What are the technical requirements for high-quality machine tool protective cover equipment? 1. The structure and layout of the machine tool protective cover should be designed reasonably, so that the human body cannot directly enter the danger zone.
2. In order to have sufficient strength and rigidity, metal materials should generally be used, and other materials can also be usedunder the condition of satisfying strength and rigidity.
3. The protective cover of the machine tool should adopt a closedstructure. When the site needs to use the network structure, the safety distance and the opening width of the grid should meet the following requirements: in order to prevent the damage caused by fingertips, the opening width: the diameter and length of the short axis or the elliptical hole should be less than 6.5mm, and the safety distance should be not less than 35 mm. In order to prevent fingers from being damaged, the width of the opening: the diameter and length of the minor axis or the oval hole should be 12.5mm, and the safety distance should be not less than 92 mm.. In order to prevent the damage caused by the error of the palm (excluding the first metacarpophalangeal joint), the opening width of the machine tool cover: the diameter and length of the short
axis or the elliptical hole should be less than 20mm, and the safety distance should be not less than 135 mm.. In order to prevent damage errors, the width of the opening: the diameter and length of the short axis or the oval hole should be less than 47mm, and the safety distance should be not less than 460 mm. To prevent errors caused by toe damage, the gap between the machine tool protective cover and the ground (or at the station under the table) should be less than 76mm, and the safety distance should be not less than 150 mm..
4. Under normal circumstances, a fixed protective cover should be used, and the adjustment and maintenance of moving parts should be given priority. If conditions do not allow, the cover should be opened or adjustable.
5. The surface of the machine tool protective cover should be free of burrs, sharp edges and smooth, and should not become a new hazard source.
