Spoke air hole machining mold

Abstract

The invention relates to the field of machining, in particular to a spoke air hole machining mold. The spoke air hole machining mold comprises an upper mold base, an upper mold body, a lower mold base and a lower mold body. The upper mold body and the upper mold base are connected in a matched manner. The lower mold body and the lower mold base are connected in a matched manner. An upper punch is arranged on the lower end face of the upper mold body. A lower punch is arranged on the upper end face of the lower mold body. A left elastic clamping plate and a right elastic clamping plate which are in sliding connection with the lower mold base are arranged on the lower mold base. Holes for the punches to penetrate are formed in the upper faces and the lower faces of the left elastic clamping plate and the right elastic clamping plate. The left elastic clamping plate is provided with a groove consistent with a spoke arc. A left protruding pin matched with a center hole of a spoke and left positioning pins matched with a spoke bolt hole are arranged on the upper face of the groove. The right elastic clamping plate is provided with a protruding groove matched with the left elastic clamping plate, and the groove is provided with right protruding pins and a right positioning pin. The spoke is vertically placed, the spoke is clamped and positioned through the left elastic clamping plate and the right elastic clamping plate, accordingly, vertical punching is carried out, and the spoke can be prevented from being abraded or deformed in the punching process.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a mold for processing spoke air holes. Background technique [0002] The spoke is a device to protect the rim and spokes of the vehicle wheel. The structure is a pair of circular cover plates. The diameter of the cover plate is close to the diameter of the wheel rim. There is a hole in the center of the cover plate that is larger than the rotation axis of the wheel. The part near the edge of the plate has an opening, the edge of the cover plate has an annular wheel plate, and the curved surface of the wheel plate can closely fit the curved surface of the wheel rim. With the rapid development of the automobile industry, the product quality of the spokes has also attracted much attention, and the spoke air holes are an important factor affecting the performance of the spokes. At present, each wheel factory is processing the air holes of the spokes by using the force between th...

Problems solved by technology

However, there is the following problem: in this patent, in order to punch holes, the spokes are fixed on the inclined wheel disc, and then punched by the punch of the upper die, but the downward force of the punch is relatively large, which is easy to The spoke part fixed on the wheel disc generates a huge impact force. At the same time, the wheel disc itself is relatively strong. Under the impact force of the punch, the spokes and the wheel disc are easy to cause the wear of the spokes, and it is easy to deform or lose the roundness of the spokes. Installed on the wheel There will be vibration up and down
