我单位制作了一种专用钉玻璃刀。上玻璃时一只手就可以操作,而且又快又好。钉玻璃刀是用费钢锉制成,成型后充上磁。上玻璃时,应将玻璃钉吸在刀口上,轻轻往扇侧一磕,就能将钉钉上,钉玻璃刀的形状见图1。钉玻璃刀充磁方法很简单。将直流电焊机焊把盘线成圆圈。直径大于成型钉玻璃刀约10厘米。将刀具南北方向放置,见图2。绕20圈以上即可。开启电焊机,电
My unit produced a special nail glass knife. A glass can be operated with one hand and it is fast and good. Spiked glass knives are made of Feisteel enamel and are filled with magnets after molding. When the glass is on, the glass nails should be sucked on the knife edge, and the nails can be screwed on the side of the fan. The shape of the nail glass cutter is shown in Figure 1. The nail glass knife magnetization method is very simple. The DC welder welds the disk coils into a circle. The diameter is greater than about 10 cm for forming nail glass cutters. Place the tool in a north-south direction, see Figure 2. Wind more than 20 turns. Turn on the welding machine, electricity
