Description
The present invention relates to a kind of band transformer hanging spot-welder, constitute by welding transformer, pneumatic actuator system, water cooling system, soldering turret, slewing equipment and control cabinet, be specially adapted to the mild steel workpiece that general fixed spot welder can not weld or inconvenience is welded.
In technique known, " the DN that Chengdu Electric Welding Machine Factory produces
3The series hanging spot-welder "; be to use more a kind of typical products at home; mainly by welding transformer, gas--hydraulic pressure or pneumatic actuator system, cable, soldering turret, control cabinet, balancer are formed, and its weak point is that energy consumption height, volume are big and heavy, operation is dumb, it is inconvenient to use.In addition, also has a kind of known welding rifle, that is exactly the series of products that France " ARO " company produces, its main composition comprises soldering turret, water cooling system, welding transformer, cylinder, gyro hanger bracket, its weak point is that the Water cooling cable internal diameter of transformer secondary output is little, the underfed of cooling water, cause the welding transformer temperature rise fast, employed cooling water must be handled through softening, otherwise incrustation scale can stop up the endoporus of transformer secondary output Water cooling cable, be directed at the welding machine cisco unity malfunction, even cause transformer to burn.Its last soldering turret is vertically mounted on the upper support arm, and its upper end easily contacts welded piece and forms the electric current shunting, and this not only influences welding quality, and the position of its energy soldering group component is very restricted.The electrode stem of soldering turret and transformer secondary output adopt copper sheet to flexibly connect, its junction contact-making surface is little and resistance is big, when the solder joint of welded piece and the edge of work increase apart from lengthening welding edge apart from the time, the electric current damping characteristic is obvious, Weldability descends, even can not normally weld.The gyro hanger bracket is fixed on a side of spot welding machine, and during suspension, spot welding machine is inclined, and the work people operates and must set upright.Not only make troubles to operation, also expend workman's muscle power, horizontal plane rotation (around the Z axle) depends on hoist cable to realize flexible the rotation entirely, in the work hoist cable is rived off promptly dangerous, also dumb.
The object of the present invention is to provide a kind of efficient height, energy savings, can realize interiorly to manage oil-cooled transformer, walk the band transformer hanging spot-welder of heat by water cooling system water flowing salband what the multi-layer thin steel plate welded.
Purpose of the present invention can reach by following measure: this spot welding machine is by welding transformer, pneumatic actuator, soldering turret, cooling water system, slewing equipment and control cabinet constitute, its special character is that the secondary winding of welding transformer is managed 57 closed assemblies and formed by being no less than the tri-layer level, and the material of secondary copper pipe is a red copper, and section configuration is positive square tube or rectangular pipe.
