Irradiation-preheating tire vulcanizing device

Abstract

The invention relates to an irradiation-preheating tire vulcanizing device. According to the invention, a clamping mechanism at the lower end of the tire mounting mechanical hand of a conventional tire shaping and vulcanizing machine is dismounted, the irradiation-preheating tire vulcanizing device is mounted at the fixed disk of the tire mounting mechanical hand; the device mainly comprises bolts, hydraulic controllers, pull rods, sliding blocks, travel switches, a support frame, arc-shaped heating plates and guiding tracks. According to the invention, the period for preparation of tire vulcanization is fully used, and the tires are heated through a infrared heating manner, so that tires have a certain temperature before formal vulcanization, thereby shortening vulcanizing time in the machine and improving vulcanization working efficiency. The device has can freely adjust and replace the preheating device according to the different sizes of tries, so the device is excellent in applicability and suitable for processing and manufacturing tire products with different types; in addition, a tire centring device is arranged, so the overlapping of the tire center and support frame center can be ensured, and the tire vulcanization uniformity is improved greatly, and tire shaping and vulcanizing quality is improved finally.

Description

technical field [0001] The invention relates to the field of tire shaping vulcanization, in particular to a high-efficiency and energy-saving tire vulcanization method for irradiation preheating, which is suitable for processing and manufacturing various types of tire products. Background technique [0002] With the rapid development of automobile enterprises, the requirements for the quality of automobile tires are getting higher and higher. As an important process in tire processing, vulcanization aims to optimize the physical and mechanical properties of various parts of the tire. Therefore, the uniformity of vulcanization has a great influence on the performance of tires. Since the tire is a thick rubber product and is a poor conductor of heat, when the inside of the tire reaches positive vulcanization, the outer surface of the tire has already been over-vulcanized. This phenomenon of uneven vulcanization greatly affects the quality of the tire. [0003] Raising the in...

Problems solved by technology

[0004] The purpose of the present invention is to design a tire setting vulcanization radiation preheating device to make full use of the tire vulcanization preparation for the defects that the time before the vulcanization of the existing tires cannot be fully utilized, resulting in low tire vulcanization efficiency and serious energy waste. During this period of time, it is preheated by infrared heating, so that it has a certain initial temperature before it is officially vulcanized, so that the vulcanization time in the machine can be shortened, and the vulcanization work efficiency can be improved. In addition, infrared heating uses electromagnetic radiation heat The principle of heat transfer directly heats the object, thereby avoiding the energy loss caused by heating the heat transfer medium. Compared with the steam heating method, it is beneficial to save energy, and the preheating device can be freely adjusted and replaced according to the different sizes of the tire, so that the device has Good applicability, at the same time set the tire centering device to ensure that the center of the tire coincides with the center of the support frame, thereby greatly improving the uniformity of tire vulcanization, and finally improving the quality of tire vulcanization
