Description

Technical Field

[0001] The invention relates to the technical field of metal plate processing, and in particular to a processing device for a metal corrugated plate of a liquefied gas storage tank. Background Art

[0002] Liquefied natural gas (LNG) has been the preferred energy source for replacing oil with its advantages of being green, environmentally friendly and efficient, and has become one of the fastest growing energy industries in the world. With the rapid development of my country's economy and the continuous improvement of environmental governance requirements, the application and development of LNG has received more and more attention from all parties, thus triggering a rapid growth in the demand for clean energy in society. One of the key directions for the development of clean energy in China in the future is LNG.

[0003] LNG usually needs to rely on transportation equipment, such as ships and other marine equipment for transportation. The main components of an LNG receiving station are dock unloading, LNG storage, process processing and external transmission. Among them, the LNG storage tanks that undertake the storage task have the longest construction period, the most advanced technology, and the most difficulties in the construction process. They have always been managed as the key path of the entire project. In addition, the structural form and technological entrepreneurship of LNG storage tanks are also the focus of attention of domestic and international peers.

[0004] In LNG storage tanks, the corrugated plate used to form the sealing layer needs to be able to maintain good sealing and stability under various conditions of use. Therefore, the configuration and quality of the corrugated plate are particularly important, and the requirements for the process of manufacturing the corrugated plate are also high. In the existing process for manufacturing corrugated plates, the corrugations are made by a simple bending and stamping die. The material uniformity, smoothness and strength of the corrugated plates made in this way need to be improved at the corrugations, especially at the intersection of the horizontal and vertical corrugations.

[0005] In addition, the current processing device has many parts, and the parts need to be linked to synchronize during the processing, which makes the operation complicated and prone to failure. If any two parts fail to link or synchronize, processing defects are likely to occur, resulting in waste of blanks, so the processing yield needs to be further improved.

DETAILED DESCRIPTION

[0031] Now, with reference to the accompanying drawings, the specific embodiments of the present invention are described in detail. What is described here is only the preferred embodiment of the present invention, and those skilled in the art can think of other ways to implement the present invention based on the preferred embodiment, and the other ways also fall within the scope of the present invention.

[0032] The present invention provides a processing device for a metal corrugated plate, more specifically, the processing device is used to process a metal plate to form corrugations. The corrugated plate is suitable for manufacturing a storage container, and the storage container is particularly a liquefied gas storage tank of marine engineering equipment (such as a ship) or land engineering equipment, wherein the liquefied gas is, for example, liquefied natural gas (LNG), liquid nitrogen, liquid oxygen, liquid hydrogen, and liquid helium. An example of a corrugated plate is Fig.11As shown, the corrugated plate 200 is processed from a flat metal plate, and includes a metal plate body 201, a first corrugation 202, and a second corrugation 203. The protruding height of the first corrugation 202 relative to the metal plate body 201 is greater than the protruding height of the second corrugation 203 relative to the metal plate body 201, and the extension directions of the first corrugation 202 and the second corrugation 203 in the plane where the metal plate body 201 is located are approximately perpendicular. Therefore, the first corrugation 202 can also be called a large corrugation, and the second corrugation 203 can also be called a small corrugation. Preferably, the intersection 204 of the first corrugation 202 and the second corrugation 203 is also processed to form a knot feature to enhance the structural strength of the intersection 204.

[0033] In some embodiments, the second corrugation 203 (i.e., small corrugation) of the corrugated plate 200 is formed by the processing device according to the present invention. The first corrugation 202 (i.e., large corrugation) can be prefabricated by a pre-process. In some embodiments, both the first corrugation 202 and the second corrugation 203 can be formed by the processing device according to the present invention, for example, the first corrugation 202 and the second corrugation 203 are formed by two independent processes using the processing device according to the present invention.

[0034] Combine the following Figures 1 to 10C A preferred embodiment of the processing device is introduced.

[0035] First of all, it should be noted that the directional terms and positional terms mentioned in the present invention are only exemplary descriptions rather than restrictive descriptions. The description of the position of the component should be understood as a relative position rather than an absolute position, and the description of the extension direction of the component should be understood as a relative direction rather than an absolute direction. Among them, the directional terms and positional terms related to the processing device can be understood with reference to the characteristics of the corrugated plate 200 as the processing object, for example, the direction perpendicular to the plane where the corrugated plate 200 is located (roughly parallel to the metal plate body 201) is the first direction D1, the extension direction of the first corrugation 202 is the first corrugation direction D2, and the extension direction of the second corrugation 203 is the second corrugation direction D3. The first direction D1, the first corrugation direction D2 and the second corrugation direction D3 are basically orthogonal to each other.

[0036] like Figures 1 to 4 As shown, the processing device 1 includes a first die 10, a pressure plate 20 and a second die 30. The first die 10 is provided with a shaping recess 111, which is generally configured as a through-length groove and has a cross-sectional profile substantially the same as the corrugation to be processed and formed, and is used to receive the plastic deformation portion of the metal plate to form the corrugation during the processing. The pressure plate 20 is removably attached to the first die 10, and is used to clamp the metal plate to be processed between the pressure plate 20 and the first die 10, so that the metal plate remains fixed relative to the processing device 1 during the processing.

[0037] The second mold 30 is disposed on the side of the metal plate away from the first mold 10. That is, the first mold 10 and the second mold 30 are respectively located on both sides of the metal plate. According to the relative positions during the processing, the first mold 10 can also be called a lower mold, and the second mold 30 can also be called an upper mold. The second mold 30 includes a shaping protrusion 31, which is configured as a through-length protrusion disposed on the second mold body 33 and has a cross-sectional profile substantially the same as the corrugation to be processed and formed. Therefore, the shaping protrusion 31 matches the shape of the shaping concave portion 111. The second mold 30 can move between a reset position and a processing position along a first direction D1 relative to the first mold 10 under the action of a driving mechanism (not shown) or the like. The processing position is as shown in FIG. Figure 1 As shown. In this position, the shaping convex part 31 of the second mold 30 can enter the shaping concave part 111 to form a concave-convex fit. In this way, when the metal plate is fixed on the first mold 10 by the pressing plate 20, the part of the metal plate corresponding to the shaping concave part 111 is pressed into the shaping concave part 111 by the shaping convex part 31, undergoing plastic deformation, thereby forming a predetermined corrugation on the metal plate. Fig. 9 In this position, the second die 30 is away from the first die 10, and the shaping protrusion 31 is moved out of the shaping concave portion 111, thereby allowing operations such as removing the processed corrugated plate and placing a new metal plate to be processed to be performed.

[0038] Preferably, in order to facilitate the positioning between the first mold 10 and the second mold 30 and guide the relative movement of the two along the first direction D1, the processing device is provided with an additional guide mechanism. Specifically, the first mold 10 is provided with a first guide hole 115, and the second mold 30 is provided with a guide column 32. In the process of the second mold 30 moving toward the processing position, the guide column 32 is inserted into the first guide hole 115 to achieve guided positioning. Of course, the guide column can also be provided on the first mold 10, and the first guide hole can be provided on the second mold 30, or the guide column and the first guide hole that correspond to each other can be provided on both. In other alternative embodiments, the additional guide mechanism can also include other feasible guide forms such as a combination of a guide slider and a guide slot.

[0039] Traditional processing devices are usually provided with a plurality of movable parts with cavities, and these movable parts can be moved closer or farther in linkage with the processing operation. When moving closer, the cavities of these movable parts are spliced ​​to form a shaping recess. According to the solution of the present invention, the shaping recess 111 is provided on a one-piece component. For example, the first mold 10 includes a base component 11 constructed as a one-piece component, and the shaping recess 111 is constructed as a groove on the base component 11. Compared with traditional processing devices, the solution of the present invention is obviously simpler. In particular, most of the movable parts and the corresponding driving or linkage mechanisms are eliminated, which can greatly reduce the possibility that the movable parts of the processing device are difficult to move into place due to failures, and the yield and reliability of the processing operation can be improved. Such a setting can also reduce the production cost for the processing device itself and reduce the difficulty of maintenance during use.

[0040] The reason why the traditional processing device is provided with a complex driving or linkage mechanism and forms a shaping concave portion by splicing is to make the metal plate have a roughly uniform thickness and avoid it being excessively thinned at a certain place due to pressure during the corrugation forming process. In contrast, the scheme of the present invention adopts a different setting to achieve this purpose. According to the present invention, the pressing plate 20 is attached to the first mold 10 in a removable manner. In some embodiments, the base member 11 of the first mold 10 is provided with a fixing hole 116, and the pressing plate 20 is provided with a through hole 22. After the pressing plate 20 is installed in place, the fasteners such as bolts and pins can be used to pass through the through hole 22 and connect in the fixing hole 116 to attach the pressing plate 20 to the base member 11. In other words, the pressing plate 20 is also a substantially fixed component during the processing after the metal plate is installed in place. Therefore, the complex driving or linkage mechanism set for the pressing plate in the traditional processing device can be omitted, further simplifying the structure and promoting the realization of the above-mentioned technical effects.

[0041] Among them, the pressing plate 20 limits the metal plate along the first direction D1 to prevent it from moving relative to the first mold 10, but allows the metal plate to move relative to the first mold 10 in a plane perpendicular to the first direction D1. In this way, during the processing, as the metal plate is pressed into the shaping recess 111 by the shaping protrusion 31, the parts of the metal plate located on both sides of the shaping recess 111 are pulled close to each other, thereby avoiding excessive thinning caused by excessive extension of the part of the metal plate pressed into the shaping recess 111. This clamping and fixing effect of the pressing plate 20 on the metal plate can be achieved by adjusting the fastening force of the fastener. In some embodiments, the surfaces that contact each other, such as the surface of the metal plate, the surface of the pressing plate 20, and the surface of the first mold 10, can also be subjected to friction reduction treatment. For example, a coating operation can be performed on at least one surface, and the friction coefficient of the coated film is less than the friction coefficient of at least one of the surfaces. Or lubricating grease can also be applied to these surfaces.

[0042] In some embodiments, the processing device according to the present invention is specifically used to process the metal plate that has been prefabricated to form the first corrugation 202 to form the second corrugation 203. In view of this, preferably, the base member 11 of the first mold 10 is also provided with an avoidance recess 112, which is roughly constructed as a full-length groove perpendicular to the shaping recess 111 and has a cross-sectional profile roughly the same as the first corrugation 202. When the metal plate is clamped and fixed between the pressing plate 20 and the first mold 10, the first corrugation 202 is accommodated in the avoidance recess 112, so as to maintain the integrity of the processed first corrugation 202 during the processing and avoid its damage and deformation. Preferably, the pressing plate 20 is provided with a fixed protrusion 21, which is constructed as a full-length protrusion and has a cross-sectional profile roughly the same as the first corrugation 202. Therefore, the fixed protrusion 21 matches the shape of the avoidance recess 112. When the metal plate is clamped and fixed between the pressing plate 20 and the first die 10 , the fixing protrusion 21 extends into the inner side of the first corrugation 202 and cooperates with the avoiding recess 112 to clamp and fix the first corrugation 202 along the first direction D1 .

[0043] refer to Figures 5 to 7 , the processing device 1 according to the present invention also includes an auxiliary shaping member 40, which has an auxiliary shaping protrusion 41, which is used to process the flower knot feature at the intersection 204 of the first corrugation 202 and the second corrugation 203. Among them, the auxiliary shaping member 40 is arranged on the side of the first mold 10 away from the second mold 30. For example, the auxiliary shaping member 40 can be located below the first mold 10. The base part 11 of the first mold 10 is provided with a through cavity 114 that penetrates to the shaping recess 111. It can be understood that since the first corrugation 202 and the second corrugation 203 both protrude from the metal plate body 201, and the protruding height of the first corrugation 202 is greater than the protruding height of the second corrugation 203, the through cavity 114 also penetrates to the avoidance recess 112 at the same time.

[0044] The auxiliary shaping member 40 can move relative to the first mold 10 along the first direction D1 between the second reset position and the second processing position under the action of a driving mechanism (not shown) or the like. Figure 1 In this position, the auxiliary shaping protrusion 41 of the auxiliary shaping member 40 can enter the through cavity 114 and squeeze the first corrugation 202 at the intersection 204 to form a predetermined rosette feature. Preferably, the operation of the auxiliary shaping protrusion 41 squeezing the first corrugation 202 can be performed simultaneously with the operation of the shaping protrusion 31 squeezing the metal plate to form the second corrugation 203. The second reset position is as shown in FIG. Fig. 9As shown. In this position, the auxiliary shaping member 40 is away from the first mold 10, so as to allow operations such as removing the processed corrugated plate and placing a new metal plate to be processed. Preferably, a limit frame 12 is provided on the lower side of the base member 11 for pre-installing the auxiliary shaping member 40 before the processing operation. The internal space of the limit frame 12 forms a part of the through cavity 114. The limit frame 12 can be a member integrally formed with the base member 11, or it can be made separately and fixedly connected to the base member 11.

[0045] like Figure 5 and Figure 6 As shown, the auxiliary shaping protrusion 41 has a contour shape that tapers toward the metal plate in a cross section perpendicular to the second corrugation direction D3, and its end in contact with the metal plate is configured as an arc surface, which can be extended to the main body of the auxiliary shaping member 40 with a wider cross section by inclined planes or arc surfaces or a combination of the two on both sides. Among them, along the second corrugation direction D3, the auxiliary shaping protrusion 41 has a uniform cross section. Therefore, the auxiliary shaping protrusion 41 squeezes the first corrugation 202 as a whole, forming a notch at the squeezed position. Alternatively, as Figure 8 As shown, the alternative auxiliary shaping protrusion 51 of the alternative auxiliary shaping member 50 according to another embodiment has a notch 52 at a position corresponding to the crest of the first corrugation 202. During extrusion, the notch 52 avoids the crest of the first corrugation 202, and the two end points of the notch 52 squeeze the first corrugation 202 on both sides of the crest, so that two pits are formed on both sides of the crest of the first corrugation 202.

[0046] In addition, in some embodiments, the shaping protrusion 31 of the second mold 30 is provided with a tongue (not shown) at a position corresponding to the intersection 204 of the corrugated plate 200 in the middle along the length direction. The tongue elastically protrudes outward along the first direction D1 relative to other parts of the shaping protrusion 31 under the elastic force of the elastic member. During the processing, the tongue can form a peak structure at the intersection, and the protruding height of the peak structure relative to the metal plate body 201 is greater than the protruding height of the second corrugation 203 and greater than the protruding height of the first corrugation 202. By providing an elastic member, the tongue can always keep in contact with the metal plate to provide an extrusion force, and the extrusion force is substantially equal to the elastic force. This can prevent the tongue from applying excessive force to the metal plate and breaking the metal plate during the formation of the peak structure.

[0047] Preferably, the processing device 1 includes two auxiliary shaping members 40, which are arranged on both sides of the shaping recess 111 along the first corrugation direction D2 to process the first corrugation 202 on both sides of the second corrugation 203. The two auxiliary shaping members 40 are mounted on the auxiliary shaping frame 42 to form an integrated structure for synchronous movement.

[0048] In order to guide the auxiliary shaping member 40 to move between the second reset position and the second processing position, the processing device is further provided with an additional guiding mechanism. Figures 4 to 7 As shown, the outer side of the auxiliary shaping frame is provided with a first guide half groove 421, and the inner side of the limit frame 12 is provided with a second guide half groove 121. The first guide half groove 421 and the second guide half groove 121 both have an arc-shaped cross-sectional profile, and the two are combined into a guide groove when the auxiliary shaping member 40 is installed in the limit frame 12. In addition, the guide pin 47 is inserted into the guide groove to guide the auxiliary shaping member 40 to move along the axial direction defined by the guide column. The axial direction is roughly parallel to the first direction D1. Of course, in alternative embodiments, the additional guide mechanism can also include other feasible specific guide methods such as a combination of a guide rail and a guide groove alone or simultaneously.

[0049] Further preferably, the distance between the two auxiliary shaping members 40 is linked to the position of the auxiliary shaping member 40, that is, the distance between the two auxiliary shaping members 40 is adjustable. Specifically, when the auxiliary shaping member 40 is located at the second reset position, the distance between the two auxiliary shaping members 40 is far, and when the auxiliary shaping member 40 is located at the second processing position, the distance between the two auxiliary shaping members 40 is close. Preferably, the adjustment of the distance between the auxiliary shaping members 40 is achieved by the first guide mechanism 43. For example, the first guide mechanism 43 may include a guide shaft mounted on the auxiliary shaping frame 42. Accordingly, the auxiliary shaping member 40 is provided with a second guide hole 44. The guide shaft extends substantially parallel to the first corrugation direction D2 and passes through the second guide hole 44. Preferably, the auxiliary shaping member 40 is provided with an oil dripping hole 46, which is connected to the second guide hole 44. Lubricating material can be applied between the second guide hole 44 and the guide shaft through the oil dripping hole 46. It is understood that, in addition to the guide shaft, the first guide mechanism 43 may also include other feasible specific guide modes such as a combination of a guide rail and a guide slot, either alone or simultaneously. In addition, the guide shaft, guide column, guide pin and other components referred to herein differ only in relative size, and there is no obvious difference in their guiding function. When the size is ignored, it can be understood that the three refer to the same type of components.

[0050] Furthermore, the limiting frame 12 and the auxiliary shaping member 40 are respectively provided with cam surfaces that cooperate with each other. Figure 5 and Figure 7As shown, a first wedge block 45 is provided on the side of the auxiliary shaping member 40, and the first wedge block 45 has a first cam surface 451 formed by an inclined surface. A second wedge block 122 corresponding to the first wedge block 45 is provided at a corresponding position on the inner side of the limiting frame 12, and the second wedge block 122 has a second cam surface 123 formed by an inclined surface. It can be understood that the inclined surface here refers to the cam surface being inclined relative to the main movement direction (i.e., the first direction D1) of the auxiliary shaping member 40, and the inclination directions of the cam surfaces corresponding to the two auxiliary shaping members 40 are opposite. Fig. 10A At the second reset position, the two auxiliary shaping members 40 are separated by a first distance L1 (calculated from the outer sides that are the farthest apart from each other). As the auxiliary shaping members 40 move toward the second processing position, until the first cam surface 451 and the second cam surface 123 contact each other, the two auxiliary shaping members 40 always maintain the first distance L1 ( Fig. 10B ). Further, as the first cam surface 451 and the second cam surface 123 begin to contact, the inclined setting of the cam surface forces the two auxiliary shaping components 40 to translate toward the middle along the guide axis, and the distance between the two begins to decrease. Until the second processing position, the distance between the two becomes the minimum, and the distance is the second distance L2. In this way, the automatic adjustment of the distance between the auxiliary shaping components 40 is achieved through the cooperation of the cam surfaces.

[0051] Preferably, the auxiliary shaping member 40 is also provided with a corresponding traction device, which is used to reset the distance between the two to the larger first distance L1 after the auxiliary shaping member 40 returns to the second reset position. In some embodiments, the traction device can be an elastic member such as a spring. Specifically, a spring that is stretched after the cam surface begins to match and thus applies a tensile force to the auxiliary shaping member 40 can be set between each auxiliary shaping member 40 and the auxiliary shaping frame 42, or a spring that is compressed after the cam surface begins to match and thus applies a compression rebound force to the auxiliary shaping member 40 can be set between the two auxiliary shaping members 40, or different springs can be set at the same time to apply a tensile force and a compression rebound force respectively. Other embodiments of the traction device can also be other feasible drive mechanisms such as a hydraulic cylinder, a ball screw, a pneumatic device, an electric motor, etc.

[0052] In the above-described embodiment, the distance reduction between the auxiliary shaping members 40 is achieved by the cam surface, and the distance increase and reset is achieved by the traction device. However, it can be understood that in alternative embodiments, the distance reduction can also be achieved by the traction device and the distance increase and reset can be achieved by the cam surface, or the distance reduction and distance increase and reset can be achieved by two sets of cam surfaces, or the distance reduction and distance increase and reset can be achieved by the traction device, or the distance reduction and distance increase and reset can be achieved by the traction device, or the cam surface and the traction device can be combined to achieve.

It is not intended that the present invention be exclusive or limited to a single disclosed embodiment. As above, a person of ordinary skill in the field of the above teachings will understand the various substitutions and variations of the present invention.
