Description

Technical Field

[0001] The utility model relates to the field of plate processing, in particular to a plate bending device. Background Art

[0002] A plate bending device is a mechanical device specially used for folding and bending flat plates. This device is widely used in many industries, such as construction, electrical appliances and electricity, automobile manufacturing, aerospace, and machinery manufacturing.

[0003] Sheet metal bending devices use a specific mechanical structure, such as a press brake, to apply pressure to the metal sheet. Under the action of pressure, the metal sheet undergoes a transition from elastic deformation to plastic deformation, ultimately achieving the desired bending effect. In this process, the upper die (also called the punch or ram) and the lower die (also called the die or mold) of the press brake play a key role, together determining the angle, shape, and accuracy of the bend.

[0004] Existing plate bending devices generally bend plates by applying pressure to the plates. During use and observation, it was found that when the plate area is large during transportation before bending, its edges tend to sag, causing the entire plate to deform, thereby affecting the bending work.

[0005] Therefore, a plate bending device is proposed to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Specific examples are given below.

[0026] like Figures 1 to 5 As shown, a plate bending device described in an embodiment of the present invention includes an operating table 1; a linear motor 11 is fixedly connected to the middle of the operating table 1; a motor 12 is fixedly connected to the output end of the linear motor 11; a receiving platform 13 is fixedly connected to the output end of the motor 12; a plurality of first support platforms 14 are fixedly connected to the top of the receiving platform 13; a plurality of first spring telescopic rods 15 are symmetrically hinged on the side walls of the receiving platform 13; a connecting block 16 is fixedly connected to the end of the first spring telescopic rod 15; a second support platform 17 is fixedly connected to the connecting block 16, and a hydraulic component 18 is fixedly connected to the top of the operating table 1; when working, the plate is placed on the top of the first support platform 14, and then the linear motor 11 is turned on. When the linear motor 11 moves to the specified position, the hydraulic component 18 The plate is bent. When the bending work is completed, the motor 12 is turned on. The rotation of the motor 12 drives the receiving platform 13 to rotate together. When it rotates to the specified position, the hydraulic component 18 bends the other side of the plate. When the plate is too large, the edge of the plate will sag. At this time, the edge of the plate contacts the second support 17. When the edge of the plate and the second support 17 contact, the second support 17 supports the edge of the plate under the action of the first spring telescopic rod 15. The first spring telescopic rod 15 is hinged on the side wall of the receiving platform 13, and a connecting block 16 is fixed to the end of the first spring telescopic rod 15. The second support 17 is fixed to the connecting block 16. It can support the edge of the plate when the plate is large, thereby reducing the deformation of the plate caused by the sagging of the edge of the plate.

[0027] like Figure 2As shown, the bottom of the receiving platform 13 is fixedly connected to an air suction pump 2; the first support platform 14 is provided with a first air suction port 21; the first air suction port 21 and the receiving platform 13 are in a communicating relationship; the side wall of the receiving platform 13 is connected with a connecting pipe 22; the connecting pipe 22 is in a communicating relationship with the second support platform 17; the second air suction port 23 is provided on the second support platform 17; when the plate is placed on the top of the first support platform 14, the air suction pump 2 is turned on, and when the air suction pump 2 is turned on, suction is generated, and the first air suction port 21 adsorbs the plate placed on the first support platform 14. By connecting the air suction pump 2 to the bottom of the receiving platform 13 and providing the first air suction port 21 on the first support platform 14, the air suction pump 2 can generate suction on the plate placed on the first support platform 14 when it is turned on, and can adsorb the plate placed on the first support platform 14, thereby reducing the shaking of the plate placed on the first support platform 14 during the rotation of the motor 12.

[0028] like Figure 3 As shown, the side wall of the receiving platform 13 is fixed with a first pressure block 3; the first spring telescopic rod 15 is fixed with a second pressure block 31. When the panel is placed on the first support platform 14, the edge of the panel contacts the second support platform 17. At this time, the first spring telescopic rod 15 is extended. When the first spring telescopic rod 15 is extended, the first pressure block 3 and the second pressure block 31 are separated. At this time, the connecting pipe 22 remains unobstructed. When the panel is not placed on the first support platform 14, the first spring telescopic rod 15 contracts. At this time, the first pressure block 3 and the second pressure block 31 contact to squeeze the connecting pipe 22. When the connecting pipe 22 is squeezed, the sealed gas no longer passes through the connecting pipe 22. By fixing the first pressure block 3 to the side wall of the receiving platform 13 and fixing the second pressure block 31 on the first spring telescopic rod 15, the first pressure block 3 and the second pressure block 31 can contact to seal the connecting pipe 22 when the panel is not placed on the first support platform 14, thereby increasing the utilization rate of the gas.

[0029] like Figures 4 to 6 As shown, the hydraulic assembly 18 includes a bracket 4; the bracket 4 and the operating table 1 are fixedly connected; a hydraulic cylinder 41 is fixedly connected to the middle of the bracket 4; a hydraulic plate 42 is fixedly connected to the output end of the hydraulic cylinder 41; an air inlet pipe 43 is connected to the hydraulic plate 42; a plurality of air outlet holes 44 are symmetrically opened in the middle of the hydraulic plate 42. After the production of the plate is completed, a small amount of metal debris will remain on the surface. When the hydraulic plate 42 bends the plate, air is injected into the air inlet pipe 43, and the air is blown toward the surface of the plate through the air outlet holes 44. By injecting air into the air inlet pipe 43 and blowing it toward the surface of the plate through the air outlet holes 44, a small amount of metal debris remaining on the surface of the plate can be cleaned during the bending process of the plate, thereby reducing the situation where the metal debris remaining on the surface of the plate during the bending process causes scratches on the surface of the plate.

[0030] like Figures 4 to 6As shown, a pair of slots 5 are provided on the side wall of the hydraulic plate 42; a second spring telescopic rod 51 is hinged inside the pair of slots 5; a fixed block 52 is fixed at the end of the second spring telescopic rod 51; a roller 53 is rotatably connected to the inner wall of the fixed block 52. When the hydraulic plate 42 is bent, the roller 53 contacts the surface of the plate and presses the plate. When the plate is bent to a certain extent, the second spring telescopic rod 51 returns to the inside of the slot 5. By hingedly connecting the second spring telescopic rod 51 inside the slot 5, fixing the end of the second spring telescopic rod 51, and rotatably connecting the roller 53 to the inner wall of the fixed block 52, the plate can be pressed during the bending process, thereby reducing the shaking of the plate during the bending process, which affects the bending effect of the plate.

[0031] like Figure 5 As shown, a protective plate 6 is fixedly connected to the receiving platform 13; the first support platform 14 is located inside the protective plate 6. When the plate is placed on the first support platform 14, a small amount of metal debris remains on the surface. By fixing the protective plate 6 on the receiving platform 13, the metal debris dropped by the plate can be collected during the transportation of the plate, thereby reducing the metal debris from falling near the linear motor 11 and causing the linear motor 11 to become stuck.

[0032] Working principle: Place the plate on the top of the first support 14, then turn on the linear motor 11, when the linear motor 11 moves to the specified position, the hydraulic assembly 18 bends the plate, and when the bending work is completed, turn on the motor 12, and the rotation of the motor 12 drives the receiving platform 13 to rotate together. When it rotates to the specified position, the hydraulic assembly 18 bends the other side of the plate. When the plate is too large, the edge of the plate will sag. At this time, the edge of the plate will contact the second support 17. When the edge of the plate and the second support 17 contact, the second support 17 supports the edge of the plate under the action of the first spring telescopic rod 15. When the plate is placed on the top of the first support 14, turn on the vacuum pump 2. When the vacuum pump 2 is turned on, suction is generated, and the first vacuum port 21 adsorbs the plate placed on the first support 14. When the plate is placed on the first support 14, the edge of the plate contacts the second support 17. At this time, the first spring telescopic rod 15 extends. When the first spring telescopic rod 15 extends, the first pressure block 3 and the second pressure block 31 separate. At this time, the connecting pipe 2 2 keeps it unobstructed. When the panel is not placed on the first support 14, the first spring telescopic rod 15 contracts upward. At this time, the first pressing block 3 and the second pressing block 31 contact to squeeze the connecting pipe 22. When the connecting pipe 22 is squeezed, the closed gas no longer passes through the connecting pipe 22. After the panel is produced, a small amount of metal debris will remain on the surface. When the hydraulic plate 42 bends the panel, air is injected into the air inlet pipe 43, and the air is blown to the surface of the panel through the air outlet 44. By injecting air into the air inlet pipe 43 and passing through the air outlet 44 blows toward the surface of the plate, which can clean up a small amount of metal debris remaining on the surface of the plate during the bending process. When the hydraulic plate 42 is bending the plate, the roller 53 contacts the surface of the plate to press the plate. When the plate is bent to a certain extent, the second spring telescopic rod 51 returns to the inside of the card slot 5. When the hydraulic plate 42 is bending the plate, the roller 53 contacts the surface of the plate to press the plate. When the plate is bent to a certain extent, the second spring telescopic rod 51 returns to the inside of the card slot 5.
