Sheet metal stamping device with heating function

Abstract

The invention relates to a sheet metal stamping device with a heating function. The sheet metal stamping device is characterized in that a sheet metal part is mounted on a stamping supporting seat transversely, a stamping die with a stamping cavity is mounted below the sheet metal part, a stamping head is arranged above the sheet metal part, a high-temperature heating device is mounted in a die orifice of the stamping die, a heating device is mounted in the top of the stamping head, a heat insulation cavity communicated with the stamping cavity is formed in the side face and the bottom surface of the stamping die, and an ultrasonic wave crack detection head is mounted in the heat insulation cavity. The sheet metal stamping device with the heating function has the advantages that since the stamped sheet metal part is subjected to high-temperature heat treatment in the whole stamping process, stamped portions of the sheet metal part are heated fully and evenly, crack generation can be reduced effectively and stamping quality is improved; the ultrasonic wave crack detection head is used for comprehensively detecting whether deformation portions of sheet metal have cracks or not without later detection, and accordingly sheet metal parts with the cracks can be discovered in the first time, production efficiency can be improved effectively and manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to the field of stamping equipment for sheet metal. Background technique [0002] Some small stamping machines currently on the market have been widely used because of their low equipment cost and can basically meet the processing requirements. However, the current stamping process for sheet metal parts still has the following disadvantages: cracks will occur during the sheet metal stamping process, At present, although there are heating measures to reduce the occurrence of cracks, the stress-bearing parts of the sheet metal cannot be heated evenly, and there is no effective combination of the method of reducing cracks during the sheet metal stamping process and the method of timely detection of cracks in the sheet metal. Resulting in a reduction in production efficiency and an increase in manufacturing costs. Contents of the invention [0003] Aiming at the above-m...
