Description

Technical Field

[0001] This utility model relates to the field of roller pressing equipment, and specifically to an automated quick mold changing device for roller pressing equipment. Background Technology

[0002] A roller press is a mechanical device that uses the pressure between two or more rollers to cause plastic deformation of materials under pressure. When the roller press is working, the two rollers rotate towards each other, maintaining a certain working gap between them. The material is fed into the gap between the two rollers from above with a certain pressure, and moves downward as the rollers rotate to complete the plastic deformation. The mold changing device is a device in the roller press used to quickly change molds, such as pressure rollers. The mold changing device enables quick and safe mold replacement, reduces mold changing time, and reduces labor intensity.

[0003] Existing mold changing devices require manual handling and installation of the mold frame during mold changing in roller pressing equipment. This method is slow, labor-intensive, and leads to increased downtime and reduced production efficiency. Furthermore, the lack of automated and rapid mold changing capabilities in roller pressing equipment can cause inconsistencies in the mold frame due to manual adjustments, affecting the subsequent processing accuracy and stability of the roller pressing equipment.

[0004] Therefore, it is necessary to invent an automated quick mold changing device for roller pressing equipment to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automated quick-change die changing device for roller pressing equipment. Through quick-installation slots, quick-installation blocks, side slots, internal locking slots, screws, threaded sleeves, worm gears, and worm shafts, a rotating rod drives multiple sets of worm gears and worm shafts to mesh and rotate, simultaneously completing the rapid replacement of multiple roller pressing die frames. This shortens the overall die changing time. Furthermore, the quick-release and quick-installation of multiple roller pressing die frames, along with the coordinated operation of the threaded sleeves and side slots, ensures the stability of the roller pressing die frames during roller pressing after die changing and installation. This automated quick-change reduces the skill requirements of operators, minimizes manual operation steps, and improves efficiency. The overall work efficiency is improved without interfering with the normal use of the subsequent roller pressing equipment. This solves the problem that in the existing mold changing device, manual handling and installation of the mold frame are required during mold changing. This method is slow, labor-intensive, and leads to increased downtime and reduced production efficiency. Furthermore, the lack of automated and rapid mold changing capabilities in roller pressing equipment under long-term use can cause inconsistencies in the mold frame due to manual adjustments, affecting the subsequent processing accuracy and stability of the roller pressing equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated rapid die-changing device for a roller pressing equipment, comprising a roller pressing die-changing base for supporting the main body of the roller pressing;

[0007] The quick-release slots are all located above the roller pressing die changing base, and are used to embed quick-release blocks inside. The quick-release blocks have side slots on their outside. A roller pressing die frame is fixedly installed above the quick-release blocks.

[0008] An inner locking groove is provided inside the roller pressing die changing base to provide die changing space. A screw is rotatably connected inside the inner locking groove, and a threaded sleeve is rotatably connected outside the screw. A turbine is fixedly installed at the front end of the screw.

[0009] An external frame is fixedly installed outside the roller press die changing base for externally mounting a servo motor. A rotating rod is fixedly installed at the output end of the servo motor, and a worm gear is fixedly installed on the outside of the rotating rod. A front roller press die changing frame is embedded on the upper left side of the roller press die changing base.

[0010] Preferably, the outer surface of the roller pressing die changing base is provided with a positioning slot, the positioning slot is inlaid with a positioning block, and a transparent protective cover is fixedly installed on the outside of the positioning block.

[0011] Preferably, the positioning block fixedly installed on the outside of the transparent protective cover engages with the positioning slot opened on the outside of the roller pressing mold changing seat, and the positioning block and the positioning slot are used in conjunction.

[0012] Preferably, an adjusting block is slidably connected inside the roller pressing mold frame, a lower roller is rotatably connected outside the adjusting block, and an upper roller is rotatably connected inside the roller pressing mold frame.

[0013] Preferably, the threaded sleeve is threadedly connected to the screw, and the two threads on the screw are opposite.

[0014] Preferably, the threaded sleeve is provided with sliders on both outer sides, and the threaded sleeve slides within the inner locking groove.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This utility model includes a quick-release groove, a quick-release block, a side slot, an inner locking groove, a screw, threaded sleeves, a worm gear, and a worm. When using this mold-changing device, due to the large overall weight of the roller die frame, during mold changing, the roller die frame can be inserted into the quick-release groove on the roller die-changing base via the quick-release block using an external lifting tool. Then, the rotating rod drives the worm gear to rotate, and the worm gear, which meshes with the worm gear, also drives the screw to rotate. At this time, the two threaded sleeves on the screw are close together in the middle. When the screw rotates, the threads at both ends of the screw are opposite, which will cause the threaded sleeves to separate. During the movement of the threaded sleeves in the inner locking groove, they are limited and slid within the inner locking groove by the sliders on both sides. Thus, the threaded sleeves are inserted into the quick-release block under the drive of the screw. The side slot allows for quick-installation and self-locking of the roll forming die frame. Disassembly is also possible by simply rotating the screw in the opposite direction, allowing the die frame to be removed via an external lifting device. This automated and rapid die-changing capability allows the rotating rod to drive multiple sets of worm gears and turbines to mesh and rotate, simultaneously enabling the rapid replacement of multiple roll forming dies. This shortens the overall die-changing time. Furthermore, the quick-installation and disassembly of multiple roll forming dies, along with the coordinated operation of the threaded sleeve and side slot, ensures the stability of the roll forming die frame during roll forming after installation. This automated and rapid die-changing reduces the skill requirements for operators, minimizes manual operations, improves overall work efficiency, and does not disrupt the normal operation of subsequent roll forming equipment.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 An automated quick die-changing device for a roller pressing equipment is shown, including a roller pressing die-changing base 1, which is used to support the main body of the roller pressing.

[0027] The quick-release slots 5 are all opened above the roller pressing die changing base 1, and are used to embed quick-release blocks 6 inside. The quick-release blocks 6 are provided with side slots 7 on the outside. The roller pressing die frame 8 is fixedly installed above the quick-release blocks 6.

[0028] The inner locking groove 12 is located inside the roller pressing mold changing base 1 to provide mold changing space. The inner locking groove 12 is rotatably connected to the screw 13, and the screw 13 is rotatably connected to the threaded sleeve 14. The front end of the screw 13 is fixedly installed with a turbine 15.

[0029] An external bracket 16 is fixedly mounted on the outside of the roller pressing die changing base 1 for externally mounting a servo motor 17. A rotating rod 18 is fixedly mounted on the output end of the servo motor 17, and worm gears 19 are fixedly mounted on the outside of the rotating rod 18. A front roller pressing die frame 20 is embedded on the upper left side of the roller pressing die changing base 1. The roller pressing die frame 8 is inserted into the quick-release slot 5 on the roller pressing die changing base 1 via a quick-release block 6. Then, the rotating rod 18 drives the worm gear 19 to rotate, and a turbine 15 meshes with the worm gear 19. Similarly, the screw 13 is rotated, and the two threaded sleeves 14 on the screw 13 are close together in the middle. When the screw 13 rotates, the two threads on the screw 13 are opposite, which will cause the threaded sleeves 14 to separate from each other. As the threaded sleeves 14 move in the inner locking groove 12, they are limited and slid in the inner locking groove 12 by the sliders on both sides. In this way, the threaded sleeves 14 are inserted into the side slots 7 of the quick-release block 6 under the drive of the screw 13, thereby completing the quick-release self-locking of the roller pressing mold frame 8.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, a positioning slot 2 is provided on the outer surface of the roller pressing die changing base 1. A positioning block 3 is embedded inside the positioning slot 2. A transparent protective cover 4 is fixedly installed on the outside of the positioning block 3. The roller pressing die frame 8 is inserted into the quick-installation slot 5 on the roller pressing die changing base 1 through a quick-installation block 6 to assist in the installation. The positioning block 3 fixedly installed on the outside of the transparent protective cover 4 is engaged with the positioning slot 2 on the outside of the roller pressing die changing base 1. The positioning block 3 and the positioning slot 2 work together. The transparent protective cover 4 is used to provide a certain degree of protection for the rotating turbine 15 and worm gear 19. An adjusting block 9 is slidably connected inside the roller pressing die frame 8. A lower roller pressing wheel 10 is rotatably connected to the outside of the adjusting block 9. An upper roller pressing wheel 11 is rotatably connected inside the roller pressing die frame 8. The gap between the lower roller pressing wheel 10 and the upper roller pressing wheel 11 of the roller pressing die frame 8 can be adjusted to assist the roller pressing equipment in completing the roller pressing work.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the threaded sleeve 14 is threadedly connected to the screw 13. The two threads on the screw 13 are opposite. During the movement of the threaded sleeve 14 in the inner locking groove 12, it slides within the inner locking groove 12 by the sliders on both sides. In this way, the threaded sleeve 14 is inserted into the side slot 7 of the quick-release block 6 under the drive of the screw 13, thereby completing the quick-release self-locking of the roller mold frame 8. The outer sides of the threaded sleeve 14 are provided with sliders. The threaded sleeve 14 slides within the inner locking groove 12. The overall structure of the threaded sleeve 14 is simple and easy to operate. If a fault occurs, it is convenient for maintenance personnel to maintain or replace it in a timely manner.

[0032] The working principle of this practical device is as follows: First, when the automatic quick mold changing device of the roller pressing equipment is used, the external power supply is connected. Due to the large overall weight of the roller pressing mold frame 8, during mold changing, the roller pressing mold frame 8 can be inserted into the quick-release slot 5 on the roller pressing mold changing base 1 through the quick-release block 6 using an external lifting tool. Then, after multiple roller pressing mold frames 8 are inserted into the roller pressing mold changing base 1, the switch of the servo motor 17 is turned on, causing the rotating rod 18 to drive the worm gear 19 to rotate. At this time, the worm gear 19 is engaged with the worm gear 19. Wheel 15 also drives screw 13 to rotate. Then, the two threaded sleeves 14 on screw 13 move closer together. As screw 13 rotates, the two threads on screw 13 are opposite, causing the threaded sleeves 14 to separate. During the movement of the inner locking groove 12, the threaded sleeves 14 slide within the inner locking groove 12 via sliders on both sides. Thus, driven by screw 13, the threaded sleeves 14 are inserted into the side slots 7 of the quick-release block 6, thereby completing the quick-release self-locking of the roller pressing mold frame 8. Subsequently, when needed... During disassembly, simply follow the above steps to rotate the screw 13 in the opposite direction. The roll forming die 8 can then be removed using an external lifting device, enabling automated and rapid die changing. This design allows the rotating rod 18 to drive multiple sets of worm gears 19 and turbines 15 to mesh and rotate, simultaneously completing the rapid replacement of multiple roll forming die 8, thus shortening the overall die changing time. Furthermore, the quick disassembly and assembly of multiple roll forming die 8, along with the coordinated operation of the threaded sleeve 14 and the side slot 7, ensures the stability of the roll forming die 8 during roll forming after die changing and installation. After the die changing is completed, the workpiece can be rolled sequentially through the upper roll forming rollers 11 and lower roll forming rollers 10 of multiple roll forming die 8, and then through the front roll forming die 20 to finally complete the roll forming production. After completing the installation and use of the automated rapid die changing device for all roll forming equipment according to the above operations, turn off the switch of the servo motor 17. If not used for a long time, simply disconnect the external power supply. This completes the usage process of the automated rapid die changing device for the roll forming equipment.

[0033] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
