Abstract
Description
Technical Field
[0001] This utility model relates to the field of manual flat wire folding technology, and in particular to a simple manual flat wire folding fixture. Background Technology
[0002] Existing technologies for flat wire bending fixtures mainly employ a semi-mechanized forming method and use two-stage stamping. First, the flat wire is bent into a U-shape using the first bending fixture, and then the flat wire is bent into the desired hair clip shape using the second bending fixture.
[0003] The tooling involved in the entire zigzag process is very complicated. In addition, since the two stamping processes are in different directions, stamping equipment in at least two directions is required, and the mechanical equipment structure involved is quite complicated. Utility Model Content
[0004] To overcome the shortcomings of the problems mentioned in the background, this utility model provides a simple manual flat wire bending tool.
[0005] The technical solution is as follows: A simple manual flat wire bending fixture, comprising a first bending fixture and a second bending fixture; characterized in that the second bending fixture includes a base plate, a limiting plate, a left stop bar, a right stop bar, a pressure block, and guide posts; the base plate is fitted with the limiting plate; the limiting plate is bolted to the left stop bar; the base plate is connected to two guide posts; the two guide posts are slidably connected to the pressure block; the pressure block is bolted to the right stop bar; there is a gap between the left stop bar and the limiting plate, and a gap between the right stop bar and the pressure block, the two gaps being used to clamp the ends of two flat wires respectively.
[0006] As an improvement to the above solution, a damper is installed inside the guide post.
[0007] As an improvement to the above scheme, when the pressure block is located at the top of the guide post, the left and right stop bars are on the same horizontal line.
[0008] As an improvement to the above solution, the first zigzag tooling includes a first limiting block, a second limiting block, and a rotating shaft; the first limiting block is connected to the rotating shaft; the first limiting block is rotatably connected to the second limiting block via the rotating shaft; both the first and second limiting blocks are provided with a groove, and both grooves are used to place flat wire.
[0009] As an improvement to the above scheme, the two grooves are located in the middle of the first limiting block and the second limiting block, respectively.
[0010] As an improvement to the above scheme, the first folding tooling also includes a mounting plate and a pressure plate; the mounting plate is rotatably connected to two symmetrically distributed pressure plates; the mounting plate is provided with a protrusion, and there is a gap between the side of the protrusion and the extrusion part, which is used to cooperate with the two pressure plates to restrict the flat line.
[0011] As an improvement to the above solution, the protrusion is set in a "V" shape on one side away from the two pressure plates.
[0012] As an improvement to the above solution, anti-slip pads are provided on the surfaces of the pressure block, the first limiting block, the second limiting block, and the pressure plate.
[0013] Beneficial effects: This utility model involves manually pressing down the pressure block and the right stop bar. The end of the flat wire located in the gap between the pressure block and the right stop bar will be bent first. Then, with further pressing down, since the end of the flat wire in the gap between the limiting plate and the left stop bar remains stationary, the end of the flat wire in the gap between the pressure block and the right stop bar will drive the middle of the flat wire to bend, thereby obtaining the finished product and completing the flat wire bending work. The two-stage stamping forming in two directions in the prior art is completed in one press down. At the same time, one-stage forming can better control the shape of the flat wire.
[0014] This invention is entirely manual. During the folding process, the flat wire is restricted in its movement by the clamp, so it will not rub against the surface of the tooling. As a result, the paint on the surface of the flat wire remains intact after folding, improving product quality. Compared with existing tooling, the size and shape of the parts required by this manual folding tooling are simpler, and the number of parts is also smaller. It is easy to operate and learn. Furthermore, since this folding tooling does not involve mechanical equipment, the folding process is simple and easy to understand, making it convenient to learn. Attached Figure Description

[0021] Example 1
[0022] A simple manual folding tool for flat wire, such as... Figures 1-4 As shown, the fixture includes a first folding tool and a second folding tool; characterized in that the second folding tool includes a base plate 101, a limiting plate 102, a left stop bar 103, a right stop bar 104, a pressure block 105, and guide posts 106; the limiting plate 102 is installed on the base plate 101; the left stop bar 103 is bolted to the limiting plate 102, and there is a gap between the limiting plate 102 and the left stop bar 103, the size of which can be adjusted by turning the bolts; two guide posts 106 are connected to the base plate 101; the pressure block 105 is slidably connected to the two guide posts 106; the right stop bar 104 is bolted to the pressure block 105, and there is a gap between the pressure block 105 and the right stop bar 104, the size of which can be adjusted by turning the bolts; the two gaps are respectively used to clamp the ends 1001 of two flat wires.
[0023] A damper 10601 is installed inside the guide post 106 to limit the pressing distance when the pressure block 105 is pressed down manually, so as to avoid excessive pressing distance and excessive bending of the flat wire 1.
[0024] When the pressure block 105 is located at the top of the guide post 106, the left stop bar 103 and the right stop bar 104 are on the same horizontal line, so that when the flat wire 1 is installed, the flat wire 1 is placed in a horizontal position.
[0025] The first zigzag tooling includes a first limiting block 201, a second limiting block 202, and a rotating shaft 203; the first limiting block 201 is connected to the rotating shaft 203; the first limiting block 201 is rotatably connected to the second limiting block 202 through the rotating shaft 203; a groove 20101 is provided on both the first limiting block 201 and the second limiting block 202.
[0026] The two grooves 20101 are located in the middle of the first limiting block 201 and the second limiting block 202, respectively, so that the two grooves 20101 can be positioned manually at the same time and the flat wire 1 can be placed in the two grooves 20101.
[0027] The first folding tooling also includes a mounting plate 211 and a pressure plate 212; two symmetrically distributed pressure plates 212 are rotatably connected to the mounting plate 211; a protrusion 21101 is provided on the mounting plate 211, and there is a gap between the side of the protrusion 21101 and the extrusion part 21201.
[0028] The protrusion 21101 is arranged in a "V" shape on one side away from the two pressure plates 212.
[0029] The surfaces of the pressure block 105, the first limiting block 201, the second limiting block 202, and the pressure plate 212 are all provided with anti-slip pads to prevent slipping during manual operation and to prevent safety hazards.
[0030] The specific workings of this utility model are as follows:
[0031] refer to Figure 1 As shown, firstly, using the first folding fixture, the flat wire 1 is manually placed into the two grooves 20101. Then, by manually rotating the second limiting block 202, the grooves 20101 on the second limiting block 202 fold the flat wire 1 into a "V" shape. Then, referring to... Figure 2 As shown, the "V"-shaped flat wire 1 is inserted into the gap between the side of the pressing part 21201 and the protrusion 21101 of the two pressure plates 212, and the pressing part 21201 is rotated to continuously press the flat wire 1 to deform it, while the protrusion 21101 is used to fold the flat wire 1 into a "U" shape.
[0032] Furthermore, through the second zigzag tooling, referencing Figure 3 As shown, insert the two flat wire ends 1001 into the gaps between the limiting plate 102 and the left stop bar 103, and the gap between the pressure block 105 and the right stop bar 104, respectively, and lock the flat wire ends 1001 with screws. Then, manually press down the pressure block 105 and the right stop bar 104. It should be noted that during this pressing process, the flat wire ends in the gaps between the pressure block 105 and the right stop bar 104 will be bent first. Then, with further pressing down by the pressure block 105 and the right stop bar 104, since the flat wire ends 1001 in the gaps between the limiting plate 102 and the left stop bar 103 remain stationary, the flat wire ends 1001 in the gaps between the pressure block 105 and the right stop bar 104 will drive the middle of the flat wire to bend until the pressure block 105 and the right stop bar 104 are pressed down to the required size and then stop. Then, manually turn the screws to remove the flat wire 1, thus obtaining the finished product and completing the flat wire 1 bending work. (Refer to...) Figure 4 As shown, it should be noted that the second folding tooling completes two stamping processes in two directions in the prior art through a single downward press. In this way, the shape of the flat line 1 can be better controlled in one forming.
[0033] Furthermore, the entire bending process is manually operated and simple, requiring no mechanical equipment. Simultaneously, the flat wire 1 is restricted in its movement during bending, preventing friction with the tooling surface. This ensures the paint on the flat wire 1 remains intact after bending, improving product quality. Moreover, for some prototype flat wire motors where efficiency is not a primary concern initially, using this manual bending fixture can significantly reduce the cost of tooling and related machinery, lowering initial investment. The simple fixture structure and machining processes also significantly shorten the initial processing cycle. Furthermore, since no mechanical equipment is involved in the entire manual bending process, it is safer.
[0034] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
