[0014] A method for double-action bending and forming of wire, using the injection molding product production equipment described above, comprises the following steps:

[0015] S1. The staff places the wire inside the housing and feeds the wire through the wire feeding mechanism installed inside the housing. The wire material is continuously fed out of the housing through the rotating hole and along the center hole of the rotating column.

[0016] S2. The drive motor in the drive unit starts, and the drive motor drives the corresponding cam to start rotating. On one hand, the convex part of the cam squeezes one end of the corresponding push rod, and on the other hand, the other end of the push rod pushes the corresponding fixed block and slider on the guide rail and moves them towards the feeding part. During this process, the slider drives the pneumatic spring rod to be stretched, and the pneumatic spring rod is in a stretched state. Conversely, if the other end of the push rod cancels the push of the corresponding fixed block and slider on the guide rail, due to the characteristics of the pneumatic spring rod itself, the pneumatic spring rod will pull the corresponding slider back and away from the feeding part, and the pneumatic spring rod is in a compressed state.

[0017] S3. After the driving component corresponding to the positioning component is started through step S2, the two corresponding positioning vertical bars drive the positioning horizontal bar and positioning ear plate to move closer to each other. The two positioning ear plates drive the two positioning bars to fit together and form a conveying channel through the two positioning grooves, so that the two positioning bars clamp and assist in positioning the wire material. The wire material continues to be conveyed through the conveying channel formed by the two positioning grooves.

[0018] S4. Simultaneously, after the driving components corresponding to the coiling component and the limiting component are activated through step S2, on the one hand, the moving bar drives the coiling motor, the first clamp, and the column to move towards the feeding component, and on the other hand, the limiting vertical bar drives the limiting horizontal bar, the limiting ear plate, the vertical rod, the second clamp, and the heat dissipation component to move towards the feeding component synchronously until the first clamp and the second clamp are in contact with each other. The wire material continues to be conveyed through the middle position of the first clamp and the second clamp. During this process, the micro cylinder in the heat dissipation component is activated. The output end of the micro cylinder moves the lifting block, the extrusion plate, and the sponge block towards the wire material until the two sponge blocks clamp and adhere the two sides of the wire material. Then, the micro oil pump extracts the oil from the micro oil storage box through the oil extraction pipe and conveys it to the sponge block through the conveying pipe to wet the sponge block, so that the sponge block lubricates and cools the wire material.

[0019] S5. If the wire material has different thicknesses or needs to be flipped, the wire material can push the sponge blocks and extrusion plates on both sides in opposite directions, so that the slide bar slides in the guide groove. At this time, the micro spring is in a compressed state, thus adapting to wire materials of different thicknesses.

[0020] S6. Subsequently, the winding motor drives the column to rotate, and the wire material located between the first clamp and the second clamp is bent. By controlling the rotation angle of the winding motor, the bending angle of the wire material can be controlled over a wide range.

[0021] S7. If it is necessary to bend the wire material in a small range, the wire material should first be kept in the middle of the second clamp for conveying. The column stops rotating and then starts through the drive corresponding to the bending part. The bending vertical strip, bending horizontal strip, bending ear plate and bending strip in the bending part move as a whole. The arc surface on the bending strip approaches the wire material and squeezes the wire material as required. During the continuous conveying process, the arc surface continuously applies pressure and the wire material forms a small range of bending angle.

[0022] S8. Finally, through the feeding of the feeding component and the large-range bending and rotation of the coiling component, combined with the small-range bending of the bending component, the wire material is bent into the required shape. Then, the corresponding drive component and guide component of the breaking component are activated, and the cutting edges of the two breaking tools approach each other, cutting off and separating the formed wire material workpiece from the unformed wire material.

[0023] The advantages of this invention are:

[0024] 1. The main component provides a support platform for the drive component and the execution component, concentrating the drive component and the execution component on the same plane, so that the wire raw material can be bent and formed on the same plane.

[0025] 2. The drive component provides a power source for the actuator, enabling the actuator to move along a specified track. The actuator then bends the unbent wire material into the required shape. During bending, it lubricates and dissipates heat from the wire material, preventing excessive heat and friction from repeated bending in close proximity, thereby improving the wire's service life.

[0026] 3. The winding motor drives the column to rotate, and the wire material located between the first clamp and the second clamp is bent. By controlling the rotation angle of the winding motor, the bending angle of the wire material can be controlled over a wide range.

[0027] 4. As the wire material continues to be conveyed through the middle position of the first and second clamps, the miniature cylinder in the heat sink is activated. The output end of the miniature cylinder moves the lifting block, extrusion plate, and sponge block toward the wire material until the two sponge blocks clamp and adhere the two sides of the wire material. Immediately afterwards, the miniature oil pump draws oil from the miniature oil storage box through the oil extraction pipe and delivers it to the sponge block through the delivery pipe, wetting the sponge block. This allows the sponge block to lubricate and cool the wire material, reducing the probability of the wire's service life being reduced due to repeated bending at close range, which generates a large amount of heat and friction. This improves the service life of the wire and saves costs.

[0028] 5. If the wire material has different thicknesses or needs to be flipped, the wire material can push the sponge blocks and extrusion plates on both sides in opposite directions, so that the slide bar slides in the guide groove. At this time, the micro spring is in a compressed state, thus adapting to wire materials of different thicknesses. Attached Figure Description

Detailed Implementation

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0044] Example 1

[0045] Please see Figure 1-12The present invention provides the following technical solution: a wire double-action bending forming mold, comprising a main body component 100, a drive component 200, and an execution component 300; wherein, the main body component 100 provides a support platform for the drive component 200 and the execution component 300, concentrating the drive component 200 and the execution component 300 on the same plane, so that the wire raw material can be bent and formed on the same plane; the drive component 200 provides a power source for the execution component 300, so that the execution component 300 can move according to a specified track, while the execution component 300 bends the unbent wire raw material into the required shape, and lubricates and dissipates heat from the wire raw material during bending, avoiding the generation of large heat and friction when the wire is repeatedly bent in a close place, thereby improving the service life of the wire.

[0046] Specifically, the main component 100 includes a mounting base 101, a housing 102 disposed on one side of the mounting base 101, and a working panel 103 disposed at one end of the housing 102; wherein, a wire feeding mechanism is installed inside the housing 102, and when the wire feeding mechanism transports wires, the housing 102 can also be used to support and bear the wire feeding mechanism.

[0047] Specifically, the drive assembly 200 is evenly arranged in the circumferential direction on the side wall of the working panel 103 away from the housing 102, including a drive member 201 and a guide member 202 disposed on one side of the drive member 201; wherein, the drive member 201 is used to generate a power source and drive the guide member 202 to move, and the guide member 202 is used to move according to a specified angle and orientation to avoid misalignment with the wire material.

[0048] Specifically, the execution component 300 includes a feeding component 301, a curling component 302 vertically disposed at one end of the feeding component 301, a limiting component 303 disposed at the end of the feeding component 301 away from the curling component 302, a bending component 304 horizontally disposed at one end of the feeding component 301, a breaking component 305 diagonally symmetrically disposed at both ends of the feeding component 301, and a positioning component 306 intersecting with the breaking component 305. The curling component 302, the limiting component 303, the bending component 304, the breaking component 305 and the positioning component 306 are all located on the corresponding guide component 202.

[0049] The unbent wire material is fed through the wire feeding mechanism inside the housing 102 and transported to the working panel 103 via the feeding component 301. The positioning component 306 is used to clamp and assist in positioning the wire material. The coiling component 302 and the limiting component 303 are used to clamp and limit the wire material and perform large-angle bending. The bending component 304 is used to perform small-angle bending of the wire material. Finally, the breaking component 305 is used to cut off and separate the formed wire workpiece from the unformed wire material.

[0050] Furthermore, the drive component 201 includes a drive motor 2011, a cam 2012 disposed at the output end of the drive motor 2011, a rotating shaft 2013 disposed on one side of the drive motor 2011, and a push rod 2014 sleeved on the rotating shaft 2013. The side of the drive motor 2011 away from the cam 2012 is connected to the side wall of the working panel 103 away from the housing 102, and one end of the push rod 2014 is located within the rotation radius of the cam 2012.

[0051] The driving component 201 includes a driving motor 2011, multiple cams 2012, multiple rotating shafts 2013, and multiple push rods 2014. Each component consists of a driving motor 2011, a cam 2012, a rotating shaft 2013, and a push rod 2014. The driving motor 2011 drives the cam 2012 to rotate synchronously. When the protruding part of the cam 2012 moves to one end of the push rod 2014, the push rod 2014 is squeezed and rotates axially along the rotating shaft 2013. The other end of the push rod 2014 extends above the corresponding guide rail 2021 and is in contact with one end of the corresponding slider 2024. When the push rod 2014 rotates, its other end pushes the slider 2024 to slide on the guide rail 2021.

[0052] Furthermore, the guide component 202 includes a guide rail 2021, a pneumatic spring rod 2022 disposed at one end of the guide rail 2021, a connecting block 2023 disposed at the end of the pneumatic spring rod 2022 away from the guide rail 2021, a slider 2024 disposed on the guide rail 2021, and a fixing block 2025 disposed on the side of the slider 2024 away from the guide rail 2021; one side of the guide rail 2021 can be connected to the side wall of the working panel 103 away from the housing 102, and a groove 2026 is provided on the side of the guide rail 2021 away from the working panel 103, through which the slider 2024 can be slidably connected to the guide rail 2021; the end of the pneumatic spring rod 2022 away from the connecting block 2023 can pass through the side wall of the guide rail 2021 and be connected to the slider 2024 through the groove 2026; and the end of the push rod 2014 away from the cam 2012 is located at one end of the fixing block 2025.

[0053] The other end of the push rod 2014 pushes the corresponding fixed block 2025 and slider 2024 on the guide rail 2021 and moves them toward the feeding component 301. During this process, the slider 2024 drives the pneumatic spring rod 2022 to be stretched, and the pneumatic spring rod 2022 is in a stretched state. Conversely, if the other end of the push rod 2014 cancels the push of the corresponding fixed block 2025 and slider 2024 on the guide rail 2021, due to the characteristics of the pneumatic spring rod 2022 itself, the pneumatic spring rod 2022 will pull the corresponding slider 2024 back and away from the feeding component 301, and the pneumatic spring rod 2022 will be in a compressed state.

[0054] Furthermore, the feeding component 301 includes a rotating disk 3011, a rotating column 3012 disposed on one side of the rotating disk 3011, and a rotating head 3013 disposed on the end of the rotating column 3012 away from the rotating disk 3011; the side of the rotating disk 3011 away from the rotating column 3012 is connected to the side wall of the working panel 103 away from the housing 102, a rotating hole 3014 is provided in the middle of the side wall of the working panel 103, and a through hole 3015 is provided on the side wall of the rotating disk 3011. The rotating column 3012 is aligned with the rotating hole 3014. The end of the rotating column 3012 away from the rotating head 3013 can be connected to the rotating disk 3011 through the through hole 3015. One end of the rotating column 3012 is provided with an insertion hole 3016. The end of the rotating head 3013 near the rotating column 3012 can pass through the rotating column 3012 through the insertion hole 3016 and extend into the housing 102 through the rotating hole 3014. The end of the rotating head 3013 away from the rotating column 3012 is used for wire conveying.

[0055] The rotating disk 3011 is used to mount the feeding component 301 as a whole on the working panel 103. The wire material passes through the rotating disk 3011 through the rotating hole 3014 and the through hole 3015, and is then conveyed to the working panel 103 through the rotating column 3012 and the rotating head 3013. The rotating column 3012 is used to guide the wire material being fed out, so that the wire material is coaxial with the rotating head 3013 when it is fed out.

[0056] Furthermore, the coiling component 302 includes a moving bar 3021, a first clamp 3022 disposed at one end of the moving bar 3021, a coiling motor 3023 sleeved on the moving bar 3021, and a column 3024 eccentrically disposed at the output end of the coiling motor 3023. One side of the moving bar 3021 is connected to the side of the corresponding slider 2024 away from the guide rail 2021, and the end of the first clamp 3022 away from the moving bar 3021 can extend to the output end of the coiling motor 3023.

[0057] The limiting component 303 includes a limiting vertical bar 3031, a limiting horizontal bar 3032 sleeved on the limiting vertical bar 3031, a limiting ear plate 3033 disposed at the end of the limiting horizontal bar 3032 away from the limiting vertical bar 3031, a vertical rod 3034 disposed at the end of the limiting ear plate 3033 away from the limiting horizontal bar 3032, and a second clamp 3035 disposed at the end of the vertical rod 3034 away from the limiting ear plate 3033. The end of the limiting vertical bar 3031 away from the limiting horizontal bar 3032 is connected to the side of the corresponding slider 2024 away from the guide rail 2021. The second clamp 3035 is located directly below the first clamp 3022.

[0058] In this process, after the drive unit 201 corresponding to the coiling part 302 and the limiting part 303 is started in step S2, on the one hand, the moving bar 3021 drives the coiling motor 3023, the first clamp 3022 and the column 3024 to move towards the feeding part 301. On the other hand, the limiting bar 3031 drives the limiting horizontal bar 3032, the limiting ear plate 3033, the vertical rod 3034, the second clamp 3035 and the heat sink 307 to move towards the feeding part 301 simultaneously until the first clamp 3022 and the second clamp 3035 are in contact with each other. The wire material continues to be conveyed through the middle position of the first clamp 3022 and the second clamp 3035. Through the cooperation of the coiling part 302 and the limiting part 303, the wire material is limited, avoiding the poor stability caused by the swaying of the wire material during bending, thereby improving the stability of the wire material during bending, and thus improving the bending efficiency of the bending forming equipment and saving costs.

[0059] The coiling motor 3023 drives the column 3024 to rotate, and the wire material located between the first clamp 3022 and the second clamp 3035 is bent. By controlling the rotation angle of the coiling motor 3023, the bending angle of the wire material can be controlled over a wide range.

[0060] Furthermore, a heat sink 307 is provided on one side of the vertical rod 3034. The heat sink 307 includes a miniature cylinder 3071, a lifting block 3072 disposed at the output end of the miniature cylinder 3071, a pressing plate 3073 disposed on the lifting block 3072, and a sponge block 3074 disposed on one side of the pressing plate 3073. The pressing plate 3073 and the sponge block 3074 are symmetrically distributed about both sides of the wire.

[0061] As the wire material continues to be conveyed through the middle position of the first clamp 3022 and the second clamp 3035, the miniature cylinder 3071 in the heat sink 307 is activated. The output end of the miniature cylinder 3071 moves the lifting block 3072, the extrusion plate 3073, and the sponge block 3074 toward the wire material until the two sponge blocks 3074 clamp and adhere the two sides of the wire material. Immediately afterwards, the miniature oil pump 3075-2 draws oil from the miniature oil storage box 3075-1 through the oil extraction pipe 3075-3 and delivers it to the sponge block 3074 through the delivery pipe, wetting the sponge block 3074. This allows the sponge block 3074 to lubricate and cool the wire material, reducing the probability of the wire being repeatedly bent in close proximity, generating large amounts of heat and friction, which would reduce the lifespan of the wire. This improves the lifespan of the wire and saves costs.

[0062] The top of the lifting block 3072 is provided with a guide groove 3072-1, which is symmetrically distributed about both ends of the wire. Inside the guide groove 3072-1, there are symmetrically arranged sliders 3072-2 about both sides of the wire. The side of the slider 3072-2 away from the guide groove 3072-1 can be connected to one end of the extrusion plate 3073. A miniature spring 3072-3 is provided at one end of the slider 3072-2, and the end of the miniature spring 3072-3 away from the slider 3072-2 is connected to the inner wall of the guide groove 3072-1.

[0063] If the wire material has different thicknesses or needs to be flipped, the wire material can push the sponge blocks 3074 and the extrusion plate 3073 on both sides in opposite directions, so that the slide bar 3072-2 slides in the guide groove 3072-1. At this time, the micro spring 3072-3 is in a compressed state, thus adapting to wire materials of different thicknesses.

[0064] The lifting block 3072 has a cavity 3075 inside, and a miniature oil storage box 3075-1 is installed inside the cavity 3075. A miniature oil pump 3075-2 is installed on the top of the miniature oil storage box 3075-1. An oil suction pipe 3075-3 is installed at one end of the miniature oil pump 3075-2. The end of the oil suction pipe 3075-3 away from the miniature oil pump 3075-2 can be connected to the miniature oil storage box 3075-1. An output pipe 3075-4 is installed at the end of the miniature oil pump 3075-2 away from the oil suction pipe 3075-3. A conveying hole 3072-4 is symmetrically opened in the middle of the two guide grooves 3072-1. The conveying holes 3072-4 are symmetrically distributed on both sides of the wire. The output pipe 3075-4 can be connected to one end of the sponge block 3074 through the conveying hole 3072-4.

[0065] Among them, the miniature oil storage box 3075-1 and the miniature oil pump 3075-2 are replaceable and detachable. The output pipe 3075-4 is used to deliver oil through the delivery hole 3072-4 to the sponge block 3074, so that the sponge block 3074 is wetted, thereby allowing the sponge block 3074 to lubricate and cool the wire material.

[0066] Furthermore, the bending component 304 includes a bending vertical strip 3041, a bending horizontal strip 3042 sleeved on the bending vertical strip 3041, a bending ear plate 3043 disposed at the end of the bending horizontal strip 3042 away from the bending vertical strip 3041, and a bending strip 3044 disposed at the end of the bending ear plate 3043 away from the bending horizontal strip 3042. The end of the bending vertical strip 3041 away from the bending horizontal strip 3042 is connected to the side of the corresponding slider 2024 away from the guide rail 2021. The end of the bending strip 3044 away from the bending ear plate 3043 is provided with an arc-shaped surface 3045.

[0067] If a small-range bending of the wire material is required, the wire material is first kept in the middle of the second clamp 3035 for conveying. The column 3024 stops rotating. Then, the drive component 201 corresponding to the bending component 304 is started. The bending vertical bar 3041, bending horizontal bar 3042, bending ear plate 3043 and bending bar 3044 in the bending component 304 move as a whole. The arc surface 3045 on the bending bar 3044 moves closer to the wire material and squeezes the wire material as needed. During the continuous conveying process, the arc surface 3045 continuously applies pressure, and the wire material forms a small-range bending angle.

[0068] Furthermore, the breaking component 305 includes a breaking vertical strip 3051, a breaking horizontal strip 3052 sleeved on the breaking vertical strip 3051, a breaking ear plate 3053 disposed at the end of the breaking horizontal strip 3052 away from the breaking vertical strip 3051, and a breaking cutter 3054 disposed at the end of the breaking ear plate 3053 away from the breaking horizontal strip 3052. The end of the breaking vertical strip 3051 away from the breaking horizontal strip 3052 is connected to the side of the corresponding slider 2024 away from the guide rail 2021. The end of the breaking cutter 3054 away from the breaking ear plate 3053 has a cutting end 3055.

[0069] The wire material is bent into the required shape by the feeding component 301 and the large-range bending and rotation of the coiling component 302, combined with the small-range bending of the bending component 304. Then, the driving component 201 and the guide component 202 corresponding to the breaking component 305 are activated, and the cutting edges 3055 of the two breaking tools 3054 approach each other to cut off and separate the formed wire material workpiece from the unformed wire material.

[0070] Furthermore, the positioning component 306 includes a positioning vertical strip 3061, a positioning horizontal strip 3062 sleeved on the positioning vertical strip 3061, a positioning ear plate 3063 disposed at the end of the positioning horizontal strip 3062 away from the positioning vertical strip 3061, and a positioning strip 3064 disposed at the end of the positioning ear plate 3063 away from the positioning horizontal strip 3062. The end of the positioning vertical strip 3061 away from the positioning horizontal strip 3062 is connected to the side of the corresponding slider 2024 away from the guide rail 2021. The end of the positioning strip 3064 away from the positioning ear plate 3063 has a positioning groove 3065.

[0071] When the driving component 201 corresponding to the positioning component 306 is activated in step S2, the two corresponding positioning vertical bars 3061 drive the positioning horizontal bar 3062 and the positioning ear plate 3063 to move closer to each other. The two positioning ear plates 3063 drive the two positioning bars 3064 to fit together and form a conveying channel through the two positioning grooves 3065, so that the two positioning bars 3064 clamp and assist in positioning the wire material. The wire material continues to be conveyed through the conveying channel formed by the two positioning grooves 3065.

[0072] Example 2

[0073] Please see Figure 1-12 The operation of the above-mentioned device is explained as follows:

[0074] Step 1: The staff places the wire inside the housing 102 and feeds the wire through the wire feeding mechanism installed inside the housing 102. The wire material is continuously fed out from the housing 102 through the rotating hole 3014 and along the center hole of the rotating column 3012.

[0075] Step 2: The drive motor 2011 in the drive unit 201 starts, and the drive motor 2011 drives the corresponding cam 2012 to start rotating. On the one hand, the protruding part of the cam 2012 squeezes one end of the corresponding push rod 2014. On the other hand, the other end of the push rod 2014 pushes the corresponding fixed block 2025 and slider 2024 on the guide rail 2021 and moves them toward the feeding unit 301. During this process, the slider 2024 drives the pneumatic spring rod 2022 to be stretched. The pneumatic spring rod 2022 is in a stretched state. Conversely, if the other end of the push rod 2014 cancels the push of the corresponding fixed block 2025 and slider 2024 on the guide rail 2021, due to the characteristics of the pneumatic spring rod 2022 itself, the pneumatic spring rod 2022 will pull the corresponding slider 2024 back and away from the feeding unit 301. The pneumatic spring rod 2022 is in a compressed state.

[0076] Step 3: After the driving component 201 corresponding to the positioning component 306 is started through step S2, the two corresponding positioning vertical bars 3061 drive the positioning horizontal bar 3062 and the positioning ear plate 3063 to move closer to each other. The two positioning ear plates 3063 drive the two positioning bars 3064 to fit together and form a conveying channel through the two positioning grooves 3065, so that the two positioning bars 3064 clamp and assist in positioning the wire material. The wire material continues to be conveyed through the conveying channel formed by the two positioning grooves 3065.

[0077] Step 4: Simultaneously, after the drive unit 201 corresponding to the coiling component 302 and the limiting component 303 is activated through step S2, on the one hand, the moving bar 3021 drives the coiling motor 3023, the first clamp 3022, and the column 3024 to move towards the feeding component 301; on the other hand, the limiting vertical bar 3031 drives the limiting horizontal bar 3032, the limiting ear plate 3033, the vertical rod 3034, the second clamp 3035, and the heat sink 307 to move towards the feeding component 301 simultaneously until the first clamp 3022 and the second clamp 3035 are in contact with each other, and the wire material passes through the first clamp 3022 and the second clamp. The conveying continues at the middle position of 3035. During this process, the miniature cylinder 3071 in the heat sink 307 is activated. The output end of the miniature cylinder 3071 moves the lifting block 3072, the extrusion plate 3073 and the sponge block 3074 toward the wire material until the two sponge blocks 3074 clamp and adhere the two sides of the wire material. Then, the miniature oil pump 3075-2 draws the oil from the miniature oil storage box 3075-1 through the oil extraction pipe 3075-3 and delivers it to the sponge block 3074 through the conveying pipe, wetting the sponge block 3074 so that the sponge block 3074 lubricates and cools the wire material.

[0078] Step 5: If the wire material has different thicknesses or needs to be flipped, the wire material can push the sponge blocks 3074 and the extrusion plate 3073 on both sides in opposite directions, so that the slide bar 3072-2 slides in the guide groove 3072-1. At this time, the micro spring 3072-3 is in a compressed state, thus adapting to wire materials of different thicknesses.

[0079] Step 6: Subsequently, the winding motor 3023 drives the column 3024 to rotate, and the wire material located between the first clamp 3022 and the second clamp 3035 is bent. By controlling the rotation angle of the winding motor 3023, the bending angle of the wire material can be controlled over a wide range.

[0080] Step 7: If a small-range bending of the wire material is required, the wire material should first be kept in the middle of the second clamp 3035 for conveying. The column 3024 stops rotating. Then, the drive component 201 corresponding to the bending component 304 is started. The bending vertical bar 3041, bending horizontal bar 3042, bending ear plate 3043 and bending bar 3044 in the bending component 304 move as a whole. The arc surface 3045 on the bending bar 3044 moves closer to the wire material and squeezes the wire material as needed. During the continuous conveying process, the arc surface 3045 continuously applies pressure, and the wire material forms a small-range bending angle.

[0081] Step 8: Finally, the wire material is bent into the required shape by the feeding component 301 and the large-range bending and rotation of the coiling component 302, combined with the small-range bending of the bending component 304. Then, the driving component 201 and the guide component 202 corresponding to the breaking component 305 are activated, and the cutting edges 3055 of the two breaking tools 3054 approach each other to cut off and separate the formed wire material workpiece from the unformed wire material.

[0082] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

5. A method for forming wire by double-action bending, characterized in that: Using any one of the wire double-action bending forming dies described in claims 1-4, the following steps are performed: S1. The staff places the wire inside the housing (102) and feeds the wire through the wire feeding mechanism installed inside the housing (102). The wire material is continuously fed out from the housing (102) through the rotating hole (3014) and along the center hole of the rotating column (3012). S2. The drive motor (2011) in the drive unit (201) starts, and the drive motor (2011) drives the corresponding cam (2012) to start rotating. On the one hand, the protruding part of the cam (2012) squeezes one end of the corresponding push rod (2014), and on the other hand, the other end of the push rod (2014) pushes the corresponding fixed block (2025) and slider (2024) on the guide rail (2021) and moves them toward the feeder (301). During this process, the slider... (2024) drives the pneumatic spring rod (2022) to stretch, and the pneumatic spring rod (2022) is in a stretched state. Conversely, if the other end of the push rod (2014) cancels the push of the corresponding fixed block (2025) and slider (2024) on the guide rail (2021), due to the characteristics of the pneumatic spring rod (2022), the pneumatic spring rod (2022) will pull the corresponding slider (2024) back and away from the feeder (301), and the pneumatic spring rod (2022) will be in a compressed state. S3. After the driving component (201) corresponding to the positioning component (306) is started through step S2, the two corresponding positioning vertical bars (3061) respectively drive the positioning horizontal bar (3062) and the positioning ear plate (3063) to move closer to each other. The two positioning ear plates (3063) drive the two positioning bars (3064) to fit together and form a conveying channel through the two positioning grooves (3065), so that the two positioning bars (3064) clamp and assist in positioning the wire material. The wire material continues to be conveyed through the conveying channel formed by the two positioning grooves (3065). S4. Simultaneously, after the drive unit (201) corresponding to the coiling component (302) and the limiting component (303) is started through step S2, on the one hand, the moving bar (3021) drives the coiling motor (3023), the first clamp (3022), and the column (3024) to move towards the feeding component (301). On the other hand, the limiting bar (3031) drives the limiting horizontal bar (3032), the limiting ear plate (3033), the vertical rod (3034), the second clamp (3035), and the heat sink (307) to move towards the feeding component (301) synchronously until the first clamp (3022) and the second clamp (3035) are in contact with each other, and the wire material passes through the first clamp (3022) and the second clamp (3035). The two clamps (3035) continue to transport the material at the middle position. During this process, the micro cylinder (3071) in the heat sink (307) is activated. The output end of the micro cylinder (3071) moves the lifting block (3072), the extrusion plate (3073) and the sponge block (3074) toward the wire material until the two sponge blocks (3074) clamp and adhere the two sides of the wire material. Then, the micro oil pump (3075-2) extracts the oil from the micro oil storage box (3075-1) through the oil extraction pipe (3075-3) and transports it to the sponge block (3074) through the delivery pipe, wetting the sponge block (3074) so ​​that the sponge block (3074) lubricates and cools the wire material. S5. If the wire material has different thicknesses or needs to be flipped, the wire material can push the sponge blocks (3074) and extrusion plates (3073) on both sides in opposite directions, so that the slide bar (3072-2) slides in the guide groove (3072-1). At this time, the micro spring (3072-3) is in a compressed state, thus adapting to wire materials of different thicknesses. S6. Subsequently, the winding motor (3023) drives the column (3024) to rotate, and the wire material between the first clamp (3022) and the second clamp (3035) is bent. By controlling the rotation angle of the winding motor (3023), the bending angle of the wire material can be controlled over a wide range. S7. If it is necessary to bend the wire material in a small range, the wire material should first be kept in the middle of the second clamp (3035) for conveying. The column (3024) stops rotating. Then, it is started by the drive (201) corresponding to the bending part (304). The bending vertical bar (3041), bending horizontal bar (3042), bending ear plate (3043) and bending bar (3044) in the bending part (3044) move as a whole. The arc surface (3045) on the bending bar (3044) moves closer to the wire material and squeezes the wire material according to the requirements. During the continuous conveying process, the arc surface (3045) continuously applies pressure, and the wire material forms a small range of bending angle. S8. Finally, the wire material is bent into the required shape by feeding the feeder (301) and bending the coiler (302) in a wide range, and bending the bending member (304) in a small range. Then the drive member (201) and guide member (202) corresponding to the breaking member (305) are activated, and the cutting ends (3055) of the two breaking cutters (3054) approach each other to cut off and separate the formed wire material workpiece from the unformed wire material.
