Technical Field
[0001] This invention relates to the field of mechanical equipment technology, and in particular to a multi-station continuous stamping forming equipment for tubular thin-walled metal pen barrels. Background Technology
[0002] In related technologies, stylus pen barrels are mostly made of plastic, with a small portion made of metal. For metal pen barrels, multiple barrels are typically formed at once using die-casting molds. The die-cast metal pen barrels are semi-finished products, and subsequent stamping jigs or dies are used to stamp and shape different parts of the metal pen barrel, punch holes, or chamfer them. However, the inventors found in actual production that the stamping of tubular thin-walled metal pen barrels currently requires manual loading of the tubular thin-walled metal pen barrels into different stamping dies for stamping. This process has low automation and low integration of assembly and processing, resulting in low production efficiency. Furthermore, the manual operation often results in uncontrollable issues with the accuracy of the loading position, leading to low stamping precision of the tubular thin-walled metal pen barrels and severely limiting the production yield of tubular thin-walled metal pen barrels.
[0003] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] Please refer to the following: Figures 1 to 12 The multi-station continuous stamping forming equipment 100 for tubular thin-walled metal pen barrels provided in this application embodiment will now be described. The multi-station continuous stamping forming equipment 100 for tubular thin-walled metal pen barrels includes a worktable 10, a feeding device 20, a discharging device 30, and a moving device 40.
[0025] The feeding device 20 is located on the left side of the workbench 10, the unloading device 30 is located on the right side of the workbench 10, and the moving device 40 is located on the rear side of the workbench 10. The workbench 10 has at least two stamping stations arranged along the X-axis, and the stamping stations are detachably equipped with lower stamping dies 11. The feeding device 20 is provided with a first storage device 21 for carrying the material tray 300, a feeding positioning device 22 for positioning the metal pen barrel 200, and a feeding transfer device 23 for transferring the metal pen barrel 200 from the material tray 300 to the feeding positioning device 22. The unloading device 30 is provided with an unloading arm for transferring the metal pen barrel 200. The device includes a receiving device 31, a second storage device 32 for carrying the material tray 300, and a material transfer device 33 for transferring the metal pen barrel 200 of the unloading connecting device 31 to the material tray 300; the moving device 40 has a transfer movable seat 41, which can move along the X, Y and Z axes. The transfer movable seat 41 is provided with a clamping assembly 42 and an upper stamping die 43. When the transfer movable seat 41 moves back and forth, it can sequentially transfer the metal pen barrel 200 of the loading positioning device 22 to the stamping station and the unloading transfer device 33, and make the upper stamping die 43 and the lower stamping die 11 stamp the metal pen barrel 200.
[0026] Specifically, compared with the prior art, firstly, by setting a feeding device 20 on the left side of the workbench 10, a discharging device 30 on the right side, and a moving device 40 on the rear side, and by linking the moving device 40 with the transfer seat 41, the metal pen barrel in the feeding device 20 can be transferred from left to right to the stamping station and the discharging station in sequence. The feeding, stamping, and discharging operations of the metal pen barrel are completed in an automated manner without the need for operator intervention, thereby improving the stamping efficiency of the metal pen barrel. Secondly, by setting a feeding positioning device 22, the position of the metal pen barrel can be positioned before it is transferred to the stamping station, thereby ensuring that the metal pen barrel is in the preset stamping position during subsequent stamping operations, ensuring the stamping accuracy of the metal pen barrel, and further improving the production yield of the metal pen barrel.
[0027] More specifically, the first storage device 21 includes two first tracks 211, a first storage frame 213, a first stop mechanism 214, and a first distributing mechanism 215; the two first tracks 211 extend along the Y-axis and are spaced along the X-axis, and conveyor belts 212 are provided on opposite sides of the two first tracks 211; the first storage frame 213 is located on the top front side of the first track 211, and the first storage frame 213 can stack material trays 300 from bottom to top; the first stop mechanism 214 is provided one-to-one with the two first tracks 211; the first stop mechanism 214 has a first The first stop plate 2141 can extend into the first storage frame 213 to stop the material tray 300; the first material distribution mechanism 215 is located between the two first tracks 211 and at the bottom of the first storage frame 213; when the first material distribution mechanism 215 abuts against the first material tray 300 at the bottom of the first storage frame 213, the first stop mechanism 214 can stop the second material tray 300 at the bottom of the first storage frame 213, and the first material tray 300 at the bottom of the first storage frame 213 is transferred to the conveyor belt 212 by the first material distribution mechanism 215.
[0028] It should be noted that the first storage frame 213, the first stop mechanism 214, and the first dispensing mechanism 215 constitute a tray transport module, and the first storage device 21 has two tray transport modules; one tray transport module is located in front of the two first guide rails 441 and is used to lower the tray; the other tray transport module is located behind the two first guide rails 441 and is used to stack the trays. Therefore, after the tray is lowered from the front tray transport module, the loading and transfer device 23 can pick up the metal pen barrels in the tray and load them into the loading and positioning device 22; after all the metal pen barrels in the tray have been loaded, they are stacked together by the rear tray transport module.
[0029] Preferably, the first stop mechanism 214 includes a vertical actuator 2142 and a horizontal actuator 2143. The vertical actuator 2142 is fixedly installed on the first guide rail 441, and the horizontal actuator 2143 is installed on the telescopic rod of the vertical actuator 2142. The first stop plate 2141 is installed on the telescopic rod of the horizontal actuator 2143. By extending and retracting the horizontal actuator 2143 and the vertical actuator 2142, the first stop plate 2141 moves in linkage to stop the second bottom material tray among multiple material trays, and allows the first bottom material tray to be transferred to the first material distribution mechanism 215. The first material distribution mechanism 215 includes a material distribution execution cylinder 2151 and a material distribution plate 2152 provided on the telescopic rod of the material distribution execution cylinder 2151. When the material distribution execution cylinder 2151 drives the material distribution plate 2152 to move upward and stop the bottom first material tray among the multiple material trays, the first stop mechanism 214 stops the bottom second material tray among the multiple material trays; then the material distribution execution cylinder 2151 drives the material distribution plate 2152 to move downward, so that the bottom first material tray is transferred to the conveyor belt 212.
[0030] In some embodiments, the feeding and positioning device 22 includes a rotary positioning module 221, a length detection module 222, and a waste unloading module 223. The rotary positioning module 221, the length detection module 222, and the waste unloading module 223 are arranged at intervals along the X-axis and located between the first track 211 and the worktable 10.
[0031] The rotation positioning module 221 includes a first fixed plate 2211, a first supporting fixture 2212 disposed on the first fixed plate 2211 and used to support the metal pen barrel 200, a first rotary actuator 2213 disposed on the front side of the first supporting fixture 2212 and used to rotate the metal pen barrel 200, and a first sensing component 2214 disposed on the first fixed plate 2211 and located on both sides of the first supporting fixture 2212. The first sensing component 2214 is a photoelectric sensor, including a receiving end and a transmitting end. It uses a plane on the outer surface of the metal pen barrel as a positioning surface in the circumferential direction of the metal pen barrel. When the metal pen barrel is rotated and adjusted to meet the preset requirements in the circumferential direction, the light from the transmitting end can be obtained by the receiving end. At this time, the rotation of the first rotary actuator 2213 is stopped to adjust the metal pen barrel to the preset position.
[0032] It should be noted that the first rotary actuator 2213 is a rotary actuator cylinder. The output end of the rotary actuator cylinder is equipped with a gripper cylinder. The gripper cylinder clamps out the metal pen barrel, and the rotary actuator cylinder drives the pen barrel to rotate to adjust the position of the metal pen barrel.
[0033] As described above, the length detection module 222 includes a second fixed plate 2221, a second supporting fixture 2222 disposed on the second fixed plate 2221 and used to support the metal pen barrel 200, a slide cylinder 2223 disposed on the front side of the second supporting fixture 2222, and a length detection component 2224 disposed on the slide cylinder 2223. When the metal pen barrel is transferred from the rotary positioning module 221 to the length detection module 222, the metal pen barrel can be supported on the second supporting fixture 2222, and the length detection component 2224 is driven by the slide cylinder 2223 to identify the length of the metal pen barrel. Once the length of the metal pen barrel meets the design length, it can be loaded to the stamping station for stamping operation. Once the length of the metal pen barrel does not meet the design length, it is transferred to the scrap unloading module 223 for unloading.
[0034] Specifically, the waste unloading module 223 includes a third fixed plate 2231, a third movable plate 2232 that is movably mounted on the third fixed plate 2231 along the Y-axis, a waste frame 2234 that is fixedly mounted on the third movable plate 2232, and a waste actuation cylinder 2233 for driving the third fixed plate 2231 to move along the Y-axis. When the metal pen barrel is waste, the waste actuation cylinder drives the third movable plate 2232 to move forward, so that the waste frame 2234 is located on one side of the second bearing fixture 2222, so that the metal pen barrels of the defective products can be transferred to the waste frame 2234 in the subsequent picking up.
[0035] Preferably, the second fixing plate 2221 is fixedly installed on the transverse actuator 2225. After the feeding and transferring device 23 transfers the metal pen barrel from the rotary positioning module 221 to the length detection device, if the metal pen barrel is detected as a good product, the transverse actuator 2225 drives the length detection module 222 to move to the right and closer to the worktable 10, so that the subsequent moving device 40 can transfer the metal pen barrel in the length detection device to the stamping station. This structure can improve the automation level of the stamping equipment, thereby reducing the possibility of human intervention and improving the reliability of metal pen barrel feeding and stamping.
[0036] More specifically, the loading and transferring device 23 includes a loading and transferring seat 231, an X-axis actuator 232 for driving the loading and transferring seat 231 to move along the X-axis, a Y-axis actuator 233 for driving the loading and transferring seat 231 to move along the Y-axis, and a Z-axis actuator 234 for driving the loading and transferring seat 231 to move along the Z-axis; the Y-axis actuator 233 is located at the X-axis actuator 232, the Z-axis actuator 234 is located at the Y-axis actuator 233, and the loading and transferring seat 231 is located at the Z-axis actuator 234; the loading and transferring seat 231 is provided with a first rotary actuator 235, and the output end of the first rotary actuator 235 is provided with a first gripper cylinder 236; the loading and transferring seat 231 is also provided with a second gripper cylinder 237 and a third gripper cylinder 238, and the first gripper cylinder 236, the second gripper cylinder 237, and the third gripper cylinder 238 are arranged at intervals along the X-axis. This structure allows the loading and transfer seat 231 to move in conjunction with the X-axis actuator 232, Y-axis actuator 233 and Z-axis actuator 234, so that the metal pen barrel can be picked up from the material tray and sequentially loaded onto the first support fixture 2212 and the second support fixture 2222. This simplifies the overall mechanical mechanism of the stamping equipment, reduces the number of operating movements of the loading and transfer device 23, and further improves the efficiency of the loading operation.
[0037] It should be noted that the structures of the X-axis actuator, Y-axis actuator, and Z-axis actuator are roughly the same, the difference being their transmission direction. They typically include a mounting base, a guide rail mounted on the mounting base, a slider movably mounted on the guide rail, a movable plate fixedly mounted on the slider, and an actuator motor or actuator cylinder that drives the movable plate to move. This is a conventional design method for those skilled in the art, and will not be described in detail here.
[0038] Understandably, the cooperation of the first rotary actuator 235 and the first gripper cylinder 236 can pick up the metal pen barrel from the tray, adjust its longitudinal setting from the horizontal direction, and load it onto the first support fixture 2212. The second gripper cylinder 237 can load the metal pen barrel from the first support fixture 2212 onto the second support fixture 2222. If the metal pen barrel in the second support fixture 2222 is defective, it will be picked up by the third gripper cylinder 238 and transferred to the waste box 2234 for removal from the production line.
[0039] In other embodiments, the stamping station includes at least a first forming station 101, a second forming station 102, a third forming station 103, a first punching station 104, a first chamfering station 105, and a second chamfering station 106 disposed on the worktable 10; the clamping assembly 42 includes a first clamping assembly 4201, a second clamping assembly 4202, a third clamping assembly 4203, a fourth clamping assembly 4204, a fifth clamping assembly 4205, a sixth clamping assembly 4206, and a seventh clamping assembly 4207 disposed on the transfer movable seat 41; when the transfer movable seat 41 moves back and forth, it can link the first clamping assembly 4201 to move back and forth between the length detection module 222 and the first forming station 106. The first forming station 101, the second clamping assembly 4202 reciprocates between the first forming station 101 and the second forming station 102, the third clamping assembly 4203 reciprocates between the second forming station 102 and the third forming station 103, the fourth clamping assembly 4204 reciprocates between the third forming station 103 and the first punching station 104, the fifth clamping assembly 4205 reciprocates between the first punching station 104 and the first chamfering station 105, the sixth clamping assembly 4206 reciprocates between the first chamfering station 105 and the second chamfering station 106, and the seventh clamping assembly 4207 reciprocates between the second chamfering station 106 and the unloading connecting device 31.
[0040] In other words, by moving the movable seat 41 back and forth, the metal pen barrel can be sequentially loaded to the first forming station 101 to complete the first forming and stamping, loaded to the second forming station 102 to complete the second forming and stamping, loaded to the third forming station 103 to complete the third forming and stamping, loaded to the first punching station 104 to complete the punching and stamping, loaded to the first chamfering station 105 to complete the first chamfering and stamping, and loaded to the second chamfering station 106 to complete the second chamfering and stamping.
[0041] Specifically, the moving device 40 also includes a first actuator 44 for driving the transfer seat 41 to move along the Y-axis and a second actuator 45 for driving the transfer seat 41 to move along the X-axis and Z-axis; the first actuator 44 is located on the rear side of the worktable 10, and the second actuator 45 and the transfer seat 41 are located on the first actuator 44.
[0042] More specifically, the first actuator 44 includes a first guide rail 441 extending along the Y-axis, a first slider 442 movably disposed on the first guide rail 441, a first transfer seat 443 fixedly disposed on the first slider 442, and a first actuator motor 444 for driving the first transfer seat 443 to move; the second actuator 45 includes a second guide rail 451 extending along the X-axis and disposed on the first transfer seat 443, a second slider 452 movably mounted on the second guide rail 451, a third guide rail 453 fixedly mounted on the second slider 452 and extending along the Z-axis, and a third guide rail 453 movably mounted on the third guide rail 453. A third slider 454 and a second actuator motor 455 fixedly mounted on a first transfer seat 443; the first transfer seat 443 is provided with a first limiting plate 4431, which has a first limiting groove 4432 penetrating its front and rear surfaces; a transfer movable seat 41 is fixedly mounted on the third slider 454, and the transfer movable seat 41 is provided with a first drive shaft 411; the rotating shaft of the second actuator motor 455 is provided with a first swing plate 4551, and the other end of the first swing plate 4551 is provided with a hole for the first drive shaft 411, which is inserted into the first drive hole 4552 and the first limiting groove 4432. When the rotating shaft of the first actuator motor 444 rotates, it can drive the first swing plate 4551 to swing, thereby linking the first drive shaft 411 to slide in the first limiting groove 4432, thereby realizing the linkage of the loading transfer seat 231 to move back and forth along the X-axis and Z-axis, so as to gradually transfer the metal pen 200 to the stamping station and the unloading connection device 31.
[0043] In other embodiments, the clamping assembly 42 includes a fourth substrate 421, a fourth gripper cylinder 422 disposed on the fourth substrate 421, a fourth clamping plate 423 disposed at the output end of the fourth gripper cylinder 422, and a fourth clamping fixture 424 disposed on the fourth clamping plate 423. The fourth clamping fixture 424 is provided with a clamping notch 4241 that fits the outer surface of the metal pen barrel 200. Each time the movable transfer seat 41 moves back and forth, the clamping assembly 42 clamps the metal pen barrel and completes the transfer of the metal pen barrel from one station to the right to another station.
[0044] Specifically, the fourth clamping plate 423 is equipped with a stamping actuation cylinder 425, and the telescopic rod of the stamping actuation cylinder 425 is equipped with a stamping movable plate 426. The upper stamping die 43 is located on the stamping movable plate 426. The upper stamping die 43 is located on the lower surface of the stamping movable plate 426, so that the upper stamping die 43 and the fourth clamping fixture 424 are spaced apart. When the upper stamping die 43 and the lower stamping die 11 are stamping the metal pen barrel, the clamping assembly 42 can choose to continuously clamp the metal pen barrel or pause clamping the metal pen barrel, so that the upper stamping die 43 and the lower stamping die 11 can close the mold and stamp the metal pen barrel. The fourth substrate 421 is also equipped with a fourth pressing cylinder 427. The telescopic rod of the fourth pressing cylinder 427 is provided with a pressing fixture 428. When the metal pen is transferred to the lower stamping die 11, before the clamping fixture releases its grip on the metal pen, the metal pen can be pressed onto the lower stamping die 11 in advance by the pressing fixture 428, thereby ensuring that the position of the metal pen is not changed and improving the stamping accuracy and stamping yield of the metal pen.
[0045] More specifically, the lower stamping die 11 includes a die base plate 111, a die bottom plate 112, a die top plate 113, a stamping cylinder, and a first mandrel 114. The mold base plate 111 is detachably installed at the stamping station, and the mold bottom plate 112 is located on the top of the mold base plate 111. The mold bottom plate 112 has several through holes 1121 penetrating its upper and lower surfaces. Each through hole 1121 is equipped with a drive slide that can move up and down. A punch is provided on the top of the drive slide. The mold top plate 113 is located on the top of the mold bottom plate 112. The mold top plate 113 is equipped with a lower die 1131. A stamping cylinder is configured according to the number of drive slides. The stamping cylinder can drive the drive slides to move up and down, so that the punch extends from the bottom of the lower die 1131 to perform stamping operations on the metal pen barrel 200. The first mandrel 114 is installed at the stamping station and located in front of the mold top plate 113 through a mandrel actuator. When the metal pen barrel 200 is supported by the lower die 1131, the mandrel actuator can drive the first mandrel 114 to move backward to insert into the metal pen barrel 200.
[0046] Furthermore, the first mandrel 114 is inserted into the metal pen barrel to support it, ensuring that the metal pen barrel does not deform except at the areas requiring processing during stamping, punching, or embossing. The mandrel actuator includes a fourth mounting plate 1141, a fourth guide rail 1142 disposed on the fourth mounting plate 1141 and extending along the Y-axis, a fourth slider 1143 movably mounted on the fourth guide rail 1142, and a fourth movable seat 1144 fixedly mounted on the fourth slider 1143. The fourth movable seat 1144 is provided with a first insertion interface 1145, and the front end of the first mandrel 114 is provided with a first insertion post 1146 for inserting into the first insertion interface 1145. The fourth movable seat 1144 is driven by a fourth actuator motor 1147 to move along the extension direction of the fourth guide rail 1142.
[0047] In some embodiments, the drive position includes a first position 1151, a second position 1152, and a third position 1153; the punch includes a first punch 1161 disposed on the top of the first position 1151, a second punch 1162 disposed on the top of the second position 1152, and a third punch 1163 disposed on the top of the third position 1153; and the stamping cylinder includes a first stamping cylinder 1171 for driving the first position 1151 to move up and down, a second stamping cylinder 1172 for driving the second position 1152 to move up and down, and a third stamping cylinder 1173 for driving the third position 1153 to move up and down.
[0048] When the first forming station 101, the second forming station 102, and the third forming station 103 do not require the use of punches for stamping, punching, or embossing, the metal pen barrel can be stamped and shaped using only the upper die 431 and the lower die 1131. When the first punching station 104 requires punching the metal pen barrel, the first stamping cylinder 1171 can be controlled independently, and the first punch 1161 can be linked by the first sliding position 1151 to punch the metal pen barrel. Operation: When the first chamfering station 105 needs to perform embossing on the metal pen barrel, the second stamping cylinder 1172 can be controlled independently to work, and the second punch 1162 can be linked by the second moving position 1152 to perform embossing stamping on the metal pen barrel; when the second chamfering station 106 needs to perform chamfering on the metal pen barrel, the third stamping cylinder 1173 can be controlled independently to work, and the third punch 1163 can be linked by the third moving position 1153 to perform chamfering stamping on the metal pen barrel.
[0049] It is understandable that the first punch 1161, the second punch 1162 and the third punch 1163 mentioned above can be adapted to meet actual stamping needs.
[0050] In other embodiments, the second storage device 32 has the same structure as the first storage device 21, and the unloading transfer device 33 has the same structure as the loading transfer device 23. The unloading connecting device 31 includes a connecting base 311, a fifth guide rail 312 provided on the connecting base 311 and extending along the X-axis, a fifth slider 313 movably provided on the fifth guide rail 312, a connecting moving seat 314 provided on the fifth slider 313, a connecting support clamp 315 provided on the connecting moving seat 314, and a connecting gripper cylinder 316 for clamping the metal pen barrel 200. The connecting moving seat 314 is driven by a connecting execution motor 317 to move along the extension direction of the fifth guide rail 312.
