Description

A continuous steel strip stamping forming device and process Technical Field

[0001] This invention relates to the field of steel strip processing equipment technology, specifically to a continuous steel strip stamping and forming device and process. Background Technology

[0002] As a core load-bearing component of the clutch braking system, the structural integrity and dimensional accuracy of the washing machine brake steel belt directly determine the stability of the braking response and its service life. This component typically integrates complex structural features such as positioning holes, heat dissipation grooves, and curved bending sections, and the manufacturing process requires multiple forming steps, including punching, grooving, bending, and cutting.

[0003] Currently, traditional production often uses single-stage stamping dies, requiring manual transfer of steel strips between multiple stamping presses to complete different processing steps. Even the forming of shaft holes alone requires a separate die for each step. Furthermore, during manual transfer, the steel strip needs repeated positioning and calibration, resulting in a long overall processing time. Although some equipment attempts to integrate die functions, such as combining the forming of multiple holes on the steel strip into a single step, such improvements are limited to the punching stage and do not achieve continuous connection with subsequent processes such as bending and cutting. Multiple transfer and positioning operations are still required, leading to low overall processing efficiency. Summary of the Invention

Punch rod one and punch rod two are located inside the punching channels. The slotting block is located inside the slotting channel, and the length of the slotting block is less than the length of the slotting channel. The primary bending punch and the secondary bending punch are located inside the bending channel, and the lengths of both the primary and secondary bending punches are less than the length of the bending channel. The pressure rod is located inside the pressing channel, and the maximum diameter of the pressure rod is less than the width of the pressing channel. The stripping block is located inside the stripping channel. The cutting knife is located inside the cutting channel. The pressure plate has connecting holes, and a connecting rod is connected to the upper die. The cross-sectional shape of both the connecting rod and the connecting hole is T-shaped. The pressure plate is slidably connected to the connecting rod through the connecting holes.

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] As shown in Figures 1 to 10, a continuous steel strip stamping forming apparatus of the present invention includes a bottom mold 10, on which a steel strip 11 is disposed. The steel strip 11 continuously feeds along the length direction of the bottom mold 10. At least one limiting structure is provided on the bottom mold 10 to limit the position of the steel strip 11, preventing positional deviation during movement and ensuring the positioning accuracy of subsequent stamping processes. An upper mold 20 is disposed above the bottom mold 10, and two forming components are symmetrically arranged on the upper mold 20. The forming components include a punching component, ... The upper die 20 is equipped with a punching block 214, a double bending assembly, and a multiple pressing assembly. The punching assembly, punching block, double bending assembly, multiple pressing assembly, and punching assembly are arranged sequentially along the feed direction of the steel strip 11. The forming assembly moves along the width direction of the upper die 20 to perform punching, punching, double bending, and multiple pressing operations on the steel strip 11 in sequence. Two sets of adjustment structures are symmetrically arranged on the upper die 20. The forming assembly is connected to the adjustment structure. The forming assembly and the adjustment structure correspond one-to-one. The adjustment structure is used to adjust the position of the forming assembly.

[0029] The steel strip 11 moves continuously along the length of the bottom die 10. The limiting structure prevents the steel strip 11 from shifting position during the movement. Before stamping the steel strip 11, the position of the forming component is adjusted so that the forming component can perform punching, grooving, bending and pressing operations on specific positions on the steel strip 11. When the steel strip 11 moves, the forming operations of punching, grooving, bending twice and pressing multiple times are completed on the continuously fed steel strip 11 in sequence. Finally, the blanking and stripping component realizes the blanking and stripping of the finished product.

[0030] As shown in Figures 4 to 6, the adjustment structure includes a lead screw 21 rotatably connected to the upper mold 20. The outer surface of the lead screw 21 is threaded with a mounting slide 22. The bottom side of the mounting slide 22 is connected to the molding component. The bottom side of the upper mold 20 has a mounting groove 201. A guide slider is fixedly installed on the inner wall of the mounting groove 201. A guide groove 221 is opened on one side of the mounting slide 22. The guide slider is located inside the guide groove 221 and is slidably connected to the guide groove 221.

[0031] When the position of the forming component needs to be adjusted, the lead screw 21 rotates around its own axis. Since the mounting slide 22 is threadedly connected to the lead screw 21, the rotational motion of the lead screw 21 is converted into linear motion of the mounting slide 22 along the axis of the lead screw 21 under the constraint of the guide slider and the guide groove 221. When the lead screw 21 rotates forward, the mounting slide 22 moves in one direction; when the lead screw 21 rotates in reverse, the mounting slide 22 moves in the opposite direction, thereby realizing the position adjustment of the forming component to meet the stamping forming operation of steel strips of various specifications.

[0032] As shown in Figures 8 and 9, the limiting structure includes a second lead screw 12 rotatably connected to the bottom mold 10. A slider 13 is threadedly connected to the outer surface of the second lead screw 12. A sleeve 14 is fixedly installed on the top of the slider 13. A threaded rod 15 is threadedly connected to the inner wall of the sleeve 14. A limiting wheel 16 is rotatably connected to the top of the threaded rod 15. A groove is opened on one side of the bottom mold 10. The slider 13 is located inside the groove and is slidably connected to the groove.

[0033] Rotating the lead screw 12 can convert the rotational motion into the lateral linear motion of the slider 13, which drives the sleeve 14, threaded rod 15 and limit wheel 16 to move closer to or away from the steel belt 11, thereby adjusting the lateral spacing of the limit wheel 16 to fit steel belts of different widths, so that the limit wheel 16 contacts the side of the steel belt 11, and restricts the left and right deviation of the steel belt through physical blocking.

[0034] As shown in Figures 4 to 6, the punching assembly includes a punch rod 24 and a punch rod 25 mounted on the mounting slide 22. The punch rods 24 and 25 move along the width direction of the mounting slide 22 to punch two holes in the steel strip 11. The double bending assembly includes two bending rods 26 mounted along the direction of the mounting slide 22. One bending rod 26 is connected to a primary bending punch 27 at its end, and the other bending rod 26 is connected to a secondary bending punch 28 at its end. The multiple pressing assembly includes multiple mounting rods 29 and a flattening rod 211 mounted along the length direction of the mounting slide 22. The ends of the multiple mounting rods 29 are connected to pressure rods 210. The ends of the multiple pressure rods 210 are provided with bevels. The length of the multiple pressure rods 210 increases progressively along the feed direction of the steel strip 11.

[0035] When the continuously fed steel strip 11 moves to the punching station, the upper die 20 drives the punch rod 24, punch rod 25, and the slotting block 214 to punch downwards simultaneously. The two punch rods act simultaneously at the preset positions on the steel strip 11, breaking through the strength of the steel strip material through the punching force, accurately punching two holes on the steel strip 11 and punching a groove at the edge of the steel strip 11 to facilitate subsequent bending of the steel strip. When the steel strip 11 is fed to the bending station, the primary bending punch 27 first acts downwards on the preset area of ​​the side of the steel strip 11 after the slotting, applying bending force to the side of the steel strip through the specific contour of the punch, so that the side of the steel strip completes the initial bending from the horizontal state to the vertical direction, making the steel strip 11 in an inclined state; then the steel strip 11 continues to feed, and the secondary bending punch 28 acts on the side of the steel strip after the initial bending, further... The bending force is applied step by step to correct the deviation of the initial bend, and the side of the steel strip is gradually adjusted to a completely vertical state. After the steel strip 11 (with the side in a vertical state) after the second bend enters the pressing station, it contacts each pressure bar 210 in sequence with continuous feeding. The pressure bars 210 of different lengths apply pressure from the root to the top of the vertical part of the side of the steel strip through the end slope. The guide effect of the slope makes the vertical side slowly tilt towards the middle of the steel strip 11. Due to the gradient setting of the pressure bar length, the tilt angle gradually increases to avoid stress concentration in the material due to a single tilt. When the steel strip 11 moves to the pressing bar 211 station, the pressing bar 211 applies uniform pressure downward to flatten the already tilted side of the steel strip, so that it fits tightly with the middle plane of the steel strip 11, completing the integrated forming of the side and the middle.

[0036] It should be noted that the flattening bar 211 can be plate-shaped to increase the contact area with the inclined part of the steel strip 11, eliminate wrinkles that may be generated during the inclination process, and ensure the flatness of the mating surface.

[0037] As shown in Figure 4, the punching and stripping assembly includes stripping blocks 212 and cutting blades 213 distributed along the feed direction of the steel strip 11.

[0038] When the flattened steel strip 11 continues to be fed to the station corresponding to the stripping block 212, the upper die 20 drives the stripping block 212 to press downwards, precisely forming a stripping groove at a preset position in the middle of the steel strip 11. This stripping groove provides a stress concentration point for subsequent punching and separation, reducing the difficulty of punching and ensuring a smooth cut. Subsequently, the steel strip 11, with the formed stripping groove, continues to be fed to the station corresponding to the punching cutter 213. The punching cutter 213 applies a punching force to the stripping groove position, and utilizes the stress concentration effect at the stripping groove to quickly punch the steel strip 11 along the stripping groove, so that the continuously formed steel strip is separated into individual independent washing machine brake steel strip finished products, realizing the integrated completion of stamping and stripping, ensuring the efficiency of finished product separation and the quality of the cut.

[0039] As shown in Figures 4 to 7, a pressure plate 40 is provided between the upper die 20 and the steel strip 11. Two punching channels 401, two slotting channels 402, four bending channels 403, multiple pressing channels 404, a stripping channel 405, and a breaking channel 406 are provided on one side of the pressure plate 40. These channels are distributed sequentially along the feed direction of the steel strip 11. Punch rod 1 24 and punch rod 25 are located inside the punching channel 401, and the slotting block 214 is located inside the slotting channel 402. Furthermore, the length of the punch block 214 is less than the length of the punch channel 402. The primary bending punch 27 and the secondary bending punch 28 are located inside the bending channel 403, and the lengths of the primary bending punch 27 and the secondary bending punch 28 are both less than the length of the bending channel 403. The pressure bar 210 is located inside the lower pressure channel 404, and the maximum diameter of the pressure bar 210 is less than the width of the lower pressure channel 404. The stripper block 212 is located inside the stripper channel 405. The punch cutter 213 is located inside the punch cutter channel 406. A connecting component is provided between the pressure plate 40 and the upper die 20. The connecting component is used to connect the pressure plate 40 and the upper die 20.

[0040] The connecting assembly includes a connecting hole 407 formed on the pressure plate 40 and a connecting rod 215 connected to the upper mold 20. The cross-sectional shape of both the connecting rod 215 and the connecting hole 407 is T-shaped. The pressure plate 40 is slidably connected to the connecting rod 215 through the connecting hole 407.

[0041] The connecting rod 215 and connecting hole 407 allow the pressure plate 40 to slide along the connecting rod 215, ensuring that the pressure plate contacts the steel strip before the forming component when the upper die 20 moves downward, applying a uniform preload to the steel strip. As the upper die 20 moves downward, punches 1 24 and 25 punch the steel strip 11 through punching channel 401, and grooving block 214 grooves the edge of the steel strip 11 through grooving channel 402. First bending punch 27 and second bending punch 28 bend the edge of the steel strip 11 twice through bending channel 403. Pressure rod 210 presses the edge of the steel strip 11 multiple times through pressing channel 404. Stripping block 212... The stripping channel 405 passes through the stripping channel and punches a stripping groove in the middle of the steel strip 11. The cutting knife 213 passes through the cutting channel 406 and performs a cutting operation on the steel strip 11. When adjusting the position of the mounting slide 22, punch rod 1 24 and punch rod 25 can move inside the punching channel 401, the grooving block 214 can move inside the grooving channel 402, the first bending punch 27 and the second bending punch 28 can move inside the bending channel 403, and the pressure rod 210 can move inside the pressing channel 404, ensuring that punch rod 1 24, punch rod 25, grooving block 214, first bending punch 27, second bending punch 28 and pressure rod 210 have sufficient space to move.

[0042] It also includes a base 50, on which a waste trough 501 is provided. The bottom side of the waste trough 501 is inclined. A waste bin 51 is provided on one side of the base 50. The waste bin 51 is positioned corresponding to the waste trough 501. The bottom mold 10 is provided with a discharge channel 101 and a discharge channel 202. The discharge channel 101 is positioned corresponding to the punch block 214, and the size of the discharge channel 101 is larger than the size of the punch block 214. The discharge channel 202 is positioned corresponding to the stripper block 212, and the size of the discharge channel 202 is larger than the size of the stripper block 212. Both the discharge channel 101 and the discharge channel 202 are connected to the waste trough 501.

[0043] The waste material pressed by the punching block 214 and the stripping block 212 enters the interior of the waste trough 501 through the discharge channel 101 and the discharge channel 202. Under the action of the waste trough 501, the waste material enters the interior of the waste bin 51 for collection, so that the device can automatically collect the waste material.

[0044] A collection box 52 is provided on the side of the base 50 away from the waste bin 51. The collection box 52 is tilted and the top of the collection box 52 corresponds to the end of the steel belt 11. The collection box 52 is used to collect the individual finished washing machine brake steel belts after separation.

[0045] A support base 53 is connected to the base 50. A drive component 54 is provided on the support base 53. The drive component 54 is connected to the upper mold 20. The drive component 54 is used to drive the upper mold 20 to move up and down reciprocally. A guide rail is installed on the support base 53. The upper mold 20 is slidably connected to the guide rail. The guide rail is used to ensure that the upper mold 20 can only move in the vertical direction.

[0046] A continuous steel strip stamping process includes the following steps: S1. According to the specifications of the washing machine brake steel strip to be processed, rotate the second lead screw to adjust the lateral spacing of the limit wheels 16, and adjust the height of the limit wheels 16 through the threaded rod 15; rotate the first lead screw 21 to drive the mounting slide 22 to move, and adjust the positions of the first punch 24, the second punch 25, the punching block 214, the first bending punch 27, the second bending punch 28, and the pressure rod 210; S2.

The steel strip 11 is fed sequentially to complete punching and grooving, two bending, multiple pressing and flattening, and blanking. In the material forming process, punch rod 1 24 and punch rod 25 punch out positioning holes, punching block 214 punches out bending grooves, first bending punch 27 bends the side of steel strip 11 to an inclined state, second bending punch 28 corrects the deviation to a vertical state, pressure rod 210 gradually applies pressure to make the side tilt towards the middle of steel strip 11, flattening rod 211 flattens and fits the side, stripping block 212 punches out stripping groove, and cutting knife 213 cuts steel strip 11 along stripping groove; S4, the single finished steel strip 11 after being cut enters collection box 52; the waste generated by punching and stripping enters waste trough 501 through discharge channel 1 101 and discharge channel 2 102, and is finally collected in waste bin 51, thus completing the stamping and forming operation of washing machine brake steel strip.
