Description
Technical field
The utility model relates to steel case beam groove manufacture field, particularly relates to the improved beveling machine of semiautomatic flame cutting machine.
Background technology
Steel case beam is the steel plate box-girder again, is long-span bridge beam version commonly used, uses more and more widely.In the manufacturing process of steel case beam, according to design and code requirement, when two block plates dock, there is thickness of slab poor, bigger in order to prevent stressed variation, cause stress too concentrated, must offer the transition groove on slab, the long minimum of a value of this project gradient is 50mm, and maximum is 272mm, the thickness of slab difference is 10～34mm, traditional processing technology is need carry out mechanical process when transition groove length of grade greater than 80mm, adopts traditional treatment process, and the cycle is long, the expense height, exist secondary to return all too many levels such as factory's processing, therefore,,, be necessary traditional groove processing method is taked corrective measure under the urgent and quality requirement condition with higher in the duration from the angle that reduces cost, to reduce operation intensity, improve whole efficiency.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of improved semiautomatic flame cutting machine is provided, with convenient groove processing to steel case beam, and improves its quality, reduction of erection time, reduce cost.
The technical scheme that its technical problem that solves the utility model adopts is: comprise the semiautomatic flame cutting machine, liquid oxygen jar and the rifle head that link to each other with the band of gas, described rifle head be Numerical control cutting use add the spear head, its length is 450～550mm, and the import cutting torch that links to each other with this rifle head is a divergent contour import cutting torch; Be provided with track, this track slides with the base of semiautomatic flame cutting machine and links to each other.
The utility model compared with prior art has following main advantage:
One. less demanding to equipment, only need conventional equipment, equipment needed thereby is with low cost, use is reliable and light.Simple and convenient, except that adjust the mouth position different with general flame cutting operation, all the other operations substantially with operate equally substantially at ordinary times, veteran gas welder can independently finish the processing to steel case beam groove.
They are two years old. and traditional semiautomatic flame cutting machine can not be processed the groove of length of grade greater than 80mm, one of reason is because the about 700mm of the band of gas that is connected with the rifle head is long, limited the adjustment of rifle brilliance degree, device utilization after the improvement adds the band of gas of spear head and the 2000mm that is connected with the rifle head, has effectively solved the restricted problem of angle adjustment.
They are three years old. and traditional semiautomatic flame cutting machine can not be processed the groove of length of grade greater than 80mm, former therefore two be the cutting the wind line fall short of, when length of grade is longer, or thickness of slab is when thicker, and traditional cutting machine just is difficult to penetrate steel plate, and the device after the improvement utilizes the high pressure canned air to replace pipeline gas, replace conventional gun head and common cutting torch with the divergent contour cutting torch that adds spear head and import, along with the raising of cutting oxygen pressure, therefore the corresponding increase of oxygen flow can increase by cutting plate thickness thereupon.During with common cutting torch gas cutting, under the lower situation of pressure, along with pressure increases, cutting speed also improves, but after pressure surpassed 0.3MP, cutting speed descended on the contrary; Continue intensified pressure again, not only cutting speed reduces, and otch widens, and the otch section is coarse.During with divergent contour cutting torch gas cutting, if cutting oxygen pressure meets the design pressure of cutting torch, when then pressure increases, because the flow velocity of cutting oxygen flow and momentum increase, so cutting speed also increase to some extent than the time with common cutting torch.Utilize rifle head and diffused cutting torch liquid oxygen and lengthening like this, break through the restriction that traditional semiautomatic flame cutting machine length of grade is not more than 80mm at one stroke.
They are four years old. and the groove that utilizes this cutting machine to cut out is smooth smooth, and size is qualified, and every technical indicator all meets code requirement.
They are five years old. can replace the mode of traditional machined groove, can ensure the quality of products, and the reduction of erection time be 1/2nd, reduce cost about 90%.

Fig. 2 is the semiautomatic flame cutting machine 4 among Fig. 1 and the vertical view of matching component thereof.
Fig. 3 is the semiautomatic flame cutting machine 4 of Fig. 1 and the left view of matching component thereof.
Among the figure: 1. the band of gas; 2. add the spear head; 3. electric wire; 4. semiautomatic flame cutting machine; 5. import cutting torch; 6. counterweight; 7. track; 8. liquid oxygen jar; 9. oxygen gauge.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing, but do not limit the utility model.
The utility model provides a kind of improved semiautomatic flame cutting machine, its structure is as shown in Figure 1 to Figure 3: it is by a secondary band of gas 1, one adds spear head 2, a semiautomatic flame cutting machine 4, the import cutting torch 5 of a 603.6#, 25kg counterweight 6, oxygen gauge 9, the propane table, and parts such as supporting power supply are formed.Wherein: liquid oxygen jar 8 links to each other with oxygen gauge 9, and oxygen gauge is linked to each other with semiautomatic flame cutting machine 4 by the band of gas 1, semiautomatic flame cutting machine 4 by the band of gas 1 with add spear head 2 and link to each other.Semiautomatic flame cutting machine links to each other with power supply by electric wire 3, and the base of this cutting machine can be equipped with the vertical pipe of carrying gas at track 7 back and forth movements on the base, and this conduit upper is equipped with a cross bar, and this cross bar one end is installed and added the spear head.Import cutting torch 5 is a divergent contour import cutting torch, its with add the spear head and link to each other.Counterweight 6 is installed on semiautomatic flame cutting machine 4 equipment.
The described spear head 2 that adds adopts Numerical control cutting rifle head, and its length is 450～550mm, generally adopts 500mm.The supporting with it band of gas 1 general lengthening band of gas that adopts 2000mm.
Core of the present utility model is exactly to replace traditional rifle head with adding spear head 2, import cutting torch 5 replaces traditional common cutting torch, utilize high-pressure liquid oxygen in the liquid oxygen jar 8 to replace oxygen in the gaseous mixture pipeline, fall short of the conditional defective of angular adjustment thereby solve a conventional gun wind line.
The course of work of the present utility model is:
1. preoperative preparation:
