Double-bending device and bending method for air-conditioning condenser

Abstract

The invention discloses a two-time bending device and a bending method of an air conditioner condenser. The bending device can be controlled by a programmable logic controller in the centralized form, and the condenser is bent by a bending machine comprising a rack, a bending die positioning mechanism, a positioning mechanism, a bending die, a clamping support plate, a servo bending mechanism and a servo support plate; a feed clamping mechanism is installed correspondingly in parallel behind the bending die, and one end of the feed clamping mechanism is connected to a servo feeding mechanism. Upon completion of primary bending of the bending machine of the bending device, the feed clamping mechanism is used to push forward for secondary bending, so that one-way multi-bends of the condenser are achieved, with parametric control and accurate positioning. In the bending method of the bending device, the whole bending process of ''automatic positioning - bending - feeding - re-bending'' is finished through automatic circulation, the bending device has the features of high automaticity, high production rate, easy operation, stable and reliable operation, high positioning accuracy, etc., and the manpower and material cost for bending the condenser is reduced.

Description

Technical field [0001] The invention belongs to the technical field of condenser bending, and particularly relates to a double bending device and a bending method for an air conditioner condenser. Background technique [0002] At present, the cooling medium circulation system of the outdoor unit of the split air conditioner is formed by punching the aluminum foil into the shape, the copper tube is inserted into the aluminum sheet, and the flat condenser is processed through the production process of tube expansion, degreasing, welding, and leak detection. Assembling products, the flat-plate condenser assembly is bent into an outdoor unit and connected with the compressor and circulating assembly to form a refrigerant circulation system. Therefore, the condenser is an important component of the air conditioner for heat and cold exchange. [0003] The condenser bending machine is a special equipment for bending flat condensers. The existing condenser bending machines have two types, ...

AI Technical Summary

Problems solved by technology

[0003] The condenser bending machine is a special equipment for bending flat condensers. The existing condenser bending machines have two types: single bending and bidirectional multi-bending. Among them, the production process of single bending is not only low in production efficiency, but also Moreover, the positioning accuracy is low. Although two-way multi-bending can improve production efficiency, but both sides of the condenser are bent at the same time, and the internal tension of the condenser cannot be dredged at the same time. The middle part is prone to local slight disintegration, which affects product quality.
