[0026] Example

[0027] Reference Figures 1 to 5 This embodiment provides a high-strength flange forging die, including a base 100, a lower die 200 and a support mechanism 300, wherein a portion of the support mechanism 300 is installed inside the base 100, and the other portion is arranged above the outside of the base 100, for limiting support of the lower die 200.

[0028] Specifically, a support plate 101 is fixedly installed at the center of the top of the base 100, and movable grooves 102 are symmetrically opened on the left and right sides inside the base 100. A forging groove 201 is opened inside the lower mold 200, and a circular through groove 202 is opened at the bottom of the forging groove 201. Arc grooves 203 are symmetrically opened on the left and right sides of the bottom end of the lower mold 200, and the outer sides of the two arc grooves 203 are connected with telescopic grooves 204. Press plates 205 are symmetrically fixedly installed on the outer side walls of the left and right ends of the lower mold 200. The supporting mechanism 300 includes an arc support plate 301 slidably connected in the two movable grooves 102, and the top ends of the two arc support plates 301 extend into the two arc grooves 203 respectively and abut against the inner top walls of the two arc grooves 203. Push blocks 302 are arranged on the inner sides of the two arc support plates 301, and the adjustment components 303 are transmission-connected at the centers of the two push blocks 302.

[0029] Furthermore, the adjustment component 303 includes a knob 303a arranged on the outside of the base 100, the right end of the knob 303a is fixedly connected to the rotating rod 303b, the right end of the rotating rod 303b passes through the outer wall of the base 100 and extends to the inside thereof and is fixedly connected to the first threaded rod 303c, the right end of the first threaded rod 303c is fixedly connected to the rotating shaft 303d, the right end of the rotating shaft 303d is fixedly connected to the second threaded rod 303e, the first threaded rod 303c is arranged in the right side moving groove 102, the second threaded rod 303e is arranged in the left side moving groove 102, and the external threads of the first threaded rod 303c and the second threaded rod 303e are arranged in opposite directions, the two push blocks 302 are respectively threadedly connected to the outer surfaces of the first threaded rod 303c and the second threaded rod 303e, and the outer sides of the two push blocks 302 are respectively fixedly connected to the inner walls of the two arc-shaped support plates 301.

[0030] In the adjustment component 303, the knob 303a is arranged on the outside of the base 100, which can be convenient for the staff to rotate. When the staff rotates the knob 303a in the forward direction, the knob 303a can drive the first threaded rod 303c to rotate through the rotating rod 303b, and the first threaded rod 303c can drive the second threaded rod 303e to rotate through the rotating shaft 303d. Because the external threads of the first threaded rod 303c and the second threaded rod 303e are arranged in opposite directions, when the first threaded rod 303c and the second threaded rod 303e rotate forward at the same time, the two push blocks 302 can be driven to move horizontally in opposite directions, and the two push blocks 302 can drive the two arc-shaped support plates 301 to move toward the outside of the two movable grooves 102. Similarly, when the staff rotates the knob 303a in the reverse direction, the two push blocks 302 can drive the two arc-shaped support plates 301 to move relative to each other horizontally.

[0031] Preferably, a bearing 304 is installed at the connection between the rotating shaft 303d and the inner wall of the base 100, and the rotating shaft 303d is rotatably connected to the middle part of the base 100 through the bearing 304. The setting of the bearing 304 can play a role of limiting support for the rotating shaft 303d. At the same time, due to the characteristics of the bearing 304 itself, the rotating shaft 303d can rotate more smoothly to avoid jamming and affect the operation of the adjustment component 303.

[0032] Preferably, the top of the support plate 101 is arranged in the circular through groove 202, and the upper surface of the support plate 101 is on the same horizontal line with the inner top wall of the forging groove 201, ensuring that the opening of the circular through groove 202 will not affect the subsequent processing of the flange. At the same time, the support plate 101 in the circular through groove 202 can play a role of limiting support for the flange placed inside the forging groove 201, and through the opening of the circular through groove 202, it is ensured that the lower mold 200 will not be blocked by the support plate 101 when it moves vertically downward.

[0033] In the above structure, the shapes of the two arc-shaped support plates 301 are adapted to the two arc-shaped grooves 203 and the telescopic grooves 204 opened at the bottom of the lower mold 200, ensuring that the two arc-shaped support plates 301 can be inserted into the two arc-shaped grooves 203, and when the upper surfaces of the two arc-shaped support plates 301 are against the inner top walls of the two arc-shaped grooves 203, they can play a role of limiting support for the lower mold 200, providing necessary conditions for the subsequent flange forging work, and when the flange needs to be taken out after forging, the staff can control the two push blocks 302 to move horizontally in opposite directions by adjusting the assembly 303, and the two push blocks 302 can push the two arc-shaped support plates 301 to move horizontally in opposite directions, and when the two arc-shaped support plates 301 move into the two telescopic grooves 204, there is no shielding of the inner top walls of the arc-shaped grooves 203 (such as Figure 2 As shown, the vertical height of the telescopic groove 204 is greater than that of the arc groove 203). At this time, the staff can move the lower mold 200 vertically downward by pressing the pressure plates 205 on both sides, and the support plate 101 inside the lower mold 200 can continue to play a role in limiting the support of the formed flange, thereby realizing the separation of the flange and the lower mold 200. The staff can smoothly remove the flange. The structural design is reasonable, simple and convenient to operate, and effectively improves work efficiency.
