During the stamping process, the metal material will be subjected to the pressure and deformation force of the die, thereby producing plastic deformation and finally forming into the required round tube shape parts.

[0003] The existing titanium alloy round tube stamping dies still have some shortcomings in actual use:

[0004] Under the existing technology, when processing various types of metal round tubes, the roundness of titanium alloy round tubes produced by pressing is not good, and the accuracy, quality and production efficiency are low. Utility Model Content

[0009] In a possible design, a guide surface is provided on the top of the clamping block, which can support the aluminum alloy and assist in bending the aluminum alloy, pushing the two clamping blocks away from each other. An impact surface is provided on the bottom of the clamping block, which can further push and stamp the aluminum alloy.

[0010] In a possible design, three connecting plates are fixedly connected to the bottom of the mounting plate, and the second stamping block is fixedly connected to the bottom of the connecting plate, wherein the bottoms of two connecting plates are fixedly connected to the first stamping block and are located on both sides of the second stamping block.

[0011] In a possible design, a long slope is provided on the sides of the two first stamping blocks that are close to each other, a short slope is provided on the sides of the two first stamping blocks that are away from each other, and the bottom of the first stamping block is flush with the center of the second stamping block.

The two clamping blocks are brought close to each other through the elastic force of four springs, thereby supporting the titanium alloy, and the spring is contracted by pressing the titanium alloy downward through the second stamping block. The two clamping blocks move away from each other. As the two clamping blocks move away from each other, the titanium alloy bends and descends with the clamping blocks and gradually bends into the arc groove.

[0016] In the utility model, the structure design of the mold is reasonable and the operation is simple, the operation difficulty and labor intensity are reduced, and the work efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS
