Description

2PCF-2022 single segment hammer type crusher rotor

Technical field

The utility model relates to mine mechanism, is specifically related to a kind of 2PCF-2022 single segment hammer type crusher rotor.

Background technology

2PCF-2022 single block hammer crusher is mainly used in large-scale cement production line, and be a kind of impact breaker, main tup carries out strong strike to ore in epicoele, and ore makes ore reduction to the collision between the shock of anvil and ore.2PCF-2022 single block hammer crusher primary structure is made up of rotor, anvil, discharge grate, housing, shaft withdrawing device and the driving section parts that grade.Rotor is the core of disintegrating machine, it by hammering dish into shape, end plate, tup, main shaft, large belt wheel, bearing and bearing block form.Because the increase that could not fully take into account output during product design in lectotype selection only carries out type selecting with experience in the past to equipment to the impact of equipment, disintegrating machine is often caused just to there will be significant rotor wear in operation less than in the time of half a year, thus cause the damage of rotor hammer dish large area, the distortion of hammer axle sleeve, hammer dish loosens, tup is shifted, cause hammer axle fracture by force unbalance, fall tup interrupts the equipment faults such as grid section, adds many difficulties to production maintenance.

Summary of the invention

Technical problem to be solved in the utility model how to make 2PCF-2022 single segment hammer type crusher rotor have good intensity and anti-wear performance, thus improve the service life of rotor.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of 2PCF-2022 single segment hammer type crusher rotor, comprise the hammer dish of rotor, end plate and hammer axle, on the hammer dish of described rotor, welding is hammered sleeve assembly into shape and is set up backplate, the hammer dish periphery of rotor evenly sets up five thrust axis, at hammer dish both sides build-up wear-resistant layer, the thickness of hammer dish is 60 millimeters, and the end face of hammer dish is established wear-resisting hat; The thickness of described end plate is 70 millimeters.

The utility model adopts the 2PCF-2022 single segment hammer type crusher rotor designed by technique scheme, because on the hammer dish of rotor, welding is hammered sleeve assembly into shape and set up backplate, the hammer dish periphery of rotor establishes thrust axis, at hammer dish both sides build-up wear-resistant layer, the end face of hammer dish is established wear-resisting hat, add the thickness of hammer dish and end plate, like this, ensure that and hammer dish, the requirement of end plate inner hole, strengthen the stability that hammer dish is installed, improve rotor integral rigidity, enhance erosion resistant ability, make the life-span more now can improve 30% with rotor, extend the normal cycle of operation of disintegrating machine, reduce disintegrating machine maintenance cost, alleviate the workload of workman, alleviate mining production and maintenance pressure.

Accompanying drawing explanation

Fig. 1 represents the structural representation of the utility model rotor;

Fig. 2 represents the structural representation of the utility model rotor hammer dish.

Detailed description of the invention

Illustrate below in conjunction with the structure of accompanying drawing to the utility model 2PCF-2022 single segment hammer type crusher rotor.

See Fig. 1 and Fig. 2, the utility model 2PCF-2022 single segment hammer type crusher rotor, comprise the hammer dish 2 of rotor 1, end plate 5 and hammer axle 3, wherein, on the hammer dish 2 of rotor 1, welding is hammered sleeve assembly into shape and is set up backplate 4, and hammer dish 2 periphery of rotor 1 evenly sets up five thrust axis 7, at hammer dish 2 both sides build-up wear-resistant layer 6, it is 60 millimeters that the thickness of hammer dish 2 is increased to by original 50 millimeters, and the end face of hammer dish 2 is established wear-resisting hat 8, and it is 70 millimeters that the thickness of end plate 5 is increased to by original 60 millimeters.Like this, the intensity that can strengthen hammer dish 2 prevents hammer dish 2 from ftractureing, and the integral rigidity strengthening rotor disk prevents the root of hammer dish 2 from snapping, and hammers axle shelves dish position into shape and thicken outside end plate 5, and the shelves dish protecting hammer axle 3 is not worn.The utility model selects U.S. LK811 wear resistance electrode, increases hammer dish 2 both sides wear-resistant protective layer, and wear time improves more than 50 ~ 100%.The utility model adopts the disposable machining spindle hole of large-sized numerical control boring and milling machine and hammer axle sleeve.

The utility model manufacturing process is:

1. first take the method protecting main shaft to remove to be pulled down from main shaft by hammer dish;

2. repair main shaft hammer dish prescription shape planar dimension (ensureing to require with hammer dish, end plate inner hole), strengthen the stability that hammer dish is installed, with supersonic detector, comprehensive defect detecting test is done to main shaft;

3. hammer dish, end plate blank make.With Q345(16Mn) steel plate cutting welding hammer dish assembly, J506 hydrogen controlled electrode is selected in welding or with the welding of ER50-6 welding wire CO2 gas shielded arc welding, welding rod dries rear welding on request, postheating insulation elimination welding stress;

4. end plate, hammer dish are installed on main shaft, after every sheet is loaded onto, measurement clearance coordinates processing wedge key through finishing repeatedly and trial assembly, the contact surface of key is made to obtain requirement, again key, firmly firmly in drive hammer dish, is installed rear clip, end cover compresses end plate (it is that hammer dish produces loosening main cause that wedge key and main shaft contact situation bad with hammer dish);

6. with special purpose machine tool, end plate, the axle sleeve hole boring of hammer dish hammer are led to, installing in disk body hole by processing hammer axle sleeve (endoporus Ф 138 external diameter Ф 170, material wear-resistant and good welding performance modifier treatment) assembly interference, sleeve assembly will be hammered into shape and weld with disk body; And then logical boring hammer axis hole ensures the axiality of hammer axis hole; Eddy-current heating process hammer inner hole of shaft sleeve, to ensure the wearability hammering axis hole into shape.Every block hammer dish is hammered axle respectively with the pre-boring drill diameter of the axisymmetric accurate location of rotor 110 millimeters of thrust axis installing holes into shape with 5, then entire body symmetry install 5 diameters 100 millimeters A3 round steel and between every block hammer dish firm welding, stablize thrust axis as hammer dish;

7. build-up wear-resistant layer.Wearing layer built-up welding thickness is not less than 6mm, finally adds heap one deck (wearing and tearing of this place are very fast) again to hammer axis hole place hammer dish;

8. carry out static balancing test and dynamic balancing watch test;

9. pair repair rotor and make antirust treatment.

Claims

1. a 2PCF-2022 single segment hammer type crusher rotor, comprise the hammer dish of rotor, end plate and hammer axle, it is characterized in that welding is hammered sleeve assembly into shape and set up backplate on the hammer dish of described rotor, the hammer dish periphery of rotor evenly sets up five thrust axis, at hammer dish both sides build-up wear-resistant layer, the thickness of hammer dish is 60 millimeters, and the end face of hammer dish is established wear-resisting hat; The thickness of described end plate is 70 millimeters.
