Description

Technical Field

[0001] This utility model relates to the field of bending machines, and in particular to a coil bending machine. Background Technology

[0002] A wire coil bending machine is a device used to process wires, capable of bending wires into various shapes to meet different needs.

[0003] In practical applications, coil bending machines not only improve production efficiency but also enhance product quality. Compared to traditional manual bending, automatic bending machines significantly reduce labor intensity and avoid product quality inconsistencies caused by human fatigue.

[0004] However, coils processed on traditional coil bending machines simply fall directly into a collection box for collection. They then need to be placed on a vibrating screen for sorting and guidance before further processing, which increases production costs and reduces production efficiency. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a coil bending machine that solves the problem that in traditional electric coil bending machines, the coils processed on the machine simply fall into a collection box for collection and then need to be placed on a vibrating screen for sorting and guidance before further processing, which leads to increased production costs and reduced production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coil bending machine, comprising a conveying assembly for stripping and tinning wire harnesses and a bending assembly for forming coils at the wire outlet end of the conveying assembly, the bending assembly being provided with a discharge assembly; the bending assembly includes a rotating component corresponding to the wire harness and a cutting component located beside the rotating component; the discharge assembly includes a guide component located on the other side of the rotating component and a discharge channel corresponding to the end of the rotating component; when the cutting component cuts the coil formed on the rotating component, the guide component pulls the coil into the discharge channel, thereby changing the direction and position of the coil discharged at the outlet end of the discharge channel.

[0007] Furthermore, the guide includes a sleeve disposed on the first drive member and connected to the output shaft of the first drive member. The sleeve has a first port corresponding to the coil, and the sleeve and the cutting member are disposed opposite to each other.

[0008] Furthermore, the cutting component includes a second driving component and a cutting blade connected to the output end of the second driving component, with the blade edge of the cutting blade corresponding to the connection point of the coil and the wire harness.

[0009] Furthermore, the sleeve has a cross-section on one side corresponding to the cutting blade, and the cross-section extends into the first through-hole, so that the sleeve can be pushed by the first driving member, allowing the coil on the rotating member to enter the first through-hole through the cross-section.

[0010] Furthermore, the cutting blade is equipped with a pusher, the pusher end of which covers the two legs of the coil.

[0011] Furthermore, the cutting blade and the pushing component are staggered, with the cutting blade's edge corresponding to the connection between the coil and the wire harness, and the pushing component corresponding to the end wall after the coil has been cut.

[0012] Furthermore, the discharge channel includes a receiving block and a track bar that are sequentially connected to the sleeve, and the receiving block and the track bar are provided with a second port that is connected to the first port.

[0013] Furthermore, one side of the sleeve, receiving block, and track bar is provided with an extension port that communicates with the first port and the second port, and one leg of the coil passes through the extension port.

[0014] Furthermore, the track is an arc-shaped bar, so that when the coil sliding inside the track is discharged, it changes from longitudinal to transverse.

[0015] Furthermore, the track has a 90° gradual curve, which causes the coil sliding within the track to change the orientation of its support legs as the track changes.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, after the rotating part twists the wire harness to form a coil, the guide part moves and sleeves the coil on the rotating part, so that the cutting part pushes the connection between the cutting coil and the wire harness, causing the coil to fall into the guide part and slide into the discharge channel. This is used to transport the coil and change the position of the coil pins, so that the coil made by the bending machine can be further processed without the need for subsequent use of a vibrating screen for differentiation and guidance.

[0017] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0031] Please refer to Figure 1-8 The diagram illustrates the specific structure of a preferred first embodiment of the present invention, a coil bending machine. It includes a conveying assembly 10 for stripping and tinning a wire harness 1, and a bending assembly 20 located at the wire outlet end of the conveying assembly 10 for forming a coil 2. The bending assembly 20 has a discharge assembly 30. The bending assembly 20 includes a rotating component 21 corresponding to the wire harness 1 and a cutting component 22 located beside the rotating component 21. The discharge assembly 30 includes a guide component 31 located on the other side of the rotating component 21 and a discharge channel 32 corresponding to the end of the rotating component 21. When the cutting component 22 cuts the coil 2 formed on the rotating component 21, the guide component 31 pulls the coil 2 into the discharge channel 32, thereby changing the direction and position of the coil 2 discharged from the outlet end of the discharge channel 32. This is different from existing coil bending machines where coils are directly dropped into a collection box after production. In this coil bending machine, after the rotating part 21 twists the wire harness 1 into coil 2, the guide part 31 moves and engages with the coil 2 on the rotating part 21, causing the cutting part 22 to push and cut the connection between the coil 2 and the wire harness 1, so that the coil 2 falls into the guide part 31 and slides into the discharge channel 32. This conveys the coil 2 and changes the position of the coil 2 pins, so that the coil 2 produced by the bending machine can be further processed without the need for subsequent separation and guidance by a vibrating screen.

[0032] like Figure 3As shown, exemplarily, the guide 31 includes a sleeve 312 connected to the output shaft of the first drive member 311 and a first through-hole 313 corresponding to the coil 2 on the sleeve 312, and the sleeve 312 is disposed opposite to the cutting member 22. When the rotating member 21 twists the wire harness 1 to form the coil 2, it translates along the output axis of the first drive member 311 in the direction of the coil 2, so that the sleeve 312 fits the coil 2 on the rotating member 21. After the cutting member 22 cuts the connection between the coil 2 and the wire harness 1, the fallen coil 2 slides directly from the inner cavity of the sleeve 312 into the discharge channel 32.

[0033] like Figure 6-7 As shown, exemplarily, the cutting component 22 includes a second driving component 221 and a cutting blade 222 connected to the output end of the second driving component 221. The blade of the cutting blade 222 corresponds to the connection point between the coil 2 and the wire harness 1. When the rotating component 21 twists the wire harness 1 to form the coil 2, and the sleeve 312 is fitted with the coil 2, the cutting blade 222 moves to the connection point between the coil 2 and the wire harness 1 as the output axis of the second driving component 221 translates in the direction of the coil 2, causing the coil 2 and the wire harness 1 to separate, allowing the coil 2 to fall into the sleeve 312.

[0034] like Figure 3 As shown, for example, the sleeve 312 has a cut-off surface 314 on one side corresponding to the cutting blade 222. The cut-off surface 314 extends into the first opening 313, so that the sleeve 312 can be pushed by the first driving member 311, allowing the coil 2 on the rotating member 21 to enter the first opening 313 through the cut-off surface 314. When the rotating component 21 twists the wire harness 1 to form the coil 2, and the sleeve 312 is fitted onto the coil 2, in order to prevent the pins of the coil 2 from bending after the cutting blade 222 cuts the connection between the coil 2 and the wire harness 1, a cut surface 314 is opened on the side of the sleeve 312 corresponding to the cutting blade 222. By opening the cut surface 314, the first opening 313 on the sleeve 312 is exposed, and the end wall of the cut surface 314 is also exposed. At this time, the blade of the cutting blade 222 can correspond to the end wall of the cut surface 314, so that when the cutting blade 222 cuts the connection between the coil 2 and the wire harness 1, the pins of the coil 2 correspond to the end wall of the cut surface 314, thereby preventing the pins of the coil 2 from bending due to the squeezing and cutting by the cutting blade 222.

[0035] To further prevent the leads of coil 2 from bending during cutting by the cutting blade 222, the cutting blade 222 is equipped with a pusher 3, the pushing end of which covers the two leads of coil 2. The cutting blade 222 and the pusher 3 are staggered, with the blade edge of the cutting blade 222 corresponding to the connection between coil 2 and wire harness 1, and the pusher 3 corresponding to the end wall of coil 2 after the cut surface 314 is formed. When the cutting blade 222 cuts the connection between coil 2 and wire harness 1, the pusher 3 can squeeze the two leads of coil 2, causing them to contact the end wall of the cut surface 314 under the pressure of the pusher 3, thereby preventing the leads of coil 2 from bending when the cutting blade 222 cuts the connection between coil 2 and wire harness 1.

[0036] like Figure 5 As shown, exemplarily, the discharge channel 32 includes a receiving block 321 and a track bar 322 that are sequentially connected to the sleeve 312. The receiving block 321 and the track bar 322 are provided with a second opening 315 that communicates with the first opening 313. When the cutting blade 222 cuts the connection between the coil 2 and the wire harness 1, causing the coil 2 to fall into the sleeve 312, in order to change the position of the coil 2 pins, the discharge channel 32 is divided into the receiving block 321 and the track bar 322. The feeding end of the receiving block 321 is located at the lower end of the output shaft of the rotating component 21. After the sleeve 312 is fitted onto the coil 2 on the rotating component 21, the first opening 313 on the sleeve 312 corresponds to the second opening 315 on the receiving block 321. The cut coil 2 slides from the first opening 313 on the sleeve 312 into the second opening 315 and then enters the track bar 322 until it is discharged.

[0037] like Figure 8 As shown, for example, one side of the sleeve 312, the receiving block 321, and the track bar 322 is provided with an extension port 4 communicating with the first port 313 and the second port 315, respectively, and one leg of the coil 2 passes through the extension port 4. To prevent the coil 2 from sliding in the first port 313 and the second port 315, and to prevent the coil 2 from getting stuck due to friction, the sleeve 312, the receiving block 321, and the track bar 322 have no operating space except for the two ends, which would affect the operator's ability to push the stuck coil 2 out of the sleeve 312, the receiving block 321, and the track bar 322. An extension port 4 is opened on the side of the corresponding leg of the first port 313 and the second port 315, and one leg of the coil 2 passes through the extension port 4, so as to facilitate the operator to push the coil 2 stuck in any of the sleeve 312, the receiving block 321, and the track bar 322.

[0038] The track 322 is an arc-shaped bar, so that when the coil 2 sliding in the track 322 is discharged, it changes from longitudinal to transverse.

[0039] The track 322 has a 90° gradual bend, which allows the coil 2, which slides within the track 322, to change the orientation of its legs. This allows the legs of the coil 2 to be adapted to subsequent processing equipment.

[0040] It should be noted that the angle of track 322 can also be 10°, 20°, 30°, 40°-360°, etc., to adapt to different processing instruments.

[0041] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
