Rotary cutting method of foaming sponge

Abstract

The invention provides a rotary cutting method of foaming sponge. The method comprises the following steps: (1) cutting top convex part and bottom of the foaming sponge with thickness of the cut part being 10-30cm; (2) bonding at least two pieces of the foaming sponge with top convex part and bottom thereof cut along top and bottom interfaces which are vertical to moving direction of the foaming body; and (3) rotarily cutting the sponge into sponge pieces along the direction parallel to the upper and lower axes. The method can help cut the sponge into sponge pieces with even hole distribution and uniform hole form, dark and light interlaced stripe phenomena of the porous sponge metal made from the sponge pieces obviously disappears, fluctuation of physical property of the product is small, and all technical indexes are good.

Description

Technical field [0001] The invention relates to a peeling method of foamed sponge. Background technique [0002] In the manufacturing process of porous sponge metal, sheet sponge is used as a carrier for metal deposition. The pore uniformity and pore shape of the sponge itself directly affect the uniformity of metal deposition on its surface and affect the final product. The main physical properties. At present, the sponge slicing process is generally to cut the block sponge into a sheet of the required thickness. The rotary cutting method is: peeling along the direction parallel to the moving direction axis of the sponge ("horizontal direction"), but In the foaming process of the sponge, the pores at the bottom of the foam have a larger pore diameter than the top pores, and because it is continuously foamed, the direction of the pores is slightly inclined to the end of the foam, and the longitudinal pore structure of the sponge is quite different. Therefore, the horizontal rotat...

Problems solved by technology

At present, the slicing process of the sponge is generally to slice the massive sponge body into sheets of required thickness. The rotary cutting method is: along the direction ("horizontal direction") parallel to the moving direction axis of the sponge body. During the foaming process of the sponge, the pores at the bottom of the foam body are larger than the pores at the top, and because of continuous foaming, the direction of the pores is slightly inclined to the end of the foam body, and the structure of the longitudinal pores of the sponge is quite different. The cutting method makes the pore distribution of the flaky sponge after rotary cutting very uneven, and the shape of the holes in each part is greatly different, which leads to the phenomenon of light and dark interlacing (stripes) in the porous sponge metal made of this flaky sponge, and its physical properties Large performance fluctuations and poor index values
