Problems solved by technology

[0005] Although the quality of the white wire obtained by the above electrolysis method is improved and the surface quality is good, the size fluctuation of the wire is usually above 0.1mm, which cannot meet the needs of customers with a size tolerance range of <0.1mm
[0006] In addition, the size of the existing wire is spot-checked after the cleaning process is completed. After the size is found to be out of tolerance, the wire size is controlled by adjusting the wire drawing rate during cleaning. This size control method, once the size is found to be out of tolerance When the wire has been cleaned, the wire that exceeds the upper limit must be cleaned again, and the wire that exceeds the lower limit cannot be remedied.

Abstract

The invention provides a machining device for controlling the size of a tungsten molybdenum wire. The machining device sequentially comprises the following components of a pay-off wheel, a tension adjusting component, an electrolytic cell, a cleaning tank, a drying component, a wire guide wheel, a size measuring instrument and a wire collecting wheel, and further comprises an electrolysis power supply, a controller and a current tester, wherein the input end of the current tester is connected between an electrode cathode of the electrolytic cell and the electrolysis power supply, and the output end of the current tester is electrically connected with the input end of the controller; the output end of the size measuring instrument is electrically connected with the input end of the controller; and the output end of the controller is connected with the current adjusting component of the electrolytic cell. By adopting the machining device, the measuring instrument sends the measured sizeto the controller, when the size fluctuates, the controller outputs a control signal to adjust the electrolysis current, and the size tolerance range of the wire is extremely small ((0.1mm) through accurate control over the electrolysis current, so that the requirements of customers are met, the primary unqualified rate of the wire is greatly reduced, the production efficiency and the input-outputof the wire are improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of tungsten-molybdenum wire preparation, and in particular relates to tungsten-molybdenum wire processing equipment and a method for controlling the size of tungsten-molybdenum wire. Background technique [0002] Scheelite (molybdenum) wire is black tungsten (molybdenum) wire after alkali washing, hydrogen sintering or electrolysis. Compared with black tungsten (molybdenum) wire, the surface of scheelite (molybdenum) wire is smooth, bright and clean. Silver-gray metallic luster, uniform wire diameter, good processing and forming performance, long filament life and high luminous efficiency. It is widely used in the electric vacuum industry to produce various types of electron tubes. Filaments for H series automotive lamps, halogen lamps and other special bulbs produced in the electric light source industry. [0003] Patent CN201010258482.2 discloses a device for continuously cleaning the surface of molybdenum wire at...
