanical integrated product, particularly a kind of tool for perforating steel plate.
Background technology
Steel plate is the most frequently used raw material in processing industry and the panel beating industry etc., and steel plate is carrying out five metals processing, often need carry out perforate at steel plate.At present, boring method commonly used has two kinds, when the hole of offering hour, can adopt drill bit directly it to be drilled, thereby form an aperture, it only limits to bore dia hour, if opening diameter greater than 20mm, adopts the method for boring, will be difficult to accomplished; Another kind of perforate mode is to adopt the oxyacetylene metal-cutting method of (or claiming gas cutting), promptly be that high temperature with oxygen welding melts steel plate, manual mobile oxygen soldering tip makes it form a hole on steel plate, relatively is applicable to and offers macropore, this kind processing method, not only machining accuracy can not get guaranteeing that the hole dimension deviation is bigger, and deviation is generally in the 2-5 millimeter usually, and can produce irregular batch of cutting edge of a knife or a sword veining defect at the hole periphery, need do and go finishing a large amount of man-hours.
Summary of the invention
Only limit to aperture at the above-mentioned bit bore of mentioning of the prior art, and the bigger shortcoming of oxyacetylene metal-cutting perforate deviation, the utility model provides a kind of hole making drill, can process fast regular again, accurately to portal on steel plate.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of tool for perforating steel plate, hole making drill comprises coaxial central shaft, fluted drill and the cutter head of being arranged on, fluted drill and cutter head are fixedly mounted on the central shaft, cutter head front end annular spread has more than one cutting edge, the drill bit of fluted drill and the cutting edge on the cutter head are towards same direction, and the drill bit of fluted drill stretches out the outside of the cutting edge on the cutter head.
The technical scheme that its technical problem that solves the utility model adopts further comprises:
Described cutter head is fixedly mounted on the knife rest, and knife rest is fixedly mounted on the central shaft.
Described cutter head cross section is annular.
Described cutter head thickness is identical with cutting edge thickness on the cutter head.
Described knife rest is fixedly mounted on the central shaft by screw.
The beneficial effects of the utility model are: when adopting the utility model to carry out perforate, processing dimension is guaranteed, the general size deviation is not more than 0.5 millimeter, and the processing dimension accuracy improves greatly; And the hole periphery that processes, bright and clean smooth, there is not burr to criticize the cutting edge of a knife or a sword defective, need not to do big finishing, perforate processing is fast regular again, accurate.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the utility model decomposing state structural representation.
Among the figure, 1-central shaft, 2-fluted drill, 3-cutter head, 4-knife rest, 5-cutting edge, 6-screw.
The specific embodiment
Present embodiment is the utility model preferred implementation, and other all its principles are identical with present embodiment or approximate with basic structure, all within the utility model protection domain.
Please referring to accompanying drawing 1 and accompanying drawing 2, the utility model mainly comprises central shaft 1, fluted drill 2, cutter head 3 and knife rest 4, in the present embodiment, cutter head 3 and knife rest 4 are fixedly installed togather, and this can adopt modes such as welding, riveted joint to fixedly mount, cutter head 3 front ends are fixed with cutting edge 5, and cutting edge 5 can design one or more, and a plurality of cutting edges 5 evenly distribute ringwise at cutter head 3 front ends.Axle 1 rear end is an installation portion, is used for and drilling machine, milling machine, hand-held fixed installation usefulness such as bore, and central shaft 1 rear end can be circular or square or other are convenient to the shape installing, use, in the present embodiment, is example with square.Central shaft 1 front end is a fluted drill 2, and fluted drill 2 can design with central shaft 1 one, but also split design is fixed together the two by technologies such as welding again.Knife rest 4 is fixedly mounted on the central shaft 1, and in the present embodiment, correspondence has screw hole on knife rest 4 and the central shaft 1, and knife rest 4 and central shaft 1 are fixedly installed togather by screw 6, and the cutting edge 5 on the cutter head 3 and the drill bit of fluted drill 2 are towards a side.In the present embodiment, cutter head 3 is cylindrical, and promptly the cross section of cutter head 3 is annular, and in the present embodiment, the thickness of cutting edge 5 is identical with cutter head 3 thickness, or is slightly larger than cutter head 3 thickness, so that cutting.In the present embodiment, fluted drill 2 length will be longer than cutter head 3 length, and promptly fluted drill 2 has part to stretch out cutter head 3 outsides.In the present embodiment, cutting edge 5 towards to advance to bore direction identical with fluted drill 2.In the utility model, central shaft 1, fluted drill 2 and cutter head 3 coaxial settings.
The utility model is fixedly mounted on the central shaft in the utility model 1 on drilling machine, milling machine or the hand-held brill etc. in use, needs the center of perforate to get final product fluted drill 2 drill bit.During perforate, get an aperture with fluted drill 2 on steel plate earlier, fluted drill is positioned at aperture then, plays positioning action, and then cutter head 3 can be left a circular hole on steel plate.Cutter head 3 diameters are designed to different-diameter, can leave the hole of different-diameter.
When adopting the utility model to carry out perforate, processing dimension is guaranteed, the general size deviation is not more than 0.5 millimeter, and the processing dimension accuracy improves greatly; And the hole periphery that processes, bright and clean smooth, there is not burr to criticize the cutting edge of a knife or a sword defective, need not to do big finishing, perforate processing is fast regular again, accurate.
