Problems solved by technology

Since the deformation of the working surface of the drawing die occurs during the stamping process, it is extremely inconvenient to measure by attaching strain gauges traditionally. It is necessary to grind and polish the measured parts of the die, which will cause damage to the die. At the same time, it is necessary to pass through the die Lead out the data line for data recording, so there is no good way to measure the deformation of the mold

Abstract

The invention discloses a device and method for measuring deformation of a drawing die of an automobile covering part in the working profile punching process. The device is composed of a dial indicator, a dial indicator fixing support, a magnetic base, a camera support and a camera. During measuring, the device for measuring deformation is attracted to a press workbench through the magnetic base, a measuring head of the dial indicator makes contact with a part needing to be measured, and then, punching is conducted; and the deformation of the die is measured through the dial indicator, data changes in the punching process are recorded through the camera, and the deformation of the die can be obtained through the data variation.

Description

technical field [0001] The invention relates to a measuring device and a measuring method for the amount of deformation during the stamping process of the working surface of a drawing die of an automobile cover part. Background technique [0002] Drawing is one of the most important processes in the stamping of automobile panels. The strength of the drawing die is directly related to the service life of the mold and the stamping quality of automobile panels. During the working process of the drawing die, its working surface will be deformed due to the huge pressure. This deformation not only affects the life of the die, but also has a direct impact on the forming quality of the parts. Therefore, the maximum deformation of the working surface of the drawing die Quantities need to be measured. Since the deformation of the working surface of the drawing die occurs during the stamping process, it is extremely inconvenient to measure by attaching strain gauges traditionally. It ...
