Abstract
The invention discloses plasma cutting compasses. The plasma cutting compasses are characterized by comprising a nut (1), a bolt (2) penetrating through the nut and a handle (5), and a through hole is formed in the lower end of the bolt; a supporting rod (3) penetrates through the through hole, and a circular ring (4) is arranged at the end of the supporting rod; a supporting point at the bottom of the bolt is arranged to be in an inverted conical shape (7), and a gasket (6) is arranged between the supporting rod and the nut (1). The plasma cutting compasses solve the problems which cannot be solved by a traditional tapping method, the smoothness degree of the tapping edge is effectively ensured, the working period is shortened, the obvious technical effects and economic benefits are achieved, and the plasma cutting compasses are suitable for cutting round holes of various sizes.
Description
Technical field
The present invention relates to a kind of cutting tool, particularly relate to a kind of plasma cut compasses.
Background technology
The method that the airduct lifted is opened circular hole is first finish line with compasses on traditional method, then cuts open along the line with a chainsaw, but there is the drawbacks such as operation is slow, precision is not easily held, perforate is not round and smooth in work progress.
Innovation and creation content
For above problem, inventor is through constantly test and improvement, and design completes the simple cutting tool practical again of structure.Technical problem to be solved by this invention is just to provide a kind of cutting tool, especially provides a kind of plasma cut compasses, overcomes the above-mentioned shortcoming that method operation is slow, precision is not easily held, perforate is not round and smooth opening circular hole on the airduct lifted.
Technical problem to be solved by this invention is achieved through the following technical solutions:
A kind of plasma cut compasses, comprise nut, bolt through this nut, described bolt bottom is provided with perforation; Pole is through this perforation, and described strut ends is set to annulus, can be used for known cutting gun, is especially fixedly applicable to all metal hand-held plasma cutting gun heads; Pad is provided with, for fixing pole between described pole and nut.
Described nut is also provided with a handle, for hand steered handled easily;
The bottom support point of described bolt is set to back taper, when the stud base of back taper ensure that welding cutting, can circumferentially rotate as the pole of drawing radius of a circle;
Described pole is the metal materials such as iron wire material, facilitates end to be made into circular.
The present invention has following Advantageous Effects:
1. adopt bolt, nut, pad, these simple parts of iron wire and material can make plasma cut compasses, tool making is simple, quick, gathers materials on the spot.
2. tap operation is simple and practical, one-shot forming.
3. the limit, hole of this plasma cutting compass cutting is round and smooth, does not have burr.
4. by regulating the length of described pole, the circular hole of convenient cutting various sizes.
5. this use plasma cut compasses, substantially increase construction working efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Detailed description of the invention
A kind of plasma cut compasses as shown in Figure 1, comprise nut 1, bolt 2, handle 5; Pole 3 is through the perforation of described bolt bottom, and described strut ends is set to annulus 4; Pad 6 is provided with for fixing pole 3 between described pole and nut.Described nut is fixed with handle 5; The bottom of described bolt is back taper 7, when the stud base of back taper ensure that welding cutting, can circumferentially rotate as the pole 3 of drawing radius of circle.
During operation, inserted in annulus 4 by the cutting head of cutting torch, another hand steered handle 5, utilize the back taper form point of described stud base, pole 3 can circumferentially be rotated, so achieve cutting compass to open circular hole on the airduct lifted.
The present invention uses in conjunction with plasma cutting gun, and the cutting speed of plasma cutting gun especially can be made faster, and precision is higher, and otch is more level and smooth, and is applicable to all metals.
The invention solves and adopt the unavoidable difficult problem of traditional boring method; Effectively ensure that the round and smooth degree of verge of opening; Save the duration, there is remarkable technique effect effect and economic benefit.
Trial run situation is indicated: ion cutting compass is owing to making simple, simple operation, and application in the airduct processing of Tianjin city square project is on probation, substantially increases the operating efficiency of construction.
The present invention is applicable to the circular hole cutting of various sizes.
Claims (5)
1. plasma cut compasses, is characterized in that: comprise nut (1), bolt (2) through this nut, described bolt bottom is provided with perforation; Pole (3) is through this perforation, and described strut ends is set to annulus (4).
