Description

Technical Field

[0001] The invention relates to the technical field of metal wire material processing, and in particular to a positionable bending and forming device for a flexible flat wire. Background Art

[0002] Flat wire bending and forming refers to bending and shaping flat wires according to design requirements through specific molds and processes to make them conform to specific geometric shapes and sizes. The main purpose of bending and forming is to meet the needs of different application scenarios, such as optimizing space utilization, improving electrical performance, enhancing structural strength or adapting to specific installation environments. Through bending and forming, the stability and reliability of the product can be improved, while simplifying the assembly process and reducing costs.

[0003] For example, in the process of bending and shaping the corners of the two ends of the flexible enameled flat copper wire vertical winding coil, ordinary bending machines fail to fully consider the flexibility and elastic properties of the flexible flat copper wire itself, lack precise positioning and shaping functions, resulting in partial rebound of the bent product, which in turn causes the shape of the formed product to deviate from the designed size, seriously affecting the accuracy and quality of the product.

[0004] Based on the above situation, the present invention provides a positionable bending and forming device for a flexible flat wire. Summary of the invention

[0011] In a preferred embodiment of the present invention, the pressure plate contacts the guide frame when moving toward a side close to the pressure plate.

[0012] In a preferred embodiment of the present invention, it also includes an arc-shaped push block, which is fixedly connected to the bending frame, and the limit frame is slidably connected to a slide, and the slide is fixedly connected to the blocking frame. A side of the slide close to the arc-shaped push block is set as a wedge-shaped surface, and when the arc-shaped push block rotates one hundred and eighty degrees, the wedge-shaped surface squeezes the slide to slide upward.

[0013] In a preferred embodiment of the present invention, a partition block is further included, the partition block is slidably connected to the bending frame, the partition block is in contact with the cylindrical surface of the pressure plate, and a spring is fixedly connected between the partition block and the bending frame.

[0017] The present invention uses the cylindrical surface of the pressure plate to squeeze and cooperate with the guide frame, so that the pressure plates on the left and right sides automatically slide upward, achieving the effect of pressing the rear semicircular ring part of the coil on the left and right sides. In this way, the coil can be further maintained in a shaped state after being removed.

[0018] The invention drives the arc-shaped push block to rotate when the bending frame rotates, so that the slide frame assists the blocking frame to slide upward, so that the coil can pass over the blocking frame and the coil can be prevented from being deformed.

[0019] When the bottom of the pressure plate just moves up to the height of the second guide groove, the partition block is driven to move forward by the spring reset, thereby assisting in pushing the pressure plate to move forward and separate from the magnet. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0032] Embodiment 1: A positionable bending and forming device for a flexible flat wire, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Fig. 9 As shown, it includes a mounting frame 1, a servo motor 2 is fixedly connected to the front side of the mounting frame 1, a bending frame 3 is fixedly connected to the output shaft of the servo motor 2, the bending frame 3 is used to bend the flexible flat wire 301, a limiting frame 4 is fixedly connected to the left side of the rear side of the mounting frame 1, a discharge groove 401 is opened on the upper part of the limiting frame 4, an arc-shaped bending groove 402 is opened on the upper left side of the bending frame 3, the bending groove 402 and the discharge groove 401 are located on the same horizontal line, the bending frame 3 is provided with an arc surface 403 on the rear side near the bending groove 402, and the upper right part of the limiting frame 4 A baffle frame 5 is connected for sliding along the up-down direction, and the end face of the right side of the baffle frame 5 is set as an inclined surface. A pressure plate 6 is inserted into the side of the bending frame 3 close to the bending groove 402 along the up-down direction. The upper and lower parts of the pressure plate 6 are respectively set to a disc shape and a cylinder shape. A first tension spring 8 is fixedly connected to the side of the bending frame 3 close to the pressure plate 6, and a magnet 7 is fixedly connected to the top of the first tension spring 8. The pressure plate 6 and the magnet 7 are magnetically attracted to each other. A baffle rod 9 is connected for sliding along the up-down direction on the side of the pressure plate 6 close to the bending groove 402, and a second tension spring 10 is fixedly connected between the baffle rod 9 and the pressure plate 6.

[0033] Initially, the pressure plate 6 is attracted by the magnet 7, the first tension spring 8 is in a natural state, and the second tension spring 10 is in a stretched state. When using the device, the flexible flat wire 301 is first pushed forward by the feeding device of the bending machine, and the flexible flat wire 301 extends forward into the bending groove 402 after coming out of the discharge groove 401, and then extends the head end forward from the bending groove 402. The feeding component is paused, during which the head end of the flexible flat wire 301 is bent upward and tilted, and then the feeding component continues to push the flexible flat wire 301 forward, so that the flexible flat wire extends from the bending groove 402 to the desired position. The length required, at this time, the feeding assembly is paused, and the output shaft of the servo motor 2 drives the bending frame 3 to rotate 180 degrees counterclockwise, and the bending frame 3 drives the bending groove 402 to rotate 180 degrees counterclockwise, and the bending groove 402 cooperates with the arc surface 403 to bend the side of the flexible flat wire 301 close to the bending groove 402 into a semicircular ring portion, and the head end of the flexible flat wire 301 rotates 180 degrees and faces the right rear side, and then the output shaft of the servo motor 2 drives the bending frame 3 to rotate 180 degrees clockwise to reset, so that the bending groove 402 is rotated clockwise along the bent semicircular ring portion of the flexible flat wire 301. The needle rotates 180 degrees to reset, then the feeding assembly continues to push the flexible flat wire 301 forward, so that the flexible flat wire extends out of the bending groove 402 to the required length again. During this process, the bent semicircular ring portion moves forward away from the bending groove 402, then the feeding assembly pauses, and the output shaft of the servo motor 2 drives the bending frame 3 to rotate 180 degrees counterclockwise again, and the bending frame 3 drives the bending groove 402 to rotate 180 degrees counterclockwise, and the side of the flexible flat wire 301 close to the bending groove 402 is bent into a new semicircular ring portion. During this process, the previous semicircular ring portion rotates After turning 180 degrees to the rear end, the head end of the flexible flat wire 301 continues to rotate 180 degrees toward the left front side, and the upwardly bent and raised part of the head end of the flexible flat wire 301 will be squeezed between the top of the bending frame 3 and the pressure plate 6. In this way, the flexible flat wire 301 completes one circle of bending and forming operation, and the subsequent feeding assembly and the bending frame 3 intermittently feed and bend the flexible flat wire 301 without interruption, so that it can be bent into multiple circles of longitudinally stacked coils, and the front and rear ends of the formed coil product have semicircular structures, and the left and right sides in the middle have straight strip structures.

[0034] In the above process, as the number of coils of the flexible flat wire 301 increases, the pressure plate 6 is pushed upward progressively, the pressure plate 6 pulls the magnet 7 to move upward progressively, the first tension spring 8 is progressively stretched, and the second tension spring 10 gradually rebounds. In this way, the pressure plate 6 always presses the bent and formed coil from the top downward. At the same time, the stop rod 9 limits and shapes the formed coil from the left front side, the limit frame 4 limits and shapes the formed coil from the left rear side, and the stop frame 5 limits and shapes the formed coil from the right rear side, so as to enhance the shape memory function of the formed coil, prevent the coil from rebounding to a certain extent after bending and forming, and improve the forming effect.

[0035] Embodiment 2: Based on embodiment 1, Figure 4-Figure 6 As shown, a slide groove 11 is provided at the lower part of the pressure plate 6, and a bidirectional elastic telescopic frame 12 is slidably connected in the slide groove 11 along the up and down directions. The bending frame 3 is provided with a first guide groove 121 symmetrically distributed along the bending frame 3, and the front and rear sides of the first guide groove 121 are respectively composed of a horizontal portion and a vertical portion. The first guide groove 121 is used to guide the bidirectional elastic telescopic frame 12, and the bending frame 3 is provided with a second guide groove 122 for guiding the pressure plate 6. A third tension spring 13 is fixedly connected between the bidirectional elastic telescopic frame 12 and the pressure plate 6. A pressure plate 14 is placed in the placement groove on the front side of the top of the bending frame 3. The telescopic portion of the bidirectional elastic telescopic frame 12 is squeezed and matched with the pressure plate 14. The pressure plate 14 is provided with a clamping groove 141 symmetrically distributed along the pressure plate 14, and the clamping groove 141 is used to clamp the telescopic portion of the bidirectional elastic telescopic frame 12.

[0036] During the process of the pressure plate 6 sliding upward along the bending frame 3, the pressure plate 6 first pulls the bidirectional elastic telescopic frame 12 to move upward synchronously through the third tension spring 13, so that the fixed part in the middle of the bidirectional elastic telescopic frame 12 slides upward along the slide groove 11, and the telescopic parts at the left and right ends of the bidirectional elastic telescopic frame 12 slide upward along the vertical parts of the left and right first guide grooves 121 respectively. Afterwards, when the telescopic part of the bidirectional elastic telescopic frame 12 slides upward to the turning point of the first guide groove 121, the bidirectional elastic telescopic frame 12 stops sliding upward, and the pressure plate 6 continues to slide upward along the bending frame 3, so that the third tension spring 13 is stretched until the bending of the entire coil is finally completed. At this time, the bottom of the pressure plate 6 just moves up to the height of the second guide groove 122, and the entire coil product will be pushed forward by the feeding assembly to the rear semicircle of the coil. The inner wall of the ring part fits with the cylindrical surface of the pressure plate 6, and the coil then drives the pressure plate 6 to slide forward along the second guide groove 122. The telescopic parts at the left and right ends of the two-way elastic telescopic frame 12 slide forward along the transverse parts of the two left and right first guide grooves 121 respectively until they are disengaged from the first guide groove 121 and correspond to the slot 141 on the same side. At this time, the telescopic part of the two-way elastic telescopic frame 12 in the compressed state is stuck in the slot 141 on the same side, and the third tension spring 13 is reset through the two-way elastic telescopic frame 12 to pull the pressure plate 14 upward to disengage from the placement groove of the bending frame 3, and clamp the bottom of the coil, and cooperate with the pressure plate 6 to achieve the effect of pressing the rear semicircular ring part of the coil up and down. In this way, the front semicircular ring part of the coil can be held by hand to take away the coil together with the pressure plate 6 and the pressure plate 14, so that the coil can be maintained in a shaped state after being removed.

[0037] like Figure 7 and Figure 8As shown, it also includes a guide frame 15, which is slidably connected to the pressure plate 14. When the pressure plate 6 moves forward, it contacts the rear end arc surface of the guide frame 15. The pressure plate 14 is slidably connected along the up and down directions with a slide rod 17 symmetrically distributed along the pressure plate 14. The bottom end of the slide rod 17 is fixedly connected to a baffle plate 16, which has two front and rear inclined grooves. The baffle plate 16 is squeezed and matched with the guide frame 15 through the inclined grooves.

[0038] When the pressure plate 6 slides forward along the second guide groove 122, its cylindrical surface will contact the guide frame 15 and squeeze the guide frame 15 to slide forward relative to the pressure plate 14. The guide frame 15 squeezes the baffle 16 upward through the inclined groove, thereby driving the slide rod 17 to slide upward along the pressure plate 14, achieving the effect of squeezing the rear semicircular ring part of the coil to the left and right. In this way, the coil can be further maintained in a shaped state after being removed.

[0039] Embodiment 3: Based on embodiment 2, Fig. 9 As shown, it also includes an arc-shaped push block 18, which is fixedly connected to the bending frame 3. The limit frame 4 is slidably connected to the slide 19 along the up and down directions. The slide 19 is fixedly connected to the top of the blocking frame 5. The front right side of the slide 19 is set as a wedge-shaped surface. When the arc-shaped push block 18 rotates one hundred and eighty degrees, the wedge-shaped surface squeezes the slide 19 to slide upward.

[0040] During the rotation process, the coil relies on itself to squeeze the inclined surface of the baffle 5, so that the baffle 5 moves upward intermittently, so that the coil can pass over the baffle 5. However, as the coil is stacked higher and higher, the force for squeezing the baffle 5 to slide upward also needs to be greater and greater, so it is more difficult to push the baffle 5 open. For this reason, it is necessary to assist in pushing the slide 19 to slide upward to prevent the coil from deforming. The specific auxiliary operation is as follows: when the bending frame 3 rotates, it drives the arc push block 18 to rotate, so that the arc push block 18 rotates to contact the slide 19, and squeezes the slide 19 to slide upward, thereby assisting the baffle 5 to slide upward. When the bending frame 3 reverses, it drives the arc push block 18 to rotate in the opposite direction, so that the arc push block 18 rotates to disengage from the slide 19. Under the action of gravity, the slide 19 and the baffle 5 slide downward synchronously.

[0041] Embodiment 4: Based on embodiment 3, Fig.10 As shown, it also includes a partition block 20, which is slidably connected to the bending frame 3, the partition block 20 contacts the cylindrical surface of the pressure plate 6, the height of the partition block 20 is equal to the height of the second guide groove 122, and a spring 21 is fixed between the partition block 20 and the bending frame 3.

[0042] When the coil drives the pressure plate 6 to slide forward along the second guide groove 122, since the pressure plate 6 and the magnet 7 are still affected by the magnetic attraction force, relying on pushing the coil to separate the pressure plate 6 and the magnet 7 may cause deformation of the coil, so it is necessary to assist the pressure plate 6 and the magnet 7 to separate. The specific auxiliary operation is as follows: initially, the cylindrical surface of the pressure plate 6 squeezes the partition block 20, and the spring 21 is in a compressed state. When the bottom of the pressure plate 6 just moves up to the height of the second guide groove 122, the spring 21 resets and drives the partition block 20 to move forward, thereby pushing the pressure plate 6 to move forward and separate from the magnet 7.

[0043] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
