The invention discloses temperature rising type metal material low-pressure machining equipment. The equipment comprises a base. A vertical plate is fixedly mounted on the upper portion of the right end of the base. A first through hole is formed in the middle of the left side surface of the vertical plate. An outer square pipe is fixedly mounted in the first through hole. The left end of the outer square pipe is sealed. An inner square pipe is arranged in the outer square pipe. The inner side of the right end of the outer square pipe and the inner square pipe are fixedly connected in a sealedmode through a sealing piece. A plurality of uniformly-distributed second through holes are formed in the upper and lower side surfaces of the outer square pipe correspondingly. Piston plungers are arranged in the second through holes correspondingly. The inner ends of the piston plungers are fixedly connected with the inner square pipe through first elastic telescopic rods correspondingly. The lengths of the outer square pipe and the inner square pipe can be customized according to the length of a steel pipe needing to be quenched, and therefore, the inner wall of a long seamless steel pipecan be quenched; and the equipment is simple and exquisite in structure, low in manufacturing cost and convenient to operate, the steel pipe does not need to be moved during quenching, only an induction head and cooling equipment need to move, energy consumption is smaller, and the equipment is suitable for application and popularization.
