A kind of heat exchanger cooling structure forming method

Abstract

The invention provides a method for forming and manufacturing a cooling structure of a heat exchanger, which includes a pressing auxiliary mechanism, an intermittent indexing mechanism and a displacement mechanism. The displacement mechanism is installed on the left end surface of the intermittent indexing mechanism. The pressure auxiliary mechanism is installed on the displacement mechanism, and the pressure auxiliary mechanism is located directly above the intermittent indexing mechanism; the present invention solves the problem that the existing copper tube is bent into a spiral shape by manually turning and forming on a cylinder, However, this method has high requirements on the staff, and the force is uneven during the rotation process, which easily crushes the copper tube, resulting in deformation of the copper tube. Large-scale production operations, and certain pressure-holding operations cannot be performed on the bent and formed coils, resulting in the occurrence of bending and springback.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a method for forming and manufacturing a cooling structure of a heat exchanger. Background technique [0002] Copper tube, also known as copper tube, is a kind of non-ferrous metal tube. It is a pressed and drawn seamless tube. The copper tube has good corrosion resistance and is easy to bend. The copper tube is light in weight and has good thermal conductivity. , high low temperature strength, is commonly used in heat exchangers for refrigeration or heat conduction workpiece; [0003] Copper tubes are in the state of long round tubes after they are produced in the factory format. The long copper tubes must be bent before they can be used in the refrigeration or heat conduction system of the heat exchanger. The existing copper tubes are bent into spiral shapes. The method is to manually rotate and form the cylinder, but this method has high requirements for the staff, an...

Problems solved by technology

[0003] Copper tubes are in the state of long round tubes after they are produced in the factory format. The long copper tubes must be bent before they can be used in the refrigeration or heat conduction system of the heat exchanger. The existing copper tubes are bent into spiral shapes. The method is to manually rotate and form the cylinder, but this method has high requirements for the staff, and the force is uneven during the rotation process, which is easy to crush the copper tube, resulting in deformation of the copper tube. The screw pitches are also different, which cannot meet the requirements of use, cannot be mass-produced, and cannot perform a certain pressure-holding operation on the bent and formed coils, resulting in the occurrence of bending and springback. Therefore, the present invention provides a A kind of heat exchanger cooling structure molding manufacturing method
