Description

Technical Field

[0001] The present application relates to the field of grinding, and in particular to a bottom cover punching die device for a pipe cleaning machine. Background Art

[0002] like Figure 1 As shown, a bottom cover of a pipe cleaning machine includes a cover body 10. Two through holes 11 are opened on the cover body 10. The two through holes 11 are symmetrically arranged on both sides of the cover body 10. The through hole 11 has a first vertical surface 111, a first horizontal surface 112 and a second vertical surface 113 connecting the end of the first vertical surface 111 and the end of the first horizontal surface 112. The second vertical surface 113 is perpendicular to the first vertical surface 111 and the first horizontal surface 112.

[0003] In related art, the bottom cover of a pipe cleaning machine is cast from aluminum alloy. After casting, the first vertical surface 111, the first horizontal surface 112, and the second vertical surface 113 may have burrs or protrusions, which affect the use of the pipe cleaning machine bottom cover. In the prior art, the burrs and protrusions on the first vertical surface 111, the first horizontal surface 112, and the second vertical surface 113 are removed manually using a file or emery cloth.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the removal of burrs and protrusions on the first vertical surface, the first horizontal surface and the second vertical surface is completed manually by grinding with a file or emery cloth, and the grinding quality is difficult to control, and there is still room for improvement. Summary of the Invention

[0005] In order to realize the automatic removal of burrs on the first horizontal surface, the first vertical surface and the second vertical surface, the present application provides a bottom cover die device of a pipe cleaning machine.

[0006] The present application provides a bottom cover punching die device for a pipe dredging machine, which adopts the following technical solution:

[0011] A horizontal punching plate is connected to the support plate by sliding in a horizontal direction;

[0012] a horizontal driving source, disposed on the support plate and having an output end connected to the horizontal punching plate, so as to drive the horizontal punching plate to scrape the first horizontal surface and the second vertical surface;

[0013] Two vertical punching plates, which are two in number and are slidably connected to the support plate in the vertical direction; and

[0014] A vertical driving mechanism, which is arranged on the support plate to drive the vertical punching plate to scrape the first vertical surface and the second vertical surface.

[0015] By adopting the above technical solution, the cover body is placed in the placement groove of the placement plate, and the pressing mechanism presses and fixes the cover body on the placement plate, so as to facilitate the horizontal driving source to drive the horizontal punching plate to insert into the through hole, and the vertical driving mechanism drives the vertical punching plate to insert into the through hole, so as to deburr the first horizontal surface, the first vertical surface and the second vertical surface of the through hole, realizing the automatic removal of burrs on the first horizontal surface, the first vertical surface and the second vertical surface.

[0016] Optionally, the vertical driving mechanism includes a vertical driving source.

[0017] Optionally, a guiding plate is fixed on the support plate, a guiding hole aligned with the through hole is arranged on the guiding plate, and the horizontal punching plate passes through the guiding hole and is slidably connected to the guiding plate.

[0018] By adopting the above technical solution, the horizontal punching plate is slidably connected to the support plate in the horizontal direction.

[0019] Optionally, the pressing mechanism includes:

[0020] A fixing plate, which is arranged on the upper side of the support plate;

[0021] A pressing block, which is arranged between the fixing plate and the placement plate, and through grooves for the horizontal punching plate to pass through are arranged on both sides of the pressing block;

[0022] A pressing driving source, which is arranged on the fixing plate and is fixed relative to the fixing plate, and the output end of the pressing driving source is connected to the pressing block to drive the pressing block to press the cover body tightly on the placement plate.

[0023] By adopting the above technical solution, the output end of the pressing driving source extends out to drive the pressing block to descend and press the cover body tightly on the placement plate, realizing the automatic clamping and fixing of the cover body.

[0024] Optionally, the number of the horizontal punching plates is two, the two horizontal punching plates are respectively arranged on both sides of the placement plate, and the horizontal driving source corresponds to the horizontal punching plate one by one.

[0025] By adopting the above technical solution, compared with deburring the first horizontal surface and the second vertical surface of two through holes in sequence by one horizontal punching plate, using two horizontal punching plates makes the deburring effect of the two through holes consistent, and at the same time improves the service life of the horizontal punching plate.

[0026] Optionally, a base is provided on the lower side of the support plate. The fixed plate is fixed relative to the base. A support column is fixed on the base. A guide column is fixed on the upper side of the support column. The support plate is sleeved on the guide column and is slidably connected to the guide column. A first elastic member is sleeved on the guide column. The first elastic member causes the support plate to have a tendency to move away from the base. A blocking member is provided at the upper end of the guide column;

The first end is fixedly connected to the output end of the horizontal driving source. The second end is connected to the linkage block. The linkage block slides vertically along with the second end.

[0031] By adopting the above technical solution, it is realized that the horizontal driving source can drive the horizontal punching plate to insert into the through hole of the cover body, and can also drive the vertical punching plate to insert into the through hole of the cover body, saving power cost and energy.

[0033] A first pulley, which is rotatably connected to the upper side of the support plate; and

[0034] A second pulley, which is rotatably connected to the lower side of the support plate. The pull rope sequentially bypasses the first pulley and the second pulley from the first end to the second end. The first end is horizontally arranged, and the second end is vertically arranged.

[0035] By adopting the above technical solution, as much of the horizontal pulling force of the horizontal driving source as possible is converted into the pulling force on the linkage block in the vertical direction, and at the same time, the horizontal displacement of the output end of the horizontal driving source is equivalently converted into the vertical displacement of the linkage block.

[0036] Optionally, the vertical driving mechanism further includes a second elastic member. The second elastic member is sleeved on the guide column. The second elastic member causes the linkage block to have a tendency to move away from the support plate.

[0037] By adopting the above technical solution, when the piston rod of the horizontal driving source extends, the second elastic member drives the two vertical punching plates to slide out of the two through holes, preparing for the piston rod of the horizontal driving source to contract and drive the two vertical punching plates to insert into the two through holes again, and assisting in realizing the deburring of the first vertical surface and the second vertical surface of the through hole by punching and scraping twice.

The external thread sleeve is rotationally connected to the linkage block in the circumferential direction, and the external thread sleeve is stationary relative to the linkage block in the axial direction.

[0041] By adopting the above technical solution, by rotating the external thread sleeve, the distance between the linkage block and the adjusting plate can be adjusted through the threaded connection between the external thread sleeve and the adjusting plate, and further the stroke of the vertical punching plate in the vertical direction can be adjusted.

[0042] Optionally, a rotating groove is formed on the lower side of the linkage block, and the upper end of the external thread sleeve is inserted into the rotating groove and rotates in the rotating groove.

[0043] By adopting the above technical solution, the external thread sleeve is rotationally connected to the linkage block in the circumferential direction, and at the same time, the external thread sleeve is stationary relative to the linkage block in the horizontal direction.

[0044] In summary, the present application includes at least one of the following beneficial technical effects:

[0056] The following further elaborates on the present application in conjunction with the attached <J Figure 2-8 for a more detailed description of the present application.

[0057] Embodiment 1 of the present application discloses a bottom cover punching die device for a pipe dredging machine.

[0058] Embodiment l

[0059] Refer to Figure 2 And Figure 3, the die device for the bottom cover of the pipe dredging machine includes a support plate 20, a placement plate 30, a downward pressing mechanism 40, a horizontal punching plate 50, a horizontal driving source 60, a vertical punching plate 70, and a vertical driving mechanism 80.

[0060] The placement plate 30 is fixed to the upper side of the support plate 20. A placement groove 31 is formed on the upper side of the placement plate 30 for placing the cover body 10. When the cover body 10 is placed in the placement groove 31, the two through holes 11 of the cover body 10 face upward. The first vertical surface 111 and the second vertical surface 113 of the through hole 11 are vertically arranged, and the first horizontal surface 112 of the through hole 11 is horizontally arranged.

[0061] The downward pressing mechanism 40 is arranged on the upper side of the support plate 20 to press the cover body 10 onto the placement plate 30. Specifically, the downward pressing mechanism 40 includes a fixing plate 41, a pressing block 42, and a downward pressing driving source 43. A support column 221 is fixed to the lower side of the support plate 20. The lower end of the support column 221 is fixed with a base 22. A column 225 is fixed on the base 22 and extends upward from the base 22. The upper end of the column 225 is higher than the support plate 20. The fixing plate 41 is fixed to the upper end of the column 225, and the fixing plate 41 is located on the upper side of the support plate 20. The pressing block 42 is arranged between the support plate 20 and the fixing plate 41. The pressing block 42 is located on the upper side of the placement plate 30, and the lower side of the pressing block 42 has an arc surface adapted to the cover body 10. The downward pressing driving source 43 can be a cylinder or an oil cylinder. In this embodiment, the downward pressing driving source 43 is taken as an example of a cylinder for introduction. The output end of the downward pressing driving source 43 is the lower end of the piston rod. The output end of the downward pressing driving source 43 is fixed to the upper side of the pressing block 42 to drive the pressing block 42 to press the cover body 10 onto the placement plate 30.

[0062] Refer to Figure 3 And Figure 4 , the horizontal punching plate 50 is slidably connected to the support plate 20 in the horizontal direction. Specifically, a guiding plate 21 is fixed to the support plate 20. The guiding plate 21 is located on one side of the placement plate 30. A guiding hole 211 is formed in the guiding plate 21, and the guiding hole 211 corresponds to the through hole 11 of the cover body 10. The horizontal punching plate 50 is adapted to the guiding hole 211 and the through hole 11 of the cover body 10. The horizontal punching plate 50 passes through the guiding hole 211 and is slidably connected to the guiding plate 21 so that the horizontal punching plate 50 can be inserted into the through hole 11 of the cover body 10 to scrape the first horizontal surface 112 and the second vertical surface 113 to remove burrs and protrusions on the first horizontal surface 112 and the second vertical surface 113.

[0063] The horizontal driving source 60 is a cylinder. The cylinder block of the horizontal driving source 60 is fixed on the support plate 20. The end of the piston rod of the horizontal driving source 60 facing the horizontal punching plate 50 is the output end. The output end of the horizontal driving source 60 is fixedly connected to the horizontal punching plate 50 to drive the horizontal punching plate 50 to insert into the through hole 11 of the cover body 10 to scrape the first horizontal surface 112 and the second vertical surface 113.

[0064] The number of the horizontal punching plates 50 can be one or two. When the number of the horizontal punching plates 50 is one, the number of the horizontal driving source 60 and the guiding plate 21 is also one. Driven by the horizontal driving source 60, the horizontal punching plate 50 sequentially inserts into the two through holes 11 of the cover body 10 to scrape the first horizontal surface 112 and the second vertical surface 113 of the two through holes 11.

[0065] When the number of the horizontal punching plates 50 is two, the number of the horizontal driving source 60 and the guiding plate 21 is also two. The two horizontal punching plates 50 are respectively arranged on both sides of the placing plate 30. Correspondingly, the two horizontal driving sources 60 are respectively arranged on both sides of the placing plate 30, and the two guiding plates 21 are respectively arranged on both sides of the placing plate 30. Driven by the corresponding horizontal driving source 60, the two horizontal punching plates 50 respectively insert into the two through holes 11 of the cover body 10 to scrape the first horizontal surface 112 and the second vertical surface 113 of the two through holes 11.

[0066] Refer to Figure 3 and Figure 5 , the vertical punching plate 70 is slidably connected to the support plate 20 in the vertical direction. Specifically, the number of the vertical punching plates 70 is two, and the two vertical punching plates 70 respectively correspond to the two through holes 11 of the cover body 10 on the placing plate 30. The placing plate 30 is provided with guiding holes 32 corresponding to the vertical punching plates 70 one by one. The guiding holes 32 are communicated with the placing grooves 31. The vertical punching plates 70 are inserted into the guiding holes 32 and are slidably connected to the placing plate 30 in the vertical direction. The vertical punching plates 70 are adapted to the guiding holes 32 and the through holes 11 of the cover body 10 so that the vertical punching plates 70 can insert into the two through holes 11 of the cover body 10 to scrape the first vertical surface 111 and the second vertical surface 113 of the through holes 11 to remove burrs and protrusions on the first vertical surface 111 and the second vertical surface 113.

[0067] The vertical driving mechanism 80 includes a vertical driving source 81. The vertical driving source 81 is a cylinder. The cylinder block of the vertical driving source 81 is fixed on the base 22. The piston rod of the vertical driving source 81 is fixedly connected to the two vertical punching plates 70 to drive the two vertical punching plates 70 to slide in the guiding holes 32 in the vertical direction.

[0068] The implementation principle of Embodiment 1 is as follows: The cover body 10 is placed in the placement groove 31 on the placement plate 30. The two through holes 11 of the cover body 10 face upward. The first vertical surface 111 and the second vertical surface 113 of the through hole 11 are vertically arranged, and the first horizontal surface 112 of the through hole 11 is horizontally arranged. The piston rod of the downward pressure driving source 43 extends to drive the pressing block 42 to press the cover body 10 tightly on the placement plate 30 for fixation. The horizontal driving source 60 drives the horizontal punching plate 50 to insert into the through hole 11 to scrape the first horizontal surface 112 and the second vertical surface 113. After the piston rod of the horizontal driving source 60 contracts, the vertical driving source 81 drives the two vertical punching plates 70 to insert into the through hole 11 to scrape the first vertical surface 111 and the second vertical surface 113, realizing automatic deburring of the first horizontal surface 112, the first vertical surface 111 and the second vertical surface 113 of the through hole 11.

[0069] Embodiment 2

[0070] Refer to Figure 6 With Figure 7 In this embodiment, the difference from Embodiment 1 is that a guiding column 222 is fixed on the upper side of the supporting column 221. The diameter of the guiding column 222 is smaller than that of the supporting column 221. The supporting plate 20 is sleeved on the guiding column 222 and is slidably connected with the guiding column 222 in the vertical direction. A first elastic member 223 is sleeved on the guiding column 222. The first elastic member 223 is a compression spring. The first elastic member 223 is sleeved on the guiding column 222. The first elastic member 223 is located between the supporting plate 20 and the supporting column 221. The first elastic member 223 makes the supporting plate 20 tend to move away from the supporting column 221. A blocking member 224 is fixed at the upper end of the guiding column 222. The blocking member 224 limits the supporting plate 20 so that the supporting plate 20 cannot slide off the guiding column 222.

[0071] The difference between this embodiment and Embodiment 1 is that the vertical driving mechanism 80 includes a linkage block 82, a guiding column 83 and a pulling rope 84. The linkage block 82 is arranged on the lower side of the supporting plate 20. The linkage block 82 is fixedly connected with the lower ends of the two vertical punching plates 70. The guiding column 83 is fixed on the lower side of the supporting plate 20. The linkage block 82 is sleeved on the guiding column 83. The linkage block 82 is slidably connected with the guiding column 83 along the axial direction of the guiding column 83. The number of the pulling ropes 84 is two. Both of the two pulling ropes 84 penetrate through the supporting plate 20. The pulling rope 84 has a first end 841 and a second end 842. The first end 841 is fixedly connected with the output end of the horizontal driving source 60, and the second end 842 is connected with the linkage block 82. The linkage block 82 slides vertically along with the second end 842.

[0072] The cover body 10 is placed in the placement groove 31 on the placement plate 30. Two through holes 11 of the cover body 10 are arranged upward. The first vertical surface 111 and the second vertical surface 113 of the through hole 11 are vertically arranged, and the first horizontal surface 112 of the through hole 11 is horizontally arranged. The piston rod of the downward pressure driving source 43 extends to drive the pressing block 42 to press the cover body 10 tightly on the placement plate 30 for fixation. At this time, the first elastic member 223 is compressed. During the process of the support plate 20 descending, the two vertical punching plates 70 are inserted into the two through holes 11 to punch and scrape the first vertical surface 111 and the second vertical surface 113. Subsequently, the horizontal driving source 60 drives the horizontal punching plate 50 to be inserted into the through hole 11 to punch and scrape the first horizontal surface 112 and the second vertical surface 113, realizing automatic deburring of the first horizontal surface 112, the first vertical surface 111, and the second vertical surface 113 of the through hole 11.

[0073] The vertical driving mechanism 80 further includes a second elastic member 87. The second elastic member 87 is a compression spring. The second elastic member 87 is sleeved on the guiding column 83. The second elastic member 87 is located between the linkage block 82 and the support plate 20. The second elastic member 87 makes the linkage block 82 tend to move away from the support plate 20. When the horizontal driving source 60 drives the horizontal punching plate 50 to be inserted into the through hole 11, the second elastic member 87 drives the linkage block 82 to drive the two vertical punching plates 70 to be withdrawn from the through hole 11. When the piston rod of the horizontal driving source 60 contracts, the two vertical punching plates 70 are driven to be inserted into the two through holes 11 again through the pull rope 84 to punch and scrape the first vertical surface 111 and the second vertical surface 113. The first vertical surface 111 and the second vertical surface 113 are punched and scraped twice within the same time, improving the quality of deburring.

[0074] The vertical driving mechanism 80 further includes a first pulley 85 and a second pulley 86. The first pulley 85 is rotatably connected to the upper side of the support plate 20, and the second pulley 86 is rotatably connected to the lower side of the support plate 20. The pull rope 84 sequentially bypasses the first pulley 85 and the second pulley 86 from the first end 841 to the second end 842. The first end 841 is horizontally arranged, and the second end 842 is vertically arranged, so as to convert as much of the horizontal pulling force of the horizontal driving source 60 as possible into the pulling force on the linkage block 82 in the vertical direction, and at the same time convert the horizontal displacement of the output end of the horizontal driving source 60 into the vertical displacement of the linkage block 82 equivalently.

[0075] Refer to Figure 7 And Figure 8, To facilitate the adjustment of the vertical stroke of the vertical impact plate 70 in the vertical direction, the vertical driving mechanism 80 further includes an adjusting plate 88 and an external thread sleeve 89. Specifically, the adjusting plate 88 is disposed on the lower side of the linkage block 82, and the second ends 842 of the two pulling ropes 84 are fixedly connected to the adjusting plate 88. A guide post 881 is fixedly provided on the upper side of the adjusting plate 88. The guide post 881 is vertically arranged and passes through the linkage block 82 and is slidably connected to the linkage block 82 to guide the adjusting plate 88 to slide relative to the linkage block 82 in the vertical direction. The external thread sleeve 89 passes through the adjusting plate 88, and the external thread sleeve 89 is threadedly connected to the adjusting plate 88. A rotating groove 821 is formed on the lower side of the linkage block 82, and the upper end of the external thread sleeve 89 is inserted into the rotating groove 821. The external thread sleeve 89 rotates circumferentially in the rotating groove 821, and the upper end of the external thread sleeve 89 is always kept in the rotating groove 821 under the action of the second elastic member 87. Rotating the external thread sleeve 89 can adjust the distance between the linkage block 82 and the adjusting plate 88 through the threaded connection between the external thread sleeve 89 and the adjusting plate 88, and further adjust the vertical stroke of the vertical impact plate 70 in the vertical direction.

[0076] To facilitate the rotation of the external thread sleeve 89, a rotating rod 891 is fixedly provided on the outer side wall of the external thread sleeve 89. The rotating rod 891 extends from the external thread sleeve 89 in a direction away from the external thread sleeve 89 to form a labor-saving lever, facilitating the user to rotate the external thread sleeve 89 by holding the rotating rod 891.

[0077] The implementation principle of Embodiment 2 is as follows: The cover body 10 is placed in the placement groove 31 on the placement plate 30. The two through holes 11 of the cover body 10 face upward. The first vertical surface 111 and the second vertical surface 113 of the through hole 11 are vertically arranged, and the first horizontal surface 112 of the through hole 11 is horizontally arranged. The piston rod of the downward pressure driving source 43 extends to drive the pressing block 42 to press the cover body 10 tightly on the placement plate 30 for fixation. At this time, the first elastic member 223 is compressed. During the process of the support plate 20 descending, the two vertical impact plates 70 are inserted into the two through holes 11 to scrape the first vertical surface 111 and the second vertical surface 113. Subsequently, the piston rod of the horizontal driving source 60 extends. The two vertical impact plates 70 first slide out of the two through holes 11 under the drive of the second elastic member 87, and then the horizontal impact plate 50 is inserted into the through hole 11 under the drive of the horizontal driving source 60 to scrape the first horizontal surface 112 and the second vertical surface 113. When the piston rod of the horizontal driving source 60 contracts, the two vertical impact plates 70 are driven to insert into the two through holes 11 again through the pulling ropes 84 to scrape the first vertical surface 111 and the second vertical surface 113 again. Finally, the piston rod of the downward pressure driving source 43 contracts, and the first elastic member 223 drives the support plate 20 to rise, and the cover body 10 is removed from the placement plate 30, realizing the automatic deburring of the first horizontal surface 112, the first vertical surface 11 and the second vertical surface 113 of the through hole 11.

[0078] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
