我们生产的 T 形齿轮(图1),由于采用了一次模锻法,生产效率比原先提高1倍多。原先采用的方法是这样的:首先把下好的料加热到锻造温度。开始锻造和材料的大小很有关系:如果材料直径小于锻模小口径,可以把材料直接放下去镦锻(图2甲);如果材料直径大于锻模小口径,必须把相当于小口径高的一段材料甩细后再放下去锻(图2乙)。镦锻的设备是2/5吨汽锤。当锻到锻坯充满锻模小口径的时候,如果再往下锻,锻
Our T-shaped gear (Figure 1), due to the use of a die forging method, the production efficiency more than doubled. The original method used is this: First, the next good material is heated to forging temperature. Starting forging and the size of the material is very relevant: If the diameter of the material is smaller than the die diameter, you can put the material down directly upsetting (Figure 2 A); if the material diameter is larger than the die diameter, you must be equivalent to the small diameter A fine material after rejection down forging (Figure 2 B). Upsetting equipment is 2/5 tons of hammer. When the forging billet is full of forging small diameter, if further down forging, forging
