Abstract: A device and method for adjusting a fuel supply advance angle of a multi-cylinder diesel engine includes a gear chamber, a connecting disc and a fuel pump, wherein the gear chamber and the connecting disc are in the diesel engine, and the fuel pump is at a left end surface outside the gear chamber. A main shaft end of the fuel pump extends into the gear chamber. A right end surface of the connecting disc connects to a timing gear. A right end surface of the timing gear has three penetrating circular-arc waist-shaped holes. Annular sizing blocks are arranged on the waist-shaped holes. A penetrating circular hole is at a tail end of the waist-shaped holes. The circular hole is provided with a T-shaped nut. A support screw is arranged in the T-shaped nut, and the screw head of the support screw is jacked against the annular sizing block.

Abstract: A bending mold device for bidirectional pipe bending includes a mounting base which is horizontally arranged on a rack in a sliding manner. The mounting base includes a translation lead screw driving the mounting base to slide. The rack includes a lead screw nut. A pipe bending spindle is rotatably disposed on the mounting base and a power mechanism is disposed on the mounting base. The upper end of the pipe bending spindle is movably connected to a lower rotating base. The lower rotating base includes a first pipe bending shaft and a second pipe bending shaft, which respectively include a first bending mold lower mold and a second bending mold lower mold. The rack includes a cylinder above the lower rotating base. The end part of a piston rod of the cylinder fixedly includes an upper limiting plate and a lower limiting plate in a sleeving manner.
