Abstract

The utility model discloses a novel gas cutting tool which can be conveniently used. The utility model is a gas cutting gauge device which is used by matching with a gas welding and cutting handle. The gas cutting gauge is suitable for processing round pieces in container manufacture process and the water heating construction, and the gas cutting gauge is also suitable for cutting flanges and can be used for the opening operation. The gas cutting gauge is composed of a the base of the center of a circle, a shaft bracket, a ruler rod, support wheels and the height adjusting device of the air nozzle of a welding handle. When the gas cutting gauge is used, the size of the radius is adjusted, the permanent magnet base is absorbed on a steel plate, the height of the air nozzle is adjusted, and the fire is fired; simultaneously, the cutting handle is pushed by an operator to run smoothly along the track of the circle to complete one circle of the prescriptive track, and the round pieces can also be processed in the steel plate.

Description

Gas cutting gauge

The utility model relates to a kind of gas cutting tool, particularly a kind ofly can easily center of circle axle bed be fixed (suction) Gas cutting gauge cyclotomy instrument on steel plate, is suitable for using gas welding cutting rounding type workpiece, promptly cuts the system ring flange, expands work such as circular hole.

In producing now, with gas welding system ring flange, when steel plate loading and unloading enlarging, the instrument of use is at need, and is top and pass that the top cross bar that at one end is welded with an iron cover forms.When need on steel plate, cut the method for making orchid, when circular hole is opened in blanking, then at first will rule on steel plate is punched in the center of circle with point and gets ready, then with top downward aligning towards point, with cross bar with the good radius length of dipstick metering, with cutting nozzles portion is inserted in the iron cover of cross bar head, during operation, the people promptly will note top, notes the track of circle again, be also noted that the valve height simultaneously, amount of oxygen, alkynes amount, the control of air door.In the operation, personnel (operator) are very nervous, because top (center of circle), the balance of track, cross bar, the height of valve all will be by operator's Artificial Control, cause tempering, sideslip easily, cause difficulty for the work of gas cutting cyclotomy and result in hand cramps, influence work quality, and manufacturing schedule.

Task of the present utility model is to provide a kind of easy to use, easy-operating novel gas cutting tool, it can be fixed on center of circle axle bed (on the workpiece) on the steel plate easily, scale is determined the length of radius, make and cut handle in the circle track even running of operator's promotion lower edge, cut and make round workpiece, thereby simplified operation sequence, improved quality and efficient.

Task of the present utility model is finished as follows, below circle core shaft, base portion is equipped with a permanent magnet, by its magnetic force center of circle axle bed is fixed on (on the workpiece) on the steel plate, the angle of track support wheel is mixed up, the welding gun valve from the bracket holes of the support wheel front side of top insertion scale head, is adjusted the bracket holes lifting device, find the optimum distance of flame and workpiece.Wind, oxygen supply are given in igniting then, and the track along the Gas cutting gauge regulation promotes to cut handle simultaneously, finishes one week of regulation track, just cuts out round workpiece smoothly.The operator only notes the control of air quantity, amount of oxygen in operating process, thereby has simplified operation sequence, and the operator is freed under the duty of anxiety, removes the many troubles in blanking operation and the operation, only need provide workpiece size during blanking and get final product.It is easy, easy to use that this device is adjusted, and reached the saving of labor, easy, the effect that workpiece is carefully and neatly done.Number of parts and cost cost are not high when the example structure that describes in detail below adopting, processing and manufacturing easily.

Below with reference to accompanying drawing the utility model is described in further detail.

Fig. 1 is the utility model overall structure schematic diagram.

Fig. 2 is along A-A line cutaway view.

Fig. 3 is the cutaway view along the B-B line.

Permanent magnetism base assembly (I) comprising among the figure: 1 magnetic axle bed, 2 central shaft supports, 3 directrix chi card framves, 14 annular permanent magnnets, 15 are led utmost point iron.4 scale bars.Wherein bogie wheel assembly (II) comprising: 5 supporting wheel frames, 6 support wheels, 7 vertical parallel are adjusted knob.Wherein electrode holder guiding mechanism assembly (III) comprising: cover, the rotating interior cover of 11 lifting devices, 12 tommy bars, 13 movable coupling members at the bottom of 8 parallel rods, 9 spacing members, 10 lifting devices.

With reference to Fig. 1, magnetic axle bed (1) with good fixation, make the central shaft support (2) that circumference rotates with the heart therein, directrix chi card frame (3) and the scale bar (4), the support wheel carrier (5) that pass chi card (3), support wheel (6) is adjusted knob (7) with center axle bed vertical parallel, valve lifting device (9), (10), (11) (12), movable coupling member (13) and with support wheel carrier (5) parallel rod (8) and form Gas cutting gauge jointly.Wherein in the magnetic axle bed (1) permanent magnet is housed; Ring-like permanent magnet (14), lead utmost point iron (15).During use by the processing dimension that has provided, adjustment scale bar (4) fixes directrix chi card frame (3) can not go here and there scale bar (4), adjust support wheel and center axle bed and make it vertical parallel, magnetic axle bed (1) is found the center of circle on workpiece, it is the cross hairs of crossing the center of circle on the cross-hair alignment pieces on the axle bed, the magnetic axle bed just can be under the effect of magnetic force, suction (on steel plate) and then the mouth of gas cutting handle inserted lifting device (10) (11) endoporus from the top on workpiece, adjust to promote tommy bar (12) then and make and cut a valve, put down tommy bar (12) owing to being that hinge arrangement just can be sagging naturally with workpiece has a best flame fixed distance.The wind oxygen supply is given in igniting, promotes to cut handle along the track of Gas cutting gauge regulation, finishes one week of regulation track and complete processes round workpiece.

Show as Fig. 2, shown in A-A line cutaway view, chi card (3) can rotate 45 ° up or down in the horizontal direction in the central shaft support (2), and this sample device also can adapt on protruding, concave surface workpiece work such as processing circular hole enlarging.
