Design and Fabrication of Automated Punching Machine


Abstract: In this project we are fabricating Auto roll punching machine. This project is specially designed for automatic punching in work piece. This project is to introduce automation in industries. The major components involved in this project are dc motor, CAM arrangement, conveyor arrangement and punching tool.In this project we are using two rollers, for winding and unwinding the sheet during operation. A DC motor is connected with the winding roller. A chain driver is used to transmit the power from the motor to the punching tool. The sprocket connected with the punching tool has CAM arrangement. The CAM arrangement is to convert the rotary motion of the chain drive to linear motion. The CAM provides the linear movement to the punching tool, the punching tool moves through the guide provided. After placing the work piece in the roller, the motor will be switched ON. As the motor rotates the winding roller connected to it also rotates, providing the required movement for the work piece. The CAM also starts working and the punching operation will be done automatically with equal intervals.A press or a machine press is a tool used to work metal (SOAP) by changing its shape and internal structure. A forge press reforms the work piece into a three dimensional object—not only changing its visibleshape but also the internal structure of the material. A stronger part results from this process than if the object was machined.A punch press is a type of machine press used to cut holes in material. It can be small and manually operated and hold one simple die set, or be very large, CNC operated, with a multi-station turret and hold a much larger and complex die set.Most punch presses are large machines with either a 'C' type frame, or a 'portal' (bridge) type frame. The Ctype has the hydraulic ram atthe top foremost part, whereas the portal frame is much akin to a complete circle with the ram beingcentered within the frame to stop frame deflection or distortion.U type presses have a bed plate which is used to lock the die bottom bolster. For locking the die, T bolts are used and so this plate contains 'T -slots into which t-bolts are slid in. These slots are placed diagonally and with a slot horizontal to the longer side of the plate, is the general practice. These slots run up to a central hole made in the plate, the hole being large enough to accommodate another bush with a hole, the hole being used for dropping the punched part to the bottom of the press. The top of the tool butted against a vertical sliding ram with a clamping system which accommodates only a particular diameter of a threaded cylindrical member called the "shank" of the tool. The bottom portion of the tool is locked to the bottom bed plate and the top portion of the tool is locked to the sliding ram. Top and bottom portions of the tool are generally guided by suitable pillar and bush assemblies, (one or two pairs), which givessafety to the punching elements of the tool
