This utility model discloses a melting and casting device for recycling Babbitt alloy from a pear-shaped steel wire rope sheath. It includes a housing, a medium-frequency induction furnace housed within the housing, and a casting mold. The medium-frequency induction furnace comprises a furnace body, a capacitor box, and a power supply box. The furnace body has a hollow structure extending vertically, with a lifting port at the top and an open bottom. The furnace body is designed with three layers from the outside in: an outer layer of heat insulation plate, a middle layer of induction coils arranged in a spiral pattern using hollow copper tubes, and an inner layer of fireproofing mud. The power supply box is electrically connected to the capacitor box and the induction coils. The casting mold is located below the furnace body. Eddy currents are generated inside the pear-shaped steel wire rope sheath suspended in the furnace by the induction coils, generating heat to heat the sheath. When the heating temperature exceeds 230°C, the Babbitt alloy inside the sheath melts rapidly, forming a flowing liquid that drips directly into the casting mold below. Finally, it cools and is demolded, achieving effective recycling of the alloy.

This invention discloses a laser cutting device for CNC machining equipment, relating to the field of CNC laser cutting technology. It includes a cutting device body, comprising a laser cutting head; and a processing mechanism mounted on the cutting device body, comprising: a cooling shroud fixed to the cutting device body and fitted onto the laser cutting head, the cooling shroud having vents arranged in a circumferential array; and an air shroud fixedly fitted onto the cooling shroud. This invention uses a linkage between a cooling component and a fume extraction component. High-temperature flue gas is pre-cooled by the cooling shroud before filtration, preventing damage to soft pipes from high temperatures and extending the lifespan of the pipes and fume extraction components. Metal particles in the flue gas are collected by a collection frame and filter. After shutdown, a switching component automatically switches the pipes, using the airflow from the fume extraction component to blow residual coolant in the cooling shroud back to the liquid tank, completely preventing pipe scaling and blockage, and maintaining long-term stable heat exchange efficiency of the cooling system.

The utility model relates to a kind of double-shutter UV curing lamps with air cooling and liquid cooling, including outer shell, the inside of outer shell is provided with mounting cavity, UV lamp tube and shutter mechanism are provided in mounting cavity, shutter mechanism includes two shutters and the drive transmission assembly of driving the movement of two shutters;Liquid cooling plate is also provided in mounting cavity, liquid cooling plate is surrounded with two shutters in the outer periphery of UV lamp tube;The left and right sides of liquid cooling plate are respectively provided with first liquid channel, second liquid channel is respectively provided in two shutters;The outside of outer shell is connected with the air extraction pipeline communicated with mounting cavity. By surrounding liquid cooling plate and two shutters in the outer periphery of UV lamp tube, and liquid cooling plate and shutter are flowed with cooling liquid, most of the heat generated by UV lamp tube is absorbed by cooling liquid and taken away, and air extraction pipeline is connected on the outside of outer shell, air extraction pipeline takes away part of heat while air is extracted, further strengthen the cooling effect of UV curing lamp.
