Description

Technical Field

[0001] This invention relates to the field of stainless steel ingot processing, and more particularly to a forming device for stainless steel ingot production. Background Technology

[0002] Stainless steel ingots are the core raw material in the wheel forging process, and their forming quality directly affects the mechanical properties and structural precision of the final product. During the forging process, in order to meet the needs of different application scenarios, stainless steel ingots need to be processed into various shapes such as round and square. Among them, round ingots often need to be forged with internal grooves because they need to match the wheel structure.

[0003] However, existing forming equipment faces significant technical bottlenecks when processing such complex structures, hindering production efficiency and safety. Firstly, mold release is a major challenge. During high-temperature forging (1000℃-1250℃), the immense extrusion force generated by the plastic deformation of stainless steel easily causes the mold to tightly fit against the inner wall of the steel ingot, leading to a dramatic increase in release resistance. Forced separation can damage the mold's surface precision, leave scratches on the inner wall of the ingot's groove, and even cause micro-cracks, severely impacting product yield. Secondly, mold operation safety is insufficient. The forged mold is heavy and has an extremely high surface temperature, posing a risk of burns during manual handling. Existing equipment lacks auxiliary mold-removal devices, significantly increasing worker workload and safety hazards. Furthermore, the equipment suffers from low automation levels. Mold reset and worktable movement rely on manual intervention, making continuous production difficult. Especially in scenarios involving frequent changes to heavy molds, equipment downtime accounts for over 30%, severely impacting production capacity.

[0004] Based on the above situation, there is an urgent need for a forming equipment for stainless steel ingot production. Summary of the Invention

[0005] In order to overcome the shortcomings of existing molding equipment, such as difficulty in mold demolding and insufficient mold operation safety, the technical problem is to provide a molding device for stainless steel ingot production.

[0006] The technical implementation of the present invention is as follows: a forming device for stainless steel ingot production includes a support frame as the main bearing body, a lifting device installed on the top of the support frame, a stamping part with a bottom opening fixedly connected to the telescopic end of the lifting device, and symmetrically distributed stamping covers slidably connected to the bottom of the stamping cover. Each stamping cover has symmetrically distributed slots on its side. The stamping part has a locking assembly for locking the stamping cover on the side near the slot. The stamping part has a second plastic part with vertically distributed insertion holes. The stamping part also has a pin assembly for locking the position of the second plastic part. A stamping table is provided on the bottom plate of the support frame.

[0007] As a further preferred embodiment, the pin assembly includes a guide rod fixed to the outside of the stamping part, on which a limiting member is slidably connected. A connecting spring is connected between the limiting member and the guide rod, and the limiting member is wound around the guide rod. The limiting member passes through the side wall of the stamping part and is inserted into the insertion hole of the second molded part.

[0008] As a further preferred embodiment, the locking assembly includes symmetrically distributed sliding limiting members connected to the stamping part, each of which is connected to the stamping part by a return spring. Each return spring is wound around the stamping part, and the limiting members slide up and down within adjacent locking slots.

[0009] As a further preferred embodiment, the limiting member is provided with an inclined surface, a fixing member is fixedly connected to the inner side of the top wall of the support frame near the limiting member, a fixing rod is fixedly connected to the inner side of the top wall of the support frame near the limiting member, a connecting column is fixedly connected to each stamping cover, and an extrusion frame is fixedly connected to the inner side of the top wall of the support frame near the connecting column.

[0010] As a further preferred embodiment, the extrusion frame is provided with symmetrically distributed inclined surfaces, the boundary line of which is located on the vertical extension line between two connecting columns, and the two are aligned in the vertical direction.

[0011] As a further preferred embodiment, the base plate of the support frame is provided with a first molded part, which is located directly below the second molded part. The stamping table and the support frame are connected by symmetrically distributed buffer springs, which are all wrapped around the stamping table. The stamping table has a through hole in the middle that matches the first molded part. The first molded part is located in the through hole of the stamping table. The stamping table is also provided with a covering component.

[0012] As a further preferred embodiment, the covering assembly includes a servo motor mounted on a support frame, the output shaft of which is connected to a bidirectional lead screw via a coupling. The bidirectional lead screw is rotatably connected to the support frame, and symmetrically distributed load-bearing platforms are threaded onto the bidirectional lead screw. These platforms are slidably connected to the support frame, and each load-bearing platform has a telescopic load-bearing plate fixed to its top.

[0013] As a further preferred embodiment, the base plate of the support frame is fixed with symmetrically distributed guide members, each of which is slidably connected to a movable member. The movable member is connected to the adjacent guide member by a fixed spring. The bottom of the stamping table is in direct contact with the movable member. The stamping member is fixed with symmetrically distributed fixed plates, which are located below the adjacent movable member.

[0014] As a further preferred embodiment, a connecting member is fixedly connected to the limiting member, which has an oblique protrusion. A movable frame is slidably connected to the support frame on the side near the connecting member, and a return spring is connected between the movable frame and the support frame. A connecting rod is fixedly connected to each limiting member. Symmetrically distributed pressing rods are fixedly connected to the support frame, which are located directly below the connecting rods. Symmetrically distributed support members are fixedly connected to the support frame on the side near the pressing rods, each of which has an inclined block.

A connecting torsion spring is connected between the one-way plate and the adjacent inclined block, and each connecting torsion spring is wound around the adjacent inclined block.

[0015] This invention automates the entire process of unlocking, moving, and relocking through the cooperation of connectors, connecting rods, and related components. After each forging, the second molded part automatically returns to its initial position and locks, while the stamping cover also closes inward and locks to its initial state, preparing for the next preliminary forging. This reduces manual intervention, ensures precise resetting of each component, and improves the stability and reliability of the equipment operation.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1: A forming device for stainless steel ingot production, such as... Figures 1-5 As shown, the device includes a support frame 1 as the main load-bearing structure, with a lifter 11 mounted on its top. The telescopic end of the lifter 11 is fixedly connected to a stamping part 12 with a bottom opening. The bottom of the lifter 11 is slidably connected to symmetrically distributed stamping covers 15. Each stamping cover 15 has symmetrically distributed slots on its side. The stamping part 12 has a locking assembly on the side near the slots to stably fix the stamping cover 15 onto the stamping part 12, and can be quickly unlocked and reset through operation. A second molded part 14 is provided inside the stamping part 12, with vertically distributed insertion holes. The stamping part 12 is also provided with a pin assembly to lock the position of the second molded part 14 inside the stamping part 12. When it is necessary to adjust the position of the second molded part 14, the locking state can be released by operating the pin assembly, so that the second molded part 14 moves downward under the action of gravity. A stamping table 13 is provided on the bottom plate of the support frame 1 for placing the stainless steel ingot to be forged.

[0028] Wheel forging is a process of manufacturing high-strength wheels through high-temperature plastic deformation. Suitable stainless steel ingots are selected and cut to appropriate sizes as needed. The stainless steel ingot is heated to a specific temperature to achieve an ideal plastic state for subsequent processing. It is then placed on a stamping table 13 and clamped by a hydraulic clamp. The lifting device 11 is then controlled to move the stamping part 12 downwards, thereby moving the stamping cover 15 downwards to perform preliminary forging of the heated stainless steel ingot, forming a basic disc shape.

[0029] When a secondary molding of a stainless steel ingot is required, the second molding part 14 is provided with symmetrically distributed protrusions, and the inner wall of the stamping part 12 is provided with a receiving plate on the side near the protrusion. The protrusion and the adjacent receiving plate are in the same vertical direction to ensure that the two are precisely aligned in the vertical direction.

[0030] When the stamping shroud 15 opens outward, the fixing of the second molded part 14 is released. At this time, the second molded part 14 falls downward under its own weight. Due to the precise fit between the protrusion and the receiving plate, when the second molded part 14 falls, its protrusion will contact the receiving plate inside the stamping part 12. Finally, the stamping part 12 steadily catches the falling second molded part 14 through the receiving plate, making it accurately stop at the target position, preparing for subsequent forging operations.

[0031] like Figure 4 As shown, the pin assembly includes a guide rod 18 fixed to the outside of the stamping part 12, on which a limiting member 17 is slidably connected. A connecting spring 19 is connected between the limiting member 17 and the guide rod 18, and the limiting member 17 is wound around the guide rod 18. The limiting member 17 passes through the side wall of the stamping part 12 and is inserted into the insertion hole of the second molded part 14. Through the cooperation between the limiting member 17 and the insertion hole, the position of the second molded part 14 can be locked.

[0032] The locking assembly includes symmetrically distributed sliding limiting members 16 connected to the stamping part 12. Each limiting member 16 is connected to the stamping part 12 with a return spring 110. Each return spring 110 is wound around the stamping part 12. The limiting members 16 slide up and down in the adjacent locking slots. Through the cooperation between the limiting members 16 and the locking slots, the stamping cover 15 can be locked on the stamping part 12.

[0033] After the stainless steel ingot is initially forged, the limiting member 17 is pulled outward to exit from the insertion hole below the second molded part 14. At this time, the connecting spring 19 is deformed, and the second molded part 14 is in a free state inside the stamping part 12. The weight of the stamping part 12 will be transmitted to the stamping cover 15, and the stamping part 12 will press on the stamping cover 15. Next, the limiting member 16 is pulled upward to exit from the bayonet of the stamping cover 15.

[0034] At this time, the return spring 110 deforms, and the stamping cover 15 is no longer restricted by the limiting member 16. The two stamping covers 15 are pulled outward so that they no longer support the second plastic part 14. The second plastic part 14 falls downward under its own weight. The receiving plate inside the stamping part 12 catches the falling second plastic part 14 and keeps it accurately in the target position, extending out of the stamping part 12. The insertion hole above it is at the same horizontal line as the limiting member 17.

[0035] Subsequently, the limiting member 17 and the restricting member 16 are released. Under the elastic force of the connecting spring 19, the limiting member 17 moves inward to the insertion hole above the second molded part 14, locking the second molded part 14 back into the stamping part 12. At the same time, under the elastic force of the return spring 110, the restricting member 16 automatically moves downward and inserts into the inner bayonet, locking the position of the stamping cover 15 and keeping it in the open state. Then, the controllable lifting device 11 drives the stamping part 12 to move downward, and the second molded part 14 also moves downward, performing secondary forging on the disc-shaped stainless steel ingot until the required groove structure is forged inside the disc.

[0036] During wheel forging, the stainless steel ingot is heated to a specific temperature, creating a high-temperature and hazardous environment in the forging zone. To ensure safety, the second molded part 14 within the stamped part 12 must be removed during the secondary forging of the stainless steel ingot. However, the current operation requires manually pulling the limiting part 17 and the restricting part 16, and pulling the two stamping covers 15 outwards to unlock and remove the second molded part 14. This manual operation is not only complex but also significantly increases the safety risks faced by workers.

[0037] Therefore, an automatic unlocking mechanism needs to be designed. By utilizing the up-and-down movement of the lifting device 11, the second molded part 14 can automatically extend from the stamping part 12 and complete the locking and unlocking actions, thereby reducing manual intervention and improving the safety and automation of the forging process.

[0038] like Figure 3 As shown, specifically, the limiting member 17 is provided with an inclined surface, and a fixing member 22 is fixedly connected to the inner side of the top wall of the support frame 1 on the side near the limiting member 17, which is used to press and cooperate with the inclined surface on the limiting member 17, thereby realizing the horizontal displacement control of the limiting member 17; a fixing rod 112 is fixedly connected to the inner side of the top wall of the support frame 1 on the side near the limiting member 16, which is used to press and cooperate with the limiting member 16, thereby controlling the sliding action of the limiting member 16 in the vertical direction.

[0039] Each stamping cover 15 is fixedly connected to a connecting post 113. The inner side of the top wall of the support frame 1 is fixedly connected to an extrusion frame 111 on the side near the connecting post 113. The extrusion frame 111 is provided with symmetrically distributed inclined surfaces. The boundary line of the inclined surfaces is located on the vertical extension line between the two connecting posts 113. The two are aligned in the vertical direction. The connecting post 113 and the inclined surface of the extrusion frame 111 are pressed together, thereby driving the stamping cover 15 to move outward and releasing the supporting effect on the second plastic part 14. Along the vertical direction, the limiting member 17, the restricting member 16, and the connecting post 113 are arranged from top to bottom. This layout ensures that the action sequence of each component at different stages is clear and coordinated with each other.

[0040] After the initial forging is completed, the control lift 11 moves the stamped part 12 upward. At this time, the limiting part 17, the restricting part 16, and the connecting column 113 move upward synchronously. The inclined surface of the limiting part 17 first contacts the fixing part 22. The fixing part 22 pushes the limiting part 17 outward through the squeezing action of the inclined surface, causing the limiting part 17 to exit from the insertion hole of the second molded part 14, releasing the lock on the second molded part 14, thus freeing the second molded part 14 within the stamped part 12. During this process, the connecting spring 19 undergoes elastic deformation to release space.

[0041] Subsequently, the limiting member 16 contacts the fixing rod 112, and the fixing rod 112 abuts against the limiting member 16, causing it to slide downward relative to the stamping member 12 and no longer jam the stamping cover 15. At the same time, the return spring 110 undergoes elastic deformation. When the stamping member 12 continues to move upward, the connecting post 113 on the stamping cover 15 contacts the extrusion frame 111. The symmetrical inclined surface of the extrusion frame 111 abuts against the connecting post 113, pushing the connecting post 113 to cause the stamping cover 15 to separate outward, so that the stamping cover 15 no longer supports the second molded part 14.

[0042] At this time, the second molded part 14, which is in a free state, falls downward due to gravity and is caught by the receiving plate inside the stamping part 12, thus realizing the state in which the second molded part 14 extends out of the stamping part 12.

[0043] Then, the control lift 11 drives the stamping part 12 to move downward, and the limiting part 17, the restricting part 16 and the connecting column 113 move downward synchronously. When the restricting part 16 separates from the fixing rod 112, under the elastic force of the return spring 110, the restricting part 16 slides upward to reset and re-engages into the slot inside the stamping cover 15, locking the stamping cover 15 in the open / closed state.

[0044] Simultaneously, when the limiting member 17 separates from the fixing member 22, under the elastic force of the connecting spring 19, the limiting member 17 slides inward to reset and re-inserts into the insertion hole above the second molded part 14, completing the re-locking of the second molded part 14. As the stamping part 12 continues to move downward, the extended second molded part 14 performs secondary forging on the disc-shaped stainless steel ingot until the required groove structure is forged inside the disc.

[0045] like Figure 2As shown, the base plate of the support frame 1 is provided with a first molding part 131, which is located directly below the second molding part 14, for preliminary molding of stainless steel ingots. The stamping table 13 and the support frame 1 are connected by symmetrically distributed buffer springs 132, which are all wrapped around the stamping table 13 to play the role of buffering and resetting. The stamping table 13 has a through hole in the middle that matches the first molding part 131. The first molding part 131 is located in the through hole of the stamping table 13 to support and form the groove structure at the bottom of the stainless steel ingot. The stamping table 13 is also provided with a cover assembly to control the state of the first molding part 131.

[0046] When the stainless steel ingot needs to be initially forged, the covering assembly completely covers and isolates the first molded part 131. At this time, the stainless steel ingot is placed on the covering assembly, and the initial forging is completed by the pressing action of the stamping cover 15. During this stage, the covering assembly ensures that the first molded part 131 does not participate in the forming process, thus avoiding affecting the effect of the initial forging.

[0047] After the initial forging is completed, the control cover assembly is moved away, exposing the first molded part 131. The disc-shaped stainless steel ingot is held by the stamping table 13, and its bottom surface contacts the first molded part 131. This operation prepares for the subsequent forming of the groove structure. When the second molded part 14 moves downward with the stamping part 12 to perform secondary forging of the stainless steel ingot, the stainless steel ingot drives the stamping table 13 to move downward during this process, and the buffer spring 132 undergoes elastic deformation.

[0048] At this point, the first molding component 131 supports the bottom of the stainless steel ingot, ensuring it is continuously stressed and in contact with the first molding component 131 during forging. As the second molding component 14 continuously applies pressure, a groove structure gradually forms on the top of the stainless steel ingot, while the bottom is marked with a groove imprint due to the action of the first molding component 131. After forging is complete, a hydraulic clamp can be used to flip the stainless steel ingot, controlling the second molding component 14 to continue forging the side with the groove imprint, further improving forging efficiency and precision.

[0049] The covering assembly includes a servo motor 3 mounted on a support frame 1. Its output shaft is connected to a bidirectional lead screw 31 via a coupling to transmit power. The bidirectional lead screw 31 is rotatably connected to the support frame 1 to ensure smooth operation. Symmetrically distributed load-bearing platforms 32 are threadedly connected to the bidirectional lead screw 31. They are slidably connected to the support frame 1 and can move horizontally under the drive of the bidirectional lead screw 31. Each load-bearing platform 32 has a telescopic load-bearing plate 33 fixed to its top to cover and shield the stamping table 13.

[0050] Initially, the support platform 32 is located below the stamping table 13, providing support. Simultaneously, the support plate 33 covers the stamping table 13, completely obscuring the first molded part 131. At this point, the stainless steel ingot to be forged is placed directly on the support plate 33. During the initial forging of the stainless steel ingot by the stamping cover 15 moving downwards with the stamping part 12, the plane formed by the two support plates 33 remains stable.

[0051] Because the support platform 32 is placed under the stamping table 13, it ensures that the stamping table 13 will not slide downwards and that the buffer spring 132 will not deform. After the initial forging is completed, the control servo motor 3 drives the bidirectional lead screw 31 to rotate, driving the support platform 32 and the support plate 33 to move outwards. The support platform 32 is removed from the bottom of the stamping table 13, and the support plate 33 no longer covers the stamping table 13, thereby exposing the first molded part 131 and entering the preparation stage for the second forging.

[0052] As mentioned earlier, during the secondary forging of the stainless steel ingot, the supporting plate 33 needs to be removed from the stamping table 13 to expose the first molded part 131. However, due to the large weight of the stainless steel ingot and its direct pressure on the supporting plate 33, the supporting table 32 is pressed down and cannot move outward smoothly. When the rotating bidirectional lead screw 31 drives the supporting table 32 to move outward, it encounters significant resistance, requiring an increase in the speed of the servo motor 3 to achieve the removal action. Therefore, a lifting mechanism needs to be designed to lift the stamping table 13 upward and remove it from the supporting table 32, thereby ensuring that the supporting table 32 and the supporting plate 33 can move outward more smoothly, completing the switching action of the covering component and meeting the requirements of secondary forging.

[0053] Specifically, the base plate of the support frame 1 is fixed with symmetrically distributed guide members 41, each of which is slidably connected to a movable member 4. Each movable member 4 is connected to an adjacent guide member 41 via a fixing spring 42. The bottom of the stamping table 13 is in direct contact with the movable member 4. When the movable member 4 moves upward, it drives the stamping table 13 to move upward as well. The stamping member 12 is fixed with symmetrically distributed fixing plates 43, each located below an adjacent movable member 4. When the stamping member 12 moves up and down with the external drive mechanism, the fixing plates 43 can hook onto the movable member 4 and move it up and down together, thereby achieving a lifting action.

[0054] When a secondary forging of a stainless steel ingot is required, as described in the preceding process: as the stamping part 12 moves upward, the fixing plate 43 on it moves upward synchronously. When the fixing plate 43 contacts the moving part 4, it hooks onto the moving part 4 and moves it up and down together, thereby driving the stamping table 13 to rise as a whole. During this process, both the fixing spring 42 and the buffer spring 132 undergo elastic deformation, and the load-bearing plate 33 extends upward to ensure that the stamping table 13 no longer presses on the load-bearing table 32. At this time, the servo motor 3 can be controlled to drive the bidirectional lead screw 31 to rotate, driving the load-bearing table 32 and the load-bearing plate 33 to move smoothly outward. After the load-bearing plate 33 is pulled out from the bottom of the stainless steel ingot, the stainless steel ingot is completely supported by the stamping table 13 and enters the secondary forging state.

[0055] When the stamping part 12 moves downward, the fixing plate 43 on it moves downward synchronously. When the fixing plate 43 separates from the moving part 4, under the action of the stainless steel ingot's own gravity, it will drive the stamping table 13 to move downward and reset, thereby driving the moving part 4 to move downward, and the fixing spring 42 and the buffer spring 132 will return to their initial length.

[0056] This embodiment utilizes the up-and-down movement of the lifting device 11 to automatically complete the extension and locking of the second molded part 14, reducing manual intervention and lowering operational risks; the added lifting mechanism makes the switching of the covering component smoother, ensuring the smooth progress of secondary forging; the equipment has a compact structure and the components work together to realize the fully automated control of the entire process from preliminary forging to secondary molding, improving forging accuracy and production efficiency.

[0057] Example 2: In the forging process of stainless steel ingots, after the second forging is completed, the second mold 14 needs to be restored to its initial state, and the stamping cover 15 needs to be closed inward to its initial position. This reset process is a key step to ensure that the system can continuously perform the next preliminary forging of stainless steel ingots until the stainless steel ingot forms a basic disc shape. Therefore, an automated mechanism must be designed so that after each forging, the second mold 14 can automatically return to its initial position and lock, while the stamping cover 15 can also close inward and lock to its initial state, thus preparing for the next forging.

[0058] like Figures 6-8 As shown, specifically, a connecting member 23 is fixedly connected to the limiting member 17, and a slanted protrusion is provided on the connecting member 23, which serves as a guide and positioning element; a movable frame 2 is slidably connected to the support frame 1 on the side near the connecting member 23, and a return spring 21 is connected between the movable frame 2 and the support frame 1. When the connecting member 23 moves downward with the limiting member 17 until it contacts the movable frame 2, the movable frame 2 will abut against the slanted protrusion of the connecting member 23, causing the connecting member 23 to drive the limiting member 17 to move outward until it exits from the insertion hole of the second molded part 14, thus completing the unlocking.

[0059] Each limiting member 16 is fixedly connected to a connecting rod 24, and the support frame 1 is fixedly connected to symmetrically distributed pressing rods 25, which are located directly below the connecting rods 24. When the connecting rods 24 move downward with the limiting member 16, they press against the pressing rods 25, causing the pressing rods 25 to abut against the connecting rods 24, thus moving the limiting member 16 upward until it exits the latch of the stamping cover 15, thereby unlocking the stamping cover 15.

[0060] The support frame 1 has symmetrically distributed support members 26 fixedly connected to one side near the extrusion rod 25. Each support member has an inclined block for guiding and stabilizing the movement of the components. A one-way plate 27 is rotatably connected to the end of each inclined block. A connecting torsion spring 28 is connected between the one-way plate 27 and the adjacent inclined block. Each connecting torsion spring 28 is wound around the adjacent inclined block, serving to reset and lock. When the connecting column 113 moves upward to contact the extrusion frame 111, the connecting column 113 is directly above the one-way plate 27, ensuring the linkage and stability between the components.

[0061] After the stainless steel ingot is forged and clamped off the stamping table 13 by the hydraulic clamp, the control lift 11 moves the stamped part 12 downward. At this time, the connecting part 23, connecting rod 24, and connecting column 113 move downward synchronously. When the connecting part 23 contacts the moving frame 2, its oblique protrusion is abutted by the moving frame 2. As the stamped part 12 continues to move downward, the connecting part 23 moves the limiting part 17 outward, causing it to exit the insertion hole of the second molded part 14, thereby unlocking the second molded part 14, and the connecting spring 19 will deform.

[0062] As the stamped part 12 continues to move downward, the second molded part 14 inside first contacts the first molded part 131 and is lifted up. Subsequently, the stamped part 12 contacts the stamping table 13, and the second molded part 14 moves upward relative to the stamped part 12; at this time, after the downward-moving connecting part 23 passes the moving frame 2, under the elastic force of the connecting spring 19, the limiting part 17 moves inward and finally abuts against the side wall of the second molded part 14.

[0063] During the downward movement of the stamped part 12, the connecting rod 24 contacts and is compressed by the pressing rod 25, pushing the limiting member 16 to slide upward relative to the stamped part 12, causing it to exit from the bayonet of the stamping cover 15, thereby releasing the lock on the stamping cover 15. At the same time, the return spring 110 deforms. When the downward-moving connecting post 113 contacts the one-way plate 27, it is pressed down and flipped, and the connecting torsion spring 28 is twisted. After the connecting post 113 passes the one-way plate 27, the one-way plate 27 flips upward and resets under the action of the connecting torsion spring 28.

[0064] Subsequently, the control lift 11 moves the stamping part 12 upward to reset, and the connecting column 113 moves upward synchronously. The connecting column 113 is abutted by the inclined block, causing the stamping cover 15 to move inward and close. The closed stamping cover 15 squeezes the second molded part 14, raising it upward until its lower side slot aligns with the limiting member 17. Then the limiting member 17 inserts into the insertion hole below the second molded part 14, completing the locking of its position.

[0065] When the upward-moving connecting rod 24 separates from the pressing rod 25, the return spring 110 restores its deformation, pushing the limiting member 16 to move the connecting rod 24 downward to reset, and it re-engages into the slot on the outside of the stamping cover 15, completing the locking of the stamping cover 15 in the closed state. When the upward-moving connecting member 23 contacts the moving frame 2, its oblique protrusion is abutted by the moving frame 2. As the connecting member 23 continues to move upward, the moving frame 2 moves to the right, and the return spring 21 deforms. After the connecting member 23 passes the moving frame 2, under the elastic force of the return spring 21, the moving frame 2 moves to the left to reset.

[0066] This embodiment achieves full automation of unlocking, moving, and relocking through the cooperation of connector 23, connecting rod 24, and related components. After each forging, the second molded part 14 can automatically return to its initial position and lock, while the stamping cover 15 also closes inward and locks to its initial state, preparing for the next preliminary forging. This reduces manual intervention, ensures accurate resetting of each component, and improves the stability and reliability of equipment operation.

[0067] Although this disclosure has been shown and described with reference to specific exemplary embodiments thereof, those skilled in the art will understand that various changes in form and detail may be made to this disclosure without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents. Therefore, the scope of this disclosure should not be limited to the above embodiments, but should be defined not only by the appended claims, but also by their equivalents.
