Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, and more specifically to a bending machine for a low-voltage distribution box. Background Art

[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base consists of a base shell, a coil and a cover plate. The coil is placed in the depression of the base shell, and the top of the depression is covered with a cover plate. When in use, the coil is energized by a wire, and after energization, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and can process workpieces with side walls, and the operation is also very simple.

[0003] However, the current bending machines have the following problems:

[0004] The bending machines in daily life often have complex structures, occupy a large area, can only perform 90-degree bending operations, and cannot adjust the bending angle according to the actual objects being processed, which brings great trouble to users. Utility Model Content

[0005] 1. Technical problems to be solved:

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a bending machine for a low-voltage distribution box, which places a thin plate to be bent between the gap between the base and the pressure plate, and the rear end of the thin plate abuts against the upper side of the limiter to limit the horizontal position and the front and rear position of the thin plate to prevent displacement and uneven bending surface. The coil is then energized by a wire, which causes the pressure plate to generate gravity after power-on, thereby achieving the clamping and limitation of the thin plate between the pressure plate and the base. Finally, a person bends the clamped thin plate by rotating the connecting rod. At the same time, during the rotation of the connecting rod, the angle and position of the bending of the thin plate can be limited by the action of the angle recognition component, which prompts the person to adjust the bending angle of the thin plate to any position when bending the thin plate, thereby providing great convenience for the thin plate bending operation.

[0030] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0031] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", "provided on" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0034] See also Figure 1-4 A bending machine for a low-voltage distribution box comprises a supporting column 1, an electric box 2 is installed on the upper end of the supporting column 1, a base 3 is fixedly connected to the upper end of the electric box 2, a front side section of the base 3 is movably connected to a bending member 4 through a hinge, two symmetrically distributed connecting rods 5 are fixedly connected to the bottom end of the bending member 4, an angle recognition component 6 is installed between the side walls of the electric box 2 and the bending member 4, a supporting plate 7 is fixedly connected to the rear side end of the base 3, and limiting members 8 are installed on the left and right sides of the supporting plate 7, and a pressing plate 9 is provided at the upper end of the base 3.

[0035] During the use of this scheme, in order to avoid the phenomenon that the existing bending machine can only perform 90-degree bending operations but cannot adjust the bending angle according to the actual processed objects, in this embodiment, the thin plate to be bent is first placed between the gap between the base 3 and the pressure plate 9, and the rear end of the thin plate is against the upper side of the limiter 8 to limit the horizontal position and front and rear position of the thin plate to prevent displacement and uneven bending surface. Then, the coil is energized by the wire, which causes the pressure plate 9 to generate attraction after power-on, thereby achieving the clamping and limitation of the thin plate between the pressure plate 9 and the base 3. Finally, the personnel bends the clamped thin plate by rotating the connecting rod 5. At the same time, during the rotation of the connecting rod 5, the angle and position of the thin plate can be limited under the action of the angle recognition component 6, which prompts the personnel to adjust the bending angle of the thin plate to any position when bending the thin plate, thereby providing great convenience for the thin plate bending operation.

[0036] See also Figure 1-2 The angle identification component 6 includes a connecting plate 61 fixedly connected to the side end of the electrical box 2, a guide hole 62 is opened at the side end of the connecting plate 61, and a receiving groove 63 is opened on the bottom wall of the guide hole 62. A transmission box 65 is installed on the side end of the connecting plate 61, and a plurality of arc-shaped limit plates 64 are rotatably connected between the inner walls of the receiving groove 63. The transmission shaft of the limit plate 64 passes through the interior of the transmission box 65. The transmission shafts of the plurality of limit plates 64 are uniformly connected by a transmission chain, and a motor 66 is installed at the outer end of the transmission shaft of one of the limit plates 64. A spring is fixedly connected between the limit plate 64 and the bottom wall of the receiving groove 63. The rear end of the bending member 4 is fixedly connected to a connecting block 2 41, and the side end of the connecting block 2 41 is rotatably connected to a rotating shaft 42, and the rotating shaft 42 is located between the inner walls of the guide hole 62.

[0037] During the use of this solution, when a person rotates the bending member 4 to bend a thin plate, the second connecting block 41 drives the rotating shaft 42 to slide counterclockwise between the inner walls of the guide hole 62 during the rotation of the bending member 4. At the same time, every time the rotating shaft 42 slides an angle value, the rotating shaft 42 presses the limiting plate 64, so that the limiting plate 64 squeezes the spring under pressure and is received between the inner walls of the receiving groove 63.

[0038] Then, when the rotating shaft 42 slides to one side of the limiting plate 64, the limiting plate 64 rebounds under the action of the spring return and is located between the inner walls of the guide hole 62 again, so that the position of the bending member 4 is limited and cannot rotate clockwise, and the bending angle of the thin plate is maintained at this time;

[0039] Finally, since the transmission of multiple limit plates 64 is uniformly driven and transmitted by the chain, when personnel need to reset the bending part 4 to restore its original shape later, they can drive the output end of the motor 66 clockwise to rotate, thereby driving the transmission shaft of a limit plate 64 to rotate synchronously, and press the spring, so that the limit plates 64 can be uniformly rotated and stored in the storage groove 63, so that the rotating shaft 42 can slide to the bottom side of the guide hole 62 again for subsequent bending operations.

[0040] In the present embodiment, each time the rotating shaft 42 slides against a limit plate 64, the limit plate 64 pops up only when the rotating shaft 42 slides over one side of the limit plate 64. At this time, the bending part 4 rotates at a scale value, that is, 10°, 20° or even 90°.

[0041] See also Figure 2 The side end of the connecting plate 61 is engraved with an angle mark, and the angle mark is located on the upper side of the guide hole 62.

[0042] During use of the present invention, by setting angle markings, personnel can more clearly know the bending angle at the time when bending a thin plate, which is beneficial for personnel's observation.

[0043] See also Figure 1 and Figure 3-4 The limiting member 8 includes two support rods 81 fixedly connected to the rear end of the base 3, and the two support rods 81 are respectively located on the left and right sides of the supporting plate 7. The outer ends of the support rods 81 are sleeved with a jacket 82, and the upper end of the jacket 82 is fixedly connected with a connecting block 83. The side end of the connecting block 83 is provided with a through hole 84, and a screw 85 is inserted between the inner walls of the through hole 84.

[0044] During use of the present solution, personnel can adjust the position of the jacket 82 on the surface of the support rod 81 according to the length of the thin plate, until it is adjusted to a position that contacts the rear side of the thin plate. Then, personnel insert the screw 85 from the through hole 84 and, by locking the nut, cause the connecting blocks 83 on both sides to contract inward, so that the jacket 82 is positioned on the surface of the support rod 81. Subsequently, personnel can contact the thin plate against one side of the connecting block 83 to align and limit it.

[0045] See also Figure 1 and Figure 3-4 A threaded hole is formed at the rear end of the support rod 81.

[0046] During use of this solution, if the size of the thin plate to be bent is too long, the personnel can connect another support rod 81 to the rear end of the support rod 81, and connect the threaded end of the other support rod 81 to the threaded hole to facilitate the extension of the length of the support rod 81.

[0047] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
