Problems solved by technology
[0002] The metal pipe is hollow. According to the needs of use, the pipe is usually bent. Due to the hollow characteristics of the pipe, the existing pipe bending device deforms too much when bending the pipe and causes the pipe to become unstable. If the deformation of the pipe is not enough, the It will lead to rebound at the bend, and the ideal bending effect cannot be achieved
[0003] At the same time, when the bending process of the pipe is relatively complicated and the bending angle is required to be high, for example, the bending angle of the two ends of the pipe requires both front bending and then reverse bending at both ends. The existing pipe bending device needs to go through four It takes a long time to bend repeatedly to meet the angle requirements of the part

The invention provides a pipe bending mold. The pipe bending mold comprises an upper mold and a lower mold, wherein the upper mold comprises an upper mold plate, an elastic limit ejecting rod, an upper mold swing rod and an upper mold bending block; the lower mold comprises a lower mold plate, a lower mold seat and a lower mold swing arm. The invention further provides a pipe bending technology. With the adoption of the pipe bending mold and the pipe bending technology, pipes can be bent into bent pipes with small deformation efficiently.
Description
technical field [0001] The invention relates to a mold, in particular to a pipe bending mold for bending pipes and a pipe bending pressing process. Background technique [0002] The metal pipe is hollow. According to the needs of use, the pipe is usually bent. Due to the hollow characteristics of the pipe, the existing pipe bending device deforms too much when bending the pipe and causes the pipe to become unstable. If the deformation of the pipe is not enough, the It will lead to rebound at the bend, and the ideal bending effect cannot be achieved. [0003] At the same time, when the bending process of the pipe is relatively complicated and the bending angle is required to be high, for example, the bending angle of the two ends of the pipe requires both front bending and then reverse bending at both ends. The existing pipe bending device needs to go through four It takes a long time to bend repeatedly to meet the angle requirements of the parts. Contents of the invention...
