Description

Technical Field

[0001] This invention relates to the field of automotive parts stamping technology, specifically to an automotive parts stamping forming apparatus. Background Technology

[0002] The exhaust pipe is part of the exhaust system of a car engine, and the outer wall of the exhaust pipe has several rows of holes that need to be stamped.

[0003] Chinese patent application number CN202322519025.X discloses a punching device for exhaust pipes, including a workbench with a first support platform for support. By placing a mandrel on a second support platform, a first electric push rod drives a first clamping plate to move and clamp and fix the mandrel. A second electric push rod drives a second clamping plate to move closer and clamp and fix the exhaust pipe. The punching operation of the exhaust pipe can be completed by the punching mechanism.

[0004] However, both the loading and unloading of the exhaust pipes require manual placement and handling, resulting in high labor intensity and low work efficiency.

[0005] Therefore, the applicant has developed a new technical solution in the actual production process to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the aforementioned technical shortcomings, the purpose of this invention is to provide an automotive parts stamping and forming apparatus that enables automatic feeding and unloading of exhaust pipes.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] The present invention provides a stamping forming apparatus for automotive parts, including a material storage assembly, a pushing assembly and a stamping assembly, wherein the material storage assembly is used to horizontally stack various exhaust pipes to be processed;

[0009] The stamping assembly includes a punch assembly located on one side of the storage assembly and a die assembly that cooperates with the punch assembly. The pushing assembly pushes the die assembly to reciprocate in the horizontal direction.

[0010] The pushing component, in conjunction with a limiting component, first pushes the single exhaust pipe at the bottom of the storage component into the die assembly, and then pushes the die assembly and the exhaust pipe together into the punch assembly through the limiting component. The punch assembly and the die assembly cooperate to perform the stamping operation of the exhaust pipe. At this time, the limiting component restricts the exhaust pipe in the storage component from moving downward. The stamping component is equipped with a rotating component, which cooperates with the limiting component to make the exhaust pipe located on the die assembly rotate.

[0011] When the pushing component moves the die assembly toward the storage component, the limiting component pushes the processed exhaust pipe away from the die assembly, and then the limiting component is driven by the pushing component to move out of the storage component along with the die assembly.

[0012] By adopting the above technical solution, the storage component places multiple exhaust pipes to be processed in a horizontal direction and stacks them layer by layer, which facilitates the pushing component to push the single horizontally distributed exhaust pipe to the stamping component. In order to facilitate the automatic unloading of the processed exhaust pipes, the die assembly can move back and forth in the horizontal direction. When the exhaust pipe needs to be stamped, the pushing component pushes the die assembly and the exhaust pipe together into the lower part of the punch assembly through the limiting component to stamp the exhaust pipe, realizing automatic feeding. After the stamping is completed, when the pushing component drives the die assembly to move towards the storage component, the limiting component pushes the processed exhaust pipe away from the die assembly, which facilitates the automatic unloading of the exhaust pipe. The setting of the rotating component allows the exhaust pipe to rotate at multiple angles for stamping, realizing the purpose of automatic feeding and unloading of the exhaust pipe. In addition, it can be automatically fixed during stamping.

[0013] Preferably, the die assembly includes a plug for inserting the exhaust pipe and a punch hole formed on the plug for punching by the punch assembly. The punch assembly includes a drive member located on one side of the material storage assembly and punch rods distributed corresponding to the punch holes. The drive member simultaneously drives each punch rod to move up and down reciprocally.

[0014] Preferably, the storage assembly includes conical hoppers with their openings facing upwards and a vertical pipe disposed at the lower end of the conical hoppers. The conical hoppers are used to store multiple exhaust pipes and to discharge the exhaust pipes one by one into the vertical pipes for horizontal stacking. The lower end of the vertical pipes is provided with through holes for inserting rods and limiting members to pass through.

[0015] Preferably, the pushing component includes a mounting cylinder fixed to one side of the vertical pipe and a power source disposed on the mounting cylinder. The limiting member includes a limiting cylinder that slides along the length of the mounting cylinder and is connected inside the mounting cylinder. The insertion rod passes through the limiting cylinder. The power source pushes the insertion rod to move within the limiting cylinder. The through hole allows the limiting cylinder to pass through.

[0016] During the process of the power source driving the insertion rod to be inserted into the exhaust pipe, the mounting cylinder is provided with a fixing component that restricts the movement of the limiting cylinder along with the insertion rod. After the insertion rod is inserted into the exhaust pipe, the fixing component releases the restriction on the limiting cylinder, so that the limiting cylinder is driven to move together by the power source.

[0017] Preferably, the rotating component includes a rotating ring rotatably connected to the end of the limiting cylinder facing the stamping assembly, a chuck located on the side of the punch assembly away from the material storage assembly, and a power component for driving the chuck to rotate. The chuck is provided with a slot for inserting one end of the insertion rod. The pushing component pushes one end of the exhaust pipe to the chuck surface through the limiting cylinder, causing one end of the insertion rod to enter the slot. The exhaust pipe is fixed by the chuck and the rotating ring, causing the power component to drive the chuck to rotate.

[0018] Preferably, the fixing component includes several fixing boxes disposed on the side of the mounting cylinder near the vertical pipe, and each fixing box is slidably connected to a pressing block. Each fixing box is fitted with an elastic element that facilitates one end of the pressing block to enter or move out of the limiting cylinder. When the limiting cylinder is subjected to an elastic force that overcomes the elastic force applied to the pressing block by the elastic element, the pressing block moves out of the limiting cylinder.

[0019] The fixing component also includes a push plate disposed on the insertion rod. Both the limiting cylinder and the mounting cylinder have openings for the lower end of the push plate to extend out of the limiting cylinder and the mounting cylinder. One end of the opening on the mounting cylinder passes through the mounting cylinder and faces the storage assembly. One end of the opening on the limiting cylinder extends to one side of the rotating ring. A retaining ring is fixedly connected to the inner wall of the limiting cylinder on the side of the insertion rod with the push plate.

[0020] Preferably, the die assembly further includes a support cylinder slidably connected to the lower end of the vertical tube and communicating with the vertical tube. The support cylinder allows a single exhaust pipe to enter. A push plate is used to push the support cylinder to move together with the insert rod after the insert rod is inserted into the exhaust pipe located in the support cylinder. The vertical tube is provided with a return member that causes the support cylinder to move towards the storage assembly when the insert rod moves towards the storage assembly.

[0021] Preferably, the support cylinder has a blanking hole corresponding to the punching hole.

[0022] Preferably, it also includes a receiving assembly located below the stamping assembly, the receiving assembly including a receiving box located on one side of the stamping assembly, the receiving assembly being used to transfer the exhaust pipe after stamping to the receiving box.

[0023] Preferably, the receiving assembly further includes several inclined rods located below the stamping assembly, the multiple inclined rods forming a grid-like filter screen, and the gaps between adjacent inclined rods are used for the passage of waste material after stamping.

[0024] The beneficial effects of this invention are as follows: the storage assembly places multiple exhaust pipes to be processed in a horizontal direction and stacks them layer by layer, which facilitates the pushing assembly to push the single horizontally distributed exhaust pipes to the stamping assembly. In order to facilitate the automatic unloading of the processed exhaust pipes, the die assembly can move back and forth in the horizontal direction. When the exhaust pipe needs to be stamped, the pushing assembly pushes the die assembly and the exhaust pipe together into the lower part of the punch assembly through the limiting member to stamp the exhaust pipe, realizing automatic feeding. After the stamping is completed, when the pushing assembly drives the die assembly to move towards the storage assembly, the limiting member pushes the processed exhaust pipe away from the die assembly, which facilitates the automatic unloading of the exhaust pipe. The setting of the rotating member allows the exhaust pipe to rotate at multiple angles for stamping, realizing the purpose of automatic feeding and unloading of the exhaust pipe. In addition, it can be automatically fixed during stamping. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 scope of protection of the present invention.

[0042] An automotive parts stamping forming apparatus, such as Figure 1 and Figure 2It includes a storage assembly 1, a pushing assembly 2, and a stamping assembly 3. The storage assembly 1 is used to horizontally stack the various exhaust pipes 4 to be processed. The horizontal stacking of the exhaust pipes 4 means that the exhaust pipes 4 are placed horizontally and stacked one layer on top of the other; for example Figure 1 and Figure 2 The stamping assembly 3 includes a punch assembly located on one side of the storage assembly 1 and a die assembly that cooperates with the punch assembly. The pushing assembly 2 pushes the die assembly to reciprocate in the horizontal direction.

[0043] The pushing component 2, in conjunction with the limiting component, first pushes the single exhaust pipe 4 at the bottom of the storage component 1 into the die assembly. Then, the limiting component pushes the die assembly and the exhaust pipe 4 together into the punch assembly. The punch assembly and the die assembly work together to stamp the exhaust pipe 4. At this time, the limiting component restricts the exhaust pipe 4 in the storage component 1 from moving downward. The stamping component 3 is equipped with a rotating component. The rotating component works with the limiting component to make the exhaust pipe 4 located on the die assembly rotate. After the exhaust pipe 4 is stamped, the pushing component 2 drives the die assembly to move towards the storage component 1. The limiting component pushes the processed exhaust pipe 4 away from the die assembly. Then, the limiting component is driven by the pushing component 2 to move out of the storage component 1 along with the die assembly, which facilitates the loading of the exhaust pipe 4 for the next time.

[0044] like Figure 1 and Figure 2 The storage component 1 places multiple exhaust pipes 4 to be processed in a horizontal direction and stacks them layer by layer, so that the pushing component 2 can push the single horizontally distributed exhaust pipe 4 to the stamping component 3. In order to facilitate the automatic unloading of the exhaust pipe 4 after processing, the die assembly can move back and forth in the horizontal direction. When the exhaust pipe 4 needs to be stamped, the pushing component 2 pushes the die assembly and the exhaust pipe 4 together into the punch assembly through the limiting component to stamp the exhaust pipe 4 and realize automatic feeding. After the stamping is completed, when the pushing component 2 drives the die assembly to move towards the storage component 1, the limiting component pushes the processed exhaust pipe 4 away from the die assembly, which facilitates the automatic unloading of the exhaust pipe 4. The setting of the rotating component allows the exhaust pipe 4 to rotate at multiple angles for stamping, realizing the purpose of automatic feeding and unloading of the exhaust pipe 4. In addition, it can be automatically fixed during stamping.

[0045] like Figures 1-8The die assembly includes a insert rod 31 into which the air supply and exhaust pipe 4 is inserted, and punch holes 311 formed on the insert rod 31 for the punch assembly to punch. The length direction of each punch hole 311 is vertically distributed, and the arrangement direction of each punch hole 311 is the length direction of the insert rod 31. The punch assembly includes a worktable 32 located on one side of the material storage assembly 1, a driving component set on the worktable 32, and punch rods 321 distributed corresponding to the punch holes 311. The driving component simultaneously drives each punch rod 321 to move up and down reciprocally. The driving component includes an inverted U-shaped fixing frame 322 set on the upper end face of the worktable 32. The worktable 32 is a horizontally distributed plate, and the upper end face of the worktable 32... A horizontal plate 323 is mounted on several mounting rods 3231. The horizontal plate 323 is located inside a fixed frame 322. A horizontal plate 3233 is slidably connected to the upper surface of the horizontal plate 323 by several mounting rods 3232. The upper ends of the mounting rods 3232 are fixed to the horizontal surface of the fixed frame 322. An electric cylinder 33 is provided on the upper surface of the fixed frame 322 to drive the horizontal plate 3233 to move up and down. The upper ends of each punch rod 321 are fixed to the lower surface of the horizontal plate 3233, and the lower ends protrude from the lower surface of the horizontal plate 323. At this time, the punch rod 321 slides inside the horizontal plate 323 as the horizontal plate 3233 moves up and down.

[0046] like Figures 1-8 The storage assembly 1 includes a conical hopper 11 with its opening facing upwards and a vertical pipe 12 located at the lower end of the conical hopper 11. Each conical hopper 11 has a rod supporting it on its outer wall. The conical hopper 11 includes two vertically distributed upright plates and an inclined plate connecting the two ends of the upright plates. Each upright plate is a trapezoidal plate with its longer bottom edge facing upwards and its shorter bottom edge connected to the vertical pipe 12. The lower end of the inclined plate is also connected to the vertical pipe 12. The conical hopper 11 is used to store multiple exhaust pipes 4 and to discharge the exhaust pipes 4 one by one into the vertical pipe 12 for horizontal stacking. The lower end of the vertical pipe 12 has a through hole 121 for the insertion rod 31 and the limiting member to pass through.

[0047] like Figures 1-8The pushing component 2 includes an installation cylinder 21 fixed to one side of the vertical pipe 12 and a power source disposed on the installation cylinder 21. The installation cylinder 21 is horizontally distributed along its length. The power source can be an electric cylinder 22. The lower ends of the installation cylinder 21 and the electric cylinder 22 are provided with several rods supporting the installation cylinder 21 and the electric cylinder 22. The limiting component includes a limiting cylinder 23 that slides along the length of the installation cylinder 21 and is connected inside the installation cylinder 21. Both ends of the limiting cylinder 23 have openings. The insertion rod 31 passes through the limiting cylinder 23. In order to facilitate the insertion rod 31 entering the limiting cylinder 23, the end of the insertion rod 31 away from the electric cylinder 22 can be set as The piston rod of the second electric cylinder 22 (not shown in the figure) enters the mounting cylinder 21 and is fixedly connected to the end of the insertion rod 31. The second electric cylinder 22 is used to push the insertion rod 31 to move within the limiting cylinder 23. In order to reduce the rotation of the insertion rod 31 during the movement, guide grooves 312 are provided on both relatively horizontal sides of the insertion rod 31. The inner wall of the limiting cylinder 23 is provided with a guide strip 231 extending into the guide groove 312. When the insertion rod 31 moves within the limiting cylinder 23, the guide strip 231 moves within the guide groove 312 to reduce the rotation of the insertion rod 31. The insertion rod passes through the hole 121 for the limiting cylinder 23 to pass through.

[0048] like Figures 1-8 When the power source drives the insertion rod 31 to be inserted into the exhaust pipe 4, the mounting cylinder 21 is provided with a fixing member that restricts the movement of the limiting cylinder 23 along with the insertion rod 31. After the insertion rod 31 is inserted into the exhaust pipe 4, the fixing member releases the restriction on the limiting cylinder 23, so that the limiting cylinder 23 is driven to move together by the power source.

[0049] like Figures 1-8 The rotating component includes a rotating ring 232 rotatably connected to the end of the limiting cylinder 23 facing the stamping assembly 3, a chuck 34 located on the side of the punch assembly away from the material storage assembly 1, and a power component for driving the chuck 34 to rotate. The power component includes a vertical plate 341 disposed on the upper surface of the worktable 32 and a motor 342 fixed on the vertical plate 341. The rotation shaft of the motor 342 extends out of the vertical plate 341 and is coaxially fixedly connected to the chuck 34. The rotating ring 232 is coaxially distributed with the limiting cylinder 23, and the inner wall of the rotating ring 232 is flush with the inner wall of the limiting cylinder 23. At this time, the rotating ring 232 rotates at a constant speed. Ring 232 is also coaxially distributed with chuck 34. Slot 343 for inserting one end of insertion rod 31 is coaxially provided on chuck 34. Pushing component 2 pushes one end of exhaust pipe 4 to the chuck 34 surface through rotating ring 232 on limiting cylinder 23, so that one end of insertion rod 31 is located in slot 343. At this time, rotating ring 232 presses exhaust pipe 4 against the chuck 34 surface. The exhaust pipe 4 is fixed by chuck 34 and rotating ring 232, so that power component drives chuck 34 to rotate. At this time, exhaust pipe 4 rotates on the outer wall of insertion rod 31.

[0050] like Figures 1-8The fixing components include several fixing boxes 24 disposed on the side of the mounting cylinder 21 near the vertical tube 12. Each fixing box 24 is distributed circumferentially around the outer wall of the mounting cylinder 21, but is not disposed directly below the mounting cylinder 21 to facilitate the subsequent movement of the push plate 35. Each fixing box 24 is slidably connected to a pressing block 241. The fixing box 24 is fitted with an elastic element that facilitates one end of the pressing block 241 to enter or exit the limiting cylinder 23. When the limiting cylinder 23 is subjected to an elastic force that overcomes the elastic force applied to the pressing block 241 by the elastic element, the pressing block 241 moves out of the limiting cylinder 23.

[0051] like Figures 1-8 The elastic element includes a compression spring 242 located between the extrusion block 241 and the bottom of the fixing box 24. The compression spring 242 causes the extrusion block 241 to be inserted into the limiting cylinder 23. The outer walls of both ends of the limiting cylinder 23 in the length direction are provided with slots for the extrusion block 241 to enter. The relative groove walls of each slot are inclined surfaces 233. One end of the two inclined surfaces 233 is connected to each other, and the other end extends to the groove opening. The opposite two sides of the extrusion block 241 are respectively provided with inclined surfaces 234 that cooperate with the two inclined surfaces 233. The two inclined surfaces 233 and the two inclined surfaces 234 are distributed along the length direction of the limiting cylinder 23. When the limiting cylinder 23 moves back and forth in the mounting cylinder 21, the inclined surfaces 234 can press the inclined surfaces 233, thereby causing the extrusion block 241 to move out of the slot and release the limitation of the mounting cylinder 21 on the limiting cylinder 23.

[0052] like Figures 1-8 The fixing component also includes a push plate 35 set on the insertion rod 31. At this time, the push plate 35 is located at the end of the insertion rod 31 near the electric cylinder 22. Both the limiting cylinder 23 and the mounting cylinder 21 have openings 25 for the lower end of the push plate 35 to extend out of the limiting cylinder 23 and the mounting cylinder 21. The width of the opening 25 on the mounting cylinder 21 is smaller than the width of the opening 25 on the limiting cylinder 23. One end of the opening 25 on the mounting cylinder 21 passes through the mounting cylinder 21 and faces the storage component 1. One end of the opening 25 on the limiting cylinder 23 extends to the side of the rotating ring 232. At this time, the lower end of the vertical tube 12 has a notch 122 for the push plate 35 to move. The limiting cylinder 23 has a retaining ring 26 fixedly connected to the inner wall of the side of the insertion rod 31 with the push plate 35. The piston rod of the electric cylinder 22 passes through the retaining ring 26 and connects to the end of the insertion rod 31. At this time, the retaining ring 26 is coaxially distributed with the limiting cylinder 23 and is located on one side of the insertion rod 31.

[0053] like Figures 1-8It also includes a receiving assembly located below the stamping assembly 3. The receiving assembly includes a receiving box 36 located on one side of the stamping assembly 3. The receiving assembly is used to transfer the exhaust pipe 4 after stamping to the receiving box 36. The lower end face of the worktable 32 is provided with several rods to support the worktable 32 off the ground. The worktable 32 is provided with a removal hole 37 for the processed exhaust pipe 4 to fall to the lower end face of the worktable 32. The receiving assembly also includes several tilting rods 371 located below the stamping assembly 3. At this time, the tilting rods 371 are set on the worktable. On the lower end face of the worktable 32 and on the side of the removal hole 37 away from the receiving box 36, multiple inclined rods 371 form a grid-like filter. The gap between adjacent inclined rods 371 is used for the passage of waste material after stamping. At this time, when the stamping assembly 3 is stamping the exhaust pipe 4, the waste material falls through the removal hole 37 and then falls to the ground through the gap between adjacent inclined rods 371. After stamping is completed, the exhaust pipe 4 falls from the removal hole 37 to the lower end face of the worktable 32 and slides down along the inclined rods 371 into the receiving box 36.

[0054] like Figures 1-8 Working principle:

[0055] The first step is the process of the insertion rod 31 cooperating with the exhaust pipe 4: When the exhaust pipe 4 needs to be processed, the electric cylinder 22 works to push the insertion rod 31 towards the stamping assembly 3 until the insertion rod 31 enters the first exhaust pipe 4. The first exhaust pipe 4 is the exhaust pipe 4 located at the lowest end of the vertical pipe 12. One end of the insertion rod 31 extends out of the first exhaust pipe 4 towards the side facing the stamping assembly 3 and the push plate 35 contacts the rotating ring 232.

[0056] The second step involves the exhaust pipe 4 being moved out of the storage assembly 1 and fixed below the punch rod 321: The electric cylinder 22 continues to drive the insert rod 31 towards the stamping assembly 3, causing the push plate 35 on the insert rod 31 to drive the rotating ring 232 to also move towards the stamping assembly 3. Since the rotating ring 232 is rotatably connected to the limiting cylinder 23, the limiting cylinder 23 is also moved towards the stamping assembly 3 via the rotating ring 232. This causes the inclined surface 234 on the limiting cylinder 23 to press against the inclined surface 233, thereby pushing the pressing block 241 out of the slot and releasing the mounting cylinder 21 from the slot. The limiting cylinder 23 restricts the movement of the limiting cylinder 23 towards the punch rod 321. The wall thickness of the limiting cylinder 23 is less than the wall thickness of the exhaust pipe 4, which facilitates the pushing of the first exhaust pipe 4 located in the vertical pipe 12 out of the vertical pipe 12 by the side of the limiting cylinder 23 with the rotating ring 232. At this time, the push plate 35 moves in the notch 122 of the vertical pipe 12 until the limiting cylinder 23 completely pushes the first exhaust pipe 4 out of the vertical pipe 12, and makes one end of the first exhaust pipe 4 abut against the plate surface of the chuck 34. At this time, the end of the insertion rod 31 enters the slot 343.

[0057] At this time, the first exhaust pipe 4 and the insert rod 31 are both located directly below the punch rod 321, so that each punch hole 311 on the insert rod 31 and each punch rod 321 are opposite to each other. The limiting cylinder 23 is mostly located inside the vertical pipe 12, and each extrusion block 241 is opposite to each slot of the limiting cylinder 23 located in the mounting cylinder 21 and enters into each slot, forming a lock on the limiting cylinder 23. At this time, the limiting cylinder 23 supports the exhaust pipe 4 inside the vertical pipe 12 and restricts the other exhaust pipes 4 from moving downward.

[0058] The third step is the stamping process: the electric cylinder 33 drives the horizontal plate 3233 to move downward, causing each punch 321 to move downward until the lower end of the punch 321 moves through the punch hole 311 to the bottom of the insert rod 31. At this time, the first exhaust pipe 4 is stamped, realizing automatic feeding.

[0059] Step 4, stamping process: After the motor 342 drives the chuck 34 to rotate a certain angle and then stops rotating, the motor 342 is a servo motor 342, which causes the chuck 34 and the rotating ring 232 to also drive the first exhaust pipe 4 to rotate a certain angle, thus facilitating the punch 321 to stamp the first exhaust pipe 4 again, until the hole on the first exhaust pipe 4 is stamped (e.g., Figure 13 The line connecting any two opposite holes on the exhaust pipe 4 passes through the axis of the exhaust pipe 4, so that the punch can completely penetrate the exhaust pipe 4.

[0060] Step 5, after stamping, the exhaust pipe 4 separates from the insert rod 31 and is unloaded: After stamping, the electric cylinder 22 drives the insert rod 31 to move towards the mounting cylinder 21 in the opposite direction. At this time, the rotating ring 232 on the end face of the limiting cylinder 23 will abut against the outer wall of the first exhaust pipe 4. As the insert rod 31 continues to move, the limiting cylinder 23 pushes the first exhaust pipe 4 away from the insert rod 31. During this process, the extrusion block 241 is always located in each slot, so that the position of the limiting cylinder 23 is stable. After the first exhaust pipe 4 separates from the insert rod 31, as the insert rod 31 continues to move towards the mounting cylinder 21, the insert rod 31 abuts against the retaining ring 26. At this time, as the insert rod 31 continues to move towards the mounting cylinder 21, the insert rod 31 will drive the limiting cylinder 23 to move together through the retaining ring 26, so that each extrusion block 241 separates from the slot.

[0061] After separation, the rotating ring 232 moves away from the first exhaust pipe 4, and the two ends of the first exhaust pipe 4 lose the squeezing force, causing the first exhaust pipe 4 to fall off. The first exhaust pipe 4 falls through the removal hole 37 onto each tilting rod 371, and is then guided into the receiving box 36, thereby realizing automatic feeding.

[0062] Step 6, Return Process: The insertion rod 31 drives the limiting cylinder 23 back into the mounting cylinder 21, so that each extrusion block 241 enters the slot of the insertion rod 31 near the vertical tube 12. This is the initial state of the first step. Each exhaust pipe 4 in the vertical tube 12 moves down one position so that the next exhaust pipe 4 is facing the insertion rod 31. Repeat steps 1 to 6, and so on, to achieve the purpose of automatic feeding and unloading of exhaust pipe 4 during stamping.

[0063] like Figures 9-12 To reduce the deformation of the exhaust pipe 4 during stamping, the die assembly also includes a support cylinder 38 that is slidably connected to and communicates with the lower end of the vertical tube 12. At this time, the vertical tube 12 does not have a through hole 121 and a notch 122. The support cylinder 38 is slidably connected to the lower end of the vertical tube 12. Both ends of the support cylinder 38 in the horizontal direction are cylinder openings, and the upper end is a communication port communicating with the lower end of the vertical tube 12. The support cylinder 38 allows a single exhaust pipe 4 to enter. The push plate 35 is used to push the support cylinder 38 and the limiting cylinder 23 to move together with the insert rod 31 after the insert rod 31 is inserted into the exhaust pipe 4 located in the support cylinder 38. The vertical tube 12 is provided with a return member that causes the support cylinder 38 to move towards the storage component 1 when the insert rod 31 moves towards the storage component 1.

[0064] like Figures 9-12 The return component includes a fixed plate 381 disposed on the side of the vertical tube 12 near the mounting cylinder 21, and a movable plate 382 fixedly connected to the outer wall of the support cylinder 38. A tension spring 383 is provided between the movable plate 382 and the fixed plate 381. A guide rod 384 is provided on the movable plate 382 and passes through the tension spring 383. The end of the guide rod 384 away from the movable plate 382 passes through the fixed plate 381, that is, the guide rod 384 slides on the fixed plate 381. When the support cylinder 38 moves together with the insertion rod 31 to below the punch rod 321, the tension spring 383 is in its original state. When the support cylinder 38 is below the vertical tube 12, the vertical tube 12 has a baffle 385 on the side wall with the fixed plate 381 to restrict the position of the support cylinder 38. The baffle 385 has a hole for the push plate 35 to abut against the side wall of the support cylinder 38. At this time, the tension spring 383 is also in a stretched state.

[0065] like Figures 9-12 The support cylinder 38 has a discharge hole 39 corresponding to the punch 311, which facilitates the removal of the punched waste material from the exhaust pipe 4 from the support cylinder 38. The lower end of the punch rod 321 is removed from the discharge hole 39. The support cylinder 38 limits the bottom of the exhaust pipe 4 and reduces the deformation of the bottom of the exhaust pipe 4 during punching.

[0066] like Figures 9-12 Working principle:

[0067] Steps one, three, and four are the same as described above;

[0068] In the second step described above, the process of moving the exhaust pipe 4 out of the storage assembly 1 and fixing it below the punch rod 321: the electric cylinder 22 continues to drive the insert rod 31 to move towards the stamping assembly 3, causing the push plate 35 on the insert rod 31 to drive the rotating ring 232 to also move towards the stamping assembly 3. At this time, since the rotating ring 232 is rotatably connected to the limiting cylinder 23, the limiting cylinder 23 is also driven to move towards the stamping assembly 3 through the rotating ring 232, causing the inclined surface 234 on the limiting cylinder 23 to press the inclined surface 233, thereby pushing the extrusion block 241 out of the slot and releasing it. In addition to the restriction of the limiting cylinder 23 by the mounting cylinder 21, which facilitates the movement of the limiting cylinder 23 towards the punch rod 321, the side of the limiting cylinder 23 with the rotating ring 232 pushes the first exhaust pipe 4 located in the vertical tube 12 to move out of the support cylinder 38, so that one end of the first exhaust pipe 4 moves out of the support cylinder 38. Then the push plate 35 abuts against the side wall of the support cylinder 38, driving the support cylinder 38 to move together towards the punch rod 321. The length of the tension spring 383 is stretched. At this time, the material dropping hole 39 on the support cylinder 38 is opposite to each punch hole 311.

[0069] Until the limiting cylinder 23 completely pushes the first exhaust pipe 4 out of the vertical pipe 12, and one end of the first exhaust pipe 4 abuts against the surface of the chuck 34, at which point the end of the insert rod 31 enters the slot 343;

[0070] At this time, the first exhaust pipe 4, the insert rod 31, and the support cylinder 38 are all located directly below the punch rod 321, so that each punch hole 311 on the insert rod 31 and each punch rod 321 are opposite to each other. The limiting cylinder 23 is mostly located inside the vertical pipe 12, and each extrusion block 241 is opposite to each slot of the limiting cylinder 23 located in the mounting cylinder 21 and enters into each slot, forming a lock on the limiting cylinder 23. At this time, the limiting cylinder 23 supports the exhaust pipe 4 inside the vertical pipe 12 and restricts the other exhaust pipes 4 from moving downward.

[0071] Step 5: After stamping, the exhaust pipe 4 separates from the insert rod 31 during the unloading process: After stamping, the electric cylinder 22 reverses and drives the insert rod 31 to move towards the mounting cylinder 21. Under the tension of the tension spring 383, the support cylinder 38 also moves with the insert rod 31 until one end of the support cylinder 38 touches the baffle 385, causing the support cylinder 38 to move again to the lower end of the vertical pipe 12 and connect with the vertical pipe 12. At this time, the rotating ring 232 on the end face of the limiting cylinder 23 will abut against the outer wall of the first exhaust pipe 4, and with the insert rod 31... As the movement continues, the limiting cylinder 23 pushes the first exhaust pipe 4 away from the insert rod 31. During this process, the extrusion block 241 remains within each slot, stabilizing the position of the limiting cylinder 23. After the first exhaust pipe 4 separates from the insert rod 31, the insert rod 31 continues to move towards the mounting cylinder 21, causing the insert rod 31 to abut against the retaining ring 26. As the insert rod 31 continues to move towards the mounting cylinder 21, the insert rod 31 will drive the limiting cylinder 23 to move together through the retaining ring 26, causing each extrusion block 241 to separate from the slot.

[0072] After separation, the rotating ring 232 moves away from the first exhaust pipe 4, and the two ends of the first exhaust pipe 4 lose the squeezing force, causing the first exhaust pipe 4 to fall off. The first exhaust pipe 4 falls through the removal hole 37 onto each tilting rod 371, and is then guided into the receiving box 36, thereby realizing automatic feeding.

[0073] Step 6, Return Process: The insertion rod 31 drives the limiting cylinder 23 back into the mounting cylinder 21, so that each extrusion block 241 enters the slot of the insertion rod 31 near the vertical tube 12. This is the initial state of the first step. Each exhaust pipe 4 in the vertical tube 12 moves down one position into the support cylinder 38, so that the next exhaust pipe 4 is facing the insertion rod 31. Repeat steps 1 to 6, and so on, to achieve the purpose of automatic feeding and unloading of exhaust pipe 4 during stamping.
