Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of coil processing equipment, in particular to a coil bending and cutting device. BACKGROUND
[0002] An inductor coil is an electronic component wound by a wire, and is an important component in an inductor. In the preparation process of the coil, the free end of the wound coil to be processed needs to be bent and cut to form a first bending section and a second bending section of the coil.
[0003] In the prior art, when the coil to be processed is processed, the free end is first bent once, and then the free end is cut to reduce the excess length. Then, the free end is bent again to form a coil with a first bending section and a second bending section.
[0004] In this way, the preparation efficiency of the coil is low, and the pass rate of the prepared coil is low. CONTENT OF THE INVENTION
[0005] The present application provides a coil bending and cutting device for improving the preparation efficiency of the coil and improving the pass rate of the coil.
[0006] In order to achieve the above-mentioned purpose, the present application provides a coil bending and cutting device, which comprises a first bearing frame, a second bearing frame, a supporting mechanism, a first driving mechanism, a third bearing frame and a bending and cutting mechanism. The second bearing frame is arranged on the first bearing frame. The supporting mechanism is arranged on the second bearing frame, and is used for supporting the wound coil to be processed. The first driving mechanism is arranged on the first bearing frame, and the third bearing frame is arranged on the driving end of the first driving mechanism. The first driving mechanism is used for driving the third bearing frame to move in the vertical direction towards the direction close to and away from the supporting mechanism. The bending and cutting mechanism is arranged on the third bearing frame in a following manner, and cooperates with the supporting mechanism, and is used for bending and cutting the free end of the coil to be processed when the bending and cutting mechanism moves towards the supporting mechanism.
[0007] When the wound coil to be processed is placed on the supporting mechanism, the first driving mechanism can be controlled to drive the third bearing frame to move in the vertical direction towards the direction close to the supporting mechanism, and simultaneously drive the bending and cutting mechanism to move in the vertical direction towards the direction close to the supporting mechanism. Until the bending and cutting mechanism cooperates with the supporting mechanism to bend and cut the free end of the coil to be processed, the required coil is processed.
[0008] Therefore, when the coil to be processed is processed, the first driving mechanism is controlled to drive the third carrier frame to move in the vertical direction to the direction close to the supporting mechanism once, that is, the processing and forming of the coil to be processed can be completed. Compared with the prior art, the tool does not need to be replaced or the position of the coil to be processed needs to be changed, and the preparation efficiency of the coil can be improved.
[0009] In addition, the coil bending and cutting device provided by the embodiment of the present application can ensure that the length of the second bending section conforms to the preset length after the free end of the coil to be processed is bent and cut, and reduce the possibility that the qualified rate of the prepared coil is low.
[0010] In a possible implementation, the supporting mechanism includes a first forming die and a supporting column. The first forming die is arranged on the second carrier frame, and one end of the first forming die protrudes from the top surface of the second carrier frame. The supporting column is arranged on the first forming die, and the top end of the supporting column protrudes from the top surface of the first forming die. The coil to be processed is sleeved outside the supporting column, and the coil to be processed is supported on the top surface of the first forming die.
[0011] In a possible implementation, the bending and cutting mechanism includes a second forming die and a cutter. The second forming die is arranged on the third carrier frame close to one side of the second carrier frame in a follow-up manner. The side of the third carrier frame close to the second carrier frame is provided with an accommodating hole matched with the coil body of the coil to be processed. The second forming die is provided with a forming hole matched with the first forming die at a position corresponding to the accommodating hole. The cutter is arranged on the third carrier frame in a follow-up manner, and is used to cut the free end of the coil to be processed.
[0012] When the above technical solution is adopted, the coil to be processed that is wound is placed on the top surface of the first forming die, and the coil body is sleeved outside the supporting column.
[0013] At this time, the first driving mechanism can be controlled to drive the third carrier frame to move in the direction close to the supporting mechanism, that is, to drive the third carrier frame to move downward, and simultaneously drive the second forming die and the cutter to move in the vertical direction to the direction close to the supporting mechanism.
[0014] With the downward movement of the third carrier frame, the top end of the supporting column first extends into the forming hole, and then the coil body of the coil to be processed enters the forming hole. When the coil body and the supporting column enter the accommodating hole, the lower end of the second forming die contacts the region close to the coil body of the free end, the third carrier frame continues to move downward, the first forming die enters the forming hole, so that the lower end of the second forming die extrudes and bends the free end downward, and a bending angle is formed at the bending point position. The bending point is the position where the free end contacts the edge of the first forming die.
[0015] As the first forming mold enters the forming hole, the free end is squeezed to form a first bent section under the action of the outer wall of the first forming mold and the inner wall of the forming hole. The extension direction of the first bent section is the same as the movement direction of the second forming mold, that is, the first bent section extends downward.
[0016] When the free end contacts the top surface of the second support frame, it is bent again under the pressure between the bottom surface of the second forming mold and the top surface of the second support frame, forming the first second bent section. At the same time, the cutter contacts the first second bent section and cuts off the end of the first second bent section away from the second forming mold, removing the excess part and forming the second bent section. At this point, the coil processing and forming are completed.
[0017] In one possible implementation, a first groove is provided on the outer wall of the first forming mold to cooperate with the first bent section of the coil, and the extension direction of the first groove is parallel to the axial direction of the support column.
[0018] When the above technical solution is adopted, during the process of extruding the free end between the outer wall of the first forming mold and the inner wall of the forming hole to form the first bending segment, the area of the free end used to form the first bending segment is located in the first groove, which can improve the accuracy of the first bending segment, improve the processing quality of the coil, and ensure the qualification rate of the coil.
[0019] In one possible implementation, at the location corresponding to the first groove, the side of the second forming mold near the second support frame is provided with a second groove that cooperates with the second bent section of the coil. The extension direction of the second groove is perpendicular to the axial direction of the support column, and the second groove is connected to the forming hole.
[0020] When the above technical solution is adopted, during the process of forming the second bending section, the area of the free end used to form the second bending section is located in the second groove under the extrusion action between the bottom surface of the second forming mold and the top surface of the second bearing frame when the free end contacts the top surface of the second bearing frame. This can improve the accuracy of the second bending section, improve the processing quality of the coil, and ensure the qualification rate of the coil.
[0021] In one possible implementation, the support column is slidably disposed vertically on the first forming mold. The coil bending and cutting device also includes a first elastic element, the two ends of which elastically act on the second support frame and the support column, respectively, to apply a force to the support column close to the third support frame.
[0022] When adopting the above technical solution, the first elastic element can buffer the support column, preventing hard contact between the coil to be processed and the support column during placement, and avoiding damage to the inner coil of the coil body. This ensures coil quality and guarantees a high yield rate.
[0023] In one possible implementation, the second forming die is slidably mounted on the third support frame in a vertical direction. The coil bending and cutting device also includes a second elastic element, the two ends of which elastically act on the third support frame and the second forming die, respectively, to apply a force close to the second support frame to the second forming die.
[0024] When adopting the above technical solution, on the one hand, during the process of the second forming mold cooperating with the first forming mold to form the first bending section and the second bending section, the second elastic element can buffer the second forming mold to prevent the first forming mold, the second forming mold and the free end from hard contact, which would cause too much impact on the free end and reduce the processing accuracy and quality of the coil. At the same time, it ensures the service life of the first forming mold and the second forming mold.
[0025] On the other hand, after the lower end of the second forming mold contacts the top surface of the second support frame, the third support frame can continue to drive the cutter downwards, thus ensuring that the cutter completely cuts off the free end. Furthermore, it facilitates optimizing the relative positions of the cutter and the second forming mold, ensuring that the bending and cutting of the coil to be processed can be completed in a single downward movement of the third support frame.
[0026] In one possible implementation, the first molding die is movably mounted on the second support frame in the vertical direction.
[0027] When the above technical solution is adopted, the relative position of the first forming mold and the second support frame can be adjusted to adjust the size of the first forming mold protruding from the top surface of the second support frame, thereby making it easier to obtain the actual required size of the first bending section and expanding the applicability of the coil bending and cutting device provided in the embodiments of this application.
[0028] In one possible implementation, the coil bending and cutting device further includes a second driving mechanism disposed on the second support frame. A first forming mold is disposed at the driving end of the second driving mechanism, which drives the first forming mold to slide vertically relative to the second support frame.
[0029] When the above technical solution is adopted, after the bending and cutting mechanism and the support mechanism cooperate to complete the coil forming, the first drive mechanism drives the third support frame to move vertically away from the support mechanism, simultaneously driving the second forming mold and the cutter to move vertically away from the support mechanism, so that the second forming mold separates from the first forming mold. At this time, the formed coil is sleeved on the support column, and the coil is supported on the top surface of the first forming mold. In this case, the second drive mechanism can be controlled to drive the first forming mold to move upward relative to the support column and the second support frame to lift the coil, thereby facilitating the removal of the formed coil.
[0030] Furthermore, the extension and retraction distance of the drive end of the second drive mechanism can be controlled to control the size of the first forming mold protruding from the top surface of the second support frame, thereby achieving automated adjustment of the first forming mold and improving the overall automation of the coil bending and cutting device provided in this application embodiment.
[0031] In one possible implementation, the coil bending and cutting device further includes a third drive mechanism disposed on the first support frame. A second support frame is disposed at the drive end of the third drive mechanism, which drives the second support frame to rotate in the vertical direction.
[0032] When using the above technical solution, after the bending and cutting mechanism and the support mechanism cooperate to complete the coil forming, the coil is sleeved on the outside of the support column, and at the same time, the coil is supported on the top surface of the first forming mold. In this case, the second support frame can be rotated 180° vertically by controlling the third drive mechanism, so that the coil is located below the first forming mold. At this time, the first forming mold can be moved relative to the support column and the second support frame by controlling the second drive mechanism to push the coil, so that the coil detaches from the support column and can fall under its own gravity for easy collection.
[0033] In one possible implementation, the coil bending and cutting device further includes a fourth drive mechanism disposed on the first support frame. The first drive mechanism is disposed at the drive end of the fourth drive mechanism, and the fourth drive mechanism is used to drive the first drive mechanism to move horizontally toward and away from the support mechanism.
[0034] When the above technical solution is adopted, after the bending and cutting mechanism and the support mechanism work together to complete the coil processing and forming, the first driving mechanism can be driven by the fourth driving mechanism, which will simultaneously drive the third support frame and the bending and cutting mechanism to move away from the support mechanism, so as to avoid interference when the third driving mechanism drives the second support frame to rotate in the vertical direction.
[0035] Simultaneously, when the second drive mechanism drives the first forming mold to move relative to the support column and the second carrier frame to push the coil, causing the coil to detach from the support column and fall under its own gravity, the third drive mechanism can be controlled to drive the second carrier frame to continue rotating 180° in the vertical direction, causing the support mechanism to rotate from the release position to the forming position. In this case, it is convenient to place the coil to be processed on the support mechanism from directly above it. Attached Figure Description

[0054] In the description of this application, unless otherwise stated, "multiple" means two or more (including two), and similarly, "multiple groups" means two or more (including two groups).
[0055] First, it needs to be stated that, Figure 1 This is a schematic diagram of the completed coil 101 to be processed. Figure 2 This illustration shows the coil bending and cutting device provided in the embodiments of this application. Figure 1 The diagram shows the coil 102 after the coil 101 to be processed has been formed.
[0056] like Figure 1 As shown, the coil to be processed 101 has a coil body 1021 and two free ends. Figure 2As shown, the coil after processing includes a coil body 1021, a first bending section 1022, and a second bending section 1023.
[0057] In the prior art, in order to obtain Figure 2 The coil shown is typically processed by first bending the free end of the coil 101 to obtain a front bent section. At this point, the length of the front bent section is greater than the sum of the required lengths of the first bent section 1022 and the second bent section 1023. Then, the end of the front bent section furthest from the coil body 1021 is cut off to remove the excess length, resulting in a bent section. At this point, the length of the bent section is equal to the sum of the required lengths of the first bent section 1022 and the second bent section 1023. Finally, the bent section is bent to obtain the first bent section 1022 and the second bent section 1023, thus obtaining the desired result. Figure 2 The coil 102 shown.
[0058] In other words, in existing technologies, the process involves bending, cutting, and bending the free end to form the desired shape. Figure 2 The coil 102 shown.
[0059] In this situation, bending and cutting may require changing tools or the position of the coil 101 to be processed, resulting in low coil manufacturing efficiency. Furthermore, in existing technologies, a second bending is performed after removing the excess length. Since the required length of the second bending segment 1023 is often small, this increases the difficulty of bending. Simultaneously, there is a possibility that the length of the second bending segment 1023 may not match the preset length, leading to a low yield rate of the manufactured coil.
[0060] In view of the problems existing in the above-mentioned prior art, please refer to Figure 2 and Figure 3 As shown in the figure, this application provides a coil bending and cutting device, which includes a first support frame 1, a second support frame 2, a support mechanism 3, a first driving mechanism 4, a third support frame 5, and a bending and cutting mechanism 6.
[0061] In practice, the specific structures of the first support frame 1, the second support frame 2, and the third support frame 5 are not limited here, and shall be subject to the actual situation.
[0062] The second support frame 2 is disposed on the first support frame 1. The second support frame 2 can be fixedly installed on the first support frame 1 by means of welding, screw connection, riveting, etc., but in practice it is not limited to these methods.
[0063] The support mechanism 3 is set on the second support frame 2. The specific manner in which the support mechanism 3 is set on the second support frame 2 is not specified here.
[0064] Specifically, the support mechanism 3 is located at the top of the second support frame 2, and the support mechanism 3 is used to support the wound coil 101 to be processed. The coil 101 to be processed can be placed on the support mechanism 3 by its own weight.
[0065] The first drive mechanism 4 is disposed on the first support frame 1, and the third support frame 5 is disposed on the drive end of the first drive mechanism 4.
[0066] In specific implementation, the first drive mechanism 4 can be a linear module or a drive cylinder, etc. Of course, it is not limited to this. The specific implementation should be based on the ability to drive the third support frame 5 to make reciprocating linear motion in the vertical direction.
[0067] The mounting end of the first drive mechanism 4 can be fixedly installed on the first support frame 1 using screws. The third support frame 5 can be indirectly or directly fixedly installed on the drive end of the first drive mechanism 4. The first drive mechanism 4 is used to drive the third support frame 5 to move vertically towards and away from the support mechanism 3.
[0068] The bending and cutting mechanism 6 is movably mounted on the third support frame 5, and moves synchronously with the third support frame 5. When the third support frame 5 moves vertically toward and away from the support mechanism 3, the bending and cutting mechanism 6 moves synchronously with the third support frame 5 in the same direction.
[0069] The bending and cutting mechanism 6 works in conjunction with the support mechanism 3 to bend and cut the free end of the coil 101 to be processed when the bending and cutting mechanism 6 moves toward the support mechanism 3.
[0070] After the wound coil 101 is placed on the support mechanism 3, the first drive mechanism 4 can be controlled to drive the third support frame 5 to move vertically towards the support mechanism 3. In practice, the first drive mechanism 4 drives the third support frame 5 downwards, simultaneously driving the bending and cutting mechanism 6 to move vertically towards the support mechanism 3. This continues until the bending and cutting mechanism 6 cooperates with the support mechanism 3 to bend and cut the free end of the coil 101, resulting in... Figure 1 The coil 101 shown is processed into the shape shown. Figure 2 The coil 102 shown.
[0071] Thus, using the coil bending and cutting device provided in this embodiment, when processing the coil 101 to be processed, the first driving mechanism 4 can drive the third support frame 5, simultaneously moving the bending and cutting mechanism 6 vertically towards the support mechanism 3 once, thereby completing the processing and forming of the coil 101. Compared with the prior art, there is no need to change tools or the position of the coil 101 to be processed, which can improve the coil preparation efficiency.
[0072] Furthermore, by using the coil bending and cutting device provided in this application embodiment to bend and cut the free end of the coil 101 to be processed, it can be ensured that the length of the second bending segment 1023 matches the preset length, reducing the possibility of a low pass rate for the coil 102 after preparation.
[0073] After the bending and cutting mechanism 6 and the support mechanism 3 work together to complete the processing and forming of the coil 102, the first drive mechanism 4 can be controlled to drive the third support frame 5 to move in the vertical direction away from the support mechanism 3, and simultaneously drive the bending and cutting mechanism 6 to move in the vertical direction away from the support mechanism 3, so that the bending and cutting mechanism 6 is separated from the support mechanism 3. At this time, the processed coil 102 can be taken out.
[0074] In one possible implementation, combining Figure 3 and Figure 5 As shown, the support mechanism 3 includes a first forming mold 31 and a support column 32. The first forming mold 31 is disposed on the second support frame 2, and one end of the first forming mold 31 protrudes from the top surface of the second support frame 2. The support column 32 is disposed on the first forming mold 31, and the top end of the support column 32 protrudes from the top surface of the first forming mold 31. The coil to be processed 101 is sleeved on the support column 32, and the coil to be processed 101 is supported on the top surface of the first forming mold 31.
[0075] The cross-sectional shape of the support column 32 can match the shape of the inner ring of the coil body 1021, and the coil body 1021 is sleeved on the support column 32. The lower end of the coil body 1021 is in support contact with the top surface of the first forming mold 31, that is, the coil body 1021 is placed on the first forming mold 31.
[0076] The orthographic projection of the support column 32 on the second support frame 2 is located within the orthographic projection of the first forming mold 31 on the second support frame 2. At the same time, when the coil to be processed 101 is sleeved on the support column 32, the orthographic projection of the coil body 1021 on the second support frame 2 is located within the orthographic projection of the first forming mold 31 on the second support frame 2, so as to ensure the stability of the coil to be processed 101 placed on the support mechanism 3 and to ensure the processing accuracy of the coil 102.
[0077] Please combine Figure 4 andFigure 6 As shown, the bending and cutting mechanism 6 provided in this application embodiment includes a second forming mold 61 and a cutter 62. The second forming mold 61 is movably disposed on the side of the third support frame 5 near the second support frame 2, that is, the second forming mold 61 moves synchronously with the movement of the third support frame 5.
[0078] The third support frame 5 has a receiving hole 51 on the side near the second support frame 2, which mates with the coil body 1021 of the coil to be processed 101. Corresponding to the position of the receiving hole 51, the second forming mold 61 has a forming hole 611 that mates with the first forming mold 31, such as... Figure 6 As shown.
[0079] The cutter 62 is movably mounted on the third support frame 5. The cutter 62 moves synchronously with the movement of the third support frame 5. The cutter 62 is used to cut the free end of the coil 101 to be processed.
[0080] When using the above technical solution, in specific operation, the wound coil 101 to be processed is placed on the top surface of the first forming mold 31, and the coil body 1021 is sleeved on the support column 32.
[0081] For ease of description, the position where the free end contacts the edge of the first forming mold 31 is defined as the bending point.
[0082] At this time, the first drive mechanism 4 can be controlled to drive the third support frame 5 to move towards the support mechanism 3, that is, drive the third support frame 5 to move downward, and simultaneously drive the second forming mold 61 and the cutter 62 to move towards the support mechanism 3 in the vertical direction.
[0083] As the third support frame 5 moves downward, the top of the support column 32 first extends into the forming hole 611, and then the coil body 1021 of the coil to be processed 101 enters the forming hole 611. When the coil body 1021 and the support column 32 enter the receiving hole 51, after the lower end of the second forming mold 61 contacts the area of the free end near the coil body 1021, the third support frame 5 continues to move downward, and the first forming mold 31 enters the forming hole 611, so that the lower end of the second forming mold 61 presses down to bend the free end, and forms a bending angle at the bending point.
[0084] As the first forming mold 31 enters the forming hole 611, the free end is squeezed to form a first bending segment 1022 under the action of the outer wall of the first forming mold 31 and the inner wall of the forming hole 611. The extension direction of the first bending segment 1022 is the same as the movement direction of the second forming mold 61, that is, the first bending segment 1022 extends downward.
[0085] When the free end contacts the top surface of the second support frame 2, under the squeezing action between the bottom surface of the second forming mold 61 and the top surface of the second support frame 2, the free end is bent again to form the first second bent segment. At this time, the length of the first second bent segment is greater than the preset length of the second bent segment. The cutter 62 contacts the first second bent segment and cuts off the end of the first second bent segment away from the second forming mold 61, removing the excess part to form the second bent segment 1023. At this time, the processing and forming of the coil 102 is completed.
[0086] It should be noted that when using the coil bending and cutting device provided in this application embodiment to process coils, when placing the coil to be processed 101, the extension direction of the free end of the coil to be processed 101 is required to be perpendicular to the extension direction of the blade of the cutter 62.
[0087] In addition, it can be understood that the length of the first bending segment 1022 is equal to the dimension of the first forming mold 31 protruding from the top surface of the second support frame 2, that is, the distance between the top surface of the first forming mold 31 and the top surface of the second support frame 2 is equal to the length of the first bending segment 1022.
[0088] In addition, it should be noted that when the cutter 62 cuts the free end, the free end is placed on the top surface of the second support frame 2. This can be understood as the top surface of the second support frame 2 being the cutting support surface.
[0089] As an example, combined Figure 2 , Figure 5 and Figure 7 As shown, the outer wall of the first forming mold 31 is provided with a first groove 311 that cooperates with the first bending section 1022 of the coil 102. The extension direction of the first groove 311 is parallel to the axial direction of the support column 32.
[0090] Thus, during the process of extruding the free end between the outer wall of the first forming mold 31 and the inner wall of the forming hole 611 to form the first bending segment 1022, the area of the free end used to form the first bending segment 1022 is located within the first groove 311, which can improve the accuracy of the first bending segment 1022 and ensure the pass rate of the coil 102.
[0091] In specific implementation, the number of first grooves 311 is the same as the number of first bending segments 1022, and they correspond one-to-one. For example... Figure 7 As shown, there are two first grooves 311.
[0092] The vertical dimension of the first groove 311 can be equal to the length of the first bent segment 1022.
[0093] As another example, please combine Figure 2 , Figure 4 and Figure 6As shown, corresponding to the position of the first groove 311, the second forming mold 61 has a second groove 612 on the side near the second support frame 2, which mates with the second bent section 1023 of the coil 102. When the first forming mold 31 extends into the forming hole 611, the positions of the first groove 311 and the second groove 612 correspond. The extending direction of the second groove 612 is perpendicular to the axial direction of the support column 32, and the second groove 612 communicates with the forming hole 611.
[0094] Thus, during the process of forming the second bending segment 1023, the area of the free end used to form the second bending segment 1023 is located within the second groove 612, which can improve the accuracy of the second bending segment 1023, improve the processing quality of the coil 102, and ensure the pass rate of the coil 102.
[0095] In practice, the number of second grooves 612 is the same as the number of second bending segments 1023, and they correspond one-to-one. For example... Figure 6 As shown, there are two second grooves 612.
[0096] In some embodiments, the support column 32 is slidably disposed on the first forming mold 31 in a vertical direction. The coil bending and cutting device provided in this application embodiment further includes a first elastic member, the two ends of which elastically act on the second support frame 2 and the support column 32, respectively, for applying a force to the support column 32 close to the third support frame 5.
[0097] The first elastic element acts as a buffer for the support column 32. During the placement of the coil 101 to be processed, the first elastic element can convert some energy into elastic potential energy, preventing the coil 101 to be processed from making hard contact with the support column 32 and preventing the support column 32 from damaging the inner coil of the coil body 1021. In this way, the quality of the coil can be ensured and the pass rate of the coil can be guaranteed.
[0098] In practice, mounting holes can be made on the second support frame 2, and the first forming mold 31 can be placed inside the mounting holes. Simultaneously, an extension hole is provided on the first forming mold 31, and a support column 32 is placed inside the extension hole, and the support column 32 is slidably positioned within the extension hole. One end of the first elastic member is mounted on the second support frame 2, and the other end of the first elastic member can elastically act on the lower end of the support column 32.
[0099] In the embodiments provided in this application, the first elastic element can be a spring or an elastic sheet; no specific limitation is made here, and the actual situation shall prevail.
[0100] In other embodiments, the second forming mold 61 is slidably disposed on the third support frame 5 in a vertical direction. The coil bending and cutting device provided in this application embodiment also includes a second elastic member, the two ends of which elastically act on the third support frame 5 and the second forming mold 61, respectively, to apply a force close to the second support frame 2 to the second forming mold 61.
[0101] Thus, on the one hand, during the process of the second forming mold 61 cooperating with the first forming mold 31 to form the first bending section 1022 and the second bending section 1023, the second elastic element can buffer the second forming mold 61 to prevent the first forming mold 31, the second forming mold 61 and the free end from making hard contact, which would cause too much impact on the free end and reduce the processing accuracy and quality of the coil 102. At the same time, it ensures the service life of the first forming mold 31 and the second forming mold 61.
[0102] On the other hand, after the lower end of the second forming mold 61 contacts the top surface of the second support frame 2, the third support frame 5 can continue to drive the cutter 62 downward, thus ensuring that the cutter 62 completely cuts off the free end. In addition, it is convenient to optimize the relative position of the cutter 62 and the second forming mold 61, so as to ensure that the bending and cutting of the coil 101 to be processed can be completed in one downward movement of the third support frame 5.
[0103] In the embodiments provided in this application, the second elastic element can be a spring or an elastic sheet; no specific limitation is made here, and the actual situation shall prevail.
[0104] As a feasible approach, the first forming mold 31 is movably mounted on the second support frame 2 in the vertical direction.
[0105] As can be seen from the above, the length of the first bending segment 1022 is equal to the dimension of the first forming mold 31 protruding from the top surface of the second support frame 2.
[0106] Thus, by adjusting the relative position of the first forming mold 31 and the second support frame 2, the size of the first forming mold 31 protruding from the top surface of the second support frame 2 can be adjusted, thereby facilitating the obtaining of the actual required size of the first bending section 1022 and expanding the applicability of the coil bending and cutting device provided in this application embodiment.
[0107] In one possible implementation, such as Figure 3 and Figure 4 As shown, the coil bending and cutting device provided in this application embodiment also includes a second driving mechanism 7, which is disposed on the second support frame 2.
[0108] The first molding die 31 is disposed at the driving end of the second driving mechanism 7, which is used to drive the first molding die 31 to slide relative to the second support frame 2 in the vertical direction.
[0109] The mounting end of the second drive mechanism 7 can be fixedly mounted on the second support frame 2 using a screw connection. The first molding die 31 can be indirectly or directly fixedly mounted on the drive end of the second drive mechanism 7. The second drive mechanism 7 is used to drive the first molding die 31 to slide vertically relative to the second support frame 2.
[0110] In this case, after the bending and cutting mechanism 6 and the support mechanism 3 cooperate to complete the forming of the coil 102, the first drive mechanism 4 drives the third support frame 5 to move vertically away from the support mechanism 3, simultaneously driving the second forming mold 61 and the cutter 62 to move vertically away from the support mechanism 3, so that the second forming mold 61 disengages from the first forming mold 31. At this time, the formed coil 102 is sleeved on the support column 32, and the coil 102 is supported on the top surface of the first forming mold 31. In this case, the second drive mechanism 7 can be controlled to drive the first forming mold 31 to move upward relative to the support column 32 and the second support frame 2 to lift the coil 102, thereby facilitating the removal of the formed coil 102.
[0111] Furthermore, the size of the first forming mold 31 protruding from the top surface of the second support frame 2 can be controlled by controlling the extension and retraction distance of the drive end of the second drive mechanism 7, thereby realizing the automated adjustment of the first forming mold 31 and improving the overall automation level of the coil bending and cutting device provided in this application embodiment.
[0112] In specific implementation, the second drive mechanism 7 can be a linear module or a drive cylinder, etc. Of course, it is not limited to this. The specific implementation should be based on the ability to drive the first forming mold 31 to make reciprocating linear motion in the vertical direction.
[0113] In some embodiments, such as Figure 3 and Figure 4 As shown, the coil bending and cutting device provided in this embodiment of the application further includes a third driving mechanism 8, which is disposed on the first support frame 1. The second support frame 2 is disposed on the driving end of the third driving mechanism 8, and the third driving mechanism 8 is used to drive the second support frame 2 to rotate in the vertical direction.
[0114] The mounting end of the third drive mechanism 8 can be fixedly installed on the first support frame 1 using a screw connection. The second support frame 2 can be indirectly or directly fixedly installed on the drive end of the third drive mechanism 8.
[0115] The third drive mechanism 8 is used to drive the second support frame 2 to rotate in the vertical direction. Since the second support frame 2 is located at the drive end of the third drive mechanism 8, and the support mechanism 3 is located on the second support frame 2, when the third drive mechanism 8 drives the second support frame 2 to rotate in the vertical direction, it can simultaneously drive the support mechanism 3 to rotate in the vertical direction.
[0116] Thus, after the bending and cutting mechanism 6 and the support mechanism 3 cooperate to complete the forming of the coil 102, the coil 102 is sleeved on the support column 32, and simultaneously supported on the top surface of the first forming mold 31. In this case, the third drive mechanism 8 can be controlled to drive the second support frame 2, simultaneously driving the first forming mold 31 and the support column 32 to rotate 180° vertically, so that the support mechanism 3 rotates from the forming position to the release position, and the coil 102 is located below the first forming mold 31. At this time, the second drive mechanism 7 can be controlled to drive the first forming mold 31 to move relative to the support column 32 and the second support frame 2, so as to push the coil 102, causing the coil 102 to detach from the support column 32, and the coil 102 can fall under its own gravity for easy collection.
[0117] In one alternative approach, such as Figure 3 and Figure 4 As shown, the coil bending and cutting device provided in this embodiment of the application further includes a fourth driving mechanism 9, which is disposed on the first support frame 1. The first driving mechanism 4 is disposed at the driving end of the fourth driving mechanism 9, and the fourth driving mechanism 9 is used to drive the first driving mechanism 4 to move in the horizontal direction toward and away from the support mechanism 3.
[0118] In practice, the mounting end of the fourth drive mechanism 9 can be fixedly installed on the first support frame 1 using a screw connection. The first drive mechanism 4 can be indirectly or directly fixedly installed on the drive end of the fourth drive mechanism 9.
[0119] Since the third support frame 5 is located at the drive end of the first drive mechanism 4, and the bending and cutting mechanism 6 is movably located on the third support frame 5, when the fourth drive mechanism 9 drives the first drive mechanism 4 to move horizontally toward and away from the support mechanism 3, it can simultaneously drive the bending and cutting mechanism 6 to move horizontally toward and away from the support mechanism 3.
[0120] Thus, after the bending and cutting mechanism 6 and the support mechanism 3 work together to complete the processing and forming of the coil 102, the first drive mechanism 4 can be driven by the fourth drive mechanism 9, which in turn drives the third support frame 5 and the bending and cutting mechanism 6 to move away from the support mechanism 3, so as to avoid interference when the third drive mechanism 8 drives the second support frame 2 to rotate in the vertical direction.
[0121] Simultaneously, when the second drive mechanism 7 drives the first forming mold 31 to move relative to the support column 32 and the second carrier frame 2, pushing the coil 102, causing the coil 102 to detach from the support column 32, and after the coil 102 falls under its own gravity, the third drive mechanism 8 can be controlled to drive the second carrier frame 2 to continue rotating 180° in the vertical direction, causing the support mechanism 3 to rotate from the release position to the forming position. In this case, it is convenient to place the coil 101 to be processed on the support mechanism 3 from directly above the support mechanism 3.
[0122] Subsequently, the first drive mechanism 4 can be driven by the fourth drive mechanism 9, which in turn drives the third support frame 5 and the bending and cutting mechanism 6 to move closer to the support mechanism 3, so that the support mechanism 3 and the bending and cutting mechanism 6 cooperate to perform the bending and cutting work of the coil 101 to be processed.
