Abstract
The invention relates to a combined roll shaft of a roller press. The combined roll shaft of the roller press comprises a roll shaft base body and a plurality of pressing modules, wherein the shape of the cross section of the roll shaft base body is a regular polygon; the plurality of pressing modules are located at the periphery of the roll shaft base body, are respectively connected with the roll shaft base body, and are pieced together to form a cylindrical roll surface. The combined roll shaft of the roller press, which is provided by the invention, is convenient to assemble and disassemble, can greatly prolong the service life of the roller press, and reduces the difficulty of maintenance.
Description
technical field:
The present invention relates to for mineral are carried out to broken roll squeezer, particularly be a kind of roll squeezer combined type roll shaft.
background technology:
?roll squeezer is the energy-conservation milling equipment of the industries such as a kind of new and effective mine, cement, and it is to rotate in opposite directions material is carried out to the high pressure pulverizing by two roll shafts of driven by motor.The roll squeezer crushing efficiency is very high, the equipment such as the ball mill that all or part of alternative energy consumption of energy is high and ore deposit mill.
Roll squeezer carries out attrition crushing by the roll surface pair roller of two roll shafts to material, so its operating efficiency is higher, but roll squeezer also is subject to the restriction of himself defect, is mainly that the roll surface wear-resisting layer of roll shaft in roll squeezer can't reach more satisfactory result of use.At present wearing layer is to adopt the build-up wear-resistant material, is characterized in that workload is large, involve great expense, easy to wear, service life is short, and wearing layer in use easily polishes, and becomes more smooth, can't effectively snap in material, causes its production efficiency to descend.The roll surface maintenance difficulties is greatly also one of its major defect in addition, when roll surface wearing to a certain extent after, whole roll shaft need to be disassembled, be transported to specialized factory and safeguarded, the expense of its generation is large, the transhipment time is long, affects its normal production.Therefore improve the surface structure of roll shaft, improving the service life of roll squeezer and reducing maintenance difficulties is current roll squeezer technical barrier anxious to be resolved.
summary of the invention:
The objective of the invention is in order to overcome the deficiency of above-mentioned technology, a kind of dress be provided, tear open conveniently, the service life that can greatly improve roll squeezer, reduce maintenance difficulties for the combined type roll shaft on roll squeezer.
The object of the present invention is achieved like this:
Combined type roll shaft of the present invention, comprise roll shaft matrix that cross sectional shape is regular polygon, be positioned at and be connected and be assembled into respectively some die blocks of cylindrical roll surface with the roll shaft matrix on roll shaft matrix periphery.
Every above-mentioned die block is connected with the roll shaft matrix by hexagon socket head cap screw.
Straight pin with hexagon socket head cap screw hole interference fit is housed in the hexagon socket head cap screw hole on above-mentioned die block; straight pin is not damaged for the protection of hexagon socket head cap screw; in order to be convenient to hexagon socket head cap screw is dismantled when changing die block; straight pin is connected by interference fit with die block, in order to avoid it in use comes off.
On above-mentioned every die block and roll shaft matrix phase correspondence position, keyway is arranged, key is contained in die block with in the corresponding keyway of roll shaft matrix phase.
Cylindrical stud hole is arranged at above-mentioned die block top, hard alloy stud with the cylindrical pillars Bolt-hole fits is housed in cylindrical stud hole, cylindrical stud hole on the die block top is processed by the mode of machining, guarantees size, tolerance and the surface smoothness in cylindrical stud hole; The hard alloy stud material is hard alloy steel, guarantee that the performances such as its hardness, bending strength reach instructions for use, the hard alloy steel stud requires to guarantee its corresponding fillet or chamfering, and its cylindrical guarantees its size, tolerance and surface smoothness by the mode of refining.Before hard alloy stud is pressed into to die block, first be coated with the solid special glue of outsourcing, it be fastened on die block, in order to avoid it comes off in the course of the work.
Above-mentioned hard alloy stud exposes die block end face 3～5mm.
Combined type roll shaft of the present invention is contained on roll squeezer, and in use for some time, die block will there will be the situation of wearing and tearing to roll squeezer.After die block may wear to a certain degree, must change die block.Concrete operations are that straight pin is taken out, then, by the hexagon socket head cap screw dismounting, change die block, newer die block is installed in the same way.
The present invention fills, tears open conveniently, in the service life of greatly improving roll squeezer for the roll-in function, reduces the roll squeezer maintenance difficulties.
the accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
The A that Fig. 2 is Fig. 1 is to view.
The I section enlarged drawing that Fig. 3 is Fig. 1.
The II section enlarged drawing that Fig. 4 is Fig. 2.
The top view that Fig. 5 is Fig. 4.
the specific embodiment:
Referring to Fig. 1～Fig. 3, the present embodiment combined type roll shaft, comprise the roll shaft matrix 1 that cross sectional shape is regular polygon, is positioned to be connected and to be spliced into respectively the some die blocks 3 of cylindrical roll surface with the roll shaft matrix on roll shaft matrix periphery.
Referring to Fig. 1～Fig. 4, every die block 3 is connected with roll shaft matrix 1 by hexagon socket head cap screw 2.On die block and roll shaft matrix phase correspondence position, keyway is arranged respectively, key 6 is contained in die block with in the corresponding keyway of roll shaft matrix phase.
Referring to Fig. 3～Fig. 5; straight pin 5 with hexagon socket head cap screw hole interference fit is housed in the hexagon socket head cap screw hole 8 on die block 3; straight pin is not damaged for the protection of hexagon socket head cap screw; in order to be convenient to hexagon socket head cap screw is dismantled when changing die block; straight pin is connected by interference fit with die block, in order to avoid it in use comes off.
Referring to Fig. 3～Fig. 5, cylindrical stud hole 7 is arranged on die block 3 tops, the hard alloy stud 4 with the cylindrical pillars Bolt-hole fits is housed in cylindrical stud hole.Cylindrical stud hole 7 on die block 3 tops is processed by the mode of machining, guarantees size, tolerance and the surface smoothness in cylindrical stud hole; Hard alloy stud 4 materials are hard alloy steel, guarantee that the performances such as its hardness, bending strength reach instructions for use, the hard alloy steel stud requires to guarantee its corresponding fillet or chamfering, and its cylindrical guarantees its size, tolerance and surface smoothness by the mode of refining.Before hard alloy stud is pressed into to die block, first be coated with solid special glue, it be fastened on die block, in order to avoid it comes off in the course of the work.Hard alloy stud 4 exposes die block end face 3～5mm.
Above-described embodiment is that foregoing of the present invention is further described, but this should be interpreted as to the scope of the above-mentioned theme of the present invention only limits to above-described embodiment.All technology realized based on foregoing all belong to scope of the present invention.
