Abstract
The invention relates to a liner plate tool for correcting a thin aluminum alloy plate. The liner plate tool for correcting the thin aluminum alloy plate comprises an aluminum plate and a steel plate, wherein one face of the aluminum plate is connected with the steel plate; at least one fixed groove is formed in the other face of the aluminum plate. The fixed groove in the toll can lock a welded joint, or stays close to the surface of a plate so as to play a role of a pad; the other side is mechanically knocked by a copper hammer and an aluminum hammer special for distortion correction by flame, so that the aims of correcting deformation of a hull, in particular to the aim of correcting a curved section are achieved.
Description
Technical field
The present invention relates to hull frock field, particularly relate to a kind of aluminium alloy sheet rectification liner plate frock.
Background technology
Compared with steel material, the thermal coefficient of expansion of aluminium alloy is large, is more easily out of shape.Under heating condition, the aluminium alloy deformation extent of different-alloy composition is different, there is epirelief and recessed deformation tendency.Therefore, when welding, aluminium alloy inevitably causes distortion.In the process that aluminium matter boats and ships are built at body section, multiple steps such as Production design, blanking processing, parts assembly, erection welding all may cause the distortion of hull.According to hull assembling and the guidance of welding procedure, after taking certain strengthening measure, the effect necessarily preventing the deformation of hull can be obtained.But due to design factors such as the physical and chemical performance of aluminium alloy itself and Ship Structures, Ship Structure still can inevitably generating portion distortion.
For the distortion of Ship Structure, generally need to utilize mechanical hammering, to heat and the method such as to operate on is corrected.For special complex-curved segmentation, "painted-face" character in opera or aluminium is only used to hammer mechanical hammering into shape, the required precision of body structure surface after very difficult guarantee straightening; Add heat straightening to segmentation, because sheet material is thinner, rectification distortion is wayward.
Summary of the invention
In view of this, be necessary the problem for correcting difficulty after the above-mentioned Ship Structure of aluminum alloy complex in the past welding equipment distortion, a kind of aluminium alloy sheet rectification liner plate frock is provided, correct in order to auxiliary deformation, distortion is effectively controlled, reaches the object ensureing the higher welding equipment quality of aluminium boat body structure.
For solveing the technical problem, adopt following technical scheme:
A kind of aluminium alloy sheet is corrected and is used liner plate frock, and comprise aluminium sheet and steel plate, the one side of aluminium sheet is connected with steel plate, and the another side of aluminium sheet is provided with at least 1 holddown groove.
Preferably, described holddown groove has 2, and 2 holddown grooves are mutually vertical.
Preferably, described holddown groove is U-type groove.
Preferably, described holddown groove surface finish.
Preferably, the width of described holddown groove is 12-15mm, and the degree of depth is 5-8mm.
Preferably, the thickness of steel plate is 8-12mm, and area is 200x160mm, and the thickness of aluminium sheet is 10-12mm, and area is 200x160mm.
Preferably, described steel plate and aluminium sheet are closely fixedly linked by bolt, nut and elastic washer, and described bolt is countersunk bolt, and countersunk bolt head is concordant with aluminium sheet, and nut is arranged on steel plate side, and elastic washer is between nut and steel plate.
Preferably, described aluminium alloy sheet rectification liner plate frock, also containing handle, described handle is positioned on steel plate.
Compared with prior art, the beneficial effect of aluminium alloy sheet rectification liner plate frock of the present invention is as follows:
(1) holddown groove in this frock can block weld seam, or is adjacent to plate surface, plays a part liner, and opposite side uses the special "painted-face" character in opera of plate fairing by hot working and aluminium hammer machinery to knock, and to reach the rectification deformation of hull, especially corrects the object of curved section.
(2) this frock practicality simple to operate, after having corrected, the fairing of Ship Structure outer surface, meets technological requirement.
Accompanying drawing explanation
Below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail.

Fig. 2 is the structural representation of holddown groove in a certain embodiment;
Fig. 3 is the B-B sectional view of Fig. 1.
In figure: 1-handle; 2-aluminium sheet; 3-steel plate; 4-bolt; 5-nut; 6-elastic washer; 7-holddown groove; 8-bolt hole.
Detailed description of the invention
In order to better the present invention is described, be described further below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of aluminium alloy sheet rectification liner plate frock, comprise aluminium sheet 2 and steel plate 3, the one side of aluminium sheet 2 is connected with steel plate 3, and the another side of aluminium sheet 2 is provided with at least one holddown groove 7.Preferably, the thickness of steel plate is 8-12mm, and area is 200x160mm; Steel plate 3 is unsuitable blocked up excessive, in order to avoid increase the weight of whole frock, increase labor strength, lavish labor on, steel plate material is not limit.The thickness of aluminium sheet is 10-12mm, and area is 200x160mm, and aluminium sheet material is not limit.
As shown in figures 1 and 3, conveniently use, aluminium alloy sheet rectification liner plate frock also comprises handle 1, and described handle 1 is positioned on steel plate 3.Preferably, in one embodiment of the invention, handle 1 is welded on the upper surface of steel plate 3, and the lower surface of steel plate 3 is connected with the upper surface of aluminium sheet 2, the lower surface of aluminium sheet 2 offers at least one holddown groove 7.
Described holddown groove 7 can block the weld seam of Ship Structure segmentation when correcting, and is preferably U-type groove, the structure of U-type groove and the reinforcement of ship hull weld joint similar, can block weld seam, ship hull plate can be blocked in all the other positions, rectification face.As shown in Figure 2, in one embodiment of the invention, described holddown groove 7 has two, and two holddown grooves 7 are mutually vertical.Preferably, the width of described holddown groove 7 is 12-15mm, and the degree of depth is 5-8mm, preferred, and the degree of depth of holddown groove 7 of having a try is 6mm.Preferred, the surface finish of described holddown groove 7, to make frock smooth surface, reduces the injury to hull mother metal in correcting process, also ensures the quality of correcting distortion.
Preferably, described steel plate 3 and aluminium sheet 2 are closely fixedly linked by bolt 4, nut 5 and elastic washer 6.Steel plate 3 and aluminium sheet 2 are drilled with 4 bolts hole 8, and the size of bolt hole 8 is φ=8mm.Described bolt 4 is countersunk bolt, and countersunk bolt head is concordant with aluminium sheet 2, and nut 5 is arranged on steel plate 3 side, and elastic washer 6 is between nut 5 and steel plate 3.When using countersunk bolt can avoid straightening, destroy the mother metal on body section surface.
