The processing products of pipe bending include right angle pipe U-shaped pipe combined pipe bending snake-shaped pipe coil angle steel channel steel I-beam and so on. Bent pipe products are widely used in: trains, cars, motorcycles, strollers, steel furniture, sports fitness equipment, air conditioning piping, bathroom equipment, petrochemicals, shipbuilding and aerospace, machinery manufacturing and other industries.
How to bend a 45-degree angle?
If there is no limit switch to control the view point inside the machine, you can only look at it with your eyes, press the switch to the point of view, and then let go. If the limit switch is just fine, you only need to key the switch, and the machine will come back automatically when it is folded in place.
With a fully automatic pipe bending machine, the viewpoint is set, and it can be bent to 45 degrees at a time, which is accurate and easy to operate.
The principle of manual pipe bending machine and automatic hydraulic pipe bending machine is the same, both have to fix one end of the pipe, and use the pipe bending tool to bend it to a certain point of view. Only one uses manpower and one uses electric power, because the "power" of manpower is limited. Only small pipes can be bent, and continuous bending is not possible, and the motor can have larger torque and can bend larger pipes. But the manpower is more sensitive, and the ship is good to turn around.
For example, if you want to bend a copper pipe between 1/8"~1-5/8", how effective is the craft bend and the machine's automatic bending? Because I found that sometimes the pipe bent by the operator is not smooth, especially Inside corners, simple wrinkles.
At this time, the shortcomings of the manual bending came out obviously. The tube with a large bent copper tube needs to wear a spring or sand filling, and annealed. The craftsmanship depends on experience and tolerance! There should also be enough twists and turns. The radius is especially difficult for thin walls.
If you choose to use a fully automatic hydraulic pipe bender, you can add a mandrel to control the roundness of the pipe, while manual pipe benders can only do ordinary twists and turns. The manual pipe bender makes a mold, and after calculating the margin, the pipe can be bent manually. If the square pipe is larger, the fully automatic hydraulic pipe bender can be used.
The simple manual pipe bending is usually a steel pipe under 18mm. If it is larger than 20mm, you should consider using a hydraulic CNC pipe bending machine.
