Abstract
The utility model discloses a steel hammer head used for crushing steel slag, which comprises a lock head and a hammer body connected with each other, wherein the hammer body comprises an upper end part and a lower end part which are connected detachably; an axial hole is arranged in the upper end part along the axis, and a threaded hole is arranged on the axis of the lower end part; one end of a double-head stud penetrates through the axial hole at the upper end part to be connected with a nut; the other end of the double-head stud is fixed in the threaded hole at the lower end part; and the lock head is fixed with the top of the upper end part. As for the steel hammer head, the upper end part and the lower end part connected detachably are adopted to form the hammer body, and the lower end part can be detached for independent replacement when being worn, so that the using cost is lowered.
Description
Technical field
The utility model relates to slag steel treatment facility, particularly a kind of stone steel hammer tup that is used for broken slag steel.
Background technology
The derivative that the slag steel is produced as metallurgical technology is but formed the back by the remaining iron and steel water-cooled after skimming, and iron-holder is higher, can return stove and heavily refine, and has considerable economic.Because the impurity that contains of slag steel is more, smelt to go to toward needing and process returning stove it, carry out fragmentation and remove the gred.Volume is big, impurity is many because the slag steel that produces in the metallurgical technology has, and can cause security risk and environmental pollution in the process, and adopts the broken processing technology of stone steel hammer just in time to solve an above-mentioned difficult problem.Stone steel hammer agent structure comprises sleeve, power drive mechanism, tup and U type suspender, and power drive mechanism, tup and U type suspender all are arranged on sleeve inner.Stone steel hammer action principle is: stone steel hammer sleeve is positioned over treats broken slag steel top, driven by power drive mechanism then and discharge after U type suspender is promoted to the sleeve top with tup, bump slag steel and make it broken when tup falls.
Existing stone steel hammer hammehead structure is a monoblock type hammehead structure, the I-shaped tapered end of upper end for being coupled with U type suspender, and middle-end is the cylindrical solid structure, the lower end is the cone entity structure, and middle-end and lower end fuse, and is on-dismountable.Some problems below this stone steel hammer hammehead structure exists in slag steel process: 1. because operation is frequent; The tapered end of stone steel hammer tup and the wearing and tearing of lower end cone structure are very fast; Have a strong impact on the operating efficiency and the quality of stone steel hammer, so the operating personnel has to tapered end and lower end cone are changed, because middle-end and lower end are on-dismountable; Need integral replacing during replacing, caused the higher use cost of stone steel hammer and the waste of material.2. because the inner no buffer structure of stone steel hammer tup in tup and slag steel knockout process, is prone to make tapered end and double-screw bolt to push mutually, makes the double-screw bolt deformation failure, and then shortened the service life of stone steel hammer tup.
The utility model content
The utility model problem to be solved provides a kind of stone steel hammer tup that is used for broken slag steel, overcomes the problems referred to above that exist in the prior art.
The utility model is used for the stone steel hammer tup of broken slag steel; Comprise continuous tapered end and hammer body, said hammer body comprises detachable upper end and the bottom that links to each other, and is provided with axis hole along axis in the upper end; The axis of bottom is provided with screwed hole; The axis hole that one end of studs passes the upper end links to each other with nut, and the studs other end is fixed in the screwed hole of bottom, and the top of said tapered end and upper end is fixed.
The said upper end of the utility model is a cylinder, and the bottom is a Rotary-table.
Axis hole in the said upper end of the utility model is three grades of stepped holes, is divided into higher level's axis hole, intergrade axis hole and subordinate axis hole from top to bottom successively, and said studs passes subordinate axis hole and fixes with the said nut that is placed in the intergrade axis hole.
The lower end of the said tapered end of the utility model is provided with a flange, and the flange of tapered end lower end places in the said intergrade axis hole, is provided with pressing plate in higher level's axis hole the flange of tapered end lower end is pressed in the intergrade axis hole, and pressing plate is fixed through bolt and said upper end.
Be provided with locking plate and beam between the flange of the said tapered end of the utility model lower end and said nut.
Also be connected a bearing pin between the said upper end of the utility model and the bottom.
Through above technical scheme, the stone steel hammer tup that is used for broken slag steel of the utility model adopts split type tup, and the upper end and the bottom of tup removably connect, and when the bottom centrum is worn and torn, can change the bottom separately, therefore provides cost savings; And in the upper end, between tapered end and nut that studs links to each other, beam is set, prevent that studs is out of shape in use.
Description of drawings
Fig. 1 the utility model stone steel hammer hammehead structure figure.
The said upper-end structure figure of Fig. 2.
The specific embodiment
As shown in Figure 1, the utility model is used for the stone steel hammer tup of broken slag steel, comprises continuous tapered end 1 and hammer body; Hammer body comprises detachable upper end that links to each other 8 and bottom 10; Be provided with axis hole along axis in the upper end 8, the axis of bottom is provided with screwed hole, and the axis hole that an end of a studs 7 passes the upper end links to each other with nut 6; The studs other end is fixed in the screwed hole of bottom, and tapered end 1 is fixed with the top of upper end 8.
As shown in Figure 2, the axis hole in the upper end is three grades of stepped holes, and the diameter that is divided into higher level's axis hole 11, intergrade axis hole 12 and 13, three grades of axis holes of subordinate's axis hole from top to bottom successively successively decreases from top to bottom successively.The bottom of tapered end 1 is provided with flange, and the flange of tapered end lower end places in the intermediate axis hole 12, is provided with pressing plate 2 in higher level's axis hole the flange of tapered end lower end is pressed in the intergrade axis hole, and pressing plate 2 is through the fixing (see figure 1) in bolt 3 and upper end.It is fixing with the nuts 6 that are placed in the intergrade axis hole 12 that studs 7 passes subordinate axis hole 13.Through the detachable connection in upper and lower end, dismounting and change easily after wearing and tearing are used in the bottom, and saved use cost.
As another embodiment of the utility model, the upper end of hammer body is a cylinder, and the bottom is a Rotary-table.And be provided with locking plate 4 and beam 5 at the flange of tapered end lower end and 6 on nut, prevent that studs is out of shape in use.
For preventing that upper and lower end from rotating in use, between upper end and bottom, be connected bearing pin 9, the two ends of bearing pin are plugged in respectively in the pin-and-hole 15 on upper end and the bottom.
