Description

Technical Field

[0001] The present invention relates to the technical field of rubber-lined pipe processing, and in particular to a post-treatment device for casting rubber-lined pipes. Background Art

[0002] A rubber-lined pipe refers to a pipe system with a rubber material lined inside, which is suitable for transporting corrosive or abrasive fluid media. It varies according to different application scenarios and installation requirements. Common rubber-lined pipes include straight pipes, arc pipes, and tee pipes, etc. Rubber-lined pipes are cast using the sand casting process. The post-casting treatment process usually includes demolding, shakeout, cleaning, machining, etc. Among them, shakeout refers to removing the sand mold material inside and outside the pipe, which can be completed by manual knocking, vibrating table vibration, or an automatic shakeout machine.

[0003] Currently, during the post-treatment of arc-shaped rubber-lined pipe casting, a shakeout machine is mainly used for shakeout treatment. The working principle of the shakeout machine is to separate the mold sand and the casting in the mold by using vibration and impact. When in use, the rubber-lined pipe to be treated is placed on the shakeout machine, and strong vibration is generated on the workbench surface, thereby driving the rubber-lined pipe casting to vibrate at a high frequency. The attachments such as mold sand and core sand on the surface of the rubber-lined pipe casting gradually become loose and fall off, so as to achieve the purpose of cleaning. However, during the process of directly placing the rubber-lined pipe casting on the shakeout machine for shakeout, it is inevitable that there will be collisions and abrasions between multiple rubber-lined pipe castings and between the rubber-lined pipe casting and the shakeout machine, resulting in a decrease in the quality of the finished product. Moreover, through the vibration of a single shakeout machine, it is difficult to fully shake out the sand on the inner wall of the arc-shaped rubber-lined pipe casting, and the processing accuracy of the arc-shaped rubber-lined pipe casting needs to be improved, 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 abrasion of rubber-lined pipe castings, the present invention provides a post-treatment device for casting rubber-lined pipes. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art, and to propose a post-treatment device for casting rubber-lined pipes.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions: A post-treatment device for casting rubber-lined pipes, comprising a base and a sand-falling mechanism II.

The third clamping component includes a vertical plate seat, and the vertical plate seat is fixedly connected to the rear part of the top wall of the supporting frame. A plurality of electric push rods are distributed up and down on the front side wall of the vertical plate seat, and the front side walls of the output ends of the electric push rods are jointly fixedly connected with a U-shaped limiting member with an opening facing forward. Grooves are symmetrically formed on the upper and lower inner walls of the U-shaped limiting member.

[0013] In the above-mentioned post-treatment equipment for casting rubber-lined pipes, the supporting component includes hydraulic rods, and a plurality of hydraulic rods are installed on the left part of the bottom wall of the supporting frame along the circumferential direction. The bottom walls of the hydraulic rods are jointly fixedly connected to a supporting round table corresponding to the left adjusting sliding seat. A plurality of lower sand holes and sand guide channels are formed on the top wall of the supporting round table. The sand guide channels are distributed in an inclined shape along the circumferential direction, and the bottom ends of the sand guide channels are connected to the lower sand holes.

[0014] In the above-mentioned post-treatment equipment for casting rubber-lined pipes, an adjusting disk is rotatably connected to the middle of the top wall of the supporting round table, and a second motor is installed inside the supporting round table.

[0017] Compared with the existing technology, the advantages of the present invention are as follows: 1.

The bottom flange of the rubber - lined pipe casting is simultaneously supported and limited by multiple first clamping members. The third clamping member and the first clamping member cooperate to clamp the bottom flange of the rubber - lined pipe casting. Multiple second clamping members can closely fit the side wall of the rubber - lined pipe casting, facilitating the treatment of the arc - shaped rubber - lined pipe casting.

[0018] 2. Through the cooperation of the first sand - falling mechanism and the force - receiving assembly, large - range vibration sand - falling is carried out on the rubber - lined pipe casting. Under the action of the impact force received by the force - receiving member, the attached substances such as core sand on the rubber - lined pipe casting gradually become loose and fall off, performing large - range sand - falling, avoiding direct collision between the rubber - lined pipe casting and the sand - falling collection frame and grid, and thus avoiding wear of the rubber - lined pipe casting.

[0019] 3. Through the cooperation of the grinding and sand - falling assembly and the rubber column, the inner wall of the rubber - lined pipe casting is finely post - treated by the spherical grinding member and the cleaning brush member. The rubber column drives the spherical grinding member and the cleaning brush member into the interior of the rubber - lined pipe casting. The spherical grinding member driven by the hydraulic rod moves up and down to grind and scrape the core sand adhering to the inner wall of the rubber - lined pipe casting. The cleaning brush member driven by the second motor rotates on the inner wall of the rubber - lined pipe casting to thoroughly clean the residual sand grains and dust impurities on the inner wall of the rubber - lined pipe casting. Through the cooperation of the spherical grinding member and the cleaning brush member, the treatment precision of the rubber - lined pipe casting is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figure 1 , a post-treatment device for rubber-lined pipe castings, including a base 1 and a second sand-falling mechanism 5. A first sand-falling mechanism 2 for performing large-scale sand-falling treatment on rubber-lined pipe castings and a force-bearing component 3 are provided on the base 1. A position-limiting mechanism 4 for limiting the rubber-lined pipe castings and a second sand-falling mechanism 5 for further performing sand-falling treatment on the inner wall of the rubber-lined pipe castings are provided on the force-bearing component 3.

[0033] Flange plates are provided at both the top and bottom of the rubber-lined pipe castings. The rubber-lined pipe castings are limited and clamped through the position-limiting mechanism 4, and two rubber-lined pipe castings are processed simultaneously; through the cooperation of the first sand-falling mechanism 2 and the force-bearing component 3, large-scale vibration sand-falling is performed on the rubber-lined pipe castings, and through the second sand-falling mechanism 5, comprehensive sand-falling and cleaning are performed on the inner wall of the rubber-lined pipe castings, improving the refinement degree of the post-treatment of the rubber-lined pipe castings.

[0034] Refer to Figure 2, the sand falling mechanism 2 includes a sand falling and collecting frame 21. The top wall of the base 1 is connected to the sand falling and collecting frame 21 through a plurality of symmetrically arranged springs on the left and right. A collecting groove is provided inside the sand falling and collecting frame 21. The middle of the top wall of the sand falling and collecting frame 21 is fixedly connected with a grid 22. Electric motors 23 are installed on the front and rear side walls of the sand falling and collecting frame 21.

[0035] Referring to Figure 1 to Figure 2 , the force receiving component 3 includes an inverted L-shaped support frame 31. The top wall of the base 1 is fixedly connected with inverted L-shaped support frames 31 symmetrically on the left and right with the sand falling and collecting frame 21 as the center. A supporting frame 32 is fixedly connected between the two inverted L-shaped support frames 31. Sand discharging ports are symmetrically provided on the bottom wall of the supporting frame 32; A plurality of force receiving members 33 are evenly fixed on the bottom wall of the supporting frame 32 from left to right. The force receiving member 33 is composed of a cylindrical section connected to the supporting 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 receiving member 33 is higher than the height of the top wall of the grid 22.

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

[0037] Referring to Figure 3 , the clamping component 41 includes an adjusting sliding seat 411. The top wall of the supporting frame 32 is symmetrically and fixedly connected with circular adjusting sliding seats 411 on the left and right. The adjusting sliding seats 411 correspond to the sand discharging ports provided on the bottom wall of the supporting frame 32 one by one. A plurality of sliding rails 412 are provided on the top wall of the adjusting sliding seat 411 along the circumferential direction. An arc-shaped clamping member 413 is slidably connected to the sliding rails 412 through springs (not shown in the figure). The top wall of the clamping member 413 is inclined. A limiting hole 414 is provided on the side wall of the clamping member 413.

[0038] Referring to Figure 3 to Figure 4 , the clamping component 42 includes an adjusting slider 421. The adjusting slider 421 is slidably connected to the sliding rail 412 through an electric slider. A support block 422 and a clamping member 425 are fixedly connected to the outer wall of the adjusting slider 421 close to the clamping member 413. A spherical hinge 423 is rotatably connected to the side of the support block 422 close to the clamping member 413. A clamping member 424 is fixedly connected to the side wall of the spherical hinge 423. The clamping member 424 is connected to the support block 422 through a spring; The clamping member 425 is adapted to the limiting hole 414. The outer walls of the clamping member 424 and the clamping member 425 close to the clamping member 413 are arc-shaped and adapted to the outer wall of the rubber-lined pipe casting.

[0039] Reference Figure 1 As shown in Figure 1 , the third clamping assembly 43 includes a vertical plate base 431. The rear part of the top wall of the supporting frame 32 is fixedly connected to the vertical plate base 431. A plurality of electric push rods 432 are distributed up and down on the front side wall of the vertical plate base 431. The front side walls of the output ends of the electric push rods 432 are jointly fixed with a U-shaped limiting member 433 with an opening facing forward. Grooves are symmetrically formed on the upper and lower inner walls of the U-shaped limiting member 433.

[0040] Vertically place the rubber-lined pipe casting between a plurality of first clamping members 413, and gradually move it downward along the inclined wall of the first clamping member 413. Under the extrusion of the rubber-lined pipe casting, a plurality of first clamping members 413 slide on the first slide rail 412, and the springs connecting the first clamping members 413 and the adjusting slide base 411 are stretched accordingly. Through the elastic force of the springs, the bottom flange of the rubber-lined pipe casting is synchronously and preliminarily supported and limited by a plurality of first clamping members 413.

[0041] Subsequently, driven by the electric sliders, a plurality of adjusting sliders 421 slide closer to each other on the first slide rail 412 at the same time. The adjusting sliders 421 drive the third clamping member 425 to move into the limiting hole 414 and make the third clamping member 425 closely adhere to the upper end of the bottom flange of the rubber-lined pipe casting. At the same time, the adjusting sliders 421 limit the position of the first clamping member 413. The third clamping member 425 and the first clamping member 413 cooperate to circumferentially clamp the bottom flange of the rubber-lined pipe casting; at the same time, the adjusting sliders 421 and the support blocks 422 drive the spherical hinge 423 and the second clamping member 424 to move closer to the side wall of the rubber-lined pipe casting. The spherical hinge 423 rotates adaptively, and the springs connecting the spherical hinge 423 and the support blocks 422 expand and contract adaptively, so that a plurality of second clamping members 424 can closely fit the side wall of the rubber-lined pipe casting, facilitating the adaptive clamping of the arc-shaped rubber-lined pipe casting.

[0042] Place two arc-shaped rubber-lined pipe castings symmetrically left and right on the stress member 33. After the bottom parts of the left and right pipe castings are clamped by the first clamping assembly 41 and the second clamping assembly 42, the tops are in a state of being in contact with each other. The electric push rod 432 drives the U-shaped limiting member 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 member 433. The grooves on the U-shaped limiting member 433 simultaneously limit the top positions of the two rubber-lined pipe castings, so as to process the two rubber-lined pipe castings simultaneously later, which is beneficial to improving the processing efficiency of the equipment.

[0043] The first motor 23 is a vibration motor, and the exciting force generated by it enables the sand falling and collecting frame 21 to operate in a state of high frequency and low amplitude. The spring connected between the sand falling and collecting frame 21 and the base 1 undergoes adaptive expansion and contraction. The sand falling and collecting frame 21 and the grid 22 generate strong vibrations. When the grid 22 vibrates, it can intermittently impact the force-bearing member 33 above. The force-bearing member 33 drives the supporting frame 32 and the two clamped rubber-lined pipe castings to vibrate. Under the action of vibration, the attachments such as core sand on the rubber-lined pipe castings gradually loosen and fall off, facilitating large-scale sand falling. The sand falls through the sand discharge ports on the adjusting slide base 411 and the supporting frame 32 into the interior of the grid 22 for unified collection, avoiding direct collision between the rubber-lined pipe castings and the sand falling and collecting frame 21 and the grid 22, and thus avoiding wear of the rubber-lined pipe castings.

[0044] Referring to Figure 1 and Figure 5 , the second sand falling mechanism 5 includes a supporting component 51 for supporting the refined sand falling operation. The supporting component 51 is arranged on the supporting frame 32. The supporting component 51 includes hydraulic rods 511. A plurality of hydraulic rods 511 are installed on the left part of the bottom wall of the supporting frame 32 along the circumferential direction. The bottom walls of the hydraulic rods 511 are commonly fixedly connected to a supporting round table 512 corresponding to the left adjusting slide base 411. A plurality of sand falling holes 513 and sand guiding channels 514 are formed in the top wall of the supporting round table 512. The sand guiding channels 514 are distributed in an inclined shape along the circumferential direction, and the bottom ends of the sand guiding channels 514 are connected to the sand falling holes 513.

[0045] Referring to Figure 5 , Figure 6 and Figure 9 , a regulating disc 516 is rotatably connected to the middle of the top wall of the supporting round table 512. A second motor 515 is installed inside the supporting round table 512. The bottom wall of the regulating disc 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 regulating disc 516. A round table member 53 is fixedly connected to the top wall of the rubber column 52. A rotation driving component 55 is arranged on the regulating disc 516.

[0046] Referring to Figure 6 to Figure 8 , a grinding and sand falling component 54 for performing refined sand falling on the rubber-lined pipe castings is arranged on the supporting component 51. The grinding and sand falling component 54 includes a plurality of chain members 541 evenly distributed along the circumferential direction. The chain members 541 are connected between the top wall of the regulating disc 516 and the bottom wall of the round table member 53 through alternately distributed fixing blocks and sliding blocks. A plurality of spherical grinding members 542 are evenly rotatably arranged on the chain members 541 connected by the fixing blocks from top to bottom. The sliding blocks can slide along the radial direction between the regulating disc 516 and the round table member 53. A plurality of cleaning brush members 543 are evenly fixed on the chain members 541 connected by the sliding blocks from top to bottom.

[0047] Referring to Figure 9 to Figure 10, the rotation drive assembly 55 includes a first adjusting member 551. The bottom wall of the adjusting disc 516 is rotatably connected to the first adjusting member 551. The first adjusting member 551 is composed of an annular section connected to the adjusting disc 516 and two wedge-shaped members symmetrically distributed along the circumferential direction on the side wall of the annular section. The bottom wall of the adjusting disc 516 is symmetrically provided with a second slide rail 554. A second adjusting member 552 is slidably connected to the second slide rail 554. The second adjusting member 552 is fixedly connected to the bottom wall of the chain condition 541 provided with the cleaning brush member 543. The second adjusting member 552 is composed of a T-shaped member connected to the chain condition 541 provided with the cleaning brush member 543 and a wedge-shaped member fixed to the side of the T-shaped member close to the first adjusting member 551. The bottom wall center of the adjusting disc 516 is symmetrically fixed with a blocking block 553 corresponding to the second slide rail 554. A spring is connected between the T-shaped member of the second adjusting member 552 and the blocking block 553.

[0048] The hydraulic rod 511 drives the support frustum 512, the rubber column 52 and the frustum member 53 to move upward. The frustum member 53 and the rubber column 52 penetrate into the inside of the rubber lining pipe casting. The rubber column 52 is made of a flexible material. While providing support for the sanding and sand removal assembly 54, it can adaptively deform inside the rubber lining pipe casting with the change of the curvature of the rubber lining pipe casting, thereby driving the chain condition 541 to bend adaptively. The rubber column 52 enters from the bottom of the left rubber lining pipe casting, moves to the top of the left rubber lining pipe casting and then passes through the top of the right rubber lining pipe casting, enters the inside of the right rubber lining pipe casting, and finally exits from the bottom of the right rubber lining pipe casting; it should be noted that when the size of the rubber lining pipe casting is relatively long, a second sand removal mechanism 5 can be provided on the right part of the bottom wall of the supporting frame 32 to perform operations from both the left and right sides simultaneously.

[0049] The vertically moving spherical sanding member 542 can sand and scrape the sand cores adhered to the inner wall of the rubber lining pipe casting. The sand removed from the left rubber lining pipe casting slides downward under the guidance of the sand guiding channel 514 and falls through the lower sand hole 513 into the grid 22. The sand removed from the right rubber lining pipe casting falls into the grid 22 through the sand discharge ports on the adjusting slide base 411 and the supporting frame 32.

[0050] The second motor 515 is a motor that can rotate forward and backward. When the second motor 515 drives the first adjusting member 551 to rotate clockwise, the wedge-shaped member of the first adjusting member 551 rotates closer to the wedge-shaped member of the second adjusting member 552. When the wedge-shaped member of the first adjusting member 551 closely adheres to the inclined outer wall of the wedge-shaped member of the second adjusting member 552, the continuously rotating first adjusting member 551 pushes the second adjusting member 552 to slide on the second slide rail 554. The spring connected between the T-shaped member of the second adjusting member 552 and the blocking block 553 is stretched accordingly, and the chain condition 541 and the cleaning brush member 543 on the T-shaped member of the second adjusting member 552 move closer to the inner wall of the rubber lining pipe casting.

[0051] When the wedge of the first adjusting part 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-falling assembly 54 to rotate. When the cleaning brush part 543 rotates on the inner wall of the rubber-lined pipe casting, it fully cleans the sand grains, dust and impurities remaining on the inner wall of the rubber-lined pipe casting after being ground by the spherical grinding part 542.

[0052] When the second motor 515 drives the first adjusting part 551 to rotate counterclockwise, the cleaning brush part 543 moves away from the inner wall of the rubber-lined pipe casting. Through the cooperation of the spherical grinding part 542 and the cleaning brush part 543, the processing precision of the rubber-lined pipe casting is improved.

[0053] Refer to Figure 1 - Figure 10 , the specific operation steps of this post-treatment equipment for rubber-lined pipe casting are as follows: First, vertically place the rubber-lined pipe casting between multiple first clamping parts 413. The electric slider drives the third clamping part 425 and the first clamping part 413 to cooperate to clamp the bottom flange of the rubber-lined pipe casting. Multiple second clamping parts 424 adaptively rotate through the spherical hinge 423 and closely fit the side wall of the rubber-lined pipe casting. The electric push rod 432 drives the U-shaped limiting part 433 to limit the top positions of the two rubber-lined pipe castings.

[0054] The first motor 23 drives the sand-falling collection frame 21 and the grid 22 to vibrate, intermittently hitting the stress part 33. The two clamped rubber-lined pipe castings vibrate, and the attached objects such as core sand on the rubber-lined pipe casting gradually loosen and fall off, performing large-scale sand falling; the rubber column 52 drives the grinding and sand-falling assembly 54 to adaptively bend inside the rubber-lined pipe casting, and the hydraulic rod 511 drives the spherical grinding part 542 to move up and down to grind and scrape the core sand adhered to the inner wall of the rubber-lined pipe casting; the second motor 515 drives the cleaning brush part 543 to rotate on the inner wall of the rubber-lined pipe casting to remove the remaining sand grains, dust and impurities on the inner wall of the rubber-lined pipe casting. The core sand debris falls into the interior of the grid 22 and can be sent out through existing transportation equipment after being uniformly collected.

[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
