[0002] Air conditioner copper pipe is the key pipeline for connecting various components in air conditioner refrigeration system, usually adopts red copper material. It has good thermal conductivity, can efficiently circulate and transport refrigerant between evaporator and condenser, so as to realize heat exchange.

[0003] In the drawing process link of air conditioner copper pipe, when the copper pipe is pulled through the die hole of the drawing die, the outer wall of the copper pipe and the inner wall of the drawing die will produce direct contact and relative movement. Due to the material properties of the copper pipe and the drawing die, the friction coefficient between them is large, which leads to a large friction force between them. At this time, artificial oiling is needed continuously. However, manual oiling needs the operator to manually apply lubricating oil, which not only increases the labor intensity, but also the application speed is slow, which is difficult to meet the requirements of copper pipe drawing speed and production efficiency in modern production, resulting in the reduction of the efficiency of the whole production process.

[0004] Therefore, the utility model provides a fixed length drawing equipment of air conditioner copper pipe. UTILITY MODEL CONTENTS

[0013] As a preferred implementation form, the bottom end of the oil outlet pipe is close to the stretching hole, and the bottom end of the oil feeding pipe is fixedly connected to the inside of the oil draining frame and placed in the oil taking area.

Through the cooperation of the heating and oil feeding assembly and the heating rod, the lubricating oil is automatically heated, the viscosity of the lubricating oil is reduced, the lubricating oil can flow smoothly between the copper pipe and the stretching die, thereby reducing the friction and improving the stretching efficiency. Meanwhile, during the oil circulation process, the backflow partition plate effectively controls the flow direction and amount of the lubricating oil, so that the lubricating oil can be recycled between the two areas, thereby avoiding the waste of oil. Secondly, the oil can be supplemented through automatic adjustment, so that the oil amount is always at the optimal level, thereby ensuring the continuous and stable lubrication effect, thereby effectively reducing the need for manual application and reducing the labor intensity.
