Description

Technical Field

[0001] This utility model relates to the field of tire production equipment technology, and in particular to an automatic tire forming machine. Background Technology

[0002] In the tire manufacturing industry, automatic tire forming machines are one of the core pieces of equipment for achieving efficient and standardized tire production. Their main function is to integrate the various components of a tire according to a pre-set process and complete the overall tire forming process. The forming quality of the tire's external tread pattern directly affects key performance indicators such as grip, water drainage, and driving noise. Therefore, thermoplastic treatment of the tire's external tread pattern is a crucial step in the tire forming process. This process requires a specific heating device and a forming mold to heat the tire carcass to a suitable thermoplastic temperature range. Then, the mold applies pressure to the surface of the carcass to form a tread structure that meets the design requirements. In existing automatic tire forming machines, some equipment uses a vertical hot-rolling die for thermoforming the tire's external tread pattern. This involves driving the hot-rolling die vertically up and down to contact and apply pressure to the horizontally placed tire blank surface, while simultaneously utilizing the die's heating function to achieve thermoplastic forming of the tread pattern. However, in these existing machines, the die's lifting and lowering operations often rely on simple screw drives or cylinder drives, lacking high-precision positioning and calibration mechanisms. This easily leads to deviations between the actual and preset positions of the hot-rolling die, resulting in uneven pressure distribution between the die and the tire blank surface. Excessive pressure in some areas can cause over-extrusion and deformation of the tire blank, and the anti-deviation and anti-displacement capabilities are relatively insufficient. Furthermore, the die's sealing and closing capabilities are relatively poor, resulting in insufficient uniformity of stamping force. Insufficient pressure in some areas leads to unclear and incomplete tread pattern formation, ultimately causing tire forming defects and severely affecting tire product quality. Therefore, we propose an automatic tire forming machine to solve these problems. Utility Model Content
