Description

Technical Field

[0002] Traditional automobile tailgate load-bearing platforms achieve their load-bearing capacity and stability requirements by using high-strength steel, bending, splicing, welding, and crisscrossing horizontal and vertical ribs. This process involves bending the steel plate into the required angle and shape through a bending machine to form the basic structure of the load-bearing platform.

[0003] Traditional automobile tail panels include center ribs, side ribs, oblique ribs and front tongues. Each type of panel needs to be manufactured by designated equipment, and then spliced ​​and welded into a complete platform structure with load-bearing capacity. At present, the forming equipment for each panel is relatively scattered, and there is no way to form an assembly line for batch production. Each panel is processed separately on different equipment for corresponding parts, and then manually docked with each equipment for loading and unloading. When it comes to the processing of the same parts, many equipment are universal, but due to the different specifications of each panel, the processing position of the equipment needs to be repeatedly adjusted, and the operation is very complicated. When processing each panel, the assembly line equipment is messy and complicated, and the center ribs, side ribs, oblique ribs and front tongues cannot be processed at the same time.

The guide holes 2212 cooperate with the guide pillars 2222 to play a guiding role (such as Figure 5 In the initial state, the upper die seat 2211 is driven by the die assembly 224 to rise, leaving a gap 223 between the upper die seat 2211 and the lower die seat 2221 (such as Figure 5 ), the gap 223 is for the plate reinforcement member 15 to be transported through.

[0089] The lower die base 2221 includes a first die cavity 2223 and a die element 2224 (such as a Figure 6 ), the die 2224 can move up and down vertically, and the upper die base 2211 includes a second die cavity 2213 and a rib pressing module 2214 (such as Figure 8 ), the rib pressing module 2214 can move up and down in the vertical direction, and the first die cavity 2223 and the second die cavity 2213 are correspondingly arranged. When the first reinforcing rib 111 of the plate rib part 15 is pressed, the die 2224 moves upward and extends out of the first die cavity 2223, and continues to press the plate rib part 15 upward. The rib part of the plate rib part 15 bulges under the pressing of the die 2224. The die 2224 presses the plate rib part 15 to bulge into the second die cavity 2213. The second die cavity 2213 provides space for the rib part to bulge and deform. Under the upward pressing of the die 2224, the rib pressing module 2214 shrinks inward along the second die cavity 2213 to make way for the bulge of the rib part. The structure of the first reinforcing rib 111 of the plate rib part 15 after rib pressing is as shown in FIG. Figure 2 .

[0090] The lower die 222 includes a die drive assembly 226 (eg, Figure 7), the die driving assembly 226 is connected to the die piece 2224 via a first reversing member 227, the die driving assembly 226 moves horizontally, and drives the die piece 2224 to move vertically via the first reversing member 227, so as to press the first reinforcing rib 111. The die driving assembly 226 includes a telescopic gas rod 2261 and a moving block 2262 connected to the telescopic gas rod 2261. In an initial state, the die piece 2224 is placed in the first die cavity 2223. When the first reinforcing rib 111 is pressed, the die piece 2224 protrudes upward from the first die cavity 2223 under the drive of the die driving assembly 226, and the protruding height is the depth of the first reinforcing rib 111.

[0091] The upper mold 221 includes a demolding mechanism, which is used to demold the first reinforcing rib 111 protruding into the second die cavity 2213. The demolding mechanism includes a die plate 2215 and a demolding assembly 2216. The die plate 2215 is connected to the die assembly 224. The die assembly 224 drives the die plate 2215 to move up and down. The die plate 2215 is connected to the upper mold base 2211. The movement of the die plate 2215 causes the upper mold base 2211 to move vertically up and down to achieve molding and demolding. The demolding assembly 2216 is arranged between the second die cavity 2213 and the rib pressing module 2214 (such as Fig. 9 ), during pressing, the rib pressing module 2214 squeezes the demolding assembly 2216 under the top action of the die 2224 to retract toward the second die cavity 2213, and the rib pressing module 2214 is initially flush with the die surface of the upper die seat 2211 under the action of the demolding assembly 2216 (such as Figure 8 ), when the rib pressing module 2214 retracts to squeeze the demolding component 2216 to store force, the demolding component 2216 provides the rib pressing module 2214 with an outward thrust toward the second die cavity 2213 for demolding.

[0092] like Fig. 9 A second reversing member 225 is provided between the die assembly 224 and the die plate 2215. The die assembly 224 moves laterally, and the die plate 2215 moves vertically through the second reversing member 225. The die assembly 224 includes a driving oil cylinder 2241 and a pressing plate 2242. The pressing plate 2242 can move laterally under the drive of the driving oil cylinder 2241. The first reversing member 227 and the second reversing member 225 both adopt a reversing setting of inclined surface to inclined surface. The second reversing structure includes a first inclined surface 2251 provided on the pressing plate 2242 and a second inclined surface 2252 provided on the die plate 2215. The first inclined surface 2251 and the second inclined surface 2252 are arranged to be inclined in opposite directions, and the first inclined surface 2251 and the second inclined surface 2252 are movably matched, and the reversing drive is realized through the inclined matching of the two inclined surfaces.

[0093] When the driving cylinder 2241 drives the pressing plate 2242 to move laterally, the first inclined surface 2251 and the second inclined surface 2252 are pressed against each other, and the first inclined surface 2251 moves laterally to press the second inclined surface 2252. Under the action of the inclined surfaces, the pressing plate 2215 moves vertically under the action of the second inclined surface 2252, thereby causing the upper mold base 2211 to move downward.

[0094] like Fig. 9 The demolding assembly 2216 includes an elastic member, which may be a spring. The elastic member is disposed between the rib pressing module 2214 and the die cavity. When the first reinforcing rib 111 is pressed, the rib pressing module 2214 squeezes the elastic member and moves inward toward the die cavity. When the pressing force disappears, the rib pressing module 2214 begins to move outward along the second die cavity 2213 under the elastic force of the elastic member. The elastic force of the elastic member causes the rib pressing module 2214 to pop out instantly, so that the first reinforcing rib 111 is pushed out instantly, thereby achieving precise demolding and improving demolding efficiency.

[0095] When the rib pressing and convex rib device 22 is used, the plate rib member 15 to be pressed is transported to the gap 223 between the upper die seat 2211 and the lower die seat 2221, and the plate rib member 15 to be pressed is placed on the die surface of the lower die seat 2221. The upper die seat 2211 is driven downward by the die assembly 224 and pressed on the plate rib member 15, so that the plate rib member 15 is attached between the die surfaces of the upper die seat 2211 and the lower die seat 2221. In the rib pressing process, the die driving assembly 226 drives the die member 2224 to convex upward along the first die cavity 2223, and the die member 2224 acts on the corresponding part of the plate rib member 15. The die member 2224 pushes the corresponding part of the plate rib member 15 upward to convexly deform toward the second die cavity 2213, thereby forming the first reinforcing rib 111. The die 2224 presses the plate upwards, and cooperates with the rib pressing module 2214 in the second die cavity 2213 to perform plastic pressing of the first reinforcing rib 111. The first reinforcing rib 111 protrudes into the second die cavity 2213. The rib pressing module 2214 compresses the elastic part to shrink under the action of the die 2224, and the elastic part accumulates force. After the pressing is completed, the die is demolded, and the die driving assembly 226 is used to move the die 2224 downward out of the second die cavity 2213. The die assembly 224 is driven to move the upper die seat 2211 upward away from the plate rib part 15. The rib pressing module 2214 pushes the first reinforcing rib 111 out of the second die cavity 2213 under the elastic force of the elastic part, thus achieving demolding.

The push rod 248 is rotated by a rocking wheel 249 to move spirally. The push rod 248 can move in a direction close to or away from the base 245. The end of the push rod 248 is fixed on the base 245. Through the rotation of the rocking wheel 249, the push rod 248 drives the base 245 to move left and right in the slide groove 246 and the slide rail 247. At least two groups of punching notch mechanisms 242 on the left and right sides can relatively adjust the interval width between the two, and the interval width is adapted to the width of the plate reinforcement member 15.

[0099] The roll forming device 25 provided in this embodiment includes a first roller pressing group 251 and a first roller conveying group 252 (such as Figure 3 ), the first roller pressing group 251 is used for rolling the bending of the first folding portion 112 of the plate reinforcement member 15, and the first roller transporting group 252 is used for transporting the plate reinforcement member 15. The first roller pressing group 251 includes two groups of roller assemblies 523 arranged on the left and right sides, which are used for rolling the bending of the first folding portions 112 on the left and right sides of the plate reinforcement member 15. The roller assemblies 523 are arranged at different heights of the rollers and at different angles of inclination of different pressing surfaces. When the rollers are configured to rotate continuously, the rollers press the first folding portion 112 of the plate reinforcement member 15 at corresponding pressure and speed, causing it to bend and deform.

[0100] The roll forming device 25 can adopt an existing roll forming machine which can press the plate reinforcement member 15 into a folded edge through a series of rollers through continuous rolling action, which will not be introduced in detail here.

The plate reinforcement member 15 does not stop being transported, and the plate reinforcement member 15 is cut by the following shearing knife 268 during the transportation process. After the following shearing completes the cutting, the cutting table 263 is reset by the driving of the cutting driving mechanism to perform the next following shearing. In order to facilitate the subsequent front and rear bending of the front and rear folding device 27 , the first flange portion 113 does not interfere with the first folding portion 112 , and the cutting position of the cutter 268 is located in the notch 151 of the first folding portion 112 .

[0106] The folding machine 272 includes a machine table 274, and a third mounting seat 275 is arranged on the left and right sides of the machine table 274. A work surface 276 is arranged in the middle of the machine table 274, and the work surface 276 is used to place the plate rib member 15 to be bent. The folding member 273 is vertically provided with a first pressing plate 2731 and a second pressing plate 2732. The first pressing plate 2731 is used to achieve the bending of the first flange portion 113 of the plate rib member 15, and the second pressing plate 2732 is used to connect the oil cylinder piston rod 277.

[0109] like Fig.16, a guide slope 2734 is provided on the outer side of the first pressing plate 2731 for the introduction or export of the plate reinforcement member 15. A first installation groove 2735 is provided on the inner side of the first pressing plate 2731, and a plurality of pressing blocks 2736 can be detachably installed in the first installation groove 2735.

[0112] Side rib forming production line 3, such as Figure 17-18 .

[0113] The structure of the side rib plate 12 is as follows: Fig.17 The side rib plate forming production line 3 includes pressing of the second reinforcing rib 121, rolling of the second folding portion 122, and bending of the second flange portion 123. The forming of the side rib plate 12 and the middle rib plate 11 lacks the pressing of the logo mold 114, and the other pressing processes are the same.

[0114] Fig.18 A forming production line 3 for side rib plates is provided, which includes a feeding leveling device 21, a rib punching device 22, a notch punching device 24, a roll forming device 25, a shearing device 26, and a front and rear folding device 27, which are sequentially arranged along the conveying direction of the plate rib member 15. Each device is automatically driven by a computer control cabinet and a hydraulic control center to realize the pressing and forming of the side rib plate 12. The feeding leveling device 21, the rib punching device 22, the notch punching device 24, the roll forming device 25, the shearing device 26, and the front and rear folding device 27 are consistent with the device structure and pressing process of the forming production line 2 for the center rib plate.

[0115] The molding production line 4 of the front tongue plate, such as Figure 19-22 .

[0116] The structure of the front tongue plate 13 is as follows Fig.19 , Fig. 20 A front tongue plate 13 forming production line is provided, which includes a feed leveling device 21, a rib pressing device 22, a notch punching device 24, a roller forming device 25, a shearing device 26 and a front and rear folding device 27 which are arranged in sequence along the conveying direction of the plate rib part 15. Each device has a computer control cabinet and a hydraulic control center for automatic drive to realize the press forming of the side rib plate 12.

[0117] Among them, the feeding leveling device 21, the rib punching device 22, the notch punching device 24, the roller forming device 25, the shearing device 26 and the front and rear folding devices 27 are consistent with the device structure and pressing process of the forming production line 2 of the center rib plate. Since the pressing process of the front tongue plate 13 includes the pressing of the irregular reinforcing rib 131, the pressing of the left folding part 132 and the pressing of the front and rear flange parts, the notch punching device 24 and the roller forming device 25 are slightly different from the forming production line 2 of the center rib plate for the pressing of the left folding part 132 of the front tongue plate 13.

[0118] The notch punching device 24 provided in this embodiment includes a first mounting seat 241 and a notch punching mechanism 242 arranged on the left side of the first mounting seat 241. The notch punching mechanism 242 is arranged on the left side to punch out the notch 151 corresponding to the left folding edge part 132.

[0119] The roller forming device 25 provided in this embodiment includes a first roller pressing group 251 and a first roller transport group 252. The first roller pressing group 251 is arranged on the left side of the frame of the roller forming device 25, and the first roller transport group 252 is arranged on the right side of the frame. The roller pressing group is used for roller forming of the folding part on the left side of the front tongue plate 13.

[0120] The irregular reinforcing rib 131 has an inclined surface, and the rib depth changes gradually. The rib surface is inclined from high to low from the left side to the right side of the front tongue plate 13. Fig.19 .

[0121] The punching and convex rib device 22 provided in this embodiment is different from the punching and convex rib device 22 in the forming production line 2 of the middle rib plate in that the reinforcing rib of the middle rib plate 11 in the forming production line 2 of the middle rib plate is a rectangular rib structure, and the corresponding first die cavity 2223, second die cavity 2213 and die piece 2224 are all rectangular regular structures, while the reinforcing rib of the front tongue plate 13 in this embodiment is an irregular rib structure, and the corresponding first die cavity 2223, second die cavity 2213 and die piece 2224 are all irregular structures, as shown in the structure. Figure 21-22 .

[0122] The forming production line of the inclined rib plate 5, such as Figure 23-28 .

[0123] The structure of the oblique rib plate 14 is as follows Fig.23 , the forming of the diagonal rib plate 14 includes a third flange 141 part.

[0124] Fig.24 A forming production line 5 for an inclined rib plate is provided, which includes a feeding device, a feeding positioning device 51, a forming roller device 52, a straightening device 53, a discharging device and a central control system arranged in sequence along the transport route of the plate rib member 15, so as to realize a structure (such as a trapezoidal or triangular steel section with a groove cross section) that can be formed by pressing a trapezoidal plate 16 cut into a trapezoid through the inclined rib plate 14 forming machine. Fig.23 ).

[0125] The feeding device is composed of a material taking mechanical arm and a material storage platform. A stack of trapezoidal plates 16 cut into trapezoidal shapes is stacked on the material storage platform. The trapezoidal plates 16 are taken by the material taking mechanical arm and then transported to the feeding positioning device 51. The material taking mechanical arm can use a suction cup structure to suck and transport the trapezoidal plates 16. The material taking mechanical arm can use an existing mechanical arm to realize the function of feeding.

[0126] like Fig.25 The feeding positioning device 51 includes a support frame 511 and a feeding platform 512. Two second rails 513 are arranged in parallel on the left and right sides of the support frame 511. A movable seat 514 is arranged at the bottom of the feeding platform 512 corresponding to the second rails 513 on both sides. The movable seat 514 is slidably matched with the second rails 513. A driving cylinder 515 (such as Fig.25), the rear side of the support frame 511 is the feeding side, and the trapezoidal sheet 16 is pushed into the forming roller device 52 by the feeding side for the pressing process. The driving end of the driving cylinder 515 is connected to the feeding platform 512, and the driving cylinder 515 can perform forward and backward telescopic movement, thereby driving the feeding platform 512 to move forward and backward along the second track 513, so as to push the trapezoidal sheet 16 into the forming roller device 52.

[0127] Since the trapezoidal plate 16 is a trapezoidal structure, when the trapezoidal plate 16 is placed on the feeding table 512, the bevel of the trapezoidal plate 16 needs to be corrected. Therefore, a positioning assembly is provided on the feeding table 512. The positioning assembly includes a first positioning plate 516 and a second positioning plate 517 (such as Fig.26 ), the first positioning plate 516 is centrally arranged on the feeding table 512, and the first positioning plate 516 is arranged at a position close to the rear side of the feeding table 512, and the rear side is the side away from the forming roller device 52. The first positioning plate 516 is arranged horizontally, and is used for positioning one side straight edge of the trapezoidal plate 16, and the side straight edge is the side that is finally pushed into the forming roller device 52. The second positioning plate 517 is arranged on one side of the first positioning plate 516, and the second positioning plate 517 is provided with a rotating mechanism. The second positioning plate 517 can be rotated by the rotating mechanism, and the second positioning plate 517 swings along a circle in the plane of the feeding table 512. The second positioning plate 517 is used for positioning the trapezoidal hypotenuse of the trapezoidal plate 16. The hypotenuse of the trapezoidal plate 16 is pushed to be straightened by the rotation of the second positioning plate 517. The positions of the first positioning plate 516 and the second positioning plate 517 and the cooperation with the trapezoidal plate 16 are as shown in Fig.25 .

[0128] The rotation angle of the second positioning plate 517 can be set through the central control system. It is known that the angle between the straight edge on one side of the trapezoidal plate 16 and the trapezoidal hypotenuse is a°. The rotation matching angle between the extension line of the first positioning plate 516 and the second positioning plate 517 is set to be a°. The first positioning plate 516 is in a fixed position, and the second positioning plate 517 is rotatable. By setting the rotation angle of the worm gear, the second positioning plate 517 is driven to rotate and swing until it forms an angle of a° with the extension line of the first positioning plate 516. The rotation angle of the worm gear is set to A°. After the swing angle of the second positioning plate 517 is set to a fixed value each time, the trapezoidal plate 16 is loaded. The position of the trapezoidal plate 16 is corrected by rotating and swinging the second positioning plate 517 at a fixed angle in cooperation with the first positioning plate 516.

[0129] like Fig. 27The forming roller device 52 includes a second roller pressing group 521 and a second roller transporting group 522. The second roller pressing group 521 is used to plastically deform the trapezoidal plate 16, and the second roller transporting group 522 is used to transport the trapezoidal plate 16. The second roller pressing group 521 includes two groups of roller assemblies 523 arranged on the left and right sides, which are used to press the two oblique sides of the trapezoidal plate 16, so that the trapezoidal plate 16 is pressed to form a groove-shaped cross-section structure.

[0130] The second roller pressing group 521 and the second roller transport group 522 both include an upper pressing roller and a lower pressing roller, and the upper pressing rollers and the lower pressing rollers on both sides are symmetrically arranged. By setting the pressing rollers at different heights and setting different pressing surfaces at different angles, the rollers are configured to rotate continuously and press the oblique edges of the trapezoidal plate 16 at corresponding pressures and speeds, causing it to bend and deform, thereby forming the structure of the oblique rib plate 14.

[0131] The forming roller device 52 can adopt an existing roller forming machine that can press the trapezoidal plate 16 into a C-shaped steel shape through a series of rollers through continuous rolling action.

[0132] The straightening device 53 is arranged at the output end of the forming roller device 52, and is used to shape the waist height of the trapezoidal plate 16 after forming, so as to prevent the third folding edge 141 from having standing edge waves, waist reduction, and other phenomena. The straightening device 53 is provided with two straightening mechanisms (such as Fig.28 ), and the two straightening mechanisms are staggered front and back. The straightening mechanism includes a support seat 531 and a first vertical pressure roller 532 and a second vertical pressure roller 533 installed on the support seat 531, and the first vertical pressure roller 532 and the second vertical pressure roller 533 are both unpowered pressure rollers, and both roll with the transportation of the formed oblique rib plate 14. There is a gap between the first vertical pressure roller 532 and the second vertical pressure roller 533, and the gap allows the third folded edge 141 to pass through after bending. The third folded edge 141 after bending is pressed by the first vertical pressure roller 532 and the second vertical pressure roller 533 to form a right-angled structure (such as Fig.28 ).

[0133] The support seat 531 includes a mounting plate 534, a first vertical pressure roller 532 is fixed on the mounting plate 534, a second vertical pressure roller 533 is movably mounted on the mounting plate 534, a mounting block 535 is provided at the mounting end of the second vertical pressure roller 533, the mounting plate 534 is provided with a second mounting groove 536 corresponding to the mounting block 535, the mounting block 535 is provided with an adjustment rod 537 on a side away from the first vertical pressure roller 532, and the adjustment rod 537 passes through the second mounting groove 536 (such as Fig.28), the adjusting rod 537 can drive the mounting block 535 to move in the second mounting groove 536 in a direction close to or away from the first vertical pressure roller 532, thereby driving the second vertical pressure roller 533 to adjust the distance between it and the first vertical pressure roller 532, so as to adapt the thickness of the plate reinforcement member 15.

[0134] The processing flow of the inclined rib plate 14 forming machine is as follows: a trapezoidal plate 16 that has been cut into a trapezoid is transported from a loading device to a feeding positioning device 51; the trapezoidal plate 16 is placed on a feeding table 512, and a straight edge of one side of the trapezoidal plate 16 is against the side of a first positioning plate 516, and the second positioning plate 517 is rotated to align the trapezoidal bevel of the trapezoidal plate 16; after alignment, the driving cylinder 515 drives the feeding table 512 forward to push the trapezoidal plate 16 to the forming roller device 52; until all the trapezoidal plates 16 are transported to the forming roller device 52, the driving cylinder 515 drives the feeding table 512 to reset and wait for the next trapezoidal plate 16 to be loaded.

[0135] The trapezoidal plate 16 is pressed into a C-shaped structure by a series of rollers in the forming roller device 52 to form an inclined rib plate 14 through continuous rolling action, and is transported by the second roller transport group 522 and output from the forming roller device 52 to the straightening device 53; after rolling, the third folded edge 141 of the plate rib 15 enters the straightening mechanism, and the third folded edge 141 is pressed and shaped by the first vertical roller 532 and the second vertical roller 533; the finally formed inclined rib plate 14 is output by the straightening mechanism and enters the discharging device, which includes an output roller, and under the action of the output roller, the formed inclined rib plate 14 is transported to the discharging conveyor belt for the next process. The final formed inclined rib plate 14 is output by the discharging device.
