我厂在加工压铸模及橡胶模具时,偶然会遇到大导程L=600～3000mm的内螺旋型腔,见图1。经过长时间的实践和摸索,总结出如下的加工方法。 1.在X62W万能铣床上,从铣螺旋槽交换齿轮表中查出交换齿轮的齿数为z_1=80,z_2=70、z_3=35,z_4,=100 2.按图3所示安装好分度头及万能立铣头。粗加工时,把φ10立铣刀装在主轴孔中的钻夹头内,并将立铣头主轴转过螺旋角β,按工件端面已划线的槽形为准,机动进刀,粗加工螺旋槽成形(见图2)。精加工时,把精加工刀具(按图1螺旋槽的截面,将刀头磨成如图3 A-A放大所示形状,同时要准备一支长度大于工作高度的刀杆)装在主轴内,然后按图要求,
I plant processing die-casting molds and rubber molds, by chance, will encounter a large lead L = 600 ~ 3000mm inner spiral cavity, see Figure 1. After a long period of practice and exploration, summed up the following processing methods. 1. In the X62W universal milling machine, from the milling spiral groove exchange gear table found in the exchange gear teeth z_1 = 80, z_2 = 70, z_3 = 35, z_4, = 100 2. As shown in Figure 3 installed indexing Head and universal legislation milling head. Roughing, the φ10 cutter installed in the spindle hole in the drill chuck, and the milling head spindle rotation angle β, according to the workpiece has crossed the slot-shaped subject, motorized feed, roughing Spiral groove forming (see Figure 2). Finishing, the finishing tool (Figure 1 spiral groove cross section, the blade ground into the shape shown in Figure 3 AA enlargement, while preparing a length greater than the working height of the arbor) installed in the spindle, and then According to map requirements,
