Description

Technical Field

[0001] The present invention relates to the technical field of stamping machines, and particularly to a one-time stamping machine and a stamping method for processing a valve stator housing. Background Art

[0002] A stamping machine is a mechanical device specifically used for metal forming processing. Its main feature is to complete the required processing steps in a single stamping process, thereby obtaining the required formed parts. The working principle of a one-time stamping machine is based on the action of impact force and pressure. The machine mainly includes three main parts: a punch, a lower die, and an 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 driving device, enabling the upper and lower dies to 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, there are usually two ways to transfer the stamped parts from the die to the subsequent process. One is to precisely pick up the stamped part from the die cavity by a manipulator and smoothly place it at the inlet of the inclined conveyor pipe, ensuring that the stamped part can slide down along the preset path. The other is to use a transfer device (such as a conveyor belt) to accurately convey the stamped part into the inclined conveyor pipe. Subsequently, under the action of gravity, the stamped part slides smoothly along the inner wall of the conveyor pipe until it falls from the outlet at the bottom of the conveyor pipe into a preset receiving box for further processing or storage.

[0004] The prior art has the following defects:

[0005] In the process of transferring the stamped part through the inclined conveyor pipe, the stamped part is likely to come into contact and collide with the inner wall of the conveyor pipe, which may cause scratches, abrasions, deformation or even damage on the surface of the stamped part. When the stamped part falls into the receiving box, it will collide, squeeze or stack disorderly with other stamped parts in the receiving box, resulting in uneven distribution. The dislocation stacking and local accumulation will increase the difficulty of taking out the stamped part in the subsequent process, and the mutual extrusion may affect the dimensional accuracy and surface integrity of the stamped part.

[0006] Therefore, the present application provides a one-time stamping machine and a stamping method for processing a valve stator housing to meet the requirements. Summary of the Invention

[0021] In summary, the technical effects and advantages of the present invention are as follows:

[0022] 1. In the present invention, by arranging the conveying pipe vertically and arranging a conveying assembly inside the conveying pipe, the two conveying disks of the conveying assembly can be combined to catch the stamping parts and move vertically downward. The conveying disks in the conveying assembly are designed as semi-circular and are provided with a material guiding groove at the top. Such a design enables the stamping parts to smoothly slide to the middle of the top of the conveying disks, avoiding direct contact between the stamping parts and the inner wall of the conveying pipe. When the movable wheel slides along the arc part of the slide rail, the two conveying disks move away from each other due to being squeezed, releasing the stamping parts. During the conveying process of the stamping parts inside the conveying disks, they will not come into contact with the inner wall of the conveying pipe, so that scratches, abrasions, deformations, or even damages will not occur on the surface of the stamping parts.

[0023] 2. In the present invention, the design of the positioning component on the movable disk and the receiving box enables each receiving box to correspondingly catch the stamped parts falling from the conveying pipe. Each stamped part has a corresponding receiving box to receive it, and there will be no mutual collision or extrusion with other stamped parts. The design of the ratchet component ensures that the movable disk only rotates counterclockwise when the conveying component rises, and the rotation angle each time is exactly the angle between two adjacent receiving boxes. After each rotation, there is an unused receiving box directly below the lower opening of the conveying pipe, thus ensuring that the unused receiving box can smoothly catch the stamped parts.

[0024] 3. In the present invention, after the stamped parts are released by the conveying component, the storage component can automatically rotate the receiving box to the storage position, and through the cooperation of mechanisms such as the electric push rod and the driving motor, push the receiving box filled with stamped parts into the storage slot, reducing the manual operation links and improving the production efficiency. Moreover, the operator can easily take out the full storage component and install a new one. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment: Refer to Figures 1-11 A shown stamping machine for one-time stamping, including: a stamping machine 1, a punch and a die are arranged on the stamping machine 1, a power device is arranged on the stamping machine 1, the power device provides power for the stamping machine 1, the punch squeezes the workpiece under the drive of the power device, and a cavity for extrusion is opened on the die. The above method for extruding and forming the workpiece is a prior art.

[0040] A discharge frame 101 is fixedly arranged on the stamping machine 1. After stamping, the stamping parts are taken out of the mold by a manipulator and placed into the discharge frame 101. The discharge frame 101 is inclined, and the lower end of the discharge frame 101 is open. A bearing plate 104 is fixedly connected to the side of the stamping machine 1 and near its lower end. A through conveying port is formed in the middle of the bearing plate 104. A conveying pipe 2 is fixedly connected to the top of the bearing plate 104. The upper and lower ends of the conveying pipe 2 are both open. The conveying port of the bearing plate 104 is communicated with the lower end opening of the conveying pipe 2. The lower end opening of the discharge frame 101 is located inside the upper end opening of the conveying pipe 2. The stamping parts can enter the inside of the conveying pipe 2 along the discharge frame 101. Two rectangular notches 21 are symmetrically formed on both sides of the conveying pipe 2. Two arc-shaped notches 22 are symmetrically formed on both sides of the conveying pipe 2 and near its bottom end. The arc-shaped notches 22 are arc-shaped, and the rectangular notches 21 are communicated with the arc-shaped notches 22.

[0041] A conveying assembly 7 is arranged inside the conveying pipe 2. The conveying assembly 7 can catch the stamping parts and convey the stamping parts downward. The conveying assembly 7 includes two symmetrically arranged upper movable plates 71. A through moving notch 711 is formed in the upper movable plate 71. The upper movable plate 71 penetrates through the corresponding rectangular notch 21, and the upper movable plate 71 can vertically move along the rectangular notch 21. One end of the upper movable plate 71 is outside the conveying pipe 2, and the other end of the upper movable plate 71 is inside the conveying pipe 2. A conveying tray 72 is fixedly connected to the end of the upper movable plate 71 inside the conveying pipe 2. The conveying tray 72 is semi-circular. The arc-shaped notch 22 is used for the passing of the conveying tray 72. A material guiding groove is formed in the top of the conveying tray 72. By arranging the material guiding groove, the stamping parts can smoothly enter the middle of the top of the conveying tray 72. Two installation grooves 721 are formed on one side of the two conveying trays 72 close to each other. Two springs 73 are symmetrically arranged between the two conveying trays 72. Both ends of the spring 73 are fixedly installed in the corresponding installation grooves 721. The two conveying trays 72 can move away from or close to each other. When the two conveying trays 72 move close to each other and merge, the spring 73 is hidden inside the corresponding installation groove 721. A bearing ring 77 is arranged inside the conveying pipe 2. The bearing ring 77 is located below the conveying tray 72. Two lower fixing plates 76 are symmetrically and fixedly connected to both sides of the bearing ring 77. The lower fixing plates 76 can vertically move. A threaded hole 761 is formed in the lower fixing plate 76. The upper movable plate 71 is slidably connected above the lower fixing plate 76.

[0042] The conveying assembly 7 further includes two symmetrically arranged slide rails 78 and two rotating pins 74. The bottom ends of the two slide rails 78 are fixedly connected to the bearing plate 104. The slide rails 78 are in front of the upper movable plate 71. The two rotating pins 74 are respectively fixedly connected to the front sides of the corresponding upper movable plates 71. An activity wheel 75 is rotatably connected to the outside of the rotating pin 74. The activity wheel 75 cooperates with the corresponding slide rail 78. The activity wheel 75 is slidably arranged inside the slide rail 78. The slide rail 78 is composed of a vertical portion and an arc portion. The vertical portion is fixedly connected to the top of the arc portion. The bottom of the arc portion is fixedly connected to the bearing plate 104. The arc portion is arranged in cooperation with the arc notch 22. When the activity wheel 75 slides from the vertical portion of the slide rail 78 to the arc portion of the slide rail 78, the arc portion presses the corresponding activity wheel 75, causing the two activity wheels 75 to move away from each other, and then causing the two conveying trays 72 to move away from each other.

[0043] The stamping parts enter the inside of the conveying pipe 2 along the discharge frame 101 and are caught by the two conveying trays 72 in the combined state. The material guiding groove enables the stamping parts to smoothly slide to the middle of the top of the conveying tray 72. Driven by an external force, the two lower fixing plates 76 and the bearing ring 77 move vertically downward as a whole. Since the upper movable plate 71 is slidably connected above the lower fixing plate 76, the two upper movable plates 71, the two conveying trays 72, and the two activity wheels 75 also move vertically downward as a whole. The activity wheels 75 slide downward along the inside of the corresponding slide rails 78. When the activity wheels 75 slide from the vertical portion of the slide rails 78 to the arc portions of the slide rails 78, the arc portions press the corresponding activity wheels 75, causing the two activity wheels 75 to move away from each other, causing the two upper movable plates 71 to move away from each other, and then causing the two conveying trays 72 to move away from each other. The conveying trays 72 pass through the corresponding arc notches 22, and the springs 73 are in a stretched state until the distance between the two conveying trays 72 is greater than the size of the stamping parts. The stamping parts sequentially pass through the distance between the two conveying trays 72, the inside of the bearing ring 77, and the opening at the lower end of the conveying pipe 2.

[0044] The conveying assembly 7 can automatically catch the stamping parts sliding down from the discharge frame 101 and realize the stable conveying of the stamping parts through the two conveying trays 72.

[0045] On the top of the stamping machine 1, a first transmission assembly 5 is symmetrically arranged. The first transmission assembly 5 includes a transmission motor 51 fixedly arranged on the top of the stamping machine 1. The output end of the transmission motor 51 is fixedly connected with a first driving sprocket 52. A threaded rod 55 is rotatably connected to the top of the bearing plate 104. On the side of the stamping machine 1 and near its upper end, an upper mounting plate 102 is fixedly connected. The threaded rod 55 is rotatably connected to the inner side of the upper mounting plate 102, and the threaded rod 55 penetrates through the upper mounting plate 102. The top of the threaded rod 55 is fixedly connected with a first driven sprocket 54. A first chain 53 is drivingly connected between the first driven sprocket 54 and the first driving sprocket 52. The threaded rod 55 is threadedly connected with the threaded hole 761 of the corresponding lower fixing plate 76, and the threaded rod 55 sequentially penetrates through the moving notch 711 and the threaded hole 761. The size of the moving notch 711 is adapted to the horizontal movement track of the conveying tray 72.

[0046] Start the transmission motor 51. The output end of the transmission motor 51 drives the first driving sprocket 52 to rotate. The first driving sprocket 52 drives the first driven sprocket 54 to rotate through the first chain 53. The first driven sprocket 54 drives the threaded rod 55 to rotate, so that the two lower fixing plates 76 and the bearing rings 77 vertically move downward under the combined action of the two threaded rods 55, and then the two upper movable plates 71 and the two conveying trays 72 vertically move downward; when the two upper movable plates 71 move away from each other, relative movement occurs between the upper movable plate 71 and the corresponding lower fixing plate 76, and relative movement occurs between the moving notch 711 and the corresponding threaded rod 55; after the feeding is completed, let the output end of the transmission motor 51 rotate in the reverse direction. The movable wheel 75 slides from the arc portion of the slide rail 78 to the vertical portion of the slide rail 78. Under the resilience of the spring 73, the two conveying trays 72 approach each other, the two upper movable plates 71 approach each other, and the two conveying trays 72 enter the inside of the conveying pipe 2 through the corresponding arc-shaped notches 22 and are combined, and continue to rise to the designated position to prepare for the next material receiving.

[0047] A fixed disk 3 is fixedly arranged below the conveying pipe 2, and a movable disk 13 is rotatably connected above the fixed disk 3. A toothed ring 131 is fixedly sleeved on the outer side of the movable disk 13, and a plurality of positioning components 12 arranged in an annular shape are fixedly connected to the top of the movable disk 13. The positioning component 12 includes two symmetrically arranged positioning plates 121, and the ends of the positioning plates 121 close to the center of the movable disk 13 are arc-shaped. The sides of the two positioning plates 121 close to each other are hinged with action plates 122. A torsion spring 123 is installed on the positioning plate 121, and one end of the torsion spring 123 is fixed to the positioning plate 121. The other end is fixed to the action plate 122. A material receiving box 11 is detachably installed on the inner side of the positioning component 12. A material feeding slot is provided on the top of the material receiving box 11. The material feeding slot is adapted to the stamping part. The side of the action plate 122 close to the material receiving box 11 abuts against the material receiving box 11. By setting the positioning component 12, the material receiving box 11 can be restricted to the inner side of the positioning component 12, so that the material receiving box 11 cannot move. A plurality of electric push rods 9 arranged in a ring shape are fixed on the top of the movable plate 13. The electric push rods 9 are arranged one by one with the positioning components 12, and the telescopic ends of the electric push rods 9 face the positioning components 12.

[0048] A second transmission assembly 6 and a ratchet assembly 8 are symmetrically arranged on the top of the stamping and forming machine 1. The second transmission assembly 6 and the ratchet assembly 8 cooperate with each other to allow the movable disk 13 to intermittently rotate in one direction only. An upper fixed shaft 81 is rotatably connected to the upper mounting plate 102, and the upper fixed shaft 81 passes through the upper mounting plate 102. The second transmission assembly 6 includes a second active sprocket 61 fixedly sleeved on the outer side of the output end of the transmission motor 51, and a lower fixed shaft 83 is rotatably connected to the bearing plate 104. The side of the stamping and forming machine 1 is fixedly connected to the lower mounting plate 103, and the inner side of the lower mounting plate 103 is rotatably connected to the lower fixed shaft 83, and the lower fixed shaft 83 passes through the bearing plate 104 and the lower mounting plate 103. A second driven sprocket 63 is fixedly connected to the top of the upper fixed shaft 81, and a second chain 62 is transmission-connected between the second driven sprocket 63 and the second active sprocket 61. The output end of the transmission motor 51 drives the second driving sprocket 61 to rotate, the second driving 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.

[0049] The ratchet assembly 8 includes an upper fixed shaft 81, a driven drive ring 82, and a lower fixed shaft 83. At the bottom of the upper fixed shaft 81, there is a fixedly connected active drive ring 811. The diameter of the active drive ring 811 is larger than that of the upper fixed shaft 81. At the bottom of the active drive ring 811, there is a fixedly connected driven drive ring 82. An inner ring of the driven drive ring 82 is fixedly connected with a ratchet tooth ring 821. The diameter of the driven drive ring 82 is the same as that of the active drive ring 811. The inner side of the driven drive ring 82 is rotatably connected to the lower fixed shaft 83. The diameter of the lower fixed shaft 83 is the same as that of the upper fixed shaft 81. At the top of the lower fixed shaft 83, there is a fixedly connected fixed cylinder 84. A plurality of annularly distributed receiving grooves are formed on the fixed cylinder 84. A pawl 86 is rotatably connected to the bottom of the receiving groove. A spring piece 85 is installed at the bottom of the receiving groove. The spring piece 85 always pushes the pawl 86 outwards so that the pawl 86 can abut against the ratchet tooth ring 821. At the bottom of the lower fixed shaft 83, there is a fixedly connected transmission gear 87. The transmission gear 87 is meshed and connected with a toothed ring 131.

[0050] When the output end of the driving motor 51 rotates counterclockwise, the first transmission assembly 5 drives the threaded rod 55 to rotate counterclockwise, causing the conveying assembly 7 to move vertically downward. At the same time, the output end of the driving motor 51 drives the second driving sprocket 61 to rotate counterclockwise. The second driving sprocket 61 drives the second driven sprocket 63 to rotate through the second chain 62. The second driven sprocket 63 drives the upper fixed shaft 81 to rotate. The upper fixed shaft 81 drives the active driving ring 811, the driven driving ring 82, and the ratchet gear ring 821 to rotate counterclockwise as a whole. The pawl 86 is continuously compressed inward by the ratchet gear ring 821 and is ejected outward by the spring piece 85. Repeating like this, when the ratchet gear ring 821 rotates counterclockwise, it will not be stuck by the pawl 86. Therefore, the rotation of the driven driving ring 82 will not drive the fixed cylinder 84 to rotate, and thus will not drive the gear ring 131 and the movable disk 13 to rotate as a whole through the transmission gear 87 at the bottom of the fixed cylinder 84. That is, during the process of the conveying assembly 7 moving vertically downward, the movable disk 13 will not rotate. When the output end of the driving motor 51 rotates clockwise, the first transmission assembly 5 drives the threaded rod 55 to rotate clockwise, causing the conveying assembly 7 to move vertically upward. At the same time, the output end of the driving motor 51 drives the second driving sprocket 61 to rotate clockwise. The second driving sprocket 61 drives the second driven sprocket 63 to rotate through the second chain 62. The second driven sprocket 63 drives the upper fixed shaft 81 to rotate. The upper fixed shaft 81 drives the active driving ring 811, the driven driving ring 82, and the ratchet gear ring 821 to rotate clockwise as a whole. The pawl 86 is stuck in the ratchet teeth of the ratchet gear ring 821 by the elastic force of the spring piece 85, forcing the fixed cylinder 84 and the driven driving ring 82 to rotate clockwise together. The fixed cylinder 84 drives the transmission gear 87 at the bottom to rotate clockwise. The transmission gear 87 meshes with the gear ring 131, thereby driving the gear ring 131 to rotate counterclockwise. The gear ring 131 drives the movable disk 13 to rotate counterclockwise. That is, during the process of the conveying assembly 7 moving vertically upward, 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 lower opening of the conveying pipe 2, thus ensuring that one of the receiving boxes 11 can successfully receive the stamped parts.

[0051] A limit frame 10 is fixedly arranged in front of the movable disk 13, and a storage component 4 is installed in front of the movable disk 13. The storage component 4 includes a storage box 41 installed inside the limit frame 10. A storage groove 411 is formed in the top of the storage box 41, and the storage groove 411 can accommodate a plurality of material receiving boxes 11. A docking port 412 is formed in 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 material receiving box 11. Two connecting plates 42 are symmetrically and fixedly connected to the side of the storage box 41 far from the movable disk 13. A lead screw 43 is rotatably connected between the two connecting plates 42. A driving motor 46 is fixedly arranged on the side of one of the connecting plates 42. The output end of the driving motor 46 penetrates through the corresponding connecting plate 42 and is fixedly connected to one end of the lead screw 43. A guide rod 44 is fixedly connected between the two connecting plates 42. A moving plate 45 is threadedly connected to the outside of the lead screw 43, and the moving plate 45 slidably penetrates through the guide rod 44. The moving plate 45 penetrates through the side wall of the storage box 41 and extends into the storage box 41.

[0052] When the output end of the driving motor 51 rotates counterclockwise, the first transmission assembly 5 drives the threaded rod 55 to rotate counterclockwise, causing the conveying assembly 7 to move vertically downward. The movable disk 13 does not rotate, and the stamping part is released under the cooperation of the slide rail 78 and the movable wheel 75. The stamping part successively passes through the spacing between the two conveying disks 72, the inner side of the bearing ring 77, the opening at the lower end of the conveying pipe 2, and the conveying port of the bearing plate 104, and falls into the feeding groove of one of the receiving boxes 11. Then, the output end of the driving motor 51 rotates clockwise, driving the threaded rod 55 to rotate clockwise through the first transmission assembly 5, causing the conveying assembly 7 to move vertically upward until the conveying assembly 7 runs a specified distance and can stably receive materials. During the process of the conveying assembly 7 moving vertically upward, the movable disk 13 rotates counterclockwise, rotating the next receiving box 11 at the rear to directly below the conveying pipe 2 for receiving materials, and the receiving box 11 that has completed receiving materials rotates to the position corresponding to the storage assembly 4 in the front. Then, the corresponding electric push rod 9 is started, and the telescopic end of the electric push rod 9 extends and abuts against the receiving box 11 that has completed receiving materials. The moving plate 122 rotates outward under the extrusion force of the receiving box 11, and the telescopic end of the electric push rod 9 pushes the receiving box 11 into the storage slot 411 through the docking port 412. After the receiving box 11 disengages from the inside of the positioning assembly 12, the moving plate 122 returns to its original position under the action of the torsion spring 123. The electric push rod 9 is started to make its telescopic end return to its original position, and the driving motor 46 is started. The output end of the driving motor 46 drives the lead screw 43 to rotate, causing the moving plate 45 to move in the direction of the driving motor 46 under the guiding action of the guiding rod 44. The moving plate 45 pushes the receiving box 11 that has completed receiving materials to the side of the storage slot 411 close to the driving motor 46. After waiting for the conveying assembly 7 above to complete receiving materials again, the processes of receiving and storing materials are completed again in the above manner until the storage slot 411 contains a specified number of receiving boxes 11. Then, the storage assembly 4 is taken out, and a new storage assembly 4 is installed inside the limiting frame 10.

[0053] It should be noted that during the above process, after the telescopic end of the electric push rod 9 returns to its original position, when installing a new receiving box 11 inside the positioning assembly 12 where the receiving box 11 is missing at this time, it is necessary to complete the installation of the new receiving box 11 before the next feeding and before the conveying assembly 7 moves vertically downward to prepare for releasing the stamping part.

[0054] A stamping method for processing a valve stator housing includes the following steps: A power device provides power for a stamping machine 1, and a punch extrudes and forms the valve stator housing under the drive of the power device.
