Abstract

The invention discloses a hydraulic cauldron hoop and upper flange tooth profile structure and manufacturing method, and belongs to the fields of quick-opening engaged tooth type pressure bearing equipment designing and manufacturing. According to the hydraulic cauldron hoop and upper flange tooth profile structure and manufacturing method, the upper end surface of a hoop and the upper end surfaceof an upper flange are vertically clamped, fixed and aligned in the final stage tooth profile machining procedure of a loop and upper flange assembly; by adopting a large-size cylindrical milling cutter and a CNC boring and milling machine, tooth profiles are machined, and tooth roots are subjected to rough machining; the tooth roots are subjected to finish machining through a small-size cylindrical milling cutter; and tooth profile template checking is conducted. Through the hydraulic cauldron hoop and upper flange tooth profile structure and manufacturing method, the problems that a previous hydraulic cauldron hoop and upper flange tooth profile design structure is poor in manufacturability, the stress is high, procedures are complex, the product quality is poor, the production efficiency is low, and the manufacturing cost is high are effectively solved.

Description

technical field [0001] The invention relates to a hydraulic kettle clamp and an upper flange tooth structure and a manufacturing method, and belongs to the design and manufacturing field of quick-opening rod-shaped pressure-bearing equipment. Background technique [0002] For a long time, hydraulic kettles with a quick-opening rod-shaped sealing and locking structure, after the upper flange assembly is loaded into the clamp from top to bottom, pass the inclined surface of the lower inclined block fastened on the outer teeth of the upper flange and the inner teeth of the clamp. The oblique surface of the lower fastened upper inclined block is circumferentially tightened to seal and lock the sealing surfaces of the upper flange assembly and the lower flange assembly. Wherein the hoop is formed by two hoop half-rings and lug assemblies tightened by fasteners and pin shafts. The inner circle of the clamp and the outer circle of the upper flange have 16 or 18 teeth that are even...
