Description

Technical Field

When welding thicker metal plates, due to the larger cross-section of the weld, direct welding is not strong enough, and it is often necessary to cut the welding surface into an inclined surface so that the two metal plates form a V-shaped groove. Arc welding can be performed in the V-shaped groove to greatly improve the strength of the weld. The V-shaped groove is narrow at the bottom and wide at the top. When welding, the electrode needs to be welded in different welding curves according to different positions. The bottom layer can be welded by moving the electrode in a straight line, the middle layer is welded in a spiral line, and the upper layer continues to be welded through a back-and-forth swinging curve, so that the V-shaped groove is firmly arc welded in a layered manner.

[0035] See also Figure 1-Figure 12 , this implementation includes the following steps:

[0036] S1: First, the flux 112 and the iron core 129 are passed through the cylinder 128, and the upper end of the iron core 129 is clamped by the conductive clamp 133. The spring 140 can process the conductive clamp 133 to firmly clamp the connecting plate 120 to prevent it from slipping. Then, the second electric slide rail 110 is started by the controller 113. The second electric slide rail 110 drives the second slider 134 to move up and down, and the second slider 134 drives the connecting frame 130 to move up and down, thereby driving the iron core 129 and the flux 112 to move up and down. During the movement, the spring frame 137 will rotate, and the rotating frame 122 on the lower side will also rotate for adjustment, so as to adjust the flux 112 and the iron core 129 to a suitable arc welding angle;

[0037] S2: Then the electric push rod 109 drives the first slider 111 to move backward, and the first electric slide rail 107 drives the rotating frame 122 to move backward at the same speed, so that the lower side of the coating 112 and the iron core 129 are aligned with the lowermost layer of the rear end of the V-shaped groove to prepare for welding;

[0038] S3: When welding starts, the controller 113 controls the power supply 115 to transmit the current to the conductive clamp 133 through the transmission line 119, and then flows to the iron core 129. An arc is generated between the lower side of the iron core 129 and the welding workpiece 106. The welding workpiece 106 and the iron core 129 are welded by melting the welding workpiece 106 and the iron core 129 at high temperature. The coating 112 generates a protective gas. At the same time, the coating 112 is driven forward by the first electric slide rail 107 and the electric push rod 109 to perform linear arc welding on the bottom layer of the V-shaped groove. Due to the continuous loss of the coating 112 and the iron core 129, the speed of the first slider 111 driven by the electric push rod 109 is slower than the speed of the rotating frame 122 moving forward, so that the coating 112 and the iron core 129 move downward relatively in the cylinder 128, and are continuously replenished until the welding is completed.

[0039] S4: When welding the middle layer and the upper layer, the first bidirectional slide rail 124 and the second bidirectional slide rail 131 are started through the controller 113, the first bidirectional slide rail 124 drives the connecting rod 127 to move left and right, the connecting rod 127 drives the cylinder 128 to move left and right, and at the same time, the second bidirectional slide rail 131 drives the second sliding rod 136 to move left and right, the second sliding rod 136 drives the second slide plate 132 and the conductive clip 133 to move left and right, thereby driving the coating 112 and the iron core 129 to move left and right, and with the relative movement of the coating 112 in the cylinder 128, the spiral arc welding in the middle layer of the V-groove can be realized, and at the same time, the arc welding of the swinging route of the uppermost layer of the V-groove can be realized by driving the coating 112 and the iron core 129 to swing left and right alone, thereby realizing layered arc welding and improving the firmness of welding.
