Summary of the invention
The purpose of this utility model is to provide the automatic submerged arc welding machine of a kind of simple in structure, even weld, welding circular weld that production efficiency is high.
The purpose of this utility model is to realize like this, a kind of submerged arc welding machine, comprise lathe bed, be positioned at the headstock of lathe bed one end, be positioned at the submerged-arc welding device of the lathe bed other end, described headstock is outer to be equipped with chuck towards the position of submerged-arc welding device, be provided with in the headstock by gearbox and drive the chuck motor rotating, described submerged-arc welding device comprises upright arm, in the upright arm lowering or hoisting gear is installed, the longitudinal rail and the cross slide way of lowering or hoisting gear are affixed, there are a support arm and cross slide way to be slidingly connected, the free end of support arm is provided with soldering tip and welding flux box, and wire feeder and soldering wire box also are installed on the support arm.
As to improvement of the present utility model, the front certain distance of described soldering tip pad also is provided with one and is installed in the free-ended preheating head of support arm.As to further improvement of the utility model, the discharging opening of described welding flux box also is provided with the adjusting device that can regulate discharging.
As further improving of the present utility model, described motor is an electromagnetic varispeed motor.
The utility model is owing to adopted said structure, a kind of submerged arc welding machine comprises lathe bed, be positioned at the headstock of lathe bed one end, be positioned at the submerged-arc welding device of the lathe bed other end, described headstock is outer to be equipped with chuck towards the position of submerged-arc welding device, be provided with in the headstock by gearbox and drive the chuck motor rotating, described submerged-arc welding device comprises upright arm, in the upright arm lowering or hoisting gear is installed, the longitudinal rail and the cross slide way of lowering or hoisting gear are affixed, there are a support arm and cross slide way to be slidingly connected, the free end of support arm is provided with soldering tip and welding flux box, wire feeder and soldering wire box also are installed on the support arm, two workpiece of the circular weld of needs welding are at first aligned and the fixing solder joint of spot welding several, then workpiece is installed on the chuck, adjust the lowering or hoisting gear of installation in the upright arm and the support arm on the cross slide way, with soldering tip and welding flux box discharging opening near weld seam, starter motor, driven by motor is installed on the workpiece rotation on the chuck, open soldering tip and welding flux box discharging opening, weld job can begin, this shows, this machine is simple in structure, easy to operate, unmanned in the operation process is the factor intervention, thereby even weld, welding quality is good, the production efficiency height.As to improvement of the present utility model, the front certain distance of described soldering tip pad also is provided with one and is installed in the free-ended preheating head of support arm, like this, has saved artificial preheating, can realize the automation of whole welding process.
As to further improvement of the utility model, the discharging opening of described welding flux box also is provided with the adjusting device that can regulate discharging, like this, can regulate the load of solder flux, to reach good welding effect and to reduce welding cost according to the specification requirement of the size of weld seam and welding.As further improving of the present utility model, described motor is an electromagnetic varispeed motor, and like this to the circular weld of different-diameter, the linear velocity of easier its pad of adjusting is consistent, thereby is easy to control welding quality.
The specific embodiment
As shown in drawings, a kind of submerged arc welding machine comprises lathe bed 1, be positioned at the headstock 2 of lathe bed 1 one ends, be positioned at the submerged-arc welding device of lathe bed 1 other end, towards the position of submerged-arc welding device chuck 3 is installed outside the described headstock 2, be provided with in the headstock 2 by gearbox 4 and drive chuck 3 motor rotating 5, described submerged-arc welding device comprises upright arm 6, in the upright arm 6 lowering or hoisting gear 7 is installed, the longitudinal rail 8 of lowering or hoisting gear 7 is affixed with cross slide way 9, there is a support arm 10 to be slidingly connected with cross slide way 9, the free end of support arm 10 is provided with soldering tip 11 and welding flux box 12, and wire feeder and soldering wire box 13 also are installed on the support arm 10.The front certain distance of described soldering tip 11 pads also is provided with one and is installed in support arm 10 free-ended preheating heads, and this preheating head can adopt combustion gas such as acetylene gas, coal gas or liquefied gas preheating.The discharging opening of described welding flux box 12 also is provided with the adjusting device that can regulate discharging, and this adjusting device can adopt device and other known structures of a kind of similar gate.Described motor 5 electromagnetic varispeed motors.
Two workpiece of the circular weld of needs welding are at first aligned and the fixing solder joint of spot welding several, then workpiece is installed on the chuck, adjust the lowering or hoisting gear of installation in the upright arm and the support arm on the cross slide way, with soldering tip and welding flux box discharging opening near weld seam, starter motor, driven by motor is installed on the workpiece rotation on the chuck, open preheating head, soldering tip and welding flux box discharging opening, weld job can begin, this shows, this machine is simple in structure, easy to operate, unmanned in the operation process be the factor intervention, thereby even weld, welding quality is good, production efficiency is high.
