Uniform distributing device capable of precisely adjusting powder thickness

Abstract

The invention relates to a uniform distributing device capable of precisely adjusting powder thickness. The uniform distributing device capable of precisely adjusting powder thickness comprises a handle, a scraping plate, an upper clamping plate, a left end plate, a spring, a lower clamping plate, a right end plate, a sliding block, a scraper, a rear cover plate, an adjusting bolt and a locking bolt. The handle is fixedly connected to the top of the upper clamping plate, the upper clamping plate and the lower clamping plate are fixedly connected between the rear cover plate and the scraping plate in a manner of inclining alpha degree relative to the bottom side of the scraping plate, the left end plate and the right end plate are fixedly connected to the left ends and the right ends of theupper clamping and the lower clamping, the sliding block is arranged between the upper clamping plate and the lower clamping plate, the spring is arranged between the left end plate and the sliding block, the adjusting bolt is arranged on the right end plate, the tail of the bolt abuts against the right face of the sliding block, the scraping knife is fixedly connected to the front face of the sliding block, the adjusting bolt is rotated to drive the scraping knife to lift, and the distance between the bottom side of the scraping plate and the bottom side of the scraping knife can be precisely adjusted. The device is reasonable in design, compact in structure, simple and practical. Powder is uniformly laid on a base plate with the precise thickness, and it is ensured that the experiment obtains the accurate data.

Description

technical field [0001] The invention relates to a material distributing device for metal powder cold and hot rolling slabs and composite slab experiments, in particular to a uniform material distribution device which can precisely adjust the powder thickness. Background technique [0002] The metal powder rolling process uses metal or alloy powder as the raw material, which is evenly arranged on the substrate, manually or automatically fed into the rolling mill, and directly rolled into a very thin green slab or composite slab green body, and then the green body is sintered, The second rolling and heat treatment can finally produce a porous or dense metal plate or composite plate. [0003] In 2014, "Metal powder rolling strip process technology research" was listed as a major scientific and technological project of Ansteel Group Corporation. The research and development of metal powder rolling and sintering densification technology and the construction of a complete set of p...

AI Technical Summary

Problems solved by technology

In the experimental process of metal powder rolling strip process technology research, uniform distribution of material is one of the difficulties in the experiment. Since there is no special material distribution device, a certain amount of metal powder can only be poured on the substrate, and the powder is spread manually with a thin steel plate. Sending to the powder rolling mill for rolling, due to uneven powder spreading, the surface of the rolled green body is extremely uneven, the density is uneven, and even breakage occurs, which makes the experimental data unable to be collected
