Pipe bending device for high-pressure cavity cover assembly

The invention discloses a pipe bending device for a high-pressure cavity cover assembly. The comprises a latching mechanism, a pipe bending mold, a device frame, an arc-shaped pipe bending wrench and a semicircular pipe bending wrench; the pipe bending mold is erected at the upper end of the device frame; the latching mechanism is installed at the upper left end of the pipe bending mold; the high-pressure cavity cover assembly is arranged above the pipe bending mold; the right upper end of the pipe bending mold cooperates with the arc-shaped pipe bending wrench; a first wrench hole is longitudinally formed in the lower portion of the front face of the pipe bending mold; a second wrench hole is transversely formed in the lower portion of the right side face of the pipe bending mold; and the semicircular pipe bending wrench is cooperatively arranged in the first wrench hole or the second wrench hole. The pipe bending device can complete clamping and bending of the high-pressure cavity cover assembly, and is hig
