Description

The dual-purpose machine of butt welding repaired mouth

The utility model relates to field of welding devices, specifically is meant a kind of equipment that possesses butt welding and spot welding dual-use function, in particular for the equipment of band saw bar repaired mouth and butt joint.

At present, raising along with living standards of the people, factors such as beautification of rooms have been brought the development of wood-processing industry, and timber is when being processed into well-regulated plank or batten, must finish with band sawing machine, and band sawing machine the most flimsy be bands for band, every bands for band cost is about about 80 yuan, regular replacing makes the owner of band sawing machine be difficult to bear the expense of its expenditure, for this reason, people are after the bands for band on the band sawing machine is broken or fractureed, adopted the method for welding, bands for band can be reused, in welding method, silver soldering, gas welding is the method that adopts the earliest, they generally all need to control with hand, the one, consume scolder in a large number, increase the cost expenditure, the 2nd, the welding position is uneven, poor welding quality, disconnected again rate height, the 3rd, during sawn timber, the saw blade lateral displacement is big, timber loss late height, as it is even more serious to process its economic loss of precious wood, so, what extensively employing was gone up by society now is duct butt-welding method, and has produced butt welding machine, and the present utility model people is exactly one of member who produces by this butt welding machine, it must not add any solder flux and auxiliary material when welding, it is strong that bands for band after the welding has stretching resistance, the work efficiency height, and cost is low, characteristics such as simple to operate, this butt welding machine belongs to melting butt welding in the Contact welding, but its principle is to be fixed by anchor clamps on the pole plate of the bands for band voltage controller power source that the transformer secondary output coil is drawn in butt welding machine, guarantees the straight contact in saw blade two ends, welding current is transmitted to saw blade end-fitting place by secondary coil, because contact area is little, current density is very big, the very fast fusing of the metal of contact point, under magnetic field and forceful action, the spark of end metal is seted out, and temperature surpasses melting point metal at short notice, heat is to internal delivery, when heat transmits when reaching enough degree of depth to the deep, accelerate the saw blade translational speed immediately, after a while deenergization in a flash, like this to the saw blade of postwelding, its welding position still rigidity is strong, and not folding is also disconnected easily, must carry out annealing in process, annealing is also carried out on butt welding machine, but but the voltage controller power source voltage of selecting for use is lower slightly, and the processing time will lack, crux is to grasp the temperature of contact site at 500 ℃ to 600 ℃, and suitably regulate, therefore, butt welding and annealing are two important operations in the duct butt-welding method, otherwise be difficult to the effect that reaches desirable, however, bands for band often has breach earlier when using, after fracture again, when breach occurring, the method that adopts has oxygen welding and silver soldering at present, and pad warpage radius is big, timber loss late height, as butt joint again after often blocking, saw blade is shorter and shorter, and reduce service life, and people press for a kind of butt joint of searching and the annealing function has both, can butt welding can handle breach again, to prolong bands for band service life, improve a kind of concise and to the point equipment of timber processing and utilization rate, such equipment is found on market so far as yet.

To be that design is a kind of improve existing butt welding machine the purpose of this utility model slightly, increase have the device of spot welding repaired mouth function after, make it possess the dual-purpose machine of butt welding repaired mouth of butt welding and spot welding dual-use function.

The technical solution of the utility model is the dual-purpose machine of a kind of butt welding repaired mouth of design, comprise that transformer is formed in butt welding machine body and the butt welding machine, the axle sleeve one end projection of its movable soldering tip parts, be built-in with back-moving spring and hollow plunger, back-moving spring and hollow plunger Elastic Contact, the end and the nut that play the stopper rod of connection effect join, and the other end is connected in series with soldering tip with hollow plunger, axle sleeve, hollow column sleeve, electrode in order; The stopper rod that the plays the connection effect one end attaching nut of its fixedly soldering tip parts, the other end is connected in series with soldering tip with the axle sleeve that has through hole, hollow column sleeve, electrode in order; But the electrode of movable soldering tip parts and fixing soldering tip parts is connected with the two poles of the earth of the voltage controller power source that the output of the secondary coil of the interior transformer of butt welding machine is drawn.Through after above-mentioned the setting, movable soldering tip parts and fixedly the soldering tip parts all by pedestal, by coaxial relatively, leave distance between two soldering tips and arrange, and all be arranged on the butt welding machine body with the parts of controlling movable soldering tip.

The weldering of the utility model set pair, the repaired mouth function is in one, greatly facilitate the user, for having saved, the user drops into the expense of purchasing spot-welding equipment again, the power supply of this utility model is taken from the secondary coil of the transformer in the butt welding machine, one of makes device dual-purpose, has improved utilization rate of equipment and installations, because its welding quality is good, technology advanced person, each saw blade breach costs with 0.03 yuan, and with oxygen welding about 0.1 yuan, and it is of poor quality, the warpage radius is big, therefore converted timber loss late height, the utlity model has development prospect, and safety coefficient height, the anxiety of no fire and blast, its transformer-secondary voltage is lower than the human safety voltage, does not have the danger of electric shock.

Provide detailed embodiment of the present utility model below in conjunction with accompanying drawing.
