The work is set on the table and the vertical slide of the tooth head is swivelled to the required angle either towards the left or towards right from the vertical position. If otherwise, the tool will be weakened and subjected to under strain. The reciprocating motion of the mechanism inside the shaping machine can be seen in the diagram. A regulating valve admits oil under pressure to each end on the piston alternately, at the same time allowing oil from the opposite end of the piston to return to the reservoir. Save my name and email in this browser for the next time I comment. Making slots, grooves and keyways. Since oil is a liquid it has the tendency to 'leak' through every gas/slot it finds during movement. In the Shaper machine a single point cutting tool is rigidly mounted on the tool holder, which is mounted on the ram. Shaper Machine - Types, Parts, Working, Operations, Diagram While cutting gear a forming tool is used. Another precaution to be taken in tool set is that its cutting edge should not be projected much below the tool holder. The cutting tool removes the metal from work which is carefully bolted down. Now oil is entering through port A of Double-acting cylinder and position will move from left to right. If the contour (workpiece shape) has too many ups and downs both the feeds are operated by hand. Thank you For Visiting. The figure shows the machining of a concave surface using a round nose tool. 2. Introduction to Seals : Using our collaborative UML diagram software, build your own state machine diagram with a … UML State Machine Diagrams (or sometimes referred to as state diagram, state machine or state chart) show the different states of an entity. It always plays a very crucial role in manufacturing parts, different jobs, etc. If you like this article on “Shaper Machine Operations” then share with your friends. IWF Challengers Award - 2018. Now oil is entering through port A of Double-acting cylinder and position will move from left to right. Working Of Hydraulic operated Shaper machine : Hydraulic Shaping machine Circuit Diagram. The diameter of the hole should be 0.5 to 0.8mm oversize than the width of the keyway and the depth should be about 1.5mm larger than the depth of the keyway. Saif M. is a Mechanical Engineer by profession. It is known mostly for machining internal surfaces. The admission of oil to each end of the piston, alternately, is accomplished with the help of trip dogs and pilot valve. The reversal of the ram is obtained quickly without any shock as the oil on the other end of the cylinder provides a cushioning effect. The above system is a constant pressure system. Or if you have a file open already, click File > New. Lathe Machine. With suitable tools, a shaper can very conveniently machine slots or grooves on work or cut external keyways on shafts and internal keyways on pulleys or gears. Internal keyways are cut by holding the tool on a special tool holder so that the tool post will not hit against the work at the end of the stroke. The following are the different shaper machine operations: The various shapes of surfaces ate the result of either one or a combination of more than one of the above operations. A vertical cut is made while machining the end of a workpiece, squaring up a block or cutting a shoulder. For cutting slots or keyways on shafts and internal keyways on pulleys or gears. Hi all, I picked up an Alba 1A 10" shaper yesterday. By using a hydraulic DA cylinder. The feed is about 0.25mm given at the end of each return stroke. In half reciprocating stroke the tool cuts the metal and in the second half, the tool returns to the original positions. On a shaper machine, job is fixed on the work table and the tool cuts while reciprocating over the job. The work piece is held rigidly in a vice (or clamped directly on the table). The working of shaper machine can be described as follow. The stopping point of the cutting stroke in a hydraulic shaper can vary depending upon the assistance offered to cutting by the work material. For a shallow cut the apron may be set vertical but if the curve is quite sharp, the apron in swivelled towards the right or left away from the surface to be cut.
