Translational vulcanizer

Abstract

The present invention relates to a translational vulcanizer, including a translational mechanism, a translational frame, an upper vulcanizing chamber, a lower vulcanizing chamber, a device for assembling and disassembling a tyre, a radial parting mould, a stand body, a second stand, a switching mould oil cylinder and a translational oil cylinder. The translational frame and the switching mould oil cylinder are arranged on the translational mechanism, the upper vulcanizing chamber is arranged on a piston rod of the switching mould oil cylinder, the lower vulcanizing chamber is arranged on the stand body, and the device for assembling and disassembling the tyre is arranged on the second stand. The radial parting mould is divided into an upper mould and a lower mould, the lower mould is arranged in the lower vulcanizing chamber, and the upper mould is fixed below the upper vulcanizing chamber. Left and right supports of the translational mechanism are provided with three to five wheeled kinematic mechanisms locating below the support separately, and each wheeled kinematic mechanism is arranged on a wheeled guide rail fixed on the supports locating on the right and left sides of a stand component. the vulcanizer is used for vulcanizing a giant engineering tyre, has a stable and smooth operation by employing the wheeled kinematic mechanism, is not easy to break a movable member, reduces the cost and time for maintenance, and has a long service life.

Description

technical field [0001] The invention relates to a translation vulcanizer. Background technique [0002] In the process of producing engineering giant radial tires, the vulcanization process greatly improves a series of physical and mechanical properties of rubber such as modulus, elasticity, hardness, and tensile strength. The quality of tire vulcanization largely determines the quality of tires. performance. As the load capacity of construction machinery increases, the size of the tires used is also increasing. The lower body of the steam chamber of the translation vulcanizer is stationary, and the upper body of the steam chamber moves in translation with the frame, which is widely used for vulcanizing engineering radial tires. [0003] When the translational vulcanizing machine is used to vulcanize engineering giant radial tires, due to the huge volume of the mold, the volume of each part of the whole machine will also increase. High, the structure of the whole machine ...

AI Technical Summary

Problems solved by technology

For a translation vulcanizer mentioned in Chinese patent document CN200610026201.4, if the translation support has a large span, during the translation process, due to the asynchronous left and right translation cylinders, the support will generate large stress and deformation, which will seriously affect the operation of the whole machine. Stability and service life

During the vulcanization process of the steam chamber of the vulcanizer, the clamping force is as high as 3,000 to 3,900 tons, and the pressurization device is required to be stable and reliable. If multiple piston cylinders are used to pressurize together, stress differences will occur due to uneven force, which will shorten the life of the piston rod. Greatly reduced
