Description

Technical Field

[0002] The automatic punching device for processing metal three-dimensional signs is an efficient and precise automated equipment designed specifically for metal signs. It uses CNC technology to achieve automatic positioning, efficient punching and intelligent chip removal. The device is an automated equipment that integrates mechanical transmission, intelligent control and pneumatic punching technology. It is mainly used to process circular, square or customized holes on metal three-dimensional signs. It uses computer programming to set the hole coordinates, hole size and processing path, replacing traditional manual punching and significantly improving processing efficiency and accuracy.

[0003] However, the conventional device still has the following problems when used:

[0004] The patent application publication number is CN216370268U, which discloses a punching device for processing home appliance signs.

DETAILED DESCRIPTION

[0034] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For example, see Figures 1 to 13The present invention provides a technical solution for an automatic punching device for processing metal three-dimensional signs: it includes a punching device body 1, a punching mechanism 11 is arranged on the punching device body 1, the outer wall at the bottom of the punching mechanism 11 is fixedly connected to a shell body 2, the outer wall at the bottom of the punching mechanism 11 is fixedly connected to an output end 12, the outer wall at the bottom of the output end 12 is fixedly connected to a rotating rod 21, a connecting hole 13 is opened on the outer wall at the bottom of the rotating rod 21, the outer wall of the rotating rod 21 is fixedly connected to a main gear 22, the outer wall of the rotating rod 21 is rotatably connected to the lower part of the shell 2, and a speed-up mechanism is arranged inside the shell 2, the speed-up mechanism includes a mounting seat 25, a sub-gear 24 and a transmission belt 26, and the inner wall of the transmission belt 26 is meshed and connected with the outer wall of the main gear 22.

[0036] By calculating the distance between the two drill bits 5 when moving the mounting base 25, when the distance between the two drill bits 5 reaches the position where the holes in the appliance sign need to be punched, the movement of the drill bits 5 can be stopped, so that the two drill bits 5 can punch holes in the appliance sign at the same time, thereby avoiding the time consumed by a single drill bit 5 to drill holes in the four corners of the appliance sign in turn, thereby correspondingly reducing the efficiency of punching holes in the appliance sign.

[0037] Embodiment 2, on the basis of embodiment 1, a slide groove 27 is provided at the lower part of the interior of the shell 2, the interior of the slide groove 27 is rotatably connected to the outer wall of the bottom of the transmission belt 26, a slide groove 28 is provided inside the shell 2, the interior of the slide groove 28 is located on both sides of the rotating rod 21 and is slidably connected with mounting plates 23, the interiors of the two mounting plates 23 are rotatably connected with mounting seats 25, the outer wall of the mounting seats 25 is fixedly connected with a sub-gear 24, the inner wall of the bottom of the mounting seat 25 is threadedly connected with a drill bit 5, and the outer wall of the sub-gear 24 is slidably connected to the inner wall of the transmission belt 26.

[0038] Through the movement of the transmission belt 26, the two sub-gears 24 can be driven to rotate simultaneously, and then through the rotation of the sub-gear 24, the mounting seat 25 can drive the drill bit 5 to work, so that the two drill bits 5 can process the home appliance sign at the same time, avoiding the need to frequently adjust the position of the drill bit 5 or the home appliance sign in the process of a single drill bit 5 drilling holes in the four corners of the home appliance sign in turn, and correspondingly reducing the time for adjusting the drill bit 5, further improving the working effect of the drill bit 5. At the same time, because the two drill bits 5 work at the same time, the drilling position and depth parameters of the home appliance sign can be consistently controlled, which not only improves product quality, but also reduces the scrap rate caused by processing errors.

[0039] Embodiment 3, on the basis of embodiment 2, the inner wall of the shell 2 is fixedly connected with a connecting rod 42, the outer wall of the connecting rod 42 is rotatably connected with a pressure roller 43, the inner wall of the shell 2 is located above the connecting rod 42 and is fixedly connected with a solution tank 4, the outer wall of the bottom of the solution tank 4 is fixedly connected with a feed pipe 41, a circulation hole is opened inside the connecting rod 42, and absorbent cotton 44 is fixedly connected inside the pressure roller 43, and the outer wall of one end of the absorbent cotton 44 is in contact with the outer wall of the circulation hole.

[0040] By the outer wall of the pressure roller 43 contacting the top of the transmission belt 26, the upper part of the transmission belt 26 can be pressed, so as to prevent the transmission belt 26 from slipping out of the inner part of the slide groove 27 during operation, and correspondingly increase the stability of the transmission belt 26 during operation. Since the pressure roller 43 and the connecting rod 42 are rotatably connected, when the pressure roller 43 contacts the transmission belt 26, the friction between the transmission belt 26 and the pressure roller 43 drives the pressure roller 43 to rotate. The rotating pressure roller 43 can reduce the resistance to the transmission belt 26, so that the transmission belt 26 is smoother during movement.

[0041] When the transmission belt 26 contacts the sub-gear 24 and the main gear 22, the lubricating fluid can be transferred to the sub-gear 24 and the main gear 22, thereby maintaining the sub-gear 24 and the main gear 22, avoiding the outer walls of the sub-gear 24 and the main gear 22 being relatively dry during long-term work and affecting the work efficiency, and correspondingly increasing the working stability of the main gear 22 and the sub-gear 24 and reducing the wear on the main gear 22 and the sub-gear 24.

[0042] Embodiment 4, on the basis of embodiment 1, the outer wall of the bottom of the shell 2 is located below the slide groove 28 and is provided with a slide groove 3 6, the outer wall of the bottom of the slide groove 3 6 is fixedly connected with a marking scale 61, grooves 1 69 are provided on both sides of the mounting plate 23, a plug hole 68 is provided at the bottom inside the groove 1 69, a return spring 3 67 is fixedly connected to the top inside the groove 1 69, a push plate 66 is rotatably connected to the outer wall of the bottom of the return spring 3 67, a fixed rod 62 is fixedly connected to the middle position of the outer wall at the bottom of the push plate 66, the outer wall of the bottom of the push plate 66 is located on both sides of the fixed rod 62 and is fixedly connected with an insertion rod 65, the outer wall of the insertion rod 65 is movably plugged into the inside of the plug hole 68, the inside of the fixed rod 62 is movably fixedly connected with a return spring 1 64 on both sides, the outer wall of the opposite side of the two return springs 1 64 is fixedly connected with a movable plate 63, the outer wall of the movable plate 63 is slidably connected to the inside of the fixed rod 62, and the outer wall of the movable plate 63 is movably in contact with the inner wall of the slide groove 3 6.

[0043] By removing the insertion rod 65 from the insertion hole 68, the limit on the fixed rod 62 is released. Through the cooperation of the insertion rod 65 and the insertion hole 68, when the moving plate 63 is working, rotation is avoided, which affects the effect of the moving plate 63 limiting the mounting plate 23. Correspondingly, by fixing the mounting plate 23, the mounting plate 23 can better limit the mounting seat 25, thereby increasing the stability of fixing the mounting seat 25.

[0044] By squeezing the narrower area inside the third chute 6 with the moving plate 63, the moving plate 63 enters the inside of the fixed rod 62, facilitating the sliding of the fixed rod 62 inside the third chute 6. It is avoided that the radius of the fixed rod 62 is always the same as the wider area inside the third chute 6, which affects the sliding effect of the fixed rod 62 inside the third chute 6. Correspondingly, by adjusting the state of the fixed rod 62, the fixed rod 62 can adapt to different widths of the area inside the third chute 6, thereby improving the flexibility of the fixed rod 62 sliding inside the third chute 6. Since the fixed rod 62 is always inside the third chute 6, it is convenient to fix the mounting seat 25 when it stops moving, preventing unnecessary displacement of the mounting seat 25 due to external vibration or other factors.

[0045] Embodiment Five: On the basis of Embodiment Two, on the outer walls on both sides of the mounting seat 25, a second reset spring 52 is fixedly connected below the mounting plate 23. A T-shaped pull plate 51 is movably sleeved inside the second reset spring 52. One end of the outer wall of the T-shaped pull plate 51 is movably inserted into the inside of the mounting seat 25. A fixing hole 53 is formed on the outer wall of the drill bit 5, and one end of the outer wall of the T-shaped pull plate 51 is movably inserted into the inside of the fixing hole 53.

[0046] After the drill bit 5 is threadedly connected to the mounting seat 25, the T-shaped pull plate 51 can be inserted into the inside of the fixing hole 53. Under the action of the second reset spring 52, the T-shaped pull plate 51 can be fixed inside the fixing hole 53, avoiding the drill bit 5 falling off the mounting seat 25 during work. Correspondingly, through the cooperation of the T-shaped pull plate 51 and the fixing hole 53, the drill bit 5 can be fixed inside the mounting seat 25, preventing the drill bit 5 from rotating inside the mounting seat 25 during work, thereby increasing the stability of the drill bit 5.

[0047] Embodiment Six: On the basis of Embodiment Two, a fourth chute 7 is formed inside the housing 2 above the second chute 28. A second groove 73 is formed on the outer wall of the top of the mounting plate 23. A buffer spring 72 is fixedly connected inside the second groove 73. A sliding plate 71 is fixedly connected to the outer wall of the top of the buffer spring 72. The outer wall of the sliding plate 71 is slidably connected to the inside of the fourth chute 7. A telescopic block 74 is fixedly connected to the middle position at the bottom of the sliding plate 71. The outer wall of the bottom of the telescopic block 74 is fixedly connected to the outer wall of the top of the mounting plate 23.

[0048] Through the action of the buffer spring 72, buffer protection can be provided for the drill bit 5 and the mounting plate 23 at the same time, reducing the risk of damage to the two due to impact force or vibration during the processing, not only extending the service life of the drill bit 5, but also ensuring the structural stability of the mounting plate 23. The buffering effect can effectively reduce the vibration amplitude when the drill bit 5 contacts the home appliance sign, thereby ensuring that the drilling operation is smoother and more precise. At the same time, the stability of the mounting plate 23 is also guaranteed, preventing processing errors caused by vibration or displacement, and correspondingly improving the overall work efficiency.

[0049] Embodiment 7, on the basis of embodiment 2, a cavity 32 is opened inside the drill bit 5, a dust inlet hole 31 is opened below the outer wall of the drill bit 5, the outer wall of the dust inlet hole 31 is connected through the outer wall of the cavity 32, the outer wall of the cavity 32 is connected through the interior of the mounting seat 25, the outer wall of the top of the mounting seat 25 is fixedly connected with the telescopic dust suction tube 3, and the outer wall of the telescopic dust suction tube 3 is connected through the outer wall of the top of the shell 2 in a sliding manner.

[0050] By connecting the telescopic dust suction tube 3 to the dust suction system, when the drill bit 5 processes the appliance sign, the generated debris will be sucked in through the dust inlet hole 31 provided on the drill bit 5, and will enter the telescopic dust suction tube 3 through the cavity 32 and be discharged, thereby preventing the debris from being scattered around the workbench or equipment, thereby keeping the processing environment clean and tidy, reducing the cleaning workload, and ensuring that the drill bit 5 is always in an ideal working condition by cleaning the debris in time.

[0051] The working principle and use process of the present invention are as follows: during operation, first, when punching holes in home appliance labels, home appliance labels of the same model are arranged and placed together. The operator pushes the fixing rod 62 upward by hand, and then the fixing rod 62 moves, so that the fixing rod 62 can push the push plate 66 to move upward inside the groove 69. Then, through the connection between the push plate 66 and the insertion rod 65, the insertion rod 65 can be driven out of the insertion hole 68 while the push plate 66 moves upward, thereby releasing the limit on the fixing rod 62. Through the cooperation between the insertion rod 65 and the insertion hole 68, the rotation of the movable plate 63 during operation that affects the limit effect of the movable plate 63 on the mounting plate 23 is avoided. Accordingly, by fixing the mounting plate 23, the mounting plate 23 can better limit the mounting seat 25, thereby increasing the stability of the fixation of the mounting seat 25.

[0052] After releasing the limit of the fixed rod 62, the operator rotates the fixed rod 62 by hand, and then rotates the fixed rod 62 by 90 degrees, which can drive the push plate 66 and the movable plate 63 to rotate at the same time. When the outer wall of the movable plate 63 rotates to a position that contacts the narrower inner wall of the slide groove 3 6, the rotation of the fixed rod 62 can be stopped. At this time, when the operator moves the mounting seat 25, the mounting seat 25 drives the fixed rod 62 to move inside the slide groove 3 6, so that the narrower area inside the slide groove 3 6 can be squeezed with the movable plate 63, so that the movable plate 63 enters the interior of the fixed rod 62, which is convenient for fixing. The fixed rod 62 slides inside the slide groove three 6, which avoids the radius of the fixed rod 62 always being the same as the wider area inside the slide groove three 6, affecting the sliding effect of the fixed rod 62 inside the slide groove three 6. By adjusting the state of the fixed rod 62 accordingly, the fixed rod 62 can adapt to the areas of different widths inside the slide groove three 6, thereby improving the sliding flexibility of the fixed rod 62 inside the slide groove three 6. By keeping the fixed rod 62 inside the slide groove three 6, it is convenient to fix the mounting seat 25 when it stops moving, thereby preventing the mounting seat 25 from unnecessary displacement due to external vibration or other factors.

[0053] It should be noted that: under the action of the reset spring 3 67, the insertion rod 65 can be inserted into the inside of the insertion hole 68 again after the fixed rod 62 has rotated, preventing the fixed rod 62 from rotating due to the friction force when the fixed rod 62 moves, thereby increasing the stability of the fixed rod 62.

[0054] After the state adjustment of the fixing rod 62 is completed, the operator pushes the mounting seat 25 by hand. When the mounting seat 25 is subjected to force movement, the mounting plate 23 and the drill bit 5 can be driven to slide inside the second slide groove 28 at the same time. The setting of the marking scale 61 facilitates the calculation of the distance between the two drill bits 5 when operating the moving mounting seat 25. When the distance between the two drill bits 5 is the position where the holes in the home appliance sign need to be punched, the movement of the drill bits 5 can be stopped, so that the two drill bits 5 can punch holes in the home appliance sign at the same time, thereby avoiding a single drill bit 5 drilling holes in the four corners of the home appliance sign in turn, which consumes a long time and correspondingly reduces the efficiency of punching holes in the home appliance sign.

[0055] It works by starting the punching mechanism 11. Subsequently, through the movement of the punching mechanism 11, the output end 12 drives the rotating rod 21 to rotate accordingly. Then, through the fixed connection between the rotating rod 21 and the main gear 22, the main gear 22 can be driven to move while the rotating rod 21 rotates. Through the meshing connection between the main gear 22 and the transmission belt 26, the transmission belt 26 can be driven to rotate inside the first chute 27 while the main gear 22 rotates. Subsequently, through the movement of the transmission belt 26, the two sub-gears 24 can be driven to rotate simultaneously. Then, through the rotation of the sub-gears 24, the mounting seat 25 can drive the drill bit 5 to work, so that the two drill bits 5 process the home appliance nameplate simultaneously, avoiding the need to frequently adjust the position of the drill bit 5 or the home appliance nameplate during the process of a single drill bit 5 drilling the four corners of the home appliance nameplate in sequence, correspondingly reducing the time for adjusting the drill bit 5, further improving the working effect of the drill bit 5. At the same time, since the two drill bits 5 work simultaneously, the drilling position and depth parameters of the home appliance nameplate can be controlled consistently, not only improving the product quality but also reducing the rejection rate caused by processing errors.

[0056] Furthermore, through the connecting rod 42 and the pressure roller 43 arranged inside the housing 2, and then through the contact between the outer wall of the pressure roller 43 and the top of the transmission belt 26, the upper part of the transmission belt 26 can be pressed, avoiding the transmission belt 26 slipping out of the first chute 27 during work, correspondingly increasing the stability of the transmission belt 26 during work. Since the pressure roller 43 is rotatably connected to the connecting rod 42, when the pressure roller 43 contacts the transmission belt 26, the frictional force between the transmission belt 26 and the pressure roller 43 can drive the pressure roller 43 to rotate. The rotating pressure roller 43 can reduce the resistance to the transmission belt 26, making the transmission belt 26 move more smoothly during the movement process.

[0057] Furthermore, through the flow channel opened inside the connecting rod 42, the lubricating fluid in the solution tank 4 can be transferred to the inside of the connecting rod 42 through the function of the feeding pipe 41. Through the setting of the absorbent cotton 44, the lubricating fluid entering the inside of the connecting rod 42 can be absorbed. Then, through the edge of the absorbent cotton 44 that is higher than the pressure roller 43, when the pressure roller 43 drives the absorbent cotton 44 to rotate and contact the transmission belt 26, due to the extrusion effect between the two, the absorbent cotton 44 deforms, and the lubricating fluid is extruded from the inside of the absorbent cotton 44 during the deformation process, thus entering the inside of the teeth through the top of the transmission belt 26. When the transmission belt 26 contacts the sub-gear 24 and the main gear 22, the lubricating fluid can be transferred to the sub-gear 24 and the main gear 22, thereby maintaining the sub-gear 24 and the main gear 22, avoiding the outer walls of the sub-gear 24 and the main gear 22 being too dry during long-term work and affecting the work efficiency, correspondingly increasing the working stability of the main gear 22 and the sub-gear 24, and reducing the wear of the main gear 22 and the sub-gear 24.

[0058] By connecting the telescopic dust suction pipe 3 to the dust suction system, when the drill bit 5 processes the household appliance nameplate, the generated debris will be sucked in through the dust inlet hole 31 opened on the drill bit 5, enter the telescopic dust suction pipe 3 through the inside of the cavity 32 and be discharged, avoiding the debris from scattering on the workbench or around the equipment. Correspondingly, the processing environment is kept clean, the cleaning workload is reduced, and by cleaning the debris in time, it is ensured that the drill bit 5 is always in an ideal working condition.

[0059] Through the buffer spring 72 provided on the mounting plate 23, under the action of the buffer spring 72, it can provide buffer protection for both the drill bit 5 and the mounting plate 23 at the same time, reducing the risk of damage to both of them caused by impact force or vibration during the processing. It not only extends the service life of the drill bit 5, but also ensures the structural stability of the mounting plate 23. The buffering effect can effectively reduce the vibration amplitude when the drill bit 5 contacts the household appliance nameplate, thus ensuring that the drilling operation is more stable and precise. At the same time, the stability of the mounting plate 23 is also guaranteed, preventing processing errors caused by vibration or displacement, and correspondingly improving the overall working efficiency.

[0060] Through the sliding connection between the sliding plate 71 and the fourth chute 7, when the mounting plate 23 moves, the sliding plate 71 can slide inside the fourth chute 7. Then, through the setting of the telescopic block 74, a supporting effect can be started on the sliding plate 71 when the sliding plate 71 moves, avoiding that when the sliding plate 71 slides inside the fourth chute 7, due to the friction between the sliding plate 71 and the fourth chute 7, the movement of the sliding plate 71 is out of sync with that of the mounting plate 23, causing the sliding plate 71 to deviate from the middle position of the mounting plate 23. Correspondingly, with the action of the keel telescopic block 74, it is prevented that the sliding plate 71 will deviate from the middle position of the mounting plate 23 during movement, so that the sliding plate 71 is always in the middle of the mounting plate 23, and the buffer spring 72 can always be kept in a vertical state.

[0061] It should be noted that: a damping structure is provided inside the buffer spring 72.

[0062] After the drill bit 5 is threadedly connected to the mounting seat 25, the T-shaped pull plate 51 can be inserted into the fixing hole 53. Under the action of the second return spring 52, the T-shaped pull plate 51 can be fixed inside the fixing hole 53, avoiding that the drill bit 5 will fall off from the mounting seat 25 during work. Correspondingly, through the cooperation of the T-shaped pull plate 51 and the fixing hole 53, the drill bit 5 can be fixed inside the mounting seat 25, preventing the drill bit 5 from rotating inside the mounting seat 25 during work, thereby increasing the stability of the drill bit 5.

[0063] It should be noted that: when only one drill bit 5 needs to be used for work, only the drill bit 5 needs to be connected to the connection hole 13 for use.

[0064] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
