中国农机化报曾刊登了“温室灌溉设备五道难题待解的报导,文章指出我国微灌设备现有30多家生产厂家,生产的主要产品有内镶式滴灌管、薄壁式孔口滴灌带、压力补偿式滴头、过滤器、施肥罐及各种规格的滴、微喷灌主支管等但大多处于试生产或小批量生产阶段,在技术上还存在五个方面的问题,其中包括生产工艺、材料、控制设备等。最近从国家教育部快速成型制造工程中心获悉,他们应用参数化设计思想进行了滴管CAD设计,然后以精密模具制造技术为核心,进行了滴管CAD工艺设计,RT工艺模型的生成,滴管金属喷涂快速注塑模具的设计和制造,实现了产品和模具设计-验证-制造集成化。该项技术集成了CAD技术、液固两相流技术、流体力学技术、光固化快速成型技术及快速精细模具制造技术,研制内容主要分为:节水农业微滴管(片)产品快速开发技术与该产品的精细模具制造技术。解决了嵌入式迷宫设计,结构复杂,模具的设计和制备的研制周期长,开发投入大的问题,并成功地制成滴管锌铝合金注塑模具(一模两腔),快速生产出了1000件滴管产品,用于农业节水灌溉试验,在此基础上还生产出了滴管注塑钢模(1模20腔),用于滴管的大批量生产。利用该技术开发的滴管(片)产品的产业化价格为1.2元/米,国产仿制低质量的同类产品价格为1.7元/米,以色列?
China Agricultural Mechanization News published "five issues of greenhouse irrigation equipment to be solved, the article pointed out that China’s micro-irrigation equipment more than 30 existing manufacturers, the main products are inlaid-type drip irrigation, thin-walled orifice drip irrigation Belt, pressure compensated dripper, filter, fertilizer tank and a variety of drops, micro-sprinkler main branch, but mostly in the trial production or small batch production stage, there are still five technical aspects of the problem, including production Technology, materials, control equipment, etc. Recently learned from the rapid prototyping and manufacturing engineering center of the Ministry of Education of China that they applied the design idea of parametric design to the design of the dropper CAD and made the design of the dropper CAD process taking the precision mold manufacturing technology as the core, RT process model generation, design and manufacture of rapid injection molds for dropper metal spraying, and integration of product and tooling design - verification - manufacturing integration of CAD technology, liquid-solid two-phase flow technology, fluid mechanics, Light curing rapid prototyping technology and rapid die manufacturing technology, research content is divided into: water-saving agricultural droplet (film) product rapid development technology and the product It has solved the problems of the design of embedded labyrinth, complex structure, long development cycle of mold design and preparation, large investment in development, and the successful manufacture of dropper zinc-aluminum alloy injection mold (one mold and two cavities) Rapid production of 1000 dropper products for agricultural water-saving irrigation test, on the basis of this also produced a dropper injection mold (1 mode 20 cavity) for the dropper of the high-volume production using the technology Development of the dropper (film) product price of 1.2 yuan / m, domestic imitation of low-quality products of the same price of 1.7 yuan / m, Israel?
