Fig. 1 is a schematic structural diagram of a stamping die 100 for automatic material hooking and feeding according to an embodiment of the present utility model, fig. 2 is a cross-sectional view of the stamping die 100 for automatic material hooking and feeding according to an embodiment of the present utility model, and fig. 3 is a schematic structural diagram of a stamping material 900 according to an embodiment of the present utility model. Referring to fig. 1 to 3, a stamping die 100 for automatic material hooking and feeding according to the present utility model includes a lower die 10, an upper die 20, a material pulling seat 30, a driving assembly 40 and a material blocking assembly 50.

The lower die 10 is used for placing a punching material 900 having a plurality of material holes 901, the lower die 10 is formed with a chute 101, and the chute 101 has an upstream end 1011 and a downstream end 1012. The upper die 20 is provided above the lower die 10 so as to be movable up and down for pressing the pressing material 900. The material blocking assembly 50 is disposed on the upper die 20, and partially extends out of the lower surface of the upper die 20.

The material pulling seat 30 is slidably arranged on the chute 101, and the material pulling seat 30 is provided with a material pulling hook 31 which is suitable for being inserted into the material hole 901. And the upper die 20 is moved up away from the punched material 900, the draw bench 30 slides away from the upstream end 1011, so that the draw hook 31 inserted into the orifice 901 draws the punched material 900 away from the upstream end 1011. When the upper die 20 moves down to punch the punched material 900, the material pulling seat 30 slides close to the upstream end 1011, and the material blocking assembly 50 prevents the punched material 900 from moving towards the direction close to the upstream end 1011, so that the material pulling hook 31 is switched into the adjacent another material hole 901, and when the material pulling seat 30 slides back and forth for a plurality of times, the material pulling hook 31 can pull the punched material 900 to move towards the direction far from the upstream end 1011 for a plurality of steps.

That is, after the upper die 20 punches the punched material 900 once, the drawing seat 30 slides away from the upstream end 1011 in the stroke of the upper die 20 moving away from the die, so that the drawing hook 31 inserted into the hole 901 draws the punched material 900 to move away from the upstream end 1011, thereby achieving the purpose of driving the punched material 900 to move away from the upstream end 1011 by one step. After the upper die 20 is opened, the upper die 20 moves down again to punch the punched material 900, and the pulling hook 31 slides close to the upstream end 1011, and the punched material 900 does not slide close to the upstream end 1011 along with the pulling hook 31 due to the blocking of the punched material 900 by the blocking assembly 50, and the pulling hook 31 is separated from the hole 901 in the last punching stroke and inserted into the adjacent other hole 901, so that the pulling hook 31 can drive the punched material 900 to move one step further away from the upstream end 1011 when the upper die 20 moves up again. In this way, after the upper die 20 punches the punched material 900 a plurality of times and the material pulling seat 30 slides reciprocally a plurality of times, the material pulling hook 31 on the material pulling seat 30 can pull the punched material 900 to move a plurality of steps along the direction from the upstream end 1011 to the downstream end 1012 until the upper die 20 completely punches the punched material 900.

The driving assembly 40 is used for driving the material pulling seat 30 to slide repeatedly and reciprocally. Thus, since the punch material 900 can be moved multiple steps in the direction from the upstream end 1011 to the downstream end 1012 in the process of punching the punch material 900 multiple times by the upper die 20, the punch material 900 can be continuously conveyed downstream. Therefore, the stamping die 100 for automatic material hooking and feeding not only can automatically convey the stamping material 900 downstream in the continuous stamping process, but also does not need to additionally arrange an automatic feeder, and has simple structure and low cost.

Fig. 4 is a schematic structural view of the pulling hook 31 according to the embodiment of the present utility model, referring to fig. 2 and 4, a pulling inclined surface 311 extending from bottom to top is formed at the top end of the pulling hook 31 along the direction from the upstream end 1011 to the downstream end 1012. In this way, when the pulling hook 31 slides close to the upstream end 1011, it is easy to withdraw from the previous hole 901 and switch to the adjacent hole 901, so that the switching is convenient and smooth.

Fig. 5 is an exploded view of the automatic hooking and feeding stamping die 100 according to the embodiment of the present utility model, referring to fig. 1, 2 and 5, the driving assembly 40 includes a sliding shaft 41, a pushing member 42 and an elastic restoring member 43.

The sliding shaft 41 is connected with the material pulling seat 30, and two ends of the sliding shaft extend out of the lower die 10. When the upper die 20 is connected to the pushing member 42 and the upper die 20 drives the pushing member 42 to move downward, the pushing member 42 pushes two ends of the sliding shaft 41 to slide close to the upstream end 1011, so as to drive the material pulling seat 30 to slide close to the upstream end 1011. The elastic restoring member 43 is disposed between the lower die 10 and the pulling seat 30, and is used for driving the pulling seat 30 to slide away from the upstream end 1011.

That is, after the upper die 20 punches the punched material 900 once, in the process of removing the die from the upper die 20, the upper die 20 drives the pushing member 42 to move upwards, so that the compressed elastic force of the elastic restoring member 43 drives the material pulling seat 30 to slide away from the upstream end 1011, so that the driving assembly 40 can drive the material pulling seat 30 to slide away from the upstream end 1011 when the upper die 20 moves upwards. In the process of re-stamping the stamping material 900 by the upper die 20, the upper die 20 moves down to drive the pushing member 42 to move down, so that the pushing member 42 pushes the material pulling seat 30 to slide close to the upstream end 1011, so that when the upper die 20 moves down, the driving assembly 40 can drive the material pulling seat 30 to slide close to the upstream end 1011, and in this process, the elastic reset member 43 is compressed again, the material pulling hook 31 is switched into the adjacent other material hole 901, so that when the upper die 20 drives the pushing member 42 to move up again after stamping, the material pulling hook 31 will pull the stamping material 900 to slide away from the upstream end 1011 again under the elastic force of the elastic reset member 43.

Referring to fig. 1 and 5, the pushing member 42 includes two pushing blocks 421, each of the pushing blocks 421 is formed with a pushing surface 4211 adapted to be disposed opposite to an end of the sliding shaft 41, and the pushing surface 4211 extends from top to bottom in a direction from the upstream end 1011 to the downstream end 1012. In this way, the pushing member 42 facilitates smooth pushing of the sliding shaft 41.

Further, referring to fig. 5, each end of the sliding shaft 41 is sleeved with a rotatable wheel 411, so that when the pushing block 421 pushes the sliding shaft 41, the wheel 411 rotates, thereby reducing friction and loss of the sliding shaft 41.

According to some preferred embodiments of the present utility model, referring to fig. 2, the blocking assembly 50 includes a blocking hook 51, and the blocking hook 51 protrudes from the lower surface of the upper mold 20 and is adapted to be inserted into the hole 901. In this way, when the pulling hook 31 on the pulling seat 30 slides along with the pulling seat 30 to approach the upstream end 1011, the blocking hook 51 on the upper die 20 is inserted into the hole 901, and the punched material 900 is kept still, so that the pulling hook 31 can be withdrawn from the previous hole 901 and switched to the adjacent hole 901.

Further, fig. 6 is a schematic structural view of the stop hook 51 according to the embodiment of the present utility model, and referring to fig. 6, an insertion portion 511 with an outer diameter gradually decreasing from top to bottom is formed at the bottom of the stop hook 51. In this way, the blocking hook 51 is conveniently inserted into the hole 901.

Further, referring to fig. 2, the material blocking assembly 50 further includes a mounting base 52 and an elastic member 53. The mounting base 52 is provided on the upper die 20. The elastic piece 53 is respectively connected with the mounting seat 52 and the blocking hook 51, so that the blocking hook 51 is pressed against the lower die 10 after the blocking hook 51 passes through the material hole 901. In this way, the elastic member 53 may have an effect of preventing the stop hook 51 from being separated from the hole 901, so as to ensure that the stop hook 51 always has a stop function.

According to some preferred embodiments of the present utility model, referring to fig. 2 and 5, a placement seat 60 is disposed above the lower die 10, and a placement groove 601 extending in the same direction as the chute 101 is formed in the placement seat 60 for placing the punching material 900. Thus, when the draw hook 31 pulls the punching material 900, the punching material 900 slides in the placement groove 601, so that the punching material 900 can slide smoothly near or far from the upstream end 1011 and the downstream end 1012.

It will be appreciated by persons skilled in the art that the embodiments of the utility model described above and shown in the drawings are by way of example only and are not limiting. The advantages of the present utility model have been fully and effectively realized.
