Description

Technical Field

[0001] This invention relates to the field of rubber-lined pipe processing technology, and in particular to a post-processing device for rubber-lined pipe casting. Background Technology

[0002] Rubber-lined pipes are pipe systems with an internal rubber lining. They are suitable for transporting corrosive or abrasive fluid media. Depending on the application and installation requirements, they vary. Common types of rubber-lined pipes include straight pipes, curved pipes, and tee pipes. Rubber-lined pipes are cast using sand casting technology. The post-casting process usually includes demolding, sand removal, cleaning, and machining. Sand removal refers to removing the sand material inside and outside the pipe, which can be done by manual hammering, vibration table vibration, or automatic sand removal machine.

[0003] Currently, the main post-processing method for casting curved rubber-lined pipes is the use of a sand-removing machine. The working principle of a sand-removing machine is to use vibration and impact to separate the molding sand from the casting. During operation, the rubber-lined pipe to be processed is placed on the sand-removing machine, and the strong vibration generated by the worktable causes the rubber-lined pipe casting to vibrate at high frequency. This gradually loosens and removes the molding sand and core sand adhering to the surface of the casting, achieving the cleaning purpose. However, during the process of directly placing the rubber-lined pipe casting on the sand-removing machine, collisions and wear inevitably occur between multiple castings and between the casting and the machine, leading to a decrease in finished product quality. Furthermore, the vibration of a single sand-removing machine is insufficient to fully remove sand from the inner wall of the curved rubber-lined pipe casting, requiring improved processing precision and increasing the difficulty of subsequent processing.

[0004] Therefore, in order to improve the processing accuracy of arc-shaped rubber-lined pipe castings and reduce the wear of rubber-lined pipe castings, this invention provides a post-processing device for rubber-lined pipe casting. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a post-processing device for casting rubber-lined pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A post-processing device for casting rubber-lined pipes includes a base and a second sand removal mechanism. The base is equipped with a first sand removal mechanism and a force-bearing component for large-scale sand removal processing of the rubber-lined pipe castings. The first sand removal mechanism includes a sand collection frame. The top wall of the base is connected to the sand collection frame by multiple springs arranged symmetrically on the left and right sides. The sand collection frame has a collection groove inside. A grid is fixedly connected to the middle of the top wall of the sand collection frame. A motor is installed on the front and rear side walls of the sand collection frame.

[0007] The force-bearing component includes an inverted L-shaped support frame, and the top wall of the base is symmetrically and fixedly connected with an inverted L-shaped support frame on the left and right sides with the sand collection frame as the center. A support frame is fixedly connected between the two inverted L-shaped support frames, and the bottom wall of the support frame is symmetrically provided with sand discharge ports on the left and right sides. The force-bearing component is provided with a limiting mechanism for limiting the rubber-lined pipe casting and a second sand removal mechanism for further sand removal treatment of the inner wall of the rubber-lined pipe casting. The second sand removal mechanism includes a support component for supporting the fine sand removal operation. The support frame is provided with the support component, and the support component is provided with a grinding and sand removal component for fine sand removal of the rubber-lined pipe casting.

[0008] In the above-mentioned post-processing equipment for casting rubber-lined pipes, multiple force-bearing components are evenly fixed on the bottom wall of the support frame from left to right. Each force-bearing component consists of a cylindrical section connected to the support frame and a disc section whose bottom wall is fixed to the cylindrical section. The bottom wall height of the disc section of the force-bearing component is higher than the top wall height of the grid.

[0009] In the above-mentioned post-processing equipment for casting rubber-lined pipes, the limiting mechanism includes a clamping component one for facilitating the installation of the bottom of the rubber-lined pipe casting, a clamping component two for limiting the bottom of the rubber-lined pipe casting, and a clamping component three for limiting the top of the rubber-lined pipe casting. The support frame is provided with clamping component one and clamping component three, and clamping component two is provided on clamping component one.

[0010] In the above-mentioned post-processing equipment for casting rubber-lined pipes, the clamping assembly includes an adjusting slide, and the top wall of the support frame is symmetrically and fixedly connected with annular adjusting slides. The adjusting slides correspond one-to-one with the sand discharge ports opened on the bottom wall of the support frame. The top wall of the adjusting slide is provided with multiple slide rails along the circumferential direction. The slide rails are slidably connected with arc-shaped clamping parts by springs. The top wall of the clamping parts is inclined, and the side wall of the clamping parts is provided with limit holes.

[0011] In the above-mentioned post-processing equipment for casting rubber-lined pipes, the clamping assembly two includes an adjusting slider, and the adjusting slider is slidably connected to the slide rail one via an electric slider. The outer wall of the adjusting slider near the clamping component one is fixedly connected to a support block and a clamping component three. The support block is rotatably connected to a spherical hinge on the side near the clamping component one. The side wall of the spherical hinge is fixedly connected to the clamping component two, and the clamping component two is connected to the support block via a spring.

[0012] In the above-mentioned post-processing equipment for rubber-lined pipe casting, clamping component three is adapted to the limiting hole. The outer wall of clamping component two and clamping component three near clamping component one is arc-shaped and adapted to the outer wall of the rubber-lined pipe casting. The clamping component three includes a vertical plate seat, and the vertical plate seat is fixedly connected to the rear part of the top wall of the support frame. Multiple electric push rods are distributed vertically on the front side wall of the vertical plate seat, and the front side wall of the output end of the electric push rod is fixed with a U-shaped limiting component with an opening facing forward. The upper and lower inner walls of the U-shaped limiting component are symmetrically provided with grooves.

[0013] In the above-mentioned post-processing equipment for casting rubber-lined pipes, the support assembly includes hydraulic rods, and multiple hydraulic rods are installed on the left side of the bottom wall of the support frame along the circumferential direction. The bottom walls of the hydraulic rods are all fixedly connected to a support truncated cone corresponding to the left-side adjusting slide. The top wall of the support truncated cone is provided with multiple sand-draining holes and sand-guiding channels. The sand-guiding channels are distributed in an inclined manner along the circumferential direction, and the bottom end of the sand-guiding channels is connected to the sand-draining holes.

[0014] In the above-mentioned post-processing equipment for casting rubber-lined pipes, an adjusting plate is rotatably connected to the middle of the top wall of the supporting frustum, and a second motor is installed inside the supporting frustum. The bottom wall of the adjusting plate is connected to the top wall of the output end of the second motor, and a rubber column is fixedly connected to the middle of the top wall of the adjusting plate. A frustum component is fixedly connected to the top wall of the rubber column, and a rotary drive assembly is provided on the adjusting plate.

[0015] In the above-mentioned post-processing equipment for casting rubber-lined pipes, the grinding and sand removal assembly includes multiple chain conditions evenly distributed along the circumferential direction. The top wall of the adjusting disc and the bottom wall of the frustum are connected by the chain conditions through staggered fixed blocks and sliding blocks. Multiple spherical grinding parts are evenly rotated from top to bottom on the chain conditions connected by the fixed blocks. The sliding blocks can slide radially along the adjusting disc and the frustum. Multiple cleaning brushes are evenly fixed from top to bottom on the chain conditions connected by the sliding blocks.

[0016] In the above-mentioned post-processing equipment for casting rubber-lined pipes, the rotary drive assembly includes an adjusting component one, which is rotatably connected to the bottom wall of the adjusting disc. The adjusting component one consists of an annular segment connected to the adjusting disc and two wedge-shaped components that are centrally symmetrically distributed along the circumferential direction on the side wall of the annular segment. The bottom wall of the adjusting disc is symmetrically provided with a slide rail two, on which the adjusting component two is slidably connected. The adjusting component two is fixedly connected to the bottom wall of the chain condition where cleaning brushes are provided. The adjusting component two consists of a T-shaped component connected to the chain condition where cleaning brushes are provided and a wedge-shaped component fixed on the side of the T-shaped component close to the adjusting component one. The bottom wall of the adjusting disc is centrally symmetrically fixed with a blocking block corresponding to the slide rail two, and the T-shaped component and the blocking block of the adjusting component two are connected by a spring.

[0017] Compared with existing technologies, the advantages of this invention are: 1. By using clamping components one, two, and three in combination, two arc-shaped rubber-lined pipe castings are clamped and limited, which helps to improve the processing efficiency of the equipment. The bottom flange of the rubber-lined pipe casting is supported and limited by multiple clamping components one. Clamping component three works in conjunction with clamping component one to clamp the bottom flange of the rubber-lined pipe casting. Multiple clamping components two can fit tightly against the side wall of the rubber-lined pipe casting, which is convenient for processing the arc-shaped rubber-lined pipe casting. The groove on the U-shaped limiting component simultaneously restricts the top position of the two rubber-lined pipe castings, so that the two rubber-lined pipe castings can be processed simultaneously in the future.

[0018] 2. Through the cooperation of the sand-falling mechanism and the force-bearing components, the rubber-lined pipe casting is subjected to large-scale vibration and sand-falling. Under the impact force of the force-bearing components, the core sand and other attached materials of the rubber-lined pipe casting gradually loosen and fall off, resulting in large-scale sand-falling. This avoids direct collision between the rubber-lined pipe casting and the sand-falling collection frame and grid, thereby preventing wear on the rubber-lined pipe casting.

[0019] 3. By combining the sand-removing assembly and the rubber column, the inner wall of the rubber-lined pipe casting is finely post-treated using spherical grinding parts and cleaning brushes. The rubber column drives the spherical grinding parts and cleaning brushes into the interior of the rubber-lined pipe casting. The hydraulic rod drives the up-and-down moving spherical grinding parts to grind and scrape off the sand core adhering to the inner wall of the rubber-lined pipe casting. The cleaning brushes driven by the motor rotate on the inner wall of the rubber-lined pipe casting to thoroughly clean the residual sand particles and dust impurities on the inner wall of the rubber-lined pipe casting. The combination of spherical grinding parts and cleaning brushes improves the processing accuracy of the rubber-lined pipe casting. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1 A post-processing device for casting rubber-lined pipes includes a base 1 and a second sand removal mechanism 5. The base 1 is provided with a first sand removal mechanism 2 for large-scale sand removal processing of the rubber-lined pipe casting and a force-bearing component 3. The force-bearing component 3 is provided with a limiting mechanism 4 for limiting the rubber-lined pipe casting and a second sand removal mechanism 5 for further sand removal processing of the inner wall of the rubber-lined pipe casting.

[0033] Flanges are provided at the top and bottom of the rubber-lined pipe casting. The limiting mechanism 4 limits and clamps the rubber-lined pipe casting, and two rubber-lined pipe castings are processed simultaneously. The sand removal mechanism 2 and the force-bearing component 3 work together to vibrate and remove sand from the rubber-lined pipe casting over a wide range. The sand removal mechanism 5 performs comprehensive sand removal and cleaning on the inner wall of the rubber-lined pipe casting, improving the precision of the post-processing of the rubber-lined pipe casting.

[0034] Reference Figure 2The sand removal mechanism 2 includes a sand collection frame 21. The top wall of the base 1 is connected to the sand collection frame 21 by multiple springs arranged symmetrically on the left and right. The sand collection frame 21 has a collection groove inside. A grid 22 is fixedly connected to the middle of the top wall of the sand collection frame 21. Motors 23 are installed on the front and rear side walls of the sand collection frame 21.

[0035] Reference Figures 1 to 2 The force-bearing component 3 includes an inverted L-shaped support frame 31. The top wall of the base 1 is symmetrically connected with the inverted L-shaped support frame 31 around the sand collection frame 21. A support frame 32 is fixedly connected between the two inverted L-shaped support frames 31. The bottom wall of the support frame 32 is symmetrically provided with sand discharge ports. Multiple force-bearing components 33 are evenly fixed from left to right on the bottom wall of the support frame 32. The force-bearing component 33 consists of a cylindrical section connected to the support frame 32 and a disc section fixed to the bottom wall of the cylindrical section. The height of the bottom wall of the disc section of the force-bearing component 33 is higher than the height of the top wall of the grid 22.

[0036] Reference Figure 1 and Figure 3 The limiting mechanism 4 includes a clamping component 1 41 for facilitating the installation of the bottom of the rubber-lined pipe casting, a clamping component 2 42 for limiting the bottom of the rubber-lined pipe casting, and a clamping component 3 43 for limiting the top of the rubber-lined pipe casting. The supporting frame 32 is provided with the clamping component 1 41 and the clamping component 3 43, and the clamping component 2 42 is provided on the clamping component 1 41.

[0037] Reference Figure 3 The clamping assembly 41 includes an adjusting slide 411. The top wall of the support frame 32 is symmetrically and fixedly connected with the annular adjusting slide 411. The adjusting slide 411 corresponds one-to-one with the sand discharge port opened on the bottom wall of the support frame 32. The top wall of the adjusting slide 411 is provided with multiple slide rails 412 along the circumferential direction. The slide rails 412 are slidably connected with arc-shaped clamping members 413 by springs (not shown in the figure). The top wall of the clamping member 413 is inclined, and the side wall of the clamping member 413 is provided with limit holes 414.

[0038] Reference Figures 3 to 4 The clamping assembly 2 42 includes an adjusting slider 421. The adjusting slider 421 is slidably connected to the slide rail 1 412 via an electric slider. The adjusting slider 421 is fixedly connected to the outer wall of the side near the clamping component 1 413 by a support block 422 and a clamping component 3 425. The support block 422 is rotatably connected to the side near the clamping component 1 413 by a spherical hinge 423. The side wall of the spherical hinge 423 is fixedly connected to a clamping component 2 424. The clamping component 2 424 and the support block 422 are connected by a spring. The clamping component 3 425 is adapted to the limiting hole 414. The outer wall of the clamping component 2 424 and the clamping component 3 425 near the clamping component 1 413 is arc-shaped to adapt to the outer wall of the rubber-lined pipe casting.

[0039] Reference Figure 1 The clamping assembly 3 43 includes a vertical plate seat 431. The vertical plate seat 431 is fixedly connected to the rear of the top wall of the support frame 32. Multiple electric push rods 432 are distributed on the front side wall of the vertical plate seat 431. The front side wall of the output end of the electric push rods 432 is fixed with a U-shaped limiting member 433 with an opening facing forward. The upper and lower inner walls of the U-shaped limiting member 433 are symmetrically provided with grooves.

[0040] The rubber-lined pipe casting is placed vertically between multiple clamping parts 413 and gradually moves downward along the inclined wall of the clamping parts 413. Under the pressure of the rubber-lined pipe casting, the multiple clamping parts 413 slide on the slide rail 412. The spring connecting the clamping parts 413 and the adjusting slide 411 is stretched accordingly. Through the elastic force of the spring, the bottom flange of the rubber-lined pipe casting is initially supported and limited by the multiple clamping parts 413.

[0041] Subsequently, driven by the electric slider, multiple adjusting sliders 421 simultaneously slide closer to each other on the slide rail 412. The adjusting sliders 421 drive the clamping member 425 to move into the limiting hole 414, and make the clamping member 425 tightly adhere to the upper end of the bottom flange of the rubber-lined pipe casting. At the same time, the adjusting sliders 421 restrict the position of the clamping member 413. The clamping member 425 and the clamping member 413 cooperate to circumferentially clamp the bottom flange of the rubber-lined pipe casting. Simultaneously, the adjusting sliders 421 and the support block 422 drive the spherical hinge 423 and the clamping member 424 to move closer to the side wall of the rubber-lined pipe casting. The spherical hinge 423 rotates adaptively, and the spring connecting the spherical hinge 423 and the support block 422 extends and retracts adaptively, so that the multiple clamping members 424 can tightly adhere to the side wall of the rubber-lined pipe casting, which facilitates adaptive clamping of the arc-shaped rubber-lined pipe casting.

[0042] Two arc-shaped rubber-lined pipe castings are placed symmetrically on the force-bearing component 33. After the bottoms of the two pipe castings are clamped by clamping component 1 41 and clamping component 2 42, their tops are in contact. The electric actuator 432 drives the U-shaped limiting component 433 to move forward, so that the top flange of the rubber-lined pipe casting enters the upper and lower grooves of the U-shaped limiting component 433. The grooves on the U-shaped limiting component 433 simultaneously restrict the top position of the two rubber-lined pipe castings, so that the two rubber-lined pipe castings can be processed simultaneously in the future, which helps to improve the processing efficiency of the equipment.

[0043] Motor 23 is a vibrating motor. The excitation force it generates causes the sand collection frame 21 to operate in a high-frequency, low-amplitude state. The spring connecting the sand collection frame 21 and the base 1 adapts to the expansion and contraction. The sand collection frame 21 and the grid 22 generate strong vibrations. When the grid 22 vibrates, it can intermittently impact the force-bearing component 33 above. The force-bearing component 33 drives the support frame 32 and the two clamped rubber-lined pipe castings to vibrate. Under the action of vibration, the core sand and other attached materials of the rubber-lined pipe castings gradually loosen and fall off, which facilitates large-scale sand removal. The sand falls into the interior of the grid 22 through the adjusting slide 411 and the sand discharge port on the support frame 32 for unified collection, avoiding direct collision between the rubber-lined pipe castings and the sand collection frame 21 and the grid 22, thereby avoiding wear on the rubber-lined pipe castings.

[0044] Reference Figure 1 and Figure 5 The second sand removal mechanism 5 includes a support component 51 for supporting the fine sand removal operation. The support component 51 is provided on the support frame 32. The support component 51 includes hydraulic rods 511. Multiple hydraulic rods 511 are installed on the left side of the bottom wall of the support frame 32 along the circumferential direction. The bottom walls of the hydraulic rods 511 are fixedly connected to a support truncated cone 512 corresponding to the left adjustment slide 411. Multiple sand-dropping holes 513 and sand-guide channels 514 are opened on the top wall of the support truncated cone 512. The sand-guide channels 514 are distributed in an inclined manner along the circumferential direction and the bottom end of the sand-guide channels 514 is connected to the sand-dropping holes 513.

[0045] Reference Figure 5 , Figure 6 and Figure 9 An adjusting disk 516 is rotatably connected to the middle of the top wall of the supporting frustum 512. A second motor 515 is installed inside the supporting frustum 512. The bottom wall of the adjusting disk 516 is connected to the top wall of the output end of the second motor 515. A rubber column 52 is fixedly connected to the middle of the top wall of the adjusting disk 516. A frustum component 53 is fixedly connected to the top wall of the rubber column 52. A rotary drive assembly 55 is provided on the adjusting disk 516.

[0046] Reference Figures 6 to 8 The support assembly 51 is provided with a grinding and sanding assembly 54 for fine sand removal of the rubber-lined pipe casting. The grinding and sanding assembly 54 includes multiple chain conditions 541 evenly distributed along the circumference. The top wall of the adjusting disk 516 and the bottom wall of the frustum 53 are connected by the chain conditions 541 through staggered fixed blocks and sliding blocks. Multiple spherical grinding parts 542 rotate evenly from top to bottom on the chain conditions 541 connected by the fixed blocks. The sliding blocks can slide radially along the adjusting disk 516 and the frustum 53. Multiple cleaning brushes 543 are evenly fixed from top to bottom on the chain conditions 541 connected by the sliding blocks.

[0047] Reference Figures 9 to 10The rotary drive assembly 55 includes an adjusting member 551. The adjusting member 551 is rotatably connected to the bottom wall of the adjusting disk 516. The adjusting member 551 consists of an annular segment connected to the adjusting disk 516 and two wedge-shaped parts that are centrally symmetrically distributed along the circumference of the annular segment sidewall. The bottom wall of the adjusting disk 516 is symmetrically provided with a slide rail 554. The adjusting member 552 is slidably connected to the slide rail 554. The adjusting member 552 is fixedly connected to the bottom wall of the chain condition 541 where the cleaning brush 543 is provided. The adjusting member 552 consists of a T-shaped part connected to the chain condition 541 where the cleaning brush 543 is provided and a wedge-shaped part fixed to the side of the T-shaped part near the adjusting member 551. The bottom wall of the adjusting disk 516 is centrally symmetrically fixed with a blocking block 553 corresponding to the slide rail 554. The T-shaped part of the adjusting member 552 and the blocking block 553 are connected by a spring.

[0048] Hydraulic rod 511 drives the supporting frustum 512, rubber column 52, and frustum component 53 to move upward. The frustum component 53 and rubber column 52 penetrate into the interior of the rubber-lined pipe casting. The rubber column 52 is made of flexible material. While providing support for the grinding and sand removal component 54, it can also adapt to the curvature of the rubber-lined pipe casting by changing its curvature. This causes the chain condition 541 to bend adaptively. The rubber column 52 enters from the bottom of the left rubber-lined pipe casting, moves to the top of the left rubber-lined pipe casting, passes through the top of the right rubber-lined pipe casting, enters the interior of the right rubber-lined pipe casting, and finally exits from the bottom of the right rubber-lined pipe casting. It should be noted that when the rubber-lined pipe casting is long, a second sand removal mechanism 5 can be set on the right side of the bottom wall of the support frame 32 to perform operations from both sides simultaneously.

[0049] The up-and-down moving spherical grinding part 542 can grind and scrape off the sand core adhering to the inner wall of the rubber-lined pipe casting. The scraped sand inside the rubber-lined pipe casting on the left side is guided down by the sand guide channel 514 and falls into the grid 22 through the sand drop hole 513. The scraped sand inside the rubber-lined pipe casting on the right side falls into the grid 22 through the sand discharge port on the adjusting slide 411 and the support frame 32.

[0050] Motor 2 515 is a motor capable of forward and reverse rotation. When motor 2 515 drives adjusting component 1 551 to rotate clockwise, the wedge-shaped component of adjusting component 1 551 rotates closer to the wedge-shaped component of adjusting component 2 552. After the wedge-shaped component of adjusting component 1 551 is in close contact with the inclined outer wall of the wedge-shaped component of adjusting component 2 552, the continuously rotating adjusting component 1 551 pushes adjusting component 2 552 to slide on slide rail 2 554. The spring connecting the T-shaped component of adjusting component 2 552 and the blocking block 553 is stretched accordingly. The chain condition 541 and the cleaning brush component 543 on the T-shaped component of adjusting component 2 552 move closer to the inner wall of the rubber-lined pipe casting.

[0051] When the wedge-shaped part of the adjusting component 551 rotates to the blocking block 553, it pushes the blocking block 553 to drive the adjusting disk 516 to rotate. The rotation of the adjusting disk 516 drives the rubber column 52 and the grinding and sand removal assembly 54 to rotate. When the cleaning brush 543 rotates on the inner wall of the rubber-lined pipe casting, it thoroughly cleans the sand particles and dust impurities remaining on the inner wall of the rubber-lined pipe casting after grinding by the spherical grinding component 542.

[0052] When motor 2 515 drives adjustment component 1 551 to rotate counterclockwise, cleaning brush component 543 moves away from the inner wall of the rubber-lined pipe casting. Through the cooperation of spherical grinding component 542 and cleaning brush component 543, the processing accuracy of the rubber-lined pipe casting is improved.

[0053] Reference Figures 1-10 The specific operating steps of this rubber-lined pipe casting post-processing equipment are as follows: First, the rubber-lined pipe casting is placed vertically between multiple clamping parts 413. The electric slider drives the clamping part 425 to cooperate with the clamping part 413 to clamp the bottom flange of the rubber-lined pipe casting. Multiple clamping parts 424 rotate adaptively through the ball hinge 423 to fit tightly against the side wall of the rubber-lined pipe casting. The electric push rod 432 drives the U-shaped limiting part 433 to restrict the top position of the two rubber-lined pipe castings.

[0054] Motor 1 23 drives the sand collection frame 21 and grid 22 to vibrate, intermittently impacting the force-bearing component 33. The two clamped rubber-lined pipe castings vibrate, and the core sand and other attached materials on the rubber-lined pipe castings gradually loosen and fall off, resulting in large-scale sand removal. The rubber column 52 drives the grinding and sand removal component 54 to bend adaptively inside the rubber-lined pipe casting. The hydraulic rod 511 drives the spherical grinding component 542 to move up and down, grinding and scraping the sand core adhering to the inner wall of the rubber-lined pipe casting. Motor 2 515 drives the cleaning brush component 543 to rotate on the inner wall of the rubber-lined pipe casting, removing the sand particles and dust impurities remaining on the inner wall of the rubber-lined pipe casting.
