Technical Field

[0001] This invention relates to bending technology, and more particularly to an automatic bending device for electrical distribution box bodies. Background Technology

[0002] Bending equipment is a machine designed for bending thin sheet materials, shaping them into the required bending effect. During the production and processing of sheet materials, it is often necessary to bend the sheet materials into different sections at a certain angle to accommodate subsequent assembly or gluing processes.

[0003] Because the structure of the distribution box requires stamping and bending according to the actual installation environment, the stamping parts in the stamping equipment need to have their angles adjusted according to the actual structure being produced, in order to produce products with high precision. Therefore, a bending machine that can adjust the pressing angle of the stamping parts according to actual needs is required. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention proposes an automatic bending device for distribution box bodies.

[0005] The technical solution of this invention is implemented as follows: An automatic bending device for a distribution box body, characterized in that it comprises: A fixed frame is provided, with symmetrical conveyor platforms in the middle of the frame. A base is provided between the conveyor platforms, and a stamping cylinder is provided at the upper end of the base. The stamping cylinder is mounted on the fixed frame. A stamping mechanism is located at the lower end of the stamping cylinder. The stamping mechanism includes a pressure-applying component, a stamping component, and an adjusting assembly for connecting the stamping component to the pressure-applying component. The adjusting assembly changes the installation angle between the stamping component and the pressure-applying component. The pressure-applying component consists of a pressure-applying part and a mounting part. The pressure-applying part is connected to the stamping cylinder. The length of the mounting part is shorter than the length of the pressure-applying part. A mounting hole is provided in the middle of the mounting part, and a mounting shaft is provided in the mounting hole. The stamped part consists of a stamping section and fixing sections at both ends of the stamping section. The fixing section has a through hole in the middle that mates with a mounting shaft. The fixing sections together form a mounting area for the pressure-applying component. The adjusting assembly includes a fixed base, an adjusting component, a limiting component, and a rotating component. The fixed base has a through hole and a positioning hole. The inner wall of the positioning hole has a first tooth. The adjusting component consists of a hexagonal block, a push rod, and a threaded rod. The inner diameter of the through hole matches the diameter of the push rod. The limiting component is installed inside the positioning hole. The rotating component is installed in the middle of the limiting component. The limiting component has multiple elastic arms. The outer wall of each elastic arm has a second tooth that mates with the first tooth. The rotating component has multiple pushing parts that mate with the elastic arms. A spring is provided between the limiting components. The pushing part contacts the inner wall of the elastic arm. When the rotating component rotates, it compresses the spring and pushes the elastic arm to open outward, maintaining the engagement of the second tooth with the first tooth. A movable hole is provided in the middle of the rotating component. A guide groove is provided on the inner wall of the movable hole. A pressure plate and an elastic component are provided in the movable hole. Threaded holes and symmetrically arranged positioning rods are provided at both ends of the mounting shaft. The pressure plate is mounted on the positioning rods. The threaded rods pass through the pressure plate and connect to the threaded holes. A guide protrusion that mates with the guide groove is provided on the outer wall of the pressure plate. Rotating the adjusting component pushes the pressure plate with the push rod, compressing the elastic component. The elastic component moves within the guide groove through the guide protrusion, maintaining the deflection angle of the rotating component and pushing the second tooth on the elastic arm to mesh with the first tooth.

[0006] In this invention, the mounting shaft is provided with multiple limiting grooves, and the inner wall of the mounting hole is provided with a limiting block that cooperates with the limiting groove.

[0007] In this invention, the guide groove consists of a vertical section and a spiral section.

[0008] In this invention, the limiting member is provided with a blocking part, the blocking part is provided with a blocking surface, the blocking surface is in contact with one end of the spring, and the elastic arm is connected to the blocking part through an arc-shaped part.

[0009] In this invention, the limiting member has a circular hole in the middle, and a plurality of first limiting blocks are provided in the circular hole. The first limiting blocks are disposed on the blocking part, and the mounting shaft is provided with a first limiting port that cooperates with the first limiting blocks.

[0010] In this invention, the rotating member is provided with a clearance opening that cooperates with the blocking part.

[0011] In this invention, the rotating component is provided with a second limiting block, and the mounting shaft is provided with a second limiting port that cooperates with the second limiting block.

[0013] In this invention, the pushing part is provided with a pushing protrusion, which is placed inside the recess.

[0014] The automatic bending device for distribution box bodies according to this invention has the following advantages: The pressing component and the stamping component in this automatic bending device are installed using an adjustable structure. When it is necessary to adjust the angle between the stamping component and the pressing component, simply rotate the adjusting component in the adjusting assembly. This keeps the elastic component pushing the pressing plate, causing the rotating component to rotate, so that the elastic arm no longer limits the first tooth on the fixed seat, thus adjusting the angle between the stamping component and the pressing component. The stamping forming of the sheet metal can be adjusted according to different distribution box structures. Not only is the adjustment simple and the operation convenient, but the stability between the stamping component and the pressing component is also improved. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] like Figures 1 to 17 As shown, this automatic bending device for a distribution box includes a fixed frame 1 and a stamping mechanism 2. The stamping mechanism 2 is mounted on the fixed frame 1, and the fixed frame 1 keeps the stamping mechanism 2 stable. The stamping mechanism 2 is used to stamp and bend the sheet metal at the lower end.

[0019] A symmetrical conveyor platform 3 is provided in the middle of the fixed frame 1, and a base 4 is provided between the conveyor platforms 3. A stamping cylinder 5 is provided at the upper end of the base 4 and is mounted on the fixed frame 1.

[0020] The stamping mechanism 2 is located at the lower end of the stamping cylinder 5. The stamping mechanism 2 includes a pressure applying element 6, a stamping element 7, and an adjusting component 8 for connecting the stamping element 7 to the pressure applying element 6. The adjusting component 8 changes the installation angle between the stamping element 7 and the pressure applying element 6. By rotating the adjusting component 9, the adjusting component 9 can push the pressure plate 11, thereby compressing the elastic element 10, causing the guide protrusion 12 to move along the guide groove 13. However, since the position of the guide protrusion 12 is limited by the positioning rod 14, the angle will not deflect. The rotating component 34, along the trajectory of the guide groove 13, will cause it to deflect at a certain angle, thereby pushing the elastic arm 17 through the pushing protrusion 16 on the pushing part 15, thereby causing the second tooth 18 to mesh with the first tooth 19, realizing that the mounting shaft 20 restricts the position of the stamping element 7. By adjusting the preset angle, the stamping of the sheet metal can be achieved.

[0021] The pressure-applying component 6 consists of a pressure-applying part 21 and a mounting part 22. The pressure-applying part 21 is connected to the stamping cylinder 5. The length of the mounting part 22 is less than the length of the pressure-applying part 21. A mounting hole 23 is provided in the middle of the mounting part 22, and a mounting shaft 20 is provided inside the mounting hole 23. The mounting shaft 20 is provided with multiple limiting grooves 24, and a limiting block 25 that mates with the limiting grooves 24 is provided on the inner wall of the mounting hole 23. This ensures that the mounting shaft 20 and the pressure-applying component 6 maintain a fixed angle, preventing the angle of the mounting shaft 20 from deflecting, thereby maintaining the angle of the stamped component 7 by the mounting shaft 20.

[0022] Both ends of the mounting shaft 20 are provided with annular extensions 26, and a cavity 27 is formed in the middle of the annular extensions 26. One end of the elastic member 10 is placed in the cavity 27.

[0023] The stamped part 7 consists of a stamping portion 28 and fixing portions 29 located at both ends of the stamping portion 28. A through hole 30, which mates with the mounting shaft 20, is provided in the middle of the fixing portion 29. An mounting area 31 for mounting the pressure-applying member 6 is formed between the fixing portions 29 and the fixing portion 29. The fixing seat 32 can be bolted onto the stamped part 7, so that when the angle of the fixing seat 32 changes, the angle of the stamped part 7 also changes accordingly.

[0024] The adjustment assembly 8 includes a fixed base 32, an adjusting member 9, a limiting member 33, and a rotating member 34. The adjusting member 9 passes through the fixed base 32, the adjusting member 9, and the limiting member 33 and is connected to the mounting shaft 20. The limiting member 33 is installed in the middle of the fixed base 32, while the rotating member 34 is installed in the middle of the limiting member 33, but at a position between the fixed base 32 and the limiting member 33. The fixed base 32 is provided with a through hole 35 and a positioning hole 36. The inner wall of the positioning hole 36 is provided with a first tooth 19.

[0025] The adjusting component 9 consists of a hexagonal block 37, a push rod 38, and a threaded rod 39. The inner diameter of the through hole 35 matches the diameter of the push rod 38, allowing the push rod 38 to move within the through hole 35.

[0026] A limiting member 33 is installed inside a positioning hole 36, and a rotating member 34 is installed in the middle of the limiting member 33. The limiting member 33 has multiple elastic arms 17, which are connected to a blocking part 41 via an arc-shaped portion 40. An elastic opening 42 is formed in the middle of the arc-shaped portion 40. The outer wall of the elastic arm 17 has a second tooth 18 that engages with the first tooth 19. When the elastic arm 17 is pushed, the second tooth 18 remains engaged with the first tooth 19, providing a limiting position. The inner wall of the elastic arm 17 forms a sliding surface 43 for engaging with the pushing protrusion 16.

[0027] The limiting member 33 is provided with a blocking part 41, and the blocking part 41 is provided with a blocking surface 44, which contacts one end of the spring 45. The limiting member 33 is provided with a circular hole 46 in the middle, and multiple first limiting blocks 61 are provided in the circular hole 46. The first limiting blocks 61 are provided on the blocking part 41. The mounting shaft 20 is provided with a first limiting port 47 that cooperates with the first limiting blocks 61. The first limiting port 47 is located on the annular extension 26.

[0028] The rotating member 34 is provided with a clearance opening 48 that mates with the blocking part 41. The rotating member 34 is provided with multiple pushing parts 15 that mate with the elastic arm 17. Each pushing part 15 has a pushing protrusion 16, which is positioned within a recess 49. The pushing protrusion 16 has rounded corners to facilitate sliding with the sliding surface 43 on the elastic arm 17. The pushing part 15 is also provided with a pushing surface 50.

[0029] The rotating component 34 is provided with a second limiting block 25, and the mounting shaft 20 is provided with a second limiting port 51 that cooperates with the second limiting block 25. The second limiting port 51 is located on the annular extension 26.

[0030] A spring 45 is provided between the pushing part 15 and the limiting member 33. The pushing part 15 is in contact with the inner wall of the elastic arm 17. When the rotating member 34 rotates, it compresses the spring 45 and pushes the elastic arm 17 to open outward, keeping the second tooth 18 engaged with the first tooth 19. One end of the spring 45 is in contact with the blocking surface 44, and the other end is in contact with the pushing surface 50.

[0031] The rotating component 34 has a movable hole 52 in the middle, and a guide groove 13 is provided on the inner wall of the movable hole 52. The guide groove 13 is composed of a vertical section 53 and a spiral section 54. When the first tooth 19 and the second tooth 18 are not engaged, the guide protrusion 12 is located in the vertical section 53. When the first tooth 19 and the second tooth 18 are engaged, the guide protrusion 12 can be kept in the spiral section 54.

[0032] The movable hole 52 is provided with a pressure plate 11 and an elastic element 10. One end of the elastic element 10 is in contact with the pressure plate 11, and the other end is in contact with the mounting shaft 20.

[0033] Threaded holes 55 and symmetrically arranged positioning rods 14 are provided at both ends of the mounting shaft 20. A pressure plate 11 is mounted on the positioning rods 14, and a moving hole 60 that mates with the positioning rods 14 is provided on the pressure plate 11. A retaining hole 56 is provided in the middle of the pressure plate 11. The diameter of the retaining hole 56 matches the diameter of the threaded rod 39, but is smaller than the diameter of the push rod 38, allowing the push rod 38 to push the pressure plate 11 to compress the elastic element 10. The threaded rod 39 passes through the pressure plate 11 and connects to the threaded hole 55. A guide protrusion 12 that mates with the guide groove 13 is provided on the outer wall of the pressure plate 11.

[0034] Rotating the adjusting component 9, the push rod 38 pushes the pressure plate 11, compressing the elastic component 10, which moves within the guide groove 13 via the guide protrusion 12, maintaining the deflection angle of the rotating component 34, and pushing the second tooth 18 on the elastic arm 17 to mesh with the first tooth 19.

[0035] Furthermore, the limiting member 33 is provided with a bearing portion 57, the bearing portion 57 is provided with a blocking protrusion 58, and the elastic arm 17 is provided with a notch 49 that mates with the blocking protrusion 58. The rotating member 34 is provided on the bearing portion 57 and can rotate on the bearing portion 57.

[0036] Under the action of the blocking protrusion 58, the elastic arm 17 has gaps 59 between itself and the blocking part 41, between itself and the bearing part 57, and between itself and the arc-shaped part 40.

[0037] When the adjusting component 8 is installed, to adjust the angle of the stamping part 7, the adjusting component 9 can be loosened first, so that the threaded rod 39 rotates in the threaded hole 55. At this time, the adjusting component 9 no longer applies pressure to the elastic component 10, and the elastic component 10 will push the pressure plate 11 to move towards the hexagonal block 37, thereby causing the spring 45 to push the pushing part 15, causing the rotating part 34 to rotate, gradually causing the guide protrusion 12 to move from the spiral section 54 to the vertical section 53. Keep the spring 45 in its reset position, and at the same time, the elastic arm 17 is no longer pushed by the pushing protrusion 16, thereby causing the first tooth 19 to separate from the second tooth 18. Then the stamping part 7 can be rotated to adjust the angle between the stamping part 7 and the pressure component 6, so that the sheet metal can be stamped and bent at different angles.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
