Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a sheet metal bending machine. Background Technology

[0002] Sheet metal processing refers to the process of cutting, shaping, and splicing raw materials such as wood, metal, and plastic into sheet metal products of specific shapes and sizes, which are widely used in the construction, furniture, and decoration industries. During sheet metal processing, bending machines are sometimes used to bend the metal sheets.

[0003] During the bending process on a sheet metal bending machine, bending dies are typically changed according to different bending degrees and shapes. However, existing bending dies usually require specialized tools for disassembly and replacement, making the process inconvenient. Therefore, improving the ease of bending die replacement is a crucial issue that needs to be addressed in the design of sheet metal bending machines. Utility Model Content

[0004] This utility model provides a sheet metal bending machine to solve the problem of inconvenient disassembly and replacement of bending dies.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a sheet metal bending machine, including a sheet metal processing table, and further including: a support shell fixedly connected to the top side wall of the sheet metal processing table, an installation platform placed inside the support shell, and a lower bending mold fixedly connected to the top side wall of the installation platform;

[0007] A fixing and limiting structure is provided on the sheet metal processing table;

[0008] A pushing structure is provided, which is mounted on a fixed limiting structure. The movement of the fixed limiting structure drives the pushing structure to move.

[0009] Preferably, four support legs are fixedly connected to the bottom side wall of the plate processing table, and two sliding through grooves and a pushing through groove are opened on the side wall of the plate processing table. The two sliding through grooves and the pushing through groove are distributed on both sides of the support housing, and two grooves are opened on the side walls of both sides of the mounting table.

[0010] Preferably, two support frames are fixedly connected to the top side wall of the plate processing table, two hydraulic push rods are fixedly connected to the top side wall of the two support frames, and an upper bending mold is fixedly connected to the bottom of the two hydraulic push rods.

[0011] Preferably, the upper bending die and the lower bending die correspond to each other.

[0012] In this technical solution, the hydraulic push rod extends to push the upper bending die downward, pressing the sheet metal, and working with the lower bending die to bend the sheet metal.

[0013] Preferably, the fixing and limiting structure includes a fixing frame, a motor, a rotating rod, and a rotating circular plate. The fixing frame is fixedly connected to the bottom side wall of the plate processing table. The motor is fixedly connected to the side wall of the fixing frame. The rotating end of the motor is fixedly connected to the rotating rod. The other end of the rotating rod is rotatably connected to the bottom side wall of the plate processing table. The rotating circular plate is fixedly connected to the side wall of the rotating rod.

[0014] In this technical solution, the machine rotates clockwise, the motor drives the rotating rod to rotate, and the rotating rod drives the rotating disc to rotate clockwise.

[0015] Preferably, the fixed limiting structure includes a fixed limiting frame, a fixed plate, a connecting frame, a movable plate, and a connecting rod. The fixed limiting frame is slidably connected in a sliding groove and slidably connected to the side walls on both sides of the supporting housing. The fixed plate is fixedly connected to the side wall of the fixed limiting frame, and the fixed plate is located on the upper and lower sides of the plate processing table. The connecting frame is fixedly connected to the bottom side wall of the fixed limiting frame, and the other end of the connecting frame is fixedly connected to the movable plate. The movable plate is slidably connected to the bottom side wall of the plate processing table, and one end of the connecting rod is rotatably connected to the side wall of the movable plate. The other end of the connecting rod is rotatably connected to the side wall of the rotating circular plate.

[0016] In this technical solution, the rotating circular plate rotates, causing the connecting rod to move. The connecting rod pulls the moving plate to move, the moving plate causes the connecting frame and the fixed block to move, and the connecting frame causes the fixed limiting frame to move, so that the fixed limiting frame causes the supporting shell to move.

[0017] Preferably, the connecting frame is slidably connected to the side wall of the fixed frame, and the two ends of the connecting frame are respectively located on both sides of the fixed frame.

[0018] Preferably, the fixing and limiting frame cooperates with the grooves on both sides of the mounting platform.

[0019] In this technical solution, the fixing and limiting frame is inserted into the grooves on both sides of the mounting platform, and the vertical movement of the mounting platform is limited by the fixing and limiting frame.

[0020] Preferably, the pushing structure includes a first fixed block, a first pushing rod, a second pushing rod, and a second fixed block. The first fixed block is fixedly connected to the side wall of the movable plate. The first pushing rod is rotatably connected between the first fixed blocks. The other end of the first pushing rod is rotatably connected to two second pushing rods. The other ends of the two second pushing rods are rotatably connected to two second fixed blocks. The second fixed block is fixedly connected to the bottom side wall of the plate processing table.

[0021] In this technical solution, the movement of fixed block one will push push rod one and push rod two to rotate and arch upward.

[0022] Preferably, the first push rod and the second push rod are directly opposite the push through groove, and the sum of the widths of the two push rods is less than the width of the push through groove.

[0023] In this technical solution, the arched push rod one and push rod two can extend into the push through groove.

[0024] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0025] The positive and progressive effects of this utility model are as follows:

[0026] 1. The movement of the mounting platform in all directions is restricted by the supporting housing. The motor drives the rotating plate to rotate counterclockwise, which causes the fixed limiting frame to engage with the grooves on both sides of the mounting platform. The fixed limiting frame restricts the vertical movement of the mounting platform, thus fixing the mounting platform and facilitating better fixation of the lower bending mold.

[0027] 2. The clockwise rotation of the motor drives the rotating disc to rotate clockwise. The rotation of the disc moves the connecting frame and the first fixing block. The connecting frame moves the fixed limiting frame away from the supporting shell. When the disc rotates 45 degrees, the fixed limiting frame disengages from the groove on the mounting platform and no longer restricts the movement of the mounting platform. The movement of the first fixing block pushes the first and second push rods to rotate and arch upwards. When the fixed limiting frame disengages from the groove, the arched parts of the first and second push rods are exactly against the bottom of the mounting platform. The disc then rotates to 90 degrees, and the first and second push rods push the mounting platform to rise. The mounting platform then lifts the lower bending die, which facilitates the simultaneous movement of the fixed limiting frame and the lifting of the lower bending die by the pushing structure, making the replacement and disassembly of the lower bending die more convenient.

[0035] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0036] like Figure 1-5 As shown, the sheet metal bending machine includes a sheet metal processing table 1, and further includes: a support housing 3 fixedly connected to the top side wall of the sheet metal processing table 1, an installation platform 8 placed inside the support housing 3, and a lower bending die 4 fixedly connected to the top side wall of the installation platform 8.

[0037] A fixing and limiting structure 9 is disposed on the plate processing table 1;

[0038] A pushing structure 10 is provided on a fixed limiting structure 9. The movement of the fixed limiting structure 9 drives the pushing structure 10 to push.

[0039] Four support legs 2 are fixedly connected to the bottom side wall of the plate processing table 1. Two sliding through grooves 11 and pushing through grooves 12 are opened on the side wall of the plate processing table 1. The two sliding through grooves 11 and pushing through grooves 12 are distributed on both sides of the support housing 3. Two grooves are opened on the side walls of both sides of the mounting table 8.

[0040] Two support frames 5 are fixedly connected to the top side wall of the plate processing table 1, and two hydraulic push rods 6 are fixedly connected to the top side wall of the two support frames 5. An upper bending mold 7 is fixedly connected to the bottom of the two hydraulic push rods 6.

[0041] The upper bending die 7 and the lower bending die 4 correspond to each other.

[0042] The hydraulic push rod 6 extends to push the upper bending die 7 down, pressing the sheet metal, and working with the lower bending die 4 to bend the sheet metal.

[0043] The fixed limiting structure 9 includes a fixed frame 911, a motor 912, a rotating rod 913, and a rotating circular plate 914. The fixed frame 911 is fixedly connected to the bottom side wall of the plate processing table 1. The motor 912 is fixedly connected to the side wall of the fixed frame 911. The rotating end of the motor 912 is fixedly connected to the rotating rod 913. The other end of the rotating rod 913 is rotatably connected to the bottom side wall of the plate processing table 1. The rotating circular plate 914 is fixedly connected to the side wall of the rotating rod 913.

[0044] The motor 912 rotates clockwise, which drives the rotating rod 913 to rotate, and the rotating rod 913 drives the rotating circular plate 914 to rotate clockwise.

[0045] The fixed limiting structure 9 includes a fixed limiting frame 901, a fixed plate 902, a connecting frame 903, a movable plate 904, and a connecting rod 905. The fixed limiting frame 901 is slidably connected in the sliding through groove 11 and is slidably connected to the side walls on both sides of the supporting housing 3. The fixed plate 902 is fixedly connected to the side wall of the fixed limiting frame 901. The fixed plate 902 is located on the upper and lower sides of the plate processing table 1. The connecting frame 903 is fixedly connected to the bottom side wall of the fixed limiting frame 901. The other end of the connecting frame 903 is fixedly connected to the movable plate 904. The movable plate 904 is slidably connected to the bottom side wall of the plate processing table 1. One end of the connecting rod 905 is rotatably connected to the side wall of the movable plate 904. The other end of the connecting rod 905 is rotatably connected to the side wall of the rotating circular plate 914.

[0046] Rotating the circular plate 914 causes the connecting rod 905 to move, which in turn pulls the moving plate 904 to move. The moving plate 904 then moves the connecting frame 903 and the fixed block 1001. The connecting frame 903 then moves the fixed limiting frame 901, which in turn moves the supporting shell 3.

[0047] The connecting frame 903 is slidably connected to the side wall of the fixed frame 911, and the two ends of the connecting frame 903 are respectively located on both sides of the fixed frame 911.

[0048] The fixed limiting frame 901 cooperates with the grooves on both sides of the mounting platform 8.

[0049] The fixed limiting bracket 901 is inserted into the grooves on both sides of the mounting platform 8, and the up and down movement of the mounting platform 8 is limited by the fixed limiting bracket 901.

[0050] The pushing structure 10 includes a first fixed block 1001, a first pushing rod 1002, a second pushing rod 1003, and a second fixed block 1004. The first fixed block 1001 is fixedly connected to the side wall of the moving plate 904. The first pushing rod 1002 is rotatably connected between the first fixed blocks 1001. The other end of the first pushing rod 1002 is rotatably connected to two second pushing rods 1003. The other ends of the two second pushing rods 1003 are rotatably connected to two second fixed blocks 1004. The second fixed block 1004 is fixedly connected to the bottom side wall of the plate processing table 1.

[0051] When the fixed block 1001 moves, it will push the push rod 1002 and the push rod 2 1003 to rotate and arch upward.

[0052] The first push rod 1002 and the second push rod 1003 are directly opposite the push through groove 12, and the sum of the widths of the two push rods 1003 and the first push rod 1002 is less than the width of the push through groove 12.

[0053] This allows the arched push rod 1002 and push rod 2 1003 to extend into the push through groove 12.

[0054] In use, the electrical components mentioned in this application are all connected to an external power supply and control switch. When bending the sheet metal, the sheet metal is placed on the lower bending die 4, and the hydraulic push rod 6 extends to push the upper bending die 7 down, pressing the sheet metal, and working with the lower bending die 4 to bend the sheet metal.

[0055] When the lower bending die 4 needs to be replaced, the motor 912 rotates clockwise, which drives the rotating rod 913 to rotate. The rotating rod 913 drives the rotating circular plate 914 to rotate clockwise. The rotation of the rotating circular plate 914 drives the connecting rod 905 to move. The connecting rod 905 pulls the moving plate 904 to move. The moving plate 904 drives the connecting frame 903 and the fixing block 1001 to move. The connecting frame 903 drives the fixed limiting frame 901 to move, so that the fixed limiting frame 901 moves away from the supporting housing 3. When the rotating circular plate 914 rotates 45 degrees, the fixed limiting frame 901 disengages from the groove on the mounting platform 8 and no longer restricts the movement of the mounting platform 8.

[0056] When the fixed block 1001 moves with the moving plate 904, it will push the push rod 1002 and the push rod 2003 to rotate and arch upward. The connection between the push rod 1002 and the push rod 2003 arches and extends into the push through groove 12. When the fixed limiting frame 901 is disengaged from the groove, the arched part of the push rod 1002 and the push rod 2003 is exactly against the bottom of the mounting platform 8. The rotating circular plate 914 then rotates to 90 degrees, and the push rod 1002 and the push rod 2003 push the mounting platform 8 to rise. The mounting platform 8 then drives the lower bending mold 4 to be lifted. It is better to drive the push structure 10 to lift the lower bending mold 4 while the fixed limiting frame 901 moves, so that the replacement and disassembly of the lower bending mold 4 is more convenient.

[0057] After replacement, the mounting platform 8 below the new lower bending mold 4 is placed into the support housing 3. The support housing 3 restricts the movement of the mounting platform 8 in all directions. The motor 912 drives the rotating circular plate 914 to rotate 90 degrees counterclockwise, causing the fixed limiting frame 901 to re-engage into the grooves on both sides of the mounting platform 8. The fixed limiting frame 901 restricts the up and down movement of the mounting platform 8, thus fixing and restricting the mounting platform 8, thereby effectively fixing and restricting the lower bending mold 4.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
