Description

[0001] The invention relates to the technical field of electrical connection device processing, in particular to a copper nose stamping processing device. Background Art

[0002] Copper lugs, a common electrical connector, are widely used in fields such as electricity, electronics, and communications. Their primary function is to connect cables to equipment through crimping or welding, ensuring stable current transmission. The rapid development of industrial automation has placed higher demands on the production efficiency and processing precision of copper lugs. Traditional copper lug processing methods rely heavily on manual operation or semi-automated equipment, resulting in low production efficiency, unstable processing precision, and significant material waste, making them difficult to meet the large-scale, high-quality production needs of modern industry.

DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0048] Example 1

[0049] See also Figure 1-Figure 3 A copper nose stamping processing equipment includes a workbench 1 and a combined stamping component 2, a vibrating loader 3, a transfer robot arm 4, and a forming component 5 assembled on the workbench 1 and maintained in a matching combination.

[0050] The combined stamping assembly 2 is used to stamp the material sheet 61 to form a sheet 62, the vibration loader 3 is used to receive the sheet 62 output by the combined stamping assembly 2 and transport it to the forming loading assembly, the forming assembly 5 is used to process the sheet 62 to form a finished part 63, and the transfer robot 4 is used to clamp and transfer the sheet 62 or the finished part 63.

[0051] The combined stamping assembly 2 includes an assembly platform 21, a support platform 22, a lifting platform 23, a stamping seat 24, and a cushion seat 25. The support platform 22 is fixedly installed on the assembly platform 21, and the lifting platform 23 is slidably installed on the support platform 22 and moves up and down in the vertical direction. The stamping seat 24 and the cushion seat 25 are respectively rotatably installed on the lifting platform 23 and the assembly platform 21. The axes of the stamping seat 24 and the cushion seat 25 are arranged in the same vertical direction. A stamping head 241 is fixedly connected to the bottom of the stamping seat 24, and a stamping hole 251 is opened on the cushion seat 25, which is nested and matched with the stamping head 241. The stamping head 241 and the stamping hole 251 are both consistent with the sheet 62.

[0052] The combined stamping assembly 2 also includes a hydraulic telescopic cylinder 26, a feeding assembly 27, a reversing assembly 28, and a transmission assembly 29. The hydraulic telescopic cylinder 26 is arranged in the vertical direction and is fixedly connected to the support platform 22 and the lifting platform 23. The feeding assembly 27 is assembled on the assembly platform 21 and arranged on both sides of the pad 25. The reversing assembly 28 is matched with the stamping seat 24 and the pad 25. The transmission assembly 29 maintains a linkage combination with the lifting platform 23, the feeding assembly 27, and the reversing assembly 28.

[0053] The workbench 1 can be horizontally mounted on the frame, thereby ensuring that the joint stamping assembly 2, the vibrating loader 3, the transfer robot arm 4, and the forming assembly 5 are stably combined thereon and realizing the matching combination between the components, thereby realizing efficient processing of the finished product 63 of the copper nose.

[0054] For the combined stamping assembly 2, the assembly platform 21 and the support platform 22 are fixedly combined to ensure that the remaining components are stably assembled and operated in the corresponding positions. With the help of the hydraulic telescopic cylinder 26, the lifting platform 23 can stably operate in a relative lifting manner on the support platform 22 to achieve reasonable adjustment of the distance between the stamping seat 24 and the cushion seat 25.

[0055] In the process of the lifting platform 23 driving the stamping seat 24 to rise, the feeding assembly 27 and the reversing assembly 28 can be driven to operate stably through the transmission assembly 29. When the feeding assembly 27 is running, the material plate 61 in the feeding assembly 27 can be stably transported forward to push out the part of the material sheet 62 that has been stamped, and push the new continuous material plate 61 between the stamping head 241 and the stamping hole 251.

[0056] Since the blank 62 has a T-shaped structure, in order to fully utilize the blank 61, the blank 62 punched out on the blank 61 next time is arranged in the opposite direction of the blank 62 punched out on the blank 61, which can maximize the material and reduce the generation of scrap. Therefore, when the reversing assembly 28 is in operation, it can drive the punching seat 24, the pad 25, and the punching head 241 and punching hole 251 respectively provided thereon to rotate synchronously by 180 degrees to achieve the reversal of the punched blank 62.

[0057] When the lifting platform 23 is driven to descend by the hydraulic telescopic cylinder 26, the punch head 241 can cooperate with the punch hole 251 to cut the sheet 62 from the sheet 61 between them. The sheet 62 finally falls through the bottom of the punch hole 251 and into the vibrating feeder 3. During this process, the transmission assembly 29 is in a disconnected state, and the descending lifting platform 23 cannot transmit power to the reversing assembly 28 and the feeding assembly 27, so as to ensure that the reversing assembly 28 and the feeding assembly 27 are in a stationary state, thereby achieving stable punching of the sheet 62.

[0058] The vibrating loader 3 can arrange the collected sheets 62 neatly and transport them stably in the direction of the forming component 5. The sheet 62 transmitted from the vibrating loader 3 is transferred to the forming component 5 with the help of the transfer robot arm 4. The forming component 5 punches and bends the sheet 62 to form a qualified finished product 63. The finished product 63 is then further clamped with the help of the transfer robot arm 4 and transferred to a nearby material box for storage.

[0059] Example 2

[0060] See also Figures 1-6 、 Figure 8-Figure 9 In order to ensure that the combined stamping assembly 2 can be stably assembled on the workbench 1 and that the hydraulic telescopic cylinder 26 can drive the lifting platform 23 to stably rise and fall on the support platform 22 in a relatively sliding manner, the following technical solutions are provided.

[0061] The workbench 1 is fixedly connected to the machine platform 11, the assembly platform 21 is fixedly connected to the machine platform 11, a vertically arranged guide column A211 is fixedly connected between the top of the support platform 22 and the assembly platform 21, the lifting platform 23 is slidably connected to the guide column A211, the cylinder barrel of the hydraulic telescopic cylinder 26 is fixedly installed on the top of the support platform 22, and the movable end of the hydraulic telescopic cylinder 26 is fixedly connected to the lifting platform 23.

[0062] The setting of the machine platform 11 can ensure that the assembly table 21 is stably installed at a specific height position, and the guide column A211 arranged in the vertical direction cooperates with the lifting platform 23. When the hydraulic telescopic cylinder 26 telescopically moves, it can drive the lifting platform 23 to rise and fall stably in the vertical direction.

[0063] In order to ensure that the punching seat 24 and the cushion seat 25 can be stably assembled on the lifting platform 23 and the assembly platform 21 respectively, and realize the assembly combination of the punching seat 24, the cushion seat 25 and the corresponding reversing component 28, the following technical solution is provided.

[0064] The reversing assembly 28 includes a spline shaft A281, an upper drive gear 282, a lower drive gear 283, and an upper transmission gear 284 and a lower transmission gear 285 that are respectively engaged with the upper drive gear 282 and the lower drive gear 283. The upper drive gear 282 and the lower drive gear 283 are respectively rotatably installed in the lifting platform 23 and the assembly platform 21. The upper transmission gear 284 is fixed to the periphery of the stamping seat 24, and the lower transmission gear 285 is fixed to the periphery of the pad 25. The spline shaft A281 is rotatably installed between the top of the support platform 22 and the assembly platform 21. The axis of the lower drive gear 283 is fixed to the spline shaft A281, and the spline shaft A281 is slidably plugged into the axis of the upper drive gear 282.

[0065] Since the spline shaft A281 and the upper drive gear 282 maintain sliding connection at the axis center, when the lifting platform 23 and the stamping seat 24 and the upper drive gear 282 assembled therein are lifted and lowered, power can always be stably transmitted between the spline shaft A281 and the upper drive gear 282, thereby ensuring that the upper drive gear 282 and the lower drive gear 283 always maintain synchronous operation.

[0066] Furthermore, when the upper driving gear 282 and the lower driving gear 283 are in synchronous operation, they can always drive the upper transmission gear 284 and the lower transmission gear 285 to maintain synchronous operation, thereby achieving synchronous operation of the stamping seat 24 and the pad seat 25.

[0067] When the lifting platform 23 moves from the bottom end to the top end of the stroke, the transmission component 29 can drive the reversing component 28 to operate, just driving the punching seat 24 and the cushion seat 25 to operate 180 degrees.

[0068] Example 3

[0069] See also Figure 2-Figure 7 In order to ensure that the lifting platform 23 can transmit power to the reversing component 28 through the transmission component 29 during the upward process, thereby driving the reversing component 28 to operate stably and ensuring the stable installation of the transmission component 29, the following technical solutions are provided.

[0070] The transmission assembly 29 includes a transmission rack 291, a rotating gear 292, an inner ratchet 293, a transmission shaft 294, a pawl 295 and a matching combination of a worm wheel 296 and a worm 297. The transmission rack 291 is fixedly mounted on the top of the support platform 22 and arranged in the vertical direction. The rotating gear 292 is rotatably mounted on the lifting platform 23 and is matched with the transmission rack 291. The inner ratchet 293 is arranged on the inner side of the rotating gear 292. The transmission shaft 294 is rotatably mounted on the lifting platform 23 and arranged at the axis center of the inner ratchet 293. The outer periphery of the transmission shaft 294 is rotatably mounted with a pawl 295 that remains engaged with the inner ratchet 293. The worm 297 is coaxially fixed to the transmission shaft 294. The worm wheel 296 is fixed to the axis center of the upper drive gear 282 and maintains a sliding connection with the spline shaft A281.

[0071] To ensure that the pawl 295 can always expand outward and engage with the ratchet teeth of the inner ratchet 293, a spring 298 is installed between the transmission shaft 294 and the pawl 295. When the lifting platform 23 and its rotating gear 292 and other components are descending, the rotating gear 292 cooperates with the transmission rack 291 and drives the inner ratchet 293 to maintain synchronous reverse rotation. During this process, the operation of the inner ratchet 293 cannot transmit power through the pawl 295 to drive the transmission shaft 294 and the worm 297 to operate, and the power transmission is in a disconnected state.

[0072] When the lifting platform 23 is rising, the rotating gear 292 cooperates with the transmission rack 291 to drive the inner ratchet 293 to rotate synchronously in the forward direction. During this process, the operation of the inner ratchet 293 can drive the transmission shaft 294 and the worm 297 to operate through the pawl 295, and then the worm 297 drives the worm wheel 296 and the upper drive gear 282 to operate stably, so that the power can be stably transmitted to the reversing component 28 through the transmission component 29.

[0073] Since the combination of the worm wheel 296 and the worm 297 has the characteristics of deceleration and torque increase and one-way self-locking, the worm 297 can drive the worm wheel 296 to operate stably, and then drive the reversing component 28 and the feeding component 27 to operate stably. The power can only be transmitted to the worm wheel 296 in one direction through the worm 297. When the worm 297 is in a stationary state, it can ensure that the worm wheel 296 and the feeding component 27 and the reversing component 28 associated with the worm wheel 296 are in a locked state without invalid operation, thereby ensuring the stability of the processing of the copper nose finished product 63.

[0074] When the lifting platform 23 is at the bottom of its travel, the punch head 241 passes through the sheet 61 and is inserted into the punch hole 251, pushing the punched sheet 62 downward into the vibrating feeder 3. At this time, the punch head 241 is in a mating connection with the punch hole 251 and the sheet 61. To prevent the lifting platform 23 from directly triggering the transmission assembly 29, the reversing assembly 28, and the feeding assembly 27 to directly operate during the upward movement, thereby interfering with the transmitted sheet 61, the length of the transmission rack 291 is smaller than the travel design of the lifting platform 23. That is, when the lifting platform 23 is at the bottom of its travel, the rotating gear 292 is separated from the bottom end of the transmission rack 291, preventing the lifting platform 23 from being directly acted upon by the transmission rack 291 in the initial stage of its upward movement. Only when the lifting platform 23 rises and causes the punch head 241 to be completely separated from the punch hole 251 and the sheet 61, do the rotating gear 292 and the transmission rack 291 come into play.

[0075] Example 4

[0076] See also Figure 2-5 、 Figures 8-10 In order to ensure that the feeding assembly 27 can be stably assembled on the assembly table 21 and that the feeding assembly 27 can achieve power connection with the transmission assembly 29, the following technical solutions are provided.

[0077] The feeding assembly 27 includes a lower transmission roller 271, a transmission bevel gear A272, and a drive shaft 273 rotatably mounted on the assembly table 21. The lower transmission roller 271 is distributed on both sides of the pad 25. The material plate 61 is carried on the lower transmission roller 271. A transmission sprocket A2711 is fixed on the same side of the lower transmission roller 271. The groups of transmission sprockets A2711 arranged on the same side of the pad 25 are powered by chains.

[0078] The axis center of the lower driving gear 283 is fixed with a driving bevel gear A2831 that is meshed with the driving bevel gear A272. The axis center of the driving bevel gear A272 is fixed with a driving sprocket B2721. The driving shaft 273 includes two groups and is respectively arranged on both sides of the pad 25. The two ends of the driving shaft 273 are respectively fixed with a driving sprocket C2731 and a driving sprocket D2732. The driving sprocket C2731 and the driving sprocket B2721 are dynamically connected through a chain. The driving sprocket D2732 is dynamically connected to a group of driving sprockets A2711 on the same side through a chain.

[0079] The lower transmission roller 271 is provided with one or two sets of transmission sprockets A2711. The transmission sprockets A2711 on two adjacent sets of lower transmission rollers 271 are connected by a chain to ensure stable power transmission. There are also two sets of transmission sprockets B2721, which are connected to the corresponding transmission sprockets C2731 on both sides.

[0080] When the transmission component 29 runs and drives the lower driving gear 283 in the reversing component 28 to operate, it can drive the driving bevel gear A2831 to operate stably, and then drive the driving bevel gear A272 and the transmission sprocket B2721 to operate stably. The combination of the transmission sprocket B2721 and the transmission sprocket C2731 drives the driving shaft 273 and the transmission sprocket D2732 to operate stably, and the combination of the transmission sprocket D2732 and the transmission sprocket A2711 and the combination between the transmission sprockets A2711 drive each group of lower transmission rollers 271 to maintain synchronous and stable operation, thereby stably feeding the material plate 61 carried thereon.

[0084] The adjusting bracket 274 can be stably raised and lowered in the vertical direction under the guidance of the guide column B212. Under the action of the support spring A2121, the adjusting bracket 274 and the upper transmission roller 275 provided thereon can be pushed down stably and achieve a close fit with the material sheet 61. The cooperation between the upper transmission roller 275 and the lower transmission roller 271 can achieve stable transmission of the material sheet 61.

[0085] During the operation of the lower transmission roller 271, the combination of the driving bevel gear B2712 and the transmission bevel gear B2761 can drive the spline shaft B276 to operate stably, and then the spline shaft B276 drives the driving bevel gear C2741 assembled on the adjustment bracket 274 to operate stably, and then through the combination of the transmission bevel gear C2752 and the transmission sprocket E2751, each group of upper transmission rollers 275 can always maintain synchronous operation.

[0086] It should also be noted that the combination of the driving bevel gear B2712 and the transmission bevel gear B2761 is arranged symmetrically with the combination of the driving bevel gear B2712 and the transmission bevel gear B2761, so that the upper transmission roller 275 and the lower transmission roller 271 maintain reverse and constant speed operation, thereby achieving stable transmission of the material plate 61.

[0087] In order to further accurately position the transported material sheet 61 to ensure stable transport and feeding of the material sheet 61 , the following technical solution is provided.

[0088] The feeding assembly 27 also includes a sliding seat 277 and a longitudinal guide roller 278. A horizontally arranged guide column C2742 is fixedly connected to the adjusting bracket 274.

[0091] See also Figure 11-13 In order to ensure that the forming assembly 5 can be stably assembled on the workbench 1 and that the forming assembly 5 can perform punching and bending operations on the stamped sheet 62, the following technical solution is provided.

[0092] The forming assembly 5 includes a mounting seat 51, a pad 52, a lifting bracket 53, a pressure seat 54, a punching head 55, a telescopic cylinder A56, and a telescopic cylinder B57.

The telescopic cylinder B57 is fixedly installed on the lifting bracket 53, and the movable end of the telescopic cylinder B57 is fixedly connected to the punching head 55.

[0093] The pad 52 has a guide column D521 and a support spring C522 and is located at the top of the pressure groove 511. When the material 62 to be processed is placed on it, the material 62 can remain in contact with the pressure groove 511 and the pad 52. When the telescopic cylinder A56 drives the lifting bracket 53 and the pressure seat 54 to move downward, the pad 52 is in the sinking groove 512, and the cooperation between the pressure seat 54 and the pressure groove 511 can bend the wings on both sides of the material 62 upward. Then the telescopic cylinder B57 drives the punching head 55 to move downward, punching out a wiring hole on the head of the material 62. The punched waste can be discharged downward from the leakage hole opened on the pad 52 and the mounting seat 51 under the push of the punching head 55.

[0094] In order to ensure that the wings on both sides of the sheet 62 are precisely bent to produce a high-quality finished product 63, the following technical solution is provided.

[0095] The forming assembly 5 also includes a telescopic cylinder C58 and a bending seat 59. The mounting seat 51 is provided with guide grooves 513 arranged on both sides of the pressing groove 511. The bending seat 59 is slidably installed in the guide grooves 513. The telescopic cylinder C58 is fixedly installed on the mounting seat 51, and the movable end of the telescopic cylinder C58 is fixedly connected to the bending seat 59.

[0096] After the pressing seat 54 moves downward and presses the sheet 62 into shape, the wings on both sides are bent upward and tilted. Then, the telescopic cylinders C58 on both sides are controlled to drive the bending seat 59 to move along the guide groove 513, and the bending seat 59 further bends the wings to achieve precise bending of the wings.
