[0002] When a static pressure machine processes and produces products, the object to be processed is placed in a processing chamber, and then a plug is driven to move by hydraulic pressure to seal the processing chamber. The pressure is gradually increased through a pressurization system, and the pressure is transmitted through a liquid, so that equal pressure is applied to each surface of the object for compression. After forming, the oil liquid inside the processing chamber is discharged for pressure relief. Finally, it is necessary to operate the hydraulic pressure to pull out the plug and then take out the formed workpiece. The side wall of the plug will carry oil liquid, and the oil liquid is easy to drip, so it is necessary to collect the oil liquid.

[0024] As Figures 1 - 5 shown, the present utility model provides the following technical solution: an oil liquid recovery mechanism for a hydraulic press, including the base 1 of the horizontal hydraulic press. The top surface of the base 1 of the horizontal hydraulic press is fixedly connected with the treatment chamber 4 through a locking member. The side walls of the base 1 of the horizontal hydraulic press are symmetrically and fixedly connected with hydraulic cylinders 2. The output end of the hydraulic cylinder 2 is fixedly connected with a plug 3 adapted to the treatment chamber 4. The bottom surface of the plug 3 is slidably connected with a collection chamber 5 through a reset assembly. The bottom end of the collection chamber 5 is fixedly communicated with a corrugated hose 9. The other end of the corrugated hose 9 is fixedly communicated with an oil return pipe. The collection chamber 5 can collect the oil liquid that slides down the side wall of the plug 3.

[0025] Please combine Figure 4As shown, during the use process, the workpiece to be compressed is placed into the processing chamber 4 along the side-end opening of the processing chamber 4. Then, the hydraulic mechanism is operated to make the output end of the hydraulic cylinder 2 start to work. The output end of the hydraulic cylinder 2 drives the plug 3 to move and gradually insert into the processing chamber 4 for sealing work. The plug 3 drives the collection chamber 5 to move gradually closer to the processing chamber 4 through the reset assembly and stop moving after it fits with the side wall of the processing chamber 4. At this time, the plug 3 continues to move to push the reset assembly to work. When the plug 3 is fully inserted into the processing chamber 4, it stops moving, as Figure 1 shown. Then, the oil fluid is injected into the processing chamber 4 through the delivery pipe by the high-pressure pump to compress the workpiece.

[0026] After the workpiece is compressed, the workpiece needs to be taken out. The hydraulic station is operated to make the hydraulic cylinder 2 start to work. The output end of the hydraulic cylinder 2 drives the plug 3 to move and gradually slide out of the processing chamber 4. At the beginning, the collection chamber 5 fits with the side wall of the processing chamber 4 and does not move. The plug 3 drives the reset assembly to gradually move for resetting. Before the reset assembly is fully reset, the plug 3 will continue to move after sliding out of the processing chamber 4. The plug 3 drives the collection chamber 5 to move along with the plug 3 through the reset assembly, thus realizing the collection of the oil fluid adhering to the side wall of the plug 3. There is no need to fix a collection chamber 5 with a length at least equal to the sliding path length of the plug 3 below the sliding path of the plug 3, increasing the operating space between the processing chamber 4 and the plug 3, facilitating the placement and taking out of the workpiece. The oil fluid entering the collection chamber 5 enters the return oil pipe along the corrugated hose 9.

[0027] The inner cross-section of the collection chamber 5 is trumpet-shaped and the opening is upward. Please combine with Figure 1 shown. During the use process, the oil fluid has a relatively high temperature, accelerating the falling speed of the oil fluid entering the collection chamber 5, thus accelerating the speed of the oil fluid entering the corrugated hose 9 and reducing the heat dissipation of the oil fluid.

[0028] The reset assembly includes a plurality of dovetail blocks 6. The dovetail blocks 6 are slidably arranged in dovetail grooves 7. The dovetail grooves 7 are opened on the top surface of the collection chamber 5. The top surface of the dovetail blocks 6 is fixedly connected to the bottom surface of the plug 3. A tension spring 8 is fixedly connected between the dovetail blocks 6 and the collection chamber 5. The tension spring 8 is arranged in the dovetail groove 7.

[0029] Please combine with Figure 4 shown. During the use process, the workpiece to be compressed is placed into the processing chamber 4 along the side-end opening of the processing chamber 4. Then, the hydraulic mechanism is operated to make the output end of the hydraulic cylinder 2 start to work. The output end of the hydraulic cylinder 2 drives the plug 3 to move and gradually insert into the processing chamber 4 for sealing work. The plug 3 drives the dovetail blocks 6 to move. The dovetail blocks 6 drive the tension spring 8 to move. The tension spring 8 drives the collection chamber 5 to move gradually closer to the side wall of the processing chamber 4 and stop moving after it fits with the side wall. At this time, the plug 3 continues to move and insert into the processing chamber 4. The plug 3 drives the dovetail blocks 6 to move and pull the tension spring 8 to deform. When the plug 3 is fully inserted into the processing chamber 4, it stops moving, asFigure 1 as shown

[0030] When it is necessary to take out the workpiece, operate the hydraulic mechanism so that the output end of the hydraulic cylinder 2 starts to work. The output end of the hydraulic cylinder 2 drives the plug 3 to move, the plug 3 drives the dovetail block 6 to move, and the movement of the dovetail block 6 causes the stretched spring 8 that is deformed at this time to gradually recover its deformation. At this time, the collection chamber 5 does not move. When the plug 3 completely slides out of the processing chamber 4, the side wall of the collection chamber 5 is still in contact with the side wall of the processing chamber 4. At this time, the plug 3 continues to move. When the deformation of the stretched spring 8 is completely restored, at this time, the plug 3 drives the dovetail block 6 to move, the dovetail block 6 drives the stretched spring 8 to move, and the stretched spring 8 drives the collection chamber 5 to move. At this time, the plane where the side wall of the plug 3 is located is above the collection chamber 5, and the collection chamber 5 realizes the collection of the oil fluid that slides off the side wall of the plug 3. After the oil fluid enters the collection chamber 5, it enters the return oil pipe along the corrugated hose 9 for the next use.

[0031] Two sliding rods 10 are slidably arranged through the top surface of the collection chamber 5. The plug 3 is arranged between the two sliding rods 10. A scraping plate 11 is fixedly connected between the tops of the opposite side walls of the two sliding rods 10. The scraping plate 11 can scrape off the oil fluid on the side wall of the plug 3. The bottom ends of the two sliding rods 10 pass through the sliding grooves 14 and penetrate into the positioning grooves 12 and are fixedly connected with a first sliding rod 15. The two sliding grooves 14 are opened on the top surface of the positioning block 13. The positioning block 13 is fixed in the positioning groove 12. The positioning groove 12 is opened on the top surface of the horizontal static press base 1. The top surface of the first sliding rod 15 is in sliding connection with the inclined surface of the positioning block 13 in a fitting manner.

[0032] Please refer to Figure 4 as shown, during the use process, when the plug 3 indirectly drives the collection chamber 5 to move horizontally, the collection chamber 5 drives the sliding rod 10 to move, the sliding rod 10 drives the first sliding rod 15 to slide in the positioning groove 12, the positioning groove 12 pushes the first sliding rod 15 to move upward, the first sliding rod 15 drives the scraping plate 11 to gradually move upward. When the collection chamber 5 is in contact with the side wall of the processing chamber 4, it means that the scraping plate 11 will slide off the side end of the plug 3 before. When the plug 3 is completely inserted into the processing chamber 4, it stops moving, as Figure 1 as shown

[0033] When the plug 3 is pulled out from the processing chamber 4, when the plug 3 can indirectly drive the collection chamber 5 to move, the collection chamber 5 drives the sliding rod 10 to move in the sliding groove 14, the sliding rod 10 drives the first sliding rod 15 to slide, the positioning block 13 pushes the first sliding rod 15 to move longitudinally, and the first sliding rod 15 drives the scraping plate 11 to gradually move downward through the sliding rod 10 to clean the side wall of the plug 3, and scrape off the oil fluid on the side wall of the plug 3 and let it fall into the collection chamber 5.

[0034] The longitudinal cross-sectional shape of the scraping plate 11 is an inverted triangle.

[0035] Please refer to Figure 2As shown, during use, the scraping plate 11 scrapes off the oil fluid on the side wall of the plug 3, and the oil fluid slides down along the inclined surface of the scraping plate 11 into the collection cavity 5, achieving the aggregation of the sliding oil fluid and reducing the splashing of the oil fluid to the outside.

[0036] The length of the first sliding rod 15 is less than the width of the positioning groove 12.

[0037] Please refer to Figure 2 As shown, during use, the contact area between the first sliding rod 15 and the surface of the base 1 of the horizontal hydraulic press is reduced, thereby reducing the frictional force between the first sliding rod 15 and the base 1 of the horizontal hydraulic press and facilitating the sliding of the first sliding rod 15.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
