The pneumatic clamping type drilling tool comprises a lower housing, two sets of clamping and positioning mechanisms, a drill plate, an air cylinder and a lower driving lever. The rear of the drill plate is hinged to a connecting piece of a supporting plate while the front of the same is provided with two openings. Front ends of two supporting seats are hinged to two opening locking mechanisms. The drill plate is provided with drill bushings, two rectangular through holes are formed in positions, corresponding to two pressing pieces, of the middle of the drill plate, and lower end faces of the rectangular through holes are higher than or equal to those of the pressing pieces. Vertical positioning plates are arranged in the rear of the supporting seats and above the housing. The hinged drill plate is convenient to clean and replace, the positioning plates are accurate in positioning, and the drill plate provided with the rectangular through holes is fastened through the locking mechanisms after being covered, so that the drill plate is enabled to be closer to the surface of a work piece, and drilling accuracy can be guaranteed. The pneumatic clamping type drilling tool has the advantages of being compact in structure, accurate in positioning, high in processing accuracy and applicable to processing of products of different specifications.

The invention provides a core-lifting rotary type vibrating extrusion forming tubing machine. According to the core-lifting rotary type vibrating extrusion forming tubing machine, an automatic core lifting mode is adopted to an inner die, a special forklift demoulding mechanism is adopted to outer dies for quick die opening and die assembly, the outer dies can be quickly arranged in place through a rotary platform, and production efficiency is improved. The core-lifting rotary type vibrating extrusion forming tubing machine comprises a rack, a feeding mechanism, a rolling plate, the rotary platform, the outer dies, a rotary material uniforming mechanism, a vibrating mandrel and the inner die. The outer dies are arranged on the rotary platform which drives the outer dies to rotate, and the rotary platform is located above the inner die. The rotary material uniforming mechanism is arranged on the top of the inner die, the vibrating mandrel is arranged in the inner die, the inner die ascends and descends relative to the rack through a lifting mechanism, and the inner die enters the outer dies to form a tube cavity. The feeding mechanism is used for feeding materials to the tube cavity, the rolling plate is arranged on the rack and ascends and descends, and the rolling plate is used for rolling concrete products on the upper portion of the tube cavity. By means of the core-lifting rotary type vibrating extrusion forming tubing machine, auxiliary procedure time consumed in the production process is shortened, and work efficiency is improved.
