Description
Technical Field
The utility model relates to a niobium pipe especially relates to a niobium pipe for sodium lamp.
Background
The niobium tube is a key part of sodium lamp products, and the niobium tube is connected with an electrode and is hermetically sealed with the ceramic tube. The production of the niobium tube of the sodium lamp is generally realized by riveting and pressing niobium particles step by a press, so that the material utilization rate of the niobium tube in the forming process is maximized. The existing niobium pipe is basically in a U-shaped or H-shaped structure, and the two niobium pipes have a common characteristic point, namely the specification of the whole pipe body is consistent. The niobium tube with the same specification has the common defect that the assembly position cannot be quickly and accurately obtained in the packaging process. Namely, the feeding amount of the niobium tube in the ceramic tube can not be determined, so that the assembly amount of the niobium tube of the sodium lamp can not be kept consistent, and the product quality of the whole sodium lamp is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the niobium tube can not be fast and accurately positioned in the process of packaging the ceramic tube.
In order to solve the technical problem, the step type niobium pipe of this scheme includes positive pole incoming end and niobium pipe body, the positive pole incoming end sets up at this end of body of niobium pipe, be provided with first cavity in the positive pole incoming end, this internal second cavity that is provided with of niobium pipe, niobium pipe body contains first order niobium pipe body and second order niobium pipe body, and this body coupling of second order niobium pipe is on first order niobium pipe body, and second order niobium pipe body diameter is greater than first order niobium pipe body diameter.
According to the further improvement of the technical scheme, the second-step niobium tube body is further connected with a third-step niobium tube body, and the diameter of the third-step niobium tube body is larger than that of the second-step niobium tube body.
According to the further improvement of the technical scheme, the diameter of the second-step niobium tube body is at least 0.4mm larger than that of the first-step niobium tube body, and the diameter of the third-step niobium tube body is at least 0.4mm larger than that of the second-step niobium tube body.
In a further improvement of the above technical solution, the first cavity is a cylindrical structure, and the second cavity is a stepped cylindrical structure.
In a further improvement of the above technical scheme, the outer side end of the first cavity and the outer side end of the second cavity are open structures.
According to the further improvement of the technical scheme, the length of the second niobium tube body is within 1 mm.
The step type niobium tube of this scheme can realize quick accurate location with ceramic pipe packaging in-process.
Drawings

Detailed Description
The bead type niobium tube structure will be described in detail with reference to the accompanying drawings.
The utility model provides a step type niobium pipe, includes anode incoming end 1 and niobium pipe body 2, anode incoming end 1 is in 2 side end of niobium pipe body, 2 opposite sides of niobium pipe body are open structure. A first cavity 11 is arranged in the anode access end 1, and the first cavity 11 is of a cylindrical structure. The other side of the anode access end 1 is an open structure. This internal second cavity 21 that is provided with of niobium pipe, second cavity 21 is step type cylinder structure, and step type cylinder structure is piled up according to the size by a plurality of different specification cylinders and forms, niobium pipe body 2 is connected gradually by first niobium pipe body 22, second niobium pipe body 23 and third niobium pipe body 24 and is constituteed, second niobium pipe body 23 diameter is greater than first niobium pipe body 22 diameter by 0.4mm, third niobium pipe body 24 diameter is greater than second niobium pipe body 23 diameter by 0.4 mm. The length of the second niobium pipe body 23 is 1 mm.
In the assembling process, the niobium pipe body 2 is inserted into the ceramic pipe, the end part of the ceramic pipe can be clamped by the second niobium pipe body 23 to complete quick and accurate positioning, and the third niobium pipe body 24 is used for quick and accurate positioning of the sealing ceramic cap to finally realize packaging.
