Problems solved by technology
The opportunity loss caused by the downtime of the continuous annealing unit is very huge, because it will take several hours for the furnace to cool down and heat up after the failure of the welding machine, which seriously affects the production capacity of the unit
In the past, to prevent scrap strip steel from absorbing the blade, two copper tubes were used to purge the inner side of the blade, and its mechanical structure is as attached figure 1 , but the purging effect of this structure and control method is very poor, resulting in the situation that the blade absorbs the strip steel from time to time

Embodiment 1
[0017] A control device and method for eliminating the adhesion of steel by the magnetic scissors of an ultra-thin material lap welding machine, changing the design idea of purging the copper tube in two ways in the traditional design, and adopting a four-way purging form. The originally installed copper tube is to be removed and replaced with a newly designed copper tube, two of which are respectively installed inside the blade, in the form of openings on the side of the copper tube, and the air blowing holes 11 are evenly arranged in the axial direction of the copper tube to align with the welding machine blade Perform a purge. (if attached image 3 , 4 shown). The other two roads are installed on the outside of the scissors of the welding machine, which are the outlet scissors 3 and the inlet scissors 4. Install the air pipe fixing bracket on the clamping guide plate of the welding machine inlet 5 and outlet 1, and evenly install a number of copper pipes on the bracket...

The invention relates to a control device and method for eliminating adhering strip steel of extremely thin material overlap joint welding machine magnetic scissors. Newly-designed copper pipes are adopted, wherein two paths are respectively installed on the inner side of a blade; in the mode of trepanning on the side surface of the copper pipe, blow holes are evenly and axially arranged on the copper pipe; the blade of a welding machine is blown accurately; the other two paths are installed on the outer side of the mouth of the welding machine scissors; clamping guide plates on the inlet and outlet of the welding machine are provided with air pipe fixing supports; each support is evenly provided with a plurality of copper pipes; the blowing direction of the copper pipes is aligned with the outer side of the cutter point of the welding machine blade; and a groove on the lower side of the welding machine blade is provided with waste tank chain magnetic plates which are evenly arranged at intervals. The device and method provided by the invention have the advantages that the structure and control mode of the blowing device are changed, and a magnetic strip is additionally arranged in the waste groove below the scissors to vertically and downwards adsorb the strip steel, thereby preventing the strip steel from being adsorbed on the blade of the scissors.
Description
【Technical field】 [0001] The invention relates to the technical field of lap welding machines, in particular to a control device for eliminating the magnetic scissors of lap welding machines for ultra-thin material from sticking to strip steel. 【Background technique】 [0002] At present, Chinese iron and steel enterprises, such as Baosteel 1220, are ultra-thin material production units, with the thinnest specification of 0.15mm, using lap welding machines to connect two coils of strip steel for continuous production. In the normal production process, welding machine sticking steel failure often occurs for extremely thin materials, that is, the scrap strip steel that has been cut sticks to the shear blade of the welding machine, resulting in the situation that the scrap material and the useful strip steel are welded together. Due to the high current resistance welding of the lap welding machine, the effect of electromagnetic induction causes the blade and guide plate of the w...
