Description

Technical Field

[0001] This invention relates to the field of material strip cutting technology, and in particular to a material strip bending and cutting mechanism. Background Technology

[0002] The primary function of a fuse is overload protection. When a fuse is correctly positioned in a circuit, it will melt and break the circuit when the current abnormally rises to a certain level or temperature, thus protecting the circuit's safe operation.

[0003] In existing technology, the fuse core is generally made into a strip and then rolled into a roll for easy transportation. During the manufacturing process of electronic products, a section of the fuse core needs to be cut and installed inside the product, requiring the fuse core to be cut. Furthermore, because a relatively long fuse core needs to be accommodated within a limited space, it also needs to be bent before cutting. Figure 1 As shown, the material strip 11 is a straight strip with several through holes 12 and several waist-shaped grooves 13. During use, the fuse core material strip may break from the through holes 12 or from both sides of the waist-shaped grooves 13 during the loading of high current, thereby achieving the function of protecting the safe operation of the circuit.

[0004] Currently, most production lines rely on manual operation for processing. Workers need to bend the fuse core and then cut it with a special tool. This method makes it difficult to control the force during manual operation, resulting in low bending and cutting efficiency and poor product quality. Summary of the Invention

[0032] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please refer to Figures 1 to 11 The present invention provides a material strip bending and cutting mechanism.

[0034] like Figure 1 As shown, in this embodiment, the insert 21 is inserted into the through hole 12 on the material belt 11, and the insert 21 moves longitudinally, thereby driving the material belt 11 to move laterally, so as to realize the lateral feeding of the material belt 11.

[0035] like Figure 2 As shown, the material strip bending and cutting mechanism includes a frame 1. A feeding device 2, a bending device 3, and a cutting device 4 are installed side by side in the horizontal direction on the frame 1. The feeding device 2 includes a first horizontal drive assembly 22 and a first vertical drive assembly 23 mounted on the frame 1. It also includes three inserts 21 that are pulverically connected to the first horizontal drive assembly 22 and the first vertical drive assembly 23. The first vertical drive assembly 23 drives the inserts 21 to move longitudinally and inserts them into the through holes 12 on the material strip 11. The first horizontal drive assembly 22 drives the first vertical drive assembly 23 and the inserts 21 to move laterally together, thereby driving the material strip 11 to feed laterally and realizing automatic lateral feeding of the material strip 11.

[0036] The bending device 3 includes a second longitudinal drive assembly 33 mounted on the frame 1, a connecting rod 34 mounted on the frame 1, an upper bending member 31 mounted at one end and a lower bending member 32 mounted at the other end. The upper bending member 31 at one end and the lower bending member 32 at the other end of the bending device 3 are connected by the connecting rod 34 and, driven by the second longitudinal drive assembly 33, move longitudinally closer to each other to automatically bend the strip 11. The upper bending member 31 and the lower bending member 32 move synchronously through the connecting rod 34 and dock in the middle to bend the strip 11.

[0037] While bending, the next station performs cutting. Bending and cutting are performed simultaneously. The cutting device 4 includes a third longitudinal drive assembly 43 mounted on the frame 1, as well as an upper cutting component 41 and a lower cutting component 42. The lower cutting component 42 is installed inside the lower bending component 32 and is located in the middle along with the lower bending component 32. Under the longitudinal drive of the third longitudinal drive assembly 43, the upper cutting component 41 pushes the lower cutting component 42 backward to cut the strip 11 between the upper cutting component 41 and the lower cutting component 42, thus obtaining the bent finished product.

[0038] In this embodiment, the first lateral drive component 22, the first longitudinal drive component 23, the second longitudinal drive component 33, and the third longitudinal drive component 43 are arranged side by side in the lateral direction, installed together, and mechanically connected together.

[0039] In other embodiments, the first transverse drive component 22, the first longitudinal drive component 23, the second longitudinal drive component 33, and the third longitudinal drive component 43 can be independent of each other, and can be controlled in an orderly manner by the control system, or they can move together in an orderly manner to achieve transmission connection and realize automatic feeding, bending, and cutting of the material belt 11.

[0040] Furthermore, in other embodiments, the first lateral drive component 22 adopts a lateral drive cylinder, which drives laterally for a fixed distance; similarly, the first longitudinal drive component 23 adopts a first longitudinal drive cylinder, the second longitudinal drive component 33 adopts a second longitudinal drive cylinder, and the third longitudinal drive component 43 adopts a third longitudinal drive cylinder, all of which drive longitudinally for a fixed distance.

[0041] First, the control system controls the first longitudinal drive cylinder to drive the insert 21 to be inserted into the through hole 12 on the material belt 11;

[0042] Secondly, after the first longitudinal drive cylinder is in the longitudinal position, the control system controls the transverse drive cylinder to drive the first longitudinal drive cylinder and the insert 21 to move laterally together, thereby driving the material belt 11 to feed laterally. Thus, the longitudinal and transverse movements are repeated to realize the automatic transverse feeding of the material belt 11.

[0043] Next, the control system controls the second longitudinal drive cylinder to drive the upper bending member 31 to move longitudinally, and under the action of the connecting rod 34, the lower bending member 32 also moves longitudinally to bend the material strip 11.

[0044] Finally, the control system controls the third longitudinal drive cylinder to drive the upper cutting component 41 to move longitudinally, pushing the lower cutting component 42 to retract, cutting the material strip 11 to obtain the bent finished product.

[0045] like Figure 2 As shown, in this embodiment, the first lateral drive component 22, the first longitudinal drive component 23, the second longitudinal drive component 33 and the third longitudinal drive component 43 are integrated together and driven by the same drive motor 52.

[0046] Specifically, the first lateral drive assembly 22 includes a first rotating wheel 211, the first rotating wheel 211 having a first groove 212 inside, the first groove 212 having a first rotating protrusion 213 inside, and a first lateral drive block 214 fixedly mounted at one end of the first rotating protrusion 213; the first groove 212 has a lateral distance difference, thereby realizing the lateral movement of the first lateral drive block 214. In order to further ensure the stability of the lateral movement, the lower part of the first lateral drive block 214 is equipped with a first lateral slider 215 and a first lateral slide rail 216 mounted on the frame 1. The first lateral drive block 214 moves laterally back and forth on the first lateral slide rail 216 through the first lateral slider 215, thereby ensuring the stability of the lateral movement of the first lateral drive block 214.

[0047] The first longitudinal drive assembly 23 includes a second rotating wheel 221. The second rotating wheel 221 has a second groove 222 inside. The second groove 222 has a second rotating protrusion 223 inside. One end of the second rotating protrusion 223 is fixedly mounted with a first longitudinal drive block 224. The second groove 222 has a radial difference around its circumference. The second rotating protrusion 223 slides inside the second groove 222, thereby realizing the longitudinal movement of the first longitudinal drive block 224. Similarly, in order to ensure the stability of the longitudinal movement of the first longitudinal drive block 224, the lower part of the first longitudinal drive block 224 is equipped with a first longitudinal slider 227 and a first longitudinal slide rail 226 mounted on the frame 1.

[0048] Similarly, the second longitudinal drive assembly 33 includes a third rotating wheel 331, the third rotating wheel 331 has a third groove 332 inside, the third groove 332 is equipped with a third rotating protrusion 333 inside, and a second longitudinal drive block 334 is fixedly installed at one end of the third rotating protrusion 333; the third groove 332 has a radial difference in circumference, and the third rotating protrusion 333 slides inside the third groove 332, thereby realizing the longitudinal movement of the second longitudinal drive block 334. At the same time, a second longitudinal slider 337 and a second longitudinal slide rail 336 mounted on the frame 1 are installed at the lower part of the second longitudinal drive block 334.

[0049] Similarly, the third longitudinal drive assembly 43 includes a fourth rotating wheel 431, the fourth rotating wheel 431 has a fourth groove 432 inside, the fourth groove 432 is equipped with a fourth rotating protrusion 433 inside, and a third longitudinal drive block 434 is fixedly installed at one end of the fourth rotating protrusion 433; the fourth groove 432 has a radial difference in circumference, and the fourth rotating protrusion 433 slides inside the fourth groove 432, thereby realizing the longitudinal movement of the third longitudinal drive block 434. At the same time, a third longitudinal slider 437 and a third longitudinal slide rail 436 mounted on the frame 1 are installed at the lower part of the third longitudinal drive block 434.

[0050] like Figure 3 and Figure 4 As shown, the first rotating wheel 211, the second rotating wheel 221, the third rotating wheel 331, and the fourth rotating wheel 431 are all fixedly mounted on the first rotating shaft 51 and arranged laterally, rotating together with the first rotating shaft 51, and driven by a drive motor 52. The rotation of the drive motor 52 controls the first lateral drive block 214, the first longitudinal drive block 224, the second longitudinal drive block 334, and the third longitudinal drive block 434 to move together in an orderly manner, thereby realizing the orderly movement of each action and realizing their respective lateral and longitudinal movements.

[0051] like Figure 5 and Figure 6 As shown, the feeding device 2 also includes a transverse moving block 24 mounted on the frame 1. The transverse moving block 24 is connected to the first transverse driving assembly 22. In this embodiment, the transverse moving block 24 is not fixedly connected to the first transverse driving block 214, and a reset elastic element 27 is used for reset. In other embodiments, the transverse moving block 24 can be fixedly connected to the first transverse driving block 214 and move laterally together. To ensure the stability of the transverse movement of the first transverse driving block 214, a slider and a slide rail are also used in cooperation.

[0052] like Figure 5 and Figure 6 As shown, a first longitudinal moving block 25 is installed above the transverse moving block 24. The first longitudinal moving block 25 is connected to the first longitudinal driving component 23. In order to ensure the stability of the transverse movement of the first longitudinal moving block 25, a slider and a slide rail are also used in cooperation.

[0053] like Figure 5 and Figure 6 As shown, the first longitudinal moving block 25 is equipped with an insert 21 at its end; the three inserts 21 can ensure that there is an equal lateral distance between the two ends inside; the first longitudinal driving component 23 drives the insert 21 to be longitudinally inserted into the material belt 11, and moves laterally under the drive of the first lateral driving component 22, thereby driving the material belt 11 to feed laterally.

[0054] Specifically, the transmission connection between the first longitudinal drive component 23 and the first longitudinal moving block 25 is as follows: Figure 6As shown, the first longitudinal moving block 25 has a first U-shaped groove 251 at its end, and the first longitudinal driving block 224 has a fifth rotating protrusion 225 at its end away from the second rotating protrusion 223. The fifth rotating protrusion 225 is installed inside the first U-shaped groove 251. The first longitudinal driving block 224 is connected to the first longitudinal moving block 25 through the fifth rotating protrusion 225. The fifth rotating protrusion 225 is inside the first U-shaped groove 251, so that the first longitudinal moving block 25 and the first longitudinal driving block 224 reciprocate longitudinally together.

[0055] In this embodiment, since the first longitudinal moving block 25 also needs to move laterally a certain distance, the first U-shaped groove 251 has a relatively long lateral length to satisfy the lateral movement and also to ensure that the fifth rotating protrusion 225 will not detach from the interior of the first U-shaped groove 251.

[0056] Specifically, the transmission connection between the first lateral drive component 22 and the lateral moving block 24 is as follows: Figure 6 As shown, the first lateral drive assembly 22 and the lateral moving block 24 are not directly connected, but they are kinematically connected. The lateral moving block 24 is mounted on one side of the first lateral drive block 214. Furthermore, a first mounting rod 15 is mounted on the frame 1, and a second mounting rod 26 is mounted on the lateral moving block 24. A reset elastic element 27 for resetting the lateral moving block 24 is installed between the first mounting rod 15 and the second mounting rod 26. Further, when the first lateral drive block 214 pushes the lateral moving block 24 to move laterally forward, the reset elastic element 27 is stretched and stores elastic potential energy. When lateral reset is required, the reset elastic element 27 drives the lateral moving block 24 to reset.

[0057] like Figure 5 and Figure 6 As shown, the feeding device 2 further includes a feeding auxiliary block 241 installed at the end of the transverse moving block 24. The feeding auxiliary block 241 is provided with a limiting groove 242 for transverse feeding of the material belt 11. The material belt 11 passes transversely through the inside of the limiting groove 242. The feeding auxiliary block 241 is provided with three transversely arranged insertion holes 243. The insert 21 passes through the insertion holes 243 and is inserted into the material belt 11 inside the limiting groove 242 to connect with the material belt 11, thereby driving the material belt 11 to feed transversely.

[0058] like Figure 5 and Figure 6As shown, the transverse moving block 24 has a sixth groove 244 for installing the insert 21. The end of the insert 21 extends outward through the sixth groove 244 and is inserted into the insertion hole 243 to connect with the material belt 11. The sixth groove 244 has a longitudinal travel, and the insert 21 can slide longitudinally back and forth inside the sixth groove 244.

[0059] The sixth groove 244 is also equipped with a first elastic element 245 for driving the insert 21 to extend outward. The first elastic element 245 is a spring and has a certain elastic potential energy inside, which can firmly press the insert 21 and make the insert 21 extend outward stably. When the insert 21 needs to be replaced, it is only necessary to take out the first elastic element 245 and the insert 21 in sequence to replace it.

[0060] like Figure 5 and Figure 6 As shown, the sixth groove 244 has an eighth groove 246 on its side. The insert 21 is threaded with a drive rod 247 for driving the longitudinal movement of the insert 21. The drive rod 247 is inserted into the insert 21 and fixedly connected by threads. When the material strip 11 needs to be initially installed or replaced, the drive rod 247 can be manually moved longitudinally backward, so that the insert 21 moves longitudinally backward together and compresses the first elastic element 245. After a certain distance, the drive rod 247 is rotated to lock the drive rod 247 into the eighth groove 246. This achieves the backward fixation of the insert 21, thus providing space and time to manually install the material strip 11 into the limiting groove 242, thereby achieving the manual initial installation of the material strip 11.

[0061] In this embodiment, a linkage bending method is adopted: that is, the upper bending part 31 and the lower bending part 32 move towards the middle together synchronously, thereby bending the middle strip 11. Correspondingly, the upper bending part 31 and the lower bending part 32 are provided with mutually cooperating curved arc surfaces 39.

[0062] like Figure 7 As shown, the bending device 3 further includes a second longitudinal moving block 35 and a third longitudinal moving block 36 mounted on the frame 1. An upper bending member 31 is fixedly mounted on the second longitudinal moving block 35, and a lower bending member 32 is fixedly mounted on the third longitudinal moving block 36. Both the second longitudinal moving block 35 and the third longitudinal moving block 36 require longitudinal reciprocating motion. Therefore, to ensure the stability of the longitudinal movement of the second longitudinal moving block 35 and the third longitudinal moving block 36, a slider and a slide rail are used in conjunction to limit the movement of the second longitudinal moving block 35 and the third longitudinal moving block 36.

[0063] like Figure 7 and Figure 8As shown, the specific method of transmission connection between the second longitudinal drive assembly 33 and the second longitudinal moving block 35 is as follows: the end of the second longitudinal moving block 35 is provided with a second U-shaped groove 351, and the end of the second longitudinal drive block 334 away from the third rotating protrusion 333 is provided with a sixth rotating protrusion 335, which is installed inside the second U-shaped groove 351; the second longitudinal drive block 334 is transmissionally connected to the second longitudinal moving block 35 through the sixth rotating protrusion 335, which is installed inside the second U-shaped groove 351, so that the second longitudinal moving block 35 and the second longitudinal drive block 334 reciprocate longitudinally together.

[0064] The specific method of linkage between the second longitudinal moving block 35 and the third longitudinal moving block 36 is as follows: the end of the second longitudinal moving block 35 away from the second U-shaped groove 351 is provided with a third U-shaped groove 352, and the end of the third longitudinal moving block 36 is provided with a fourth U-shaped groove 361. The connecting rod 34 is connected to the frame 1 through the second rotating shaft 38 and rotates around the second rotating shaft 38. One end of the connecting rod 34 is provided with a seventh rotating protrusion 341 for installation inside the third U-shaped groove 352, and the other end is provided with an eighth rotating protrusion 342 for installation inside the fourth U-shaped groove 361. The second longitudinal moving block 35 and the third longitudinal moving block 36 are separated from each other or brought closer together by the connecting rod 34.

[0065] When bending is required, the second longitudinal drive block 334 drives the second longitudinal moving block 35 to move closer to the center, and the second longitudinal moving block 35 drives the connecting rod 34 to rotate clockwise around the second rotating shaft 38; the connecting rod 34 drives the third longitudinal moving block 36 to move closer to the center, thereby bending the strip 11 between the second longitudinal moving block 35 and the third longitudinal moving block 36; when moving away is required, the second longitudinal drive block 334 drives the second longitudinal moving block 35 to move away from the center, and the second longitudinal moving block 35 drives the connecting rod 34 to rotate counterclockwise around the second rotating shaft 38; the connecting rod 34 drives the third longitudinal moving block 36 to move away from the center, thereby separating the second longitudinal moving block 35 and the third longitudinal moving block 36 from each other.

[0066] In other embodiments, two longitudinal cylinders can be used to drive the second longitudinal moving block 35 and the third longitudinal moving block 36 respectively, and the control system can control the two longitudinal cylinders to move closer to each other or move further away from each other at the same time.

[0067] To allow for longitudinal fine-tuning of the upper bending member 31 and the lower bending member 32, the upper bending member 31 is provided with a first U-shaped groove 311, and the lower bending member 32 is provided with a second U-shaped groove 321; both the first U-shaped groove 311 and the second U-shaped groove 321 are longitudinally U-shaped; Figure 8 and Figure 9As shown, the adjusting bolts can be adjusted longitudinally at the positions of the first U-groove 311 and the second U-groove 321. To more accurately adjust the longitudinal positions of the upper bending member 31 and the lower bending member 32, the second longitudinal movement block 35 is equipped with a first adjusting knob 371 for adjusting the longitudinal position of the upper bending member 31, and the third longitudinal movement block 36 is equipped with a second adjusting knob 372 for adjusting the longitudinal position of the lower bending member 32. Both the first adjusting knob 371 and the second adjusting knob 372 use micrometer screw gauges, which have high adjustment accuracy, indirectly resulting in high precision and consistency of the bent strip 11, thereby improving the quality of the finished product.

[0068] In this embodiment, the cutting device 4 is the next station after bending, but it cuts the material strip 11 at the same time as bending, and the two happen simultaneously; at the same time, there is a continuous feed of transverse material strip 11.

[0069] like Figure 9 As shown, the cutting device 4 also includes a fourth longitudinal moving block 44 mounted on the frame 1. An upper cutting component 41 is fixedly mounted on the fourth longitudinal moving block 44. The fourth longitudinal moving block 44 needs to move longitudinally back and forth. Therefore, in order to ensure the stability of the longitudinal movement of the fourth longitudinal moving block 44, a slider and a slide rail are used to cooperate to limit the fourth longitudinal moving block 44.

[0070] like Figure 9 As shown, the specific method of transmission connection between the third longitudinal drive component 43 and the fourth longitudinal moving block 44 is as follows: the fourth longitudinal moving block 44 is provided with a fifth U-shaped groove 441 at its end, and the third longitudinal drive block 434 is provided with a ninth rotating protrusion 435 at its end away from the fourth rotating protrusion 433. The ninth rotating protrusion 435 is installed inside the fifth U-shaped groove 441 and is used to drive the fourth longitudinal moving block 44 to move longitudinally. The third longitudinal drive block 434 is connected to the fourth longitudinal moving block 44 through the ninth rotating protrusion 435. The ninth rotating protrusion 435 is installed inside the fifth U-shaped groove 441, so that the fourth longitudinal moving block 44 and the third longitudinal drive block 434 move longitudinally reciprocally together.

[0071] like Figure 9 As shown, the lower cutting component 42 is mounted on the third longitudinal moving block 36 and moves longitudinally reciprocally together with the third longitudinal moving block 36; specifically, the third longitudinal moving block 36 is provided with a sliding groove 45 for mounting the lower cutting component 42, and the lower cutting component 42 can also move longitudinally reciprocally inside the sliding groove 45, thereby cutting the material strip 11.

[0072] like Figure 9 and Figure 10As shown, the sliding groove 45 is further equipped with a second elastic element 451 for driving the lower cutting component 42. One end of the lower bending component 32 is provided with a fifth groove 322 for accommodating the end of the lower cutting component 42. The second elastic element 451 drives the lower cutting component 42 to move longitudinally and insert into the fifth groove 322. The second elastic element 451 is a spring with a certain elastic potential energy, which can firmly press the lower cutting component 42, ensuring its stable insertion into the fifth groove 322 and longitudinal movement together with the lower bending component 32.

[0073] When the strip 11 needs to be cut, the third longitudinal drive block 434 drives the fourth longitudinal motion block 44 to move longitudinally together. At this time, the upper cutting component 41 moves closer to the lower cutting component 42, while simultaneously driving the lower cutting component 42 to move longitudinally backward, compressing the second elastic element 451 and cutting the strip 11 to obtain the bent finished product. After the upper cutting component 41 returns to its original position, the second elastic element 451 drives the lower cutting component 42 to move longitudinally and insert into the fifth groove 322, also returning to its initial position.

[0074] To facilitate better insertion of the lower cutting component 42 into the lower bending component 32 and to limit the lower cutting component 42, the lower cutting component 42 is provided with an insertion part 421 that inserts into the fifth groove 322 and a limiting protrusion 422 for limiting the lower cutting component 42. The limiting protrusion 422 is provided on one side of the lower bending component 32. Under the drive of the second elastic member 451, the insertion part 421 is inserted into the fifth groove 322. At the same time, the limiting protrusion 422 also limits the stroke of the lower cutting component 42, so that the lower cutting component 42 will not detach from the lower bending component 32.

[0075] like Figure 10 and Figure 11 As shown, the upper bending member 31 is provided with a seventh groove 312 for accommodating the end of the upper cutting member 41. Specifically, during cutting, the end of the upper cutting member 41 is inserted into the seventh groove 312. Furthermore, the end of the upper cutting member 41 is also provided with a receiving groove 411 for accommodating the insertion part 421. The longitudinal width of the insertion part 421 is the same as or slightly larger than the longitudinal width of the strip 11, allowing the insertion part 421 to accommodate the strip 11, thus enabling precise cutting. Even further, guide blocks 412 are provided on both sides of the receiving groove 411. The guide blocks 412 are inserted into both sides of the insertion part 421, guiding the insertion part 421 into the receiving groove 411 and longitudinally limiting the strip 11, thus enabling precise cutting. The insertion part 421 and the receiving groove 411 move longitudinally together to cut the strip 11.

[0076] To further improve the fitting accuracy between the lower bending member 32 and the upper bending member 31, and also to improve the subsequent cutting accuracy, the lower bending member 32 is provided with a lower protrusion 323, and the upper bending member 31 is provided with an upper groove 313 that mates with the lower protrusion 323. When the lower bending member 32 and the upper bending member 31 approach each other, the lower protrusion 323 is inserted into the upper groove 313, and the two fit tightly together, realizing the fit between the lower bending member 32 and the upper bending member 31, and improving the bending accuracy and cutting accuracy.

[0077] To allow for longitudinal fine-tuning of the upper cutting component 41, a third U-shaped groove 413 is provided on the upper cutting component 41, the third U-shaped groove 413 being longitudinally U-shaped; for example Figure 9 As shown, the adjusting bolt can be adjusted longitudinally at the position of the third U-shaped groove 413; in order to adjust the longitudinal position of the upper cutting component 41 more precisely, the fourth longitudinal moving block 44 is equipped with an adjusting bolt 414 for adjusting the longitudinal position of the upper cutting component 41. The adjusting bolt 414 has high adjustment accuracy, which indirectly makes the material strip 11 have high cutting accuracy and high consistency, thereby improving the quality of the finished product.

[0078] The operating steps of the strip bending and cutting mechanism are as follows:

[0079] Step S1: Manually feed the material strip 11, manually move the drive rod 247 longitudinally backward, causing the insert 21 to retract longitudinally as well, and compress the first elastic member 245. After a certain distance, rotate the drive rod 247 to lock the drive rod 247 inside the eighth groove 246; thereby achieving the retraction and fixation of the insert 21, and manually installing the material strip 11 inside the limiting groove 242, manually installing the initial end of the material strip 11 into place.

[0080] In step S2, after the drive rod 247 leaves the eighth groove 246, the first elastic member 245 drives the insert 21 to move longitudinally, so that the end of the insert 21 extends outward through the sixth groove 244.

[0081] In step S3, the drive motor 52 drives the first rotating shaft 51 to rotate, and the first rotating wheel 211, the second rotating wheel 221, the third rotating wheel 331 and the fourth rotating wheel 431 fixedly mounted on the first rotating shaft 51 rotate together. The first rotating wheel 211 controls the first transverse drive block 214 to reciprocate laterally, the second rotating wheel 221 controls the first longitudinal drive block 224 to reciprocate longitudinally, the third rotating wheel 331 controls the second longitudinal drive block 334 to reciprocate longitudinally, and the fourth rotating wheel 431 controls the third longitudinal drive block 434 to reciprocate longitudinally.

[0082] In step S4, the first longitudinal drive block 224 drives the first longitudinal motion block 25 to move longitudinally together, and drives the insert 21 to be inserted into the through hole 12 on the material belt 11 to connect with the material belt 11.

[0083] In step S5, the first transverse drive block 214 drives the transverse motion block 24 to move laterally, moving the first longitudinal motion block 25, the insert 21, and the material belt 11 together laterally, thereby achieving automatic transverse feeding of the material belt 11. Subsequently, the first longitudinal motion block 25 is reset by the drive of the first longitudinal drive block 224, and the transverse motion block 24 is reset using the reset elastic element 27. In this way, repeated movements achieve continuous transverse feeding of the material belt 11.

[0084] In step S6, the second longitudinal drive block 334 drives the second longitudinal motion block 35 to move closer to the center, and the second longitudinal motion block 35 drives the connecting rod 34 to rotate clockwise around the second rotating shaft 38; the connecting rod 34 drives the third longitudinal motion block 36 to move closer to the center, thereby bending the material strip 11 between the second longitudinal motion block 35 and the third longitudinal motion block 36.

[0085] In step S7, the second longitudinal moving block 35 and the third longitudinal moving block 36 are in the middle, and the lower protrusion 323 is inserted into the upper groove 313, with the two fitting tightly together. At the same time, the lower cutting component 42 is also in the middle, and the third longitudinal driving block 434 drives the upper cutting component 41 on the fourth longitudinal moving block 44. The upper cutting component 41 moves longitudinally, and the guide block 412 is inserted into both sides of the insertion part 421, guiding the insertion part 421 into the receiving groove 411 and longitudinally limiting the material strip 11. The lower cutting component 42 is driven to move longitudinally backward, compressing the second elastic member 451 and cutting the material strip 11 to obtain the bent finished product. Subsequently, the second elastic member 451 resets the lower cutting component 42, and the third longitudinal driving block 434 drives the upper cutting component 41 to reset.
