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: 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.
[0016] S2. The forging personnel places the connecting rod blank on the assembled lower template block. When ready, the upper template block cooperates with the impact mechanism to apply impact force to the connecting rod blank above the lower template block to complete the initial forging process.
[0017] S3. After the initial forging is completed, the positioning base releases the limit on the current assembly template, and the first synchronous displacement device drives the assembly template to carry the connecting rod blank to the cooling position. During this process, the assembly template and the connecting rod blank are separated from the fixed template. At the same time, the second synchronous displacement device is started to move another assembly template to the side of the fixed template and fix it, preparing for the next round of forging.
[0018] S4. When the assembly template and the connecting rod blank on the first synchronous displacement device reach the cooling position, water spray cooling treatment is carried out. At the same time, the assembly 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 assembly template and the connecting rod blank are driven to move to the cooling position. At this time, the first synchronous displacement device is reset.
[0019] S5. The first synchronous displacement device brings the connecting rod blank and the assembly template that have completed the cooling treatment back to the fixed template position, ready for secondary forging. This process is repeated, and the two synchronous displacement devices operate alternately, realizing forging and cooling treatment at the same time, effectively improving the overall forging efficiency, until all connecting rod blanks are forged.
[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention realizes simultaneous forging and cooling treatment through the innovative design of continuous forging device. The two synchronous displacement devices and assembly templates operate alternately to ensure that the forging operation is carried out uninterruptedly during the cooling treatment. This design effectively reduces the time of suspending forging due to cooling treatment in the traditional solution, and significantly improves the overall forging efficiency. In addition, this synchronous operation mode also optimizes the production process, reduces equipment idleness, and further reduces production costs.
[0021] 2. The spray assembly integrated in the present invention realizes uniform and rapid cooling of the connecting rod blank through the coordinated work of the upper and lower spray heads. Under the guidance of the upper and lower spray heads, the cooling water can fully contact and take away the heat from the surface of the workpiece, ensuring that the workpiece maintains an appropriate temperature during the forging process, thereby avoiding deformation or cracking caused by overheating. This efficient cooling method not only improves product quality, but also provides favorable conditions for subsequent secondary forging. At the same time, the automated operation of the spray assembly reduces manual intervention and improves the automation level of the production line.
[0022] 3. The push-up unloading device of the present invention realizes the rapid and accurate unloading of the connecting rod blank through the cooperation of the inclined guide frame and the second linear drive. After being pushed up by the inclined guide frame, the connecting rod blank can smoothly slide to the processing area, avoiding the potential safety hazards caused by manual operation. At the same time, the unloading mechanism also improves the unloading efficiency and ensures that the connecting rod blank can smoothly enter the next process. This design not only improves the smoothness of the overall production line, but also provides a strong guarantee for the safety of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0035] See also Figures 1 to 10 As shown, a forging equipment for automobile connecting rod blanks includes a continuous forging device installed below the upper template block, and is characterized in that the continuous forging device includes a positioning base 2, on which a lower template block 1 is installed, and the lower template block 1 includes a fixed template 11, and two synchronous displacement devices 13 are installed on the side of the fixed template 11, and the two synchronous displacement devices 13 are symmetrically arranged on both sides of the fixed template 11, and each synchronous displacement device 13 is installed with two assembly templates 12, and the assembly template 12 can be assembled and combined with the fixed template 11, and the synchronous displacement device 13 is used to switch and adjust the position of the assembly template 12.
[0036] During the forging process, the first synchronous displacement device 13 first moves an assembly template 12 onto 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 template block 1. Subsequently, the forger places the connecting rod blank 5 on the lower template block 1. After preparation, the upper template block cooperates with the impact mechanism to apply impact force to the connecting rod blank 5 above the lower template block 1 to complete the preliminary forging.
[0037] After the preliminary forging is completed, the connecting rod blank 5 needs to be cooled by spraying water. At this time, the positioning base 2 releases the limit on the current assembly template 12, and the first synchronous displacement device 13 immediately drives the assembly template 12 to carry the connecting rod blank 5 to the cooling position. During the movement, the assembly 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 started synchronously to move another assembly template 12 to the side of the fixed template 11, and fixed by the positioning base 2 to form a new forging preparation state. At this time, the forger can place the next connecting rod blank 5 on the newly assembled lower template block 1, and the upper template block and the impact mechanism will perform the next round of preliminary forging.
[0038] When the assembly template 12 and the connecting rod blank 5 on the first synchronous displacement device 13 reach the cooling position, they are cooled. 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 assembly template 12 and the connecting rod blank 5 to move to the cooling position. At this time, the first synchronous displacement device 13 is reset, and the connecting rod blank 5 and the assembly template 12 that have completed the cooling process are brought back to the fixed template 11 position, ready for secondary forging.
[0039] By alternately operating the two synchronous displacement devices 13, forging and cooling treatment are performed simultaneously, effectively reducing the time occupied by cooling treatment, thereby significantly improving the overall forging efficiency. This process is repeated until all connecting rod blanks 5 are forged.
[0040] The upper template block and the impact mechanism are both prior art and will not be described in detail here.
[0041] See also Figures 3 to 6 As shown, a main forging groove 111 is provided inside the fixed template 11 , and both ends of the main forging groove 111 are provided with assembly openings 112 , and the assembly openings 112 match the assembly template 12 .
[0042] As a key component of the forging equipment for the automobile connecting rod blank 5, the fixed template 11 has the main function of cooperating with the assembly template 12 to form a complete lower template block 1 so as to accurately forge the connecting rod blank 5. The interior of the fixed template 11 is designed with a main forging groove 111, the shape of which matches the expected shape of the connecting rod blank 5, ensuring that an accurate mold cavity can be provided during the forging process. Both ends of the main forging groove 111 are provided with assembly openings 112, the size and shape of which match the assembly template 12, so as to achieve seamless docking between the assembly template 12 and the fixed template 11 during the forging process.
[0043] In the forging process, when the assembly template 12 is moved to the positioning base 2 and adjacent to the fixed template 11 through the synchronous displacement device 13, the assembly template 12 is docked with the main forging groove 111 through the assembly opening 112, thereby forming a continuous and complete forging cavity. The upper template block, in cooperation with the impact mechanism, applies a precise impact force to the connecting rod blank 5 placed on the lower template block 1, so that it is formed according to the predetermined shape and size.
[0044] See also Figures 3 to 7 As shown, an installation cavity 121 is provided inside the assembly template 12, and a splicing forging groove 122 that docks with the assembly port 112 is provided on one side of the assembly template 12. A plurality of positioning docking holes 123 are also provided on the assembly template 12, and the positioning docking holes 123 are connected to the installation cavity 121. A stripping clamping mechanism 124 is provided inside the installation cavity 121.
[0045] The assembly template 12 cooperates with the fixed template 11 to form a complete lower template block 1 to meet the precise requirements of the forging process. An installation cavity 121 is provided inside the assembly template 12, and the installation cavity 121 provides space for the installation of the stripping clamping mechanism 124.
[0046] On one side of the assembly template 12, there is a splicing forging groove 122 that matches the assembly opening 112 on the fixed template 11. This ensures that the assembly template 12 can be accurately docked with 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 mold cavity for the precise forging of the connecting rod blank 5.
[0047] In addition, the assembly template 12 is provided with a plurality of positioning docking holes 123, which are connected to the installation cavity 121. During the forging process, the positioning docking holes 123 are used to cooperate with the positioning base 2 to achieve accurate fixation of the assembly template 12. When the positioning base 2 cooperates with the positioning docking holes 123, the working end of the stripping clamping mechanism 124 will remain in a retracted state to avoid interference with the placement and forging process of the connecting rod blank 5.
[0048] After forging is completed, when the assembly template 12 needs to carry the connecting rod blank 5 to the cooling position, the assembly template 12 is separated from the positioning base 2 and the fixed template 11, and the working end of the stripping clamping mechanism 124 extends out and contacts the connecting rod blank 5. This design ensures that the connecting rod blank 5 can remain stably fixed during the movement of the assembly template 12, avoiding the risk of the connecting rod blank 5 falling off due to movement.
[0049] See also Figures 5 to 9As shown, the stripping and clamping mechanism 124 includes a first linkage pushing mechanism 1242 arranged in the installation cavity 121, and the movable end of the first linkage pushing mechanism 1242 extends upward through the assembly template 12, and an outer wall resistance block 1241 is installed on the movable end of the first linkage pushing mechanism 1242, and the outer wall resistance block 1241 is used to contact the outer wall of the connecting rod blank 5.
[0050] The first linkage pushing mechanism 1242 includes two interference sliders 1243 slidably installed in the installation cavity 121, a first connecting block 1244 is installed between the two interference sliders 1243, the interference slider 1243 is slidably connected to the assembly template 12, a first connecting rod 1245 is installed between the first connecting block 1244 and the interference slider 1243, a reset 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 interference block 1241.
[0051] The first linkage pushing mechanism 1242 includes two abutting sliders 1243, which are slidably mounted in the mounting cavity 121 and connected to each other through a first connecting block 1244. A first connecting rod 1245 is installed between the first connecting block 1244 and the abutting slider 1243 to ensure synchronous movement between the two. In addition, a sliding connection is maintained between the abutting slider 1243 and the assembly template 12, and a reset 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 lost. 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 abutting block 1241.
[0052] During the forging process, when the assembly template 12 cooperates with the positioning base 2 through the positioning docking hole 123 to achieve accurate fixation of the assembly template 12, the positioning base 2 will apply a resisting force to the resisting slider 1243. After the resisting slider 1243 is pressed, the first connecting rod 1245 synchronously drives the first connecting block 1244 and the outer wall resisting block 1241 thereon to maintain a contracted state, and at this time the return spring 1246 is squeezed.
[0053] 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.
[0054] 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.
[0055] 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.
[0056] 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.
[0057] 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.
[0058] During the forging process, when the position of the assembly template 12 needs to be switched and adjusted, the synchronous driver 134 is started to drive the rotating rod 132 to rotate. The rotation of the rotating rod 132 is transmitted by the parallel rod 133, driving the assembly template 12 to move smoothly along the preset path. When the assembly template 12 moves to the target position, the synchronous driver 134 stops driving, the rotating rod 132 stops rotating, and the assembly template 12 also stops moving. At this time, the positioning base 2 accurately positions and fixes the assembly template 12 to prepare for the subsequent forging operation.
[0059] Through the alternating operation of the synchronous displacement device 13, the assembly template 12 is smoothly moved and positioned on both sides of the fixed template 11, thereby coordinating the continuous operation during the forging process, which not only improves the forging efficiency, but also ensures the stability and accuracy during the forging process.
[0060] See also Figures 3 to 5 As shown, a horizontal mounting surface 21 for mounting the lower template block 1 is provided on the top of the positioning base 2, a clearance groove 22 for cooperating with the synchronous displacement device 13 to move is provided on the positioning base 2, and clamping positioning devices 23 for fixing the assembly template 12 are installed on both sides of the positioning base 2.
[0061] The horizontal mounting surface 21 is used to accurately and firmly support the fixed template 11 and the movable assembly template 12 of the lower template block 1. The stability and accuracy of the mold during the forging process are ensured. In order to ensure that the synchronous displacement device 13 can smoothly move the assembly template 12, a clearance groove 22 is cleverly set on the positioning base 2. The clearance groove 22 provides necessary space for the parallel rod 133 and the rotating rod 132 of the moving parts of the synchronous displacement device 13, avoiding motion interference, thereby ensuring that the assembly template 12 can smoothly switch between the fixed template 11 and the cooling position. In addition, the two sides of the positioning base 2 are also equipped with a clamping positioning device 23. After the assembly template 12 moves to the predetermined position, the clamping positioning device 23 cooperates with the positioning docking hole 123 on the assembly template 12 to achieve accurate clamping and positioning fixation of the assembly template 12. It ensures the accurate docking between the assembly template 12 and the fixed template 11, providing a reliable support and positioning basis for subsequent forging operations.
[0062] In summary, the positioning base 2 achieves stable support for the lower template block 1, smooth cooperation with the synchronous displacement device 13, and precise positioning and fixation of the assembly template 12 through its horizontal mounting surface 21, the clearance groove 22 and the clamping positioning device 23.
[0063] See also Figures 4 to 9As shown, the clamping and positioning device 23 includes two second linkage pushing mechanisms 231 installed on both sides of the positioning base 2, and a positioning docking column 232 is installed on the movable end of the second linkage pushing mechanism 231, and the positioning docking column 232 is used to dock and fix the assembly template 12.
[0064] The second linkage pushing mechanism 231 includes two retractable slide bars 2311 slidably mounted on the positioning base 2, a second connecting block 2312 is provided on the side of the retractable slide bar 2311, a second connecting rod 2313 is installed between the second connecting block 2312 and the retractable slide bar 2311, and the second linkage pushing mechanism 231 also includes a first linear driver 2314 that drives the second connecting block 2312 to move.
[0065] The clamping and positioning device 23 is composed of two second linkage pushing mechanisms 231, which are respectively installed on both sides of the positioning base 2. Each second linkage pushing mechanism 231 is designed with two synchronously contracting movable ends, and the movable ends of the second linkage pushing mechanisms 231 are equipped with positioning docking columns 232, and the main function of the positioning docking columns 232 is to dock and fix the assembly template 12.
[0066] When the synchronous displacement device 13 moves the assembly template 12 to the predetermined position of the positioning base 2, the first linear driver 2314 starts to work and drives the second connection block 2312 to move. As the second connection block 2312 moves, the second connection rod 2313 triggers the synchronous contraction of the plurality of contraction slide bars 2311. The contraction of the contraction slide bars 2311 further drives the synchronous contraction of the positioning docking column 232 until the positioning docking column 232 is completely inserted into the positioning docking hole 123 on the assembly template 12.
[0067] See also Figure 3 and Fig.10 As shown, the continuous forging device also includes two groups of spray assemblies 3, which are respectively arranged on the side of each synchronous displacement device 13, each group of spray assemblies 3 includes an upper spray head 31 and a lower spray head 32, and a water cooling gap is provided between the upper spray head 31 and the lower spray head 32.
[0068] Two groups of spray assemblies 3 are respectively arranged beside each synchronous displacement device 13 to meet the requirements of alternating operation of two assembly templates 12. Each group of spray 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 the two. The water cooling gap is used to accommodate the connecting rod blank 5 to be cooled carried by the assembly template 12. The upper spray head 31 and the lower spray head 32 are both connected to the water delivery equipment to ensure a stable supply of cooling water.
[0069] During the forging process, when the synchronous displacement device 13 drives the assembly template 12 to switch and move, the assembly 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 spray assembly 3 is started, and the upper spray head 31 and the lower spray head 32 work at the same time, spraying cooling water evenly on the upper and lower sides of the connecting rod blank 5. After the cooling water contacts the high-temperature connecting rod blank 5, it quickly takes away the heat, thereby achieving rapid cooling. The spray 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 size, providing favorable conditions for subsequent secondary forging. At the same time, the automated operation of the spray assembly 3 also reduces manual intervention and improves the automation level and production efficiency of the overall forging equipment.
[0070] See also Figure 3 and Fig.10 As shown, the continuous forging device also includes two sets of ejector and feeder devices 4, which are respectively arranged beside each synchronous displacement device 13. The movable end of the ejector and feeder device 4 is provided with an inclined guide frame 41 for pushing the connecting rod blank 5 upward.
[0071] The ejecting and unloading device 4 comprises a second linear drive 42 for driving the inclined material guide frame 41 to move upward.
[0072] The movable ends of the push-pull device 4 are equipped with an inclined guide frame 41, which effectively guides 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 processing area when it is pushed. The second linear drive 42 is responsible for providing power to push the inclined guide frame 41 up.
[0073] During the forging process, when the synchronous displacement device 13 drives the assembly template 12 to switch and move, the assembly template 12 will accurately position the forged connecting rod blank 5 above the inclined guide frame 41. At this time, the second linear drive 42 is started to push the inclined guide frame 41 to rise along the preset trajectory. As the inclined guide frame 41 rises, the connecting rod blank 5 is pushed upward, so that the connecting rod blank 5 gradually separates from the assembly template 12. Since the inclined guide frame 41 has an inclined design, the connecting rod blank 5 will slide along the inclined surface after being pushed, and will eventually be guided to the area to be processed.
[0074] The ejection unloading process not only realizes the fast and accurate unloading of the connecting rod blank 5, but also effectively avoids the potential safety hazards caused by manual operation. At the same time, the design of the inclined guide frame 41 also improves the unloading efficiency, ensuring that the connecting rod blank 5 can smoothly enter the next process.
[0075] A forging method of an automobile connecting rod blank forging device comprises the following steps: S1. In the initial stage of forging, the first synchronous displacement device 13 accurately moves an assembly template 12 to the positioning base 2, and the positioning base 2 realizes accurate positioning and fixation. At this time, the assembly template 12 is combined with the fixed template 11 to form a complete lower template block 1.
[0076] S2. The forging personnel places the connecting rod blank 5 on the assembled lower template block 1. When everything is ready, the upper template block cooperates with the impact mechanism to apply impact force to the connecting rod blank 5 above the lower template block 1 to complete the initial forging process.
[0077] S3. After the preliminary forging is completed, the positioning base 2 releases the limit on the current assembly template 12, and the first synchronous displacement device 13 drives the assembly template 12 to carry the connecting rod blank 5 to the cooling position. During this process, the assembly 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 started to move another assembly template 12 to the side of the fixed template 11 and fix it, preparing for the next round of forging.
[0078] S4. When the assembly template 12 and the connecting rod blank 5 on the first synchronous displacement device 13 reach the cooling position, water spray cooling treatment is carried out. At the same time, the assembly template 12 on the second synchronous displacement device 13 has completed the preliminary forging of the current connecting rod blank 5, and then the limit is released and the assembly template 12 and the connecting rod blank 5 are driven to move to the cooling position. At this time, the first synchronous displacement device 13 is reset.
[0079] S5, the first synchronous displacement device 13 brings the connecting rod blank 5 and the assembly template 12 that have completed the cooling treatment back to the position of the fixed template 11, ready for secondary forging. This process is repeated, and the two synchronous displacement devices 13 operate alternately, realizing forging and cooling treatment at the same time, effectively improving the overall forging efficiency, until all connecting rod blanks 5 are forged.
