Description

Technical Field

[0001] The invention belongs to the technical field of plasma arc welding, and in particular relates to a plasma arc welding machine used for processing fan steel plates. Background Art

[0002] Plasma arc welding machine is a welding machine that uses plasma arc to melt metal for non-melting electrode or melting electrode welding. Plasma arc is a high-temperature gas flow generated by ionized ion gas, which is ejected from the nozzle hole and compressed to form a slender arc column. The high energy density beam is used to weld plates.

[0003] The principle of plasma arc welding makes it different from ordinary welding in that when welding materials of different thicknesses, it is necessary to adjust the distance between the welding gun and the surface of the material according to the thickness of the material, so as to adjust the size of the weld pool generated during the welding process and achieve the best welding effect. However, the traditional fan steel plate plasma arc welding device cannot monitor and adaptively adjust the distance between the plasma arc welding gun and the surface of the fan steel plate. As a result, during the welding process of fan steel plates of different thicknesses, the height of the welding gun needs to be manually adjusted and manually measured to achieve the best final welding effect.

[0004] After searching, in the prior art, the authorized patent with announcement number: CN220073533U and announcement date: 2023.11.24 discloses a plasma arc welding device, including a base, a rotating mechanism, a welding mechanism, and a clamping mechanism, wherein a first slot is provided in the middle of the front surface of the base, a U-shaped bracket is fixed to the left and right ends of the upper surface of the base, a support block is fixed to the left and right sides and the upper end of the rear side of the base, and a welding mechanism is provided at the upper end of the support block, a welding box is connected to the rear end of the upper surface of the base, and a third slot is provided at the lower end of the welding box, and a clamping mechanism is provided inside the third slot. The plasma arc welding device is provided with a clamping mechanism, and the electric push rod is opened, so that the upward movement of the electric push rod drives the rotation of the second rotating rod. Due to the rotating structure of the pressure column and the first rotating rod and the second rotating rod, the upward lifting of the second rotating rod drives the rotation of the pressure column and the first rotating rod, and then the pressure column is pressed downward against the upper surface of the metal steel, which is convenient for fixing the metal steel.

[0005] However, the device still has the following defects: it is unable to monitor and adaptively adjust the distance between the plasma arc welding gun and the surface of the fan steel plate, so that during the welding process of fan steel plates of different thicknesses, the height of the welding gun needs to be manually adjusted and manually measured to achieve the best final welding effect.

[0035] The plasma arc welding machine for processing fan steel plates proposed by the present invention has the following working principle: The fan steel plate to be welded is placed on the processing table 1, and the pressure plate 19 is driven downward by the electric cylinder 18 to limit and fix the fan steel plate to be processed. According to the position where welding is required, the processing component 9 drives the plasma arc welding gun 306 to move to the top of the starting position of the weld through the cooperation of the first motor 10 and the electric slide 2. Through the tension of the two groups of square springs 9018, a resistance force is generated on the two groups of floating blocks 9017, thereby generating resistance to the adjustment mechanism 902, so that the ball at the bottom end of the second annular block 9022 is attached to the surface of the fan steel plate to improve the stability of welding.

[0036] The distance between the welding end of the plasma arc welding gun 306 and the surface of the fan steel plate is preset according to the thickness value of the fan steel plate, and the preset value of the distance between the corresponding mounting block 903 and the second annular block 9022 is obtained. The distance between the mounting block 903 and the second annular block 9022 is monitored by the ranging infrared receiver 905 and the ranging infrared transmitter 904 and the data is fed back to the controller 304.

[0037] Through the direct meshing relationship between the driving gear 90214, the inner gear ring 9023 and the plurality of driven gears 9025, the rotation speed and rotation direction of the plurality of threaded rods 9026 are kept consistent, so that the mounting block 903 can move up and down while remaining stable, so that the plasma arc welding gun 306 installed in the mounting groove 9031 can move up and down synchronously while its welding end remains perpendicular to the surface of the fan steel plate to improve the welding effect.

[0038] Through the tension of two sets of square springs 9018, when replacing fan steel plates of different thicknesses, the adjustment mechanism 902 can be attached to the surface of the fan steel plate, so that the distance between the ranging infrared receiver 905 and the surface of the fan steel plate remains constant. Therefore, when the height of the mounting block 903 is adjusted, the change in the distance between the mounting block 903 and the adjustment mechanism 902 is equal to the change in the distance between the welding end of the plasma arc welding gun 306 and the surface of the fan steel plate, thereby making the adjustment of the distance between the welding end of the plasma arc welding gun 306 and the surface of the fan steel plate more precise.

[0039] The first motor 10 drives the screw rod 8 to rotate, so that the processing component 9 drives the plasma arc welding gun 306 to move longitudinally, and the welding operation is performed on the longitudinally distributed fan steel plate welds. The electric slide 2 drives the plasma generating mechanism 3 and the processing component 9 to move horizontally, so that the plasma arc welding gun 306 moves horizontally, and the welding operation is performed on the horizontally distributed fan steel plate welds.

[0040] The worm 15 is driven to rotate by the second motor 16, so that the worm wheel 4 drives the rotating table 5 to rotate synchronously to a preset angle value, and the lead screw 8 is driven to rotate by the first motor 10, so that the processing component 9 drives the plasma arc welding gun 306 to move along the angle value for welding operation, and the lead screw 8 is driven to rotate by the first motor 10, so that the processing component 9 moves to a preset position and then closes, and the worm 15 is driven to rotate by the second motor 16, so that the worm wheel 4 drives the rotating table 5 to rotate, so that the processing component 9 drives the plasma arc welding gun 306 to weld the arc weld of the fan steel plate.
