Machine tool shield principle and design calculation formula

The machine guard is used to protect the machine. He protects the surface of the machine from corrosion and damage from the outside world. He has many kinds. There are: organ shields, steel shields, these two are used on the rails. Also, the screw guard used on the screw includes: round, square, and polygonal. These practices are different. Useful for wire support and stitching. There are also roller blinds and armor shields.

1. Classification and working principle of steel rail guards

The protective cover is divided into a horizontal protective cover and a vertical protective cover according to the direction of protection. Steel rail guards are generally made of 1Cr13 to prevent rust. The protective cover has a plurality of steel plates stacked together, and each side has a vertical plate on the rear side. The vertical plate is provided with a slider or a roller, which can slide on the guide rail, and the protective cover can be extended or compressed.

2. Calculation formula in the design of the protective cover

1) Shield width calculation formula

H1>(5+d)n+15; Bc>2(3+d)n+Bg+20

H1: width of the upper part of the protective cover; n: estimated number of sections; Bk: width of the side of the protective cover; Bk>(Bc-Bs)/2; Bc: protective width: d: thickness of the main body material; Bg: width of the machine guide rail.

2) Calculation formula for the length of the shield

Le=(x-15)(n-1)+x+Lg; Lz=(n-1)15+x+LrLe: amount of stretching; Lz: minimum compression; Lg: length of auxiliary rail: x: each section Shield length.
