Device for improving temperature control precision of hot die forging press

Abstract

A device for improving temperature control precision of a hot die forging press comprises a worktable temperature control device and a sliding block temperature control device, wherein the worktable temperature control device includes a first temperature control channel arranged at the bottom part of a worktable and on the contact surface of a device body, the first temperature control channel isprovided with an air inlet and an air outlet, the air inlet of the first temperature control channel is connected with a cool-air system through a pipeline, and a temperature sensor is arranged in each of temperature measuring holes in the worktable; the sliding block temperature control device includes a second temperature channel arranged in a sliding block and on the contact surfaces of slidingblock guide plates at the front part and the rear part of the sliding block, and the second temperature control channel is provided with an air inlet and an air outlet. The temperature of the slidingblock and the temperature of the worktable are each controlled to be at a stable level, and deformation caused by temperature rise due to heating cannot be generated; meanwhile, continued conductionof the heat of a high temperature forged part is blocked, so that the phenomenon that the precision of other moving parts is changed due to heat conduction is avoided, and the overall precision, the production efficiency and the processed product quality of the hot die forging press are improved.

Description

Technical field: [0001] The invention relates to a device for improving temperature control accuracy of a hot die forging press. Background technique: [0002] With the rapid development of major engineering projects in my country's key industries such as automobiles, high-speed rail, military industry, machinery, and home appliances, the current forging industry market is increasing with the improvement of forging materials and mold quality, and the demand and output of precision forging parts are increasing. The unprecedented development opportunities for forging machinery and equipment have come, and at the same time, the precision requirements for forging machinery presses are also getting higher and higher. [0003] Because the forgeability and plasticity of metals under high temperature conditions are better than those under low temperature conditions, the current forging market mainly uses hot die forging presses and automatic production lines, such as Figure 1-2 As s...
