缺口耙片的制造工艺一般是:冲方孔—落料—车外圆刃口—冲缺口—铣缺口的刃口—成型—热处理—涂漆包装。缺口部分的刃口和外圆刃口的角度是一致的,比较锋利,碎土、入土性能较好,但由于工艺落后,耙片制造费用较高。我厂吸收国外技术,对缺口耙片的缺口部分进行了研究,并根据我厂的设备条件,将缺口耙片的生产工艺改为:落料成型—冲方孔—冲缺口—车外圆刃口—热处理—涂漆包装。缺口和它的刃口一次冲压而 Gap cutter blade manufacturing process is generally: Chong Fang hole - blanking - the car outside the round edge - notched notch - the edge of the milling gap - forming - heat treatment - paint packaging. Notched part of the edge and the outer edge of the blade angle is the same, more sharp, broken soil, into the soil better performance, but due to backward technology, blade manufacturing costs higher. I plant to absorb foreign technology, the gap of the harrow piece of the gap were studied, and in accordance with the conditions of our plant equipment, the production process of the notch harrow to: blanking forming - red square hole - red notch - car round edge - heat treatment - paint packaging. Notch and its cutting edge stamping time
