A water-cooled quenching press

Abstract

The invention relates to the technical field of presses, and aims to provide a water-cooling quenching press capable of improving the quenching quality. According to the adopted technical scheme, thewater-cooling quenching press comprises a square-shaped machine frame, a work area is formed in the opening in the middle of the machine frame, an upper sliding block and a lower sliding block are arranged in the work area, an upper die and a lower die are respectively mounted on the bottom face of the upper sliding block and the top face of the lower sliding block, and a plurality of parallel cooling water ways are evenly arranged in each of the upper die and the lower die, a water parting column is arranged in each cooling water way and comprises a column body extending in the length direction of the corresponding cooling water way and a water parting ridge arranged in the circumferential face of the corresponding column body, each water parting ridge extends in the length direction of the corresponding column body, and a plurality of turbulence holes are formed in each water parting ridge in the length direction of the corresponding water parting ridge. The water-cooling quenching press can quickly cool and quench the workpiece after hot forging pressing, the quenching efficiency is improved, and the quality of the workpiece is ensured.

Description

technical field [0001] The invention relates to the technical field of presses, in particular to a water-cooled quenching press. Background technique [0002] Presses can be widely used in processes such as cutting, punching, blanking, bending, riveting and forming. Processed into parts by applying intense pressure to a metal blank to cause the metal to plastically deform and fracture. Existing presses generally include a frame and a workbench (lower mold) arranged on the frame. An upper mold is arranged above the workbench. The upper mold is driven by a hydraulic cylinder or a motor. The workpiece to be processed is placed on the workbench. The die moves downward, applying pressure to the workpiece, thereby completing the forging. However, there are still some problems in the existing presses, which need to be improved urgently. Question 1. For some workpieces, since they have protruding deformations in the up and down directions, that is, some protrude upwards and some ...

Problems solved by technology

Question 1. For some workpieces, since they have protruding deformations in the up and down directions, that is, some protrude upwards and some protrude downwards, conventional presses are used for processing. After practice, if one Forming, its forging quality is often poor, there are cracks, structural strength reduction and other problems

However, the water exchange channel used in existing forging presses is usually a through hole. This method is too simple, and the effect of cooling and quenching is not ideal, which affects the quality of the workpiece.
