Technical Field

[0001] The invention belongs to the field of shipbuilding, relates to the manufacture of a heat-insulating layer, and in particular to a corner plate forming device. Background Art

[0002] The cargo holds of LNG (Liquefied Natural Gas) vessels require two layers of thermal insulation to maintain an absolute low temperature of -163°C.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is described in detail in the following embodiments with reference to the accompanying drawings.

[0026] Example 1

[0027] Figure 1 It is a schematic diagram of the three-dimensional structure of the corner panel forming equipment in this embodiment.

[0028] like Figure 1 As shown, this embodiment provides a corner panel forming device for gluing and pressing the sub-layer member 1 and the FSB2 on the front side of the sub-layer member 1, including a press 10, a first pressing head 20, a first lower mold 30, and a conveyor 40.

[0029] The press 10 includes a frame 11 and a lifting mechanism 12 mounted on top of the frame 11. The lifting mechanism 12 is used to drive the pressing head to rise and fall. In this embodiment, the lifting mechanism 12 includes a servo motor 121, a dual-axis reducer 122, two first worm gear screw lifts 123, and two first connecting shafts 124. The servo motor 121 and the dual-axis reducer 122 are connected and mounted at a central position on the top of the frame 11. The two first worm gear screw lifts 123 are mounted on the top of the frame 11 and are distributed on both sides of the servo motor 121 and the dual-axis reducer 122. The input ends of the two first worm gear screw lifts 123 are respectively connected to the two output ends of the dual-axis reducer 122 via the first connecting shafts 124. When the servo motor 121 is working, the servo motor 121 drives the dual-axis reducer 122, and the dual-axis reducer 122 drives the screws of the two first worm gear screw lifts 123 to rise and fall synchronously via the two first connecting shafts 124.

[0030] The first ram 20 is raised and lowered by the lifting mechanism 12. Specifically, the top of the first ram 20 is detachably connected to the screws of two first worm gear screw elevators 123, allowing for replacement of the first ram 20. The first ram 20 includes an elastic element that contacts and evenly applies pressure to the corner panel components, eliminating errors and ensuring precise corner panel formation.

[0031] Figure 2 FIG. 2 is a schematic diagram of the three-dimensional structure of the first pressing head 20 in this embodiment.

[0032] like Figure 2 As shown, in this embodiment, the first pressing head 20 includes a frame body 21, two pressing head mounting frames 22, multiple first lifting angle adjustment mechanisms 23, a first synchronous drive mechanism 24, two airbag pressing heads 25, and two pressing head position adjustment mechanisms 26.

[0033] The top of the frame body 21 is detachably connected to the screws of the two first worm gear screw elevators 123. Two ram mounting frames 22 are symmetrically arranged on either side of the frame body 21, with adjacent sides hinged to the bottom of the frame body 21. Multiple first lift angle adjustment mechanisms 23 are evenly distributed along the length of the frame body 21. Each first lift angle adjustment mechanism 23 is connected to two ram mounting frames 22 and is used to adjust the angle between the two ram mounting frames 22. A first synchronous drive mechanism 24 is mounted on the frame body 21 and connected to the multiple first lift angle adjustment mechanisms 23. The first synchronous drive mechanism 24 is used to synchronously drive the multiple first lift angle adjustment mechanisms 23. Two airbag rams 25 are mounted on the bottom surfaces of the two ram mounting frames 22, respectively. Two ram position adjustment mechanisms 26 are mounted on the two ram mounting frames 22 and are respectively connected to the two rams 25. The two ram position adjustment mechanisms 26 are used to drive the adjacent sides of the two rams 25 closer together or farther apart.

[0034] Each first lifting angle adjustment mechanism 23 includes a second worm gear screw lift 231, a lifting slider 232, and two connecting rods 233. The second worm gear screw lift 231 is mounted on the frame body 21. The screw of the second worm gear screw lift 231 is connected to and drives the lifting slider 232 to move up and down. One end of the two connecting rods 233 is hinged to the two sides of the lifting slider 232, and the other end of the two connecting rods 233 is hinged to the top surface of the two pressure head mounting frames 22.

[0035] The first synchronous drive mechanism 24 includes multiple second connecting shafts 241 and a handle 242. Each adjacent second worm gear screw elevator 231 is connected by a second connecting shaft 241, and the handle 242 is connected to the second worm gear screw elevator 231 at the end via a second connecting shaft 241. A clamping member 243 is also provided on the second connecting shaft 241 connected to the handle 242. After the angle between the two pressure head mounting frames 22 is adjusted and the handle 242 is released, the clamping member 243 clamps the second connecting shaft 241 connected to the handle 242, thereby locking the second connecting shaft 241.

[0036] Each airbag pressing head 25 includes a pressing plate 251 and a sheet-like airbag 252 mounted on the bottom surface of the pressing plate 251. The sheet-like airbag 252 is an elastic element, which is made of a composite material with certain elasticity and tension.

[0037] Each pressure head position adjustment mechanism 26 includes multiple linear guide rails 261 and a trapezoidal screw mechanism 262. The multiple linear guide rails 261 are installed on the bottom surface of the pressure head mounting frame 22. The slider of each linear guide rail 261 is connected to the pressure plate 251 of the airbag pressure head 25. The screw nut of the trapezoidal screw mechanism 262 is connected to the pressure plate 251 of the airbag pressure head 25 through a connecting member 263, which is used to drive the airbag pressure head 25 to move along the linear guide rail 261.

[0038] like Figure 1 As shown, the first lower die 30 is located directly below the first pressing head 20 and is used to carry the workpiece to cooperate with the downward pressing of the first pressing head 20. In this embodiment, the first lower die 30 includes a first base 31, two support panels 32, and a plurality of retractable adjustment rods 33. The two support panels 32 are symmetrically mounted on the first base 31 and respectively correspond to the two pressing head mounting frames 22 of the first pressing head 20. The adjacent sides of the two support panels 32 are hinged on the first base 31. The opposite sides of the two support panels 32 are connected to the first base 31 through the plurality of retractable adjustment rods 33. The opposite sides are supported by the plurality of retractable adjustment rods 33 and are higher than the adjacent sides. The angle between the two support panels 32 can be adjusted by adjusting the length of the plurality of retractable adjustment rods 33.

[0039] The conveyor 40 is provided below the press 10 for transporting the first lower mold 30 and allowing the first lower mold 30 to be replaced.

[0040] Before using this corner panel forming machine, the angle between the two ram mounting brackets 22 of the first ram 20 and the angle between the two support panels 32 of the first lower mold 30 must be adjusted to match the angle of the sub-layer component 1. Next, place the sub-layer component 1 on the first lower mold 30, with the two support panels 32 resting on the back side of the sub-layer component 1. Next, apply glue to the two upward-facing surfaces (i.e., the front side) of the sub-layer component 1 and cover them with FSB2. Afterwards, the first lower mold 30 is transported by conveyor 40 to directly below the first ram 20, and the corner panel forming machine can begin operation.

[0041] During operation, the press 10 drives the first pressing head 20 downward, causing the inflated sheet-like airbag 252 to contact the FSB2 on the front surface of the secondary layer 1. The FSB2 and secondary layer 1 are then pressed together against the first lower mold 30 for curing. After curing is complete, the conveyor 40 can transport the first lower mold 30 away.

[0042] Example 2

[0043] Figure 3 It is a schematic diagram of the three-dimensional structure of the corner panel forming equipment in this embodiment.

[0044] like Figure 3As shown, this embodiment provides a corner panel forming device for gluing and pressing the FSB2 on the front of the main layer 3 and the secondary layer 1, including a press 10, a second pressing head 50, a first lower mold 30, and a conveyor 40. The difference from Example 1 lies in the second pressing head 50.

[0045] The second pressing head 50 has an elastic element, which is used to contact parts of the corner plate and apply pressure evenly, thereby eliminating errors and ensuring accurate molding of the corner plate.

[0046] In this embodiment, the second ram 50 includes a first frame 51, a plurality of annular airbags 53, a second frame 52, and a plurality of elastic blocks 54, which are connected sequentially from top to bottom. The first frame 51 and the second frame 52 are both beam-shaped and arranged parallel to each other. The top of the first frame 51 is detachably connected to the screws of the two first worm gear screw elevators, ensuring that the second ram 50 can be replaced. The plurality of annular airbags 53 are connected to the bottom of the first frame 51 at equal intervals along the length. The upper end surface of each annular airbag 53 is connected to the bottom of the first frame 51. The top of the second frame 52 is connected to the lower end surfaces of the plurality of annular airbags 53. The bottom of the second frame 52 is connected to the plurality of elastic blocks 54. The plurality of elastic blocks 54 are arranged in two rows symmetrically about the midline of the width of the second frame 52. The elastic blocks 54 in each row are evenly spaced along the length of the second frame 52 and are tilted with their lower ends facing away from the midline of the width of the second frame 52. Among them, the annular airbags 53 and the elastic blocks 54 are elastic elements. The two rows of elastic blocks 54 are used to contact the parts of the corner panels. The material of the elastic blocks 54 is preferably polyurethane of the same material as the main layer 3. Multiple annular airbags 53 are used to ensure that the two rows of elastic blocks 54 apply uniform pressure to the parts.

[0047] Before using this corner panel forming machine, the pressing head on the press 10 must be replaced with a second pressing head 50. The first lower mold 30 and the workpiece to be bonded, which are the main layer 3, can be the same as those removed by the conveyor 40 in Example 1. Glue is applied to the FSB2 surface of the processed workpiece, and the main layer 3 is placed on top of it, positioned at the angle. The first lower mold 30 is then transported by the conveyor 40 to the position directly below the second pressing head 50, and the corner panel forming machine can then begin operation.

[0048] During operation, the press 10 drives the second pressing head 50 downward, causing the two rows of elastic blocks 54 to contact the two upward-facing surfaces of the primary layer 3. The inflated annular airbag 53 then presses the primary layer 3, FSB 2, and secondary layer 1 together against the first lower mold 30 for lamination and curing. After curing is complete, the conveyor 40 can transport the first lower mold 30 away.

The difference from Example 1 lies in the second lower mold 60.

[0052] Figure 5 : is a schematic diagram of the three-dimensional structure of the second lower mold 60 in this embodiment, Figure 6 It is a schematic diagram of the three-dimensional structure in which the second lower mold 60 hides the second base 61 and is inverted in this embodiment.

[0054] The structure of the mold frame body 62, two mounting brackets 63, multiple second lifting angle adjustment mechanisms 64, and second synchronous drive mechanism 65 is similar to that of the first ram 20. The components and connections of each component can be found in the corresponding sections of Example 1 and will not be further described here. The operating principle is also consistent with that of the first ram 20. The second synchronous drive mechanism 65 drives the multiple second lifting angle adjustment mechanisms 64 to operate synchronously, changing the angle between the two mounting brackets 63 to match the angle of the workpiece's sub-layer 1. The mold frame body 62 is mounted on a second base 61. The bottom of the mold frame body 62 has multiple support brackets 621 distributed along its length. Each support bracket 621 is provided with a pin hole 6211. The second base 61 also has corresponding pin holes. The multiple support brackets 621 and the second base 61 are positioned and connected to each other via latches and pin holes.

Each first clamping mechanism 66 is fixed in the length direction (X-axis direction in the figure) of the mounting frame 63 and can be adjusted and moved in the width direction (Y-axis direction in the figure). Specifically, each first clamping mechanism 66 includes a first Y-axis linear guide 661, a first clamping seat 662, and a first Y-axis trapezoidal screw mechanism 663. Among them, the slide rail of the first Y-axis linear guide 661 is mounted on the top surface of the mounting frame 63, the first clamping seat 662 is mounted on the slider of the first Y-axis linear guide 661, the first clamping seat 662 is used to clamp the sub-layer component 1 and is provided with a socket 6621 for cooperating with the plug rod to connect the sub-layer component 1. The screw seat of the first Y-axis trapezoidal screw mechanism 663 is mounted on the mounting frame 63, and the nut of the first Y-axis trapezoidal screw mechanism 663 is connected to the first clamping seat 662. When it is necessary to adjust the position of the first clamping seat 662 in the width direction of the mounting frame 63, the matching handle is installed on the end of the trapezoidal screw of the first Y-axis trapezoidal screw mechanism 663, and the handle is manually operated to adjust it. After adjusting it into place, the handle is removed and the trapezoidal screw can self-lock.

[0057] The two second clamping mechanisms 67 are symmetrically mounted on the top surfaces of the two mounting frames 63. Each second clamping mechanism 67 is adjustable and movable in the length direction (X-axis direction in the figure) and the width direction (Y-axis direction in the figure) of the mounting frame 63. Specifically, each second clamping mechanism 67 includes an X-axis linear guide 671, a clamp 672, a Y-axis mounting seat 673, a second Y-axis linear guide 674, a second clamping seat 675, and a second Y-axis trapezoidal screw mechanism 676. The slide rail of the X-axis linear guide 671 is mounted on the top surface of the mounting frame 63, the clamp 672 is mounted on the slide rail of the X-axis linear guide 671, and the Y-axis mounting seat 673 is mounted on the slider of the X-axis linear guide 671 and the clamp 672. The clamp 672 is used to lock the position of the Y-axis mounting seat 673 on the slide rail of the X-axis linear guide 671. The slide rail of the second Y-axis linear guide 674 is mounted on the Y-axis mounting seat 673. The second clamping seat 675 is mounted on the slider of the second Y-axis linear guide 674. The second clamping seat 675 is used to clamp the secondary component 1 and is also provided with a socket for connecting the secondary component 1 with a rod. The screw seat of the second Y-axis trapezoidal screw mechanism 676 is mounted on the Y-axis mounting seat 673, and the nut of the second Y-axis trapezoidal screw mechanism 676 is connected to the second clamping seat 675. When the position of the second clamping seat 675 in the longitudinal direction of the mounting frame 63 needs to be adjusted, the clamp 672 is released, the Y-axis mounting seat 673 is moved, and the clamp 672 is locked after it is moved into position. When the position of the second clamping seat 675 in the width direction of the mounting frame 63 needs to be adjusted, a matching handle is installed at the end of the trapezoidal screw of the second Y-axis trapezoidal screw mechanism 676. The handle is manually operated to adjust the position. After the handle is adjusted into position, the trapezoidal screw can be self-locking.

[0058] Before using this corner panel forming equipment, the press head must be replaced with the first press head 20 and the angle between the two press head mounting brackets of the first press head 20 must be adjusted to match the angle of the sub-layer component 1. The second lower die 60 must be adjusted and the workpiece clamped to the second lower die 60. This workpiece can be the workpiece processed in Example 2. Specifically, the second synchronous drive mechanism 65 is first operated to drive the multiple second lifting angle adjustment mechanisms 64 to operate synchronously, so that the angle between the two mounting brackets 63 matches the angle of the sub-layer component 1. The first clamping seats 662 of the two first clamping mechanisms 66 and the second clamping seats 675 of the two second clamping mechanisms 67 are then adjusted to correspond to the four corners of the sub-layer component 1. The workpiece is then placed on the sub-layer component 1 and the clamping seats and sub-layer component 1 are connected with a rod. This completes the workpiece clamping. Glue is then applied to the two upward-facing surfaces (i.e., the back surface) of the sub-layer component 1 and covered with FSB4. Afterwards, the second lower mold 60 is transported to the position directly below the first pressing head 20 by the conveyor 40 , and the corner panel forming equipment can start working.

[0059] During operation, the press 10 drives the first pressing head 20 downward, causing the inflated sheet-like airbag to contact the FSB 4 on the back of the secondary layer 11. This pressurizes the FSB 4 and the secondary layer 1 together against the second lower mold 60 for lamination and curing. After curing is complete, the conveyor 40 can transport the second lower mold 60 away.
