Plane carcass puncturing device

Abstract

The invention relates to a plane carcass puncturing device which comprises a heating mechanism, a longitudinal moving mechanism, a transverse moving mechanism, a carcass stabilizing puncturing mechanism and a machine frame. The heating mechanism comprises a high-frequency heater, the transverse moving mechanism is located on the longitudinal machine frame, the carcass stabilizing puncturing mechanism is fixedly connected with the transverse machine frame and comprises a puncture mechanism and a carcass stabilizing mechanism, the puncture mechanism is located above a carcass, and the carcass stabilizing mechanism is located below the carcass; when a pricking needle is in contact with the carcass, a bearing plate is positioned below the carcass and is in contact connection with the carcass,so that the carcass is in a stable state; pricking needle assemblies are arranged in a dot-matrix mode, it can be guaranteed that one or more holes are pricked in the gap between every two evenly-distributed steel wire harnesses in one-time pricking action, and the technical requirement for tire body pricking is met; and a guide air cylinder provides power for the pricking needle, the pressure isstable and controllable when the pricking needle makes contact with a steel wire, and the steel wire harness cannot be damaged in the pricking process.

Description

technical field [0001] The invention belongs to the technical field of rubber tire molding, and relates to a puncture device, in particular to a plane carcass puncture device. Background technique [0002] The rubber tire is composed of tread, carcass and inner liner. The tread and inner liner are all rubber. The carcass is the tire skeleton, which is composed of rubber and steel wire harnesses. Before, the carcass is in the shape of long cord on the forming machine. During the rolling forming process of the carcass and the inner liner (the initial tire building structure: the carcass is on the outer layer, and the inner liner is on the inner layer), air bubbles appear between the carcass and the inner liner. , if it is not discharged in time, it will have a serious impact on the quality of the tire; therefore, in order to discharge the air bubbles, it is necessary to puncture a number of holes on the carcass; The strength cannot be precisely controlled, and the steel wire ...
