[0086] Step one, the worker places the iron sheet wire in the machine body 102, and the iron sheet wire conveying mechanism is installed in the machine body 102, thereby completing the conveying of the iron sheet wire. Then the iron sheet wire is continuously sent out from the machine body 102 through the rotating hole 3014 and along the conveying port 3017 of the rotating head 3013.

[0087] Step two, the driving motor 2011 in the driving part 201 is started, and the driving motor 2011 drives the corresponding cam 2012 to start rotating. On the one hand, the protruding part of the cam 2012 extrudes 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 the sliding block 2024 on the sliding rail 2021 and moves towards the discharging part 301.

Conversely, if the push rod 2014 is not extruded by the protruding part of the cam 2012, the corresponding fixed block 2025 and the sliding block 2024 will cancel the pushing on the sliding rail 2021. Due to the characteristics of the pneumatic spring rod 2022, the pneumatic spring rod 2022 will pull back the corresponding sliding block 2024 and move away from the discharging part 301. The pneumatic spring rod 2022 is in a free state and returns to the normal form.

[0088] Step three, the driving part 201 corresponding to the curling part 302 and the limiting part 303 is started through the step of S2, on the one hand, the supporting rod 3021 drives the clamp 3022, the rotary motor 3023 and the torsion column 3024 to move towards the discharging part 301, on the other hand, the limiting vertical block 3031 drives the limiting horizontal block 3032, the limiting plug block 3033, the extension bar 3034 and the limiting clamp 3035 to move towards the discharging part 301 synchronously, until the clamp 3022 and the limiting clamp 3035 are attached to each other, in this process, the iron sheet wire passes through the middle position of the clamp 3022 of the clamp 3022 and the limiting clamp 3035, so as to achieve the purpose of limiting the iron sheet wire, then the iron sheet wire continues to be transported outside the machine body 102.

[0089] Step four, at the same time, the output end of the rotary motor 3023 drives the torsion column 3024 to rotate, the iron sheet wire at the middle position of the clamp 3022 and the limiting clamp 3035 is bent, and by controlling the rotation angle of the rotary motor 3023, the bending angle of the iron sheet wire can also be controlled in a large range.

[0090] Step five, then, the driving part 201 corresponding to the supporting part 304, the cutting part 306 and the arc pressing part 308 is started through the step of S2, since the curling part 302 and the limiting part 303 have bent the iron sheet wire to a certain bending shape, when the supporting part 304, the cutting part 306 and the arc pressing part 308 move, the curling part 302 and the limiting part 303 gradually move away from the discharging part 301 through the corresponding driving part 201, the rotating column 3012 drives the rotating head 3013 and the iron sheet wire to deflect in angle; on the one hand, the supporting vertical block 3041 drives the supporting horizontal block 3042, the supporting plug block 3043 and the supporting bar 3044 to move towards the discharging part 301, the inclined surface 3045 at one end of the supporting bar 3044 is attached to the wide surface of the iron sheet wire to support the iron sheet wire, on the other hand, the cutting vertical block 3061 drives the cutting horizontal block 3062, the cutting plug block 3063 and the carrier 3064 to move towards the discharging part 301 synchronously, in this process, the roller 3065 is inserted into the U-shaped groove formed by the iron sheet wire, at the same time, the arc pressing vertical block 3081 drives the arc pressing horizontal block 3082, the arc pressing plug block 3083 and the arc pressing bar 3084 to move towards the discharging part 301, the arc pressing bar 3084 with the arc pressing surface 3086 on the arc pressing plate 3085 presses the other wide surface of the iron sheet wire, so that the curvature of the U-shaped groove is consistent with the curvature of the outer wall of the roller 3065.

[0091] Step six, then, the support 304, cutting 306 and pressure arc piece 308 by the corresponding drive 201 gradually away from the discharge piece 301, rotating column 3012 rotating head 3013 and iron sheet wire deflection back to the initial angle, curl 302 and limiting piece 303 continue to iron sheet wire limiting and bending, iron sheet wire continue to outside the machine body 102 conveying.

[0092] Step seven, finally, with the corresponding drive 201 of the joint piece 307, angle piece 305 and cutting piece 306 through the step of S2 start, curl 302 and limiting piece 303 again by the corresponding drive 201 gradually away from the discharge piece 301, rotating column 3012 rotating head 3013 and iron sheet wire angle deflection again; on the one hand, the joint vertical block 3071 driven joint horizontal block 3072, joint plug block 3073 and joint strip 3074 to the discharge piece 301 move, the notch 3075 on the joint strip 3074 and the wide surface of iron sheet wire each other fit, avoid the iron sheet wire movement, so as to achieve the purpose of limiting.

[0093] Step eight, on the other hand, the angle vertical block 3051 driven angle horizontal block 3052, angle plug block 3053 and angle strip 3054 to the discharge piece 301 move, the arc surface 3055 on the angle strip 3054 and the narrow surface of iron sheet wire each other fit, because the cutting piece 306 and angle piece 305 is opposite setting, therefore, cutting piece 306 on iron sheet wire cutting, angle piece 305 is subjected to greater extrusion force, thus achieving the purpose of support.

[0094] Step nine, at the same time, cutting vertical block 3061 again driven cutting horizontal block 3062, cutting plug block 3063 and carrier 3064 synchronous to the discharge piece 301 move, in the process, cutting tool 3066 to the wide surface of iron sheet wire cutting, cutting separation of the iron sheet wire workpiece and the iron sheet wire raw material after bending.

2. A method for bending and forming a sheet spring, wherein the sheet spring bending and forming mold according to claim 1 is characterized in that, Includes the following steps: S1. The staff places the iron sheet wire inside the machine body (102) and the iron sheet wire is conveyed by the iron sheet wire conveying mechanism installed inside the machine body (102). Then the iron sheet wire is continuously fed out from the machine body (102) through the rotating hole (3014) and along the conveying port (3017) of the rotating head (3013). S2. The drive motor (2011) in the drive unit (201) is started. 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 fixing block (2025) and slider (2024) on the slide rail (2021) and moves them toward the discharge part (301). During this process, the slider (2024) drives the pneumatic spring. When the spring rod (2022) is stretched, the pneumatic spring rod (2022) is in a stretched state. Conversely, if the push rod (2014) is not squeezed by the protruding part of the cam (2012), the corresponding fixed block (2025) and slider (2024) will cancel the push on the slide 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 discharge part (301). The pneumatic spring rod (2022) is in a free state and returns to its normal shape. S3. After the drive unit (201) corresponding to the coiling part (302) and the limiting part (303) is started through step S2, on the one hand, the support rod (3021) drives the clamp (3022), the rotary motor (3023) and the torsion column (3024) to move towards the discharge part (301). On the other hand, the limiting vertical block (3031) drives the limiting horizontal block (3032), the limiting insert block (3033), the extension bar (3034) and the limiting clamp (3035) to move towards the discharge part (301) simultaneously until the clamp (3022) and the limiting clamp (3035) are in contact with each other. During this process, the iron sheet wire passes through the middle position of the clamp (3022) of the clamp (3022) and the limiting clamp (3035), thereby achieving the purpose of limiting the iron sheet wire. Then the iron sheet wire continues to be conveyed to the outside of the machine body (102). S4. At the same time, the output end of the rotary motor (3023) drives the torsion column (3024) to rotate, and the iron sheet wire in the middle position of the clamp (3022) and the limit clamp (3035) is bent. Furthermore, by controlling the rotation angle of the rotary motor (3023), the bending angle of the iron sheet wire can be controlled over a wide range. S5. Immediately following, after the driving component (201) corresponding to the support component (304), the cutting component (306), and the arc pressing component (308) is activated through step S2, since the coiling component (302) and the limiting component (303) have bent the iron sheet wire into a certain curved shape, when the support component (304), the cutting component (306), and the arc pressing component (308) move, the coiling component (302) and the limiting component (303) gradually move away from the discharge component (301) through the corresponding driving component (201), and the rotating column (3012) drives the rotating head (3013) and the iron sheet wire to deflect at an angle; on the one hand, the supporting vertical block (3041) drives the supporting horizontal block (3042), the supporting insert block (3043), and the supporting bar (3044) to move towards the discharge component (301), and the supporting bar (3044) one The beveled surface (3045) of the end fits against the wide surface of the iron sheet wire to support it. On the other hand, the cutting vertical block (3061) drives the cutting horizontal block (3062), the cutting insert block (3063) and the carrier (3064) to move towards the discharge part (301) simultaneously. During this process, the roller (3065) is inserted into the U-shaped groove of the iron sheet wire that has been bent. At the same time, the pressing vertical block (3081) drives the pressing horizontal block (3082), the pressing insert block (3083) and the pressing strip (3084) to move towards the discharge part (301). The pressing strip (3084) and the pressing surface (3086) on the pressing plate (3085) press against the other wide surface of the iron sheet wire, so that the curvature of the U-shaped groove is consistent with the curvature of the outer wall of the roller (3065). S6. Subsequently, the support (304), cutting (306) and arc pressing (308) gradually move away from the discharge part (301) through the corresponding driving part (201). The rotating column (3012) drives the rotating head (3013) and the iron sheet wire to deflect back to the initial angle. The coiling part (302) and the limiting part (303) continue to limit and bend the iron sheet wire. The iron sheet wire continues to be conveyed to the outside of the machine body (102). S7. Finally, after the driving component (201) corresponding to the snap-fit ​​component (307), the corner bend component (305), and the cutting component (306) is activated through step S2, the curling component (302) and the limiting component (303) are once again driven by the corresponding driving component (201) to gradually move away from the discharge component (301). The rotating column (3012) once again drives the rotating head (3013) and the iron sheet wire to deflect at an angle. On the one hand, the snap-fit ​​vertical block (3071) drives the snap-fit ​​horizontal block (3072), the snap-fit ​​insert block (3073), and the snap-fit ​​strip (3074) to move towards the discharge component (301). The cut (3075) on the snap-fit ​​strip (3074) fits against the wide surface of the iron sheet wire, preventing the iron sheet wire from moving, thereby achieving the purpose of limiting. S8. On the other hand, the vertical corner block (3051) drives the horizontal corner block (3052), the corner insert block (3053) and the corner strip (3054) to move toward the discharge part (301). The arc surface (3055) on the corner strip (3054) fits against the narrow surface of the iron sheet wire. Since the cutting part (306) and the corner part (305) are set opposite to each other, when the cutting part (306) cuts the iron sheet wire, the corner part (305) is subjected to a large compressive force, thereby achieving the purpose of support. S9. At the same time, the cutting vertical block (3061) once again drives the cutting horizontal block (3062), the cutting insert block (3063) and the carrier (3064) to move synchronously toward the discharge part (301). During this process, the cutting tool (3066) cuts toward the wide side of the iron sheet wire, separating the formed iron sheet wire workpiece from the unbent iron sheet wire raw material.
