Description

TECHNICAL FIELD

[0001] The present application relates to the field of forging technology, and in particular to a forging die and a forging equipment. BACKGROUND

[0002] In the related art, in order to facilitate the demolding of the workpiece, the technical personnel will spray lubricating graphite in the forging die. The forging die is provided with a positioning mechanism for positioning the workpiece to be processed to prevent displacement.

[0003] However, the existing positioning mechanism is usually arranged in the forging die in a telescopic manner along a direction parallel to the forging direction. When the lubricating graphite is sprayed, the graphite will cover the matching surface of the positioning mechanism. Over a long period of time, the matching surface of the positioning mechanism is easily covered with lubricating graphite, causing the problem of jamming or sticking, which damages the forging die or the workpiece. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a forging die and a forging equipment to solve the technical problem that the existing positioning mechanism is prone to jamming and damages the forging die.

[0005] An embodiment of the present application provides a forging die. The forging die comprises a lower die assembly, an upper die assembly, and a point positioning assembly. The lower die assembly is provided with a forming area configured to carry a workpiece. The upper die assembly is configured to be movable relative to the lower die assembly along a first direction, and is used to press the workpiece located in the forming area. The positioning assembly comprises a guide seat and a telescopic piece. The guide seat is installed on the lower die assembly. The telescopic piece comprises a connecting segment and a bearing segment. The connecting segment is slidingly installed on the guide seat along a second direction, and the bearing segment is connected with the connecting segment. The second direction intersects the first direction. The telescopic piece is configured to be movable to a first position or a second position. When the telescopic piece is in the first position, the bearing segment is located outside the guide seat and extends into the forming area to fix the workpiece. When the telescopic piece is in the second position, the bearing segment is located outside the guide seat and moves out of the forming area to release the fixation of the workpiece.

[0006] In the above-mentioned forging die, the positioning assembly is arranged outside the forming area, and the positioning assembly positions the workpiece along a direction intersecting the forging direction, which is beneficial to reduce the risk of the lubricating graphite adhering to the connecting segment of the telescopic piece. At the same time, the bearing segment of the telescopic piece is always located outside the guide seat, and does not need to be slidingly matched with the guide seat. Therefore, the risk of the positioning assembly being jammed or stuck can be reduced, and the quality of the workpiece pressing and the service life of the forging die can be improved.

[0007] In at least one embodiment, the positioning assembly further comprises a pushing piece installed on the upper die assembly. The pushing piece is configured to drive the telescopic piece to move to the second position when the upper die assembly moves relative to the lower die assembly.

[0008] In the above embodiment, the pushing member can be driven by the upper die assembly to drive the telescopic member to move to the second position, and the technician does not need to add an additional driving member such as a telescopic cylinder or a telescopic motor, thereby saving production cost.

[0009] In at least one embodiment, the positioning assembly further comprises a transmission member rotatably installed on the guide seat and connected with the connecting segment, and the transmission member is configured to rotate under the action of the pushing member and drive the telescopic member to move to the second position.

[0010] In the above embodiment, by providing the transmission member, the movement stroke of the telescopic member can be increased on the basis of maintaining the original movement stroke of the pushing member. On the one hand, it is beneficial to improve the flexibility of the forging die to adapt to different types of workpieces, and the technician can select a suitable transmission member according to different workpieces. On the other hand, it can increase the operation time for other processes that need to be completed during the movement of the telescopic member to the second position, such as heating the material.

[0011] In at least one embodiment, the guide seat is provided with a guide hole in the second direction, and the connecting segment is slidingly inserted into the guide hole.

[0012] In the above embodiment, by providing the guide hole, it is beneficial to reduce the risk of external pollutants (such as dust, debris, etc.) falling and hindering the relative sliding of the telescopic member and the guide seat, improve the stability of the sliding cooperation between the telescopic member and the guide seat, and make the relative sliding between the telescopic member and the guide seat smoother.

[0013] In at least one embodiment, the guide seat is provided with a first slot in the second direction, the first slot is communicated with the guide hole, and the transmission member is provided with a second slot. The connecting segment is provided with a matching part which is inserted into the first slot and the second slot. The matching part is configured to slide along the first slot and the second slot when the pushing member drives the transmission member to rotate, and drive the telescopic member to move to the second position.

[0014] In the above embodiment, when the pushing member drives the transmission member to rotate, the matching part can slide along the first slot and the second slot to drive the telescopic member to move to the second position. By providing the first slot and the second slot, it is beneficial to ensure that the telescopic member accurately slides to the second position in the second direction, reduce the risk of movement interference between the transmission member and the telescopic member, and thereby protect the forging die.

[0015] In at least one embodiment, the positioning assembly further comprises a rolling member installed on the transmission member. The rolling member is configured to roll along the contact surface of the pushing member when the pushing member drives the transmission member to rotate.

[0016] In the above embodiment, by providing the rolling member, the sliding friction between the transmission member and the pushing member can be converted into rolling friction. Compared with sliding friction, the rolling friction has smaller friction, which helps to reduce the wear of the pushing member and the transmission member and prolong the service life.

[0017] In at least one embodiment, the upper die assembly is provided with an avoiding groove configured to avoid the abutting section during movement of the telescopic piece to the first position or the second position.

[0018] In the above embodiment, the avoiding groove can avoid the abutting section of the telescopic piece during relative movement of the upper die assembly and the lower die assembly along the first direction and movement of the telescopic piece along the second direction to the first position or the second position, so as to reduce the risk of interference between the upper die assembly and the telescopic piece, thereby further improving the service life of the forging die.

[0019] In at least one embodiment, the positioning assembly further comprises a first elastic piece mounted in the guide hole, one end of the first elastic piece being connected to the guide seat and the other end being connected to the connecting section. The telescopic piece is configured to move to the first position under the action of the first elastic piece.

[0020] In the above embodiment, when the upper die assembly moves away from the lower die assembly along the first direction, the telescopic piece moves to the first position under the elastic force of the first elastic piece. By providing the first elastic piece, automatic resetting of the telescopic piece can be achieved, which helps to improve the degree of automation of the forging die and improve the user experience.

[0021] In at least one embodiment, the positioning assembly further comprises a second elastic piece, one end of the second elastic piece being connected to the transmission piece and the other end being connected to the guide seat. The second elastic piece is configured to drive the transmission piece to rotate to return to the initial position.

[0022] In the above embodiment, when the upper die assembly moves away from the lower die assembly along the first direction, the upper die assembly drives the pushing piece to move away from the transmission piece, and the transmission piece returns to the initial position under the elastic force of the second elastic piece to wait for the next work. By providing the second elastic piece, automatic resetting of the transmission piece can be achieved, which helps to further improve the degree of automation of the forging die and improve the user experience.

[0023] An embodiment of the present application provides a forging equipment. The forging equipment comprises a driving mechanism and a forging die as described in any of the above embodiments, the forging die being connected to the driving mechanism, and the driving mechanism being configured to drive the upper die assembly and the lower die assembly to move relatively along the first direction.

[0035] The following detailed description will further describe the present application with reference to the above mentioned figures. DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0038] The present application provides a forging die. The forging die comprises a lower die assembly, an upper die assembly and a point positioning assembly. The lower die assembly is provided with a forming area, the forming area is configured to carry a workpiece, and lubricating graphite is sprayed on the forming area. The upper die assembly is configured to be movable relative to the lower die assembly along a first direction, and the upper die assembly and the lower die assembly jointly compress the workpiece located in the forming area. The positioning assembly comprises a guide seat and a telescopic piece, and the guide seat is installed on the lower die assembly. The telescopic piece comprises a connecting segment and a bearing segment, the connecting segment is slidingly installed on the guide seat along a second direction, and the bearing segment is connected with the connecting segment, and the second direction intersects the first direction. The telescopic piece is configured to be movable to a first position or a second position. When the telescopic piece is in the first position, the bearing segment is located outside the guide seat and extends into the forming area to fix the workpiece. When the telescopic piece is in the second position, the bearing segment is located outside the guide seat and moves out of the forming area to release the fixation of the workpiece.

[0039] In the above-mentioned forging die, the positioning assembly is arranged outside the forming area, and the positioning assembly positions the workpiece along the intersecting forging direction, which is beneficial to reduce the risk of lubricating graphite adhering to the connecting segment of the telescopic piece. At the same time, the bearing segment in the telescopic piece is always located outside the guide seat, and does not need to be slidingly matched with the guide seat. Thus, the risk of the positioning assembly being jammed or stuck can be reduced, and the quality of workpiece compression and the service life of the forging die are improved.

[0040] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0041] In the present embodiment, the first direction is defined to intersect the second direction. The first direction is the direction parallel to X in the figure, and the second direction is the direction parallel to Y in the figure. For the convenience of referring to the figure, the first direction is denoted as "first direction X" hereinafter, and the second direction is denoted as "second direction Y".

[0042] An embodiment of the present application provides a forging die 10. As shown in Figures 1 to 3 The forging die 10 comprises a lower die assembly 11, an upper die assembly 12 and a positioning assembly 13. The lower die assembly 11 is provided with a forming area 111 configured to carry a workpiece (not shown in the figure). The workpiece can be a plate-shaped workpiece, a rod-shaped workpiece or the like.

[0043] The upper die assembly 12 is configured to be movable relative to the lower die assembly 11 along a first direction X, and the upper die assembly 12 and the lower die assembly 11 jointly compress the workpiece located in the forming area 111. Understandably, when the workpiece needs to be forged, the user first places the workpiece on the forming area 111 of the lower die assembly 11, and then the upper die assembly 12 moves along the first direction X towards the lower die assembly 11, and the upper die assembly 12 and the lower die assembly 11 jointly compress the workpiece to obtain a target workpiece.

[0044] After the forging is completed, the upper die assembly 12 moves along the first direction X away from the lower die assembly 11, and the upper die assembly 12 and the lower die assembly 11 are separated, and the user can take the target workpiece out of the forming area 111.

[0045] In the embodiment, the lubricating graphite is sprayed on the forming area 111, which is beneficial to reduce the risk of adhesion of the workpiece to the upper die assembly 12 and the lower die assembly 11, and facilitate the demolding of the workpiece. It is worth noting that the spraying of the lubricating graphite is performed when the upper die assembly 12 and the lower die assembly 11 are in a separated state.

[0046] For example, the user sprays the lubricating graphite along the first direction X through an external liquid spraying pipe to uniformly spray the lubricating graphite on the forming area 111. In other embodiments, other suitable spraying methods can also be used, which are not limited in the present application.

[0047] In the embodiment, as shown in Figure 4 and Figure 5 The positioning assembly 13 comprises a guide seat 131 and a telescopic piece 132, and the guide seat 131 is installed on the lower die assembly 11. The telescopic piece 132 comprises a connecting segment 1322 and an abutting segment 1321, the connecting segment 1322 is slidingly installed on the guide seat 131 along a second direction Y, and the abutting segment 1321 is connected with the connecting segment 1322.

[0048] The telescopic piece 132 is configured to be movable to a first position or a second position. When the telescopic piece 132 is in the first position, the abutting segment 1321 is located outside the guide seat 131 and extends into the forming area 111 to fix the workpiece. When the telescopic piece 132 is in the second position, the abutting segment 1321 is located outside the guide seat 131 and moves out of the forming area 111 to release the fixation of the workpiece.

[0049] For example, in the initial state, the upper die assembly 12 and the lower die assembly 11 are in a separated state, and the workpiece is placed in the forming area 111 of the lower die assembly 11. The telescopic piece 132 is in the first position, and the abutting segment 1321 is located outside the guide seat 131 and extends into the forming area 111 to fix the workpiece.

[0050] When the workpiece needs to be forged, the upper die assembly 12 and the lower die assembly 11 move towards each other along the first direction X, and the upper die assembly 12 and the lower die assembly 11 jointly press the workpiece. At this time, the telescopic piece 132 moves to the second position, and the abutting segment 1321 is located outside the guide seat 131 and moves out of the forming area 111 to release the fixation of the workpiece.

[0051] After the forging is completed, the upper die assembly 12 and the lower die assembly 11 move away from each other along the first direction X, and the upper die assembly 12 and the lower die assembly 11 return to the initial position (specifically, the position when the upper die assembly 12 and the lower die assembly 11 are in a separated state). At this time, the telescopic piece 132 moves to the first position. The abutting segment 1321 is located in the forming area 111, and the abutting segment 1321 presses the workpiece. In this way, the upper die assembly 12, the lower die assembly 11 and the telescopic piece 132 are cyclically moved.

[0052] In the forging die 10 of the present application, the positioning assembly 13 is arranged outside the forming area 111, and the positioning assembly 13 positions the workpiece along the second direction Y, which intersects with the movement direction (specifically, the first direction X) of the upper die assembly 12 and the lower die assembly 11. In other words, the abutting segment 1321 of the telescopic piece 132 extends into the forming area 111, and the connecting segment 1322 of the telescopic piece 132 is located outside the forming area 111.

[0053] Therefore, when the user sprays the lubricating graphite into the forming area 111, the lubricating graphite can only adhere to the abutting segment 1321 of the telescopic piece 132, and it is difficult to adhere to the connecting segment 1322 of the telescopic piece 132. At the same time, during the movement of the telescopic piece 132 along the second direction Y to the first position or the second position, the abutting segment 1321 in the telescopic piece 132 is always located outside the guide seat 131, and does not need to be in sliding cooperation with the guide seat 131. In this way, the risk of jamming or sticking of the positioning assembly 13 can be reduced, and the quality of workpiece pressing and the service life of the forging die 10 can be improved.

[0054] It should be further noted that, compared with the existing positioning mechanism which is arranged in the forging direction through the forging die, the forging die 10 of the present application does not need to punch the lower die assembly 11, thereby improving the structural strength of the lower die assembly 11 and prolonging the service life thereof.

[0055] In the present embodiment, as shown in FIG. 1, the telescopic piece 132 is arranged in the forming area 111 of the lower die assembly 11. Figures 1 to 3As shown, the positioning assembly 13 further comprises a pushing member 133, which is installed on the upper die assembly 12 and is configured to drive the telescopic member 132 to move to the second position when the upper die assembly 12 moves relative to the lower die assembly 11.

[0056] As can be understood, when the upper die assembly 12 moves in the first direction X towards the lower die assembly 11, the upper die assembly 12 can drive the pushing member 133 to move, and the pushing member 133 drives the telescopic member 132 to move to the second position in the second direction Y to release the fixation of the workpiece.

[0057] Through the arrangement of the pushing member 133, the user does not need to additionally add a driving member to drive the telescopic member 132 to move, such as a telescopic cylinder, a telescopic motor, etc., thereby saving production cost.

[0058] In the embodiment, as shown in Figure 1 , Figure 5 and Figure 6 , the positioning assembly 13 further comprises a transmission member 134, which is rotatably installed on the guide seat 131 and connected with the connecting segment 1322, and is configured to rotate under the action of the pushing member 133 and drive the telescopic member 132 to move to the second position.

[0059] As can be understood, when the upper die assembly 12 moves in the first direction X towards the lower die assembly 11, the upper die assembly 12 drives the pushing member 133 to move, the pushing member 133 drives the transmission member 134 to rotate, and the transmission member 134 drives the telescopic member 132 to move to the second position in the second direction Y to release the fixation of the workpiece.

[0060] Through the arrangement of the transmission member 134, the movement stroke of the telescopic member 132 can be increased on the basis of keeping the original movement stroke of the pushing member 133. In this way, on the one hand, it is beneficial to improve the flexibility of the forging die 10 and adapt to different types of workpieces, and the technical personnel can select a suitable transmission member 134 according to different workpieces. On the other hand, it can increase the operation time for other processes that need to be completed in the process of moving the telescopic member 132 to the second position, such as heating the material.

[0061] In the embodiment, the pushing member 133 drives the transmission member 134 to rotate through friction. For example, the upper die assembly 12 drives the pushing member 133 to move in the first direction X towards the lower die assembly 11, and the pushing member 133 will first contact the end surface of the transmission member 134. At this time, the transmission member 134 will exert an action force towards the pushing member 133. As the pushing member 133 continues to move, the pushing member 133 can slide relative to the transmission member 134, and can drive the transmission member 134 to rotate through the friction between the transmission member 134 and the pushing member 133.

[0062] In other embodiments, the pushing member 133 can also directly press the transmission member 134 to drive the transmission member 134 to rotate. The present application does not make any limitation in this regard, and those skilled in the art can select according to the actual situation.

[0063] In the present embodiment, as shown in Figure 1 and Figure 6 , the guide seat 131 is provided with a guide hole 1311 in the second direction Y, and the connecting segment 1322 is slidingly inserted into the guide hole 1311. Through the arrangement of the guide hole 1311, it is beneficial to reduce the risk of hindering the relative sliding of the telescopic member 132 and the guide seat 131 due to the falling of external contaminants (such as dust, debris, etc.), improve the stability of the sliding cooperation between the telescopic member 132 and the guide seat 131, and make the relative sliding between the telescopic member 132 and the guide seat 131 more smooth.

[0064] In other embodiments, the guide seat 131 and the connecting segment 1322 can also be connected by other suitable sliding structures, such as the guide seat 131 being provided with a sliding rail (not shown in the figure), and the connecting segment 1322 being provided with a sliding block (not shown in the figure), and the sliding block being slidingly installed in the sliding rail. The present application does not make any limitation in this regard, and those skilled in the art can select according to the actual situation.

[0065] In the present embodiment, as shown in Figure 5 and Figure 6 , the guide seat 131 is provided with a first groove 1312 in the second direction Y, the first groove 1312 is in communication with the guide hole 1311, and the transmission member 134 is provided with a second groove 1341. The connecting segment 1322 is provided with a matching part 1342, and the matching part 1342 is arranged to pass through the first groove 1312 and the second groove 1341.

[0066] The matching part 1342 is configured to slide along the first groove 1312 and the second groove 1341 when the pushing member 133 drives the transmission member 134 to rotate, and drive the telescopic member 132 to move to the second position. It can be understood that when the pushing member 133 drives the transmission member 134 to rotate, the matching part 1342 can slide along the first groove 1312 and the second groove 1341 to drive the telescopic member 132 to move to the second position. Through the arrangement of the first groove 1312 and the second groove 1341, it is beneficial to ensure that the telescopic member 132 accurately slides to the second position in the second direction Y, reduce the risk of motion interference between the transmission member 134 and the telescopic member 132, and thus protect the forging die 10.

[0067] In the present embodiment, as shown in Figure 3 , Figure 5 and Figure 6 , the positioning assembly 13 further comprises a rolling member 135, and the rolling member 135 is installed on the transmission member 134. The rolling member 135 is configured to roll along the contact surface of the pushing member 133 when the pushing member 133 drives the transmission member 134 to rotate.

[0068] Understandably, when the upper die assembly 12 drives the pusher 133 to move in the first direction X towards the lower die assembly 11, the pusher 133 will be in contact with the rolling piece 135 and drive the transmission piece 134 to rotate through friction. Wherein, when the pusher 133 drives the transmission piece 134 to rotate, the rolling piece 135 can roll along the contact surface of the pusher 133.

[0069] Through the setting of the rolling piece 135, the sliding friction between the transmission piece 134 and the pusher 133 can be converted into rolling friction, and the friction of the rolling friction is smaller than that of the sliding friction, which helps to reduce the wear of the pusher 133 and the transmission piece 134 and prolong the service life.

[0070] In the embodiment, as shown in Figure 2 , Figure 3 and Figure 7 , the upper die assembly 12 is provided with an avoiding groove 121, which is configured to avoid the abutting section 1321 during the movement of the telescopic piece 132 to the first position or the second position, which is helpful to reduce the risk of interference between the upper die assembly 12 and the telescopic piece 132, causing the damage of the forging press die 10, thereby further improving the service life of the forging press die 10.

[0071] For example, when forging a workpiece, the upper die assembly 12 moves in the first direction X towards the lower die assembly 11, and the pusher 133 moves to contact the rolling piece 135. At this time, the upper die assembly 12 does not contact the workpiece, and there is a gap between them.

[0072] As the upper die assembly 12 continues to move, the pusher 133 drives the transmission piece 134 to rotate, and the transmission piece 134 drives the telescopic piece 132 to move in the second direction Y to move out of the forming area 111. Wherein, during the movement of the telescopic piece 132 from the pole out of the forming area 111, the abutting section 1321 is gradually accommodated in the avoiding groove 121 to avoid the upper die assembly 12, preventing the telescopic piece 132 from interfering with the upper die assembly 12.

[0073] In the embodiment, as shown in Figures 1 to 3 , the positioning assembly 13 further comprises a first elastic piece 136, which is installed in the guide hole 1311, and one end of the first elastic piece 136 is connected with the guide seat 131, and the other end is connected with the connecting section 1322. The telescopic piece 132 is configured to move to the first position under the action of the first elastic piece 136. By setting the first elastic piece 136, the automatic reset of the telescopic piece 132 can be realized, which helps to improve the degree of automation of the forging press die 10 and improve the user's experience.

[0074] Understandably, when the upper die assembly 12 moves in the direction of approaching the lower die assembly 11 along the first direction X, the telescopic piece 132 moves to the second position. At this time, the first elastic piece 136 is in a compressed state and generates elastic potential energy. When the upper die assembly 12 moves in the direction of moving away from the lower die assembly 11 along the first direction X, the telescopic piece 132 moves to the first position under the elastic force of the first elastic piece 136.

[0075] In other embodiments, the telescopic piece 132 can also be driven by the pushing piece 133 to move to the first position, which is not limited in the application, and those skilled in the art can choose according to the actual situation.

[0076] In the embodiment, as shown in the figure, Figures 1 to 3 The positioning assembly 13 further includes a second elastic piece 137, one end of the second elastic piece 137 is connected with the transmission piece 134, and the other end is connected with the guide seat 131. The second elastic piece 137 is configured to drive the transmission piece 134 to rotate to restore to the initial position. By arranging the second elastic piece 137, the automatic reset of the transmission piece 134 can be realized, which helps to further improve the automation degree of the forging press die 10 and improve the user experience.

[0077] Understandably, when the upper die assembly 12 moves in the direction of moving away from the lower die assembly 11 along the first direction X, the upper die assembly 12 drives the pushing piece 133 to move in the direction of moving away from the transmission piece 134, and the transmission piece 134 restores to the initial position under the elastic force of the second elastic piece 137 to wait for the next work.

[0078] It is worth noting that when the transmission piece 134 starts to rotate under the drive of the pushing piece 133, the second elastic piece 137 is elastically deformed and exerts a force in the opposite direction (specifically, the opposite direction of the direction in which the pushing piece 133 drives the transmission piece 134 to rotate) on the transmission piece 134. Through the action of the second elastic piece 137, the friction between the transmission piece 134 and the pushing piece 133 can be increased, reducing the risk that the pushing piece 133 cannot drive the pushing piece 133 to rotate due to the small friction between the transmission piece 134 and the pushing piece 133.

[0079] An embodiment of the application provides a forging press equipment 100. As shown in the figure, Figure 8 The forging press equipment 100 includes a driving mechanism 20 and a forging press die 10 as described in any of the above embodiments. The forging press die 10 is connected with the driving mechanism 20, and the driving mechanism 20 is configured to drive the upper die assembly 12 and the lower die assembly 11 to move relatively along the first direction X.

[0080] The forging equipment 100 in the present application adopts the forging die 10 described above. The positioning assembly 13 in the forging die 10 is arranged outside the forming area 111, and the positioning assembly 13 positions the workpiece along the second direction Y, intersecting the movement direction (specifically, the first direction X) of the upper die assembly 12 and the lower die assembly 11. In other words, the abutting segment 1321 of the telescopic piece 132 extends into the forming area 111, and the connecting segment 1322 of the telescopic piece 132 is outside the forming area 111.

[0081] Therefore, when the user sprays the lubricating graphite into the forming area 111, the lubricating graphite can only adhere to the abutting segment 1321 of the telescopic piece 132, and it is difficult to adhere to the connecting segment 1322 of the telescopic piece 132. At the same time, in the process of moving the telescopic piece 132 along the second direction Y to the first position or the second position, the abutting segment 1321 in the telescopic piece 132 is always located outside the guide seat 131, and does not need to be in sliding fit with the guide seat 131. Thus, the risk of jamming or sticking of the positioning assembly 13 can be reduced, and the quality of workpiece pressing and the service life of the forging die 10 can be improved.

[0082] It should be further noted that, compared with the prior art positioning mechanism arranged along the forging direction in the forging die, the forging die 10 in the present application does not need to punch the lower die assembly 11, thereby improving the structural strength of the lower die assembly 11 and prolonging the service life thereof.

[0083] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any change or replacement within the technical scope disclosed in the present application should be covered within the disclosure scope of the present application.
