It solves the problem raised in the above background technology that when welders use the special mold for flange welding, they often need to use screws to fix the steel pipe, which makes the welding steps too complicated. In addition, it is not easy to quickly position the flange during the positioning of the flange, and positioning needs to be performed multiple times, which increases the labor intensity of the welders and affects the work efficiency of welding the flange.

[0005] To achieve the above purpose, the utility model is implemented through the following technical scheme: a special mold for flange welding, including a cavity plate, a measuring rod is slidably connected inside the cavity plate, a clamping plate is hinged in the middle of the bottom surface of the cavity plate through a hinge, one side of the two clamping plates is fixedly connected to a lap plate, the bottom of the lap plate is fixedly connected to a spring, the bottom of the spring is fixedly connected to a connecting plate, a cavity is opened inside the clamping plate, and a guide component is slidably connected inside the cavity.

[0006] Optionally, the guide assembly includes a guide plate disposed inside the clamping plate, and a magnet block is embedded at one end of the guide plate.

[0007] Optionally, a slide groove is provided on the top surface of the clamping plate, a push block is slidably connected inside the slide groove, and the bottom of the push block is fixedly connected to one side of the top surface of the clamping plate.

[0008] Optionally, a handle is fixedly connected to the middle of the cavity plate surface, and an anti-slip film is attached to the outer surface of the handle.

[0009] Optionally, a shock-absorbing piston rod is sleeved inside the spring, and a semi-arc block is fixedly connected to one end of the clamping plate.

[0010] Optionally, both sides of the handle surface are fixedly connected with anti-slip rings, and the material of the anti-slip rings is rubber.

[0011] Optionally, a through threaded hole is opened on one side of the top surface of the cavity plate, and a blocking bolt penetrates the internal thread of the threaded hole.

[0012] The utility model provides a special die for flange welding, which has the following beneficial effects:

[0013] 1. The flange welding special mold is set up with a clamping plate, a spring and a hinge. When the welder needs to weld the steel pipe and the flange, the welder can set up the required steel pipe in advance, and use the clamping plate to clamp it to the top or bottom of the steel pipe and press it, so that the semi-arc block slides on the surface of the steel pipe, and then the clamping plate moves to both sides, and its lap plate drives the spring to move downward, so that the clamping plate opens to fix the steel pipe, thereby facilitating the staff to clamp and fix the steel pipe.
