SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a welder scarfing cinder sword can effectively clear away remaining welding slag that splashes after welder uses fast. The technical problem of the utility model is realized through following technical scheme: the utility model provides a welder scarfing cinder sword, the cutter body of scarfing cinder sword is the cylinder, the cutter body side surface sets up open-topped longitudinal groove, longitudinal groove is on a parallel with the drum axis, longitudinal groove one side is preceding blade, and the offside is the back cell wall, back cell wall top is the cell wall top, the top of preceding blade is for playing the sword end, it is higher than the cell wall top to play the sword end in vertical space, the edge is seted up to cutter body top surface, it is the cylinder helix to go up the shape orbit of blade.

Further, the bottom end of the longitudinal groove is an arc-shaped surface.

Further, the width of the longitudinal groove is 50-70 degrees in the span of the cylindrical surface of the cutter body.

Further, the angle of the front cutting edge is 50-70 degrees.

Further, the bottom of the cutter body is provided with threads, and the threads are coaxial with the cutter body.

Further, the height of the thread is the same as the distance from the lowest part of the longitudinal groove to the top surface of the thread.

To sum up, the utility model discloses following beneficial effect has:

the utility model discloses set up open-top's vertical groove with the scarfing cinder sword at the cutter body side surface, blade before vertical groove one side sets up, blade top surface edge is seted up and is gone up the blade, wherein goes up blade shape orbit and be the cylinder helix, enables the cutter body and changes inside the screw in welder, goes up blade and preceding blade and carries out residue scraping work to the welder inner wall simultaneously, clears up high-efficient thoroughly more.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model discloses a welder scarfing cinder sword. Referring to fig. 1-5, a slag removing tool for a welding gun, a tool body 1 of the slag removing tool is cylindrical, a cylindrical outer wall of the slag removing tool can be well attached to an inner wall of the welding gun, a longitudinal groove 2 with an open top is arranged on a side surface of the tool body 1, the longitudinal groove 2 is parallel to a central axis of the cylinder, a front cutting edge 3 is arranged on one side of the longitudinal groove 2, a rear groove wall 4 is arranged on the opposite side of the longitudinal groove 2, and the longitudinal groove 2 mainly has two functions: firstly, discharge welding slag, secondly the preceding blade 3 that the side set up can assist scrapes the residue.

As shown in fig. 3, the width of the longitudinal groove 2 spans 50 to 70 degrees on the cylindrical surface of the cutter body 1, which not only can meet the requirement of rapid discharge of scraped welding slag, but also can meet the requirement of hardness of the cutter body 1, and the service life can be ensured. The bottom of longitudinal groove 2 is the arcwall face, and the welding slag is difficult for storing up in the arc bottom surface, and makes cutter surface design more pleasing to the eye.

The angle of the front cutting edge 3 is also 50 degrees to 70 degrees and is generally set to be 60 degrees, the top end of the rear groove wall 4 is the groove wall top end 6, the top end of the front cutting edge 3 is a cutter lifting end 7, the cutter lifting end 7 is higher than the groove wall top end 6 in the vertical space, the edge of the top surface of the cutter body 1 is provided with an upper cutting edge 5, the shape track of the upper cutting edge 5 is a cylindrical spiral line, and the peak of the cutter lifting end 7 can scrape residues in a labor-saving manner when contacting welding slag on the inner wall of a welding gun and can be deeply driven along with the rotation of the cutter lifting end 7, so that a cutter can be conveniently driven to enter the welding gun and completely remove the welding slag in the welding gun.

As shown in fig. 4, the bottom of the cutter body 1 is provided with a thread 8, the thread 8 is coaxial with the cutter body 1, the cutter body 1 can be fixed on an external controller through the thread 8 by means of an external electric tool, the cutter body 1 is controlled to work, manual slag removal is not needed, and the efficiency is higher. The height of the thread 8 is the same as the distance from the lowest position of the longitudinal groove 2 to the top surface of the thread 8, so that enough slag discharging space is reserved in the cutter body 1, and residues are not easy to accumulate and block the inner cavity of the cutter body 1.

The utility model discloses a theory of operation does: when the welding gun slag removing cutter is used, manual screwing or installation on an external electric control clamp can be selected, the welding gun is screwed in through mechanical control, the cutter starting end 7 firstly contacts welding slag in the screwing-in process, the welding slag is scraped along a cylindrical spiral line of the upper cutting edge 5, auxiliary residue scraping of the side wall is carried out on the front cutting edge 3, and the scraped welding slag falls into the inner cavity of the cutter body 1 and is discharged from the longitudinal groove 2.
