[0045] In order to keep the following description of the embodiments of the present application clear and brief, the present application omits the detailed description of known functions and known components.

[0046] The embodiment of the present application provides a die set for manufacturing corrugated plates, as shown in Figure 1, which mainly comprises a supporting base 1, a first stamping assembly 2 and a second stamping assembly 3.

[0047] The supporting base 1 comprises a supporting bottom plate 10 and a plurality of supporting tables 11 for collectively supporting a plate on the supporting bottom plate 10, and the plurality of supporting tables 11 collectively define a stamping channel 12.

[0048] The first stamping assembly 2 is located above the supporting base 1, and the first stamping assembly 2 comprises a mounting plate 20 and a stamping punch 21 and a blanking component 22 arranged on the mounting plate 20.

[0049] The first stamping assembly 2 can move in a vertical direction relative to the supporting base 1 so that the stamping punch 21 extends into or moves out of the stamping channel 12, and the blanking component 22 abuts against or separates from the supporting tables 11.

[0050] The second stamping assembly 3 is located in the stamping channel 12. The second stamping assembly 3 comprises a guide base assembly 31, a blanking die assembly 32 and an extrusion driving component.

[0051] The guide base assembly 31 is fixed on the supporting bottom plate 10, and the blanking die assembly 32 is slidingly arranged on the guide base assembly 31 and can move in a vertical direction relative to the guide base assembly 31.

[0052] The extrusion driving component is in transmission connection with the blanking die assembly 32 and is used for driving the blanking die assembly 32 to move in a vertical direction relative to the guide base assembly 31.

[0053] Before the die set is used, the metal plate to be stamped is placed on the plurality of supporting tables 11 of the supporting base 1, the first stamping assembly 2 is first controlled to move downward in a vertical direction, and as the stamping punch 21 extends into the stamping channel 12, corresponding convex corrugated segments are formed on the metal plate, and in the process that the first stamping assembly 2 moves downward, the blanking component 22 abuts against the plate placed on the supporting tables 11, so that the edges of the plate are prevented from being raised.

[0054] When the first stamping assembly 2 completes the stamping work, the blanking die assembly 32 of the second stamping assembly 3 is controlled to move upward, and the convex corrugated segments stamped on the plate are stamped by the blanking die assembly 32, so that corresponding blanking ribs 72 and the like are formed on the convex corrugated segments.

[0055] Finally, the blanking die assembly 32 of the second stamping assembly 3 is controlled to move downward to an initial position, the first stamping assembly 2 is controlled to move upward to an initial position, and then the stamped corrugated plate can be taken out.

[0056] The mold set for manufacturing the corrugated plate of the present application can place the metal plate to be punched on the plurality of support tables 11, move the first punching assembly 2 in the vertical direction to punch the metal plate downward, and then move the second punching assembly 3 in the punching channel 12 to punch the metal plate upward. When the mold set is used to manufacture the corrugated plate 7 of the LNG storage tank, all the forming processes can be completed in one station, and the production efficiency of the corrugated plate 7 is greatly improved.

[0057] As shown in FIG. 2, in some embodiments, the punching channel 12 includes a middle forming channel 121 and a plurality of arch pressing channels 120 respectively communicating with the middle forming channel 121. The plurality of arch pressing channels 120 are distributed around the middle forming channel 121 and radially.

[0058] The plurality of support tables 11 on the support seat 1 are annularly distributed, and the plurality of support tables 11 jointly enclose the middle forming channel 121, and the adjacent two support tables 11 are spaced apart to form the arch pressing channel 120.

[0059] Further, the punching punch 21 on the first punching assembly 2 includes a middle forming punch 210 and a plurality of arch pressing punches 211, as shown in FIG. 7.

[0060] The middle forming punch 210 corresponds to the middle forming channel 121, and the plurality of arch pressing punches 211 correspond to the plurality of arch pressing channels 120. That is, when the first punching assembly 2 moves downward, the middle forming punch 210 extends into the middle forming channel 121, and each arch pressing punch 211 extends into one arch pressing channel 120.

[0061] In the present embodiment, the height of the middle forming punch 210 in the direction perpendicular to the mounting plate 20 is greater than the height of the arch pressing punch 211 in the direction perpendicular to the mounting plate 20. That is, the middle forming punch 210 is preferentially in contact with the metal plate on the support table 11 than the arch pressing punch 211.

[0062] Preferably, the free end of the middle forming punch 210 in the present embodiment is spherical, the lower end of the arch pressing punch 211 is outwardly arched, the side end face of the middle forming punch 210 is provided with a chamfer, and an inwardly recessed pit is arranged at the inner region of the lower end of the arch pressing punch 211. The pit cooperates with the upper cylindrical body of the edge pressing punch 321.

[0063] When the first punching assembly 2 moves downward, the middle forming punch 210 punches out the middle corrugated section 70 on the metal plate, and the arch pressing punch 211 punches out the radial corrugated section 71 on the metal plate, as shown in FIG. 9. The middle forming punch 210 and the arch pressing punch 211 on the first punching assembly 1 in the present embodiment simultaneously perform the punching process, the middle shape is regular, and the transition is smooth, so that the corrugated plate 7 formed by punching has a certain anti-deformation ability.

[0064] It should be noted that the pressing arch punch 211 in the utility model is preferably four, and the pressing arch punch 211 and the middle forming punch 210 form a cross-shaped structure. Of course, the specific number of the pressing arch punch 211 is not limited to four, and can be determined according to the shape of the corrugated plate 7 of the LNG storage tank.

[0065] As shown in FIGS. 5 and 6, the edge pressing component 22 of the embodiment mainly comprises a connecting guide plate 221, a pressing plate block 224, an elastic member 223 and a guide column 222.

[0066] The connecting guide plate 221 is fixedly connected with the mounting plate 20 and located on the side of the mounting plate 20 facing the support table 11.

[0067] The pressing plate block 224 is located between the connecting guide plate 221 and the support table 11, and the side of the pressing plate block 224 facing the support table 11 is parallel to the surface of the support table 11. The shape of the pressing plate block 224 is matched with the shape of the support table 11.

[0068] The elastic member 223 is arranged between the connecting guide plate 221 and the pressing plate block 224. One end of the elastic member 223 is fixed on the connecting guide plate 221, and the other end abuts against the pressing plate block 224. When the pressing plate block 224 moves upward to approach the connecting guide plate 221, the elastic member 223 is compressed.

[0069] The elastic member 223 of the embodiment is preferably a nitrogen spring. The fixed end of the nitrogen spring is fixed on the connecting guide plate 221, and the telescopic end abuts against the pressing plate block 224. When the first stamping assembly 2 does not move downward or the pressing plate block 224 does not contact the metal plate piece on the support table 11, the elastic member 223 always exerts an elastic downward force on the pressing plate block 224.

[0070] The guide column 222 is vertically arranged and used for connecting the connecting guide plate 221 and the pressing plate block 224. The guide column 222 is mainly used for guiding the movement of the pressing plate block 224.

[0071] When the first stamping assembly 2 moves downward to stamp the metal plate piece, the pressing block 224 on the edge pressing component 22 first contacts the metal plate piece located in the region of the support table 11. With the gradual downward movement of the first stamping assembly 2, the stamping punch 21 also extends into the stamping channel 12, and then the connecting guide plate 221 moves downward along the guide column 222 to gradually approach the pressing block 224 and press the elastic member 223, thereby increasing the pressure applied to the metal plate piece to ensure the overall stability of the plate piece during the stamping process.

[0072] The number of the edge pressing component 22 of the embodiment can be equal to or less than the number of the support tables 11 on the support seat 1. Each edge pressing component 22 corresponds to one support table 11.

[0073] In some embodiments, the plurality of edge pressing components 22 in the first stamping assembly 2 are arranged around the periphery of the mounting plate 20. The edge pressing component 22 further comprises a plurality of linking plates 220, and each edge pressing component 22 corresponds to at least two linking plates 220.

[0074] The linking plates 220 are respectively bolted to the side wall surface of the mounting plate 20 and the side wall surface of the connecting guide plate 221, so that each edge pressing component 22 is fixed to the mounting plate 20. This structure facilitates the installation and disassembly of the edge pressing component 22.

[0075] Each connecting guide plate 221 is suspended on the mounting plate 20 by two linking plates 220, and this structure is simple and facilitates the installation of the edge pressing component 22.

[0076] In some embodiments, a plurality of guide columns 222 are arranged between the connecting guide plate 221 and the edge pressing block 224, a plurality of through holes for the guide columns 222 to pass through are arranged on the connecting guide plate 221, and a threaded hole for the end of the guide column 222 to connect is arranged on the edge pressing block 224. The guide column 222 passes through the through hole on the connecting guide plate 221 and extends into the threaded hole on the edge pressing block 224 to be screwed with the edge pressing block 224.

[0077] Preferably, the top end of the guide column 222 has a circular truncated cone with an outer diameter greater than the diameter of the through hole on the connecting guide plate 221, and under the action of the elastic member 223, the circular truncated cone at the top end of the guide column 222 abuts against the connecting guide plate 221.

[0078] The connecting guide plate 221 and the mounting plate 20 in the embodiment have a certain distance in the vertical direction to ensure that when the first stamping assembly 2 completes the stamping work on the metal plate piece, the circular truncated cone at the top end of the guide column 222 will not contact the mounting plate 20.

[0079] Preferably, the number of guide columns 222 and the number of elastic members 223 in the embodiment are three or more, and the three guide columns 222 coincide with the three elastic members 223 at the center of the triangle formed by the connecting guide plate 221.

[0080] As shown in FIGS. 3 and 4, the middle region of each edge pressing block 224 in the first stamping assembly 2 is provided with a chamfer 225.

[0081] As shown in FIGS. 3 and 4, in some embodiments, the guide seat assembly 31 in the second stamping assembly 3 comprises a first guide seat 310 and a second guide seat 311, and each of the two guide seats is provided with a vertical guide rail 315.

[0082] The blank holder die assembly 32 comprises a blank holder female die 320 and a blank holder male die 321. The blank holder female die 320 is arranged on the vertical guide rail 315 of the first guide base 310, and the blank holder male die 321 is arranged on the vertical guide rail 315 of the second guide base 311. The blank holder female die 320 and the blank holder male die 321 are respectively capable of moving up and down along the vertical guide rail 315.

[0083] Further, the extrusion driving component of the embodiment comprises a transmission assembly and a hydraulic element 38. The transmission assembly comprises a transmission frame and a first sliding block 33 and a second sliding block 34 arranged on the transmission frame. The first sliding block 33 and the second sliding block 34 are respectively capable of moving synchronously with the transmission frame. The first sliding block 33 corresponds to the blank holder female die 320, and the second sliding block 34 corresponds to the blank holder male die 321.

[0084] The hydraulic element 38 is connected with the transmission frame, for driving the transmission frame to move in the transverse direction, and when the transmission frame moves, the blank holder female die 320 is pushed to move upward by the first sliding block 33, and the blank holder male die 321 is pushed to move upward by the second sliding block 34.

[0085] As shown in FIG. 3, the top end of the blank holder female die 320 is provided with a groove for supporting the upper corrugated segment of the metal plate or is in the shape of a downward arch-shaped notch, and the top end of the blank holder male die 321 is provided with a cylinder. When the blank holder female die 320 and the blank holder male die 321 respectively move upward, the blank holder groove can support the upper corrugated segment of the metal plate, and the blank holder male die 321 forms a blank holder rib 72 on the corrugated segment of the metal plate through the cylinder thereon. The blank holder rib 72 pressed by the blank holder male die 321 can reduce the irregularity of the corrugated segment to some extent, and also enhances the energy absorption of the corrugated segment.

[0086] In order to realize that the sliding blocks can push the blank holder female die 320 and the blank holder male die 321 to move upward, as shown in FIG. 3 and FIG. 4, in some embodiments, the first sliding block 33 and the blank holder female die 320 and the second sliding block 34 and the blank holder male die 321 are respectively matched by a pair of corresponding inclined surfaces.

[0087] Taking the first sliding block 33 and the blank holder female die 320 as an example, when the inclined surface of the first sliding block 33 is attached to the inclined surface of the blank holder female die 320, as the first sliding block 33 continues to move in the transverse direction, the first sliding block 33 applies an upward driving force to the blank holder female die 320 through the matched inclined surfaces, so that the blank holder female die 320 moves upward relative to the first guide base 310. When the first sliding block 33 moves in the opposite direction, the blank holder female die 320 moves downward along the vertical guide rail 315 under the action of gravity.

[0088] As shown in FIG. 3, in some embodiments, the first guide seat 310 and the second guide seat 311 are arranged side by side in the arch pressing channel 120, and the relative positions of the two guide seats are not specifically limited. The second guide seat 311 is closer to the middle forming channel 121 than the first guide seat 310, or the first guide seat 310 is closer to the middle forming channel 121 than the second guide seat 311.

[0089] The transmission frame in the transmission assembly includes a push plate 36 and a first side plate 35 and a second side plate 39 connected with the push plate 36 respectively. The first side plate 35 is located at the first side of the two guide seats, and the second side plate 39 is located at the second side of the two guide seats. That is, the first sliding block 33 and the second sliding block 34 are respectively located between the first side plate 35 and the second side plate 39 and are connected with the two side plates. The first sliding block 33 is located at the side of the first guide seat 310 facing the middle forming channel 121, and the second sliding block 34 is located at the side of the second guide seat 311 facing the middle forming channel 121. The transmission frame structure can surround the two guide seats, ensuring the compactness of the extrusion driving component structure.

[0090] The first side plate 35 and the second side plate 39 of the embodiment are both long strip plates, and the connection mode of the two side plates with the two sliding blocks is not specifically limited. For example, the first side plate 35 and the second side plate 39 are respectively provided with two through holes, and the first sliding block 33 and the second sliding block 34 are provided with a through channel, and the two side plates and the two sliding blocks can be connected by sequentially passing through the through hole of one of the side plates, the through channel of the sliding block and the through hole of the other side plate through the positioning pin 322.

[0091] The hydraulic element 38 of the embodiment can be a double-acting piston hydraulic cylinder, which is fixed on the edge of the support bottom plate 10 through the mounting block 37. The telescopic part of the hydraulic element 38 is connected with the push plate 36 through the through hole of the mounting block 37, and the telescopic movement of the telescopic part drives the movement of the transmission frame.

[0092] As shown in FIG. 3 and FIG. 4, in some embodiments, the first guide seat 310 and the second guide seat 311 respectively include a seat body bottom plate 314, a seat body vertical plate 312 and two seat body side plates 313.

[0093] The seat body bottom plate 314 can be fixed on the support bottom plate 10 by bolt connection, the two seat body side plates 313 are connected with the opposite ends of the seat body bottom plate 314, and the seat body vertical plate 312 is connected with the two seat body side plates 313 respectively. The vertical guide rail 315 is arranged on the side of the seat body vertical plate 312 away from the two seat body side plates 313, and the edge pressing concave die 320 and the edge pressing convex die 321 are respectively arranged to slide on the vertical guide rail 315 of the seat body vertical plate 312. The two seat body side plates 313, the seat body vertical plate 312 and the seat body bottom plate 314 form a recess 316.

[0094] Further, the seat body vertical plate 312 and the seat body bottom plate 314 are spaced apart to form a gap for the first slider 33 or the second slider 34 to pass through. When the first slider 33 pushes the edge pressing concave die 320 to move upward, a part on the first slider 33 can pass through the gap on the seat body vertical plate 312 and extend into the cavity 316. The same applies to the first slider 34.

[0095] As shown in FIG. 3, in some embodiments, the inclined surface on the first slider 33 is always in contact with the inclined surface on the edge pressing concave die 320, while the second slider 34 needs to move to fit the inclined surface on the edge pressing convex die 321. That is, when the hydraulic element 38 drives the transmission frame to start moving, the first slider 33 pushes the edge pressing concave die 320 to start moving upward, and the second slider 34 pushes the edge pressing convex die 321 to move upward after the transmission frame moves a certain distance.

[0096] In some embodiments, the die set further comprises a material guiding assembly. As shown in FIG. 1, the material guiding assembly comprises a material guiding plate 4 and a material blocking pin 5, which are fixed on the support table 11 and together enclose a plate resting area with at least one open side. The cooperation of the material guiding plate 4 and the material blocking pin 5 can ensure that the metal plate does not deviate during stamping.

[0097] The material guiding plate 4 of the present embodiment is a long strip plate, and there are two of them. One of the material guiding plates 4 is fixed on two adjacent support tables 11, and the other material guiding plate 4 is fixed on another two adjacent support tables 11. The material guiding plate 4 and the support table 11 are respectively provided with opposite threaded holes, and the material guiding plate 4 can be fixed on the support table 11 by bolts.

[0098] Further, the number of material blocking pins 5 is two, and the two material blocking pins 5 are located between the two material guiding plates 4 and enclose a rectangular plate resting area with the two material guiding plates 4. The two material blocking pins 5 and the two material guiding plates 4 are respectively fixed on the edges of the support table 11, thereby ensuring the maximization of the area of the plate resting area.

[0099] In some embodiments, the die set further comprises a lifting control system and a sensing device 6, and the sensing device 6 is electrically connected with the lifting control system. The lifting control system is connected with the first stamping assembly 2 for controlling the first stamping assembly 2 to move in the vertical direction. For example, the lifting control system is connected with the mounting plate 20 of the first stamping assembly 2.

[0100] The sensing device 6 is arranged on the support table 11, and generates a stop descending signal when the middle forming convex die 210 or the arch pressing convex die 211 moves downward to a preset position. The lifting control system can receive the stop descending signal generated by the sensing device 6 to control the first stamping assembly 2 to stop moving downward, thereby realizing automatic control.

[0101] The lifting control system of the embodiment can use conventional lifting mechanisms, and the specific structure will not be described here.

[0102] As shown in FIG. 1, in some embodiments, the sensing device 6 is fixed on the side wall surface of two adjacent support tables 11. As shown in FIG. 8, the sensing device 6 includes a fixed plate 61 connected with the outer peripheral surface of the two support tables 11 respectively and a sensor 60 arranged on the fixed plate 61, wherein the sensor 60 is an infrared shielding sensor.

[0103] The sensor 60 sends an infrared signal to the pressure arch channel 120, and when the pressure arch punch 211 extends into the pressure arch channel 120, the infrared signal is reflected back through the pressure arch punch 211, at which time it can be judged that the pressure arch punch 211 moves downward to the designated position. At this time, the downward movement of the first stamping assembly 2 can be stopped. The specific working principle of the sensor 60 belongs to the prior art and will not be described here.

[0104] The specific working process of the mold set for manufacturing the corrugated plate of the embodiment will be described in detail below:

[0105] First, the first stamping assembly 2 is controlled to move downward, and after the pressure arch punch 211 and the middle forming punch 210 move downward to the predetermined position, the sensor 60 in the sensing device 6 receives the signal, at which time the first stamping assembly 2 no longer continues to move downward.

[0106] Then, the hydraulic element 38 in the second stamping assembly 3 starts to work, driving the push plate 36 to move outward, and then driving the first slider 33 and the second slider 34 to move outward through the transmission frame. Since the first slider 33 and the pressure edge recess 320 first contact, the pressure edge recess 320 first moves upward, and when the pressure edge recess 320 supports the metal plate piece, the second slider 34 pushes the pressure edge punch 321 to move upward to the designated position, completing the pressing work. At this time, the first slider 33 and the second slider 34 are driven to move inward by the hydraulic element 38, and the pressure edge recess 320 and the pressure edge punch 321 move downward to the initial position due to the action of gravity.

[0107] Finally, the first stamping assembly 2 is controlled to move upward, at which time the energy storage of the elastic element 223 in the pressure edge component 22 is released to complete the unloading work, and thus the stamping work is completed.

[0108] The above description is intended to be illustrative and not restrictive, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more aspects thereof) can be used in combination with each other, and the embodiments can be combined with each other in various combinations or arrangements.
