Description

Technical Field

[0001] This utility model relates to the field of machine tool cooling and lubrication technology, and in particular to an automatic spray lubrication device. Background Technology

[0002] In the forging process of wheel disc parts, the forging mold used in each process consists of two parts: an upper mold and a lower mold. Since the mold will come into direct contact with the high-temperature workpiece during the forging process, generating a lot of heat, and impurities such as oxide scale are easily left in the mold cavity, it is necessary to equip the mold with a special spray lubrication device.

[0003] The existing lubrication solution involves storing lubricant in a pressure tank and manually spraying it. Liquid lubricant is stored in a special pressure tank, and operators use handheld spray guns to spray the lubricant onto the mold cavity between each forging operation. However, the manual spraying process suffers from unstable atomization. Since the atomization effect of the spray gun depends on the coordinated matching of atomizing air pressure and liquid pressure, local lubrication deficiency or accumulation may occur. Alternatively, over-atomization may occur, resulting in lubricant waste, which not only reduces the lubrication effect but also makes the forging surface prone to scratches, cracks, or poor forming defects.

[0004] Therefore, a new automatic spraying lubrication device is needed to solve the problem of unstable lubrication effect of manual atomization. Utility Model Content

[0005] The purpose of this application is to provide a new automatic spray lubrication device that can solve the problem of unstable lubrication effect of manual atomization.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] This utility model provides an automatic spraying lubrication device, comprising: a cylinder body with a receiving cavity inside; a connector one, which is fixedly disposed in the receiving cavity and located above the receiving cavity, and is used to connect to an air source; a connector two, which is disposed on the outer wall of the cylinder body and communicates with the receiving cavity, and is used to deliver lubricating fluid; a fluid outlet, which is disposed on the outer wall of the cylinder body and located at the bottom of the cylinder body; a piston rod one, which is slidably disposed in the receiving cavity, and has a sliding cavity inside the piston rod one, and has a connecting sleeve on the piston rod one, and has a groove at the bottom of the connector one that cooperates with the connecting sleeve; and a piston rod two, which is slidably disposed in the sliding cavity of the piston rod one.

[0008] Furthermore, a piston is fixedly mounted on the piston rod, and the piston slides on the inner wall of the cylinder. A connecting hole is provided in the middle of the piston.

[0009] Furthermore, a second piston is fixedly mounted on the second piston rod, and the second piston is slidably mounted on the inner wall of the first piston rod and located within the sliding cavity.

[0010] Furthermore, the top of the cylinder body is provided with a connecting part, the inner wall of the connecting part is provided with a boss, and a retaining ring is fixed above the boss. The retaining ring cooperates with the boss to restrict the vertical position of the connector.

[0011] Furthermore, a plug is provided at the bottom of piston rod one, which is used to drive piston rod one and piston rod two to reset under external pressure.

[0012] Furthermore, piston two can slide along the inner wall of the sliding cavity, and the outer diameter of piston two is adapted to the inner diameter of the sliding cavity.

[0013] Furthermore, a limiting sleeve is provided at the bottom of the cylinder block, which is used to limit the downward movement limit of the piston.

[0014] Furthermore, a second retaining ring is provided at the bottom of the cylinder body. The second retaining ring is located below the first limiting sleeve and is used to fix the position of the first limiting sleeve.

[0015] Furthermore, a limiting sleeve 2 is provided at the bottom of the sliding cavity, which is used to limit the downward movement limit position of piston 2.

[0016] Furthermore, a retaining ring three is provided at the bottom of the sliding cavity. The retaining ring three is located below the limiting sleeve two and is used to fix the position of the limiting sleeve two.

[0017] The technical effects are as follows:

[0018] When the device is in the reset state, the connecting sleeve is inserted into the groove at the bottom of the connector. When the piston slides along the inner wall of the cylinder, gas can flow between the receiving cavity and the sliding cavity through the connecting hole. When the upper mold and the lower mold are separated, sufficient space is left for the movement of piston rod 1 and piston rod 2. Through the two-stage linkage structure of piston rod 1 and piston rod 2, the air source pressure drives piston rod 2 to move down to the limiting sleeve 2 first to prevent the lubricant from being sprayed out prematurely, causing waste or insufficient spraying. Then, it drives piston rod 1 to move down to below connector 2, which can accurately output the lubricant pre-stored in the gap between piston rod 1 and the inner wall of the cylinder, realizing the effect of automated lubrication spraying and solving the problem of unstable effect of manual atomized lubrication.

Furthermore, all embodiments can be used in combination with each other.

[0031] Example 1:

[0032] like Figure 4 As shown in this embodiment, for the mold mating mechanism in metal processing equipment, such as the upper and lower molds 4 used in forging equipment, most existing equipment uses manual lubrication. This involves a separate operator holding a spray gun connected to the spraying device 1, extending the spray gun between the upper mold 2 and the lower mold to spray lubricant into the mold cavity when they open and close. This method is labor-intensive and inefficient. Therefore, a new automatic spraying lubrication device is needed to solve the above problems. Devices that can improve the spraying lubrication device to solve the above problems include the following:

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, an automatic spraying lubrication device of this utility model includes: a cylinder 101, which has a receiving cavity; a connector 102, which is fixedly disposed in the receiving cavity and located above the receiving cavity, and is used to connect to an air source; a connector 8, which is disposed on the outer wall of the cylinder 101 and communicates with the receiving cavity, and is used to transport lubricating fluid; a liquid outlet 107, which is disposed on the outer wall of the cylinder 101 and located at the bottom of the cylinder 101; a piston rod 5, which is slidably disposed in the receiving cavity, and has a sliding cavity inside the piston rod 5, and has a connecting sleeve 104 on the piston rod 5, and the bottom of the connector 102 has a groove that cooperates with the connecting sleeve 104; and a piston rod 6, which is slidably disposed in the sliding cavity of the piston rod 5.

[0034] Specifically, a piston 501 is fixedly mounted on the piston rod 5, and the piston 501 is slidably mounted on the inner wall of the cylinder 101. A connecting hole is provided in the middle of the piston 501.

[0035] Specifically, piston 2 601 is fixedly mounted on piston rod 2 6, and piston 2 601 is slidably mounted on the inner wall of piston rod 1 5 and located in the sliding cavity.

[0036] Specifically, the top of the cylinder body 101 is provided with a connecting part, the inner wall of the connecting part is provided with a boss, and a retaining ring 103 is fixed above the boss. The retaining ring 103 cooperates with the boss to limit the vertical position of the connector 102.

[0037] Specifically, the bottom of piston rod 5 is provided with a plug 7, which is used to drive piston rod 5 and piston rod 6 to reset under external pressure.

[0038] Specifically, piston 601 can slide along the inner wall of the sliding cavity, and the outer diameter of piston 601 is matched with the inner diameter of the sliding cavity.

[0039] Specifically, the bottom of the cylinder 101 is provided with a limiting sleeve 105, which is used to limit the downward movement limit of the piston 501.

[0040] Specifically, the bottom of the cylinder body 101 is provided with a retaining ring 2 106, which is located below the limiting sleeve 105 and is used to fix the position of the limiting sleeve 105.

[0041] Specifically, the bottom of the sliding cavity is provided with a limiting sleeve 502, which is used to limit the downward movement limit position of the piston 601.

[0042] Specifically, the bottom of the sliding cavity is provided with a retaining ring 3 503, which is located below the limiting sleeve 2 502 and is used to fix the position of the limiting sleeve 2 502.

[0043] The process includes: the outlet 107 is connected to the spray pipe 3. When the upper mold 2 and the lower mold 4 are separated, the connecting sleeve 104 is inserted into the groove. The connector 102 is connected to the air source. When air is input into the cylinder 101 from the connector 102, the air passes through the connecting sleeve 104 and the connecting hole into the sliding cavity, creating a high-pressure environment in the sliding cavity. This drives the piston rod 6 to move downward along the sliding cavity until the piston 601 touches the limiting sleeve 502. Continuing to input air further drives the piston rod 5 to move downward along the receiving cavity until the piston 501 moves below the connector 8. At this point, the connector 8 cannot discharge air between the piston rod 5 and the inner wall of the cylinder 101. Lubricant is introduced into the gap, and piston 601 drives a predetermined amount of lubricant stored in the gap between piston rod 5 and the inner wall of cylinder 101 to be output outward through outlet 107; when piston 501 drives connecting sleeve 104 away from the groove and connector 8 is above piston 501, lubricant gradually enters the sliding cavity to lubricate the sliding cavity; when upper mold 2 and lower mold 4 are pressed together, upper mold 2 moves downward, causing the plug 7 to drive piston rod 6 upward under the pressure to squeeze back the excess lubricant, and drive piston rod 5 and piston rod 6 to reset, so that connecting sleeve 104 extends into the groove and piston 601 abuts against piston 501.

[0044] The system employs a two-stage linkage structure between piston rod 5 and piston rod 6. When piston 501 is positioned above, connector 8 inputs lubricant into the gap. Using air pressure, piston rod 6 first moves downwards to the limiting sleeve 502, then piston rod 5 moves downwards to below connector 8. This allows for precise output of lubricant pre-stored in the gap between piston rod 5 and the inner wall of cylinder 101, preventing waste or insufficient lubricant. When piston 501 moves connecting sleeve 104 away from the groove of connector 102 and connector 8 is positioned above piston 501, lubricant can pass through... The gap is immersed in the sliding cavity to automatically lubricate the mating surface between piston rod 2 6 and the sliding cavity; the movement limit positions of piston rod 1 5 and piston rod 2 6 are limited by limit sleeve 1 105 and limit sleeve 2 502 respectively, and the key components are fixed by retaining ring 1 103, retaining ring 2 106 and retaining ring 3 503 to limit the stroke during repeated movement. When the upper mold 2 and the lower mold 4 are pressed together, the sealing 7 drives piston rod 2 6 to move upward under the action of external pressure, which can squeeze the excess lubricant back to the storage area, and at the same time realize the synchronous reset of piston rod 1 5 and piston rod 2 6.
