Description

Technical Field

[0001] The invention belongs to the field of pipe bending machines, in particular to a numerical control pipe bending machine for pipes. Background Art

[0002] The existing pipe bending equipment can first cut a pipe of appropriate length, and then clamp and fix one end of the cut pipe, while the other end is in a free state. The free end is driven by the machine to drive the pipe to bend. Compared with the previous pipe bending process, it is simpler, saves cleaning steps, and reduces environmental pollution. However, during the bending process, the bending radius on the inside and outside of the bent pipe is different, and the stretching degree on the inside and outside of the bent pipe is different. When the straight section of the bent pipe is very short, the free end of the bent pipe will have a serious bevel problem, resulting in lower quality of the finished product and increased production costs. When bending the pipe, the uneven fixed clamping force can easily lead to poor bending effect of the pipe. A CNC pipe bending machine for pipes is now proposed to solve the above-mentioned problems.
