Description

Technical Field

[0001] The present invention relates to the technical field of metal pipe processing, grinding and polishing equipment, and specifically relates to a metal pipe processing and treatment equipment. Background Technique

[0002] During the grinding and polishing process of the outer circle of metal pipes such as metal bent pipes, a bent pipe outer circle polishing machine is used. Two sets of abrasive belts on the outer circle polishing machine rotate relative to each other, and the metal bent pipe is inserted between the two sets of abrasive belts along the circular opening of the outer circle polishing machine. Then, workers push the metal bent pipe outside the circular opening to achieve grinding and polishing of the metal bent pipe.

[0003] However, during the process of grinding the metal bent pipe inserted between the two sets of abrasive belts, in order to ensure the tension of the abrasive belts so that the abrasive belts can fully adhere to the outer wall of the metal bent pipe, the distance between the two abrasive belts is smaller than the outer diameter of the metal bent pipe. At this time, in order to enable one end of the metal bent pipe to be stably inserted between the two abrasive belts, workers need to slowly insert the bent pipe between the two high-speed rotating abrasive belts. During this process, it is easy for one end of the bent pipe to collide with the two abrasive belts, causing the position of the abrasive belts to shift, and even causing damage to the abrasive belts. For this reason, we propose a metal pipe processing and treatment equipment. Summary of the Invention

There are multiple tensioning rods, and the multiple tensioning rods are installed on one of the fixed side plates 521. The multiple tensioning rods are used to keep the synchronous belt in a tensioned state. Specific implementation process: During the process of processing, grinding, and polishing a short metal elbow pipe, when the staff moves one end of the metal elbow pipe towards the two feeding wheels 523 at the insertion port 11, the two distance sensors 5262 first detect the distance of the metal elbow pipe and simultaneously send electrical signals to the controller. Then the controller sends an electrical signal. At this time, the first electric push rod 41 operates, so that the distance between the two feeding wheels 523 is adjusted to be larger. Then, until the metal elbow pipe is inserted, both feeding wheels 523 are closely attached to the outer side of the metal elbow pipe. Subsequently, the drive motor 524 operates, so that one of the rotating shafts 522 rotates. At this time, under the connection of the synchronous drive member 525, multiple rotating shafts 522 rotate synchronously. At this time, the two feeding wheels 523 rotate in opposite directions to assist in pushing the metal elbow pipe into the insertion port 11. At the same time, in order to ensure the stability of the metal elbow pipe, the staff still needs to hold the metal elbow pipe by hand to ensure its stability.

The spreader rollers 76 are rotatably connected to the arc plate 75. The plurality of spreader rollers 76 are used to spread the grinding belt 2.

[0024] Specific implementation process: When the two support frames 51 move away from each other under the connection of the connecting rod 872, the support frames 51 drive the spreading rods 73 to move synchronously. At this time, the turntable on the polishing machine body 1 stops rotating, and the two groups of spreading rollers 76 originally located between the two grinding belts 2 also move in opposite directions synchronously. The two groups of spreading rollers 76 spread the grinding belts 2 during transmission. When the metal bent pipe enters the insertion port 11, the two groups of grinding belts 2 at the insertion port 11 are in the spread state by the two groups of spreading rollers 76, and the two groups of grinding belts 2 are located outside the metal bent pipe to be ground. Subsequently, the second electric push rod 531 operates, further causing the moving plate 54 to drive the first inclined block 55 and the second inclined block 56 to move synchronously. When the first inclined block 55 moves, the first contact roller 71 is always in contact with the inclined surface of the first inclined block 55 under the reverse elastic force of the connecting spring 74. At this time, one end of the spreading rod 73 moves towards the inside of the support frame 51. When the spreading rod 73 moves, the arc-shaped plate 75 drives the multiple spreading rollers 76 to deviate from the grinding belt 2. At this time, the grinding belt 2 is tensioned and arranged outside the metal bent pipe to achieve the next step of fully grinding the metal bent pipe.

And due to the connection of the synchronization block 86 by the connecting frame 871, further, the two synchronization blocks 86 move towards each other, so that the two groups of deviation rectifying rollers 884 move towards each other until the two groups of deviation rectifying rollers 884 respectively move to the outside of the grinding belts 2. At the same time, the deviation rectifying plates 885 correct the deviation of the grinding belts 2 during the transmission process.
