Description

Technical Field

[0001] The invention belongs to the technical field of bending machines, and particularly relates to an adaptive bending angle adjustment system for a pure electric bending machine. Background Art

[0002] In the field of sheet metal processing, due to the inherent characteristics of the production process and its wide application requirements in many industries, sheet metal usually takes a flat state as the initial form. However, in the actual production process, in order to meet the requirements of different product structures and functions, it is often necessary to bend the sheet metal. At present, when facing the task of sheet metal bending, due to the diversity of the sheet metal itself in terms of material size, specifications, etc., manual bending operations face many limitations and are difficult to effectively implement. Therefore, hydraulic bending machines have become commonly used equipment in sheet metal bending processing.

[0003] The working principle of the existing hydraulic bending machine is mainly to apply a downward pressure to the middle part of the sheet metal to achieve the bending and forming of the sheet metal. However, in the actual operation process, this bending method has significant defects. Specifically, when using a hydraulic bending machine for bending, the adjustment of the descending depth mainly depends on manual visual inspection. This adjustment method lacks accuracy and stability, and it is difficult for operators to accurately control the corresponding relationship between the descending depth and the bending angle. Due to the inability to accurately control the bending angle, the bent sheet metal often has a bending angle deviation, which cannot meet the design requirements, resulting in the production of a large number of unqualified products, not only increasing the production cost, but also affecting the production efficiency and product quality. Summary of the Invention

[0004] The invention aims to solve the technical problems existing in the prior art; for this purpose, the invention proposes an adaptive bending angle adjustment system for a pure electric bending machine.

[0005] The purpose of the invention can be achieved by the following technical solutions:

[0006] An adaptive bending angle adjustment system for a pure electric bending machine, comprising a fixed seat, and an adjustment groove is penetrated through the top of the fixed seat.

[0007] Two adjustment plates are rotatably connected in the adjustment groove, a liftable support plate is arranged on the fixed seat, the support plate is used for adjusting the angle of the adjustment plate, and the support plate is in contact with the adjustment plate. An arc-shaped track with scales is fixedly connected to the fixed seat, a convex rod capable of moving on the arc-shaped track is fixedly connected to the adjustment plate, and a pointer is fixedly connected to the convex rod.

[0008] As a further scheme of the invention: a through groove is penetrated through one side of the adjustment plate, and the bottom of the through groove cavity is open.

[0009] As a further solution of the present invention: a ejecting rod is slidably connected to the supporting plate, a connecting frame is fixedly connected to the bottom end of the ejecting rod, a first spring is sleeved outside the ejecting rod, and the first spring is fixedly connected to the supporting plate and the connecting frame respectively.

[0010] As a further solution of the present invention: a through hole is formed through the top of the fixed seat, a movable plate is slidably connected in the through hole, and a pressing plate is slidably connected to the movable plate.

[0011] As a further solution of the present invention: a supporting frame is fixedly connected to the fixed seat, and a transmission member is arranged on the supporting frame.

[0012] As a further solution of the present invention: a movable frame capable of resetting is arranged on the supporting plate, a rack capable of adjusting height is arranged on the movable frame, and the rack is used in cooperation with the transmission member to realize the lifting of the movable plate.

[0013] As a further solution of the present invention: the movable frame is slidably connected to the supporting plate, a straight rod is fixedly connected to the movable frame, and the straight rod is slidably connected to the supporting plate.

[0014] As a further solution of the present invention: a second spring is sleeved on the straight rod, and the second spring is fixedly connected to the movable frame and the supporting plate respectively.

[0015] As a further solution of the present invention: two cylinders are fixedly connected to the fixed seat, and the two cylinders are fixedly connected to the supporting plate.

[0016] As a further solution of the present invention: two limiting strips are fixedly connected to the supporting plate, and the limiting strips are used to limit the rotation angle of the adjusting plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By flexibly adjusting the height of the supporting plate in the present application, the adjusting plate will rotate controllably. With the precise alignment of the pointer and the corresponding scale, the operator can quickly and intuitively obtain the accurate angle value of the adjusting plate, greatly improving the accuracy and convenience of angle adjustment. In the actual application scenario of sheet metal bending, when the bending part of the sheet metal is closely attached to the adjusting plate, the specific angle of the adjusting plate can be directly and accurately transmitted to the sheet metal, so that the sheet metal can be easily bent into the required specific angle. The efficiency of the bending operation is significantly improved.

[0019] 2. The present application cooperates with the ejector rod and spring 1. After the sheet bending operation is completed, spring 1 will accurately act on the ejector rod by virtue of its own elastic restoring force. At this time, the ejector rod, driven by the elastic force of the spring, can automatically and smoothly eject the sheet from the bending station. The operator can directly move the sheet out of the bending machine horizontally, completely abandoning the cumbersome process of traditional operations in which the sheet must be lifted laboriously first and then moved horizontally. It not only greatly saves manpower and time costs and reduces the labor intensity of operators, but also effectively improves the overall efficiency of the sheet bending process and avoids problems such as sheet damage that may be caused by cumbersome operations.

[0020] 3. This application uses a movable plate, a pressure plate, a transmission part and a rack to cooperate with each other. When bending a specific part of the plate, the design can simultaneously achieve precise flattening of the parts of the plate that do not need to be bent. Through the coordinated operation of various components, the undesirable phenomenon of warping of the non-bending parts of the plate during the bending process is effectively avoided. This innovative design not only significantly improves the quality of the plate bending process, ensures that the bent plate remains flat and regular, meets high-precision processing requirements, but also greatly enhances the stability and reliability of the processing process. At the same time, it reduces the defective rate caused by the warping of the plate, reduces production costs, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] Please refer to Figures 1-4 As shown, this application provides a pure electric bending machine adaptive bending angle adjustment system, including a fixed seat 1, and an adjustment groove 2 is penetrated and opened at the top of the fixed seat 1;

[0032] Two adjusting plates 3 are rotatably connected in the adjusting groove 2. A liftable supporting plate 4 is arranged on the fixed seat 1. The supporting plate 4 is used for adjusting the angle of the adjusting plate 3, and the supporting plate 4 is in contact with the adjusting plate 3. An arc-shaped track 5 with scales is fixedly connected to the fixed seat 1. A convex rod 6 capable of moving on the arc-shaped track 5 is fixedly connected to the adjusting plate 3. A pointer 24 is fixedly connected to the convex rod 6. The scales on the arc-shaped track 5 are not drawn. According to the bending requirements of the plate, the angle of the adjusting plate 3 is adjusted. During the adjustment process, a cylinder 22 is used to drive the supporting plate 4 to lift. After that, the adjusting plate 3 will rotate controllably, thereby realizing an accurate change in its angle. The pointer 24 will move synchronously with the adjusting plate 3 through the convex rod 6. By accurately aligning the pointer 24 with the corresponding scales, the operator can quickly and intuitively obtain the accurate angle value of the adjusting plate 3, greatly improving the accuracy and convenience of angle adjustment. After that, the plate is bent. During the bending process, the plate is stressed and recessed into the adjusting groove 2. When the bent part of the plate is in close contact with the adjusting plate 3, the specific angle of the adjusting plate 3 can be directly and accurately transmitted to the plate, so that the plate can be easily bent into the required specific angle. This not only effectively avoids the problem of plate scrapping caused by inaccurate angle control in the traditional bending method, greatly improves the qualification rate of plate bending, but also significantly improves the efficiency of the bending operation, reduces the production cost, and brings significant economic benefits and technological improvements to the plate processing industry.

[0033] A through groove 7 is formed through one side of the adjusting plate 3, and the bottom of the groove cavity of the through groove 7 is open.

[0034] Two cylinders 22 are fixedly connected to the fixed seat 1. The cylinders 22 are electrically connected to an external power supply and are controlled by an external control program. The two cylinders 22 are fixedly connected to the supporting plate 4.

[0035] Two limiting strips 23 are fixedly connected to the supporting plate 4. The limiting strips 23 are used for limiting the rotation angle of the adjusting plate 3.

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, refer to Figure 4 and Figure 5 as shown.

[0038] The support plate 4 is slidably connected to an ejector rod 8. The ejector rod 8 is designed with two sections, one upper and one lower, and can be extended and retracted via a threaded structure. The bottom end of the ejector rod 8 is fixedly connected to a connecting frame 9. A spring 10 is sleeved around the outer portion of the ejector rod 8, which is fixedly connected to both the support plate 4 and the connecting frame 9. During the sheet bending process, the concave portion of the sheet presses against the ejector rod 8, forcing the ejector rod 8 downward, thereby lowering the connecting frame 9. The spring 10 is then forced into an extended state. After the sheet bending operation is completed, the spring 10, with its inherent elastic restoring force, precisely acts on the ejector rod 8. At this point, driven by the spring force, the ejector rod 8 automatically and smoothly ejects the sheet from the bending station. The operator can then directly and smoothly remove the sheet from the bending machine horizontally, completely eliminating the cumbersome process of traditional operations that requires laboriously lifting the sheet and then horizontally removing it. It not only greatly saves manpower and time costs and reduces the labor intensity of operators, but also effectively improves the overall efficiency of sheet metal bending processing and avoids problems such as sheet metal damage that may be caused by tedious operations.

[0039] Example 3

[0040] Based on Example 1, see Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 shown.

[0041] The top of the fixing base 1 is penetrated by a through hole 11, in which a movable plate 12 is slidably connected, and a pressing plate 13 is slidably connected to the movable plate 12. There are four through holes 11, and one pressing plate 13 is connected to two movable plates 12 together.

[0042] A support frame 14 is fixedly connected to the fixed seat 1, and a transmission member 15 is arranged on the support frame 14. The transmission member 15 includes a lead screw 151 rotatably connected to the support frame 14 and a support seat 152 fixedly connected to the support frame 14. The lead screw 151 is threadedly connected to the movable plate 12. A cross bar 153 is rotatably connected to the support seat 152. Bevel gears 154 are fixedly connected to both the cross bar 153 and the lead screw 151, and the two bevel gears 154 mesh with each other. A gear 155 is fixedly connected to the cross bar 153. The threads of the lead screws 151 at both ends of the same cross bar 153 are arranged in opposite directions, so that the movable plates 12 on the two lead screws 151 are driven to move up and down synchronously by the rotation of the cross bar 153. During the process of bending the plate, the downward movement of the connecting frame 9 will drive the moving frame 16 to move downward, and then drive the rack 17 to move downward. Thus, the gear 155 is driven to rotate under the meshing action, and then drive the cross bar 153 to rotate. Under the meshing transmission of the two bevel gears 154, the lead screw 151 is driven to rotate, so as to drive the movable plate 12 to move downward, and then drive the pressing plate 13 to move downward, so that the pressing plate 13 presses on the plate, and the precise flattening process of the non-bending part of the plate can be realized synchronously. Through the coordinated operation of each component, the phenomenon that the non-bending part of the plate warps during the bending process is effectively avoided. This innovative design not only significantly improves the quality of plate bending processing, ensures that the bent plate remains flat and regular, meets the high-precision processing requirements, but also greatly enhances the stability and reliability of the processing process. At the same time, it reduces the defective rate caused by the warping of the plate, reduces the production cost, and improves the production efficiency. And after the plate bending operation is completed, as the rack 17 moves upward, it will drive the pressing plate 13 to return to its original position, so as to facilitate the flattening process of the subsequent plates.

[0043] A movable frame 16 that can be reset is arranged on the support plate 4. An adjusting screw 18 is rotatably connected to the movable frame 16. An L-shaped plate 19 is threadedly connected to the adjusting screw 18. A rack 17 is fixedly connected to the L-shaped plate 19. The L-shaped plate 19 is slidably connected to the movable frame 16. The rack 17 meshes with the gear 155.

[0044] The movable frame 16 is slidably connected to the support plate 4. A straight rod 20 is fixedly connected to the movable frame 16. The straight rod 20 is slidably connected to the support plate 4.

[0045] A second spring 21 is sleeved on the straight rod 20, and the second spring 21 is fixedly connected to the moving frame 16 and the support plate 4 respectively. By sliding the moving frame 16 on the connecting frame 9, the straight rod 20 moves towards the inside of the connecting frame 9, and the second spring 21 is in a compressed state under force. Then, the adjusting screw 18 is rotated to drive the L-shaped plate 19 to move up and down, thereby driving the rack 17 to move up and down, realizing the height adjustment of the rack 17, and ensuring that the adjusted rack 17 can mesh with the gear 155. By adjusting the height of the rack 17, the transmission between the rack 17 and the gear 155 can be utilized to realize the lifting of the movable plate 12 by different distances, so that the pressing plate 13 can be conveniently adapted to flatten plates of different thicknesses.

[0046] Embodiment 4

[0047] Combined with Embodiment 1, Embodiment 2 and Embodiment 3, see Figures 1-7 as shown.

[0048] By flexibly adjusting the height of the support plate 4, the adjusting plate 3 will rotate controllably. With the precise alignment of the pointer 24 with the corresponding scale, the operator can quickly and intuitively obtain the accurate angle value of the adjusting plate 3, greatly improving the accuracy and convenience of angle adjustment. In the actual application scenario of sheet metal bending, when the bent part of the sheet is in close contact with the adjusting plate 3, the specific angle of the adjusting plate 3 can be directly and accurately transmitted to the sheet, so that the sheet can be easily bent into the required specific angle. The efficiency of the bending operation is significantly improved.

[0049] The working principle of the present invention: Place the sheet on the fixed seat 1. Then, slide the pressing plate 13 on the movable plate 12 to adjust the position of the pressing plate 13, so that the pressing plate 13 can press on the sheet when it descends.

[0050] After that, according to the bending requirements of the sheet, adjust the angle of the adjusting plate 3. During the adjustment process, use the air cylinder 22 to drive the support plate 4 to move up and down. Then, the adjusting plate 3 will rotate controllably, thereby realizing the precise change of its angle. The pointer 24 will move synchronously with the adjusting plate 3 through the convex rod 6. With the precise alignment of the pointer 24 with the corresponding scale, the operator can quickly and intuitively obtain the accurate angle value of the adjusting plate 3, greatly improving the accuracy and convenience of angle adjustment.

[0051] The sheet is then bent. During the bending process, the sheet is forced to indent into the adjustment slot 2. When the bent portion of the sheet is in close contact with the adjustment plate 3, the specific angle of the adjustment plate 3 is directly and accurately transmitted to the sheet, allowing the sheet to be easily bent to the desired angle. This not only effectively avoids the problem of sheet scrapping caused by inaccurate angle control in traditional bending methods, greatly improving the pass rate of sheet bending, but also significantly improves the efficiency of the bending operation, reduces production costs, and brings significant economic benefits and technological improvements to the sheet processing industry.

[0052] During the sheet bending process, the concave part of the sheet will press on the ejector rod 8, so that the ejector rod 8 is forced to move downward, thereby driving the connecting frame 9 to descend, and the spring 10 is forced to be in an extended state. After the sheet bending operation is completed, the spring 10 will accurately act on the ejector rod 8 by virtue of its own elastic recovery force. At this time, the ejector rod 8, driven by the spring force, can automatically and smoothly eject the sheet from the bending station. The operator can directly move the sheet out of the bending machine horizontally, completely abandoning the cumbersome process of traditional operations in which the sheet must be laboriously lifted and then moved horizontally. It not only greatly saves manpower and time costs and reduces the labor intensity of operators, but also effectively improves the overall efficiency of the sheet bending process and avoids problems such as sheet damage that may be caused by cumbersome operations.

[0053] Simultaneously, during the sheet bending process, the descent of the connecting frame 9 drives the movable frame 16 downward, which in turn drives the rack 17 downward. This meshing action drives the gear 155 to rotate, which in turn drives the crossbar 153. The meshing of the two bevel gears 154 drives the screw 151 to rotate, which in turn drives the movable plate 12 downward, and thus the pressure plate 13 downward, so that the pressure plate 13 presses against the sheet, simultaneously achieving precise flattening of the sheet's non-bending areas. The coordinated operation of these components effectively prevents the undesirable phenomenon of sheet warping in non-bending areas during the bending process. This innovative design not only significantly improves the quality of sheet bending, ensuring that the bent sheet remains flat and regular after bending, meeting high-precision machining requirements, but also greatly enhances the stability and reliability of the process. It also reduces the defective rate caused by sheet warping, lowers production costs, and improves production efficiency. After the sheet bending operation is completed, the upward movement of the rack 17 drives the pressure plate 13 back to its original position, facilitating the flattening of subsequent sheets.
