[CN201721475969.X] A device for sinking special materials of powder product hydraulic press Title: A device for sinking special materials of powder product hydraulic press Application number: CN201721475969.X Applicant: Nantong Heqiang Hydraulic Technology Co., Ltd. Application date: 2017-11-8 Patent type: Utility model This utility model relates to a device for sinking special materials of powder product hydraulic press, it includes a main body piston rod, a small adjustment pad, a large adjustment pad, a cylinder port guide sleeve, an upper cavity oil port, a piston rod, a lower cavity oil port, a cylinder body, a limit nut, and a locking plate. The main body piston rod is the carrier for installing this material sinking device. Small and large adjustment pads are sleeved below the main body piston rod, and a cylinder is designed below the large adjustment piston rod pad, the cylinder is equipped with a seal, which forms an upper and lower closed space together with the piston rod and can withstand liquid pressure. A cylinder port guide sleeve is designed between the upper end of the cylinder and the piston rod, and the right side of the cylinder is respectively designed with oil inlet. The bottom of the main piston rod is designed with a limit nut, and the lower part of the limit nut is designed with a locking piece, which has the advantages of less process and improved production efficiency; at the same time, the controllable ejection height of the bottom limit nut can be adjusted to make it suitable for different products and needs.
