Problems solved by technology

[0002] At present, in the chord processing and forming technology for the pile leg of the offshore drilling platform, the longer steel plate is stamped into a semicircle, and the thicker plate is formed, due to the high yield strength of the chord itself and the large deformation during the forming process , needs to be preheated to a relatively high temperature. Generally, the steel plate is heated to above 950°C for forming. Annealing, processing, increase the manufacturing cost of the chord

Abstract

The invention provides an upper moulding bed. The upper moulding bed comprises an elongated upper moulding bed body, wherein the upper surface of the upper moulding bed body is a plane; the lower surface of the upper moulding bed body is an arc surface; the upper moulding bed body comprises a transition section and a forming section which are connected to each other along the axial direction; the transition section comprises a front free end and a connecting end connected with the forming section; the arc surface of the transition section is gradually expanded from the free end to the connecting end; and the arc shape of the cross section of the connecting end is the same with that of the cross section of the forming section. The invention also provides a chord cold pressing forming device. By the upper moulding bed, the manufacturing cost is reduced, a technological process is simplified, and a required reduction force is reduced. The chord cold pressing forming device is suitable for forming long and thick chords.

Description

technical field [0001] The invention relates to the technical field of cold-press forming of chords for pile legs of offshore drilling platforms, in particular to an upper tire mold and a chord cold-press forming device for multiple cold-press forming of chords for pile legs of offshore drilling platforms. Background technique [0002] At present, in the chord processing and forming technology for the pile leg of the offshore drilling platform, the longer steel plate is stamped into a semicircle, and the thicker plate is formed, due to the high yield strength of the chord itself and the large deformation during the forming process , needs to be preheated to a relatively high temperature. Generally, the steel plate is heated to above 950°C for forming. Annealing and processing increase the manufacturing cost of the chord. [0003] In view of the above-mentioned limitations existing in the existing chord cold forming process, the technical designer, based on years of rich pra...
