Description

A magazine-type pipe supply device for an automatic fin insertion machine for air-conditioning condensers and evaporators and its application

technical field

The invention relates to a magazine-type pipe supply device for an automatic fin insertion machine for an air-conditioning condenser and an evaporator and an application thereof, belonging to the technical field of automatic fin insertion for an air-conditioning condenser.

Background technique

The air conditioner condenser is processed and formed through the assembly of U-shaped tube and fin group insertion tube, end plate and fin group assembly, U-shaped elbow and U-shaped tube assembly, and fin group 90° bending.

The fin group is usually stacked by hundreds of corrugated aluminum foil sheets with a thickness of only 1mm. The corrugated aluminum foil sheets are punched out from aluminum foil coils through punching machine dies. U-shaped tubes are usually copper or aluminum thin-walled tubes, which are bent and formed by a U-shaped tube bending machine to a certain size. After forming, defects such as springback, wear, and bending deformation are prone to occur. After the U-shaped tube is bent by the tube bender, it is sent to the material truck by the transmission belt and transported to the fin group intubation station. It is difficult to ensure the neat arrangement of the U-shaped tube. At present, most of the air-conditioning fin groups are manually intubated, and the U-shaped tubes are in a bulk state, and a single intubation is performed at a time. The reliability and efficiency of the traditional U-shaped tube bulk material supply state and manual intubation operation are very low, and the labor intensity of workers is high, which seriously restricts the improvement of enterprise production efficiency.

In order to improve the quality of air-conditioning products, improve production efficiency and reduce production costs, an air-conditioning fin insertion machine is designed, which can replace manual and automatic U-shaped tube insertion operations. The air-conditioning fin tube insertion machine can complete the automatic tube insertion of the fin group through the automatic arrangement, supply and positioning of the U-shaped tube bulk material, and the positioning of the fin group, to meet the accuracy, efficiency, safety and reliability of the automatic tube insertion of the fin group Stability requirements, etc.

In the automatic intubation assembly process of the air-conditioning fin intubation machine, which uses bent U-shaped tube bulk materials as raw materials, the feeding and positioning methods of the U-shaped tube directly affect the accuracy and production efficiency of the automatic intubation machine. This in turn affects the quality and cost of the condenser. In order to improve the automation and production efficiency of the air-conditioning fin tube insertion machine, a U-shaped tube magazine type tube supply device was designed.

Further preferably, the tube swing mechanism further includes a wedge-shaped guide plate, and the wedge-shaped guide plate is arranged in the magazine magazine where the nozzle of the U-shaped tube is located. The advantage of this design is that the wedge-shaped guide plate is a wedge-shaped structure in the vertical direction, which is used to guide the U-shaped tube up and down when stacking in the magazine magazine, reducing the deformation and inclination of the U-shaped tube. Due to defects such as springback and bending deformation of U-shaped tubes, the distance between the two nozzles has a large tolerance. In order to initially realize the neat feeding of U-shaped tubes and ensure the tolerance requirements for the distance between the nozzles of many layers of U-shaped tubes stacked, the magazine The wedge-shaped guide plate is evenly arranged in the silo. When the two nozzles of the U-shaped tube cross the wedge-shaped guide plate, the nozzle of the U-shaped tube can be corrected and supported to prevent the deformation of the U-shaped tube during the downward movement.
