Technical field
The present invention relates to a kind of building material machinery manufacturing technology field more particularly to a kind of Transmission of Super-Long Large Diameter concrete tubular pile steel
Mould machining deformation accuracy control method.
Background technique
Pipe pile steel mold is the main consumption of the architectural engineerings complete set of equipments such as city capital construction, large bridge, harbour construction
Damage component, the construction for architectural engineering pretensioning prestressed concrete pile.Punching block usually by length up to 8000~55000mm,
The upper and lower mould of 300~1400mm of diameter molds, and upper die and lower die constitute the welding with certain rigidity using welding manner
Structure.Punching block manufacture need to guarantee that upper lower shell can be molded accurately, water-tight mud in operational process, be easy to clear mould again with finishing.
Since cast-in-place concrete need to be through high speed rotation centrifugal forming, thus to barrel lenght direction concentricity with higher and straight
Dimension requirement.However the manufacture of punching block processing need to be suppressed and be produced in deformation process through processes such as the compression moulding of special pressure machine, welding
Thermal deformation caused by raw rebound and welding processing frequently results in punching block and generates excessive straightness and coaxiality deviation, to make
It generates and is eccentrically rotated in casting process, the size for influencing the normal operation for being centrifuged complete set of equipments and being poured tubular pole product.
Traditional punching block processing method is formed using the more piece barrel soldering no more than 2 meters long, and straightness and bias are caused
