Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a multi-station stamping die for forming 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 barrels, multiple barrels are typically die-cast in one go. These die-cast barrels are semi-finished products, requiring subsequent stamping and punching operations at high-precision locations based on the installation positions of electromagnetic components and other parts. However, the inventors discovered in actual production that there is currently a lack of corresponding stamping dies to automate the stamping and punching of stylus pen barrels. Operators must manually load the metal barrels into a fixture, complete the stamping or punching at one location, and then input them into the next fixture for further stamping or punching. This method is not only inefficient but also makes it difficult to guarantee the stamping and punching precision of the metal barrels, severely limiting the installation accuracy of subsequent electromagnetic components and other parts, thus hindering further improvements in stylus pen production yield.

[0003] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a multi-station stamping die for forming metal pen barrels. This effectively solves the technical defects in the existing technology, where the metal pen barrels of touch pens lack automated stamping, shaping, and punching due to the lack of stamping dies, resulting in low operating efficiency and low shaping and punching accuracy in the manufacturing of metal pen barrels.

[0005] This utility model provides a multi-station stamping die for forming metal pen barrels, including... The worktable has at least three stations: a loading station, a stamping station, and a unloading station, arranged sequentially at intervals along the X-axis; and... The feeding robot has a transport moving seat, a feeding actuator for driving the transport moving seat to move along the X-axis, Y-axis and Z-axis, and a gripping mechanism located on the transport moving seat for gripping metal pen barrels. Each stamping station is equipped with a lower stamping die, and the transport and moving seat is equipped with an upper stamping die corresponding to the lower stamping die. The lower stamping die has a lower concave die, and the upper stamping die has an upper concave die. The front side of the lower stamping die is equipped with a first mandrel and a mandrel actuator that drives the first mandrel to move along the Y-axis to enter or exit the lower concave die.

[0006] The beneficial effect of the multi-station stamping die for forming metal pen barrels provided by this utility model is that, compared with the prior art, during operation, the metal pen barrel is picked up from the loading station by the material grabbing mechanism, and the conveying moving seat is driven by the feeding execution mechanism to move the metal pen barrel to the stamping station and the unloading station in sequence. The upper die, the lower die and the first mandrel are used to complete the stamping and punching operation of the metal pen barrel. This structure, firstly, by setting up a lower stamping die, an upper stamping die, and a first mandrel at the stamping station, allows the metal pen barrel to be fed into the lower die. After the first mandrel is inserted into the metal pen barrel to stabilize its position, the upper and lower stamping dies are then closed to perform stamping or punching operations. This ensures that the metal pen barrel is in a stable processing state during the stamping and punching operations, thereby ensuring that the stamping and punching accuracy meets the design requirements. This guarantees that the subsequent metal pen barrel can be accurately fitted with electromagnetic components and other parts, further improving the production yield of the touch pen. Secondly, by linking the feeding actuator with the moving seat to move along the X, Y and Z axes, the metal pen barrel is sequentially transferred from the loading station to the stamping station and the unloading station.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 8 The multi-station stamping die 100 for forming metal pen barrels provided in this application embodiment will now be described. The multi-station stamping die 100 for forming metal pen barrels includes a worktable 10 and a feeding robot 20.

[0025] The workbench 10 has at least a loading station 101, a stamping station, and a unloading station arranged sequentially along the X-axis. The feeding robot 20 has a transport moving seat 21, a feeding execution mechanism 22 for driving the transport moving seat 21 to move along the X-axis, Y-axis, and Z-axis, and a gripping mechanism 23 located on the transport moving seat 21 for gripping metal pen barrels. Each stamping station is equipped with a lower stamping die 30, and the transport moving seat 21 is equipped with an upper stamping die 40 corresponding to the lower stamping die 30. The lower stamping die 30 has a lower die 31, and the upper stamping die 40 has an upper die 41. The front side of the lower stamping die 30 is equipped with a first mandrel 50 and a mandrel execution mechanism for driving the first mandrel 50 to move along the Y-axis into or out of the lower die 31.

[0026] Specifically, during operation, the material gripping mechanism 23 grips the metal pen barrel from the loading station 101, and the material feeding actuator 22 drives the transport moving seat 21 to sequentially transfer the metal pen barrel to the stamping station and the unloading station 108. The upper die 41, lower die 31, and first mandrel 50 work together to complete the stamping and punching operations of the metal pen barrel. Compared with the prior art, firstly, by using the lower stamping die 30, upper stamping die 40, and first mandrel 50 set at the stamping station, after the metal pen barrel is loaded onto the lower die 31, the first mandrel 50 is first inserted into the metal pen barrel to stabilize its position before the upper stamping die 40 and lower stamping die 30 are closed for stamping and shaping. The first aspect is that the stamping and punching operation ensures that the metal pen barrel is in a stable processing state during the stamping and punching process, thereby ensuring that the stamping and punching accuracy meets the design requirements and that the subsequent metal pen barrel can accurately install electromagnetic components and other parts, thus further improving the production yield of the stylus pen. Secondly, the feeding actuator 22 is linked to the moving transport seat 21 to move along the X, Y and Z axes, thereby transferring the metal pen barrel from the loading station 101 to the stamping station and unloading station 108 in sequence. No operator is required to load or unload the material, thus realizing fully automated metal pen barrel stamping and punching operation, which greatly improves the efficiency of metal pen barrel stamping and punching operation.

[0027] It should be noted that both the loading station 101 and the unloading station 108 are equipped with trays (not shown in the figure). The tray at the loading station 101 stores the metal pen barrels to be processed, and the tray at the unloading station 108 is used to recycle and store the metal pen barrels that have completed the stamping operation.

[0028] In some embodiments, the stamping station includes a first forming station 102, a second forming station 103, a third forming station 104, a first punching station 105, a first chamfering station 106, and a second chamfering station 107. The loading station 101, the first shaping station 102, the second shaping station 103, the third shaping station 104, the first punching station 105, the first chamfering station 106, the second chamfering station 107, and the unloading station 108 are arranged sequentially at intervals along the X-axis. The number of gripping mechanisms 23 is the same as the number of stations. The feeding execution mechanism 22 moves back and forth between two adjacent stations in conjunction with one gripping mechanism 23, so that the metal pen barrel is sequentially moved from the loading station 101 along the X-axis to the first shaping station 102, the second shaping station 103, the third shaping station 104, the first punching station 105, the first chamfering station 106, the second chamfering station 107, and the unloading station 108.

[0029] Specifically, the feeding actuator 22 includes a first base plate 221, a first guide rail 222 fixedly mounted on the first base plate 221, a first slider 223 movably mounted on the first guide rail 222, a first movable seat 224 fixedly mounted on the first slider 223, and a first actuator motor 225 for driving the first movable seat 224 to move back and forth along the Y-axis. The transport movable seat 21 is movably mounted on the front surface of the first movable seat 224 through a sliding mechanism, and is driven by the second actuator motor 215 to move left and right along the X-axis and up and down along the Z-axis.

[0030] More specifically, the sliding mechanism includes a second guide rail 211 fixedly mounted on the first movable seat 224 and extending along the X-axis, a second slider 212 movably mounted on the second guide rail 211, a third guide rail 213 fixedly mounted on the second slider 212 and extending along the Z-axis, and a third slider 214 fixedly mounted on the third guide rail 213; the transport movable seat 21 is fixedly mounted on the third slider 214. A second actuator motor 215 is mounted on the first movable seat 224, and the front surface of the first movable seat 224 is provided with a stroke limiting plate 2241, which has a stroke limiting groove 2242; the shaft of the second actuator motor 215 is mounted with a first swing plate 2151, and the other end of the first swing plate 2151 is provided with a first drive groove 2152; the transport movable seat 21 is connected to a first drive shaft 216, which slides into the first drive groove 2152 and the stroke limiting groove 2242.

[0031] During the process of sequentially transferring the metal pen barrel from the loading station 101 to the first forming station 102, the second forming station 103, the third forming station 104, the first punching station 105, the first chamfering station 106, the second chamfering station 107, and the unloading station 108 along the X-axis, the rotation of the shaft of the second actuator motor 215 drives the first swing plate 2151 to swing, which in turn drives the first drive shaft 216 to slide upward, to the right, and downward in the travel limiting groove 2242, completing the movement of the transport moving seat 21 to complete one metal pen barrel transfer operation. It should be noted that the first drive shaft 216 sliding upward, to the right, and downward in the travel limiting groove 2242 is the loading state, and the first drive shaft 216 sliding upward, to the left, and downward in the travel limiting groove 2242 is the reset state; this transmission structure simplifies the overall structure of the feeding robot 20 and enhances its stability in transporting the metal pen barrel.

[0032] In other embodiments, the material gripping mechanism 23 includes a material gripping fixing plate 231 fixedly installed on the transport moving seat 21, a gripper cylinder 232 fixedly installed on the material gripping fixing plate 231, a clamping plate 233 fixedly installed on the output end of the gripper cylinder 232, and a material clamping fixture 234 fixedly installed on the clamping plate 233. The material clamping fixture 234 has a material clamping groove 2341 adapted to the shape of a metal pen barrel. The material gripping fixing plate 231 is also equipped with a pressing execution cylinder 24, and the telescopic rod of the pressing execution cylinder 24 is equipped with a pressing plate 241. When the gripper cylinder 232 drives the two clamping plates 233 to move closer to each other, the clamping fixture 234 clamps the metal pen barrel and moves it to the lower die. Then, the pressing cylinder 24 drives the pressing plate 241 to move down, pressing the metal pen barrel onto the lower die 31. Then, the gripper cylinder 232 drives the two clamping plates 233 to move relative to each other, so that the clamping fixture 234 is disengaged from the metal pen barrel. This structure can accurately load the metal pen barrel into the lower die 31, thereby improving the accuracy of subsequent stamping, shaping and punching.

[0033] Specifically, the material gripping and fixing plate 231 is provided with a stamping guide hole 235 penetrating its upper and lower surfaces. A stamping guide post 236 that can move up and down is installed in the stamping guide hole 235. The upper stamping die 40 is fixedly installed on the stamping guide post 236. It also includes a stamping execution cylinder 25. The telescopic rod of the stamping execution cylinder 25 is provided with a stamping movable plate 251. The stamping movable plate 251 is fixedly connected to the top of the stamping guide post 236. When the pressing execution cylinder 24 drives the pressing plate 241 to move down and presses the metal pen barrel against the lower die 31, the stamping execution cylinder 25 can drive the upper stamping die 40 to move down, so that the upper die 41 and the lower die 31 cooperate to shape the metal pen barrel.

[0034] In some embodiments, the lower stamping die 30 includes a first base plate 32 fixedly installed on the worktable 10, a lower die base plate 33 fixedly installed on the upper surface of the first base plate 32, and a lower die top plate 34 fixedly installed on the upper surface of the lower die base plate 33. The lower die 31 is fixedly installed on the upper surface of the lower die top plate 34. The lower die base plate 33 is provided with a clearance opening 331 that penetrates its upper and lower surfaces. A drive insert 35 is movably installed in the clearance opening 331. The top of the drive insert 35 is provided with a punch. The punch can pass through the lower die top plate 34 and the lower die 31 and protrude from the bottom of the cavity of the lower die 31.

[0035] Understandably, the bottom of the punch directly abuts against the upper surface of the drive insert 35; therefore, the lower stamping die 30 of each station can change the shape, size or type of the punch according to actual needs for shaping, punching, chamfering or embossing operations, thereby improving the versatility of the lower stamping die 30 and facilitating the adaptive modification of stamping operations at different stations according to different stamping steps of the metal pen barrel.

[0036] Specifically, the drive insert 35 includes a first insert 351, a second insert 352, and a third insert 353 arranged sequentially along the Y-axis. The punch includes a first punch 361 on the upper surface of the first insert 351, a second punch 362 on the upper surface of the second insert 352, and a third punch 363 on the upper surface of the third insert 353. The first punch 361 is driven to move up and down by a first cylinder 3611 to punch holes in the metal pen barrel. The second punch 362 is driven to move up and down by a second cylinder 3621 to punch embossing on the metal pen barrel. The third punch 363 is driven to move up and down by a third cylinder 3631 to chamfer the metal pen barrel.

[0037] Preferably, the telescopic rod of the first cylinder 3611 is provided with a first drive plate 3612, and the first drive plate 3612 and the first insert 351 have abutting inclined surfaces on opposite sides. When the telescopic rod of the first cylinder 3611 extends, the first drive plate 3612 can abut against the first insert 351 and cause the first insert 351 to move upward; the telescopic rod of the second cylinder 3621 is provided with a second drive plate 3622, and the second drive plate 3622 and the second insert 352 have abutting inclined surfaces on opposite sides. The second drive plate 3622 can abut against the second insert 352 and cause the second insert 352 to move upward when the telescopic rod of the second cylinder 3621 is extended. The telescopic rod of the third cylinder 3631 is provided with a third drive plate 3632. The third drive plate 3632 and the third insert 353 are provided with abutting inclined surfaces on opposite sides. When the telescopic rod of the third cylinder 3631 is extended, the third drive plate 3632 can abut against the third insert 353 and cause the third insert 353 to move upward.

[0038] In other embodiments, the mandrel actuator includes a first fixed plate 51 fixedly mounted on the worktable 10 and located in front of the stamping station. A fourth guide rail 52 is mounted on the upper surface of the first fixed plate 51, and the fourth guide rail 52 extends along the Y-axis. A fourth slider 53 is movably mounted on the fourth guide rail 52, and a fourth movable plate 54 is fixedly mounted on the fourth slider 53. The fourth movable plate 54 has a fourth mounting seat 541, and a first insertion hole 542 is provided on the rear surface of the fourth mounting seat 541. A first insertion connector 501 is provided on the front surface of the first mandrel 50, and the first insertion connector 501 is inserted into the first insertion hole 542, causing the first mandrel 50 to extend rearward. The fourth slider 53 or the fourth movable plate 54 is driven by a fourth motor 55 to move along the extension direction of the fourth guide rail 52, thereby enabling the first mandrel 50 to enter the lower die 31 rearward or exit the lower die 31 forward.

[0039] Specifically, after the metal pen barrel is transferred to the lower die 31 of the lower stamping die 30, the first mandrel 50 can be driven by the fourth motor 55 to move backward into the die and insert into the hollow position of the metal pen barrel. This allows the first mandrel 50 to support the metal pen barrel, reducing the probability of uncontrollable deformation during the stamping, shaping, chamfering, punching, or embossing of the metal pen barrel, thereby further improving the stamping accuracy of the metal pen barrel.

[0040] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
