Reasonable arrangement of full thin oil lubrication cooling system for high-speed punch
The cooling or heating system is reasonably arranged at a certain position of the high-speed punch to promote the balance of the temperature field of the whole precision punch. The full thin oil lubrication cooling system of precision punch is reasonably designed and improved, and the influence of heat source on precision punch is reduced through lubricating oil cooling.
Through forced circulation lubrication and cooling of all thin oil, and double system oil cooling and heating equipment, ensure that the temperature of lubricating oil in the oil tank of the machine tool is controlled within plus or minus 0.5 degrees, timely provide effective lubrication and cooling for each moving pair of the transmission system, balance the temperature of the mechanical system structure, and reduce abnormal mechanical wear between each moving pair, At the same time, effectively control the cold and hot deformation of key parts, prevent the cold and hot deformation from affecting the accuracy of the machine tool, and ensure the continuity and constant processing accuracy of the high-speed punch. The working principle of the cooling system is as follows: during the working process of the high-speed punch, in view of the downward impact of the thermal deformation of the crankshaft and connecting rod on the upper slider, we set a cooling oil passage in the column of the high-speed punch, and then bring the heat generated by the high-speed punch to all parts through the forced oil supply of the forced lubrication system; In this way, the cooling oil flows to the base through the column pipeline, so that the column is heated and expanded, and the sliding block moves upward, which is good, and the processing error caused by the downward movement of the sliding block is eliminated; Further, through detailed calculation and experiment, the cooling system is designed with the connecting rod as the isothermal heat source. |
