Background technology
At present, in metalworking technology, the forcing press that forging and molding adopts all is that employing forges, the mode of punching press is processed workpiece, and the face pressure request is big, crystallized ability is low, efficient is low, and the final thickness of workpiece that forms is limited, can not be too thin.In addition, the parts for complexity are difficult for shaping.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, the object of the present invention is to provide a kind of stone roller to forge machine, its crystallized ability height, production efficiency height.
In order to address the above problem, the present invention by the following technical solutions: this grinds forging machine, comprise frame, be used for placing bed die workbench, be used for installing the main shaft of mould, also comprise motor and the gear wheel that is connected with the output wheel of motor; Motor is installed on the frame; Described gear wheel axis vertically arranges, and the axis of described main shaft intersects in same plane with the axis of described gear wheel; The top of main shaft is connected by bearing, eccentric bushing and gear wheel off-centre, and described bearing is assemblied between eccentric bushing and the main shaft, and eccentric bushing is inlaid in the gear wheel; The top of the main shaft anti-lost nut that has been threaded; Be equipped with first axle sleeve on the main shaft, and first axle sleeve is fixedlyed connected with gear wheel, and the bottom face of eccentric bushing is pressed on the first axle sleeve top end face, and first axle sleeve is installed in second axle sleeve by bearing, fixedly connected with a crossbeam in the bottom of second axle sleeve, described crossbeam is fixed on the frame; Main shaft passes described crossbeam, and the main shaft bottom is provided with axle journal and axle journal is positioned at the crossbeam below, the diameter of self-aligning thrust roller bearing and axle journal is arranged less than the external diameter of self-aligning thrust roller bearing with the axle journal matched in clearance, installs between described self-aligning thrust roller bearing and the crossbeam.
As the further technical scheme of the present invention:
Grind in the forging machine at this, the below of described workbench is installed with the hydraulic cylinder of control worktable lifting; Described workbench is slidingly mounted on the lead that vertically fixedly installs.
Grind in the forging machine at this, described workbench is provided with for the bed die installing hole of placing bed die, is provided with below this bed die installing hole be used to the liftout tank that ejects workpiece in the bed die; The bottom of the housing of described liftout tank is coaxial affixed with the piston rod of described hydraulic cylinder, and housing top and the described workbench of liftout tank are affixed.
Grind in the forging machine at this, the crosspoint of the axis of described main shaft and the axis of described gear wheel is positioned at the center of self-aligning thrust roller bearing.
Grind in the forging machine at this, be provided with a radial bearing, a thrust bearing between the top of described first axle sleeve and second axle sleeve, also establish a radial bearing, a thrust bearing between the bottom of first axle sleeve and second axle sleeve, and the bottom of first axle sleeve locking nut that has been threaded; The described bottom face that is positioned at the thrust bearing of the first axle sleeve bottom is pressed on the described locking nut.
Grind in the forging machine at this, the top of described main shaft and the bearing between the eccentric bushing comprise a radial bearing, a thrust bearing.
The invention has the beneficial effects as follows:
(1) because the contact area of mold and workpiece is little, so just can obtain bigger shaping amount with less pressure, crystallized ability exceeds doubly a lot than original hydraulic press, namely improved operating efficiency and reduced energy resource consumption simultaneously;
(2) because rotation rolls forging, the bed die of restriction workpiece profile is less by the pressure that workpiece affords, so resistance is also little during the demoulding, and the demoulding easily;
(3) to the shaping of the discoideus product of thin-walled, the backward extrusion of cup-shaped product, especially has good crystallized ability; The product that can be used for the machining shape complexity;
(4) because workpiece is local the contact with mold, and low with the contact-making surface pressure of bed die, so workpiece is few by the heat radiation of metal pattern, namely use low speed processing, the temperature reduction of workpiece also is little.Therefore to the material as the strong high resistance of deformation of titanium alloy equitemperature dependence, adopt rotation to roll forging, just can in narrower temperature range, carry out low speed processing.So this stone roller forging machine can be used for the material of difficult processing to shape.
Description of drawings
The present invention is described further below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the structural representation between gear wheel, main shaft, first axle sleeve, second axle sleeve;
Among the figure: 1 frame, 2 workbench, 21 bed die installing holes, 3 bed dies, 4 main shafts, 5 molds, 6 motors, 7 gear wheels, 8 eccentric bushings, 9 anti-lost nuts, 10 first axle sleeves, 11 second axle sleeves, 12 crossbeams, 13 self-aligning thrust roller bearings, 14 hydraulic cylinders, 141 piston rods, 15 leads, 16 liftout tanks, 17 locking nuts.
The specific embodiment
As shown in Figure 1, this stone roller forging machine comprises frame 1, be used for to place the workbench 2 of bed die 3, be used for installing the main shaft 4 of mould 5, also comprises motor 6 and the gear wheel 7 that is connected with the output wheel of motor.
The top of the main shaft 4 anti-lost nut 9 that has been threaded.Be equipped with first axle sleeve 10 on the main shaft 4, and first axle sleeve 10 fixedlys connected with gear wheel 7, the bottom face of eccentric bushing 8 is pressed on first axle sleeve, 10 top end faces.First axle sleeve 10 is installed in second axle sleeve 11 by bearing, be provided with a radial bearing, a thrust bearing between the top of first axle sleeve 10 and second axle sleeve 11, also establish a radial bearing, a thrust bearing between the bottom of first axle sleeve 10 and second axle sleeve 11, and the bottom of first axle sleeve 10 locking nut 17 that has been threaded; The bottom face that is positioned at the thrust bearing of the first axle sleeve bottom is pressed on the described locking nut 17.Fixedly connected with a crossbeam 12 in the bottom of second axle sleeve 11, described crossbeam 12 is fixed on the frame 1.
