Description

Technical Field

[0001] The invention relates to the technical field of stamping and forming machine equipment, and in particular to a one-step stamping and forming machine and a stamping method for processing a valve stator housing. Background Art

[0002] A stamping machine is a mechanical device specially used for metal forming. Its main feature is that it completes the required processing steps in one stamping process to obtain the required formed parts. The working principle of a one-shot stamping machine is based on the effects of impact force and pressure. The machine mainly consists of three main parts: the punch, the lower die and the upper die. During the processing, the operator places the metal sheet to be processed on the workbench of the stamping machine and positions and clamps it according to the processing requirements. Then, the transmission system provides power through the drive device, so that the upper and lower dies process the metal sheet with a certain impact force and pressure.

[0003] In the stamping process of the prior art, after the stamping machine completes the stamping operation of the workpiece, it usually uses two methods to transfer the stamped parts from the mold to the subsequent process. First, the stamped parts are accurately taken out of the mold cavity by a manipulator and placed steadily at the entrance of the inclined conveying pipe to ensure that the stamped parts can slide along the preset path. Second, the stamped parts are accurately transferred to the inclined conveying pipe using a transmission device (such as a conveyor belt). Subsequently, the stamped parts slide down along the inner wall of the conveying pipe under the action of gravity until they fall into the preset receiving box from the outlet at the bottom of the conveying pipe for further processing or storage.

[0004] The prior art has the following defects: In the process of transporting the stamped parts through an inclined conveying tube, the stamped parts are prone to contact and collide with the inner wall of the conveying tube, which may cause scratches, strains, deformation or even damage to the surface of the stamped parts. When the stamped parts fall into the receiving box, they will collide, be squeezed or stacked disorderly with other stamped parts in the receiving box, resulting in uneven distribution. Misplaced stacking and local accumulation will increase the difficulty of the stamped parts in the subsequent removal process. Mutual squeezing may affect the dimensional accuracy and surface integrity of the stamped parts.

[0005] Therefore, the present application provides a one-step stamping machine and a stamping method for valve stator housing processing to meet the needs. Summary of the invention

When the ratchet gear ring 821 rotates counterclockwise, it will not be stuck by the pawl 86, so the rotation of the driven driving ring 82 will not drive the fixed column 84 to rotate, and then the gear ring 131 and the movable disk 13 will not be driven to rotate as a whole through the transmission gear 87 at the bottom of the fixed column 84, that is, during the vertical downward movement of the conveying assembly 7, the movable disk 13 will not rotate; when the output end of the transmission motor 51 rotates clockwise, the threaded rod 55 is driven to rotate clockwise through the first transmission assembly 5, so that The conveying assembly 7 moves vertically upward, and at the same time, the output end of the transmission motor 51 drives the second active sprocket 61 to rotate clockwise, and the second active sprocket 61 drives the second driven sprocket 63 to rotate through the second chain 62, and the second driven sprocket 63 drives the upper fixed shaft 81 to rotate, and the upper fixed shaft 81 drives the active drive ring 811, the driven drive ring 82, and the ratchet gear ring 821 to rotate clockwise as a whole, and the pawl 86 is stuck in the ratchet teeth of the ratchet gear ring 821 by the elastic force of the spring sheet 85, forcing the fixed column 84 and the driven drive ring 82 to rotate clockwise together, and the fixed The column 84 drives the transmission gear 87 at the bottom to rotate clockwise, and the transmission gear 87 meshes with the gear ring 131, thereby driving the gear ring 131 to rotate counterclockwise, and the gear ring 131 drives the movable disk 13 to rotate counterclockwise, that is, during the vertical upward movement of the conveying component 7, the movable disk 13 rotates counterclockwise, and the angle of each counterclockwise rotation of the movable disk 13 is exactly the angle between two adjacent receiving boxes 11, so that one of the receiving boxes 11 is directly below the opening at the lower end of the conveying tube 2, thereby ensuring that one of the receiving boxes 11 can smoothly receive the stamping part.

[0039] A limit frame 10 is fixedly set in front of the movable disk 13, and a storage assembly 4 is installed in front of the movable disk 13. The storage assembly 4 includes a storage box 41 installed inside the limit frame 10. A storage slot 411 is opened on the top of the storage box 41, and the storage slot 411 can accommodate multiple receiving boxes 11. A docking port 412 is opened on the side of the storage box 41 close to the movable disk 13, and the docking port 412 is used for the passage of the receiving boxes 11. Two connecting plates 42 are symmetrically fixedly connected to the side of the storage box 41 away from the movable disk 13, and a screw rod 43 is rotatably connected between the two connecting plates 42. A driving motor 46 is fixedly set on the side of one of the connecting plates 42, and the output end of the driving motor 46 passes through the corresponding connecting plate 42 and is fixedly connected to one end of the screw rod 43. A guide rod 44 is fixedly connected between the two connecting plates 42, and a movable plate 45 is threadedly connected to the outer side of the screw rod 43, and the movable plate 45 slides through the guide rod 44. The movable plate 45 passes through the side wall of the storage box 41 and extends to the interior of the storage box 41.

[0040] When the output end of the transmission motor 51 rotates counterclockwise, the threaded rod 55 is driven to rotate counterclockwise through the first transmission assembly 5, so that the conveying assembly 7 moves vertically downward, and the movable disk 13 does not rotate. The stamping parts are released under the cooperation of the slide rail 78 and the movable wheel 75. The stamping parts pass through the gap between the two conveying disks 72, the inner side of the carrying ring 77, the opening at the lower end of the conveying pipe 2, and the conveying port of the carrying plate 104 in turn, and fall into the feeding trough of one of the receiving boxes 11. Then the output end of the transmission motor 51 rotates clockwise, and the threaded rod 55 is driven to rotate clockwise through the first transmission assembly 5, so that the conveying assembly 7 moves vertically upward until the conveying assembly 7 runs a specified distance and the conveying assembly 7 can stably receive materials. During the vertical upward movement of the conveying assembly 7, the movable disk 13 rotates counterclockwise to rotate the next receiving box 11 at the rear to the bottom of the conveying pipe 2 for receiving materials, and the receiving box 11 that has completed receiving materials rotates to the position of the corresponding storage assembly 4 in front, and then the corresponding electric push rod 9 is started. The telescopic end of the electric push rod 9 extends and contacts the receiving box 11 after receiving the material. The action plate 122 rotates outward under the extrusion force of the receiving box 11. The telescopic end of the electric push rod 9 pushes the receiving box 11 into the storage groove 411 through the docking port 412. After the receiving box 11 is separated from the inner side of the positioning assembly 12, the action plate 122 returns to its original position under the action of the torsion spring 123. The electric push rod 9 is started to restore its telescopic end to its original position. The drive motor 46 is started, and the output end of the drive motor 46 drives the screw rod 43 rotates, so that the movable plate 45 moves toward the direction of the driving motor 46 under the guidance of the guide rod 44, and the movable plate 45 pushes the receiving box 11 that has completed receiving the material to the side of the storage groove 411 close to the driving motor 46, and waits for the conveying component 7 above to complete the material receiving again. In the above manner, the material receiving and storing process is completed again until the storage groove 411 accommodates a specified number of receiving boxes 11, then the storage component 4 is taken out, and a new storage component 4 is installed on the inner side of the limit frame 10.

[0041] It should be noted that: in the above process, after the telescopic end of the electric push rod 9 returns to its original position, a new receiving box 11 is installed on the inner side of the positioning assembly 12 of the missing receiving box 11. The installation of the new receiving box 11 needs to be completed before the next feeding and the conveying assembly 7 moves vertically downward to prepare for releasing the stamping part.
