Detailed Implementation

[0029] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0030] like Figures 1 to 6 As shown, this embodiment proposes a bending mechanism, including a first bending component 11, for stamping a right-angled product 12 into an acute-angled shape, wherein the product 12 has a first connecting arm 13 and a second connecting arm 14.

[0031] The first bending assembly 11 includes a first support block 15, a movable pressure block 16, and a drive block 17, wherein the movable pressure block 16 is located between the first support block 15 and the drive block 17;

[0032] The first support block 15 has a flat upper surface and a first inclined surface 18 on the side of the first support block 15 facing the movable pressure block 16. The angle between the first inclined surface 18 and the upper surface of the first support block 15 is an acute angle. The first connecting arm 13 of the product 12 is disposed on the upper surface of the first support block 15 through a pressing column 19. The second connecting arm 14 of the product 12 is located between the first support block 15 and the movable pressure block 16.

[0033] The movable pressure block 16 is provided with a second inclined surface 20, which is parallel to the first inclined surface 18. The first inclined surface 18 and the second inclined surface 20 are used to press the second connecting arm 14.

[0034] Drive block 17, which is used to drive the movable pressure block 16 to move, so that the movable pressure block 16 moves closer to or away from the first support block 15.

[0035] The first bending assembly 11 in this solution can stamp the right-angled product 12 into an acute-angled shape, effectively overcoming the technical difficulties. The first connecting arm 13 of the product 12 is set on the upper surface of the first support block 15 through the clamping column 19. The second connecting arm 14 of the product 12 is located between the first support block 15 and the moving pressure block 16. At this time, the second connecting arm 14 is a vertical arm. The driving block 17 drives the moving pressure block 16 to move toward the first support block 15, so that the second inclined surface 20 of the moving pressure block 16 squeezes the second connecting arm 14 of the product 12. When the second connecting arm 14 is in contact with the first inclined surface 18, the included angle between the second connecting arm 14 and the first connecting arm 13 is an acute angle.

[0036] In this solution, when the raw material of product 12 is in its initial state, the first connecting arm 13 and the second connecting arm 14 are located on the same horizontal plane. The raw material of product 12 is first processed by the third bending assembly 29 to form an obtuse angle shape, then processed by the second bending assembly 30 to form a right angle shape, and finally processed by the first bending assembly 11 to form an acute angle shape.

[0037] The third bending assembly 29 includes a second support block 31. The two adjacent surfaces at the upper end of the second support block 31 are a plane and an inclined plane, and the included angle between the two surfaces is an obtuse angle.

[0038] The second bending assembly 30 includes a third support block 33, the upper end of which is a plane for supporting the first connecting arm 13 of the product 12. A second stamping column 34 is located above the third support block 33, for stamping the second connecting arm 14 of the product 12 downwards. Since the side of the third support block 33 is a vertical surface, it limits the angle of the second connecting arm 14 after bending, ensuring that the angle between the second connecting arm 14 and the first connecting arm 13 forms a right angle.

[0039] In one embodiment of this invention, the height of the movable pressure block 16 is greater than the height of the first support block 15.

[0045] In one embodiment of this invention, the upper end of the first inclined guide groove 23 in the inclined direction is close to the movable pressure block 16, and the lower end of the first inclined guide groove 23 in the inclined direction is far away from the movable pressure block 16.

[0046] When the drive column 21 pushes the drive block 17 downward, under the guidance of the first inclined guide groove 23 and the second inclined guide groove 25, the moving pressure block 16 moves toward the first support block 15, thereby squeezing the product 12.

[0047] Furthermore, the elastic reset member 22 includes a spring 39 and a push rod 40, the top of which supports the drive block 17, and the bottom of which is fixed with the spring 39.

[0048] In addition, this application also proposes a mold including the aforementioned bending mechanism.

Additionally, the movable pressure block 16 is slidably disposed in the second mounting groove 36 in the horizontal direction, and the driving block 17 is slidably disposed in the second mounting groove 36 in the vertical direction. The lower end of the lower die assembly 28 is provided with a mounting opening 37 communicating with the second mounting groove 36 for mounting the elastic reset member 22. Furthermore, both the upper die assembly 27 and the lower die assembly 28 are composed of multiple model blocks.

[0052] Furthermore, the lower end of the lower mold assembly 28 is provided with a support leg 38.

[0053] In addition, this application also proposes a punch press for mounting the aforementioned mold.
