What is the use of clapper box in the shaper?

A hinged device that permits a reciprocating cutting tool (as in a planer or shaper) to clear the work on the return stroke. Clapper Box: The clapper box is needed because the cutter drags over the work on the return stroke.

Where is the clapper box located on shaper?

A hinged part on the tool head of a reciprocating machine (as a planer or shaper) that permits the tool to clear the work piece on the return stroke.

What are the parts of shaper machine?

Base: It is the main body of the machine.
Ram: It is the main part of the shaper machine.
Tool head: It is situated at the front of the ram.
Table: It is the metal body attached over the frame.
Clapper box: It carries the tool holder.

How many types of shapers are there?

Various types of shaping machines are classified into four such as motion type (driving mechanism), ram travel, table design, and the type of cutting stroke: Types of shaper machine base on driving mechanism: Crank type e.g. quick return motion mechanism. Geared shaper type.

What is a shaping process *?

In mechanics, shaping is a material removal process in which a cutting tool takes mass and shapes a stationary object to produce a sculpted or plane surface. Gear shaper, the shaping process used specifically for gear manufacturing.

Why quick return mechanism is used in shaper?

Quick return is a common feature of tools in which the action is performed in only one direction of the stroke, such as shapers and powered saws, because it allows less time to be spent on returning the tool to its initial position. …

Is rake a part of shaper machine?

Ram: It is the reciprocating member and carries the shaper head in its front, on which the cutting tool is mounted. It slides on the accurately machined guideways made on the top of the column. It gets its drive from the quick return mechanism which makes it run faster while returning and slower while cutting.

What are the general operation of the shaper machine?

Operations Performed on Shaper Machine: Horizontal cutting. Vertical cutting. Inclined cutting. Irregular cutting.

What is the main function of a shaper?

A shaper is a type of machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to machine a linear toolpath. Its cut is analogous to that of a lathe, except that it is (archetypally) linear instead of helical.

How is shaper specified?

How the size of shaper is specified? The size of a shaper is specified by the maximum length of stroke or cut it can make.

What is a tool head in a shaper machine?

A tool head holds the cutting tool and make its movement in vertical and Angular directions. A tool head consists of apron and clapper box. The Apron consists of a clapper box and it houses the clapper block through a hinge pin. The working principle of shaper machine is as follows:

How does the clapper box work?

The clapper box houses the clapper block by means of a hinge pin. The tool post is mounted on the clapper block.

What are the disadvantages of shaper machine?

Disadvantages of Shaper Machine: By nature, it is a slow machine because of its straight-line forward and returns strokes the single point cutting tool requires Several strokes to complete a work.

How the tool post is mounted on the clapper block?

The tool post is mounted on the clapper block. During forwarding cutting stroke the clapper block keeps the rigid support to the tool by fitting securely into clapper box and while returning stroke the tools slide over the work by lifting, the block out of clapper boxes shown in the above figure The maximum length of stroke ram.
