Dec 05, 2020· Hydraulic Shaper Mechanism. In this type of shaper machine mechanism, the ram is moved forwards and backwards by a piston moving in cylindrical placed under the ram. The machine is consists of a constant discharge oil pump, a cylinder, a valve chamber and a piston. The Piston-rod is bolted to the ram body. As shown in the figure.
CHAPTER NO:6 SHAPER MACHINE. PREPARED BY: BRAMHAKSHATRIYA GIRISH M. INTRODUCTION: A shaper is a type of machine tool that uses linear relative motion between the work-piece and a single-point cutting tool to machine a linear tool path Its cut is analogous to that of a lathe, except that it is linear instead of helical A shaper is analogous to a planer, but smaller, and with the …
SHAPERS: Horizontal Push cut, Pull cut or draw cut shapers Vertical Regular (slotters), keyseaters Special Disadvantages - cutting speed is not constant - force of cutting varies with the position of the crank Advantages - return of the tool –faster - tool hits the work at lower speed Hydraulic Shaper - Ram –driven by hydraulic cylinder
Apr 15, 2017· Gear shapers have a reversible electric motor or mechanical mechanism which quickly returns the ram, in readiness for another cut. Hydraulic shapers are driven by movement of a piston in an oil-filled cylinder. Mechanical features on these shapers are the same as those on crank shapers…
3. Hydraulic pump (compressor in pneumatics): converts the mechanical energy into hydraulic energy by forcing fluid from the reservoir into the system. 4. Fluid lines: transport the fluid to and from the pump through the hydraulic system. 5. Valves: control pressure, direction and flow rate of the hydraulic fluid. 6.
This mechanism is known as quick return mechanism. The reciprocating movement of the ram and the quick return mechanism of the machine are generally obtained by anyone of the following methods: (1) Crank and slotted link mechanism (2) Whitworth quick return mechanism, and (3) Hydraulic shaper mechanism

Mar 10, 2019· Working Principle of the Shaper Machine. In the Shaper machine a single point cutting tool is rigidly mounted on the tool holder, which is mounted on the ram. The work piece is held rigidly in a vice (or clamped directly on the table). The ram reciprocates and thus cutting tool held in tool holder moves backward and forward on the work piece.
Sep 20, 2016· Shapers are classified under following headings. 1) According to the type of mechanism used – a)Crank type b)Geared type c)Hydraulic type 2) According to the position and travel of ram- a)Horizontal type b)Vertical type 3) According to type of design of table- a)Standard shaper b)Universal shaper 5.

9. Quick return mechanism and reciprocating movement of the ram is obtained in _____ mechanism. a) crank and slotted link mechanism b) whithworth quick return mechanism c) hydraulic shaper mechanism d) all of the mentioned Answer: d Clarification: These both desired properties are obtained in all mentioned mechanisms.
Hydraulic circuit for Shaper M/c Fig shows the hydraulic circuit for operation of shaper. Here meter- out circuit is used. It consists of hydraulic power unit which delivers the oil at constant pressure. A double acting cylinder is used to reciprocate the ram A pivot actuated D.C. valve is used to alter the direction of stroke of the piston
HYDRAULIC CIRCUIT DESIGN AND ANALYSIS A Hydraulic circuit is a group of components such as pumps, actuators, and control valves so arranged that they will perform a useful task. When analyzing or designing a hydraulic circuit, the following three important considerations must be taken into account: 1. Safety of operation 2.
The hydraulic circuit for a milling machine is comparatively different from the hydraulic circuit of the surface grinding machine and hydraulic circuit of the shaper machine. This is because the table movement in milling operation is comparatively slower.
Jul 13, 2019· Abstract:- A shaper is used to machine a single job by using a single point cutting tool and hence it cannot be used for high production rate. A small Scotch yoke mechanism has been thus devised to demonstrate the dual side machining time reduction in shaping machines. This shaping machine has an idle stroke during its return motion.
Clarification: Travelling head type shaper is type of shaper according to, position and travel of the ram. In workshop, if we have a machine that cannot be fixed on the machine or can not be moved at that time we use this shaper. 7. Hydraulic type shaper is type of shaper according to_____ a) design of the table b) position and travel of the ram
SYNOPSIS. JCB machine is a type of crane, which contains horizontal member called arm, movable unit and mounted pillar. JCB machines are used in industrial application and also in constructional purposes. It may be fitted to top of the floor and is used to lift the heavy loads from …

The hydraulic circuit of the shaping machine utilizes a double-acting cylinder with a single-piston rod and spool type direction control valve, which is shifted by a reversing lever. The hydraulic power pack supplies the pressurized oil to the spool valve.
May 12, 2021· 2.2 Vertical Shaper Machine. In these types of shaper machines, the ram reciprocating in verticle plane. In this, the table holds the workpiece. Verticle shapers maybe crank driven, rack-driven, screw-driven or hydraulic power-driven. The vertical shaper is very convenient for machining internal surfaces, keyways, slots or grooves.
