Manual corrugated pipe bending machine

Abstract

The invention provides a manual corrugated pipe bending machine, and belongs to the technical field of corrugated pipe processing equipment. The manual corrugated pipe bending machine comprises a working table, wherein a wheel die, a clamp die and a guide die are arranged on the working table; the wheel die rotates on the working table; the clamp die is matched with the wheel die to clamp a corrugated pipe and rotates with the wheel die; and the guide die is arranged on the side in the reverse direction of bending rotation of the wheel die and propped against the corrugated pipe, and when thewheel die rotates and bends, the guide die tends to move linearly in the bending rotation direction of the corrugated pipe. By means of structures such as the wheel die, the clamp die and the guide die, deforming breakage and shriveling of the corrugated pipe due to stress concentration are avoided, and production efficiency and product quality of small batches of corrugated pipes are improved.

Description

technical field [0001] The invention relates to the technical field of bellows processing equipment, in particular to a manual bellows bending machine. Background technique [0002] Bending machine is a machine that can bend thin plates. It is an important equipment for bending and forming workpieces in the sheet metal industry. Its function is to press steel plates or steel pipes into parts of various shapes according to process requirements. At present, there are also many bending machines for tubular parts. Tubular bending machines can be divided into manual bending machines, hydraulic bending machines and CNC bending machines. Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. bender. The corrugated pipe is a tubular member connected by foldable corrugated sheets along the folding and telescopic direction. In order to facilitate its later installation and connection in the equipment, the corrugated pipe need...

AI Technical Summary

Problems solved by technology

[0003] Metal bellows are generally thin-walled pipes (such as Figure 5 As shown), it has a lighter weight, thus reducing the load during operation. The existing electric or numerical control steel pipe bending machine has a higher cost and is easy to damage the bellows wall on the bellows. In the process, there will be uneasy distortion and uncontrollable deformation; it will increase the processing cost and affect the production efficiency; generally, the bending of bellows is done in small batches, and it is a waste of resources to use ordinary bending machines

[0004] When bending, it is easy to cause damage to the bellows due to improper clamping; moreover, regardless of the structure and material of the bellows, the elasticity is certain, and the bending caused by stress concentration will cause the bellows to deform and break. deflated
