Cutting jig frame for toothed plate of pile leg

Abstract

The invention discloses a cutting jig frame for a toothed plate of a pile leg. The cutting jig frame comprises a base 1, gas pipelines 2, fixed rib plates 3, supporting rib plates 4, gas nozzles 5, vertical supporting plates 6 and slidable locking structures 7; the base 1 is cuboid, a plurality of uniformly distributed cuboid grooves passing through the top end and the bottom end are sequentially formed in the surface along the wide side of the base 1, and the top end surface , located between two adjacent cuboid grooves, of the base 1 is provided with the plurality of slidable locking structures 7 in a slidable connection way; the supporting rib plates 4 and the corresponding vertical supporting plates 6 are respectively located on the same straight line; one side of each supporting rib plate 4 is provided with one of the fixed rib plates 3 in a welding fixation way; and each of two sides located at long sides of the base 1 is provided with one of the gas pipelines 2. By using the cutting jig frame, the position of a flat metal plate required to be cut can be regulated and fixed, and the cutting size precision and cutting quality of the toothed plate can be ensured; and the cutting jig frame can be suitable for cutting raw material steel plates with different widths.

Description

technical field [0001] The invention belongs to the technical field of jack-up drilling platform pile leg manufacturing, and in particular relates to a pile leg tooth-shaped plate cutting tire frame. Background technique [0002] The main side tube of the jack-up drilling platform pile leg is composed of a toothed plate and a round tube, and the toothed plate needs to be cut by a CNC cutting machine according to the tooth shape. Due to the uneven heating of the steel plate during the cutting process, it is easy to cause cutting deformation of the cut toothed plate, so that the dimensional accuracy cannot meet the manufacturing accuracy requirements of the main side pipe. In addition, the existing type of tire frame can only be used for raw steel plates of the same width, and needs to be remade for raw steel plates of different widths. Contents of the invention [0003] The invention provides a rack for cutting the toothed plate of pile legs, which can adjust and fix the p...
