Triangle rubber strip double-acting pressure exhausting line device for all-steel truck radical tire

Abstract

The invention discloses a triangle rubber strip double-acting pressure exhausting line device for an all-steel truck radical tire and relates to the technical field of tire manufacturing. The device comprises a base, an upper embossing gear and a lower embossing gear. Supporting frames are assembled on the two sides of the upper surface of the base correspondingly. A pneumatic pressure reducing valve is arranged above a pneumatic hand-operated reversing valve. An installing frame is arranged above the base in a suspending manner. A polishing shaft transversely penetrates through the middle ofthe installing frame. Screw rods are arranged on the upper side and the lower side of the polishing shaft correspondingly in parallel. A hand wheel is arranged on one end of each screw rod. An air cylinder is fixed to the inner side of the installing frame. A first air cylinder swing base is connected to the moving end of the bottom of the air cylinder. The upper embossing gear and the lower embossing gear are installed on a third air cylinder swing base in a sleeving manner. According to the triangle rubber strip double-acting pressure exhausting line device for the all-steel truck radical tire, a set of triangle rubber strip pressure exhausting line device replaces two sets of triangle rubber strip pressure exhausting line device, and therefore the purposes of saving equipment space andreducing the equipment cost are achieved.

Description

technical field [0001] The invention relates to the technical field of tire manufacturing, in particular to an all-steel radial tire apex double-acting compression and exhaust line device. Background technique [0002] The carcass cords are arranged in the meridian direction (arranged at 90° or close to 90° to the centerline of the crown), and the tires with cords arranged almost in the circumferential direction to tighten the carcass are called radial tires. This is also the fundamental difference between radial tires and bias tires. In the field of tires, all-steel tires are mostly large tires, the so-called all-steel truck tires, and semi-steel tires are mostly small tires. [0003] The apex plays a buffer and support role in the tire as a whole. At the same time, as a medium for connecting the steel ring with other components, the apex pressure exhaust line has become a necessary production process for various tire manufacturers. [0004] The principles of the pressure ...

AI Technical Summary

Problems solved by technology

[0004] The principles of the pressure and exhaust line devices of various tire manufacturers are basically the same. They all rely on embossed gears to press grooves of a certain depth on the surface of the parts to achieve the purpose of exhausting. However, their forms are different. Some manufacturers use manual Devices that rely on gravity to apply pressure, and some are manually operated by pneumatic cylinders, but these manufacturers place embossed gears with different widths on two sets of pressure and exhaust line devices, which results in a production line. The upper space is narrow and the operation is inconvenient. At the same time, it will also increase the cost of production equipment. Two sets of devices are needed to meet the production needs.
