一、前言平锻机是曲柄压力机的一种。它主要采用局部镦粗的方法生产模锻件。在平锻机上能实现局部镦粗聚积、冲孔、翻边、切边、弯曲、切断等工序。由于它的生产率比较高,因此,在汽车、拖拉机、航空和轴承行业的大批量生产中得到广泛应用。平锻机按被夹紧凹模的分开方向分为垂直分模和水平分模两种。水平分模平锻机的传动环节较垂直分模少,机身结构简单重量轻,且容易实现机械化操作。我厂自西德 HASENCLEVER 公司引进的 WSHK 1250水平分模平锻机,主滑块镦锻力1250t。该机夹紧凹模夹紧力是主滑块镦锻力的1.25倍,达1600t。下凹模中带有顶出装置。
First, the foreword forging machine is a crank press. It mainly uses the method of local upset forging forgings. In the forging machine can achieve local upsetting accumulation, punching, flanging, trimming, bending, cutting and other processes. Due to its high productivity, it is widely used in high volume production in the automotive, tractor, aerospace and bearing industries. Flat forging machine is divided according to the direction of separation of the die is divided into vertical parting and horizontal parting two. Horizontal split-level forging machine transmission part of the vertical split less than the model, the fuselage structure is simple and lightweight, and easy to mechanized operation. I plant from West Germany HASENCLEVER company introduced the level of WSHK 1250 level forging machine, the main slider upsetting force 1250t. Clamping machine die clamping force is the main slider upsetting 1.25 times, up to 1600t. Under the die with the ejection device.
