The invention discloses an upper mold assembly of a corrugated pipe forming machine. The upper mold assembly comprises an upper mold base and an oil cylinder arranged on the upper mold base. A pistonrod of the oil cylinder is used for driving an upper mold head to move up and down. An upper base is arranged on the upper mold base. A downward pressing threaded rod vertically and movably penetratesthe upper base and is fixed to a downward pressing threaded sleeve. The downward pressing threaded sleeve moves up and down along an inner hole of the upper base. The lower end of the downward pressing threaded rod is connected with the upper mold head. The downward pressing threaded sleeve is connected with a first spring limiting the downward displacement amount of the downward pressing threaded sleeve and achieving upward resetting of the downward pressing threaded sleeve. Due to the adoption of the technical scheme, when the downward pressing threaded rod conducts downward pressing, the first spring is compressed, the compression amount of the first spring can be regulated through a regulation nut, locking can be conducted through a locking nut after regulation is conducted through the regulation nut in place, and therefore the downward pressing amount of the upper mold head can be effectively controlled.
Description
technical field [0001] The invention relates to the technical field of metal bellows processing, in particular to a bellows forming machine. Background technique [0002] The current bellows forming machine is a device that generates hydraulic pressure by an oil pump unit, and controls hydraulic accessories such as solenoid valves and oil cylinders through an electronic control system to drive mechanical components for hydraulic forming. In the forming process of bellows, traditional forming equipment has the characteristics of simple operation and low price, but these traditional forming equipment have some safety and design deficiencies. If the pressing amount of the upper die cannot be controlled, it will affect the molding quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an upper die assembly of a bellows forming machine, which solves the problem that the existing forming machine cannot adjust the pr...
