TH33922B - Pipe bender - Google Patents

Abstract

DC60 This invention provides a pipe bending tool with pull (pull bend) and compression (compression bend) functions, and all bends can be performed by a single device. The pipe bender has a pipe bending unit and a pipe twisting unit. The bending unit has been rotated to an angle. was pre-determined while pressing the processed tube against the circumferential surface. of the template bent and flexed The bending unit is a movable type that moves in the direction of longitudinal tubes that have been processed or fixed The pipe twisting unit has been rotated. The freeform is a previously defined angle with the center of the treated pipe being the axis. The pipe bender is unique in that the pipe bending unit mentioned above performs the bending function. Drawn and compression bending functions of processed pipes The invention provides a pipe bending tool with both tension (tension) and compression (compression) bending functions, and all bends can be performed by a single device. The pipe bender has a pipe bending unit and a pipe twisting unit. The bending unit has been rotated to an angle. was pre-determined while pressing the processed tube against the circumferential surface. of the bent template and do the bent arrangement The pipe bending unit is a can-machine type that takes the machine in the direction. longitudinal tubes that have been processed or fixed The pipe twisting unit has been rotated. The freeform is a pre-defined angle with the center of the treated pipe, then the axis. The bent tool is unique in that the pipe bending unit mentioned above has a bent base. Pull-type and compression-bending action of processed pipes

Claims (3)

1. A pipe bender consisting of a bend unit with at least one bent template. A clamping jig for bending by rotating this clamping jig to a previously set angle on The circumferential surface of the template is bent through the tube while the treated tube is pressed into The circumference of the template surface is bent. And the roller to bear the reaction force And is a machine that It can be machined in the longitudinal direction of the pipe that has been processed. It is a self-contained unit and consists of a tubular torsion unit that receives free movement at a fixed angle. Previously, with an axially processed half of the received pipe and able to move the resulting pipe Get it through the process and go to position according to the shape of the bend. Which the above bending tool has to function Pull-type bend and compression function of process-adjusted pipe dole. The reaction force of the pipe bend unit is placed on the same axis as the bender template and the rotating clamp jig. 2. Pipe bend tool according to claim 1, which the pipe has been through the said process It has been built by a steel pipe. Stainless steel pipe, copper pipe, titanium pipe or aluminum pipe. 3. Pipe bend tool according to claim 1, which the pipe has been through the said process Have a small outer diameter of about 25 mm or less
