Abstract

本发明设计了一种帽式缸底,特别是一种具有油路的帽式缸底,用于超液压油缸的缸底。它由销轴1?缸底体2?定位套3。由模具一次性锻压而成,可以提高缸底内部晶粒的密实度。与现有的产品相比不仅使用方便、结构简单、成本低,提高了该类液压油缸的工作稳定性,可避免焊接损伤而导致的漏油等问题。
The invention discloses a hat type cylinder bottom and particularly relates to a hat type cylinder bottom provided with an oil way. The hat type cylinder bottom is used for an ultra-hydraulic oil cylinder. The hat type cylinder bottom is composed of a pin shaft 1, a cylinder bottom body 2 and a positioning sleeve 3. The hat type cylinder bottom is formed through one-time forging and pressing by a die, and the compactness of internal crystalline grains of the cylinder bottom can be improved. Compared with an existing product, the hat type cylinder bottom is convenient to use, simple in structure and low in cost; the working stability of hydraulic cylinders of the type is improved, and the problems of oil leakage and the like due to welding damage can be avoided.
