Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tungsten wires, and particularly relates to a multi-strand tungsten wire straightening device. Background Art
[0002] Tungsten wire is a fine wire made by forging and drawing tungsten bars. Its main uses are to manufacture lamp filaments and high-speed cutting alloy steels, and it is also used in optical instruments, chemical instruments, etc. In actual production of tungsten wire, tungsten wire is mainly used in electric light sources such as incandescent lamps and tungsten halogen lamps. The tungsten wire used as various luminous bodies in bulbs also needs to be doped with a small amount of oxides of potassium, silicon, and aluminum during the smelting process. This kind of tungsten wire is called doped tungsten wire, also known as 218 tungsten wire or non-sagging tungsten wire.
[0003] The filament of an accelerator is usually made of tungsten wire. The tungsten wire of the accelerator cannot have defects such as bending and needs to be straightened. Currently, tungsten wire straightening devices usually straighten tungsten wire at room temperature. Since tungsten wire is prone to breakage at room temperature, it is not conducive to the straightening operation of tungsten wire. Content of the Utility Model
[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a multi-strand tungsten wire straightening device, which can solve the problem that tungsten wire is prone to breakage at room temperature and is not conducive to the straightening operation of tungsten wire.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A multi-strand tungsten wire straightening device includes a bracket. A tungsten wire pressing seat is fixedly connected to the top of the bracket. A tungsten wire is clamped inside the tungsten wire pressing seat. A pulley is fixedly installed on the top of the bracket. The tungsten wire is slidably connected to the surface of the pulley.
[0006] Preferably, a quartz tube is fixedly connected to the surface of the bracket. The tungsten wire passes through the inside of the quartz tube.
[0007] Preferably, a plumb bob is fixedly connected to the lower end of the tungsten wire.
[0008] Preferably, an air inlet joint is fixedly connected to the lower end of the quartz tube, and an air outlet joint is fixedly connected to the upper end of the quartz tube.
[0009] Preferably, a nitrogen generator is fixedly connected to the surface of the bracket. The exhaust port of the nitrogen generator is communicated with the air inlet joint through an exhaust hose.
[0010] Preferably, a heating coil is arranged inside the quartz tube.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] (1) For this multi-strand tungsten wire straightening device, the nitrogen generator produces nitrogen and discharges the nitrogen into the interior of the quartz tube through the exhaust hose and the intake joint. The nitrogen inside the quartz tube gradually increases and squeezes out the oxygen inside through the exhaust joint. Thus, the tungsten wire is straightened in the oxygen-free quartz tube. At this time, the heating coil can heat the tungsten wire to complete the straightening process. The staff can heat and straighten the tungsten wire in an oxygen-isolated environment, preventing the tungsten wire from breaking and causing economic losses, which is more convenient for the staff to straighten the tungsten wire and ensures the safety of tungsten wire straightening.
[0013] (2) For this multi-strand tungsten wire straightening device, the staff first passes the tungsten wire through the tungsten wire pressing seat, then winds it around the surface of the pulley, and finally passes the tungsten wire through the quartz tube and hangs a plumb bob at the lower end of the tungsten wire. The tungsten wire is straightened by the plumb bob, the pulley and the tungsten wire pressing seat, avoiding the bending of the tungsten wire and improving the accuracy of tungsten wire straightening.
