Abstract
The invention discloses a fin straightening method, which comprises the following steps: a. and (4) observation: pre-punching a fin sample through a fin die, and then determining the bending direction of the fin sample by observing the fin sample; b. correcting: and a correction convex die is arranged on the fin die, and a correction bulge is punched on one side of the correction convex die in the direction opposite to the bending direction of the fin to correct the fin. The fin straightening device can be used for straightening bent fins, so that the fins are ensured to be straight and not to be bent, and the collection and the material receiving of the fins are facilitated.
Description
Technical Field
The invention relates to the technical field of fin production methods, in particular to a fin straightening method.
Background
The air conditioner fin die is a high-precision cold-punching progressive die specially used for producing air conditioner fins. The air conditioner fin is a heat sink fin for heat exchange in an air conditioner, and most fin materials are aluminum or copper.
At present, when a fin with a longer length is punched by an air conditioner fin die, the fin can be bent in the length direction due to the influence of various factors, so that the collection and the material receiving of the fin are influenced; thus, a solution is urgently needed.
Disclosure of Invention
The present invention is directed to solving the above problems, and an object of the present invention is to provide a method for straightening a fin.
The purpose of the invention is realized by the following technical scheme:
a method for straightening a fin comprises the following steps:
a. and (4) observation: pre-punching a fin sample through a fin die, and then determining the bending direction of the fin sample by observing the fin sample;
b. correcting: and a correction convex die is arranged on the fin die, and a correction bulge is punched on one side of the correction convex die in the direction opposite to the bending direction of the fin to correct the fin.
In a preferred embodiment of the present invention, the cross section of the straightening male die is circular or square or oval or triangular.
As a preferable aspect of the present invention, the correction punch has a head portion, and the head portion has a circular arc shape.
As a preferable scheme of the invention, the correcting convex die is provided with a head, the end face of the head is a plane, and arc transition surfaces are arranged on two sides of the plane.
As a preferable aspect of the present invention, the straightening male die is mounted on an upper die fixing plate of the fin die.
As a preferable aspect of the present invention, the straightening male die is mounted on a lower die fixing plate of the fin die.
The fin correcting device has the beneficial effects that the bent fins can be corrected, so that the fins are ensured to be straight and not to be bent, and the collection and the material receiving of the fins are facilitated.

Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the embodiments described herein are illustrative only and are not limiting upon the present invention.
Referring to fig. 1 to 4, fig. 1 is a front view of a fin of the present invention after rectification; FIG. 2 is a side view of a fin of the present invention after correction; FIG. 3 is a schematic structural diagram of the cross section of the correcting male die; fig. 4 is a schematic view of the head structure of the correcting male die.
In this embodiment, a method for straightening a fin includes the following steps:
a. and (4) observation: pre-punching a fin sample through a fin die, and then determining the bending direction of the fin sample by observing the fin sample;
b. correcting: a correction male die is mounted on the fin die, and a correction protrusion 2 is punched on one side of the fin 1 in the opposite direction of the bending direction of the fin 1 through the correction male die to correct the fin 1.
Specifically, in this embodiment, the cross section of the correction punch is circular.
Specifically, in this embodiment, the correction convex die has a head portion, and the head portion is circular arc-shaped.
Specifically, in this embodiment, the correcting male die is mounted on an upper die fixing plate of the fin die.
It is worth mentioning that, although the cross section of the correcting punch is circular in the embodiment, the invention is not limited thereto, and the cross section of the correcting punch may be square, oval or triangular.
It should be noted that, although the head of the correction punch is circular in the embodiment, the invention is not limited to this, and the head may also adopt other structural forms, such as designing the end face of the head as a plane, and providing circular transition surfaces on both sides of the plane.
It should be noted that although the correcting punch is mounted on the upper fixing plate of the fin mold in the embodiment, the invention is not limited thereto, and the correcting punch may also be mounted on the lower fixing plate of the fin mold.
The correction method can correct the bent fins 1, so that the fins 1 are flat and not bent, and the collection and the material receiving of the fins are facilitated.
The foregoing embodiments are merely illustrative of the principles and features of this invention, which is not limited to the above-described embodiments, but rather is susceptible to various changes and modifications without departing from the spirit and scope of the invention, which changes and modifications are within the scope of the invention as claimed. The scope of the invention is defined by the appended claims.
