The utility model relates to a pressing device for damping sound insulation board production, which belongs to the technical field of damping sound insulation board production and comprises a workbench and a mounting top plate arranged at the top of the workbench, and a linkage pushing mechanism convenient for workers to load and unload is arranged between the workbench and the mounting top plate. According to the pressing device for damping sound insulation board production, a telescopic air cylinder is arranged to drive a connecting plate and a lower pressing plate to move downwards, then a fixing base and a mounting frame are arranged, so that the lower pressing plate can extrude a rolling wheel, the mounting frame is driven to rotate clockwise, then the mounting frame rotates to drive a rotating plate to rotate, and through arrangement of a movable block and a movable groove, the rotating plate can rotate clockwise; and meanwhile, a connecting plate drives a pressing plate to move downwards, so that the sound insulation plate can be subjected to pressing treatment, the situation that the hands of a worker are located at the bottom of the pressing plate can be avoided, and the safety of the worker is improved.

This invention discloses a superconducting melting device that uses a permanent magnet hollow motor to drive a low-temperature superconducting coil, belonging to the technical field of metal melting equipment. It includes a support base with a rotating connecting seat fixedly connected to its top. Through the linkage between the hollow motor and the low-temperature superconducting coil, when the hollow motor drives the hollow motor rotor to rotate, the rotor drives the low-temperature superconducting coil to rotate synchronously. The low-temperature superconducting coil directly generates a dynamic rotating magnetic field, which in turn forms a uniform rotating magnetic field inside the melting crucible. This rotating magnetic field directly acts on the stationary metal ingot, causing it to generate induced eddy currents and self-heat, melting it. Through the synergistic effect of the hollow motor and the low-temperature superconducting coil, the metal ingot can complete the transformation from solid to liquid in a completely non-contact state, avoiding the impurity introduction problem caused by direct contact between electrodes, crucibles, and other components and the molten metal in traditional melting methods. This achieves clean melting of highly active, high-purity metals.

The utility model provides an anti -explosion safety type motor belongs to motor field, including shell, motor stator, motor rotor and pivot, motor stator, motor rotor and pivot are in order to be installed in the inside of shell, the one side of shell is provided with the heat dissipation explosion -proof mechanism for conducting and discharging heat, the one side of shell is provided with the wire harness assembly that separates the cable of shell inside. The utility model discloses the heat dissipation explosion -proof mechanism that sets up, realized the effect that the heat that produced in the inside of shell is conducted and blows away, when using, motor stator generates magnetic force, and then produces rotating magnetic field, makes motor rotor and pivot rotate, and the one end of the pivot at the front end cover when rotating can drive external equipment to rotate, and the one end at the rear end cover will drive the rotation of the fan blade, and the heat in the inside of shell is blown out of the shell through the dust cover, reduces the heat in the inside of shell, prevents the heat combustion.
