Abstract
The utility model provides a protecting device for a beam of a large-thickness flame cutting machine. The protecting device comprises a thermal baffle. The thermal baffle is installed on the lower surface of the beam of the flame cutting machine, and specific distance is formed between the thermal baffle and the beam. The protecting device can cover the lower surface of the whole beam. Heat produced during the cutting process firstly reaches the protecting device, so that heat finally reaching the beam can be rapidly reduced, heat is insufficient to enable the beam to be deformed, and can not affect gas pipes and electric wires and cables, and the protecting effect on the beam is achieved.
Description
Technical field
The utility model relates to the NC flame cutting machine field, and particularly relevant for a kind of large-thickness flame cutting machine beam protecting device.
Background technology
Along with Chinese Development in Machine Industry, the demand of steel product is increased severely day by day.Nowadays, the digital control flame plasma blanking has become the indispensable thermal processing method of plate cutting, and big thickness sheet material must rely on the NC Flame Cutting technology.In big thickness steel plate cutting process,, strong pre-heating oxygen and strong cutting oxygen must be arranged, even also V will be arranged on the steel plate that has in order to bore a hole or to cut, X, Y, the cutting of K type straight line groove, must use three cutting torches this moment, is equivalent to again many big thickness flame gun be cut simultaneously, and the heat of generation is quite big.
From cutting theoretically: because cutting process, at first cutting reaches the burning-point of steel, next reaches fusing point, and steel are the violent burning of meeting in oxygen flame stream, and its burning has following several form:
Fe+1/2O
2＝FeO+267KJ
3Fe+2O
2＝Fe
3O
4+1120.5KJ
2Fe+3/2O
2＝Fe
2O
3+823.4KJ
The chemical reaction of these three kinds of burnings all is exothermic reaction, and in the burning, again with Fe
3O
4Account for main component, the heat of flame itself adds the heat of exothermic reaction, has produced very high temperature, and the temperature of cutting steel top is raise rapidly.
With regard to machine frame for movement, because will guarantee the precision of vertical flame lifting, lifting body is no more than 350mm at common stroke, on the following ground of this structure sill from the surface of steel plate height between 350-500mm.The box-structure that crossbeam adopts is subjected to so big temperature, the crossbeam inequality of being heated, can produce distortion to a certain degree, and laterally the guide rail of walking is contained on the crossbeam machined surface, and the distortion of crossbeam can directly have influence on the linearity of cross slide way, thereby the precision of machine is changed.
On the other hand, incisory air supply pipe annex and electric wire all are to go to the crossbeam middle part the trough on the lower plate of box crossbeam, and electrical control cubicles also is directly to be contained in the crossbeam back.Big heat can make tracheae, and the lost of life of electric wire has been brought some potential safety hazards, and electrical equipment also can influence the reliability of use under the high heat environment.The client who perhaps has can adopt the mode of regulator cubicle band industrial air-conditioning to give the Electric Appliance Cabinet internal cooling, and the use of industrial air-conditioning has also increased the operating cost of machine, has produced energy consumption.
Can adopt the mode of steel plate cut surface water spray cooling in the prior art.Yet this mode is the bigger cost that increases machine on the one hand, and the customers' place field conditions has been proposed the consumption that more requirement-----requirement increases the water source and increased water.On the other hand, the steel plate of a part of client cutting needs secondary operations, and surface sprinkling can make cutting steel plate surface hardening, makes the next procedure processing difficulties even can't carry out, and has also increased invisible cost.
Summary of the invention
At above problems of the prior art, the utility model provides a kind of large-thickness flame cutting machine beam protecting device, can cover the lower surface of overall beam.In cutting process; the heat that produces at first arrives the protective device under the crossbeam, and the heat energy of so final arrival crossbeam reduces rapidly, makes this shortage of heat so that beam deformation; can not impact tracheae, electric wire, thereby reach protection effect crossbeam.Concrete technical scheme is as follows:
A kind of large-thickness flame cutting machine beam protecting device comprises thermal insulation board.This thermal insulation board is installed on the lower surface of flame cutting machine beam, and and this crossbeam between have a specific range.
In the utility model, evenly be welded with a plurality of round steel on the described thermal insulation board, thermal insulation board and crossbeam are fixed together by those round steel.
In the utility model, the height of described round steel is 120mm.
In the utility model, the thickness of described thermal insulation board is 3mm.
In the utility model, described thermal insulation board is an iron plate.
The beneficial effects of the utility model are: when the user uses the utility model, can prevent effectively that the heat that produces in the cutting process from making beam deformation, reach the influence that tracheae, electric wire are caused because of heat, thereby reach the protection effect to crossbeam.
Description of drawings
Figure 1 shows that structural representation of the present utility model.
The specific embodiment
For above-mentioned and other purpose, feature and advantage of the present utility model can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.
As shown in Figure 1, large-thickness flame cutting machine beam protecting device provided by the utility model comprises thermal insulation board 10, and this thermal insulation board 10 is installed on the lower surface of flame cutting machine beam 11, and and this crossbeam 11 between have a specific range.Evenly be welded with a plurality of round steel 12 on the thermal insulation board 10, thermal insulation board 10 is fixed together by those round steel 12 with crossbeam 11.
In the utility model, the height of above-mentioned cylinder 12 is 120mm, promptly between thermal insulation board 10 and the crossbeam 11 apart from 120mm.Thermal insulation board 10 can be iron plate, and its thickness is 3mm.
If when flame cuts, when list cuts 100mm with upper steel plate to flame cutting torch cutting 200mm to the flame cutting torch simultaneously with upper steel plate or 2, just need use the utility model, its manufacturing process is:
1, with the inboard weak point 100mm of length of numerical control cutting machine blanking than flame cutting machine two vehicle frames 13, width is identical with the width of crossbeam 11, and thickness is 3mm iron plate 10;
2,6 round steel 12 of even position welding on iron plate 10, the height of each cylinder 12 is 120mm;
3, the iron plate 10 that will be welded with cylinder 12 is done and is joined on the lower surface that is welded in existing crossbeam 11 after surface lacquer is handled.
Aborning, the flame of big thickness steel plate is cut us test, withstood the test of long-time flame cutting, prove that the utility model is effective.
Concrete case study on implementation only is a preferable case study on implementation of the present utility model described in the utility model, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be as technology category of the present utility model.
