Description

Technical Field

[0001] The present invention belongs to the technical field of mold equipment, and in particular relates to an intelligent replacement device for stamping molds used in steel structure processing. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. The characteristics of steel are high strength, light weight, good overall rigidity and strong deformation ability. Therefore, it is particularly suitable for the construction of large-span, super-high and super-heavy buildings. These steel structures are usually made of metal plates and processed by mechanized stamping and bending.

[0003] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to make them plastically deform or separate, thereby obtaining a workpiece (stamping part) of the desired shape and size. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. Among them, the stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping, called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to make it separate or plastically deform, thereby obtaining the desired parts.

[0004] However, after long-term use, the existing stamping dies will generate a lot of heat due to impact and cannot be quickly dissipated, which can easily cause the dies to be damaged by heat, making the stamped products defective. Therefore, the die punch head needs to be replaced regularly, and the stamping operation will be suspended when the die is replaced, which will affect production efficiency. In addition, it is impossible to quickly replace dies of different models, resulting in a large production window period when changing products for production, resulting in reduced production efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent replacement device for stamping dies for steel structure processing, which can effectively drive the rapid replacement of dies through the adjustment structure, and can use the dies quickly through the fixing mechanism, effectively reducing the replacement time of the dies.

[0040] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0041] like Figure 1-Figure 10 As shown, a stamping die intelligent replacement device for steel structure processing includes a workbench 10, a mounting groove 11 and a driving hole 12 are provided on the workbench 10, and a support rod 13 is fixed above the workbench 10;

[0042] The adjusting mechanism 20 includes an adjusting ring 21 rotatably arranged in the mounting groove 11, and a transmission assembly 22 rotatably arranged in the driving hole 12. A positioning cylinder 211 and a positioning block 212 are arranged above the adjusting ring 21. The output end of the transmission assembly 22 is slidably connected with the positioning cylinder 211 through a driving plate 23, and the transmission assembly 22 is arranged at the output end of the driving assembly 24.

[0043] The mold assembly 30 is disposed above the positioning block 212, and the mold assembly 30 includes a stamping lower mold 31 and a stamping upper mold 32;

[0044] The fixing mechanism 40 includes a fixing plate 41 disposed on the support rod 13, and a driving hydraulic cylinder 42 and a fixing push rod 43 are disposed on the fixing plate 41. The output end of the driving hydraulic cylinder 42 is slidably connected to the mold assembly 30 through a connecting plate 421, and the output end of the fixing push rod 43 is slidably connected to the positioning cylinder 211 through a fixer 431;

[0045] Among them, the driving assembly 24 drives the transmission assembly 22 to rotate, driving the driving plate 23 and the positioning cylinder 211 to act, and then driving the adjustment ring 21 to rotate in the installation groove 11, and the mold assembly 30 is driven by the adjustment ring 21 to be quickly replaced, and the adjustment ring 21 and the mold assembly 30 are positioned by the fixing mechanism 40 to ensure the stability of the mold during use, and drive the upper mold and the lower mold to separate, ensuring effective stamping work.

[0046] It should be noted that the device is equipped with a control device, which has a control module. By setting the control module, the number of stamping times of the mold can be effectively controlled. When the mold reaches the number of times used, the adjustment mechanism 20 will be automatically controlled to drive the mold assembly 30 to be replaced, which can effectively improve the service life of the mold. Among them, when the transmission assembly 22 is driven by the driving assembly 24 and drives the adjustment ring 21 to rotate, and the positioning rod 222 reaches the other end of the positioning groove 14 from the starting end of the positioning groove 14, the position reached by the mold assembly 30 at this time is the processing point.

[0047] In this embodiment, the workbench 10 can provide stable support for the mold replacement device. By providing a mounting groove 11 and a drive hole 12 on the surface of the workbench 10, the adjustment mechanism 20 can be effectively placed to ensure that the adjustment mechanism 20 can effectively drive the mold to be replaced. By arranging a support rod 13 above the workbench 10, it can provide effective support for the use of the fixing mechanism 40 and ensure its stability during use. The adjustment mechanism 20 can effectively drive multiple molds arranged above it to be intelligently replaced. Among them, the adjustment mechanism 20 includes an adjustment ring 21 that is rotatably arranged in the mounting groove 11. Under the action of the transmission assembly 22 and the drive assembly 24, it can effectively rotate in the mounting groove 11 and drive the mold above to be replaced. By arranging the transmission assembly 22 in the drive hole 12, it can effectively receive the power generated by the drive assembly 24 and transmit the driving force to the adjustment ring 21 to ensure smooth and precise rotation. By arranging the positioning cylinder 211 above the adjusting ring 21, it can effectively cooperate with the driving plate 23 arranged at the output end of the transmission assembly 22. Under the action of the driving assembly 24, the power can be effectively transmitted to the driving plate 23, so that the driving plate 23 applies the power to the outside of the positioning cylinder 211, and then drives the adjusting ring 21 to rotate through the positioning cylinder 211. By arranging the positioning block 212 on the adjusting ring 21, it can effectively provide stable support for the installation of the mold assembly 30, ensuring the stability of the mold when in use. Among them, the driving assembly 24 is the power source of the adjusting mechanism 20, and can provide enough power to drive the transmission assembly 22 to work. The mold assembly 30 is used for stamping the steel structure. By arranging the mold assembly 30 above the positioning block 212, the stability and accuracy of the mold assembly 30 during the replacement process are ensured. Among them, the mold assembly 30 includes a stamping lower die 31 and a stamping upper die 32. Through the cooperation of the upper die and the lower die, the stamping process is completed together, ensuring the quality and accuracy of the stamping process. The fixing mechanism 40 is used to fix the adjustment ring 21 on which the mold is placed, and can effectively drive the upper mold to separate from the lower mold, thereby completing the stamping process. Among them, the fixing mechanism 40 includes a fixing plate 41 fixedly arranged on the support rod 13, which can provide stable support for the driving hydraulic cylinder 42 and the fixed push rod 43, ensuring safety and stability during use. Among them, by fixing the driving hydraulic cylinder 42 in the fixing plate 41, and arranging a connecting plate 421 at its output end, and slidingly connecting with the stamping upper mold 32 through the connecting plate 421, the stamping upper mold 32 can be effectively driven to move, and cooperate with the stamping lower mold 31 to complete the stamping work. By arranging the fixed push rod 43 in the fixing plate 41, and arranging a fixer 431 at its output end, and driving the fixer 431 to lift and lower through the fixed push rod 43, it can effectively be slidably connected with the positioning cylinder 211, ensuring the stability of the mold assembly 30 after the replacement is completed, and providing stable support for the use of the mold.

[0048] like Figure 3 , Figure 4 As shown, a positioning groove 14 is also provided on the workbench 10, which can provide a stable limit and guide channel, effectively control the range of motion of the transmission assembly 22, and prevent it from being offset or misplaced during use. By slidingly connecting the positioning rod 222 in the transmission assembly 22 with the positioning groove 14, under the drive of the driving assembly 24, the movement of the transmission assembly 22 can be effectively guided and limited to ensure stability and accuracy during the transmission process. Among them, the transmission rod 221 in the transmission assembly 22 is rotatably connected to the driving hole 12 to ensure the stability of the transmission assembly 22 during transmission, and can be transmitted with the transmission rod 221 as the center. Specifically, a control sensor 141 is provided at both ends of the positioning groove 14 to monitor the position of the positioning rod 222, and the rotation of the drive plate 23 is controlled by the position of the positioning rod 222.

[0049] like Figure 7 , Figure 8 As shown, by arranging a rotating bearing 223 on the transmission rod 221 and fixing the rotating bearing 223 with the workbench 10, the stability and accuracy of the transmission rod 221 during rotation can be ensured, and the transmission rod 221 can be effectively arranged in the driving hole 12 to ensure stability during use. At the same time, the friction and wear of the transmission rod 221 during rotation can be reduced, and the service life of the equipment can be extended. By arranging a transmission gear 224 at the bottom of the transmission rod 221, by cooperating with the driving assembly 24, the power can be effectively received from the driving assembly 24, and the transmission rod 221 can be driven to rotate, thereby realizing effective transmission of power. By arranging a transmission plate 225 at the other end of the transmission rod 221, the power transmitted by the transmission rod 221 can be effectively received, and the positioning rod 222 arranged at the bottom of the transmission plate 225 can be driven to rotate. By setting the transmission plate 225, the positioning rod 222 can be effectively driven and matched with the positioning groove 14. By opening the mounting hole 226 on the transmission plate 225 , the driving source of the driving plate 23 can be effectively placed, thereby ensuring the safety of the driving plate 23 in use.

[0050] like Figure 4 , Figure 8 As shown, by setting the driving plate 23 at the output end of the driving motor 231, the position of the driving plate 23 can be effectively controlled by the forward and reverse rotation of the driving motor 231, ensuring that the positioning cylinder 211 can be effectively driven. By fixing the driving motor 231 in the mounting hole 226, it is ensured that it is stable during use. Among them, the driving motor 231 is electrically connected to the control sensor 141 set in the positioning groove 14. By monitoring the position of the positioning rod 222 through the control sensor 141, a control signal can be effectively sent to the driving motor 231, thereby controlling the driving motor 231 to rotate forward and reverse.

[0051] like Figure 7 , Figure 8 As shown, by arranging the guide plate 241 at the bottom of the workbench 10, the driving rack 242 can be effectively guided and restricted to move, and the displacement or dislocation can be prevented when the meshing action is performed. By sliding the driving rack 242 in the guide plate 241 and arranging it at the output end of the driving push rod 243, the power generated by the driving push rod 243 can be effectively received, and it can move smoothly and accurately in the guide plate 241. Among them, the driving rack 242 also serves as a transmission element, and can transmit power to the transmission gear 224 by meshing with the transmission gear 224, ensuring the smoothness and accuracy of power transmission. By fixing the driving push rod 243 at the bottom of the workbench 10, the stability of power generation can be ensured, and it is ensured that there is enough power to drive the driving rack 242 to move.

[0052] In this embodiment, specifically, when the positioning rod 222 is at the starting end of the positioning groove 14, this is the starting point of the device. At this time, the control sensor 141 will send a control signal to the drive motor 231, thereby controlling the drive motor 231 to perform forward transmission, thereby driving the drive plate 23, so that the drive plate 23 acts on the outside of the positioning cylinder 211. When the driving push rod 243 is working, it drives the drive rack 242 to slide in the guide plate 241, and transmits power to the transmission gear 224 through meshing, driving the transmission gear 224 to rotate. When the power is transmitted to the transmission rod 221 and the transmission plate 225 in sequence through the transmission gear 224, the transmission plate 225 will be driven to rotate along the transmission rod 221 as the center, thereby driving the drive plate 23 to apply the driving force to the outside of the positioning cylinder 211, and then driving the adjustment ring 21 to rotate in the installation groove 11, thereby driving the mold assembly 30 to rotate through the positioning block 212, so that the mold assembly 30 moves to the processing point, and completes the rapid replacement of the mold. When it moves to the processing point, the positioning rod 222 at the bottom of the transmission plate 225 is located at the other end of the positioning groove 14. At this time, the control sensor 141 that controls the reverse rotation of the drive motor 231 sends a signal to the drive motor 231, driving the drive plate 23 to fold and rotate it below the transmission plate 225. Subsequently, the drive push rod 243 is controlled to be recovered, so that the power is transmitted through the drive rack 242, so that the transmission assembly 22 completes the reverse reset, and the positioning rod 222 moves to the starting point in the positioning groove 14. At this time, the drive motor 231 is controlled again by the control sensor 141 to work, driving the drive plate 23 to move to the outside of the positioning cylinder 211. When the mold needs to be replaced again, the mold can be quickly replaced by starting the drive assembly 24.

[0053] like Figure 1 , Figure 3As shown, by fixing a plurality of mold assemblies 30 above a plurality of positioning blocks 212, it is ensured that the mold assembly 30 can be effectively driven by the positioning blocks 212. Among them, a plurality of positioning blocks 212 and a plurality of positioning cylinders 211 are respectively arranged along the center array of the adjustment ring 21, to ensure the uniform distribution of the positioning cylinders 211 and the positioning blocks 212, thereby achieving uniform force on the adjustment ring 21 and ensuring the stability of the distribution of the mold assembly 30. Among them, the angle between the positioning block 212 and the positioning cylinder 211 is 60° to ensure that when the positioning cylinder 211 is driven, the positioning block 212 and the mold assembly 30 are effectively driven to move to the processing point, and the stamping work of the mold is realized by cooperating with the fixing mechanism 40. Specifically, the stamping lower die 31 can ensure the safety of the mold when the lower template 311 is fixedly connected to the positioning block 212. By arranging the concave die 312 on the lower template 311, the stamping effect can be effectively achieved.

[0054] Preferably, the upper mold plate 321 in the stamping upper mold 32 is slidably connected to the connecting plate 421 to ensure that the mold can be effectively separated. By fixing a positioning pin 322 above the upper mold plate 321, a stable positioning point can be provided for the upper mold plate 321 to prevent it from being offset or misaligned during the connection process, thereby ensuring a smooth connection. By providing a punch 323 at the bottom of the upper mold plate 321, and the punch 323 is adapted to the die 312, the accuracy of the stamping work is ensured, and the stamping work can be effectively completed according to the use requirements.

[0055] like Figure 5 , Fig.10 As shown, by opening a connection hole at the bottom of the connection plate 421, it can effectively cooperate with the positioning pin 322 to ensure the accuracy of fixing the stamping upper die 32. By setting a limit assembly 44 on the connection plate 421, when it is necessary to replace the mold, the stamping upper die 32 can be effectively fixed and limited to ensure that it can be separated from the stamping lower die 31, so that the stamping work is completed under the action of the driving hydraulic cylinder 42.

[0056] like Figure 6 , Figure 7 As shown, by fixing the slide rail 441 above the connecting plate 421, a guide path can be effectively provided for the movement of the slide plate 442, ensuring the stability of the slide plate 442 when moving, and preventing the slide plate 442 from being offset or misaligned during the movement. By setting the slide plate 442 above the slide rail 441 and fixing the slide plate 442 to the output end of the limit push rod 443, when the limit push rod 443 is driven, the slide plate 442 can be effectively driven to move along the slide rail 441. Ensure that the slide plate 442 can effectively drive the limit motor 444 and the limit plate 446 fixed at the bottom thereof to move, so as to ensure that different molds can be fixed.

[0057] Preferably, by fixing a plurality of limit motors 444 at the bottom of the sliding plate 442, and respectively arranging limit screws 445 at the output ends of the limit motors 444, power can be effectively provided and the limit screws 445 can be driven to rotate. Among them, by rotatably connecting the limit screws 445 with the limit plate 446, when the limit plate 446 is driven by the sliding plate 442 and moves to the bottom of the upper mold plate 321, the limit motor 444 can effectively drive the plurality of limit screws 445, so that the plurality of limit screws 445 act on the same limit plate 446 through threads, so that the limit plate 446 drives the stamping upper mold 32 to be fixed to the connecting plate 421.

[0058] In this embodiment, when the mold assembly 30 is driven to the processing point by the adjusting ring 21, the fixed push rod 43 located above the fixed plate 41 will be activated, driving the fixer 431 located at its output end to slide and connect with the positioning cylinder 211 on the adjusting ring 21, thereby fixing and positioning the adjusting ring 21 and the mold assembly 30, and completing the preliminary replacement of the mold. At this time, by controlling the driving hydraulic cylinder 42, the connecting plate 421 fixed at its output end is driven to descend, and the connecting plate 421 is slidably connected with the positioning pin 322 in the stamping upper mold 32 through the connecting hole opened at the bottom of the connecting plate 421. When the positioning pin 322 moves into the connecting hole, the limit push rod 443 will be activated accordingly, thereby driving the sliding plate 442 to move along the slide rail 441. When it moves to the designated position, the limiting motor 444 is controlled to rotate, driving the limiting screw 445 at its output end to rotate, and the limiting plate 446 is connected with the limiting plate 446 through the threaded connection, so that the limiting plate 446 drives the stamping upper die 32 and the connecting plate 421 to limit and fix. Ensure that the stamping upper die 32 is effectively separated from the stamping lower die 31, and at the same time, under the action of the driving hydraulic cylinder 42, the stamping upper die 32 is driven to complete the stamping work on the steel structure on the stamping lower die 31.

[0059] The working principle of the present invention is as follows: when punching steel structure, the mold assembly 30 is arranged above the positioning block 212 arranged on the adjusting ring 21. By controlling the driving assembly 24, the driving force is generated and transmitted to the transmission assembly 22, and the driving plate 23 arranged at its output end is driven by the transmission assembly 22, so that the driving plate 23 contacts the positioning cylinder 211 on the adjusting ring 21, and the adjusting ring 21 is driven by the power of the driving assembly 24, and rotates in the installation groove 11 opened on the workbench 10, thereby effectively driving the mold assembly 30 arranged on the positioning block 212 to be replaced. When the mold assembly 30 is driven by the adjusting mechanism 20 and moves to the processing point, the fixing mechanism 40 controls the driving hydraulic cylinder 42 and the fixing push rod 43, and drives the fixer 431 to connect with the positioning cylinder 211 on the adjusting ring 21 through the fixing push rod 43, so as to effectively fix the adjusting ring 21 and the mold assembly 30. At the same time, the driving hydraulic cylinder 42 drives the connecting plate 421 to connect with the stamping upper die 32 in the die assembly 30. At this time, through the action of the limit assembly 44, the stamping upper die 32 and the connecting plate 421 can be effectively fixed to ensure stability during use. Then, by controlling the driving hydraulic cylinder 42, the punch 323 in the stamping upper die 32 is effectively driven to move up and down for stamping, and interacts with the concave die 312 in the stamping lower die 31 fixed on the positioning block 212, so that the steel structure can be effectively stamped. When the number of times the die is used reaches a critical point, or the stamped finished product has defects, the upper die can be placed on the lower die by controlling the fixing mechanism 40. Then, the other die is driven to move to the processing point through the adjusting mechanism 20, and the die is fixed again by the fixing mechanism 40, and the stamping process can be effectively performed at the same time.
