Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Example 1:

referring to fig. 1 and 2, an aluminum foil lunch box with good compression resistance effect, wherein a box body 1 can be in the shape of a conical round table or a trapezoidal table, in order to realize stamping and demoulding, a box eave 2 is arranged at the large end of the conical round table or the trapezoidal table, and in order to increase the strength of the box body 1, a plurality of groups of connecting creases are arranged along the axial direction of the box body 1, when the aluminum foil lunch box is produced, the box body 1 and the box eave 2 are formed by one-time stamping, the stamping time can be shortened, the production efficiency is improved, the aluminum foil lunch box also comprises a connecting surface 3 for connecting the box body 1 and the box eave 2, the connecting surface 3 can be smoothly connected with the transitional box body 1 and the box eave 2, the connecting surface 3 is arranged to have a certain demoulding angle or radian, the aluminum foil paper can be prevented from being damaged during stamping, demoulding is also convenient, the adhesion is reduced, and a first reinforcing surface 4 and a second reinforcing surface 5 are symmetrically arranged on the connecting surface 3, the first reinforcing surface 4 and the second reinforcing surface 5 are in smooth transition connection through the first transition surface 6, when the punch forming is carried out, the first reinforcing surface 4 and the second reinforcing surface 5 are close to each other, the first transition surface 6 protrudes outwards under the punching force, the three form reinforcing ribs, when the lunch box is viewed from the outer side of the lunch box, the reinforcing ribs formed by the first reinforcing surface 4 and the second reinforcing surface 5 are both triangular, and the triangular structure has good stability, so when a heavy object is placed in the lunch box, the bending phenomenon of the box eave 2 can not occur when the box eave 2 is held by hands, or when more lunch boxes are stacked together, the lunch box can not be crushed, the compression resistance and the bearing weight of the lunch box can be enhanced, the area of the formed triangular structure occupying aluminum foil paper is relatively small, the aluminum foil paper can be prevented from being torn during the punch forming, the first transition surface 6 smoothly and transitionally connects opposite sides of the two groups of the triangular structure, the right-angle side or the sharp-angle side is avoided, the triangle is a right-angle triangle, the stamping and the demolding are facilitated, the shape of the reinforcing rib formed by the stamping is regular, and the reinforcing rib can bear larger weight and pressure, when the triangle is of other types, the reinforcing rib formed by the triangle is strange in shape and not easy to demold, and even the stamping can not be achieved.

Here, when punching and forming the aluminum foil lunch box, along with the upper punch die gradually pushes down, first enhancement face 4 and second enhancement face 5 are stood gradually by flattening, when the lunch box volume is little, like egg tart box, its cavity capacity that forms the strengthening rib is 0.02ml, so the lug on its punch die is also correspondingly less, in order to strengthen the intensity of lug on the punch die, lengthen its life and reduce the manufacturing difficulty, should make first enhancement face 4 and second enhancement face 5 form the crossing face that the contained angle is 135 °, when the lunch box volume is great, like lunch box, soup box and dish box, the cavity capacity of strengthening rib that it forms is 0.08ml, further in order to avoid forming the straight edge angle in the crossing of first enhancement face 4 and second enhancement face 5, adopt first transition face 6 of circular arc to strengthen face 4 and second enhancement face 5 transition connection, can reduce the aluminium foil paper area that occupies as far as possible, and can make the first enhancement face 4 and second enhancement face 5 between smooth, avoid having the transition between right angle edge or the aluminium foil edge when being opened excessively, lead to the sharp angle.

Example 2:

referring to fig. 1 and fig. 3, the same as embodiment 1, except that the included angle between the fifth reinforcing surface 402 and the sixth reinforcing surface 502 is selected to be 30 °, at this time, the cross-sectional shape is a trapezoid with a rounded corner, the third transition surface 602 is composed of two arc surfaces and a plane tangent to the two arc surfaces, and is used to connect the fifth reinforcing surface 402 and the sixth reinforcing surface 502, so that the depth of the reinforcing rib can be properly reduced, i.e. the pulling of the aluminum foil paper can be reduced, and the forming quality of the aluminum foil lunch box can be improved, which is mainly suitable for the situation that the volume of the aluminum foil lunch box is large, compared with embodiment 1, the volume of the cavity formed by the fifth reinforcing surface 402 and the sixth reinforcing surface 502 is slightly larger than the volume of the cavity formed by the first reinforcing surface 4 and the second reinforcing surface 5, so the strength of the lunch box is also larger than the strength of the lunch box formed by the first reinforcing surface 4 and the second reinforcing surface 5.

Example 3:

referring to fig. 4 and 5, the same as embodiment 2, except that as the upper punch press is gradually pressed down, the third reinforcing surface 401 and the fourth reinforcing surface 501 are stopped when they are parallel to each other, and similarly, in order to avoid generating a straight edge, the circular arc-shaped second transition surface 601 is used to smoothly and transitionally connect the third reinforcing surface 401 and the fourth reinforcing surface 501, compared with embodiment 1 and embodiment 2, the protruding block structure of the punch press for forming the reinforcing ribs with the third reinforcing surface 401 and the fourth reinforcing surface 501 parallel to each other is simpler, the manufacturing is more convenient, and the strength of the reinforcing ribs is far better than those of the other two, and the reinforcing ribs are not easily deformed by stretching, but the punching quality and the drawing smoothness of the two embodiments are better than those of the lunch box in embodiment 3, and the reinforcing ribs are mainly used for manufacturing the lunch boxes with larger containing quality, have better stability, and are not easily crushed and deformed during transportation and stacking.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
