Description

Technical Field

[0001] This invention relates to the field of bending equipment, and in particular to a bending mechanism that can be adjusted at multiple angles. Background Technology

[0002] In the steel production and processing, bending of sheet metal is a frequent operation. This bending process is usually carried out using a bending machine. During the process, the sheet metal is fixed on a special mold, and then external force is applied to the sheet metal to make the suspended part of the sheet metal conform to the mold, thereby completing the bending operation. However, the mold on the bending machine can usually only perform a bending operation at a fixed angle. If the same sheet metal needs to be processed for multiple bends, it needs to be transported to other bending machines for further bending. This undoubtedly reduces the efficiency of sheet metal bending operations and also increases the cost of purchasing additional bending machines.

[0003] Based on this, the present invention provides a bending mechanism that can be adjusted to multiple angles, so as to realize bending of sheet metal at multiple angles on the same bending mechanism, thereby improving the efficiency of sheet metal bending operation and reducing the purchase cost of bending machine. Summary of the Invention

[0004] Based on this, it is necessary to provide a bending mechanism that can be adjusted at multiple angles, including a frame, an installation platform on the frame, a cylindrical installation column vertically installed on the installation platform, the installation column being fixedly installed on the installation platform, an upright plate being fixedly installed on the upper surface of the installation column, the upright plate being installed along the front-back direction, the front end of the upright plate being semi-cylindrical and coaxial with the installation column; The mounting platform is also rotatably provided with a turntable, the rotation center axis of the turntable and the axis of the mounting column are located on the same vertical line, and the center of the turntable is provided with a receiving window corresponding to the mounting column, and the mounting column is located in the receiving window; The upper surface of the turntable is provided with a clamping part, which is located on the right side of the upright plate. The clamping part includes a first clamping plate and a second clamping plate arranged in front and behind. Both the first clamping plate and the second clamping plate are arranged in the left and right direction, and the front side wall of the first clamping plate is on the same plane as the front end of the upright plate. The mounting platform is also provided with an extrusion block corresponding to the upright plate. The extrusion block is located on the left side of the upright plate, and there is a gap between the right side of the extrusion block and the upright plate. The right sidewall of the extrusion block is parallel to the upright plate. The mounting platform is also provided with a driving mechanism corresponding to the extrusion block. The driving mechanism is drivenly connected to the extrusion block to drive the extrusion block to move back and forth. It also includes a locking mechanism, which includes a positioning plate fixedly mounted on the mounting platform and a locking device for fixing the relative position of the turntable and the positioning plate.

[0005] This invention is used for bending metal sheets requiring multiple bends. In this invention, the sheet is clamped between the first and second clamping plates of the clamping part, thus fixing the sheet. The sheet then extends from the front end of the upright plate to its left side. A driving mechanism then moves the pressing block backward, pressing the sheet against the left sidewall of the upright plate, completing the bending. The bending angle is determined by the angle between the upright plate and the clamping part. Therefore, the bending angle can be adjusted by rotating the turntable relative to the mounting column to change the angle between the clamping part and the upright plate. This invention allows for bending at multiple angles, enabling the processing of multiple bent structures on a single machine without transferring the sheet to another bending machine, effectively improving the efficiency of sheet bending and reducing the number of bending machines required, thereby lowering production costs. After adjusting the angle between the clamping part and the upright plate by rotating the turntable, the sheet is fixed using a locking device.

[0006] Furthermore, the positioning plate is located on the right side of the turntable, and the locking device includes a plurality of first positioning seats mounted on the positioning plate and a second positioning seat fixedly disposed on the turntable; the first positioning seat includes a positioning block mounted on the positioning plate, and the upper surface of the positioning block is provided with a receiving groove, which is disposed through the positioning block along the radial direction of the mounting post; the second positioning seat is located on the right side of the turntable, and the second positioning seat includes a mounting seat fixedly disposed on the turntable, and a connecting rod is disposed on the mounting seat, one end of the connecting rod being rotatably disposed on the mounting seat through a rotating shaft, and the rotating shaft being disposed perpendicular to the radial direction of the mounting post, the connecting rod being disposed along the radial direction of the mounting post, and the diameter of the connecting rod being the same as the width of the receiving groove.

[0007] In this invention, by rotating the connecting rod on the mounting base into the receiving groove embedded in the positioning block, the corresponding mounting base and positioning block can be fixed to each other, that is, the turntable and positioning block can be fixed to each other, and the angle between the upright plate and the clamping part is fixed.

[0008] In this invention, since the receiving groove and the connecting rod are both arranged along the radial direction of the mounting column, during the rotation of the turntable, as long as the connecting rod aligns with the receiving groove on any positioning block, the connecting rod can be embedded into the corresponding receiving groove, thus fixing the turntable and the positioning plate. The position of the positioning block needs to be preset according to the bending angle of the sheet material. By embedding the connecting rod on the mounting base into different positioning blocks, multiple bending angles of the sheet material can be adjusted.

[0009] Furthermore, the positioning plate is provided with an arc-shaped mounting part, the center of which is located at the rotation center axis of the turntable, and the positioning block is detachably mounted on the mounting part.

[0010] In this invention, the positioning block is detachably mounted on the mounting part. Therefore, the mounting position of the positioning block on the mounting part can be changed. Changing the mounting position of the positioning block can change the angle between the upright plate and the clamping plate after the turntable and the positioning plate are fixed together, that is, change the bending angle of the plate. It can be seen that the bending mechanism of the invention can be applied to the bending processing of plates at more angles.

[0011] Furthermore, the mounting part is a first mounting groove formed on the positioning plate, extending vertically through the positioning plate. A limiting post is fixedly provided at the bottom of the positioning block corresponding to the first mounting groove. The lower end of the limiting post extends downward out of the first mounting groove, and a support rod is fixedly connected to the lower end of the limiting post. The support rod is arranged along the radial direction of the mounting post, and a mounting ring is fixedly provided at the end of the support rod facing the mounting post. The mounting ring is sleeved on the mounting post and rotatably connected to the mounting post through a bearing. The portion of the limiting post above the support rod is also provided with an external thread forming a threaded section. A nut is sleeved on the threaded section, and the nut abuts against the lower surface of the positioning plate.

[0012] In this invention, the positioning block is fixedly connected to the positioning plate by a nut that abuts against the positioning plate. The first mounting groove is arc-shaped and its center is located on the axis of the mounting column. By rotating the positioning block relative to the mounting column, the position of the positioning block relative to the first mounting groove can be adjusted, and the receiving groove on the positioning block is always arranged along the radial direction of the mounting column, thereby ensuring that the connecting rod on the second positioning seat can be smoothly embedded into the receiving groove on the positioning block.

[0013] Preferably, the positioning plate is mounted on the installation platform by a bracket, so that there is operating space below the positioning plate, which facilitates the operation of the nut that is pressed against the positioning plate, thereby facilitating the adjustment of the position of the positioning block relative to the positioning plate.

[0014] Furthermore, the turntable has a first mounting groove group corresponding to the second clamping plate. The first mounting groove group includes two second mounting grooves arranged along the front-back direction. The second mounting grooves are arranged vertically through the turntable. The second clamping plate has a first mounting hole corresponding to the second mounting groove, which is vertically through the second clamping plate. The second clamping plate is mounted to the turntable by bolts that pass through both the first mounting hole and the second mounting groove.

[0015] In this invention, the bolt structure passing through the first mounting hole and the second mounting groove can lock the second clamping plate onto the turntable, thereby fixing the second clamping plate and the positioning plate. Preferably, the turntable is rotatably mounted on the mounting column via a bearing structure, so that there is a certain operating space below it, which facilitates the operation of the bolt structure that locks the second clamping plate and the turntable, thereby facilitating the adjustment of the position of the second clamping plate relative to the turntable. At the same time, a support structure for supporting the turntable can also be provided on the mounting platform corresponding to the bottom of the turntable, such as a support column with a ball bearing structure at the top, to prevent the turntable from deflecting during operation.

[0016] In this invention, the distance between the first clamping plate and the second clamping plate bracket can be adjusted by adjusting the fixed position of the second clamping plate relative to the second mounting groove, thereby enabling the clamping part to clamp plates of different thicknesses and improving the adaptability of the bending mechanism of this invention.

[0017] Furthermore, a mounting plate for mounting the drive mechanism is fixedly provided on the mounting platform corresponding to the drive mechanism, and the mounting plate is fixedly provided at the front end of the mounting platform; the drive mechanism includes a base plate and a hydraulic cylinder fixedly provided on the base plate, and the piston rod of the hydraulic cylinder is fixedly connected to the extrusion block; a second mounting groove group is provided on the mounting plate corresponding to the base plate, the second mounting groove group includes two third mounting grooves arranged in the left-right direction, the third mounting grooves are arranged vertically through the mounting plate, and the base plate is provided with at least two second mounting holes corresponding to each third mounting groove, and the base plate is mounted to the mounting plate by bolts passing through the second mounting holes and the third mounting grooves simultaneously.

[0018] In this invention, the base plate is fixed to the mounting plate by bolts, thereby fixing the drive mechanism to the mounting plate. The left and right positions of the drive mechanism can be adjusted by adjusting the left and right positions of the bolts in the third mounting groove, thereby adjusting the left and right positions of the extrusion block and the width of the gap between the extrusion block and the upright plate. This allows the extrusion block to be used for extruding plates of different thicknesses, and to extrude plates of different thicknesses to fit against the upright plate, thus effectively improving the applicability of this invention.

[0019] Furthermore, a support frame is also provided on the installation platform corresponding to the upright plate, and the portion of the upright plate extending out of the turntable is fixedly connected to the support frame.

[0020] In this invention, the support frame fixedly connected to the upright plate is used to support the upright plate, thereby improving the structural strength of the upright plate and preventing the upright plate from bending during the bending process of the plate.

[0021] Furthermore, the upper surface of the turntable and the upper surface of the mounting column are located on the same horizontal plane.

[0022] In this invention, the upper surface of the turntable and the upper surface of the mounting column are located on the same horizontal plane, which allows the upper surfaces of the turntable and the mounting column to jointly support the plate to be bent, so that the plate can complete its bending process more smoothly.

[0023] The principles and effects of the present invention will be further explained below with reference to the above technical solutions and accompanying drawings: This invention is used for bending metal sheets requiring multiple bends. In this invention, the sheet is clamped and fixed by inserting it between the first and second clamping plates of the clamping part. The sheet then extends from the front end of the upright plate to the left side of the upright plate. A driving mechanism then drives the pressing block to move backward, pressing the sheet against the left side wall of the upright plate, thus completing the bending. The bending angle is determined by the angle between the upright plate and the clamping part. Therefore, by rotating the turntable relative to the mounting column, the angle between the clamping part and the upright plate can be adjusted, thereby adjusting the bending angle of the sheet. This invention enables bending of sheet metal at multiple angles, allowing multiple bent structures to be processed on a single machine without transferring the sheet to another bending machine for further processing. This effectively improves the efficiency of sheet metal bending and reduces the number of bending machines required, thus lowering production costs. Attached Figure Description

Detailed Implementation

[0027] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments: like Figure 1-4 A bending mechanism adjustable at multiple angles includes a frame (not shown in the figure), a mounting platform 1 on the frame, a cylindrical mounting column 2 vertically mounted on the mounting platform 1, the mounting column 2 fixedly mounted on the mounting platform 1, a vertical plate 21 fixedly mounted on the upper surface of the mounting column 2, the vertical plate 21 being arranged along the front-rear direction, the front end of the vertical plate 21 being semi-cylindrical and coaxial with the mounting column 2; a turntable 3 rotatably mounted on the mounting platform 1, the rotation center axis of the turntable 3 being on the same vertical line as the axis of the mounting column 2, and the center of the turntable 3 having an opening corresponding to the mounting column 2, the mounting column 2 being located within the opening; a clamping part is provided on the upper surface of the turntable 3, the clamping part being located on the right side of the vertical plate 21, the clamping part including a first clamp arranged front and rear. The mounting platform 1 includes a first clamping plate 311 and a second clamping plate 312, both arranged along the left-right direction. The front side wall of the first clamping plate 311 is on the same plane as the front end of the upright plate 21. A pressing block 5 is also provided on the mounting platform 1 corresponding to the upright plate 21. The pressing block 5 is located on the left side of the upright plate 21, and there is a gap between the right side of the pressing block 5 and the upright plate 21. The right side wall of the pressing block 5 is parallel to the upright plate 21. A driving mechanism is also provided on the mounting platform 1 corresponding to the pressing block 5. The driving mechanism is drivenly connected to the pressing block 5 to drive the pressing block 5 to move back and forth. The mounting platform 1 also includes a locking mechanism, which includes a positioning plate 4 fixedly arranged on the mounting platform 1 and a locking device for fixing the relative position of the turntable 3 and the positioning plate 4.

[0028] This invention is used for bending metal sheets 8 that require multiple bends. In this invention, the sheet 8 is clamped between the first clamping plate 311 and the second clamping plate 312 of the clamping part, thus fixing the sheet 8. At this time, the sheet 8 extends past the front end of the upright plate 21 to the left side of the upright plate 21. Then, the extrusion block 5 is driven backward by the driving mechanism to extrude the sheet 8 until it adheres to the left side wall of the upright plate 21. This completes the bending of the sheet 8. The bending angle of the sheet 8 is determined by the upright plate... The angle between the clamping part and the clamping part is determined by the angle between the clamping part and the upright plate 21. Therefore, by rotating the turntable 3 relative to the mounting column 2 to adjust the angle between the clamping part and the upright plate 21, the bending angle of the plate 8 can be adjusted. Thus, this invention can achieve bending of the plate 8 at multiple angles, allowing multiple bent structures of the plate 8 to be processed on a single machine without having to transport the plate 8 to another bending machine for further processing. This effectively improves the efficiency of bending the plate 8 and reduces the number of bending machines required during processing, thereby lowering production costs. In this invention, after adjusting the angle between the clamping part and the upright plate 21 by rotating the turntable 3, it can be fixed by a locking device.

[0029] In one embodiment, the positioning plate 4 is located on the right side of the turntable 3. The locking device includes a plurality of first positioning seats mounted on the positioning plate 4 and a second positioning seat fixedly mounted on the turntable 3. The first positioning seat includes a positioning block 42 mounted on the positioning plate 4. The upper surface of the positioning block 42 is provided with a receiving groove 421, which is provided through the positioning block 42 along the radial direction of the mounting post 2. The second positioning seat is located on the right side of the turntable 3. The second positioning seat includes a mounting seat 331 fixedly mounted on the turntable 3. A connecting rod 332 is provided on the mounting seat 331. One end of the connecting rod 332 is rotatably mounted on the mounting seat 331 through a rotating shaft, which is arranged perpendicular to the radial direction of the mounting post 2. The connecting rod 332 is arranged along the radial direction of the mounting post 2, and the diameter of the connecting rod 332 is the same as the width of the receiving groove 421.

[0030] In this embodiment, by rotating the connecting rod 332 on the mounting base 331 into the receiving groove 421 embedded in the positioning block 42, the corresponding mounting base 331 and positioning block 42 can be fixed to each other, that is, the turntable 3 and positioning block 42 can be fixed to each other, and the angle between the upright plate 21 and the clamping part is fixed.

[0031] In this embodiment, since the receiving groove 421 is arranged along the radial direction of the mounting post 2, and the connecting rod 332 is also arranged along the radial direction of the mounting post 2, during the rotation of the turntable 3, as long as the connecting rod 332 aligns with the receiving groove 421 on any positioning block 42, the connecting rod 332 can be embedded into the corresponding receiving groove 421, thereby fixing the turntable 3 to the positioning plate 4. The position of the positioning block 42 needs to be preset according to the bending angle of the plate 8. By embedding the connecting rod 332 on the mounting base 331 into different positioning blocks 42, multiple bending angles of the plate 8 can be adjusted.

[0032] In one embodiment, the positioning plate 4 is provided with an arc-shaped mounting part, the center of which is located at the rotation center axis of the turntable 3, and the positioning block 42 is detachably disposed on the mounting part.

[0033] In this embodiment, the positioning block 42 is detachably mounted on the mounting part. Therefore, the mounting position of the positioning block 42 on the mounting part can be changed. Changing the mounting position of the positioning block 42 can change the angle between the upright plate 21 and the clamping plate after the turntable 3 and the positioning plate 4 are fixed together, that is, change the bending angle of the plate 8. It can be seen that the bending mechanism of the invention can be applied to bending processing of plate 8 at more angles.

[0034] In one embodiment, the mounting part is a first mounting groove 41 that extends vertically through the positioning plate 4. A limiting post 422 is fixedly provided at the bottom of the positioning block 42 corresponding to the first mounting groove 41. The lower end of the limiting post 422 extends downward out of the first mounting groove 41, and a support rod 424 is fixedly connected to the lower end of the limiting post 422. The support rod 424 is arranged along the radial direction of the mounting post 2, and a mounting ring 425 is fixedly provided at one end of the support rod 424 facing the mounting post 2. The mounting ring 425 is sleeved on the mounting post 2 and rotatably connected to the mounting post 2 through a bearing. The portion of the limiting post 422 above the support rod 424 is also provided with an external thread forming a threaded section. A nut 423 is sleeved on the threaded section, and the nut 423 abuts against the lower surface of the positioning plate 4.

[0035] In this embodiment, the positioning block 42 is fixedly connected to the positioning plate 4 by a nut 423 that abuts against the positioning plate 4. The first mounting groove 41 is arc-shaped and its center is located on the axis of the mounting post 2. By rotating the positioning block 42 relative to the mounting post 2, the position of the positioning block 42 relative to the first mounting groove 41 can be adjusted, and the receiving groove 421 on the positioning block 42 is always arranged along the radial direction of the mounting post 2, thereby ensuring that the connecting rod 332 on the second positioning seat can be smoothly embedded into the receiving groove 421 on the positioning block 42.

[0036] Preferably, the positioning plate 4 is mounted on the mounting platform 1 by a bracket, so that there is operating space below the positioning plate 4, which facilitates the operation of the nut 423 that is pressed against the positioning plate 4, thereby facilitating the adjustment of the position of the positioning block 42 relative to the positioning plate 4.

[0037] In one embodiment, the turntable 3 has a first set of mounting grooves 41 corresponding to the second clamping plate 312. The first set of mounting grooves 41 includes two second mounting grooves 321 arranged along the front-back direction. The second mounting grooves 321 are arranged vertically through the turntable 3. The second clamping plate 312 has a first mounting hole corresponding to the second mounting groove 321, which is vertically through the second clamping plate 312. The second clamping plate 312 is mounted on the turntable 3 by bolts that pass through both the first mounting hole and the second mounting groove 321.

[0038] In this embodiment, the bolt structure passing through the first mounting hole and the second mounting groove 321 can lock the second clamping plate 312 onto the turntable 3, thereby fixing the second clamping plate 312 to the positioning plate 4. Preferably, the turntable 3 is rotatably mounted on the mounting column 2 through a bearing structure, so that there is a certain operating space below it, which facilitates the operation of the bolt structure that locks the second clamping plate 312 and the turntable 3, thereby facilitating the adjustment of the position of the second clamping plate 312 relative to the turntable 3. At the same time, a support structure for supporting the turntable 3 can also be provided on the mounting platform 1 corresponding to the bottom of the turntable 3, such as a support column with a ball bearing structure at the top, to prevent the turntable 3 from deflecting during operation.

[0039] In this embodiment, the distance between the first clamping plate 311 and the second clamping plate 312 bracket can be adjusted by adjusting the fixed position of the second clamping plate 312 relative to the second mounting groove 321, thereby enabling the clamping part to perform clamping operations on plates 8 of different thicknesses and improving the adaptability of the bending mechanism of the present invention.

[0040] In one embodiment, a mounting plate 7 for mounting the drive mechanism is fixedly disposed on the mounting platform 1 corresponding to the drive mechanism, and the mounting plate 7 is fixedly disposed at the front end of the mounting platform 1; the drive mechanism includes a base plate 61 and a hydraulic cylinder 62 fixedly disposed on the base plate 61, and the piston rod 621 of the hydraulic cylinder 62 is fixedly connected to the extrusion block 5; a second set of mounting grooves 321 is provided on the mounting plate 7 corresponding to the base plate 61, the second set of mounting grooves 321 includes two third mounting grooves 71 arranged in the left-right direction, the third mounting grooves 71 are disposed vertically through the mounting plate 7, and the base plate 61 is provided with at least two second mounting holes corresponding to each third mounting groove 71, and the base plate 61 is mounted to the mounting plate 7 by bolts passing through the second mounting holes and the third mounting grooves 71 simultaneously.

[0041] In this embodiment, the base plate 61 is fixed to the mounting plate 7 by bolts, thereby fixing the drive mechanism to the mounting plate 7. The left and right positions of the drive mechanism can be adjusted by adjusting the left and right positions of the bolts in the third mounting groove 71, thereby adjusting the left and right positions of the extrusion block 5, and thus adjusting the width of the gap between the extrusion block 5 and the upright plate 21. This allows the extrusion block 5 to be used for extruding plates 8 of different thicknesses, and to extrude plates 8 of different thicknesses to fit against the upright plate 21, which can effectively improve the applicability of the present invention.

[0042] In one embodiment, a support frame is also provided on the installation platform 1 corresponding to the upright plate 21, and the portion of the upright plate 21 extending out of the turntable 3 is fixedly connected to the support frame.

[0043] In this embodiment, the support frame fixedly connected to the upright plate 21 is used to support the upright plate 21, thereby improving the structural strength of the upright plate 21 and preventing the upright plate 21 from bending during the bending process of the plate 8.

[0044] In one embodiment, the upper surface of the turntable 3 and the upper surface of the mounting post 2 are located on the same horizontal plane.

[0045] In this embodiment, the upper surface of the turntable 3 and the upper surface of the mounting column 2 are located on the same horizontal plane, which allows the upper surfaces of the turntable 3 and the mounting column 2 to jointly support the plate 8 to be bent, so that the plate 8 can complete its bending process more smoothly.

[0046] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
