Hydraulic Tube Bender Introduction Parker Hydraulic Tube Bender Model HB632 For 3/8" – 2" (10-50mm) tubing and 3/8 to 1-1/2 IPS Pipe The Parker Model HB632 Tube Bender is a hydraulically operated bender for bending annealed steel and stainless steel tubing from 3/8" O.D. through 2" O.D. It is operated by means of a separate power source producing 10,000 psi hydraulic pressure. It can be operated without bolting to a table or bench if no mandrels are required, making it an excellent unit to move about and use at the point where the tubing installation is being made. It can also be attached to...

Hydraulic Tube Bender Radius Blocks Close bend radius blocks — These blocks have a threaded pin which threads directly into both Triple-Lok and Ferulok (Seal-Lok requires an adapter) tube fitting nuts, permitting a first bend very close to the end of the tube. When using radius blocks 631057-112, 631060-128, 974330 and 974350, first install the radius block adapter plate over the king pin, and then mount the radius block upon it, as shown above. *Radius to tube centerline. **Note: Sizes 20 and 24 close bend radius blocks requires the removal of the clamp arm before installation. ***Note: Size...

Hydraulic Tube Bender Medium to Heavy Wall Tube Bending The bender is shipped completely assembled except for attaching a pump, hose, and installing selected bender dies. Step 1: Mounting Tube Bender Position bender centered across the end of bender table and bolt securely in place. The Parker bender table has pre-drilled holes for bender attachment. Step 2: Connect Pump to Bender Connect the hose assembly (part no. 910004) to the pump (3/8" NPT end) and then connect hose to the bender. Be careful not to twist the hose when tightening. Use a pipe sealant on the pipe threads. The makeup for the...

Hydraulic Tube Bender Medium to Heavy Wall Tube Bending Step 5: Select Slide and Clamp Block Grooves Select the proper groove of the slide block and clamp block for the outside diameter of tube (sizes are marked on end of each block). Lubricate the slide block to facilitate its sliding. Place the clamp block in its vise. Do not lubricate the clamp block. It’s held in place magnetically. Step 6: Rapid Positioning Both the clamp and slide block vise screws feature rapid positioning, with a quick acting cam lock mechanism. To use, pull the respective cam lock mechanism to disengage, push the screw...

Hydraulic Tube Bender Medium to Heavy Wall Tube Bending Step 9: Using the Tie Bar (when required) If the tube is over 1" O.D. (25mm or 1/2 IPS), or heavy wall, or if mandrel bending, the tie bar must be used to prevent tube slippage and the clamp arm from flexing. Step 11: Bending the Tube To bend the tube, start the pump and close the valve. CAUTION — Should it become apparent that the bend is too long for the slide block, stop the bender and loosen the slide block vise. Return the slide block to its original position. Retighten the vise screw and complete the bend. Step 10: Setting Bend Angle...

Hydraulic Tube Bender Thin Wall Tube Bending with Mandrel Equipment When to Mandrel Bend For short radii bends and thin-wall tubing, mandrel equipment is necessary to prevent wrinkling, collapsing, or kinking of the tube. The mandrel supports the tube wall on the inside and maintains a full crosssection in a smooth bend. This is important and should be included as an indispensable part of bending equipment. The rule that is generally followed to determine whether or not a mandrel is necessary is as follows: When the wall thickness of the tube to be bent is 7% or more of the tube O.D., a mandrel...

Hydraulic Tube Bender Thin Wall Tube Bending with Mandrel Equipment Step 1: Mandrel Rod Stop Assembly Installation The mandrel rod stop assembly must be rigidly mounted to the bender table in proper alignment with the bender. Zero (“0”) at the end of the mandrel rod stop assembly scale must be in line with the center of the king pin. Step 3A: Install and Adjust Mandrel The selected mandrel is screwed onto one end of the mandrel rod. The other end of the mandrel rod is screwed into the adapter and then into the universal joint tongue on the rod stop assembly. The scale provided permits accurate...

Step 5: Mark the Tube Step 6: Select Slide and Clamp Block Grooves Step 7: Rapid Positioning Step 8: Positioning the Tube Step 9: Clamp the Tube Step 11: Setting the Bend Angle Step 13: Completed Bent Tube Step 12: Bending the Tube After completion of the bend, remove the tie bar, retract the slide and clamp block vises, and by pulling the tubing to the left, slide it off of the mandrel rod assembly. Then release the system pressure by opening the valve....
