Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel processing equipment, in particular to a welding machine for stainless steel production and processing. Background Art

[0002] A welding machine is a device specially used for welding stainless steel materials. During the welding process, welding rods are used as filling materials. The high temperature of the arc is mainly used to melt the welding rods and the base material to form a molten pool. After cooling, the welding joint is connected. The advantages of this welding machine lie in its flexibility and adaptability. It can select welding rods of different diameters and materials according to different stainless steel materials and thicknesses to achieve the best welding effect; the welding machine mainly contacts the workpiece through the welding rod and is energized. The current is hindered at the contact point, generating resistance heat, and a certain gap is formed between the welding rod and the workpiece. At this time, the current passes through the gap to form an arc. The high temperature of the arc causes the welding rod and the workpiece to partially melt. The molten welding rod transitions to the surface of the workpiece in the form of molten droplets and mixes with the molten part of the workpiece; the ground wire is used to establish a welding circuit to ensure that the current can smoothly pass through the workpiece and return to the welding power supply. The current needs to form a closed loop through the workpiece, welding rod and ground wire to achieve welding. If the ground wire is missing, the current cannot form a complete loop, resulting in the inability to weld; and the ground wire ensures the insulation of the circuit and introduces the current into the ground through the ground wire, thereby protecting the safety of the operator. If the welding machine is not connected to the ground wire, the current may form a loop through the human body, causing serious electric shock hazards.

[0003] Patent CN207087117U discloses a welding machine, including a welding machine and a workbench, wherein a bracket is arranged on the workbench, a carrier fixedly connected to the welding machine is arranged on the bracket, a moving component for driving the carrier to move in a horizontal direction is arranged between the carrier and the bracket, a locking component for fixing the carrier on the bracket is arranged on the carrier, a rotating component is arranged between the bracket and the workbench, the rotating axis of the rotating component is arranged vertically, a winding component is arranged on the carrier, the winding component includes a winding wheel rotatably connected to the carrier, and a rotary spring is connected between the winding wheel and the carrier; although the above device solves the problem of adjusting the position of the welding gun.

[0004] However, the above technical solution still has the following problems:

[0005] When the material is placed on the operating table, it is not connected to the ground wire, and it is difficult to form a welding circuit between the material and the welding head. No current can be generated between the material and the welding head to achieve the effect of melting welding. When welding materials of different shapes, some special positions need to be welded, and the material cannot be rotated. Manual material handling is required during welding, which reduces work efficiency. There is no insulation protection between the welding material, the operating table and the ground wire, which is prone to electric shock hazards. Utility Model Content

[0023] like Figure 1 As shown, a stainless steel production and processing welding machine in the utility model is similar to the existing welding machine structure, such as the welding machine disclosed in the patent publication number CN207087117U. The main improvement of the utility model is that the welding material is easier to move during welding, such as Figures 1 to 5As shown, when a stainless steel production and processing welding machine in the utility model is in use, the stainless steel material is moved to the adjustment mechanism 4 on the surface of the machine base body 1 through the feeding roller 6, and the adjustment mechanism 4 is rotated to align the welding position of the stainless steel material with the sliding welding head 3, and one end of the stainless steel material is fixed by the clamping device 5, and the ground wire 7 in the clamping device 5 is connected to the stainless steel material, so that a welding circuit is formed between the ground wire 7, the stainless steel material, the sliding welding head 3 and the welding machine 2, and a high-temperature arc is formed between the surface of the stainless steel material and the sliding welding head 3, and the arc melts the molten droplet of the welding rod and combines it with the surface of the material to achieve a welding effect; the adjustment mechanism 4 allows the direction and angle of the stainless steel material to be adjusted, which is convenient for the sliding welding head 3 to weld, so that the sliding welding head 3 can weld the surface of the stainless steel material at more angles and directions, thereby improving the welding effect, and also helps the clamping device 5 to change the position of some stainless steel materials that are not easy to clamp, maintain the connection between the ground wire 7 and the stainless steel material, stabilize the high temperature of the arc, and improve the welding effect.
