Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model relates to an extrusion forming device for automotive stamping parts, comprising a base 1; two support plates 2 and an operating table 21 are symmetrically fixed on the upper surface of the base 1; a horizontal plate 3 is fixedly connected to the top of the two support plates 2; a stamping assembly is fixedly mounted on the upper surface of the horizontal plate 3, the stamping assembly including a stamping cylinder 4; an upper die 5 connected to the stamping cylinder 4 is snapped onto the lower surface of the horizontal plate 3; a punch 6 is fixedly connected inside the upper die 5; a feeding assembly for use with the stamping assembly is fixedly mounted on the upper surface of the operating table 21, the feeding assembly including a lower die 11; and a lower die 12... The die 11 has a slidable stamping body 17 inside. The outer wall of the upper die 5 is fixedly provided with a protrusion 7. The outer wall of the protrusion 7 is rotatably provided with a connecting rod 10 that works with the punch 6. A reset assembly 20 is fixedly connected between the connecting rod 10 and the upper die 5. The end of the connecting rod 10 is rotatably connected with a roller 8 that works with the trapezoidal block 13. The outer wall of the lower die 11 is fixedly connected with a trapezoidal block 13 that works with the connecting rod 10. The lower die 11 has a limiting groove 12 inside that works with the stamping body 17. The lower die 11 also has a blanking hole 19 inside.

[0025] First, the stamping body 17 is passed through the limiting groove 12 inside the lower die 11 to limit the stamping body 17. Then, an external power source is connected to start the stamping cylinder 4, which drives the upper die 5 and the punch 6 inside the upper die 5 to descend, drilling a hole on the surface of the stamping body 17. After drilling one hole, the stamping body 17 is moved to the vicinity of the connecting rod 10, allowing the connecting rod 10 to pass through the hole on the surface of the stamping body 17. When the punch 6 descends again, it further limits the stamping body 17. 7. During drilling, the roller 8 at the bottom of the connecting rod 10 first contacts the trapezoidal block 13 on one side of the lower die 11. Under the guidance of the inclined surface of the trapezoidal block 13, the connecting rod 10 rotates at a certain angle to cooperate with the hole on the surface of the stamping body 17 and push the stamping body 17 to move. At this time, the stamping cylinder 4 drives the upper die 5 and the punch 6 inside the upper die 5 to rise. With the cooperation of the reset component 20, the connecting rod 10 retracts. The reset component 20 specifically refers to the spring. Repeat the above steps to achieve automatic feeding and drilling.

[0026] Please see Figure 1 and Figure 2 A limiting block 14 for use with the stamping body 17 is fixedly connected to the upper surface of the operating table 21. A pressure plate 16 is slidably connected inside the limiting block 14, and a screw 15 for use with the pressure plate 16 is threadedly connected to the top of the limiting block 14.

[0027] The stamped part body 17 is passed through the slot inside the limiting block 14. The rotating screw 15 drives the pressure plate 16 to press down. The screw 15 and the pressure plate 16 are connected together. Multiple one-way shafts are installed at the bottom of the pressure plate 16 (not shown in the figure). The one-way shafts contact the surface of the stamped part body 17 and press down to limit it. When the stamped part body 17 moves, the one-way shafts rotate normally. When the stamping cylinder 4 drives the upper die 5 and the punch 6 inside the upper die 5 to rise, the connecting rod 10 on the outer wall of the upper die 5 retracts at a certain angle under the pull of the reset assembly 20 and contacts the hole on the surface of the stamped part body 17. At this time, the one-way shafts cannot rotate, so that the friction force of the stamped part body 17 itself is greater than the retraction force of the reset assembly 20. Therefore, when the connecting rod 10 retracts and contacts the surface of the stamped part body 17, it will not cause the stamped part body 17 to move.

[0028] Please see Figure 1 The bottom of the operating table 21 is slidably connected to a collection box 18 that is used in conjunction with the material drop hole 19.

[0029] By setting a collection box 18 at the bottom of the operating table 21, the material falling from the drop hole 19 enters the collection box 18, making it convenient for workers to collect and process it uniformly.

[0030] The operation process of this embodiment is as follows: First, the stamping body 17 is passed through the limiting groove 12 inside the lower die 11 to limit the stamping body 17. Then, the external power supply is connected to start the stamping cylinder 4, which drives the upper die 5 and the punch 6 inside the upper die 5 to descend and drill a hole on the surface of the stamping body 17. After the stamping body 17 has drilled a hole, it is moved to the vicinity of the connecting rod 10 so that the connecting rod 10 can pass through the hole on the surface of the stamping body 17. When the punch 6 descends again to drill a hole in the stamping body 17, the roller 8 at the bottom of the connecting rod 10 first contacts the trapezoidal block 13 on one side of the lower die 11. Under the guidance of the inclined surface of the trapezoidal block 13, the connecting rod 10 is rotated at a certain angle to cooperate with the hole on the surface of the stamping body 17 and push the stamping body 17 to move. At this time, the stamping cylinder 4 drives the upper die 5 and the punch 6 inside the upper die 5 to rise. With the cooperation of the reset component 20, the connecting rod 10 is moved to move the upper die 5. The connecting rod 10 retracts, and the reset component 20 refers specifically to the spring. The above steps are repeated to achieve automatic feeding and punching of the stamped part. The stamped part body 17 passes through the slot inside the limiting block 14. The rotating screw 15 drives the pressure plate 16 to press down. The screw 15 and the pressure plate 16 are connected together. Multiple one-way shafts are installed at the bottom of the pressure plate 16 (not shown in the figure). The one-way shafts contact the surface of the stamped part body 17 and press down to limit it. When the stamped part body 17 moves, the one-way shafts rotate normally. When the stamping cylinder 4 drives the upper die 5 and the punch 6 inside the upper die 5 to rise, the connecting rod 10 on the outer wall of the upper die 5 retracts at a certain angle under the pull of the reset component 20 and contacts the hole on the surface of the stamped part body 17. At this time, the one-way shaft cannot rotate, so that the friction force of the stamped part body 17 itself is greater than the retraction force of the reset component 20. Therefore, when the connecting rod 10 retracts and contacts the surface of the stamped part body 17, it will not cause the stamped part body 17 to move.
