Abstract

The invention relates to a device for detecting density of powder alloy pressed blank products, and in particular provides a device for detecting the density of aluminum-nickel-cobalt permanent magnet alloy pressed blanks. The device comprises at least two drum bodies, wherein drum covers are arranged above the drum bodies; clamping strips are arranged above the drum covers and are provided with locking bolts; a sample stage is arranged in each drum body; the drum bodies are communicated through a bottom communicating pipe; the communicating pipe is provided with a communicating valve; and a vacuum stop valve and a deflation valve are arranged above the drum bodies respectively. Compared with the prior art, the device has the characteristics of reasonable design, simple structure, accurate testing process, easy operation, low implementation cost, and the like.

Description

technical field [0001] The invention relates to a density detection device for a powder metallurgy pressed blank product, and specifically provides a density detection device for an AlNiCo permanent magnet alloy pressed blank. Background technique [0002] One of the key processes in powder metallurgy production is compression molding. The quality of the forming blank directly affects the size and performance of the final product, while the quality of the forming blank includes the unit weight, size, appearance, and the uniformity of the blank density and blank density. The single weight, size and appearance of the blank are of great importance to the final product. The density and density uniformity also play a vital role in the final quality of the product. For example, if the pressing density is too small during the pressing process, the The product is easy to cause missing edges and corners in the process of pressing and transferring, and the density of the sintered body...
