A hydraulic press column structure

Abstract

This utility model discloses a hydraulic press column structure, belonging to the field of hydraulic press technology. It includes a hydraulic press and a support column arranged on the hydraulic press for supporting it. An oil receiving structure arranged on the support column is used to collect lubricating oil sliding down from the support column. A retaining structure arranged on the oil receiving structure is used to increase the capacity of the oil receiving structure. In this utility model, during lubrication of the support column, excess lubricating oil flows downwards along the surface of the support column. By installing a telescopic tube and a threaded sleeve below the support column, the flowing lubricating oil can be collected, preventing it from flowing onto the processing table of the hydraulic press and causing contamination. It also facilitates the recycling of excess lubricating oil. A sealing ring increases the sealing between the threaded sleeve and the support column. If a small amount of lubricating oil leaks from the sealing ring and the support column, it can be absorbed by the threaded sleeve below, further preventing lubricating oil from falling onto the hydraulic press.

Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, specifically to a hydraulic press column structure. Background Technology

[0002] The column is an important supporting component of the hydraulic press frame, supporting the upper crossbeam and the worktable (lower crossbeam), ensuring the stability and rigidity of the frame. The column also serves as a guide for the movement of the movable crossbeam. During the pressing and return processes of the hydraulic press, the movable crossbeam needs to move up and down along the column. The guide sleeve of the column ensures the straightness of the movable crossbeam during movement, thereby improving the processing accuracy and stability of the hydraulic press.

[0003] In the prior art, when lubricating the column of a hydraulic press, it is usually necessary to apply lubricating oil to the surface of the column. However, during the application process, excessive application may result in excess oil. The excess lubricating oil will flow down the surface of the column and eventually flow onto the hydraulic equipment, causing contamination of the surface of the hydraulic equipment and making the working environment greasy. Utility Model Content

[0004] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a hydraulic press column structure that solves the problem in the background art where excess lubricating oil flows down the column surface onto the hydraulic equipment during lubrication, causing contamination of the equipment surface.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A hydraulic press column structure, comprising:

[0007] Hydraulic press;

[0008] Support columns, arranged on the hydraulic press, are used to support the hydraulic press;

[0009] An oil receiving structure is arranged on the support column to collect lubricating oil that slides down from the support column;

[0010] The enclosure structure is placed on the oil receiving structure to increase the capacity of the oil receiving structure;

[0011] An adjustment structure, placed on the enclosure structure, is used to control the expansion and contraction of the enclosure structure;

[0012] The adjustment structure includes multiple sets of lifting components that control the raising and lowering of the enclosure structure, and a linkage component for controlling the simultaneous operation of the multiple sets of lifting components.

[0013] Preferably, the oil receiving structure includes:

[0014] The threaded seat is fixedly sleeved on the support column;

[0015] A threaded sleeve, with threads fitted onto a threaded seat;

[0016] A tapered guide plate is arranged inside the threaded sleeve;

[0017] The oil outlet pipe is located on the outer surface of the threaded sleeve and is connected to the threaded sleeve.

[0018] One end of the oil outlet pipe is equipped with a sealing cap, which is threadedly connected to the oil outlet pipe.

[0019] Preferably, a sealing ring is arranged on the tapered guide plate.

[0020] Preferably, the oil-receiving structure further includes oil-absorbing cotton, which is located below the conical guide plate and consists of two semi-circular rings for absorbing leaked lubricating oil. The oil-absorbing cotton is in contact with the surface of the supporting column.

[0021] Preferably, the enclosure structure includes:

[0022] The telescopic tube is positioned above the threaded sleeve;

[0023] A ring frame is placed at one end of the telescopic tube.

[0024] Preferably, the lifting assembly includes:

[0025] A fixing plate is placed on a circular frame;

[0026] The screw is located below the fixed plate;

[0027] The linkage gear ring is threaded onto the screw.

[0028] Preferably, the outer surface of the threaded sleeve is provided with a fixing frame and a limiting frame, and the linkage gear ring is rotatably installed between the fixing frame and the limiting frame.

[0029] Preferably, the lifting assembly further includes:

[0030] Two annular grooves are respectively formed inside the fixed frame and the limiting frame;

[0031] Two limiting rings are respectively arranged on both sides of the linkage gear ring, and the two limiting rings are rotatably installed inside the two annular grooves.

[0032] Preferably, the linkage component includes:

[0033] The linkage gear ring is rotatably sleeved on the threaded sleeve, and the linkage gear ring meshes with the linkage gear ring.

[0034] Preferably, the linkage assembly further includes a fixing ring fixedly sleeved on the threaded sleeve, the fixing ring being rotatably installed inside the linkage gear ring to limit the rotational position of the linkage gear ring.

[0035] The beneficial effects of this utility model are as follows:

[0036] In this invention, when lubricating the support column, excess lubricating oil will flow downwards along the surface of the support column. By installing a telescopic tube and a threaded sleeve at the bottom of the support column, the flowing lubricating oil can be collected, preventing the lubricating oil from flowing onto the processing table of the hydraulic press and causing pollution. At the same time, it is convenient to recycle and reuse the excess lubricating oil.

[0037] This invention increases the sealing between the threaded sleeve and the support column by setting a sealing ring. If a small amount of lubricating oil leaks from the sealing ring and the support column, it can be absorbed by the threaded sleeve set below, further preventing the lubricating oil from falling onto the hydraulic press.

[0038] This invention increases the capacity of the threaded sleeve to collect lubricating oil by setting a telescopic tube. The telescopic tube can be raised and lowered by rotating the linkage gear ring, and can be extended or retracted. When the telescopic tube is extended, it can collect more lubricating oil, and when it is retracted, it can reduce the space it occupies and avoid interfering with the operation of the crossbeam on the hydraulic press.

[0048] 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.

[0049] Example 1:

[0050] like Figures 1 to 6 As shown, this utility model provides a hydraulic press column structure, including: a hydraulic press 1 and a support column 101 arranged on the hydraulic press 1 for supporting the hydraulic press 1, an oil receiving structure arranged on the support column 101 for receiving lubricating oil sliding down from the support column 101, and a enclosure structure arranged on the oil receiving structure for increasing the capacity of the oil receiving structure.

[0051] The oil receiving structure includes a threaded seat 2 fixedly sleeved on the support column 101, a threaded sleeve 201 threaded on the threaded seat 2, a tapered guide plate 202 arranged inside the threaded sleeve 201, an oil outlet pipe 203 arranged on the outer surface of the threaded sleeve 201 and connected to the threaded sleeve 201, a sealing cap 204 threaded on one end of the oil outlet pipe 203, a sealing ring 206 arranged on the tapered guide plate 202, and an oil-absorbing cotton 205 that fits against the surface of the support column 101. When the support column 101 is lubricated, excess lubricating oil will flow downward along the surface of the support column 101, allowing the lubricating oil to fall onto the tapered guide plate 202 inside the threaded sleeve 201 through the telescopic pipe 3. The sealing performance between the tapered guide plate 202 and the support column 101 can be increased by setting the sealing ring 206.

[0052] The oil receiving structure also includes an oil-absorbing cotton 205 located below the conical guide plate 202 to absorb leaked lubricating oil. The oil-absorbing cotton 205 consists of two semi-circular rings. If a small amount of lubricating oil seeps down through the gap between the sealing ring 206 and the support column 101, it will be absorbed by the oil-absorbing cotton 205 located below.

[0053] The enclosure structure includes a telescopic pipe 3 arranged above the threaded sleeve 201 and an annular frame 301 arranged at one end of the telescopic pipe 3. The telescopic pipe 3 can be used to increase the capacity of the threaded sleeve 201 to receive lubricating oil.

[0054] Example 2:

[0055] Based on Example 1, in order to further increase the capacity of receiving lubricating oil and facilitate the adjustment of capacity according to usage requirements, an adjustment structure for controlling the expansion and contraction of the enclosure structure is arranged on the enclosure structure. The adjustment structure includes multiple sets of lifting components for controlling the lifting and moving of the enclosure structure.

[0056] The lifting assembly includes a fixed plate 4 arranged on the annular frame 301, a screw 401 arranged below the fixed plate 4, a linkage gear ring 402 threaded onto the screw 401, a fixed frame 403 and a limiting frame 404 arranged on the outer surface of the threaded sleeve 201, the linkage gear ring 402 being rotatably installed between the fixed frame 403 and the limiting frame 404, and the lifting assembly also includes two annular grooves 405 respectively opened inside the fixed frame 403 and the limiting frame 404, and two limiting rings 406 respectively arranged on both sides of the linkage gear ring 402, the two limiting rings 406 being rotatably installed inside the two annular grooves 405;

[0057] When the linkage gear ring 402 rotates, it can drive the screw 401 to move up and down through the threaded engagement with the screw 401, so that the screw 401 drives the ring frame 301 to move up and down, and in turn drives the telescopic tube 3 to move up and down.

[0058] The rotating linkage gear ring 402 can drive the limiting rings 406 on both sides to rotate in the corresponding annular grooves 405. The position of the linkage gear ring 402 during rotation can be restricted by the setting of the annular grooves 405 and the limiting rings 406, so as to prevent it from deviating.

[0059] Example 3:

[0060] Based on Embodiment 2, in order to coordinate and control multiple sets of lifting components, the adjustment structure also includes a linkage component for controlling multiple sets of lifting components;

[0061] Specifically, the linkage component includes a linkage gear ring 407 rotatably sleeved on the threaded sleeve 201 for transmission. The linkage gear ring 407 meshes with the linkage gear ring 402. By rotating the linkage gear ring 407, it can simultaneously drive multiple linkage gear rings 402 to rotate through meshing with them.

[0062] The linkage assembly also includes a fixing ring 408 fixedly sleeved on the threaded sleeve 201 to limit the rotation position of the linkage gear ring 407. The fixing ring 408 is rotatably installed inside the linkage gear ring 407. When the linkage gear ring 407 rotates, it will rotate on the fixing ring 408. The fixing ring 408 is used to limit the rotation position of the linkage gear ring 407 and prevent the linkage gear ring 407 from deviating.

[0063] Working principle:

[0064] When lubricating the support column 101, excess lubricating oil flows downwards along the surface of the support column 101, allowing the lubricating oil to fall through the telescopic tube 3 onto the tapered guide plate 202 inside the threaded sleeve 201. The sealing ring 206 increases the seal between the tapered guide plate 202 and the support column 101. If a small amount of lubricating oil seeps down through the gap between the sealing ring 206 and the support column 101, it will be absorbed by the oil-absorbing cotton 205 below. The collected lubricating oil will flow outwards under the guidance of the inclined surface of the tapered guide plate 202. The oil outlet pipe 203 can be opened by rotating the sealing cap 204 to discharge the collected lubricating oil. The telescopic tube 3 can also increase the amount of lubricating oil collected by the threaded sleeve 201. The oil volume is controlled by rotating the linkage gear ring 407, which meshes with the linkage gear ring 402, causing the linkage gear ring 402 to rotate. The linkage gear ring 407 itself rotates on the fixed ring 408, and the rotating linkage gear ring 402 can drive the limit rings 406 on both sides to rotate in the corresponding annular grooves 405. The continuously rotating linkage gear ring 402 can drive the screw 401 to move up and down through the threaded engagement with the screw 401, so that the screw 401 drives the annular frame 301 to move up and down, and in turn drives the telescopic tube 3 to move up and down. When the telescopic tube 3 rises and unfolds, it can further increase the capacity to receive lubricating oil, and when the telescopic tube 3 descends and retracts, it can reduce its area and avoid interfering with the lifting and lowering operation of the crossbeam on the hydraulic press 1.

[0065] If the oil-absorbing cotton 205 absorbs too much lubricating oil, the oil-absorbing cotton 205 can be exposed by rotating the threaded sleeve 201 and unscrewing it from the threaded seat 2. The oil-absorbing cotton 205 consists of two separate semi-circular rings, which makes it easy to remove it from the support column 101 so as to recover the lubricating oil absorbed by the oil-absorbing cotton 205.

[0066] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
