A tire molding heat curing machine

Abstract

The invention relates to a heat curing machine for tire molding, which comprises an operating table, a feeding table, and a drive control chamber. The feeding table is provided with a first feeding roller and a second feeding roller, and the operating table is provided with a sliding support Frame, multi-layer preheating and pressing device, a tire building drum is arranged between the sliding support frame and the multi-layer preheating and pressing device, and a rotating shaft is pierced inside the tire building drum, and one end of the rotating shaft pivots with the supporting frame on the sliding supporting frame The hole is embedded, and the other end of the rotating shaft is embedded with the roller connecting pipe provided in the multi-layer preheating and pressing device; the multi-layer preheating and pressing device is sequentially provided with a roller pressing device and a heating module electrically connected to the drive control cabin. The heating module adopts a heating resistance wire, and the inside of the heating resistance wire is provided with a ceramic protective sleeve. The invention provides a tire forming thermosetting machine capable of quickly laminating and pressing multi-layer sheets to form tire semi-finished products, and at the same time having the capability of heating and pre-pressing the tire semi-finished products for curing.

Description

technical field [0001] The invention relates to the field of mechanical production, in particular to the field of tire molding, in particular to a tire molding thermosetting machine. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. In 1845, R.w. Thomson, a civil engineer born in Scotland, invented the pneumatic tyres, and obtained a patent from the British government under the title of "Wheel Improvement for Carriages and Other Vehicles". On December 10 of the same year, the first pneumatic tire was born. Tires are usually installed on metal rims, which can support the vehicle body, buffer external impacts, realize contact with the road surface and ensure the driving performance of the vehicle. [0003] Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so...

Problems solved by technology

[0004] In the prior art, the production of tires is relatively complicated, and it is necessary to lay and wind the sheets layer by layer and then press and solidify them. However, the production of tires in the prior art is not convenient enough, and after being made into semi-finished tires, it is transferred to the curing process. In the process, the operation of preheating and pressing the multi-layer sheets of tire semi-finished products is missing. Without preheating and pressing, it is easy to leave an air gap between each layer of sheets, which will affect the molding effect of the tire during curing.

As a result, the quality of the finished tire casing is problematic, causing potential safety hazards during use; at the same time, after the tire semi-finished product is produced, it is generally necessary to remove the tire semi-finished product before proceeding to the next step, and it cannot be pushed to the pre-pressing device for pre-pressing processing
