Description

Technical Field

[0001] The present invention relates to the technical field of forging of automobile parts, and specifically relates to a forging device and a forging method for a blank of an automobile connecting rod. Background Art

[0002] Automobile connecting rod blanks are generally processed and produced by forging equipment. Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation to obtain workpieces with certain mechanical properties, certain shapes, and dimensions.

[0003] Chinese Patent Publication No. CN118905134A discloses a forging device and a forging method for a blank of an automobile part connecting rod, including a frame, an impact mechanism, and an upper die plate, and further including a matching assembly; the matching assembly includes a support base, a lower die plate, an embedding box, an ejection bracket, a lifting member, a flushing member, a connecting member, and a blanking member; the support base is fixedly connected to the frame, the lower die plate is connected to the support base, the embedding box is connected to the support base through the connecting member, the ejection bracket is connected to the embedding box and is located on one side of the embedding box, the lifting member is connected to the ejection bracket, the flushing member is connected to the frame, the connecting member is connected to the lower die plate, and the blanking member is located on one side of the frame, realizing that the workpiece can be lifted and spray-cooled during the processing through the provided members, without manual operation, making the entire operation process more convenient and safe.

[0004] The above technical solution integrates a spray cooling system in the forging equipment. The spray cooling system can automatically lift the workpiece when forging pauses and uniformly cool the workpiece through the spray component. However, this solution has a significant problem: each time spray cooling is performed, the forging process must be completely stopped until the workpiece is spray-cooled and re-placed on the lower die plate before it can continue. Such frequent start-stop not only greatly reduces the forging efficiency but also increases the production cost. Summary of the Invention

[0005] In view of the above problems, a forging device and a forging method for a blank of an automobile connecting rod are provided, which can effectively reduce the production cost and improve the forging efficiency through a continuous forging device.

[0006] To solve the problems of the prior art, the present invention provides a forging device for a blank of an automobile connecting rod, including a continuous forging device installed below the upper die plate. The continuous forging device includes a positioning base, on which a lower die plate is installed. The lower die plate includes a fixed template, and two synchronous displacement devices are installed beside the fixed template. The two synchronous displacement devices are symmetrically arranged on both sides of the fixed template. Two assembling templates are installed on each synchronous displacement device, and the assembling templates can be assembled and combined with the fixed template. The synchronous displacement device is used to switch and adjust the position of the assembling template.

[0007] Preferably, a main forging groove is provided inside the fixed template, and both ends of the main forging groove are provided with assembly openings, and the assembly openings match the assembly template.

[0008] Preferably, an installation cavity is provided inside the assembly template, a splicing forging groove docking with the assembly port is provided on one side of the assembly template, a plurality of positioning docking holes are also provided on the assembly template, the positioning docking holes are connected to the installation cavity, and a stripping clamping mechanism is provided inside the installation cavity.

[0009] Preferably, the stripping and clamping mechanism includes a first linkage pushing mechanism arranged in the installation cavity, the movable end of the first linkage pushing mechanism extends upward through the assembly template, and an outer wall resistance block is installed on the movable end of the first linkage pushing mechanism, and the outer wall resistance block is used to contact the outer wall of the connecting rod blank.

[0010] Preferably, the synchronous displacement device includes a mounting base, on which a plurality of rotating rods are provided, and a parallel rod is installed on the side of each rotating rod. The ends of the parallel rods and the rotating rods away from the mounting base are connected to the assembly template, and the rotation of the parallel rods and the rotating rods is used to drive the assembly template to move smoothly.

[0011] Preferably, a horizontal mounting surface for mounting the lower template block is provided on the top of the positioning base, a clearance groove for cooperating with the movement of the synchronous displacement device is provided on the positioning base, and clamping positioning devices for fixing the assembled template are installed on both sides of the positioning base.

[0012] Preferably, the clamping and positioning device includes two second linkage pushing mechanisms installed on both sides of the positioning base, and positioning docking columns are installed on the movable ends of the second linkage pushing mechanisms. The positioning docking columns are used to dock and fix the assembly template.

[0013] Preferably, the continuous forging device further comprises two groups of spray assemblies, which are respectively arranged beside each synchronous displacement device, each group of spray assemblies comprises an upper spray head and a lower spray head, and a water cooling gap is provided between the upper spray head and the lower spray head.

[0014] Preferably, the continuous forging device further comprises two sets of ejector and unloading devices, which are respectively arranged beside each synchronous displacement device, and the movable ends of the ejector and unloading devices are provided with inclined guide frames for pushing the connecting rod blank upward.

[0015] A forging method of an automobile connecting rod blank forging device comprises the following steps:

[0016] S1. In the initial stage of forging, the first synchronous displacement device accurately moves an assembly template to the positioning base, and the positioning base realizes accurate positioning and fixation. At this time, the assembly template and the fixed template are combined to form a complete lower template block.

[0017] S2. The forging worker places the connecting rod blank on the assembled lower die plate. After getting ready, the upper die plate cooperates with the impact mechanism to apply an impact force to the connecting rod blank above the lower die plate to complete the preliminary forging process.

[0018] S3. After the preliminary forging is completed, the positioning base releases the limit on the current assembled template. The first synchronous displacement device drives the assembled template to carry the connecting rod blank to the cooling position. During this process, the assembled template and the connecting rod blank are disengaged from the fixed template. At the same time, the second synchronous displacement device is activated to move another assembled template to the side of the fixed template and fix it, preparing for the next round of forging.

[0019] S4. When the assembled template and the connecting rod blank on the first synchronous displacement device reach the cooling position, water spraying and cooling treatment are carried out. At the same time, the assembled template on the second synchronous displacement device has completed the preliminary forging of the current connecting rod blank, and then the limit is released and the assembled template and the connecting rod blank are driven to move towards the cooling position. At this time, the first synchronous displacement device resets.

[0020] S5. The first synchronous displacement device brings the connecting rod blank and the assembled template that have completed the cooling treatment back to the position of the fixed template to prepare for secondary forging. This process repeats. The two synchronous displacement devices operate alternately, realizing simultaneous forging and cooling treatment, effectively improving the overall forging efficiency until all connecting rod blanks are forged.

[0021] The beneficial effects of the present invention compared with the prior art are as follows:

[0022] 1. Through the innovative design of the continuous forging device, the present invention realizes simultaneous forging and cooling treatment. The two synchronous displacement devices and the assembled template operate alternately, ensuring that the forging operation continues without interruption during the cooling treatment. This design effectively reduces the time for forging to pause due to cooling treatment in the traditional solution, significantly improving the overall forging efficiency. In addition, this synchronous operation mode also optimizes the production process, reduces equipment idleness, and further reduces production costs.

[0023] 2. The integrated spraying component in the present invention realizes uniform and rapid cooling of the connecting rod blank through the coordinated work of the upper spray head and the lower spray head. Under the guidance of the upper and lower spray heads, the cooling water can fully contact and take away the heat on the surface of the workpiece, ensuring that the workpiece maintains an appropriate temperature during the forging process, thus avoiding deformation or cracking caused by overheating. This efficient cooling method not only improves the product quality but also provides favorable conditions for subsequent secondary forging. At the same time, the automated operation of the spraying component reduces manual intervention and improves the automation level of the production line.

[0024] 3. The pushing and discharging device of the present invention realizes the rapid and accurate discharging of the connecting rod blank parts through the cooperation of the inclined material guiding frame and the second linear driver. After being pushed by the inclined material guiding frame, the connecting rod blank parts can smoothly slide to the area to be processed, avoiding potential safety hazards that may be brought by manual operation. At the same time, this discharging mechanism also improves the discharging efficiency and ensures that the connecting rod blank parts can smoothly enter the next process. This design not only improves the smoothness of the overall production line but also provides strong protection for the safety of the operators. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] See Figures 1 to 10 As shown, a forging device for an automotive connecting rod blank part includes a continuous forging device installed below the upper die plate. It is characterized in that the continuous forging device includes a positioning base 2, on which a lower die plate 1 is installed. The lower die plate 1 includes a fixed template 11, and two synchronous displacement devices 13 are installed on the side of the fixed template 11. The two synchronous displacement devices 13 are symmetrically arranged on both sides of the fixed template 11. Two assembly templates 12 are installed on each synchronous displacement device 13. The assembly templates 12 can be assembled and combined with the fixed template 11, and the synchronous displacement device 13 is used to switch and adjust the positions of the assembly templates 12.

[0039] During the forging process, first, a synchronous displacement device 13 moves an assembly template 12 to the positioning base 2, and the positioning base 2 realizes precise positioning and fixation. At this time, the assembly template 12 and the fixed template 11 are combined to form a complete lower die plate 1. Subsequently, the forging operator places the connecting rod blank part 5 on the lower die plate 1. After preparation, the upper die plate cooperates with the impact mechanism to apply an impact force to the connecting rod blank part 5 above the lower die plate 1 to complete the preliminary forging.

[0040] After the initial forging is completed, the connecting rod blank 5 needs to be subjected to a water spraying and cooling treatment. At this time, the positioning base 2 releases the limit on the current assembling template 12, and the first synchronous displacement device 13 immediately drives the assembling template 12 to carry the connecting rod blank 5 to the cooling position. During the movement, the assembling template 12 is disengaged from the fixed template 11 together with the connecting rod blank 5. At the same time, the second synchronous displacement device 13 is started synchronously, moving another assembling template 12 to the side of the fixed template 11 and fixing it by the positioning base 2 to form a new forging preparation state. At this time, the forging operator can place the next connecting rod blank 5 on the newly assembled lower die block 1, and the upper die block and the impact mechanism perform the next round of initial forging.

[0041] When the assembling template 12 and the connecting rod blank 5 on the first synchronous displacement device 13 reach the cooling position, the cooling treatment is carried out. At the same time, after the second synchronous displacement device 13 completes the initial forging of the current connecting rod blank 5, it also releases the limit and drives the assembling template 12 and the connecting rod blank 5 to move towards the cooling position. At this time, the first synchronous displacement device 13 resets, bringing the connecting rod blank 5 and the assembling template 12 that have completed the cooling treatment back to the position of the fixed template 11, ready for secondary forging.

[0042] Through the alternating operation of the two synchronous displacement devices 13, forging and cooling treatment are carried out simultaneously, effectively reducing the time occupied by the cooling treatment, thereby significantly improving the overall forging efficiency. This process repeats until all the connecting rod blanks 5 are forged.

[0043] The upper die block and the impact mechanism are both prior arts and will not be elaborated here.

[0044] See Figures 3 to 6 As shown, the main forging groove 111 is provided inside the fixed template 11, and assembling ports 112 are provided at both ends of the main forging groove 111, and the assembling ports 112 are matched with the assembling template 12.

[0045] The fixed template 11, as a key component of the forging equipment for the automotive connecting rod blank 5, its main function is to cooperate with the assembling template 12 to jointly form the complete lower die block 1 for precisely forging the connecting rod blank 5. The main forging groove 111 is designed inside the fixed template 11, and the shape of the main forging groove 111 matches the expected shape of the connecting rod blank 5 to ensure that an accurate die cavity can be provided during the forging process. Assembling ports 112 are provided at both ends of the main forging groove 111, and the size and shape of the assembling ports 112 are adapted to the assembling template 12 to achieve seamless docking between the assembling template 12 and the fixed template 11 during the forging process.

[0046] In the forging process, when the assembled template 12 is moved to the positioning base 2 through the synchronous displacement device 13 and is adjacent to the fixed template 11, the assembled template 12 is docked with the main forging groove 111 through the assembly opening 112, thereby forming a continuous and complete forging cavity. Under the action of the upper die plate cooperating with the impact mechanism, an accurate impact force is applied to the connecting rod blank 5 placed on the lower die plate 1, so that it is formed according to the predetermined shape and size.

[0047] See Figures 3 to 7 As shown, an installation cavity 121 is provided inside the assembled template 12. A splicing forging groove 122 docked with the assembly opening 112 is provided on one side of the assembled template 12. A plurality of positioning docking holes 123 are also provided on the assembled template 12. The positioning docking holes 123 communicate with the installation cavity 121, and a stripping and clamping mechanism 124 is provided inside the installation cavity 121.

[0048] The assembled template 12 cooperates with the fixed template 11 to jointly form the complete lower die plate 1 to meet the precise requirements in the forging process. An installation cavity 121 is provided inside the assembled template 12, and the installation cavity 121 provides space for the installation of the stripping and clamping mechanism 124.

[0049] On one side of the assembled template 12, there is a splicing forging groove 122 matching the assembly opening 112 on the fixed template 11. It ensures that the assembled template 12 can be accurately docked to the main forging groove 111 of the fixed template 11, thereby forming a continuous and complete forging cavity. The shape of the cavity matches the expected shape of the connecting rod blank 5, providing the necessary die cavity for the precise forging of the connecting rod blank 5.

[0050] In addition, a plurality of positioning docking holes 123 are provided on the assembled template 12, and the positioning docking holes 123 communicate with the installation cavity 121. During the forging process, the positioning docking holes 123 are used to cooperate with the positioning base 2 to achieve precise fixation of the assembled template 12. When the positioning base 2 cooperates with the positioning docking holes 123, the working end of the stripping and clamping mechanism 124 will remain in a contracted state to avoid interfering with the placement and forging process of the connecting rod blank 5.

[0051] After forging is completed, when the assembled template 12 needs to move the connecting rod blank 5 to the cooling position, at this time, the assembled template 12 is separated from the positioning base 2 and the fixed template 11, and the working end of the stripping and clamping mechanism 124 extends out and abuts against the connecting rod blank 5. This design ensures that the connecting rod blank 5 can be stably fixed during the movement of the assembled template 12, avoiding the risk of the connecting rod blank 5 falling off due to movement.

[0052] See Figures 5 to 9As shown, the stripping and clamping mechanism 124 includes a first linkage pushing mechanism 1242 disposed in the installation cavity 121. The movable end of the first linkage pushing mechanism 1242 extends upward through the assembly template 12, and an outer wall contact block 1241 is installed on the movable end of the first linkage pushing mechanism 1242. The outer wall contact block 1241 is used to contact the outer wall of the connecting rod blank 5.

[0053] The first linkage pushing mechanism 1242 includes two contact sliders 1243 slidably installed in the installation cavity 121. A first connecting block 1244 is installed between the two contact sliders 1243. The contact sliders 1243 are slidably connected to the assembly template 12. First connecting rods 1245 are installed between the first connecting block 1244 and the contact sliders 1243. A return spring 1246 is also installed between the first connecting block 1244 and the assembly template 12. The top of the first connecting block 1244 extends upward through the assembly template 12, and the top of the first connecting block 1244 is fixedly connected to the bottom of the outer wall contact block 1241.

[0054] The first linkage pushing mechanism 1242 includes two contact sliders 1243 which are slidably installed in the installation cavity 121 and are connected to each other through a first connecting block 1244. First connecting rods 1245 are installed between the first connecting block 1244 and the contact sliders 1243 to ensure synchronous movement between them. In addition, the contact sliders 1243 are slidably connected to the assembly template 12, and a return spring 1246 is installed between the first connecting block 1244 and the assembly template 12 to reset the first connecting block 1244 when the external force is removed. The top of the first connecting block 1244 passes through the assembly template 12 and extends upward, and the extension of the first connecting block 1244 is fixedly connected to the bottom of the outer wall contact block 1241.

[0055] During forging, when the assembly template 12 is precisely fixed by cooperating with the positioning base 2 through the positioning docking holes 123, the positioning base 2 applies a pressing force to the contact sliders 1243. After being pressed, the contact sliders 1243 synchronously drive the first connecting block 1244 and the outer wall contact block 1241 thereon to remain in a contracted state through the first connecting rods 1245, and at this time the return spring 1246 is compressed.

[0056] When forging is completed, the assembly template 12 needs to carry the connecting rod blank 5 to the cooling position, and when the positioning base 2 releases the cooperation with the positioning docking hole 123, the resistance slider 1243 loses the resistance pressure from the positioning base 2. At this time, the reset spring 1246 releases its stored energy and pushes the first connecting block 1244 to reset and move. The reset movement of the first connecting block 1244 further drives the outer wall resistance block 1241 to extend until it contacts the outer wall of the connecting rod blank 5, thereby achieving stable fixation of the connecting rod blank 5 during the movement of the assembly template 12, avoiding the risk of falling off due to movement.

[0057] See also Figures 3 to 5 As shown, the synchronous displacement device 13 includes a mounting base 131, on which a plurality of rotating rods 132 are provided, and a parallel rod 133 is installed on the side of each rotating rod 132, and the parallel rods 133 and the rotating rods 132 are connected to the assembly template 12 at one end away from the mounting base 131, and the parallel rods 133 and the rotating rods 132 rotate to drive the assembly template 12 to move smoothly.

[0058] The synchronous displacement device 13 further includes a synchronous driver 134 for driving the rotating rod 132 to rotate. The synchronous driver 134 is a prior art and will not be described in detail herein.

[0059] The mounting base 131 provides a stable support foundation for the entire synchronous displacement device 13. A plurality of rotating rods 132 are provided on the mounting base 131, and the rotating rods 132 are rotatably connected to the mounting base 131. A parallel rod 133 is installed on the side of each rotating rod 132, and the parallel rod 133 is parallel to the rotating rod 132. The parallel rod 133 is also rotatably connected to the mounting base 131, and the ends of both of them away from the mounting base 131 are rotatably connected to the assembly template 12. The coordinated movement of the rotating rod 132 and the parallel rod 133 is ensured, so that the assembly template 12 can be driven to move smoothly.

[0060] The synchronous driver 134 is used as a driving source to synchronously drive the rotating rods 132 on the two synchronous displacement devices 13 to rotate synchronously. Under the drive of the synchronous driver 134, the rotating rod 132 starts to rotate, and cooperates with the transmission effect of the parallel rod 133 to drive the assembly template 12 to move. Since the rotating rods 132 on the two synchronous displacement devices 13 are synchronously driven by the synchronous driver 134, the synchronization of multiple assembly templates 12 during the movement process can be ensured to avoid displacement deviation.

[0061] During the forging process, when it is necessary to switch and adjust the position of the assembled template 12, the synchronous drive 134 is activated to drive the rotating rod 132 to rotate. The rotation of the rotating rod 132 is transmitted through the cooperation of the parallel rod 133, driving the assembled template 12 to move smoothly along a preset path. When the assembled template 12 moves to the target position, the synchronous drive 134 stops driving, the rotating rod 132 stops rotating, and the assembled template 12 also stops moving. At this time, the positioning base 2 accurately positions and fixes the assembled template 12, preparing for the subsequent forging operation.

[0062] Through the alternating operation of the synchronous displacement device 13, the smooth movement and positioning of the assembled template 12 on both sides of the fixed template 11 are achieved, thus coordinating with the continuous operation during the forging process. This not only improves the forging efficiency but also ensures the stability and accuracy during the forging process.

[0063] See Figures 3 to 5 As shown, the top of the positioning base 2 is provided with a horizontal mounting surface 21 for mounting the lower die plate 1, the positioning base 2 is provided with a relief groove 22 for cooperating with the movement of the synchronous displacement device 13, and clamping and positioning devices 23 for fixing the assembled template 12 are installed on both sides of the positioning base 2.

[0064] The horizontal mounting surface 21 is used to accurately and stably support the fixed template 11 of the lower die plate 1 and the movable assembled template 12. This ensures the stability and accuracy of the die during the forging process. To ensure that the synchronous displacement device 13 can smoothly move the assembled template 12, the relief groove 22 is cleverly provided on the positioning base 2. The relief groove 22 provides the necessary space for the parallel rod 133 and the rotating rod 132, which are the moving parts of the synchronous displacement device 13, avoiding movement interference and thus ensuring that the assembled template 12 can smoothly switch between the fixed template 11 and the cooling position. In addition, clamping and positioning devices 23 are equipped on both sides of the positioning base 2. After the assembled template 12 moves to the predetermined position, the clamping and positioning device 23, through cooperation with the positioning docking holes 123 on the assembled template 12, realizes the precise clamping and positioning fixation of the assembled template 12. This ensures the precise docking between the assembled template 12 and the fixed template 11, providing a reliable support and positioning basis for the subsequent forging operation.

[0065] In summary, through its horizontal mounting surface 21, relief groove 22, and clamping and positioning device 23, the positioning base 2 realizes the stable support of the lower die plate 1, the smooth cooperation with the synchronous displacement device 13, and the precise positioning and fixation of the assembled template 12.

[0066] See Figures 4 to 9As shown, the clamping and positioning device 23 includes two second linkage pushing mechanisms 231 mounted on both sides of the positioning base 2. A positioning docking post 232 is mounted on the movable end of the second linkage pushing mechanism 231. The positioning docking post 232 is used to dock and fix the assembled formwork 12.

[0067] The second linkage pushing mechanism 231 includes two retractable sliding rods 2311 slidably mounted on the positioning base 2. A second connecting block 2312 is provided beside the retractable sliding rod 2311. A second connecting rod 2313 is mounted between the second connecting block 2312 and the retractable sliding rod 2311. The second linkage pushing mechanism 231 further includes a first linear driver 2314 for driving the second connecting block 2312 to move.

[0068] The clamping and positioning device 23 is composed of two second linkage pushing mechanisms 231, which are respectively mounted on both sides of the positioning base 2. Each second linkage pushing mechanism 231 is designed with two synchronously retractable movable ends. A positioning docking post 232 is equipped on the movable end of the second linkage pushing mechanism 231. The main function of the positioning docking post 232 is to dock and fix the assembled formwork 12.

[0069] When the synchronous displacement device 13 moves the assembled formwork 12 to the predetermined position of the positioning base 2, the first linear driver 2314 starts to work and drives the second connecting block 2312 to move. With the movement of the second connecting block 2312, the synchronous contraction of a plurality of retractable sliding rods 2311 is caused through the second connecting rod 2313. The contraction action of the retractable sliding rod 2311 further drives the synchronous contraction of the positioning docking post 232 until the positioning docking post 232 is completely inserted into the positioning docking hole 123 on the assembled formwork 12.

[0070] See Figure 3 and Figure 10 As shown, the continuous forging device further includes two groups of spraying assemblies 3, which are respectively arranged beside each synchronous displacement device 13. Each group of spraying assemblies 3 includes an upper spray head 31 and a lower spray head 32, and there is a water cooling gap between the upper spray head 31 and the lower spray head 32.

[0071] Two groups of spraying assemblies 3 are respectively arranged beside each synchronous displacement device 13 to meet the requirements of the alternating operation of the two assembled formworks 12. Each group of spraying assemblies 3 is composed of an upper spray head 31 and a lower spray head 32, and a certain water cooling gap is formed between them. The water cooling gap is used to accommodate the connecting rod blank 5 carried by the assembled formwork 12. Both the upper spray head 31 and the lower spray head 32 are connected to the water supply equipment to ensure the stable supply of cooling water.

[0072] During the forging process, when the synchronous displacement device 13 drives the assembled template 12 to switch and move, the assembled template 12 will accurately displace the connecting rod blank 5 that has completed the preliminary forging into the water cooling gap. At this time, the spraying assembly 3 is activated, and the upper spray head 31 and the lower spray head 32 work simultaneously to evenly spray cooling water on the upper and lower sides of the connecting rod blank 5. After the cooling water comes into contact with the high-temperature connecting rod blank 5, it quickly takes away the heat, thereby achieving rapid cooling. The spraying assembly 3 not only improves the cooling efficiency of the connecting rod blank 5 but also helps to maintain the stability of its shape and dimensions, providing favorable conditions for the subsequent secondary forging. At the same time, the automated operation of the spraying assembly 3 also reduces manual intervention, improving the automation level and production efficiency of the overall forging equipment.

[0073] See Figure 3 and Figure 10 As shown, the continuous forging device further includes two sets of pushing and discharging devices 4, which are respectively arranged beside each synchronous displacement device 13. The movable end of the pushing and discharging device 4 is provided with an inclined guide frame 41 for pushing up the connecting rod blank 5.

[0074] The pushing and discharging device 4 includes a second linear driver 42 for driving the inclined guide frame 41 to move upward.

[0075] The movable ends of the pushing and discharging devices 4 are all equipped with inclined guide frames 41, which effectively guide the movement of the connecting rod blank 5. The inclination angle of the inclined guide frame 41 is used to ensure that the connecting rod blank 5 can slide smoothly to the area to be processed when receiving the driving force. The second linear driver 42 is responsible for providing the power to push the inclined guide frame 41 upward.

[0076] During the forging process, when the synchronous displacement device 13 drives the assembled template 12 to switch and move, the assembled template 12 will accurately position the forged connecting rod blank 5 above the inclined guide frame 41. At this time, the second linear driver 42 is activated to push the inclined guide frame 41 to rise along the preset trajectory. As the inclined guide frame 41 rises, it pushes up the connecting rod blank 5, causing the connecting rod blank 5 to gradually separate from the assembled template 12. Due to the inclined design of the inclined guide frame 41, the connecting rod blank 5 will slide along the inclined surface after receiving the driving force and will ultimately be guided to the area to be processed.

[0077] The pushing and discharging process not only realizes the rapid and accurate discharging of the connecting rod blank 5 but also effectively avoids potential safety hazards that may be brought by manual operation. At the same time, the design of the inclined guide frame 41 also improves the discharging efficiency, ensuring that the connecting rod blank 5 can smoothly enter the next process.

[0078] A forging method for a forging equipment of an automotive connecting rod blank includes the following steps:

[0079] S1. In the initial stage of forging, the first synchronous displacement device 13 accurately moves an assembled template 12 to the positioning base 2, and the positioning base 2 achieves precise positioning and fixation. At this time, the assembled template 12 and the fixed template 11 are combined to form a complete lower die block 1.

[0080] S2. The forging operator places the connecting rod blank 5 on the assembled lower die block 1. After preparation, the upper die block cooperates with the impact mechanism to apply an impact force to the connecting rod blank 5 above the lower die block 1 to complete the preliminary forging process.

[0081] S3. After the preliminary forging is completed, the positioning base 2 releases the limit on the current assembled template 12. The first synchronous displacement device 13 drives the assembled template 12 to carry the connecting rod blank 5 to the cooling position. During this process, the assembled template 12 and the connecting rod blank 5 are separated from the fixed template 11. At the same time, the second synchronous displacement device 13 is activated to move another assembled template 12 to the side of the fixed template 11 and fix it, preparing for the next round of forging.

[0082] S4. When the assembled template 12 and the connecting rod blank 5 on the first synchronous displacement device 13 reach the cooling position, water spraying cooling treatment is carried out. At the same time, the assembled template 12 on the second synchronous displacement device 13 has completed the preliminary forging of the current connecting rod blank 5. Then the limit is released and the assembled template 12 and the connecting rod blank 5 are driven to move towards the cooling position. At this time, the first synchronous displacement device 13 is reset.

[0083] S5. The first synchronous displacement device 13 brings the connecting rod blank 5 and the assembled template 12 that have completed the cooling treatment back to the position of the fixed template 11 to prepare for secondary forging. This process is repeated in a cycle, and the two synchronous displacement devices 13 operate alternately, realizing simultaneous forging and cooling treatment, effectively improving the overall forging efficiency until all the connecting rod blanks 5 are forged.

[0084] The above embodiments only represent one or several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be understood as a limitation on the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
