Description

Technical Field

[0001] The invention relates to the technical field of automobile stamping equipment, in particular to an automatic stamping and forming device for a vehicle door. Background Art

[0002] As one of the important parts of a car, the quality of the car door is directly related to the safety and ride comfort of the car. The automatic door stamping and forming device is a special equipment for automated stamping and forming of car door workpieces. It can ensure the accuracy and consistency of door forming, avoid the errors that may be caused by human operation, and thus improve the overall quality of the product.

[0003] For example, the invention patent disclosed in announcement number CN117282839B is a stamping equipment and stamping method for automobile parts stamping parts, which is applied in the field of stamping technology. It includes a frame on which a hydraulic cylinder, an upper die, a lower die, a blower, a heat dissipation unit, an oil tank, an oil outlet pipe, two oiling rollers and two conveying rollers are installed. The upper die is driven to slide by the hydraulic cylinder. The oil tank is connected to the oil outlet pipe through a connecting pipe. A piston is slidably installed in the oil outlet pipe. The two oiling rollers and the two conveying rollers rotate synchronously in opposite directions under the drive.

[0004] Although the above-mentioned equipment can perform stamping operations on automobile workpieces, it is not convenient for the above-mentioned equipment to simultaneously perform multi-level positioning and synchronous blanking operations on the workpiece during stamping.

[0005] For example, the invention patent disclosed in publication number CN115555453A discloses a stamping device for producing automobile stamping parts, comprising a scrubbing device, a stamping device being mounted on the right side of the scrubbing device, a scrubbing mechanism being mounted inside the scrubbing device, and an upper punch and a lower punch being mounted inside the stamping device;

[0006] Although the above equipment can perform stamping operations on automobile stamping parts, the above equipment has insufficient accuracy when loading and positioning the workpiece, and the efficiency of stamping and unloading the workpiece is also insufficient.

[0007] For example, the invention patent disclosed in publication number CN115555453A is a stamping device for stamping automobile sheet metal parts, which relates to the technical field of stamping equipment. The stamping device includes a frame, which is provided with: a support plate for supporting sheet metal, the support plate is provided with a driving member for driving the sheet metal material to move along the support plate; a stamping plate, the frame is provided with a rotating motor for driving the stamping rotation, the stamping plate is provided with a blanking hole and a plurality of punching holes, the diameters of all the punching holes are larger than the blanking holes, the blanking holes and all the punching holes are evenly arranged along the circumference of the stamping plate, and the diameters of all the punching holes are different;

[0008] Although the above-mentioned equipment can perform stamping operations on automotive workpieces of different diameters, the accuracy of its positioning of the workpiece during stamping is insufficient. At the same time, the coordination efficiency of the various modules of the above-mentioned equipment during stamping is insufficient, thereby reducing the overall stamping efficiency of the equipment on the workpiece.

[0009] In summary, although the above-mentioned equipment can perform stamping operations on automobile workpieces, there is still a large hysteresis between the various groups of processing equipment during the process of cyclic loading and stamping of automobile workpieces by the above-mentioned equipment, which reduces the speed at which the stamping equipment processes the workpieces. At the same time, the positioning accuracy of the above-mentioned equipment is also insufficient when stamping automobile workpieces, which reduces the accuracy of stamping automobile workpieces.

At the same time, the sliding limit of the fixed shaft sleeve 624, the circulating slide shaft 623, the circulating slide groove 68 and the transmission roller 69 can improve the stability of the blanking slide 622 in the up and down displacement at the bottom of the positioning guide seat 61. A circulating slide shaft 623 is fixedly provided at the center of the inner end surface of the fixed shaft sleeve 624, and a first blanking baffle 625 is provided at the lower end surface of the blanking slide 622 near the fixed shaft sleeve 624.

[0070] like Figure 14 The guide device 7 includes an alignment slide 71 for support, and a linear slide 72 for guiding is provided on the side end surface of the alignment slide 71, and a guide rail 73 is provided on the inner end surface of the alignment slide 71. The guide rail 73 is composed of an upper and lower vertical groove and an inclined groove connecting the two sets of vertical grooves. The upper and lower vertical grooves can provide sufficient time for the loading and stamping of the material guide device 2. A supporting slide rail 74 is fixedly provided at the center of the front end surface of the alignment slide 71.

[0071] like Figure 15 and Figure 16 The direction adjustment device 8 includes a connecting swivel seat 84, the inner end surface of the connecting swivel seat 84 is rotatably engaged with the limiting turntable 83, and a fourth synchronous pulley 81 is fixedly provided at the center of the rear end surface of the limiting turntable 83, and a guide card shaft 82 is provided near the outside of the front end surface of the limiting turntable 83.

[0072] like Figure 2 and Figure 7The pushing guide plate 242 is adapted to the guide slide 22 through the limit slider 241 and then slidably connected to the inside of the fixed slide 21. The guide slide 22 can provide a sufficient guiding basis for the pushing guide plate 242 through the limit slider 241, thereby improving the stability of the subsequent displacement of the pushing guide plate 242. The upper end surface of the pushing guide plate 242 is in contact with the bottom of the magazine unloading bin 23. When the pushing guide plate 242 is displaced to the rear limit, the rear wall of the shaping groove 246 is flush with the inner wall of the magazine unloading bin 23. When the pushing guide plate 242 is in the starting position, the rear wall of the shaping groove 246 is in contact with the inner wall of the magazine unloading bin 23, which can facilitate the subsequent magazine unloading bin 23 to directly guide the car door workpiece 1 to the inside of the shaping groove 246 to complete the loading. The depth of the shaping groove 246 is equal to the thickness of the car door workpiece 1, which can improve the accuracy of subsequent loading.

[0073] like Figure 7 、 Figure 14 and Figure 16 The fixed slide shaft 243 is adapted to the guide slide rail 73, and the guide card shaft 82 is adapted to the supporting slide rail 74. The direction adjustment device 8 is adapted to the supporting slide rail 74 through the guide card shaft 82, and the fixed slide shaft 243 is adapted to the guide slide rail 73, thereby driving the pushing guide plate 242 to cyclically move back and forth inside the fixed slide seat 21. The guide card shaft 82 can move in a circular sliding manner with the supporting slide rail 74, driving the supporting slide rail 74 to move up and down, thereby enabling the supporting slide rail 74 to drive the fixed slide shaft 243 and the loading device 24 to move back and forth through the guide slide rail 73, thereby improving the subsequent cyclic loading and guiding efficiency of the car door workpiece 1, the alignment slide groove 245 and the positioning card slot 25 are both slidably connected with the positioning card block 44, and the stamping die base 46 is slidably inserted into the positioning slot 247 through the positioning plug shaft 45, which can prevent the subsequent pushing guide plate 242 from moving during stamping, thereby improving the stability of stamping.

[0074] The opening width of the fixed slide rail 43 is equal to the diameter of the first guide shaft 52, and the guide turntable 53 is adapted to the fixed slide rail 43 through the first guide shaft 52, thereby driving the connecting slide 42 to slide and connect inside the fixed clamping plate 41. The first guide shaft 52 can limit the circumferential sliding with the fixed slide rail 43, and then cyclically drive the connecting slide 42 to move up and down inside the fixed clamping plate 41, thereby improving the stability of subsequent continuous stamping of the door workpiece 1. The first synchronous pulley 51 is meshed with the second synchronous pulley 65 through the first synchronous belt 9, and the third synchronous pulley 66 is meshed with the fourth synchronous pulley 81 through the second synchronous belt 12, which can effectively improve the stability and synchronization of the transmission inside the equipment.

[0075] The unloading slide 622 is adapted to the transmission roller 69 through the fixed shaft sleeve 624, and the circulating slide 623 is adapted to the circulating slide groove 68, and then slidably clamped inside the positioning guide seat 61. The unloading slide 622 and the first unloading baffle 625 can be cyclically displaced up and down inside the positioning guide seat 61 under the sliding limit of the circulating slide 623 and the circulating slide groove 68, thereby facilitating the subsequent cooperation with the stamping of the stamping device 4 to quickly and stably unload the car door workpiece 1 inside the guide device 2. The fixed slide groove 27 and the support guide groove 244 are both slidably connected to the first unloading baffle 625, which can effectively improve the convenience and stability of unloading the car door workpiece 1.

[0076] Working principle: Figure 5 Before stamping the door workpiece 1, the staff can stack multiple door workpieces 1 into the magazine unloading bin 23 through an external robotic arm, so that the subsequent magazine unloading bin 23 can circulate the loading operation of the processing equipment. When the door workpiece 1 is processed, Figure 2 At this time, the servo motor 13 can be directly started first, and the servo motor 13 can drive the reduction motor 11 to rotate. Figure 10 、 Figure 11 and Figure 15 , so that the reduction motor 11 can drive the first synchronous pulley 51 to rotate, and the first synchronous pulley 51 can synchronously drive the second synchronous pulley 65 to mesh and rotate through the first synchronous belt 9. At the same time, when the second synchronous pulley 65 rotates, it can synchronously drive the third synchronous pulley 66 at the rear to rotate, and the third synchronous pulley 66 can synchronously drive the fourth synchronous pulley 81 to mesh and rotate through the second synchronous belt 12;

[0077] like Figure 5 and Figure 15 When the door workpiece 1 is processed and cyclically loaded, the fourth synchronous pulley 81 can drive the limit turntable 83 and the guide card shaft 82 to rotate cyclically. At this time, the guide card shaft 82 can pass through the sliding limit with the support slide 74, and then drive the positioning slide 71 to cyclically move up and down inside the support slide 210. In the initial state, the guide card shaft 82 and the support slide 74 are at the bottom. At this time, the vertical groove at the top of the guide slide 73 can be pressed and limited with the guide card shaft 82, and the fixed slide 243 is at the rearmost starting position. Figure 5 and Figure 7At this time, the rear wall of the shaping slot 246 can fit with the rear wall of the magazine unloading bin 23, and the first group of door workpieces 1 at the bottom can fall into the shaping slot 246. At the same time, the upper end surface of the door workpiece 1 at the bottom is flush with the top of the pushing guide plate 242, which can prevent multiple groups of door workpieces 1 from falling together and affecting the loading. When the fourth synchronous pulley 81 rotates in a circle under the output power of the reduction motor 11, the guide card shaft 82 can drive the alignment slide 71 to move from the bottom to the top through the supporting slide rail 74, and the upper vertical groove can maintain the vertical sliding limit with the fixed slide shaft 243. The pushing guide plate 242 remains different, thereby providing sufficient guiding time for the car door workpiece 1 inside the magazine unloading bin 23 to fall into the shaping groove 246. When the car door workpiece 1 falls into the shaping groove 246, the inclined groove inside the guide slide rail 73 is slidably limited with the fixed slide shaft 243. When the inclined groove and the fixed slide shaft 243 are slid and pressed to limit, they can synchronously drive the fixed slide shaft 243 to move synchronously along the length direction of the inclined groove. At this time, the fixed slide shaft 243 can drive the pushing guide plate 242 and the car door workpiece 1 inside the shaping groove 246 to move synchronously toward the front to perform the loading operation;

[0078] like Figure 2 、 Figure 10 、 Figure 11 and Figure 13 When the above-mentioned shaping slot 246 drives the internal door workpiece 1 to move toward the blanking device 6 and the punching device 4, since the punching device 4, the blanking device 6 and the direction adjustment device 8 are synchronously driven, as shown in FIG. Figure 11 At this time, the third synchronous pulley 66 can drive the transmission roller 69 to rotate through the second synchronous pulley 65, the active bevel gear 64, and the driven bevel gear 63. At the same time, the transmission roller 69 can drive the limit device 62 to move from bottom to top through the circulating chute 68 when rotating. Figure 8 and Figure 10 At this time, the first guide shaft 52 is at the top, the first synchronous pulley 51 can be driven synchronously with the third synchronous pulley 66, the first synchronous pulley 51 can drive the first guide shaft 52 to move from the highest point to the bottom through the guide turntable 53, and the first guide shaft 52 can pass through the sliding limit with the fixed slide rail 43, thereby driving the entire stamping device 4 to move from the top to the bottom, as shown in FIG. Figure 1 and Figure 5 When the push guide plate 242 drives the door workpiece 1 to move to the bottom of the punching device 4, the fixed slide shaft 243 is just guided from the inclined groove to the lower vertical groove. At the same time, the punching die base 46 is positioned from top to bottom to the upper part of the door workpiece 1. At this time, the fixed slide shaft 243 is completely inserted into the lower vertical groove of the guide rail 73, and then remains motionless to provide sufficient time for punching. Figure 5 、 Figure 7 and Figure 9When the punching device 4 is positioned from top to bottom to the upper part of the car door workpiece 1 for punching, the four groups of positioning blocks 44 first contact the car door workpiece 1 through the bottom inclined surface. At the same time, the four groups of positioning blocks 44 can perform preliminary positioning of the car door workpiece 1 from all directions under the positioning of the positioning slide groove 245, so that the car door workpiece 1 remains aligned with the punching die seat 46. As the punching device 4 continues to move downward, the four groups of positioning plug shafts 45 can be positioned inside the positioning slot 247 for the second time, and then while positioning the car door workpiece 1 for the second time, the stability of the push guide plate 242 during punching is maintained. Then the punching die seat 46 can complete the punching operation of the car door workpiece 1. Figure 3 As shown, at this time, the fixed slide shaft 243 is displaced to the bottom of the vertical groove inside the guide rail 73, and the guide clamping shaft 82 is displaced to the top, and the above-mentioned limit device 62 that moves from bottom to top is also displaced to the top;

[0079] like Figure 2 、 Figure 5 、 Figure 8 and Figure 10 When the door workpiece 1 that has been stamped is unloaded, the fourth synchronous pulley 81 can drive the guide card shaft 82 to rotate from top to bottom through the limit turntable 83. At the same time, the guide card shaft 82 can drive the support slide rail 74 to move from top to bottom. At this time, the vertical groove at the bottom of the guide slide rail 73 continues to slide and limit with the fixed slide shaft 243, so that the stamping device 4 has enough time to release the limit of the door workpiece 1 and the material guide device 2. When the stamping device 4 is completely disengaged from the upward displacement, the inclined groove inside the guide slide rail 73 slides with the fixed slide shaft 243, so that the pushing guide plate 242 begins to retract and move backward. At the same time, Figure 12 and Figure 13 The limiting device 62 moves downward under the sliding limit of the circulating slide 68 and the circulating slide shaft 623. When the push guide plate 242 and the door workpiece 1 move to the position close to the limiting device 62, as shown in FIG. Figure 7 and Figure 13 At this time, the first unloading baffle 625 inside the limiting device 62 is first inserted into the supporting guide groove 244. As the pushing guide plate 242 continues to move backward, the first unloading baffle 625 continues to move downward until the first unloading baffle 625 blocks the door workpiece 1. At this time, the door workpiece 1 is gradually separated from the rearward-moving pushing guide plate 242 under the blocking of the first unloading baffle 625. When it is completely separated, the door workpiece 1 falls into the unloading chute 29 under the limit of the first unloading baffle 625, and then the stamped door workpiece 1 is discharged through the unloading guide plate 28. At the same time, the fixed slide shaft 243 is driven by the inclined groove in the guide slide rail 73 to move to the rear wall of the magazine unloading bin 23, and then the fixed slide shaft 243 is again limited by the top vertical groove of the guide slide rail 73, and then the magazine unloading bin 23 unloads the door workpiece 1 to the shaping slot 246 to complete the re-loading.

[0080] like Figure 17-18 This is the second embodiment of the present invention, which is different from the first embodiment in that a limiting groove 57 is provided at the center of the inner end surface of the guide turntable 53, and a stepper motor 56 is provided at the rear part of the inner end surface of the limiting groove 57, and a ball screw 54 is fixedly provided at the output end of the stepper motor 56. The inner end surface of the guide turntable 53 is connected to a ball slide 55 through a threaded sliding connection of the ball screw 54, and a first guide shaft 52 is fixedly provided at the center of the upper end surface of the ball slide 55.

[0081] Working principle: Before use, the user can adjust the overall stamping stroke of the stamping device 4 according to different models of car door workpieces 1. When adjusting, the staff can start the stepper motor 56. At this time, the stepper motor 56 can drive the ball screw 54 to rotate. At the same time, the ball screw 54 can drive the ball slide 55 and the first guide shaft 52 to perform centripetal and centrifugal displacement inside the guide turntable 53, thereby quickly and accurately adjusting the circumferential rotation radius of the first guide shaft 52, thereby adjusting the stroke of the first guide shaft 52 to drive the fixed slide rail 43 to perform up and down stamping, effectively improving the adaptability of the equipment to stamping different models of car door workpieces 1.

[0082] like Figure 19-20 This is the third embodiment of the present invention, which is different from the first embodiment in that: the inner end face of the unloading slide 622 is equidistantly slidably engaged with four groups of limiting guide rods 627, and the lower end faces of the four groups of limiting guide rods 627 are all provided with connecting pressure plates 6210, and the connecting pressure plates 6210 and the unloading slide 622 are elastically fixedly connected by four groups of return springs 629, a second unloading baffle 626 is provided near the rear of the lower end face of the connecting pressure plate 6210, and a fixed chamfer 628 is provided in front of the lower end face of the connecting pressure plate 6210.

[0083] Working principle: Before use, when unloading the stamped car door workpiece 1, the sliding limit of the limiting device 62 on the circulating slide shaft 623 and the circulating slide groove 68 can drive the connecting pressure plate 6210 to move downward, and the second unloading baffle 626 can first be positioned inside the support guide groove 244, and then the connecting pressure plate 6210 can be directly elastically pressed onto the upper end face of the pushing guide plate 242, so that the second unloading baffle 626 and the connecting pressure plate 6210 can respectively limit the rear and top of the car door workpiece 1 inside the shaping slot 246, effectively improving the accuracy and stability of the subsequent introduction of the car door workpiece 1 into the interior of the unloading guide plate 28, and at the same time, the fixed chamfer 628 can facilitate the quick and convenient introduction of the car door workpiece 1 into the bottom of the connecting pressure plate 6210, thereby improving the subsequent unloading efficiency of the car door workpiece 1.

[0084] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
