Description
Technical field
This utility model relates to the auxiliary mould during aluminum alloy melt casting, is specifically related to a kind of head piece cleaning hammer drill.
Background technology
During aluminum alloy melt casting, the aluminum slag at head piece needs to clean out.Otherwise the aluminum slag at head piece is accumulated for a long time, causes head piece to taper into, and affects the processing speed of aluminum liquid and being difficult in subsequent use and opens head piece or more difficult block head piece.Now it is frequently necessary to open head piece by violence, there is potential safety hazard and had a strong impact on the service life of head piece brick.So the aluminum slag at head piece is cleaned out the most necessary.In prior art, usual iron clears up head piece, and the tip relying primarily on iron is cleared up, and finds, owing to the action of points area of iron is less, it is impossible to cleaned out by the aluminum slag at head piece, and clearance time is longer during use.
Summary of the invention
The purpose of this utility model is to propose a kind of head piece cleaning hammer drill, and the aluminum slag at head piece can thoroughly be cleaned out by this hammer drill, and cleaning efficiency is high, easy to use；It is avoided that simultaneously and head piece brick is caused damage.
A kind of head piece cleaning hammer drill described in the utility model, including a straight-bar and a sleeve, the rear portion of described straight-bar is threaded rod, and the front portion of described straight-bar is prism, and the front end of described straight-bar is provided with circular cone, and the tip of described circular cone is arranged forward；Described sleeve is provided with screwed hole that is coaxial with described sleeve and that run through described sleeve, described sleeve is assemblied on described threaded rod by described screwed hole, the rear portion of described sleeve is provided with two handles in doorframe shape, and two described handles are oppositely arranged centered by the centrage of described sleeve；nullThe steel plate of at least two pieces of rectangular triangles it is uniformly distributed circumferentially on the outer wall of the front end of described straight-bar，Described edges of plate has two right angle sidewalls corresponding with the right-angle side of right angled triangle、One oblique sidewall corresponding with the hypotenuse of right angled triangle，One described right angle sidewall is welded on the outer wall of described straight-bar and this right angle sidewall is arranged along the longitudinal direction，Described oblique sidewall moves closer to described straight-bar from rear to front，The edge of the bottom surface of the anterior and described circular cone of described oblique sidewall is connected，Several breach running through described steel plate along the direction being perpendicular to described steel plate it are evenly distributed with on described oblique sidewall，Angle between two sidewalls and the described oblique sidewall of described breach is acute angle，The scraper part of two wedge shapes is formed with the opening part at described breach，A described scraper part in two described scraper parts is forward，Another described scraper part is backwards.
Further, described sleeve is hollow prism.
This utility model is provided with sleeve and threaded rod, can adjust two distances between handle and circular cone by turnbarrel, can adjust head piece cleaning hammer drill for different work requirements；The front portion of straight-bar is prism simultaneously, and sleeve is hollow prism, and during turnbarrel, operator one only holds the front portion of straight-bar, and another holds sleeve, just can turnbarrel the most easily, easy to operate；Owing to sleeve is provided with two handles in doorframe shape, and two handles are oppositely arranged centered by the centrage of sleeve, head piece cleaning hammer drill probability of landing from operator's hands can be reduced while conveniently taking, and when needing bigger power or needing to clear up head piece by rotation, operator's both hands can hold a handle respectively, easy to operate and laborsaving；The tip of circular cone can be used to bore or tap more obstinate aluminum slag so that clears up more thorough；Steel plate is used for increasing cleaning scope, promotes cleaning efficiency, and the scraper part on steel plate can also be used to clear up more obstinate aluminum slag simultaneously, it is possible to increase cleaning scope, lifting cleaning efficiency and the damage to head piece brick further less；Owing to the edge of a knife of scraper part is at an acute angle, and two scraper parts on a breach point to contrary, further enhancing cleaning effect.Therefore this utility model has advantage easy to adjust, easy to use, that cleaning efficiency is high, cleaning scope is big, cleaning effect is good, and can alleviate the damage to head piece brick.
