用冲头内聚积工艺,局部热镦粗摩托车前后轮轴大端。采用简易热镦模(图示)。该模具结构简单,制造容易,操作方便。上模由冲头2和上模板1组成,固定在100t油压机的滑块上。下模由镶块3、固定模座8、活动模座9及下模板10组成,安装在油压机的工作台上。镶块3分成两半,中心加工成φ14的(各半圆)孔,孔加工好后在轴线分开处各刨去0.5 Punch accumulation process, the local hot upset rough motorcycle front and rear axles. Using simple hot upsetting mold (pictured). The mold structure is simple, easy to manufacture, easy to operate. The upper die is composed of a punch 2 and an upper die plate 1, and is fixed on a slider of a 100t hydraulic machine. The lower die is composed of an insert block 3, a fixed die holder 8, a movable die holder 9 and a lower die plate 10, and is mounted on a hydraulic bench. Insert 3 is divided into two halves, the center processed into φ14 (each semicircle) hole, the hole is processed at the axis of each planer to 0.5
