Manufacturing requirements for heating system of single-sided hot press
The traditional heating method of the double-sided heat press is steam heating and electric heater. The steam heating and heating are rapid, but the working pressure heating furnace of weapons and equipment is required. The working pressure of the pipeline is high, and the steam is easily cooled and turns into water, causing uneven surface temperature.
Single-sided and double-sided stickersHot PressThe traditional heating method is steam heating and electric heater. The steam heating and heating are rapid, but the working pressure heating furnace of weapons and equipment is required. The working pressure of the pipeline is high, and the steam is easily cooled and suspected to become water, resulting in uneven surface temperature. The electric heater has the characteristics of rapid heating, high heating temperature, simple operation, etc., but it uses a large amount of electricity, high cost in work, and has defects such as defects that the electric heating wire is not easy to replace in actual application.
Therefore, when the single and double sides are pastedHot PressWhen used in the home improvement industry, when the pressing temperature is not high, the hot water circulating furnace can also achieve satisfactory actual results, and the fixed capital injection and the cost of work are very low. Single-sided and double-sided stickersHot PressThe pressed plate is generally produced and processed by a whole piece of thick steel plate of tube bundle through deep hole drilling, which can avoid oil leakage caused by poor sealing performance.
Single-sided and double-sided stickersHot PressThe bending stiffness and compressive strength of the pressed plate are high, but the pressed plate is thicker. Because the method of sheet metal is generally used, because the ground stress will be generated in electric welding and production and processing, and the machining precision is high. The thin pressure plate is convenient for heating and temperature control, but the requirements for parts processing are high, and uneven thickness of steel parts will cause pin deformation, thus endangering the quality of subsequent production and processing.
Single-sided and double-sided stickersHot PressDuring production and processing, the flatness of the pressed plate and sufficient flatness of the left and right surface layers shall be ensured. The flatness dimension tolerance of the pressed plate shall be within the range of 0.1-0.20mm, the flatness dimension tolerance shall be within the range of 0.15-027mm, and the pin roughness shall be 3.2 μm m. The temperature difference of each part in the whole width of the pressed plate shall not exceed 2-3 ℃, so as to prevent the compressive strength and appearance quality of the goods from being harmed.
Single-sided and double-sided stickersHot PressMost of the connecting pipes of the pressure plate are dominated by plastic hoses, which makes the connection very convenient. Metal bellows and Teflon hose can be used flange connection, Teflon hose against fatigue function is better than the metal bellows. Sealing gasket raw materials such as polytetrafluoroethylene, wound high-purity graphite, the actual sealing effect is stronger.
