Abstract

The utility model discloses a device for removing oxide layers from a steel bar. Not more than two line bending wheels are arranged on a rack of the device and form a group of line bending wheels, wherein one of the line bending wheels is arranged on the upper part of the rack, and another line bending wheel is arranged on the lower part of the rack; a routing track of the steel bar is bent by the line bending wheels to form a bent line; directional wheels are arranged at the rear end of the line bending wheels; a steel wire brush is arranged at the rear end of the directional wheels; a grinding plate is arranged at the rear end of the steel wire brush; guide wheels are arranged at the rear end of the grinding plate; and a dust removal brush is arranged at the rear end of the guide wheels. In the process of removing the oxide layers from the steel bar, the steel bar is bent through the line bending wheels, most part of the oxide layers on the steel bar crack and drop from the surface of the steel bar, the oxide layers of which the surfaces are loosen are removed from the steel bar after the steel bar passes through the steel wire brush, the oxide layers which are tightly adhered are grinded and drop and burrs on the surface of the steel bar is grinded and becomes smooth when the steel bar passes through the grinding plate, and finally, dust which falls down from the surface of the steel bar through grinding is removed after the steel bar passes through the dust removal brush.

Description

Reinforcing bar oxide layer removal device

Technical field

The utility model belongs to the swell fixture technical field of processing equipment, relates to a kind of reinforcing bar oxide layer removal device.

Background technology

Swell fixture generally is made up of screw and expansion sleeve two parts, and expansion sleeve is enclosed within on the screw, and an end of screw is thicker, and other end machining screw is equipped with nut on screw thread.In the production of swell fixture, the raw material of production are mainly the reel reinforcing bar, and the reel reinforcing bar forms segment through after the punching press, and the one of which end is pressed slightly, and the other end is forced out screw thread.Be used to produce the reinforcing bar of swell fixture, there is layer of oxide layer on its surface, before being used to produce swell fixture, must carry out the deoxidation layer and handle; The traditional way of oxide layer is an acid wash on the removal reinforcing bar, and reinforcing bar is put into strong acid, after strong acid corrodes oxide layer reinforcing bar is put into clear water and cleans; The oxide layer of rebar surface is that this is eliminated totally; Adopt this processing method,, need the strong acid amount of use bigger because the oxide layer on the reinforcing bar has certain thickness; Not only cause production cost to increase, the strong acid that cleans after using also pollutes environment easily.

Summary of the invention

The utility model adopts strong acid to remove the production method of rebar surface oxide layer in the prior art, and the strong acid amount that existence is used is big, production cost is high; The problem that easily environment is polluted, a kind of reinforcing bar oxide layer removal device is equipped with one group of broken line wheel on the frame of this device; The broken line wheel is no less than two, and one of them is installed in the top, and another is installed thereunder; The broken line wheel is bent into a broken line with the track of reinforcing bar, in broken line wheel rear end directional wheel is installed, and the directional wheel rear end is equipped with wire brush; The wire brush rear end is equipped with the frosted dish, and the frosted back-end disk is installed directive wheel, and clean ash brush is installed in the directive wheel rear end.

Adopt technique scheme, when the oxide layer on carrying out reinforcing bar is removed, reinforcing bar is passed through this device; With the wheel of the broken line on this device reinforcing bar is bent processing, the oxide layer major part during bending on the reinforcing bar is burst apart from rebar surface and is come off, and reinforcing bar is behind the process wire brush; The loosening oxide layer in surface is brushed; When passing through the frosted dish again, some adhere to tighter oxide layer and are come off by friction, and the hair defect of rebar surface is polished cunning simultaneously; When the clean ash of the last process of reinforcing bar was brushed, the dust under grind on its surface was by outwash.So far, the oxide layer of rebar surface is polished totally.
