Description

Technical Field

[0001] The invention relates to the field of forging dies, and more particularly to a large-size thick-core and thin-arm forging die. Background Art

[0002] Large-size thick-core and thin-arm forging dies are designed for forgings with larger sizes, thick center parts and thinner edges (arms). Such dies play an important role in the field of forging forming and shaping of difficult-to-deform materials. The dies usually include a matching forging upper die and a forging lower die, both of which are provided with a model cavity that matches the shape of the forging. For large-size thick-core and thin-arm forgings, the model cavity needs to be precisely designed as a cross configuration or other complex shapes to ensure the accuracy and consistency of the forging after forming.

[0003] During the design process, the size, shape, wall thickness and other factors of the forging need to be fully considered to ensure the applicability and durability of the mold. The mold material needs to have good heat resistance, wear resistance and deformation resistance to withstand the high temperature and high pressure environment during the forging process. Common mold materials include high alloy steel, cemented carbide, etc. The mold structure needs to be reasonably designed to improve the strength and rigidity of the mold and reduce the risk of deformation and damage of the mold during the forging process. At the same time, auxiliary facilities such as the mold cooling system and exhaust system need to be considered to ensure the smooth progress of the forging process.

[0004] In the prior art, since the forgings will produce oxide scale due to their own surface oxidation before forging, after preliminary scraping, the forgings will still produce oxide scale when they are forged inside the die cavity. In addition, during the forging process, part of the oxide scale will adhere to or fall inside the die cavity when the forgings are taken out after forming. If the oxide scale is not handled in time, it will cause local pits on the surface of the forging. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention discharges air flow through the provided air outlet and blows away the oxide scale remaining inside the pre-forging chamber and the final forging chamber, and the sealing plate can seal the air outlet. Since the female mold and the male mold can clean the oxide scale remaining inside the pre-forging chamber and the final forging chamber after forging the forging, it is avoided that the oxide scale that is not processed in time will cause local pits on the surface of the forging during subsequent forging, thereby ensuring the forging quality of the forging.

[0020] (2) The present invention drives the rotating drum to rotate the two first magnetic blocks through the guide rod, and pushes the push block through the magnetism of the first magnetic blocks, and the timing of pushing different push blocks is controllable. Since the positions of the two first magnetic blocks will be swapped each time the cylinder (101) drives the male mold up and down, the magnetic poles of the two first magnetic blocks will face different directions, so that one of the push blocks pushes the structure of the jacking component, and the push blocks pushed by each reciprocating up and down side of the male mold are different, and are closely related to the forging frequency of the male mold on the forging, so as to control the jacking component to push the sealing plate to block the air outlet, and further improve the fan's efficiency in blowing away oxide scale.

[0021] (3) The present invention pushes the blocking plate by means of a top block, so that two of the four air outlets are always blocked by the blocking plate. Since the opening of the two air outlets at the corresponding positions will be controlled as the forgings are taken out of the pre-forging chamber or the final forging chamber, the airflow generated by the fan can be accurately used for chip blowing. At the same time, two of the air outlets will be blocked each time, so that the wind speed of the airflow blown out of the other two air outlets will increase, thereby further improving the fan's chip blowing efficiency for the oxide scale.

[0035] See also Figures 1 to 10 A large-size thick-core thin-arm forging die comprises a workbench 1 and a female die 2 movably connected to the lower side of the inner surface of the workbench 1, a cylinder 101 is fixedly installed on the upper side of the inner part of the workbench 1, a male die 3 is fixedly connected to the bottom end of the cylinder 101, a fan 4 is fixedly installed on the back of the workbench 1, and the fan 4 is connected to the workbench 1, a pre-forging chamber 7 is provided on the left side of the opposite surface of the female die 2 and the male die 3, a final forging chamber 8 is provided on the right side of the opposite surface of the female die 2 and the male die 3, a chip blowing component 5 is provided inside the workbench 1 and on the upper side of the male die 3, and the chip blowing component 5 comprises a connecting plate 51 fixedly connected to the upper side of the male die 3;

[0036] A slide groove 52 is provided at the upper front end of the workbench 1, and a connecting plate 51 is slidably connected in the slide groove 52. A pressure sensor 53 is fixedly installed on the upper inner side of the slide groove 52. After the upper side of the connecting plate 51 moves upward, it is squeezed and contacted with the lower side of the pressure sensor 53. An air outlet 54 is provided at the front end of the workbench 1 above the mother mold 2, and there are four air outlets 54. A sealing plate 55 is slidably connected to the inside of the four air outlets 54, and the shape of the sealing plate 55 is adapted to the shape of the air outlet 54.

[0037] By adopting the above technical solution, the forging is first placed in the pre-forging chamber 7 opened above the female mold 2, and then the male mold 3 is pushed downward by the cylinder 101 equipped on the workbench 1 itself. After the male mold 3 is fitted with the female mold 2, the two pre-forging chambers 7 between the male mold 3 and the female mold 2 will complete the pre-shaping of the forging. After the cylinder 101 lifts the male mold 3, the pre-shaped forging can be transferred to the final forging chamber 8, and then the male mold 3 is pushed downward by the cylinder 101 again, so that the two final forging chambers 8 between the male mold 3 and the female mold 2 perform final shaping on the forging. In the process of the male mold 3 being lifted upward by the cylinder 101, the connecting plate 51 above the male mold 3 will slide in the slide groove 52 inside the workbench 1. When the connecting plate 51 is connected with the pressure sensor 53 above the slide groove 52, After being touched, the pressure sensor 53 will start the fan 4 on the back of the workbench 1 through the external controller, and the airflow generated by the fan 4 will enter the interior of the workbench 1, and be discharged through the air outlet 54, and blow to the pre-forging chamber 7 and the final forging chamber 8 between the female mold 2 and the male mold 3 through different air outlets 54 at corresponding positions, so that the oxide scale inside the pre-forging chamber 7 and the final forging chamber 8 is blown out. When the forging is in any of the pre-forging chamber 7 and the final forging chamber 8, the sealing plate 55 will seal the two air outlets 54 at opposite positions of the forging. Since the female mold 2 and the male mold 3 can clean the residual oxide scale inside the pre-forging chamber 7 and the final forging chamber 8 after forging the forging, it is possible to avoid the oxide scale that is not handled in time causing local pits on the surface of the forging during subsequent forging, thereby ensuring the forging quality of the forging.

[0038] like Figures 2 to 5 and Fig.10 As shown, a reversing assembly 56 is provided on the inner upper side of the workbench 1, and the reversing assembly 56 includes a guide rod 561 fixedly connected to the lower side of the connecting plate 51, and a telescopic groove 5611 is provided on the outer side of the guide rod 561, and the number of the telescopic grooves 5611 is two, and a spring buckle 5612 is fixedly installed on the adjacent side of the two telescopic grooves 5611, and the guide rod 561 is slidably connected in the slide groove 52.

[0039] The interior of the slide 52 is rotatably connected with a rotating cylinder 562, and a guide groove 563 is provided inside the rotating cylinder 562, and the number of the guide grooves 563 is two, the two guide grooves 563 are both threaded and staggered with each other, and the lower part of the guide groove 563 is vertically provided, and the two spring buckles 5612 on the outer side of the guide rod 561 move upward and are respectively slidably connected in the two guide grooves 563, after the spring buckles 5612 slide in the guide grooves 563, the rotating cylinder 562 will rotate in the slide 52, and after the guide rod 561 moves downward, the two spring buckles 5612 are pushed into the telescopic groove 5611 by the rotating cylinder 562, and the outer side of the rotating cylinder 562 is fixedly connected with a first magnetic block 564, and the number of the first magnetic blocks 564 is two, and a rotating groove 565 is provided in the middle part of the interior of the slide 52, and the rotating groove 565 is communicated with the slide 52, and the two first magnetic blocks 564 are slidably connected in the rotating groove 565 after following the rotating cylinder 562 to rotate.

[0040] A fixed seat 566 is fixedly installed on the upper side of the workbench 1, and there are two fixed seats 566. The opposite surfaces of the two fixed seats 566 are provided with movable grooves 567. The insides of the two movable grooves 567 are slidably connected with push blocks 569. One side of the opposite surfaces of the two push blocks 569 is fixedly connected with a second magnetic block 568. The opposite magnetic poles of the two second magnetic blocks 568 repel each other, and the opposite magnetic poles of the two first magnetic blocks 564 attract each other.

[0041] A lifting assembly 57 is provided inside the fixing seat 566 and on the upper side of the working platform 1 .

[0042] By adopting the above technical solution, first, during the process of the connecting plate 51 sliding inside the slide groove 52, the guide rod 561 below it will penetrate the rotating cylinder 562 inside the slide groove 52 and move up and down inside the slide groove 52 and the rotating cylinder 562. When the connecting plate 51 is about to contact the pressure sensor 53, the two spring buckles 5612 on the outer side of the guide rod 561 will also enter the inside of the rotating cylinder 562 and enter the two guide grooves 563 respectively. As the guide rod 561 continues to move upward, the guide rod 561 drives the two spring buckles 5612 to move upward in a straight line, so that the two spring buckles 5612 inside the guide groove 563 will drive The rotating drum 562 will start to rotate inside the slide groove 52. At the same time, the two first magnetic blocks 564 on the outer side of the rotating drum 562 will also rotate inside the rotating groove 565 until the connecting plate 51 contacts the pressure sensor 53. At this time, the rotating drum 562 rotates 180 degrees, and the opposite surfaces of the two first magnetic blocks 564 are magnetically attracted to each other. At the same time, the opposite surfaces of the two second magnetic blocks 568 fixed to the push block 569 in the two fixing seats 566 are magnetically repelled. After the two first magnetic blocks 564 rotate, one of the first magnetic blocks 564 is magnetically attracted to the second magnetic block 568, and the other group of first magnetic blocks 564 is magnetically attracted to the second magnetic block 568. The first magnetic block 564 and the second magnetic block 568 are magnetically repelled, and the second magnetic block 568 is magnetically attracted to each other, which will pull the push block 569, so that the push block 569 moves toward the direction of the guide rod 561, and the second magnetic block 568, which is magnetically repelled, will move away from the first magnetic block 564 and push the push block 569 to the side away from the guide rod 561. During the movement of the push block 569 in the moving groove 567, it will contact the structure of the lifting component 57, and finally the lifting component 57 controls the blocking plate 55 to block two of the air outlets 54. When the guide rod 561 moves downward, the spring buckle 5612 is pushed by the inner wall of the guide groove 563 and retracts into the guide rod 561. The telescopic slot 5611 on the upper part of the male mold 3 is formed, so the rotating drum 562 will not rotate. Since the positions of the two first magnetic blocks 564 will be swapped each time the cylinder 101 drives the male mold 3 up and down, the magnetic poles of the two first magnetic blocks 564 will face different directions, so that one of the push blocks 569 pushes the structure of the jacking assembly 57, and the push blocks 569 pushed by each reciprocating up and down side of the male mold 3 are different, and are closely related to the forging frequency of the male mold 3 on the forging, so as to control the jacking assembly 57 to push the sealing plate 55 to block the air outlet 54, thereby further improving the chip blowing efficiency of the fan 4 on the oxide scale.

[0043] like Figure 3 and Figure 4As shown, the lifting assembly 57 includes four outlets 571 opened on the upper and lower sides of the two fixed seats 566, and the corresponding two outlets 571 are connected to the same movable groove 567. A receiving groove 572 is opened at the upper part of the workbench 1, and the number of the receiving grooves 572 is four. The four receiving grooves 572 are respectively connected to the four air outlets 54. The two upper receiving grooves 572 are respectively located below the two upper air outlets 54, and the two lower receiving grooves 572 are respectively located above the two lower air outlets 54. The upper and lower sides of the two push blocks 569 are slidably overlapped with a top block 573, and the top block 573 is slidably connected in the outlet 571. A tension spring 574 is fixedly connected to one side of the single outlet 571 close to the push block 569, and the other end of the corresponding two tension springs 574 is fixedly connected to the side of the same top block 573 close to the push block 569. The four top blocks 571 are fixedly connected to the same top block 573 close to the push block 569. 73 is divided into two groups according to the vertical column. After the rotating drum 562 drives the two first magnetic blocks 564 to rotate, one of the first magnetic blocks 564 and the second magnetic block 568 at the corresponding position are magnetically repelled, and the other first magnetic block 564 and the corresponding second magnetic block 568 are magnetically attracted, and the second magnetic block 568 that repels the first magnetic block 564 pushes the push block 569. After being pushed by the push block 569, the single group of top blocks 573 slides toward the side away from each other in the upper and lower outlets 571 respectively. After sliding in the outlet 571, the corresponding two top blocks 573 will enter the two corresponding positions of the two receiving grooves 572 respectively. The side away from the corresponding two top blocks 573 is fixedly connected with the side opposite to the corresponding two blocking plates 55. After being pushed by the push block 569, the single group of top blocks 573 pushes the two blocking plates 55 at the corresponding position from the receiving groove 572 into the air outlet 54, and the remaining two blocking plates 55 are respectively in the corresponding two receiving grooves 572.

[0044] By adopting the above technical solution, first, in the process of pushing block 569 away from guide rod 561, pushing block 569 will push the two top blocks 573 on its upper and lower sides, so that the two will respectively drive the two blocking plates 55 to move toward the positions of the two air outlets 54. When the two blocking plates 55 completely enter the air outlet 54 from the two receiving grooves 572, the air outlet 54 will be blocked by the two blocking plates 55, while the other two air outlets 54 are pulled toward guide rod 561 by the second magnetic block 568 because the pushing block 569 is pulled, so that the top block 573 is pulled by the tension spring 574, resulting in the blocking plates 55 always being in the receiving groove 572. At this time, the air outlet 54 is in an open state, and the airflow will be able to blow from the air outlet 54 to the female mold 2 and the male mold 3. At one of the pre-forging chamber 7 and the final forging chamber 8 at the corresponding position, after the cylinder 101 drives the male mold 3 to move up and down once, repeat the above steps. At this time, the other two blocking plates 55 will block the air outlet 54 at the corresponding position, and the two originally blocked air outlets 54 will be opened, and the oxide scale inside the other pre-forging chamber 7 and the final forging chamber 8 will be blown away. Since the opening of the two air outlets 54 at the corresponding positions will be controlled when the forgings are taken out of the pre-forging chamber 7 or the final forging chamber 8, the airflow generated by the fan 4 can be accurately blown away. At the same time, two of the air outlets 54 will be blocked each time, so that the wind speed of the airflow blown away by the other two air outlets 54 will increase, which further improves the efficiency of the fan 4 in blowing away the oxide scale.

[0045] like Figure 6 and Figure 7 As shown, the front sides of the female mold 2 and the male mold 3 are jointly provided with a collecting assembly 58, and the collecting assembly 58 includes a baffle 581 fixedly connected to the front side of the male mold 3, and a collecting frame 582 is fixedly connected to the front side of the female mold 2, and the opening of the collecting frame 582 faces the female mold 2, and a docking groove 583 is opened on the upper side of the collecting frame 582, and the docking groove 583 penetrates the upper side of the collecting frame 582, and the baffle 581 is inserted into the docking groove 583 after moving downward, and a support plate 585 is overlapped on the lower side of the collecting frame 582, and a bracket 584 is fixedly connected to the upper side of the support plate 585, and the upper part of the bracket 584 is slidably connected in the docking groove 583, and the baffle 581 is inserted into the docking groove 583 and squeezed into contact with the upper side of the bracket 584.

[0046] By adopting the above technical scheme, first, in the process of blowing away the air flow from the air outlet 54, the air flow at the top will blow toward the male mold 3, and the air flow at the bottom will blow toward the female mold 2. The oxide scale blown out from the pre-forging chamber 7 or the final forging chamber 8 inside the male mold 3 will be blocked by the baffle 581 and fall on the top of the female mold 2, and the oxide scale blown out from the pre-forging chamber 7 or the final forging chamber 8 inside the female mold 2 will be blown into the collection frame 582 together with the oxide scale blown out from the male mold 3, and collected by the support plate 585. When the male mold 3 and the female mold 2 are fitted together, the baffle 581 will be inserted into the collection frame 582 from the docking groove 583 above the collection frame 582, and push the bracket 584. Since the oxide scale blown out from the pre-forging chamber 7 or the final forging chamber 8 inside the male mold 3 is blocked and falls on the top of the female mold 2, and is blown into the collection frame 582 together with the oxide scale blown out from the female mold 2, it is effectively prevented that the blown oxide scale pollutes the workbench 1 and the working environment around the workbench 1.

[0047] like Figure 7 As shown, a discharge assembly 59 is provided inside the collecting frame 582 , and the discharge assembly 59 includes two limiting grooves 591 opened on the lower side of the collecting frame 582 .

[0048] The inside of the two limit grooves 591 are both slidably connected to the limit rods 592, the outside of the two limit grooves 591 are both sleeved with pressure springs 593, the bottom ends of the two pressure springs 593 are respectively fixedly connected to the inner bottom ends of the two limit grooves 591, and the bottom ends of the two limit rods 592 are fixedly connected to the upper side of the same support plate 585.

[0049] By adopting the above technical solution, first, when the baffle 581 is inserted into the docking groove 583, the bracket 584 will be pushed by the baffle 581, and the bracket 584 is fixed to the support plate 585, so that the support plate 585 will move downward, and the oxide scale on the top of the support plate 585 will gradually be exposed from the inside of the collection frame 582, and the limiting rod 592 above the support plate 585 will also slide in the limiting groove 591 inside the collection frame 582, and the oxide scale on the top of the support plate 585 is cleaned. When the male mold 3 is lifted, the pressure spring 593 inside the limiting groove 591 will push the limiting rod 592, so that the limiting rod 592 lifts the support plate 585 upward and finally fits with the bottom of the collection frame 582. After the male mold 3 and the female mold 2 are fitted, the support plate 585 with the oxide scale collected can be pushed downward, so that the oxide scale can be exposed from the inside of the collection frame 582, so as to facilitate the subsequent unified treatment of the oxide scale, and at the same time avoid the collection frame 582 being full of oxide scale and affecting the subsequent collection of the oxide scale.

[0050] like Figure 8 and Fig. 9As shown, a lubricating component 6 is provided on the lower inner side of the workbench 1 and the inner side of the mother mold 2 . The lubricating component 6 includes two storage cavities 61 opened in the inner side of the workbench 1 close to the mother mold 2 .

[0051] The interiors of the two storage chambers 61 are both connected with conduits 62, and the other ends of the two conduits 62 are connected with nozzles 63. The top ends of the two nozzles 63 are fixedly connected with top covers 64, and the two top covers 64 are slidably connected to the interior of the mother mold 2. The bottom ends of the two nozzles 63 are fixedly connected with electric push rods 67, and the two electric push rods 67 are fixedly installed on the side of the workbench 1 close to the mother mold 2. The outer sides of the two nozzles 63 are both sleeved with fixed cylinders 65, and the two fixed cylinders 65 are fixedly connected to the interior of the mother mold 2. The outer sides of the two fixed cylinders 65 are provided with grooves 66. After the nozzle 63 is pushed upward by the electric push rod 67, it drives the conduit 62 to slide in the groove 66.

[0052] By adopting the above technical solution, first, after the connecting plate 51 contacts the pressure sensor 53, the external controller will also control the electric push rod 67 inside the workbench 1 to push the nozzle 63 upward, so that the nozzle 63 gradually moves upward from the inside of the fixed cylinder 65, and the conduit 62 will also slide inside the groove 66 on the outside of the fixed cylinder 65, and the top cover 64 above the nozzle 63 will return the forging, and after the nozzle 63 is in the pre-forging chamber 7 or the final forging chamber 8 or inside, the conduit 62 will draw lubricating fluid from the storage chamber 61 and spray it into the pre-forging chamber 7 or the final forging chamber 8 through the nozzle 63. Since the nozzle 63 will also enter the pre-forging chamber 7 or the final forging chamber 8 during the process of the top cover 64 returning the forging, the lubricating fluid can be sprayed on the pre-forging chamber 7 or the final forging chamber 8 after the oxide scale is blown out, which can not only cool the inside of the pre-forging chamber 7 or the final forging chamber 8, but also facilitate the subsequent return of other forgings.

[0053] Working principle: First, when the male mold 3 is lifted upward by the cylinder 101, the connecting plate 51 above the male mold 3 will drive the guide rod 561 to move in the slide groove 52 inside the workbench 1. After the connecting plate 51 contacts the pressure sensor 53 above the slide groove 52, the fan 4 on the back of the workbench 1 is started to run, and the generated airflow will enter the interior of the workbench 1 and blow to the pre-forging chamber 7 and the final forging chamber 8 between the female mold 2 and the male mold 3 through the air outlet 54. The movement of the guide rod 561 will move up and down inside the slide groove 52 and the rotating cylinder 562, and when the connecting plate 51 is about to contact the pressure sensor 53, the two spring buckles 5612 on the outside of the guide rod 561 will also enter the rotating cylinder 562 and slide into the guide groove 563, so that the rotating cylinder 562 will start to rotate inside the slide groove 52, and drive the two first magnetic blocks 564 on its outside to rotate inside the rotating groove 565 until the connecting plate 51 contacts the pressure sensor 53. At this time, the rotating cylinder 562 rotates 180 degrees, and the guide rod 561 moves upward. When the two first magnetic blocks 564 move downward, the spring buckle 5612 is pushed by the inner wall of the guide groove 563 and retracts into the telescopic groove 5611 inside the guide rod 561, so the rotating drum 562 will not rotate. Because the opposite surfaces of the two first magnetic blocks 564 are magnetically attracted to each other, and the opposite surfaces of the two second magnetic blocks 568 fixed to the push block 569 are magnetically repelled, after the two first magnetic blocks 564 rotate, one of the first magnetic blocks 564 is magnetically attracted to the second magnetic block 568, and the other set of first magnetic blocks 564 is magnetically attracted to the second magnetic block 568. The second magnetic block 568, which is magnetically attracted, will pull the push block 569, so that the push block 569 moves toward the guide rod 561, and the second magnetic block 568, which is magnetically repelled, will move away from the first magnetic block 564 and push the push block 569 to the side away from the guide rod 561. In the process of the push block 569 moving away from the guide rod 561, the push block 569 will push the two top blocks 573 on its upper and lower sides, so that the two push blocks respectively drive the two blocking plates 55 to move toward the positions of the two air outlets 54.

[0054] When the two blocking plates 55 completely enter the air outlet 54 from the two receiving grooves 572, the air outlet 54 will be blocked by the two blocking plates 55, and the other two air outlets 54 are pulled toward the guide rod 561 by the second magnetic block 568 because the push block 569 is pulled to the guide rod 561 by the second magnetic block 568, so that the top block 573 is pulled by the tension spring 574 and slides in the outlet 571, resulting in the blocking plates 55 always being in the receiving groove 572. At this time, the air outlet 54 is in an open state, and the air flow can be blown from the air outlet 54 to one of the pre-forging chamber 7 and the final forging chamber 8 at the corresponding positions of the female mold 2 and the male mold 3. When the cylinder 101 drives the male mold 3, the air flow will be blown to the female mold 2 and the male mold 3. After the mold 3 moves up and down once, the above steps are repeated. At this time, the other two blocking plates 55 will block the air outlets 54 at the corresponding positions, and the two originally blocked air outlets 54 will be opened, and the oxide scale inside the other pre-forging chamber 7 and the final forging chamber 8 will be blown off. The oxide scale blown out from the pre-forging chamber 7 or the final forging chamber 8 inside the male mold 3 will be blocked by the baffle 581 and fall on the top of the female mold 2, and the oxide scale blown out from the pre-forging chamber 7 or the final forging chamber 8 inside the female mold 2 will be blown into the collection frame 582 together with the oxide scale blown out from the male mold 3 and will be supported. The baffle 581 is inserted into the collection frame 582 from the docking groove 583 above the collection frame 582, and the bracket 584 is pushed. The bracket 584 is pushed by the baffle 581, and the bracket 584 is fixed to the support plate 585, so that the support plate 585 will move downward. At this time, the oxide scale above the support plate 585 will gradually be exposed from the inside of the collection frame 582, and the oxide scale above the support plate 585 will be cleaned and the male mold 3 will be lifted, and the pressure spring 593 in the limit groove 591 will push the limit rod 592. , so that the limit rod 592 lifts the support plate 585 upward and finally fits with the bottom of the collection frame 582. Then the external controller controls the electric push rod 67 inside the workbench 1 to push the nozzle 63 upward, so that the nozzle 63 gradually moves upward from the inside of the fixed cylinder 65, and the conduit 62 will also slide inside the groove 66 on the outside of the fixed cylinder 65, and the top cover 64 above the nozzle 63 will withdraw the forging. After the nozzle 63 is in the pre-forging chamber 7 or the final forging chamber 8, the conduit 62 will draw lubricating fluid from the storage chamber 61 and spray it into the pre-forging chamber 7 or the final forging chamber 8 through the nozzle 63.
