However, in actual use, during long-term stamping work, the stamping die will be worn, which may result in burrs on the stamped workpiece. The workers need to perform deburring on the workpiece, which is a cumbersome process. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes an automatic deburring stamping device. When the workpiece falls into the interior of the grinding belt through the forming groove on the stamping die, the inner sidewall of the grinding belt can fit in close contact with the surface of the workpiece. By moving the workpiece inside the grinding belt, the grinding belt grinds away the burrs on the sidewall of the workpiece, thus achieving the effect of automatic deburring of the workpiece.

[0006] The technical solution to achieve the purpose of this utility model is as follows: an automatic deburring stamping device, including a processing table, multiple support legs fixedly installed on the bottom wall of the processing table, a fixed frame fixedly installed on the side wall of the processing table, a stamping cylinder fixedly installed on the top wall of the fixed frame, a stamping plate fixedly installed on the top wall of the stamping cylinder, a stamping die fixedly installed at the output end of the stamping plate, and a stamping die fixedly installed on the top wall of the processing table by bolts. A discharge groove is opened on the top wall of the processing table, and a grinding component located inside the discharge groove is provided at the bottom of the stamping die. The grinding component includes:

[0007] Multiple positioning rods are fixedly installed on the bottom wall of the stamping die. The positioning rods have an inner rod inside, which is also fixedly installed on the bottom wall of the stamping die.

[0008] Multiple outer rods are fixedly installed on the bottom wall of the stamping die;

[0009] A grinding belt is provided at the bottom of the stamping die. The grinding belt is located between the positioning rod and the inner rod, and the side wall of the grinding belt is in contact with the side wall of the outer rod. The bottom end of the inner side wall of the grinding belt is aligned with the inner side wall of the forming groove on the stamping die under the restriction of the positioning rod and the outer rod.

[0010] In some embodiments, multiple positioning rods are located at the inner corner of the forming groove at the bottom of the stamping die, and multiple outer rods are located at the outer corner of the forming groove at the bottom of the stamping die. The bottom end of the positioning rod is inclined towards the inside of the stamping die.

[0011] In some embodiments, a positioning component is provided at the bottom of the processing table, the positioning component including;

[0012] A positioning plate is slidably installed at the bottom of the discharge trough, and the side wall of the positioning plate is inclined.

[0013] A positioning frame is fixedly installed on the bottom wall of the processing table. A sliding rod slides through the inside of the positioning frame, and the top wall of the sliding rod is fixedly connected to the bottom wall of the positioning plate.

[0014] In some embodiments, a return spring is fitted on the side wall of the sliding rod, and the return spring is located between the positioning plate and the positioning frame.

[0015] In some embodiments, a top rod is fixedly installed at the top center of the positioning plate.

[0016] In some embodiments, a hemispherical ball is fixedly installed on the top wall of the top rod.

[0017] Compared with the prior art, the significant advantages of this utility model are:

[0018] Firstly, this utility model, by setting the grinding component at the bottom of the stamping die, aligns the inner wall of the grinding belt with the inner wall of the forming groove on the stamping die. When the workpiece falls into the interior of the grinding belt through the forming groove on the stamping die, and the bottom end of the grinding belt is aligned with the inner wall of the forming groove on the stamping die, the inner wall of the grinding belt can fit against the surface of the workpiece. By moving the workpiece inside the grinding belt, the grinding belt grinds away the burrs on the side wall of the workpiece, achieving the effect of automatic deburring of the workpiece; thus solving the problem of the existing need for additional deburring work on the workpiece.

[0019] Secondly, this utility model utilizes the elasticity of a return spring to push the positioning plate upwards into the discharge trough, allowing the positioning plate to intercept the workpieces inside the grinding belt. Since the grinding belt continuously stores workpieces, the positioning plate moves downwards, and the workpieces at the bottom are discharged outwards along the side wall of the positioning plate, achieving an automatic discharge effect. After the bottom workpieces are discharged, the positioning plate moves upwards under the influence of the return spring, causing the workpieces at the top of the positioning plate to move upwards synchronously, resulting in repeated friction between the workpieces and the side wall of the grinding belt, thus improving the deburring effect.

[0027] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 protection scope of the present invention.

[0028] This utility model provides an improved automatic deburring stamping device. The technical solution of this utility model is as follows:

[0029] like Figures 1-4 As shown, an automatic deburring stamping device includes a processing table 1. Multiple support legs 2 are fixedly installed on the bottom wall of the processing table 1. A fixing frame 3 is fixedly installed on the side wall of the processing table 1. A stamping cylinder 4 is fixedly installed on the top wall of the fixing frame 3. A stamping plate 5 is fixedly installed on the top wall of the stamping cylinder 4. A stamping die 6 is fixedly installed at the output end of the stamping plate 5. The stamping die 6 is bolted to the top wall of the processing table 1. The stamping die 6 is aligned with the stamping plate 5. The top wall of the stamping die 6 has a discharge groove 7 aligned with the stamping die 6. The bottom of the stamping die 6 has a grinding assembly located inside the discharge groove 7. The grinding assembly includes multiple positioning rods 8, multiple outer rods 10, and a grinding belt 11. Multiple positioning rods 8 are fixedly installed on the bottom wall of the stamping die 6, located at the inner corner of the forming groove at the bottom of the stamping die 6. Each positioning rod 8 has an inner rod 9 inside, which is also fixedly installed on the bottom wall of the stamping die 6. The bottom end of the positioning rod 8 is angled towards the stamping die. The die 6 is inclined with its interior close together; multiple outer rods 10 are fixedly installed on the bottom wall of the die 6, and the multiple outer rods 10 are located at the external corners of the forming groove at the bottom of the die 6; a grinding belt 11 is set at the bottom of the die 6, the grinding belt 11 is located between the positioning rod 8 and the inner rod 9, and the side wall of the grinding belt 11 is in contact with the side wall of the outer rod 10, and the bottom end of the inner side wall of the grinding belt 11 is aligned with the inner side wall of the forming groove on the die 6 under the restriction of the positioning rod 8 and the outer rod 10; by setting the grinding assembly... The grinding belt 11 is placed at the bottom of the stamping die 6. The inner wall of the grinding belt 11 is aligned with the inner wall of the forming groove on the stamping die 6. When the workpiece falls into the interior of the grinding belt 11 through the forming groove on the stamping die 6, and the bottom end of the grinding belt 11 is aligned with the inner wall of the forming groove on the stamping die 6, the inner wall of the grinding belt 11 can fit against the surface of the workpiece. As the workpiece moves inside the grinding belt 11, the grinding belt 11 grinds away the burrs on the side wall of the workpiece, thus preventing the workpiece surface from having burrs.

[0030] like Figures 1-3As shown, in this embodiment, a positioning assembly is provided at the bottom of the processing table 1. The positioning assembly includes a positioning plate 12 and a positioning frame 14. The positioning plate 12 is slidably installed at the bottom of the discharge trough 7, and the side wall of the positioning plate 12 is inclined. The positioning frame 14 is fixedly installed on the bottom wall of the processing table 1. A sliding rod 16 slides through the inside of the positioning frame 14. The top wall of the sliding rod 16 is fixedly connected to the bottom wall of the positioning plate 12. A return spring 15 is sleeved on the side wall of the sliding rod 16. The return spring 15 is located between the positioning plate 12 and the positioning frame 14. By utilizing the return spring 15... The elastically driven positioning plate 12 moves upward and enters the discharge groove 7, causing the positioning plate 12 to intercept the workpiece inside the grinding belt 11. Since the grinding belt 11 continuously stores workpieces, the positioning plate 12 moves downward, and the workpiece at the bottom is discharged outward along the side wall of the positioning plate 12, achieving the effect of automatic discharge. After the bottom workpiece is discharged, the positioning plate 12 moves upward under the elastic influence of the return spring 15, causing the workpiece at the top of the positioning plate 12 to move upward synchronously, so that the workpiece and the side wall of the grinding belt 11 are repeatedly rubbed, thereby improving the deburring effect.

[0031] like Figure 3 As shown, in this embodiment, a top rod 13 is fixedly installed at the top center of the positioning plate 12; the height of the positioning plate 12 is increased by the top rod 13, thereby increasing the moving distance of the workpiece inside the grinding belt 11 and further improving the deburring effect; a top ball 17 is fixedly installed on the top wall of the top rod 13, and the top ball 17 is hemispherical; because the hemispherical top ball 17 is located at the top of the top rod 13, when the positioning plate 12 is disengaged from the inside of the discharge groove 7, the workpiece is more likely to tilt, making it easier for the workpiece to be discharged from the inside of the discharge groove 7.

[0032] The specific working method is as follows: By setting the grinding assembly at the bottom of the stamping die 6, the inner wall of the grinding belt 11 is aligned with the inner wall of the forming groove on the stamping die 6. When the workpiece falls into the interior of the grinding belt 11 through the forming groove on the stamping die 6, and the bottom end of the grinding belt 11 is aligned with the inner wall of the forming groove on the stamping die 6, the inner wall of the grinding belt 11 can fit against the surface of the workpiece. By the movement of the workpiece inside the grinding belt 11, the grinding belt 11 grinds away the burrs on the side wall of the workpiece, preventing burrs from appearing on the surface of the workpiece. This is achieved by utilizing the spring of the return spring 15. The positioning plate 12 is pushed upward and enters the discharge groove 7, so that the positioning plate 12 intercepts the workpiece inside the grinding belt 11. Since the grinding belt 11 continuously stores workpieces, the positioning plate 12 moves downward, and the workpiece at the bottom is discharged outward along the side wall of the positioning plate 12, thus achieving the effect of automatic discharge. After the bottom workpiece is discharged, the positioning plate 12 moves upward under the elastic influence of the return spring 15, so that the workpiece at the top of the positioning plate 12 moves upward synchronously, so that the workpiece and the side wall of the grinding belt 11 are repeatedly rubbed, thereby improving the deburring effect.
