1.What role does the core component of the tile pressing machine play?
The key to the tile pressing machine lies in multiple sets of upper and lower rollers. The surface of each set of rollers is engraved with concave and convex patterns that match the final wave shape (such as sine waves, trapezoidal waves, arc waves, etc.), and the patterns of each set of rollers change gradually from the entrance to the exit.
2.What is the working process of the tile press?
Feeding stage: The metal sheet enters the tile press at a uniform speed through the feeding mechanism, and the sheet moves forward continuously under the action of traction.
Initial shaping: The sheet first contacts the first few sets of rollers, and the concave and convex structure of the rollers exerts vertical pressure on the sheet, causing the surface of the sheet to begin to produce slight bending deformation.
Gradual shaping: As the sheet enters the subsequent roller groups, the concave and convex depth of each set of rollers gradually increases, and the extrusion and bending force on the sheet also increases accordingly. Because the metal is plastic, the sheet is gradually "pressed out" with an increasingly obvious wave profile under the forced constraint of the rollers.
Final shaping: When the sheet passes through the last set of rollers, its cross-sectional shape completely fits the wave pattern of the rollers, forming a stable wave-shaped structure, and the deformation is permanently retained.
3.What determines the shape of the wave?,
Roller texture design: The concave and convex dimensions of the roller (wave height, wavelength, and wave distance) directly determine the shape and specifications of the wave (such as the common 820-type and 760-type color steel plates, which refers to the effective coverage width of the wave).
Roller pressure and gap: The pressure of the upper and lower rollers needs to match the thickness of the plate (thick plates require greater pressure), and the gap needs to be precisely adjusted (usually equal to the thickness of the plate) to ensure uniform deformation and no damage to the coating.
Plate material and thickness: Metals with good plasticity (such as low carbon steel) are easier to form; plates that are too thick need to increase the number of rollers or pressure, otherwise cracking may occur.
4.What is the function of the wave shape?
After being pressed into a wavy shape, the rigidity and load-bearing capacity of the plate are greatly improved (similar to the principle of an arch bridge), while reducing its own weight. Therefore, it is widely used in scenes such as building roofs, walls (such as color steel plates), and container side panels.
5.What influence does the roller material of the tile press have on wave forming?
The selection of roller material should be based on the plate thickness, material (carbon steel/stainless steel), coating type, and production batch:
Small batch, thin gauge, low precision: gray cast iron, 45 steel (low cost) are optional; Large batch, thick gauge, high precision: Cr12MoV alloy tool steel is preferred (both hardness and wear resistance); Coated or high surface requirements: chrome alloy roller (to ensure surface quality).
