Description

Technical Field

[0001] This utility model relates to the field of pneumatic oil supply technology, and more specifically to a pneumatic oil supply device for oil-air lubrication of a cold rolling mill. Background Technology

[0002] During the operation of a cold rolling mill, the lubrication system is the core device ensuring the normal operation of its critical components (such as bearings, gears, and rolls). Oil-air lubrication, as a highly efficient, energy-saving, and environmentally friendly lubrication method, has been widely used in modern cold rolling equipment. This system mixes lubricating oil with compressed air and delivers it to the lubrication points in a precisely controlled manner, achieving a continuous, minute, and uniform lubrication effect.

[0003] In oil-air lubrication systems, pneumatic oil supply devices are a crucial component, typically including a pneumatic motor, oil pump, control valve, oil tank, and related piping. The pneumatic motor, as the core power source driving the oil pump, directly impacts the performance of the lubrication system. However, existing pneumatic oil supply devices for cold rolling mill oil-air lubrication systems still have some shortcomings in their structural design, particularly regarding the installation and maintenance of the pneumatic motor, which poses significant difficulties for daily maintenance and troubleshooting.

[0004] In traditional structures, pneumatic motors are usually fixed to brackets with multiple bolts. Disassembly requires multiple tools and takes a lot of time, which affects the maintenance efficiency of the equipment.

[0005] Therefore, it is necessary to propose a pneumatic oil supply device for oil-air lubrication in cold rolling mills to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 A pneumatic oil supply device for oil-air lubrication of a cold rolling mill includes a base plate 1. An H-shaped rod 3 is fixedly connected to one side of the base plate 1. A pneumatic motor 12 is detachably mounted on the H-shaped rod 3, such as different models of motors manufactured by Gaston. However, the difference is that a top plate 4 is welded to the upper end of the H-shaped rod 3 for mounting the pneumatic motor 12. A mounting plate 13 is fixedly connected to the upper end of the pneumatic motor 12 and is detachably mounted on the top plate 4. A gear pump 2 is fixedly connected to the upper end of the other side of the base plate 1. The output shaft of the pneumatic motor 12 is connected to the input shaft of the gear pump 2 by a key. The inlet of the gear pump 2 is connected to an oil tank through a pipeline to realize oil pumping. The outlet of the gear pump 2 is connected to the oil spray end of the cold rolling mill through a pipeline to realize oil dispensing.

[0025] Specifically, in order to achieve the pre-positioning and installation of the mounting plate 13, a slot 5 is provided on the upper surface of the top plate 4, and an L-shaped insert plate 14 is fixedly connected to the mounting plate 13. The end of the insert plate 14 extends beyond the mounting plate 13 by a certain distance, so that the insert plate 14 can be inserted into the slot 5 first during installation to achieve the pre-positioning function.

[0026] Specifically, the upper end of the H-shaped rod 3 is elastically slidably connected to the insertion rod 9, and the end of the insertion plate 14 is provided with an insertion hole 16 for the insertion rod 9 to be inserted. When the insertion rod 9 is inserted into the insertion hole 16, the insertion plate 14 is locked.

[0027] Specifically, the end of the insert plate 14 is provided with a slanted groove 15, and the end of the insert rod 9 is provided with a slanted surface 10 that cooperates with the slanted groove 15. When the insert plate 14 is pushed into the slot 5, the insert plate 14 contacts the slanted surface 10, squeezing the insert rod 9 to retract into the sliding cavity 6, and then, under the action of the spring 8, it drives the slider 7 and the insert rod 9 to be inserted into the insertion hole 16.

[0028] Specifically, the upper end of the H-shaped rod 3 has a sliding cavity 6, in which a slider 7 is slidably connected. The insert rod 9 is fixedly connected to the side of the slider 7, and a spring 8 is fixedly connected to the other side of the slider 7. The other end of the spring 8 is fixedly connected to the H-shaped rod 3.

[0029] Specifically, a lever 11 is fixedly connected to the upper end face of the insertion rod 9. By moving the lever 11, the insertion rod 9 can be easily moved out of the insertion hole 16, thereby unlocking the insertion plate 14 and disassembling the pneumatic motor 12.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. The scope of patent protection of this utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of this utility model shall also be included within the scope of protection of this utility model.
