[0005] In order to solve the above technical problems at least to a certain extent, the utility model provides a flange blank forging clamping device.

[0006] The purpose and effect of the flange blank forging clamping device of the utility model are achieved by the following specific technical means:

[0007] A flange blank forging clamping device comprises a base; the top middle position of the base is fixedly connected to the bottom middle position of a support platform, the top front middle position of the base is fixedly connected to the bottom position of an extension plate, the extension plate is located at the front end position of the support platform, the top outer position of the support platform is fixedly connected to a limiting frame, the outer position of the limiting frame is provided with five strip slide grooves, and each strip slide groove is slidably connected with a displacement member, the five displacement members are distributed in a ring shape, and a placement groove is provided at the top middle position of the support platform.

[0008] According to one embodiment of the utility model, the middle position of the displacement member at the front end is fixedly connected to the rear end position of the connecting member, and the upper inner positions of the five displacement members are fixedly connected with a clamping foot, the five clamping feet are distributed in a ring shape, and the five clamping feet are respectively located at the upper outer positions of the placement groove of the support platform.

[0009] According to an embodiment of the utility model, a threaded rod is rotatably connected to the middle position above the front end of the extension plate, and a handle is provided at the front end of the threaded rod.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By cooperating the threaded rod with the threaded hole of the connecting piece, the threaded rod is adjusted to the position of the threaded hole of the connecting piece. When the connecting piece moves to the rearward position, the frontmost displacement piece is driven to slide inward in the strip groove of the limit frame. At this time, since the displacement piece is located in the arc groove of the transmission platform, the transmission platform will rotate. At this time, the other four displacement pieces located in the arc groove of the transmission platform will move synchronously, and the distance between the five displacement pieces will be reduced until the flange blank of the support platform placement groove is clamped and fixed at the inner position of the five clamping feet.

[0014] When the transmission table is rotating, the five displacement parts are ensured to move synchronously. When the flange blank contacts any clamping foot individually, the contacting clamping foot will generate thrust until the inner sides of the five clamping feet are in contact with the flange blank, and the flange blank is centered above the support table placement slot to avoid the flange blank being offset during processing and causing waste.

[0027] Among them, the middle position of the frontmost displacement member 2 is fixedly connected to the rear end position of the connecting member 105, and the upper inner positions of the five displacement members 2 are fixedly connected with a clamping foot 201. The five clamping feet 201 are distributed in a ring shape, and the five clamping feet 201 are respectively located at the upper outer positions of the placement groove of the support platform 101.

[0028] Among them, a threaded rod 104 is rotatably connected to the middle position above the front end of the extension plate 103, a handle is set at the front end of the threaded rod 104, a threaded hole is opened at the front end position of the connecting piece 105, and the rear end position of the threaded rod 104 is rotatably connected in the threaded hole of the connecting piece 105, the limit frame 102 is located directly above the transmission platform 3, and five arc grooves are opened on the outer side of the transmission platform 3, and the five displacement members 2 are all located in the five arc grooves of the transmission platform 3.
