Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of rotary table of forging hydraulic press is provided.Realized the hydraulic operation of rotary table by the hydraulic motor transmission, but automation control has improved the production efficiency of hydraulic press.On working plate, be provided with the technology backing plate, protected working plate, improved life tools.
The present invention is achieved through the following technical solutions its goal of the invention.
A kind of rotary table of forging hydraulic press, comprise: be arranged on the base on the movable workbench of hydraulic press, and the working plate that is connected with bearing with base, it is characterized in that: it is to adopt a kind of turntable bearing that the bearing between working plate and the base connects, its inner ring and working plate are linked together, the outer ring is fixed on the base, the hydraulic motor that has a pinion is installed in the inner and base of rotary table and fixes, the internal tooth engagement of pinion and turntable bearing, the technology backing plate is set on the working plate and locatees with round pin, in base, the dish spring is installed under the outer ring of turntable bearing, and hydraulic motor is connected with hydraulic quick coupler on being installed in travelling table.
Between described working plate and the base copper sheathing is housed.The technology backing plate is set on the described working plate, is to be connected with working plate with bolt in the breach of technology backing plate side.Described working plate and base are provided with protective cover outward, and protective cover is fixed with bolt and working plate, have on the protective cover in the circumferential groove of garden pin insertion base.Described travelling table is equipped with protective frame.The lubrication connection of lengthening is equipped with in the outer ring of described turntable bearing.
The present invention compared with prior art, owing to adopt the hydraulic motor of high pulling torque, be converted into mechanical rotation movement by hydraulic drive, realized the hydraulic operation of rotary table, not only workbench rotation frictional resistance is little, rotation at the uniform velocity, help improving the forging precision of forging, and can show automation control, improved production efficiency.Owing on working plate, be provided with the technology backing plate, can on the technology backing plate, forge workpiece, protected working plate, and when the backing plate serious wear the less technology backing plate of replaceable weight ratio, not only saved expense but also improved life tools.
Description of drawings
Fig. 1 is a kind of structural representation of rotary table of forging hydraulic press.
Also the present invention is further illustrated by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, a kind of rotary table of forging hydraulic press comprises: be arranged on the base 2 on the movable workbench of hydraulic press 14, and the working plate 1 that is connected with base 2 usefulness bearings.It is to adopt a kind of turntable bearing 5 that bearing between its working plate 1 and the base 2 connects, and its inner ring is connected with working plate 1 by 36 screws 16, and the outer ring is fixed on the base 2 with 12 pins 10.It is inner and base 2 is fixing that the hydraulic motor 3 that has a pinion 4 is installed in rotary table, and pinion 4 meshes with the internal tooth of turntable bearing 5.Drive hydraulic motor 3, by the pinion 4 and the internal tooth engaged transmission of turntable bearing 5 the rotatablely moving of platform of finishing the work.Turntable bearing 5 is installed in rotary table inside, makes it away from polluting and heat radiation, helps protecting turntable bearing.
It is in order to protect working plate, forge workpiece on technology backing plate 6, the less technology backing plate of replaceable weight ratio when the backing plate serious wear that technology backing plate 6 is set on the working plate 1.Locate with round pin 13 between technology backing plate 6 and the working plate 1, and bear the forging offset loading force.
Dish spring 7 is installed under the outer ring of 2 li of bases, turntable bearing 5, and string has bearing pin in the dish spring, is used for dish spring guiding.When forging workpiece, dish spring 7 is compressed, the last plane contact of the lower plane of working plate 1 and base 2, and forging force is passed to travelling table 14, and then passes to press.Dish spring 7 jack-up working plates 1 make it break away from base 2, are driven by hydraulic motor 3, finish the rotation of workpiece.
Hydraulic motor 3 is connected with hydraulic quick coupler 12 on being installed in travelling table 14, can realize fast quick-detach rotary table.
On the described working plate 1 technology backing plate 6 is set, be in the breach of technology backing plate side, to be connected with working plate 1 with bolt 17, avoid owing to reasons such as distortion, oxide skin obstruction cause technology backing plate 6 dismounting difficulties, technology backing plate 6 is solid, and oxide skin falls on the work top when avoiding forging.
Between described working plate 1 and the base 2 copper sheathing 11 is housed, in order to reduce the friction that working plate rotatablely moves.
Be provided with protective cover 8 outside described working plate 1 and the base 2, protective cover is fixed with bolt and working plate, and protective cover 8 is fitted with working plate 1, does not stay the gap, and rotates with working plate.Have garden pin 18 on the protective cover 8 and insert in the circumferential groove of base 2, be used to limit the extreme higher position of working plate.
Described travelling table 14 is equipped with protective frame 15, is used to protect flexible pipe, pipe joint, the hydraulic quick coupler 12 of hydraulic motor.
The lubrication connection 9 of 9 lengthenings is equipped with in the outer ring of described turntable bearing 5, is used for hand oiling.
The operation principle of the present invention and the course of work:
Rotary table is to overlap independently forging tools, is applicable to the rotary squeeze of some special forging and planishes operation.During application, be suspended to the heading die station of travelling table, the hydraulic-driven oil sources has been connected in the snap joint of travelling table, the cover plate of one jiao of travelling table is opened, the joint flexible pipe that is installed in the swaging workbench is connected with snap joint in being contained in travelling table, can the swaging workbench be operated by manually control on the operating desk.
Butterfly spring is supporting working plate, keeps and the base disengaged position, makes it to rotate on the rolling bearing of band gear.When last anvil pressurization was forged, working plate compression spring made heart portion contact with base, to bear and to transmit the forging pressure of press, forging force is delivered on the mobile working platen.After last anvil promoted, the butterfly spring restoring force made the working plate come-up, is rotated by the fluid motor-driven workbench again.
