Description

Technical Field

[0001] This invention relates to steel pipe processing technology, specifically a cutting machine for processing agricultural machinery mufflers. Background Technology

[0002] As is widely known, the core technology of agricultural machinery mufflers is to change the cross-section of the pipe and reflect and interfere with the sound waves through the side resonant cavity, thereby canceling out part of the sound waves.

[0003] For example, the invention patent with application publication number CN103752944A, application publication date April 30, 2014, entitled "A Hydraulic Automatic Steel Pipe Cutting Machine Saw Blade Clamping and Moving Device", has a saw blade mounted on the output shaft of a first motor via a reversing reducer. The reversing reducer is fixed to the side of a moving block, and the other side of the moving block is mounted on a guide rail on the side of the machine head. A first stop block and a second stop block are mounted on the side of the machine head near the moving block. The upper side of the moving block is connected to the piston rod of a first hydraulic cylinder. The hydraulic system is connected to the first hydraulic cylinder, and the cylinder body of the first hydraulic cylinder is mounted on the upper end face of the machine head. A first clamping device assembly is mounted on the frame and located directly below the saw blade. A second clamping device is connected to the piston rod of the second hydraulic cylinder. The second hydraulic cylinder is fixed to the frame via a base. A limit plate is also mounted on the piston rod of the second hydraulic cylinder, and a sliding ruler is mounted on the limit plate. A stationary ruler corresponding to the sliding ruler is mounted on the frame. This invention enables automation of the saw blade cutting process in steel pipe cutting machines and reduces the impact on the saw blade.

[0004] The shortcoming of the existing technology is that the steel pipe is the core of the production of the muffler. During production, the steel pipe blank needs to be planed and cut to form a regular rough blank, which is convenient for subsequent automated production. Planing is done by moving the steel pipe axially through the machine so that the cutting tool can plan the surface of the steel pipe. The planing and cutting of the steel pipe blank is mostly done by two mechanical devices, which requires re-loading and unloading, thus reducing the efficiency of automated production. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting machine for processing agricultural machinery mufflers, so as to solve the above-mentioned shortcomings in the prior art.

[0012] Wherein, the radial slide plate moves away from the planing unit along the axial guide rail to drive the steel pipe axis to move for planing;

[0013] The radial slide plate moves close to the planing unit along the axial guide rail to make the steel pipe slide out of the clamp plate set after cutting.

[0017] As a further description of the above technical solution: the base is slidably connected with a water baffle for closing the liquid storage groove, and both are provided with springs, and the radial slide plate is driven to push against the water baffle.

[0018] As a further description of the above technical solution: a telescopic baffle is slidably connected to the circular saw cover, and the telescopic baffle is retracted with the circular saw blade cutting, and is extended to receive the cooling liquid pipe with the circular saw blade retracting.

[0022] As a further description of the above technical solution: it also includes the circular saw cover and the telescopic baffle, and a liquid guide tube is fixedly connected between the telescopic baffle and the guide frame.

[0023] In the above technical solution, the cutting machine for processing agricultural machinery mufflers provided by the present invention has the following beneficial effects: In use, the radial slide plate slides along the axial guide rail to the first end, and then the hydraulic cylinder drives the clamping plate assembly to close and fix the steel pipe.

[0039] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Please see Figures 1-12 This invention provides a technical solution: a cutting machine for processing agricultural machinery mufflers, comprising:

[0041] The planing unit includes a cutting tool and a drive disk arranged along the axis of the steel pipe 6. Both the cutting tool and the drive disk are mounted on the frame. The drive disk is a circular disk with its axis vertically arranged and is connected to the motor drive. The steel pipe 6 is transported along the axis by the rotating disk, so that the steel pipe 6 moves along the cutting tool to perform the planing operation.

[0042] Coolant tank 2 is used to hold coolant, facilitating its circulation and reuse. Figure 1 As shown, a axial guide rail 1 is provided on one side of the coolant tank 2, and a radial slide plate 3 is slidably connected to the axial guide rail 1, which can slide along the axial direction of the steel pipe 6 and is driven by a motor and a screw.

[0043] The circular saw is slidably connected to the radial slide plate 3, which is inclined and can slide along the radial slide plate 3 to move and cut the steel pipe 6. The circular saw is equipped with a motor 312 to drive the circular saw.

[0044] The fixing mechanism 5 includes a base 51 disposed on the radial slide plate 3. A clamping plate assembly is symmetrically arranged on the base 51 along the circular saw. The clamping plate assembly is used to fix the steel pipe 6. The clamping plate assembly is driven by the hydraulic cylinder 52 to clamp the steel pipe 6.

[0045] In use, the radial slide plate 3 slides along the axial guide rail 1 to the head end (to... Figure 1 For reference (the first end is the left end, and the last end is the right end), the hydraulic cylinder 52 then drives the clamping plate assembly to close and fix the steel pipe 6. Then the radial slide plate 3 is driven to slide along the axial guide rail 1. At this time, the clamping plate assembly can clamp the steel pipe 6 and move it axially to assist the cutter and drive disc in planing the steel pipe 6. At the same time, the circular saw slides with the radial slide plate 3 to cut the steel pipe 6. While cutting, the steel pipe 6 is pulled (planed). The pulling and cutting are combined to reduce the loading and unloading process and speed up the production speed. After cutting, the clamping plate assembly releases the steel pipe 6, and the radial slide plate 3 slides along the axial guide rail 1 to the end, so that the released uncut steel pipe 6 pushes out the cut steel pipe 6, realizing the unloading.

[0046] In another embodiment of the present invention, the clamping plate assembly includes a fixed clamping plate 54 and a movable clamping plate 53. The fixed clamping plate 54 is fixed to the base 51 by screws, and the movable clamping plate 53 has an inclined inner wall 532. Figure 9 As shown, a hydraulic cylinder 52 is fixedly connected to the movable clamping plate 53 by screws. The hydraulic cylinder 52 is equipped with a rotating rod 521 rotatably connected to the base 51. The base 51 has a corresponding rotating hole 511 for the rotating rod 521. Figure 8 and Figure 10 As shown, a limiting plate is provided on the rotating rod 521, allowing the hydraulic cylinder 52 to rotate the movable clamping plate 53. In use, the output end of the hydraulic cylinder 52 pushes the movable clamping plate 53 towards the fixed clamping plate 54. Subsequently, the inclined inner wall 532 of the movable clamping plate 53 adheres to the steel pipe 6. With the continued pushing of the hydraulic cylinder 52, the rotating rod 521 rotates along the rotating hole 511, causing the movable clamping plate 53 to move along the axis of the steel pipe 6, while simultaneously causing the inclined inner wall 532 to adhere to the steel pipe 6. Because the clamping plate assembly is symmetrically arranged, as... Figure 9 As shown, during the clamping process, the output direction of the hydraulic cylinder 52 is changed to tilt during the clamping process of the movable clamping plate 53. Compared with vertical fixation, the tilting direction has stronger fixation ability and has the freedom of the axial direction, reducing the vibration generated during cutting.

[0047] Preferably, the inner wall of the fixed clamp plate 54 and the movable clamp plate 53 is provided with a circumferential array of pads 531 made of soft metal, such as copper, which will contact the steel pipe 6 when the movable clamp plate 53 is pushed by the output end of the hydraulic cylinder 52 to move towards the fixed clamp plate 54, and then bend to fit the steel pipe 6 when the inclined inner wall 532 moves along the axis of the steel pipe 6, thereby reducing scratches on the surface of the steel pipe 6 caused by the movable clamp plate 53. When the clamp plate group is loosened, the radial sliding plate 3 slides along the axial guide rail 1 to the end, so that the loosened uncut steel pipe 6 pushes the cut steel pipe 6 out, and in the process, the pads 531 will vibrate with the movement of the steel pipe 6 to shake off the cuttings.

[0048] Preferably, the pads 531 can be arranged in a staggered manner, such as Figure 11 As shown, the staggered arrangement is used to limit the cooling liquid and reduce the gap caused by the pads 531, thereby reducing the cooling liquid entering between the clamp group and the steel pipe 6, limiting the cooling liquid flowing rapidly along the steel pipe 6 and the circular saw blade 30 during cutting, reducing the residence time, and avoiding uneven cooling caused by the residence of the cooling liquid.

[0049] In another embodiment of the present application, the circular saw machine comprises a circular saw cover 31 and a circular saw blade 30, the circular saw cover 31 is provided with a cooling liquid pipe 33 for outputting filtered cooling liquid in the cooling liquid tank 2, the base 51 is provided with a liquid storage tank 512, the fixed clamp plate 54 and the movable clamp plate 53 are both provided with a clamp backflow port 342, the clamp backflow port 342 is connected with the liquid storage tank 512, during cutting, the cooling liquid pipe 33 will continuously deliver cooling liquid to the cutting position, and the liquid storage tank 512 will be blocked, so that the cooling liquid in the liquid storage tank 512 will continuously accumulate with the cutting, and the liquid level in the liquid storage tank 512 will rise, during the cutting process, the circular saw blade 30 will continuously move towards the steel pipe 6 and enter the base 51, at this time, the circular saw blade 30 will act as a side wall of the liquid storage tank 512, thereby contacting the cooling liquid to cool itself, and as the moving distance increases, the contact area with the cooling liquid increases, thereby fully cooling the circular saw blade 30.

[0050] Preferably, the radial sliding plate 3 is driven to move by a hydraulic unit (hydraulic pump cooperating with a telescopic cylinder), the base 51 is slidably connected with a water baffle 55 for blocking the liquid storage tank 512, and a spring 552 is arranged between the base 51 and the water baffle 55, during cutting of the steel pipe 6, the radial sliding plate 3 is driven to move towards the steel pipe 6, at this time, the radial sliding plate 3 will push and compress the spring 552 and drive the water baffle 55 to block the liquid storage tank 512, and after cutting is completed, the radial sliding plate 3 is retracted, the spring 552 rebounds to push and reset the radial sliding plate 3 to open the liquid storage tank 512.

[0051] Preferably, the inner wall of the circular saw cover 31 is slidably connected with an extension baffle 32, and a telescopic pipe is arranged between the circular saw cover 31 and the extension baffle 32. The telescopic pipe, which can be an elastic member limited in the circular frame, acts as an elastic member and pushes the extension baffle 32 to extend out of the circular saw cover 31. The water baffle 55 is provided with a baffle 551 for blocking the extension baffle 32. When the circular saw blade 30 extends towards the steel pipe 6 along with the sliding of the radial slide plate 3, the baffle 551 blocks the extension baffle 32, so that the telescopic pipe is compressed, and at this time, the extension baffle 32 is retracted, which does not affect the normal cutting of the circular saw blade 30. After the cutting is completed, the radial slide plate 3 moves away from the steel pipe 6, and the extension baffle 32 extends to receive the part of the cooling liquid falling from the cooling liquid pipe 33 and the cooling liquid on the circular saw blade 30, so as to continuously cool the circular saw blade 30 when not cutting. The base 51 is provided with a circular saw backflow port 341 for discharging the cooling liquid overflowing in the extension baffle 32.

[0052] In still another embodiment of the present application, a damping mechanism 4 is further included, which comprises a guide frame 41 arranged between the planing unit and the circular saw machine. The bottom of the guide frame 41 is fixedly connected with a support through screws, and the bottom of the support is a cement base. A press roller 42 is slidably arranged on the guide frame 41 in the vertical direction and contacts the steel pipe 6. A weight is arranged on the press roller 42, which can be a sandbag or a lead block. The part of the steel pipe 6 away from the clamp block group vibrates much more than the part fixed by the clamp block group, especially the steel pipe 6 next to the planing unit. The vibration will cause patterns during planing, which affects the surface of the steel pipe 6. At this time, the press roller 42 is pulled against the steel pipe 6 by the weight, so as to achieve the purpose of damping and weaken the patterns during planing.

[0053] Preferably, the press roller 42 is connected with a counterweight frame 43 through a rope. The counterweight frame 43 is provided with a liquid outlet hole 431, and the counterweight frame 43 is filled with cooling liquid. The pump continuously injects cooling liquid into the counterweight frame 43 to increase the counterweight of the counterweight frame 43. During cutting, the power of the pump is increased, and at this time, the liquid outlet amount of the liquid outlet hole 431 is lower than the liquid inlet amount to increase the counterweight and assist in damping. After cutting is completed, the power of the pump is reduced, and at this time, the liquid outlet amount of the liquid outlet hole 431 is greater than the liquid inlet amount to reduce the pressing force on the steel pipe 6.

[0054] Preferably, the circular saw cover 31 and the telescopic baffle 32 are further included, the telescopic baffle 32 and the guide frame 41 are fixedly communicated with a liquid guide pipe 311, the telescopic baffle 32 is provided with a liquid outlet pipe 322 communicated with the liquid guide pipe 311, the inner wall of the liquid outlet pipe 322 is symmetrically provided with liquid blocking plates 321, the liquid outlet pipe 322 is made of elastic material, the circular saw cover 31 is provided with a clamping groove through which the liquid outlet pipe 322 passes, the liquid blocking plates 321 will limit the area of the liquid outlet pipe 322, so that only part of the cooling liquid will enter the liquid outlet pipe 322, when the telescopic baffle 32 is extended, the cooling liquid will flow down along the telescopic baffle 32, at this time, the cooling liquid entering the liquid outlet pipe 322 is relatively small, when cutting, the telescopic baffle 32 is retracted into the circular saw cover 31, at this time, the clamping groove clamps the liquid outlet pipe 322, so that the center of the liquid outlet pipe 322 is recessed, causing the two liquid blocking plates 321 to open, increasing the cooling liquid entering the liquid outlet pipe 322, which replaces the above-mentioned pump.

[0055] The part of the cooling liquid tank 2 facing the planing unit is provided with a side baffle 21, and the side baffle 21 is provided with a liquid return plate 22 to receive the cooling liquid leaked from the counterweight frame 43 for recycling.

[0056] Firstly, the radial sliding plate 3 slides to the first end along the axial guide rail 1, and the clamp plate combination is folded to fix the steel pipe 6, then the radial sliding plate 3 is driven to slide along the axial guide rail 1, at this time, the moving clamp plate combination can clamp the steel pipe 6 to move axially to assist the cutter and the driving disc to plane the steel pipe 6, at the same time, the circular saw machine slides with the radial sliding plate 3 to cut the steel pipe 6, at the time of cutting, the blocking plate 551 blocks the telescopic baffle 32, so that the telescopic pipe is compressed, at this time, the telescopic baffle 32 is retracted, the groove clamps the liquid outlet pipe 322, so that the center of the liquid outlet pipe 322 is recessed, causing the two liquid blocking plates 321 to open, increasing the cooling liquid entering the liquid outlet pipe 322, reducing the vibration of the steel pipe, after cutting, the radial sliding plate 3 moves away from the steel pipe 6, the telescopic baffle 32 extends to receive part of the cooling liquid falling from the cooling liquid pipe 33 and the cooling liquid on the circular saw blade 30, so that the circular saw blade 30 is continuously cooled without cutting. After the radial sliding plate 3 slides to the end along the axial guide rail 1, the steel pipe 6 is loosened and the radial sliding plate 3 is continuously driven to slide towards the first end, the uncut steel pipe pushes out the cut steel pipe 6, completing the discharging.

[0057] The above only describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
