Description
Technical Field
[0001] This utility model relates to the field of flange structure technology, and in particular to a slider-driven upper flange structure. Background Technology
[0002] An upward flange generally refers to a structure formed by bending or rolling the edge of a part upwards through a specific process. For example, some thin metal sheet parts may undergo upward flange treatment to increase the strength and rigidity of the edge, or to be used for installing seals or connecting other components.
[0003] In existing technologies, the punching and flanging processes for the same part are usually completed by two machines or require two sets of molds, namely punching mold and flanging mold, to perform these two operations separately. The two processes not only lead to a longer production cycle and increased production costs, but also require two positioning operations, which can easily lead to a decrease in accuracy. In view of this, we propose a slider-driven flanging structure. Utility Model Content

[0025] Please see Figure 1-6 This utility model provides a technical solution: a slider-driven upper flange structure, including an upper mold 1 and a lower mold 2. A mounting frame 3 is fixedly connected to the upper surface of the lower mold 2, and a first wedge block 4 is slidably connected to the bottom of the mounting frame 3. A pressure block 5 is fixedly connected to the lower surface of the upper mold 1, and a second wedge block 6 is fixedly connected to the lower surface of the pressure block 5. The surfaces of the second wedge block 6 and the first wedge block 4 adjacent to each other are both set as inclined surfaces. A third wedge block 7 is slidably connected to the inner wall of the mounting frame 3, and the surfaces of the third wedge block 7 and the first wedge block 4 adjacent to each other are both set as inclined surfaces. The first wedge block 4 is closer to the third wedge block 7. Two first L-shaped limiting plates 8 are fixedly connected to one side surface of the third wedge block 7. A displacement plate 9 is fixedly connected to the side surface of the third wedge block 7 near the first wedge block 4. The displacement plate 9 is slidably connected between the two first L-shaped limiting plates 8. A first groove 10 is opened on the right side surface of the first wedge block 4. A reset adjustment component is set inside the first groove 10. By utilizing the normal pressing process of the upper mold 1, the second wedge block 6, the first wedge block 4 and the third wedge block 7 can automatically complete the flanging of the workpiece. The whole operation is fully automated without human intervention. At the same time, there is no need for secondary positioning, which reduces the number of positioning times and the production time of the workpiece.
[0026] Furthermore, the reset adjustment assembly includes a first nitrogen spring 11, which is fixedly connected to the inner wall of the first groove 10. The right end of the first nitrogen spring 11 extends out of the outside of the first groove 10 and is fixedly connected to the inner wall of the mounting frame 3. An embedding groove 12 is provided on the inclined side of the first wedge block 4 near the second wedge block 6. An adjustment block 13 is slidably connected inside the embedding groove 12. Two second L-shaped limiting plates 14 are fixedly connected to the surface of the adjustment block 13. A positioning plate 15 is fixedly connected to the lower surface of the two second L-shaped limiting plates 14. A contact plate 16 is slidably connected between the two second L-shaped limiting plates 14. A fixing bolt 17 is provided on the contact plate 16. The contact plate 16 is fixedly connected to the adjustment block 13 through the fixing bolt 17. A fourth wedge block 18 is slidably connected to the bottom wall of the embedding groove 12. The upper surface of block 18 contacts the lower surface of adjusting block 13. The lower surface of adjusting block 13 is also set as an inclined surface. The inner wall of the embedded groove 12 is rotatably connected to a threaded rod 19. The end of the threaded rod 19 rotates through the outside of the first wedge block 4. The end of the threaded rod 19 located outside the first wedge block 4 is fixedly connected to an adjusting knob 20. The inner wall of the embedded groove 12 has a second groove 21. The inner wall of the second groove 21 is fixedly connected to a second nitrogen spring 22. The end of the second nitrogen spring 22 is fixedly connected to the fourth wedge block 18. The third wedge block 7 is fixedly connected to a flange insert 23. The movement of the fourth wedge block 18 can drive the adjusting block 13 to move, thereby adjusting the initial interval of the first wedge block 4 of the second wedge block 6, thereby adjusting the final height of the third wedge block 7. The flange angle can be quickly adjusted without changing the mold.
[0027] The nitrogen spring is an existing structure and will not be described in detail as it is not a major structure.
[0028] Working principle: During punching and flanging, the upper die 1 drives the punching drill bit to descend and punch the workpiece. During the descent of the upper die 1, the pressure block 5 moves synchronously. As the pressure block 5 moves, it simultaneously drives the second wedge block 6 downwards. Since the second wedge block 6 and the first wedge block 4 are in inclined contact, and the first wedge block 4 is slidably connected and can move horizontally, the downward movement of the second wedge block 6 will compress the first wedge block 4, forcing it to move horizontally. When the first wedge block 4 moves, it will compress the first nitrogen spring 11 against the inner wall of the mounting frame 3. Simultaneously, since the first wedge block 4 and the third wedge block 7 are also in inclined contact, and the third wedge block 7 is also slidably connected and restricted to vertical movement, the first wedge block... 4. During movement, the third wedge block 7 is forced to move vertically, and then the third wedge block 7, in conjunction with the flanging insert 23, performs flanging operation on the edge of the workpiece. At the same time, when the flanging angle needs to be adjusted, the threaded rod 19 can be rotated by adjusting the knob 20. Since the fourth wedge block 18 is slidably connected inside the embedded groove 12 and threaded on the outer surface of the threaded rod 19, the rotation of the threaded rod 19 will synchronously drive the fourth wedge block 18 to move horizontally. Then, the inclined surface of the fourth wedge block 18 will press the adjusting block 13 to move. When the adjusting block 13 moves, it will synchronously drive the contact plate 16 to move, thereby adjusting the contact time between the second wedge block 6 and the first wedge block 4, thus adjusting the final height of the third wedge block 7 and thus adjusting the flanging angle.
[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
