Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 7 The present invention provides a technical solution: Example 1: An automated manufacturing equipment for metal stamping parts includes a base 1, on which a pair of symmetrically distributed molds 7 are arranged. The molds 7 are provided with forming grooves 11 and mold holes 10. A telescopic rod 3 for lifting drive is provided in the middle of the pair of molds 7. A middle support platform 4 is provided in the middle of the base 1. The lower end of the mold 7 is pressed onto the middle support platform 4. An ear seat 16 is provided at the end of the mold 7 near the telescopic rod 3. A connecting rod 12 is provided at the end of the telescopic rod 3. One end of the connecting rod 12 is rotatably connected to the ear seat 16. A limiting seat 23 is provided on the middle support platform 4 to support the lower end of the ear seat 16.

[0020] By setting the telescopic rod 3, the adjacent ends of a pair of molds 7 are driven to rise, so that the molds 7 are tilted outward. In the tilted state, it is easy for the waste material on the surface to slide off. By setting the connecting rod 12 and the ear seat 16 to rotate, it is adapted to the telescopic rod 3 to drive the molds 7. The position of the molds 7 after the telescopic rod 3 is reset is limited by the limit seat 23 and the intermediate support platform 4.

[0021] A guide rail 2 is provided on the base 1, and a slide groove 35 is provided in the guide rail 2. A downwardly inclined plate 18 is provided at the end of the mold 7 away from the telescopic rod 3. The lower end of the inclined plate 18 is slidably installed in the slide groove 35. The front and rear side walls of the guide rail 2 are provided with limiting transverse grooves 29. The front and rear ends of the inclined plate 18 are provided with a main shaft 30. A roller 31 is rotatably sleeved on the main shaft 30. The middle groove of the roller 31 is slidably engaged with the limiting transverse groove 29. The end of the main shaft 30 is connected to the end of the pressure strip 20 through a crossbar 19. The end of the slide groove 35 is provided with an arc-shaped limiting groove 17. The end of the inclined plate 18 can be pressed into the limiting groove 17.

[0022] By setting the slide groove 35, roller 31 and limiting transverse groove 29, the sliding position of the inclined plate 18 is limited. The roller 31 is used to slide and engage on the limiting transverse groove 29 to prevent the inclined plate 18 from falling off the guide rail 2 and ensure that the inclined plate 18 slides along the guide rail 2. The limiting groove 17 is set to limit the sliding position of the inclined plate 18. At the same time, the pressing of the inclined plate 18 on the limiting groove 17 improves the support for the outer end of the template 7.

[0023] A stepped hole 25 is provided at the lower end of the die hole 10. A piston lifting column 13 extending into the inner cavity of the die hole 10 is provided in the stepped hole 25. A cylinder 15 is provided at the lower end of the stepped hole 25. The piston at the lower end of the piston lifting column 13 is slidably installed in the cylinder 15. A fixed lower shell 14 with screws is provided in the inner cavity of the lower end of the stepped hole 25. The cylinder 15 is installed on the fixed lower shell 14. A through hole corresponding to the die hole 10 is provided on the fixed lower shell 14. The middle section of the piston lifting column 13 passes through the through hole.

[0024] The piston lifting column 13 is pneumatically lifted and installed by setting cylinder 15, and cylinder 15 is fixedly installed by using fixed lower shell 14.

[0025] An air bladder 21 is provided on the side of the guide rail 2 near the cylinder 15. The air bladder 21 is connected to the lower end cavity of the cylinder 15 through an air pipe 28. A pressure strip 20 is connected to the inclined plate 18, which slides along the slide groove 35 and is pressed against the end of the air bladder 21. The end of the pressure strip 20 is laterally slidably inserted into the side wall of the guide rail 2. One end of the guide rail 2 is fixed to the base 1 by screws. A baffle 33 is vertically provided in the middle section of the base 1. The other end of the guide rail 2 abuts against the baffle 33. The end opening of the limiting transverse groove 29 abuts against the baffle 33. An air hole 34 is provided on the baffle 33, which corresponds to the position of the end of the air bladder 21. One end of the air pipe 28 is connected to the air bladder 21 through the air hole 34. The inner cavity of the cylinder 15 is provided with a compression inner cavity. The lower end piston of the piston lifting column 13 is slidably installed in the compression inner cavity. The air pipe 28 is connected to the lower end cavity of the compression inner cavity. A material drop groove 32 is provided through the end of the slide groove 35 near the inclined plate 18.

[0026] As the inclined plate 18 slides, the pressure bar 20 slides synchronously, causing the pressure bar 20 to squeeze one end of the airbag 21. This causes the airflow in the airbag 21 to enter the cylinder 15 along the air pipe 28, increasing its internal pressure and driving the piston lifting column 13 to rise. Consequently, the end of the piston lifting column 13 extends to the outside of the die hole 10. During the extension process, the stamping waste that has fallen into the die hole 10 is ejected and slides down the inclined mold 7 surface, achieving the purpose of cleaning the die hole 10. The material drop groove 32 is provided to collect and recycle the falling waste.

[0027] Working principle: First, the mechanical arm places the metal material sheet on the mounting groove 8 of the mold 7. Then, the stamping part is used for stamping and cutting. After the processing is completed, the waste material from cutting and punching falls on the surface of the mold and into the mold hole. At this time, the telescopic rod 3 drives the ends of a pair of symmetrically distributed molds 7 to rise, so that the mold 7 is tilted to the outside. At this time, the waste material on the surface falls down along the inclined surface. During the tilting process, the inclined plate 18 slides along the slide groove 35, so that the raw material falls down along the inclined plate 18 into the material drop groove 32.

[0028] During the tilting process of the mold 7, the pressure bar 20 connected to the inclined plate 18 slides and squeezes the air bag 21, causing the airflow in the air bag 21 to enter the cylinder 15 along the air pipe 28. The internal pressure of the cylinder 15 increases, driving the piston lifting column 13 to rise, thereby causing the upper end of the piston lifting column 13 to extend to the outside of the mold hole 10. During the extension process, the stamping waste that has fallen into the mold hole 10 is pushed out and slides down along the inclined surface of the mold 7, achieving the purpose of cleaning the mold hole 10.

[0029] Example 2: Based on Example 1, ...

[0030] The upper end of the mold 7 is provided with an installation groove 8 for installing hardware raw materials. A guide block 9 is provided at the corner of the installation groove 8, and an inverted conical guide groove is provided on the inner side of the guide block 9.

[0031] By setting a conical guide block 9, the raw materials of the hardware parts are ensured to fall accurately into the mounting groove 8, making the stamping process compatible with automated feeding and improving the accuracy of the processing.

[0032] A ball 24 is provided at the upper end of the piston lifting column 13. A spring 26 is sleeved on the piston lifting column 13 at the position of the upper inner cavity of the stepped hole 25. A wing plate 27 is provided in the middle section of the piston lifting column 13. The upper end of the spring 26 abuts against the upper inner wall of the stepped hole 25, and the lower end of the spring 26 abuts against the upper surface of the wing plate 27.

[0033] By setting the spring 26 and the wing plate 27 together, the piston lifting column 13 is vertically and elastically installed. Thus, when the mold 7 is tilted, the piston lifting column 13 presses against the spring 26. After the mold 7 is reset, under the reset force of the spring 26, the piston lifting column 13 is quickly retracted into the mold hole 10, ensuring the continuous operation of automated stamping.
