The invention discloses an automatic flaring machine which comprises a machine base, a flaring fixed die assembly, a flaring movable die assembly, a flaring and stamping device and a positioning device, wherein the flaring movable die assembly is matched with the flaring fixed die assembly to clamp connection pipes; the flaring and stamping device is used for conducting flaring on the connection pipes; the positioning device can make the axes of the connection pipes coincide with the axis of a punch of the flaring and stamping device; the flaring fixed die assembly, the flaring movable die assembly, the flaring and stamping device and the positioning device are arranged on the machine base. According to the automatic flaring machine, the positioning device is additionally arranged, it is guaranteed that the axels of the connection pipes are collinear with the axis of the punch of the flaring and stamping device, and the flaring fixed die assembly and the flaring movable die assembly clamp the connection pipes; compared with the prior art that the connection pipes are manually positioned, positioning accuracy of the connection pipes is effectively improved, so that the percentage of pass of finished products is raised, and consistency of the finished products is improved; the production cost of the finished products is further lowered; meanwhile, automatic flaring is achieved, production efficiency is improved, and labor intensity is lowered.

The invention provides a self-oscillation type pulse cyclone supercharger. The self-oscillation type pulse cyclone supercharger comprises a shell, an air inlet adjusting pipe, a left end cover, a pulse cyclone blade, an air outlet adjusting pipe and a right end cover; a main air inlet and a main air outlet are formed in the left end and the right end of the shell correspondingly; the left end cover and the right end cover of the shell are fixed through an M8 screw; the pulse cyclone blade is arranged inside the shell; the air inlet adjusting pipe is installed at the left end of the pulse cyclone blade; the air outlet adjusting pipe is installed at the right end of the pulse cyclone blade; two supporting leg bases are welded to the shell; the pulse cyclone blade comprises a center sleeve pipe and a cyclone blade arranged at the concave portion of the center sleeve pipe; particles and gas in the center sleeve pipe flow in the axial direction; a pulse cyclone air flow is formed between the shell and the pulse cyclone blade; and an auxiliary supplementing air inlet is formed in the shell and is in G1 pipe threaded connection. The self-oscillation type pulse cyclone supercharger is wide in application range, can reduce the minimum conveying speed of the particles, relieve the pipe abrasion, reduce particle crushing and avoid pipe blockage, and is suitable for pneumatic long-distance conveying of material particles.

The invention discloses a rapid filament feeding device used for FDM type 3D printing material filaments. The rapid filament feeding device comprises at least one feeding mechanism. Each feeding mechanism comprises a base located between a feeding tank and a spray nozzle. A rail is arranged on each base. Two slide blocks are arranged on each rail in a sliding manner. A first drive device is arranged on each slide block. The output end of each first drive device is connected with a wire feeding disc through a first rotating shaft. The first drive devices are used for driving the wire feeding discs to rotate. The gap between every corresponding wire feeding discs is matched with the diameter of wire rods. After the diameter of the to-be-conveyed wire rods is confirmed, the relative positions, on the rails, of the slide blocks are adjusted, the gap between every two corresponding wire feeding discs is then changed, the gap is made to be matched with the diameter of the to-be-conveyed wirerods, and the situation that after the diameter of the wire rods is changed, the wire rods get stuck or cannot be conveyed is avoided; and meanwhile, universality of the filament feeding device is improved, and the rapid filament feeding device can meet wire rod diameter requirements under different working conditions.

The invention discloses a liquid guide device and method for stabilizing and controlling flow in a magnesium alloy semi-continuous casting process, belonging to the field of casting. The liquid guide device for stable flow control in the semi-continuous casting process of magnesium alloy is provided with a liquid guide control actuator and a protective gas control device; The device is used to adjust and control the rise and fall of the shunt device, and the control shunt device is used to control the flow rate of the magnesium alloy melt at the liquid end of the catheter; the crucible containing the magnesium alloy and the protective gas storage tank are connected through the protective gas pipeline, and the protective gas pipeline There is a shielding gas control device on it, which is used to control the pressure inside the crucible by adjusting the shielding gas output flow. The device can stably transmit the high-temperature melt during the semi-continuous casting process, ensure the stability of the liquid level in the mold, improve the surface quality and smoothness of the product, reduce the possibility of slag inclusion, and realize stable and safe casting production. wide.
