Problems solved by technology

However, for the core with a through hole in the axial direction, the outer diameter is Ф8.5mm±0.025mm, the inner diameter of the through hole is Ф2.5mm±0.025mm, the length is 500mm±1mm, the coaxiality <0.25mm, and the straightness <0.25mm / 305mm Silver-based alloy rods have a relatively large length and diameter and thick wall thickness. The processing of rolled pipes has the following disadvantages: 1. Low rolling efficiency; 2. Due to the high coaxiality requirements of this product, the same The axiality is not easy to guarantee under the traditional rolling method, and the yield is extremely low; 3. Since this product is a silver-based alloy bar, it is easy to form defects such as scratches and pits by rolling

Embodiment 1

[0024] like figure 1 and figure 2 As shown, the silver-based alloy rod processing jig of this embodiment includes a first half-pipe clamp 1 and a second half-pipe clamp 2 matched with the first half-pipe clamp 1, and is used to fasten the first half-pipe The clamp 1 and the pipe collar 3 of the second half-pipe clamp 2 , the silver-based alloy rod to be processed is clamped between the first half-pipe clamp 1 and the second half-pipe clamp 2 .

[0025] In this embodiment, both ends of the silver-based alloy rod to be processed pass through the clamp.

[0026] In this embodiment, the materials of the first half-pipe clamp 1 and the second half-pipe clamp 2 are industrially pure titanium (TA1).

[0027] In this embodiment, there are multiple pipe collars 3, and the multiple pipe collars 3 are evenly sleeved on the fixture. The number of pipe clamps 3 is generally 3, 4, 5 or 6, etc., and the distance between two adjacent pipe clamps is about 80 mm to 160 mm.

Embodiment 2

[0029] Adopt the method for clamp processing silver-based alloy bar described in embodiment 1, may further comprise the steps:

[0030] Step 1. The diameter of the silver-based alloy rod to be processed is 8.5mm±0.025mm, and the length is 500mm±1mm. According to the diameter and length of the silver-based alloy rod to be processed, select the corresponding size fixture, and the silver-based alloy rod to be processed The material is fixed between the first half-pipe fixture 1 and the second half-pipe fixture 2, so that the outer wall of the silver-based alloy bar to be processed is close to the inner surface of the fixture, and the first half-pipe fixture 1 and the second half-pipe fixture 1 are fastened with the pipe clamp 3 Two half-pipe clamps 2 to obtain the assembly to be processed;

[0031] Step 2, using a deep hole drilling machine to carry out drilling processing to the assembly to be processed described in step 1, the spindle speed of drilling processing is 6000 revolu...

Embodiment 3

[0034] Adopt the method for clamp processing silver-based alloy bar described in embodiment 1, may further comprise the steps:

[0035] Step 1. The diameter of the silver-based alloy rod to be processed is 8.5mm±0.025mm, and the length is 500mm±1mm. According to the diameter and length of the silver-based alloy rod to be processed, select the corresponding size fixture, and the silver-based alloy rod to be processed The material is fixed between the first half-pipe fixture 1 and the second half-pipe fixture 2, so that the outer wall of the silver-based alloy bar to be processed is close to the inner surface of the fixture, and the first half-pipe fixture 1 and the second half-pipe fixture 1 are fastened with the pipe clamp 3 Two half-pipe clamps 2 to obtain the assembly to be processed;

[0036] Step 2, using a deep hole drilling machine to carry out drilling processing to the assembly to be processed described in step 1, the spindle speed of drilling processing is 5000 revolu...

Abstract

The invention discloses a jig for processing silver-based alloy rods. The jig includes a first half-pipe jig and a second half-pipe jig matched with the first half-pipe jig, and is used for fastening the first half-pipe jig. and the pipe collar of the second half-pipe clamp, the silver-based alloy rod to be processed is clamped between the first half-pipe clamp and the second half-pipe clamp. In addition, the invention also discloses a method for processing silver-based alloy rods by using the jig. The present invention adopts self-designed clamps to fix silver-based alloy rods, which can keep the silver-based alloy rods stable under high-speed rotation, reduce jumping, and ensure that the cutter head can stably feed in the axial direction when processing through holes. Secondly, avoid It prevents the bending and deformation of silver-based alloy rods under high-speed rotation, and at the same time avoids the risk of surface bumps, scratches, and pits on the surface due to the low hardness of silver-based alloy rods during processing, so that the silver-based alloy rods after processing The straightness of the material remains at the level before processing.

Description

technical field [0001] The invention belongs to the technical field of alloy processing, and in particular relates to a jig for processing silver-based alloy rods and a processing method. Background technique [0002] Traditional tubing is made using a drawing process. However, for the core with a through hole in the axial direction, the outer diameter is Ф8.5mm±0.025mm, the inner diameter of the through hole is Ф2.5mm±0.025mm, the length is 500mm±1mm, the coaxiality <0.25mm, and the straightness <0.25mm / 305mm Silver-based alloy rods have a relatively large length and diameter and thick wall thickness. The processing of rolled pipes has the following disadvantages: 1. Low rolling efficiency; 2. Due to the high coaxiality requirements of this product, the same The axiality is not easy to guarantee under the traditional rolling method, and the yield is extremely low; 3. Since this product is a silver-based alloy bar, it is easy to form defects such as scratches and pits...
