Technical Field

[0001] The invention relates to the technical field of steel pipe processing, in particular to a fully automatic cutting device for stainless steel pipe production. Background Art

[0002] Traditional stainless steel pipe cutting usually uses high-speed grinding wheel cutting machines or plasma cutting equipment. Although the cutting efficiency is high, high-decibel noise and obvious vibration will be generated during use, which has a serious impact on the surrounding environment and the health of operators.

In order to improve the cutting quality and accuracy, it is often necessary to configure complex clamping devices or cumbersome auxiliary mechanisms, which leads to increased operating difficulty and maintenance costs.

[0028] The working principle of the fully automatic cutting equipment for stainless steel pipe production disclosed in the present invention is as follows: insert the steel pipe into the outer casing 209 (first, push the downward pressing feeding lever 213 to move the feeding transmission belt 215 toward the center away from the supporting disk surface 203. After the steel pipe is inserted into the outer casing 209, release the feeding lever 213. Under the elastic force of the extrusion spring 217, the feeding transmission belt 215 contacts the surface of the steel pipe, and the axis of the steel pipe is driven to move by the feeding transmission belt 215). Then start the driving motor 117. The output shaft of the driving motor 117 drives the central gear 115 to rotate. The central gear 115 drives the outer ring gear 113 to rotate through the planetary gear 116. At this time, since the arc-shaped rack 120 has a movable space, the planetary gear 116 will also revolve when rotating, thereby driving the planetary gear plate 118 to rotate. The planetary gear plate 118 drives the linkage gear 1 19 rotates, the linkage gear 119 drives the arc rack 120 to rotate, the arc rack 120 drives the centering rotating ring 201 to rotate, and the centering rotating ring 201 will drive the centering linkage frame 206 to move along the axis of the centering guide slide bar 207 through the centering connecting rod 205, and then the centering roller 208 is driven to contact the surface of the steel pipe. When the centering roller 208 contacts the surface of the steel pipe, the centering roller 208 can no longer move, and the corrosion ring 102 can no longer move. The planetary gear 118 can no longer rotate, and the planetary gear 116 can no longer rotate. At this time, all the power will be transmitted to the outer ring gear 113, and the outer ring gear 113 will drive the input shaft of the gearbox 111 to rotate through the transmission belt 112, and the output shaft of the gearbox 111 will drive the rotating disk 110 inside the separation cylinder 109 to rotate, thereby driving the internal sodium chloride liquid to rotate.

[0029] Before cutting the steel pipe, first start the air pump 121, and the air pump 121 inflates the inside of the boosting ring 101, so that the pressure inside the boosting ring 101 increases (the specific pressure is adjusted by the pressure sensor and the regulating valve 122 inside the boosting ring 101 to ensure the contact area between the elastic film 103 and the surface of the steel pipe). The increase in the pressure inside the boosting ring 101 will push the elastic film 103 to deform, and the elastic film 103 will bulge when it is deformed, and then fit with the surface of the steel pipe, so that the gap between the two boosting rings 101 forms a sealed space, and at this time, start the liquid delivery pump 107, and the liquid The body delivery pump 107 delivers the sodium chloride liquid inside the separation cylinder 109 to between the two boost rings 101, and then passes through the steel pipe. Since the steel pipe is in an energized state, the steel pipe will be corroded, and the solids generated during the corrosion process will follow the flow, and then be discharged into the separation cylinder 109 through the discharge port 104. Since the sodium chloride liquid inside the separation cylinder 109 is in a rotating state, the solids will be thrown to the edge of the inner wall of the separation cylinder 109, and the liquid in the middle will be re-absorbed into the two boost rings 101 by the infusion pipe 106, and the steel pipe will be corroded repeatedly until the steel pipe breaks. This method can effectively reduce the noise generated during the cutting of steel pipes, and is preferably used to process steel pipes in crowded places to ensure that the hearing of construction workers will not be damaged.
