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 aft

Example Embodiment

[0105] In Example 1, the production process of the centrifugal concrete pile mold is as follows:

[0106] First, prepare the following components:

[0107] Match-and-groove board: The strip-shaped board is pickled, removed the oxide scale, and cold-drawn directly to the fine size. After correction, the loop bolt eye is laid and set aside;

[0108] Tube wall: The hot-rolled sheet is directly and accurately cut into a rectangle of the required size by a shearing machine, and then pressed into a shape by a press for use

[0109] Longitudinal ribs and ring ribs: cut the hot-rolled sheet into strips of the required size for use;

[0110] Loops, bolts: spare

[0111] End plate: The strip-shaped plate is bent and formed by a press to obtain a ring-shaped plate for use;

[0112] Running wheel: The strip-shaped sheet is bent and formed by a press to form the outer ring of the running wheel; the strip-shaped sheet of another size is bent as the running wheel inner ring support plate, and th...

Example Embodiment

[0126] In Example 2, the production process of the centrifugal concrete pile mold is as follows:

[0127] 1. Prepare the following components:

[0128] Match-and-groove board: the strip-shaped board is pickled, the oxide scale is removed, and the cold-drawn die is directly cold-drawn to the fine size. At the same time, the tongue-and-groove plane trapezoidal groove is pulled out, and after correction, the loop bolt eye is laid for use;

[0129] Pipe wall: Cut the hot-rolled plate into a rectangle of the required size by a shearing machine, reserve the processing amount, and then press it into a long groove with a cross-section of the required shape on the press, and use gas cutting to cut it or metal cutting. The excess part of the end face of the joint is reserved;

[0130] Longitudinal ribs and ring ribs: cut the hot-rolled sheet into strips of the required size for use;

[0131] Loops, bolts: spare

[0132] End plate: The strip-shaped plate is bent and formed by a press to obta...

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....
