Description

Technical Field

[0001] The utility model relates to the technical field of leveling molds, in particular to a spoke leveling mold with high stability. Background Art

[0002] The spoke is a device that protects the rim and spokes of the vehicle wheel. It is characterized by a pair of circular cover plates. The diameter of the cover plates is close to the diameter of the rim. There is a hole in the center of the cover plate that is larger than the wheel's rotating axis. There is an opening near the edge of the cover plate. There is an annular wheel plate on the edge of the cover plate. The curved surface of the wheel plate can fit tightly with the curved surface of the rim.

[0003] When processing wheel spokes, a leveling mold is often required. However, the leveling mold in the prior art has a relatively simple overall structure and cannot limit material deformation and flow. Therefore, when leveling the wheel spokes, the edges of the wheel spokes are curved, so the wheel spokes are prone to position slippage when they are squeezed, requiring multiple leveling operations, and the leveling effect is poor. Therefore, a highly stable wheel spoke leveling mold is desired. Utility Model Content

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a spoke flattening die with high stability.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a highly stable spoke flattening mold, comprising a lower mold and an upper mold, and further comprising:

[0006] A limiting mechanism, which is provided on the upper mold and is used to limit displacement of the spokes during leveling;

[0007] The limiting structure includes an adjusting ring, which is fixed to the outer periphery of the upper mold by bolts. A pressure ring assembly is installed at the bottom end of the adjusting ring, and a flattening piece is installed in the middle of the pressure ring assembly.

[0008] As mentioned above, a stop block is installed in the middle of the lower mold, and the top end of the stop block is slidably connected to the flattening member and abuts against the bottom of the upper mold.

[0009] As mentioned above, the bottom end of the inner wall of the pressure ring assembly is bent outward, and the pressure ring assembly is in compression contact with the outer edge of the spoke.

[0010] As mentioned above, the bottom surface of the flattening member is in extrusion contact with the surface of the spoke, and the outer periphery of the top surface of the lower mold is provided with rounded corners and adapted to the size of the spoke.

[0011] As mentioned above, the top of the flattening member is slidably connected to the upper mold.

[0012] Compared with the existing technology, this high-stability spoke flattening mold has the following beneficial effects:

[0013] 1. The present invention utilizes the curvature of the bottom of the pressure ring assembly so that when the upper mold moves downward, the pressure ring assembly will squeeze the outer edge of the spoke. Since the lower mold supports the bottom surface of the spoke, the pressure ring assembly can limit the positional movement of the spoke. At the same time, the bottom of the flattening piece will flatten the spoke, eliminating the need for multiple leveling operations and improving the leveling effect.

[0014] 2. The utility model can limit the upper mold through the stop block installed in the middle of the lower mold, so that the lower mold and the upper mold can be aligned. At the same time, the stop block can limit the downward movement distance of the upper mold, thereby preventing excessive extrusion between the lower mold and the upper mold.

[0015] Other advantages, objectives and features of the present invention will be described in part in the following description and will be apparent to those skilled in the art based on an examination of the following or may be learned from the practice of the present invention.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1-2 As shown, the utility model provides a spoke flattening mold with high stability, comprising a lower mold 1 and an upper mold 2, characterized in that it also includes:

[0021] A limiting mechanism, which is provided on the upper mold 2 and is used to limit the displacement of the spokes during leveling;

[0022] Among them, the limiting structure includes an adjusting ring 7, which is fixed to the outer periphery of the upper mold 2 by bolts 3. A pressure ring assembly 4 is installed at the bottom end of the adjusting ring 7, and a flattening piece 5 is installed in the middle of the pressure ring assembly 4.

[0023] Through the design of the pressure ring assembly 4, when the upper mold 2 moves downward, the pressure ring assembly 4 will squeeze the outer edge of the spoke and limit the position movement of the spoke. At the same time, the bottom of the flattening part 5 will flatten the spoke, eliminating the need for multiple leveling and improving the leveling effect.

[0024] like Figure 2 As shown, a stop block 6 is installed in the middle of the lower mold 1 , and the top end of the stop block 6 is slidably connected to the flattening member 5 and abuts against the bottom of the upper mold 2 .

[0025] The stop block 6 installed in the middle of the lower mold 1 can limit the upper mold 2, allowing the lower mold 1 and the upper mold 2 to be aligned. At the same time, the stop block 6 can limit the downward movement distance of the upper mold 2, thereby preventing excessive extrusion between the lower mold 1 and the upper mold 2.

[0026] like Figure 2 As shown, the bottom end of the inner wall of the pressing ring assembly 4 is bent outward, and the pressing ring assembly 4 is in press contact with the outer edge of the spoke.

[0027] The height of the adjusting ring 7 can be adjusted by the cooperation between the adjusting ring 7 and the upper mold 2 , so that the height of the pressure ring assembly 4 can be adjusted by the adjusting ring 7 , and further the stroke of the upper mold 2 can be freely adjusted.

[0028] like Figure 2 As shown, the bottom surface of the flattening member 5 is in press contact with the surface of the spoke, and the outer periphery of the top surface of the lower mold 1 is provided with rounded corners and adapted to the size of the spoke.

[0029] The spokes can be squeezed by the cooperation between the flattening piece 5 and the spokes, and the spokes can be supported by the lower die 1, which facilitates the flattening operation of the spokes.

[0030] like Figure 2 As shown, the top of the flattening member 5 is slidably connected to the upper mold 2.

[0031] Through the cooperation between the flattening piece 5 and the upper mold 2, when the pressure ring assembly 4 moves up and down, the flattening piece 5 can be adjusted to slide along the bottom of the upper mold 2, so that the movable stroke of the flattening piece 5 can be controlled.

[0032] Working principle:

[0033] First, place the spoke on the top of the lower mold 1, and then control the upper mold 2 to move downward by the hydraulic cylinder. At this time, through the curvature of the bottom of the pressure ring assembly 4, when the upper mold 2 moves downward, the pressure ring assembly 4 will squeeze the outer edge of the spoke, thereby limiting the displacement of the outer periphery of the spoke. Moreover, since the lower mold 1 supports the bottom surface of the spoke, and the bottom of the flattening piece 5 will flatten the spoke, there is no need for multiple leveling, thereby improving the leveling effect.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
