These components; Center former, pressure die, clamp die, wiper die and flexible mandrel are specific to material type and dimension.The following must be supplied when ordering mandrel tooling: Profile shape, interior and exterior dimensions, wall thickness, material type, minimum distance between bends and number of bends per day required. It is highly recommended dimensional drawings of finished product be supplied with mandrel tooling orders. All mandrel tooling is special order and requires non refundable advanced payment.When is a Mandrel Necessary?When a tube is bent, the outside wall of the tube collapses and thins out, and the inside of the tube compresses and wrinkles. The minimum tool requirements for rotary draw bending are the center former bend die around which the tube is bent, and a counterbending die to holds the tube in place as it bends. Satisfactory bends are achieved using a center former and coun-terbend die when bending pipe or tubing with a heavy wall or a large centerline radius. When bending thin wall tube use of a mandrel and wiper die are necessary. The mandrel minimizes the amount of ovality that occurs on the tube while the wiper die eliminates wrinkles on the inside radius of the tube.CoMPoNENTS of MANdREL BENdINGCenter former/Bend die: The primary tool which determines bend radius of the tube. Manufactured from tool steel or alloy steel and heat treated depending on requirements. Ercolina® bend dies are manufactured in the one-piece style.Clamp die: Matches center former clamp surface and has the same grip finish as the grip area of center former. The clamp die's primary function is to hold tube securely to the center former.Pressure die: Used to maintain constant pressure on tube at tangent where the bend occurs, providing reactionary force to make the bend. Length of the pressure die depends on the degree of bend (DOB) of part being bent and the machine design.Wiper die: Manufactured to match center former radius. Mounts into the tube groove of the center former with tip positioned near tangent point of bend. Primary function is to prevent wrinkling on the inside radius of the tube. Wiper dies are typically manufactured from AMPCO® bronze.Mandrels: Generally made from the same material as the wiper die. Primary function of the mandrel is to prevent the outside diameter of the tube from collapsing. Choosing the correct mandrel is very important in determining quality of the bend. The three basic styles of mandrels are:1. Plug mandrel used for heavier walled tube or large CLR bending.2. Standard open pitch mandrel is most widely used because it covers the widest range of bending applications. Standard mandrels are made with one to three balls. Open pitch mandrel is the most durable of the three flexible mandrel configurations because it uses the largest size links possible.3. Thin wall mandrel (close pitch mandrel) used mostly for thin wall tubing. Thin wall style mandrels use the same style linkage as standard mandrels except the size of the link is the next size smaller than it would be on a standard mandrel. For example, where a standard style mandrel would use a #10 size link, a thin wall style mandrel would use a #9 size link. The effect being that the ball segments are now closer together and provide more support needed for thin walled tube bending. Strength is sacrificed for more support.Lubrication: Comes in several different forms such as oil, grease, and paste. The kind of lubrication used will depend on the material of the tube to be bent. A generous amount of lubrication may be applied to the mandrel and the inside of the tube, however precautions should be taken to avoid getting lubrication on center former and clamp die. Proper lubrication is important to making good bends.Center FormerWiper DieFlexible Mandrel Pressure DieClamp DieMandrel Tooling Information19CML USA Inc.
