A traction device that guides copper tubes through the fins of the condenser

Abstract

The invention discloses a traction rod and a traction device for guiding copper pipes to penetrate through condenser fins. The traction rod comprises a traction head and a rod body, wherein a pointy inserting portion is arranged at the front end of the traction head, a straight line-shaped retaining portion is arranged at the middle end of the traction head, a shielding portion bulged upwards from front to back, an arranging portion continuously bulged from the shielding portion to the highest position and a buffering portion transiting downwards from the rear of the arranging portion are arranged at the rear end of the traction head, and a joint portion is arranged between the retaining portion and the shielding portion. The traction device comprises a plurality of traction rods arranged in parallel, a support seat, sliding rails, driving mechanisms and guiding mechanisms, wherein the driving mechanisms drive the guiding mechanisms at the rear ends of the corresponding traction rods so as to drive the corresponding traction rods to move back and forth. While the traction rods retreat from the holes of the fins, the copper pipes are synchronously guided into the holes of the fins. According to the traction rod and the traction device, the structure is reasonable, the degree of automation is high, and the cost is low; the copper pipes can be safely, accurately and quickly inserted in the condenser fins, so that the pipe penetrating efficiency and precision are high, the product rejection rate and manpower cost are greatly reduced, and the traction rod and the traction device can be used in mass industrial production.

Description

technical field [0001] The invention belongs to the field of air-conditioning condenser processing equipment, and in particular relates to a draw bar and a draw device for guiding copper pipes through condenser fins. Background technique [0002] The air conditioner condenser includes a fin set and U-shaped copper tubes passing through the fin set, and passing copper tubes on the condenser fins is an important link in the preparation of the air conditioner. The traditional main process of threading tubes on fins is to rely on special material receivers to automatically and neatly stack them into fin layers, use high-speed punching machines to automatically punch fin holes for copper tubes to pass through on the fins, and then rely on workers to manually insert them into fin layers. The U-shaped copper tube penetrates into the fin channel formed by aligning the fin holes of multiple rows of fins. Since the fin is a sheet-like structure made of aluminum foil with a thickness ...

AI Technical Summary

Problems solved by technology

Since the fin is a sheet-like structure made of aluminum foil with a thickness of about 0.1mm, its material is very soft, and the thickness of the copper tube is also very thin. When the U-shaped copper tube passes through the stacked fins, it is very difficult. It is difficult to ensure that the copper tubes can pass through all the fins in turn, which will easily cause the fin holes and copper tubes to deform, and at the same time, it is easy to shift during the guiding process, resulting in the scrapping of the entire condenser and the consumption of materials

Moreover, it takes a long time to thread the pipe, the production efficiency is low, and it is impossible to realize mass production
