由于机械传动牛头刨床主运动的速度参数是用滑枕频率(每分钟往复次数)来表示的,在同一档频率下,滑枕行程不同时切削速度也不同,其关系为: v=0.0017L·n 式中:v——平均切削速度,m/min:L——滑枕工作行程,mm;n——滑枕工作频率,min~(-1) 若要根据预定的v与L来选择n,则要进行计算或凭经验选取,这给操作带来不便。这里介绍一种速度图,使用方便,供读者参考。本文附图是根据B6050型牛刨绘制而成,下面举例说明其用法。设工件长度为l=200mm,要求使用v=20m/min。由图中可知,下列三种情况均能满足要求:n=51,
Since the speed of the main motion of the mechanical transmission shaper is expressed by the ram frequency (reciprocation per minute), the cutting speed is different at different ram travels at the same frequency, the relationship is: v = 0.0017L · n where: v - average cutting speed, m / min: L - ram working stroke, mm; n - ram working frequency, min ~ (-1) , You have to calculate or empirically choose, which inconveniences the operation. Here to introduce a speed map, easy to use, for readers reference. The drawings in this article are based on the B6050 cattle planing drawn, the following examples illustrate its usage. Set the length of the workpiece l = 200mm, requires the use of v = 20m / min. As can be seen from the figure, the following three conditions can meet the requirements: n = 51,
