Description

A cleaning tool for welding slag at the head of a welding torch

technical field

The invention relates to a tool for cleaning up the welding slag accumulated in the torch head of a welding torch.

Background technique

During the welding process of the welding torch, the molten metal welding slag will deposit and solidify at the tip of the welding torch, especially in the gap formed by the inner wall of the gas guiding sleeve and the outer wall of the contact tip, it is easy to accumulate welding slag. The process is very unfavorable, and in order to achieve high-quality welding results, the torch tip must be cleaned frequently. However, due to the special structure of the torch head, it brings many difficulties to the cleaning work.

The original cleaning method is to use needle-nose pliers or other sharp tools to penetrate into the gun head, that is, the gap formed by the inner wall of the gas guide sleeve and the outer wall of the contact tip. The slag is cleaned up. This cleaning method is difficult to operate and cannot be cleaned cleanly. Larger welding slag or welding slag that sticks more firmly can only be cleaned thoroughly by removing the gas guide sleeve of the welding torch.

Contents of the invention

The technical problem to be solved by the present invention is to provide a tool which is easy to operate and can thoroughly remove welding slag from the tip of the welding torch.

In order to achieve the above object, the present invention provides a cleaning tool for welding slag on the head of a welding torch, which includes a long rod (1). The key is: one end of the long rod (1) is a conical head (2), and the conical The head (2) has a cylindrical hole (3) coaxial with the conical head (2), and the conical head (2) also has a gap (4) that runs through the left and right sides of the conical head (2) , the axis of the conical head (2) is located on the longitudinal center plane of the notch (4), the height of the notch (4) is smaller than the diameter of the cylindrical hole (3), the cylindrical hole (3) and The depth of the notch (4) is greater than the length of the conical head (2); the conical head (2) also has a conical hole (5) coaxial with the conical head (2), the The large end of the conical hole (5) faces outward, the diameter of the large end of the conical hole (5) is smaller than the diameter of the small end of the conical head (2), and the depth of the conical hole (5) is smaller than that of the conical head (2) length.

When the tool cleans the welding slag on the tip of the welding gun, the conical head part extends into the gap formed by the inner wall of the gas guiding sleeve of the welding torch and the outer wall of the contact tip, and the conical head is the working part of the tool. The outer surface of the conical head is the guiding surface of the air guide sleeve, and the conical hole is the guiding surface of the contact tip. The notch on the conical head runs through the left and right sides of the conical head. The axis of the conical head is located on the longitudinal center plane of the notch, forming a symmetrical notch up and down; Four junctions. Among the four boundary lines, the two boundary lines between the outer surface of the conical head and the notch become the cleaning edges of the inner wall of the air guide sleeve, and the two boundary lines between the cylindrical hole and the notch become the cleaning edges of the outer wall of the contact tip. The depth of the cylindrical hole is greater than the length of the conical head, which reserves enough space for the welding wire of the torch head, and the depth of the notch is greater than the length of the conical head, so that the cleaned welding slag can be discharged out of the cleaning tool in time.

The long rod (1) is a cylinder whose diameter is equal to the diameter of the large end of the conical head (2) and coaxial. The cylindrical rod is easy to hold, and its diameter is equal to that of the conical head, so that the junction with the conical head is more beautiful and the processing is more convenient.

The other end of the long rod (1) is connected with the handle (6), so that the tool can be screwed in and out of the welding torch more labor-saving.

The material of the conical head (2) is 40Cr, and the length of the conical head (2) is 10mm-20mm, so as to ensure that the conical head has sufficient strength and is not easy to wear, and at the same time has enough length to penetrate into the welding torch for effective cleaning.

The beneficial effects of the invention are:

1) The cleaning tool has its own guiding function and slag discharge function, which is easy to operate and use, and it is faster to clean the welding slag;

2) The inner wall of the gas guide sleeve of the welding torch and the outer wall of the contact tip are cleaned at the same time through the naturally formed cutting edge, which ensures that the welding slag of the welding torch tip is removed more thoroughly;

3) With the handle, the tool can be screwed in and out of the welding torch head, saving time and effort, and has a beautiful appearance. .

Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

As shown in Fig. 1 and Fig. 3, a cleaning tool for welding slag at the tip of a welding torch is composed of a cylindrical long rod 1 and a conical head 2. The conical head 2 is arranged on one end of the long rod 1, and the diameters of the long rod 1 and the large end of the conical head 2 are equal, and both are coaxial.

As shown in Figure 1 and Figure 2, there is a cylindrical hole 3 coaxial with the conical head 2 on the conical head 2, the depth of the cylindrical hole 3 is greater than the length of the conical head 2, and the cylindrical hole 3 starts from the small end of the conical head 2 Extend into the long pole 1 all the time.

As shown in Figures 1 to 3, the conical head 2 has a gap 4 that runs through the left and right sides of the conical head 2. The axis of the conical head 2 is located on the longitudinal center plane of the notch 4, and the longitudinal center plane of the notch 4 is a horizontal plane. The central plane passes through the axis of the conical head 2, so that the notch 4 is symmetrical up and down relative to the longitudinal central plane. The height of the gap 4 is less than the diameter of the cylindrical hole 3; The notch 4 and the cylindrical hole 3 opened on the conical head 2 naturally form four boundary lines between the conical head 2 and the notch 4 . Among the four boundary lines, the two boundary lines between the outer surface of the conical head 2 and the notch 4 become the cleaning edge a of the inner wall of the air guide sleeve, and the two boundary lines between the cylindrical hole 3 and the notch 4 become the outer wall of the contact tip The cleaning edge b. The outer end of conical head 2 also has the conical hole 5 that is coaxial with conical head 2, and the big end of conical hole 5 is outwards, and the big end diameter of conical hole 5 is less than the small end diameter of conical head 2, and the conical hole 5 The depth is less than the length of the conical head 2,. The outer surface of the conical head 2 is the guiding surface of the gas guiding sleeve of the welding torch, and the conical hole 5 is the guiding surface of the conductive tip of the welding torch.

As shown in FIG. 4 , the other end of the long rod 1 is connected to the handle 6 .

The material of the conical head 2 is 40Cr, and it can also be made of other materials with higher hardness. The length of the conical head 2 is preferably 10 mm to 20 mm. The cross-sectional shape of the long rod 1 can also be a quadrangle, a polygon, etc., which all fall within the scope of protection of the present application model.

As shown in FIG. 4 , the inner wall 11 of the gas guide sleeve and the outer wall 12 of the contact tip form a gap, and welding slag is most likely to be deposited and solidified in the gap. The front end of welding torch has welding wire 13. When the tool cleans the welding slag of the torch head, the conical head 2 part extends into the gap of the torch head, the outer surface of the conical head 2 is the guiding surface of the gas guide sleeve, and the conical hole 5 is the guiding surface of the conductive tip. The depth of the cylindrical hole 3 is greater than the length of the conical head 2, which reserves enough space for the welding wire 13 of the torch head, and the depth of the notch 4 is greater than the length of the conical head 2, so that the cleaned welding slag is discharged in time outside the cleaning tool.
