Description

Technical Field

[0001] This utility model relates to the field of metal parts stamping technology, specifically a metal parts stamping equipment with automatic feeding function. Background Technology

[0002] Stamping is a forming process that uses a stamping press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces of the desired shape and size. Due to its advantages such as high efficiency, precision, and mass production capability, stamping is widely used in the forming and processing of metal parts.

[0003] According to the description in the patent application (authorization announcement number: CN 220698077 U) of a metal stamping die, "This utility model discloses a metal stamping die, belonging to the field of metal processing technology, including a workbench, with several support rods fixed at its bottom end, a support plate and an L-shaped plate fixed at its top end, and stamping grooves and recesses. A movable plate is provided in the recesses, a first column is fixed to the front end face of the movable plate through a connecting rod, and a push plate is fixed to the side of the top end. Several metal plates are provided at the top end of the support plate, and straight rods are fixed at the four corners of the top end. A telescopic cylinder is fixed to the inner side of the top end of the L-shaped plate, and its telescopic rod is connected to the stamping die. A first round tube is movably connected to the first column. A drive motor is fixed to the front end face of the workbench, and a turntable is connected to its output end. A second column is fixed to the edge of the front end face of the turntable, and a second round tube is movably connected to the second column. The second round tube is connected to the first round tube through a drive rod. Using this die, automatic feeding is possible, resulting in high efficiency and meeting the stamping requirements of enterprises."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This utility model, in its operation, utilizes a combination of a worktable, support plate, and L-shaped plate. A drive motor rotates a turntable, transmitting power via a drive rod to cause a pusher plate to reciprocate, automatically pushing the metal sheet. Simultaneously, a telescopic cylinder drives the stamping die to complete the stamping operation. However, in actual use, after pushing the bottom layer of metal parts, the pusher plate often experiences significant frictional resistance during its return journey due to the direct weight of the stacked upper parts acting on its surface. This leads to jamming and sticking, affecting the continuous feeding rhythm. Furthermore, the conveying process from the feeding mechanism to the stamping die relies on a single track guide, lacking an active centering adjustment mechanism. When the parts themselves have slight dimensional deviations or are affected by vibration during conveying, positional shifts are highly likely. Therefore, an improved metal parts stamping equipment with automatic feeding functionality is needed to solve these problems. Utility Model Content

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Example: Figures 1-6As shown, this utility model provides a technical solution: a metal parts stamping equipment with automatic feeding function, including a workbench 1, a stamping machine 4 is provided on the top of the workbench 1, and a feeding mechanism 3, which includes: a mounting frame 34, which is fixedly installed on the top of the workbench 1, a third synchronous wheel 352 is rotatably mounted on the front of the mounting frame 34, the third synchronous wheel 352 is fixedly installed on the rotating disk 35 through a rotating shaft, a first limiting rod 351 is fixedly installed on the back of the rotating disk 35, a fourth synchronous wheel 354 is driven and installed on the outside of the third synchronous wheel 352 through a second synchronous belt 353, and the fourth synchronous wheel 354 is fixedly installed on the transmission shaft 23; a placement frame 31, which is fixedly installed on the top of the workbench 1, a rotating rod 36 is rotatably mounted on the side of the mounting frame 34 near the rotating disk 35, a limiting groove 361 is opened inside the rotating rod 36, a sliding plate 37 is slidably installed in the inner cavity of the placement frame 31, and the inner cavity extends to the side of the placement frame 31. A second limiting rod 371 is fixedly installed on the front of the sliding plate 37 and assembled inside the limiting groove 361. A push plate 38 is fixedly installed on the top of the sliding plate 37. An opening is opened on the top of the placement rack 31, and the opening communicates with the inner cavity of the placement rack 31. The upper part of the push plate 38 is slidably connected to the opening. A rotating column 381 is rotatably installed inside the push plate 38. A first limiting rod 351 is assembled inside the limiting groove 361. A guide bracket 33 is fixedly installed on the inner side of the placement rack 31. A guide bracket 33 is fixedly installed on the top of the placement rack 31. A limiting frame 32 is installed, and the inner side of the limiting frame 32 is used to stack the metal parts 5 to be stamped. The sliding plate 37 and the push plate 38 are driven to reciprocate through the second limiting rod 371. The push plate 38 can accurately push the bottom metal parts 5, and the rotating column 381 inside it can receive the parts falling from the upper layer when the push plate 38 returns, avoiding jamming and achieving smooth reciprocating motion. This avoids interruption of feeding due to jamming, ensures a continuous and stable feeding rhythm, and greatly improves the reliability of the feeding process.

[0029] Furthermore, such as Figures 2-4As shown, the system also includes a centering mechanism 2, which comprises two symmetrically arranged fixed frames 21. The fixed frames 21 are fixedly installed on the top of the workbench 1. Multiple drive shafts 23 are rotatably arranged inside the two fixed frames 21. A motor 22 is fixedly installed on the front of the fixed frame 21. The output end of the motor 22 is connected to one of the drive shafts 23. A first synchronous pulley 231 is fixedly installed on the back of the drive shaft 23. A second synchronous pulley 233 is installed on the outside of the first synchronous pulley 231 via a first synchronous belt 232. The second synchronous pulley 233 is fixedly installed on the adjacent drive shaft 23. Multiple sets of first synchronous pulleys 231 and second synchronous pulleys 233 are provided, and each set of first synchronous pulleys 231 and second synchronous pulleys 233 is fixedly installed to the end of the corresponding drive shaft 23. The centering mechanism 2 also includes a slide rail 24. A sliding frame 25 is slidably installed on the top of the slide rail 24. A clamping plate 26 is fixedly installed on the top of the sliding frame 25 via a support rod 251. A rotating wheel 261 is rotatably installed on the inner side of the clamping plate 26. The bottom of the sliding frame 25... A first connecting rod 27 is rotatably mounted. A second connecting rod 271 is rotatably mounted at the end of the first connecting rod 27 away from the sliding frame 25. The middle part of the second connecting rod 271 is rotatably mounted on the top of the worktable 1 via a rotating shaft. An electric push rod 28 is fixedly mounted on the top of the worktable 1. The output end of the electric push rod 28 is fixedly mounted to the sliding frame 25. The centering mechanism 2 is set between the feeding mechanism 3 and the stamping machine 4. The slide rail 24, the sliding frame 25, the support rod 251, the clamping plate 26, and the rotating wheel 261 are symmetrically distributed on the drive shaft 2. On both sides below the first link 27, a third link 272 is rotatably mounted at the end of the second link 271 away from the first link 27. The third link 272 is rotatably mounted with another sliding frame 25. By setting the centering mechanism 2 between the feeding mechanism 3 and the stamping machine 4, when the metal part 5 is pushed to the surface of the drive shaft 23, the electric push rod 28 drives the sliding frame 25 to slide along the slide rail 24, causing the clamping plates 26 on both sides to move closer simultaneously. The rotating wheel 261 on the inner side of the clamping plate 26 guides the metal part 5 for centering. The rotating wheel 261 reduces friction with the part, ensuring centering accuracy and avoiding damage to the surface of the part, ensuring that the part is accurately delivered to the bottom of the stamping machine 4, and improving the stability of stamping quality.

[0030] It should be noted that the stamping machine 4 is existing technology. Its working principle is as follows: the power source drives the stamping die to move up and down reciprocatingly. When the metal part 5 is transported to the stamping station, the slide moves the stamping die installed at its bottom down quickly. The pressure between the die and the lower die is used to plastically deform the metal part 5. After the processing is completed, the slide moves up to reset and waits for the next workpiece to enter the station, thus realizing continuous stamping operation. Because this technology is a commonly used technology recognized in the field, it is not described in detail in this application.

[0031] In actual operation, when this device is used, the metal part 5 to be stamped is placed on top of the limit frame 32, the motor 22 is started, and the output end of the motor 22 drives the transmission shaft 23 to rotate. The rotation of the transmission shaft 23 drives the first synchronous pulley 231 on the other side to rotate. The rotation of the first synchronous pulley 231 drives the second synchronous pulley 233 to rotate through the first synchronous belt 232, which in turn drives the remaining transmission shafts 23 to rotate, thus causing the transmission shafts 23 to rotate. When the transmission shafts 23 rotate, they drive the fourth synchronous pulley 354 to rotate. The rotation of the fourth synchronous pulley 354 drives the third synchronous pulley 352 to rotate through the second synchronous belt 353, which in turn drives the rotating disk 35 to rotate. The third synchronous pulley 352 is fixedly mounted on the surface of the rotating disk 35. The wheel 352 moves within the limiting groove 361 inside the rotating rod 36, causing the rotating rod 36 to swing. When the rotating rod 36 swings, the second limiting rod 371 also moves within the limiting groove 361, causing the sliding plate 37 to slide within the sliding groove of the placement frame 31. This causes the push plate 38 to push the bottom layer of the stacked metal parts 5 inside the limiting frame 32, pushing the metal parts 5 along the guide inclined plate 33 to the surface of the drive shaft 23 for conveying. During the pushing process, as the sliding plate 37 returns, the top layer of metal parts 5 falls onto the top of the rotating column 381 inside the push plate 38, allowing the push plate 38 to return smoothly and perform a reciprocating pushing operation.

[0032] When the metal part 5 is pushed onto the surface of the drive shaft 23, the electric push rod 28 is activated. The output end of the electric push rod 28 drives the sliding frame 25 to slide on the outside of the slide rail 24, thereby causing the rotating wheel 261, which is rotatably mounted on the inside of the clamping plate 26, to perform a centering and guiding operation on the metal part 5, and transport it into the stamping machine 4 for stamping operation.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
