Problems solved by technology

The workpiece material after quenching is easy to be brittle. In order to reduce the brittleness of the workpiece material, the traditional way is to quench the workpiece after hot pressing, and then temper or normalize. Although the brittleness of the processed workpiece is reduced, the workpiece The hardness is also reduced, and the temperature resistance and durability are low

Abstract

The invention discloses a forging, punching and quenching integrated forming process and a device. A workpiece is placed in a forming die on a punching press, and a heating device heats and calcines the workpiece; after the heating is completed, the heating device is stopped, and a punch punches the workpiece; the heating calcining and the punching are carried out alternately till the workpiece ispunched thoroughly and formed in the forming die; a cooling device is started to cool and quench the formed workpiece, meanwhile, the punch is controlled to punch the formed workpiece, so that the heat and pressure accumulated in the workpiece are released in the quenching process; and the quenching and the punching are carried out repeatedly till the workpiece is cooled and formed. According tothe process, the increasing and the decreasing of the temperature and the acting force of the punching are combined together, and the binding force among atoms is increased through comprehensively utilizing the temperature change generated by the forging, the punching and the quenching and the punching strength; the forging, the punching and the quenching are carried out repeatedly, the pressure of the workpiece is uniform, the structure among molecules is compact, the binding force is increased, the deformation amount of the workpiece is small, and the temperature resistance, the abrasion resistance and the durability of the workpiece can be increased to the largest extent.

Description

Technical field: [0001] The invention belongs to the technical field of temperature and pressure control in workpiece processing, and in particular relates to a forging, pressing, punching and quenching integrated forming process and equipment. Background technique: [0002] Forging, quenching, and stamping are three commonly used processing methods in the field of materials and machinery manufacturing. Forging, quenching, and stamping are generally carried out separately, and each has its own shortcomings. In order to improve the processing quality of workpieces, forging presses need to continuously increase the external pressure of workpieces. In order to obtain greater external pressures, it is necessary to manufacture larger forging presses. Therefore, the greater the forging pressure, the more difficult it is to increase the pressure. The workpiece material after quenching is easy to be brittle. In order to reduce the brittleness of the workpiece material, the tradition...
