Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

Referring to fig. 1 and 2 together, fig. 1 is a schematic view of a durable spoke nipping mold according to an embodiment of the present application; fig. 2 is a schematic view of a first clamping die according to an embodiment of the present application. As shown in the figure, a durable spoke clamp die comprises a first clamp die 10, wherein the first clamp die 10 is in a cuboid shape and is provided with four first reference surfaces which are up, down, left and right; first positioning grooves 11 respectively arranged at the center of the first reference surface, wherein spokes are embedded in the first positioning grooves 11; support nails 12 respectively disposed at both sides of the first positioning groove 11; a second clamping die 20, wherein the second clamping die 20 is rectangular and is provided with four second reference surfaces which are up, down, left and right; the second positioning grooves 21 are respectively arranged at the center of the second reference surface, the second positioning grooves 21 correspond to the first positioning grooves 11, and spokes are clamped; and the support ribs 22 are respectively arranged at two sides of the second positioning groove 21, and the support ribs 22 are not in contact with the support nails 12.

In an embodiment of the present invention, the first clamping mold 10 and the second clamping mold 20 are rectangular, and the first positioning groove 11 and the second positioning groove 21 are respectively disposed on the four sides of the upper, lower, left, and right sides of the first clamping mold, and cooperate with each other to clamp the spoke-shaped material together, thereby completing the subsequent bending operation. The supporting nail 12 and the supporting rib 22 are further positioned to complete the assembly between the first clamping die 10 and the second clamping die 20, and the supporting nail 12 and the supporting rib 22 are staggered with each other and are not in contact with each other, so that the mutual influence is avoided.

Preferably, the second clamping mold 20 has a guide installation groove 41 corresponding to the support pin 12; the first clamping die 10 has a guide groove 42 corresponding to the support rib 22; when the first clamping die 10 clamps the spoke with the second clamping die 20, the support pin 12 is inserted into the guide mounting groove 41, the support rib 22 is inserted into the guide groove 42, and the first reference surface and the second reference surface are mutually abutted. In the present embodiment, the guide mounting groove 41 corresponds to the support nail 12, and is fitted and positioned by the same. The guiding groove 42 is engaged with the supporting rib 22 for positioning. When the first clamping die 10 and the second clamping die 20 clamp the spoke, the positioning can be mutually enhanced, the spoke is prevented from being deviated during processing, and the product quality of the spoke is ensured.
