specific Embodiment approach 1

[0034] Specific implementation manner one: such as Figure 1 ~ Figure 4 As shown, the steps of a method for forming metal plates by cold pressing are as follows: Step 1. Prefabricated plates: Determine the end shapes of the first plate 1 and the second plate 2 according to the strength, and combine the first plate with a lower yield strength 1 Make convex teeth and a second plate with higher yield strength. 2 Make holes, and determine the shape of the convex teeth or holes of the plate. The shape of the end of the prefabricated plate is like figure 1 As shown (the purpose is to achieve the best self-locking effect after the convex tooth is inserted into the hole after loading and deformation); pre-design the structure of the end of the required connecting plate, and make the insertion end of the first plate 1 into a rectangle according to the design Convex teeth (saw-tooth shape), and the rectangular convex teeth are bent upward, so that the distance between the lower surface of ...

[0035] Specific implementation manner two: such as Figure 5 ~ Figure 7 As shown, the steps of a method for forming a metal sheet by cold pressing deformation are as follows: Step 1. Prefabricating the sheet: According to the yield strength of the first sheet 1 and the second sheet 2, the holes are prefabricated on the second sheet 2 with higher yield strength. And determine the shape of the hole, the shape of the prefabricated plate joint is like Figure 5 As shown (the purpose is to achieve the best connection effect after loading and deformation); Step 2. Pre-connection: Place the pre-connection part of the second plate 2 with prefabricated holes above the pre-connection part of the first plate 1, The two plates after pre-connection such as Image 6 As shown; Step 3. Place the prepared sample on the press workbench: Place the pre-connected first plate 1 and second plate 2 on the press workbench 4, and position it to make the connection part Just at the center of the press wor...

[0036] Specific implementation manner three: such as Figure 8 ~ Figure 14 As shown, the steps of a method for forming metal plates by cold pressing deformation are as follows: Step 1. Prefabrication of plates: Pre-design the convex teeth and grooves at the ends of the plates to be connected, according to the design and the yield strength relationship of the two plates. It is determined that the convex teeth and grooves are processed on the first plate 1 and the second plate 2. The top view of the ends of the two plates is as follows Figure 8 , The cross-sectional view of the ends of the two plates is as Picture 9 (The purpose is to achieve the best connection effect after being loaded and deformed); Step two, pre-connection: insert the convex teeth of the first plate 1 with prefabricated teeth into the grooves of the second plate 2 with prefabricated grooves , The top view after pre-connection is as Picture 10 , The sectional view after pre-connection is as Picture 11 ,; Ste...

Abstract

The invention provides a metal plate deforming, connecting and forming method, belongs to the technical field of metal plate connection and aims at solving various bottleneck problem that existing metal plates have poor bearing capacity in the thickness direction in connection and forming, dropping occurs easily, and the like. The metal plate deforming, connecting and forming method comprises the steps of pre-designing structural style of end portions of plates to be connected, pre-processing convex teeth, holes or grooves with certain shapes at the end portions of the plates, performing matched lap joint of the connecting end portions of two processed plates, arranging a manufactured sample on a work table of press machine, loading connecting positions with a moving-down punch to enable the sample to be subjected to plastic deformation, then maintaining pressure for a certain period of time, enabling the punch to return, taking out connected plates and finishing the connection. By means of the method, the bearing capacity and the reliability in the thickness direction of the connecting positions are improved, and the connection failure defects including dropping and the like can be avoided.

Description

Technical field [0001] The invention relates to a method for connecting two or more layers of the same or heterogeneous plates with equal or unequal thickness, and belongs to the technical field of plate connection. Background technique [0002] Lightweight is currently an important concept and development direction for automotive design and manufacturing. Automotive lightweight is a systematic project, including the development and application of lightweight materials, the design and optimization of lightweight structures, and the improvement of advanced forming technologies that match it. And development. [0003] Sheet connection is one of the effective ways to achieve lightweight in automobile manufacturing and other fields. However, due to obvious differences in material properties and other aspects, it is difficult to formulate and apply the process. Taking the connection of steel and aluminum as an example, the melting point of the two is quite different, which is difficul...
