Description of the working principle:
the sectional dimension range of the blank which can be forged by the horizontal radial forging machine is 20 mm-850 mm (25 mm-750 mm square steel) in diameter. That is, large-sized shaft members can be forged, and ordinary small-sized shaft members can be forged as well. Both round steel and square steel can be forged.
As shown in figure 2, the transmission case 4 is hinged with the pin shaft 13 and is connected with the transmission case through a bolt, bolt holes are formed in the rack and the transmission case, the case body cannot rotate around the pin shaft through the bolt connection, and the case body can rotate for 90 degrees around the pin shaft after the bolt is removed during maintenance of the equipment case body so as to be convenient for maintenance.
Radial feed action principle:
the eccentric sleeve is connected with a pull rod of the radial feeding mechanism through a pin shaft, the eccentric sleeve is pulled by adjusting the position of the pull rod in the radial feeding mechanism, the eccentric sleeve rotates to drive the eccentric shaft to displace to change the central position of the eccentric shaft, and the central position of the eccentric shaft is changed to change the hitting distance of the hammer rod to complete the telescopic feeding action so as to adapt to the forging of blanks with different radiuses.
The eccentric sleeve is directly arranged in the forging box body and is fixed with the forging box body in tandem through two compression rings, and the front and the rear of the eccentric sleeve are respectively connected with a pin shaft on the forging box body through a pin shaft on the eccentric sleeve 251.
The working principle of the forging box is as follows:
the eccentric sleeve is installed in the forging box and connected with the upper end and the lower end of the eccentric shaft, the motor drives the transmission box to be transmitted to the slide block on the eccentric shaft driving shaft through the cross plate coupler, the slide block drives the connecting rod to do reciprocating motion in the forging box, the pull rod in the radial feeding mechanism is connected with the eccentric sleeve through the pin shaft, the eccentric sleeve is pulled by adjusting the position of the pull rod in the radial feeding mechanism, the eccentric sleeve rotates to drive the eccentric shaft to displace to change the central position of the eccentric shaft, and the central position of the eccentric shaft changes to change the hitting distance of the hammer rod to complete the telescopic feeding action so as to adapt to the forging of blanks with different radiu.
As shown in figure 19, the gear transmission relationship is that two big gears rotate clockwise and the other two rotate anticlockwise, so that the synchronous motion of the hammers is considered, the design method can ensure that the four hammers have better synchronism and stronger stability, and the adopted bevel gear has small volume, light weight, large transmission torque, smooth starting, fine transmission ratio grading and low noise.
Unified power input in this application compares in four motor drive, unified power input precision is higher in this application, and stability is stronger, and the synchronism is better, and the forging precision is higher.
The working principle of the radial feeding mechanism is as follows:
two hydraulic motor divide into two sets ofly, and the flexible volume of two tups of oblique diagonal angle is controlled through radial feed mechanism to every group motor, and two motors are synchronous rotation when forging the round steel, and two motors are asynchronous rotation when forging the square steel. The rotating circles of the two motors are different, so that the telescopic amount of the pull rod in the radial feeding mechanism for controlling each pair of hammers is different, the rotating angle of the eccentric sleeve connected with the pull rod is different, and the telescopic amount of each pair of hammers is adjusted to adapt to the forging of square steel.
The working principle of the auxiliary mechanism is as follows:
as shown in fig. 17, the feeding mechanism is arranged in parallel with the feeding mechanism to feed the material, and the material turning mechanism is arranged between the feeding mechanism and the feeding mechanism to turn the material from one side to the other side.
The feeding mechanisms are arranged in two sets and are respectively positioned at the front side and the rear side of the forging box.
In a similar way, the material turning mechanisms are also provided with two sets, one set is used for feeding, and the other set is used for discharging.
The working process of the invention is as follows:
selecting a proper hammer head according to the cross section shape of a shaft part or a pipe part to be forged, feeding a blank to a chuck by a feeding device 53, clamping the blank by the chuck, then intermittently rotating the blank and approaching the blank to the hammer head 27 direction, clamping and centering the blank by a centering device, transmitting power to a transmission box 4 by a motor, transmitting the power to a forging box 20 by the transmission box 4, enabling the hammer head 27 to reciprocate by a proper stroke under the action of an eccentric shaft 21, an eccentric sleeve 22 and a connecting rod 23, starting forging after the blank contacts the hammer head 27, feeding the blank by the intermittent rotation of the chuck, measuring the feeding data of the hammer head 27 by a measuring device in real time, feeding the feeding data to a control system, and finishing the forging work under the automatic control of the electric control system; meanwhile, a chuck of a feeding mechanism positioned on the other side of the forging box synchronously rotates to abut against the blank, the centering device loosens, the chuck clamps, the speed matching retreats, the material supporting bracket rises, the chuck loosens and returns, the chuck clamps a workpiece to forge, after the forging is finished, the chuck retreats, the material is discharged by a material turning mechanism, and the material is placed on a material placing frame 57.
The main forging force acts on the rack, the structural form of the rack can have extremely high strength and rigidity, and the rack can be allowed to bear the extremely high forging force, which is the key point of the invention for successfully forging the large-scale shaft parts.
