A refrigerator sill forming mold 10 according to an embodiment of the present invention will be described with reference to the accompanying drawings. As shown in fig. 1 and 2, the refrigerator sill forming die 10 according to the embodiment of the present invention includes a lower die holder 111, an upper die holder 112, a first bending die 120, a second bending die 130, a third bending die 140, a pressing member 150, and a first bending punch 160.
The first bending female die 120, the second bending female die 130 and the third bending female die 140 are arranged on the lower die holder 111, the second bending female die 130 is located between the first bending female die 120 and the third bending female die 140 in the first horizontal direction, and the upper surface of the second bending female die 130 is located below the upper surface of the first bending female die 120 and the upper surface 142 of the third bending female die 140, so that an accommodating cavity is defined between the first bending female die 120, the second bending female die 130 and the third bending female die 140. This first horizontal direction is indicated by arrow B in fig. 1.
A first side surface 141 of the third bending female die 140 adjacent to the first bending female die 120 is an inclined surface, an included angle between the first side surface 141 and the vertical direction is less than or equal to a first preset value, and a first portion 143 of the upper surface 142 of the third bending female die 140 adjacent to the first side surface 141 is an inclined surface. The pressing member 150 is opposite to the first bending die 120 in the up-down direction.
The first bending punch 160 is provided on the upper die base 112, the first bending punch 160 has a convex portion 161 opposed to the second bending die 130 in the up-down direction, and the first bending punch 160 has a first surface 162 engaged with the first side face 141 and a second surface 163 engaged with the first portion 143.
The operation of the refrigerator sill molding die 10 according to the embodiment of the present invention will be described with reference to fig. 1, 2 and 7. First, a sheet may be placed on the upper surface of the second bending die 130. The holding member 150 may then be moved downwardly to hold the web against the second bending die 130 to prevent movement of the web during clamping. Finally, the first bending punch 160 is moved downwards to press a portion of the material sheet into the receiving cavity.
Wherein a portion of the web contacting the upper surface of the second bending die 130 may constitute the joining portion 213, a portion of the web contacting the side surface of the first bending die 120 may constitute the second sub-clamping portion 212, a portion of the web contacting the first side surface 141 of the third bending die 140 may constitute the first sub-clamping portion 211, and a guide portion 220 of the first portion 143 of the upper surface 142 of the third bending die 140.
Since the refrigerator sill molding die 10 according to the embodiment of the present invention is used, the clamping part 210 and the guide part 220 can be processed. Because the included angle between the first side surface 141 and the vertical direction is less than or equal to the first preset value, the processed clamping portion 210 can be closed, and the closing process of the clamping portion 210 is not required.
According to the refrigerator bottom beam forming die 10 provided by the embodiment of the invention, the included angle between the first side surface 141 and the vertical direction is smaller than or equal to the first preset value, so that the forming processing and the closing processing can be simultaneously carried out. Therefore, six procedures of the refrigerator bottom beam manufacturing method can be reduced to five procedures, so that the procedures (the closing machining procedure is omitted), the dies (the closing dies are omitted), the production efficiency of the refrigerator bottom beam is improved, the production cost of the refrigerator bottom beam is reduced, and the number of operators (operators for operating the closing dies are not required) is reduced.
Therefore, by using the refrigerator bottom beam forming mold 10 according to the embodiment of the invention, the process is simplified, the mold is reduced, the production efficiency of the refrigerator bottom beam is improved, the production cost of the refrigerator bottom beam is reduced, and the number of operators is reduced.
As shown in fig. 1 to 9, in some embodiments of the present invention, the refrigerator sill forming die 10 may include a lower die holder 111, an upper die holder 112, a first bending die 120, a second bending die 130, a third bending die 140, a holding member 150, a first bending punch 160, a second bending punch 170, a lower bolster 181, an upper clamping plate 182, and an upper cover plate 183. Specifically, the pressure holding member 150 may be a nitrogen spring.
The lower bolster plate 181 may be disposed on the lower bolster seat 111, and the first bending female die 120, the second bending female die 130, and the third bending female die 140 may be disposed on the lower bolster plate 181, that is, the first bending female die 120, the second bending female die 130, and the third bending female die 140 may be disposed on the lower bolster seat 111 through the lower bolster plate 181. The lower backing plate 181 is arranged on the lower die holder 111, so that the impact force on the lower die holder 111 during die assembly can be greatly reduced, and the structure of the refrigerator bottom beam forming die 10 can be more reasonable.
The second bending die 130 is located between the first bending die 120 and the third bending die 140 in the first horizontal direction, and an upper surface of the second bending die 130 may be located below an upper surface of the first bending die 120 and an upper surface 142 of the third bending die 140, so that a receiving cavity is defined between the first bending die 120, the second bending die 130 and the third bending die 140.
The first side surface 141 of the third bending concave die 140 adjacent to the first bending concave die 120 may be an inclined surface, an included angle between the first side surface 141 and the vertical direction may be less than or equal to the first preset value, that is, an included angle between the first side surface 141 and the horizontal plane may be greater than or equal to the second preset value, and a sum of the first preset value and the second preset value may be equal to 90 degrees.
The first preset value may be determined according to a specific shape, size, etc. of the bottom beam 20 of the refrigerator. Preferably, the included angle between the first side surface 141 and the vertical direction may be greater than or equal to 5 degrees and less than or equal to 30 degrees. More preferably, the included angle between the first side surface 141 and the vertical direction may be greater than or equal to 10 degrees and less than or equal to 20 degrees.
In one embodiment of the present invention, as shown in fig. 1 and 2, the upper edge of the first side 141 may be away from the first bending die 120 relative to the lower edge of the first side 141. Therefore, the structure of the refrigerator bottom beam forming die 10 can be more reasonable.
As shown in fig. 1 and 2, a first portion 143 of the upper surface 142 of the third bending die 140 adjacent to the first side 141 may also be a bevel. The angle of the first portion 143 of the upper surface 142 from the vertical may be greater than the first preset value, i.e., the angle of the first portion 143 of the upper surface 142 from the horizontal may be less than the second preset value.
The upper clamp plate 182 can be disposed on the upper die base 112, and the upper die base 112 can be disposed on the upper cover plate 183. Therefore, the structure of the refrigerator bottom beam forming die 10 can be more reasonable.
As shown in fig. 1 and 2, in some examples of the invention, the first bending punch 160 and the second bending punch 170 may be disposed on the upper clamp plate 182, i.e., the first bending punch 160 and the second bending punch 170 may be disposed on the upper die base 112 through the upper clamp plate 182. Here, the first bending die 120 may be located between the second bending punch 170 and the second bending die 130 in the first horizontal direction, and the holder 150 may be opposite to the first bending die 120 in the up-down direction.
By providing the second bending punch 170 and positioning the first bending die 120 between the second bending punch 170 and the second bending die 130 in the first horizontal direction, the sheet can be bent by 90 degrees by the second bending punch 170 during die assembly, so that the first sub-bent portion 231 and the second sub-bent portion 232 are formed.
Therefore, the refrigerator bottom beam forming die 10 can simultaneously perform forming processing, closing processing and 90-degree bending processing, so that six processes of the refrigerator bottom beam manufacturing method can be reduced to four processes. Therefore, the process can be further simplified (the closing-up processing procedure and the 90-degree bending processing procedure are omitted), the dies are further reduced (the closing-up die and the 90-degree bending die are omitted), the production efficiency of the refrigerator bottom beam is further improved, the production cost of the refrigerator bottom beam is further reduced, and the number of operators is further reduced (operators for operating the closing-up die and the 90-degree bending die are not required to be arranged).
Specifically, the width of the first sub-bending portion 231 may be substantially equal to the width of the first bending die 120, and the distance between the first bending die 120 and the second bending punch 170 in the first horizontal direction may be substantially equal to the thickness of the web.
The first bending punch 160 may have a protrusion 161 vertically opposite to the second bending die 130, and the first bending punch 160 may have a first surface 162 engaged with the first side 141 and a second surface 163 engaged with the first portion 143. Specifically, when the refrigerator sill mold 10 is clamped, the first sub-clamping portion 211 may be clamped between the first side 141 and the first surface 162, and the guide portion 220 may be clamped between the first portion 143 and the second surface 163.
In an example of the present invention, the second bending die 130 may be movably provided on the lower die base 111 in an up-down direction. It is thereby possible to move the second bending die 130 upward after the mold opening, so that the web is ejected by the second bending die 130.
As shown in fig. 1 and 2, in a specific example of the present invention, the second bending die 130 may be configured with a first stepped portion 131, and the third bending die 140 may be configured with a second stepped portion 144. Wherein the second step portion 144 may be located above the first step portion 131, and the second step portion 144 may be engaged with the first step portion 131. Therefore, the upward movement distance of the second bending female die 130 can be limited, and the structure of the refrigerator sill molding die 10 can be more reasonable.
