Description

Technical Field

[0001] The invention relates to the technical field of metal pipe processing, grinding and polishing equipment, in particular to metal pipe processing equipment. Background Art

[0002] During the grinding and polishing process of the outer circle of metal pipes such as metal elbows, an outer circle polishing machine for the elbow is used. The two sets of abrasive belts on the outer circle polishing machine rotate relative to each other, and the metal elbow is inserted between the two sets of abrasive belts along the circular mouth of the outer circle polishing machine. The metal elbow is manually pushed on the outside of the circular mouth to achieve grinding and polishing of the metal elbow.

[0003] However, when the metal elbow is inserted between two sets of sanding belts for grinding, in order to ensure the tension of the sanding belts and make the sanding belts fit fully with the outer wall of the metal elbow, the distance between the two sanding belts is smaller than the outer diameter of the metal elbow. At this time, in order to stably insert one end of the metal elbow between the two sanding belts, it is necessary to manually and slowly insert the elbow between the two high-speed rotating sanding belts. In this process, it is easy for one end of the elbow to collide with the two sanding belts, causing the position of the sanding belts to shift or even damage the sanding belts. For this reason, we propose a metal pipe processing equipment. Summary of the Invention

[0048] Two connecting plates 3 are provided on the outside of one end of the insertion port 11, and two guide rails 31 are provided on the polishing machine body 1. The connecting plates 3 are provided with sliding grooves, and the connecting plates 3 are slidably sleeved on the outside of the guide rails 31 through the sliding grooves;

[0049] The polishing machine body 1 is provided with an adjustment mechanism 4, which is used to adjust the distance between the two connecting plates 3;

[0050] The adjustment mechanism 4 includes a first electric push rod 41, an adjustment frame 42 and an adjustment shaft 43. The first electric push rod 41 is fixedly mounted on the polishing machine body 1, and the output end of the first electric push rod 41 is fixedly connected to the adjustment frame 42. The adjustment frame 42 is Y-shaped and has two branch ends 421 on the adjustment frame 42. Both branch ends 421 are provided with an adjustment port 422. There are two adjustment shafts 43, which slide through the adjustment ports 422 respectively. One end of the adjustment shaft 43 is fixedly connected to the connecting plate 3.

[0051] Specific implementation process: When the distance between the two connecting plates 3 is adjusted, the first electric push rod 41 is operated to make the adjustment frame 42 move along the polishing machine body 1, and when the adjustment frame 42 moves, the adjustment shaft 43 is pushed through the adjustment openings 422 at the two branch ends 421 respectively. At this time, the connecting plates 3 are further moved in opposite directions under the limiting action of the guide rails 31 and the adjustment shaft 43, thereby realizing the synchronous adjustment of the positions of the two connecting plates 3 relative to the insertion opening 11.

[0056] The pusher 53 is mounted inside the support frame 51 and connected to the movable plate 54. The movable plate 54 is slidably connected to the support frame 51. The first inclined block 55 and the second inclined block 56 are alternately mounted on the movable plate 54.

[0057] The detection propulsion member 52 includes a fixed side plate 521, a rotating shaft 522, a feed wheel 523, a drive motor 524, a synchronous drive member 525 and a detection member 526.

[0061] As a supplementary explanation, the synchronous driving member 525 includes a synchronous gear, a synchronous belt, and a tensioning rod. There are multiple synchronous gears, each of which is fixedly sleeved on one end of the multiple rotating shafts 522. The synchronous belt is used to rotate the multiple synchronous gears. There are multiple tensioning rods, each of which is installed on one of the fixed side plates 521. The multiple tensioning rods are used to keep the synchronous belt in a tensioned state.

[0062] Specific implementation process: When processing, grinding and polishing a metal bend of a shorter length, when the staff moves one end of the metal bend toward the two sets of feed wheels 523 at the insertion port 11, the two distance sensors 5262 first detect the distance of the metal bend, and simultaneously send an electrical signal to the controller, and the controller sends an electrical signal. At this time, the first electric push rod 41 operates, thereby increasing the distance between the two sets of feed wheels 523, and then when the metal bend is inserted, the two sets of feed wheels 523 are both close to the outside of the metal bend;

[0063] Subsequently, the driving motor 524 is operated, thereby rotating one of the rotating shafts 522. At this time, under the connection of the synchronous driving member 525, multiple rotating shafts 522 are rotated synchronously. At this time, the two sets of feed wheels 523 rotate in opposite directions, thereby assisting the metal bend to be pushed into the insertion port 11. At the same time, in order to ensure the stability of the metal bend, the staff still needs to hold the metal bend by hand to ensure the stability of the metal bend.

[0064] The push member 53 includes a second electric push rod 531 and a push frame 532. The second electric push rod 531 is fixedly installed inside the support frame 51, and the output end of the second electric push rod 531 is fixedly connected to the push frame 532.

[0065] The expansion member 7 includes a first contact roller 71, a support seat 72, an expansion rod 73, a connecting spring 74, an arc-shaped plate 75, and an expansion roller 76. The expansion rod 73 slides through the side of the support frame 51 near the insertion port 11. The support seat 72 is located inside the support frame 51. The first contact roller 71 is rotatably connected to the support seat 72. The first contact roller 71 is slidably connected to the first inclined block 55.

[0066] The connecting spring 74 is sleeved on the outside of the spreading rod 73, and the two ends of the connecting spring 74 are fixedly connected to the support seat 72 and the support frame 51 respectively;

[0067] The other end of the spreading rod 73 is fixedly connected to the arc plate 75, and a plurality of spreading rollers 76 are provided. The plurality of spreading rollers 76 are evenly distributed around the arc plate 75, and the spreading rollers 76 are rotatably connected to the arc plate 75. The plurality of spreading rollers 76 are used to spread the grinding belt 2.

[0068] Specific implementation process: When the two support frames 51 are connected by the connecting rod 872, the support frames 51 move in the direction away from each other, and the support frames 51 synchronously drive the spreading rod 73 to move. At this time, the turntable on the polishing machine body 1 stops rotating, and the two sets of spreading rollers 76 originally located between the two grinding belts 2 also move synchronously in opposite directions. The two sets of spreading rollers 76 spread the grinding belts 2 during the transmission process, so that the metal bend enters the insertion port 11. When the two sets of spreading rollers 76 are in the spread state, the two sets of grinding belts 2 are located at the insertion port 11. The two sets of grinding belts 2 are located on the outside of the metal bend to be polished.

[0069] Subsequently, the second electric push rod 531 runs, further causing the movable plate 54 to synchronously drive the first inclined block 55 and the second inclined block 56 to move. When the first inclined block 55 moves, the first contact roller 71 is under the reverse elastic force of the connecting spring 74, so that the first contact roller 71 is always in contact with the inclined surface of the first inclined block 55. At this time, one end of the expansion rod 73 moves toward the inside of the support frame 51, and when the expansion rod 73 moves, it drives multiple expansion rollers 76 to deviate from the grinding belt 2 through the arc plate 75. At this time, the grinding belt 2 is tautly set on the outside of the metal bend, so as to achieve the next step of fully grinding the metal bend.

[0070] The limiting member 8 includes a lower pressure rod 81, a connecting seat 82, a second contact roller 83, a buffer spring 84, a wedge block 85, a synchronization block 86, a buffer connecting member 87 and a correction member 88.

[0071] A buffer spring 84 is sleeved on the outside of the lower pressure rod 81, and the two ends of the buffer spring 84 are fixedly connected to the connecting seat 82 and the support frame 51 respectively. The other end of the lower pressure rod 81 is fixedly connected to the wedge block 85. One side of the synchronization block 86 is provided with a pushing inclined surface 861, and the wedge block 85 is slidably connected to the pushing inclined surface 861. A buffer connector 87 is provided on the outside of the support frame 51 and is connected to the synchronization block 86.

[0072] The deviation correcting member 88 is installed on the synchronization block 86.

[0073] The buffer connector 87 includes a connecting frame 871, a connecting rod 872 and a support spring 873. One end of the connecting frame 871 is fixedly connected to the synchronization block 86. Two connecting rods 872 are provided, and the other end of the connecting frame 871 is slidably sleeved on the outside of the two connecting rods 872. Both ends of the connecting rod 872 are fixedly installed with fixed blocks 874, and the fixed blocks 874 are fixedly installed on the outside of the support frame 51. The support spring 873 is sleeved on the outside of the connecting rod 872, and the two ends of the support spring 873 are respectively fixedly connected to the connecting frame 871 and the fixed plate.

[0074] The correction member 88 includes an extension frame 881, a support shaft 882, a micro motor 883 and a correction roller 884. One end of the extension frame 881 is fixedly connected to the synchronization block 86.

The two ends of the correction rollers 884 are respectively fixedly connected to the correction plates 885.

[0075] Specific implementation process: In this embodiment, when the turntable drives the two sets of grinding belts 2 to rotate relative to the polishing machine body 1, the correction roller 884 is vertically offset from the grinding belt 2, and the support roller 76 is also offset from the grinding belt 2, so as not to affect the synchronous rotation of the grinding belt 2 with the turntable to grind the bent pipe;

[0076] At the same time, when the two second electric push rods 531 are running, the second inclined block 56 is driven to move through the moving plate 54, and the synchronous block 86 is pushed. Since the synchronous block 86 is connected to the connecting frame 871, the two synchronous blocks 86 further move toward each other, causing the two sets of correcting rollers 884 to move toward each other until the two sets of correcting rollers 884 move to the outside of the grinding belt 2 respectively. At the same time, the correcting plate 885 is used to correct the grinding belt 2 during the transmission process. Subsequently, the micro motor 883 is operated to rotate the support shaft 882 90°, further causing the two correcting rollers 884 to deviate from the grinding belt 2. At this time, the turntable rotates, causing the two sets of grinding belts 2 to surround the metal bend in the feeding process for circular transmission grinding and polishing. Example 2

[0077] See also Figures 1 to 3 and Figure 6 , Example 2 is a further explanation of the guide mechanism 6 in Example 1, specifically: the guide mechanism 6 includes a fixed shell 61, a guide sleeve 62, a guide spring 63, a guide rod 64, a guide shell 65 and a guide wheel 66, two fixed shells 61 are provided, and the two fixed shells 61 are respectively located on the outside of the support frame 51, the fixed shell 61 is fixedly installed on the polishing machine body 1, the guide sleeve 62 is fixedly passed through the fixed shell 61, the guide spring 63 is located inside the guide sleeve 62, the two ends of the guide spring 63 are respectively fixedly connected to the guide sleeve 62 and the guide rod 64, the guide rod 64 slides through the guide sleeve 62, and the other end of the guide rod 64 is fixedly connected to the guide shell 65, a plurality of guide wheels 66 are provided, and the plurality of guide wheels 66 are rotatably connected to the guide shell 65 at equal distances, and the guide shell 65 is provided with a guide opening at the position of the guide wheel 66;

The two sets of feed wheels 523 guide and limit the metal bend tube. Simultaneously, the four sets of guide wheels 66 are also distributed on the outer side of the metal bend tube, thereby guiding and limiting the metal bend tube.

[0079] At the same time, the multiple guide wheels 66 can be adjusted according to the metal bends of different diameters under the connection of the guide rod 64, the guide spring 63 and the guide sleeve 62, without affecting the stable movement and grinding of the metal bends.
