Integrated balance block and molding process thereof

Abstract

The invention discloses an integrated balance block and a molding process thereof. The integrated balance block comprises a balance block body. The balance block body is provided with multiple pressing grooves and is cut into multiple connected sub-block bodies through the pressing grooves. Each pressing groove comprises an upper pressing groove body and a lower pressing groove body. The upper pressing groove bodies and the lower pressing groove bodies are oppositely arranged on the upper end face and the lower end face of the balance block body. The bottom faces of the upper pressing groove bodies and the bottom faces of the lower pressing groove bodies are stretched and extruded to form slice type connection belts. Each slice type connection belt comprises a first tearing belt, a second tearing belt and a connection belt body located between the first tearing belt and the second tearing belt. The portions, located at the two ends of each pressing groove, on the two sides of the balance block body are provided with avoiding grooves respectively. The molding process of the integrated balance block includes the steps of firstly, pressing groove molding, secondly, avoiding groove molding and thirdly, cutting off. By the adoption of the integrated structure design, the cut-off amount of waste is small, the material utilization rate is high, the appearance of the steel balance block can be improved, and following process operation convenience can be improved.

Description

technical field [0001] The invention relates to the technical field of balance weights, in particular to an integral balance weight and its forming process. Background technique [0002] With the improvement of road conditions in our country and the rapid development of automobile technology, the speed of vehicles is also getting faster and faster. If the quality of the car wheels is uneven, it will not only affect the comfort of the car during this high-speed driving process, but also increase the abnormal wear and tear of the car tires and suspension system, increase the difficulty of controlling the car during driving, and cause driving problems. not safe. In order to avoid this situation, before installation, the wheels must go through a dynamic balance test with a special equipment - a wheel dynamic balancing machine. Appropriate counterweights are added to the places where the weight of the wheels is too small to keep the wheels in dynamic balance under high-speed rot...

AI Technical Summary

Problems solved by technology

The existing steel material paste balance block is composed of multiple individual small blocks with adhesive on the back. Due to the limitation of the stamping process, the slope of the fracture layer of the cut surface of this small block is inconsistent, and the aesthetics is not high. Another main aspect is that this kind of block stamping process needs to cut waste materials, and the material utilization rate is only 60% to 65%.
