[0061] like Figure 1-19 The present embodiment provides a center rib plate forming machine, wherein a feed leveling device 1, a rib punching device 2, a die punching device 3, a notch punching device 4, a roller forming device 5, a shearing device 6 and a front and rear folding device 7 are sequentially arranged along the conveying direction of the plate rib member 9, and each device is automatically driven by a computer control cabinet and a hydraulic control center to realize the side rib plate pressing and forming.

[0062] The feed leveling device 1 is provided with a series of rollers for guiding the plate rib member 9 for processing and conveying; the rib punching device 2 is used for punching the reinforcing ribs 91 on the plate rib member 9; the die punching device 3 is used for punching the trademark and digital logo on the plate rib member 9; the notch punching device 4 is used for punching the notches 92 of the folded edge parts 93 on the left and right sides of the plate rib member 9 to reduce the stress of the plate rib member 9 when bending; the roller forming device 5 is used for bending and roller pressing the folded edge parts 93 on the left and right sides of the plate rib member 9; the shearing device 6 is used for shearing the plate rib member 9, and cutting according to the required length of the middle rib plate 96 to form pieces of middle rib plates 96; the front and rear folding devices 7 are used for bending the flange parts 94 on the front and rear sides of the middle rib plate 96.

[0063] The feed leveling device 1 provided in this embodiment includes an upper roller pressing group 11 and a lower roller pressing group 12 (such as Fig.19 ), the plate rib part 9 passes between the upper roller pressing group 11 and the lower roller pressing group 12. The upper roller pressing group 11 and the lower roller pressing group 12 are cooperated with each other by using four upper rollers and three lower rollers to flatten the plane of the plate rib part 9, thereby ensuring the flatness of the plate surface of the plate rib part 9 and facilitating the subsequent die pressing process of the rib punching device 2.

[0064] like Fig.19 The feeding and leveling device 1 also includes a counting wheel 13 and an introduction device. The counting wheel 13 is used to record the length of the plate rib 9. The introduction device is used to introduce the plate rib 9 into the punching and convex rib device. The introduction device includes an introduction plate 14 and introduction blocks 15 arranged on both sides of the introduction plate 14. The side of the introduction block 15 away from the punching and convex rib device 2 is provided with a second guide slope 16. The second guide slope 16 facilitates the introduction of the plate rib 9 between the upper roller pressing group 11 and the lower roller pressing group 12, and cooperates with the introduction block 15 to continue to introduce the punching and convex rib device 2. The introduction blocks 15 on both sides are slidably installed on the introduction plate 14. The introduction blocks 15 on both sides can move closer to or away from each other, which is used to adjust the distance between the introduction blocks 15 on both sides, and is suitable for feeding and leveling of plate ribs 9 of different widths. The introduction plate 14 is provided with a second sliding groove 17. The introduction block 15 is installed in the second sliding groove 17 by a second bolt 18. By adjusting the tightness of the second bolt 18, the distance between the introduction blocks 15 on both sides can be adjusted.

[0065] The rib punching device 2 provided in this embodiment includes an upper die 21 and a lower die 22 (such as Figure 2 ), the plate rib part 9 is transported to the die surface of the lower die 22, and the upper die 21 moves downward relative to the lower die 22 to cooperate with the lower die 22 to manufacture the reinforcing ribs 91 of the plate rib part 9.

[0066] Specifically, the upper die 21 includes an upper die base 211 and a die assembly 212. The die assembly 212 is a driving member (such as Figure 7 ), used to drive the upper die base 211 to move up and down, the lower die 22 includes a lower die base 221, and the lower die base 221 includes a guide column 222 (such as Figure 5 ), the guide pillars 222 are arranged on the four sides of the lower die seat 221, and the upper die seat 211 is provided with guide holes 213 corresponding to the guide pillars 222. The upper die seat 211 is driven by the die assembly 212, and the guide holes 213 move vertically up and down along the guide pillars 222. The guide holes 213 cooperate with the guide pillars 222 to play a guiding role (such as Figure 4 In the initial state, the upper die seat 211 is driven by the die assembly 212 to rise, leaving a gap 23 between the upper die seat 211 and the lower die seat 221 (such as Figure 3 ), the gap 23 is used for the plate reinforcement member 9 to be transported through.

[0067] The lower die base 221 includes a first die cavity 223 and a die member 224 (such as a Figure 5 ), the die 224 can move up and down vertically, the upper die base 211 includes a second die cavity 214 and a rib pressing module 215 (such as Figure 7 ), the rib pressing module 215 can move up and down in the vertical direction, and the first die cavity 223 and the second die cavity 214 are correspondingly arranged. When the reinforcing rib 91 of the plate rib part 9 is pressed, the die 224 moves upward and extends out of the first die cavity 223, and continues to press the plate rib part 9 upward. The rib part of the plate rib part 9 is raised under the pressing of the die 224. The die 224 presses the plate rib part 9 to protrude into the second die cavity 214. The second die cavity 214 provides space for the rib part to bulge and deform. Under the upward pressing of the die 224, the rib pressing module 215 shrinks inward along the second die cavity 214 to make way for the protrusion of the rib part. The structure of the reinforcing rib 91 of the plate rib part 9 after rib pressing is as shown in FIG. Fig.18 .

[0068] The lower die 22 includes a die drive assembly 225, which is connected to the die piece 224 via a first reversing member 226. The die drive assembly 225 moves horizontally and drives the die piece 224 to move vertically via the first reversing member 226, so as to press the reinforcing rib 91. The die drive assembly 225 includes a telescopic gas rod 2251 and a moving block 2252 connected to the telescopic gas rod 2251. The first reversing member 226 includes a first inclined surface 2261 disposed on the die piece 224 and a second inclined surface 2262 disposed on the moving block 2252 (such as Figure 4 ), the first inclined surface 2261 and the second inclined surface 2262 are arranged to be inclined in opposite directions, and the first inclined surface 2261 and the second inclined surface 2262 are movably matched, and the reversing drive is realized by the inclined match of the two inclined surfaces. In the initial state, the die 224 is placed in the first die cavity 223. When the reinforcing rib 91 is pressed, the die 224 is driven by the die driving assembly 225 to protrude upward from the first die cavity 223, and the protruding height is the depth of the reinforcing rib 91.

[0069] The upper mold 21 includes a demolding mechanism, which is used to demold the reinforcing ribs 91 protruding into the second cavity. The demolding mechanism includes a die plate 216 and a demolding assembly 217. The die plate 216 is connected to the die assembly 212. The die assembly 212 drives the die plate 216 to move up and down. The die plate 216 is connected to the upper mold base 211. The movement of the die plate 216 causes the upper mold base 211 to move vertically up and down to achieve molding and demolding. The demolding assembly 217 is arranged between the second die cavity 214 and the rib pressing module 215 (such as Figure 7), during pressing, the rib pressing module 215 squeezes the demolding assembly 217 under the top action of the die 224 and retracts toward the second die cavity 214. Under the action of the demolding assembly 217, the rib pressing module 215 is initially flush with the die surface of the upper die seat 211 (such as Fig. 9 ), when the rib pressing module 215 retracts, the demolding component 217 can be squeezed to accumulate force, and the demolding component 217 provides the rib pressing module 215 with an outward thrust toward the die cavity for demolding.

[0070] like Figure 8 A second reversing member 218 is provided between the die assembly 212 and the die plate 216. The die assembly 212 moves laterally, and the die plate 216 moves vertically through the second reversing member 218. The die assembly 212 includes a driving cylinder 2121 and a pressing plate 2122. The pressing plate 2122 can move laterally under the drive of the driving cylinder 2121. The second reversing member 218 includes an inclined surface 2181 provided on the pressing plate 2122 and two inclined surfaces 2182 provided on the die plate 216. The inclined surface 2181 and the two inclined surfaces 2182 are arranged to be tilted in opposite directions, and the inclined surface 2181 and the two inclined surfaces 2182 are movably matched, and the reversing drive is realized through the tilting match of the two inclined surfaces.

[0071] When the driving cylinder 2121 drives the pressing plate 2122 to move horizontally, the first inclined surface 2181 and the second inclined surface 2182 are pressed against each other, and the first inclined surface 2181 moves horizontally to press the second inclined surface 2182. Under the action of the inclined surfaces, the pressing plate 216 moves vertically under the action of the two inclined surfaces 2182, thereby causing the upper die holder 211 to move downward. In this embodiment, two sets of pressing die assemblies 212 are selected to be arranged on both sides of the pressing plate 216, and the two pressing plates 2122 are arranged at an interval, and the interval is provided for the two pressing plates 2122 to move relative to each other horizontally (such as Figure 8 ).

[0072] like Figure 8 The demolding assembly 217 includes an elastic member 2171, which may be a spring. The elastic member 2171 is disposed between the rib pressing module 215 and the die cavity. The rib pressing module 215 squeezes the elastic member 2171 and moves inward toward the die cavity. Fig. 9 The upper die base 211 includes an upper die plate 2111 and a lower die plate 2112. The upper die plate 2111 is fixed to the lower die plate 2112 and the pressing die plate 216 respectively. The lower die plate 2112 is provided with a through slot 2113. The through slot 2113 and the rib pressing module 215 are adapted to the size of the reinforcing rib 91 to be pressed. The through slot 2113 cooperates with the end surface of the upper die plate 2111 to form a second pressing die chamber 214. The rib pressing module 215 is placed in the through slot 2113. The two ends of the elastic member 2171 are fixed to the end surface of the upper die plate 2111 and the rib pressing module 215 respectively.

[0073] like Fig. 9A first guide groove 2114 is provided on the upper mold plate 2111, and the elastic member 2171 is placed in the first guide groove 2114, and one end is fixed to the bottom of the first guide groove 2114. When the rib pressing module 215 is pressed and retracted, the elastic member 2171 is squeezed into the first guide groove 2114, and the first guide groove 2114 provides a guiding force for the elastic member 2171 to retract, and at the same time provides stability for the elastic deformation of the elastic member 2171. When the pressing force disappears, the rib pressing module 215 begins to move outward along the second die cavity 214 under the elastic force of the elastic member 2171, and the elastic force of the elastic member 2171 acts on the rib pressing module 215 to pop out instantly, so that the reinforcing rib 91 is pushed out instantly, achieving precise demolding and improving demolding efficiency.

[0074] When the rib pressing and convex rib device 2 is used, the plate rib member 9 to be pressed is transported to the gap 23 between the upper die seat 211 and the lower die seat 221, and the plate rib member 9 to be pressed is placed on the die surface of the lower die seat 221. The upper die seat 211 is driven downward by the die assembly 212 and pressed on the plate rib member 9, so that the plate rib member 9 is attached between the die surfaces of the upper die seat 211 and the lower die seat 221. In the rib pressing process, the die driving assembly 225 drives the die member 224 to convex upward along the first die cavity 223, and the die member 224 acts on the corresponding part of the plate rib member 9.
