Description

Technical Field

[0001] The utility model relates to a polycrystalline painting die, belonging to the technical field of painting die equipment. Background Art

[0002] The painting by die method uses natural diamond painting dies, tungsten steel painting dies and ruby painting dies. Due to size limitations, natural diamonds can only be used to process small-sized painting dies (die size < 0.800 mm), while for large-sized painting dies (die size ≥ 0.800 mm), the core materials are tungsten steel and ruby. Tungsten steel and ruby have become the mainstream products of painting dies due to their simple processing, good surface roughness and high production efficiency.

[0003] However, due to poor wear resistance, when tungsten steel and ruby painting dies are used for a long time, there will inevitably be problems such as an increase in die size, grooves on the die hole surface, and large ovality. During the painting process of electromagnetic wires, there are prone to problems such as paint tumors, paint deviation, uneven paint layer, and unqualified paint film thickness. Now there is an urgent need for a polycrystalline painting die to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a polycrystalline painting die to solve the problems raised in the above background art. The utility model designs a wear-resistant polycrystalline die core painting structure, which is combined with a cleaning and lubricating auxiliary component, can achieve uniform painting of wire, and greatly improves wear resistance.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions: a polycrystalline painting die, including a graphite sleeve, a guiding inner sleeve, a polycrystalline die core and a painting part. The left end inside the graphite sleeve is fixedly installed with a guiding inner sleeve through a plurality of first reinforcing bolts. A cleaning cotton ring and a lubricating oil storage cotton ring are respectively installed on the left and right sides inside the guiding inner sleeve. The polycrystalline die core and the painting part are fixedly installed at the right end inside the graphite sleeve through a plurality of second reinforcing bolts. A paint storage groove is opened at the connection between the painting part and the inner wall of the graphite sleeve. A plurality of diversion holes are staggeredly arranged inside the painting part. A paint adding pipe is longitudinally installed on the right side of the upper end of the graphite sleeve. Sintered powder layers are arranged on the inner side walls of the polycrystalline die core and the painting part.

[0006] Furthermore, a tapered notch is opened at the edge of the left end inside the guiding inner sleeve.

[0007] Furthermore, lubricating oil is adsorbed in the lubricating oil storage cotton ring.

[0008] Furthermore, the left end of the painting part is in contact with the guiding inner sleeve.

[0009] Furthermore, all the plurality of diversion holes are communicated with the paint storage groove, and the lower end of the paint adding pipe is communicated with the paint storage groove.

Detailed Embodiment

[0017] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0018] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: A polycrystalline painting die includes a graphite sleeve 1, a guiding inner sleeve 2, a polycrystalline die core 8, and a painting part 7. The left end inside the graphite sleeve 1 is fixedly installed with the guiding inner sleeve 2 through a plurality of first reinforcing bolts 3. A cleaning cotton ring 5 and a lubricating oil storage cotton ring 6 are respectively installed on the left and right sides inside the guiding inner sleeve 2. The polycrystalline die core 8 and the painting part 7 are fixedly installed at the right end inside the graphite sleeve 1 through a plurality of second reinforcing bolts 12. A paint storage tank 9 is provided at the connection between the painting part 7 and the inner wall of the graphite sleeve 1. A plurality of diversion holes 10 are staggeredly arranged inside the painting part 7. A paint adding pipe 13 is longitudinally installed on the right side of the upper end of the graphite sleeve 1. Sintered powder layers 11 are provided on the inner side walls of both the polycrystalline die core 8 and the painting part 7.

[0019] As the first embodiment of the present utility model: a tapered notch 4 is provided at the left end edge inside the guiding inner sleeve 2. By adding the tapered notch 4, it is convenient for the loose wire to be inserted into the guiding inner sleeve 2.

[0020] The lubricating oil storage cotton ring 6 adsorbs lubricating oil. By adding the lubricating oil and the lubricating oil storage cotton ring 6, the wire that is bundled and extruded can be lubricated to prevent hard contact between it and the inner wall of the sintered powder layer 11 and prevent it from being easily worn. The left end of the painting part 7 is in contact with the guiding inner sleeve 2. A plurality of shunt holes 10 are all connected to the temporary paint tank 9 in communication. The lower end of the paint adding pipe 13 is connected to the temporary paint tank 9 in communication. By adding the temporary paint tank 9, it is convenient to store the paint liquid. And the setting of the paint adding pipe 13 is convenient for adding the paint liquid into the temporary paint tank 9. The staggered plurality of shunt holes 10 can uniformly perform the painting operation on the wire.

[0021] The polycrystalline die core 8 and the painting part 7 are integrally provided. By adding the sintered powder layer 11 arranged inside the polycrystalline die core 8, they are sintered together to form an artificial polycrystalline diamond sintered body, providing reinforcement for the blank. On the other hand, the prepared sintered body has a certain plasticity to protect the artificial polycrystalline diamond sintered body from being squeezed and deformed or cracked.

[0022] As the second embodiment of the present utility model: the added tapered notch 4 facilitates the insertion of the loose wire into the guiding inner sleeve 2. Then the wire passes through the wiping cotton ring 5 for wiping, and then contacts the lubricating oil storage cotton ring 6, which can lubricate the bundled wire to prevent hard contact between it and the inner wall of the sintered powder layer 11 and prevent it from being easily worn. The plurality of shunt holes 10 provided can uniformly perform the painting operation on the wire. Then the wire passes through the inside of the polycrystalline die core 8 for extrusion, which can improve the tightness of the paint liquid wrapped around the wire. The sintered powder layer 11 is arranged inside the polycrystalline die core 8, and they are sintered together to form an artificial polycrystalline diamond sintered body, providing reinforcement for the blank. On the other hand, the prepared sintered body has a certain plasticity to protect the artificial polycrystalline diamond sintered body from being squeezed and deformed or cracked, and has good wear resistance and is convenient for long-term use.
