An x-ray detection device for liquid die forging products

Abstract

The invention discloses an X-ray detection device for liquid die forging products, which comprises a belt conveyor and a casing provided with X-ray detection electronic equipment, the belt conveyor passes through the casing, and the casing The body has an inlet and an outlet, and a radiation-proof curtain is arranged at the inlet and the outlet, and also includes a rotation positioning structure and a control device, and the rotation positioning structure is installed equidistantly on the belt of the belt conveyor, so The rotary positioning structure includes a placement end face and a base for placing and positioning the piece to be detected, the placement end face is rotatably mounted on the base, and the base is fixedly mounted on the belt of the belt conveyor, The control device includes a transmission structure and a manipulator, and the transmission structure is connected to the placement end surface in transmission and drives the placement end surface to rotate. The invention further improves the detection accuracy.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for liquid die forging machines, in particular to an X-ray detection device for liquid die forging products. Background technique [0002] Liquid die forging is to pour high-temperature liquid metal directly into the mold. The heat released during solidification causes the surface temperature of the mold cavity to rise rapidly. There is a temperature difference in the direction of the mold wall and thermal stress is generated. Therefore, the mold must be uniformed before use. Preheat to reduce temperature difference and reduce thermal stress. Liquid die forging can produce high-quality products, especially for components such as hubs that require high physical properties. Liquid die forging has great advantages. These products are generally detected by X-ray detection devices , X-ray detection device is now a relatively mature detection equipment, but for parts produced by liquid die ...

Problems solved by technology

However, the cost of X-ray film and other equipment consumed by this method is relatively high, and the inspection speed is relatively slow. It is only suitable for detecting volumetric defects such as pores, slag inclusions, shrinkage cavities, and porosity. The structure of the cavity has low sensitivity to the inspection of fillet welds and T-joints, and it is difficult to find defects such as cracks with small gaps and lack of fusion, as well as internal layered defects of forgings, pipes, rods and other profiles
