a limiting block is arranged at the top end of the guide rod and used for controlling the position of the lifting plate in the height direction;
in the specific implementation process, the die body synchronously moves under the condition that the rotating shaft rotates, when the die body rotates to pass through the push rod, two sides of the push rod slide along the sliding grooves arranged on the inclined rod, the push rod also pushes the guide rod, the lifting plate, the vertical plate and the movable head to synchronously move, the distance between the movable head and the die body is regulated, and in order to ensure that the distance between the movable head and the die body is constant, the shape of the contact surface of the push rod needs to be adaptively changed in actual use;
the lifting plate is composed of a transverse plate and inclined plates symmetrically arranged at two sides of the transverse plate;
an elastic supporting piece is arranged at the top end of the transverse plate, and the top end of the elastic supporting piece is fixedly connected with the bottom end of the top plate;
the inclined plate is fixedly connected with the guide rod, and the elastic supporting piece is elastically deformed when the lifting plate is lifted by force;
the air supply system is arranged on the constant distance adjusting mechanism, and the bottom end of the air supply system is communicated with a filling port arranged on the L-shaped rod;
the air supply system comprises an air delivery pipe and a second flow passage;
the second flow passage is arranged in the vertical plate, and the gas transmission pipe is arranged on two sides of the vertical plate and communicated with the second flow passage;
the second flow passage is communicated with the movable head so as to facilitate the flow of the nitrogen-containing gas;
the air supply system also comprises a first runner and a spray hole;
the spray holes are uniformly distributed in the length direction of the top end of the L-shaped rod;
the first runner is arranged in the L-shaped rod, and the spray hole is arranged on the inner side of the L-shaped rod and communicated with the first runner;
the direct-current voltage is arranged between the die body and the movable head, so that ionized gas components can be conveniently accelerated to impact the surface of the die body to heat the die body, and meanwhile, the nitriding treatment is carried out by means of sputtering and ionization.
