Method for installing explosion-proof plate on matched piece, namely flap of heavy-duty tyre

Abstract

The invention discloses a method for installing an explosion-proof plate (7) on a matched piece, namely a flap (6) of a heavy-duty tyre. The method comprises the following steps of: fixing the explosion-proof plate (7) through a support (9), supporting a supporting shaft (4), expanding a through hole of the flap (6) to the required diameter through the supporting shaft (4) by manually operating the pressing of a pressing mechanism, making the flap (6) slip, guiding the flap (6) to the seam allowance of the explosion-proof plate (7), and finishing installing the explosion-proof plate (7) on the flap (6) with the aid of a gland. When the method is operated, the method is not limited by places or energy media; a used tool has reasonable structure and light dead weight, and can move flexibly;meanwhile, the operation is simple and reliable; and the method is low in operating cost.

Description

Technical field [0001] The subject of the present invention is a method for installing a burst-proof plate on the supporting part of the truck tire-the cushion belt. The burst-proof plate has a slit that is turned outward, and its outer diameter is an interference fit with the through hole on the cushion belt. At the same time, the thickness of the through hole of the gasket is slightly greater than or equal to the width of the flange opening of the explosion-proof disk, especially the flange of the explosion-proof disk must pass through the hole of the gasket, so that the gasket is embedded on the explosion-proof disk in the thickness direction, that is, Install the explosion-proof disc on the pad. Background technique [0002] At present, the use of truck tires requires that the performance of the gasket at the valve has sufficient rigidity. In the traditional design, the solution is to increase the thickness of the corresponding part of the pad, or to specially add reinf...

Problems solved by technology

In the traditional design, the solution is to increase the thickness of the corresponding part of the pad, or to specially add reinforcement layer parts pasted to the corresponding part of the pad. These designs not only increase the cost, but also increase the difficulty of operation; in recent years, additional rigid materials—— - Explosion-proof sheet, that is, the metal steel sheet is inlaid on the hole of the gasket, the effect is better, and it is widely used now, but the installation of the explosion-proof disk, that is, the inlay of the gasket is a bottleneck problem. When the through-hole fit of the pad belt is a small interference, it can be manually operated without the help of a machine, that is, the pad belt is bent from the through hole and the explosion-proof piece is hard-fitted to complete the assembly; the assembly is easy, but the use effect is not good, and the explosion-proof during transportation The sheet has the defect that it is easy to fall off, and its use does not conform to the fine management of tire manufacturing

When the fit is a large interference, manual operation is still used, the assembly is difficult and the work efficiency is low; if machine operation is used, there will be a power source using a medium such as wind, and the operation location is also restricted by the power medium and cannot be changed at will. site, or need to increase the additional operation of transshipment products to adapt to the operation site; this method has the disadvantages of inflexible operation and high operating cost, but the explosion-proof disc is not easy to fall off during use, and the use effect is better
