Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a multi-station plastic wire bending machine. Background Technology

[0002] Plastic wires are thin, long strips made of plastic, commonly used to manufacture products such as plastic ropes, nets, strips, and pipes. Common plastic wires include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polystyrene (PS). Due to their lightweight, corrosion resistance, and good insulation properties, plastic wires are widely used in electronics, electrical engineering, construction, and automotive industries. However, in practical applications, plastic wires often need to be bent according to design requirements to adapt to different installation environments and usage needs, thus requiring the use of bending machines to perform this bending process.

[0003] An existing patent (application number 202220786133.6) discloses a plastic tube bending device, including a positioning assembly. The positioning assembly is equipped with a bending mechanism. The positioning assembly includes a support platform, and two first screws are rotatably connected inside the support platform. Each of the two first screws has an adjusting plate with one end penetrating through and extending above the support platform. A positioning seat is fixedly installed on the top of the adjusting plate. The top of the positioning seat has a mounting hole, and a fixing plate is fixedly installed inside the mounting hole. A second screw with one end penetrating through and extending into the positioning seat is rotatably connected to the top of the fixing plate. This plastic tube bending device, by setting the positioning assembly, can clamp and position plastic tubes of different lengths and thicknesses, thereby facilitating the bending mechanism to bend plastic tubes of different sizes, improving the efficiency of plastic tube bending and the applicability of the device, and making it convenient for users to operate.

[0004] Existing bending machines are difficult to bend multiple workpieces at the same time. A bending machine can only process one workpiece at a time, which not only results in relatively low work efficiency, but also makes it inconvenient to manually remove the workpiece after it is bent in the bending seat. Utility Model Content

[0005] Therefore, it is necessary to provide a multi-station plastic wire bending machine to address the technical problems that bending machines cannot simultaneously bend multiple plastic wires, and that after the plastic wires are bent in the bending seat, they are not well ejected, making manual removal inconvenient.

[0006] A multi-station plastic wire bending machine includes a bending worktable. Support legs are fixedly installed on the lower left and lower right sides of the bending worktable. An ejector device is fixedly installed at one end of each of the two support legs. A controller is fixedly installed on the front right side of the bending worktable. A support frame is movably installed on the upper left and upper right sides of the bending worktable. A bending device is fixedly installed on the upper left and upper right sides of the support frame. Five bending seats are fixedly installed on the front upper part of the bending worktable. Guide devices are fixedly installed at the front and rear ends of the five bending seats. A servo motor is fixedly installed on the left front end of the bending worktable. The bending device includes two hydraulic cylinders. A connecting seat is fixedly installed at the output ends of the two hydraulic cylinders. Five bending heads are fixedly installed at the lower end of the connecting seat. The two hydraulic cylinders are respectively inserted and fixedly installed on the upper left and upper right sides of the support frame.

[0007] In one embodiment, a first slider is fixedly installed on the lower right side of the support frame, a second slider is fixedly installed on the lower left side of the support frame, a first groove is opened on the upper right side of the bending worktable, a second groove is opened on the upper left side of the bending worktable, the first slider is slidably installed in the first groove, the second slider is slidably installed in the second groove, and a threaded rod is fixedly installed at the output end of the servo motor.

[0008] The servo motor drives the threaded rod to rotate in the second slide groove. At this time, the second slider on the threaded rod slides in the second slide groove, thereby adjusting the position of the support frame so that the bending head can be aligned with the forming groove. Then, the two hydraulic cylinders push the connecting seat downward, and the connecting seat pushes the bending head downward. The bending head presses the middle part of the tubular plastic wire into the forming groove, so that the plastic wire can be bent into shape.

[0009] In one embodiment, the ejection device includes a fixed base, with an electric telescopic rod inserted and fixedly installed on both the upper left and upper right sides of the fixed base. The output ends of the two electric telescopic rods are jointly fixedly installed with a top plate. Several lifting columns are fixedly installed on the upper end of the top plate, and the fixed base is fixedly installed between two support legs.

[0010] The bending worktable has perforations that allow the lifting column to pass through the perforations to the ejection slot. Therefore, by pushing the top plate upward with two electric telescopic rods, the lifting column on the top plate passes through the bending worktable and inserts into the bending seat through the ejection slot, thereby ejecting the bent plastic wire from the bending seat and facilitating the unloading of the plastic wire.

[0011] In one embodiment, each of the five bending seats has a placement groove at the front and rear of its upper end, a forming groove at the middle of its upper end, and three ejection grooves at the lower end of its lower end.

[0012] The device is equipped with multiple bending seats and bending heads, which allows it to hold multiple plastic wires at once and bend them simultaneously, thereby improving the processing efficiency of the device.

[0013] In one embodiment, the guiding device includes a first guide seat and a second guide seat, each with five push slots on its upper end. The first guide seat is fixedly installed at the front end of the five bending seats, and the second guide seat is fixedly installed at the rear end of the five bending seats.

[0014] Place the tubular plastic wire into the push groove on the first or second guide seat of the guide device. The tubular plastic wire in the push groove can then be pushed into the placement groove on the bending seat, which facilitates the rapid and accurate feeding of the tubular plastic wire.

[0015] In one embodiment, both the first slider and the second slider are in the shape of an I-shape.

[0016] In one embodiment, the threaded rod is rotatably mounted in the second slide groove, and the second slider is threadedly mounted on the threaded rod.

[0017] In one embodiment, a number of the lifting columns are arranged in a rectangular row on the top plate, and the lifting columns are vertically aligned with the positions of the ejector slots.

[0018] In one embodiment, the controller is electrically connected to the servo motor, the hydraulic cylinder, and the electric telescopic rod.

[0019] In one embodiment, the pushing groove and the placement groove are the same size and their positions correspond to each other.

[0020] The aforementioned multi-station plastic wire bending machine, when requiring bending of plastic wire, first places the tubular plastic wire in the push groove of either guide seat number one or guide seat number two on the guiding device. This pushes the tubular plastic wire into the placement groove on the bending seat, facilitating rapid and precise feeding. Next, a servo motor drives a threaded rod to rotate in the second sliding groove. Simultaneously, the second slider on the threaded rod slides within the second sliding groove, adjusting the position of the support frame so that the bending head aligns with the forming groove. Then, two hydraulic cylinders push the connecting seat downwards, which in turn pushes the bending head downwards, thus bending the tubular plastic wire... The material is pressed down into the forming groove, allowing the plastic wire to be bent into shape. Multiple bending seats and bending heads are provided, enabling the device to hold multiple plastic wires at once and bend them simultaneously, thus improving processing efficiency. After bending, the servo motor drives the threaded rod, causing the support frame to slide backward, exposing the upper space of the plastic wire. At this point, two electric telescopic rods on the ejector device push the top plate upward, causing the lifting column on the top plate to pass through the bending worktable and insert into the bending seat through the ejection groove, thus ejecting the bent plastic wire from the bending seat and facilitating the unloading of the plastic wire.

[0031] Please refer to the following: Figures 1 to 5 This utility model provides a multi-station plastic wire bending machine, including a bending workbench 1. Support legs 6 are fixedly installed on the lower left and lower right sides of the bending workbench 1. An ejector device 3 is fixedly installed on one end of each of the two support legs 6. A controller 8 is fixedly installed on the front right side of the bending workbench 1. A support frame 7 is movably installed on the upper left and upper right sides of the bending workbench 1. A bending device 2 is fixedly installed on the upper left and upper right sides of the support frame 7. Five bending seats 4 are fixedly installed on the front upper side of the bending workbench 1. Guide devices 5 are fixedly installed on the front and rear ends of the five bending seats 4. A servo motor 9 is fixedly installed on the left front side of the bending workbench 1. The bending device 2 includes two hydraulic cylinders 20. A connecting seat 21 is fixedly installed on the output ends of the two hydraulic cylinders 20. Five bending heads 22 are fixedly installed on the lower end of the connecting seat 21. The two hydraulic cylinders 20 are respectively inserted and fixedly installed on the upper left and upper right sides of the support frame 7.

[0032] A first slider 23 is fixedly installed on the lower right side of the support frame 7, and a second slider 24 is fixedly installed on the lower left side of the support frame 7. A first groove 25 is opened on the upper right side of the bending worktable 1, and a second groove 26 is opened on the upper left side of the bending worktable 1. The first slider 23 is slidably installed in the first groove 25, and the second slider 24 is slidably installed in the second groove 26. A threaded rod 27 is fixedly installed at the output end of the servo motor 9. The first slider 23 and the second slider 24 are both I-shaped. The threaded rod 27 is rotatably installed in the second groove 26, and the second slider 24 is threadedly installed on the threaded rod 27.

[0033] The servo motor 9 drives the threaded rod 27 to rotate in the second slide groove 26. At this time, the second slider 24 on the threaded rod 27 slides in the second slide groove 26, thereby adjusting the position of the support frame 7 so that the bending head 22 can be aligned with the forming groove 40. Then, the two hydraulic cylinders 20 push the connecting seat 21 downward, and the connecting seat 21 pushes the bending head 22 downward. The bending head 22 presses the middle part of the tubular plastic wire into the forming groove 40, so that the plastic wire can be bent into shape.

[0034] The ejection device 3 includes a fixed base 30. Electric telescopic rods 31 are inserted and fixedly installed on the upper left and upper right sides of the fixed base 30. The output ends of the two electric telescopic rods 31 are fixedly installed on a top plate 32. Several lifting columns 33 are fixedly installed on the upper end of the top plate 32. The fixed base 30 is fixedly installed between two support legs 6.

[0035] The bending worktable 1 has a through hole, allowing the lifting column 33 to pass through the through hole to the ejection slot 41. Therefore, by pushing the top plate 32 upward with the two electric telescopic rods 31, the lifting column 33 on the top plate 32 passes through the bending worktable 1 and inserts into the bending seat 4 through the ejection slot 41, thereby ejecting the bent plastic wire in the bending seat 4, which facilitates the unloading of the plastic wire. The controller 8 is electrically connected to the servo motor 9, the hydraulic cylinder 20 and the electric telescopic rods 31.

[0036] Each of the five bending seats 4 has a placement groove 42 at the front and rear of its upper end, a forming groove 40 at the middle of its upper end, and three ejection grooves 41 at the lower end.

[0037] Multiple bending seats 4 and bending heads 22 are provided, so that the device can place multiple plastic wires at one time and bend these plastic wires at the same time, thereby improving the processing efficiency of the device; several lifting columns 33 are arranged in a rectangular row on the top plate 32, and the lifting columns 33 correspond vertically to the positions of the ejection grooves 41.

[0038] The guiding device 5 includes a first guide seat 50 and a second guide seat 51. Both the first guide seat 50 and the second guide seat 51 have five pushing grooves 52 on their upper ends. The first guide seat 50 is fixedly installed at the front end of the five bending seats 4, and the second guide seat 51 is fixedly installed at the rear end of the five bending seats 4. The pushing grooves 52 and the placement grooves 42 have the same size and are positioned in a corresponding manner.

[0039] The tubular plastic wire is placed in the push groove 52 on the first guide seat 50 or the second guide seat 51 on the guide device 5. At this time, the tubular plastic wire in the push groove 52 can be pushed into the placement groove 42 on the bending seat 4, which facilitates the rapid and accurate feeding of the tubular plastic wire.

[0040] This utility model provides a multi-station plastic wire bending machine. Before use, the controller 8 is first connected to an external power supply. Then, the tubular plastic wire is placed in the push groove 52 on the first guide seat 50 or the second guide seat 51 of the guide device 5. At this time, the tubular plastic wire in the push groove 52 can be pushed into the placement groove 42 on the bending seat 4, which facilitates the rapid and accurate feeding of the tubular plastic wire. Then, the servo motor 9 drives the threaded rod 27 to rotate in the second slide groove 26. At this time, the second slider 24 on the threaded rod 27 slides in the second slide groove 26, thereby adjusting the position of the support frame 7 so that the bending head 22 can be aligned with the forming groove 40. Then, the two hydraulic cylinders 20 push the connecting seat 21 downward, and the connecting seat 21 pushes the bending head 22 downward, bending... The elbow 22 presses the middle part of the tubular plastic wire into the forming groove 40, allowing the plastic wire to be bent and formed. Multiple bending seats 4 and bending heads 22 are provided, allowing the device to place multiple plastic wires at once and bend them simultaneously, thereby improving the processing efficiency of the device. After the plastic wire is bent, the servo motor 9 drives the threaded rod 27, causing the support frame 7 to slide backward, exposing the upper space of the plastic wire. At this time, the two electric telescopic rods 31 on the ejection device 3 push the top plate 32 upward, and the lifting column 33 on the top plate 32 passes through the bending worktable 1 and inserts into the bending seat 4 through the ejection groove 41, thereby ejecting the bent plastic wire in the bending seat 4, which facilitates the unloading of the plastic wire.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
