Description

Technical Field

[0001] The utility model relates to the technical field of wire processing equipment, and more specifically, to a multi-direction wire bending device. Background Art

[0002] Wire is the one with the smallest cross-sectional size among hot-rolled steel sections. In China, hot-rolled round steel with a diameter of 5 - 9 mm in a total of eight specifications supplied in coils is called wire. Since wire is delivered in coils, it is also called wire rod. The concept of wire abroad is slightly different from that in China. In addition to the circular cross-section, there are also other shapes, and its diameter varies due to different demand situations and production technology levels.

[0003] There is a wire bending device with the publication number of CN208853607U. It drives a bending part to move towards a fixing device through a driving device, so that the bending part can bend the wire on the fixing device. The structure is simple and the operation is convenient. However, there are still deficiencies. It can only bend the wire in one direction. But when the wire is in use, in order to be convenient for use, it is inevitable to have bends in multiple directions. Therefore, bending in one direction is difficult to meet the need for multi-direction bending. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-direction wire bending device, which solves the problem that in actual use, the wire bending device with the publication number of CN208853607U mentioned in the above background art can only bend the wire in one direction. But when the wire is in use, in order to be convenient for use, it is inevitable to have bends in multiple directions.

A fixing block is rotatably connected to the upper surface of the bottom plate. A wire groove is opened in the fixing block. A fixing structure matching the wire groove is arranged on the fixing block. The output shaft of the rotating motor passes through an avoidance hole opened on the bottom plate and is connected to the fixing block. A bending mechanism is arranged on one side of the upper surface of the bottom plate. The bending mechanism includes a vertical plate movably connected to the bottom plate. An installation groove is opened on the side of the vertical plate close to the fixing block. A lead screw is arranged in the installation groove. The upper and lower ends of the lead screw are connected to the upper and lower walls of the installation groove through bearings. A driving motor is fixedly connected to the upper end of the vertical plate. The output shaft of the driving motor passes through an avoidance hole opened on the vertical plate and is connected to the lead screw.

[0016] Figure 2 is a schematic diagram of a partially enlarged structure at A in an embodiment of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] It is easy to understand that according to the technical solution of the present utility model, without changing the essence of the present utility model, those of ordinary skill in the art can propose various structural ways and implementation ways that can be mutually replaced. Therefore, the following detailed description and the drawings are only illustrative of the technical solution of the present utility model, and should not be regarded as all of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0018] The following will be combined with the specification appendixFigure 1-2 And the above technical solutions will be described in detail with specific embodiments:

[0019] A multi-directional wire bending device provided by the utility model includes a bottom plate 1. A plurality of symmetrically arranged support rods 2 are arranged below the bottom plate 1. A rotating motor 3 is fixedly connected to the lower surface of the bottom plate 1. A fixed block 4 is rotatably connected to the upper surface of the bottom plate 1. A wire groove 5 is opened in the fixed block 4. A fixing structure matching the wire groove 5 is arranged on the fixed block 4. The output shaft of the rotating motor 3 passes through an avoidance hole opened in the bottom plate 1 and is connected to the fixed block 4. A bending mechanism is arranged on one side of the upper surface of the bottom plate 1. The bending mechanism includes a vertical plate 6 movably connected to the bottom plate 1. An installation groove 7 is opened on the side of the vertical plate 6 close to the fixed block 4. A lead screw 8 is arranged in the installation groove 7. The upper and lower ends of the lead screw 8 are connected to the upper and lower walls of the installation groove 7 through bearings. A driving motor 9 is fixedly connected to the upper end of the vertical plate 6. The output shaft of the driving motor 9 passes through an avoidance hole opened in the vertical plate 6 and is connected to the lead screw 8. A cross bar 10 threadedly connected to the outside of the lead screw 8 and slidably connected to the installation groove 7 is arranged at one end of the cross bar 10 close to the fixed block 4. A bending member 11 is arranged at one end of the cross bar 10 close to the fixed block 4. A pushing assembly is arranged on the side of the vertical plate 6 away from the fixed block 4.

[0020] When bending the wire, the lower end of the wire is placed in the wire groove 5 on the fixed block 4 and the wire is fixed in the wire groove 5 through the fixing structure. Subsequently, the pushing assembly starts to work, thereby driving the bending mechanism to move towards the fixed block 4 until the cross bar 10 drives the bending member 11 to move until the wire is bent. After the bending work is completed, the pushing assembly drives the bending mechanism to reset. As a preference, the initial height of the bending member 11 is flush with the height of the fixed block 4, that is, the lower surface of the bending member 11 and the upper surface of the fixed block 4 are on the same horizontal plane. When it is necessary to bend other positions of the wire in other directions, the rotating motor 3 works, thereby driving the fixed block 4 and the wire to rotate. When the wire rotates to the required direction, the rotating motor 3 stops working. Subsequently, the driving motor 9 works to drive the lead screw 8 to rotate. Since the cross bar 10 threadedly connected to the lead screw 8 is slidably connected to the installation groove 7, the cross bar 10 and the bending member 11 can move upward with the rotation of the lead screw 8. After the bending member 11 moves to the required height of the wire, the driving motor 9 stops working. Subsequently, the pushing assembly works to drive the bending mechanism to move, thereby bending the wire. The above operations can be repeated to achieve multi-directional bending operations on the wire.

[0021] In order to facilitate wire bending, as a preferred embodiment, the notch of the wire groove 5 is chamfered.

[0022] As a preferred embodiment, the fixing structure includes a sliding hole 12 which is opened on the inner wall of one side of the wire groove 5 and penetrates through the fixing block 4 to communicate with the outside. A pull rod 13 is slidably connected in the sliding hole 12. The two ends of the pull rod 13 are respectively located outside the fixing block 4 and inside the wire groove 5. The inner end of the pull rod 13 is fixedly connected with a clamping plate 14. A spring 15 is fixedly connected between the surface of the clamping plate 14 close to the pull rod 13 and the wire groove 5. The spring 15 is sleeved on the pull rod 13. When fixing the wire, pull the pull rod 13 outwards. Preferably, the clamping plate 14 is in close contact with the inner wall of the wire groove 5 in the initial state. At this time, the spring 15 is in a compressed state. Through the pull rod 13, the clamping plate 14 is moved away from the inner wall of the wire groove 5. Then, insert the wire between the wire groove 5 and the clamping plate 14. Then release the pull rod 13. At this time, the spring 15 is still in a compressed state. Under the action of elastic potential energy, the wire can be clamped and fixed between the clamping plate 14 and the wire groove 5.

[0023] In order to enhance the fixing effect by strengthening the friction force, as a preferred embodiment, a rubber layer 16 is fixedly connected to the side of the clamping plate 14 away from the pull rod 13.

[0024] In order to further enhance the fixing effect, as a preferred embodiment, the rubber layer 16 is arranged in a sawtooth shape.

[0025] In order to facilitate grasping the height of the bending part 11 and the rotation angle of the fixing block 4 and the wire, as a preferred embodiment, a vertical scale line is provided on the vertical plate 6, and a circular scale line arranged on the bottom plate 1 is provided around the outside of the fixing block 4.

[0026] As a preferred embodiment, the pushing component is a hydraulic push rod 17, and the end of the hydraulic push rod 17 is fixedly connected to the vertical plate 6.

[0027] As a preferred embodiment, a wheel groove 18 is opened on the bottom plate 1, and a roller 19 is arranged at the lower end of the vertical plate 6. The roller 19 slides in the wheel groove 18. By providing the roller 19 and the wheel groove 18, the friction force when the vertical plate 6 moves can be reduced to facilitate its movement.

[0028] The motors and hydraulic push rods mentioned above are mature existing technologies, so their principles and structures will not be elaborated here. The models and specifications of the motors and hydraulic push rods can be selected according to the actual situation, and the circuit connection is defaultly connected to the municipal circuit.
