Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 1 to 5, the present invention discloses a die for blanking a tube, including:

first mould 1, first mould 1 is used for offering the keyway to tubular product, and first mould 1 includes:

the fixed block 11 is fixed on the workbench;

the first upper die holder 12 is connected to the stamping device;

the first lower die holder 13 is vertically opposite to the first upper die holder 12, the first lower die holder 13 is fixed on the fixed block 11 and is emptied from the workbench, a vertically opposite placing port 2 and a chip removal port are formed in the first lower die holder 13, the placing port 2 is used for a pipe to penetrate, a hollow chip removal rod core 3 is fixedly sleeved on the periphery of the chip removal port, and the chip removal rod core 3 extends towards the placing port 2;

and the second die 4 is used for punching the pipe.

When the keyway is seted up to needs on tubular product, penetrate this place mouthful 2 with tubular product one end in, make first upper die base 12 and first die holder 13 compound die each other afterwards, at the in-process of compound die, chip removal core 3 can penetrate in the tubular product, the sweeps that produce this moment can directly discharge from first mould 1 through hollow chip removal core 3, thereby just can discharge the sweeps when the blanking, machining efficiency has been improved and has been reduced, and need not the frequent sweeps on the mould of workman and clear up, the reduction has increaseed workman's intensity of labour, and separate spaciously between first die holder 13 and the workstation through fixed block 11, thereby the workman is convenient for clear up the sweeps of discharging the mould.

The first die 1 and the second die 4 are respectively and independently arranged to respectively finish the machining of the key slot and the punched hole of the tube, and the machining sequence is not fixed.

The first lower die holder 13 comprises an upper die holder plate 131, a lower die holder plate 132 and a guide rod 133, the upper die holder plate 131 and the lower die holder plate 132 are respectively sleeved at two ends of the guide rod 133, the placing port 2 is arranged on the upper die holder plate 131, and the chip removal port is arranged on the lower die holder plate 132.

By providing the guide rod 133, the upper die base plate 131 and the lower die base plate 132 of the first lower die holder 13 are more accurately clamped in the process of clamping the first upper die holder 12 and the first lower die holder 13.

Still include bracing piece 5, bracing piece 5 sets up between last mold base board 131 and lower mold base board 132, and the cover is equipped with spring 6 on bracing piece 5, and spring 6 both ends butt respectively is in last mold base board 131 bottom and lower mold base board 132 top.

Through setting up spring 6, after first upper die base 12 and first die holder 13 compound die, utilize spring 6 can be convenient for first upper die base 12 and the die sinking of first die holder 13 because of the reaction force that takes place the production of deformation to be convenient for take out the tubular product after seting up the keyway.
