Abstract
The invention discloses a production process of a large-sized plum-blossom wheel rim, which comprises the following steps: step 1, blanking, cutting a plate to form a circular embryonic plate; step 2, cutting in the middle of the circular embryonic plate to form a circular through hole , and cut and form a plurality of special-shaped holes around the circular through-hole, the initial body of the mounting block is formed between adjacent special-shaped holes, and a connecting ring is formed between the special-shaped hole and the circular through-hole; Step 3, the circular embryonic plate The outer circle is finished to make it match the inner side of the rim body; Step 4, weld the surrounding of the circular embryonic plate on the inner side of the rim body; An arc-shaped gap is formed between adjacent mounting blocks; step 6, drilling holes on the mounting blocks to form mounting holes. The production process of the large-sized plum-blossom rim of the invention can effectively reduce the deformation of the spokes during the welding process, ensure the accuracy of each part on the spokes, and eliminate the need for secondary processing.
Description
technical field [0001] The invention belongs to the technical field of wheel rims, and in particular relates to a production process of large-sized plum-blossom wheel rims. Background technique [0002] The rim (wheel rim), commonly known as the rim, is a component that installs and supports the tire around the wheel, and forms the wheel with the spokes. Rims and spokes can be integral, permanently attached or removable. [0003] The torx rim is a common style of rims. In the production process of large-scale torx rims, spokes with torx-shaped through holes need to be welded on the inner side of the rim, and holes are drilled on the spokes to form mounting holes. The traditional process is to pre-process the spokes, and then weld the spokes around the rim. Because the spokes will generate high temperature during the welding process, the spokes are easy to deform, which will cause the position of the mounting holes on the spokes to shift, resulting in the installation of the...
