FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and can be used in hydraulic presses. Cylinder housing has a cylindrical section, thrust flange and recess. The latter is arranged nearby thrust flange. Cylindrical section ID-to-OD ratio makes 0.68 to 0.72. Recess features four smoothly mating profiles, each being formed by radius depending upon wall thickness h on cylindrical section of the housing. First of aforesaid profiles is formed by radius of 0.17 h on angle of 50°. Other profiles are made with radii of 0.33 h on angle of 30°, 0.7 h on angle of 20° and 0.2 h on angle of 30°.
EFFECT: simplified process.
