Description

Technical Field

[0001] This utility model belongs to the field of frame sheet metal processing technology, specifically relating to a frame sheet metal bending device. Background Technology

[0002] A frame-type sheet metal bending device is a mechanical device used to bend and shape sheet metal. It typically uses mechanical or hydraulic force to drive a die to apply pressure to the sheet metal. Through the cooperation of the upper and lower dies, vertical pressure is applied to the sheet metal, causing it to undergo plastic deformation at a specific angle and shape. Its core function is to process flat sheet metal materials into three-dimensional structures that meet design requirements, and it is widely used in various industrial manufacturing fields. By using a frame-type sheet metal bending device, not only can flat sheet metal be processed into three-dimensional structures to meet product functional requirements, but manual intervention can also be reduced, production efficiency improved, and it is suitable for mass production.

[0003] Chinese Patent Publication No. CN221966470U discloses a continuous bending device for sheet metal parts, belonging to the field of sheet metal processing technology. This continuous bending device includes a bending assembly and an ejection assembly. The bending seat is fixedly connected to the output end of a hydraulic cylinder. First, the hydraulic cylinder moves the bending seat downwards, allowing continuous bending of the sheet metal parts on the bending table surface. After bending, a cylinder moves the top plate, lifting the bent sheet metal parts and quickly removing them from the bending table. Secondly, the bending table's sliding connection between the pass-through clip and the support plate facilitates disassembly and installation of the bending table, eliminating the need for special tools. This streamlined process also facilitates the removal of the bent sheet metal parts, improving practicality.

[0004] In practical use, this utility model can process sheet metal parts to a preset angle. However, the mechanical structure design of existing frame sheet metal bending devices generally has fixed characteristics. The geometric parameters of the upper and lower dies are usually fixed by rigid connection or mechanical limit assembly, which makes the adjustment of the bending angle highly dependent on the replacement of the die. When it is necessary to bend the frame sheet metal parts to other angles, the machine must be stopped, the original die must be disassembled, and a die assembly with the appropriate angle must be reinstalled. This process not only involves the disassembly and calibration of the die, but also requires the coordinated adjustment of the slider stroke, pressure parameters, etc., which leads to the interruption of the production process and the loss of efficiency, thus making the applicability of the frame sheet metal bending device somewhat lacking. Utility Model Content

[0005] This utility model proposes a bending device for machine frame sheet metal parts to solve the problem of difficulty in flexibly processing machine frame sheet metal parts with different angles in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bending device for machine frame sheet metal parts, comprising:

[0007] Mounting base and support frame;

[0008] Two arc-shaped plates are respectively disposed on both sides of the upper end of the mounting base, the support frame is disposed on the upper end of the mounting base, and two limiting plates are rotatably connected between the two arc-shaped plates;

[0009] Two adjusting plates are respectively set on one side of two limiting plates. A rectangular groove is opened in the mounting base, and a threaded rod is rotatably connected in the rectangular groove. The external threads on both sides of the threaded rod are arranged in opposite directions.

[0010] The mounting frame is located inside the upper part of the support frame. The mounting frame is U-shaped and has a positioning column rotatably connected inside. Multiple upper modules are provided on the outside of the positioning column, and the size of the multiple upper modules is arranged in an increasing manner.

[0011] In order to bend the frame sheet metal parts into different angles, the two adjustment plates are further provided with limit grooves on the side near the limit plate. The two limit plates are respectively located in the two limit grooves. The two limit grooves are provided with limit rods. The two limit plates are provided with limit openings that are adapted to the limit rods. The two limit rods are respectively passed through the two limit openings and are slidably connected to the side walls of the limit openings.

[0012] In a preferred embodiment, each of the two adjusting plates has a sliding plate at its bottom end. The bottom ends of the two sliding plates extend to both sides of the rectangular groove and are respectively provided with threaded holes adapted to the threaded rod. The threaded rod passes through the two threaded holes and is threadedly connected to the side wall of the threaded hole. A servo motor is provided on one side of the rectangular groove, and one end of the threaded rod is set on the output end of the servo motor. A control panel is provided on one side of the mounting base.

[0013] In a preferred embodiment, the mounting base has fixing plates on both sides of its upper end, and the two adjusting plates have multiple guide rods on the side near the fixing plates, with the multiple guide rods passing through the two fixing plates respectively.

[0014] In a preferred embodiment, both of the arc-shaped plates are provided with scale values ​​on the side near the limiting plate.

[0015] In a preferred embodiment, the upper end of the support frame is provided with an electric push rod, the output end of which passes through the support frame and is located at the upper end of the mounting frame. The upper end of the mounting frame is provided with multiple locking rods, all of which pass through the support frame.

[0016] In a preferred embodiment, the positioning post is provided with multiple positioning holes, and locking pins adapted to the positioning holes are provided on both sides of the mounting frame. One end of each of the two locking pins extends to both sides of the positioning hole located at the upper end.

[0017] To ensure the accuracy of bending the sheet metal parts of the frame, both of the arc-shaped plates are further provided with arc-shaped grooves, and both of the two limiting plates are provided with fixing screws that are adapted to the arc-shaped grooves on both sides. The two fixing screws on both sides pass through the two arc-shaped grooves on both sides respectively, and are provided with fixing nuts. The two fixing nuts on both sides abut against one side of the two arc-shaped plates respectively.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model, through the movable adjustment plates and limiting rods set on both sides of the upper end of the mounting base, combined with the preset limiting ports inside the two limiting plates, can realize the rapid adjustment of the included angle of the two limiting plates. With the help of multiple upper modules of different sizes on the outside of the positioning column, the operator only needs to slide the adjustment plate to the designated position and lock the limiting rod to match the corresponding upper module to complete the bending angle switching. This not only saves the traditional mold disassembly and installation process, but also avoids the accumulation of positioning errors caused by frequent mold changes, significantly improving the efficiency and accuracy of multi-angle bending of the frame sheet metal parts, making the frame sheet metal bending device more applicable.

[0020] 2. This utility model, through the combination structure of fixing screws and fixing nuts set at both ends of the two limiting plates, can further enhance the stability of the limiting plates after angle adjustment. After the limiting plates have completed angle adjustment, by tightening the fixing nuts at both ends of the fixing screws, the fixing nuts are pressed against the side wall of the arc plate. The small displacement gap after angle adjustment can be eliminated through mechanical locking effect, effectively suppressing the angle deviation of the limiting plates caused by uneven force or vibration of the plate during bending. This ensures that the limiting plates always maintain the preset angle during bending processing, significantly enhancing the processing stability and finished product consistency of the bending device under complex working conditions.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] Please see Figure 1-4 This utility model provides a bending device for machine frame sheet metal parts, comprising:

[0029] Mounting base 1 and support frame 2;

[0030] Two arc-shaped plates 3 are respectively set on both sides of the upper end of the mounting base 1, and the support frame 2 is set on the upper end of the mounting base 1. Two limiting plates 4 are rotatably connected between the two arc-shaped plates 3.

[0031] Two adjusting plates 5 are respectively set on one side of the two limiting plates 4. A rectangular groove is opened in the mounting base 1. A threaded rod 6 is rotatably connected in the rectangular groove. The external threads on both sides of the threaded rod 6 are arranged in opposite directions.

[0032] Mounting frame 7 is located inside the upper part of support frame 2. Mounting frame 7 is U-shaped and is rotatably connected to positioning column 8 inside. Multiple upper modules 9 are provided on the outside of positioning column 8, and the size of the multiple upper modules 9 is set in an increasing manner.

[0033] Specifically, such as Figure 2 and Figure 3 As shown, each of the two adjusting plates 5 has a limiting groove on the side near the limiting plate 4. The two limiting plates 4 are located in the two limiting grooves respectively. Each of the two limiting grooves is provided with a limiting rod 10. Each of the two limiting plates 4 has a limiting port that is adapted to the limiting rod 10. The two limiting rods 10 pass through the two limiting ports respectively and are slidably connected to the side wall of the limiting port.

[0034] Through its design, when the two adjusting plates 5 move, they will drive the two limiting rods 10 to move respectively. In conjunction with the limiting ports in the two limiting plates 4, the included angle of the two limiting plates 4 can be easily adjusted, so that the bending device can bend the sheet metal parts of each frame into different angles, thus improving the applicability of bending for specialized use.

[0035] Specifically, such as Figure 2 As shown, each of the two adjusting plates 5 has a sliding plate 11 at its bottom end. The bottom ends of the two sliding plates 11 extend to both sides of the rectangular groove and are respectively provided with threaded holes that are adapted to the threaded rod 6. The threaded rod 6 passes through the two threaded holes and is threadedly connected to the side wall of the threaded hole. A servo motor 12 is provided on one side of the rectangular groove. One end of the threaded rod 6 is set on the output end of the servo motor 12. A control panel 13 is provided on one side of the mounting base 1. The servo motor 12 and the control panel 13 are existing technologies and will not be described in detail here. When the servo motor 12 is started, its output end will drive the threaded rod 6 to rotate. The threaded rod 6 can drive the two sliding plates 11 to move in opposite directions. The two sliding plates 11 will drive the two adjusting plates 5 to move respectively, thereby adjusting the angle of the two limiting plates 4. When the threaded rod 6 stops rotating, the position of the two sliding plates 11 and the two adjusting plates 5 can be locked according to the characteristics of the threaded rod 6, thereby preventing the angle of the two limiting plates 4 from shifting during use and ensuring the accuracy of bending the sheet metal parts of the frame.

[0036] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the mounting base 1 has fixed plates 14 on both sides of the upper end. The two adjusting plates 5 are provided with multiple guide rods 15 on the side near the fixed plates 14. The multiple guide rods 15 pass through the two fixed plates 14 respectively. The two fixed plates 14 and the multiple guide rods 15 can limit the movement of the two adjusting plates 5 and prevent their position from shifting, thereby ensuring the bending accuracy of the frame sheet metal parts.

[0037] Specifically, such as Figure 2 and Figure 3 As shown, both arc plates 3 are provided with scale values ​​16 on the side near the limiting plate 4. The scale values ​​16 on the two arc plates 3 can be used to precisely adjust the angle of the two limiting plates 4, thereby ensuring the quality of bending the frame sheet metal parts.

[0038] Specifically, such as Figure 1 and Figure 2 As shown, the upper end of the support frame 2 is provided with an electric push rod 17. The electric push rod 17 is existing technology and will not be described in detail here. The output end of the electric push rod 17 passes through the support frame 2 and is set at the upper end of the mounting frame 7. The upper end of the mounting frame 7 is provided with multiple locking rods 18, all of which pass through the support frame 2. The multiple locking rods 18 can limit the vertical movement of the mounting frame 7 to prevent its position from shifting, thereby ensuring the accuracy of bending the sheet metal parts of the frame.

[0039] Specifically, such as Figure 2 and Figure 4As shown, the positioning post 8 is provided with multiple positioning holes, and the mounting frame 7 is provided with locking pins 19 that are adapted to the positioning holes on both sides. One end of each locking pin 19 extends to the two sides of the positioning hole at the upper end. The movable locking pins 19 on both sides of the mounting frame 7 can limit the position of the positioning post 8 without affecting its rotation, thereby ensuring the stability of the upper module 9 when bending.

[0040] Example 2:

[0041] Please see Figure 1-4 This utility model provides a bending device for machine frame sheet metal parts, comprising:

[0042] Mounting base 1 and support frame 2;

[0043] Two arc-shaped plates 3 are respectively set on both sides of the upper end of the mounting base 1, and the support frame 2 is set on the upper end of the mounting base 1. Two limiting plates 4 are rotatably connected between the two arc-shaped plates 3.

[0044] Two adjusting plates 5 are respectively set on one side of the two limiting plates 4. A rectangular groove is opened in the mounting base 1. A threaded rod 6 is rotatably connected in the rectangular groove. The external threads on both sides of the threaded rod 6 are arranged in opposite directions.

[0045] Mounting frame 7 is located inside the upper part of support frame 2. Mounting frame 7 is U-shaped and is rotatably connected to positioning column 8 inside. Multiple upper modules 9 are provided on the outside of positioning column 8, and the size of the multiple upper modules 9 is set in an increasing manner.

[0046] Specifically, such as Figure 3 As shown, both arc-shaped plates 3 are provided with arc-shaped grooves, and both sides of the two limiting plates 4 are provided with fixing screws 20 that are adapted to the arc-shaped grooves. The two fixing screws 20 located on both sides are respectively provided with the two arc-shaped grooves on both sides and are provided with fixing nuts 21. The two fixing nuts 21 on both sides are respectively abutted against one side of the two arc-shaped plates 3.

[0047] Through its design, the fixing screws 20 and fixing nuts 21 on both sides of the two limiting plates 4 can stably lock their angles after the angles of the two limiting plates 4 are adjusted, so as to prevent the angles from shifting when the frame sheet metal parts are bent, thereby ensuring the quality of bending the frame sheet metal parts.

[0048] See Figure 1-4When bending the frame sheet metal parts using a bending device, the angle of the two limit plates 4 needs to be adjusted according to the required bending angle. To adjust the angle, the servo motor 12 needs to be started. The output end of the servo motor 12 will drive the threaded rod 6 to rotate. The threaded rod 6 will drive the sliding plates 11 and the adjusting plate 5 on both sides to move in opposite directions. Thus, the two limit plates 4 can be rotated by the two limit rods 10, thereby adjusting the included angle between the two limit plates 4. Then, by rotating the two fixing nuts 21 on both sides, the angle of the two limit plates 4 can be fixed. Next, rotate the positioning column 8 to rotate the upper module 9 of the corresponding size to the bottom. During the bending process, the frame sheet metal parts need to be placed on the upper end of the two limit plates 4. Then, start the electric push rod 17. The output end of the electric push rod 17 will drive the mounting frame 7 and the upper module 9 to move downward. With the help of the two limit plates 4, the frame sheet metal parts can be bent to the required angle.
