The invention relates to an automatic centrifugal casting machine with 12 work-stations in a technical field of mechanical engineering. The machine of the invention comprises: a second motor, a reducer and a divided mechanism input end of a cam roller gear are connected through a coupling. A big plate is arranged on a main shaft, the shaft direction of which is fixed by a first lock bolt; a damping mechanism is also arranged on the main shaft; the main shaft is arranged on a front bearing seat and a back bearing seat, and the circle of the big plate is 12-sided boundaries used for arranging 12 centrifugal casting machines. The first motor is arranged on an end of the big plate and a pulley is arranged on a shaft between the tail part of the centrifugal machine and the shaft of the first motor. The power of the first motor is transmitted to the centrifugal casting machine through 3 triangle belts, and the power supply wire of the first motor goes to a ring-slipping mechanism through the inner holes of the main shaft, and the front part of the centrifugal casting machine is provided with a cylinder die. The automatic centrifugal casting machine with 12 work station greatly changes the working environment of the casting workers, reduces the working intensity of the workers, improves the safety factor of the heat working workers and meanwhile reduces the load of the staff and improves the quality and output of the products.

The invention discloses a tunnel drilling machine, relating to a drilling device at the top of a tunnel. The tunnel drilling machine mainly comprises a base, a frame, a transverse guide mechanism, a longitudinal feed mechanism, a drilling rod and a power mechanism for driving the drilling rod, wherein the longitudinal feed mechanism is arranged on the frame through the transverse guide mechanism, the drilling rod and the power mechanism are arranged at the top of the longitudinal feed mechanism, and the drilling rod can move in the vertical direction through the longitudinal feed mechanism. The tunnel drilling machine is lighter in weight and convenient to mount and detach in the tunnel, can be arranged on a track at any time for construction, and can be evacuated from a track area at any time so as to make a room for the track to facilitate the construction of other construction parties. During drilling, the horizontal part is connected with the vertical part through a gear, thus the drilling precision is higher.

The invention discloses an automatic shot blasting machine for the inner and outer walls of a large-diameter steel pipe. The automatic shot blasting machine comprises a frame, a steel pipe rotating system, a shot blasting mechanism, a shot circulating system and a dedusting system, wherein the steel pipe rotating system is adaptable to rotating of a plurality of large-diameter steel pipes through adjustment and is especially applicable to large-diameter steel pipes; the shot blasting mechanism is provided with altogether six shot blasting devices, with three shot blasting devices acting on the outer walls of the steel pipe while the other three acting on the inner walls of the steel pipe; the shot circulating system is used for cyclic utilization of steel shots; and the dedusting system is used for removing dust in the steel shots. Compared with traditional rust removal technology, the automatic shot blasting machine provided by the invention has the advantages of lower power consumption, smaller work amount, reduced usage cost and higher efficiency; the automatic shot blasting machine does not raise a great amount of dust, changes the working environment of workers and is benefit for health of the workers; and the automatic shot blasting machine has a wider application scope and is especially applicable to rust removal of large-diameter steel pipes.

The invention discloses a method for automatically assembling and producing fireworks. A conveyor belt (1) is adopted to convey a tube mold frame (2) to an automatic powder charging machine (3) for charging powder, to an automatic bead charging machine (4) for charging beads and to an automatic soil loader (5) for loading soil, and the one-bang loading process is finished. The load for the tube body (6) in the tube mold frame (2) is at least over one bang load, and the equipment for each bang load is positioned in each explosion-proof chamber (7) arranged in turn on one side of the conveyor belt. An input push device (8) of the tube mold frame is arranged outside the conveyor belt (1) outside the door of each explosion-proof chamber (7), and an output push device (9) of the tube mold frame is arranged in each explosion-proof chamber (7) corresponding to each input push device (8). The method for automatically assembling and producing fireworks can assemble 100 flash bangs totally, andprovides convenient labor-saving high-production efficiency equipment for the firecracker industry; and the equipment has the advantages of novel design, simple structure, convenient maintenance, lowcost and high production efficiency, and ends manual work for assembling flash bangs and beads.
