Problems solved by technology

The cutting accuracy of this method is poor, resulting in a large amount of trimming of assembled bulb flat steel (the trimming rate is as high as 90%), which will inevitably lead to waste of man-hours, increase of construction cost, and reduction of construction efficiency.

Embodiment Construction

[0014] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] see figure 1 and figure 2 , the invention discloses a hole-opening mold for a spherical flat steel mooring seat, which is characterized in that: it includes a mold body 1, and the mold body 1 is provided with a hole contour 2, and the hole contour 2 is cut according to a design template , and a 5mm cutting compensation value is placed around; the opening profile 2 has a semicircular arc ignition and extinguishing opening 6, with fixing members 4 on the left and right sides, and positioning elements 3 on the front and rear sides.

[0016] Further, the fixing member 4 is a fixing bolt or an electromagnet, and a lifting mechanism 5 is provided between the electromagnet and the mold body 1 for adjusting the height of the mold body; Position groove, the limit rod is slidingly embedded with a limit rod, and the upper end of the limit rod ...

Abstract

The invention discloses a flat-bulb steel mooring seat trepanning die. The flat-bulb steel mooring seat trepanning die comprises a die body. A trepanning outline is formed in the die body and formed through cutting according to a design template, and the cutting compensation value of 5 mm is additionally added on the periphery. The trepanning outline is provided with a semicircular arc striking and extinguishing hole, fixing components are arranged on the left side and the right side of the trepanning outline, and positioning elements are arranged on the front side and the rear side of the trepanning outline. By means of the flat-bulb steel mooring seat trepanning die, the cutting efficiency can be improved, and work hours are saved; mooring seat cutting trepanning can be finished in a high-precision and high-quality manner at a time, field assembling trimming is avoided, work hour waste is reduced, and therefore the segmented construction efficiency and quality are improved.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and relates to a hole-opening mold for a mooring seat of a spherical flat steel. Background technique [0002] The H1742A series ship is a large amphibious landing ship with a total of 1,100 mooring seats for helicopters and tanks of seven types: A, B, C, D, E, F, and G. This requires cutting special openings through the frame of the mooring seat. This problem can be solved by CNC cutting the plate parts, but since the ship is not modeled, the mooring openings of the bulb flat steel must be cut manually To be done. In the previous processing, the relevant construction personnel were to barge the wooden template line to the flat steel web, and then cut it out manually with a cutter. The cutting accuracy of this method is relatively poor, resulting in a large amount of trimming of assembled bulb flat steel (the trimming rate is as high as 90%), which will inevitably cause waste of man-hours,...
