申慱娱乐官方网站在温挤压前的处理
发布人:管理员   发布时间:2020-9-15

生产申慱娱乐官方网站时,在温挤压前除了要对坯料进行加热和润滑外,还要对挤压凸模和凹模进行预热。一般预热至150~300℃再进行挤压生产。申慱娱乐官方网站预热主要为了保证:
In the production of slope protection die, in addition to heating and lubricating the blank, the extrusion punch and die should be preheated before warm extrusion. Generally, it is preheated to 150-300 ℃ before extrusion. The preheating of slope protection mould is mainly to ensure that:

(1)使挤压坯料放入模具时坯料降温不致过快,以免塑性降低、变形抗力增加;同时避免坯料表面和中心层温差过大,以防止由于变形不均匀性而导致挤压件产生缺陷或申慱娱乐官方网站损坏。
(1) When the extruded blank is put into the mold, the temperature of the blank will not be too fast, so as to avoid the reduction of plasticity and the increase of deformation resistance; at the same time, the temperature difference between the surface of the blank and the central layer shall be avoided, so as to prevent the extrusion parts from producing defects or damage to the slope protection die due to the uneven deformation.

      

(2)减小申慱娱乐官方网站与毛坯接触的温差,避免模具表面的温度迅速上升而导致申慱娱乐官方网站内部温差过大而产生很大的内应力,以降低申慱娱乐官方网站在工作时产生破坏的危险。
(2) Reduce the temperature difference between the slope protection mold and the blank, avoid the rapid rise of the surface temperature of the mold, which leads to the large temperature difference inside the slope protection mold and produce great internal stress, so as to reduce the risk of damage of the slope protection mold in the work.
