Description

Technical Field

[0001] This utility model relates to the field of bending production technology, and in particular to a multi-size adjustable manual bending forming tool. Background Technology

[0002] In spring production, especially for irregularly shaped springs that require bending, when the spring coiling machine cannot complete the bending operation in one go, manual bending using a bending fixture is required. However, due to the different dimensions of springs and bending parts, a bending fixture is often required for each size of spring, resulting in a waste of resources. Therefore, the applicant has designed a bending forming fixture that can bend springs of different sizes to different dimensions, enabling bending operations on springs of multiple sizes.

The rotating shaft is vertically mounted on the base, and the rotating sleeve is rotatably mounted on the rotating shaft. The rotating sleeve is provided with a rotating handle. The fixture is characterized by: a limiting plate that moves along the axis of the rotating sleeve on the rotating sleeve; a first limiting hole and a second limiting hole that face vertically upwards on the rotating shaft; the axis of the first limiting hole coincides with the axis of the rotating shaft; at least two second limiting holes arranged around the first limiting hole; a first limiting rod disposed in the first limiting hole; a second limiting rod disposed in any one of the second limiting holes; a limiting hole and a fixing hole disposed on the base; a third limiting rod disposed in the limiting hole; and at least two fixing holes arranged around the rotating sleeve.

[0011] 1. This application adjusts the position of the second limiting rod according to the second limiting hole, and adjusts the rotation angle of the rotating sleeve to adjust the bending angle of the spring bending part; the adjustment of different diameters between the first limiting rod and the second limiting rod is to accommodate springs of different sizes placed between them, and to complete the bending of springs of different sizes; and the adjustment of different diameters of the second limiting rod realizes the adjustment of the spring bending radius; a limiting groove is formed between the limiting plate and the rotating sleeve to facilitate the limiting and bending of the coil spring, and the chamfering treatment at the end of the limiting plate facilitates the limiting and bending of the coil spring, realizing the bending operation of springs of different sizes and different bending dimensions.

[0026] Example 1

[0027] like Figures 1-6 As shown, a multi-size adjustable manual bending forming fixture includes a base 1, a rotating shaft 2, and a rotating sleeve 3. The rotating shaft 2 is vertically mounted on the base 1. The rotating sleeve 3 is rotatably mounted on the rotating shaft 2. The rotating sleeve 3 is provided with a rotating handle 4 and a limiting plate 5 that moves along the axis of the rotating sleeve 3. The rotating shaft 2 is provided with a first limiting hole 106 and a second limiting hole 107 that face vertically upward. The axis of the first limiting hole 106 coincides with the axis of the rotating shaft 2. At least two second limiting holes 107 are arranged around the first limiting hole 106. A first limiting rod 8 is provided in the first limiting hole 106. A second limiting rod 9 is provided in any one of the second limiting holes 107. The base 1 is provided with a limiting hole 10 and a fixing hole 11. A third limiting rod 12 is provided in the limiting hole 10. At least two fixing holes 11 are arranged around the rotating sleeve 3.

[0028] There are multiple first limiting rods 8, each with a different diameter of the portion exposed on the rotating shaft 2; there are also multiple second limiting rods 9, each with a different diameter of the portion exposed on the rotating shaft 2. Adjusting the different diameters of the first limiting rods 8 and the second limiting rods 9 allows for the placement of springs of different sizes between them, thus enabling the bending of springs of different sizes. Adjusting the different diameters of the second limiting rods 9 also adjusts the bending radius of the spring. Adjusting the position of the second limiting rods 9 according to the second limiting hole 107 adjusts the rotation angle of the rotating sleeve 3, thus adjusting the bending angle of the bent portion of the spring. There are also multiple third limiting rods 12, each with a different diameter of the portion exposed on the base 1. By setting different diameters of the third limiting rods 12, the distance between them and the rotating handle 4 is adjusted, thus adjusting the bending angle of the bent portion of the spring.

[0029] The limiting plate 5 is movably mounted on the rotating handle 4 via the fixing bolt 14 and the strip hole 13. The distance from the end of the limiting plate 5 to the first limiting rod 8 can be adjusted to facilitate the limiting of springs of different sizes and to facilitate the bending operation of the springs. The end of the limiting plate 5 is chamfered to prevent scratching the coil spring. The end of the limiting plate 5 near the first limiting rod 8 is chamfered, and a notch is provided on the side near the rotating sleeve 3 to form a limiting groove with the rotating sleeve 3. The limiting groove is formed between the limiting plate 5 and the rotating sleeve 3 to facilitate the limiting and bending of the coil spring. The chamfered end of the limiting plate 5 facilitates the limiting and bending of the coil spring, realizing the bending operation of springs of different sizes and different bending dimensions. The semi-circular protruding corner is chamfered to facilitate the bending operation and make the bending part more natural.

[0030] Example 2

[0031] like Figure 1-2 As shown, this embodiment is obtained by adding technical features such as the limiting bolt 10 on the basis of embodiment one. The other technical features are the same as those in embodiment one. The similarities will not be repeated here. The difference between this embodiment and embodiment one is that the limiting plate 5 is provided with a strip hole 13, and the fixing bolt 14 passes through the strip hole 13 to fix the limiting plate 5 to the rotating handle 4.

[0032] In this embodiment, the strip hole 13 facilitates the movement of the limiting plate 5, and the two fixing bolts 14 ensure that the limiting plate 5 will not loosen or shift when it is bent and used.

[0033] During operation, the bolt passes through the fixing hole 11 to fix the base 1 on the operating table. The rotating sleeve 3 is fitted onto the rotating shaft 2. The first limiting rod 8 is inserted into the first limiting hole 106, the second limiting rod 9 is inserted into the second limiting hole 107, and the third limiting rod 12 is inserted into the third limiting rod 12. The bent part A of the spring is placed between the first limiting rod and the second limiting rod 9. At this time, the limiting plate 5 and the first limiting rod 8 are on the same side of the spring. The limiting plate 5 is pressed against the bent part A of the spring. By rotating the handle 4, it moves towards the third limiting rod 12. The limiting plate 5 pushes the bent part A of the spring to bend around the second limiting rod 9 as the center.

[0034] Select first limiting rods 8 and second limiting rods 9 of different diameters according to the size and bending radius of the spring. Place the second limiting rod 9 into different second limiting holes 107 according to the bending angle of the spring and select third limiting rods 12 of different diameters. Limit the bending part of the spring by limiting the limiting rods. The end of the limiting plate 5 is used to limit and tighten the retaining ring, and the limiting groove is used to limit and tighten the round spring.

[0035] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
