Also check that moveable parts are not exposed to obstacles e.g. Before the machine is operated the following steps must be taken: Check that all safety devices function and that they are not damaged. Check the machine plate for more information.

Regarding weights, see machine plate on the machine English, rev 4 7ДЁ Operating Instructions 4126 Safety Application Never use the machine for material which is outside the capacity range of the machine. Lift carefully at the same time as you check that the rolls are pressed together. Put a lifting sling around the rolls as per figure. Check that the top roll is in the locked position. Instructions for lifting be means of travelling crane: 1. When lifting it from the packing to the permanent working site an approved lifting device type travelling crane must be used. Lifting instructions This machine must be lifted by truck as long as it is packed in a crate or a wooden case. Safety instructions in connection with the installation In order to prevent tensions in the machine it should be bolted to a solid workbench or onto optional stand bolted safely to the floor. It is important that you read the safety instructions below.

Tube bending instructions chart manual#

Read the whole instruction manual and make sure that you understand the contents before the machine is taken into use. Only authorized and trained staff is allowed to use the machine. In order to get the required bending diameter, the bending roll should by adjusted by means of the handwheel of the right hand side of the machine English, rev 4 5Д§ Safety General This machine is designed with a view to eliminating personal injuries provided that the instructions in this manual are being followed. Adjustment of rolls Introduce the workpiece between the upper and lower rolls and fasten it by raising the lower roll by means of the handwheel on the left hand side of the machine. When bending steel sheet or stainless steel the maximum thickness capacity of the machine will be reduced to about 2/3 compared to mild carbon steel sheet. Bending At the maximum operating length and the maximum sheet thickness tubes down to about 1,5 times the diameter of the upper roll can be formed and for thinner sheets down to about 1,2 times the diameter of the roll.

The bending is carried out in one operation. The prebent workpiece is introduced from the front and clamped between the upper and lower rolls. By raising the bending roll the workpiece is bent to the required diameter. 3 The workpiece is introduced from the back of the machine and clamped between the upper and lower rolls. As the rolls are asymmetrically mounted the prebending is carried out as per the drawing. Differences in sizes, options and/or accessories may or may not be pictured hereДҐ Operation Prebending In order to avoid a flat part at the beginning of the workpiece, it should be prebent first.

Choose a Bend Radius that matches your Minimum Bend.

a cutout or the edge of your flange) to your bend.

Determine your minimum bend by measuring the distance from your closest feature (i.e.

It is possible to choose other bends, but tooling charges may apply. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by Protocase. Alternatively, you can design with any value, and we can adjust it for you later in the process. If you need help choosing a value, contact us at or 1-86 and we can help. Use this document to choose values that are both manufacturable and meet your needs. It is most economical to use a single bend radius throughout the design, but if necessary, you can utilize multiple radii. ( Watch More Tech Tip Videos) Bend Radii & Minimum Bend Sizes
