Abstract
A device for adding large die casting plate blank protecting slag relates to the field of cast steel die casting technology in the metallurgy industry, in particular to a device for adding the protecting slag in molten steel protection casting and with high quality requirement, and mainly comprises two protecting slag adding grooves with bin doors and a group of winding drum shafts controlling the lifting height of the protecting slag adding grooves and the opening degree of the bin doors. A slide stopping clamp, a slide stopping flywheel and a steel wire rope groove and a steel wire rope deflection preventing device are arranged on each winding drum shaft. The winding drum shafts are placed on a mould cavity upper opening through supports and support seats. Two bin doors are connected to the winding drum shafts controlling the lifting height through four connecting steel wire ropes, and the two protecting slag adding grooves with the bin doors are connected to the winding drum shafts controlling the opening degree of the bin doors through two connecting steel wire ropes. The device for adding the large die casting plate blank protecting slag can evenly add protecting slag in a long-distance mode, namely achieves the purpose of protecting molten steel evenly and avoids slag entrapment caused by too much adding amount in one time, the produced plate blank surfaces are smooth and free of entrapped slag, and no dust is generated in adding.
Description
Technical field
The utility model belongs to metallurgy industry cast steel die casting technical field, is specifically related to the medium-and-large-sized die casting slab covering slag adding apparatus of a kind of high-quality requirement molten steel protection cast.
Background technology
The production of present large-scale die casting slab is because slab is thinner, highly higher relatively; Surpass more than 5 meters apart from place, cap oral cavity at the bottom of the normal condition counterdie, wide heat radiation comparatively fast do not used the covering slag cast in the casting process; Surface quality is relatively poor, and later stage cleaning difficulty is big, also is prone to produce waste product.But be to use covering slag owing to far away at the bottom of mould, the artificial difficulty and inhomogeneous that adds is hung the wayward also easy volume slag defective that produces of addition of adding.
Summary of the invention
The purpose of the utility model is in order to overcome above shortcoming, and the medium-and-large-sized die casting slab covering slag adding apparatus of a kind of molten steel protection cast that proposes.
The utility model is realized through following technical scheme: large-scale die casting slab covering slag adding apparatus, mainly comprise bearing and support, and it is characterized in that the top of support is provided with one group of spool shaft, spool shaft is provided with steel wire rope groove; Be provided with two covering slags that have door below the support and add groove; The control covering slag adds the groove lifting height and links to each other with spool shaft respectively through the steel wire rope groove on the spool shaft with the steel wire rope that the control covering slag adds groove door open degree.
Usually, the spool shaft of the utility model device is provided with handle, on-slip card and on-slip flywheel; Steel wire rope groove on the spool shaft is provided with the device that prevents the steel wire rope sideslip.
It is suitable for reading that the device of the utility model is placed on die cavity.
In the utility model device; Two covering slags adding grooves are connected on the spool shaft of control lifting height through four connection steel wire ropes of controlling covering slags adding groove lifting heights, and two covering slag adding grooves that have door are connected on the spool shaft of controlling the door open degree through two connection steel wire ropes of controlling covering slags adding groove door open degree.
During application, the covering slag adding groove that the two winding drum axle that turns clockwise simultaneously lifting door has door rises overally; Open spool shaft through the rotation door and promote covering slag adding groove,, control the door open degree through the control difference in height because gravity effect door is opened automatically.
The utility model device can realize that the distance protection slag evenly adds, and promptly reaches the purpose of even protection molten steel, avoids disposable addition too much to cause volume slag generation of defects again.
Description of drawings:
Accompanying drawing 1 is the large-scale die casting slab of a utility model embodiment covering slag adding apparatus sketch map.
Among the figure, the 1-support; The 2-bearing; The covering slag that 3-has door adds groove; The connection steel wire rope of 4-control lifting height; The 5-handle; The steel wire rope groove of 6-control door open degree; The steel wire rope groove of 7-control lifting height; The spool shaft of 8-control door open degree; The spool shaft of 9-control lifting height; 10-on-slip flywheel; 11-on-slip card; The connection steel wire rope of 12-control door open degree.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
Embodiment: present embodiment is shown in accompanying drawing 1; Mainly comprise the bracing or strutting arrangement that constitutes by bearing 2 and support 1; It is suitable for reading to be arranged at die cavity, and its main feature is that the top of support 2 is provided with one group of spool shaft, promptly controls the spool shaft 8 of door open degree, the spool shaft 9 of control lifting height; Be respectively equipped with steel wire rope groove on two spool shaft, promptly control the steel wire rope groove 6 of door open degree, the steel wire rope groove 7 of control lifting height; Be provided with two covering slags that have door below the support 2 and add groove 3; The connection steel wire rope 4 of four control lifting heights links to each other with spool shaft 8,9 respectively through the steel wire rope groove 6,7 on the spool shaft with the steel wire rope 12 that is connected of two control door open degree; Be respectively equipped with handle 5, on-slip flywheel 10 and on-slip card 11 on the spool shaft 8,9; Steel wire rope groove 6,7 on the spool shaft is provided with the device that prevents the steel wire rope sideslip.
In the present embodiment; The door that has the covering slag adding groove 3 of door is split on the middle steel wire rope groove 7 that is connected through the connection steel wire rope 4 of controlling lifting height on the spool shaft 9 of controlling lifting height, and the covering slag that has door adds groove 3 and is connected through the connection steel wire rope 12 of controlling the door open degree on the steel wire rope groove 6 on the spool shaft 8 of controlling the door open degree.
The utility model device is when producing the large cast steel slab; Put down the covering slag that has door according to the die cavity height and add certain distance at the bottom of groove 3 to the mould; The connection steel wire rope 4 of retentive control lifting height and control door open degree be connected steel wire rope 12 evenly stressed and door be in closed condition, on-slip card 11 is stuck in to keep certain height on the on-slip flywheel 10 and does not slide.
When waiting to need to add covering slag; The spool shaft 9 of retentive control lifting height is motionless; With the spool shaft 8 of handle 5 Spin Control door open degree, utilize gravity effect door to open automatically, the spool shaft 8 that rotates back and forth control door open degree can realize the size of door open degree.
In the time of need promoting with the molten steel rising; Add slag chute and rise overally with turn clockwise covering slag that the spool shaft 9 of control lifting height has a door of handle 5, the spool shaft 8 of Spin Control door open degree is tightened up the connection steel wire rope 12 of controlling the door open degree in proportion subsequently.
The present embodiment device can realize that the distance protection slag evenly adds, and promptly reaches the purpose of even protection molten steel, avoids disposable addition too much to cause volume slag generation of defects again, and the smooth nothing volume of the steel slab surface of producing slag adds and fashionablely can not produce dust.
