Tyre Tread Building Machine
I. Equipment Definition and Functions
Definition : Critical equipment used in tire manufacturing/retreading for shaping, tread fitting and pressure vulcanization, to achieve physical bonding and shape curing between the structural layers of the tire.
Core feature :
Pressure forming : Hydraulic system applies pressure (adjustable from 5 to 30MPa) to precisely control the fit between the layers of the body
Thermal vulcanization : Integrated electric heating plate (up to 200 ° C ±2 ° C) to activate rubber crosslinking reaction
Intelligent shaping : Laser profile scanner real-time comparison of embryo to MOLD matching degree (error ≤0.5mm)
II. Analysis of System Composition
1.Power module
Four-column hydraulic unit (servo motor + variable pump)
Accumulator pressure compensation system (response time < 0.5 seconds)
2.Temperature control module
Zonal temperature control design (independent temperature zones for upper and lower templates)
Thermocouple closed-loop feedback (8-channel temperature monitoring)
3.Safety protection
Infrared grating interlocking (EN ISO 14119 certification)
Overpressure automatic load relief valve (threshold set at 110% of the maximum pressure)
III. Standardized operation procedures
Pre-treatment
① Clean the mold and preheat to 80 ° C (spray anti-sticking agent)
② Embryo positioning accuracy calibration (concentricity error < 1mm)
Pressure vulcanization
① Three-stage pressurization (0→10MPa→20MPa→ set value, holding pressure for 30 seconds in each stage)
② Temperature ramp control (3℃/min to vulcanization temperature)
Post-treatment
① Stepwise pressure reduction (to prevent carcass deformation)
② The automatic ejection mechanism separates the tire from the mold
IV. Industry Application Scenarios
New ENERGY VEHICLE tire manufacturing :
Low rolling resistance tread composite lamination (co-vulcanization of polyurethane and silicone materials)
Aircraft tire retreading :
High-pressure repair of aramid cord fabric layers (interlayer pressure ≥35MPa)
Special equipment field :
All-rubber track vulcanization molding (continuous pressure conveyor belt technology)
