Description

Technical Field

[0001] This utility model relates to the field of cooling technology, specifically to a spiral cooling water channel structure for hydraulic press rollers. Background Technology

[0002] The hydraulic press roller is a core cylindrical component in a hydraulic press used to transmit pressure and achieve plastic deformation or precision machining of materials. It typically works in single, paired, or multiple sets, serving as a key actuator connecting hydraulic power to the workpiece. Its design directly affects the machining accuracy, efficiency, and applicability of the hydraulic press, and it is widely used in metal forming, rubber and plastic processing, and non-metallic material handling.

[0003] Currently, as the operating time of the hydraulic press rollers increases, their temperature will gradually rise. If this temperature exceeds a reasonable range, it will cause the following problems: 1. Decreased processing accuracy: Thermal expansion of the rollers can cause changes in diameter and length (e.g., a φ500mm roller can expand by 0.5-1mm when heated by 100℃), which can damage the fit clearance with the material (e.g., the roller gap accuracy of calendering rollers), resulting in uneven product thickness and out-of-tolerance dimensions.

[0004] 2. Shortened roller life: High temperature will reduce the hardness of the roller material (such as the hardness of quenched steel begins to decrease above 200℃), which will aggravate surface wear; at the same time, repeated hot and cold cycles may generate thermal stress, which will cause the roller to crack or the chromium plating to peel off.

[0005] 3. Deterioration in the quality of processed materials: 3.1 For rubber and plastic materials: High temperature may cause excessive cross-linking, aging or surface scorching of the material (such as bubbles that may be generated when the temperature is too high during film calendering). 3.2 For metallic materials: High temperature may cause surface oxidation (such as secondary oxidation of hot-rolled steel plates) or change the metallographic structure of the material (affecting mechanical properties).

[0006] Based on the above, a spiral cooling water channel structure for hydraulic press rollers is invented. Utility Model Content
