Description

Technical Field

[0001] This utility model relates to the technical field of rolling mill lubrication devices, and in particular to a shaft head lubrication device, a rolling mill, and a rolling mill. Background Technology

[0002] As a crucial component of the wire rod rolling production line, the precision of the rolls must be guaranteed before and during operation. In practice, the roll shaft head is connected to the universal joint sleeve. During operation, the gearbox drives the universal joint to rotate, thereby rotating the roll. The roll shaft head and the universal joint sleeve are constantly in a state of thermal friction after contact. Under this condition, the wear-resistant plates inside the roll shaft head and the universal joint sleeve rub against each other, resulting in mechanical wear. This wear creates gaps at the contact points, leading to roll slippage during operation. This can cause quality problems such as metallographic folding in the wire rod during rolling, and can also lead to steel pile-up accidents. Equipment damage is unavoidable, resulting in significant economic losses. Therefore, the roll shaft head needs to be lubricated before the rolls are put into operation. Operators typically apply grease to the roll shaft head while wearing gloves, wasting a pair of gloves with each application. Furthermore, lubricant may fall to the ground or splash onto the operators, further wasting grease.

[0003] A related technology provides a lubricating oil application device, including: an application shell, an application sponge, and an oil tank. The application shell has an elongated groove, the application sponge is disposed in the groove, and the oil tank is connected to the outside of the application shell. The oil tank can communicate with the space inside the groove through an oil hole so that lubricating oil can flow between the oil tank and the application sponge. However, during the application process, the amount of lubricating material seeping out from the oil hole cannot be adjusted, resulting in problems such as insufficient lubrication and uneven lubrication.

[0036] This embodiment provides a shaft end lubrication device for lubricating components, such as... Figure 1 and Figure 2As shown, the device includes a main body 1, a grease storage chamber 2, an applicator 3, a compressor (not shown in the figure), and a drive unit 4. The grease storage chamber 2 is fixedly connected to the main body 1. The grease storage chamber 2 has a discharge hole 21 on the side facing the main body 1. The grease storage chamber 2 contains grease. The applicator 3 is fixedly connected to the main body 1 or the grease storage chamber 2. The applicator 3 has an exudation hole 31 that communicates with the discharge hole 21. The side of the applicator 3 with the exudation hole 31 faces the object to be lubricated. The compressor is disposed in the grease storage chamber 2 and can come into contact with the grease. The drive unit 4 is disposed on the main body 1 and is pneumatically connected to the compressor. The drive unit 4 is used to drive the compressor to move so that it comes into contact with the grease.

[0037] The grease storage chamber 2 is filled with grease. The compressor is in its initial position. The drive unit 4 is activated, and the compressor moves towards the grease via the transmission mechanism. The compressor compresses the grease, creating flow pressure. The grease flows through the discharge hole 21 of the grease storage chamber 2 into the seepage hole 31 of the applicator 3. The grease seeps out from the seepage hole 31. By lifting the main body 1, the applicator 3 is moved, thus achieving the application of lubricant to the workpiece. This helps improve the sufficiency and uniformity of the lubrication application.

[0038] It should be noted that in this embodiment, the component to be lubricated is the shaft end of the roller. In other embodiments, the component to be lubricated can also be the inner wall of a sleeve or a rotating shaft, etc. No limitations are imposed here.

[0039] Specifically, in this embodiment, the applicator 3 is fixedly connected to the grease storage chamber 2. In other embodiments, the applicator 3 may also be fixedly connected to the device body 1. No limitation is imposed here.

[0040] Specifically, in this embodiment, the applicator 3 is snapped onto the grease storage chamber 2. In other embodiments, the applicator 3 may also be adhered to the grease storage chamber 2, etc. No limitation is made here.

[0041] Optionally, a compressor extends into the grease storage chamber 2, which can divide the grease storage chamber 2 into a first chamber and a second chamber, one of which contains grease and is connected to the discharge port 21, and the other of which is connected to air.

[0042] When the compressed component moves, the volume of the first chamber decreases, and the grease is squeezed out through the discharge hole 21. At the same time, the volume of the second chamber increases, drawing in air to prevent negative pressure from forming inside the chamber and hindering the movement of the compressed component. By utilizing the design of "one chamber for grease supply and one chamber for air replenishment", the internal pressure balance of the grease storage chamber 2 is maintained when the grease is discharged through the discharge hole 21, ensuring smooth delivery and avoiding contamination.

[0043] Specifically, such as Figure 1 As shown, in this embodiment, the compressor extends along a first direction within the grease storage chamber 2, forming a first chamber near the discharge hole 21 and initially storing grease, and a second chamber away from the discharge hole 21 and communicating with air. In other embodiments, the compressor may also extend along a second direction within the grease storage chamber 2, etc. No limitations are imposed here.

[0044] Optionally, in this embodiment, the compression element is a piston. In other embodiments, the compression element may also be a sealing plate, etc. No limitation is imposed here.

[0045] Optionally, in this embodiment, the grease storage chamber 2 is further provided with an inlet hole (not shown in the figure), which is used to replenish grease into the grease storage chamber 2. It should be noted that the inlet hole is connected to the first chamber.

[0046] Optionally, in this embodiment, the drive element 4 is a manual button. In other embodiments, the drive element 4 can also be a valve, etc. No limitation is made here. Specifically, in this embodiment, the drive element 4 is a manually press-type air nozzle. In other embodiments, the drive element 4 can also be an electric valve, etc. No limitation is made here.

[0047] Optionally, in this embodiment, the shaft end lubrication device further includes an air pipe, one end of which is connected to the second chamber, and the other end of which is connected to air. A manual button is located on the air pipe. By pressing the manual button, air from the other end of the air pipe enters the second chamber, thereby increasing the volume of the second chamber. In other embodiments, the shaft end lubrication device further includes an air compressor and an air pipe, one end of which is connected to the second chamber, and the other end of which is connected to the outlet of the air compressor. A manual button is located on the air pipe. By pressing the manual button, the air compressor is activated, and compressed gas enters the second chamber from the other end of the air pipe, thereby increasing the volume of the second chamber, etc. No limitations are imposed here.

[0048] Optionally, in this embodiment, the grease storage chamber 2 contains a delivery pipe (not shown in the figure). One end of the delivery pipe is connected to the discharge hole 21, and the other end of the delivery pipe is contained in the grease, allowing the grease to flow through the delivery pipe to the discharge hole 21. The delivery pipe ensures that the grease can reach the discharge hole 21 through its guidance, and the delivery pipe forms a closed channel to prevent the grease outside the delivery pipe from contacting external impurities.

[0049] Optionally, such as Figure 2As shown, multiple discharge holes 21 are provided, and the multiple discharge holes 21 are spaced apart. The multiple spaced discharge holes 21 allow the grease in the grease storage chamber 2 to expand the lubrication coverage area, so that the grease can directly act on multiple parts on the workpiece that need lubrication, reduce the loss of grease transmission path, optimize grease flow stability, reduce the flow pressure of a single channel, and allow the grease to flow out at a more stable rate.

[0050] Specifically, such as Figure 2 As shown, in this embodiment, the plurality of discharge holes 21 are evenly spaced along the second direction. In other embodiments, the plurality of discharge holes 21 may also be evenly spaced along the first direction, or the plurality of discharge holes 21 may be formed in a rectangular array in the grease storage chamber 2, or the plurality of discharge holes 21 may be formed in a ring array in the grease storage chamber 2, etc. No limitation is made here.

[0051] More specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, based on considerations of grease application uniformity, the projections of the plurality of discharge holes 21, evenly spaced along the second direction, onto the coating member 3 are positioned at the center of the coating member 3 along the first direction. In other embodiments, the plurality of discharge holes 21 can be located at any position on the coating member 3. No limitation is imposed here.

[0052] Optionally, such as Figure 1 As shown, the edge of the applicator 3 facing the part to be lubricated is recessed towards the center. When the applicator 3 contacts the head of the roll, the center of the applicator 3 contacts the head of the roll first. Since the discharge hole 21 is located at the center of the applicator 3, the grease can be applied to the head of the roll with the center of the applicator 3 as the application center. At the same time, the edge of the applicator 3 can further apply the grease already applied to the head of the roll, further improving the uniformity of lubrication of the head of the roll.

[0053] Specifically, the applicator 3 is an applicator sponge. The applicator sponge is soft and elastic, and its porous surface structure gives it good adsorption and extensibility. The applicator sponge can spread the grease more evenly, which helps to improve the uniformity and thoroughness of lubrication. In addition, the applicator sponge can be washed and reused, making it cost-effective.

[0054] More specifically, the recessed design of the applicator sponge allows the center of the sponge to form a grease reservoir. When the edge of the sponge contacts the part to be lubricated, the grease penetrates from the center to the edge, reducing dripping and waste.

[0055] Optionally, such as Figure 1As shown, the main body 1 of the device includes a storage chamber mounting part 11, which is U-shaped. Two grease storage chambers 2 are provided, positioned opposite each other on the storage chamber mounting part 11. Discharge holes 21 are also opposite each other. Two applicators 3 are provided, each fixedly connected to one of the two grease storage chambers 2. When lubricating the roller shaft end, the roller shaft end is located inside the U-shaped storage chamber mounting part 11. The symmetrically arranged grease storage chambers 2 and applicators 3 enable bidirectional lubrication, ensuring uniform lubrication coverage and improving lubrication efficiency.

[0056] Optionally, such as Figure 1 and Figure 2 As shown, the main body 1 of the device includes a storage compartment mounting part 11 and a handheld part 12. One end of the storage compartment mounting part is fixedly connected to a grease storage compartment 2, and the other end of the storage compartment mounting part is fixedly connected to the handheld part 12. The handheld part 12 provides a gripping area for easy operation of the device by the user.

[0057] This embodiment also provides a rolling mill roll, including a rolling mill roll body and rolling mill roll heads. The rolling mill roll heads are disposed on both sides of the rolling mill roll body, and the rolling mill roll heads are lubricated by a roll head lubrication device. This ensures the lubrication effect of the rolling mill roll before use.

[0058] This embodiment also provides a rolling mill, including a rolling mill body and rolling rolls, with the roll shaft ends connected to the rolling mill body. This avoids wear between the roll shaft ends and the rolling mill body, ensures the normal rotation of the rolls within the rolling mill body, and improves product quality.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
