Example Embodiment

[0021] Example one

[0022] Such as Figure 1 to 2 As shown, an automatic coiling method of welding rods in an electrode box of a submerged arc welding machine of the present invention includes a workbench 1, and also includes a wire crimping device connected to the workbench, and a wire placement device located on both sides of the wire crimping device. The line device and the standard line box 4; the pay-off device and the standard line box 4 are connected to the workbench 1 or the line pressing device, the axis of the standard line box 4 and the horizontal plane form an angle β, and 0

[0023] The crimping device includes two parallel sections connected to the workbench 1 and a pressure roller gantry 12 perpendicular to the workbench 1, a pressure roller 5 and a driving wheel 6 placed between the two pressure roller gantry 12 ; The driving wheel 6 is located directly below the pressure wheel 5, and the driving wheel 6 is connected with a driving mechanism 7. The driving wheel 6 pulls the submerged arc welding wire derived from the pay-off device, and the arc welding wire is squeezed between the pressing wheel 5 and the driving wheel 6 to become a straight welding wire. The rotation of the pressing wheel 5 and the driving wheel 6 removes the arc of the submerged arc welding wire and leads it out of the wire coil on the pay-off device.

[0024] The driving mechanism 7 is a motor. The driving wheel 6 is driven to rotate clockwise by the motor through a belt or a chain, and the submerged arc welding wire moves to the standard wire box 4. The friction between the pressure wheel 5 and the submerged arc welding wire pushes the pressing wheel 5 against It rotates in the clockwise direction. Therefore, in the process of squeezing the welding wire, manpower input is reduced and the coiling process is automated.

[0025] The pressing wheel 5 and the driving wheel 6 are both radially concave to form a limit groove 8. In order to prevent the position of the submerged arc welding wire from being offset when being squeezed by the pressing wheel 5 and the driving wheel 6, a curvature is generated. The wheels 6 are radially inwardly concave at the same position to form a limiting groove 8.

[0026] The depth of the limiting groove 8 is smaller than the radius of the welding wire. In order to ensure that the submerged arc welding wire derived from the pay-off device can be squeezed by the driving wheel 6 and the pressing wheel 5, the depth of the limit groove 8 must be less than the radius of the submerged arc welding wire, and the total depth of the two limit grooves 8 It needs to be smaller than the diameter of the submerged arc welding wire. Only in this way can the arc of the submerged arc welding wire be effectively removed.

[0027] The pay-off device includes an upright 2 connected to the workbench 1 and a tray 3 fixedly sleeved on the upright 2. The diameter of the column 2 is smaller than the core diameter of the large coil of submerged arc welding wire, and the welding wire coil can rotate around the column 2. The tray 3 holds up the welding wire coil to avoid contact with the ground and reduce friction.

[0028] The standard wire box 4 is connected to the workbench 1 through a bracket 9. The top of the bracket 9 is provided with a rotating shaft, and the standard wire box 4 is sleeved on the rotating shaft. There is a through hole in the center of the standard wire box 4, which is convenient to be placed on the submerged arc welding machine to rotate and take the welding wire. Similarly, when the submerged arc welding wire is introduced, the standard wire box 4 rotates on the rotating shaft at the top of the bracket 9 to reduce the wire coiling. When the linear submerged arc welding wire is introduced into the standard wire box 4, since the axis of the standard wire box 4 is at an angle with the horizontal plane, the motor drives the driving wheel 6 through a belt or chain to rotate smoothly to move the submerged arc welding wire to the standard wire box. 4 Move, the force of the submerged arc welding wire on the standard wire box 4 acts on the side wall of the standard wire box 4. The force is decomposed into the tangent direction of the standard wire box 4, and the perpendicular and tangential direction, along the tangent direction of the standard wire box The component force of φ pushes the standard wire box 4 to rotate around the rotating shaft, and the component force in the vertical and tangential directions causes the submerged arc welding wire to bend and automatically coil.

[0029] An introduction pipe 10 connected to the workbench 1 is provided between the crimping device and the payoff device, and an outlet pipe 11 connected to the workbench 1 is provided between the crimping device and the standard wire box 4. The introduction pipe 10 introduces the arced submerged arc welding wire derived from the pay-off device into the limiting groove 8 on the driving wheel 6 and the pressing wheel 5 of the wire crimping device after preliminary deformation, and the submerged arc welding wire is passed through the crimping device After that, it is a straight wire, which is led into the cavity of the standard wire box 4 through the outlet pipe 11. After the welding wire contacts the side wall of the standard wire box 4, under the force of the driving wheel 6, the submerged arc welding wire runs along the standard wire box 4 The side wall of the wire is bent, and after the standard wire box 4 is rotated, the welding wire automatically coils.
