Ram and tool head: The ram is driven back and forth in its slides by the slotted link mechanism.Sliding along the cross rail is a saddle which carries the work table. The structural behaviour under static and dynamic loads is evaluated in order to obtain an optimized design. The vertical movement of the cross rail permits jobs of different heights to be accommodated below the tool. Shaper machine produced by the Egyptian Machine Tool Factory is selected for this study. Cross rail: The cross rail is mounted on the front of the body frame and can be moved up and down.The top of the body provides guide ways for the ram and its front provides the guide ways for the cross rail. knowledge of Machine tools such as Lathe, Shaping Machine, Milling machine etc and their use in performing different operations in the manufacturing such as. Body (Pillar, Frame, Column): It is mounted on the base and houses the drive mechanism compressing the main drives, the gear box and the quick return mechanism for the ram movement.The base absorbs and withstands vibrations and other forces which are likely to be induced during the shaping operations. It supports the body frame and the entire load of the machine. Base: The base is a heavy cast iron casting which is fixed to the shop floor.The forward and return strokes constitute one operating cycle of the shaper.Ĭonstruction: The main parts of the Shaper machine is Base, Body (Pillar, Frame, Column), Cross rail, Ram and tool head (Tool Post, Tool Slide, Clamper Box Block). During return, there is no cutting action and this stroke is called the idle stroke. As the ram reciprocates, the tool cuts the material during its forward stroke. The reciprocating motion of the ram is obtained by a quick return motion mechanism. The single point cutting tool held properly in the tool post is mounted on a reciprocating ram. The job is rigidly fixed on the machine table. Producing contour of concave/convex or a combination of these. Producing a flat or plane surface which may be in a horizontal, a vertical or an angular plane.The shaper is a machine tool used primarily for:
