forging-圣霖国际【顾客至上】-forging生产厂家

锻造设备种类很多，按照工作部分运行方式不同，forging采购，锻造设备可分为直线往复运动和相对旋转运动两大类。直线往复锻造设备1、动载撞击的锻造设备2、动静载联合的锻造设备3，高效能冲击的锻造设备。

There are many kinds of forging equipment. According to the different operation modes of the working part， the forging equipment can be divided into two categories: straight reciprocating motion and relative rotation motion.

Linear reciprocating forging equipment

1， forging equipment with dynamic load impact

2，forging生产厂家， forging equipment combined with static and static load

3， high efficiency impacting forging equipment

自由锻都是以生产批量不大的锻件为主，采用锻锤、液压机等锻造设备对坯料进行成形加工，获得合格锻件。 自由锻的基本工序包括镦粗、拔长、冲孔、切割、弯曲、扭转、错移及锻接等。自由锻采取的都是热锻方式。

Free forging is in the production of small quantities of forgings， the forging， hydraulic press forging equipment is carried out on the blank forming process， obtain qualified forgings. The basic process of free forging including upsetting，forging， stretching， punching， cutting， bending， torsion， displacement and welding etc.. The free forging is all hot forging.

低塑性拔长时，forging设备，应注意选择合适的送进比，送进比太小时，变形集中在上下部，中心都锻不透，并沿轴向产生拉锻造应关于锻件的一些基本知识力，导致内部横向裂纹产生。在镦粗时，常用软衬垫镦粗或叠镦（用于锻薄饼形零件），以改善变形的不均匀性，防止产生表面裂纹。

When low plasticity is pulled out， attention should be paid to selecting suitable delivery ratio， sending too much time， deformation  on the upper and lower parts， and the center can not be built， and forging along the axial direction should be related to some basic knowledge of forging， resulting in the occurrence of internal transverse cracks. In the upsetting， commonly used soft liner (for upsetting or folding upsetting forging thin pancake， uneven parts) to improve the deformation， prevent the generation of cracks on the surface.
