Description

Technical Field

[0001] This invention relates to the field of sheet metal stamping equipment technology, specifically to an integrated metal stamping and bending forming machine for electrical distribution boxes. Background Technology

[0002] Distribution boxes are electrical equipment characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, lack of site restrictions, widespread application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. They are constructed by assembling switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet according to electrical wiring requirements. Commonly used distribution boxes can be categorized into fixed panel switchgear, protective (i.e., enclosed) switchgear, drawer-type switchgear, and power and lighting distribution control boxes, among others.

[0003] The metal sheet material of the distribution box is the base material used in the production of distribution boxes. After processes such as cutting, stamping, bending, welding and assembly, and surface treatment, the distribution box is formed.

[0004] Chinese patent document CN221715348U discloses a bending machine for processing sheet metal for electrical distribution boxes, including a worktable. Four support legs are fixedly installed at the lower end of the worktable, and a connecting plate is fixedly installed at the left end of the right support legs. A bending die is fixedly installed at the upper end of the worktable, and a support frame is fixedly installed at the upper end of the worktable. A sliding groove is formed on the front side of the upper end of the support frame, and an adjusting component is disposed within the sliding groove. A positioning bolt is movably connected to the lower end of the adjusting component, and a movable plate is fixedly installed at the lower end of the positioning bolt. A sponge block is fixedly installed at the lower end of the movable plate. The outer wall of the sponge block and the inner wall of the bending die are on the same horizontal plane. The upper part of the support frame... A push cylinder is fixedly installed at one end, and a pressure head is fixedly installed at the output end of the push cylinder. A support plate is fixedly installed on both the front and rear sides of the upper end of the worktable, and a plate is placed on the support plate. The adjustment component includes a lead screw, a servo motor is fixedly installed at the right end of the lead screw, and an adjustment plate is threaded to the outer surface of the lead screw. The adjustment plate is L-shaped. The servo motor is fixedly connected to the right end of the support frame. The lead screw is movably connected in a slide groove. The positioning bolt and the adjustment plate are movably connected. An outlet is opened on the upper right side of the worktable. A storage box is placed on the upper end of the connecting plate, and the storage box is located below the worktable. The upper surface of the support plate and the upper surface of the bending die are on the same horizontal plane.

[0005] During operation, the plate is placed on the bending die. The pressure head is pushed downward by the cylinder and comes into contact with the surface of the plate, applying pressure. The pressure head, together with the bending die, bends the plate. A servo motor drives the lead screw to rotate, which in turn moves the adjusting plate along the lead screw from left to right. This causes the sponge block to move to the right and enter the bending die. Since the outer wall of the sponge block and the inner wall of the bending die are on the same horizontal plane, the sponge block has adsorption properties and can absorb most of the impurities in the groove of the bending die. The sponge block pushes the impurities to the right out of the bending die and they fall into the storage box through the outlet for storage.

[0006] In the aforementioned technology, when bending the sheet metal, the operator needs to adjust and tidy the position of the sheet metal multiple times to ensure that the position to be bent is parallel to the bending die before bending. On the one hand, this results in low bending efficiency of the sheet metal; on the other hand, the poor matching accuracy between the position to be bent and the bending die leads to poor bending quality of the sheet metal. Summary of the Invention

[0007] This invention provides a metal stamping and bending integrated forming machine for distribution boxes, aiming to solve the technical problems in the prior art where, when bending sheet metal, operators need to adjust and align the sheet metal multiple times to ensure that the position to be bent is parallel to the bending die before bending. This results in low bending efficiency and poor matching accuracy between the sheet metal position and the bending die, leading to poor bending quality.

[0008] This invention discloses a metal stamping and bending integrated forming machine for electrical distribution boxes, comprising a forming machine body, a bending die and a stamping die disposed on the forming machine body, a bending table for placing sheet metal on the forming machine body, and a feeding device on one side of the forming machine body. The feeding device includes a frame, a sorting component and a pushing component disposed on the frame, the sorting component including a sorting frame disposed on the frame and sorting rods disposed on the sorting frame for neatly processing the four edges of the sheet metal, the sorting frame having a clearance groove for the sheet metal to pass through at one end facing the forming machine body, multiple sorting rods disposed on the sorting frame, the top of the sorting rods being inclined away from the sorting frame in a vertically upward direction, the sheet metal being placed between the multiple sorting rods from the top of the multiple sorting rods and sliding down along the multiple sorting rods for gradual neat processing, the neat processing being completed after the sheet metal reaches the pushing component, the pushing component pushing the sheet metal horizontally to the bending table for bending processing.

[0009] Beneficial effects: With the feeding device, when the sheet metal needs to be bent, the sheet metal is first placed from the top of multiple sorting rods between them. Then, the sheet metal slides down along the sorting rods. During the sliding process, the sorting rods gradually straighten the sheet metal, and the straightening is completed when it reaches the pushing component. At this point, the sheet metal is neatly laid on the sorting rack, completing the straightening operation. Then, the pushing component works, pushing the sheet metal horizontally along the sorting rack and onto the bending table. The pushing component continues to push the sheet metal, so that the position to be bent is between the bending die and the stamping die for bending. On the one hand, it eliminates the need for operators to adjust the sheet metal position multiple times, improving the efficiency of sheet metal feeding and adjustment, thereby improving the bending efficiency. On the other hand, compared with the manual adjustment of the fit between the sheet metal position to be bent and the bending die, this device has a higher accuracy in adjusting the fit between the sheet metal position to be bent and the bending die, thereby improving the bending quality of the sheet metal.

[0010] Preferably, the sorting rod includes a vertical part disposed on the sorting frame and a sorting part disposed at the top of the vertical part for neatly processing the board material, wherein the sorting part is inclined away from the sorting frame in a vertically upward direction.

[0011] Beneficial effects: By setting up vertical sections and sorting sections, when the board is located at multiple sorting sections and slides down vertically, the board is neatly processed by multiple sorting sections. When the board reaches the vertical section, it can continue to slide down vertically to complete the sorting of the board, making the neat processing of the board more convenient and efficient.

[0012] Preferably, the pushing component includes a push plate that slides horizontally on the sorting rack and a driver disposed on the sorting rack for driving the push plate to slide, wherein the output end of the driver is connected to the push plate.

[0013] Preferably, a mounting plate is horizontally arranged on the frame, and multiple sorting racks are spaced apart on the mounting plate along the axial direction of the mounting plate.

[0014] Beneficial effects: The installation tray allows for the setup of multiple sorting racks, enabling the neat processing of multiple boards and facilitating efficient bending of the boards in the subsequent process.

[0015] Preferably, the mounting plate is provided with a connecting device, which includes a rotating block and a connecting rod that are rotatably fitted on the mounting plate along the axial direction of the mounting plate. One end of the connecting rod is connected to the rotating block, and the other end is connected to the sorting rack.

[0016] Beneficial effects: By setting up the connecting device, when the rotating block rotates, it can drive the connecting rod to rotate, and the connecting rod drives the sorting frame to rotate, thereby realizing the adjustment of the position of multiple feeding devices and realizing the feeding of multiple boards.

[0017] Preferably, the connecting rod includes a fixed part connected to the rotating block and a sliding part that slides radially along the mounting plate on the fixed part, and the mounting plate is provided with an adjustment device for driving the sliding part to make sliding adjustments.

[0018] Beneficial effects: By adjusting the device, when the sorting rack rotates toward the bending table, the adjusting device can drive the sliding part to slide along the fixed part toward the bending table, thereby rotating the board to the bending table and making the board closer to the bending table, which facilitates the subsequent bending processing of the board. At the same time, it can save the space required for the feeding device to work.

[0019] Preferably, the adjusting device includes an adjusting rod mounted on the sorting rack and an adjusting assembly for driving the adjusting rod to slide.

[0020] Preferably, the adjusting assembly includes a pressing plate installed in the mounting plate and an elastic element fitted on the fixed part and used to drive the sliding part to slide closer to the fixed part. One end of the elastic element is connected to the fixed part, and the other end is connected to the sliding part. One end of the pressing plate is inclined away from the rotating block along the rotation direction of the rotating block. When the adjusting rod rotates with the rotating block and rotates along the pressing plate, the pressing plate pushes the adjusting rod to drive the sliding part to slide away from the fixed part.

[0021] Preferably, the fixing part slides vertically into the rotating block, and a vibration device is provided inside the mounting plate. The vibration device includes an elastic element two for driving the fixing part to slide vertically downward and a vibration plate provided inside the mounting plate. One end of the elastic element two is connected to the fixing part, and the other end is connected to the rotating block. The vibration plate is provided with multiple extrusion arc surfaces for pushing the adjusting rod to rise vertically.

[0022] Beneficial effects: By setting up the vibration device, when the adjusting rod rotates to the extrusion arc surface of the vibrating plate, the extrusion arc surface presses against the adjusting rod, causing the adjusting rod to rise vertically. The adjusting rod drives the sorting frame and connecting rod to rise, and stretches the second elastic element. When the adjusting rod rotates to the upper surface of the vibrating plate, the second elastic element releases its elastic restoring force, causing the connecting rod, sorting frame and adjusting rod to fall, thereby causing the sorting frame to vibrate slightly, which in turn causes the board to vibrate, improving the neatness and efficiency of the board processing.

[0023] Preferably, a drive device is provided inside the frame. The drive device includes a rotating rod connected to the rotating block and used to drive the rotating block to rotate, and a drive component disposed on the frame and used to drive the rotating rod to rotate. The output shaft of the drive component is connected to the rotating rod.

[0024] The beneficial effects of this invention are as follows: 1. In this invention, by setting up a feeding device, when the sheet metal needs to be bent, the sheet metal is first placed from the top of multiple sorting rods between multiple sorting rods. Then, the sheet metal can slide down along multiple sorting rods. During the sliding process, the multiple sorting rods can gradually tidy up the sheet metal, and the tidying is completed when it reaches the pushing component. At this time, the sheet metal can be neatly laid on the sorting frame, completing the tidying operation of the sheet metal. Then, the pushing component works, pushing the sheet metal to slide horizontally along the sorting frame and slide to the bending table. The pushing component continues to push the sheet metal to slide, so that the position of the sheet metal to be bent reaches between the bending die and the stamping die for bending processing. On the one hand, it eliminates the need for operators to adjust the position of the sheet metal multiple times, improving the feeding and adjustment efficiency of the sheet metal, thereby improving the bending efficiency of the sheet metal. On the other hand, compared with the manual adjustment of the fitting accuracy between the fitting accuracy of the sheet metal to be bent position and the bending die, this device has a higher fitting accuracy between the fitting accuracy of the sheet metal to be bent position and the bending die, thereby improving the bending processing quality of the sheet metal.

[0025] 2. In this invention, by setting up a vibration device, when the adjusting rod rotates to the extrusion arc surface of the vibration plate, the extrusion arc surface presses against the adjusting rod, causing the adjusting rod to rise in the vertical direction. The adjusting rod drives the sorting frame and connecting rod to rise, and stretches the second elastic element. When the adjusting rod rotates to the upper surface of the vibration plate, the second elastic element releases its elastic restoring force, causing the connecting rod, sorting frame and adjusting rod to fall, thereby causing the sorting frame to vibrate slightly, thereby causing the board to vibrate, improving the neatness and efficiency of the board.

[0035] 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.

[0036] Reference Figures 1-8This invention discloses a metal stamping and bending integrated forming machine for a power distribution box, comprising a forming machine body 1, a bending die 2, a stamping die 3, a bending table 4, and a feeding device 5, all mounted on the forming machine body 1. The bending die 2 is detachably mounted on the forming machine body 1, and the stamping die 3 is mounted on the forming machine body 1. The bending die 2 is located below the stamping die 3, and the stamping die 3 and the bending die 2 are arranged opposite each other in the vertical direction. A driving mechanism for driving the stamping die 3 to rise or fall in the vertical direction is mounted on the forming machine body 1. The bending table 4 is slidably fitted onto the forming machine body 1 along the length direction of the forming machine body 1. A limiting mechanism for limiting the sliding adjustment of the bending table 4 is provided on the bending table 4. The upper surface of the bending table 4 is adapted to the upper surface of the bending die 2, and the bending table 4 is used to place the sheet metal to be bent. The feeding device 5 is located on the forming machine body 1. On one side of the forming machine body 1, a conveying device (not shown in the figure) can be provided for conveying the sheet metal to the feeding device 5. When it is necessary to perform stamping and bending processing on rectangular sheet metal, the bending table 4 is first slidably adjusted on the forming machine body 1. After the adjustment is completed, the position of the bending table 4 is fixed by the limiting mechanism. Then, the feeding device 5 is moved to the position corresponding to the bending table 4. Then, the sheet metal is conveyed to the bending table 4 by the feeding device 5, and the bending position of the sheet metal is aligned with the top of the bending die 2. Then, the operator presses the sheet metal, and at the same time, the drive mechanism drives the stamping die 3 to descend. The stamping die 3 cooperates with the bending die 2 to bend the sheet metal. After the sheet metal is bent, the drive mechanism drives the stamping die 3 to rise. Then, the operator can take out the bent sheet metal to complete the bending operation of the sheet metal.

[0037] Reference Figure 2 , Figure 3 and Figure 4A mounting plate 6 is horizontally fixed on the frame 51. Multiple sorting frames 521 are spaced apart on the mounting plate 6 along its axial direction, and are evenly distributed. The feeding device 5 includes a frame 51, a sorting assembly 52 mounted on the frame 51, and a pushing assembly 53. The sorting assembly 52 includes a sorting frame 521 mounted on the frame 51 and sorting rods 522 mounted on the sorting frame 521 for neatly processing the four edges of the sheet metal. The sorting frame 521 has a U-shaped structure. A clearance groove 523 for the sheet metal to pass through is opened at one end of the sorting frame 521 facing the forming machine body 1. The clearance groove 523 is rectangular. The top of the sorting rods 522 is inclined upwards away from the sorting frame 521. Four sorting rods 522 are mounted on the sorting frame 521, and are respectively mounted on the four sides of the sorting frame 521. 2 includes a vertical part 524 fixedly mounted on a sorting frame 521 and a sorting part 525 integrally formed on the top of the vertical part 524 for neatly processing the sheet metal. The vertical part 524 is vertically positioned, and the sorting part 525 is inclined away from the sorting frame 521 in a vertically upward direction. When the sheet metal needs to be loaded, the sheet metal is first placed between the multiple sorting rods 522 from the top of the multiple sorting rods 522. Then the sheet metal slides down along the multiple sorting rods 522. During the sliding process, the sorting part 525 gradually performs neat processing. When the sheet metal reaches the vertical part 524 from the sorting part 525, the position adjustment of the sheet metal is completed, and it continues to slide along the vertical part 524. After the sheet metal reaches the pushing component 53, the neat processing is completed, and it abuts against the sorting frame 521. Then the pushing component 53 works, and the pushing component 53 pushes the sheet metal to slide horizontally and onto the bending table 4 for bending processing.

[0038] Among them, reference Figure 3 , Figure 4 and Figure 5The pushing component 53 includes a pushing plate 531 that slides horizontally on the sorting frame 521 and a driver 532 that is set on the sorting frame 521 and used to drive the pushing plate 531 to slide. The pushing plate 531 is a rectangular plate. The driver 532 is directly a cylinder. The cylinder body of the driver 532 is fixedly connected to the sorting frame 521. The output end of the driver 532 passes through the sorting frame 521 and is fixedly connected to the pushing plate 531. When the plate reaches the pushing plate 531, the driver 532 works, the output shaft of the driver 532 extends, the driver 532 drives the pushing plate 531 to slide and pushes the plate. The plate slides along the sorting frame 521 and slides out of the relief groove 523. Then the driver 532 continues to work, and drives the plate to slide onto the bending table 4 through the pushing plate 531. When the bending position of the plate corresponds to the top of the bending die 2, the driver 532 stops pushing the plate. Then the output shaft of the driver 532 retracts, and the driver 532 drives the pushing plate 531 to reset.

[0039] Reference Figure 4 , Figure 5 and Figure 6 The mounting plate 6 is provided with a connecting device 7. The connecting device 7 includes a rotating block 71 and a connecting rod 72 that are rotatably fitted on the mounting plate 6 along the axial direction of the mounting plate 6. The rotating block 71 is coaxially arranged with the mounting plate 6. The connecting rod 72 includes a fixed part 721 connected to the rotating block 71 and a sliding part 722 that is slidably fitted on the fixed part 721 along the radial direction of the mounting plate 6. The sliding part 722 is sleeved on the fixed part 721, and the end of the sliding part 722 away from the rotating block 71 is fixedly connected to the sorting frame 521.

[0040] Reference Figure 3 , Figure 6 and Figure 7The mounting plate 6 is equipped with an adjustment device 8 for sliding adjustment of the sliding part 722. The adjustment device 8 includes an adjustment rod 81 fixedly mounted on the sorting rack 521 and an adjustment assembly 82 for sliding the adjustment rod 81. The adjustment rod 81 is vertically arranged, and the bottom end of the adjustment rod 81 is provided with an arc-shaped surface. The adjustment assembly 82 includes a pressing plate 821 fixedly mounted in the mounting plate 6 and an elastic element 822 sleeved on the fixed part 721 and used to drive the sliding part 722 to slide closer to the fixed part 721. The pressing plate 821 is an arc-shaped plate, and one end of the pressing plate 821 is inclined away from the rotating block 71 along the rotation direction of the rotating block 71. The elastic element 822 is directly a spring. The elastic element 822 is fixedly connected at one end to the fixed part 721 and at the other end to the sliding part 722. When the rotating block 71 rotates, it drives the connecting rod 72 to rotate. The connecting rod 72 drives the sorting frame 521 to rotate. The sorting frame 521 drives the adjusting rod 81 to rotate. When the adjusting rod 81 rotates to the pressing plate 821 and rotates along the pressing plate 821, the pressing plate 821 can push the adjusting rod 81 to drive the sliding part 722 to slide away from the fixed part 721. When the sliding part 722 slides, it stretches the elastic element 822. When the adjusting rod 81 rotates away from the pressing plate 821, the elastic element 822 releases its elastic restoring force, driving the sliding part 722 to slide closer to the fixed part 721, so that the sliding part 722 returns to its original position.

[0041] Reference Figure 3 , Figure 5 and Figure 8The fixing part 721 slides vertically against the rotating block 71. A vibration device 9 is installed inside the mounting plate 6. The vibration device 9 includes an elastic element 91 that drives the fixing part 721 to slide vertically downwards, and a vibration plate 92 installed inside the mounting plate 6. The elastic element 91 is a spring, vertically positioned, with one end fixedly connected to the fixing part 721 and the other end fixedly connected to the rotating block 71. In the initial state, the elastic element 91 pulls the fixing part 721 to slide away from the top of the rotating block 71. The vibration plate 92 is an arc-shaped plate with arc-shaped surfaces at both ends. Multiple extrusion arc surfaces 921 are provided on the vibration plate 92 to push the adjusting rod 81 upwards vertically. When the sorting rack 521 rotates the adjusting rod 81 to the vibration plate 92, the adjusting rod 81... The adjusting rod 81 can rotate to the upper surface of the vibrating plate 92 and continue to rotate along the upper surface of the vibrating plate 92. When the bottom end of the adjusting rod 81 rotates to the extrusion arc surface 921, the extrusion arc surface 921 extrudes the adjusting rod 81, causing the adjusting rod 81 to drive the sorting frame 521 and the connecting rod 72 to rise. The connecting rod 72 stretches the elastic element 91. When the adjusting rod 81 continues to rotate along the extrusion arc surface 921, the extrusion arc surface 921 no longer extrudes the adjusting rod 81, and the elastic element 91 releases its elastic restoring force, causing the connecting rod 72, the sorting frame 521 and the adjusting rod 81 to fall. When passing through multiple extrusion arc surfaces 921 in sequence, the adjusting rod 81, the sorting frame 521 and the sorting rod 522 can vibrate slightly, thereby causing the plates between multiple sorting rods 522 to vibrate, so that the plates can be better and more neatly laid in the sorting frame 521.

[0042] Reference Figure 4 and Figure 6 A drive device 10 is installed inside the frame 51. The drive device 10 includes a rotating rod 101 fixedly connected to the rotating block 71 and used to drive the rotating block 71 to rotate, and a drive component 102 fixedly installed on the frame 51 and used to drive the rotating rod 101 to rotate. The rotating rod 101 is rotatably fitted on the frame 51 and the mounting plate 6. The drive component 102 is directly an electric motor, and the output shaft of the drive component 102 is fixedly connected to the rotating rod 101. When the drive component 102 is started, it can drive the rotating rod 101 to rotate, the rotating rod 101 drives the rotating block 71 to rotate, the rotating block 71 drives the connecting rod 72 and the sorting frame 521 to rotate, and thus drives the plate to rotate.

[0043] The implementation principle of the metal stamping and bending integrated forming machine for distribution box of the present invention is as follows: when it is necessary to stamp and bend the sheet metal, the bending table 4 is first slidably adjusted on the forming machine body 1. After the adjustment is completed, the position of the bending table 4 is fixed by the limiting mechanism. Then the feeding device 5 is moved to the position corresponding to the bending table 4. Next, the sheet material is placed between multiple sorting rods 522 located away from the extrusion plate 821 along the length of the forming machine body 1. The sheet material can slide downwards. Simultaneously, the drive unit 102 is activated, causing the rotating rod 101 to rotate. The rotating rod 101 drives the rotating block 71 to rotate, which in turn drives the connecting rod 72, the sorting frame 521, and the adjusting rod 81 to rotate, thereby causing the sheet material to rotate. When the sorting frame 521 drives the adjusting rod 81 to rotate to the vibrating plate 92, the adjusting rod 81 can rotate to the upper surface of the vibrating plate 92 and continue to rotate along the upper surface of the vibrating plate 92. When the bottom end of the adjusting rod 81 rotates to the extrusion plate... At the arc surface 921, the extrusion arc surface 921 presses against the adjusting rod 81, causing the adjusting rod 81 to drive the sorting frame 521 and the connecting rod 72 to rise. The connecting rod 72 stretches the elastic element 91. When the adjusting rod 81 continues to rotate along the extrusion arc surface 921, the extrusion arc surface 921 no longer presses against the adjusting rod 81. The elastic element 91 releases its elastic restoring force, causing the connecting rod 72, the sorting frame 521 and the adjusting rod 81 to fall. When passing through multiple extrusion arc surfaces 921 in sequence, the adjusting rod 81, the sorting frame 521 and the sorting rod 522 can vibrate slightly, thereby causing the plates between the multiple sorting rods 522 to vibrate. The board is gradually straightened through multiple sorting sections 525. When the board reaches the vertical section 524 from the sorting section 525, the position adjustment of the board is completed, and it continues to slide along the vertical section 524, with the board abutting against the sorting frame 521. Next, the sorting frame 521 continues to drive the plate to rotate. When the adjusting rod 81 rotates to the extrusion plate 821 and rotates along the extrusion plate 821, the extrusion plate 821 can push the adjusting rod 81 to drive the sliding part 722 to slide away from the fixed part 721. When the sliding part 722 slides, it stretches the elastic element 822. When the adjusting rod 81 rotates to the end of the extrusion plate 821 near the bending table 4, the drive component 102 is turned off, and the rotating block 71, connecting rod 72, and sorting frame 521 no longer rotate. At this time, the sorting frame 521 near the bending table 4 is set parallel to the bending table 4, and the entire... The rack 521 is adjacent to the bending table 4. Then the driver 532 works, the output shaft of the driver 532 extends, the driver 532 drives the push plate 531 to slide and push the plate. The plate slides along the rack 521 and slides out of the relief groove 523. Then the driver 532 continues to work, and drives the plate to slide onto the bending table 4 through the push plate 531. When the bending position of the plate corresponds to the top of the bending die 2, the driver 532 stops pushing the plate. Then the output shaft of the driver 532 retracts and the driver 532 drives the push plate 531 to reset. At the same time, the operator presses the sheet metal, and the drive mechanism drives the stamping die 3 to descend. The stamping die 3 cooperates with the bending die 2 to bend the sheet metal. After the sheet metal is bent, the drive mechanism drives the stamping die 3 to rise, and then the operator can take out the bent sheet metal. Next, the drive unit 102 operates, driving the rotating block 71, connecting rod 72, sorting frame 521 and adjusting rod 81 to continue rotating. When the adjusting rod 81 rotates away from the extrusion plate 821, the elastic element 822 releases its elastic restoring force, driving the sliding part 722 to slide closer to the fixed part 721, so that the sliding part 722 is reset. After the sorting frame 521 rotates 90° from the bending table 4, the sheet metal is placed on the sorting frame 521 for feeding. This process is repeated to realize the stamping and bending processing of multiple sheet metals.

[0044] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

The sorting component includes multiple sorting frames spaced apart on the mounting plate along the axial direction of the mounting plate and multiple sorting rods set on the sorting frames for neatly processing the four edges of the sheet metal. The end of the sorting frame facing the forming machine body has a clearance groove for the sheet metal to pass through. The sorting rod includes a vertical part set on the sorting frame and a sorting part set at the top of the vertical part for neatly processing the sheet metal. The sorting part is inclined away from the sorting frame in a vertically upward direction. The sheet metal is placed between the multiple sorting rods from the top of the multiple sorting rods and slides down along the multiple sorting rods, gradually being neatly processed. After the sheet metal reaches the pushing component, the neat processing is completed. The pushing component pushes the sheet metal horizontally and slides it onto the bending table for bending processing. The mounting plate is equipped with a connecting device, which includes a rotating block and a connecting rod that are rotatably fitted on the mounting plate along its axial direction. The connecting rod includes a fixed part connected to the rotating block and a sliding part that is slidably fitted on the fixed part along the radial direction of the mounting plate. The mounting plate is equipped with a vibration device and an adjustment device for adjusting the sliding part. The adjustment device includes an adjustment rod mounted on the sorting rack and vertically arranged, and an adjustment assembly for adjusting the adjustment rod. The adjustment assembly includes an extrusion plate mounted in the mounting plate and an elastic element fitted on the fixed part for adjusting the sliding part to slide closer to the fixed part. One end of the elastic element is connected to the fixed part, and the other end is connected to the sliding part. The extrusion plate is an arc-shaped plate, and one end is inclined away from the rotating block along the rotation direction of the rotating block. The bottom end of the adjustment rod is provided with an arc-shaped surface. When the adjustment rod rotates to the end of the extrusion plate close to the bending table, the sorting rack close to the bending table is parallel to and adjacent to the bending table. The fixed part slides vertically into the rotating block. The vibration device includes an elastic element 2 for driving the fixed part to slide vertically downward and a vibration plate disposed in the mounting plate. One end of the elastic element 2 is connected to the fixed part and the other end is connected to the rotating block. The vibration plate is provided with multiple extrusion arc surfaces for pushing the adjusting rod to rise vertically. The vibration plate is an arc-shaped plate with arc-shaped surfaces at both ends.
