[0035] Start the driving source three 25 to drive the grooving knife 26 to rotate at high speed, and start the driving source two 24 to drive the screw rod 22 to rotate. When the screw rod 22 rotates, it drives the moving part 23 to move left, thereby driving the driving source three 25 and the grooving knife 26 to move left.

When the screw rod two 27 rotates, it drives the moving part two 29 to move to the left, and drives the driving source five 210 and the grooving knife two 211 to move to the left. At this time, the grooving knife two 211 rotating at high speed opens a right angle groove B1 at the bottom end of the front side surface of the metal plate two B.

[0038] In other embodiments, the metal plates 1A and 2B may be manually grooved, and then the grooved metal plates 1A and 2B are stacked together so that the angle between the metal plates 1A and 2B is ninety degrees or other required angles, and the brazing material is placed in the grooves cut by the metal plates 1A and 2B, and finally the brazing operation is performed, thereby realizing T-shaped weldments with different welding angles to meet the needs of T-shaped weldments with different angles.

[0039] like Figure 1 , Figure 5 and Figure 6 As shown, the clamping mechanism 3 includes a clamping assembly and a sliding assembly. The clamping assembly is used to clamp the metal plate 2B and keep the metal plate 2B perpendicular to the metal plate 1A. The sliding assembly is used to control the movement of the clamping assembly along the left and right directions. The grooving mechanism 2 is arranged below the clamping assembly and is used to open a right-angle groove at the bottom end of the front side surface of the metal plate 2B.

[0040] Continue to refer Figure 1 , Figure 5 and Figure 6 As shown, the sliding assembly includes a screw rod 31 and a driving source 6 32, the screw rod 31 is rotatably connected to the frame 2 41, the driving source 6 32 is connected to the frame 2 41, the driving source 6 32 is a motor, the output shaft of the driving source 6 32 is connected to the screw rod 3 31, and the clamping assembly is connected to the screw rod 3 31;

[0041] The clamping assembly includes a clamping part 1 33, a telescopic part 34 and a clamping part 2 35.

The telescopic part 34 is connected to the clamping part 1 33, and the telescopic part 34 is a cylinder. The clamping part 2 35 is connected to the telescopic end of the telescopic part 34, and is used to clamp the metal plate 2 B and keep the metal plate 2 B in a vertical state with the metal plate 1 A.

[0042] The telescopic portion 34 is started to drive the clamping portion 2 35 to approach the clamping portion 1 33, and the metal plate 2 B is clamped by the clamping portion 2 35 and the clamping portion 1 33, and the metal plate 2 B is kept perpendicular to the metal plate 1 A. At this time, a right-angle groove B1 can be opened at the bottom end of the front side surface of the metal plate 2 B by the groove cutting mechanism 2. After the groove cutting of the metal plate 2 B is completed, the driving source 6 32 is started to drive the screw rod 3 31 to rotate. When the screw rod 3 31 rotates, it drives the clamping portion 1 33 to move to the left, so that the clamping portion 1 33 drives the telescopic portion 34, the clamping portion 2 35 and the metal plate 2 B to move to the left, until the bottom surface of the metal plate 2 B contacts the top surface of the metal plate 1 A, and the left and right end surfaces of the metal plate 2 B contact the metal plate 1 A. The left and right end surfaces of the metal plate A are aligned, and at this time, the groove A1 on the metal plate A and the right-angle groove B1 on the metal plate B are combined into a receiving groove for accommodating the solder. During this process, the solder is fed into the receiving cavity by the wire feeding mechanism 5, and finally the welding mechanism is used to weld at the receiving groove to melt the solder in the receiving groove. Under the effect of the inclined setting of the metal plate A and the metal plate B, compared with the welding method in the prior art of placing the metal plate A horizontally and the metal plate B vertically, the welding method of the present invention can make the molten solder more easily enter the gap between the metal plate A and the metal plate B, so as to enhance the connection strength between the metal plate A and the metal plate B.

[0043] like Figure 1 , Figures 7 to 9 As shown, the wire feeding mechanism 5 includes a guide rail 51, a threaded rod 52, a guide block 53 and an extrusion portion 54. The guide rail 51 is connected to the frame 11. The guide rail 51 is provided with a mounting groove 1 511, which is matched with the groove A1 and the right-angle groove B1. The guide block 53 is slidingly connected to the guide rail 51 in a limited position. The bottom of the guide block 53 is provided with a mounting groove 2 531, which is matched with the mounting groove 1 511, the groove A1 and the right-angle groove B1. A cavity 532 is provided in the guide block 53, and the extrusion portion 54 is slidably connected in the cavity 532. The threaded rod 52 is threadedly connected to the guide block 53, and one end of the threaded rod 52 extends into the cavity 532 and is rotatably connected to the extrusion portion 54.

[0044] Insert the solder into the second mounting groove 531 on the guide block 53, and screw the threaded rod 52 to squeeze and fix the solder in the second mounting groove 531 through the extrusion portion 54. Then, the guide block 53 is limitedly slidably connected to the guide rail 51 so that the bottom of the solder enters the first mounting groove 511.

[0045] First, place the solder into the second installation groove 531, and drive the extrusion part 54 to be in close contact with the solder by screwing the threaded rod 52, so that the solder is fixed on the guide block 53, and then the guide block 53 is limited and slid on the guide rail 51. At this time, the solder extends into the first installation groove 511. When the metal plate 1A moves to the guide rail 51, it stops moving so that the installation groove 1 511, the groove A1 and the right-angle groove B1 are located on the same straight line. When the metal plate 2B is close to the metal plate 1A, the guide block 53 is pushed by the metal plate 2B to move to the left, so that the guide block 53 drives the solder to enter the groove A1 at the top of the metal plate 1A. At this time, the guide block 53 is not separated from the guide rail 51, and the guide block 53 is guided by the guide rail 51 to prevent the guide block 53 from coming out The guide block 53 is now offset, and the solder enters the right-angle groove B1 at the bottom end of the front side surface of the metal plate 2 B. After the bottom of the metal plate 2 B contacts the top of the metal plate 1 A, the guide block 53 is separated from the guide rail 51, and the solder is limited in the groove A1 and the right-angle groove B1, thereby guiding and limiting the guide block 53. The metal plate 2 B continues to push the guide block 53 to move to the left. After the left and right sides of the metal plate 2 B are aligned with the left and right sides of the metal plate 1 A, the guide block 53 falls off the metal plate 1 A. At this time, the solder leaked out of the two ends of the metal plate 1 A is manually removed, and then the guide block 53 is reconnected to one end of the subsequent solder, and is limitedly slidably connected to the guide rail 51 to wait for the next welding between the metal plate 1 A and the metal plate 2 B.

[0046] In other embodiments, a certain length of solder may be directly inserted into the receiving groove formed by combining the groove A1 on the metal plate 1 A and the right-angle groove B1 on the metal plate 2 B.

[0047] When the metal plate 2B moves to the left, the guide block 53 is pushed to move to the left, so that the guide block 53 drives the solder to move to the left and enter the groove A1 at the top of the metal plate 1A. After the bottom of the metal plate 2B contacts the top of the metal plate 1A, the top of the solder is inserted into the right-angle groove B1 on the metal plate 2B. The solder is limited by the groove A1 on the metal plate 1A and the right-angle groove B1 on the metal plate 2B to prevent the solder from escaping from the groove A1 and the right-angle groove B1. After the left and right end faces of the metal plate 2B are aligned with the left and right end faces of the metal plate 1A, the solder completely enters the accommodating groove. At this time, the guide block 53 is separated from the metal plate 1A, and the staff can manually cut off the solder that leaks out of the two ends of the metal plate 1A, so that the metal plate 1A and the metal plate 2B can be welded by the welding mechanism later.

[0048] Working principle:

[0049] Place the metal plate A on the support portion 12 to tilt the metal plate A, and limit the metal plate A through two adjacent pushing portions 16, start the driving source 17 to drive the transmission between the transmission belt 15 and the two transmission rollers 14, so that the transmission rollers 14 drive multiple pushing portions 16 to move, and push the metal plate A on the support portion 12 through multiple pushing portions 16 to move the metal plate A to the cutting device 2. At this time, the top of the metal plate A contacts the bottom of the shielding portion 13. At the same time, a space for limiting the metal plate A can be formed by the two adjacent pushing portions 16 and the left and right sides of the inner wall of the frame body 11.

[0050] Start the driving source three 25 to drive the grooving knife 26 to rotate at high speed, and start the driving source two 24 to drive the screw rod 22 to rotate. When the screw rod 22 rotates, it drives the moving part 23 to move to the left, thereby driving the driving source three 25 and the grooving knife 26 to move to the left. At this time, a groove A1 is opened on the top surface of the metal plate A by the high-speed rotating grooving knife 26, and the groove A1 extends to the left and right ends of the metal plate A. After grooving, turn off the driving source three 25, and start the driving source two 24 again to drive the screw rod 22 to rotate. When the screw rod 22 rotates, it drives the moving part 23 to move to the right, so that the driving source three 25 and the grooving knife 26 move to the right and reset, and then start the driving source 17 again, and the pushing part 16 drives the metal plate A to move backward, so as to open a groove A1 on the top of the next metal plate A.

[0051] Place the metal plate 2B on the support 42 so that the metal plate 2B is tilted and the angle between the metal plate 2B and the metal plate 1A is a right angle, then insert the solder into the mounting groove 2 531 on the guide block 53, and screw the threaded rod 52 to squeeze and fix the solder in the mounting groove 2 531 through the extrusion part 54, then, the guide block 53 is limitedly slidably connected to the guide rail 51 so that the bottom of the solder enters the mounting groove 1 511.

[0052] Start the telescopic part 34 to drive the clamping part 2 35 to approach the metal plate 2 B, so that the metal plate 2B is clamped and fixed by the clamping part 2 35 and the clamping part 1 33, and then start the driving source 5 210 to drive the grooving knife 2 211 to rotate at a high speed, and start the driving source 4 28 to drive the screw rod 2 27 to rotate, and when the screw rod 27 rotates, it drives the moving part 29 to move to the left, and drives the driving source 5 210 and the grooving knife 2 211 to move to the left. At this time, the high-speed rotating grooving knife 211 opens a right-angle groove B1 at the bottom end of the front side surface of the metal plate 2B, and then close the driving source 5 210 to stop the grooving knife 211 from rotating, and start the driving source 4 28 to drive the screw rod 2 27 to rotate, and when the screw rod 27 rotates, it drives the moving part 29 to move to the right, and drives the driving source 5 210 and the grooving knife 2 211 to move to the right and reset.

[0053] Start the driving source six 32 to drive the screw three 31 to rotate. When the screw three 31 rotates, it drives the clamping part one 33 to move leftward, so that the clamping part one 33 drives the telescopic part 34, the clamping part two 35 and the metal plate two B to move leftward, until the bottom surface of the metal plate two B contacts the top surface of the metal plate one A, and the left and right end surfaces of the metal plate two B are aligned with the left and right end surfaces of the metal plate one A, and the rear end surface of the right-angle groove B1 on the metal plate two B contacts the rear end surface of the groove A1. At this time, the groove A1 on the metal plate one A and the right-angle groove B1 on the metal plate two B are combined into a receiving groove for accommodating the solder.

[0054] When the metal plate 2B moves to the left, the guide block 53 is pushed to move to the left, so that the guide block 53 drives the solder to move to the left and enter the groove A1 at the top of the metal plate 1A. After the bottom of the metal plate 2B contacts the top of the metal plate 1A, the top of the solder is inserted into the right-angle groove B1 on the metal plate 2B. The solder is limited by the groove A1 on the metal plate 1A and the right-angle groove B1 on the metal plate 2B to prevent the solder from escaping from the groove A1 and the right-angle groove B1. After the left and right end faces of the metal plate 2B are aligned with the left and right end faces of the metal plate 1A, the solder completely enters the accommodating groove. At this time, the guide block 53 is separated from the metal plate 1A, and the staff can manually cut off the solder that leaks out of the two ends of the metal plate 1A, so that the metal plate 1A and the metal plate 2B can be welded by the welding mechanism later.
