Problems solved by technology

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a high-speed large round wire horizontal enamelling machine enamelled diamond mold: by setting the diamond core, the diamond core has the characteristics of good stability, not easy to run out, and long service life. , the diamond mold core body is connected with the mold base through the sintered body. The sintered body has a high tensile strength, so that the diamond and the mold sleeve are welded into a whole, which solves the problem that the existing high-speed horizontal machine paint mold will cause the mold to be stuck. wire, resulting in poor enameled wire quality, many defective products, large amount of waste wire, and poor parallelism of the paint film.

Embodiment 1

[0038] Present embodiment is a kind of grinding aid, and the preparation process of this grinding aid is as follows:

[0039] A1: Add sulfuric acid solution and anisole to a three-necked flask equipped with a thermometer, a reflux condenser, a constant pressure dropping funnel, and a magnetic stirrer, and then stir the reaction at room temperature and at a stirring rate of 100r / min After 30 minutes, cool down in an ice-water bath to below 15°C, add sodium nitrite solution drop by drop while stirring, control the dropping rate at 1 drop / s, continue stirring for 5 minutes after the addition is complete, then add urea, and then collect the reaction solution , add deionized water in the four-necked flask that thermometer, constant pressure dropping funnel and mechanical stirrer are installed, add concentrated sulfuric acid and anhydrous copper sulfate while stirring under the condition that stirring speed is 300r / min, then be warming up to 110 ℃, control the heating rate to 3 ℃ / mi...

Embodiment 2

[0045] Present embodiment is a kind of grinding aid, and the preparation process of this grinding aid is as follows:

[0046] A1: Add sulfuric acid solution and anisole to a three-necked flask equipped with a thermometer, a reflux condenser, a constant pressure dropping funnel, and a magnetic stirrer, and then stir the reaction at room temperature and at a stirring rate of 300r / min After 40 minutes, cool down in an ice-water bath to below 15°C, add sodium nitrite solution drop by drop while stirring, control the dropping rate at 1 drop / s, continue to stir and react for 15 minutes after the dropwise addition, then add urea, and then collect the reaction solution , add deionized water in the four-necked flask that thermometer, constant pressure dropping funnel and mechanical stirrer are installed, add concentrated sulfuric acid and anhydrous copper sulfate while stirring under the condition that stirring rate is 500r / min, then be warming up to 110 ℃, control the heating rate to ...

Embodiment 3

[0052]This embodiment is an enamelled diamond mold for a high-speed large round wire horizontal enamelling machine, which is prepared by the following steps:

[0053] Step 1: Perforate the diamond with laser, ultrasonically shape and polish it to the required hole shape and size to obtain the mold core;

[0054] Step 2: Add nickel, zinc, cobalt, molybdenum, copper, tungsten, and tin into a high-speed mixer, and mix and stir for 3 hours at a stirring rate of 500r / min to obtain a mixed raw material, which is mixed with the mixed raw material from the example The grinding aid in 1 is added to the ball mill for ball milling to obtain sintered powder;

[0055] Step 3: Fix the mold base with a graphite mold sleeve, place the mold core in the mold base, then add sintering powder between the mold base and the mold core, and then put it on a hot-press sintering machine for sintering processing, first at a temperature of 500°C , preheated at a pressure of 0.5MPa for 60s, then sintered ...

Abstract

The invention discloses an enamelled diamond mold of a high-speed large round wire horizontal enameling machine, and relates to the field of high-speed large round wire horizontal enamelling machine painting processes. Diamond is processed to form a mold core, nickel, zinc, cobalt, molybdenum, copper, tungsten and tin are mixed and stirred to obtain a mixed raw material, the mixed raw material and a grinding aid are added into a ball mill for ball milling to obtain sintered powder, a mold holder is fixed by a graphite mold sleeve, the mold core is placed in the mold holder, then the sintered powder is added between the mold holder and the mold core for sintering processing, the mold core is fixed to the center of the mold holder through hot pressing sintering by a powder metallurgy process, and the mold is obtained. According to the mold, the diamond mold core is arranged, the diamond mold core has the advantages of being good in stability, not prone to number shifting, long in service life and the like, a diamond mold core body is connected with the mold holder through a sintering body, the sintering body has high tensile strength, the diamond and the mold sleeve are welded into a whole, the situation that the mold core is stable can be effectively ensured, and gap paint leakage is permanently rejected.

Description

technical field [0001] The invention relates to the field of painting technology of a high-speed large-size round wire horizontal enamelling machine, in particular to an enamelled diamond mold for a high-speed large round wire horizontal enamelling machine. Background technique [0002] The enamelled wire painting process involves high-speed horizontal machine painting molds. At present, the horizontal large round wire enamelling machine imported from abroad is equipped with alloy mold cores, which have the disadvantages of poor finish and unstable tolerance, and the seam is easy after exposure to high temperature. Paint leakage will lead to mold scrapping. During the production process, the mold is easy to be large, and the large size is difficult to find. For example, if the front line is large and the back line is small, it will cause the die to be stuck and broken, resulting in poor quality enameled wire, many defective products, and a large amount of wire waste. The par...
