Description

Technical Field

[0001] The invention relates to the technical field of die forging, and in particular to a multi-directional die forging die for a shaft forging and a forming method thereof. Background Art

[0002] The forging of shaft forgings often requires the use of dies, which are generally composed of an upper die and a lower die. During forging, the metal material is placed between the upper die and the lower die, and the pressure applied by the forging machine causes the upper die to continuously impact the parts in the die hole, eventually forming a forging. However, when forging other special-shaped shaft forgings, such as cross shaft forgings, it is still necessary to extrude the shaft forging blank from both sides, which requires the use of a multi-directional die forging die.

[0003] When forging shafts nowadays, workers place the high-temperature shaft forgings in the die using special pliers, and then use pliers to take the forgings out of the lower die after forging. This makes it inconvenient for workers to load and unload the forgings, which reduces the efficiency of forging forming. In addition, manual operation is prone to errors, and high-temperature forgings pose certain safety hazards to workers, affecting the continuous processing and forging of forgings.

[0010] Preferably, a second pull rope is fixedly provided on the outer side of the push rod, and one end of the second pull rope away from the push rod passes through the main seat body and is fixedly connected to the bottom of the first baffle.

[0011] Preferably, a receiving groove is provided on the side of the loading shell, an extension guide plate is slidably connected in the receiving groove, a fourth elastic telescopic rod is provided between the extension guide plate and the inner wall of the receiving groove, a third pull rope is provided between the extension guide plate and the top plate, and a guide seat slidably connected to the third pull rope is fixed on the loading shell.

[0013] Preferably, the side forming mechanism includes a support fixed on the base, a side hydraulic cylinder arranged on the support, and an extrusion head arranged at the end of the side hydraulic cylinder, and the extrusion head is movably arranged in the forming groove.

[0014] The present invention also discloses a forming method of a multi-directional die forging forming die for a shaft forging, comprising the following steps: S1: The staff drives the upper die seat downward through the first hydraulic cylinder, so that the upper die seat approaches the lower die seat and presses down the shaft forging in the lower die seat. After the upper die seat and the lower die seat are fitted, the side hydraulic cylinder is controlled to work, and the side hydraulic cylinder drives the extrusion head to extrude and forge the shaft forging in the forming groove from the side. After the forging of the shaft forging is completed, the upper die seat is driven by the first hydraulic cylinder to move upward and reset; S2: When the first hydraulic cylinder drives the upper die seat to move upward through the top plate, the top plate pulls the extension guide plate through the third pull rope, and the extension guide plate slides out of the upper shell along the accommodating groove and approaches the lower die seat; S3: Control the second hydraulic cylinder to operate, and the plunger rod of the second hydraulic cylinder drives the lower mold body to move upward relative to the main seat body through the first elastic telescopic rod and the push rod; S4: When the push rod moves upward, the first baffle is pulled by the second pull rope, and the first baffle is forced to move downward relative to the loading shell. The first baffle no longer blocks the first shaft forging at the outlet of the loading shell, and the first shaft forging slides down along the extended guide plate. The lower mold body that moves out of the main seat body blocks the shaft forging sliding down at the loading shell. When the first baffle is forced to move downward, the second baffle is pulled by the first pull rope, and the second baffle is forced to move upward, thereby blocking the second shaft forging at the outlet of the loading shell; S5: As the second hydraulic cylinder continues to operate, the slide plate outside the push rod moves to the top of the slide groove, and the push rod cannot move further. At this time, the plunger rod of the second hydraulic cylinder squeezes the first elastic telescopic rod and continues to apply thrust to the lower mold body through the elastic telescopic plate. The force on one side of the lower mold body causes it to flip around the connection with the push rod pin shaft, and the lower mold body drives the shaft forging in the forming groove to flip; S6: As the bottom of the lower die body abuts against the top of the main seat body during the flipping, the lower die body cannot continue to flip. As the second hydraulic cylinder continues to operate, the plunger rod of the second hydraulic cylinder squeezes the elastic telescopic plate and pushes up the swing seat through the push rod, so that the swing seat flips relative to the lower die body, so that the shaft forging placed in the forming groove is pushed out, and the pushed out shaft forging falls on the unloading slide. S7: Control the plunger rod of the second hydraulic cylinder to move back, and the swing seat and the lower die body are reset under the action of their own gravity. After the lower die body shrinks back to the main seat body, the shaft forging blocked by the lower die body falls into the forming groove of the lower die seat along the extension guide plate. When the plunger rod drives the push rod to move back, the third pull rope no longer pulls the first baffle, and the first baffle and the second baffle are automatically reset. The second baffle releases the limit on the shaft forging in the loading shell, and the shaft forging slides down along the inner wall of the loading shell to the first baffle to become the first shaft forging in the loading shell; S8: Repeat steps S1-S7 to achieve continuous processing of shaft forgings in the loading shell.

[0015] Compared with the prior art, the present invention provides a multi-directional die forging forming die and a forming method for a shaft forging, which has the following beneficial effects: 1. The multi-directional die forging forming die and forming method of the shaft forging can realize automatic loading of the shaft forgings to be processed and automatic unloading of the shaft forgings after forming by setting a pushing mechanism, avoiding the problems of slow and error-prone manual loading and unloading operations, facilitating the improvement of the production and processing efficiency of forgings, and reducing the potential safety hazards caused by high-temperature forgings to workers.

[0016] 2. The multi-directional die forging forming die and forming method of the shaft forging, after the push rod pushes the lower die body out of the main seat body, the elastic telescopic plate pushes one side of the lower die body, so that the lower die body is turned over at the connection with the push rod pin shaft, so that the lower die body is in an inclined state, and then the push rod pushes the formed shaft forging which is in an inclined state with the lower die body, so that the formed shaft forging is pushed out from the forming groove and falls on the blanking slide seat, thereby improving the ejection and blanking effect of the shaft forging.

[0017] 3. The multi-directional die forging forming die and forming method of the shaft forging, when the top plate drives the upper die seat to reset and move upward, the top plate pulls the extension guide plate through the third pull rope, and the extension guide plate slides out of the loading shell along the accommodating groove and approaches the lower die seat, which can extend the range of the loading shell during non-forging forming, so that the shaft forgings sliding down in the loading shell can slide down along the extension guide plate to the forming groove, thereby improving the stability and accuracy of the feeding of the shaft forgings and reducing the error rate of the forging feeding.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] Example 1: Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 8 and Fig. 9 , a multi-directional die forging die for a shaft forging, comprising a base 1, and also comprising: The lower die base 2 is fixed on the base 1, and the lower die base 2 includes a main base body 201 and a lower die body 202 arranged in the main base body 201; A top plate 3 is arranged on the upper side of the base 1. A first hydraulic cylinder 301 for driving the top plate 3 to rise and fall is fixed on the base 1. An upper die seat 302 matching with the lower die seat 2 is arranged on the lower side of the top plate 3. Both the upper die seat 302 and the lower die seat 2 are provided with a forming groove 4 for forging shaft forgings; Side forming mechanisms, which are provided in two groups and are respectively placed on both sides of the lower die base 2; and A material pushing mechanism is arranged in the lower die seat 2 and is used to push out the shaft forging in the forming groove 4; The base 1 is also fixed with a loading shell 5 and a unloading slide 6 through the support rod 101 . The loading shell 5 and the unloading slide 6 are respectively arranged on both sides of the lower mold base 2 .

[0023] Furthermore, the side forming mechanism includes a support 16 fixed on the base 1 , a side hydraulic cylinder 161 arranged on the support 16 , and an extrusion head 162 arranged at the end of the side hydraulic cylinder 161 , and the extrusion head 162 is movably arranged in the forming groove 4 .

[0024] Specifically, the staff drives the upper die seat 302 downward by the first hydraulic cylinder 301, so that the upper die seat 302 is close to the lower die seat 2 and presses down the shaft forgings in the lower die seat 2. After the upper die seat 302 and the lower die seat 2 are fitted together, the side hydraulic cylinder 161 is controlled to work, and the side hydraulic cylinder 161 drives the extrusion head 162 to extrude and forge the shaft forgings in the forming groove 4 from the side. After the forging of the shaft forgings is completed, the upper die seat 302 is driven by the first hydraulic cylinder 301 to move up and reset, and then the pushing mechanism is controlled to work to push the shaft forgings in the forming groove 4 into the unloading chute. In this process, the shaft forgings in the loading shell 5 are automatically loaded and replenished. By setting the pushing mechanism, automatic loading and unloading of the shaft forgings to be processed and automatic unloading of the shaft forgings after forming can be realized, avoiding the problem that manual loading and unloading operations are slow and prone to errors, facilitating the improvement of the production and processing efficiency of forgings, and reducing the safety hazards caused by high-temperature forgings to staff.

[0025] Example 2: Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 , a multi-directional forging forming die for a shaft forging. On the basis of Example 1, further, a main base body 201 is provided with a movable groove 7 for the movement of a lower die body 202, and a support platform 701 for supporting the lower die body 202 is fixedly provided in the movable groove 7. The pushing mechanism includes a second hydraulic cylinder 8 fixedly mounted on a base 1, a first elastic telescopic rod 801 arranged on the top of the second hydraulic cylinder 8, and a push rod 802 arranged on the top of the first elastic telescopic rod 801. The top side of the push rod 802 is rotatably connected to the lower die body 202 through a pin shaft.

[0026] Furthermore, a slide plate 8021 is fixedly provided on the outer side of the push rod 802 , and a slide groove 702 for the slide plate 8021 to slide is provided on the inner wall of the movable groove 7 .

[0027] Furthermore, the pushing mechanism also includes a connecting plate 9 fixedly connected to the plunger rod 803 of the second hydraulic cylinder 8, an elastic telescopic plate 901 arranged on the top of the connecting plate 9, and a push rod 902 fixedly connected to the connecting plate 9 and placed in the elastic telescopic plate 901. The end of the elastic telescopic plate 901 away from the connecting plate 9 is movably abutted against the bottom of the lower mold body 202. A swing seat 10 movably abuts against the push rod 902 is provided in the lower mold body 202 through a pin shaft, and a curved surface matching the inner wall of the forming groove 4 is provided on the swing seat 10.

[0028] Specifically, after the forging of the shaft forging is completed, the upper die seat 302 is driven by the first hydraulic cylinder 301 to move up and reset, and the second hydraulic cylinder 8 is controlled to operate. The plunger rod 803 of the second hydraulic cylinder 8 drives the lower die body 202 to move up relative to the main seat body 201 through the first elastic telescopic rod 801 and the push rod 802. As the second hydraulic cylinder 8 continues to operate, the slide plate 8021 on the outside of the push rod 802 moves to the top of the slide groove 702, and the push rod 802 cannot move further. At this time, the plunger rod 803 of the second hydraulic cylinder 8 squeezes the first elastic telescopic rod 801 and continues to apply thrust to the lower die body 202 through the elastic telescopic plate 901. The force on one side of the lower die body 202 causes it to flip around the pin connection with the push rod 802. The lower die body 202 drives the shaft forgings in the forming groove 4 to flip. As the lower die body 202 flips, the bottom and the main seat The top of the body 201 abuts against the lower mold body 202, and the lower mold body 202 cannot continue to flip over. As the second hydraulic cylinder 8 continues to operate, the plunger rod 803 of the second hydraulic cylinder 8 squeezes the elastic telescopic plate 901 and pushes up the swing seat 10 through the push rod 902, so that the swing seat 10 flips relative to the lower mold body 202, so that the shaft forgings placed in the forming groove 4 are pushed out, and the pushed out shaft forgings fall on the unloading slide 6, avoiding direct pushing of the formed shaft forgings in the lower mold body 202. The shaft forgings cannot be smoothly pushed to one side because one side is stuck in the forming groove 4. By making the lower mold body 202 in an inclined state and then making the push rod 902 push the formed shaft forgings that are in an inclined state with the lower mold body 202, it is convenient for the formed shaft forgings to be pushed out from the forming groove 4 and fall on the unloading slide 6, thereby ensuring the ejection and unloading effect of the shaft forgings.

[0029] Example 3: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Fig.10, a multi-directional forging die for shaft forgings. On the basis of Example 2, further, a first baffle 11 and a second baffle 12 are slidably connected in a loading shell 5, and the first baffle 11 and the second baffle 12 are both movably opposed to the shaft forgings. A second elastic telescopic rod 111 is arranged between the first baffle 11 and the bottom wall of the loading shell 5, and a third elastic telescopic rod 121 is arranged between the second baffle 12 and the bottom wall of the loading shell 5. A first pull rope 122 is fixedly provided at the bottom of the first baffle 11, and an end of the first pull rope 122 away from the first baffle 11 passes through the loading shell 5 and is connected to the second baffle 12.

[0030] Furthermore, a second pull rope 13 is fixedly provided on the outer side of the push rod 802 , and one end of the second pull rope 13 away from the push rod 802 passes through the main seat body 201 and is fixedly connected to the bottom of the first baffle 11 .

[0031] Specifically, when the pushing mechanism is working, the push rod 802 moves up and pulls the first baffle 11 through the second pull rope 13. The first baffle 11 is forced to move downward relative to the loading shell 5. The first baffle 11 no longer blocks the first shaft forging at the outlet of the loading shell 5. The lower mold body 202 moved out of the main seat body 201 will block the shaft forging sliding down from the loading shell 5. When the first baffle 11 is forced to move downward, the second baffle 12 is pulled by the first pull rope 122. The second baffle 12 is forced to move upward, thereby blocking the second shaft forging at the outlet of the loading shell 5. The shaft forgings are blocked to prevent the shaft forgings in the loading shell 5 from sliding down together. After the formed shaft forgings in the forming groove 4 are pushed out, when the plunger rod 803 drives the push rod 802 to move back, the third pull rope 15 no longer pulls the first baffle 11, and the first baffle 11 and the second baffle 12 are automatically reset. The second baffle 12 releases the limit on the shaft forgings in the loading shell 5, and the shaft forgings slide down along the inner wall of the loading shell 5 to the first baffle 11 to become the first shaft forging in the loading shell 5, preparing for reloading of the loading shell 5.

[0032] Example 4: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Fig.11 , a multi-directional die forging mold for a shaft forging. On the basis of Example 3, further, a receiving groove 14 is opened on the side of the loading shell 5, and an extension guide plate 141 is slidably connected in the receiving groove 14, a fourth elastic telescopic rod 142 is arranged between the extension guide plate 141 and the inner wall of the receiving groove 14, a third pull rope 15 is arranged between the extension guide plate 141 and the top plate 3, and a guide seat 151 slidably connected to the third pull rope 15 is fixed on the loading shell 5.

[0033] Specifically, after the forging of the shaft forging is completed, the upper die seat 302 is driven upward and reset by the first hydraulic cylinder 301. When the first hydraulic cylinder 301 drives the upper die seat 302 to move upward through the top plate 3, the top plate 3 pulls the extension guide plate 141 through the third pull rope 15. The extension guide plate 141 slides out of the loading shell 5 along the accommodating groove 14 and approaches the lower die seat 2. The range of the loading shell 5 can be extended during the non-forging period, so that the shaft forgings sliding down in the loading shell 5 can slide down along the extension guide plate 141 to the forming groove 4, thereby improving the stability and accuracy of loading of shaft forgings and reducing the error rate of forging loading.

[0034] Example 5: Reference Figure 5 , Figure 6 and Fig. 9 A multi-directional forging die for a shaft forging, based on Example 4, further, an arc baffle 2021 is fixedly provided at the bottom of the lower die body 202, and the arc baffle 2021 is movably offset from the shaft forging sliding down the discharge port of the upper shell 5.

[0035] Specifically, when the pushing mechanism is working, the lower mold body 202 moves upward relative to the main seat body 201, and can block the shaft forgings sliding down from the upper shell 5. As the lower mold body 202 moves out of the main seat body 201 and flips over, the arc-shaped baffle 2021 can continue to block the shaft forgings to prevent the shaft forgings from moving to the lower side of the flipped lower mold body 202 and affecting the reset and downward movement of the lower mold body 202.

[0036] The present invention also discloses a forming method of a multi-directional die forging forming die for a shaft forging, comprising the following steps: S1: The staff drives the upper die seat 302 downward through the first hydraulic cylinder 301, so that the upper die seat 302 approaches the lower die seat 2 and presses down the shaft forging in the lower die seat 2. After the upper die seat 302 and the lower die seat 2 are fitted together, the side hydraulic cylinder 161 is controlled to work, and the side hydraulic cylinder 161 drives the extrusion head 162 to extrude and forge the shaft forging in the forming groove 4 from the side. After the shaft forging is forged, the upper die seat 302 is driven by the first hydraulic cylinder 301 to move upward and reset; S2: When the first hydraulic cylinder 301 drives the upper die base 302 to move upward through the top plate 3, the top plate 3 pulls the extension guide plate 141 through the third pull rope 15, and the extension guide plate 141 slides out of the upper shell 5 along the accommodating groove 14 and approaches the lower die base 2; S3: Control the second hydraulic cylinder 8 to operate, and the plunger rod 803 of the second hydraulic cylinder 8 drives the lower mold body 202 to move upward relative to the main seat body 201 through the first elastic telescopic rod 801 and the push rod 802; S4: When the push rod 802 moves upward, the first baffle 11 is pulled by the second pull rope 13, and the first baffle 11 is forced to move downward relative to the loading shell 5. The first baffle 11 no longer blocks the first shaft forging at the outlet of the loading shell 5. The first shaft forging slides down along the extended guide plate 141, and the lower mold body 202 that moves out of the main seat body 201 blocks the shaft forging sliding down at the loading shell 5. When the first baffle 11 is forced to move downward, the second baffle 12 is pulled by the first pull rope 122, and the second baffle 12 is forced to move upward, thereby blocking the second shaft forging at the outlet of the loading shell 5; S5: As the second hydraulic cylinder 8 continues to operate, the slide plate 8021 outside the push rod 802 moves to the top of the slide groove 702, and the push rod 802 cannot move further. At this time, the plunger rod 803 of the second hydraulic cylinder 8 squeezes the first elastic telescopic rod 801 and continues to apply thrust to the lower mold body 202 through the elastic telescopic plate 901. The force on one side of the lower mold body 202 causes it to flip around the pin connection with the push rod 802, and the lower mold body 202 drives the shaft forging in the forming groove 4 to flip; S6: As the bottom of the lower die body 202 abuts against the top of the main seat body 201 during the flipping, the lower die body 202 cannot continue to flip. As the second hydraulic cylinder 8 continues to operate, the plunger rod 803 of the second hydraulic cylinder 8 squeezes the elastic telescopic plate 901 and pushes up the swing seat 10 through the push rod 902, so that the swing seat 10 flips relative to the lower die body 202, so that the shaft forging placed in the forming groove 4 is pushed out, and the pushed out shaft forging falls on the unloading slide 6; S7: Control the plunger rod 803 of the second hydraulic cylinder 8 to move back, and the swing seat 10 and the lower die body 202 are reset under the action of their own gravity. After the lower die body 202 shrinks back to the main seat body 201, the shaft forging blocked by the lower die body 202 falls into the forming groove 4 of the lower die seat 2 along the extended guide plate 141. When the plunger rod 803 drives the push rod 802 to move back, the third pull rope 15 no longer pulls the first baffle 11, and the first baffle 11 and the second baffle 12 are automatically reset. The second baffle 12 releases the limit on the shaft forging in the loading shell 5, and the shaft forging slides down along the inner wall of the loading shell 5 to the first baffle 11 to become the first shaft forging in the loading shell 5; S8: Repeat steps S1-S7 to achieve continuous processing of the shaft forgings in the loading shell 5.

10. A forming method of a multi-directional forging die for a shaft forging as claimed in claim 9, characterized in that: The following steps are involved: S1: A staff member drives the upper die seat (302) to move downward by means of a first hydraulic cylinder (301), so that the upper die seat (302) approaches the lower die seat (2) and presses down the shaft forging in the lower die seat (2). After the upper die seat (302) and the lower die seat (2) are in contact with each other, the staff member controls the side hydraulic cylinder (161) to operate, and the side hydraulic cylinder (161) drives the extrusion head (162) to perform extrusion forging on the shaft forging in the forming groove (4) from the side. After the forging of the shaft forging is completed, the staff member drives the upper die seat (302) to move upward and reset by means of the first hydraulic cylinder (301); S2: When the first hydraulic cylinder (301) drives the upper die base (302) to move upward via the top plate (3), the top plate (3) pulls the extension guide plate (141) via the third pull rope (15), and the extension guide plate (141) slides out of the upper shell (5) along the accommodating groove (14) and approaches the lower die base (2); S3: controlling the second hydraulic cylinder (8) to operate, so that the plunger rod (803) of the second hydraulic cylinder (8) drives the lower mold body (202) to move upward relative to the main seat body (201) through the first elastic telescopic rod (801) and the push rod (802); S4: When the push rod (802) moves upward, the first baffle (11) is pulled by the second pull rope (13), and the first baffle (11) is forced to move downward relative to the loading shell (5). The first baffle (11) no longer blocks the first shaft forging at the outlet of the loading shell (5). The first shaft forging slides down along the extended guide plate (141), and the lower mold body (202) that moves out of the main seat body (201) blocks the shaft forging sliding down at the loading shell (5). When the first baffle (11) is forced to move downward, the second baffle (12) is pulled by the first pull rope (122), and the second baffle (12) is forced to move upward, thereby blocking the second shaft forging at the outlet of the loading shell (5); S5: As the second hydraulic cylinder (8) continues to operate, the slide plate (8021) outside the push rod (802) moves to the top of the slide groove (702), and the push rod (802) cannot move further. At this time, the plunger rod (803) of the second hydraulic cylinder (8) squeezes the first elastic telescopic rod (801) and continues to apply thrust to the lower mold body (202) through the elastic telescopic plate (901). The force on one side of the lower mold body (202) causes it to flip around the pin connection with the push rod (802), and the lower mold body (202) drives the shaft forging in the forming groove (4) to flip; S6: As the bottom of the lower mold body (202) abuts against the top of the main seat body (201) during the flipping, the lower mold body (202) cannot continue to flip. As the second hydraulic cylinder (8) continues to operate, the plunger rod (803) of the second hydraulic cylinder (8) squeezes the elastic telescopic plate (901) and pushes the swing seat (10) upward through the push rod (902), so that the swing seat (10) flips relative to the lower mold body (202), so that the shaft forging placed in the molding groove (4) is pushed out, and the pushed out shaft forging falls on the blanking slide (6); S7: Control the plunger rod (803) of the second hydraulic cylinder (8) to move back, and the swing seat (10) and the lower die body (202) are reset under the action of their own gravity. After the lower die body (202) shrinks back to the main seat body (201), the shaft forging blocked by the lower die body (202) falls into the forming groove (4) of the lower die seat (2) along the extension guide plate (141). When the plunger rod (803) drives the push rod (802) to move back, the third pull rope (15) no longer pulls the first baffle (11), and the first baffle (11) and the second baffle (12) are automatically reset. The second baffle (12) releases the limit on the shaft forging in the loading shell (5), and the shaft forging slides down along the inner wall of the loading shell (5) to the first baffle (11) to become the first shaft forging in the loading shell (5); S8: Repeat steps S1-S7 to achieve continuous processing of the shaft-type forgings inside the loading shell (5).
