过去我厂对于较大的拉延零件都要设计成套的拉延模具。这种模具设计、制造周期长,用料多;有左右件的零件,又需要两套模具。使用保管都不方便。 为了解决这个问题,我们设计了两块通用拉延模板,外廓尺寸2000×1000毫米,厚50毫米,用在250吨冲床上。通过一段时间的使用证明,该模具虽然有一定优点,但也存在一些缺点和不足。由于上下模板是用50毫米钢板制成的,中间又有间距50毫米、直径
In the past I plant for the larger drawing parts have to design complete sets of drawing die. This mold design, long manufacturing cycle, materials and more; have left and right parts, but also two sets of mold. Use of custody is not convenient. To solve this problem, we designed two universal drawing templates with dimensions of 2000 × 1000 mm and a thickness of 50 mm for use on a 250-ton punch press. Through the use of a period of time to prove that although the mold has some advantages, but there are also some shortcomings and deficiencies. As the upper and lower template is made of 50 mm steel, the middle of another 50 mm spacing, diameter
