在制造锻模时,必须考虑锻压成型后锻件如何容易地从锻模里取出来。通常应使锻模小头有一定的斜度(一般为7°)。因此制造锻模时要使用锻模样板来检验,而加工锻模样板过程中,如果使用专用的卡尺来测量,将使测量工作简化。专用卡尺可用一般卡尺改制,只要把卡尺量爪磨出一个7°的斜度(如图所示)就可以了。 When making a forging die, one must consider how the forging can easily be removed from the forging die after the forging process. Generally, the head of a forging die should have a slight slope (usually 7 °). Therefore, the use of forging die forging model to test, and the process of forging model, if the use of a dedicated caliper to measure, will simplify the measurement. Special calipers can be restructured with a general caliper, as long as the caliper grinding a 7 ° tilt (as shown) on it.
