Pressurization mechanism of hydraulic vulcanizer

Abstract

The invention discloses a pressurizing mechanism of a hydraulic vulcanizer, which comprises a hollow oil cylinder, the piston of which is sleeved on the lower rod of the hydraulic vulcanizer, the upper end of the piston approaches or contacts the base of the hydraulic vulcanizer without hindrance, and the piston A snap ring is arranged at the lower end, and the snap ring is fixedly sleeved on the pull-down rod, and at the same time, the snap ring is also fixedly connected with the piston. Compared with the prior art, the present invention can effectively improve the disassembly efficiency of the lower rod, thereby improving the work efficiency of the lower rod and the pressurizing mechanism.

Description

technical field [0001] The invention relates to a pressurizing mechanism in the field of tire vulcanizing equipment, in particular to a pressurizing mechanism of a hydraulic vulcanizing machine. Background technique [0002] The pressurizing mechanism is a device applied to the pull rod of the tire vulcanizer, and its function is to provide the driving force for the upward movement of the pull rod when the upper and lower pull rod is clamped. figure 1 Shown is the structure of the pressurizing mechanism of a hydraulic vulcanizing machine commonly used now. The hollow cylinder 1 is generally used in the pressurizing mechanism now. The upper and lower ends of the piston 11 of the hollow cylinder 1 are provided with upper snap rings 12 and The lower snap ring 13, the advantage of the pressurizing mechanism of this structure at present is that it takes up less space, and the disadvantage is that it is inconvenient to install and disassemble the lower rod 2. This is because when ...

Problems solved by technology

figure 1 Shown is the structure of the pressurizing mechanism of a hydraulic vulcanizing machine commonly used now. The hollow cylinder 1 is generally used in the pressurizing mechanism now. The upper and lower ends of the piston 11 of the hollow cylinder 1 are provided with upper snap rings 12 and The lower snap ring 13, the advantage of the pressurizing mechanism of this structure at present is that it takes up less space, and the disadvantage is that it is inconvenient to install and disassemble the lower rod 2. This is because when disassembling the lower rod 2, it first needs to be disassembled Drop the hollow oil cylinder 1, and then remove the upper snap ring 12 to pull out the lower rod 2

This inconvenience is particularly evident in the field of use. Because the space where the vulcanizer is placed is generally narrow and the pressurized oil cylinder is relatively heavy, lifting tools cannot be used. In order to ensure positioning accuracy and personnel safety, special tools must be used to disassemble. , greatly affect work efficiency
