Description

Technical Field

[0001] The present invention belongs to the technical field of valve disc production, and specifically relates to a production device for a labyrinth valve disc. Background Art

[0002] In the field of labyrinth valve manufacturing, as a key component, the production process of the labyrinth valve disc has attracted much attention. With the continuous improvement of valve performance requirements in various industries, the traditional valve disc production method is difficult to meet the high-precision and high-efficiency needs. The existing production mode introduces advanced automation concepts. First, the raw material feeding system precisely controls and stably transports the plate to the milling cutter unit, where it is finely processed according to the preset shape to initially shape the valve disc contour. Then, it enters the stamping and forming module, and the stamping machine operates according to the program for stamping.

[0003] Although the existing stamping dies can meet the basic production requirements, their disadvantages gradually emerge during long-term high-intensity use. Due to the frequent stamping of labyrinth valve discs, the die cutting edges continuously bear huge pressure and friction. The high-load operation causes the cutting edges to wear increasingly severely, and the sharpness drops sharply. When the wear reaches a certain level, the material cannot be accurately and neatly cut during stamping, and burrs will be generated on the inner side of the valve disc. These burrs not only damage the surface flatness and smoothness of the valve disc itself but also make it difficult for adjacent valve discs to fit tightly after assembly. The tiny gaps become channels for medium leakage, seriously weakening the valve sealing performance and frequently causing pipeline system failures, interfering with the normal production process. Therefore, improvement and optimization are needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a production device for a labyrinth valve disc to solve the problems raised in the above background art.

On the top of the first bearing plate a fixed support frame is fixedly installed, on the top of the fixed support frame a stamping and deburring assembly is fixedly installed. The stamping and deburring assembly includes a buffer pad fixedly installed on the top of the fixed support frame. Both the buffer pad and the fixed support frame are provided with a first communication groove. A fixed rod is fixedly installed between the buffer pad and the second bearing plate. The lower die assembly, the clamping assembly and the second bearing plate are provided with communication grooves and are interconnected. A disc is slidably installed on the outer surface of the fixed rod. Extension bumps are fixedly installed on the top of the disc and the bottom side of the second bearing plate. A scraper is fixedly installed on the top of the disc and is located inside the extension bumps. Inside the third bearing plate a cylinder is fixedly installed, and on the output end of the cylinder a stamping upper die is fixedly installed. On both sides of the stamping upper die a transmission rod is fixedly installed and the transmission rod penetrates through the second bearing plate. Inside the two transmission rods a transmission block is fixedly installed, and on the top of the transmission block a ejector rod is fixedly installed.

[0006] Preferably, the clamping assembly includes a fixed bearing block fixedly installed on the top of the second bearing plate. On both sides of the outer surface of the fixed bearing block a chute is provided. Inside the chute a telescopic rod is fixedly installed, and at the other end of the telescopic rod a slider is fixedly installed. A first spring is fixedly connected between the slider and the inner wall of the chute and is movably sleeved on the outer surface of the telescopic rod. On the top of the slider a connecting block is fixedly installed. Inside the connecting block a connecting rod is fixedly installed. Inside the connecting rod an arc-shaped clamping block is fixedly connected. The lower die assembly is clamped inside the two arc-shaped clamping blocks.

[0007] Preferably, the lower die assembly includes a lower die clamped inside the two arc-shaped clamping blocks. On the top of the lower die a labyrinth convex block is fixedly installed. Inside the arc-shaped clamping block an air bag is fixedly installed, and the air bag covers the inner wall of the arc-shaped clamping block.

[0008] Preferably, both ends of the fixed rod penetrate through the inside of the disc, and there are two groups of four fixed rods arranged in pairs.

[0009] Preferably, a second spring is fixedly connected between the two extension bumps and is movably sleeved on the outer surface of the scraper. The buffer pad is rectangular in shape, and the radius of the buffer pad is greater than the radius of the disc.

[0010] Preferably, the fixed support frame is C-shaped, and the fixed support frame is located between the transmission block and the second bearing plate.

[0011] Preferably, the extension bump is in an annular shape, and one end of the scraper extends inside the extension bump and the other end extends to the inside of another extension bump.

[0012] Preferably, a base is fixedly installed at the bottom of the first bearing plate, and the base is fixedly installed around the bottom of the first bearing plate.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. In the present invention, the driving rod drives the driving block to move upward, and then the driving block will drive the ejector rod to pass through the first communication groove and push the disc upward. Then the disc drives the extension bump and the scraper to pass through the communication groove upward. Then, while continuing to move upward, the plurality of scrapers are attached to the inner side of the stamped labyrinth valve disc to scrape off the burrs, and at the same time, the waste after stamping will also be taken out together, which is convenient for recycling. Compared with the traditional device, this device realizes the precise stamping of the center of the labyrinth valve disc through components such as the air cylinder and the stamping upper die. The distance sensor ensures that the stamping is just right. Secondly, after stamping, the stamping upper die rises to drive a series of components to act. The scraper can closely adhere to the inner side of the valve disc to effectively scrape off the burrs, so that the inner side of the labyrinth valve disc remains smooth. Moreover, the waste can be taken out together with the valve disc, which is convenient for recycling. It not only improves the processing efficiency, but also is beneficial to environmental protection, reducing the cumbersome steps of waste cleaning. The whole process is coherent and efficient, taking into account the processing quality and the convenience of subsequent processing.

[0015] 2. In the present invention, an external force is used to squeeze the arc-shaped clamping block to one side, and then the arc-shaped clamping block will conduct the acting force to the connecting rod. After that, the connecting rod will conduct the force to the connecting block, and the connecting block will drive the slider to slide inside the sliding groove. At the same time, the sliding of the slider will cause the first spring to generate elastic deformation. At this time, the telescopic rod can limit the first spring. Then the lower die assembly is placed inside the two arc-shaped clamping blocks, and at the same time, the external force disappears. At this time, due to the elastic recovery of the two first springs, the arc-shaped clamping blocks are driven to fixedly clamp the lower die assembly. Compared with the traditional device, on the one hand, it uses a clever mechanical conduction design, and the acting force is sequentially transmitted through components such as the arc-shaped clamping block, the connecting rod, and the connecting block to realize the cooperation between the sliding of the slider and the elastic deformation of the first spring, making the replacement convenient. On the other hand, the limiting effect of the telescopic rod ensures the controllability of the elastic deformation and avoids malfunction caused by excessive deformation. Finally, the lower die assembly is fixedly clamped by relying on the elastic recovery of the first spring, which is not only stable and reliable, but also convenient and fast, greatly improving the replacement efficiency, reducing the equipment downtime, and enhancing the overall production efficiency.

[0016] 3. In the present invention, the labyrinth valve disc processed by the milling cutter unit is clamped and fitted with the labyrinth bump. Compared with the traditional device, firstly, the labyrinth valve disc processed by the milling cutter unit is accurately clamped and fitted with the labyrinth bump, ensuring the alignment accuracy of processing from the source. Secondly, by cleverly utilizing the height difference of the components, with the design that the arc-shaped clamping block and the airbag inside it are higher than the lower mold, the airbag applies a stable clamping force to the valve disc, effectively preventing the valve disc from shifting during the deburring operation of the stamping deburring component, ensuring the continuity and accuracy of the processing process. Thirdly, the clamping and fitting and the clamping cooperate with each other, greatly enhancing the stability during stamping, reducing the defective rate, and improving the overall production quality and efficiency.

DETAILED DESCRIPTION OF THE INVENTION

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 to 7 shown, an apparatus for producing a labyrinth valve vane according to an embodiment of the present invention includes a first carrier plate 1. A support rod 2 is fixedly installed on the top of the first carrier plate 1. A second carrier plate 3 is fixedly installed on the outer surface of the support rod 2. A third carrier plate 4 is fixedly installed on the top of the support rod 2. A clamping assembly 5 is fixedly installed on the top of the second carrier plate 3. A lower die assembly 8 is clamped above the clamping assembly 5. A fixed support frame 6 is fixedly installed on the top of the first carrier plate 1. A stamping and deburring assembly 7 is fixedly installed on the top of the fixed support frame 6. The stamping and deburring assembly 7 includes a buffer pad 701 fixedly installed on the top of the fixed support frame 6. The buffer pad 701 and the fixed support frame 6 are both provided with a first communication groove 702. A fixed rod 704 is fixedly installed between the buffer pad 701 and the second carrier plate 3. The lower die assembly 8, the clamping assembly 5 and the second carrier plate 3 are provided with a communication groove 708 and are interconnected. A disc 703 is slidably installed on the outer surface of the fixed rod 704. Extension bumps 705 are fixedly installed on the top of the disc 703 and the bottom side of the second carrier plate 3. A scraping blade 707 is fixedly installed on the top of the disc 703 and is located inside the extension bump 705. A cylinder 709 is fixedly installed inside the third carrier plate 4. An output end of the cylinder 709 is fixedly installed with a stamping upper die 710. Transmission rods 711 are fixedly installed on both sides of the stamping upper die 710 and the transmission rods 711 penetrate through the second carrier plate 3. A transmission block 712 is fixedly installed inside the two transmission rods 711. A ejector rod 713 is fixedly installed on the top of the transmission block 712.

[0027] When the staff place the processed labyrinth valve disc of the milling cutter unit above the lower die assembly 8, and then start the cylinder 709 through an external controller, the cylinder 709 will drive the output end to press the stamping upper die 710 downward. Then, since the size of the end of the stamping upper die 710 is the same as the size of the opening of the communication groove 708, and the communication grooves 708 opened in the lower die assembly 8, the clamping assembly 5 and the second bearing plate 3 are interconnected, the center of the labyrinth valve disc can be stamped. When the distance sensor reaches the set stamping completion distance, the stamping stops. Then, the stamping upper die 710 rises, and will drive the transmission block 712 to move upward through the transmission rod 711. Then, the transmission block 712 will drive the ejector rod 713 to push the disc 703 upward through the first communication groove 702. Then, the disc 703 drives the extension lug 705 and the scraper 707 to pass through the communication groove 708 upward. Then, while continuing to move upward, the multiple scrapers 707 are attached to the inner side of the stamped labyrinth valve disc to scrape off the burrs. At the same time, the stamping waste will also be taken out together, which is convenient for recycling. Among them, the buffer pad 701 and the first communication groove 702 opened in the fixed support frame 6 are interconnected.

[0028] The transmission rod 711 drives the transmission block 712 to move upward. Then, the transmission block 712 will drive the ejector rod 713 to push the disc 703 upward through the first communication groove 702. Then, the disc 703 drives the extension lug 705 and the scraper 707 to pass through the communication groove 708 upward. Then, while continuing to move upward, the multiple scrapers 707 are attached to the inner side of the stamped labyrinth valve disc to scrape off the burrs. At the same time, the stamping waste will also be taken out together, which is convenient for recycling. Compared with the traditional device, this device realizes the precise stamping of the center of the labyrinth valve disc through components such as the cylinder 709 and the stamping upper die 710. The distance sensor ensures that the stamping is just right. Secondly, after the stamping is completed, the stamping upper die 710 rises to drive a series of components to act. The scraper 707 can closely adhere to the inner side of the valve disc to effectively scrape off the burrs, so that the inner side of the labyrinth valve disc remains smooth. Moreover, the waste can be taken out together with the valve disc, which is convenient for recycling. It not only improves the processing efficiency, but also is beneficial to environmental protection, reducing the cumbersome steps of waste cleaning. The whole process is coherent and efficient, taking into account the processing quality and the convenience of subsequent processing.

[0029] Among them, the clamping assembly 5 includes a fixed supporting block 501 fixedly installed on the top of the second supporting plate 3, and sliding grooves 502 are opened on both sides of the outer surface of the fixed supporting block 501. A telescopic rod 503 is fixedly installed on the inner side of the sliding groove 502, and a slider 505 is fixedly installed on the other end of the telescopic rod 503. A first spring 504 is fixedly connected between the slider 505 and the inner wall of the sliding groove 502, and is movably sleeved on the outer surface of the telescopic rod 503. A connecting block 506 is fixedly installed on the top of the slider 505, and a connecting rod 507 is fixedly installed on the inner side of the connecting block 506. An arc-shaped clamping block 508 is fixedly connected to the inner side of the connecting rod 507, and the inner sides of the two arc-shaped clamping blocks 508 clamp the lower mold assembly 8.

[0030] When it is necessary to replace a different lower mold assembly 8, the arc clamping block 508 is squeezed to one side by external force, and then the arc clamping block 508 will transmit the force to the connecting rod 507, and then the connecting rod 507 will transmit the force to the connecting block 506, and the connecting block 506 will drive the slider 505 to slide inside the slide groove 502, and at the same time, the sliding of the slider 505 will cause the first spring 504 to produce elastic deformation. At this time, the telescopic rod 503 can limit the first spring 504, and then put the lower mold assembly 8 into the inner side of the two arc clamping blocks 508, and at the same time make the external force disappear. At this time, due to the elastic recovery effect of the two first springs 504, the arc clamping block 508 is driven to fix and clamp the lower mold assembly 8.

[0031] The arc clamping block 508 is squeezed to one side by an external force, and then the arc clamping block 508 will transmit the force to the connecting rod 507, and then the connecting rod 507 will transmit the force to the connecting block 506, and the connecting block 506 will drive the slider 505 to slide inside the slide groove 502, and at the same time, the sliding of the slider 505 will cause the first spring 504 to produce elastic deformation. At this time, the telescopic rod 503 can limit the first spring 504, and then put the lower mold assembly 8 into the inner side of the two arc clamping blocks 508, and at the same time, the external force disappears. At this time, due to the elastic recovery effect of the two first springs 504, the arc clamping block 508 is driven to the lower mold assembly 8 For fixed clamping, compared with traditional devices, this device, on the one hand, uses a clever mechanical conduction design, with the help of the arc-shaped clamping block 508, the connecting rod 507, and the connecting block 506 components to transmit the force in sequence, so as to realize the sliding of the slider 505 and the elastic deformation of the first spring 504, so that replacement is convenient; on the other hand, the limiting effect of the telescopic rod 503 ensures the controllability of the elastic deformation and avoids malfunction caused by excessive deformation. Finally, the elastic force of the first spring 504 is used to restore the lower mold assembly 8, which is not only stable and reliable, but also convenient and fast, which greatly improves the replacement efficiency, reduces equipment downtime, and improves the overall production efficiency.

[0032] Among them, the lower die assembly 8 includes a lower die 801 clamped inside two arc-shaped clamping blocks 508. A labyrinth bump 802 is fixedly installed on the top of the lower die 801. An airbag 509 is fixedly installed inside the arc-shaped clamping block 508, and the airbag 509 covers the inner wall of the arc-shaped clamping block 508.

[0033] When the staff performs stamping, the labyrinth valve vane processed by the milling cutter unit is clamped and fitted with the labyrinth bump 802. At the same time, since the height of the two arc-shaped clamping blocks 508 is higher than that of the lower die 801, the airbag 509 inside the arc-shaped clamping block 508 is also higher than the lower die 801. Thus, the airbag 509 can also have a certain stable clamping force on the labyrinth valve vane clamped with the labyrinth bump 802, so as to prevent the labyrinth valve vane from being driven upward when the deburring component 7 scrapes the inner burrs of the labyrinth valve vane upward. At the same time, due to the clamping and fitting, the stability during stamping can be effectively increased.

[0034] By clamping and fitting the labyrinth valve vane processed by the milling cutter unit with the labyrinth bump 802, compared with the traditional device, first of all, the labyrinth valve vane processed by the milling cutter unit is accurately clamped and fitted with the labyrinth bump 802, ensuring the alignment accuracy of processing from the source. Secondly, by cleverly using the height difference of the components, with the design that the arc-shaped clamping block 508 and the airbag 509 inside it are higher than the lower die 801, the airbag 509 exerts a stable clamping force on the valve vane, effectively preventing the valve vane from shifting during the deburring operation of the deburring component 7, ensuring the coherence and accuracy of the processing process. Moreover, the clamping and fitting and the clamping cooperate with each other, greatly enhancing the stability during stamping, reducing the defective rate, and improving the overall production quality and efficiency.

[0035] Among them, both ends of the fixed rod 704 penetrate through the inside of the disc 703, and there are two groups of four fixed rods 704 arranged in a pairwise corresponding manner.

[0036] With two groups of four fixed rods 704 arranged in a pairwise corresponding manner, when the disc 703 is pushed upward by the ejector rod 713, it can be prevented from getting stuck and unable to be pushed due to uneven force.

[0037] Among them, a second spring 706 is fixedly connected between the two extension bumps 705 and is movably sleeved on the outer surface of the scraper 707. The buffer pad 701 is rectangular in shape, and the radius of the buffer pad 701 is greater than the radius of the disc 703.

[0038] With the radius of the buffer pad 701 greater than the radius of the disc 703, when the disc 703 falls back driven by the elastic recovery of the second spring 706, it can be buffered by the buffer pad 701 to avoid excessive vibration and damage to the disc 703.

[0039] Among them, the fixed support frame 6 is in a C-shaped form, and the fixed support frame 6 is located between the transmission block 712 and the second bearing plate 3.

[0040] Due to the C-shaped form of the fixed support frame 6, the supporting force of the buffer pad 701 can be effectively increased, and to a certain extent, part of the force when the disc 703 falls back can be received, thereby assisting the buffer pad 701 in buffering.

[0041] Among them, the extension bump 705 is in an annular form, and one end of the scraping knife 707 extends inside the extension bump 705 and the other end extends to the inside of another extension bump 705.

[0042] Due to the two extension bumps 705 being in an annular form and the other end of the scraping knife 707 extending to the inside of another extension bump 705, the running track of the scraping knife 707 can be limited, always closely attached to the inner wall of the communication groove 708, so that the burrs on the inner side of the punched labyrinth valve sheet can be better removed, avoiding incomplete burr removal caused by displacement of the position.

[0043] Among them, a base 9 is fixedly installed at the bottom of the first bearing plate 1, and the base 9 is fixedly installed around the bottom of the first bearing plate 1.

[0044] Due to the base 9 being fixedly installed around the bottom of the first bearing plate 1, the stability of the entire device can be effectively increased, avoiding being easily affected by external physical factors.

[0045] Working principle and usage process:

[0046] When the staff places the labyrinth valve sheet processed by the milling cutter unit above the lower die assembly 8, then starts the cylinder 709 through an external controller, and then the cylinder 709 will drive the output end to drive the punching upper die 710 downward. Then, since the size of the end of the punching upper die 710 is the same as the size of the communication groove 708 opened, and the communication grooves 708 opened in the lower die assembly 8, the clamping assembly 5 and the second bearing plate 3 are interconnected, the center of the labyrinth valve sheet can be punched. When the distance sensor reaches the set punching completion distance, the punching stops. Then, the punching upper die 710 rises, and will drive the transmission block 712 to move upward through the transmission rod 711. Then, the transmission block 712 will drive the ejector rod 713 to pass through the first communication groove 702 and push the disc 703 upward. Then, the disc 703 drives the extension bump 705 and the scraping knife 707 to pass through the communication groove 708 upward. Then, while continuing to move upward, the multiple scraping knives 707 are attached to the inner side of the punched labyrinth valve sheet, scraping off the burrs, and at the same time, the punched waste will also be taken out together, facilitating recycling. Among them, the first communication groove 702 opened in the buffer pad 701 and the fixed support frame 6 are interconnected.

[0047] When it is necessary to replace different lower die components 8, the arc-shaped clamping block 508 is extruded to one side by an external force. Then, the arc-shaped clamping block 508 will conduct the acting force to the connecting rod 507. After that, the connecting rod 507 will conduct the force to the connecting block 506, and the connecting block 506 will drive the slider 505 to slide inside the chute 502. At the same time, the sliding of the slider 505 will cause the first spring 504 to undergo elastic deformation. At this time, the telescopic rod 503 can limit the first spring 504. Then, the lower die component 8 is placed inside the two arc-shaped clamping blocks 508, and at the same time, the external force disappears. At this time, due to the elastic recovery of the two first springs 504, the arc-shaped clamping blocks 508 are driven to fixedly clamp the lower die component 8.

[0048] When the staff performs stamping, the maze valve vane processed by the milling cutter unit is clamped and fitted with the maze convex block 802. At the same time, since the heights of the two arc-shaped clamping blocks 508 are higher than those of the lower die 801, the airbag 509 inside the arc-shaped clamping block 508 is also higher than the lower die 801. Thus, the airbag 509 can also have a certain stable clamping force on the maze valve vane clamped with the maze convex block 802, so as to prevent the maze valve vane from being driven upward when the deburring component 7 scrapes the inner burrs of the maze valve vane upward during stamping. At the same time, due to the clamping and fitting, the stability during stamping can be effectively increased.
