The directions of the upper, the lower, the left and the right are all the directions shown in the drawings. The specific meaning of the above terms in the embodiments of the present invention will be understood by those of ordinary skill in the art according to specific circumstances.
In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The following describes the process steps of the air conditioner sheet metal part processing method of the present invention with reference to fig. 1 to 5.
As shown in fig. 1, the middle of the air conditioner outdoor unit housing 1 is a circular air guide ring 11, and the air guide ring 11 is used for placing the first sheet metal part 2 and the second sheet metal part 3. It should be noted that fig. 1 is only an example, and it is understood that one or more sheet metal parts may be disposed in the air guiding ring 11. In the traditional processing process, the round air guide ring 11 is directly used as waste material for recycling after being punched down, the material cost is high or the round air guide ring is transferred to another die to be processed into other sheet metal parts, and the number of the dies is large, so that the processing cost is high.
The embodiment of the invention provides a processing method of an air conditioner sheet metal part, which comprises the following steps:
step S1, placing the shell raw material under a die, and stretching or punching the shell raw material in a region corresponding to the air guide ring 11 to form a convex hull and/or a rib position of the first sheet metal part 2. That is, the first sheet metal member 2 is formed by pressing or stretching the cover shell raw material while processing and manufacturing the cover shell raw material by the same die. The structure of the casing stock after the mold operation is shown in fig. 2.
Step S2, the structure of the air guide ring 11 except the first sheet metal part 2 is punched off by means of a die so as to separate the housing 1 from the first sheet metal part 2. The die punches the casing raw material and punches down to form the air guide ring 11, wherein the region corresponding to the first sheet metal part 2 is not punched down, thereby separating the first sheet metal part 2 from the casing 1. Fig. 3 is a structural view of the first sheet metal part 2 separated from the housing 1 after step S2 is performed. It will be appreciated that at this point, the first sheet metal part 2 and the shell material are still on the die, and are processed by the same die in subsequent processes.
And S3, bending and flanging the housing 1 and the first sheet metal part 2 to finish the processing and forming of the first sheet metal part 2 and the housing 1. The sheet metal part after the processing and forming is shown in fig. 4.
According to the processing method of the air conditioner sheet metal part, one or more relatively small sheet metal parts are added to the sheet metal die vacancies with larger sizes by means of the same die, and compared with the traditional processing and manufacturing method, the processing method does not need to be transferred to another die for independently processing the small sheet metal parts, so that raw material consumption is reduced on the premise that the die size is not increased, and material cost and processing cost are saved.
Specifically, step S3 includes bending the side surfaces of the buckle 12 of the housing 1 and the first sheet metal part 2, and flanging the wind guide ring 11 of the housing 1 and the flanging hole of the first sheet metal part 2. The sheet metal part after operation is shown in fig. 5. Then, the side surface of the housing 1 is bent, the air guide ring 11 of the housing 1 is reamed, and the first sheet metal member 2 is bent. As shown in fig. 5, the buckle 12 of the housing 1 is located at the periphery of the air guide ring 11, the buckle 12 of the housing 1 is bent by means of a die to complete the processing operation of the buckle 12, meanwhile, two opposite sides of the first sheet metal part 2 are bent, and hole structures on the housing 1 and the first sheet metal part 2 are turned over, therefore, holes and edges on the housing 1 and the first sheet metal part 2 are turned over and bent simultaneously by means of a movable die and a static die in the same die, and then the movable die is adjusted to perform the final forming operation on other sides and holes of the housing 1 and the first sheet metal part 2.
In step S3, bending the side surfaces of the housing 1 includes bending both side surfaces of the housing 1, and bending the first sheet metal part 2 includes bending both side surfaces of the first sheet metal part 2.
In addition, in order to facilitate the stamping sliding off of the scrap in step S2, step S1 further includes: and pre-stamping the shell raw material.
As shown in fig. 2, in the processing method of an air conditioner sheet metal part provided by the embodiment of the invention, in step S1, convex hulls and rib positions of a first sheet metal part 2 and a second sheet metal part 3 are formed on a shell raw material through a die; correspondingly, in the step S2, punching is carried out, and the housing 1, the first sheet metal part 2 and the second sheet metal part 3 are separated; in step S3, bending and flanging are performed on the housing 1, the first sheet metal part 2 and the second sheet metal part 3. The structures of the first sheet metal part 2 and the second sheet metal part 3 can be the same or different. When the first sheet metal part 2 and the second sheet metal part 3 are identical in structure, the two sheet metal parts can be in mirror image distribution or can be in array distribution. When the first sheet metal part 2 and the second sheet metal part 3 are structurally different, it can be understood that the sizes of the first sheet metal part and the second sheet metal part are smaller than the size of the air guide ring 11.
For example, the first sheet metal part 2 and the second sheet metal part 3 are square parts, and the central axis of the first sheet metal part 2 and the central axis of the second sheet metal part 3 are positioned on the central line of the shell raw material. Therefore, the dies are symmetrically distributed along the middle line in an opposite mode, and the operation is more convenient.
As shown in fig. 2, in step S1, the mold forms an annular convex hull and/or rib position in the corresponding area of the air guide ring 11 of the housing raw material by punching. For example, the convex hull may be formed by stamping, or the convex hull and the rib may be formed at the same time in the corresponding region of the wind guiding ring 11 by stamping, specifically according to the structure of the first sheet metal part 2. The annular convex hull and/or the rib position may be a closed shape formed by a circular ring shape or other wire bodies, which is not particularly limited.
As shown in fig. 3, one side of the annular convex hull and/or rib is flat and pre-stamped on this flat side to form a gap for subsequent stamping.
In the processing method of the air conditioner sheet metal part provided by the embodiment of the invention, the structure of the air guide ring 11 except the first sheet metal part 2 is punched by means of the die in the step S2, specifically, the area to be punched is cut by means of the die, then punching is carried out to slide, and the buckles 12 are formed by punching in the circumferential direction of the air guide ring 11. After the area to be punched is cut through the die, the punching effect is optimized.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
