Description

Technical Field

[0001] The invention belongs to the technical field of fire hydrant processing, and in particular relates to a workpiece processing device for fire hydrant production. Background Art

[0002] Fire hydrants are core components of urban fire protection systems, and their production quality directly impacts the reliability of emergency response. Fire hydrants are typically constructed from high-strength cast iron or ductile iron pipes (wall thickness 8 to 12 mm), requiring precise cutting and threading. However, existing pipe processing equipment suffers from significant technical deficiencies in cutting accuracy, process efficiency, and stability. For example, Chinese patent application CN118875382A proposes a cutting device for fire hydrant pipes. While this patent can achieve the desired cutting performance, it still presents several challenges.

[0003] First of all, although this patent realizes automatic rolling when cutting fire hydrant pipes, in actual use, this patent cannot limit the pipes. During the cutting and rolling process, the pipes being processed can easily detach from the supporting wheels below, thereby affecting the cutting of the pipes.

[0004] Secondly, fire hydrant pipes must reserve flange welding positions and threaded sections according to standards (such as GB 4452), and the cutting position error must be controlled within ±0.2mm. However, this patent lacks the function of adjusting the position of fire hydrant pipes. During the processing, the adjustment of the cutting position is too troublesome, which is not only inefficient but also very easy to cause cutting position errors, affecting the yield rate.

[0005] Finally, fire hydrant pipes need to be processed in a variety of diameters (80-200mm) due to differences in models. Although the above patent can achieve the cutting of fire hydrant pipes with different wall thicknesses, when cutting fire hydrant pipes of different diameters, the position and angle of the supporting wheels below are fixed, which can easily cause the pipes to deviate or be unable to roll when cutting fire hydrant pipes of different diameters, affecting the cutting process. Summary of the Invention

[0006] The purpose of the present invention is to provide a workpiece processing device for fire hydrant production, which can drive the pipe to move left and right to adjust the cutting position before cutting the pipe, and can also drive the pipe to roll during pipe cutting to achieve circular cutting.

[0051] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0052] Please see the attached Figure 1 、 Figures 6 and 7 ,as well as Figures 13 to 16 As shown, this embodiment provides a workpiece processing device for fire hydrant production, comprising:

[0053] The main body 10 has two sets of clamping rods 11 slidably connected to the upper end of the main body 10;

[0054] The regulating assembly 20 includes four sets of brackets 21. The inner cavities of the four sets of brackets 21 are respectively hinged with two sets of traversing wheels 22. The lower end of the main body 10 is provided with a sprocket rod 24 below the brackets 21.

[0055] The tumbling assembly 30 includes two sets of sliding frames 31, which are slidably connected to the front and rear sides of the inner cavity of the bracket 21. The upper ends of the two sets of sliding frames 31 are hinged with longitudinal wheels 32, and the lower end of the main body 10 is provided with a chain 39 below the sliding frames 31;

[0056] The lifting assembly 40 includes a trapezoidal block 45 , which is in contact with and connected to the bottom of the sliding frame 31 ;

[0057] Cutting assembly 50 includes a motor 53 mounted above main body 10, and a sprocket rod 3 54 is fixedly connected to the output shaft of motor 53. The end of sprocket rod 3 54 is engaged with a chain 55, the upper end of chain 55 is engaged with a cutter 56, and the middle outer ring of sprocket rod 3 54 is engaged with a chain 6 57;

[0058] Linkage assembly 60, linkage assembly 60 includes sprocket rod five 63, sprocket rod five 63 is engaged with the rear end of chain four 39, and the front top of multiple sets of sprocket rod one 24 is engaged with chain nine 67;

[0059] Among them, the chain six 57 is used to transmit the braking force of the motor 53, driving the sprocket rod 1 24 and the chain four 39 to roll, thereby driving the traverse wheel 22 and the longitudinal wheel 32 to rotate;

[0060] The trapezoidal block 45 is used to drive the sliding frame 31 to move up and down, and control the steel pipe to be cut to contact one of the traverse wheels 22 and the longitudinal wheels 32.

[0061] It should be noted that the four sets of brackets 21 are symmetrically distributed on the left and right sides of the upper end of the main body 10, and a gap is reserved between the two sets of brackets 21 on each side. The clamping rod 11 is slidably connected in the gap, so that the clamping rod 11 can form a triangular clamping structure with the two sets of brackets 21, thereby improving stability during pipe cutting;

[0062] A sprocket is fixedly connected to the rotating shaft of the cutter 56, and the inner ring of the upper end of the chain 55 is meshed with the outer ring of the sprocket.

[0063] Preferably, in order to ensure that the cutter 56 can be easily maintained and replaced later, the cutter 56 and its rotating shaft can be fixed in a detachable manner, for example, by nuts, bolts, and positioning pins, so that the blade part of the cutter 56 can be removed and replaced separately when the rotating shaft is connected to the chain 55.

[0064] In this embodiment, when the pipe is placed on the bracket 21, the motor 53 drives the sprocket rod 3 54 to rotate, driving the chain 6 57 and the linkage assembly 60. The linkage assembly 60 drives the chain 9 67 and the sprocket rod 1 24 to rotate. The sprocket rod 1 24 then drives the traversing wheel 22 to rotate, moving the pipe left and right to adjust the cutting position. After the position is adjusted, the lifting assembly 40 drives the trapezoidal block 45 to slide, pushing the sliding frame 31 and the longitudinal wheel 32 upward, so that the longitudinal wheel 32 contacts the pipe and pushes it upward, breaking contact with the traversing wheel 22. Simultaneously, the clamping rod 11 descends to contact the upper end of the pipe, securing it. The motor 53 then operates again, and the linkage assembly 60 drives the sprocket rod 5 63 and the chain 4 39 to roll. This, through the rolling assembly 30, drives the longitudinal wheel 32 to rotate, causing the pipe to roll longitudinally. At the same time, the cutting assembly 50 drives the cutter 56 to rotate downward to contact the pipe, and the motor 53 drives the cutter 56 to rotate and cut through the chain 5 55, so that the longitudinal rotation and cutting of the pipe are carried out simultaneously to complete the circular cutting of the pipe.

[0065] Next, please refer to Figures 1 to 4 , two groups of pneumatic rods 12 are fixedly installed at the lower end of the inner cavity of the main body 10, the lower ends of the two groups of clamping rods 11 pass through the main body 10, and the lower ends of the two groups of clamping rods 11 are respectively fixedly connected to the output ends of the two groups of pneumatic rods 12, and the upper ends of the inner cavities of the two groups of clamping rods 11 are movably sleeved with two groups of auxiliary wheels 13, and the upper ends of the outer shells of the two groups of auxiliary wheels 13 are fixedly connected with compression spring sheets 14, and the upper ends of the two groups of compression spring sheets 14 are fixedly connected to the upper ends of the inner cavity of the clamping rods 11;

[0066] A through slot is formed in the middle of the upper end of the main body 10 , and a recovery box 15 is fixedly connected below the through slot.

[0067] It should be noted that the auxiliary wheel 13 is composed of a shell and a hinged rubber wheel inside the shell, and the compression spring 14 is fixedly connected to the upper end of the auxiliary wheel 13 shell to prevent the auxiliary wheel 13 from being separated from the clamping rod 11 and affecting subsequent use;

[0068] The inner cavity at the upper end of the clamping rod 11 is an arc-shaped structure, and the curvature is the same as that of the bracket 21;

[0069] Here, the auxiliary wheels 13 provided at the upper end of the inner cavity of each set of clamping rods 11 are arranged in an arc shape, so that the auxiliary wheels 13 can fit the upper end of the pipe to assist the pipe in rolling during cutting.

[0070] Preferably, in order to ensure that the recovery box 15 can be used normally, it should be filled with cooling liquid, and a drain outlet should be opened on the front of the recovery box 15 (not shown in the figure, and this is a common technical structure in the prior art, so no further details will be given), so that the waste generated by pipe cutting can fall into the recovery box 15 for collection.

[0071] In this embodiment, when securing the pipe, the pneumatic rod 12 contracts, driving the clamping rod 11 downward, allowing the auxiliary wheel 13 to contact the upper end of the pipe. Leveraging the elasticity of the compression spring 14, the auxiliary wheel 13 can conform to the curvature of the upper end of the pipe, improving stability during pipe cutting. Furthermore, a through-slot design at the upper end of the main body 10 allows waste generated during cutting to fall directly into the recovery box 15 below, preventing waste from scattering and affecting the working environment. Cooling liquid within the recovery box 15 also provides preliminary cooling for the waste, reducing the impact of heat generated during cutting on the device.

[0072] Next, please refer to Figures 6 and 7 The regulating assembly 20 also includes two sets of chains 23, both of which are engaged with the rotating shafts of the two sets of traversing wheels 22, and the lower ends of the two sets of chains 23 pass through the bracket 21 and the main body 10, and are engaged with the outer ring of the sprocket rod 24.

[0073] It should be noted that a sprocket structure is provided on the rotating shaft of the traverse wheel 22, and the sprocket structure is meshed with the upper inner ring of the chain 1 23;

[0074] Three sets of sprockets are fixedly connected to the outer ring of the sprocket rod 24, two of which are engaged with the lower ends of the two sets of chains 23, and the remaining set of sprockets is set at the top front end of the sprocket rod 24 and engaged with the inner ring of the chain 9 67.

[0075] In this embodiment, when the sprocket rod 24 is driven to rotate by the chain 9 67, the sprocket rod 24 drives the two sets of chains 23 to rotate, and the chain 23 drives the traverse wheel 22 to roll, thereby realizing the movement and adjustment of the pipeline, which is convenient for adjusting the cutting position.

[0076] Next, please refer to Figures 6 to 9 The tumbling assembly 30 also includes a tension spring 33, which is fixedly connected to the upper end of the inner ring of the sliding frame 31, and the lower end of the tension spring 33 is fixedly connected to the lower end of the inner cavity of the bracket 21. The rotating shaft of the longitudinal wheel 32 extends into the inner cavity of the sliding frame 31, and a second chain 34 is engaged with the rotating shaft of the longitudinal wheel 32. The inner ring of the lower end of the second chain 34 is engaged with a transmission wheel 35. The transmission wheel 35 is rotatably connected to the lower end inner cavity of the sliding frame 31 through a ball bearing, and the end of the transmission wheel 35 away from the longitudinal wheel 32 passes through the sliding frame 31 and is placed on the outer side of the sliding frame 31;

[0077] The tumbling assembly 30 also includes a chain three 36, which is engaged with one end of the transmission wheel 35 extending out of the sliding frame 31. The lower end of the main body 10 is hinged with a sprocket rod 2 37. The inner ring of the end of the chain four 39 close to the longitudinal wheel 32 is engaged with the outer ring of the sprocket rod 2 37. The inner ring of the upper end of the chain three 36 is also engaged with the outer ring of the sprocket rod 2 37. The inner ring of the middle section of the chain three 36 is engaged with the tensioning wheel 38, and the tensioning wheel 38 is installed at the lower end of the main body 10.

[0078] It should be noted that the outer ring of the second sprocket rod 37 is provided with two sets of independent sprocket structures, and the two sets of sprocket structures are respectively meshed with the inner rings of the third chain 36 and the fourth chain 39, so that the power transmitted by the fourth chain 39 can be transmitted to the transmission wheel 35 through the second sprocket rod 37 and the third chain 36, thereby driving the longitudinal wheel 32 to roll and driving the pipe to rotate during cutting;

[0079] The tension spring 33 is a tension spring, which is designed to retract the sliding frame 31 and the longitudinal wheel 32 into the inner cavity of the bracket 21 through the tension spring 33 under normal conditions. Only when the sliding frame 31 is driven upward by the trapezoidal block 45 can the longitudinal wheel 32 contact the pipe to be cut. The trapezoidal block 45 is designed to drive the pipe to be cut to selectively contact the longitudinal wheel 32 or the traverse wheel 22, thereby controlling the pipe to be cut to selectively adjust its position or roll, thereby facilitating the adjustment and cutting operation.

[0080] The sliding frame 31 has an N-shaped structure, and the longer parts on both sides of the sliding frame 31 pass through the main body 10 and the bracket 21, and the lower end thereof is placed on the outer side of the lower end of the main body 10. The two sets of sliding frames 31 are inclined, and the inclination direction is the center of the bracket 21. The purpose is to enable the sliding frame 31 to move along the inclined path toward the center of the bracket 21 when rising, thereby lifting the pipe to be cut and disconnecting it from the traversing wheel 22, so as to avoid the pipe being driven to move by the traversing wheel 22 during the rolling cutting process, thereby affecting the accuracy and integrity of the cutting.

[0081] Preferably, in order to ensure that the chain three 36 is always engaged with the transmission wheel 35 during the up and down movement of the sliding frame 31, the tensioning wheel 38 should be provided with a spring tensioning structure, so that the chain three 36 can always connect the transmission wheel 35 and the sprocket rod two 37 together.

[0082] In this embodiment, when chain 4 39 is driven to rotate by sprocket rod 5 63, chain 4 39 drives sprocket rod 2 37, which in turn drives chain 3 36. Chain 3 36 then drives chain 2 34 via transmission wheel 35. Chain 2 34 ultimately drives longitudinal wheel 32, achieving the tumbling action of the pipe. Furthermore, because the tensioning pulley 38 is engaged with the inner ring of the middle section of chain 3 36, the provision of tensioning pulley 38 ensures the stability and reliability of chain 3 36 during transmission, preventing transmission failure caused by chain slack.

[0083] Please refer again Figure 5 、 Figures 10 to 12 The lifting assembly 40 also includes a hydraulic rod 41, which is fixedly mounted on the middle part of the lower end of the main body 10, and a slide 42 is fixedly connected to the output end of the hydraulic rod 41. Four groups of pull rods 43 are fixedly connected to the side of the slide 42 close to the sliding frame 31. The lower end of the main body 10 is fixedly connected to four groups of protective shells 44 below the four groups of brackets 21. The four groups of pull rods 43 are respectively slidably connected to the four groups of protective shells 44, and the parts of the four groups of pull rods 43 extending into the inner cavity of the protective shell 44 are fixedly connected to the middle part of the trapezoidal block 45.

[0084] It should be noted that a guide bar is provided at the lower end of the inner cavity of the protective shell 44, and the trapezoidal block 45 is slidably connected to the guide bar. The guide bar is intended to limit the range of movement of the trapezoidal block 45 so that the trapezoidal block 45 can only slide at the lower end of the sliding frame 31 and cannot slide to the sides.

[0085] A right-angled trapezoidal structure is provided at the upper end of the trapezoidal block 45, and the bottom end of the slope of the right-angled trapezoidal structure is in contact with the lower end of the sliding frame 31. At the same time, the lower end of the sliding frame 31 and the upper end of the trapezoidal block 45 are both rounded, so that the slope of the upper end of the trapezoidal block 45 can be used to push the sliding frame 31 upward, and the rounding makes the driving upward process smoother.

[0086] In this embodiment, under normal conditions, the pipe to be cut only contacts the upper end of the traversing wheel 22, while the longitudinal wheel 32 is housed within the inner cavity of the bracket 21. Once the pipe position is adjusted and cutting is required, the hydraulic rod 41 pushes the slide 42 and the pull rod 43 to move, driving the trapezoidal block 45. The slope at the upper end of the trapezoidal block 45 then pushes the carriage 31 upward, bringing the longitudinal wheel 32 into contact with the pipe. Continued movement of the hydraulic rod 41 causes the longitudinal wheel 32 to push the pipe upward until it disengages from the traversing wheel 22, preventing the rotating traversing wheel 22 from affecting the accuracy of the pipe cutting during subsequent cutting.

[0087] Please refer again Figures 14 to 16 The cutting assembly 50 also includes a rotating frame 51, which is hinged at the middle of the upper end of the main body 10, and the cutter 56 is installed at the upper end of the rotating frame 51. The upper end of the main body 10 is hinged with an electric push rod 52, and the output end of the electric push rod 52 is hinged at the middle of the upper end of the rotating frame 51. The sprocket rod three 54 is rotatably connected to the upper end of the main body 10 through a ball bearing and a bracket, and the outer ring of the rotating frame 51 is fixedly connected to a protective shell, and the protective shell is only fixedly connected to the rotating frame 51, and is in contact with the outside of the rotating shaft connecting the rotating frame 51 and the main body 10.

[0088] It should be noted that the rotating frame 51 is a T-shaped structure, and the output end of the electric push rod 52 is hinged to the protruding end of the rotating frame 51, so that the rotating frame 51 can be driven to rotate up and down by the extension and contraction of the electric push rod 52;

[0089] A through slot is provided at the upper end of the main body 10 at the position of the chain six 57, and a protective shell is provided on the through slot so that the chain six 57 can pass through the main body 10 through the through slot.

[0090] In this embodiment, under normal conditions, the rotating frame 51 and the cutter 56 are lifted up and do not contact the pipe, so as to avoid the rotating cutter 56 contacting the pipe and affecting the adjustment work when the pipe is adjusted. When cutting the pipe, the motor 53 drives the sprocket rod three 54 to rotate, and drives the cutter 56 to rotate through the chain five 55. At the same time, the electric push rod 52 extends, pushing the rotating frame 51 down, so that the cutter 56 contacts the pipe and cuts.

[0091] Please refer again Figure 10 、 Figure 13 、 Figure 16 The linkage assembly 60 also includes a sprocket rod 4 61, which is hinged at the lower end of the main body 10, and the lower end of the chain 6 57 passes through the main body 10, and the inner ring of the lower end of the chain 6 57 is engaged with the outer ring of the sprocket rod 4 61, and the middle outer ring of the sprocket rod 4 61 is engaged with the chain 7 62, and the inner ring of the other end of the chain 7 62 passes through the protective shell 44 and is engaged with the outer ring of the sprocket rod 5 63, and the outer ring of the sprocket rod 5 63 is engaged with the rear end inner ring of the eight sets of chains 4 39, and the sprocket rod 4 61 is away from the chain The outer ring of one end of chain link 6 57 is engaged with chain link 8 64, and the inner ring of the other end of chain link 8 64 is engaged with linkage wheel 1 65. Linkage wheel 1 65 is rotatably connected to the lower end of the main body 10 via a ball bearing. The lower end of the main body 10 is rotatably connected to linkage wheel 2 66 via a ball bearing. The outer ring of linkage wheel 2 66 is engaged with the outer ring of linkage wheel 1 65, and the outer ring of linkage wheel 2 66 is engaged with the inner ring of chain link 9 67. The inner ring of chain link 9 67 is engaged with the sprocket structure at the outer end of the fourth sprocket rod 1 24.

[0092] The linkage wheel 1 65 and the linkage wheel 2 66 are both composed of bevel gears and transmission sprockets, and the bevel gears of the linkage wheel 1 65 and the linkage wheel 2 66 are meshed with each other, while the outer rings of the transmission sprockets are respectively meshed with the inner rings of the chain 8 64 and the chain 9 67, so that the chain 8 64 and the chain 9 67 can transmit power in the vertical direction through the linkage wheel 1 65 and the linkage wheel 2 66.

[0093] It should be noted that a protective shell is provided at the outer edge of the linkage assembly 60 at the lower end of the main body 10, and the sprocket rod 4 61 is rotatably connected to the inner cavity of the protective shell through a ball bearing.

[0094] In this embodiment, as sprocket rod three 54 rotates, it also drives sprocket rod four 61 via chain six 57. Sprocket rod four 61, in turn, drives sprocket rod five 63 via chain seven 62. Sprocket rod five 63, in turn, drives multiple sets of chain four 39 to rotate synchronously. Simultaneously, sprocket rod four 61 transmits power to linkage wheel one 65 via chain eight 64. Linkage wheel one 65 meshes with the bevel gear of linkage wheel two 66, thereby driving linkage wheel two 66 to rotate. The rotation of linkage wheel two 66 in turn drives chain nine 67, which ultimately drives four sets of sprocket rods one 24 to rotate synchronously. This series of chain transmission and gear meshing designs ensures the coordinated and synchronized operation of all components of the entire device.

[0095] The working principle of the present invention is as follows: after the pipe to be cut is placed on the bracket 21, the motor 53 drives the sprocket rod three 54 and the chain six 57 to rotate, and drives the sprocket rod four 61 to rotate. The sprocket rod four 61 will drive the linkage wheel one 65 and the linkage wheel two 66 to rotate through the chain eight 64, and then drive the chain nine 67 and the sprocket rod one 24 to rotate. The sprocket rod one 24 drives the two sets of chain one 23 to rotate, and the chain one 23 drives the traverse wheel 22 to roll, thereby realizing the movement and adjustment of the pipe. After the cutting position of the pipe is adjusted, the motor 53 stops running. At this time, the hydraulic rod 41 pushes the slide 42 and the pull rod 43 to move, driving the trapezoidal block 45 to move. The slope at the upper end of the trapezoidal block 45 is used to push the sliding frame 31 up, so that the longitudinal wheel 32 contacts the pipe and pushes the pipe up until it is out of contact with the traverse wheel 22. At the same time, the pneumatic rod 12 contracts, driving the clamping rod 11 to descend, so that the auxiliary wheel 13 contacts the upper end of the pipe. The elasticity of the compression spring 14 is used to make the auxiliary wheel 13 fit the curvature of the upper end of the pipe, thereby improving the stability during pipe cutting. Then, the motor 53 starts running again, and the rotating sprocket rod 4 61 drives the sprocket rod 5 63 via the chain 7 62. The sprocket rod 5 63 then drives the multiple sets of chains 4 39 to rotate synchronously. At this time, the chain 4 39 drives the sprocket rod 2 37 to rotate, which in turn drives the chain 3 36 to rotate. The chain 3 36 drives the chain 2 34 via the transmission wheel 35. The chain 2 34 finally drives the longitudinal wheel 32 to rotate, achieving the rolling action of the pipe. The rotating sprocket rod 3 54 drives the cutter 56 to rotate via the chain 5 55. At the same time, the electric push rod 52 extends, pushing the rotating frame 51 downward, allowing the cutter 56 to contact the pipe and cut it. This achieves the simultaneous rolling and cutting of the pipe, completing the circular cutting of the fire hydrant pipe.

It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention.
