Hydraulic rubber air spring capsule-free vulcanizing machine and vulcanizing method

Abstract

The invention discloses a hydraulic rubber air spring capsule-free vulcanizing machine and a vulcanizing method. The vulcanizing machine comprises a base, an upper cross beam, and stand columns connected between the base and the upper cross beam. An upper plate capable of moving up and down on the stand columns is arranged on the middle upper parts of the stand columns. A lower plate is arranged on the base. A die locking hydraulic cylinder is mounted on the upper cross beam. A plunger lever at the lower end of the die locking hydraulic cylinder is connected with the top of the upper plate. Alocking device is connected below the upper plate. The lower plate is provided with a split type vulcanizing die. The split type vulcanizing die comprises a left sub-die, a left die, a middle die, a right die, and a right sub-die. The left die, the middle die, and the right die are each composed of two semi-dies opening and closing in an up and down mode. One ends of the two semi-dies are hinged,and the other ends of the two semi-dies can be opened and closed. A steam inlet is formed in the left sub-die or the right sub-die. The vulcanizing machine is simple in operation, improves vulcanizingefficiency, solves the problem of uneven heating of an air spring in vulcanizing, and is high in automation degree.

Description

technical field [0001] The invention relates to a rubber vulcanization equipment, in particular to a hydraulic rubber air spring bladderless vulcanizer and a vulcanization method. Background technique [0002] At present, the rubber vulcanization equipment is outdated and backward, and there is a lack of dedicated rubber air spring vulcanization equipment. The existing air spring vulcanizers have low degree of automation, low efficiency and high energy consumption. The mold used in the vulcanizing machine needs to be removed from the vulcanizing machine after each vulcanization, and needs to be cooled with cold water. The assembly of the mold requires the cooperation of two people, which consumes a lot of time, and the labor intensity of the workers is high. The quality of the vulcanized product is qualified. low rate. [0003] The existing rubber air spring vulcanization process mainly uses a capsule as the inner bag. Such as patent CN 102756444A, when vulcanizing the un...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of this method of vulcanization are: 1. The heat in the vulcanization needs to be transferred to the rubber air spring through the bladder, and a set of special equipment is required to manufacture the bladder. During the transfer process, there will be heat delay and energy waste, resulting in excessive vulcanization time of the rubber air spring. Long, low vulcanization efficiency and serious waste of resources; 2. It needs to consume a large amount of high-quality rubber to manufacture capsules, and it needs to be equipped with a set of special equipment to manufacture capsules, which increases the cost of vulcanization of rubber air springs to a certain extent; 3. Utilization The capsule molds the rubber air spring, which will cause uneven expansion, which will have a certain impact on the life and use of the rubber air spring
