Centrifugal concrete pile die production process

Abstract

The invention relates to a method for producing eccentric concrete post mould, wherein it comprises that: first, preparing needed elements as tube wall, longitudinal bar, annular bar, bolt, end plate, etc; then connecting and welding said elements; at least, finely processing half steel mould and whole mould, and turning integrity, to obtain the final product. The matched board and tube wall are cold drawn to fine size via cold drawer and mould, to save material and improve quality; the end plate and rolling wheel are made from plate bended by compressor to save steel.

Description

(1) Technical field: [0001] The invention relates to a production process of a centrifugal concrete pile form, in particular to a production process of a centrifugal concrete pile form for manufacturing prestressed concrete piles for construction. (two) background technology: [0002] Prestressed centrifugal concrete piles for construction include the most common prestressed centrifugal pipe piles and the most recent prestressed centrifugal square piles. Both of them are produced by rotating the centrifugal concrete pile form at a high speed on the centrifuge, so that the concrete contained in the centrifugal concrete pile form moves with the high-speed centrifugal movement of the mold to produce it, because it is convenient for large-scale industrial production and the produced prestressed concrete The pile has good compactness, high strength, and strong bearing capacity, and it has increasingly replaced the traditional production of concrete piles cast by vibration method....

Problems solved by technology

[0035] 2. The quality of mold products is not satisfactory:

[0036] 1) The plane trapezoidal groove of the tongue and groove board is planed and processed by a planer, and the processing accuracy is poor.

[0037] The steel mold is not well sealed during the production of pipe piles, and grout leakage occurs;

[0038] 2) The whole set of steel molds is a single-section steel mold obtained after single-section turning, which is connected one by one to form a complete set of steel molds. The overall coaxiality of the steel molds is poor, and the molds are easy to jump when the concrete piles are produced by a centrifuge. continue to produce

[0039] 3) The running wheel is a cast steel running wheel, which may have sand holes, which will affect the overall strength of the mold
