Method and device for collecting fins and arranging and combining fins and flat pipes

Abstract

The invention discloses a method for collecting fins and arranging and combining the fins and flat pipes, which comprises the following steps of: (1) finishing equidistant arrangement of the flat pipes by using a pipe-arranging mold; (2) covering a large tray on the arranged flat pipes, turning, and putting the flat pipes into a fin and flat pipe collecting device assembly; (3) pushing a movable block to make the large tray support the flat pipes so as to clamp front ends of the flat pipes in a clamping groove of a guide block, and taking the pipe-arranging mold out; (4) automatically guiding the fins into a guide groove which is composed of the guide block and the flat pipes, and finishing the fin collection and arrangement of the flat pipes; and (5) loosening the movable block, collecting the arranged fins and flat pipes in a small tray or directly assembling the fins and the flat pipes, or stacking and storing the fins and the flat pipes. The invention also provides a corresponding device according to the method, which mainly comprises a pipe-arranging mold, a fin and flat pipe collecting device assembly and a small tray. The method for collecting the fins and arranging and combining the fins and the flat pipes has the advantages of no need of manually collecting the fins, reduction of a transfer program, capacity of preventing adhesion between the fins, automatically arranging the fins and the flat pipes, improving the product quality, along with low equipment investment and contribution to lean production.

Description

【Technical field】 [0001] The invention relates to the technical field of manufacturing automobile heat exchangers, specifically, a method for collecting fins and arranging and combining them with flat tubes, which can significantly improve the assembly efficiency and quality of the core body of the automobile heat exchanger, and save equipment investment. Supporting production equipment. 【Background technique】 [0002] At present, in the manufacture of automobile heat exchangers, most enterprises adopt the production method of firstly stacking a row of flat tubes with a row of fins, then combining multiple rows of flat tubes with fins, and then assembling with the liquid collection pipe. Way. In terms of fin collection and arrangement and combination with flat tubes, the widely used technology is: the fins are made by the fin machine and collected manually, put into the turnover basket, and then take the fins in turn when assembling the heat exchanger core. Align with the ...

AI Technical Summary

Problems solved by technology

[0005] (1) There are too many fin turnover processes, which affect the surface quality of the product

Because the fins themselves are very thin, it is easy to cause adhesion when they are collected together. When taking the fins, they need to be separated by force, which is easy to cause damage to the fins, affect the performance of its surface, and then affect the product and quality.

[0006] (2) Affect the efficiency of core assembly equipment

Since a product (automobile heat exchanger core) requires more than 50 sets of fins and flat tubes, although the tube arrangement equipment is used, it is necessary to separate the adhered fins one by one, which takes too much time. Affects assembly speed and becomes a bottleneck restricting production

In addition, the use of piping equipment requires more capital investment, and its structure is complex, occupying a large space, which is not conducive to the promotion and application of this technology

[0007] (3) Automatic fin collection and flat tube arrangement equipment not only requires more capital investment, occupies a larger area, but also is not suitable for fine production of multiple models and varieties

[0008] (4) The technology of the production equipment is complex and needs to be imported, so the cost of using it is very high
