Description

Technical Field

[0001] The present invention relates to the technical field of pipe processing, and particularly to a pipe chamfering device. Background Art

[0002] Pipes are widely used. When using pipes, it is often necessary to chamfer their ends to remove burrs at the ends of the pipes. Pipes are widely used in life. In actual use, pipes of different lengths are often required. Therefore, it is necessary to cut the pipes according to requirements and cut the pipes into different lengths to adapt to different applications. After the pipes are cut, burrs will be generated at their cut ends. These burrs will scratch the operators or damage the packaging during operation or handling. Therefore, it is necessary to round the ends of the pipes to clean up the burrs. The existing chamfering devices chamfer the ends of the pipes by driving the cutting tools to rotate along the ends of the pipes to remove the burrs. However, there are often depressions or protrusions at the edges of the ends of the pipes. After the clamping mechanism of such chamfering devices clamps the pipes, the cutting tools grind their ends. The protruding parts of the pipes will collide violently with the cutting tools, which is likely to damage the pipes and also affect the service life of the cutting tools; for the depressed parts of the pipes, the cutting tools cannot cut, which affects the grinding effect of the pipes. After the grinding is completed, the ends of the pipes need to be further processed, which seriously affects the grinding efficiency of the pipes. In addition, the clamping mechanism of such chamfering devices can only clamp pipes with a fixed diameter. When pipes with different diameters need to be ground, the corresponding clamping mechanism needs to be replaced, which also affects the production efficiency of the pipes. In addition, the current chamfering devices mainly rely on manual feeding / discharging, resulting in low grinding efficiency of the pipes and increased processing costs. Summary of the Invention

[0003] The main object of the present invention is to overcome the problems of poor chamfering effect of the existing pipe chamfering devices, damage to the pipes and incomplete cutting during the chamfering process, and provide a pipe chamfering device that improves the chamfering effect of the ends of the pipes.

[0004] The secondary object of the present invention is to overcome the problems that the existing pipe chamfering devices cannot automatically feed and discharge materials and have low automation, and provide a pipe chamfering device that reduces the use of manpower and improves the chamfering efficiency of the pipes.

[0005] To solve the above problems, the present invention adopts the following technical solutions to achieve:

[0006] A pipe chamfering device of the present invention includes a chamfering device and a material transporting device for feeding the chamfering device. The material transporting device includes a first rack and a second rack arranged side by side in the front-rear direction. The first rack and the second rack are spaced apart. The chamfering device includes chamfering mechanisms symmetrically arranged at the left and right ends of the second rack. The chamfering mechanism includes a frame body. A chamfering assembly and a clamping assembly for clamping the pipe are provided on the frame body. The chamfering assembly is located outside the clamping assembly. The chamfering assembly includes a tool disk. An external chamfering mechanism and an internal chamfering mechanism are respectively arranged on the left and right sides of the front surface of the tool disk. The external chamfering mechanism includes a first mounting block and a first cutter head slidably arranged on the first mounting block. A first elastic member is further provided on the first mounting block. The first elastic member is used to drive the first cutter head to abut against the outer edge of the pipe end. The internal chamfering mechanism includes a second mounting block and a second cutter head slidably arranged on the second mounting block. A second elastic member is further provided on the second mounting block. The second elastic member is used to drive the second cutter head to abut against the inner edge of the pipe end.

[0007] In this solution, the material transporting device transports the pipe to the chamfering mechanism. The clamping assembly of the chamfering mechanism clamps the pipe. Then, the chamfering assembly of the chamfering mechanism chamfers the end of the pipe. Specifically, the external chamfering mechanism of the chamfering assembly chamfers the outer edge of the pipe end, and the internal chamfering mechanism chamfers the inner edge of the pipe end. Among them, both the first cutter head and the second cutter head are triangular cutter heads. When the external chamfering mechanism chamfers the outer edge of the pipe, the center of the tool disk is located on the axis of the pipe. The first elastic member drives the first cutter head to abut against the outer edge of the pipe and perform cutting. By setting the first elastic member, the fitting degree between the first tool and the outer edge of the pipe end face is improved. When there is a protrusion on the outer edge of the pipe, the protrusion part presses the first elastic member, causing the first cutter head to abut against the protrusion part and cut it flat. When there is a depression on the outer edge of the pipe, the first elastic member drives the first tool to enter the depression and cut it flat. The internal chamfering mechanism for chamfering the inner edge of the pipe end has the same structure and working process as the external chamfering mechanism, which will not be elaborated here. In addition, driven by the first elastic member, the first cutter head reduces the scraping of the cutting edge against the pipe wall at the protrusion and depression, avoiding great damage to the tool caused by scraping. It should be noted that the above-mentioned protrusions and depressions refer to the minute deformations generated during the production or cutting of the pipe, rather than the obvious convex blocks or deep pits existing at the pipe end.

Since the plurality of clamping blocks on the left base block and the plurality of clamping blocks on the right base block are arranged alternately, when clamping a pipe with a smaller diameter, the clamping blocks on the left base block and the clamping blocks on the right base block bite each other, that is, the accommodation space between the two first V - shaped grooves is reduced, realizing the clamping of the pipe with a smaller diameter.

Specific Embodiments

[0041] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0042] Embodiment: A pipe chamfering device in this embodiment, as Figures 1 to 18 shown, includes a chamfering device and a material conveying device for feeding the chamfering device. The material conveying device includes a first frame 1 and a second frame 2 arranged side by side in the front-rear direction. The first frame 1 and the second frame 2 are spaced apart. A pipe loading machine is provided at one end of the first frame 1. The chamfering device includes chamfering mechanisms symmetrically arranged at the left and right ends of the second frame 2. The chamfering mechanism includes a frame body 3. A chamfering assembly and a clamping assembly for clamping the pipe are provided on the frame body 3. The chamfering assembly is located outside the clamping assembly. The clamping assembly includes first base blocks 4 and second base blocks 5 symmetrically arranged left and right. Both the first base block 4 and the first base block 4 are slidably arranged along the left-right direction of the frame body 3. A plurality of clamping blocks 6 are spacedly arranged on the inner side surface of the first base block 4. A plurality of clamping blocks 6 are spacedly arranged on the inner side surface of the second base block 5. The plurality of clamping blocks 6 on the first base block 4 and the plurality of clamping blocks 6 on the second base block 5 are staggered. A first V-shaped groove 7 is provided inside the clamping block 6. The first V-shaped groove 7 penetrates through the clamping block 6 from front to back. A driving module for synchronously driving the first base block 4 and the second base block 5 to approach / separate from each other is also provided on the frame body 3. The chamfering assembly includes a tool disc 8. An external chamfering mechanism and an internal chamfering mechanism are respectively provided on the left and right sides of the front surface of the tool disc 8. The external chamfering mechanism includes a first mounting block 9. A first tool holder 21 slidably arranged along the left-right direction is provided on the first mounting block 9. A first tool head 10 is fixedly connected to the first tool holder 21. A first baffle 22 is provided on the left side of the first tool holder 21. A first elastic member 11 is provided between the first baffle 22 and the first tool holder 21. The first elastic member 11 is used to drive the first tool head 10 to abut against the outer edge of the pipe end; the internal chamfering mechanism includes a second mounting block 12. A second tool holder 23 slidably arranged along the left-right direction is provided on the second mounting block 12. A second tool head 13 is fixedly connected to the second tool holder 23. A second baffle 24 is provided on the left side of the second tool holder 23. A second elastic member 14 is provided between the second baffle 24 and the second tool holder 23. The second elastic member 14 is used to drive the second tool head 13 to abut against the inner edge of the pipe end.

[0043] In this solution, the material conveying device transports the pipe to the chamfering mechanism. The clamping component of the chamfering mechanism clamps the pipe, and then the chamfering component of the chamfering mechanism chamfers the end of the pipe. Specifically, the driving module drives the first base block 4 and the second base block 5 to approach each other until the clamping blocks 6 on the first base block 4 and the clamping blocks 6 on the second base block 5 are in contact with the outer wall of the pipe. The pipe is restricted in the first V-shaped grooves 7 of the clamping blocks 6 on both sides, realizing the clamping of the pipe. Since the multiple clamping blocks 6 on the first base block 4 and the multiple clamping blocks 6 on the second base block 5 are staggered, when clamping a pipe with a smaller diameter, the clamping blocks 6 on the first base block 4 and the clamping blocks 6 on the second base block 5 bite each other, that is, the accommodation space between the two first V-shaped grooves 7 is reduced, realizing the clamping of a pipe with a smaller diameter. Then, the outer chamfering mechanism of the chamfering component chamfers the outer edge of the pipe end, and the inner chamfering mechanism chamfers the inner edge of the pipe end. Among them, both the first cutter head 10 and the second cutter head 13 are triangular cutter heads. When the outer chamfering mechanism chamfers the outer edge of the pipe, the center of the cutter head disk 8 is located on the axis of the pipe. The first elastic member 11 drives the first cutter head 10 to abut against the outer edge of the pipe and perform cutting. By setting the first elastic member 11, the fitting degree between the first cutter and the outer edge of the pipe end face is improved. When there is a protrusion on the outer edge of the pipe, the protrusion part presses the first elastic member 11, causing the first cutter head 10 to abut tightly against the protrusion part and cutting it flat. When there is a depression on the outer edge of the pipe, the first elastic member 11 drives the first cutter to enter the depression and cut it flat. The inner chamfering mechanism for chamfering the inner edge of the pipe end has the same structure and working process as the outer chamfering mechanism, which will not be elaborated here. In addition, driven by the first elastic member 11, the first cutter head 10 reduces the scraping between the cutting edge and the pipe wall at the protrusion and depression, avoiding great damage to the cutter caused by scraping. It should be noted that the above-mentioned protrusions and depressions refer to the minute deformations generated during the production or cutting of the pipe, rather than the obvious convex blocks or deep pits existing at the pipe end. By adjusting the distance between the first base block 4 and the second base block 5, the clamping of pipes with different diameters can be realized, and the operation is convenient.

[0044] As Figure 4As shown, a plurality of first auxiliary clamping blocks 15 are provided on the first base block 4. The first auxiliary clamping blocks 15 correspond one by one to the clamping blocks 6 on the second base block 5. Two first inclined surfaces 16 are symmetrically arranged above and below the first auxiliary clamping blocks 15. The two first inclined surfaces 16 respectively match the upper inclined surface and the lower inclined surface of the first V-shaped groove 7 of the corresponding clamping block 6 on the second base block 5. A plurality of second auxiliary clamping blocks 17 are provided on the second base block 5. The second auxiliary clamping blocks 17 correspond one by one to the corresponding clamping blocks 6 on the first base block 4. Two second inclined surfaces 18 are symmetrically arranged above and below the second auxiliary clamping blocks 17. The two second inclined surfaces 18 match the upper inclined surface and the lower inclined surface of the first V-shaped groove 7 of the corresponding clamping block 6 on the first base block 4. Second V-shaped grooves 19 are provided on both the first auxiliary clamping blocks 15 and the second auxiliary clamping blocks 17. The second V-shaped grooves 19 are through grooves. The upper inclined surface of the second V-shaped groove 19 is in the same plane as the upper inclined surface of the first V-shaped groove 7, and the lower inclined surface of the second V-shaped groove 19 is in the same plane as the lower inclined surface of the first V-shaped groove 7. During actual work, the first base block 4 and the second base block 5 approach each other to clamp the pipe. Specifically, the pipe is clamped between the first V-shaped groove on the clamping block on the first base block 4 and the first V-shaped groove 7 on the clamping block on the second base block 5. When the diameter of the pipe is small, the plurality of clamping blocks on the first base block 4 and the plurality of clamping blocks on the second base block engage with each other. The two first inclined surfaces of the first auxiliary clamping block on the first base block 4 respectively fit the upper inclined surface and the lower inclined surface of the first V-shaped groove 7 of the corresponding clamping block on the second base block, and the two second inclined surfaces of the second auxiliary clamping block on the second base block 5 respectively fit the upper inclined surface and the lower inclined surface of the first V-shaped groove 7 of the corresponding clamping block on the first base block. By providing the first auxiliary clamping block and the second auxiliary clamping block, the purpose of improving the stability of clamping the pipe is achieved.

[0045] On the frame body 3, there are two third sliding rails symmetrically arranged left and right. The third sliding rails are arranged along the left and right direction of the frame. Sliders are slidably arranged in the third sliding rails. Bases are provided at the bottoms of the first base block 4 and the second base block 5. The bases of the first base block 4 and the second base block 5 are respectively connected to the sliders in the two third sliding rails. The driving module is located below the clamping assembly. The driving module includes a lifting block 52, two V-shaped swing arms 53 symmetrically arranged left and right on both sides of the lifting block 52, and a cylinder for driving the lifting block 52 to lift. The two V-shaped swing arms 53 respectively correspond to the bases of the first base block 4 and the second base block 5. The bent part of the V-shaped swing arm 53 is rotatably connected to the frame body 3. A first chute 54 is provided longitudinally at the lower end of the base. A first roller 55 is slidably arranged in the first chute 54. One end of the V-shaped swing arm 53 is rotatably connected to the first roller 55 in the corresponding first chute 54 on one side. Second chutes 56 are symmetrically arranged left and right on the lifting block 52. The second chutes 56 are arranged horizontally. Second rollers 57 are slidably arranged in the second chutes 56. The other end of the V-shaped swing arm 53 is rotatably connected to the second roller 57 in the corresponding second chute 56 on one side. When it is necessary to clamp the pipe, the cylinder drives the lifting block 52 to descend. At this time, the lifting block 52 pulls the V-shaped swing arm 53 to rotate downward. The two V-shaped swing arms 53 respectively drive the first base block 4 and the second base block 5 to approach each other until the pipe is clamped. After the chamfering of the pipe is completed, the cylinder drives the lifting block 52 to rise. At this time, the lifting block 52 pulls the V-shaped swing arm 53 to rotate upward. The two V-shaped swing arms 53 respectively drive the first base block 4 and the second base block 5 to move away from each other until the pipe is released.

[0046] As Figure 3 shown, the clamping assembly further includes a material blocking structure for limiting the pipe. The material blocking structure is located directly behind the clamping assembly. The material blocking structure includes a material blocking plate 20 and a lifting module for driving the material blocking plate 20 to lift. During actual work, the lifting module drives the material blocking plate 20 to move down to directly behind the clamping assembly. The material blocking plate 20 restricts the pipe at the chamfering position.

By providing the grinding mechanism, the end face of the end of the pipe can be ground.

[0050] As Figure 14As shown in the figure, a transmission mechanism is provided on the first rack 1. The transmission mechanism includes a plurality of first transmission wheels 31 arranged at intervals in the left-right direction of the first rack 1, a material transfer plate 32 arranged between adjacent first transmission wheels 31, and a first lifting structure for driving the material transfer plate 32 to lift and lower. The top surface of the material transfer plate 32 is inclined downward from front to back. A material storage mechanism and a material transportation mechanism are provided on the second rack 2. The material storage mechanism includes a feeding assembly and a plurality of material storage plates 33 arranged at intervals in the left-right direction of the second rack 2. The feeding assembly includes a plurality of folding plates 34 rotatably arranged on the second rack 2 and a first driving structure for driving all the folding plates 34 to rotate synchronously. The material storage plates 33 are arranged vertically. The top surface of the material storage plate 33 is provided with a first material storage notch 35 and a second material storage notch 36 in the front-rear direction. The material storage plate 33 includes a first partition block 37 and a second partition block 38. The first partition block 37 is located between the first material storage notch 35 and the second material storage notch 36. The top surface of the first partition block 37 is inclined downward from front to back. The second partition block 38 is located at the rear end of the second notch. The top surface of the second partition block 38 is inclined downward from front to back. The second partition block 38 extends out of the second rack 2 and is higher than the first partition block 37. The material transfer plate 32 is used to transfer the pipe to the first material storage notch 35. The folding plate 34 includes a first material transportation plate 39 and a second material transportation plate 40 connected in sequence from front to back. The top surface of the second material transportation plate 40 is higher than the top surface of the first material transportation plate 39. The top surface of the first material transportation plate 39 is inclined downward from front to back. The top surface of the second material transportation plate 40 is inclined downward from front to back. The first material transportation plate 39 corresponds to the first material storage notch 35. The second material transportation plate 40 corresponds to the second material storage notch 36. The folding plate 34 includes a horizontal state and a vertical state. When the folding plate rotates to the vertical state, the top surface of the second material transportation plate 40 is higher than the top surface of the second material storage notch 36. When the folding plate 34 is flipped to the horizontal state, the plate body of the second material transportation plate 40 is lower than the material storage plate 33. The material transportation mechanism includes a plurality of second transmission wheels 41 arranged at intervals in the left-right direction of the second rack 2 and a second driving structure for driving all the second transmission wheels 41 to rotate synchronously. The transmission path of the second transmission wheels 41 corresponds to the axis of the second material storage notch 36. The second transmission wheels 41 are higher than the bottom surface of the second material storage notch 36. Both the first transmission wheels 31 and the second transmission wheels 41 are provided with third V-shaped grooves for accommodating pipes. The center of the third V-shaped groove of the second transmission wheels 41 corresponds to the clamping position of the clamping assembly. The material transportation mechanism is used to transfer the pipes in the second material storage notch 36 to the chamfering mechanism and transport the pipes with chamfering completed away from the second rack.During actual operation, the pipe is transported to the first rack 1 by the existing pipe loading machine and pushed along the first transmission wheel 31 to a predetermined position. Then, the transfer plate 32 rises. After the pipe is lifted by the transfer plate 32, it rolls along the inclined surface of the transfer plate 32 into the first storage notch 35 of the storage plate 33. Next, the folding plate 34 rotates to the vertical state. The first material transport plate 39 pushes the pipe in the first storage notch 35 to the top surface of the first partition block 37. At this time, the side wall of the second material transport plate 40 restricts the pipe on the top surface of the first partition block 37. Then, the first driving structure drives all the folding plates 34 to rotate from the vertical state to the horizontal state. At this time, the second material transport plate 40 moves away. Then, the pipe on the top surface of the first partition block 37 rolls into the second storage notch 36. At this time, the first storage notch 35 is emptied. The transfer plate 32 continues to transport the pipe to the first storage notch 35. The second driving structure drives the second transmission wheel 41 to transport the pipe to the chamfering mechanism. After the pipe is chamfered, the material transport mechanism transports the chamfered pipe away from the chamfering mechanism. At this time, the folding plate rotates to the vertical state again. The second material transport plate 40 pushes the processed pipe in the second storage notch 36 to the top surface of the second partition block 38. The pipe rolls out of the second rack 2 along the top surface of the second partition block 38. The first material transport plate 39 pushes the pipe in the first storage notch 35 to the top surface of the first partition block 37. At this time, the side wall of the second material transport plate 40 restricts the pipe on the top surface of the first partition block 37. Then, the first driving structure drives all the folding plates 34 to fold from the vertical state to the horizontal state. At this time, the second material transport plate 40 moves away. Then, the pipe on the top surface of the first partition block 37 rolls into the second storage notch 36... and so on in a cycle. It should be noted that only a single pipe is temporarily stored in the first storage notch 35 and the second storage notch 36. In this embodiment, a receiving rack 47 is provided at the rear side of the second rack 2. The front end of the receiving rack 47 is located below the second partition block 38. After the pipe rolls out of the second rack 2 along the top surface of the second partition block 38, it enters the receiving rack 47.

[0051] As Figure 1 shown, the storage plate 33 extends towards the first rack 1. The front end of the first storage notch 35 of the storage plate 33 and the rear end of the transfer plate 32 are located in the same vertical plane. The bottom surface of the first storage notch 35 is inclined downward from front to back. In this embodiment, the top surface of the transfer plate 32 and the bottom surface of the first storage notch 35 have the same inclination angle, which is convenient for the pipe to roll from the transfer plate 32 into the first storage notch 35.

[0052] As Figure 14As shown in the figure, a discharge plate 48 and a second lifting structure for driving the discharge plate 48 to lift are further provided on the first rack. The discharge plate 48 is arranged in a staggered manner with the material transfer plate 32, and the top surface of the discharge plate 48 is inclined downward from the rear to the front. During actual operation, when the staff discovers that the pipes on the first rack 1 are bent, flattened, etc., the second lifting structure is activated. The second lifting structure drives the discharge plate to rise, and the discharge plate lifts up such defective pipes. The defective pipes roll out of the first rack 1 along the discharge plate.

[0053] As Figure 14 and 15 shown in the figure, a first position sensor 43 for sensing the position of the pipe is provided on the first rack 1. Second position sensors 44 for sensing the position of the pipe are provided at both ends of the second rack 2. A first detection sensor 49 for sensing the pipe is provided on the second rack. The first detection sensor 49 corresponds to the first storage notch 35. A second detection sensor 50 for sensing the pipe is further provided on the second rack 2. The second detection sensor 50 corresponds to the second storage notch 36. During actual operation, the pipe feeding machine transports the pipe to be chamfered to the first transfer wheel 31 at the end of the first rack 1 and pushes the pipe to be sequentially transported along a plurality of first transfer wheels 31. After the pipe triggers the first position sensor 43, the pipe feeding machine stops pushing the pipe. At this time, the material transfer plate 32 rises, and the pipe rolls into the first storage notch 35 along the inclined surface of the material transfer plate 32. Then the material transfer plate 32 descends and resets. The pipe in the first storage notch 35 triggers the first detection sensor 49. Then the first driving structure drives the folding plate 34 to rotate to the vertical state. The first material transporting plate 39 pushes the pipe in the first storage notch 35 to the top surface of the first partition block 37. At this time, the side wall of the second material transporting plate 40 restricts the pipe on the top surface of the first partition block 37. Then the first driving structure drives all the folding plates 34 to rotate from the vertical state to the horizontal state. At this time, the second material transporting plate 40 moves away. Then the pipe on the top surface of the first partition block 37 rolls into the second storage notch 36. At this time, the first storage notch 35 is emptied, and the material transfer plate 32 continues to transfer the pipe to the first storage notch 35. The material transporting mechanism transports the pipe in the second storage notch 36 to the chamfering mechanism at one end of the second rack 2. At this time, the end of the pipe triggers the corresponding second position sensor 44, and the lifting module drives the baffle 20 to descend to block the end of the pipe. At this time, the material transporting mechanism stops working. Then the chamfering mechanism chamfers one end of the pipe. After one end of the pipe is chamfered, the material transporting mechanism transports the pipe to the chamfering mechanism at the other end of the second rack 2. Then the chamfering mechanism chamfers the other end of the pipe. After chamfering is completed, the material transporting mechanism completely transports the pipe back onto the second rack 2. At this time, the pipe triggers the second detection sensor 50, and the first driving structure drives the folding plate 34 to rotate to the vertical state, realizing transporting the pipe away from the second rack 2.
