Technical Field
[0001] This utility model relates to the field of electrical control cabinet processing technology, and in particular to a wire C-shaped bending device. Background Technology
[0002] Wires are essential components in electrical control cabinets for connecting control switches and other devices. Wires used to connect control switches arranged in the same row are often bent into a concave shape. Currently, most bending is done manually with pliers. This bending method is difficult to control in terms of precision, which affects the wire insertion operation. Secondly, it is not easy to bend wires with larger diameters. Furthermore, bending with pliers is inefficient. Utility Model Content
[0003] This utility model provides a C-shaped bending device for wires to solve the shortcomings of the prior art, namely the low bending efficiency and poor bending accuracy of C-shaped wires, and has strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A wire C-shaped bending device includes a rectangular base plate with a pair of strip holes. Bending mechanisms are movably installed at both ends of the strip holes. The bending mechanisms are used to bend multiple wires into a C-shaped structure.
[0005] Furthermore, the bending mechanism includes a rotating seat fixed to the lower wall end of the base plate by screws. A lead screw is rotatably mounted on the rotating seat. An end cap with a diameter larger than the outer diameter of the lead screw is provided on the outer end of the lead screw. A limit ring is fixed on the lead screw by a pin. The end cap is located on the outer side of the rotating seat, and the limit ring is located on the inner side of the rotating seat. A movable seat is threadedly connected to the lead screw. A connecting plate is provided on the upper end of the movable seat. A movable plate is welded to the other end of the connecting plate. Multiple movable rods are threadedly connected to the movable plate. The movable rods pass through the slotted holes. A movable upper plate is threadedly connected to the upper end of the movable rods. The movable upper plate is located on the upper side of the base plate. A waist-shaped hole and a rectangular hole are passed through the movable upper plate and the movable plate from top to bottom. The length direction of the waist-shaped hole is perpendicular to the length direction of the slotted hole, and the length direction of the rectangular hole is parallel to the length direction of the waist-shaped hole. A window with a length direction perpendicular to the length direction of the slotted hole is opened on the base plate.
[0006] Furthermore, end plates are fixed to both ends of the moving plate along its length by screws, and a pair of guide rods are provided between the end plates. A cylinder is fixed to one of the end plates by screws, and a push plate is fixed to the movable end of the cylinder by a nut at the end of its push rod through a thread. The two ends of the push plate are respectively sleeved on the guide rod. One end of the movable upper plate is welded with an L-shaped molded plate. An inner rod is movably installed in the waist-shaped hole and passes through the window. A push arm is fixed to the lower end of the inner rod. The length direction of the push arm is parallel to the length direction of the waist-shaped hole. The other end of the push arm is fixed to the inner wall of the push plate. The push arm is located on the lower side of the movable plate. A pressure sleeve is rotatably installed at the upper end of the inner rod. A limit nut is threadedly connected to the upper end of the inner rod. The limit nut limits the upper end of the pressure sleeve, and the pressure sleeve is located on the outside of the molded plate.
[0007] Furthermore, multiple L-shaped arc grooves with a semi-circular cross-section are formed on the inner side of the molded plate.
[0008] Furthermore, a lower extension plate is movably provided within the rectangular hole. A T-shaped seat is fixed to the lower end of the lower extension plate by screws. The T-shaped seat is located below the movable plate. A pair of movable through rods are passed through the T-shaped seat. The outer ends of the movable through rods can be passed through the end plate. An inner top plate is welded to the inner end of the movable through rod. A first spring is sleeved on the movable through rod. The inner end of the first spring abuts against the inner wall of the inner top plate. The other end of the first spring abuts against the T-shaped seat. A pressure plate is welded to the upper end of the lower extension plate. A pair of pull rods are threadedly connected to the pressure plate. The other end of the pull rod is formed with an end head. A fixed vertical plate is sleeved on the pull rod. The fixed vertical plate is fixed to the movable upper plate by screws. A second spring is sleeved on the pull rod. One end of the second spring abuts against the end head. The other end of the second spring abuts against the outer wall of the fixed vertical plate.
[0009] Furthermore, a constraint groove matching the arc groove is provided on the inner wall of the pressure plate.
[0010] The advantages of the above technical solution are: This invention firstly allows for adjustment of the inflection point of the wire bend as needed, thereby improving its applicability.
[0011] Secondly, when bending the wire, the present invention first uses a pressure plate and a forming plate to stably constrain the wire, and then uses the movement of the pressure sleeve to bend the wire. During the bending process, since the pressure sleeve can rotate, it can avoid the pressure sleeve squeezing the wire and causing damage to the outer sheath of the wire. Attached Figure Description

[0017] The two ends of the movable plate 25 are respectively fixed with end plates 28 by screws. A pair of guide rods 29 are provided between the end plates 28. A cylinder 30 is fixed on one of the end plates 28 by screws. The movable end of the cylinder 30 is connected to the nut at the end of its push rod by a thread and a push plate 31 is fixed thereon. The two ends of the push plate 31 are respectively sleeved on the guide rod 29. One end of the movable upper plate 39 is welded with an L-shaped forming plate 42. An inner rod 33 is movably installed inside the oblong hole 40, passing through the window 11. A push arm 32 is fixed to the lower end of the inner rod 33, and the length direction of the push arm 32 is parallel to the length direction of the oblong hole 40. The other end of the push arm 32 is fixed to the inner wall of the push plate 31. The push arm 32 is located on the lower side of the movable plate 25. A pressure sleeve 49 is rotatably installed at the upper end of the inner rod 33. A limit nut 48 is threadedly connected to the upper end of the inner rod 33, limiting the upper end of the pressure sleeve 49, which is located on the outer side of the forming plate 42. Multiple L-shaped arc grooves 43 with a semi-circular cross-section are opened on the inner side of the forming plate 42. A lower extension plate 34 is movably disposed within the rectangular hole 41. A T-shaped seat 35 is fixed to the lower end of the lower extension plate 34 by screws. The T-shaped seat 35 is located below the movable plate 25. A pair of movable through rods 36 pass through the T-shaped seat 35. The outer ends of the movable through rods 36 can pass through the end plate 28. An inner top plate 38 is welded to the inner end of the movable through rods 36. A first spring 37 is sleeved on the movable through rods 36. The inner end of the first spring 37 abuts against the inner wall of the inner top plate 38. The other end of spring 37 abuts against T-shaped seat 35. A pressure plate 47 is welded to the upper end of lower extension plate 34. A pair of pull rods 45 are threaded onto pressure plate 47.

[0018] In this embodiment, the wire is first cut into several segments of equal length as needed, and the outer sheath of the wire needs to be removed during the cutting process.
[0019] Then, the operator rotates the end cap 21 according to the bending point of the wire. When the end cap 21 rotates, it will drive the lead screw 20 to rotate. When the lead screw 20 rotates, it will drive the moving seat 23 to move along the length of the strip hole 10 until the distance between the pressure sleeves 49 is equal to the required distance.
[0020] Next, the operator places the wire into each arc groove 43, ensuring that both ends of the wire extend equal lengths beyond the forming plate 42. Simultaneously, the cylinder 30 is activated, moving the push plate 31. This movement causes the push arm 32 to move the pressure sleeve 49 towards the forming plate 42. Simultaneously, the push plate 31 acts on the inner top plate 38, bringing the pressure plate 47 closer to the forming plate 42. The constraint groove on the pressure plate 47 then constrains the wire. Afterward, the pressure plate 47 stops moving, and the push plate 31 compresses the first spring 37. During this compression, the pressure sleeve 49 acts on the wire, working with the forming plate 42 to bend the wire into a C-shape. After bending, the pressure sleeve 49 and pressure plate 47 return to their positions, ready for another bending operation.
[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
