Abstract
Description
Technical Field
[0001] This utility model relates to the field of flexible flat cable production technology, specifically a tooling for manually bending flexible flat cables. Background Technology
[0002] In fields such as electronic equipment manufacturing, flexible flat cables, as important electrical connection components, often require bending to meet specific installation or layout requirements. Chinese patent CN220554140U discloses a manual bending and positioning fixture for flexible flat cables, which can achieve bending and positioning of the cables, but has significant limitations. This fixture has several positioning slots of different lengths pre-cut on the positioning base; during bending, the flexible flat cable is placed in the corresponding positioning slot. However, because the length of the positioning slots is fixed, different specifications of flexible flat cables (such as different length and bending point requirements) require different types of tooling, meaning the cable specifications and tooling must be matched one-to-one. This not only increases the tooling manufacturing cost for enterprises but also leads to complex tooling management. Frequent tooling changes when producing multiple specifications of flexible flat cables also reduce production efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a flexible sheet manual bending fixture, which solves the problems mentioned in the background.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a soft sheet manual bending fixture, including a fixture base plate, a ruler, and a slider. The edges of the fixture base plate are respectively provided with a first bending edge and a second bending edge with different bending angles. A groove is opened at the top of the fixture base plate, and the slider slides inside the groove. The ruler is fixed on the upper surface of the fixture base plate, and the scale line set on the ruler is used as a reference for the sliding distance of the slider.
[0005] Furthermore, in the non-sliding state, the slider is internally connected to a fastener, which is a hand-tightening screw.
[0006] Furthermore, a reserved groove is provided at the top of the tooling base plate, and a scale is fixed in the reserved groove. The upper surface of the scale is flush with the upper surface of the tooling base plate, and scale lines are provided on both sides of the scale.
[0007] Furthermore, the top of the tooling base plate is symmetrically connected with limiting strips, and the limiting strips are set as placement positions. The flexible flat cable is placed in the placement positions to constrain it when it is bent.
[0008] Furthermore, the end of the slide is provided with a flared opening for placing or removing the slider.
[0009] Furthermore, a T-shaped protrusion is integrally connected to the bottom end of the slider, and the T-shaped protrusion engages and fits inside the slide groove.
[0010] Furthermore, the slider and the T-shaped protrusion have a threaded hole inside, and the fastener is connected inside the threaded hole, with its bottom end abutting against the groove after it is in place.
[0011] Furthermore, the bottom end of the slider is symmetrically provided with clearance grooves, and the limiting strip is located inside the clearance grooves. The two are adapted to each other and slide relative to each other.
[0012] Furthermore, the angle between the first bent edge and the placement position is 90°, and the angle between the second bent edge and the placement position is 45°.
[0013] This utility model provides a tooling for manual bending of flexible sheet metal. Compared with the prior art, it has the following advantages:
[0014] This flexible flat cable manual bending fixture uses a slider that slides within a groove and is precisely positioned with a ruler, securely locked with fasteners, and works in conjunction with multi-angle bending edges and limit constraint structures. It can flexibly adapt to flexible flat cables with different lengths, bending points, and bending angles, eliminating the need to customize fixtures for each specification of flexible flat cable. This significantly reduces the cost of fixture manufacturing and management for enterprises and greatly improves the production efficiency and bending quality stability of flexible flat cables of various specifications.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-6 This utility model provides a technical solution: a manual bending fixture for flexible flat cables, mainly composed of a fixture base plate 1, a ruler 2, a slider 3, fasteners 4, etc. These components cooperate with each other to achieve manual bending of the flexible flat cables. Specifically:
[0024] The base plate 1 of the tooling serves as the load-bearing foundation for the entire tooling. Its edges are respectively provided with a first bending edge 11 and two second bending edges 12 with different bending angles. The second bending edges 12 are located on both sides of the first bending edge 11. The angle between the first bending edge 11 and the placement position 16 is 90°, and the angle between the second bending edge 12 and the placement position 16 is 45°. This design can meet the processing requirements of flexible flat cable with different bending angles.
[0025] A groove 14 is provided at the top of the tooling base plate 1. The groove 14 is used to guide the sliding of the slider 3. A flared part 141 is provided at the end of the groove 14. The flared part 141 makes it convenient to place the slider 3 into the groove 14 or remove it from the groove 14 when assembling or disassembling the tooling.
[0026] The top of the tooling base plate 1 is also provided with a reserved groove 13. The scale 2 is fixed in the reserved groove 13 on the upper surface of the tooling base plate 1, and the upper surface of the scale 2 is flush with the upper surface of the tooling base plate 1. This design not only ensures the flatness of the tooling surface, but also makes it convenient for operators to observe and use the scale 2. Scale lines are provided on both sides of the scale 2 to match the sliders 3 on both sides of the scale 2. In other words, one scale 2 can simultaneously serve as a reference for the sliding distance of two sliders 3.
[0027] The top of the tooling base plate 1 is symmetrically connected with limiting strips 15, and the limiting strips 15 form a placement position 16. The placement position 16 is used to place the flexible flat cable 5. During the bending process, the limiting strips 15 can restrain the flexible flat cable, prevent the flexible flat cable from deflecting when bending, and ensure the accuracy of the bending part.
[0028] The bottom end of the slider 3 is integrally connected to the T-shaped protrusion 31. The shape of the T-shaped protrusion 31 is adapted to the internal structure of the slide groove 14. The T-shaped protrusion 31 is engaged inside the slide groove 14, so that the slider 3 can slide stably along the slide groove 14. The slider 3 and the T-shaped protrusion 31 have a threaded hole 32 in their interiors. The threaded hole 32 is used to connect the fastener 4. The fastener 4 is a hand-tightening screw. When the slider 3 slides into place, the position of the slider 3 is fixed by tightening the hand-tightening screw. After being tightened to the end, the bottom end of the hand-tightening screw will abut against the bottom surface of the slide groove 14. Under the reaction force, the T-shaped protrusion 31 abuts against the top end of the slide groove 14, thereby achieving fixation.
[0029] The bottom end of the slider 3 is symmetrically provided with clearance grooves 33. The shape of the clearance grooves 33 is adapted to the limiting strip 15. During the sliding process of the slider 3, the limiting strip 15 is located inside the clearance grooves 33, and the two slide relative to each other. This design ensures that the slider 3 can slide normally without interfering with the limiting strip 15.
[0030] Additionally, it should be noted that several sets of slide groove 14, limit bar 15, placement position 16, scale 2, slider 3, and fastener 4 are provided. During the manual bending of the flexible flat cable 5, different bending parts on the same flexible flat cable 5 can be bent, which greatly improves efficiency.
[0031] When using this fixture, based on the preset bending length of the flat cable 5 and referring to the scale line of the ruler 2, the distance between the front end of each slider 3 and the first bending edge 11 or the second bending edge 12 is adjusted. For example, if the flat cable 5 needs to be bent 5cm from its end, the front end of the slider 3 needs to slide to the position indicated by the scale line of the ruler 2 (5cm). Then, the fastener 4 is tightened to fix the slider 3. At this point, the distance between the front end of the slider 3 and the first bending edge 11 is 5cm. The flat cable 5 is then placed in the placement position 16, with the end of the flat cable 5 abutting against the front end of the slider 3. The operator then bends the flat cable 5 downwards. Under the action of the first bending edge 11, the flat cable 5 achieves a 90° bend. The same procedure applies to achieving a 45° bend on the flat cable 5. Compared to existing flat cable bending fixtures, this fixture offers flexible distance adjustment, as it is not fixed and can meet the bending requirements of flat cables 5 of different specifications.
[0032] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
