Description

Precise chromium-zirconium-copper microporous tube

Technical Field

The utility model belongs to the technical field of the micropore pipe, concretely relates to accurate chromium zirconium copper micropore pipe.

Background

The Cr-Zr-Cu microporous tube for electric nozzle is used to manufacture electric nozzle, electrode connecting rod, etc. for gas shielded welding. The aperture of the chromium-zirconium-copper micropore is required to be precise and smooth, and the requirement of good directivity of the welding wire can be ensured.

When the current chromium zirconium copper contact nozzle is produced, drill bits at two ends of a chromium zirconium copper bar are only adopted for drilling, then wire is threaded, then forging and shrinkage are performed, finally a wire drawing process is used for production, the process flow is only equivalent to extruding the inner hole of a chromium zirconium copper microporous tube once, although the process flow can be used reluctantly, the strength is far from insufficient, the main reason is that the hardness of the cross section of the bar is gradually reduced from the outside to the center, the hardness of the center part is the lowest, and the hole of the contact nozzle is located at the center part, so that the contact nozzle uses the part with the weakest performance of the bar, and the service life of the contact nozzle is not enough; in the drilling process of the drill bit, deviation is easy to occur, the drilling is inaccurate, the drilling fails, and pipes are wasted.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an accurate chromium zirconium copper micropore pipe strengthens central part hardness, improves the current contact nozzle life-span, and makes things convenient for the drilling to use.

The utility model provides an accurate chromium zirconium copper micropore pipe, includes the body and establishes drilling tool on the body, the body is equipped with central micropore, enclose in the body central micropore is equipped with the bush, the bush stretches out be equipped with the bush turn-ups on the outside direction of body department, surround in the body the bush is equipped with the strengthening rib, on the body terminal surface with central micropore symmetry both sides are equipped with the locating hole respectively, be equipped with the locating lever on the drilling tool both sides, the locating lever with the locating hole is pegged graft and is matchd, drilling tool corresponds central micropore position is equipped with drilling, drilling bilateral symmetry is equipped with the bearing.

Preferably, a protective layer is arranged in the pipe body and surrounds the reinforcing ribs.

Preferably, the material of the protective layer is silicon carbide.

Preferably, the number of the bearings is at least 4, and the bearings are symmetrically arranged with the drill hole as the center.

Preferably, a cavity is formed between the drilling jig below the drilled hole and the pipe body surface, and the bushing flanging is arranged in the cavity.

The utility model has the advantages that: the strength of the central micro-hole is enhanced through the pipe body by the reinforcing structure, so that the overall strength of the pipe body in the use process is improved, and the service life of the pipe body is prolonged; the matched drilling jig is additionally arranged on the pipe body, so that the pipe body can be conveniently and accurately drilled, and the waste of the pipe is avoided.
