Technical Field

[0001] This utility model relates to the field of sheet metal stamping, and in particular to a stamping equipment for sheet metal processing. Background Technology

[0002] In motorcycle manufacturing, stamping equipment is the core equipment for producing sheet metal parts. It uses molds to apply enormous pressure to metal sheets, causing them to undergo plastic deformation or separation, thereby efficiently and precisely manufacturing various parts.

[0003] Chinese Patent No. CN219520267U discloses sheet metal stamping processing equipment, including a base frame and an upper frame, with four support pillars fixedly installed at the four corners between the base frame and the upper frame. A cylinder is fixedly installed at the top center of the upper frame, and a stamping table is fixedly installed at the top center of the base frame. A sheet metal fixing and limiting mechanism and a stamping head are arranged below the upper frame. The sheet metal fixing and limiting mechanism includes a top cover and a guide tube disposed at the bottom end of the top cover. This utility model, by setting a sheet metal fixing and limiting mechanism, allows a motor to be started when fixing sheet metal. The motor drives a gear to rotate, and a gear ring is connected to one end of the gear and the support arm respectively through the snap teeth on the inner and outer surfaces. The gear drives the gear ring, which in turn drives the support arm to rotate, thereby extending and retracting the support arm. This allows the clamping rod at the other end of the support arm to fix the sheet metal, avoiding manual operation for fixing the sheet metal and increasing the efficiency of sheet metal processing.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: When loading sheet metal stamping equipment, workers need to place the workpiece in the stamping position and fix it, and then take it out again after stamping is completed. This operation is cumbersome, and the production rhythm can be easily affected due to different levels of proficiency, thereby reducing production efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problem of automatic feeding in the prior art by proposing a stamping equipment for sheet metal processing.

A notch is provided on the side of the collecting pipe 510, and the separating plate 513 slides in the notch. The end of the separating plate 513 is set as a pointed tip, which is used to separate two sheet metal workpieces that are attached together when moving, so that a sheet metal workpiece is placed below the separating plate 513, and all the other sheet metal workpieces are blocked above by the separating plate 513. The sheet metal workpieces fall one by one onto the intermittent feeding mechanism for transportation under the coordinated movement of the separating plate 513 and the baffle 511.

[0015] The stamping assembly includes a cylinder 401, a push rod 402, and a stamping plate 403; the cylinder 401 is located at the top of the top plate 3, the push rod 402 is located at the output end of the cylinder 401, and the stamping plate 403 is located at the bottom of the push rod 402.

[0016] The rotating assembly includes a motor 501, a rotating shaft 502, a conveyor plate 503, and a retaining ring 504. The motor 501 is located on the top of the base plate 1, the rotating shaft 502 is located at the output end of the motor 501, the retaining ring 504 is located on the inner side of the support plate 2, and the retaining ring 504 is located between the two support plates 2.

A pressure sensor 505 is provided on the inner side of the placement groove. The conveyor plate 503 integrates a fixing system at the position of the placement groove. After the pressure sensor 505 senses the pressure of the sheet metal workpiece being placed down, the fixing system is activated, thereby clamping the sheet metal workpiece at the center position of the placement groove.

[0017] A connecting frame 506 is provided at the top of the rotating shaft 502, and a conveying box 507 is provided at the end of the connecting frame 506. A mounting block 508 is provided on the side of the conveying box 507 away from the connecting frame 506, and a power shaft 509 is provided at the top of the mounting block 508. The upper part of the conveying box 507 is provided as an inverted conical slot to facilitate the falling sheet metal workpieces to fall into the conveying box 507 for conveying. There are two conveying boxes 507 symmetrically arranged about the connecting frame 506. After the motor 501 starts, it drives the rotating shaft 502 to rotate. The rotating shaft 502 drives the two conveying boxes 507 to rotate through the connecting frame 506. When the conveying box 507 rotates to the placement slot position, it puts the sheet metal workpieces transported inside into the placement slot.

[0018] Example 2; as Figures 3-4 As shown, this utility model proposes a stamping equipment for sheet metal processing. Compared with Embodiment 1, this embodiment details the structure of the intermittent feeding mechanism. The intermittent feeding mechanism includes a fixed frame 517, a baffle 518, a connecting rod 512, and a feeding assembly. The connecting rod 512 is located on the side of the baffle 511, the fixed frame 517 is located at the end of the connecting rod 512, and the baffle 518 is located at the end of the fixed frame 517 away from the connecting rod 512. The baffle 518 is located on the rotation trajectory of the drive shaft 509. Therefore, when the drive shaft 509 rotates to the baffle 518, it will drive the baffle 518 to move together. 8. The baffle 511 and the material distribution plate 513 are moved together by the fixed frame 517 and the connecting rod 512. Since the rotation trajectory of the power shaft 509 is circular, when the material distribution plate 513 and the baffle 511 move to the maximum position to place the sheet metal workpiece, the power shaft 509 just disengages from the partition rod 518, so that the baffle 511 and the material distribution plate 513 return to their original positions. The feeding component is slidably set on the side of the collecting pipe 510 for intermittently feeding the sheet metal workpieces out in sequence. The feeding assembly includes a connecting plate 520, a threaded rod 521, a rotating ring 522, and a sliding frame 523. The connecting plate 520 is disposed on the side of the collecting pipe 510. The threaded rod 521 is threaded onto the inner side of the connecting plate 520. The rotating ring 522 is disposed on the top of the threaded rod 521. The sliding frame 523 is rotatably disposed on the bottom of the threaded rod 521. A second sliding groove 524 is provided on the side of the collecting pipe 510. The second sliding groove 524 and the side of the sliding frame 523 are slidably connected. A telescopic rod 515 is provided on the side of the sliding frame 523. A spring 516 is provided on the outer side of the telescopic rod 515. The telescopic rod 515 is away from the sliding frame 523. A fixed plate 514 is provided at one end of the movable frame 523. A sliding groove 519 is provided at the end of the fixed plate 514. The side of the sliding groove 519 is slidably connected to the end of the connecting rod 512. Rotating the rotating ring 522 drives the threaded rod 521 to rotate. When the threaded rod 521 rotates, it drives the sliding frame 523 to move on the collecting pipe 510. The threaded rod 521 has a triangular thread, so it has a self-locking function. When the sliding frame 523 moves, it drives the dividing plate 513 to move, thereby adjusting the position of the dividing plate 513 according to the thickness of the sheet metal workpiece, so that the tip of the dividing plate 513 points to the gap between the two sheet metal workpieces.

[0019] In summary, when this utility model is used, the motor 501 and cylinder 401 are started. After the motor 501 starts, it drives the rotating shaft 502 to rotate. The rotating shaft 502 drives the two conveying boxes 507 to rotate through the connecting plate 520. When the conveying box 507 rotates to the collecting pipe 510, the power shaft 509 will drive the baffle rod 518 to move together. The baffle rod 518 drives the baffle 511 and the distributing plate 513 to move together through the fixing frame 517 and the connecting rod 512. Since the rotation trajectory of the power shaft 509 is circular, when the distributing plate 513 and the baffle 511 move to the maximum position to put the sheet metal workpiece, the power shaft 509 just disengages from the baffle rod 518, thereby... The baffle 511 and the material distribution plate 513 return to their original positions under the action of the spring 516, and the workpiece falls into the inside through the notch above the conveyor box 507. When the conveyor box 507 continues to rotate to the placement slot position, it puts the sheet metal workpiece transported inside into the placement slot. At this time, the pressure sensor 505 senses the pressure and controls the fixing system and the cylinder 401 to start at the same time. After the fixing system is fixed, the cylinder 401 drives the stamping plate 403 to stamp the workpiece through the push rod 402, thereby completing the stamping work. The output end of the motor 501 is connected to a reducer and rotates at a slow speed. Therefore, during the next workpiece placement period, the operator can open the fixing system to take out the workpiece.

[0020] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
