- 1. TYPES OF CLAMP Submitted in partial fulfillment of the requirements of the Diploma in Mechanical Engineering By: KUNDAN KUMAR MALHOTRA (PMEG19352) VIPIN KUMAR CHOUHAN (PMEG19329) DEPARTMENT OF MECHANICAL ENGINEERING K J SOMAIYA POLYTECHNIC VIDYAVIHAR MUMBAI-400 077 NOV-2021
- 2. PRINCIPLES OF CLAMPING Principles of clamping devices are used to hold the workpiece in the correct relative position in the jig or fixture. It should ensure that the workpiece is not displaced under the action of cutting forces. For efficient operation, firm clamping of the workpiece is a must
- 3. SYSTEM OF CLAMPING ❑Once workpiece is located, it is necessary to press it against locating surfaces and hold it there against the force acting upon it. ❑The tool designer refers to this action as clamping and the mechanisms used for this action are known as clamps
- 4. WIRE ROPE • Wire clamps consist of a piece of heavy wire, typically made of steel, first bent into a tight U, • Then formed into a ring shape with one end overlapping the other, and finally the ends bent outwards and cut. • A captive nut is attached to one end, and a captive screw is attached to the other end.When the screw is tightened, the overlapped ends of the wire are pushed apart, • Tightening the wire loop around the hose. For an explanation of why this design is used,
- 5. PIPE CLAMP For clamps used to hold pipes and hoses together. They are available in various diameter sizes, commonly ½”or ¾”, suited to the same diameter piping The pipe is usually threaded on both ends. One head is fixed on the pipe by spinning it onto standard pipe threads. This head includes the screw mechanism for tightening the clamp. The other, movable, head slides onto the other end of the pipe A pipe clamp is a type of clamp often employed in woodworking, piping or cabinet shops.
- 6. DEE SHACKLE A shackle is a U-shaped piece of metal secured with a screw pin bolt across the opening, or a hinged metal loop secured with a quick- release locking pin mechanism The two types of shackles we supply are D-Shackles and Bow Shackles. D-Shackles:Also known as a chain shackle, our D- Shackles range from 0.5t to 25t. D-shackles are narrow shackles shaped like a loop of chain, usually with a pin or threaded pin closure. They are used as a connecting link in all manner of rigging systems, from boats and ships to industrial crane rigging.
- 7. SPRING CLAMP • A spring clamp is a hand tool used to apply clamping pressure quickly and easily Similar in design to a clip, • the spring clamp provides a decently strong clamping pressure • useful in holding down materials for both indoors and outdoors tasks. • spring clamps in their basic form consist of two jaws held under tension by a metal spring, • The jaws clamp down on both sides of any material to keep it in place spring clamp. Sizes range from the mini-2-inch-long spring clamp to the large 9-inch- long spring clamp.
- 8. • The most common size is 6- inches in length. • A spring clamp is commonly used in woodworking and carpentry for holding awkward or delicate objects that may be too fiddly for larger clamps • The spring clamp is commonly used for both professional and domestic tasks.
- 9. ▪ A hose clamp is an accessory that attaches onto a hose fitting such as a nipple or barb. ▪ The intent of these devices is to help seal and stabilize any hose configuration. Ultimately, ▪ clamps help to stop moving fluid from escaping from around a configuration. ▪ They do this by creating equal pressure all around and preventing gaps for internal fluids to exit that might otherwise cause a dangerous leak. ▪ Sometimes hose clamps are synonymously referred to as hose clips or hose locks. ▪ they’re used in the automotive and agriculture industries. However, ▪ such as for clamping lines during home emergency plumbing repairs.
- 10. SCAFFOLDING CLAMP A scaffolding clamp is a device used at a joint between pipes on a scaffolding structure to secure those pipes in place The overall structure is likely to use numerous clamps at every joint or connecting point. the scaffolding clamp can be tightened down, usually using a nut and bolt system, to secure each component in place. Two horizontal pipes can be secured to each other using a horizontal scaffolding clamp, for example, and the design of such a clamp will differ significantly from one used at an angle.
- 11. C CLAMP • CLAMPS ARE VERSATILE TOOLS THAT SERVE TO TEMPORARILY HOLD WORK SECURELY IN PLACE. • THEY ARE USED FOR MANY APPLICATIONS INCLUDING CARPENTRY, WOODWORKING, FURNITURE MAKING, WELDING, CONSTRUCTION AND METAL WORKING. • C-CLAMPS RANGE FROM 3/4″ TO 14″. MOST HAVE A SLIDING CROSS-PIN HANDLE OR A WING NUT THAT IS USED TO TIGHTEN THE SCREW. • CLAMP STYLES INCLUDE C-CLAMPS, BAR CLAMPS, PIPE CLAMPS, DEEP- THROAT BAR CLAMP, ONE-HANDED BAR CLAMPS, SPRING CLAMP, RATCHET-ACTION BAND CLAMP, MITRE CLAMP, AND HAND SCREWS. • BAR CLAMPS HAVE ADJUSTABLE ARMS THAT ARE EASILY WIDENED OR NARROWED TO FIT THE WORKPIECE AND, THEREFORE, REQUIRES FEWER TURNS OF THE SCREW SPINDLE, COMPARED TO A C-CLAMP, TO HOLD THE PIECE TIGHTLY.
- 12. I BEAM CLAMP ▪ This temporary fixing solution, which are also known as girder clamps, ▪ is used to suspend or secure fixtures, wires, threaded rods, and other hardware. ▪ Beam clamps can attach to the top flange up to 1-1/4” thickness. ▪ There are numerous types of beam clamps such as small mouth, large mouth, purlin, center-load, c-clamp, and light duty steel. ▪ It provides a simple and portable means of attaching a hoist to a runway or lifting beam.
- 13. Pipe fitting clamp • Pipe clamps, or pipe fixings, are best defined as the support mechanism for suspended pipes, • whether that be horizontal overhead or vertical, adjacent to a surface. • They are vital in ensuring all pipes are fixed securely • while also allowing for any pipe movement or expansion that may occur. • The smallest clamp in our range is 12mm, the largest is 1200mm. • Pipe clamps are found in all manner of household, industrial and outdoor settings. • They're used as an efficient and tidy way to restrain, secure and guide tubing or conduit for a range of plumbing, heating and electrical purposes.
- 14. HAND HOLD VISE ■ A hand vise is a tool which is designed to grip things. It can either be held in the hand, ■ This means it may be used for holding workpieces that are too small or delicate to be held in metalworking or woodworking vices. as the name implies or fastened in a bench vise. ■ Use to hold small objects tight while grinding, drilling, filing, hammering, sanding, shaping, etc. ■ Jaws have vertical and horizontal V grooves for holding round objects. ■ Use a hand vise and save your fingers. ■ Hand vise has a handle attached to a set of jaws which can clamp down on various items. ■ Smallest available: 11mm (0.5″ approx.) Largest available: 45mm (2″ approx.)
- 15. U CLAMP • A U-clamp is a bolt in the shape of the letter U with screw threads on both ends. • U-bolts have primarily been used to support pipework, pipes through which fluids and gasses pass. • As such, U-clamp were measured using pipe-work engineering speak. • A U-clamp would be described by the size of pipe it was supporting. • U-clamp are also used to hold ropes together.
- 16. BENCH VISE A bench vise is a mechanical apparatus used to secure an object that is to be worked on. It features two parallel jaws as part of the design. The device is widely used in the mechanical and woodworking industries, among others. Bench vises (or workbench vice/vise) attach directly to a workbench to hold the workpiece during operations such as sawing, planing, and drilling. The smallest of hand vices only has a jaw opening of 2mm (0.1″ approx.), whereas some larger vices, such as a reversible metalworking vice, can open to 350mm (14″ approx.).
