Description
The utility model belongs to the hoop-driving process equipment of fire resistive material product, is applicable to the cuff of making the required usefulness of fire resistive material product outer rim.
Some fire resistive material product, the sliding plate brick used of ladle bleed-out for example, when entering duty, environment temperature often moment rise to more than 1000 ℃ by room temperature, its surface is easy to generate crackle and causes the disconnected broken of sliding plate brick because of further expanding of crackle.For generation, the expansion that prevents crackle, improve the service life of sliding plate brick, the common practice is to play the stirrup (steel band) of an annular on the sliding plate brick outer perimeter.The steel band of lock ring on the sliding plate brick outer perimeter when moment enters the hot operation state by room temperature, can limit the generation and the expansion of sliding plate brick face crack effectively, prolongs the service life of sliding plate brick.So tightening garter spring shape steel band in the outer perimeter of some fire resistive material products is the effective way that prolongs its service life.
At present, the hoop-driving of fire resistive material product is the chuck by a low speed rotation, and rotating shaft that steel band coils and the damping unit that makes steel band have certain tensioning are installed, and one can the transient heating steel band electric heater.The course of work is: fire resistive material product, it for example is the above-mentioned sliding plate brick of speaking of, operating personnel are taking the lead to be attached on the outer perimeter of sliding plate brick and be installed on them on the chuck together steel band at first, then, starter motor drives the chuck low speed rotation, and the steel band with certain tensioning just is wrapped on the outer perimeter of sliding plate brick.Before steel band is wound, by about electric heater transient heating to 800 ℃.When the outer rim of sliding plate brick was wound three circles with the low speed rotation of chuck, outage was shut down, and manual operations is cut off steel band and fracture is welded on and forms annular stirrup on the steel band.To be cooled to room temperature, stirrup shrinks lock ring on the outer rim of sliding plate brick.The deficiency that this wound form hoop-driving machine exists is: 1) clamping force of steel band is little.During winding, because what thickness of strips and it were produced is directly proportional to the sliding plate brick applied pressure, the intensity of sliding plate brick self is limited, for not making sliding plate brick by the applied pressure crushing of steel band institute, and satisfy technological requirement,, generally can only select for use thickness at the steel band below 1 millimeter so the thickness of steel band is restricted, the clamping force of steel band is little, is difficult to satisfy the demand of sliding plate brick to clamping force.2) steel band is uneven to the clamping force control of sliding plate brick.Because the temperature of transient heating steel is restive evenly, so manually Han Jie steel band is uneven to the clamping force control of sliding plate brick.
The purpose of this utility model is a kind of hydraulic pressure cuff machine that is used for fire resistive material product that designs at the deficiency of above-mentioned wound form hoop-driving machine existence.It can select the thick band of suitable steel band in advance according to operating mode and actual demand, come to satisfy to resemble fire resistive material product that this class of sliding plate brick needs hoop-driving and the demand of clamping force is not made be damaged.Stirrup is to be welded into garden annular automatic sizing on the cuff machine through giving first blanking, is enclosed within on the outer perimeter of sliding plate brick after again it being heated to uniform temperature.Because the steel band of stirrup can give earlier accurately blanking and on the cuff machine accurate automatic sizing, so steel band is easier to control evenly to the clamping force ratio of sliding plate brick.
