DETAILED DESCRIPTION
[0012] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0013] like Figure 1 As shown, in this embodiment, a device for drying and removing black skin for steel pipe threads includes a base 1, on which a support 4 is movably provided, and the support 4 can move longitudinally along the base 1. A swing arm 7 is hinged on the support 4, and a grinding device 9 is provided at one end of the swing arm 7. Two oppositely arranged rotating wheels 8 are provided above the grinding device 9. The two rotating wheels 8 form a rotating pair of wheels, and the distance between the two rotating wheels is greater than the size of the grinding device. The steel pipe is provided on the rotating pair of wheels, and the rotating pair of wheels drives the steel pipe to rotate. A counterweight 6 is provided at the other end of the swing arm 7. Under the action of the counterweight 6, the swing arm 7 rotates around the hinge point, driving the grinding wheel on the grinding device 9 to be tangent to and fit the threaded part of the steel pipe, and the grinding wheel grinds the threaded part of the steel pipe. A connecting plate 10 is provided on the central sleeve of the grinding device, and a drying unit is provided on the connecting plate 10. The outlet of the drying unit faces the steel pipe to dry the coolant remaining on the threaded part of the steel pipe. A vertically arranged swing arm drive cylinder 5 is provided on the support 4, and the extended end of the swing arm drive cylinder 5 is connected to the swing arm 7, and the swing arm drive cylinder 5 is close to the side of the counterweight 6. The swing arm drive cylinder 5 drives the swing arm to rotate around the hinge point, driving the grinding device and the drying unit to approach or move away from the steel pipe.
[0014] Two longitudinally parallel guide rails 2 are mounted on the base 1. Two full-length sliders 3 are mounted on the bottom of the support 4. These sliders 3 correspond to and engage with the corresponding guide rails 2. A longitudinally movable cylinder 14 drives the support 4 along the guide rails 2, driving the swing arm, grinding device, and drying unit longitudinally along the steel pipe. The longitudinally movable grinding device polishes all the black skin on the threads, while the longitudinally movable drying unit dries any remaining coolant on the threads.
[0015] The drying unit includes a drying support frame 11, which is fixed on the connecting plate 10. A dryer 12 is fixed on the drying support frame 11. The outlet of the dryer 12 is connected to an air nozzle 13, which faces the steel pipe.
[0016] The above-mentioned grinding device is a black leather grinding machine.
[0017] The rotation of the swing arm drives the grinding device and dryer to swing together. The dryer and nozzle can also move synchronously with the longitudinal movement of the grinding device. As the steel pipe rotates and moves longitudinally, the grinding device and dryer complete the grinding and drying of the black scale on the thread at the end of the steel pipe. This application has a simple structure, saves time and effort, and can remove both residual coolant and black scale on the thread, thereby improving the quality of the steel pipe.
[0018] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
