Embodiment 1

[0043] see Figure 1-9 As shown, the present embodiment is a production process of a fully automatic air-cooled refrigerator finned evaporator, comprising the following steps:

[0044] Step 1: The disc-shaped aluminum tube passes through the straightening machine, straightens according to the set size, and then blanks. The blanked material becomes an aluminum straight tube, and the thin aluminum sheet in the shape of a roll is stamped into a fin. ;

[0045] Step 2: The aluminum sheet is discharged into the mold of the equipment by an automatic sheet arrangement machine, and then the aluminum tube is filled with alcohol or water to expand the tube, so that the aluminum tube expands and combines with the fins;

[0046] Step 3: The straight aluminum tubes and fin blanks that have passed through the expansion tube are placed on the tube bending machine. After the tube bending machine is started, the straight aluminum tubes and fins are folded into an M-shaped finned evaporator s...

Embodiment 2

[0051] see Figure 4-9 As shown, this embodiment is a boss forming equipment, including a conveyor 101, a boss forming box 102, the boss forming box 102 is installed on one end of the top of the mounting frame 103, and the other end of the top of the mounting frame 103 is equipped with a mounting plate 104 , a forming cylinder 105 is installed on the top of the mounting plate 104 , and the conveyor 101 and the forming cylinder 105 are respectively located at both ends of the boss forming box 102 .

[0052] One side bottom of the boss forming box 102 is equipped with a feeding cylinder 106, the top of the boss forming box 102 is equipped with a positioning cylinder 107, and the top of the boss forming box 102 is installed with several guide posts 108, and several guide posts 108 They are located on both sides of the positioning cylinder 107 respectively.

[0053] The inner cavity of the boss forming box 102 is provided with a positioning seat 110, the top of the positioning se...

Abstract

The invention discloses a production process of a full-automatic air-cooled refrigerator fin evaporator, and relates to the field of evaporators, an aluminum pipe raw material pipe is made into an original pipe of an evaporation pipe through boss forming equipment, then the original pipe is bent to form the evaporation pipe, and the mode that the evaporation pipe is inserted into a liquid storage device is consistent with that of an existing split type. The inner inserting pipe does not need to be extruded and fixed after being inserted, the positioning boss is used for positioning, a pipe opening of the liquid storage device is round and free of deformation, automatic arc welding is better facilitated, the positioning boss is attached to the end face of the liquid storage device, the inserting depth of the inner inserting pipe is guaranteed, a welding gap is reduced, the welding leakage rate of products is reduced, and the production efficiency is improved. Compared with the prior art, welding points are reduced on the whole, the hidden danger of leakage is reduced, due to the fact that the positioning boss and the elbow are of an integrated structure, the consistency of the direction of the elbow is guaranteed, the phenomenon that the elbow is inserted into the liquid storage device without the elbow can be avoided, and due to the fact that accessories are reduced, the machining cost is correspondingly reduced.

Description

technical field [0001] The invention relates to the field of evaporators, in particular to a production process of a fully automatic air-cooled refrigerator fin evaporator. Background technique [0002] The evaporator is a very important part of the four major components of refrigeration. The low-temperature condensed liquid passes through the evaporator, exchanges heat with the outside air, vaporizes and absorbs heat, and achieves the effect of refrigeration; [0003] Air-cooled refrigerators use forced circulation of cold air to control the temperature in the box, and usually use finned evaporators to cool down. At the same time, it is necessary to set up a fan to force the air to flow, and adjust the air volume according to the different needs of the freezer and refrigerator; [0004] Such as figure 1 As shown, the existing finned evaporator liquid receiver insert tube adopts a three-stage structure, the evaporation tube and the inserted aluminum liner are split structu...
