Description

Technical Field

[0001] The invention relates to the field of powder molten metal additive manufacturing, and in particular to an automatic cylinder transport device for powder molten metal additive printing equipment. Background Art

[0002] At present, in the field of powder molten metal additive manufacturing, the products printed by 3D printing equipment need to be removed by the 3D printing equipment's own transfer mechanism. The workers then transfer the formed cylinder offline through overhead cranes or forklifts for processing in the next process. Conversely, the empty cylinder is put online and workers transfer it to the 3D printing equipment's own transfer mechanism through overhead cranes or forklifts. The transfer mechanism then moves the empty cylinder to the 3D printing equipment's working position for printing.

[0003] The related technology uses a slide assembly to drive the lifting assembly to move left and right, so that the lifting assembly drives the fork assembly thereon to move to the position of the cylinder body, and the fork assembly drives the fork thereon to move to the upper part of the cylinder body. The cylinder body is self-centered by a group of support blocks at the front end of the fork and the support blocks on the cylinder body, so that the fork and the cylinder body are connected together, thereby driving the cylinder body to move.

[0004] However, the above connection method will make the end of the fork rigidly connected to the cylinder body, so that when the fork picks up the cylinder body and moves it forward and backward or when the slide assembly drives the cylinder body to move left and right, the fork will immediately drive the cylinder body to move synchronously. Since the inside of the cylinder body is full of powder, the weight of the cylinder body is heavy, which makes the inertia of the cylinder body large. The printing material inside the cylinder body will shake or even move relative to the cylinder body under the action of inertia, and there is a risk of material dumping. Summary of the invention

[0018] The beneficial effects of the present invention are as follows: 1.

[0019] 2. The present invention adopts a speed control component to control the speed of the cylinder moving with the slide assembly.

[0020] 3.

On the one hand, it can prevent air from contacting the material inside the cylinder body, causing oxidation of the printed material. On the other hand, the flow and compression of the air inside the annular airbag can further buffer the movement of the cylinder body, further preventing the material inside the cylinder body from dumping.

DETAILED DESCRIPTION

[0034] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0035] See also Figure 1 , Figure 2 and Figure 3 A cylinder automatic handling device for a powder molten metal additive printing device includes a slide assembly 1, a lifting assembly 2 is slidably arranged on the slide assembly 1 along its track, a fork assembly 3 is arranged inside the lifting assembly 2, the fork assembly 3 includes a fork 31 connected to the lifting assembly 2 through a power guide mechanism 33, a sealing cover 32 controlled by a cylinder is arranged inside the front end of the fork 31 for sliding up and down, the fork assembly 3 also includes a buffer mechanism 34 for buffering the movement of the cylinder body, and the fork assembly 3 also includes a sealing mechanism 35 for assisting the sealing cover 32.

[0036] First, the device is arranged on the production line of the printing equipment so that the device can cover all the printing equipment and auxiliary equipment on the production line. Then the workshop main control system releases production tasks and instructions according to the order. The AGV cart transports the empty cylinder body to the loading and unloading platform. After receiving the instruction, the device takes the empty cylinder body from the loading and unloading platform and places it on the loading and unloading port of the 3D metal printing equipment. The 3D metal printing equipment automatically performs printing according to the instruction requirements. After printing is completed, the formed cylinder body is moved out to the loading and unloading port. Then, after receiving the instruction, the device moves to the workstation of the 3D metal printing equipment and takes out the printed formed cylinder body. Then, the device drives the formed cylinder body to move to the next workstation.

[0037] When the device is transporting the forming cylinder body, first the slide assembly 1 drives the fork assembly 3 to move horizontally to the left and right to the position of the forming cylinder body through the lifting assembly 2, and then the power guide mechanism 33 drives the fork 31 to move forward to the upper part of the forming cylinder body, and then the buffer mechanism 34 connects the fork 31 to the forming cylinder body, and at the same time pushes the forming cylinder body upward to contact with the sealing mechanism 35, so that the sealing mechanism 35 seals the upper opening of the forming cylinder body, and then the lifting assembly 2 drives the forming cylinder body to move upward by moving the fork assembly 3 upward.

[0038] Then the power guide mechanism 33 drives the forming cylinder body to move backward to the loading and unloading port away from the 3D metal printing equipment through the fork 31. During this process, the buffer mechanism 34 buffers the movement of the forming cylinder body to prevent the material inside the forming cylinder body from dumping. Then the slide assembly 1 moves horizontally to drive the forming cylinder body to the next workstation. During this process, the buffer mechanism 34 can also buffer the movement of the forming cylinder body to further prevent the material inside the forming cylinder body from dumping. Finally, the fork 31 extends and places the forming cylinder body at the loading and unloading port of the next workstation. Finally, after repeatedly transporting the forming cylinder body and stopping at all workstations, the device transports the forming cylinder body to the unloading platform of the production line of the printing equipment, thereby completing the transportation of a forming cylinder body.

[0039] See also Figure 2 , Figure 3 and Figure 4 The buffer mechanism 34 includes two symmetrically arranged movable plates 341 which are set inside the fork 31 by sliding left and right through a guide column. The buffer mechanism 34 also includes placement plates 342 which are fixedly installed on the left and right sides of the cylinder body by bolts. A buffer plate 343 is set on the side of the movable plate 341 close to the cylinder body for sliding back and forth. A connecting component 344 is set between the buffer plate 343 and the placement plate 342 at the corresponding position.

[0040] See also Figure 3 and Figure 4 The connecting assembly 344 includes three No. 1 connecting blocks 3441 fixedly installed at equal intervals along the front-to-back direction on the side of the buffer plate 343 close to the cylinder body. The connecting assembly 344 also includes three No. 2 connecting blocks 3442 fixedly installed at equal intervals along the front-to-back direction on the side of the placement plate 342 away from the cylinder body. The No. 1 connecting block 3441 and the No. 2 connecting block 3442 are both in a right-angled trapezoidal structure, and the inclined surfaces of the No. 1 connecting block 3441 and the No. 2 connecting block 3442 at the corresponding position are opposite to each other.

[0041] Continue reading Figure 3 and Figure 4 A V-shaped groove 3443 is provided on the inclined surface of the No. 1 connecting block 3441 located in the middle, and a triangular protrusion 3444 is fixedly installed on the inclined surface of the No. 2 connecting block 3442 located in the middle, and the shape of the triangular protrusion 3444 corresponds to that of the V-shaped groove 3443.

[0042] See also Figure 3 , Figure 4 and Figure 5 An isosceles trapezoidal connecting groove 3445 is provided on the inclined surface of the No. 1 connecting block 3441 located on the front and rear sides, and an isosceles trapezoidal connecting slider 3446 is fixedly installed on the inclined surface of the No. 2 connecting block 3442 located on the front and rear sides. The connecting slider 3446 is located at the lower position of the inclined surface of the No. 2 connecting block 3442.

[0043] The operator fixes the placement plate 342 on the left and right side surfaces of the cylinder body in advance. When the fork 31 moves forward to the cover set on the upper part of the forming cylinder body, the fork 31 drives the two buffer plates 343 to move to the left and right side positions of the forming cylinder body through the moving plate 341, and makes the position of the buffer plate 343 correspond to the placement plate 342, so that the buffer plate 343 drives the No. 1 connecting block 3441 thereon to correspond to the position of the No. 2 connecting block 3442 at the corresponding position.

[0044] See also Figure 3 , Fig. 9 and Fig.10 A support plate 346 is fixedly installed in the middle of the fork 31, and a sliding plate 347 is slidably arranged on the support plate 346. The sliding plate 347 is connected to the two movable plates 341 through a synchronization component 348. The synchronization component 348 includes two sliding plates 3481 symmetrically arranged on the support plate 346 for sliding left and right. The front part of the sliding plate 3481 is fixedly connected to the movable plate 341 at the corresponding position, and a synchronization plate 3482 is rotatably connected to the middle part of the rear side of the sliding plate 347. Both ends of the synchronization plate 3482 are hinged to the sliding plate 3481 through a hinge plate 3483, and a No. 1 hydraulic rod 3484 is fixedly connected between the two sliding plates 3481.

[0045] See also Figure 2 , Fig. 9 , Fig.10 and Fig.11 The buffer mechanism 34 also includes a speed control component 349 arranged on the support plate 346 for controlling the moving speed of the sliding plate 347. The speed control component 349 includes a No. 2 hydraulic rod 3491 fixedly installed on the upper part of the support plate 346. A push plate 3492 and a speed control component 3493 are slidingly arranged inside the support plate 346. The lower part of the push plate 3492 is connected to the speed control component 3493 through a No. 2 spring damping rod 3497. The telescopic section of the No. 2 hydraulic rod 3491 is fixedly connected to the push plate 3492, and a push rod 3494 is fixedly installed on the lower part of the push plate 3492.

[0046] See also Fig.10 and Fig.11 The upper part of the sliding plate 347 is in a V-shaped structure, and the lower part of the speed control component 3493 is in a pointed structure corresponding to the V-shaped structure of the sliding plate 347. A connecting groove 3495 is fixedly provided on the pointed structure of the speed control component 3493, and an insertion block 3496 for inserting into the connecting groove 3495 is fixedly provided on the V-shaped structure of the sliding plate 347 in a symmetrical manner on the left and right.

[0047] In the initial state, the telescopic section of the second hydraulic rod 3491 is in an extended state, so that the telescopic section of the second hydraulic rod 3491 pushes the push plate 3492 downward, causing the push plate 3492 to abut against the upper side of the speed control member 3493 through the push rod 3494, so that the pointed structure at the lower part of the speed control member 3493 is inserted into the V-shaped structure of the sliding plate 347 through the push of the push rod 3494, and then the speed control member 3493 pushes the sliding plate 347 to lock in the middle position of the support plate 346. At the same time, the sliding plate 347 drives the rotation center of the synchronous plate 3482 to also be located in the middle position of the support plate 346, and at this time, the second spring damping rod 3497 is in a compressed state, and the insertion block 3496 is not inserted into the connecting groove 3495.

[0048] Subsequently, the telescopic section of the No. 1 hydraulic rod 3484 is retracted, so that the No. 1 hydraulic rod 3484 drives the two movable plates 341 to approach each other through the sliding plate 3481. At the same time, the sliding plate 3481 pushes the synchronous plate 3482 to rotate through the hinge plate 3483, so that the synchronous plate 3482 can drive the two movable plates 341 to move synchronously in opposite directions relative to their rotation centers, so that the two movable plates 341 drive the inclined surface of the No. 1 connecting block 3441 to move synchronously to the inclined surface of the No. 2 connecting block 3442 that is attached to the corresponding position through the buffer plate 343.

[0049] In the process of the inclined surface of the No. 1 connecting block 3441 and the inclined surface of the No. 2 connecting block 3442 at the corresponding position contacting and fitting each other, the middle connecting block No. 1 3441 drives the V-shaped groove 3443 thereon to move to the outside of the triangular protrusion 3444 of the middle connecting block No. 2 3442, and the triangular protrusion 3444 is inserted into the interior of the V-shaped groove 3443, so that the two inclined surfaces of the triangular protrusion 3444 are aligned and fitted with the two inclined surfaces of the V-shaped groove 3443, so that the position of the No. 1 connecting block 3441 and the corresponding position of the No. 2 connecting block 3442 is adjusted to be exactly corresponding.

[0050] Then continue to retract the telescopic section of the No. 1 hydraulic rod 3484, so that the No. 1 connecting blocks 3441 on the left and right sides continue to move synchronously toward the middle of the fork 31, so that the inclined surface of the No. 1 connecting block 3441 and the inclined surface of the No. 2 connecting block 3442 slide relative to each other, so that the No. 1 connecting block 3441 pushes the No. 2 connecting block 3442 upward, and the No. 2 connecting block 3442 drives the forming cylinder body to move upward synchronously through the placement plate 342.

[0051] During this process, the connecting grooves 3445 on the connecting block No. 1 3441 on the front and rear sides slide to the outside of the connecting slider 3446 of the connecting block No. 2 3442 at the corresponding position, and the connecting grooves 3445 and the connecting slider 3446 are connected, so that the connecting block No. 1 3441 and the connecting block No. 2 3442 are slidably connected together. When the connecting block No. 1 3441 is against the placement plate 342, the connecting block No. 1 3441 is locked into a whole with the forming cylinder body, so that the buffer plate 343 and the forming cylinder body are also locked into a whole, and then the sliding plate 347 can move left and right synchronously with the forming cylinder body.

[0052] See also Figure 2 , Figure 3 and Figure 8 The sealing mechanism 35 includes a baffle plate 351 fixedly mounted on the fork 31 by inserting a column into the lower side of the sealing cover 32, an annular air bag 352 is fixedly mounted on the inner side of the baffle plate 351, and an air pump 353 connected to the annular air bag 352 is fixedly mounted on the upper part of the fork 31.

[0053] In the initial state, the annular airbag 352 is in an unexpanded state, and the upper side of the annular airbag 352 abuts against the lower side of the sealing cover 32. When the No. 1 connecting block 3441 abuts against the placement plate 342, the upper end of the forming cylinder moves upward to the outside of the annular airbag 352, and then the air pump 353 is used to blow air into the inside of the annular airbag 352, so that the annular airbag 352 begins to expand, so that the annular airbag 352 is filled between the baffle plate 351, the sealing cover 32 and the outside of the cylinder body, thereby sealing the upper mouth of the forming cylinder body to prevent the material inside the forming cylinder body from being oxidized.

[0054] See also Figure 3 , Figure 4 , Figure 6 and Figure 7 A force release assembly 345 is arranged between the buffer plate 343 and the movable plate 341 at the corresponding position. The force release assembly 345 includes two spring damping rods 3451 symmetrically arranged front and back and fixedly installed inside the movable plate 341. A follower block 3452 slidably connected to the movable plate 341 is fixedly installed in the middle of the buffer plate 343 away from the cylinder body.

[0055] See also Figure 6 and Figure 7 The force release assembly 345 also includes an active plate 3453 and a tooth plate 3454 which are slidably connected to the inside of the moving plate 341 up and down. The tooth plate 3454 is connected to the upper part of the active plate 3453 through a spiral spring. The tooth plate 3454 is located at the lower part of the follower block 3452. Two groups of teeth are symmetrically arranged on the tooth plate 3454 front and back, and each group is composed of teeth fixedly installed on the tooth plate 3454 at equal intervals along the front and back.

[0056] Continue reading Figure 6 and Figure 7 The force release assembly 345 also includes an electric push rod 3455 fixedly installed inside the moving plate 341, the telescopic section of the electric push rod 3455 is fixedly connected to the active plate 3453, and a clamping plate 3456 is fixedly installed on the middle part of the lower side of the follower block 3452.

[0057] After the annular airbag 352 seals the upper opening of the forming cylinder body, the lifting assembly 2 drives the forming cylinder body upward through the fork 31, and then the power guide mechanism 33 drives the fork 31 to move backward. At this time, the telescopic section of the electric push rod 3455 is synchronously contracted, so that the electric push rod 3455 drives the active plate 3453 to move upward, and the active plate 3453 pushes the tooth plate 3454 to rest on the lower side of the card plate 3456 through the coil spring.

[0058] When the fork 31 moves backward, the forming cylinder remains still under the action of inertia, so that the forming cylinder drives the buffer plate 343 to remain still synchronously, and then when the fork 31 starts to move backward, the fork 31 drives the moving plate 341 to move backward relative to the buffer plate 343, and the moving plate 341 drives the front spring damping rod 3451 No. 1 to press against the follower block 3452 and compress. As the front spring damping rod 3451 No. 1 is gradually compressed, the elastic force of the spring damping rod 3451 No. 1 increases, and the thrust required for its compression gradually increases, so that the inertia of the forming cylinder gradually begins to be unable to compress the front spring damping rod 3451 No. 1 through the follower block 3452, and then the front spring damping rod 3451 No. 1 slowly drives the forming cylinder to move backward.

[0059] When the movable plate 341 moves backward relative to the buffer plate 343, the movable plate 341 drives the tooth plate 3454 to move backward relative to the clamping plate 3456, so that the clamping plate 3456 contacts the inclined surface of a group of teeth on the front side of the clamping plate 3454 one by one, and drives the clamping plate 3454 to move downward intermittently by pushing the teeth downward. When the No. 1 spring damping rod 3451 on the front side pushes the forming cylinder body to move backward to the same speed as the moving fork 31, the clamping plate 3456 and the tooth plate 3454 are relatively stationary, so that the coil spring pushes the vertical section of the tooth of the clamping plate 3454 through its own elastic force to block the clamping plate 3456, preventing the No. 1 spring damping rod 3451 on the front side from pushing the follower block 3452 to move backward relative to the buffer plate 343, thereby avoiding the forming cylinder body from moving too fast and ensuring the stability of the forming cylinder body.

[0060] When the fork 31 starts to move backward, the fork 31 drives the annular airbag 352 to move synchronously, so that the forming cylinder squeezes the annular airbag 352 forward through its own inertia, and the gas inside the front side of the annular airbag 352 moves to its rear side, thereby ensuring that the annular airbag 352 fills the gap between the baffle plate 351, the sealing cover 32 and the outer side of the forming cylinder, thereby ensuring the sealing effect, and through the compression of the air inside the annular airbag 352, the start-up of the forming cylinder can also be buffered, further increasing the buffering effect.

[0061] When the fork 31 drives the forming cylinder to move backward to the specified position, the power guide mechanism 33 stops driving the fork 31, so that the fork 31 drives the forming cylinder to slowly stop, and then the telescopic section of the electric push rod 3455 is extended to drive the tooth plate 3454 to no longer block the card plate 3456, so that the front side No. 1 spring damping rod 3451 slowly pushes the follower block 3452 through its own elastic force, so that the follower block 3452 moves to the middle initial position of the moving plate 341.

[0062] It should be noted that, in the initial state, the spring damper rods 3451 on the front and rear sides are in a pre-compression state, so that when the spring damper rod 3451 on the front side pushes the follower block 3452 backward to reset, it has sufficient elastic force to push the follower block 3452 to the middle initial position of the moving plate 341, and through the blocking of the spring damper rod 3451 on the rear side, the follower block 3452 can be kept in the middle initial position of the moving plate 341 by pushing the spring damper rods 3451 on the front and rear sides forward and backward when the moving plate 341 is stationary.

[0063] Then the slide assembly 1 drives the forming cylinder to move right to the next workstation through the fork 31. When the slide assembly 1 is started, the telescopic section of the No. 2 hydraulic rod 3491 is contracted, so that the push rod 3494 no longer pushes the speed control part 3493, but the elastic force of the No. 2 spring damping rod 3497 pushes the speed control part 3493 to still fit on the V-shaped structure of the sliding plate 347. When the fork 31 moves to the right, the forming cylinder remains stationary due to the action of inertia, so that the forming cylinder drives the sliding plate 347 to move left relative to the speed control part 3493, so that the right inclined surface of the V-shaped structure of the sliding plate 347 pushes the speed control part 3493 upward, and the speed control part 3493 gradually compresses the No. 2 spring damping rod 3497.

[0064] At the same time, the connecting groove 3495 on the right side of the speed control component 3493 is slidably connected to the insertion block 3496 on the right side of the sliding plate 347, so that the speed control component 3493 and the sliding plate 347 are slidably connected together. As the sliding plate 347 gradually compresses the No. 2 spring damping rod 3497, the elastic force of the No. 2 spring damping rod 3497 gradually increases, making it increasingly difficult for the sliding plate 347 to push the speed control component 3493 upward, and then the speed control component 3493 begins to drive the forming cylinder body to move slowly to the right through the sliding plate 347.

[0065] At the same time, the annular airbag 352 further cushions the movement of the forming cylinder body through the same principle. When the forming cylinder body and the fork 31 move at the same speed, the elastic force of the No. 2 spring damping rod 3497 slowly pushes the speed control component 3493 downward, so that the speed control component 3493 drives the sliding plate 347 to slowly move to the middle position of the support plate 346, and then extends the telescopic section of the No. 2 hydraulic rod 3491 again to press the speed control component 3493 on the sliding plate 347, so that the forming cylinder body and the fork 31 move stably at the same speed. When the fork 31 drives the forming cylinder body to move to the right to the specified position, the slide assembly 1 stops driving the fork 31, so that the fork 31 drives the forming cylinder body to slowly stop.

[0066] Subsequently, the power guide mechanism 33 extends the fork 31 to drive the forming cylinder body to move forward and backward to the work station. The annular airbag 352 and the buffer plate 343 buffer the forming cylinder body through the same principle as above, and then extends the No. 1 hydraulic rod 3484 to drive the moving plates 341 on both sides away from each other, thereby placing the forming cylinder body on the work station.

[0067] See also Figure 1-Figure 11 When the forming cylinder body is transported to the next workstation, the present invention also includes the following steps: In the first step, the slide assembly 1 drives the fork assembly 3 to move horizontally to the position of the forming cylinder body through the lifting assembly 2, and then the power guide mechanism 33 drives the fork 31 to move forward to the upper part of the forming cylinder body.

[0068] In the second step, the telescopic section of the No. 1 hydraulic rod 3484 is retracted to drive the No. 1 connecting block 3441 to connect to the No. 2 connecting block 3442, and the forming cylinder body is driven to move upward synchronously by pushing the No. 2 connecting block 3442 upward, so that the upper end of the forming cylinder body moves upward to the outside of the annular airbag 352.

[0069] The third step is to blow air into the annular airbag 352 through the air pump 353 so that the annular airbag 352 is filled between the baffle plate 351, the sealing cover 32 and the outer side of the cylinder body, thereby sealing the upper opening of the forming cylinder body to prevent the material inside the forming cylinder body from being oxidized.

[0070] In the fourth step, the lifting assembly 2 drives the forming cylinder body upward through the fork 31, and then the power guide mechanism 33 drives the fork 31 to move backward. At this time, the telescopic section of the electric push rod 3455 is synchronously contracted, so that the electric push rod 3455 drives the active plate 3453 to move upward, and the active plate 3453 pushes the tooth plate 3454 to rest on the lower side of the card plate 3456 through the coil spring.

[0071] In the fifth step, when the fork 31 moves backward, the forming cylinder remains still under the action of inertia, and the No. 1 spring damping rod 3451 on the front side pushes the forming cylinder to move slowly backward through its gradually increasing elastic force to prevent the material inside the forming cylinder from dumping, and when the moving speed of the forming cylinder and the fork 31 are consistent, the clamping plate 3456 cooperates with the clamping tooth plate 3454 to prevent the No. 1 spring damping rod 3451 on the front side from pushing the follower block 3452 to move backward relative to the buffer plate 343, thereby ensuring the stability of the forming cylinder.

[0072] In the sixth step, the fork 31 drives the annular airbag 352 to move synchronously, so that the forming cylinder squeezes the annular airbag 352 forward through its own inertia, and the gas inside the front side of the annular airbag 352 moves to its rear side, thereby ensuring that the annular airbag 352 fills the gap between the baffle plate 351, the sealing cover 32 and the outer side of the forming cylinder, thereby ensuring the sealing effect, and through the compression of the air inside the annular airbag 352, the start-up of the forming cylinder can also be buffered, further increasing the buffering effect.

[0073] In the seventh step, when the fork 31 drives the forming cylinder to move backward to the specified position, the power guide mechanism 33 stops driving the fork 31, so that the fork 31 drives the forming cylinder to slowly stop, and then the telescopic section of the electric push rod 3455 is extended to drive the tooth plate 3454 to no longer block the card plate 3456, so that the front side No. 1 spring damping rod 3451 slowly pushes the follower block 3452 to move to the middle initial position of the moving plate 341 through its own elastic force.

[0074] In the eighth step, the slide assembly 1 drives the forming cylinder body to move right to the next workstation through the fork 31, and at the same time contracts the telescopic section of the No. 2 hydraulic rod 3491. The forming cylinder body drives the sliding plate 347 to drive the speed control part 3493 to gradually compress the No. 2 spring damping rod 3497. The elastic force of the No. 2 spring damping rod 3497 gradually drives the forming cylinder body to move slowly to the right.

[0075] In the ninth step, when the forming cylinder body and the fork 31 move at the same speed, the elastic force of the No. 2 spring damping rod 3497 slowly drives the sliding plate 347 to move to the middle position of the support plate 346, and then the telescopic section of the No. 2 hydraulic rod 3491 is extended again to press the speed control part 3493 on the sliding plate 347, so that the forming cylinder body and the fork 31 move stably at the same speed. When the fork 31 drives the forming cylinder body to move backward to the specified position, the slide assembly 1 stops driving the fork 31, so that the fork 31 drives the forming cylinder body to stop slowly.

[0076] In the tenth step, the power guide mechanism 33 extends the fork 31 to drive the forming cylinder body to move forward and backward to the work station. The annular airbag 352 and the buffer plate 343 buffer the forming cylinder body through the same principle as above, and then extends the No. 1 hydraulic rod 3484 to drive the moving plates 341 on both sides to move away from each other, thereby placing the forming cylinder body on the work station.
