DETAILED DESCRIPTION
[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0026] like Figure 1 As shown, an automatic forming production line for air valve blades comprises an unwinding frame 2, a leveling frame and a conveying roller frame 7 which are arranged in sequence, and a forming machine 9 is arranged on one side of the conveying roller frame 7; a material guiding mechanism 3, a leveling mechanism 4, a punching mechanism 5 and a cutting mechanism 6 are arranged in sequence on the leveling frame, and a plurality of leveling rollers 41 and a first servo motor for driving each leveling roller 41 to rotate are arranged on the leveling mechanism 4; a plurality of parallelly arranged conveying rollers 71 are arranged on the top of the conveying roller frame 7, and a second servo motor 72 which can drive each conveying roller 71 to rotate synchronously is also fixed on the conveying roller frame 7; the production line also comprises two feeding mechanisms, one of which is located in the conveying roller frame 7, and the other is located in the forming machine 9, and the cooperation of the two feeding mechanisms can realize the clamping of the galvanized sheet a and the translation along the axial direction of the conveying roller 71; a pair of forming dies 91 are arranged on the forming machine 9, and the pair of forming dies 91 can process a groove 11 on the galvanized sheet a by one mold closing.
[0027] Working principle: The galvanized sheet a coil is installed on the unwinding rack 2, and its outer end is pulled onto the leveling rack, and passes through the material guide mechanism 3, the leveling mechanism 4, the punching mechanism 5 and the cutting mechanism 6 in sequence. The leveling mechanism 4 is driven by the first servo motor, and the galvanized sheet a will be leveled under the action of each leveling roller 41, and pulled and transported to the downstream processing mechanism; the punching mechanism 5 can process the installation hole 12 on it, and the cutting mechanism 6 can cut it according to the size of the blade to be produced; the cut galvanized sheet a falls on the conveying roller rack 7, and is conveyed to the predetermined position by each conveying roller 71; then the two feeding mechanisms are started, and the galvanized sheet a is transported to the forming mold 91 of the forming machine 9 for stamping and forming processing, and multiple grooves 11 are formed on the galvanized sheet a one by one, completing the stamping and forming operation of the air valve blade. This automatic forming production line can burn the program on the encoder, and each mechanism is also equipped with a sensor for positioning, so that each action is automatically and orderly completed under the control of the controller, which can be completely unmanned. And it is not necessary to customize molds of various specifications according to the size of the air valve blade, so that it has better versatility. Its processing method of punching the grooves 11 one by one can also improve the distortion of the galvanized sheet a caused by punching, making the blade flatter.
[0028] like Figure 1 and Figure 2 As shown, each feeding mechanism includes a third servo motor 73 and a first slide rail 74, each first slide rail 74 is slidably connected to a first slide 75, a crossbeam 76 is provided above each first slide 75, and a plurality of vertically mounted first cylinders 77 are provided between each crossbeam 76 and the corresponding first slide 75 to connect them; a plurality of clamps 78 are arranged at intervals on each crossbeam 76, and the clamps 78 on the two feeding mechanisms are symmetrically arranged; each clamp 78 on the first feeding mechanism is located between two adjacent conveying rollers 71; each third servo motor 73 is transmission-connected to the output shaft with a first screw rod 79, and each first screw rod 79 can drive the first slide 75 to slide on the first slide rail 74.
[0029] After the galvanized sheet a enters the predetermined position on the top of the conveying roller frame 7, the third servo motors 73 on the two feeding mechanisms are started synchronously, and the two first slides 75 are driven by the screw rod to move toward each other until the clamps 78 on the two feeding mechanisms are clamped on both sides of the galvanized sheet a together; then, each first cylinder 77 is started to lift the galvanized sheet a together to make it leave the conveying rollers 71; finally, the two third servo motors 73 drive the two slides to move synchronously in the same direction, so that the clamped galvanized sheet a is translated and conveyed to the forming machine 9, and the groove stamping and forming operation is performed one by one.
[0030] like Figure 1 and Figure 3As shown, a turning mechanism 8 is also provided between the forming machine 9 and the conveying roller frame 7, and the turning mechanism 8 includes a door-type frame 81; a pair of second slide rails 82 are provided on the top of the door-type frame 81, and second slides 83 are slidably connected to the two second slide rails 82; two second cylinders 84 are also fixed on the top of the door-type frame 81, and the two second cylinders 84 can respectively drive the two second slides 83 to slide on the second slide rails 82; a mounting plate 85 is suspended and fixed at the bottom of each second slide 83, and a third slide rail 86 is vertically fixed on each mounting plate 85, and a third slide 87 is slidably connected to each third slide rail 86, and a third cylinder 88 that can drive the third slide 87 to slide on the third slide rail 86 is also fixed on each mounting plate 85; a rotating cylinder 89 is fixed on an opposite surface of the two third slides 87, and a clamping block 891 is fixed on the output shaft of each rotating cylinder 89.
[0031] Since the grooves on some damper blades have different bending directions, the galvanized sheet a needs to be turned over during stamping to punch out grooves in the opposite direction to the previous direction, and the turning mechanism 8 can achieve this. When the galvanized sheet a is flipped, the two second cylinders 84 are first actuated to drive the two second slides 83 to slide toward each other, thereby driving the mounting plate 85 and the two clamping blocks 891 to move toward each other, until the two clamping blocks 891 are respectively clamped on both sides of the galvanized sheet a; then, the feeding mechanism releases the galvanized sheet a, and the two third cylinders 88 on the flipping mechanism 8 are synchronously actuated to drive the two third slides 87 to lift, thereby lifting the galvanized sheet a away from the feeding mechanism; then, the rotating cylinder 89 is actuated to rotate the galvanized sheet a clamped between the two clamping blocks 891 by 180°; finally, the third slide 87 and the second slide 83 return to their positions in sequence, and the galvanized sheet a is placed back on the feeding mechanism, which is clamped by the feeding mechanism to complete the stamping and forming work, thereby realizing the flipping of the galvanized sheet a.
[0032] like Figure 4 and Figure 5As shown, the punching mechanism 5 and the cutting mechanism 6 both include a bottom plate 51, and a top plate 53 is fixed on the top of each bottom plate 51 through a plurality of support rods 52, and a fourth cylinder 54 is vertically fixed on the top of each top plate 53; a punching die and a cutting die are respectively provided in the punching mechanism 5 and the cutting mechanism 6, and the punching die and the cutting die both include an upper die 55 and a lower die 56, and each lower die 56 is fixed on the corresponding bottom plate 51, and a plurality of first sliding rods 57 are fixed on the upper surface of the lower die 56, and each upper die 55 is slidably connected to the corresponding first sliding rods 57. a slide rod 57; a pressing plate 58 is provided between each upper mold 55 and the lower mold 56, and a second slide rod 59 is fixed on each pressing plate 58, and each second slide rod 59 is slidably connected to the corresponding upper mold 55; a plurality of springs 61 are provided between each upper mold 55 and the corresponding pressing plate 58 to connect them; a punching needle 62 and a cutting knife 63 are respectively fixed at the bottom of the upper mold 55 of the punching mold and the cutting mold, and avoidance holes for the punching needle 62 and the cutting knife 63 to pass through are respectively provided on the pressing plates 58 of the punching mold and the cutting mold.
[0033] When punching and cutting the galvanized sheet a, the galvanized sheet a passes through between the pressing plate 58 and the lower die 56, and the fourth cylinder 54 is actuated to drive the upper dies 55 downward, thereby driving the pressing plate 58 to move downward synchronously, so that the pressing plate 58 is pressed on the upper surface of the galvanized sheet a, and the fourth cylinder 54 continues to act, so that the punching needle 62 or the cutting knife 63 under the pressing plate 58 is continuously pressed downward to complete the punching or cutting operation of the galvanized sheet a. During this process, the pressing plate 58 is blocked by the galvanized sheet a, so the spring 61 is compressed, so that the pressing plate 58 is always pressed on the galvanized sheet a, and then during the punching and cutting operations, the galvanized sheet a is clamped and fixed, so that the cutting and punching positions are more accurate, the size error of the output damper blade is smaller, and the consistency is better.
[0034] like Figure 4 and Figure 5 As shown, the punching mechanism 5 also includes a fourth slide rail 64 and a fourth servo motor. The axis of the fourth slide rail 64 is perpendicular to the travel direction of the galvanized sheet a. The bottom plate 51 of the punching mechanism 5 is slidably connected to the fourth slide rail 64. The output shaft of the fourth servo motor is connected to the second screw rod 65, and the second screw rod 65 can drive the bottom plate 51 of the punching mechanism 5 to slide on the fourth slide rail 64. Since there are multiple mounting holes on the air valve blade, it is necessary to adjust the punching position to complete multiple punching operations. The mounting holes arranged along the travel direction of the galvanized sheet a can be adjusted by controlling the movement of the galvanized sheet a, while the mounting holes arranged in other directions require the lateral adjustment of the punching position, and the fourth slide rail 64, the fourth servo motor and the second screw rod 65 can just make the position of the punching mechanism 5 move lateral.
[0035] like Figure 6As shown, the material guide mechanism 3 includes a lower curved portion 31 and a horizontal portion 32. A plurality of guide rollers 33 are horizontally distributed in the lower curved portion 31. A fifth slide rail 34 is fixed in the horizontal portion 32. A pair of limit blocks 35 are slidably connected to the fifth slide rail 34. A plurality of limit rods 36 are arranged between the two limit blocks 35. A fifth servo motor is also arranged in the horizontal portion 32. A double-headed screw 37 is transmission-connected to the output shaft of the fifth servo motor. The double-headed screw 37 can drive the two limit blocks 35 to slide toward or in opposite directions on the fifth slide rail 34. The lower curved portion 31 and the guide rollers 33 in the material guide mechanism 3 can support and guide the galvanized sheet a to enter the leveling frame, while the two limit blocks 35 and the plurality of limit rods 36 can limit the travel route of the galvanized sheet a to prevent it from running off, so that the subsequent processing is more accurate. And we can adjust the distance between the two limit blocks 35 through the fifth servo motor and the double-headed screw 37, so that it can be suitable for the limited feeding of galvanized sheets a of various specifications.
[0036] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
