After the various topic of discussion on shaping machines. We realized that shaping machine parts need to be dealt with. So far, the machine was explained to be a reciprocating machine tool ideal for producing vertical, horizontal, and inclined flat surfaces. It is suitable for generating smooth rough surfaces, gear teeth, etc.
Today we’ll be looking at the parts of a shaping machine and their various functions.
Shaping machine parts:
The following stated below represent the component of the shaping machine tool:
Just like other machine tools, the base is designed to take the entire load of the shaping machine. It is bolted on the floor of workshops. The base is made of cast iron in order to resist vibration and to take the compressive load.
The column is cast iron mounted on the base. It is provided with accurate machine guideways on the top on which the ram reciprocates. Some guideways are also provided on the front vertical face for the cross-rail movement. All ram-driving mechanism is enclosed in the column.
The shaping machine part is mounted on the ground vertical guideways of the column. It features two parallel guideways on its top perpendicular to the ram axis, this is called a saddle. It helps to move the table crosswise direction with the help of a feed screw.
A cross-rail allows the table to be raised and lowered at a required size the workpiece will accommodate. This is done by the rotating elevating screw that causes the cross rail to slide up and down on the vertical face of the column.
A saddle is mounted on the cross rail to hold the table firmly on its top. The crosswise movement of the saddle causes the table to also move crosswise direction if the cross-feed screw is rotated.
A table is mounted on the saddle, it moves crosswise by rotating the cross-feed rod and vertically by rotating the elevating screw. The table is made of cast iron, in the shape of a box with an accurate top and side surface. These surfaces feature t-slots for holding the workpiece.
In a universal shaping machine, the table is designed to swivel on a horizontal axis and its upper part is tilted up or down. In heavy shaper, the front face of the table is supported by an adjusted table to offer more rigidity.
A ram is a reciprocating member that holds a shaping tool. It is in the form of a semi-cylindrical and ribbed inside which makes it more rigid. It holds the screwed shaft for altering the position of the ram with respect to the work.
the tool head is designed to firmly hold a cutting tool and offers both vertical and angular movement to the tool. This movement is done by a down-feed screw handle. The tool head also allows the tool to have automatic relief during the return stroke of the ram.
the head tool consists of an apron, a clapper box, and a clapper block; the apron contains the clapper box and tool post, clamped on the vertical slide by the screw. The apron is swiveled upon the apron swivel pin in the direction of right or left. The clapper box houses the clapper block using a hinge pin. A tool post is mounted on the clapper block.
