Or after the connecting pipe and the cylinder body are assembled and welded, the inner port end face and the welding seam of the cylinder body connecting pipe are subjected to surfacing welding together to form the composite layer.
Disclosure of Invention
In order to improve the composite bed build-up welding work efficiency that the thick wall of shape of a saddle terminal surface was taken over, improve welding quality, improve workman operational environment, the utility model provides a device for the build-up welding of shape of a saddle terminal surface was taken over.
The utility model discloses a main technical scheme: the device for surfacing the end face of the saddle-shaped connecting pipe is characterized by comprising a semi-automatic gas shield welding gun and a welding positioner; the welding gun is fixed on the adjustable welding support, and the horizontal and vertical positions of the welding gun are adjusted and fixed through an adjusting knob of the adjustable welding support; the adjustable welding support is arranged on the welding positioner platform, the saddle-shaped connecting pipe to be subjected to surfacing welding is horizontally arranged on a rotary table of the welding positioner, and the end face to be subjected to surfacing welding is upward.
Preferably, the adjusting knob comprises an upper shaft, a lower shaft and a horizontal shaft adjusting knob.
Preferably, the adjustable welding bracket is fixed on the platform of the welding positioner through a welding bracket base.
Preferably, the saddle-shaped connecting pipe to be subjected to surfacing welding is horizontally arranged on a rotary table of the welding positioner through a plurality of cushion blocks, and the positions of the cushion blocks are provided with flange sealing surfaces and are uniformly arranged.
The utility model is used for the device of saddle-shaped takeover terminal surface build-up welding because adopt the welding to shift the rotatory work piece of ware, the welding rifle head is fixed, makes electric arc very stable, and weld forming obtains guaranteeing. By adopting semi-automatic welding, the working efficiency is about three times of that of manual surfacing welding. An operator can keep a longer distance with a workpiece after adjusting the position of the gun head, only the knob needs to be operated, and the working environment is improved compared with manual surfacing. In the welding process, an operator only needs to adjust the height up and down along the saddle-shaped overlaying surface, and the requirement on the skill level of a welder is low by ensuring one half of a pressing channel in the channel changing process.
The utility model discloses, work efficiency, welding quality improve by a wide margin, and operating personnel need not be very close from the work piece that heats, has improved operational environment greatly.

Fig. 1 is a schematic structural diagram of a saddle-shaped connecting pipe end surface overlaying device in an embodiment of the present invention.
In the figure, 1-welding positioner, 2-turntable, 3-cushion block, 4-connecting pipe, 5-end surface to be welded, 6-welding gun, 7-bracket, 8-upper and lower shaft adjusting knob, 9-horizontal shaft adjusting knob and 10-bracket seat.
Detailed Description
The present invention will be described in detail with reference to the following embodiments and drawings.
Examples
The device for surfacing welding of the end face of the saddle-shaped connecting pipe mainly comprises a semi-automatic gas shield welding gun 6 and a welding positioner 1, wherein the welding gun 6 is fixed on an adjustable welding support 7, and the horizontal and vertical positions of the welding gun 6 are adjusted and fixed through an adjusting knob of the adjustable welding support 7; the adjustable welding support 7 is arranged on a platform of the welding positioner 1, the saddle-shaped connecting pipe 4 to be subjected to surfacing welding is horizontally arranged on a rotary table 2 of the welding positioner, and the end face 5 to be subjected to surfacing welding faces upwards.
In the embodiment, the adjusting knob of the adjustable welding bracket comprises an upper shaft adjusting knob 8, a lower shaft adjusting knob 8 and a horizontal shaft adjusting knob 9; the adjustable welding support 7 is fixed on the platform of the welding positioner 1 through a welding support seat 10.
The device of embodiment, when using, wait to build up welding saddle-shaped takeover 4 through 3 levels of a plurality of cushions arrange in the revolving stage 2 of welding dislocation ware in, cushion 3 positions let open the flange seal face to evenly put, prevent that sealed face from striking sparks the damage, perhaps collide with the damage, conveniently lift by crane simultaneously.
The device of the embodiment adopts a semi-automatic gas shielded welding mode, the connecting pipe with the saddle-shaped end surface is horizontally placed on the welding positioner rotary table and rotates at a constant speed in the horizontal direction, the adjustable welding support is fixed on the side surface of the connecting pipe, and the head of a gas shielded welding gun is fixed on the adjustable support. The welding positioner rotary table is horizontally rotated, the gun head is fixed in the horizontal direction to form a circular welding bead, the height fluctuation of the saddle surfacing surface is followed through the adjustment of the upper and lower shaft adjusting knobs, and the lane changing operation is realized through the adjustment of the horizontal shaft adjusting knobs.
Before welding, firstly, the position changer is adjusted to a horizontal position, the connecting pipe is aligned, then the position of a gas shield welding gun is adjusted, the angle of the gun head is vertical and downward, and the vertical adjustment allowance of the support is reserved according to the vertical difference value of the saddle-shaped end surface of the connecting pipe. And reserving a support horizontal adjustment allowance according to the thickness of the pipe wall. And after the alignment is finished, preheating and heating the thick-wall connecting pipe.
In the welding process, the upper shaft and the lower shaft only need to be adjusted in each circle, and the extending length of the carbon dioxide gas shielded welding wire is guaranteed to be approximately consistent. The welding wire is stretched out to a certain extent, and the voltage parameter is reduced properly, so that the up-down adjustment times in the welding process can be reduced, and the workload of operators is reduced. The lane changing positions are arranged at four points of the highest point or the lowest point, the height change near the four points is relatively smooth, and the lane changing device is suitable for simultaneous operation of an upper shaft, a lower shaft, a left shaft and a right shaft or alternate operation with short interval time.
According to the surfacing device, the welding positioner is adopted to rotate the workpiece, and the welding gun head is fixed, so that electric arc is stable, and welding forming is guaranteed. By adopting semi-automatic welding, the working efficiency is about three times of that of manual surfacing welding, and the production efficiency is greatly improved. An operator can keep a longer distance with a workpiece after adjusting the position of the gun head, only the knob needs to be operated, and the working environment is improved compared with manual surfacing. In the welding process, an operator only needs to adjust the height up and down along the saddle-shaped overlaying surface, and the requirement on the skill level of a welder is low by ensuring one half of a pressing channel in the channel changing process.
