Embodiment 1

[0018] Example 1: Set the atmospheric atmosphere resistance heating furnace to 400°C and then send power to increase the temperature; the heating furnace temperature reaches the set temperature and keep holding for 30 minutes; open the furnace door and place the niobium wire in the central area of ​​the furnace; close the furnace Door, after the temperature in the furnace returns to the set temperature, keep it for about 12 minutes; the heating furnace is powered off; the furnace door is opened, the wire is out of the furnace; pressing is performed.

Embodiment 2

[0019] Example 2: Set the atmospheric atmosphere resistance heating furnace to 420°C and then send power to increase the temperature; the heating furnace temperature reaches the set temperature and keep holding for 30 minutes; open the furnace door and place the niobium-1% zirconium alloy wire in the furnace Central area; close the furnace door and keep the temperature in the furnace for about 8 minutes after the temperature is restored to the set temperature; the heating furnace is powered off; the furnace door is opened and the wire is discharged; punching is performed.

[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 direct stamping of bare metal bars, which greatly improves the difficulty of stamping and demoulding and the surface of stamping parts. The problem of easy strain 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 processing field of a guide tube of an arc tube, in particular to a method and product for processing a guide tube of a sodium lamp arc tube. Background technique [0002] As a third-generation new electric light source, sodium lamp has the advantages of high luminous efficiency, low power consumption, long life, strong fog penetration and no insect trapping. It is widely used in roads, highways, airports, docks, docks, stations, squares, Street intersections, industrial and mining enterprises, parks, courtyard lighting and plant cultivation. Because niobium and niobium-1% zirconium alloy materials and sodium lamp arc tube ceramics have the advantages of good sealing, thermal shock resistance, good ductility and sodium ion corrosion resistance, the stamping parts are used in the arc tube. The guide tube, which plays the role of exhaust and conduction, is the key material for the manufacture of high-pressure nano-lamp arc light-...
