Description
Technical field
The utility model relates to a kind of device of removing the metallic rod surface oxide layer, relates in particular to a kind of aluminum-like rod surface scraping mechanism, and the utility model also can be used for the processing of metallic rod surface oxide layers such as copper bar, iron.
Background technology
Known metallic rod dish circle is removed surface oxide layer several ways: 1, peeling mode: have certain peeling and cutting cone angle, positioning and guiding is passed through at two ends at peeling mode, under the traction of front end power, to metallic rod surface peeling, the metallic rod surface is in pure state after the peeling continuously.Need very big tractive force when this method weak point is peeling, and tractive force is subjected to the restriction of production technology.2, mechanical cleaning technology: this method was drawn metallic rod earlier and is dialled the oil film that the surface is removed in the back before scrubbing, and by dipping by lye, water cleans, and drying is scrubbed with wire brush again.This method weak point is: the wire brush wearing and tearing are very fast, the failure rate of machinery height, scrub in the process, fricative heat can cause the metallic rod surface to form oxide layer again between metallic rod and brush, friction simultaneously produces the Electrostatic Absorption dust, and mechanical noise is big, and the metallic rod surface quality after scrubbing is had a significant impact.Above-mentioned two kinds of methods can't satisfy the specification requirement of present stage metallic rod dish circle removal surface oxide layer.
Summary of the invention
The purpose of this utility model is to provide a kind of aluminum-like rod surface scraping mechanism, helps simplifying the aluminium rod surface treatment process by the utility model, improves and the original metal structure state of maintenance aluminium bar, helps to improve lumber recovery and reduces production costs.
The technical scheme that realizes the utility model purpose is as follows:
Aluminum-like rod surface scraping mechanism, pedestal is provided with the main shaft that is used to locate the aluminium bar, main shaft is axially locked on the pedestal, main shaft is provided with the locating hole that passes for the aluminium bar, described main shaft is provided with the scraping dish that relative main shaft can rotate in a circumferential direction, the axial end of this scraping dish is provided with cavity, the fixedly connected cover plate of the accent of cavity, be evenly equipped with a plurality of Roll centering device for scraping that act on aluminium rod surface on the cover plate, be evenly equipped with the governor weight device of a plurality of cooperation Roll centering device for scraping in the described cavity, one end of each Roll centering device for scraping extend in the described cavity and circumferentially is connected with a governor weight device, described main shaft one end pass its end behind the centre bore that is provided with on the cover plate be positioned at the Roll centering device for scraping other end near.
Adopted such scheme, described main shaft is provided with the scraping dish that relative main shaft can rotate in a circumferential direction, and in the course of the work, the scraping dish rotates and main shaft does not rotate.Be evenly equipped with a plurality of Roll centering device for scraping that act on aluminium rod surface on the cover plate, by the rolling bearing in the Roll centering device for scraping, not only can carry out roll extrusion to processed aluminium rod surface, and in roll extrusion, processed aluminium bar has been formed clamping, the therefore accurate centralized positioning that the aluminium bar is formed.In addition, these self-centering rolling bearings around aluminium rod surface revolution and rotation the time, to coil circle originally draws outside the sea surface oil slick that (draws the operation of dialling to before the scraping) when dialling is squeezed in, do not taken out of, a spot of oil film is arranged simultaneously after the rolling bearing roll extrusion, aluminium rod surface has obtained higher fineness and circularity, and this is the prerequisite condition of high-precision surface scraping, through helping making scrape depth to be controlled between the 0.02mm-0.03mm after the roll extrusion of roll extrusion bearing.Straight crooked or be under the situation of swing when the aluminium bar, rolling bearing is in free state locking aluminium rod surface, and with the nonstraightness of aluminium bar, swing and changing, therefore scrape sharpener and may follow rolling bearing aluminium bar external diameter is done the even scraping of circumference, help improving the scraping precision.Be evenly equipped with the governor weight device of a plurality of cooperation Roll centering device for scraping in the cavity, one end of each Roll centering device for scraping extend in the described cavity and circumferentially is connected with a governor weight device, described main shaft one end pass its end behind the centre bore that is provided with on the cover plate be positioned at the Roll centering device for scraping other end near.The governor weight device is mainly used in the position of control Roll centering device for scraping, when mechanism works, the scraping dish produces at a high speed, and rotation is rotated the governor weight device synchronously, but because gravity block one end of governor weight device is a free end, therefore, self can rotate under the effect under the centrifugal force that high rotating speed forms, gravity block rotates, then can drive the Roll centering device for scraping that circumferentially connects with it rotates, the Roll centering device for scraping rotates then can arrive the operating position that it is processed the aluminium bar, thereby the aluminium bar is carried out above-mentioned automatic process operation.And the rotation of gravity block is restricted property, because gravity block is in rotation process, it can compress connected elastic device, elastic device imposes opposition to gravity block, therefore gravity block can only turn an angle promptly restricted, and this angle is also passed through a series of calculating just, makes the Roll centering device for scraping turn to the angle of its operating position.When mechanism quit work, gravity block resetted under the reaction force of elastic device, like this, the Roll centering device for scraping was back into initial position.
In sum, at first, the weightless Changing Pattern of the utility model utilization also organically combines with frame for movement, is converted into and solves the specification requirement that metallic rod dish circle is removed the surface oxide layer problem.Secondly, the utility model has realized that scrape depth controls automatically, feed and withdrawing are controlled automatically, the sur-face peeling layer is discharged to outside the mechanism by discharging opening with the natural wind that the scraping dish produces in the scraping process, therefore, by these natural winds the aluminium bar is had the cooling effect of carrying out, aluminium rod surface does not have variations in temperature after the scraping, does not have the surface oxidation again that makes processing because of temperature problem.The utility model has been realized the continuous profiling scraping of aluminium rod surface, compare with the old technology of tradition, good, the no dust of aluminium rod surface fineness, noiseless, freedom from repairs, can remove preliminary treatment in the prior art from, stablizing on the aluminium rod surface quality base, improved operating efficiency,, also greatly reduced production cost simultaneously for follow-up reliably guaranteed at production " copper-clad aluminum conductor " mass of foundation.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
