Hydrodyamics Machine Tools

Hydrodynamics machine tools are a leading manufacturer & have the highest level of technology, engineering & practical knowledge and experience in tube bending tooling’s with high quality, competitive price & on time delivery. This crew, in partnership with tools for bending, can provide its customers the strongest competitive advantage, through leading edge production rates, lower unit cost, and superior bend quality. Tight radius and thin wall bends that were previously considered impossible can now be produced economically. You get high quality, on time delivery and competitive pricing. We can work with you in the design stages. We address cosmetic concerns and eliminate “Production surprises” and we can accurately determine production times and costs.

High Quality:

We work with all forms of structural steel such as Round, Rectangular, Square, Elliptical and Bars.

Tooling:

Bending Die:

Bending application required precision Bending Die have a ground tube groove, counter bores, bores and all other dimension.

The bend die helps to prevent the tube flattening & forms a given radius of bend. The bend grooves should be dead round. Bending Die is also in split construction when bend angle is more than 1800 to remove bend tube & load material. Hydrodynamics Machine Tools manufactures bending die with controlled groove of high quality.

Clamp Die:

Clamp die holds the tube in position while bending. Proper selection of material & heat treatment ensures long life clamping. Clamp length can be determined from part drawing & accordingly correct clamp can be suggested.

Clamp Type:

Diamond Knurling Clamp

Threading Clamp

Saw red blade serration clamp by Hydrodynamics Machine Tools for clamp

Radius Clamp (for 1st and 2nd bends tangents is similar)

Compound radius clamp

Pressure Die:

The purpose of the pressure die is to keep the tube against the bend die throughout the duration of bending. The Pressure die also keeps the mandrel in linear position & maintains a straight tube between tangent points of bend.

Spring back can be affected by locating & pressure of pressure die. Pressure die is adjusted for a light pressure against the bend tube. Hydrodynamics Machine Tools manufactures high quality pressure die to ensure dent free bending.

Wiper Die:

Hydrodynamics Machine Tools Manufactured wiper dies, are precision cut from pre-formed blanks of alloys steel & aluminum bronze depending on radius to O.D. Ratio and material to be bend correct wiper die can be suggested.

In many instances draw bends are required in material that is too hard, too thin or to shaped in such a manner that the metal on the inside radius of the bend forms a humps or series of wrinkles. The function of a wiper die is to fill the gap behind the bending form and confine the metal into a smooth, wrinkle free compression on the inside radius. Wiper Die should be 90% contact with bending die for longer life.

Ball Mandrel:

Hydrodynamics Machine Tools manufactures wide range of Ball Mandrels. Ball Mandrels provides maximum wall support to outside wall of tube to avoid a tube flattening while bending. Ball Mandrel flexes in any plane accommodating compound bend & eliminating setup time for plane alignment. Ball & link design provides maximum tensile strength to resist stretching or breakage. Ball is free to rotate, distribute wear and give maximum tools life. Ball and links can be added or remove easily and are available in ready stocks for field service.

Mandrel Type:

Formed Mandrel

Plug Mandrel

Uniflex Ball Mandrel

Standard uniflex ball mandrel
Close pitch uniflex ball mandrel
Ultra close pitch uniflex ball mandrel

All above mandrel can be manufactured for round, square and elliptical & even as per customer requirements. Mandrel for rotary draw bends virtually any other ferrous & non-ferrous metals including.
