Description

Technical Field

[0001] The invention relates to Europeanized furnace air pipe processing equipment, in particular to Europeanized furnace air pipe automatic production equipment. Background Art

[0002] European stoves are designed for outdoor activities such as camping and barbecue, which shows that they are portable and efficient in heating. For example, a European stove is specially customized for outdoor camping and barbecue, which has energy-saving and environmental protection functions and is suitable for use in outdoor environments.

[0003] Website: https: / / www.bilibili.com / video / BV1mD421u74j / The video in the video discloses a fully automatic pipe bending machine, whose pipe bending die cooperates with two clamping dies, one of which passively follows the rotation after abutting, and the other one first abuts and then actively moves in the front and rear directions. The active movement is currently achieved by a cylinder cooperating with a controller.

[0004] Since the rotation of the pipe bending die requires a power device, during its rotation, the second clamp actively follows the movement and needs to be driven by a cylinder. It is difficult to control the two systems in complete synchronization, and lags are prone to occur, resulting in deviations in the clamping position of the second clamp, which ultimately causes the bending quality to fail to meet the requirements.
