There are several ways to bend metal rods without using heat. Here are some methods you can try:
Using a pipe bender: A pipe bender is a specialized tool that is designed to bend metal rods and pipes without using heat. It works by clamping the rod or pipe in place and then using leverage to bend it to the desired angle.
Using a vise: A vise is another tool that can be used to bend metal rods. Simply clamp the rod in the vise and use a pipe or other object as a lever to bend it to the desired angle.
Using a bending jig: A bending jig is a device that is used to hold the metal rod in place while it is being bent. You can make your own bending jig using wood or metal and use it to bend the rod to the desired angle.
Using a hammer: For small bends, you can use a hammer to bend the metal rod. Place the rod on a hard surface and use the hammer to tap it into the desired angle.
Using a manual hydraulic press: A manual hydraulic press is a tool that can be used to bend metal rods without using heat. Simply place the rod in the press and use the lever to apply pressure and bend the rod.
Remember to always wear appropriate safety equipment, such as gloves and eye protection, when working with metal rods.
