DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The purpose of the present invention is to provide a die forging forming die for connecting corner pieces for containers to solve the problems existing in the above-mentioned prior art. The die has a novel structure, strong practicality, and can produce forgings with superior performance.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-4 As shown: This embodiment provides a die forging die 100 for connecting corner pieces of containers, which is used to manufacture thin plate bent forgings, including an upper forging die 1 and a lower forging die 2. The upper forging die 1 is located directly above the lower forging die 2. The projections of the upper forging die 1 and the lower forging die 2 along the horizontal plane are both rectangular. The upper forging die 1 is provided with an upper die cavity 3, which is located at a non-center position of the lower end face of the upper forging die. The lower forging die 2 is provided with a lower die cavity 4, which is located at a non-center position of the upper end face of the lower forging die. The upper forging die 1 and the lower forging die 2 are arranged opposite to each other, and the upper die cavity 3 and the lower die cavity 4 form a forging die cavity. The shape of the forging die cavity matches the shape of the part. A burr bridge mouth 5 is provided on the outer side of the upper die cavity 3, and a first burr structure 6 is provided on the outer side of the burr bridge mouth 5. A second burr structure 7 is provided on the outer side of the lower die cavity 4. The burr bridge mouth 5 and the first burr structure 6 are arranged opposite to the second burr structure 7, and the first burr structure 6 and the second burr structure 7 form a burr bin. The container corner connector die forging die 100 of this embodiment utilizes the module space rationally, has a novel structure, is highly practical, and can effectively improve production efficiency. The embodiment achieves one-piece forging, and the performance of the forging is superior to that of the casting.

[0027] Specifically, in this embodiment, the first burr structure 6 is protruded from the upper die cavity 3 , and the burr bridge 5 is protruded from the first burr structure 6 ; the second burr structure 7 is protruded from the lower die cavity 4 .

[0028] In this embodiment, when the upper forging die 1 and the lower forging die 2 are fastened together, a gap exists between the burr bridge 5 and the second burr structure 7. Both the first burr structure 6 and the second burr structure 7 are curved surfaces, and both the first burr structure 6 and the second burr structure 7 are bent outwards.

[0029] In this embodiment, the front end face and the rear end face of the lower forging die 2 are provided with notches, and the notches are communicated with the flash bin.

[0030] In this embodiment, the container corner connection piece forging die 100 also includes a limiting structure 8, which includes a first limiting portion 9 and a second limiting portion 10. The first limiting portion 9 is located on the lower surface of the upper forging die 1, and the second limiting portion 10 is located on the upper surface of the lower forging die 2. The first limiting portion 9 matches the second limiting portion 10.

[0031] In this embodiment, there are four first limiting parts 9 and four second limiting parts 10. The four first limiting parts 9 are located at the four corners of the upper forging die 1, and the four second limiting parts 10 are located at the four corners of the lower forging die 2. The first limiting part 9 is a concave lock buckle, and the second limiting part 10 is a convex lock buckle.

[0032] In this embodiment, when the upper forging die 1 and the lower forging die 2 are buckled together, there is a gap between each first limiting portion 9 and each corresponding second limiting portion 10 .

[0033] In this embodiment, a first dovetail structure 11 is provided at the top of the upper forging die 1, and a second dovetail structure 12 is provided at the bottom of the lower forging die 2. The first dovetail structure 11 and the second dovetail structure 12 are both provided with assembly key grooves 13. Key blocks are inserted into the assembly key grooves 13 of the upper forging die 1 and the lower forging die 2 to limit the forward and backward movement of the container connecting corner piece forging die 100.

[0034] In this embodiment, each end face of the upper forging die 1 is provided with a first lifting hole 14, and each end face of the lower forging die 2 is provided with a second lifting hole 15. In this embodiment, the front and rear ends of the upper forging die 1 are each provided with a first lifting hole 14 opposite and centered thereon, and the left and right end faces of the upper forging die 1 are each provided with two first lifting holes 14 opposite and centered thereon; the front and rear ends of the lower forging die 2 are each provided with a second lifting hole 15 opposite and centered thereon, and the left and right end faces of the lower forging die 2 are each provided with two second lifting holes 15 opposite and centered thereon; the first lifting holes 14 and second lifting holes 15 on each end face correspond to each other. The first lifting holes 14 and second lifting holes 15 facilitate the lifting and turning of the container corner piece forging die 100 during actual production.

[0035] The container corner fitting 16 produced using the container corner fitting die forging die 100 of this embodiment has a right-angled shape, unequal side lengths, and varying thickness, with thicker sections in the middle and thinner sections at the ends. The container corner fitting die forging die 100 features front-to-back symmetrical curved parting, with the upper die cavity 3 and lower die cavity 4 being asymmetrical.

[0036] When the container connecting corner piece forging die 100 of this embodiment is used to manufacture the container connecting corner piece 16, the container connecting corner piece forging die 100 is first shipped using the first lifting hole 14 and the second lifting hole 15. During operation, the blank is heated and placed in the forging die for extrusion molding. During the molding process, after the blank flows and fills the forging die, the excess material will enter the first burr structure 6 and the second burr structure 7 through the gap below the burr bridge mouth 5.

[0037] Compared with the products currently made by casting technology, the container connecting corner fittings 16 forged by the container connecting corner fitting die forging die 100 of this embodiment are forged as a whole, with uniform internal structure, which improves the strength and fatigue resistance of the product; the container connecting corner fitting die forging die 100 of this embodiment reasonably utilizes the space of the module, has a novel structure, strong practicality, and can effectively improve production efficiency; the limiting structure 8 of the container connecting corner fitting die forging die 100 of this embodiment plays a guiding role during forging, and can produce forgings with higher precision under the condition of poor forging hammer precision, and is convenient for installation and positioning.

[0038] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
