The invention also provides a method for adjusting the straightness of the welding opening of the band saw blade, which is carried out by adopting the device for automatically adjusting the straightness of the welding opening of the band saw blade and comprises the following steps:
the setting of the operation program is related to the width of the band saw blade 1, which is the distance from the back of the band saw blade 1 to the tip of the tooth. If the working procedure is set as follows: procedure a: the width of the band saw blade 1 is 27mm, the extending distance L1 of the driver 13 in the middle is 145.4mm, and the extending distance L2 of the drivers 13 at the two sides is 25.5 mm; procedure B: the width of the band saw blade 1 is 34mm, the extension distance L1 of the driver 13 in the middle is 138.5mm, and the extension distance L2 of the drivers 13 at both sides is 18.5 mm. Setting and storing the program in the system; that is, the width of the band saw blade 1 is inversely proportional to L1 and L2, and the larger the width, the smaller the protrusion distance.

each driver 13 acts to perform a preset program action. That is, the center gauge 14 is extended from the driver 13 located in the middle, and the end of the center gauge 14 is extended by a distance L1, so that the end portion of the center gauge 14 is structured to be extended between the two band saw blades 1 which are butted; the center gauge 14 is abutted against the back of the band saw blade 1 and is inserted and positioned with the butt seam of the two band saw blades 1;
the insulating rods 11 on the other drivers 13 extend out, so that the extending distance of the tail end of the back positioning block 10 is L2, and the back positioning block 10 is abutted against the back of the band saw blade 1 in a line contact mode;
the copper electrode 7 is mounted on the welder workbench 5 and is arranged close to the butt joint. Copper electrode 7 is the outsourcing spare, and single copper electrode 7 has two parts about, and gapped between two parts about and, copper electrode is fixed down, goes up the copper electrode and installs on the hydro-cylinder. In operation, the band saw blade is placed in the copper electrode 7 (avoiding the tooth tip position). After the band saw blade is put in, the copper electrode on the band saw blade is pressed down, the saw blade is pressed firmly and immovably, then welding is carried out, the copper electrode 7 is always in a pressing state in the welding process, and good conductive performance is provided, so that welding is realized;
step 2.2, withdrawing the center gauge 14 from the butt joint for a certain distance;
and 3, starting welding until the welding is finished. The finished band saw blade 1 is formed in a slightly curved upward arc shape at the back.
The three drivers 13 can be simultaneously fine-tuned, or each driver can be independently fine-tuned, and when the operators operate, the operators only need to click the buttons for increasing or decreasing the fine-tuning travel of the interface.
In addition, it should be noted that the center gauge needs to be withdrawn for a certain distance to prevent damage when the band saw blade is welded, so that the length of the center gauge is shorter than that of the insulating rods on the left and right side drivers. When the program is set, the protruding length of the center gauge on the middle shaft needs to be long, and therefore after the center gauge and the insulating rod protrude according to the preset program, the positions of the center gauge, the insulating rod and the insulating rod are basically flush.
