Intelligent double-mould hydraulic tire curing press and mould adjusting method

Abstract

The invention discloses an intelligent double-mould hydraulic tire curing press comprising a guide rod 1, a mould opening and closing oil cylinder 2, a mould locking mechanism 3, a pressurizing oil cylinder 4, a lower plate 5, a lower oil cylinder support 6, an upper plate 8, a locking nut 9, an upper oil cylinder support 10, a support 11 and a displacement detection device 12. A stroke and a stress application action for completely closing moulds, required by different heights of the moulds, are replenished through the extending stroke of a piston rod of the pressurizing oil cylinder 4, and the set position heights are detected by using an electrical control system PLC (Programmable Logic Controller) and a displacement detecting device, so that digital, intelligent and automatic mould adjustment without a mould adjusting mechanism or artificial adjustment is realized. The intelligent double-mould hydraulic tire curing press is convenient to mount and easy to maintain and has the effects of improving the accuracy in closing an upper mould and a lower mould and the quality of a tire, reducing the manufacturing cost, saving the mould adjusting time and greatly increasing the production efficiency.

Description

technical field [0001] The invention relates to a tire vulcanizer, in particular to an intelligent dual-mode hydraulic tire vulcanizer and a mold adjustment method thereof. Background technique [0002] With the continuous development of the automobile industry and the tire industry, higher and higher requirements are put forward for the quality of tires, which leads to higher and higher requirements for the processing accuracy, automation and intelligence of tire curing machines, and fierce industrial competition. It has brought problems such as cost and production efficiency to the tire vulcanizing machine. Simple and compact structure, simple and convenient operation, intelligence, easy maintenance, and improved production efficiency are the goals pursued by manufacturers and users of vulcanizing machines. [0003] The structure of the vulcanizing machine is a crucial factor for processing accuracy. At the same time, the structure and intelligence of the vulcanizer join...

AI Technical Summary

Problems solved by technology

However, this tire vulcanizing machine also has the following disadvantages: 1. Since the clamping mechanism and the pressurized oil cylinder are respectively installed on the upper beam and the base, when the mold is closed, it is easily affected by the machining accuracy of the guide rod. 1. The final clamping of the lower mold must move the upper mold and then push the lower mold, so that the centers of the upper and lower molds are centered, the centering accuracy is poor, and the centering repeatability is poor, thereby affecting the quality of the tire; 2. Due to The clamping mechanism and the pressurized cylinder are respectively installed on the upper beam and the base, so the installation of the clamping mechanism and the pressurized cylinder must be positioned at the same time during installation, and the cylinder body of the pressurized cylinder installed on the base sinks to the base, these It greatly increases the difficulty of installation and maintenance, which increases the cost of installation and maintenance; 3. The equipment is huge and the structure is complex. For example, the upper beam and the base are heavy box structures, which makes it difficult to manufacture the product and increases the production cost; 4. The tire is vulcanized The machine cannot automatically detect the moving position of the upper mold, and the intelligent system is low, resulting in long mold clamping time and low production efficiency
