Tube bending tools

Tube bending tools sets and separate tools


We are ready to supply from separate tools according to the customer specification till the complete set of tools (bending die, clamps, guides, mandrel, wiper die, collet etc.) for the specified diameter and the radius of tube.
We have a possibility to offer the tube bending tooling from simple set for easy-bended tubes up to complicated solutions with the several levels of bending die (multi-stack), one- or multi-ball mandrels, special surfaces for short straight part and tight clamping, special profiled tooling and hydroforming shapes, tools for bending of profiles, square and rectangular tubes, roller tools for push bending etc.
Tooling is made with proper heating treatment for the best hardness of material and maximization of lifetime for tool use.


Tube bending tools

Multi-stack tube bending tools


If your tube bending machine supports the installation of tube bending tools on several levels we can offer not the one level tools but Multi-stack (Multi-level) for all necessary radiuses and shapes. Usually solid Multi-stack tools are used as the way to save some money against necessity to order separate tools. Moreover the installation of Multi-stack tools is more quick and effective if you have the repeated production. If necessary we can offer the production of standard draw bending tools as well as push bending tools.
Multi-stacked tools could be made as separate components of tools with possibility to install on different levels (with special fixation plate - more universal and convenient construction) as well as solid multi-level pieces with impossibility to change the levels. Usually solid body is necessary to use for the possibility to perform normal forces on top to prevent non-bending or breakage.
Usually the construction of Multi-stack tools and any installations of the tools on the machine on different levels are made to make as pyramid with bigger radiuses on lower levels.

Bending dies


Bending die is the main part to form the radius of bending. Front clamp tights the tube together with the clamp of bending die to prevent any movement and then bending die rotates around the center axis to "draw" the tube along the profile of the die. We supply from simple one-level bending dies till complicated multi-level (multi-stack) bending dies with different radiuses of bending.
list Solid part or bending die with clamp insert
list Standard or special surface
list One level or Multi-stack
list Compound profile for bend-in-bend
list Right or left bending
list Connected with the flange for mounting
list Interlock clamping
list Integrated shaft of bending die for solid multi-stack tools
list Special shafts to make springs and coils, flanges together with shaft and thread if necessary, any individual constructions
list Heavy pieces with eye-bolts for crane lifting


Tube bending tools

Clamps and guides


Clamps are necessary to fix the tube during the bending process. Front clamp performs the clamping together with the clamp of bending die to prevent any possible movement or sliding. Guide follows the bend as the movement of machine to prevent the inclination of the tube to control the saving of the geometry. We supply from simple one-level clamps and guides till complicated multi-level (multi-stack) tools.
list Standard or special surface (normal, microserrated, noise made by EDM or other possibilities)
list One level or Multi-stack
list Compound profile for bend-in-bend
list Right or left bending
list Short clamps with tight fixation of tube for tight clamping
list Interlock clamping
list Connection adapters
list Elongation spacers


Tube bending tools

Collets


Collets for tube bending machines are made according the diameter of tube to clamp it inside the carriage. Collet includes the body and jaws for fixation. Hole is used for passage of mandrel rod. Some machines are used universal chucks, individual clamping collets are not necessary. Clamping is usually made with the use of pneumatic or hydraulic systems. Mainly on tube bending machine also collet perform the rotation of the tube around the centerline.
list Segmented pieces or separate segments as spare parts
list Springed solid collets
list Construction equal to original collets of the machine or special designed
list Steel body
list Special geometries for non-round form of tubes
list Various quantity of jaws based on geometry and construction


Tube bending tools

Mandrels


Mandrel is the necessary part for mandrel bending to prevent the tube internal deformation and remove of wrinkes in the area of bending. We supply mandrels for any type of tube bending machines and any hardness of the construction. Our mandrels are also produced with internal connectors and balls - this construction is much more progressive than use of steel ropes for quality and life of the tooling with possibility to change the internal components if necessary.
list Solid part or ball mandrel
list Standard or small pitch between balls
list Special mandrels for square and rectangular tubes
list Lubrication supply
list Made in aluminium-bronze alloys for hard materials of tube or steel for soft materials
list Internal or external connection thread
list Special nose geometry according to planned tube deformation
list Optional coating
list Groove for welding seams
list Length according to the customer's request

Wiper dies


Wiper die is the special tool which has to be installed together with the bending die to prevent the appearance of the wrinkles and corrugations of the bended area of the tube. We supply wiper dies according to any customer's specification. (It is important that the machine has the option to hold and install wiper dies).
list Solid body or wiper die with insert
list Different materials according to the material of the tube
list Easy clamping
list Micro finishing
list Length according to the connection sizes of the machine
list Made in aluminium-bronze alloys for hard materials of tube or steel for soft materials


Tube bending tools

Push bending tools


Push bending (or thrust bending) is a special process for tube bending machine to push the tube with the controlled force through the rollers specially positioned to form the radius. Mainly this process is widely used for making of big radiuses (5 diameters of tube and bigger) and standard for application like forming in way of spring, coil, parts of furniture, for example chairs etc. Moreover push bending tools are do not required for one single diameter so if your machibe supports push bending technology you can look forward to use it for more purposes. We are offering complete solutions for tools for push bending as separate sets as well as composition with standard draw bending tooling and push bending on different levels of tube positioning. Also, interchangeable rollers could be ordered as well.
