Description

Technical Field

[0001] The utility model relates to the technical field of mold bending processing, in particular to a double-sided bending mold. Background Art

[0002] A bending die is a die used for metal processing. It can bend both sides of a metal sheet at the same time, thereby improving production efficiency and processing accuracy. This die usually consists of two parts: an upper die and a lower die, which correspond to the inner and outer sides of the metal sheet respectively. The upper die is usually designed with a convex shape, while the lower die is designed with a relatively concave shape. When the two are closed, they form a V-shaped space, and the metal sheet is bent in this space.

[0003] After searching, the applicant found that a Chinese patent disclosed "a double-sided bending mold", and its publication number is "CN210231253U". This patent mainly achieves the purpose of improving the bending effect of the workpiece by setting a bending head, a transmission plate and a lower pressure block, etc. After the bending process is completed, it is convenient to reset and remove, and the processing efficiency is improved. It solves the problem that the current double-sided bending mold has poor bending effect, resulting in poor product appearance or damage, increased scrap rate, and easy to get stuck after bending. The bending head is not easy to return to the state, affecting the processing efficiency. However, when processing products, traditional double-sided bending molds process fixed product lengths and widths. When the length and width of the product change, multiple processes are required for bending, which makes the product unevenly stressed during bending, resulting in serious material pulling during product processing. When the product is processed multiple times, the processing quality of the product is reduced, the cost of the processing process is increased, and the low production efficiency of the product is also reduced. Summary of the invention

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0024] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0025] Example 1

[0026] like Figure 1-5 As shown, this embodiment provides a double-sided bending mold, including a top plate 1, three partitions 2 are fixedly connected to the bottom surface of the top plate 1, a first connecting plate 3 is fixedly connected to the bottom surfaces of the three partitions 2, a second connecting plate 4 is fixedly connected to the bottom surface of the first connecting plate 3, and a plurality of ejector rods 5 are slidably connected to the right side of the top surface of the first connecting plate 3;

[0027] The top surfaces of the plurality of push rods 5 are commonly fixedly connected with an upper hitting plate 6, a clamping plate insert 7 is provided on the right side of the bottom surface of the second connecting plate 4, a lower module 8 is provided on the bottom surface of the second connecting plate 4, and a positioning mechanism is provided on the right side of the top surface of the lower module 8.

[0028] Furthermore, the positioning mechanism includes a bending punch 9 arranged on the right side of the top surface of the lower module 8, an upper stripping insert 10 is provided at the lower end of the push rod 5, a guide punch 11 is provided inside the upper stripping insert 10, a lower die insert 12 is provided on the bottom surface of the bending punch 9, and a ejection pin 13 is provided on the left side of the bottom surface of the lower die insert 12.

[0029] The above structural setting avoids the mold from processing and bending the product multiple times when the length and width of the product change, thus ensuring that the force is even during product processing, thereby preventing the product from pulling, improving the quality of the product during processing, reducing the cost of the product during processing, and thus improving the production efficiency of the product.

[0030] like Figure 2-3As shown, in some embodiments, a plurality of high-strength rubbers 15 are fixedly connected between the three partitions 2. The high-strength rubbers 15 facilitate the export of the processed products and improve the convenience of product export. The bottom surfaces of the four high-strength rubbers 15 on the right are fixedly connected to the top surface of the upper plate 6, and the bottom surface of the lower module 8 is fixedly connected to a pad 16.

[0031] like Figure 3-5 As shown, in some embodiments, the bottom surface of the pad 16 is fixedly connected to three vertical poles 17, and the bottom surfaces of the three vertical poles 17 are commonly fixedly connected to a fixing plate 18, and the bottom surface of the fixing plate 18 is provided with anti-slip patterns. The arrangement of the vertical poles 17 improves the structural support strength of the equipment, avoids instability during the processing of the equipment, and improves the stability of the equipment.

[0032] Further, an ejector pin 19 is provided inside the left side of the top surface of the lower module 8. The arrangement of the ejector pin 19 facilitates the export of the processed product.

[0033] Working principle of the utility model: the upper stripping insert 10 and the bending punch 9 are used together to increase the strength of the upper stripping insert 10. When the upper stripping insert 10 presses the material, the bending punches 9 on both sides bend the product to prevent the material from being evenly stressed on both sides when the product is bent. At this time, the upper stripping insert 10 is fixed by the clamping plate insert 7 and the bending punch 9 to prevent the upper stripping insert 10 from shifting. The ejector 5 and the upper plate 6 ensure that the upper stripping insert 10 presses the material during the mold closing process. The ejector pin 13 is set on the lower mold insert 12 to ensure that the product can be smoothly stripped after bending during the mold opening process. The lower mold insert 12 uses the pressure line to ensure that the product reduces the rebound deformation after bending, thereby avoiding secondary processing when processing products of different lengths or widths.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
