在JBG_3偏心冲床上冲压汽车纸垫零件时,由于冲床滑块没有哈夫夹紧装置,通常用滑块上M20螺栓顶压模柄斜面的方法夹紧上模,对于用小模具、生产量少情况下,此种方法还可以采用,如果模具大些、生产最多了时,那就不行,常会发生螺丝顶压不紧、螺栓拉断等现象,即造成生产不安全、质量不可靠,影响了生产的正常进行,针对上述问题,我们进行了研究分析,经仔细观察,在冲床滑块工作台面有两个“T”形槽可利用。将采用下面两种方法来压固上模:
In the JBG_3 eccentric punch stamping automobile paper pad parts, because the punch slider does not have the Huff clamping device, the slider is usually M20 bolts on the top of the mold clamping mandrel oblique clamping method, with a small mold, less production Case, this method can also be used, if the mold larger, when the production up, it will not work, often occur tight pressure screws, bolt pull off and other phenomena, resulting in unsafe production, the quality of unreliable, affecting the Production of the normal, in view of the above problems, we conducted a study analysis, after careful observation, in the press slide table has two “T” shaped groove available. The following two methods will be used to press the upper die:
