Design and experiment of hydroforming equipment for magnetic pump spacer

Aiming at the problems of magnetic pump isolation sleeve, such as various processing procedures, low efficiency, and surface quality can not be guaranteed, a fully automatic hydroforming machine was developed. First of all, analyze the characteristics of the magnetic pump isolation sleeve parts, formulate its hydraulic forming process and process, and propose the equipment functions and technical requirements in the automatic forming process. Secondly, according to the functional and technical requirements, the mechanical structure of the forming device is designed, the high-precision and continuously adjustable hydraulic system is developed, the automatic control system is built, and the parameters of the equipment can be set and controlled through the touch screen. Finally, through the prototype debugging, the equipment runs smoothly and reliably, meeting the design requirements. Through the hydroforming test, the formed parts have uniform wall thickness and good surface quality, which further verifies that the performance of the magnetic pump isolation sleeve forming equipment meets the requirements.
