Detailed Description

The features and properties of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

It should be noted that, the size of the iron powder through pipe should be set according to the actual working condition, and the iron powder through pipe is too thin to meet the requirement of iron powder blowing amount, and the iron powder through pipe is too thick to waste materials. Therefore, the position adopts a certain actual size, namely the length is 80mm, the outer diameter is 10mm, and the inner diameter is 5 mm.

Example 1

This embodiment is used for explaining the present invention specifically.

As shown in fig. 1 and 2, the novel hand cutting torch for cutting stainless steel square billets of the present invention comprises a cutting torch, wherein the cutting torch comprises a mixed gas pipe 4, a cutting oxygen pipe 5 and a cutting torch 7, one end of the mixed gas pipe 4 and one end of the cutting oxygen pipe 5 are respectively provided with a preheating oxygen valve 1, a cutting oxygen valve 2 and a gas valve 3 for control, and the other end is connected with the cutting torch 7; still include iron powder siphunculus 6, iron powder siphunculus 6 sets up on the burning torch to the one end of iron powder siphunculus 6 is buckled, makes the mouth of pipe of the end of buckling of iron powder siphunculus 6 aim at cutting torch 7.

The hand cutting gun further comprises a pipe clamp 8, and the iron powder through pipe 6 is fixed on the pipe clamp 8. The pipe clamp 8 is used for fixing, so that the pipe clamp is convenient to mount and dismount, and other fixing modes can be adopted, and the iron powder through pipe 6 can be fixed on a cutting gun.

The pipe clamp 8 can be fixed on the mixed gas pipe 4; the pipe clamp 8 can also be fixed on the cutting oxygen pipe 5. The pipe clamp 8 has two fixing positions, which means that the iron powder through pipe 6 has two positions to fix, one is to fix the iron powder through pipe 6 on the mixed gas pipe 4, and the other is to fix on the cutting oxygen pipe 5. The two fixing modes correspond to two cutting states, namely when an operator cuts the stainless steel square billet, the iron powder through pipe 6 is fixed on the cutting oxygen pipe 5 when the operator cuts the stainless steel square billet along the direction far away from the operator; when cutting in the direction close to the operator, the iron powder pipe 6 is fixed to the mixture pipe 4. To summarize, in which direction the cutting is performed, the nozzle of the dust duct 6 is always kept in front of the cutting nozzle 7 in that direction.

The utility model discloses a theory of operation is: before cutting the stainless steel square billet, filling iron powder into a powder spraying tank, connecting a gas belt on a gas inlet of the powder spraying tank, and connecting a nitrogen gas source; the powder outlet of the powder spraying tank is connected with an air belt, and the other end of the air belt is connected with one side of the iron powder through pipe 6 close to the gun handle. Compared with the condition that cutting oxygen needs to be manually opened when a traditional stainless steel hand cutting gun cuts a casting blank, the novel hand cutting gun can adjust relevant parameters before cutting operation, wherein nitrogen is adjusted to 0.2-0.3MPa, and the iron powder amount, the coal gas size and the oxygen size are manually adjusted, so that flame whitening at the wind line of the cutting gun is optimal, and the condition that the cutting oxygen needs not to be manually opened in the cutting process after adjustment is completed.

Because novel hand burning torch is when cutting stainless steel square billet, the mouth of pipe of iron powder siphunculus 6 is in the place ahead of cutting torch 7, so the iron powder that blows off can contact the cutting plane earlier, then the flame of cutting torch 7 spun just contacts the cutting plane and cuts to reach the requirement of cutting stainless steel square billet. And because the hand burning torch is light, the operating personnel can hold the hand burning torch for operation, the condition of the left and right swinging of the hand burning torch can not occur in the cutting process, the width of the cut seam which is cut out can be controlled to be 4-5mm, the smoothness of the cut section of the stainless steel square billet is ensured, the problems that the cutting speed is influenced by the slag return, the repeated cutting of the casting blank, the wider cut seam and the like caused by the left and right swinging of the hand burning torch in the cutting process are effectively avoided, and the time for cutting the casting blank is greatly shortened.

When the stainless steel square billet is not produced, the carbon steel square billet can be cut only by dismantling the stainless steel pipe, namely the iron powder through pipe 6.

Example 2

This embodiment is used for explaining the present invention specifically.

The utility model relates to a cutting stainless steel square billet is with novel hand burning torch, the material of iron powder siphunculus is the stainless steel, and the hand burning torch uses nitrogen gas to blow the iron powder in the iron powder siphunculus.

The utility model discloses a theory of operation is: the stainless steel pipe has high strength, is not easy to deform at high temperature, can ensure the spraying angle and shape of the iron powder, is commonly used, and has low cost. The nitrogen blowing device can not only blow nitrogen, but also use gas sources such as argon and the like, and the nitrogen is used in the position in order to save cost.
