Double-station multi-level hydraulic capsule tire-forming vulcanizer

Abstract

The invention relates to a double-station multi-level hydraulic capsule tire-forming vulcanizer. A stand is separated into a left station and a right station by a middle column, either station is internally provided with a set of hot-plate device which comprises devices sequentially arranged from top to bottom, i.e. a set of upper hot-plate device, at least one set of middle hot-plate device and a set of lower hot-plate device which form a multi-level structure, the upper hot-plate devices in the two stations are connected through an upper bracket arm, the middle hot-plate devices in the two sections are connected through a middle bracket arm, a plunger of a man oil cylinder is fixedly connected with a lower tray, a final-stage piston rod of a multi-level oil cylinder is fixedly connectedwith the upper bracket arm, and a middle-level piston rod of the multi-level oil cylinder is fixedly connected with the middle bracket arm. The invention opens and closes a die by adopting the lower multi-level oil cylinder, locks the die by the match of the lower short-stroke plunger-type main oil cylinder and the upper die-locking device and has the advantages of low operation and manufacture costs, small floor area, low labor intensity, good environmental protection, high safety, humanized operation, and the like.

Description

technical field [0001] The invention relates to the field of vulcanization of polymer materials such as rubber and plastics, and is particularly suitable for the vulcanization of tires in the tire industry, in particular to a double-station multi-layer hydraulic bladder tire vulcanizer. Background technique [0002] The existing tire vulcanizing machines generally have the following two types: [0003] One is a single-layer double-mode or single-layer four-mode hydraulic bladder shaping vulcanizer. This kind of vulcanizing machine has a high degree of automation and relatively simple operation. You only need to manually load the tire blank and press the button to realize: one-time shaping, fast mold closing, mold closing to the limit, secondary shaping, continuous mold closing, closing A series of actions such as mold limit, mold clamping, internal pressure entry, vulcanization, vulcanization time, internal pressure discharge, discharge time, vacuuming, mold opening, mold o...

AI Technical Summary

Problems solved by technology

The equipment of this kind of vulcanizing machine is relatively simple, but when it is put into 3-6 layers of molds one by one after manual shaping, its height is relatively superimposed on each layer of about 300mm (the height of the first layer is 600mm+(280mm-300mm range), and so on). According to the human body mechanics, when you reach the third and fourth floors, you must step on the steps. The degree of humanization is not high, the labor intensity of the operators is high, and the degree of automation is poor.

Because this kind of vulcanizing machine adopts the structure of the plunger cylinder, and each station is opened and closed by a long-stroke cylinder, the cylinder can only be placed underground, and trenches or holes must be dug to put it underground, and it cannot It is suitable for floor use, which increases the engineering cost of the vulcanization workshop
