Description

Technical Field

[0001] The invention relates to the technical field of condenser tube flattening equipment, in particular to automatic flattening equipment for long connected tubes of refrigerator condensers. Background Art

[0002] With the continuous development of society, the requirements for energy consumption are getting higher and higher, and the condenser tubes in the refrigerator are also changing. The original round tubes and steel plates were in line contact, with a small contact area and poor heat dissipation effect. Now the process has been improved to flatten the round tubes so that they are in flat contact with the steel plate, increasing the contact area and improving heat dissipation efficiency.

[0003] At present, the existing technology adopts two methods: unilateral rolling (unilateral rolling means that the roller does not move, and the product moves to achieve pressing) and direct pressing with an oil hydraulic press (direct pressing up and down). These two methods are not good at guaranteeing the deformation of the condenser tube when flattening the condenser tube, so that the condenser tube cannot effectively adapt to the flattened shape of the condenser tube during flattening, which makes it more troublesome to change the model. At the same time, the product moving method is prone to deformation due to uneven force on the condenser tube during the flattening process. In addition, the two operation methods are relatively complicated to flatten the condenser tube, thereby reducing the processing efficiency of the condenser tube. Therefore, it is urgent to design an automatic flattening device for the long connected tube of the refrigerator condenser to solve the above problems. Summary of the Invention
