Description
Technical field
The present invention relates to forging equipment, particularly a kind of forging tools.
Background technology
When forge carries out cogging and forges axial workpiece, need lift rotary working table is used in the forging tune usually.This equipment configuration in rail translational operation unit, and be placed between manipulator and the forging equipment, in the melt pit on the manipulator track centerline.When not working, lift rotary working table drops to the place, plan-position, and during work, workbench rises, and manipulator is placed on steel ingot or forging on the workbench that has risen, and 180 ° of work table rotations are realized the tune of forging.
The lift rotary working table for forging of prior art, not only lifting is that rigidity connects, and buffering effect is poor, when steel ingot is placed on the workbench by shop traveller or manipulator, cause can not guarantee that its center of gravity drops on the center of workbench, thus there are eccentric load in hoist cylinder and guider, thus cause the damage of cylinder seal and guider, and it is bigger again to change sealing and repair guider difficulty, has reduced operating efficiency.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of lift rotary working table for forging is provided, solved that prior art lowering or hoisting gear rigidity connects, the technical problem of buffering effect difference, avoid steel ingot or forging to put into and broken away from the harmful effect that the workbench process causes unbalance loading, has good buffering effect, prolong the service life of parts widely, improved operating efficiency.Simultaneously, because workbench general frame structural rigidity is good, guaranteed the stability of workbench.
The present invention is achieved through the following technical solutions:
A kind of lift rotary working table for forging, comprise: the forging supporting base, the slewing equipment that is connected with the forging supporting base, the elevating mechanism that is connected with slewing equipment, and guider, it is characterized in that: be provided with the buffer unit of forming by buffering bearing, dish spring guide holder, dish spring between described forging supporting base and the slewing equipment, dress dish spring guide holder and dish spring in the buffering bearing, dish spring guide holder top is connected with the forging supporting base, and the buffering bearing is connected with slewing equipment; Described slewing equipment is made up of internal-gear type turntable bearing, pinion, hydraulic motor, the outer ring of turntable bearing is installed in the top of described guider, the ring gear of turntable bearing is installed in described buffering bearing bottom, and with two pinion, two hydraulic motors drive two pinions respectively; Described guider is divided into interconnected leading truck and following leading truck two parts gone up, last leading truck is a cylindrical tube, the inner hydraulic motor of installing, following leading truck is eight prismatic cylindrical shells, the 45 ° of directions in side, upper-lower position are installed the four rolling device respectively, its roller is equipped with dish spring group along the frame scroll-up/down between roller devices bottom and the following leading truck; Described elevating mechanism is mounted in down in the leading truck, is positioned at the hydraulic cylinder at leading truck center, the upper articulation of its cylinder head and following leading truck, and cylinder bottom is hinged on the base of frame.
Adorn eight groups of dish spring guide holders and dish spring in the described buffering bearing; Be provided with guide plate between the roller of described roller devices and the frame; Described frame is sealing stress frame structure; Described forging supporting base top is provided with cross " V " the type groove that varies in size.
The present invention compared with prior art has the following advantages and beneficial effect:
1. forging supporting base top is cross " V " type groove, applicable to the forging process for fuel of specification (Φ 300～Φ 2000) on a large scale.
2. when the dish spring in the buffing pad effectively absorbs placement, clamping steel ingot and forging to the impact of this device.
3. adopt turntable bearing to realize 360 ° of arbitrary angle rotaries of steel ingot and forging.
4. hydraulic cylinder is realized the lifting of steel ingot and forging, and hydraulic cylinder cylinder head and cylinder bottom are articulated structure, can cushion the lateral impact power that this device is subjected to.
5. lift rotary partly by eight roller devices, is 45 ° of directions and is fixed in the closed frame, has guaranteed the stability of device.
6. the dish spring of roller devices bottom can absorb the lateral impact power that buffer unit is subjected to.
7. adopt two pinions of two fluid motor-driven to drive the turntable bearing ring gear jointly and rotate, broken through low-speed big torque motor type selecting bottleneck, make turntable bearing stressed more reasonable, reduced the ring gear Contact Stress of Gear.
In a word, the present invention puts into and breaks away from the process of workbench at steel ingot or forging, and no matter vertical direction still is a horizontal direction all good buffering effect, has prolonged the service life of parts widely, has improved operating efficiency.Simultaneously, frame general frame structure, good stability.
