Abstract

This utility model relates to the field of bending processing technology, and specifically to a manual wire bending mechanism. This utility model uses a positioning fixture to position the workpiece. A driving component drives the upper bending blade on the bending frame to move relative to the fixed bending blade, causing the pressure block to press the workpiece firmly onto the positioning fixture. The driving component then drives the upper bending blade to bend the workpiece on the positioning fixture once more. A power component then drives the lower bending blade to cooperate with the fixed bending blade and the upper bending blade to form a secondary bend, thereby bending the wire workpiece into a predetermined shape. In small-batch, multi-variety production modes, this allows for rapid fulfillment of wire processing requirements, ensures assembly process requirements, reduces production costs, and enables non-destructive bending of the wire during the secondary bend.

Description

Technical Field

[0001] This utility model relates to the field of bending processing technology, and specifically to a manual wire bending mechanism. Background Technology

[0002] With the continuous development of science and technology, especially the continuous upgrading of 3C consumer products, the products are becoming smaller and more compact.

However, when pre-processing ribbon cables, in small-batch, multi-variety production modes, without bending parameters, existing ribbon cable bending equipment is prone to causing excessive or insufficient bending of the ribbon cable products. The debugging also consumes a lot of time. If manual methods are used, it is difficult to bend the product to the target shape and size. At the same time, the efficiency of manual operation is extremely low and cannot meet production needs. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1-3 As shown, a manual folding wire mechanism includes:

[0028] A base plate 1 is provided with a processing station, and a positioning fixture 7 for positioning a workpiece 73 is provided on the processing station. A fixed bending knife 9 is provided on one side of the positioning fixture 7.

[0029] An upper bending assembly is disposed above the positioning fixture 7. The upper bending assembly includes a bending frame 2, which is drivenly connected to a driving component 5. An upper bending blade 3 is disposed on the bending frame 2, and the upper bending blade 3 is disposed opposite to a fixed bending blade 9. The driving component 5 is used to drive the upper bending blade 3 on the bending frame 2 to move relative to the fixed bending blade 9 in order to bend the workpiece 73 on the positioning fixture 7.

[0030] A bottom bending assembly is disposed below the positioning fixture 7. The bottom bending assembly includes a lifting frame, on which a lower bending blade 8 is disposed. The lower bending blade 8 is disposed opposite to the fixed bending blade 9 and the upper bending blade 3. The lifting frame is driven and connected to a power component 6. The power component 6 is used to drive the lower bending blade 8 to cooperate with the fixed bending blade 9 and the upper bending blade 3 to form a secondary bend.

[0031] The pressing assembly 4 is disposed on the bending frame 2. The pressing assembly 4 includes a pressing block 41. The pressing block 41 is connected to the bending frame 2 through a guide component. The pressing block 41 is disposed opposite to the upper bending knife 3. The pressing block 41 is used to press the workpiece 73 onto the positioning fixture 7, and then the upper bending knife 3 bends the workpiece 73.

[0032] This invention uses a positioning fixture 7 to position the workpiece 73. The driving component 5 drives the upper bending knife 3 on the bending frame 2 to move relative to the fixed bending knife 9, so that the pressure block 41 presses the workpiece 73 onto the positioning fixture 7. Then, the driving component 5 continues to drive the upper bending knife 3 to bend the workpiece 73 on the positioning fixture 7 once. The power component 6 then drives the lower bending knife 8 to cooperate with the fixed bending knife 9 and the upper bending knife 3 to form a second bend, thereby bending the wiring workpiece 73 into a predetermined shape. In a small-batch, multi-variety production mode, the processing requirements of wiring can be quickly met, the assembly process requirements can be guaranteed, and the production cost can be reduced. The second bend can achieve non-destructive bending of the wiring.

[0033] In one embodiment of the present invention, the positioning fixture 7 includes a fixture frame, a fixture plate 71 is provided on the fixture frame, a fixture groove matching the workpiece 73 is provided on the fixture plate 71, and a positioning pin 72 is provided on the fixture plate 71, the positioning pin 72 passing through the hole of the workpiece 73.

[0034] Specifically, the workpiece 73 is placed on the positioning fixture 7, and the workpiece 73 is positioned by the fixture groove and positioning pin 72 on the fixture plate 71. The positioning is achieved by using the hole position and contour structure of the product to ensure the processing accuracy of subsequent bending.

[0035] In one embodiment of this utility model, the guiding component includes a guide rod 42, the bending frame 2 is provided with a guide hole 43, the guide rod 42 passes through the guide hole 43, the free end of the guide rod 42 is connected to the pressure block 41, and a guide spring 44 is sleeved on the guide rod 42. One end of the guide spring 44 abuts against the bending frame 2, and the other end abuts against the pressure block 41.

[0036] Specifically, the push-pull quick clamp 55 drives the drive block 53 to move along the guide rail 52 toward the workpiece 73, causing the upper bending blade 3 and the pressure block 41 on the bending frame 2 to move toward the workpiece 73. The pressure block 41 is closer to the workpiece 73 than the upper bending blade 3, so that the pressure block 41 first abuts against the workpiece 73 to achieve pressure positioning of the workpiece 73. The pressure block 41 first presses down on the product to prevent it from warping during the bending process. The guide spring 44 can be adjusted by replacing it with springs of different elastic coefficients. During the movement, the upper bending presses down on the ribbon cable workpiece 73 to perform bending deformation.

[0037] In one embodiment of this utility model, the guide rod 42 has a polygonal cross-section, and the guide hole 43 matches the cross-sectional shape of the guide rod 42; the pressure block 41 is provided with a mounting hole, the guide rod 42 is inserted into the mounting hole, a screw is provided on one side of the pressure block 41, the screw passes through the connecting screw hole 45, the connecting screw hole 45 is connected to the mounting hole, and the guide rod 42 is fixedly connected to the pressure block 41 by the screw.

[0038] Specifically, the guide rod 42 has a polygonal cross-section, and the guide hole 43 matches the guide rod 42 to form a guiding function, avoiding problems such as rotation of the pressure block 41, ensuring the stability of the pressure, and preventing warping during bending.

[0039] In one embodiment of the present invention, the driving component 5 includes a driving frame 51 and an upper push-pull quick clamp 55 disposed on the driving frame 51. A guide rail 52 is disposed on the driving frame 51, and a driving block 53 is slidably disposed on the guide rail 52. The bending frame 2 is disposed on the driving block 53. The upper push-pull quick clamp 55 is drivenly connected to the driving block 53, and the upper push-pull quick clamp 55 drives the driving block 53 to reciprocate along the guide rail 52.

[0040] Specifically, pushing the upper push-pull quick clamp 55 drives the drive block 53 downward, compressing the guide spring 44, thereby driving the upper bending blade 3 on the bending frame 2 to move towards the workpiece 73, so that it moves relative to the fixed bending blade 9 to bend the workpiece 73 on the positioning fixture 7 once, quickly realizing the processing requirements of wiring, ensuring the assembly process requirements, and reducing production costs.

[0041] In one embodiment of the present invention, a limiting frame 56 is provided on the drive frame 51, the limiting frame 56 is provided with a threaded hole, and a limiting bolt 57 is provided on the threaded hole. The limiting bolt 57 is disposed opposite to the drive block 53.

[0042] Specifically, the limiting bolt 57 is positioned opposite to the driving block 53. The relative position of the limiting bolt 57 and the driving block 53 can be adjusted by rotating the limiting bolt 57 to limit the stroke of the driving block 53 and prevent its stroke from being too large or too small, thus affecting the bending quality.

[0043] In one embodiment of this utility model, the power component 6 includes a power frame 68, a slide rail is provided on the power frame 68, a slider 69 is slidably mounted on the slide rail, a lifting frame is mounted on the slider 69, the slider 69 is driven and connected to a driver, a fixing plate 691 is provided on the power frame 68, a lifting spring 692 is provided between the fixing plate 691 and the slider 69, and the driver drives the slider 69 to reciprocate along the slide rail.

[0044] Specifically, the driver drives the slider 69 to move along the slide rail, thereby driving the lower bending knife 8 on the lifting frame to perform a secondary bending of the workpiece 73. The forming effect is good, and in the production mode of small batch and multiple varieties, the processing requirements of the wiring can be quickly realized. A lifting spring 692 is provided between the fixed plate 691 and the slider 69, which can buffer the movement of the lower bending knife 8, avoid excessive impact and damage to the workpiece 73, and ensure the bending quality.

[0045] In one embodiment of this utility model, the driver includes a guide plate 62 and a push-pull quick clamp 61. The guide plate 62 is provided with a guide hole, and a power plate 63 passes through the guide hole. The push-pull quick clamp 61 is drivenly connected to the power plate 63. The bottom of the slider 69 is provided with a roller 67 opposite to the power plate 63. The power plate 63 is provided with a first surface 64 and a second surface 65. The first surface 64 and the second surface 65 form a stepped structure with different heights through an inclined surface 66. The push-pull quick clamp 61 drives the power plate 63 to reciprocate, causing the roller 67 on the slider 69 to move along the first surface 64, the inclined surface 66, and the second surface 65 to drive the slider 69 to move up and down.

[0046] Specifically, the push-pull quick clamp 61 drives the power plate 63 to move, causing the roller 67 on the slider 69 to move along the first surface 64, the inclined surface 66, and the second surface 65. Since the first surface 64 and the second surface 65 form a stepped structure through the inclined surface 66, the roller 67 moves from the lower surface to the higher surface, thereby pushing the slider 69 to move upward along the slide rail. This causes the lower bending blade 8 on the lifting frame to cooperate with the fixed bending blade 9 and the upper bending blade 3 to form a secondary bend. The inclined surface 66 and the roller 67 cooperate to form a lifting mechanism, which, together with the slide rail, converts the horizontal movement into vertical movement, reducing the space required for the driver and facilitating manual bending. The inclined surface 66 with its stepped structure allows for slow bending of the ribbon cable product, resulting in a better bending effect.

[0047] In one embodiment of the present invention, the positioning fixture 7 is provided with an installation groove 91, the fixed bending knife 9 is disposed on the installation groove 91, the fixed seat 92 of the fixed bending knife 9 is provided with a guide groove 93 that matches the lower bending knife 8, and the lower bending knife 8 is slidably disposed on the guide groove 93.

[0048] Specifically, the fixed bending blade 9 is set on the mounting groove 91, which can ensure the positional accuracy of the fixed bending blade 9 and ensure the consistency of bending. The lower bending blade 8 is slidably set on the guide groove 93, which can ensure the matching accuracy between the lower bending blade 8 and the fixed bending blade 9, avoid problems such as relative position offset, and improve bending accuracy.

[0049] In one embodiment of this utility model, the fixed bending blade 9 is provided with a supporting surface 32 and a forming surface 33, the lower bending blade 8 is provided with a lifting surface 34, a bending space is formed between the forming surface 33 and the lifting surface 34, the upper bending blade 3 is provided with a bending protrusion 31 that matches the bending space, and a pressing surface and a fixing surface are respectively provided on both sides of the bending protrusion 31. The pressing surface is arranged opposite to the supporting surface 32, and the fixing surface is arranged opposite to the lifting surface 34.

[0050] Specifically, the support surface 32 and forming surface 33 on the fixed bending blade 9 and the upper bending blade 3 bend the workpiece 73 once, which can form a part with a bending tendency on the workpiece 73. The lower bending blade 8 bends the workpiece 73 a second time with the fixed surface and the bending protrusion 31 degrees. It can bend the workpiece 73 according to the required shape during the pre-processing of the wiring harness, so as to achieve non-destructive bending of the wiring harness.

[0051] Usage process

[0052] Workpiece 73 is placed on positioning fixture 7. The fixture slot and positioning pin 72 on fixture plate 71 limit the position of workpiece 73. Positioning is achieved using the hole positions and contour structure of the product to ensure the processing accuracy of subsequent bending. The upper push-pull quick clamp 55 is pushed to drive the drive block 53 to move along the guide rail 52 toward workpiece 73, so that the upper bending knife 3 and the pressure block 41 on the bending frame 2 move toward workpiece 73. The pressure block 41 is closer to workpiece 73 than the upper bending knife 3, so that the pressure block 41 first abuts against workpiece 73 to achieve pressure positioning of workpiece 73. The upper push-pull quick clamp 55 is pushed to drive the drive block 53 downward, compressing the guide spring 44, thereby driving the bending frame 2. The upper bending blade 3 moves toward the workpiece 73, causing it to move relative to the fixed bending blade 9 to bend the workpiece 73 on the positioning fixture 7. The lower push-pull quick clamp 61 drives the power plate 63 to move, causing the roller 67 on the slider 69 to move along the first surface 64, the inclined surface 66, and the second surface 65. Since the first surface 64 and the second surface 65 form a high-low stepped structure through the inclined surface 66, the roller 67 moves from the lower surface to the higher surface, thereby pushing the slider 69 to move upward along the slide rail. This causes the lower bending blade 8 on the lifting frame to cooperate with the fixed bending blade 9 and the upper bending blade 3 to form a secondary bend, thereby bending the wiring workpiece 73 into a predetermined shape, quickly achieving the processing requirements of wiring, ensuring assembly process requirements, and reducing production costs.
