Forming device and tire forming method

Abstract

The invention discloses a forming device and a tire forming method. The forming device comprises a transversely-longitudinally orthogonal rail unit, a transmitting mechanism, a tire body fitting unit,a steel wire ring placement unit, a belt layer fitting unit, a forming unit, a shaping unit and a tire unloading mechanism; and the transversely-longitudinally orthogonal rail unit is divided into four areas, all the units are reasonably arranged, and connection between the units is built through the transmitting mechanism. The tire forming method comprises the steps that (1) a steel wire ring and a tire body fitting composite piece are bonded together and conveyed to the forming unit; (2) a belt layer composite piece is conveyed to the forming unit; (3) the tire body fitting composite pieceand the belt layer composite piece are compounded into a tire shell and conveyed to the shaping unit; and (4) the tire shell is wound with a tread to form a tire blank, and the tire blank is conveyedto the tire unloading mechanism to be unloaded. According to the forming device and the tire forming method, based on the basic demands that the technology procedure is not changed, and the product quality is improved, in order to meeting the requirements of clients, the equipment occupied area is decreased, and the equipment productivity is improved.

Description

technical field [0001] The invention relates to the field of tire manufacturing, in particular to a molding device and a tire molding method. Background technique [0002] Two kinds of equipment are mainly used in the molding process of OTR tires: one is a two-drum OTR tire building machine, and the other is a four-drum OTR tire building machine. [0003] Such as figure 1 As shown, the two-drum OTR tire building machine is an all-steel OTR tire building manufacturing equipment. This model is composed of two units-carcass / building unit and belt layer unit. Carcass / forming unit: used for laminating carcass composite parts, and at the same time, this unit also needs to receive the belt layer laminating composite parts manufactured by the belt layer unit, and complete the molding work; this unit is supplied by the main machine feeding system ( Contains feeding device and guide mechanism - conveying rubber for carcass fitting tooling), carcass / forming power system, carcass / form...

AI Technical Summary

Problems solved by technology

[0005] Disadvantages of the two-drum OTR tire building machine: 1. Since all rubber laminating and forming work are completed on the carcass / forming tooling, the production efficiency is low. Taking 23.5R25 (tread winding) as an example, shift production: 8-10 2. Because the surface of the carcass / forming tooling is designed as a capsule elastic tooling, it will have an adverse effect on the laminating accuracy and rolling quality; 3. Because the carcass laminating tooling adopts a triple sleeve telescopic structure, the diameters on both sides of the sleeve are different. etc. (with the center line as the dividing line, and the two sides are asymmetrical structures), which affect the quality of lamination. At the same time, during the rolling process, the phenomenon of "deviation" of the rubber material is prone to occur; 4. The layout position and occupied space of the winding system cause The space of the whole machine is wasted, which reduces the effective utilization rate of the equipment area

[0008] Disadvantages of the four-drum OTR tire building machine: 1. Because the scheme adopts the form of a rotary table, when the time used to complete the steps on the tooling on both sides of the rotary table does not match, it will cause "disorder" in the production process and affect production efficiency; 2. Occupies an area The area is large, and the forming tooling is installed on the rotary table to rotate back and forth, resulting in a lot of waste of area; 3. The number of operators is more than that of the "two-drum OTR tire building machine"-5 people; 4. The equipment occupies a large area and the number of personnel The moving distance of reciprocating and retrieving rubber materials is relatively long, which wastes effective operation time; 5. The replacement of tooling is slow (at least 3 tooling needs to be replaced); 6. The layout position and occupied space of the winding system cause part of the space waste of the whole machine, reducing the Effective utilization of equipment area; 7. There is no advantage in sales price—compared to "two-drum OTR tire building machine"
