Embodiment 1

[0018] Example 1: Set the atmospheric atmosphere resistance heating furnace to 400°C and then send electricity to raise the temperature; after the furnace temperature reaches the set temperature, continue to keep warm for 30 minutes; open the furnace door and place the niobium wire in the central area of ​​the furnace; close the furnace Door, keep warm for about 12 minutes after the temperature in the furnace returns to the set temperature; power off the heating furnace; open the furnace door, the wire comes out of the furnace; carry out stamping.

Embodiment 2

[0019] Example 2: Set the atmospheric atmosphere resistance heating furnace to 420°C and then send electricity to raise the temperature; after the temperature of the heating furnace reaches the set temperature, continue to keep warm for 30 minutes; open the furnace door, and place the niobium-1% zirconium alloy wire into the furnace Central area; close the furnace door, and keep warm for about 8 minutes after the temperature in the furnace returns to the set temperature; power off the heating furnace; open the furnace door, and the wire comes out of the furnace; carry out stamping.

[0020] According to calculations, the pass rate of blind hole parts stamped by the method of the present invention can reach more than 95%, which is nearly 50% higher than the pass rate of bare metal bars directly stamped, which greatly improves the difficulty of stamping and demoulding and the surface of stamping parts. The problem of easy straining improves the pass rate of stamping parts.

Abstract

The invention provides a method for processing a guide tube for a sodium lamp, and a product. Before a metal base material is stamped, a film is plated on the surface of the metal base material, and an oxide thin film is formed on the surface of the base material, so that the problems that the film is adhered to the metal material, a punch rod is broken easily, and a stamping part is not regular in the stamping process can be solved. By the method, the hard and plastic oxide thin film is formed on the surface of metal, so that the capacity of adsorbing stamping lubricant can be improved, the metal does not contact with a die, and adhesion is avoided; and therefore, the performance of a stamping process is greatly improved.

Description

technical field [0001] The invention relates to the field of processing guide tubes of arc tubes, in particular to a processing method and products for guide tubes of sodium lamp arc tubes. Background technique [0002] As the third-generation new electric light source, sodium lamp has the advantages of high luminous efficiency, low power consumption, long life, strong fog penetration ability and no insect trapping. It is widely used in roads, expressways, airports, docks, docks, stations, squares, Street intersections, industrial and mining enterprises, parks, garden lighting and plant cultivation. Because niobium and niobium-1% zirconium alloy materials have good sealing and welding properties, thermal shock resistance, good ductility and sodium ion corrosion resistance and other advantages between sodium lamp arc tube ceramics, its stamping parts are used in arc tubes. The guide tube, which plays the role of exhaust and conduction, is the key material for the manufacture...
