Problems solved by technology

However, this kind of medical capillary tube is a very fine product, with a small size, a diameter of less than 1 mm, a wall thickness of less than 0.1 mm, and a weight of only 3.5 mg for each tube. The smoothness and the verticality between the two ports of the pipe fittings and the pipe string are very demanding. It is difficult to produce by conventional methods, and the yield is only about 10%.

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] Such as Figure 1-6 As shown, the grinding tube assembly of the present invention includes a clamp ring 5 and a short tube assembly 6, wherein the short tube assembly is a strip-shaped titanium capillary tube cut into a φ0.8×0.05mm titanium capillary tube with a length of about 140mm-150mm, and every 1000 A titanium capillary 9 is packed into a strip-shaped bundle, and a φ10mm×250mm iron mandrel 1 is clamped in the center of the strip-shaped bundle. One end of the iron mandrel is aligned with one end of the bar-shaped titanium capillary, and the other end of the iron mandrel extends out of the The outside of the bundle; the outside of the strip bundle is bound tightly with wrapping paper 2, adhesive tape 3 and rubber strip 4 in sequence; the strip bundle is cut into short tube assemblies with a length of 7 mm.

[0041] Cut the φ25×2mm steel pipe or ti...

Abstract

The invention provides a processing method for a high-precision Ti capillary pipe fitting and a pipe grinding assembly used in the processing method. The precise Ti capillary pipe fitting is produced by the steps of adopting a laser diameter measuring instrument and an eddy current flaw detector for optimally selecting pipe blanks, adopting a specific process to draw Ti capillary pipes, adopting ultrasonic waves to clean the capillary pipes, blanking the bundled capillary pipes by adopting a specific fastening clamp, and preparing the pipe grinding assembly, and finely grinding the end faces of the capillary pipes on a grinding machine. The method has the technological characteristics of good product quality, high finished rate, higher production efficiency, less equipment investment and suitability for production in batch.

Description

technical field [0001] The invention relates to the field of metal material processing, in particular to a processing method of a titanium capillary piece and a grinding tube assembly used in the method. Background technique [0002] Titanium metal has the advantages of light weight, corrosion resistance, non-toxicity, and good biocompatibility with the human body. As a new type of medical material, titanium has been widely used as a device for human interventional surgery. For example, titanium capillary tubes are used as radioactive seed capsules for the treatment of malignant tumors, storing radioactive iodine. The radiation penetrates the titanium capillary wall and acts on the tumor cells to obtain a good therapeutic effect. However, this kind of medical capillary tube is a very fine product, with a small size, a diameter of less than 1 mm, a wall thickness of less than 0.1 mm, and a weight of only 3.5 mg for each tube. The smoothness and the perpendicularity between ...
