Description

一种点胶用喷嘴及其制造方法Nozzle for dispensing glue and manufacturing method thereof 技术领域technical field
本发明涉及点胶领域，特别是一种点胶用喷嘴及其制造方法。The invention relates to the field of glue dispensing, in particular to a nozzle for glue dispensing and a manufacturing method thereof.
背景技术Background technique
点胶机，需要有精密点胶配件的支持才能够完成生产需求，其中最为核心的配件就是点胶阀，而点胶阀中最为核心的配件就是撞针和点胶嘴。点胶的操作是通过电磁阀控制撞针和点胶嘴高频率开合，实现胶水的通过和关闭。因此，撞针和点胶嘴的寿命至关重要。The dispensing machine needs the support of precision dispensing accessories to meet the production requirements. The most core accessories are the dispensing valve, and the most core accessories of the dispensing valve are the needle and the dispensing nozzle. The operation of dispensing is to control the high-frequency opening and closing of the striker and the dispensing nozzle through the solenoid valve to realize the passage and closure of glue. Therefore, the life of the needle and nozzle is critical.
现有的点胶嘴会采用高硬度高耐磨的材料，如不锈钢和钨钢。普通合金钢的硬度较低HRC60~65，耐磨性差，钨钢的硬度较高 HRC80以上，故而点胶嘴会采用钨钢制成。然而钨钢中含有钴，如常用的钨钢牌号日本住友 AF1,其钴含量为12%，在点胶的过程中，胶液中的部分化学成分会造在钨钢中的钴流失。钴在钨钢中的作用是粘结剂，WC（碳化钨）是非常坚硬、非常耐磨、难熔的物质，其熔点可达到(2870±50)℃；而钴的熔点是1430℃左右；当硬质合金毛坯在烧结过程中，当温度升高到1430℃左右时，钴已达到熔点，是熔融状态，渗透到WC（碳化钨）的缝隙中，使WC和Co进行紧密结合，当温度冷却后，就成了硬质合金；故而，硬质合金真正起到耐磨耐压作用的是WC，钴起到的是粘结作用；当钨钢表面发生钴流失后，就会失去弹性和韧性，从而很快脆化失效。因此，现有采用钨钢制成的点胶嘴在反复的撞击点胶过程中，点胶嘴会很快催化失效，寿命较短，需要频繁更换零部件。Existing dispensing nozzles will use high hardness and high wear resistance materials, such as stainless steel and tungsten steel. The hardness of ordinary alloy steel is lower than HRC60~65, and the wear resistance is poor. The hardness of tungsten steel is higher than HRC80, so the dispensing nozzle will be made of tungsten steel. However, tungsten steel contains cobalt. For example, the commonly used tungsten steel brand Sumitomo AF1 has a cobalt content of 12%. During the dispensing process, some chemical components in the glue will cause cobalt loss in the tungsten steel. The role of cobalt in tungsten steel is a binder. WC (tungsten carbide) is a very hard, very wear-resistant, and refractory substance. Its melting point can reach (2870±50)°C; while the melting point of cobalt is about 1430°C; When the cemented carbide blank is in the sintering process, when the temperature rises to about 1430 ° C, the cobalt has reached the melting point and is in a molten state, and penetrates into the gap of WC (tungsten carbide), so that WC and Co are closely combined. When the temperature After cooling, it becomes cemented carbide; therefore, it is WC that really plays the role of wear resistance and pressure resistance in cemented carbide, and cobalt plays the role of bonding; when cobalt is lost on the surface of tungsten steel, it will lose its elasticity and Toughness, which quickly becomes embrittled and fails. Therefore, the existing dispensing nozzles made of tungsten steel will quickly catalyze failure during the repeated impact dispensing process, the life of the dispensing nozzles is short, and parts need to be replaced frequently.

The nozzle body made of polycrystalline diamond is installed in the nozzle seat, and it is difficult to directly chemically react with the workpiece material, and the problem of cobalt loss will not occur, which can effectively reduce The downtime and adjustment time caused by frequent replacement of parts can ensure the stability of processing quality.
