Novel pressurizing mechanism for hydraulic tire vulcanizing machine and hydraulic tire vulcanizing machine

Abstract

The invention discloses a novel pressurizing mechanism for a hydraulic tire vulcanizing machine. The novel pressurizing mechanism comprises a pressurizing oil cylinder, an upper pull rod, a lower pull rod assembly and a locking / unlocking device, wherein the pressurizing oil cylinder comprises a first piston rod or comprises the first piston rod and a second piston rod; the lower pull rod assembly comprises a lower pull rod, and the lower pull rod is locked with or separated from the upper pull rod through axial reciprocating rotation; the locking / unlocking device is connected with the lower pull rod and used for driving the lower pull rod to rotate in a reciprocating mode in the circumferential direction. The lower pull rod is connected with the piston rod outside the pressurizing oil cylinder, so that the length of the lower pull rod can be effectively shortened, the outer diameter of the piston rod can be reduced, the tension of a single oil cylinder is increased, the configuration number of the pressurizing oil cylinders is reduced, and the configuration cost of the pressurizing mechanism is remarkably reduced; and the lifting synchronism and stability of the pressurizing oil cylinder can be conveniently controlled.

Description

technical field [0001] The invention relates to the technical field of vulcanization equipment, in particular to a novel pressurizing mechanism for a hydraulic tire vulcanizer and a hydraulic tire vulcanizer. Background technique [0002] With the development of society and the increasingly rich living standards of people, especially since the 21st century, the automobile industry has been in a stage of vigorous development, and has driven the lasting prosperity of related industries. As one of the important accessories for automobiles, the development of tires is particularly eye-catching. , because the safety performance of the tire directly determines the safety factor of the car, which in turn affects the overall performance of the car. Because of this, the innovation and progress of tire production equipment has always been the focus of attention of technicians in the industry, among which tire vulcanizers are is a typical representative of it. [0003] In the prior ar...

Problems solved by technology

[0005] Nowadays, the pressurization mechanism generally adopts a pressurized cylinder with a double-rod structure. The piston rod is hollow, and the lower rod penetrates the pressurized cylinder through the hollow piston rod, which causes the outer diameter of the piston rod to be too large, resulting in a decrease in the tension of the piston rod. Small, the pressurization pressure of the pressurization mechanism has to be satisfied by increasing the bore and the number of configurations of the pressurization cylinder in the axial direction. The configuration cost and maintenance cost of the pressurization mechanism have always been high, and the more pressurization cylinders, The more difficult it is to control the synchronization of the pressurization mechanism
