Instructions for installing mandrel of hydraulic mandrel tube bender

The mandrel is very important relative to the bending point when producing. If the relative bending point of the mandrel beyond a certain distance, the orality will decrease.

But if the  distance is too long ,the mandrel will reduce the thickness of tube wall.

So, after bending the sample, operator needs to determine the exact position of the mandrel, this can ensure the quality of tubes.

The mandrel should put into the piercing rod in  clockwise manners, and then use screws to fix it .Operators should  attention that the mandrel must in the same direction as the bending tubes.

The mandrel die of hydraulic mandrel tube bender  can change very fast to save many times and improve work efficiency.

There are some practical operation points: 1.Put mandrel into rod before bending to avoid  industrial scrap.  2. Strictly comply with the operation specifications of mandrel tube bender to avoid accidents.   3.

 Clean up scrap iron and other fragment in time when bending to protect tube appearance.  4. Apply lubricating oil to the mandrel in time to avoid wearing ,  increase the service life of mandrel.  5.Pay attention to the direction of mandrel when bending to avoid breaking it.

What is a mandrel bender?

Mandrel bender vs tube bender

Mandrel bender is one of the tube bender. The function of mandrel is to support the inside of the tube when bending to avoid tube be out of shape. If a tube bender with mandrel, that is the mandrel bender. One tube bender can not only be a tube bender but also a mandrel bender.

Types of mandrel benders

There are many forms of mandrel .For example, cylindrical mandrel, universal single-head mandrel, universal double-end mandrel, universal three-head mandrel and universal four-head mandrel, directional single-end mandrel and directional multi-head mandrel etc. For the tubes that has different relative bending radius or relative wall thickness and different processing requirements ,operators should choose different mandrels.

When selecting rigid mandrel, the cylindrical mandrel is more common use than claw mandrel . Because of the cylindrical mandrel has simple shape and its easy to made. When selecting flexible mandrel , the ball joint mandrel is very popular. It can adopt to various deformations , because it can bend to multiple directions, and each ball joint connected with spherical .So, we often use ball joint mandrel when bending thin-walled tubes or the tubes has small relative radius. We should think about using different number of ball joints according to different relative bending radius , different relative tube wall thickness and different bending angle . The product is not good if the ball joints is too less ; it is difficult to produce tubes and its uneasy to insert mandrel when the ball joints is too many .
