Detailed Description
In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings:
as shown in fig. 1, the technical solution of the present invention is:
a lower rotary device for a rotary extrusion press, which achieves the following objectives:
1. the action of rotation can be realized;
2. the main tonnage can be counteracted under the condition of large-tonnage vertical pressing force, and the rotation action is carried out;
3. the good sealing state of the oil cylinder during rotation can be ensured;
4. the heat insulation effect can be effectively realized when a high-temperature workpiece is pressed;
the concrete structural connection is as follows:
the plunger 12 is attached with a nut B13 and fastened to the movable table body 14 by a connecting bolt E21. The rotary bearing 6 is installed on the upper end of the plunger 12, the cylinder 4 is placed on the rotary bearing 6, and the horizontal rotary motion of the cylinder 4 can be realized due to the support of the rotary bearing 6. Guide sleeve B7 is installed between plunger 12 and the lower end of cylinder 4, and in order to ensure the device's tightness, static seal 22 is installed between guide sleeve B7 and cylinder 4, and rotary seal B10 is installed between plunger 12, and guide sleeve B7 is pressed inside the device through cylinder mouth flange A8, prevents the up-and-down movement, and cylinder mouth flange 8 is fastened on cylinder 4 through connecting bolt D20. Guide bush A3 is installed between plunger 12 and the upper end of cylinder 4, and guide bush A3 is pressed in the device through cylinder opening flange B11 to prevent the up-and-down movement, and is fastened on cylinder 4 through connecting bolt B18, and static seal 22 is installed between guide bush A3 and cylinder 4 in order to ensure the tightness of the device, and rotary seal A9 is installed between plunger 12. The arrangement of the rotary seal can ensure the good sealing state of the oil cylinder of the rotary device during rotation, and the condition of oil leakage cannot occur. Under the large-tonnage vertical pressure, the rotary bearing can not bear huge vertical pressure, the oil cylinder applies system pressure through a power system, pressure with the same tonnage is applied in the vertical reverse direction to offset the main tonnage, and the cylinder body still freely rotates on the rotary bearing, so that the main tonnage is offset under the large-tonnage vertical pressing force to perform rotation action. The cylinder 4 is connected with a nut A5 and is fastened on the gear 15 through a connecting bolt C19, and the rotating force of the rotating device is provided by a transmission mechanism driving the gear 15. A positioning key is arranged between the gear 15 and the cylinder body 4, so that the gear 15 and the cylinder body 4 are prevented from moving in a dislocation mode during rotation. The rotating platform 1 is installed on the cylinder body 4 and fastened on the cylinder body 4 through a connecting bolt A17, and the heat insulation plate 2 is arranged between the rotating platform 1 and the cylinder body 4, so that heat insulation can be effectively realized when high-temperature products are pressed, heat is prevented from being transmitted to an oil cylinder part to damage a sealing element, and the sealing life is effectively prolonged.
The working principle of the preferred embodiment is as follows:
when the equipment is in normal operation, the plunger 12 is fixed on the workbench body 14, the driving system drives the gear 15 to rotate, so as to drive the cylinder body 4 to rotate, because the rotary table 1 and the cylinder body 4 are fixed together, the rotary table 1 can perform passive rotary motion, when the equipment vertical direction pressure is loaded on the rotary table 1, the rotary bearing 6 bears the pressure in a smaller pressure interval, the rotary table 1 is ensured to rotate, when the applied pressure is increased, the hydraulic oil begins to be filled into the inner cavity of the oil cylinder to improve the pressure of the inner cavity, the equal pressure is provided by the hydraulic oil, the vertical loading pressure of the equipment on the rotary table 1 is resisted, and the normal operation of the rotary table 1 is ensured.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
