Pneumatically actuated NC Servo feeder machines serve as indispensable elements in the industrial landscape, especially in high-speed and traditional punching operations. While these machines bear a striking resemblance to their roller feeder counterparts, their sophisticated structures and operational requirements can pose certain complexities. Here, we aim to simplify the understanding of these essential machines and demonstrate how to seamlessly operate them.
Unveiling the Blueprint of NC Servo Feeders
The unique design of a pneumatically actuated NC servo feeder features two parallel and fixed wall plates vertically adhered to the sides of the machine’s head. Additional elements like a material support frame and an outlet support plate adorn the front and back of the frame, respectively. Slide grooves at the ends of the material support frame are placed in opposition, each containing a movable material stop wheel.
The core of the feeder’s structure is a Mitsubishi servo motor, cleverly nestled between the fixed wall plates. The motor’s output shaft extends through one of the wall plates, syncing up with a large synchronous pulley.
An intriguing part of the design is the inclusion of a lower roller that is rotationally linked to the fixed wall plates via bearings. Additional fixtures, such as a small synchronous pulley and a drive gear, are affixed to the roller’s sides, effectively meshing with the larger synchronous pulley.
Cap Installation Slots and Their Role
Situated above the lower roller and ensconced within the fixed wall plates, we find two opposing cap installation slots. Caps slide into these slots and exhibit vertical mobility within two arc-shaped limit slots. The ends of an upper roller connect rotationally to the caps through bearings, forming a feed path between the upper and lower rollers. The upper roller’s end is linked to a second upper gear, engaging with the drive gear.
Further enriching the design are pneumatic cylinder supports, vertically fastened to the top surfaces of the fixed wall plates. The cylinder attaches to these supports while its piston rod is vertically positioned, connecting to the cap’s exterior wall.
The Importance of Movable Wall Plates and Sealing Plates
The back end of each fixed wall plate accommodates a movable wall plate. These plates, set in opposition and parallel to each other, enclose the feeder with a sealing plate, securing the machinery’s integrity.
The Material Feeding Process: A Step-by-step Guide
The feeding process begins with adjusting the distance between the two material stop wheels to align with the material’s width. The material is then channeled through the inlet support plate and sealing plate, before entering the feed path between the lower and upper rollers.
The NC servo feeder’s cap pressure is then fine-tuned according to the material’s thickness. This adjustment allows for the material to be securely clamped between the upper and lower rollers.
Following the initial setup, the control box’s manual function performs an inching test. During this phase, the servo motor, powered by the large synchronous pulley, stimulates the lower roller to rotate the upper roller, propelling the material forward.
With a firm understanding of the pneumatically actuated NC servo feeder’s unique structure and operation, operators can unlock the machine’s full potential, resulting in greater efficiency and precision in their stamping and pressing operations. This knowledge serves as a vital tool for those working with these complex yet indispensable machines.
