我们在使用原电镦机时,常常出现坯料电镦完后,夹紧缺不能及时泄荷松开。有时要让镦粗缸复位到止点时,夹紧缺才猛然松开。这时有些坯料温度已下降到终锻温度以下,对下道工序的模压成形很不利。因此,常常使电镦件大头前端出现叠层和裂纹,应力组织很不理想。改造后的电镦机在通往砧子缸和镦粗缸的油路中分别加了减压阀和压力继电器(含时间继电器)从而使电 When we use the original electric upsetting machine, often appear blank upsetting electricity, the lack of timely release of the clamp release. Sometimes to reset the upsetting cylinder deadline, the lack of a sudden release of the clamp. At this time some billet temperature has dropped to below the final forging temperature, the downstream process is very negative. Therefore, often make the upsetting bulkhead front stack and cracks, stress organization is not ideal. After the transformation of the electrical upsetting machine to the anvil cylinder and upsetting cylinder were added pressure relief valve and pressure relay (including time relay) so that the electricity
