Tire bead straightening machine

Abstract

The invention discloses a tire bead straightening machine. The tire bead straightening machine comprises a straightening machine frame. A supporting rack and a tire straightening roller are arranged on the straightening machine frame. A heating and heat-preservation system is arranged in the tire straightening roller. A tire clamping mechanism is arranged on the supporting rack and comprises an upper tire clamping rod and a lower tire clamping rod. The tire straightening roller is composed of an upper steel ring and a lower steel ring. Oblique sliding blocks are arranged on the inner side of the upper steel ring and the inner side of the lower steel ring. A pushing plate is arranged at the bottom end of each oblique sliding block. A pushing block is arranged between the two pushing plates.A pushing rod is connected to the pushing block. According to the tire bead straightening machine, the pushing block is driven by the pushing rod to move so as to control the distance between the upper steel ring and the lower steel ring, and then a proper pressure is applied to a to-be-straightened tire bead of a tire placed on the tire straightening roller according to a specified method. Poweris supplied to the heating and heat-preservation system through a power supply system, so that the heating and heat-preservation system is made to generate heat to bake and straighten the tire bead of the tire; and the degree of straightening can be controlled, so that the problem of non-uniform stress in the tire is indirectly solved.

Description

technical field [0001] The invention relates to the technical field of tire bead, in particular to a tire bead straightening machine. Background technique [0002] The bead of the tire is the part that meets the rim. The aspect ratio of modern car tires is mostly between 50 and 70. The smaller the value, the flatter the tire shape. As the vehicle speed increases, in order to lower the car's center of gravity and axle, the diameter of the tires continues to shrink. In order to ensure sufficient carrying capacity and improve driving stability and grip, the width of tires and rims has to be continuously increased. Therefore, the cross-sectional shape of tires develops from the original approximate circle to the flattened oval. Therefore, the requirements for the correcting steps of the tire bead are becoming more and more stringent, and after the tire is manufactured, the problem of uneven stress will inevitably occur. At this time, it is necessary to use a straightening machi...

Problems solved by technology

Therefore, the requirements for the correcting steps of the tire bead are becoming more and more stringent, and after the tire is manufactured, the problem of uneven stress will inevitably occur. At this time, it is necessary to use a straightening machine for correction. Most of the existing tire corrections use manual grinding. The labor intensity is high, the efficiency is low, the operating environment is harsh, and the dust pollution is serious. The appearance of the tire will be damaged during the correction process. The adjustment effect and speed of the uniformity of the bead are unstable, and it depends more on the actual experience of the operator. Therefore, we propose a tire bead straightening machine for solving the above problems
