Magazine type stud welding gun

Abstract

The invention discloses a magazine type stud welding gun which comprises a welding gun body, a nail containing magazine, a nail rotating barrel and a nail feeding centre. The upper end of the nail rotating barrel is fixedly connected with a main shaft body. The lower end of the nail rotating barrel is fixedly connected with a welding nail chuck. An opening is formed on the inner side face of the nail rotating barrel. The head end of the nail containing magazine penetrates through the opening to be located in an inner cavity of the nail rotating barrel. A nail collection hole communicating withthe welding nail chuck is formed in the lower end of the nail rotating barrel. A nail outlet through hole is formed in the head end of the nail containing magazine, and the tail end of the nail feeding centre can penetrate through the main shaft body and the upper end of the nail rotating barrel to abut against the top of a welding gun located in the nail outlet through hole. The nail containingmagazine is fixedly connected with a tube through a connecting assembly. According to the magazine type stud welding gun, magazine type nail feeding is achieved, multiple welding nails can be loaded easily at a time, automatic nail feeding can be achieved, the pain caused by manual loading to welding workers can be avoided, continuous welding of a certain time duration can be achieved, and the manual welding efficiency is obviously improved.

Description

technical field [0001] The invention relates to a magazine-type stud welding torch, which belongs to the technical field of stud welding equipment. Background technique [0002] Small welding studs with a diameter of less than 12mm are mainly used for fastening the glass curtain wall and fixing the refractory material on the boiler wall, which requires a lot of welding work. According to rough statistics: a 75t / h CFB (that is, the evaporation capacity is 75t / h circulating fluidized bed boiler) needs to weld about 80,000 pieces, one 220t / h CFB about 400,000 pieces, one 480t / h CFB about 500,000 pieces, and it is used for the welding of glass curtain walls of high-rise buildings The amount of welding is even greater; for such a huge welding work, manual filler welding is mainly used, because the stud welding operations on the glass curtain wall and the boiler are all high-altitude operations, all of which are extremely dense safety frames, and automatic welding equipment cannot...

[0002] Small welding studs with a diameter of less than 12mm are mainly used for fastening the glass curtain wall and fixing the refractory material on the boiler wall, which requires a lot of welding work. According to rough statistics: a 75t / h CFB (that is, the evaporation capacity is 75t / h circulating fluidized bed boiler) needs to weld about 80,000 pieces, one 220t / h CFB about 400,000 pieces, one 480t / h CFB about 500,000 pieces, and it is used for the welding of glass curtain walls of high-rise buildings The amount of welding is even greater; and such a huge welding work is mainly done by manual filler welding, because the welding operations of the studs on the glass curtain wall and the boiler are all high-altitude operations, all of which are extremely dense safety frames, and automatic welding equipment cannot be used

Although the manual filler welding method has the advantages of portability, convenient use, and low cost, the disadvantage is that manual filler is required, and the welding nails must be inserted into the welding torch chuck one by one with fingers, and the welding volume of a day is about 7000 to 10,000, one day, the welder's fingers are seriously damaged, and the operation method of only loading one welding stud at a time also seriously affects the improvement of welding efficiency, which cannot meet the needs of today's high-speed development of welding tasks.
