塑料推拉窗三、四等分扇宽度的几种下料计算方法分析（Analysis of several methods of cutting off the width of three or four equal parts of plastic sliding window） Analysis of several methods of cutting off the width of three or four equal parts of plastic sliding window Shenzhen Shun Jia hi tech building materials Co., Ltd. Yang Zhongjiu Plastic sliding window three or four equal parts, fan width blanking total of the following calculation methods: are discussed separately, comment follows: First, plastic door and window, three equal parts, fan width of several materials calculation method 1, with frame size as the benchmark, three equal frame blanking calculation method: Side fan width = window width /3 - frame width + lap volume + (fan width + capping thickness) /2 - capping thickness + 6 Medium fan width = window width /3 + fan width - capping thickness + 6 See Figure 1 for specific segmentation: Comment: the sliding window material calculation method of production, in the closed state, three were not very fan width, the middle fan is too wide; compared with the other two methods, in the side open, open the largest area in the middle of open, open area and the lowest in the sliding window width limit the case, for the side open with. The disadvantage is that the same window needs to be made with two different widths of fans, which makes it more difficult to process; 2, within the frame size as the benchmark, three equal frame blanking calculation method: Side fan width = (window width * 2 * frame width), /3 lap number (fan width, capping thickness) /2 - capping thickness 6 Medium fan width = window width 2 x frame width) /3 + fan width - capping thickness 6 See Figure 2 for specific segmentation: Comments: the above calculation method produced by sliding window, in the closed state, the three fans of the same width, it seems to be relatively called. Compared with the other two methods, the opening area is moderate, whether it is side opening or middle opening. The two opening methods are mor
