在ΟΠ-3型横向蒙皮拉伸机上,增设“上压装置”附件(见17页图1所示),可以对双曲度带局部急剧变化的凹陷、凸包和梗条大蒙皮(如图2所示)进行拉伸、顶压一次成形。从而减轻了人工用硬橡皮条抽打、木榔头槌击的笨重体力劳动,提高了生产效率,确保了产品质量,并扩大了机床的使用范围。经过两年多的生产实践,效果良好。
In the ΠΠ-3 horizontal skin stretching machine, the addition of “pressure device” attachment (see Figure 1 on page 17), can be double-curvature with local rapid changes in the sag, convex hull and big skin ( Shown in Figure 2) to stretch, a pressure forming. Thereby reducing the manual hard rubber stripping, hammering wooden hammer heavy physical labor, improve production efficiency, ensure product quality, and expanded the use of machine tools. After more than two years of production practice, the effect is good.
