Thus, by integrating the plasma head 210 into the automatic welder platen 400, the lifting mechanism 100, and the rotating mechanism 200 described above, the structure is simple, and automation of punching can be realized.

In an actual punching operation, the plate strip 500 to be welded is first positioned by an automatic welder, and the thickness of the plate strip 500 may be 6mm. Then, as shown in fig. 4 (fig. 4 shows the automatic welder platen 400 after pressing the strip, when the stand 101 is not lowered), the automatic welder platen 400 presses the plate strip 500. Next, as shown in fig. 5 (fig. 5 shows that after the platen 400 of the automatic welder presses the strip steel, when the stand 101 has been lowered), the elevating driving part is driven by the elevating driving part in the elevating mechanism 100 to drive the plasma head 210 to descend from the initial position to the punching position, and the distance between the plasma head 210 lowered to the punching position and the strip steel 500 can be maintained at 3mm.

Finally, the lifting driving component in the lifting mechanism 100 drives the lifting component to drive the plasma head 210 to lift to return to the initial position, as shown in fig. 2 (fig. 2 shows when the automatic welding machine pressing plate 400 does not press the strip steel), and after the actions such as welding and punching are completed, the automatic welding machine pressing plate 400 can return to the initial position. By cycling through the above steps, a number of sheet steel strips 500 may be plasma perforated. In the above-described actual punching operation of the strip steel 500, by setting the interval between the center of the motor joint 202 located on the connection plate 203 and the center of the knuckle bearing 204 in the vertical direction to 20mm, the length of the connection rod 205 to 305mm, the distance between the connection plate 203 and the center of the spherical hinge head 208 to 375mm, and the distance between the center of the spherical hinge head 208 and the upper surface of the strip steel 500 (i.e., the side near the plasma head 210) to 180mm, a hole having a diameter of about 16mm can be finally formed in the strip steel 500 in accordance with the actual punching operation described below. In addition, the current level of the current of the plasma head 210 may be adjusted according to the thickness of the plate strip 500, and the adjustment range of the current may be 45A to 165A. The size of the hole diameter of the final plasma hole can be adjusted by adjusting the center distance between the motor joint 202 and the knuckle bearing 204 on the connecting plate 203 or adjusting the length of the connecting rod 205. In this way, in the process of carrying out plasma punching on the plate strip steel 500, the loss of equipment accessories can be reduced, and the assembly requirement of equipment can be effectively reduced.

The automatic welding machine pressing plate 400 is used for pressing the plate strip steel 500, the lifting driving part is used for driving the lifting part to move along the length extending direction of the guide part, the rotating driving part and the fastening part in the rotating mechanism 200 are gradually close to the plate strip steel 500 to drive the plasma head 210 installed in the fastening part to be close to the plate strip steel 500, then the rotating driving part in the rotating mechanism 200 is used for driving the fastening part to rotate, the rotating fastening part can drive the plasma head 210 to rotate above the plate strip steel 500, the plasma head 210 is used for performing rotary motion to cut the plate strip steel 500, and after the plasma head 210 rotates for one circle, holes can be formed on the plate strip steel 500. In the process of punching the plate strip steel 500, the plasma head 210 does not need to be replaced, so that the loss is reduced, and the structure is simplified. Thereby achieving the technical effects of reducing loss and simplifying structure.

Finally, it should be noted that the above-mentioned embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same, and although the present invention has been described in detail with reference to examples, it should be understood by those skilled in the art that modifications and equivalents may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and all such modifications and equivalents are intended to be encompassed in the scope of the claims of the present invention.
