Abstract
The invention discloses a jacking device for an army product dog-ear concave outer plate on a ship, which comprises: the top plate is provided with a cambered surface and is used for propping against the concave part of the concave outer plate; and one end of the driving mechanism is fixedly connected with the top plate, and the other end of the driving mechanism is fixed on the support. The invention aims at solving the problems that after the bevel is welded, the shot is unqualified, and the inward concave deformation generated after the welding reworking is carried out again is used for correcting the bevel, thereby reducing the time and the manual difficulty brought by the cutting and the reworking of an assembler.
Description
Technical Field
The invention belongs to the field of ships, and particularly relates to a jacking device for an army article folded angle concave outer plate on a ship.

Along with the construction of military ships, the line type fairing of the outer plate is particularly emphasized. The edges and corners of military vessels are more, and the first-time qualification rate cannot be guaranteed by electric welding shooting, so that the number of returned pieces is more. As long as the bevel is welded by electric welding, the bevel will be inwards concave. The outer plate will be non-smooth.
Disclosure of Invention
The invention provides a jacking device for a military product bevel indent outer plate on a ship, aiming at solving the problems in the prior art, and aiming at solving the problems that after bevel electric welding is finished, a picture is unqualified, and the bevel indent outer plate is corrected by indent deformation generated after electric welding reworking is carried out again, so that the time and manual difficulty brought by cutting and reworking by an assembler are reduced.
In order to achieve the purpose, the invention adopts the following technical scheme:
a device for flattening an outer concave plate of a military product bevel on a ship, comprising: the top plate is provided with a cambered surface and is used for propping against the concave part of the concave outer plate; and
and one end of the driving mechanism is fixedly connected with the top plate, and the other end of the driving mechanism is fixed on the support.
Preferably, the top plate is a flat iron having a predetermined circular arc.
Preferably, the driving mechanism is 1 or 2 oil pumps of 10 t.
Preferably, the flat iron with the predetermined circular arc is 500 mm long, 100 mm wide and 15 mm thick.
Preferably, the perpendicular distance between the midpoint of the predetermined circular arc and the line connecting the two end points of the predetermined circular arc is 10 mm.
Preferably, the bracket is formed by welding flat iron or angle iron.
A use method of a leveling device of an army corner concave outer plate on a ship comprises the following steps: processing the concave outer plate to a preset temperature; the fixed bracket enables the cambered surface of the flat iron with the preset circular arc to abut against the concave part of the inner concave outer plate, and further enables the middle point of the circular arc to abut against the geometric center of the concave part; the oil pump drives the flat iron to push the inner concave outer plate; and removing the jacking device after the concave outer plate is cooled to normal temperature.
Preferably, the predetermined temperature is 350-550 ℃.
Preferably, the predetermined temperature is 450 degrees celsius.
Compared with the prior art, the invention has the beneficial effects that: when the folded angle of the outer plate is heated to 450 deg., the outer plate is pressed by the device to elongate the molecular structure. When the steel plate is naturally cooled and the molecular structure is stable, the device is disassembled, and the concave outer plate can be restored to be flat.
