Technical Field
The invention relates to the field of rubber machinery, in particular to a three-drum forming machine and a carcass drum station operation method thereof.
Background
In the continuous and continuous development of the expressway and the transportation industry in China, the all-steel truck radial tire forming machine is greatly developed as one of the most important devices for manufacturing all-steel truck radial tires. The equipment used in the market at present is a two-drum, three-drum and four-drum forming machine. The development of the two-drum forming machine is stopped due to low efficiency, and the four-drum forming machine has high efficiency but the price is multiple times of that of the three-drum forming machine. Although the three-drum forming machine breaks through in the aspects of production quality and efficiency at present, compared with a four-drum forming machine, the production efficiency is still to be further improved in the degree of automation compared with a semi-steel forming machine. Therefore, the forming process and the forming equipment of the all-steel radial truck tire must be improved and innovated greatly, and the development of the high-efficiency three-drum forming machine with high production efficiency, good formed tire blank quality, high automation degree and excellent cost performance becomes the urgent need of the current market.
A one-step forming machine for an all-steel-wire truck radial tire for forming a radial tire in rubber industrial machinery mainly comprises the following six parts: the tire-unloading system comprises a molding system, a feeding system, a workpiece-making conveying system, a calibration system, a tire-unloading system and an operating system. The tire bead is an important component of an all-steel radial tire, and one all-steel radial tire comprises a left tire bead and a right tire bead (steel wire ring). On an all-steel radial tire three-drum forming machine, two feeding modes are provided for tire beads of the tire. One of them is that the tire bead preselector is positioned at two sides of the tire body drum, before the composite member is attached, the tire bead is manually placed on the tire bead preselector at two ends of the tire body drum, and the tire bead is taken when the tire body drum is taken by the tire body drum transfer ring and is transferred onto the forming drum. The other mode is that the tire bead pre-setting device is positioned at the outer side of the tire body cylinder transfer ring, the tire bead is manually placed on the external tire bead pre-setting device, the tire bead is automatically transferred to the tire body cylinder transfer ring by the tire bead pre-setting device, the tire body cylinder transfer ring enters a tire body drum station before the cushion rubber is attached, the tire body cylinder is opened to be flat and wide, the tire body cylinder is taken after the cushion rubber is attached, and the tire body cylinder and the tire bead are transferred to the forming drum by the tire body cylinder transfer ring.
For the two modes, the first mode can keep the intermediate ring of the tire body cylinder transfer ring, so that the tire body cylinder transfer is more reliable and has wider application, but because the beat time occupied by manual operation is about 7s, the requirements on the efficiency of the tire building machine are higher and higher, and the market technical requirements that the single tire cycle time is shorter and shorter are not satisfied. In the second mode, because the tire bead is arranged on the outer side of the tire body cylinder transfer ring by using the spare time, the takt time is saved, and the efficiency target is obviously improved; however, the tire bead transfer scheme requires that the tire body cylinder transfer ring has no intermediate ring or only one lower magnet arc plate, so that the tire body cylinder is easy to have no magnet adsorption in the tire body cylinder transfer process, and can collapse due to gravity, and particularly, the tire bead transfer scheme is easy to cause poor tire body cylinder transfer, poor tire dynamic balance data and other tire quality problems under the working conditions of large-size tires or long waiting time of the tire body cylinder carried by the tire body cylinder transfer ring.
The problems to be solved by the invention are as follows: the layout of each system is arranged more reasonably, a time overall method is adopted, the beat step sequence is optimized, and the processes of the fitting of the tire body cylinder assembly, the fitting of the tire bead upper ring, the fitting of the belted layer composite and the like are carried out simultaneously, so that the production process is simplified, the single tire cycle time is shortened, and the participation of people is reduced.
