Background
The rise of 5G promotes the production requirement of the 5G antenna base plate to be further, and the bending of the 5G antenna base plate is the central importance of the control of the production quality. At present, V-shaped bending is generally adopted in a traditional bending method, and a metal base plate is firstly subjected to elastic deformation under the pressure of a male die or a female die of a bending machine and then enters a forming process of plastic deformation. At the beginning of the plastic bending, the base plate is free to bend. Along with the pressure applied to the bottom plate by the male die or the female die of the bending machine, the bottom plate is gradually close to the inner surface of the V-shaped groove of the female die, the curvature radius and the bending force arm are gradually reduced, the pressure is continuously applied until the stroke is ended, the female die is in three-point close full contact with the bottom plate, and the V-shaped bending is completed at the moment. When bending, because the metal bottom plate can receive the extrusion of the mould of bending and produce elastic deformation, the contact point of bottom plate and die just can slide along with the going on of technology of bending.
The bottom plate of the bending machine die undergoes two obvious stages of elastic deformation and plastic deformation in the bending process, and a pressure maintaining process is performed in the bending process, so that three crease lines can be formed after the bending process is finished, and the attractive surface of a product is influenced.

Detailed Description
The present invention will now be further described with reference to the accompanying drawings:
according to the attached drawings 1-4, the traceless 5G antenna base plate bending die comprises a male die mechanism 1, a turnover mechanism 2, a female die rotating seat 3 and a base 4; the male die mechanism 1 is arranged above the turnover mechanism 2, the turnover mechanism 2 is movably arranged on the female die rotating seat 3, and the female die rotating seat 3 is arranged above the base 4; and the invertible mechanism 2 has a first inverting mechanism 21 and a second inverting mechanism 22.
The bottom plate is bent by turning the turnover mechanism 2 by utilizing the fulcrum rotation principle. The turnover structure 2 is arranged, so that in the process of pressing the bottom plate down by the male die mechanism 1, two turnover mechanisms in the middle of the female die rotating seat 3 are turned inwards from the lowest point position of the male die mechanism 1 by means of the pressure of the male die mechanism 1, and the bottom plate is bent and formed. Under the working condition, the bottom plate and the female die rotating seat 3 do not generate obvious local sliding friction, but are close to the lowest point of the male die mechanism 1 along the overturning plane, so that the bottom plate is prevented from generating indentation.
According to the attached figure 1, the male die mechanism 1 is used for abutting against the bending part of the bottom plate, and the contact surface of the male die mechanism 1 facing the turnover mechanism 2 is V-shaped. The V-shaped design of the punch mechanism 1 is used for bending the bottom plate into a V-shape.
As shown in fig. 1 to 2, the first turnover mechanism 21 and the second turnover mechanism 22 of the turnover mechanism 2 are arc-shaped, the first turnover mechanism 21 has a first rotating shaft 23 for turnover, the second turnover mechanism 22 has a second rotating shaft 24 for turnover, and one surfaces of the first turnover mechanism 21 and the second turnover mechanism 22 facing the punch mechanism 1 are horizontal surfaces. When the male die mechanism 1 is pressed downwards, the first turnover mechanism 21 and the second turnover mechanism 22 rotate inwards along the direction that the male die mechanism 1 is pressed downwards, so that the bottom plate on the male die mechanism 1 is also pressed downwards along the same direction, and bending and forming are performed.
Referring to fig. 3 and 4, the die turret 3 has a first circular arc-shaped recess 31 and a second circular arc-shaped recess 32 for receiving the invertible mechanism 2. The first turnover mechanism 21 is arranged in the first circular arc-shaped groove 31, and the second turnover mechanism 22 is arranged in the second circular arc-shaped groove 32. The arc-shaped groove is used for fixing the turnover mechanism in the groove, so that the turnover mechanism is prevented from deviating during working, and when the male die mechanism 1 is pressed down, the arc-shaped turnover mechanism just performs inward rotating motion around the rotating shaft in the arc-shaped groove.
According to fig. 1, the lowest position of the punch assembly 1 is on the same center line as the position tangent to the first and second tilting mechanisms 21, 22. The purpose of being designed on the same centerline is to precisely press down the location so that the floor is formed in an offset position.
Referring to fig. 1, the housing 4 has a first card slot 41 and a second card slot 42.
The utility model discloses a theory of operation: utilize first tilting mechanism and second tilting mechanism, inwards overturn by terrace die mechanism minimum position when terrace die mechanism pushes down, make the bottom plate bend and take shape to avoid producing obvious local sliding friction when pushing down, make the bottom plate hug closely the upset plane at the in-process that pushes down, draw close to terrace die mechanism's minimum position simultaneously, can avoid the indentation to appear in the bottom plate.
The utility model discloses a main function: the bending die is applied to bending dies of antenna base plates or other dies needing traceless bending.
