Description

Technical Field

[0001] This utility model relates to the technical field of valve processing, and specifically to a surface treatment device for valve castings. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. According to their functions, they can be divided into shut-off valves, check valves, and regulating valves. Valves are control components in fluid transport systems and have functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. They can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media.

[0003] According to Chinese Patent No. CN 222226508, a thermal spraying device for wear-resistant treatment of valve surfaces is disclosed. The device includes a first support rod fixed to the upper surface of a base plate, and a valve processing second operating box equipped with a processing mechanism for thermal spraying the valve. This thermal spraying device for wear-resistant treatment of valve surfaces, through the cooperation of an electric push rod, can drive the machine housing to move, thereby driving the motor to move. The movement of the motor can drive the placement platform to move, thereby moving the valve. Simultaneously, the motor drives the placement platform to rotate, allowing the valve angle to be adjusted. Through the cooperation of a rotating block, the valve can rotate and move on a threaded groove, thereby driving a fixing plate to fix the valve.

[0004] The aforementioned spraying equipment for wear-resistant treatment of valve surfaces integrates spraying by using a first operating box with an internal cooling function and a second operating box with an internal spraying function. Combined with a connecting shaft, threaded blocks, and a fixing plate, it allows for the fixed processing of valves of different specifications. However, in actual use, while this device achieves integrated spraying, it cannot achieve continuous spraying. Before each processing step, the valve must be fitted onto the connecting shaft and secured with the threaded blocks and fixing plate, making the operation cumbersome and affecting processing efficiency. Utility Model Content

[0005] The technical problem this invention aims to solve is to overcome the limitations of existing spraying methods, which, while achieving integration during the spraying process, cannot achieve continuous operation. Each time, the valve needs to be fitted onto the connecting shaft and secured with a threaded block and fixing plate, resulting in cumbersome operation and reduced processing efficiency.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] A surface treatment device for valve castings includes a first treatment box, a second treatment box, and a spraying device. The bottom of the first and second treatment boxes is supported by a support platform. The bottom of the first treatment box is rotatably connected to a drive disk. The drive disk has two symmetrically arranged follower components detachably installed inside. One of the follower components has an elastic pressure block at its top that matches the valve delivery end. The top of the elastic pressure block has a lifting mechanism. The lifting mechanism is connected to a drive mechanism above it. A freely lifting and lowering sealing partition is movably arranged on the side of the first treatment box near the opening.

[0008] The driving mechanism includes a telescopic block, the telescopic end of which is fixedly connected to the top of the elastic pressure block, and the telescopic end of which is also connected to the output end of the lifting structure.

[0009] As a preferred embodiment of the present invention, the driving mechanism further includes a second motor fixedly connected to the top of the first processing box, the output end of the second motor passing through the first processing box and connected to the upper end of the telescopic block.

[0010] As a preferred technical solution of this utility model, the lifting mechanism includes a first telescopic cylinder fixedly connected to the bottom of the first processing box. The output end of the first telescopic cylinder passes through the first processing box and is connected to a lifting plate. One side of the lifting plate is rotatably connected to the outer wall of the telescopic end of the telescopic block. While lifting, the telescopic end of the telescopic block controls the elastic pressure block to move vertically up and down, pressing the valve against the follower.

[0011] As a preferred embodiment of this utility model, a toothed ring is connected to the bottom of the drive disc, a drive wheel is meshed with one side of the toothed ring, a first motor is fixedly connected to the bottom of the drive wheel, and one side of the first motor is fixedly connected to the bottom of the first processing box.

[0012] As a preferred embodiment of the present invention, the spraying device includes a conveying pipe and a spray head. The output end of the conveying pipe passes through the first processing box and extends to the inner wall. The input end of the spray head is connected to the output end of the conveying pipe. The spray head is located on the side close to the elastic pressure block.

[0013] As a preferred embodiment of this utility model, the sealing partition is slidably installed inside the first processing box, and a second telescopic cylinder is connected to the top of the sealing partition. One side of the second telescopic cylinder is fixedly installed on the top of the first processing box.

[0014] As a preferred embodiment of this utility model, the inlet of the second processing box corresponds to the outlet of the first processing box and is sealed between them. The interior of the second processing box is equipped with a cooling device, and the material outlet of the second processing box is rotatably connected to a door.

[0015] As a preferred technical solution of this utility model, the drive disk is provided with slots opposite each other inside, and the two follower members are respectively inserted into the corresponding slots. The follower member is composed of a follower seat and a connecting seat. The top of the follower seat is rotatably connected to the bottom of the connecting seat, and the follower seat is inserted into the slot.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model constructs a highly efficient dual-station alternating operation system by setting a rotatable drive disc and two symmetrically arranged follower components on it, effectively realizing continuous production of valve surface treatment and significantly improving processing efficiency. Specifically, the drive disc is rotated by a first motor through the meshing transmission of a drive wheel and a gear ring, which can switch the two follower components mounted on it between the spraying station and the loading and unloading station. When the valve on one follower component is being sprayed at the spraying station, the operator can simultaneously complete the unloading of the treated valve or the installation of the valve to be treated on the follower component at the other station. This design overlaps the time-consuming clamping auxiliary time with the core spraying operation time, eliminating the equipment waiting idle caused by the single-station sequential operation in the background technology, so that the processing flow can be seamlessly connected, thereby greatly improving the valve processing output per unit time.

[0018] 2. This utility model achieves rapid and reliable positioning and driving of the valve on the follower by integrating a quick clamping unit controlled by a lifting mechanism and a driving mechanism. This simplifies the operation steps and ensures the coating quality. The quick clamping unit mainly consists of a lifting plate driven by a first telescopic cylinder, a telescopic block driven by a second motor, and an elastic pressure block. During clamping, the first telescopic cylinder is activated, pressing down the telescopic end of the telescopic block through the lifting plate, which drives the elastic pressure block to firmly press the valve against the corresponding follower. Subsequently, the second motor starts, driving the telescopic block and the elastic pressure block fixed thereto to rotate, thereby driving the clamped valve and the follower to rotate at a uniform speed. This process does not require manually tightening multiple threaded blocks for fixing as described in the background technology. The automatic clamping and rotation drive of the valve can be completed with one click, making the operation extremely simple. At the same time, the uniform rotation of the valve ensures that the spray head can cover its surface with a full-range and uniform coating, effectively improving the consistency and reliability of the surface treatment quality.

[0028] Example 1

[0029] exist Figures 1-3 This utility model provides a technical solution: a surface treatment device for valve castings, including a first treatment box 1, a second treatment box 2, and a spraying device. The spraying device is used for spraying the valve surface. A support platform 20 for supporting the entire device is installed at the bottom of both the first and second treatment boxes 1. A self-controlled rotating drive disc 5 is rotatably connected to the bottom of the first treatment box 1. Two symmetrically arranged follower components 6 are detachably installed inside the drive disc 5, and these follower components 6 are matched to the valve's conveying end port. One of the follower components 6 is located on top of... The unit is equipped with an elastic pressure block 15 that matches the valve delivery end. The top of the elastic pressure block 15 is equipped with a lifting mechanism. The lifting mechanism controls the elastic pressure block 15 to press the valve against the follower 6. Two symmetrically arranged follower 6 are provided. Compared with the prior art, when spraying, the valve on one of the follower 6 can be pre-installed on the valve on the external follower 6, thereby realizing continuous processing. A drive mechanism is connected above the lifting mechanism. A freely lifting sealing partition 17 is movably provided on the side of the first processing box 1 near the opening. The sealing partition 17 prevents the pigment sprayed inside from leaking out.

[0030] Meanwhile, the drive mechanism includes a telescopic block 13, the telescopic end of which is fixedly connected to the top of the elastic pressure block 15, and the telescopic end of which is also connected to the output end of the lifting structure.

[0031] In actual use, the valve port is fitted onto the follower 6, and the drive disc 5 controls its transfer to the area below the elastic pressure block 15. At this time, the lifting mechanism controls the telescopic block 13 to move downward, thereby causing the elastic pressure block 15 to move downward as well and press against the valve port. The drive mechanism then controls the telescopic block 13 to rotate, thereby causing the elastic pressure block 15 to rotate as well, and simultaneously causing the valve and the follower 6 to rotate together. At this time, the spraying device is turned on to carry out the spraying work, and at the same time, the next valve to be processed is fitted onto the follower 6 outside the sealing partition 17. Compared with the existing continuous processing technology, this method is more efficient.

[0032] In one aspect of this embodiment, specifically, the drive disc 5 has corresponding slots 7 inside, and two follower parts 6 are respectively inserted into the corresponding slots 7. The insertion connection is convenient and facilitates the replacement of follower parts 6 according to the actual valve processing conditions, thereby improving the applicability of processing specifications. At the same time, the follower part 6 consists of a follower seat and a connecting seat. The top of the follower seat is rotatably connected to the bottom of the connecting seat. The follower seat is inserted into the slot 7. Therefore, during assembly, one end of the valve is sleeved on the connecting seat. When the elastic pressure block 15 drives the valve to rotate, it drives the connecting seat to rotate on the follower seat, thereby realizing a uniform spraying operation on the valve surface.

[0033] In one aspect of this embodiment, the drive mechanism further includes a second motor 14 fixedly connected to the top of the first processing box 1, the output end of the second motor 14 passing through the first processing box 1 and connected to the upper end of the telescopic block 13.

[0034] In one aspect of this embodiment, the lifting mechanism specifically includes a first telescopic cylinder 11 fixedly connected to the bottom of the first processing box 1. The output end of the first telescopic cylinder 11 passes through the first processing box 1 and is connected to a lifting plate 12. One side of the lifting plate 12 is rotatably connected to the outer wall of the telescopic end of the telescopic block 13. While lifting, the elastic pressure block 15 is controlled to move vertically up and down by driving the telescopic end of the telescopic block 13, so as to press the valve against the follower 6.

[0035] In one aspect of this embodiment, a gear ring 8 is connected to the bottom of the drive disc 5, and a drive wheel 9 is meshed with one side of the gear ring 8. A first motor 10 is fixedly connected to the bottom of the drive wheel 9, and one side of the first motor 10 is fixedly connected to the bottom of the first processing box 1. The first motor 10 controls the drive wheel 9 to control the gear ring 9 to drive the drive disc 5 to rotate, thereby realizing the feeding and discharging of the valves on both sides of the connecting seat.

[0036] In one aspect of this embodiment, the spraying device includes a delivery pipe 3 and a nozzle 4. The output end of the delivery pipe 3 passes through the first processing box 1 and extends to the inner wall. The input end of the nozzle 4 is connected to the output end of the delivery pipe 3. The nozzle 4 is disposed on the side close to the elastic pressure block 15.

[0037] In one aspect of this embodiment, and specifically described, the sealing partition 17 is slidably installed inside the first processing box 1, and the top of the sealing partition 17 is connected to a second telescopic cylinder 16, one side of the second telescopic cylinder 16 is fixedly installed on the top of the first processing box 1.

[0038] In one aspect of this embodiment, the inlet of the second processing box 2 corresponds to the outlet of the first processing box 1 and is sealed between them. The interior of the second processing box 2 is provided with a cooling device 18. The material handling port of the second processing box 2 is rotatably connected to a door 19. Before taking out or placing a valve, the door 19 is opened, and the valve that has been cooled by the cooling device on the internal connecting seat is taken away, and the next valve to be processed is placed on it.

[0039] The working principle of this utility model is as follows: First, the workpiece is prepared for clamping. The operator places the valve casting to be processed onto the follower 6 connecting seat in the second processing box 2 with its conveying port. At this time, the first motor 10 starts and drives the drive disc 5 to rotate 180 degrees through the meshing transmission of the drive wheel 9 and the gear ring 8, transferring the clamped valve to the spraying station in the first processing box 1. At the same time, the processed valve is transferred to the unloading station in the second processing box 2. When the spraying stage begins, the second telescopic cylinder 16 drives the sealing partition 17 to descend, closing the working area of ​​the first processing box 1. The lifting mechanism starts working: the first telescopic cylinder 11 pushes the lifting plate 12 down, driving the telescopic block 13, which is rotatably connected to the lifting plate 12, to move its telescopic end downward, so that the elastic pressure block 15 fixed at its end firmly presses the valve onto the follower 6. After pressing is completed, the drive mechanism starts, and the second motor 10 starts to rotate. The machine 14 drives the telescopic block 13 to rotate, which in turn drives the valve and the connecting seat of the follower 6 to rotate synchronously and uniformly through the elastic pressure block 15. At the same time as the valve rotates, the spraying device starts, and the paint is transported to the nozzle 4 through the conveying pipe 3 and sprayed evenly on the surface of the rotating valve to ensure that the coating covers no dead corners. During this process, the sealing partition 17 effectively prevents the paint from splashing out and ensures a clean working environment. After the spraying process is completed, the first telescopic cylinder 11 rises, the elastic pressure block 15 releases the pressure on the valve, and the first motor 10 drives the drive disc 5 to rotate 180 degrees again, transferring the sprayed valve into the second processing box 2. At the same time, the valve to be processed is transferred into the spraying station. In the second processing box 2, the cooling device 18 forcibly cools and solidifies the high-temperature coating. Finally, the operator opens the door 19, removes the processed valve from the follower 6 at the station, and clamps the new workpiece to be processed, thus forming a continuous operation cycle.

[0040] The entire operation process achieves efficient and continuous valve surface treatment through the switching of the work position of the drive plate 5, the coordinated pressing and rotation of the lifting mechanism and the drive mechanism, and the partitioning of the dual-box body.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
