[0050] refer to Figures 1-13 This embodiment provides a front tongue plate 7 forming machine. Along the conveying direction of the plate rib 74, a feeding leveling device 1, a pressing and punching rib device 2, a punching notch device 3, a roll forming device 4, a shearing device 5, and a front and rear folding head device 6 are arranged in sequence. 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.

[0051] The pressing process of the front tongue plate 7 includes pressing the irregular reinforcing rib 71, pressing the folded edge portion 72 on one side of the left and right sides, and pressing the flanged edge portion 73 on the front and rear sides. The irregular reinforcing rib 71 has a sloping surface and a gradient change in rib depth. The rib surface slopes from high to low from the left side to the right side of the front tongue plate 7, and the folded edge portion 72 is provided on its left side.

[0052] like Figure 1 The feeding and leveling device 1 is equipped with a series of rollers for guiding the reinforcing rib 74 into the processing and conveying process; the pressing and punching rib device 2 is used for pressing the reinforcing rib 71 on the reinforcing rib 74; the punching notch device 3 is used for punching the notch 75 of the folded edge portion 72 of the reinforcing rib 74 to reduce the stress when the reinforcing rib 74 is bent; the roll forming device 4 is used for bending and rolling the folded edge portion 72 of the reinforcing rib 74; the shearing device 5 is used for shearing the reinforcing rib 74, cutting it according to the required length of the front tongue plate 7 to form pieces of the front tongue plate 7; the front and rear folding head device 6 is used for bending the folded edge portion 73 on the front and rear sides of the front tongue plate 7.

[0053] The feeding leveling device 1 provided in this embodiment includes an upper roller pressing group 11 and a lower roller pressing group 12 (e.g., ...). Figure 13The rib 74 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 equipped with four upper rollers and three lower rollers to flatten the plane of the rib 74, ensuring the flatness of the rib 74 and facilitating the subsequent pressing process of the stamping rib device 2.

[0054] The feeding and leveling device 1 also includes a counting wheel 13 and an infeed device. The counting wheel 13 is used to record the length of the rib piece 74 as it travels, and the infeed device is used to guide the rib piece 74 into the stamping and rib-forming device. The infeed device includes an infeed plate 14 and infeed blocks 15 disposed on both sides of the infeed plate 14. A second guide slope 16 is provided on the side of the infeed block 15 facing away from the stamping and rib-forming device 2. The second guide slope 16 facilitates the infeeding of the rib piece 74 between the upper roller pressing group 11 and the lower roller pressing group 12, and continues to guide it into the stamping and rib-forming device 2 in conjunction with the infeed block 15. The infeed blocks 15 on both sides are slidably mounted on the infeed plate 14. The infeed blocks 15 on both sides can move closer to or further away from each other to adjust the distance between the two infeed blocks 15, which is suitable for feeding and leveling rib pieces 74 of different widths. A second sliding groove 17 is provided on the infeed plate 14. The infeed blocks 15 are installed in the second sliding groove 17 by a second bolt 18. The distance between the two infeed blocks 15 can be adjusted by adjusting the tightness of the second bolt 18.

[0055] The stamping rib device 2 provided in this embodiment includes a first stamping die 21 and a second stamping die 22 arranged vertically. The first stamping die 21 is located above, and the second stamping die 22 is located below. A stamping die driving member 211 is connected to the first stamping die 21. Under the drive of the stamping die driving member 211, the first stamping die 21 moves closer to or away from the second stamping die 22. Figure 2 .

[0056] In the initial state, the first pressing mold 21 moves upward under the drive of the pressing mold drive 211, and there is a clearance between it and the second pressing mold 22. This clearance is used for the input of the rib 74. After the rib 74 is input, it is placed on the pressing surface 23 of the second pressing mold 22. During pressing, the first pressing mold 21 moves downward under the drive of the pressing mold drive 211 and presses the rib 74 to form a pressing mold fixation between the first pressing mold 21 and the second pressing mold 22.

[0057] The first molding component 21 includes a first mold base 212 and a first pressing cavity 213 disposed on the first mold base 212. The first pressing cavity 213 is disposed on the molding surface 23 of the first molding component 21, and the first pressing cavity 213 is formed by the concavity of the molding surface 23 to create a cavity with a gradient in depth. The pressing inlet of the first pressing cavity 213 is set as a teardrop-shaped pressing inlet, such as... Figure 3 .

[0058] The second molding component 22 includes a second mold base 221 and a second pressing cavity 222 disposed on the second mold base 221. The second pressing cavity 222 is disposed on the pressing surface 23 of the second molding component 22, and a pressing element 223 is disposed within the second pressing cavity 222. The second pressing cavity 222 includes a chamber for the pressing element 223 to move. The pressing element 223 is configured as a molding block 636 with a height gradient, and the pressing surface of the pressing element 223 is a teardrop-shaped pressing surface, such as... Figure 3 .

[0059] The first pressing chamber 213 and the second pressing chamber 222 are arranged opposite to each other and can communicate with each other. A pressing drive 224 is provided on the second mold base 221. The pressing member 223 moves from the second pressing chamber 222 to the first pressing chamber 213 under the drive of the pressing drive 224. When the rib member 74 is pressed between the first pressing mold member 21 and the second pressing mold member 22, the pressing member 223, driven by the pressing drive 224, lifts the pressed part of the reinforcing rib 71 of the rib member 74 and performs convex pressing deformation towards the first pressing chamber 213. The pressing member 223 cooperates with the first chamber to complete the pressing of the reinforcing rib 71. After pressing, a reinforcing rib 71 with a gradient depth and a sloping surface is formed. The cross-section of the reinforcing rib 71 is teardrop-shaped. The shape of the reinforcing rib 71 is as follows. Figure 5 .

[0060] The die-cutting drive component 211 includes a die-cutting cylinder and a first reversing assembly, and the die-cutting drive component 224 includes a die-cutting cylinder and a second reversing assembly. The function of the first and second reversing assemblies is to reverse the lateral extension and retraction drive of the die-cutting cylinder and the die-cutting cylinder into vertical up-and-down movement, thereby realizing the vertical up-and-down movement of the first die-cutting component 21 and the die-cutting component 223 to perform the die-cutting process. The first and second reversing assemblies can be implemented by using two inclined surfaces with opposite orientations, or other components capable of reversing in the prior art. These will not be described in detail here.

[0061] In this embodiment, considering that the reinforcing rib 71 of the front tongue plate 7 is an irregular rib structure with a sloping surface and a gradient in rib depth, an irregularly structured pressure block 636 is used in conjunction with an irregularly structured first pressure cavity 213 for pressing, and the processing can be completed in one molding process. By continuously rising the pressure piece 223, pressure is applied to the plate rib 74 at different height stages to form the required shape and depth, simplifying the rib pressing process. Furthermore, due to the irregular structure of the first pressure cavity 213, the first molding piece 21 is easier to demold when driven upward by the molding drive piece 211.

[0062] The punching notch device 3 provided in this embodiment includes a first mounting base 31 and a punching notch mechanism 32 disposed on the left side of the first mounting base 31. The punching notch mechanism 32 is used for punching the notch 75 of the folded portion 72 (e.g., Figure 5The punching mechanism 32 includes a hydraulic cylinder 33 and a punch 34 (e.g., Figure 6 The hydraulic cylinder 33 drives the punch 34 downward to punch the notch 75 in the folded edge portion 72 of the rib member 74, forming the notch 75. This notching mechanism 32 can use an existing notching machine, which will not be described in detail here.

[0063] The roll forming apparatus 4 provided in this embodiment includes a roll pressing group 41 and a roll transport group 42, such as Figure 7 A roller pressing group 41 is set on the left side of the frame of the roller forming device 4, and a roller transport group 42 is set on the right side of the frame. The roller pressing group 41 is used for the roller forming of the folded edge portion 72 on the left side of the front tongue plate 7.

[0064] The roller pressing group 41, through the different height settings of the pressure rollers and the different angles of the different pressing surfaces, presses the folded edge portion 72 under corresponding pressure and speed during the continuous rotation of the rollers, causing it to bend and deform. The roller transport group 42 is used for transporting the rib member 74. This roll forming device 4 can be an existing roll forming machine that can press the rib member 74 into a folded edge through a series of rollers using continuous rolling action, which will not be described in detail here.

[0065] The shearing device 5 provided in this embodiment is a follow-through shear. The shearing device 5 includes a cutter assembly 52 and a second mounting base 51. The cutter assembly 52 is slidably engaged with the second mounting base 51, and the cutter assembly 52 slides back and forth relative to the second mounting base 51 via a cutting drive mechanism. The cutter assembly 52 includes a cutting table 53 and a cutter assembly 54. A slide 55 is provided at the bottom of the cutting table 53, and a track 56 is provided on the second mounting base 51. The slide 55 is slidably mounted on the track 56 and slides along the length of the track 56. Figure 8 .

[0066] The cutting table 53 includes a cutting window, and the cutting assembly 54 includes a cutting blade 541 and a cutting drive air rod 542. The cutting blade 541 is placed inside the cutting window and is driven vertically downward by the cutting drive air rod 542 to cut the rib member 74. The following shearing process is as follows: when the rib member 74 is transported to the shearing device 5, the position to be cut of the rib member 74 is placed in the cutting window. The cutting table 53 slides under the drive of the cutting drive mechanism. The sliding direction is consistent with the transport direction of the rib member 74, and the sliding speed is consistent with the transport speed of the rib member 74. The rib member 74 does not stop transporting, and the rib member 74 is cut by the following shearing blade 541 during the transport process. After the following shearing completes the cut, the cutting table 53 is driven and reset by the cutting drive mechanism to perform the next following shearing. In order to facilitate the subsequent bending of the front and rear folding device 6, the flanged part 73 does not interfere with the folded part 72. The cutting position of the cutting blade 541 is located in the notch 75 of the first folded part 72.

[0067] The front and rear folding device 6 provided in this embodiment includes a support frame 61 and a folding machine 62 disposed in the support frame 61. The folding machine 62 includes folding parts 63 disposed on the front and rear sides. The rib 74 is transported to the folding machine 62 by a conveying device, and the folding parts 63 perform the bending operation of the folded edge portion 73 of the rib 74.

[0068] like Figure 9 The bending machine 62 includes a machine base 621, with third mounting seats 622 on the left and right sides of the machine base 621. A worktable 623 is provided in the middle of the machine base 621, which is used to place the rib member 74 to be bent. The bending member 63 is vertically provided with a first pressure plate 631 and a second pressure plate 632. The first pressure plate 631 is used to bend the flanged portion 73 of the rib member 74, and the second pressure plate 632 is used to connect the piston rod 64 of the hydraulic cylinder. The first pressure plate 631 and the second pressure plate 632 are connected. Rotating shafts 633 are provided on both sides of the first pressure plate 631, and are rotatably mounted on the third mounting seats 622 on both sides through the rotating shafts 633. The inner side of the first pressure plate 631 abuts against the side of the worktable 623.

[0069] like Figure 10 Two sets of folding parts 63 are set on the front and rear sides of the workbench 623. The hydraulic cylinder piston rod 64 is installed at the bottom of the support frame 61, and the extension end of the hydraulic cylinder piston rod 64 is connected to the second pressure plate 632. The hydraulic cylinder piston rod 64 is set at an angle to the ground and is inclined. When the extension end of the hydraulic cylinder piston rod 64 extends or retracts, the second pressure plate 632 rotates around the rotating shaft 633, thereby realizing the bending operation of the first pressure plate 631 on the plate rib 74.

[0070] In the initial state, the telescopic end of the hydraulic cylinder piston rod 64 is retracted, the second pressure plate 632 is placed vertically, and the first pressure plate 631 is placed horizontally. The pressing surface of the first pressure plate 631 is used to place the flanged portion 73 of the rib member 74. During the bending operation, the telescopic end of the hydraulic cylinder piston rod 64 extends, and the first pressure plate 631 is flipped along the rotation axis 633 under the drive of the telescopic end. The second pressure plate 632 is placed horizontally, and the first pressure plate 631 is flipped upwards to be placed vertically. The flanged portion 73 bends as the first pressure plate 631 flips upwards.

[0071] like Figure 11The outer side of the first pressure plate 631 is provided with a first guide slope 634 for guiding or guiding the rib member 74. An installation groove 635 is provided on the inner side of the first pressure plate 631, within which several pressure blocks 636 can be detachably installed. These pressure blocks 636 are arranged and assembled within the installation groove 635, and the number of pressure blocks 636 within the installation groove 635 is adjustable. The outermost pressure block 636 within the installation groove 635 corresponds to the end position of the flanged portion 73. The number of pressure blocks 636 is determined according to the length of the flanged portion 73, leaving space on the side of the installation groove 635. When the first pressure plate 631 is pressed upwards, the reserved space 65 on the side of the installation groove 635 allows for the left-side fold of the rib member 74, preventing interference with the first pressure plate 631.

[0072] like Figure 11 A mounting rib 637 is provided at the bottom of the mounting groove 635, and a positioning groove 638 is provided at the bottom of the pressure block 636. The positioning groove 638 and the mounting rib 637 are positioned and installed. Screw holes 639 are provided on both sides of the mounting rib 637 in the mounting groove 635. The pressure block 636 is secured by screws, and the pressure block 636 can be removed by removing the screws. In this embodiment, two sets of mounting grooves 635 and pressure blocks 636 are arranged at intervals along the inner length of the first pressure plate 631, which simplifies the structure, saves the number of pressure blocks 636, and reduces costs.

[0073] Limiting blocks 624 are provided on the worktable surface 623, and two sets of limiting blocks 624 are provided on the left and right sides of the worktable surface 623.
