Intextile machinery, thescroll camis a part of the dobby mechanism.
The scroll cam is responsible for translating the motion of the dobby mechanism into the specific pattern desired for the fabric being woven. The scroll cam typically consists of a cylindrical or scroll-shaped cam with grooves or slots cut into its surface. As the cam rotates, it engages with other parts of the machine, such as levers or rods, to control the movement of the warp threads according to the pattern programmed.
Material Selection: The material for the scroll cam is usually chosen based on factors such as strength, durability, and wear resistance. Common materials includesteel alloysorcast iron GG25/GJL250 that can with stand the forces and repetitive movements involved in textile machine operation.
How to machining scroll cam?
Turning: If the cam is cylindrical or scroll-shaped, turning operations are used to shape the outer profile of the cam.
Milling: Milling operations are used to create grooves or slots on the surface of the cam according to the design specifications. These grooves are crucial for controlling the movement of other components in the textile machine.
Drilling and Tapping: Additional drilling and tapping operations may be required to create holes for mounting the cam onto the machine or for attaching other components.
Finishing: Once the machining operations are complete, the scroll cam may undergo finishing processes such as deburring, polishing, or coating to improve surface smoothness, reduce friction, and enhance durability.
