Description

Technical Field

[0001] The invention relates to the technical field of metal plate bending, in particular to a metal plate bending machine. Background Art

[0002] A bending machine is a machine used to bend metal or other materials. It uses a relatively simple general mold to make metal sheets into certain geometric shapes. It plays a very important role in industrial production. Metal sheets are a flat product made of metal materials as raw materials. It has the advantages of high strength, corrosion resistance, good electrical and thermal conductivity, etc. During the processing of metal sheets, they need to be shaped and connected and assembled through metal cutting, stamping, bending, welding and other processes to meet their use requirements in various application fields.

[0003] The traditional bending method is that workers place the metal plate on the bottom plate, and use the driving element to press the metal plate that exceeds the bottom plate area in an arc shape to complete the bending of the metal plate. This method has been eliminated with the continuous development of society. Now there is a bending device that drives a special bending knife to bend the placed metal plate to deform the metal plate. This method is relatively common. After observing the actual processing, it is found that in actual stamping, since the metal material used in the metal plate has plastic deformation and certain elastic deformation at the same time, this results in different sizes of the finished metal plates of the same batch after the metal plate is bent, and the dimensional accuracy is poor. Therefore, the existing bending device has a yield rate to be improved when bending metal plates. Summary of the invention

DETAILED DESCRIPTION

[0039] The following will be combined with the 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0040] For example, see Figures 1 to 11 The present invention provides a metal plate bending machine, comprising a bracket 1, the inner wall of the bracket 1 is fixedly connected to a cylinder 2, the output end of the cylinder 2 is fixedly connected to a bending plate 3, and the bottom surface of the bending plate 3 is fixedly connected to a bending knife 4;

[0041] Two bodies 5 are fixedly connected to the inner wall of the bracket 1, a bottom plate 6 is fixedly connected to the inner wall of the bracket 1, two deflection plates 7 are arranged above the bottom plate 6, a nozzle 8 is arranged below the bottom plate 6, and bending parts are arranged in the two bodies 5;

[0042] The bending component comprises a transmission component and two groups of deflection components, two groups of reset components, and two groups of lubrication components. The two groups of reset components are respectively connected to the two groups of deflection components by transmission, and the two groups of lubrication components are respectively connected to the two groups of deflection components by transmission.

[0043] In this embodiment, the metal plate to be bent is first placed on the bottom plate 6 so that the part to be bent is located below the bending knife 4. After the metal plate is limited, the cylinder 2 is started to push the bending plate 3 to move in the direction close to the metal plate, thereby driving the bending knife 4 to move downward synchronously through the displacement of the bending plate 3 until it contacts the metal plate, and then the bending knife 4 continues to move downward to complete the bending of the metal plate. It is worth noting that in the above process, the metal plate itself can be limited by the existing technology so that its position will not be offset during the bending process. This process is already mature in the existing technology, and the specific principle will not be repeated here.

[0044] In the process of the vertical displacement of the bending plate 3, the transmission component in the bending component is driven to operate synchronously. Through the transmission of the transmission component, the two sets of deflection components can be driven to operate, so that the two deflection plates 7 are deflected synchronously during the bending process of the metal plate. In this way, the metal plate can be assisted to complete the bending operation smoothly by applying pressure upward on both sides of the metal plate. At the same time, this process can also reduce the phenomenon of metal plate rebound caused by insufficient force, thereby ensuring the yield rate of the bent product;

[0045] By setting two sets of reset components, after the bending of the metal plate is completed, during the recovery process at the output end of the cylinder 2, the two deflection plates 7 will not immediately perform reset reverse deflection, but wait for a period of time before performing reverse deflection. This process can keep the limit of the bent metal plate unchanged. Compared with the traditional method, this method can further avoid the rebound of the bent metal plate by limiting the position of the two deflection plates 7, thereby ensuring the bending processing accuracy.

[0046] During the operation of the two groups of deflection components, the two groups of lubrication components are driven to operate synchronously, so that when the bending knife 4 is vertically displaced, the nozzle 8 sprays lubricating oil to the area to be bent of the metal plate. This can prevent the surface of the metal plate to be processed from being too dry, and when the metal plate is bent, the area with a larger facade deformation will be damaged, thereby further ensuring the yield rate.

[0047] Also, see Figures 1 to 6 ,as well as Fig.10 The transmission component includes a transmission rod 9, which is fixedly connected to the top surface of the bending plate 3. The inner wall of the bracket 1 is provided with a slide groove 1 for the transmission rod 9 to move. The surface of the body 5 is provided with a slide groove 2. The groove wall of the slide groove 2 is slidably connected with an L-shaped rod 10. The inner wall of the L-shaped rod 10 is provided with a displacement groove 1. The groove wall of the displacement groove 1 is slidably connected with a connecting rod 11. The inner wall of the bracket 1 is slidably connected to the rod wall of the L-shaped rod 10. The end of the L-shaped rod 10 is fixedly connected with a push plate 12. The push plate 12 and the inner wall of the bracket 1 are jointly fixedly connected with a return spring 13.

[0048] In this embodiment, the transmission rod 9 is synchronously driven to move vertically downward by the vertical downward movement of the bending plate 3. During the vertical downward movement of the transmission rod 9, at the beginning of the second half of the displacement, the L-shaped rod 10 is contacted, thereby pushing the L-shaped rod 10 downward by the downward movement of the transmission rod 9. At the beginning of this state, the bending knife 4 does not contact the metal plate. During the downward movement of the L-shaped rod 10, the push plate 12 is pushed to move downward synchronously, causing the reset spring 13 to deform. At the same time, the connecting rod 11 is synchronously driven to move downward by the downward movement of the L-shaped rod 10.

[0049] See also Figures 1 to 8The deflection component includes a steering groove 14, which includes two vertical grooves 15 and two inclined grooves 16. The rod wall of the connecting rod 11 is slidably connected to the groove wall of the steering groove 14. The inner wall of the bracket 1 is slidably connected with a rod 17. The rod wall of the rod 17 is provided with a displacement groove 2. The groove wall of the displacement groove 2 is slidably connected to the rod wall of the connecting rod 11. The inner wall of the body 5 is rotatably connected with a deflection shaft 18. The shaft arm of the deflection shaft 18 is fixedly connected with a deflection cylinder 19. The side wall of the deflection cylinder 19 is provided with a deflection groove 20. The surface of the rod 17 is fixedly connected with a fixed shaft 21. The shaft arm of the fixed shaft 21 is slidably connected to the groove wall of the deflection groove 20. The deflection plate 7 is fixedly connected to the shaft arm of the deflection shaft 18.

[0050] In this embodiment, the connecting rod 11 moves downward in the above process, so that the connecting rod 11 slides downward along the groove wall of the steering groove 14. At this time, the connecting rod 11 slides along the groove wall of the displacement groove 2 on the rod 17. As the connecting rod 11 slides, when it is constrained by the inclined groove 16 and approaches the metal plate, it slides along the displacement groove 1 on the L-shaped rod, and at the same time pushes the rod 17 to approach the metal plate. In this state, the bending knife 4 begins to contact the metal plate. At this time, the displacement of the rod 17 in the direction of the metal plate synchronously drives the fixed shaft 21 to move. In this way, under the constraint of the deflection groove 20, the displacement of the fixed shaft 21 causes the deflection cylinder 19 to be deflected, and then the deflection of the deflection cylinder 19 causes the deflection shaft 18 to be deflected, so that the deflection plate 7 is deflected through the transmission of the deflection shaft 18;

[0051] In this way, the two deflection plates 7 can synchronously generate deflection to apply upward pressure to both sides of the metal plate, thereby assisting the metal plate to smoothly complete the bending operation. At the same time, this process can also reduce the occurrence of metal plate rebound caused by insufficient force, thereby ensuring the yield rate of the bent product.

[0052] See also Figures 3 to 9 The reset component includes two triangular blocks 22, which are respectively located at the two intersections of the two vertical grooves 15 and the two oblique grooves 16. The two triangular blocks 22 are slidably connected to the inner wall of the body 5. The surfaces of the two triangular blocks 22 are fixedly connected with steering springs 23, and the ends of the two steering springs 23 are fixedly connected to the inner wall of the body 5.

[0053] In this embodiment, when the connecting rod 11 moves down along the vertical groove 15 on the steering groove 14 and then moves along the inclined groove 16, at the end of the bending process, the connecting rod 11 will contact the inclined surface of the triangular block 22. At this time, the displacement of the last end path of the connecting rod 11 will push the triangular block 22 to slide along the inner wall of the body 5, so that the corresponding steering spring 23 is compressed, that is, the triangular block 22 in this state will not hinder the displacement of the connecting rod 11. When the structure is reset, because the connecting rod 11 is in direct contact with the adjacent triangular block 22 at this time, under the obstruction of the triangular block 22, the connecting rod 11 cannot be reset along the original inclined groove 16, but first moves along the vertical groove 15, and then slides along the inclined groove 16 to reset to the original position, that is, the reset path of the connecting rod 11 is a path with parallelogram characteristics. In this process, the reset of the connecting rod 11 will first slide along the displacement groove 2 on the rod 17, and then slide along the displacement groove 1 on the L-shaped rod 10;

[0054] In this way, during the recovery process at the output end of the cylinder 2, the two deflection plates 7 will not immediately perform a reset reverse deflection, but will wait for a period of time before performing a reverse deflection. This process can maintain the limit position of the metal plate that has just been bent unchanged. Compared with the traditional method, this method can further avoid the rebound phenomenon of the metal plate that has just been bent by delaying the reset of the two deflection plates 7, thereby ensuring the bending processing accuracy.

[0055] Embodiment 2, based on the above embodiment:

[0056] See also Figures 3 to 11 The lubricating component includes a rack row 24 and a piston cylinder 25. The rack row 24 is fixedly connected to the rod wall of the connecting rod 11. The inner wall of the body 5 is rotatably connected to a lubrication shaft 26. The shaft arm of the lubrication shaft 26 is fixedly connected to a gear 27. The teeth of the gear 27 mesh with the teeth of the rack row 24. The shaft arm of the lubrication shaft 26 is fixedly connected to a rotating rod 28. The end of the rotating rod 28 is fixedly connected to a connecting shaft 29. The inner wall of the bracket 1 is slidably connected to a displacement rod group 30. The end of the displacement rod group 30 is fixedly connected to the inner wall of the bracket 1. The part is fixedly connected with a displacement frame 31, the inner wall of the displacement frame 31 is slidably connected with the shaft arm of the connecting shaft 29, the rod wall of the displacement rod group 30 is slidably connected with the inner wall of the piston cylinder 25, the end of the displacement rod group 30 is fixedly connected with a piston plate 32, the piston cylinder 25 is fixedly connected with a liquid inlet pipe 33 and a liquid outlet pipe 34, the end of the liquid inlet pipe 33 is fixedly connected with a lubricating cylinder 35, the end of the liquid outlet pipe 34 is fixedly connected with the nozzle 8, and a one-way valve is provided on both the liquid inlet pipe 33 and the liquid outlet pipe 34.

[0057] In this embodiment, when the connecting rod 11 moves vertically downward along the vertical groove 15, the rack row 24 is synchronously driven to move downward, so that the gear 27 can rotate, and then the connecting shaft 29 at the end of the rotating rod 28 is displaced in a circular trajectory through the transmission of the lubricating shaft 26. Through the circumferential trajectory displacement of the connecting shaft 29, the displacement frame 31 can be displaced back and forth in the vertical direction under the limit of the bracket 1, that is, the displacement rod group 30 is displaced back and forth vertically along the inner wall of the bracket 1, and through the displacement rod group 3 0 vertical reciprocating movement, the piston plate 32 can be reciprocated in the piston cylinder 25. When the piston plate 32 moves upward, the one-way valve on the liquid inlet pipe 33 is opened and the one-way valve on the liquid outlet pipe 34 is closed, so that the lubricating oil in the lubricating cylinder 35 can be drawn into the piston cylinder 25. When the piston plate 32 moves downward, the one-way valve on the liquid inlet pipe 33 is closed and the one-way valve on the liquid outlet pipe 34 is opened, so that the lubricating oil in the piston cylinder 25 can be sprayed out from the nozzle 8 to the bottom surface of the bent part of the metal plate through the liquid outlet pipe 34;

[0058] This method can prevent the surface of the metal plate to be processed from being too dry. When the metal plate is bent, the facade is stretched and the area with larger deformation is damaged, thereby further ensuring the yield rate;

[0059] At the same time, this approach is adopted by Figure 7 It can be seen from the middle structural position that when the bending knife 4 contacts the metal plate and starts to bend the metal plate, the rack row 24 has been separated from the gear 27, that is, too much lubricating oil will not be applied to the metal plate at this time, and the application process is carried out before the metal plate is bent. This can be preventive. Under the premise of ensuring that the lubricating oil is applied in place, excessive waste of lubricating oil can be avoided.

[0060] Embodiment 3, based on the above embodiment:

[0061] See also Figure 1 The surface of the bracket 1 is detachably connected with a collecting frame 36, and the outer wall of the collecting frame 36 is affixed with a non-slip cloth strip. Through the setting of the collecting frame 36, the flowing lubricating oil can be collected and can be reused after filtering.

[0062] See also Figure 1 The size of the transmission rod 9 is adapted to the size of the L-shaped rod 10, and the transmission rod 9 and the L-shaped rod 10 are located in the same vertical plane. By limiting the size and position of the L-shaped rod 10 and the transmission rod 9, it is ensured that the L-shaped rod 10 can be smoothly pushed downward during the downward movement of the transmission rod 9.

[0063] See also Fig. 9The size of the triangular block 22 is adapted to the size of the steering slot 14, and the inclined surface of the triangular block 22 is oriented toward the inclined slot 16. By limiting the position state of the triangular block 22, the triangular block 22 can smoothly exert its effect of changing the delayed deflection of the deflection plate 7.

[0064] Working principle: When the metal plate bending machine is used, the metal plate to be bent can be placed on the bottom plate 6 first, so that the part to be bent is located below the bending knife 4. After the metal plate is limited, the cylinder 2 is started, and the bending plate 3 is pushed by the cylinder 2 to move in the direction close to the metal plate, so that the bending knife 4 is driven to move downward synchronously through the displacement of the bending plate 3. In the process of the vertical displacement of the bending plate 3, the two deflection plates 7 are deflected synchronously through the transmission of the transmission parts, so that the metal plate can be assisted to complete the bending smoothly through the process of applying pressure upward on both sides of the metal plate. Bending operation, at the same time, this process can also reduce the phenomenon of metal plate rebound caused by insufficient force, thereby ensuring the yield rate of the bent product. In the process of resetting after bending, through the setting of two sets of resetting components, after the bending of the metal plate is completed, the two deflection plates 7 will not immediately perform the resetting reverse deflection, but wait for a period of time before reversing. Through this process, the limit of the bent metal plate can be kept unchanged. Compared with the traditional method, this method can further avoid the rebound of the bent metal plate through the limit of the two deflection plates 7, thereby ensuring the bending processing accuracy.

[0065] At the same time, when the bending knife 4 is vertically displaced, the nozzle 8 sprays lubricating oil onto the area to be bent of the metal plate. This can prevent the surface of the metal plate to be processed from being too dry, and prevent the area with a larger facade deformation from being damaged when the metal plate is bent, thereby further ensuring the yield rate.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
