Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy processing, and more specifically to a multi-angle punching device for aluminum alloy processing. Background Art

[0002] Aluminum alloy punching is a metal processing technology that mainly applies pressure on aluminum alloy plates or pipes through a punch to cause the material to undergo plastic deformation and fracture in a local area, thereby forming the desired hole. The basic principle is to use the relative movement between the punch and the die to transfer the punch pressure to the aluminum alloy material. When the pressure exceeds the yield strength of the aluminum alloy material, the material begins to undergo plastic deformation. As the pressure continues to increase, the material eventually breaks and forms a hole. A punching device is required in the aluminum alloy punching process.

[0003] However, the existing punching devices have many defects in aluminum alloy punching processing. Among them, the burr problem is quite serious. There is no corresponding burr prevention measure. The hole mouth is easy to roll up and form burrs during punching, and it is difficult to control its outward diffusion, which makes the processed aluminum alloy plate hole edge burr cluster, which not only affects the appearance of the product, but also may scratch the operator or other parts in the subsequent use, reducing the quality and safety of the product, which is not conducive to improving the competitiveness of the product in the market.

[0023] Working method: When it is necessary to perform punching processing on the aluminum alloy plate, first place the aluminum alloy plate to be processed on a specific position of the workbench 1, and then start the clamping devices 2 on both sides of the workbench 1 to make them tightly clamp the aluminum alloy plate. Then, the linear drive device 3 starts to work, pushing the robot arm 4 to move along a predetermined path until the processing assembly 5 carried by the robot arm 4 is accurately positioned at the punching position above the aluminum alloy plate. At this time, the hydraulic rod 5021 in the processing assembly 5 is started to generate a strong thrust, driving the punching rod 5022 to move rapidly toward the surface of the aluminum alloy plate. The punching rod 5022 punches the required holes in the aluminum alloy plate with its sharp head and strong impact force. During the punching process, the two extrusion rings 503 located on both sides of the aluminum alloy plate support and fix the aluminum alloy plate, and the extrusion rings 503 are used to reduce the range of flanging deformation of the plate during the punching process.

[0024] The present invention achieves multi-angle punching of the aluminum alloy plate through close cooperation and coordinated work between various components during the processing process, and squeezes the outer area of ​​the punching point of the aluminum alloy plate through the extrusion ring 503 to prevent the plate hole from curling up and forming burrs that spread outward during punching. The present invention effectively improves the quality and accuracy of aluminum alloy punching processing through the provision of the extrusion ring 503, and solves the common plate deformation and burr problems in traditional punching processes.

[0025] Specifically, Figures 4 to 6As shown, the processing component 5 involved in the present invention also includes a clamping structure 504, which includes a first drive motor 5041, a rocker arm 5042, a connecting rod 5043, a slider 5044, a mounting frame 5045, and a slide groove 5046; the slide groove 5046 is arranged at the bottom end of the mounting frame 5045, the slider 5044 is slidably connected in the slide groove 5046, the connecting rod 5043 is rotatably connected to the bottom end of the slider 5044, the rocker arm 5042 is rotatably connected to the other end of the connecting rod 5043, the driving end of the first drive motor 5041 is installed at the top center of the rocker arm 5042, and the first drive motor 5041 is installed at the top of the mounting frame 5045.

[0026] Working method: When punching of the aluminum alloy plate is required, the clamping structure 504 in the processing assembly 5 works, the first drive motor 5041 receives the command to start, and its driving end drives the top center of the rocker arm 5042 to rotate, and the rocker arm 5042 performs a circular motion around the axis point connected to the first drive motor 5041, and the two ends of the rocker arm 5042 are rotatably connected to the two connecting rods 5043. As the rocker arm 5042 rotates, the connecting rod 5043 will be subjected to a pulling force or a thrust, thereby pushing the slider 5042 which is rotatably connected to the other end. 44. The slider 5044 slides in the slide groove 5046 at the bottom of the installation frame 5045. Due to the limiting effect of the slide groove 5046, the slider 5044 can only move along a predetermined straight line direction. Through the linkage cooperation of the rocker arm 5042, the connecting rod 5043 and the slider 5044, the slider 5044 can accurately approach or move away from the punching position, thereby realizing the clamping or loosening operation around the punching area of ​​the aluminum alloy plate. When the slider 5044 approaches, it can drive the extrusion ring 503 to further fix the aluminum alloy plate.

[0027] The present invention can drive the extrusion ring 503 to clamp the aluminum alloy plate through the clamping structure 504, thereby preventing the aluminum alloy plate from producing a small displacement or vibration due to force during the punching process, ensuring the accuracy and quality of the punching. The design of this clamping structure 504, through the ingenious mechanical connection and coordinated movement between the components, closely cooperates with other parts of the entire punching device, further improving the stability and reliability of the aluminum alloy plate processing. The present invention further avoids the problems of punching deviation and increased burrs caused by loose plates, and improves the quality of processed products.

[0028] It is worth noting that if Figures 7 and 8 As shown, the processing assembly 5 of the present invention further includes a flanging rolling assembly 505, and the flanging rolling assembly 505 includes a mounting frame 5051, a second driving motor 5052, a first transmission wheel 5053, a first transmission belt 5054, a transmission shaft 5055, a driving wheel 5056, a driving ring 5057, a first cylinder 5058, and a rolling wheel 5059; The rolling wheel 5059 is installed on the driving end of the first cylinder 5058, and the six first cylinders 5058 are equidistantly installed in a ring on one side of the driving ring 5057. The driving ring 5057 is rotatably connected to the inner side of the three driving wheels 5056, and the three driving wheels 5056 are equidistantly arranged in a ring. The driving wheels 5056 are installed on the transmission shaft 5055, and the other end of the transmission shaft 5055 is installed on the first transmission wheel 5053. The first transmission wheel 5053 is connected to another first transmission wheel 5053 through a first transmission belt 5054. The other first transmission wheel 5053 is installed on the driving end of the second driving motor 5052.

[0030] An arc groove is provided on one side of the rolling wheel 5059 , and an arc surface is provided at the connection between the arc groove and the side surface of the rolling wheel 5059 .

[0031] Working method: When the aluminum alloy plate completes the punching operation, the flanging roller assembly 505 is immediately started to process the edge of the hole after punching. First, the second drive motor 5052 starts to operate after receiving the working signal, and its driving end drives the first transmission wheel 5053 connected to it to rotate. The first transmission wheel 5053 transmits power to another first transmission wheel 5053 through the first transmission belt 5054, thereby driving the transmission shaft 5055 to rotate. The three driving wheels 5056 installed on the transmission shaft 5055 rotate synchronously with the transmission shaft 5055. Since both sides of the driving wheel 5056 are provided with convex edges, and these convex edges are connected to the outer surface of the driving ring 5057 The concave annular groove on the side is slidably connected, so when the driving wheel 5056 rotates, it will drive the driving ring 5057 to rotate stably on its inner side; during the rotation of the driving ring 5057, the six equidistant annularly arranged first cylinders 5058 installed on one side of the driving ring 5057 also move accordingly, and the rolling wheel 5059 at the driving end of the first cylinder 5058 is brought to the hole edge position after punching, and an arc groove is provided on one side of the rolling wheel 5059, and an arc surface is provided at the connection between the arc groove and the side of the rolling wheel 5059, so that the hole edge is evenly and effectively rolled. The first cylinder 5058 can adjust the position and pressure of the rolling wheel 5059 according to actual processing requirements.

[0032] The present invention cooperates with other parts of the entire processing assembly 5 through the flanging rolling assembly 505, and provides arc grooves and arc surfaces on the rolling wheel 5059. This design enables the rolling wheel 5059 to better fit the shape of the hole when contacting the hole edge, and performs uniform and effective rolling operation on the hole edge, while ensuring that the hole edge is properly rolled, so that the hole edge after punching forms a smooth and regular flanging shape. The present invention can perform high-quality flanging processing on the hole edge in time after punching, thereby improving the overall quality and aesthetics of the aluminum alloy plate after processing.

[0033] Further, such as Figures 9 and 10 As shown, the processing assembly 5 of the present invention further includes an inner ring rolling assembly 506, and the inner ring rolling assembly 506 includes a third driving motor 5061, a mounting plate 5062, a guide arm 5063, a guide rod 5064, an unfolding arm 5065, a rolling rod 5066, a follower gear 5067, a guide groove 5068, a driving gear 5069, and a fourth driving motor 50610; The fourth driving motor 50610 is installed on the guide arm 5063, the driving gear 5069 is installed on the driving end of the fourth driving motor 50610, the follower gear 5067 is meshed and connected to the driving gear 5069, the rolling rod 5066 is rotatably connected to the unfolding arm 5065, the other end of the unfolding arm 5065 is installed on the guide rod 5064, the guide rod 5064 is slidably connected in the guide groove 5068, five guide grooves 5068 are equidistantly arranged in a ring on the follower gear 5067, the guide rod 5064 is slidably connected in the guide arm 5063, the five guide arms 5063 are equidistantly installed in a ring on the mounting plate 5062, the mounting plate 5062 is installed on the driving end of the third driving motor 5061, and the follower gear 5067 is rotatably connected to the mounting plate 5062.

[0034] A recessed portion is provided in the middle of the roller rod 5066, and an arc surface is provided at the edge of the recessed portion.

[0035] Working method: After the flanging and rolling processing of the aluminum alloy plate is completed, the inner ring needs to be rolled, and the inner ring rolling component 506 starts to operate. First, the mechanical arm 4 drives the inner ring rolling component 506 to move into the punching hole of the aluminum alloy plate, and the fourth driving motor 50610 starts to work, and the driving gear 5069 at its driving end rotates. Since the follower gear 5067 is meshed and connected with the driving gear 5069, the follower gear 5067 will also rotate accordingly. The five guide grooves 5068 equidistantly arranged in an annular shape on the follower gear 5067 guide the guide rod 5064 slidably connected thereto to move. The guide rod 5064 moves along a specific trajectory under the constraint of the guide groove 5068. At the same time, the guide rod 5064 moves along the guide arm 5 063 also slides inside, so that the guide rod 5064 moves outward along the guide arm 5063; as the guide rod 5064 moves, the unfolding arm 5065 installed at the other end thereof will also change position, thereby driving the rolling rod 5066 to approach the inner ring of the punching hole of the aluminum alloy plate. When the rolling rod 5066 contacts the inner ring of the punching hole, the third drive motor 5061 starts, driving the mounting plate 5062 to rotate, and the third drive motor 5061 and the fourth drive motor 50610 work together. The rotation of the mounting plate 5062 cooperates with the position adjustment of the rolling rod 5066, so that the rolling rod 5066 can perform a rolling and pressing operation along the circumferential direction of the inner ring of the punching hole, and evenly press the inner ring of the punching hole of the aluminum alloy plate.

[0036] The present invention further rolls the aluminum alloy plate stamping after flanging rolling through the inner ring rolling assembly 506, and at the same time, a recessed portion is provided in the middle of the rolling rod 5066, and a circular arc surface is provided at the edge of the recessed portion. This special structural design enables the rolling rod 5066 to closely fit the shape of the punched inner ring when contacting the punched inner ring, and the transition of the circular arc surface avoids scratching or damage to the inner ring during the rolling process. The present invention can effectively improve the surface quality of the inner ring, further eliminate burrs and uneven defects that may be generated during the punching process, and make the punched inner ring smoother and more regular.

[0037] Further, if Fig.11As shown, the processing assembly 5 involved in the present invention also includes a stamping and trimming assembly 507, which includes a stamping rod 5071, a driving rod 5072, a screw sleeve 5073, a screw 5074, a second transmission wheel 5075, a second transmission belt 5076, a fifth driving motor 5077, and a connecting sleeve 5078; both sides of the connecting sleeve 5078 are rotatably connected to the two screws 5074 respectively, the fifth driving motor 5077 is installed on the mounting plate 501, the second transmission wheel 5075 is installed on the driving end of the fifth driving motor 5077, the second transmission wheel 5075 is transmission-connected to another second transmission wheel 5075 through the second transmission belt 5076, the other transmission wheel is installed on the other end of the screw 5074, the screw 5074 is threadedly connected to the inner side of the screw sleeve 5073, the screw sleeve 5073 is installed on the driving rod 5072, and the other end of the driving rod 5072 is installed on the stamping rod 5071.

[0038] The stamping and trimming assembly 507 also includes a third transmission wheel 5079, a third transmission belt 50710, and a sixth drive motor 50711; the sixth drive motor 50711 is installed on the mounting frame 5051, the third transmission wheel 5079 is installed on the driving end of the sixth drive motor 50711, the third transmission wheel 5079 is connected to another third transmission wheel 5079 through the third transmission belt 50710, and the other third transmission wheel 5079 is installed on the connecting sleeve 5078.

[0039] The stamping and trimming assembly 507 further includes a limiting guide rod 50712 , and two ends of the limiting guide rod 50712 are respectively slidably connected to the two screw sleeves 5073 .

[0040] Working method: After the inner ring rolling operation of the aluminum alloy plate is completed, the hole edge needs to be stamped and trimmed, and the stamping and trimming component 507 is put into operation. First, the sixth drive motor 50711 installed on the mounting frame 5051 starts to operate, and the third transmission wheel 5079 at its driving end drives another third transmission wheel 5079 installed on the connecting sleeve 5078 to rotate through the third transmission belt 50710, so that the connecting sleeve 5078 starts to rotate, and the connecting sleeve 5078 drives the punching rod 5071 to rotate along the screw 5074 through the screw 5074, so that the punching rod 5071 moves to the top of the extrusion ring 503, and then the fifth drive motor 5077 is started, and its driving end drives the second transmission wheel 5075 to rotate, and transmits power to another second transmission wheel 5075 through the second transmission belt 5076, so that the screw 5074 starts Rotation, since the screw rod 5074 is threadedly connected with the screw sleeve 5073, the screw sleeve 5073 will move along the axial direction of the screw rod 5074 when the screw rod 5074 rotates, and the driving rod 5072 installed on the screw sleeve 5073 will drive the punching rod 5071 to approach the punching edge of the aluminum alloy plate as the screw sleeve 5073 moves. In the process of the punching rod 5071 approaching the punching edge, the limiting guide rod 50712 plays a key guiding and stabilizing role. The two ends of the limiting guide rod 50712 are respectively slidably connected to the two screw sleeves 5073, which limits the freedom of the screw sleeve 5073, so that the screw sleeve 5073 can only move in a straight line along the direction of the limiting guide rod 50712, preventing the screw sleeve 5073 from deviating or shaking when the screw rod 5074 rotates, thereby ensuring that the punching rod 5071 can be accurately positioned at the punching edge for punching and trimming operations.

[0041] The present invention drives the punching rod 5071 to work through the punching edge finishing structure, and the punching rod 5071 can effectively squeeze the metal material at the edge of the punching hole inward, and the hole edge after the punching edge finishing process has a more compact and regular structure. This regular hole edge structure can not only improve the strength and stability of the aluminum alloy plate itself, but also better cooperate with other parts in the subsequent assembly process.
