Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheel hub production technology, specifically to a split spinning mold for multiple tire width specifications. Background Technology
[0002] Currently, wheel manufacturing in the market is transitioning from simple gravity casting and low-pressure casting to semi-low-pressure, semi-forged wheels, allowing for the combination of the low cost of cast wheels and the high performance of forged wheels. However, for rim forging, when customers require different tire ring widths, a single mold cannot cover all manufacturing needs. Different rim widths require additional casting molds and spinning forging molds of different specifications, resulting in higher production costs. Utility Model Content
[0003] The purpose of this invention is to provide a split-type spinning die for multiple tire widths. By disassembling the static die design in the existing spinning die into a split structure consisting of a shared spinning die body and an annular pad, different tire width specifications can be achieved when processing tire ring blanks with different tire width requirements. This expands the application range of the spinning die without having to replace the entire spinning die, thereby reducing the development and manufacturing costs of the spinning die.
[0004] To achieve the above objectives, this utility model provides a split spinning die for multiple tire width specifications, comprising:
[0005] The spinning die has a common body, and a holding groove is provided inside the common body. The spinning die can rotate along the horizontal plane.
[0006] An annular pad is detachably mounted on the common body of the spinning die;
[0007] The first moving mold is set in the holding groove and can move vertically to carry the tire ring blank;
[0008] The second moving mold is positioned above the first moving mold and can move vertically to cooperate with the first moving mold in clamping and pressing the tire ring blank.
[0009] Optionally, the spinning die has a mounting groove at the top of its common body, and the annular pad has a locking block at the bottom that mates with the mounting groove. The mounting groove and the locking block mate to fix the annular pad.
[0010] Optionally, the annular pad and the spinning die body are fixed together by screws.
[0011] Optionally, the bottom of the first moving mold and the bottom of the holding groove are attached together.
[0012] Optionally, a push cylinder is provided at the bottom of the holding tank, and a push rod is provided at the movable end of the push cylinder for pushing the first moving mold out of the holding tank.
[0013] Optionally, the top of the first moving mold rests on the annular pad and matches the shape of the annular pad.
[0014] The beneficial effects of this utility model are as follows: by splitting the static mold design in the existing spinning die into a split structure of a shared spinning die body and an annular pad, when processing tire ring blanks with different tire width requirements, by replacing the annular pad and the matching first moving die, it is possible to process tire ring blanks with different tire width specifications, thereby expanding the application range of the spinning die without having to replace the entire spinning die, thus reducing the development and mold making costs of the spinning die.

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0023] Please see Figure 1 First, it should be noted that the existing spinning die includes a left stationary die 1, a left moving die 2, and a right moving die 3. The left moving die 2 is fitted onto the left stationary die 1, and the tire ring blank 4 is fitted onto the left moving die 2. The right moving die 3 is positioned above the tire ring blank 4. By moving the right moving die 3 downwards to press the tire ring blank 4, and then rotating the left stationary die 1, the left moving die 2 and the tire ring blank 4 on it are rotated, thereby causing the spinning cutter set outside the die to process the tire ring blank 4.
[0024] Please see Figure 2 and Figure 3 A preferred embodiment of this application shows a multi-specification tire width shared split spinning die, comprising a spinning die body 5, an annular pad 6, a first moving die 7, and a second moving die 8. The spinning die body 5 has a receiving groove 51, and the spinning die can rotate horizontally. The annular pad 6 is detachably mounted on the spinning die body 5. The first moving die 7 is disposed within the receiving groove 51 and can move vertically, serving to support the tire ring blank 4. The second moving die 8 is disposed above the first moving die 7 and can move vertically, serving to cooperate with the first moving die 7 to clamp and press the tire ring blank 4.
[0025] According to the embodiment of this utility model, by splitting the static mold design in the existing spinning die into a split structure of a common spinning die body 5 and an annular pad 6, when processing tire ring blanks 4 with different tire width requirements, by replacing the annular pad 6 and the matching first moving die 7 that match the tire width requirements, the tire ring blanks 4 can be processed with different tire width specifications, thus expanding the application range of the spinning die without having to replace the entire spinning die, thereby reducing the development and mold making costs of the spinning die.
[0026] It should be noted that, since the mold of this application can be used for tire ring blanks 4 with different tire width requirements, during the production of wheel hub tire ring blanks, it is necessary to cast tire ring blanks that conform to the maximum tire width to ensure that the tire ring blank 4 has sufficient raw materials and can meet the qualification standard when spun to the maximum tire width. When making tire ring blanks 4 with smaller tire widths, excess material can be removed after being spun by a spun die. At the same time, the design of replacing the annular pad 6 is to change the height of the spun die common body 5 (i.e., the original left stationary die 1) by replacing the annular pad 6, so that the spun die can be used to process rims with different tire widths. As the height of the spun die common body 5 changes, the first moving die 7 also needs to be replaced accordingly to ensure that the bottom of the first moving die 7 fits the bottom of the receiving groove 51. The spun die of this application is mainly used for the spun production of two-piece welded wheel hubs (i.e., wheel rim and spokes are separate).
[0027] The following detailed description uses specific examples:
[0028] Please see Figure 3 The spinning die's common body 5 has a mounting groove 52 at its top, and the annular pad 6 has a locking block 61 at its bottom that mates with the mounting groove 52. The mounting groove 52 and the locking block 61 engage to secure the annular pad 6. The annular pad 6 and the spinning die's common body 5 are fixed together with screws. The locking block 61 engaging with the mounting groove 52 ensures a more secure installation of the annular pad 6, and the screw connection facilitates the replacement of annular pads 6 with different tire widths.
[0029] Please see Figure 2 The bottom of the first moving mold 7 is fitted against the bottom of the holding groove 51, and the top of the first moving mold 7 rests on the annular pad 6 and matches the shape of the annular pad 6. The design of the bottom of the first moving mold 7 fitting against the bottom of the holding groove 51 increases the friction between the first moving mold 7 and the holding groove 51, allowing the first moving mold 7 to rotate with the spinning die sharing the body 5, preventing relative displacement between the two and affecting the spinning production of the tire ring blank 4. The top of the first moving mold 7 rests on the annular pad 6 and matches the shape of the annular pad 6, ensuring that the surface supporting the tire ring blank 4 remains flat, thereby ensuring the stability of the tire ring blank 4 during spinning production.
[0030] Please see Figure 3The bottom of the holding tank 51 is equipped with a push cylinder 511, and the movable end of the push cylinder 511 is equipped with a push rod 512, which is used to push the first moving mold 7 out of the holding tank 51. After the tire ring blank 4 is spun, the first moving mold 7 is pushed out of the holding tank 51 by the push cylinder 511 so as to drive the spun wheel rim to separate from the spun mold common body 5 for easy demolding.
[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
