It is simple to operate, convenient to use, and improves disassembly efficiency.

[0036] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a sheet metal bending machine for automobile production in one embodiment of the present invention.

[0037] This utility model provides a sheet metal bending machine for automobile production, including a frame 1, a lower die 2, and an upper die assembly 3; the lower die 2 is disposed on the frame 1; the upper die assembly 3 includes an upper die base 31, an upper die 32, a connector 33, and a drive mechanism 34. The upper die base 31 is movably mounted on the frame 1 in the vertical direction. The upper die base 31 has a slot 311 with an opening facing the lower die.

The drive mechanism 34 is connected to the connector 33 and is used to drive the connector 33 to extend into or retract from the insertion hole.

[0038] In this embodiment, please refer to Figure 2 , Figure 3 and Figure 5The upper mold 32 is moved vertically by the upper mold base 31. The upper mold base 31 corresponds to the lower mold 2 in the vertical direction. The upper mold 32 and the lower mold 2 are used to bend the sheet metal. The upper mold base 31 and the upper mold 32 are connected by a plug-in joint. The plug-in member 33 can be inserted into the plug hole to fix the upper mold 32. The driving mechanism 34 can drive the plug-in member 33 to move. In actual use, when the upper mold 32 needs to be replaced, the driving mechanism 34 drives the plug-in member 33 to exit the plug hole, so that the upper mold 32 can be taken out of the slot 311 for replacement. The operation is simple and convenient, and the disassembly efficiency is improved.

[0039] In this embodiment, the slot 311 is adapted to the upper mold 32, thereby limiting the upper mold 32 circumferentially through the slot 311.

[0040] In this embodiment, please refer to Figure 3 and Figure 5 The frame 1 is provided with a worktable, the worktable is provided with a stand, the upper mold base 31 is slidably installed on the stand in the vertical direction, and the lower mold 2 is provided on the worktable.

[0041] In some embodiments, please refer to Figure 3 and Figure 5 The slot 311 has a mounting cavity 312 on one side, and the plug-in 33 is slidably mounted in the mounting cavity 312. The slot 311 has a positioning hole 313 on the other side, and the positioning hole 313 corresponds to the plug-in 33 so that when the plug-in 33 moves toward the upper mold 32, the plug-in 33 passes through the insertion hole and extends into the positioning hole 313.

[0042] In this embodiment, the connector 33 is used to fix the upper mold 32. To improve the fixing strength, the front side of the slot 311 is provided with a mounting cavity 312, and the rear side of the slot 311 is provided with a positioning hole 313 corresponding to the mounting cavity 312. The connector 33 is slidably installed in the mounting cavity 312 in the front-back direction. When the upper mold 32 is inserted into the slot 311, the positioning hole 313, the insertion hole, and the connector 33 correspond to each other. When the driving mechanism 34 drives the connector 33 to move backward, the connector 33 can pass through the insertion hole and extend into the positioning hole 313. This arrangement helps to improve the installation strength of the upper mold 32.

[0043] In some embodiments, please refer to Figure 2 and Figure 3The connector 33 includes a connecting plate 331, a plurality of plug-in pins 332, and a plug-in plate 333. The connecting plate 331 is slidably mounted on the upper mold base 31 in the front-back direction. The plurality of plug-in pins 332 are spaced apart on the connecting plate 331 in the left-right direction. The plug-in plate 333 is located below the connecting plate 331 and is slidably mounted on the upper mold base 31. The driving mechanism 34 is connected to the connecting plate 331 and the plug-in plate 333. Correspondingly, the insertion hole includes a plurality of round holes 321 and elongated holes 322. The round holes 321 are adapted to the plug-in pins 332, and the elongated holes 322 are adapted to the plug-in plate 333.

[0044] In this embodiment, the connecting plate 331 is slidably installed in the mounting cavity 312 along the front-back direction. The plug-in post 332 is installed on the rear side of the connecting plate 331. Multiple plug-in posts 332 are arranged at intervals along the left-right direction. The plug-in post 332 is adapted to the circular hole 321, and the multiple plug-in posts 332 correspond one-to-one with the multiple circular holes 321. The plug-in plate 333 is slidably installed in the mounting cavity 312 and is located below the connecting plate 331. The plug-in plate 333 is adapted to the elongated hole 322, and the elongated hole 322 corresponds to the plug-in plate 333. When the driving mechanism 34 drives the connecting plate 331 and the plug-in plate 333 to move backward, the plug-in post 332 can extend into the corresponding circular hole 321, and the plug-in plate 333 can extend into the elongated hole 322, thereby further improving the installation strength.

[0045] In this embodiment, multiple positioning holes 313 are provided, and each of the multiple positioning holes 313 corresponds to a multiple of the insertion pins 332. The insertion pins 332 can extend into the corresponding positioning holes 313.

[0046] In some embodiments, please refer to Figures 3 to 5 The driving mechanism 34 includes two mounting blocks 341 and a driving assembly. The two mounting blocks 341 are slidably mounted on the upper mold base 31 in the left and right direction. The two mounting blocks 341 are wedge-shapedly engaged with the connecting plate 331 and the plug-in plate 333, respectively. The driving assembly is connected to the two mounting blocks 341 to drive the two mounting blocks 341 to move.

[0047] In this embodiment, the upper mold 32 has a long and thin plate-like structure, meaning its lateral length is much greater than its longitudinal thickness. Correspondingly, the upper mold base 31 is also elongated in the lateral direction. The connecting plate 331 and the plug-in plate 333 are movable in the longitudinal direction. In order to minimize the longitudinal thickness of the upper mold base 31 while ensuring the movable installation of the connecting plate 331 and the plug-in plate 333, two mounting blocks 341 corresponding to the plug-in plate 333 and the connecting plate 331 are provided. The mounting blocks 341 are slidably installed in the mounting cavity 312 in the lateral direction. The two mounting blocks 341 are wedge-shaped with the connecting plate 331 and the plug-in plate 333, respectively. By utilizing the wedge-shaped engagement between them, the lateral movement of the mounting blocks 341 can be converted into the longitudinal movement of the connecting plate 331 and the plug-in plate 333. This arrangement helps to reduce the thickness of the upper mold base 31, thereby reducing the volume of the upper mold base 31.

[0048] In some embodiments, please refer to Figures 3 to 5 The mounting block 341 has a threaded hole; the drive assembly includes a lead screw 342 and a motor 343. The lead screw 342 is rotatably mounted on the upper mold base 31 along an upward axis. Both mounting blocks 341 are threadedly engaged with the lead screw 342. The main shaft of the motor 343 is connected to one end of the lead screw 342.

[0049] The manner in which the mounting block 341 is driven to move in the left and right directions is not limited.

[0050] In this embodiment, the lead screw 342 is rotatably mounted in the mounting cavity 312 along an upward axis. The lead screw 342 is threadedly engaged with the mounting block 341, thereby driving the two mounting blocks 341 to move by rotating the lead screw 342.

[0051] In another embodiment, the drive component is a cylinder or a hydraulic cylinder, and the push rod of the cylinder or the hydraulic cylinder is connected to the two mounting blocks 341, thereby driving the mounting blocks 341 to move.

[0052] In some embodiments, please refer to Figure 4 The connecting plate 331 is provided with a first wedge block 335; one of the mounting blocks 341 is provided with a second wedge block 3411, and the second wedge block 3411 is wedge-shapedly engaged with the first wedge block 335.

[0053] In this embodiment, the wedge-shaped surface of the first wedge block 335 is disposed facing the wedge-shaped surface of the second wedge block 3411, and the wedge-shaped surfaces of the two abut against each other. By utilizing the wedge-shaped cooperation between the second wedge block 3411 and the first wedge block 335, the movement of the mounting block 341 in the front-back direction is converted into the movement of the connecting plate 331 in the front-back direction.

[0054] In this embodiment, please refer to Figure 5 and Figure 6 The plug plate 333 is provided with a connecting post 334, and the other mounting block 341 is provided with a sloping groove 3412. The sloping groove 3412 is inclined in the horizontal direction, and the connecting post 334 is located in the sloping groove 3412.

[0055] In some embodiments, please refer to Figure 4 The upper mold assembly 3 further includes an elastic element 35, which connects the connecting plate 331 and the upper mold base 31. The elastic element 35 is used to drive the connecting plate 331 to move away from the upper mold 32.

[0056] In this embodiment, in order to ensure that the connecting plate 331 can return to its initial position, an elastic element 35 is provided between the connecting plate 331 and the side wall of the receiving cavity. When the connecting plate 331 moves backward, it can compress the elastic element 35. When the mounting block 341 returns to its initial position, the elastic element 35 can drive the connecting plate 331 to move forward and return to its initial position.

[0057] In some embodiments, please refer to Figure 1 and Figure 7 The automobile production sheet metal bending machine also includes two fixing components 4, which are located on the frame 1 and on the left and right sides of the lower die 2. The fixing components 4 are used to fix the sheet metal.

[0058] In this embodiment, to prevent the sheet material from shifting during bending, a fixing component 4 is also installed on the worktable. The two fixing components 4 are located on the left and right sides of the lower mold 2. The fixing components 4 can fix the sheet material on the worktable, thereby preventing the sheet material from shifting during bending.

[0059] In some embodiments, please refer to Figure 7 The fixing component 4 includes a mounting base 41, a pressure rod 42, and a driving component. The mounting base 41 is disposed on the frame 1 and located beside the lower mold 2. The middle part of the pressure rod 42 is rotatably mounted on the mounting base 41. The driving component is connected to the other end of the pressure rod 42 to drive the other end of the pressure rod 42 to move up and down. When the other end of the pressure rod 42 moves downward, the pressure rod 42 is used to press the plate.

[0060] In this embodiment, the mounting base 41 is mounted on the workbench, and the middle part of the pressure rod 42 is rotatably mounted on the upper side of the mounting base 41 along the left-right upward axis. The front end of the pressure rod 42 is a connecting end, which is used to connect with the driving component. The rear end of the pressure rod 42 is a clamping end, which is used to clamp the plate. In specific use, the driving component drives the connecting end to move upward, and correspondingly, the clamping end moves downward to press the plate onto the workbench to prevent it from shifting. After bending is completed, the driving component drives the connecting end to move downward, so that the clamping end moves upward to release the plate.

[0061] Specifically, the driving component includes a third wedge block 43 and a driving cylinder 44. The third wedge block 43 is movably mounted on the mounting base 41 in the front-rear direction and is located in front of the pressure rod 42. The upper side of the third wedge block 43 is provided with an abutment surface, which is gradually inclined downward from front to back. The abutment plate abuts against the lower side of the connecting end. The driving cylinder 44 is connected to the third wedge block 43 to drive the third wedge block 43 to move in the front-rear direction. When the third wedge block 43 moves backward, it drives the connecting end to move upward. When the third wedge block 43 moves forward, the connecting end moves downward under its own gravity.

[0062] Furthermore, the connecting end is also provided with a roller, which abuts against the contact surface.

[0063] In some embodiments, the mounting base 41 is movably disposed in the front-back and left-right directions so that the mounting base 41 is adjustable in the front-back and left-right upward positions.

[0064] In this embodiment, the fixing component 4 further includes a first base 45 and a second base 46. The first base 45 is mounted on the frame 1, and the second base 46 is slidably mounted on the first base 45 in the left-right direction. The mounting seat 41 is slidably mounted on the second base 46 in the front-back direction. The second base 46 can drive the mounting seat 41 to move in the left-right direction, thereby adjusting the left-right upward position of the mounting seat 41. The mounting seat 41 can also move in the front-back direction, thereby adjusting the front-back upward position of the mounting seat 41. This arrangement can adapt to plates of different lengths and specifications, expanding the applicability of the device.

[0065] To better understand this utility model, the following is combined with... Figures 1 to 7 The technical solution of this utility model is described in detail below:

[0066] In practical use, first, adjust the position of the mounting base 41 so that the fixing component 4 is adapted to the plate to be bent. Then, the driving component drives the pressure rod 42 to move and press the plate tightly. Next, select a suitable upper die 32 and insert the upper end of the upper die 32 into the slot 311. At this time, the round hole 321, the positioning hole 313 and the insertion post 332 correspond to each other, and the insertion plate 333 and the elongated hole 322 correspond to each other. The motor 343 drives the lead screw 342 to rotate, which in turn drives the two mounting blocks 341 to move. The two mounting blocks 341 wedge with the first wedge block 335 and the insertion plate 333, thereby driving the connecting plate 331 and the insertion plate 333 to move backward until the insertion post 332 passes through the round hole 321 and extends into the positioning hole 313, and the insertion plate 333 extends into the elongated hole 322, thereby completing the installation and fixing of the upper die 32, and the bending of the plate can then be performed.
