Description
Technical Field
The invention relates to the technical field of processing and production of rims with different offset distances, in particular to rim unit processing equipment for two-piece spliced rims.
Background
The hub is the rotating part of the wheel core, which is connected with the inner profile steel of the tire through the upright post, namely, the metal part which supports the center of the tire and is arranged on the shaft. Also called rim, steel rim, wheels and tyre bell. The hub has various types according to the diameter, width, forming mode and materials.
The offset is commonly called as ET value, which refers to the distance between the hub bolt fixing surface and the geometric center line (the center line of the cross section of the hub), and is simply the difference between the hub middle screw fixing seat and the center point of the whole rim, and the popular point is whether the hub is retracted inwards or protruded outwards after being refitted. The ET value is positive for a typical car and negative for a few vehicles and some jeep. For example, a trolley with a deflection of 40, if it is replaced with ET45, will be more visually retracted into the wheel arch than the original hub. Of course, the ET value not only affects visual changes, but also has relation with steering characteristics of the vehicle and wheel positioning angles, and an excessively large offset value may cause abnormal abrasion of tires, easily wear bearings and even cannot be normally installed at all (the braking system and the hub rub against each other and cannot normally rotate). In most cases, the same version of the hub of the same brand will provide different ET values for selection. The existing hub production modes are gravity casting, forging and low-pressure precision casting, and are all integrated, and for hubs with different ET values, a production die is required for each hub with different ET values, so that the cost of a production enterprise is high; in order to save the production cost, the production enterprises have to standardize the production as much as possible, and the spoke patterns and the hub offset distances of hubs required by each customer are not identical, so in order to save the production cost, many hub production enterprises are already assembling the spokes and the rims into a complete hub after separately producing the spokes and the rims, and the mode can reduce certain production cost, but still needs different rim moulds for production due to different ET values of the hubs, so that the production cost is still higher. The ET value is different from the diameter size of the hub, and the diameter size of the hub is standard, so that the spoke can be produced in advance according to the corresponding diameter size of the hub, and can be directly spliced and fixed with the corresponding rim at the time; the ET value is not the standard value, and the requirements of different clients are different, so that rims with a certain diameter size and different ET values cannot be produced in a large quantity at one time, and rims with different ET values of each size respectively need corresponding dies, so that the use rate of the dies is low, and the production cost is still high. How to reduce the cost of producing rims of different ET values is a technical problem that the person skilled in the art always wants to solve.
