Description

Technical Field

[0001] The invention relates to the technical field of stud welding, in particular to semi-automatic stud welding equipment. Background Art

[0002] Stud welding is a method of contacting one end of the stud with the surface of the plate (or pipe) to be processed, energizing the arc, and applying a certain pressure to the stud after the contact surface melts to complete the welding. The cylindrical head welding nails used for arc stud welding are suitable for high-rise steel structure buildings, industrial plant buildings, roads, railways, bridges, towers, automobiles, energy, transportation facilities, airports, stations, power stations, pipeline supports, lifting machinery and other steel structures. The basic principle of arc stud welding is to ignite an arc between the stud to be welded and the workpiece. When the stud and the workpiece are heated to a suitable temperature, under the action of external force, the stud is sent into the welding pool on the workpiece to form a welded joint. Compared with other welding methods, arc stud welding equipment is more beautiful, efficient and strong.

[0003] Although the stud welding equipment in the prior art can efficiently and firmly weld the studs, it is inevitable that there are still some shortcomings in the actual use process.

[0047] The specific steps for using and operating the device are as follows:

[0048] Before use: insert the plate 11 to be processed into the placement rack 10 in advance, and fit the rear side of the plate 11 to be processed with the front side of the push plate 134, and simultaneously put a plurality of studs 128 to be clamped and welded into the plurality of placement slots 127 in the loading tray 126 in an orderly manner;

[0049] S1, automatic welding and rotating welding stations: the electric telescopic rod 913 drives the equilateral tripod 915 and the tooth plate 914 to descend and ascend to reset, so that the installation pad 3 drives the front stud welding gun 6 to automatically descend to weld the stud 128 on the top of the plate 11 to be processed;

[0050] The specific steps are as follows: manually remove the powered clamp 7 connected to the power supply 5 on the front side from the hanging state in advance, and clamp the powered clamp 7 on the surface of the panel 11 to be processed, with the specific clamping position being at the powered clamping groove 24; then start the electric telescopic rod 913, the extended end of the electric telescopic rod 913 extends out and drives the equilateral tripod 915 and the tooth plate 914 to descend; the equilateral tripod 915 descends and contacts the top of the mounting pad 3, and pushes the mounting pad 3 to descend; the mounting pad 3 descends and drives the extension plate 4 to move; the extension plate 4 drives the stud welding gun 6 to descend; the stud welding gun 6 carries the stud clamping arc plate 8 to descend; the stud clamping arc plate 8 carries the stud 128 to descend, until the bottom of the stud 128 in the front stud clamping arc plate 8 abuts against the top of the panel 11 to be processed, and the extension plate 4 is lowered The fall drives the striker 26 to fall at the same time. The striker 26 falls and contacts the top of the push plate 134 in advance. The thickness of the push plate 134 is consistent with that of the plate 11 to be processed. As the stud 128 in the front stud clamping arc plate 8 is about to abut against and fit with the plate 11 to be processed, the striker 26 will press the control button 27 accordingly. The power supply machine 5 under the force of the control button 27 energizes the power-on clamp 7 and the stud welding gun 6. The power-on clamp 7 inputs current to the plate 11 to be processed, and the power supply machine 5, the power-on clamp 7, the plate 11 to be processed, and the stud welding gun 6 form a passage, so that an arc is generated between the stud 128 in the stud clamping arc plate 8 and the contact surface of the plate 11 to be processed, and a large current is generated, so that the bottom end protrusion of the stud 128 is hot-melted with the contact surface of the plate 11 to be processed and welding is formed under the condition of applying downward pressure;

[0051] When the corresponding front side stud clamping arc plate 8 is subsequently pulled up and reset with the installation pad 3, the stud 128 welded by the stud clamping arc plate 8 will be welded to the plate 11 to be processed, and the stud 128 in the front side stud clamping arc plate 8 will be intercepted by the top block of the placement frame 10, so that the stud 128 in the front side stud clamping arc plate 8 is completely removed. During the corresponding rising and removing process, the energized clamp 7 with current flowing through it needs to be manually removed from the plate 11 to be processed;

[0052] When the extended end of the electric telescopic rod 913 drives the equilateral tripod 915 to descend, the extended end of the electric telescopic rod 913 simultaneously drives the toothed plate 914 to descend, and the toothed plate 914 will mesh with the gear 912 when descending, prompting the gear 912 to drive the second rotating rod 907 and the two-way rotating disk 908 to rotate, and the two-way rotating disk 908 drives the arc-shaped stop block 910 to rotate. Since the first rotating rod 902 connecting the one-way rotating disk 904 and the arc-shaped inclined block 906 is controlled by the non-return mechanism 905, and the rotation of the arc-shaped stop block 910 is carried out along the inclined surface of the arc-shaped inclined block 906, the arc-shaped stop block 910 will be continuously squeezed and retracted into the inside of the two-way rotating disk 908, so that the second rotating rod 907 carries the two-way rotating disk 908 to rotate idly, and after the meshing stroke of the toothed plate 914 and the gear 912 is completed, the corresponding arc-shaped stop blocks 910 will all be between the two arc-shaped inclined blocks 906;

[0053] Then, the electric telescopic rod 913 is raised and reset, so that the stud welding gun 6 carrying the mounting plate 3 is reset to the original height, and the stud welding gun 6 carrying the next stud 128 and located on the right side is automatically rotated to the front welding station;

[0054] The specific steps are as follows: after the welding of the stud 128 in the arc plate 8 clamped by the front stud and the plate 11 to be processed is completed, the operator needs to remove the energized clamp 7, and then reset the retracted height of the extended end of the electric telescopic rod 913. The resetting of the extended end of the electric telescopic rod 913 drives the toothed plate 914 and the equilateral tripod 915 to rotate. The equilateral tripod 915 will be disengaged from the mounting pad 3 as it is reset. After the equilateral tripod 915 is disengaged from the mounting pad 3, the toothed plate 914 will continue to rise and reset. At this moment, the toothed plate 914 will mesh with the gear 912 in the reverse direction, prompting the gear 912 to drive the second rotating rod 907 and the two-way turntable 908 to reverse. The reversal of the two-way turntable 908 drives several arc-shaped blocks 910 to reverse. The arc-shaped block 910 rotates in the opposite direction, and the arc-shaped block 910 rotates in the opposite direction to fit with the flat side surface of the arc-shaped inclined block 906 and drive the arc-shaped inclined block 906 to rotate in a circle. The arc-shaped inclined block 906 drives the first rotating rod 902 to rotate by driving the one-way rotating disk 904. The first rotating rod 902 synchronously drives the two bevel gears 903 to mesh with each other. The meshing of the two bevel gears 903 synchronously drives the rotating shaft 2 to rotate in a circle. The rotating shaft 2 synchronously drives the mounting pad 3 to rotate. When the reverse meshing of the tooth plate 914 and the gear 912 reaches the limit, the corresponding mounting pad 3 rotates the front stud welding gun 6 and the stud clamping arc plate 8 after stripping to the left through the extension plate 4, and rotates the right stud welding gun 6 and the stud clamping arc plate 8 carrying the stud 128 to the frontmost side.

[0055] S2, automatic segmented loading of studs 128: During the descent of the mounting plate 3 carrying a plurality of stud welding guns 6, the stud welding gun 6 rotates from the front side to the left side, and the unloaded stud clamping arc plate 8 at the bottom thereof simultaneously clamps and takes out the studs 128 corresponding to the internal position of the loading tray 126;

[0056] The specific steps are as follows: the stud welding gun 6 at the front side welds the stud 128 in the stud clamping arc plate 8 to the plate 11 to be processed, and after the material is removed and rotated to the left, when the mounting pad 3, the extension plate 4, the stud welding gun 6 and the stud clamping arc plate 8 are again moved downward by the electric telescopic rod 913, the stud clamping arc plate 8 rotated to the left and unloaded will press down on the stud 128 in the loading tray 126 by descending, and the two stud clamping arc plates 8 are expanded by pressing down, and the stud 128 is clamped and loaded synchronously. At this moment, the loading height of the stud 128 is not fully loaded;

[0057] The stud welding gun 6 is subsequently driven to rotate and move up and down by installing the backing plate 3, so that the clamped stud 128 is pressed into the inside of the stud clamping arc plate 8;

[0058] The specific steps are as follows: with the installation pad 3 rising again, the stud clamping arc plate 8 for loading the studs 128 will clamp the studs 128 and rise, and with the continued rotation of the installation pad 3, the left stud clamping arc plate 8 will rotate to the left rear side.
