Description
Technical field
The utility model relates to the technical field of refrigerator, the small radian door shell window of especially a kind of household electrical appliance is bent into
Type structure.
Background technique
The front of the metal door shell of existing household electrical appliance is often convex outward, and the front of metal door shell is provided with aperture, opens
The periphery in hole is equipped with flange, but often occurs slight crack on flange, and the corner of aperture is often cracked, and Curved surface metal door shell is caused
Shape after molding is unstable.
Utility model content
The purpose of this utility model is to provide it is a kind of it is simple and reasonable for structure, can be reduced after flange because curved surface door shell is made
It is excessive at the drawing force and stress of flange, lead to that the small radian shape of door shell is unstable, stretches the household electrical appliance that happen of modification
Small radian door shell window bending and molding structure.
Purpose of the utility model is realized as follows:
A kind of small radian door shell window bending and molding structure of household electrical appliance, including metal door shell, the metal door shell
Front is the convex outward of small radian, and the front of the metal door shell is equipped with window, and the periphery of the window is equipped with in-flanges, institute
State that in-flanges is arc-shaped, the radian of the in-flanges is greater than or equal to the radian of convex outward, and the length of the in-flanges is equal to
Or it is greater than the corresponding periphery side length of window.The metal door shell of the utility model just pre-sets varus when stamping out window
The radian on side is greater than or equal to the radian of convex outward, and the length of the in-flanges is equal to or more than the length that window corresponds to side length
Degree, the total length of in-flanges are greater than the perimeter of window, cause flange so as to avoid the external form after flange because of the small radian of door shell
Drawing force and stress it is excessive, it is unstable to avoid the small radian shape of door shell, or even cause occur slight crack at pressing and bending.This reality
The periphery with small radian is punched into punching with the periphery of novel window, after flange, which also has
There is small radian.
The utility model can be that can improve further below.
The front of the metal door shell is in ︵ shape.
The in-flanges includes big in-flanges and corner in-flanges, and the big in-flanges is circumferentially arranged in window along window
Periphery, corner in-flanges is set to the corner of window, and the corner in-flanges connect with big in-flanges.
The bending length of the corner in-flanges is less than the bending length of big in-flanges.The corner of the window of the utility model
Shorter corner in-flanges is set, the side length for lengthening the punching and edge-cutting of this corner is played, also reduces the metallic door of flanging forming
Shell is generated in the drawing and forming amount of this position, more reduction stress.
The sum of the big in-flanges and side length of corner in-flanges are equal to or more than its corresponding window perimeter length,
Flange after such setting reduction flange draws side and stress excessive, and the small radian shape for avoiding door shell is unstable, reduces
Modification is drawn under the action of stress after punch forming.
The big in-flanges with corner in-flanges be it is one time punching molded, Forming Quality is good, and bending shape is stablized.
Corner in-flanges is equipped with flange notch, when metal door shell punching and edge-cutting (before window flange), corner in-flanges pair
Side is answered just to be punched into flange notch, to reduce the sideline drawing crack of corner in-flanges, the more effective flange internal stress that reduces is produced
It is raw.
The flange notch is arc-shaped slot, and arc-shaped slot plays the side length for lengthening the punching and edge-cutting of this corner, also reduces
The metal door shell of flanging forming is generated in the drawing and forming amount of this position, more reduction stress.
The window is rectangular window, and the window has big in-flanges described in multistage, two sections of adjacent big in-flanges
It is to be connected by the corner in-flanges of window corner.
The beneficial effects of the utility model are as follows:
(1) the utility model, which has, is arranged windowing among small radian door shell, windowing surrounding is provided with flange, in order to
Make the better punch forming of this window, by radian just being gone out in punching sideline, and make die cut edge when plate blanking is punched
The side length of line is long or longer as the length of corresponding position door shell radian,
(2) corner position is just punched into the small flange of notch when plate blanking is punched；By designing above, effectively avoid
There is the case where cracking rupture in flange, and the more effective stress that reduces generates, and guarantees molding stability.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
As shown in Fig. 1 to Fig. 6, a kind of small radian door shell window bending and molding structure of household electrical appliance, including metal door shell
1, the front of the metal door shell 1 is the convex outward of small radian, and the front of the metal door shell 1 is equipped with window 11, the window
The periphery of mouth 11 is equipped with in-flanges 12, and the in-flanges 12 is arc-shaped, and the radian of the in-flanges 12 is greater than or equal to outer evagination
The radian in face.When stamping out window 11, the radian for just pre-setting in-flanges 12 is greater than the metal door shell 1 of the utility model
Or the radian equal to convex outward, the length of the in-flanges 12 are equal to or more than the length that window corresponds to side length, in-flanges
Total length is greater than the perimeter of window, and the drawing force and stress of flange is caused so as to avoid the external form after flange because of the small radian of door shell
It is excessive, it is unstable to avoid the small radian shape of door shell, or even cause occur slight crack at pressing and bending.The window of the utility model
11 periphery has been punched into the periphery with small radian in punching, and after flange, which also has small radian.
As the more specific technical solution of the utility model.
The front of the metal door shell 1 is in ︵ shape.
The in-flanges 12 includes big in-flanges 121 and corner in-flanges 122, and the big in-flanges 121 is along window 11
The periphery of window 11 is circumferentially set, corner in-flanges 122 is set to the corner of window 11, the corner in-flanges 122 with it is big
In-flanges 121 connects.
The bending length of the corner in-flanges 122 is less than the bending length of big in-flanges 121.The window of the utility model
Shorter corner in-flanges 122 is arranged in 11 corner, plays the side length for lengthening the punching and edge-cutting of this corner, also reduce flange at
The metal door shell 1 of shape is generated in the drawing and forming amount of this position, more reduction stress.
The sum of the big in-flanges 121 and side length of corner in-flanges 122 are equal to or more than its corresponding window 11
Perimeter length, such flange being arranged after reducing flange draw side and stress excessive, avoid the small radian shape of door shell not
Stablize, draws modification under the action of stress after reducing punch forming.
The big in-flanges 121 and corner in-flanges 122 are one time punching molded.
The corner in-flanges 122 is equipped with flange notch 123, when metal 1 punching and edge-cutting of door shell (before 11 flange of window),
122 corresponding sides of corner in-flanges have just been punched into flange notch 123, to reduce the sideline drawing crack of corner in-flanges 122, more
Effectively reduce the generation of flange internal stress.
The flange notch 123 is arc-shaped slot, and arc-shaped slot plays the side length for lengthening the punching and edge-cutting of this corner, also subtracts
The metal door shell 1 of few flanging forming is generated in the drawing and forming amount of this position, more reduction stress.
The window 11 is rectangular window 11, and the window 11 has a big in-flanges 121 described in multistage, adjacent two sections
Big in-flanges 121 is connected by the corner in-flanges 122 of 11 corner of window.
