Abstract
The utility model which relates to a portable manual tapper for the metal sheet, consists of a bolt holder, a bottom tapping cutter, a top tapping cutter, a pressure nut and an operating handle, and is characterized in that the bolt holder is in the form of a reversed ''T'' and the bottom tapping cutter, the top tapping cutter and the pressure nut are arranged on the bolt holder respectively. The utility model has the advantages of simple structure, compact configuration, light weight, easy carriage, safe and labor-saving operation and low cost, and can be used to manually tap larger round holes which are flat and smooth. When a crescent cutting edge is used in the utility model, the uniform stress on the earlier cutting edge changes to stress on two points of the crescent cutting edge tips so that the unit pressure intensity rises by 15 times or so while the operating pressure greatly drops accordingly, thereby enabling manual operation.
Description
Utility model relates to the manual hole making drill of a kind of potable metal thin plate.
Sheet metal (≤2mm) perforate is usually with the way of boring, sawing, dashing, cut, cut.Generally speaking, open the aperture drill bit, open the above aperture of diameter 25mm and need use punch ram.Non-standard workpiece is as wanting wide-bore, and particularly erecting bed operation have to be leaned on the way of gas cutting or bradawl head periphery punching line.Though gas cutting is fast, the equipment complexity, workpiece influences sealing joint and installs because of the distortion of ablating.Use the bradawl wide-bore, the aperture forms jagged edge, needs sanding and polishing, and is time-consuming, and the aperture is nonstandard.At present, though there is the electronic hole saw of import (HOLE SAW) of sale drill bit in market, for the thin plate perforate provides a kind of green bit, maximum model has only below the diameter 51mm, still can't solve the problem of large aperture perforate.
The purpose of this utility model is that it provides a kind of simple in structure, easy to carry, safe in utilization laborsaving, with low cost, can be used for out the manual hole making drill of potable metal thin plate of larger caliber.
The purpose of this utility model is achieved through the following technical solutions: it is by screw bolt seat, incision hole cutter, on cut the hole cutter, the pressurization nut, operating grip is formed, screw bolt seat is formed the structure of falling the T-shape by supporting backing plate and screw rod, on screw rod, be provided with the crin screw thread, the upper end of screw rod is provided with locating hole, incision hole cutter and on cut the hole cutter the center be provided with the hole, and be placed on the screw bolt seat respectively, the centre of incision hole cutter has spill garden groove, on cut the hole cutter the centre be provided with the crescent edge of a knife of downward protrusion, the diameter of the edge of a knife is slightly less than the spill garden groove diameter of incision hole cutter, is provided with the pressurization nut on last top of cutting the hole cutter, be provided with on the inner peripheral wall of pressurization nut with screw rod on the internal thread that is complementary of external screw thread, periphery at the pressurization nut is provided with the pressurization hole, and an end of operating grip can be installed in the pressurization hole.
The utlity model has simple in structure, volume is little, advantage laborsaving, with low cost in light weight, easy to carry, safe in utilization, can be used for the manual circular hole of opening larger caliber.After the utility model adopted the crescent edge of a knife, it was stressed to change moon 2 of age of a draught animal points into by the otch average force in past, and the unit's of making pressure increases about 15 times, significantly reduces and operating pressure is corresponding, has created condition for realizing manual operations.This hole making drill is that the sheet metal workpieces of industries such as chemical industry, light textile, food, building decoration, hot-water heating engineering is processed at the scene, the perforate operation in the big or middle aperture in the installation process, provides a cover light practical tool.3 inches pores (diameter 89.5mm) are opened in single bimanualness, only need about 2 minutes time, and the aperture is smooth smooth.This hole making drill also is applicable to the township enterprise of the few electricity of short of electricity, can be widely used in manual punching press, open the following various circular holes of diameter 100mm.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the crescent edge of a knife.
In order to make the utility model structure clear more complete, the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is by screw bolt seat 7, incision hole cutter 6, on cut hole cutter 4, pressurization nut 2 and pressurized handgrip 8 are formed.Screw bolt seat 7 is formed the structure of falling the T-shape by supporting backing plate 71 and screw rod 72, on screw rod 72, be provided with the crin screw thread, the upper end of screw rod 72 is provided with locating hole, incision hole cutter 6 and on cut hole cutter 4 the center be provided with the hole, and be placed on respectively on the screw bolt seat 7, the centre of incision hole cutter 6 has spill garden groove 61, on cut hole cutter 4 the centre be provided with the crescent edge of a knife 41 of downward protrusion, the circular arc of the crescent edge of a knife is its radius with the round diameter of its projection, the diameter of projection is slightly less than spill circular groove 61 diameters of incision hole cutter 6, be provided with pressurization nut 2 on last top of cutting hole cutter 4, be provided with on the inner peripheral wall of pressurization nut 2 with screw rod 72 on the internal thread that is complementary of external screw thread, periphery at pressurization nut 2 is provided with pressurization hole 21, and an end of operating grip 8 can be installed in the pressurization hole 21.
For the resistance of reducing friction, be provided with plane bearing 3 last cutting between hole cutter 4 and the pressurization nut 2.
Upper and lower edge of a knife spacing of cutting between the cutter of hole is the 6-10 silk.Being interspersed with in locating hole can easy-to-mount backstay 1.Above pressurization nut 2, also be provided with and hexagonal (hexagon)nut 22 that the nut 2 that pressurizes fuses.Periphery at the pressurization nut has pressurization hole 21 more than two.
During use, only need the workpiece 5 that has aperture is earlier placed, between the cutter of incision hole, one holds backstay 1; Another holds operating grip 8, and by the screw thread rotation pressurization, makes upper and lower cutting between the edge of a knife of hole produce shearing force, realizes the final purpose of perforate.
