In the actual processing process, the fact that the surface of the pipe has more rust is easily found, the rust increases the wall thickness of the pipe, the influence of the rust on the cold rolling process is not considered in the process of cold rolling the dried vegetable, the size of the cold-rolled pipe is not consistent with the required size, and the quality of the pipe is influenced.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a rust removing device of a cold rolling mill, which achieves the effects of conveniently and quickly removing rust and improving the cold rolling quality of a pipe through a rust removing ring.
In order to achieve the purpose, the invention provides the following technical scheme:
a rust removing device of a cold rolling mill comprises a shell and a primary rust removing assembly arranged at the feeding end of the shell, wherein the primary rust removing assembly comprises a base arranged on the ground and a grinding cylinder rotatably connected to the inside of the base;
the base is provided with a through hole, and the grinding cylinder is rotatably connected in the through hole;
one end of the sand grinding cylinder is provided with a derusting ring, and the inner diameter of the derusting ring is the same as the outer diameter of the pipe;
a spiral feeding plate is fixedly connected to the inner circumferential surface of the sand grinding cylinder;
the machine base is also internally provided with a driving component which can drive the sanding cylinder to rotate.
By adopting the technical scheme, the surface of the pipe generates rust due to the influence of wind, wind and sunlight after the pipe is exposed for a long time, so that the wall thickness of the pipe is changed, and when the pipe is subjected to cold rolling, the size of the cold-rolled pipe is not in accordance with the requirement due to the influence of the rust on the wall thickness of the pipe, so that the quality of the pipe is influenced; the grinding cylinder can rotate, so that the derusting ring rotates along the direction vertical to the axial direction of the pipe, the derusting ring can grind off rust on the outer wall of the pipe, the rust on the outer wall of the pipe is reduced, the influence of excessive rust on the cold rolling of the pipe is prevented, and the cold rolling precision of the pipe is improved; the spiral feeding plate in the grinding cylinder plays a role in feeding in the rotating process of the grinding cylinder, can convey away rust ground by the rust removing ring, prevents the rust from remaining in the grinding cylinder, and influences the rust removing effect after the time process.
The invention is further configured to: the outer circumferential surface of the sand grinding cylinder is fixedly connected with two rotating rings, and the rotating rings are arranged at two ends of the sand grinding cylinder;
two annular sliding grooves corresponding to the rotating rings are formed in the inner wall of the through hole, and the rotating rings can rotate in the sliding grooves.
Through adopting above-mentioned technical scheme, dull polish section of thick bamboo is at the pivoted in-process, because there is frictional force between circle and the tubular product of removing rust, so dull polish section of thick bamboo can produce the trend along dull polish section of thick bamboo axis direction motion, lead to dull polish section of thick bamboo to break away from the through-hole even, cause dull polish section of thick bamboo can not normal use, the swivel becket is in the spout, and the swivel becket only can rotate round the centre of a circle of ring in the spout, no matter how rotate the dull polish section of thick bamboo, because the cooperation of swivel becket and spout, so dull polish section of thick bamboo can not break away from with the through-hole, so can prevent that dull polish section of thick.
The invention is further configured to: the through hole is close to the casing one end and is seted up the mounting groove that communicates with each other with the spout, and the rust cleaning circle is in the mounting groove, and has seted up a plurality of mounting holes on the surface of rust cleaning circle, and the grafting has the bolt in the mounting hole, and the lower extreme and the rotating ring threaded connection of bolt.
By adopting the technical scheme, the derusting ring is directly contacted with the surface of the pipe to derust the pipe, and the derusting process depends on the friction between the derusting ring and the pipe, so the loss of the derusting ring is more serious, and the derusting ring needs to be replaced regularly; the rust removing ring is bolted together through the bolt and the grinding cylinder, and only the bolt needs to be replaced and unscrewed when the rust removing ring needs to be replaced, so that the rust removing ring can be quickly replaced, the replacement efficiency is improved, and the bolt is bolted to ensure that the rust removing ring can be stably fixed on the grinding cylinder.
The invention is further configured to: the inner circumferential surface of the derusting ring is fixedly connected with a plurality of strip-shaped bulges, and the length direction of the bulges is the same as the axial direction of the derusting ring.
Through adopting above-mentioned technical scheme, the contact area of rust cleaning circle and tubular product has been reduced to the arch of rectangular shape, under the unchangeable circumstances of pressure, the contact force between rust cleaning circle and the tubular product has been increased, make the rust cleaning circle can be better to the rust cleaning of tubular product, and bellied length direction is the same with the axis direction of rust cleaning circle, then the rotation of grinding a sand section of thick bamboo can drive the arch and rotate along the direction with tubular product axis direction vertically on the periphery of tubular product, make the arch can be better clear up the iron rust on the tubular product surface.
The invention is further configured to: the end part of the protrusion far away from the inner wall of the derusting ring is provided with an arc-shaped groove which can be attached to the surface of the pipe.
By adopting the technical scheme, because the outer surface of the pipe is a curved surface, the protrusions and the surface of the pipe are in line contact, so that the protrusions cannot well remove rust, the effect of removing the rust is influenced, and the quality of the cold-rolled pipe is further influenced; the arc-shaped groove can be attached to the surface of the pipe, the protrusions can rub the surface of the pipe along with the rotation of the grinding cylinder, rust on the surface of the pipe is ground off, the influence of the rust is reduced, and the quality of a cold-rolled product is improved.
The invention is further configured to: the secondary rust removal assembly capable of machining the pipe again is arranged at the discharge end of the primary rust removal assembly, the structure of the secondary rust removal assembly is basically the same as that of the primary rust removal assembly, and only the rust removal ring of the secondary rust removal assembly is higher in precision than that of the primary rust removal assembly.
By adopting the technical scheme, the primary rust removing component primarily removes the rust on the pipe, and the secondary rust removing component further removes the rust on the pipe, so that the rust can be removed more thoroughly, the rust on the pipe is further reduced, and the cold rolling quality of the pipe is improved; the workpiece is subjected to rust removal through the primary rust removing assembly and the secondary rust removing assembly, and rust removal is performed in two steps, so that abrasion of a rust removing ring can be reduced, and the service lives of the primary rust removing assembly and the secondary rust removing assembly are prolonged.
