Description

Technical Field

[0001] The present application relates to the technical field of bending machines, and in particular to a flat wire bending mechanism. Background Art

[0002] Bending equipment is mechanical equipment used to bend metal sheets in the metal processing industry. The bending equipment can meet the bending requirements of different shapes and angles, and is widely used in fields such as sheet metal processing, machinery manufacturing, and architectural decoration.

[0003] According to different bending methods, the bending mechanism can also be divided into two-dimensional bending machines and three-dimensional bending machines, etc. The two-dimensional bending machine mainly realizes the bending processing of wire in a plane. The existing two-dimensional bending mechanism usually includes a workbench, a clamping assembly for clamping the wire, and a rotating assembly. The clamping assembly includes a fixed block and a sliding block, and the sliding block is slidably installed on the workbench through a linear drive mechanism. The rotating assembly has a positioning block for positioning the wire.

[0004] In view of the above related technologies, when using the above bending mechanism for bending, each clamping requires starting the linear drive mechanism, resulting in a long overall bending time and low efficiency. Summary of the Utility Model

[0005] In order to facilitate the positioning of the wire and improve the bending efficiency, the present application provides a flat wire bending mechanism.

[0006] The flat wire bending mechanism provided by the present application adopts the following technical solutions:

[0007] A flat wire bending mechanism includes a work plate and a rotating assembly. The rotating assembly has at least one positioning pin for bending, and further includes a limiting assembly disposed on the work plate for limiting the flat wire. The limiting assembly includes a bending connecting plate fixed to the work plate and a bending limiting head corresponding to the rotating assembly. The rotating axes of the bending limiting head and the positioning pin are coaxially arranged, and the bending limiting head has a first limiting groove for the flat wire to pass through and be limited.

[0008] By adopting the above technical solutions, when using the above bending mechanism, the flat wire horizontally passes through the first limiting groove, and the bending limiting head plays a limiting effect on the flat wire. Then, the rotating assembly is started to drive the positioning pin to rotate. When the positioning pin abuts against the flat wire, the flat wire will be bent along the axis of the opening of the first limiting groove. Through the setting of the above limiting assembly, compared with the clamping assembly of the prior art, the limiting assembly of the present application has a simple structure, convenient operation, and the coaxial arrangement of the rotating axes of the bending limiting head and the positioning pin makes the stability of the flat wire bending relatively ideal.

[0009] Optionally, the bending limit head includes a bending connection seat fixed to the bending connection plate, a bending head fixed to the bending connection seat, and a bending cover plate connecting the bending head. There is the first limit groove between the bending head and the bending cover plate.

[0010] By adopting the above technical solution, the structure of the bending limit head is disclosed. The bending connection seat is fixed to the bending connection plate to fix the whole bending limit head. The first limit groove formed between the bending head and the bending cover plate plays a role in limiting the flat wire. The bending limit head has the advantages of simple structure and convenient assembly.

[0011] Optionally, the bending connection seat includes a connection disk and a connection part. The connection disk is fixedly connected to the bending connection plate. The bending connection plate has an installation through hole for arranging the connection part. The connection part is provided with a positioning groove on the side far from the connection plate. The bending head has a positioning convex rib matching with the positioning groove.

[0012] By adopting the above technical solution, the bending connection seat is fixed through the connection disk and the bending connection plate. The connection part is located in the installation through hole, which can improve the connection strength between the bending connection seat and the bending connection plate. With the cooperation of the positioning groove and the positioning convex rib, it is convenient to fix the connection disk and the bending head, and at the same time, limit the extending direction of the first limit groove.

[0013] Optionally, a guiding seat is arranged on one side of the working plate where the bending connection plate is located. The guiding seat has a second limit groove corresponding to and communicating with the first limit groove.

[0014] By adopting the above technical solution, the arrangement of the guiding seat and the second limit groove on the guiding seat can increase the part of the flat wire that is overall limited, and further improve the stability of the flat wire during bending.

[0015] Optionally, the guiding seat is provided with a guiding surface at the notch of the second limit groove.

[0016] By adopting the above technical solution, the arrangement of the guiding surface facilitates the operator to insert the flat wire into the guiding seat and improves the bending efficiency.

[0017] Optionally, the rotating assembly includes a driving part, a bending flange coaxially connected to the output shaft of the driving part, and a bending motor plate for connecting the driving part and the workbench. The positioning pins are arranged at intervals along the circumference of the bending flange.

[0018] By adopting the above technical solution, the structural composition of the rotating assembly is disclosed. After the driving part is started, it drives the bending flange to rotate. The positioning pins rotate along the axis of the bending flange. After the positioning pins abut against the flat wire, they continue to rotate, thereby realizing the bending of the flat wire. The bending direction is controlled by the forward and reverse rotation of the driving part, and the bending angle is controlled by the rotation angle of the bending flange.

[0019] Optionally, flange mounting holes for mounting the positioning pins are circumferentially spaced on the end face of the bent flange, and a pin sleeve for abutting against the flat wire is sleeved on the positioning pin.

[0020] By adopting the above technical solution, the installation method of the positioning pin and the bent flange is disclosed. The setting of the pin sleeve can improve the connection between the positioning pin and the bent flange, reduce the friction and wear between the flat wire and the positioning pin, and improve the bending stability.

[0021] Optionally, a bending adjustment plate is arranged on the side wall of the workbench. The bending adjustment plate is provided with adjustment holes arranged along the axial direction, and adjustment screws fixed to the driving part motor plate are arranged in the adjustment holes of the bending motor plate.

[0022] By adopting the above technical solution, the fixed connection between the bending motor plate and the workbench is realized through the bending adjustment plate. The sliding of the adjustment part in the adjustment hole can adjust the distance between the bending motor plate and the work plate.

[0023] Optionally, the width of the mounting plate is less than or equal to the outer diameter of the bent flange.

[0024] By adopting the above technical solution, the width of the mounting plate is smaller than that of the bent flange, so that when the length of the flat wire is longer, the flat wire will not interfere with the mounting seat after being bent at 180°.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Through the setting of the limiting component, the present application has the effects of simple structure and convenient operation, reduces the operation of the clamping component, and the coaxial arrangement of the rotation axes of the bending limiting head and the positioning pin makes the stability of the flat wire during bending relatively ideal;

[0027] 2. Through the setting of the guide seat, the present application can increase the limiting parts when the flat wire is bent, and further improve the stability of the flat wire during bending;

[0033] The following further describes the present application in detail with reference to the Figures 1-3 accompanying drawings.

[0038] The bending limiting head 32 includes a bending connecting seat 321, a bending head 322 and a bending cover plate 323. The bending connecting seat 321 is integrally a concentric cylinder, and the bending head 322 and the bending cover plate 323 are cylinders. The bending connecting seat 321, the bending head 322 and the bending cover plate 323 are all coaxially arranged.

[0039] The bent connection seat 321 includes a connection disk 3211 located at the top of the bent connection plate 31 and a connection portion 3212 located at the bottom of the connection disk 3211. The connection disk 3211 and the connection portion 3212 are integrally formed. The connection disk 3211 and the bent connection plate 31 are fixed by bolts, that is, the bent limit head 32 is integrally fixed to the bent connection plate 31 through the connection disk 3211.

[0040] The bent connection plate 31 is provided with an installation through hole 311 that penetrates both end faces and through which the connection portion 3212 passes. The inner diameter of the installation through hole 311 is adapted to the outer diameter of the connection portion 3212. The connection portion 3212 has a positioning groove 3213 that penetrates the opposite side walls in the horizontal direction on the side away from the connection disk 3211.

The bent head 322 also has through holes for bolt fixation on both sides of the positioning rib 3221. Through the cooperation of the positioning rib 3221 and the positioning groove 3213, the positioning of the through holes is achieved, facilitating the bolt fixation of the bent head 322 and the connection portion 3212.

[0041] The bottom of the bent head 322 has a first limiting groove 3222 for the flat wire to pass through. The radial width of the first limiting groove 3222 is adapted to the width of the flat wire.

[0043] Combined Figure 2 and Figure 3 , the rotating assembly 2 includes a driving member 21, a bent flange 22, and a bent motor plate 23. The driving member 21 includes a servo motor 211 and a planetary reducer 212. The structure of the driving member 21 is the same as that of the prior art, so it will not be described in this application.

[0044] The bent motor plate 23 is fixed to the end face of the planetary reducer 212. The bent flange 22 is coaxially fixed to the output shaft of the planetary reducer 212, and the bent flange 22 vertically passes through the working through hole 11 and is partially located at the top of the work plate 1. The bent limit head 32 and the bent flange 22 are also coaxially arranged. Among them, the width of the guide seat 4 is smaller than the diameter of the bent flange 22, that is, the length of the guide seat 4 in the X direction is smaller than the diameter of the bent flange 22, which is used to reduce the probability of interference between the flat wire folded into a U shape and the guide seat 4.

[0045] A plurality of flange mounting holes 221 are evenly arranged at intervals in the circumferential direction of the outer edge of the end face of the bent flange 22. At least one positioning pin 24 for bending is fixed in the flange mounting hole 221 of the bent flange 22. In this embodiment, two positioning pins 24 are installed on the bent flange 22, and a limiting gap for the flat wire to pass through is provided between the two positioning pins 24. Among them, a pin sleeve 241 is also sleeved on the positioning pin 24 to reduce the friction and wear between the flat wire and the positioning pin 24.

[0046] A bending adjustment plate 12 for connecting the bending motor plate 23 is provided on the side wall of the workbench. The bending adjustment plate 12 has through holes penetrating both side walls, and bolts fixedly connected to the workbench are arranged in the through holes. An adjustment hole 121 is provided on the side of the bending adjustment plate 12 facing the driving member 21. The adjustment hole 121 is a U-shaped hole, which extends along the Z direction. An adjustment member 122 for connecting the bending motor plate 23 is arranged at the adjustment hole 121 of the bending adjustment plate 12. By adjusting the position of the adjustment member 122 in the adjustment hole 121, the distance between the bending motor plate 23 and the bottom of the workbench can be adjusted. In this embodiment, the adjustment member 122 is an adjustment bolt.

[0047] The implementation principle of a flat wire bending mechanism according to an embodiment of the present application is as follows: when using the above bending mechanism, the flat wire horizontally passes through the second limiting groove 41 and the first limiting groove 3222 in sequence, and passes through the limiting gap; after the flat wire extends to the required bending length, the rotating assembly 2 is started, the positioning pin 24 abuts against the flat wire and continues to rotate, and the flat wire is bent with the opening of the first limiting groove 3222 as the axis. After one section of bending is completed, the flat wire is continuously conveyed, and the bending operation is repeated to bend the flat wire into a U shape.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
