Description

Technical Field

[0001] The invention belongs to the technical field of forging dies, in particular to a semi-closed forging die of a sleeve fork type. Background Art

[0002] Sleeve forks refer to a type of forgings with a specific shape and structure. This type of forging usually has the characteristics of a thick rod and a large fork opening. During the production process of sleeve forks, semi-closed molds are usually used to form the blanks. During use, the semi-closed mold can not only avoid excessive impact of the closed structure on the mold, but also increase the resistance of the open mold to the flash, thereby improving the forming efficiency of the material.

[0003] The patent with announcement number CN113547059B discloses a forging die for forgings, including a shell, the inner lower end of the shell is fixedly connected to a workbench, the upper end of the workbench is fixedly connected to a limit frame, a lower die is fixedly connected to the center of the upper end of the workbench, the inner upper end of the shell is fixedly connected to a hydraulic rod, the lower end of the hydraulic rod is fixedly connected to an upper die, an upper die demoulding mechanism is provided at the output end of the hydraulic rod, the upper die demoulding mechanism includes an upper protective cover, a lower protective cover, a rectangular opening, a first spring, a limit block, a connecting rod, a first groove, a second groove, a support rod, a push block, a third groove, a through hole, a second spring and a protrusion, the rectangular opening is opened at the output end of the hydraulic rod, and the forging can be ejected while the hydraulic rod is retracted, so that the forging will not be difficult to demould, and the oxide scale generated on the surface of the forging is timely removed when the hydraulic rod descends, which facilitates the second hammering and improves the quality of the forging.

[0004] However, the above technical solution still has the following deficiencies in practical application: After the forging is formed, although the forging can be ejected from the die cavity to achieve demolding, the ejected forging still needs to be manually taken out from between the upper die and the lower die by workers. When a large number of forgings need to be forged at one time, workers are required to frequently take out the forgings and place them in a collection container for collection, thereby increasing the labor intensity of workers. Moreover, usually, the forged forgings may have defects such as cracks. In order to prevent defective forgings from flowing into subsequent use, workers are required to visually inspect the appearance quality of the forgings and remove the defective forgings. When multiple forgings are placed in a collection container, the forgings are in a messy pile and cover each other, making it difficult to inspect the appearance quality of the forgings, affecting the inspection efficiency. When the quality of each forging is inspected after it is formed, it is not conducive to the unified comparison of multiple forgings for inspection, which also affects the inspection effect.

[0016] The beneficial effects of the present invention are as follows: 1. The semi-closed forging die of a sleeve fork type described in the present invention places the blank in the die cavity, uses a hydraulic cylinder to drive the upper die to descend, and extrude the blank in the die cavity through the upper die to fill the forming cavity with the blank to form the blank. In addition, a resistance wall is provided at the edge of the die cavity. The resistance wall can force the blank that is prone to flow to the flash in the initial forming stage to fill the cavity, while avoiding the generation of excessive forming force that causes the blank to flow to the flash, resulting in production waste or defects.

[0017] 2. The semi-closed forging die of the sleeve fork type described in the present invention utilizes a demoulding mechanism and a fork-adaptive sleeve mechanism to eject the forging from the die cavity after the forging is formed, and to hang multiple forgings in multiple placement slots on the receiving tube from left to right in sequence, thereby realizing the automatic collection of the ejected forgings, eliminating the process of workers manually collecting workpieces frequently, which is more convenient and labor-saving. Workers can check the appearance quality of each forging in turn, avoiding the situation where the forgings are concentrated and covered with each other, affecting the inspection efficiency, and multiple The forgings are in uniform and neat positions, which makes it easier for workers to inspect the appearance quality of multiple forgings by comparison, further improving the inspection effect. In addition, each forging has an independent placement area, which is not easy to slide on the receiving tube, thus avoiding the situation where the forgings slip on the receiving tube, causing the forgings to fit and cover each other, affecting the smooth progress of the inspection work. In addition, when workers inspect the forgings on the receiving tube, they can use the filling rod and the receiving tube to make the two sides of the fork hole wall pressed tightly to fix the forgings, and then drive When the receiving tube rotates, the forgings rotate with the receiving tube. The workers only need to maintain a fixed viewing angle to observe various areas of the forging surface, avoiding the need for workers to move or manually rotate the forgings on the receiving tube to achieve a comprehensive inspection of the forgings. It is more convenient and can drive each forging to rotate around the receiving tube. When the forgings rotate around the receiving tube, each position of the through-hole wall will generate friction with the outer surface of the receiving tube. At this time, the workers can observe the smoothness of the forgings when they rotate around the receiving tube to judge the quality of the through-hole wall. This avoids the situation where the worker has difficulty visually observing the through-hole wall at the fork of the forging, and thus has difficulty judging the quality of the through-hole wall at the fork of the forging, because the through-hole wall at the fork of the forging is located at the inner side. Moreover, when the inspection work is completed, the receiving tube can be driven to tilt so that the multiple forgings mounted on the receiving tube can slide into the collection box, thereby realizing the centralized collection of the forgings. Moreover, the filling rod can also be driven to move to provide support for the forgings, thereby preventing the forgings from being stuck in the placement groove without affecting the sliding of the forgings, and further ensuring the smooth collection of the forgings.

[0033] Specifically, in the prior art, after the forging is formed, although the forging can be ejected from the die cavity to realize demolding, the ejected forging still needs to be manually taken out from between the upper die 6 and the lower die 5 by the worker. When a large number of forgings need to be forged at one time, the worker needs to frequently take out the forgings and place them in a collection container for collection, thereby increasing the labor intensity of the worker. In addition, under normal circumstances, the forged forgings may have defects such as cracks. In order to prevent defective forgings from flowing into subsequent use, the worker needs to visually inspect the appearance quality of the forgings and remove the defective forgings. When multiple forgings are placed in the collection container, the forgings are in a messy pile and cover each other, making it difficult to inspect the appearance quality of the forgings, affecting the inspection efficiency. When the quality of each forging is inspected after it is formed, it is not conducive to the unified comparison of multiple forgings for inspection, which also affects the inspection effect. Therefore, in order to solve the above problems, when the present embodiment is used, after the forging is formed, the electric push rod 22 is used to drive the connecting block 33 to rise, so that the demoulding rod 34 rises and passes through the die cavity 35, and the demoulding rod 34 can eject the forging from the die cavity 35. Since the forging is a sleeve fork type, the forging has a fork and a rod. The fork of the forging will be moved out of the die cavity 35 first, and through holes of the same specification are provided on both sides of the fork, which are used for assembly and fixation with other components. Then, the motor 4 17 is used to drive the threaded rod 2 11 to rotate, so that the displacement frame 8 slides on the workbench 1. At the same time, the receiving tube 12 is aligned with the through hole of the fork, until the receiving tube 12 passes through the through hole. When the fork of the forged piece is aligned with the placement groove 19 on the receiving tube 12, the motor 10 can be used to drive the threaded rod 19 to rotate, so that the adjustment plate 36 rises, and the fork of the forged piece is just stuck in the placement groove 19, and the forged piece follows the receiving tube 12 to rise, so that the forged piece is separated from the die cavity 35, and then the above operation is repeated. , by controlling the displacement of the receiving tube 12, multiple forgings are hung in the multiple placement grooves 19 on the receiving tube 12 from left to right in turn, thereby realizing the automatic collection of the ejected forgings, eliminating the process of workers manually collecting workpieces frequently, which is more convenient and labor-saving. When a sufficient number of forgings are placed on the receiving tube 12, multiple forgings are arranged horizontally on the receiving tube 12, and workers can check the appearance quality of each forging in turn, avoiding the situation that the forgings are concentrated and covered with each other, affecting the inspection efficiency. In addition, the orientations of multiple forgings are unified and relatively neat, which is also convenient for workers to check the appearance quality of multiple forgings by comparison, further improving the inspection effect. In addition, since the spacing between the two forks of the fork mouth of the fork is the same as the width of the placement groove 19, each forging has an independent placement area and will not slip on the receiving tube 12, avoiding the situation that the forgings slip on the receiving tube 12, resulting in the forgings fitting and covering each other, affecting the smooth progress of the inspection work; Although the above method is convenient for workers to inspect the appearance quality of forgings, it is difficult for workers to inspect the other side of the forgings when they stand in a fixed area to inspect the forgings on the receiving tube 12. Therefore, workers need to move or manually rotate the forgings on the receiving tube 12 to achieve a comprehensive inspection, which is more troublesome. When the receiving tube 12 is driven to rotate to drive multiple forgings to rotate synchronously so that workers can conveniently observe the various positions of the forgings, the forgings are difficult to rotate synchronously with the receiving tube 12 due to the fitting relationship between the forgings and the placement groove 19. Therefore, in order to avoid this problem, when workers inspect the forgings on the receiving tube 12, an electric push rod 21 can be used to drive the connecting rod 2 0 rises, so that the filling rod 18 moves outward from the inner cavity of the receiving tube 12 until the filling rod 18 fits with the hole wall of the through hole at the fork of the forging, and drives the forging to rise again until the hole wall of the through hole at the fork of the forging fits with the bottom of the receiving tube 12. At this time, with the cooperation of the filling rod 18 and the receiving tube 12, the two sides of the hole wall of the fork can be pressed tightly, so that the forging can be fixed, and then the receiving tube 12 is driven to rotate by the motor 14, so that the forging can rotate with the receiving tube 12. The worker only needs to maintain a fixed viewing angle to observe various areas of the forging surface, avoiding the situation where the worker needs to move or manually rotate the forging on the receiving tube 12 to achieve a comprehensive inspection of the forging, which is more convenient; Furthermore, since the through hole wall of the fork mouth of the forging is at the inner side, it is difficult for the worker to visually observe the through hole wall, and thus it is not easy to judge the quality of the through hole wall. Therefore, in order to avoid this problem, after the fork mouth of the forging is pressed against by the filling rod 18 and the receiving tube 12, the motor five 23 can be used to drive the gear one 24 to rotate, so that the rack rod 25 is lowered until the fixed ring 27 coincides with the axis of the receiving tube 12, and then the receiving tube 12 is driven to move laterally intermittently, so that the receiving tube 12 continues to pass through the axis of the fixed ring 27. Whenever the fixed ring 27 stops moving, the paddle 31 is aligned with a forging, and the motor six 29 drives the gear two 30 to rotate. The gear ring 28 can be rotated in this way, so that the paddle 31 can make a circular motion. Although the forging is pressed tightly, when the paddle 31 contacts the rod of the forging, the rod of the forging will be pushed by the external force and rotate around the receiving tube 12. When the forging rotates around the receiving tube 12, each position of the through hole wall will produce friction with the outer surface of the receiving tube 12. At this time, the worker can observe the smoothness of the forging when it rotates around the receiving tube 12 to judge the quality of its through hole wall, thereby avoiding the situation that the through hole wall of the fork of the forging is located at the inner side, and the worker is difficult to observe the through hole wall intuitively, and then it is difficult to judge the quality of the through hole wall of the fork of the forging; When the inspection work is completed, the worker can place the collection box on one side of the workbench 1, and then use the motor 3 15 to drive the rotating plate 13 to rotate, so that the receiving tube 12 is tilted, and the multiple forgings mounted on the receiving tube 12 slide into the collection box, thereby realizing the centralized collection of the forgings. In addition, in order to prevent the forgings from being stuck in the placement groove 19 when the forgings slide down, the filling rod 18 can also be driven to move to provide support for the forgings. Without affecting the sliding of the forgings, the forgings are prevented from being stuck in the placement groove 19, thereby further ensuring the smooth collection of the forgings.

[0034] Working principle: the blank is placed in the die cavity 35, and the upper die 6 is driven down by the hydraulic cylinder 4, and the blank in the die cavity 35 is squeezed by the upper die 6, so that the blank is filled in the forming cavity to form the blank. In addition, a resistance wall 32 is set at the edge of the die cavity 35. The resistance wall 32 can force the blank that is easy to flow to the flash in the early stage of forming to fill the cavity, and at the same time avoid excessive forming force, which causes the blank to flow to the flash, resulting in production waste or defects. After the forging is formed, the electric push rod 22 is used to drive the connecting block 33 to rise, so that the demoulding rod 34 rises and passes through the die cavity 35. The demoulding rod 34 can eject the forging from the die cavity 35. Since the forging is a sleeve fork type, the fork of the forging will be moved out of the die cavity 35 first, and through holes of the same specification are provided on both sides of the fork, which are used for assembly and fixation with other components. Then, the motor 4 17 is used to drive the threaded rod 2 11 to rotate, so that the displacement frame 8 slides on the workbench 1. At the same time, the receiving tube 12 is aligned with the through hole of the fork until the receiving tube 12 passes through the through hole. When the fork of the forging is aligned with the placement groove 19 on the receiving tube 12, the threaded rod 1 9 can be driven by the motor 10 to rotate to make the adjustment When the section plate 36 rises, the fork of the forging is just stuck in the placement groove 19, and the forging follows the rise of the receiving tube 12, so that the forging is separated from the die cavity 35, and then the above operation is repeated. By controlling the displacement of the receiving tube 12, multiple forgings are hung in the multiple placement grooves 19 on the receiving tube 12 from left to right, thereby realizing the automatic collection of the ejected forgings, eliminating the process of workers manually collecting workpieces frequently, which is more convenient and labor-saving. When a sufficient number of forgings are placed on the receiving tube 12, multiple forgings are arranged horizontally on the receiving tube 12, and workers can check the outer shape of each forging in turn. The inspection of the appearance quality of the forgings can be carried out, which avoids the situation that the forgings are concentrated and covered with each other, affecting the inspection efficiency. In addition, the orientation of multiple forgings is unified and relatively neat, which is also convenient for workers to inspect the appearance quality of multiple forgings by comparison, further improving the inspection effect. In addition, since the spacing between the two forks of the fork fork is the same as the width of the placement groove 19, each forging has an independent placement area and will not slide on the receiving tube 12, avoiding the situation that the forgings slip on the receiving tube 12, resulting in the forgings fitting and covering each other, affecting the smooth progress of the inspection work;Although the above method is convenient for workers to inspect the appearance quality of forgings, it is difficult for workers to inspect the other side of the forgings when they stand in a fixed area to inspect the forgings on the receiving tube 12. Therefore, workers need to move or manually rotate the forgings on the receiving tube 12 to achieve a comprehensive inspection, which is more troublesome. When the receiving tube 12 is driven to rotate to drive multiple forgings to rotate synchronously so that workers can easily observe the various positions of the forgings, the forgings are difficult to rotate synchronously with the receiving tube 12 due to the fitting relationship between the forgings and the placement groove 19. Therefore, in order to avoid this problem, when workers inspect the forgings on the receiving tube 12, an electric push rod can be used. The first 21 drives the connecting rod 20 to rise, so that the filling rod 18 moves outward from the inner cavity of the receiving tube 12 until the filling rod 18 fits with the wall of the through hole at the fork of the forging, and drives the forging to rise again until the wall of the through hole at the fork of the forging fits with the bottom of the receiving tube 12. At this time, with the cooperation of the filling rod 18 and the receiving tube 12, the two sides of the wall of the fork through hole can be pressed tightly, so that the forging can be fixed, and then the receiving tube 12 is driven to rotate by the motor 2 14, so that the forging can rotate with the receiving tube 12. The worker only needs to maintain a fixed viewing angle to facilitate the observation of various areas on the surface of the forging, avoiding the need for the worker to move or manually rotate the forging on the receiving tube 12 before the forging can be observed. It is convenient to realize a comprehensive inspection of the forgings; and, since the through hole wall of the fork of the forging is at the inner side, it is difficult for the worker to visually observe the through hole wall, and thus it is difficult to judge the quality of the through hole wall. Therefore, in order to avoid this problem, after the fork of the forging is pressed against the filling rod 18 and the receiving tube 12, the motor 5 23 can be used to drive the gear 1 24 to rotate, so that the rack rod 25 is lowered until the fixed ring 27 coincides with the axis of the receiving tube 12, and then the receiving tube 12 is driven to move laterally intermittently, so that the receiving tube 12 continues to pass through the axis of the fixed ring 27. Whenever the fixed ring 27 stops moving, the dial plate 31 is aligned with a forging, and the motor 6 29 drives the gear 1 24 to rotate. The rotating manner of the movable gear 2 30 can rotate the gear ring 28 and make the shift plate 31 do circular motion. Although the forging is pressed tightly, when the shift plate 31 contacts the rod of the forging, the rod of the forging will be pushed by the external force and rotate around the receiving tube 12. When the forging rotates around the receiving tube 12, each position of the through hole wall will produce friction with the outer surface of the receiving tube 12. At this time, the worker can observe the smoothness of the forging when it rotates around the receiving tube 12 to judge the quality of its through hole wall, thereby avoiding the situation that the through hole wall of the fork of the forging is located at the inner position, and it is difficult for the worker to directly observe the through hole wall, and then it is difficult to judge the quality of the through hole wall of the fork of the forging;After the inspection work is finished, the worker can put the collection box on one side of the workbench 1, and then use the motor 3 15 to drive the rotating plate 13 to rotate, so that the receiving tube 12 is tilted, and the multiple forgings sleeved on the receiving tube 12 slide into the collection box, realizing the centralized collection of the forgings. In addition, in order to prevent the forgings from being stuck in the placement groove 19 when the forgings slide down, the filling rod 18 can also be driven to move to provide support for the forgings, and prevent the forgings from being stuck in the placement groove 19 without affecting the sliding of the forgings, further ensuring the smooth collection of the forgings. ;
