Axle axle shaft sleeve reducing and expanding device

An axle shaft sleeve reducing and expanding device relates to the technical field of reducing and expanding treatment of metal pipe fittings and comprises a horizontally-arranged square workbench, and a swing feeding assembly, a clamping and transferring assembly, a reducing assembly and an expanding assembly are arranged on the square workbench. The problems that when equipment in the prior art is used for hot compression expanding treatment of the axle shaft sleeve, the function is single, feeding and discharging operation is difficult, clamping is inconvenient, and multi-stage expanding forming cannot be achieved are solved. 车桥半轴套管缩扩径装置，涉及金属管件的缩扩径处理技术领域，包括水平设置的方形工作台，所述方形工作台上分别设有摆动上料组件、夹持转移组件、缩径组件和扩径组件。本发明解决了传统技术中的设备在用于半轴套管的热压缩扩径处理时，存在的功能单一、上下料操作困难、夹持不便以及无法实现多级扩径成型等问题。
