Abstract
The utility model discloses an oxygen melting stick, which comprises a long steel pipe and a short steel pipe which are mutually sleeved, wherein six steel wires are arranged in a hollow cavity of the long steel pipe, and a groove which is projected to the inner wall is arranged on the short steel pipe. The short steel pipe of the oxygen melting stick which is provided by the utility model can immediately generate high temperature of 3600 degrees under the condition that oxygen supports combustion, and the components (metal, non-metal, concrete and rock) which are processed can be rapidly melted or cleaned to achieve the purpose of operating. The effect of the oxygen melting stick can be increased by 4 to 5 times compared with a common oxygen melting stick, the thickness of cutting components can reach more than 1000 mm, and the thickness of cleaning and piercing holes is not referred.
Description
Technical field
The utility model relates to a kind of casting cleaning parts, relates in particular to a kind of oxygen melting bar.
Background technology
Foundry goods in process of production, the surface has a large amount of scab, or one jiao stays rising head.Methods of OFC-A is generally adopted in the removal of casting pressing port, and residual scab then is difficult for removing with Methods of OFC-A.The method of the residual scab of general cleaning is to charge and attack or cut off with gas cutting with pneumatic hammer.Yet, under the residual more situation of scab, adopt said method, require a great deal of time and financial resources, and may not necessarily remove clean.
Oxygen melting bar claims oxygen blast rod or oxy-arc fusing rod again, has fast fast thawing and cuts, functions such as cleaning, oxygen combustion-supporting down, can produce high temperature immediately, make that processed workpiece (metal, nonmetal, concrete, rock etc.) is molten rapidly to be cut or clear up, reach the purpose of operation, be particularly suitable for mobile operating.
When foundry goods (particularly stainless cast steel part) scab, gas cutting is difficult to cut off scab, sanding machine also can't resolve problem, oxygen melting bar can be easy to cut off, because special steel are arranged in the oxygen melting bar pipe, after gas cutting ignited oxygen melting bar, oxygen melting bar began fusing, carry out the very fast embrittlement in oxidation reaction scab position with sand, cutting casting pressing port also is as a same reason.
Summary of the invention
The utility model provides a kind of and has been connected firmly, and good seal performance can effectively prevent the oxygen melting bar that leaks gas.
A kind of oxygen melting bar comprises the long steel pipe and the short steel pipes that socket-connect, is provided with 6 steel wires in the cavity of long steel pipe, and short steel pipes is provided with the groove to the inwall projection.
Groove blocks long steel pipe, makes that being connected of long steel pipe and short steel pipes is more firm.
The outside wall surface of short steel pipes is provided with 2 annular slot rollings, during use and the oxygen access tube form and to be tightly connected, prevent the oxygen leakage that feeds.
The internal diameter of long steel pipe is 9～14mm, and the internal diameter of short steel pipes is 14～20mm.
The length of long steel pipe can is longer than or be shorter than to the length of steel wire, is preferably equal.
The oxygen melting bar short steel pipes that the utility model provides be as long as down can produce the high temperature of 3600 degree immediately the combustion-supporting of oxygen, makes that processed workpiece (metal, nonmetal, concrete, rock) is molten rapidly to be cut or clear up, and reaches the purpose of operation.The effect of oxygen melting bar can improve 4～5 times than common effect, and the thickness of fusion cutting workpiece can reach more than the 1000mm, and cleaning is no matter the thickness of perforation.
The oxygen melting bar that the utility model provides can operation in water medium severe environment, and applied range is easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model oxygen melting bar;
Fig. 2 is an oxygen melting bar A-A profile shown in Figure 1;
Fig. 3 is an oxygen melting bar B-B profile shown in Figure 1.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of oxygen melting bar comprises long steel pipe 1 and short steel pipes 2.Long steel pipe 1 is socketed in the inner chamber of short steel pipes 2, and the internal diameter of wherein long steel pipe 1 is 9～14mm, and the internal diameter of short steel pipes 2 is 14～20mm.
Be provided with in the inner chamber of long steel pipe 1 with tangent 3,6 steel wires of 6 steel wires of long steel pipe 1 inwall between tangent rings take up and suffer, its length is consistent with the length of long steel pipe 1.
The outside wall surface of short steel pipes 2 has the annular slot rolling 4 of two vertical and short steel pipes 2 axis, and feasible long steel pipe 1 and short steel pipes are tightly connected, and can effectively prevent oxygen leakage.
Also have on the short steel pipes 2 to the annular groove 5 of inwall projection perpendicular to the short steel pipes axis, when long steel pipe 1 is socketed on short steel pipes 2, groove 5 can tighten long steel pipe 1 owing to cave inward, and feasible long steel pipe is connected more solid with short steel pipes.
When using oxygen melting bar, only need one of oxygen generator is terminated at an end of oxygen melting bar short steel pipes 2, at an end points fire of long steel pipe 1.Under comburant oxygen, the burning of various elements makes processing work surface produce the above high temperature oxy-arc of 3500 degree, makes processing work finish other means be beyond one's reach cutting or fusing.
