Description

Technical Field

[0001] This invention relates to the field of tertiary air damper stamping technology, and in particular to a tertiary air damper stamping mold and method. Background Technology

[0002] The tertiary air damper is a key component of the cement kiln calcination system, located within the tertiary air duct. This duct connects the cement kiln and the precalciner. Tertiary air enables the combustion of pulverized coal in the precalciner, and the damper controls the ventilation volume per unit time. The amount of ventilation directly affects the precalciner's decomposition efficiency and the cement kiln's overall ventilation, thus impacting cement quality and production efficiency. Therefore, the tertiary air damper largely determines the normal operation of the entire cement kiln calcination system. Domestically, heat-resistant steel disc dampers, heat-resistant steel refractory dampers, and heat-resistant steel castable dampers are commonly used. Common faults include damper deformation and jamming, refractory spalling and wear, and damper breakage. To ensure the proper functioning of the tertiary air damper, domestically developed tertiary air dampers have been developed, significantly increasing their service life.

[0003] When demolding existing tertiary air dampers, due to the large friction between the formed tertiary air damper and the mold, it is usually necessary to use external force to knock them out. During the knocking demolding process, the flatness of the surface of the tertiary air damper is easily damaged, which affects the quality of the product. At the same time, the mold is prone to displacement during the stamping process, which causes stamping displacement and affects the stamping operation. Summary of the Invention

[0004] This invention discloses a stamping mold and method for a tertiary air damper, aiming to solve the technical problems in the background art where, because the tertiary air damper is a brittle material, the surface flatness of the tertiary air damper is easily damaged during the demolding process, and the mold is prone to displacement during the stamping process, resulting in stamping deviation and thus affecting product quality.

[0005] This invention proposes a stamping die for a tertiary air damper, comprising a tooling support frame. A stamping platform is fixedly connected to the upper side of the tooling support frame, and a stamping auxiliary module is provided on the stamping platform. The stamping auxiliary module includes a fixing plate and two mounting plates. Two limiting plates are bolted to the top of the stamping platform, and a mold body is placed on the side of the two limiting plates. A blanking plate is placed inside the mold body. Two slides are provided on the stamping platform, and a guide rod is fixedly connected to the opposite side of each of the two slides. The guide rod is slidably connected to an adjusting slide block. The adjusting slide block and the opposite side of the slide rail are fixedly connected to the same hydraulic spring. The sides of the two mounting plates are fixedly connected to clamping frames. The sides of the two clamping frames are provided with arc-shaped grooves. Arc-shaped slide plates are slidably connected inside the two arc-shaped grooves. Semi-circular slide blocks are fixedly connected to the arc surfaces of the two arc-shaped slide blocks. Arc-shaped grooves are provided on the sides of the multiple semi-circular slide blocks. Arc-shaped slide plates are slidably connected inside the multiple arc-shaped grooves. Clamping seats are fixedly connected to the arc surfaces of the multiple arc-shaped slide plates.

[0006] In a preferred embodiment, tooling support rods are bolted to the top of both adjusting slides, and one circular hole is equally spaced on one side of each of the two tooling support rods. Limiting cylinders are slidably connected inside the multiple circular holes. One side of the limiting cylinder is fixedly connected to one side of the mounting plate. Buffer springs are fixedly connected at equal distances to the opposite side of the mounting plate and the tooling support rods. The buffer springs are located outside the limiting cylinders.

[0007] In a preferred embodiment, the stamping platform has a slot, and a lead screw nut slider is slidably connected inside the slot. One side of the lead screw nut slider is fixedly connected to one side of the adjusting slide. A second circular hole is formed on one side of the slot, and a lead screw is connected inside the second circular hole through a bearing. A lead screw motor is fixedly connected to one side of the stamping platform, and the drive end of the lead screw motor is connected to one end of the lead screw through a coupling.

[0008] In a preferred embodiment, U-shaped support plates are bolted to the bottom of the stamping platform at equal intervals, and each of the U-shaped support plates has an installation opening on one side. Each of the installation openings has a limiting frame fixedly connected inside, and each of the limiting frames has a slidably connected material feeding push rod inside. Each of the material feeding push rods has an impact seat fixedly connected to one end. Each of the stamping platforms has through holes at equal intervals on one side, and the impact seat passes through the through holes and abuts against one side of the material feeding plate.

[0009] In a preferred embodiment, each of the plurality of feeding push rods is fixedly connected to a linkage rack at one end, and each of the plurality of linkage racks is fixedly connected to a return spring on the opposite side of the tooling support frame. Each of the plurality of fixed plates has a circular hole three on its side, and the interior of each of the two opposite circular holes three is connected to the same rotating rod through a bearing. The exterior of each of the two rotating rods is fixedly connected to two semi-circular gears, the tooth blocks of which mesh with the linkage rack. Two drive motors are fixedly connected to the tooling support frame, and the drive ends of the drive motors are connected to one side of the rotating rod through a coupling.

[0010] With the addition of a stamping auxiliary module, during the tertiary air damper stamping process, the mold body is first placed above the stamping platform and abuts against the limiting plate. Then, the lead screw motor is started, driving the lead screw nut slider to move the adjusting slide block within the slideway. The clamping seat on the clamping frame located on the adjusting slide block abuts against the outside of the mold body. At this time, the clamping seat slides within the arc-shaped groove two via the arc-shaped slide plate two, and the semi-circular slide block slides within the arc-shaped groove one via the arc-shaped slide plate one. This allows the clamping seat to adaptively clamp and fix the arc-shaped surface of the mold body, ensuring the mold body remains static during stamping and facilitating quick mold body replacement. After stamping, the mold body is then activated... The drive motor rotates the rotating rod, causing the toothed end of the semi-circular gear to mesh with the linkage rack. At this time, the material ejector moves downward inside the limiting circular frame, and the return spring is simultaneously compressed. When the semi-circular gear separates from the linkage rack, the return spring rebounds quickly, causing the impact seat on the material ejector to impact the material ejector plate below the mold body. This ensures uniform force distribution during the demolding process of the tertiary air damper, guaranteeing demolding quality. Through the stamping auxiliary module, the surface of the tertiary air damper is subjected to uniform force during the knocking demolding process, preventing damage to the surface of the tertiary air damper. At the same time, it ensures that the mold is static during the stamping process, preventing stamping deviation and improving product quality.

[0011] In a preferred embodiment, hydraulic guide cylinders are fixedly connected at equal intervals on the stamping platform, and the external parts of the multiple hydraulic guide cylinders are movably connected to the same stamping lifting platform. One end of the multiple hydraulic guide cylinders is fixedly connected to the same tooling support seat. A cleaning module is provided on one side of the stamping lifting platform, and the cleaning module includes a support fixing frame.

[0012] In a preferred embodiment, two mounting ports are provided on one side of the support frame, and electric drive rods are fixedly connected inside both mounting ports. The driving ends of the two electric drive rods are fixedly connected to the same collection frame. Circular holes four are provided on both sides of the collection frame. The same rotating cylinder is connected inside the two circular holes four through bearings. A cleaning brush is fixedly connected to the outside of the rotating cylinder. A linkage gear is fixedly connected to one end of the rotating cylinder. Limiting rail one is bolted to one side of the collection frame. An adjusting gear is slidably connected inside limiting rail one. Limiting rail two is bolted to one side of the collection frame. A linkage slider is slidably connected inside limiting rail two. The linkage slider and the adjusting gear are fixedly connected to the same pushing and translating frame.

[0013] In a preferred embodiment, a mounting base is fixedly connected to one side of the collection frame, and a universal motor is fixedly connected to one side of the mounting base. A rotating push rod is fixedly connected to the drive end of the universal motor. A circular hole five is provided on one side of the rotating push rod. A roller is connected to the inside of the circular hole five through a bearing. The roller is slidably connected to the inside of the push and translate frame. A feeding opening and closing plate is connected to one side of the collection frame through a hinge.

[0014] By incorporating a cleaning module, during the stamping process of a reusable stamping lifting platform for pressing the mold body, an electric drive rod is activated while waiting for the pressing to complete. This drive rod moves a collection frame horizontally below the stamping lifting platform. Simultaneously, a universal motor is activated, causing one end of a rotating push rod to rotate in a circular motion. A roller is slidably connected inside the push-translation frame. As the rotating push rod moves in a circular motion, the roller drives the push-translation frame to move horizontally back and forth on limit rail one and limit rail two. This causes the adjusting gear on the push-translation frame to drive the linkage gear to rotate bidirectionally, thereby allowing the cleaning brush on the rotating cylinder to clean the stamping end of the stamping lifting platform. Impurities generated during cleaning are collected by the collection frame. The bidirectional rotation of the cleaning brush improves the cleaning effect, thus preventing residual impurities on the stamping lifting platform from affecting reuse and reducing production quality.

[0015] In a preferred embodiment, the stamping lifting platform has through-holes at equal intervals on one side, and compression springs are arranged in a ring inside each of the through-holes. The same U-shaped limiting frame is fixedly connected to one side of each of the compression springs on the same side. Circular holes are opened at equal intervals on both sides of the multiple U-shaped limiting frames. The interiors of two opposing circular holes are connected to the same ball bearing. The ball abuts against the outside of the hydraulic guide cylinder. Guide circular frames are fixedly connected at equal intervals on both sides of the stamping lifting platform. The same protective telescopic cylinder is fixedly connected to one side of each of the multiple guide circular frames located below the stamping lifting platform and one side of the stamping platform. The stamping body is mounted on the tooling support.

[0016] A method for using a tertiary air damper stamping die, comprising the following steps:

[0017] Step 1, during the three-stage air damper stamping process, firstly, the mold body is placed above the stamping platform and abuts against the limiting plate. Then, the lead screw motor is started, which drives the lead screw nut slider to move the adjusting slide inside the slide. The clamping seat on the clamping frame located on the adjusting slide abuts against the outside of the mold body. At this time, the clamping seat slides inside the arc groove 2 through the arc-shaped slide plate 2, and the semi-circular slide slides inside the arc groove 1 through the arc-shaped slide plate 1, so that the clamping seat adaptively clamps and fixes the arc surface of the mold body.

[0018] Step 2: After the stamping is completed, the drive motor is started, which drives the rotating rod to rotate, so that the tooth block end of the semi-circular gear meshes with the linkage rod. At this time, the feeding push rod moves down inside the limiting circle frame, and the return spring is squeezed at the same time.

[0019] Step 3: When the semi-circular gear separates from the linkage rack, the return spring rebounds quickly, causing the impact seat on the discharge push rod to impact the discharge plate below the mold body, so that the force is evenly distributed during the demolding process of the three-stage air damper.

[0020] As can be seen from the above, the tertiary air damper stamping mold provided by the present invention has the beneficial effects of ensuring uniform force on the surface of the tertiary air damper during the knocking and demolding process, avoiding damage to the surface of the tertiary air damper, and ensuring that the mold is static during the stamping process to avoid stamping deviation, thereby improving product quality.

Each of the U-shaped support plates 820 has an installation round opening on one side. Each of the installation round openings has a fixed limit frame 821 inside. Each of the limit frames 821 has a sliding push rod 822 inside. Each of the push rods 822 has an impact seat 823 fixedly connected to one end. Each of the stamping platform 2 has a through hole at equal intervals on one side. The impact seat 823 passes through the through hole and abuts against one side of the unloading plate 804.

Two drive motors 827 are fixedly connected to the tooling support frame 1. The drive end of the drive motor 827 is connected to one side of the rotating round rod 825 through a coupling.

[0042] In a specific application scenario, during the three-stage air damper stamping process, the mold body 802 is first placed above the stamping platform 2 and abuts against the limiting plate 801. Then, the lead screw motor 803 is started, which drives the lead screw 807, causing the lead screw nut slider 806 to move the adjusting slide 810 inside the slide rail 805. The clamping seat 819 on the clamping frame 815 located on the adjusting slide 810 abuts against the outside of the mold body 802. At this time, the clamping seat 819 slides inside the arc groove 2 via the arc-shaped slide plate 2 818, and the semi-circular slide 817 slides inside the arc groove 1 via the arc-shaped slide plate 1 816, thereby making the clamping seat... The 819 adaptive clamps and fixes the arc surface of the mold body 802. After the stamping is completed, the drive motor 827 is started, and the drive motor 827 drives the rotating rod 825 to rotate, so that the tooth block end of the semi-circular gear 826 meshes with the linkage rod 824. At this time, the unloading push rod 822 moves down inside the limiting circular frame 821, and the return spring 828 is squeezed at the same time. When the semi-circular gear 826 separates from the linkage rod 824, the return spring 828 rebounds quickly, so that the impact seat 823 on the unloading push rod 822 impacts the unloading plate 804 below the mold body 802, so that the force is uniform during the demolding process of the three-stage air damper.

One end of multiple hydraulic guide cylinders 3 is fixedly connected to the same tooling support seat 6. A cleaning module 9 is provided on one side of the stamping lifting platform 5. The cleaning module 9 includes a support fixing frame 901.

[0044] Reference Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 , Figure 10 and Figure 11 Two mounting ports are provided on one side of the support frame 901, and electric drive rods 902 are fixedly connected inside the two mounting ports. The driving ends of the two electric drive rods 902 are fixedly connected to the same collection frame 903. Two round holes 4 are provided on both sides of the collection frame 903. The same rotating cylinder 905 is connected inside the two round holes 4 through bearings. A cleaning brush cylinder 904 is fixedly connected to the outside of the rotating cylinder 905. A linkage gear 906 is fixedly connected to one end of the rotating cylinder 905. A limit track 1 907 is bolted to one side of the collection frame 903.

A linkage slider 912 is slidably connected inside the limit track 2 910. The linkage slider 912 and one side of the adjusting gear 908 are fixedly connected to the same push translation frame 909.

A feeding opening and closing plate 911 is connected to one side of the collection frame 903 through a hinge.

[0046] In a specific application scenario, when the stamping lifting platform 5 is repeatedly used to stamp the mold body 802, during the waiting period for stamping, the electric drive rod 902 is activated. The electric drive rod 902 drives the collection frame 903 to move horizontally below the stamping lifting platform 5. At the same time, the general motor 914 is activated. The general motor 914 drives one end of the rotating push rod 915 to rotate in a circle. The roller 916 is slidably connected to the inside of the push translation frame 909. When the rotating push rod 915 moves in a circle, the roller 916 drives the push translation frame 909 to move horizontally back and forth on the first limit track 907 and the second limit track 910. This causes the adjusting gear 908 on the push translation frame 909 to drive the linkage gear 906 to rotate in both directions. This causes the cleaning brush 904 on the rotating cylinder 905 to clean the stamping end of the stamping lifting platform 5. The impurities generated during cleaning are collected by the collection frame 903.

[0048] A method for using a tertiary air damper stamping die, comprising the following steps:

[0049] Step 1, during the three-stage air damper stamping process, firstly, the mold body 802 is placed above the stamping platform 2 and abuts against the limiting plate 801. Then, the lead screw motor 803 is started, which drives the lead screw 807, causing the lead screw nut slider 806 to move the adjusting slide 810 inside the slide rail 805. The clamping seat 819 on the clamping frame 815 located on the adjusting slide 810 abuts against the outside of the mold body 802. At this time, the clamping seat 819 slides inside the arc groove 2 through the arc-shaped slide plate 2 818, and the semi-circular slide 817 slides inside the arc groove 1 through the arc-shaped slide plate 1 816, so that the clamping seat 819 adaptively clamps and fixes the arc surface of the mold body 802.

[0050] Step 2: After the stamping is completed, the drive motor 827 is started. The drive motor 827 drives the rotating rod 825 to rotate, so that the tooth block end of the semi-circular gear 826 meshes with the linkage rod 824. At this time, the feeding push rod 822 moves down inside the limiting circular frame 821, and the return spring 828 is squeezed at the same time.

[0051] Step 3: When the semi-circular gear 826 separates from the linkage rack 824, the return spring 828 rebounds quickly, causing the impact seat 823 on the unloading push rod 822 to impact the unloading plate 804 below the mold body 802, so that the force is evenly distributed during the demolding process of the three-stage air damper.

[0052] Working principle: During the three-stage air damper stamping process, the mold body 802 is first placed above the stamping platform 2 and abuts against the limiting plate 801. Then, the lead screw motor 803 is started, which drives the lead screw 807, causing the lead screw nut slider 806 to move the adjusting slide 810 inside the slide rail 805. The clamping seat 819 on the clamping frame 815 located on the adjusting slide 810 abuts against the outside of the mold body 802. At this time, the clamping seat 819 slides inside the arc-shaped groove through the arc-shaped slide plate 818. The slide block 817 slides inside the arc-shaped groove via the arc-shaped sliding plate 816, thereby allowing the clamping seat 819 to adaptively clamp and fix the arc-shaped surface of the mold body 802. When the stamping lifting platform 5 is repeatedly used to stamp the mold body 802, during the waiting period for stamping, the electric drive rod 902 is activated, which drives the collecting frame 903 to move horizontally below the stamping lifting platform 5. At the same time, the general-purpose motor 914 is activated, which drives one end of the rotating push rod 915 to rotate in a circular motion, and the roller 916... The sliding connection is inside the push-translation frame 909. When the rotating push rod 915 rotates in a circular motion, the roller 916 drives the push-translation frame 909 to move horizontally back and forth on the first limit track 907 and the second limit track 910. This causes the adjusting gear 908 on the push-translation frame 909 to drive the linkage gear 906 to rotate in both directions. This causes the cleaning brush 904 on the rotating cylinder 905 to clean the stamping end of the stamping lifting platform 5. The impurities generated during cleaning are collected by the collection frame 903. After the stamping is completed, the drive is activated. Motor 827 drives the rotating rod 825 to rotate, thereby causing the tooth block end of the semi-circular gear 826 to mesh with the linkage rack 824. At this time, the unloading push rod 822 moves down inside the limiting circular frame 821, and the return spring 828 is simultaneously compressed. When the semi-circular gear 826 separates from the linkage rack 824, the return spring 828 rebounds quickly, thereby causing the impact seat 823 on the unloading push rod 822 to impact the unloading plate 804 below the mold body 802, so that the force is evenly distributed during the demolding process of the three-stage air damper.
