Tire vulcanizer shaping pressure control device

Abstract

The invention discloses a forming pressure control device for a tire vulcanizer. The forming pressure control device is characterized in that the output signal of a PLC is converted into a gas pressure signal through an electric appliance converter to be connected with the control gas source interface of a balance valve, a stop valve Y2 is connected between a stop valve Y1 and the inlet of a capsule, the outlet of the stop valve Y1 is connected with the inlet II of the stop valve Y2, the outlet of the stop valve Y2 is connected with the inlet of the capsule, and the control gas source interface of the stop valve Y2 is connected with an electromagnetic valve YX2; a stop valve Y5 is connected between the capsule and the stop valve Y3, the control gas source interface of the stop valve Y5 is connected with an electromagnetic valve YX4, the outlet of the stop valve Y5 is connected with the PLC through a pressure transmitter, and the electromagnetic valve YX2 and the electromagnetic valve YX4 are connected with the PLC. The forming pressure control device has the advantages that the device is convenient in control, detection and recording, simple in structure, precise in control and detection and convenient to maintain, forming pressure is controlled by the PLC through the balance valve, and the PLC gives out corresponding alarm information when the forming pressure is excessively high or low.

Description

technical field [0001] The invention relates to a tire vulcanizing machine, in particular to a tire vulcanizing machine setting pressure control device, in particular to a tire vulcanizing machine setting pressure control device which is convenient to control, detect and record. Background technique [0002] When the tire vulcanizing machine is working, the tire blank is put into the vulcanizer by the tire loading manipulator, the first setting pressure enters the capsule, and then the upper ring drives the capsule down, the first setting pressure makes the capsule fill the tire blank, and then the tire is loaded The manipulator rotates out, and the host starts to close the mold. When the main engine closes the mold until the upper mold is about to touch the lower mold, the first setting is converted to the second setting until the main engine closes the mold and stops, and the setting pressure ends. At present, the size of the first setting pressure and the size of the sec...

AI Technical Summary

Problems solved by technology

At present, the size of the first setting pressure and the second setting pressure are manually adjusted and set by precision pressure regulating valves, and the degree of automation is low.

During this process, the setting pressure is displayed by the pressure gauge. When the setting pressure is too high or too low, there is no alarm prompt, and there is no record of the setting pressure data. When the tire has quality problems during the setting process, it is generally judged by the experience of the craftsman and cannot Provide accurate judgment and analysis of problems in the tire shaping process
