Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, specifically to a hydraulic press that is easy to cool. Background Technology

[0002] A hydraulic press (a type of hydraulic press) is a machine that uses specialized hydraulic oil as its working medium and a hydraulic pump as its power source. The pump forces the hydraulic oil through hydraulic lines into a cylinder. Inside the cylinder are several sets of interlocking seals, each with different seals at different locations, all serving the same purpose: preventing hydraulic oil leakage. Finally, a check valve circulates the hydraulic oil in a tank, causing the cylinder to perform work and thus complete a specific mechanical action. Hydraulic presses are commonly used for die stamping and forming operations.

[0003] However, existing hydraulic presses do not have a cooling effect, so they cannot quickly cool down the stamped workpieces, making demolding inconvenient and making it difficult to manually remove the workpieces, thus affecting the applicability of the equipment.

[0004] To address this issue, we propose a hydraulic press that is easy to cool. Utility Model Content

[0029] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0030] Example 1

[0031] like Figure 1-5 As shown, this utility model provides a technical solution: a hydraulic press that is easy to cool, including a support platform 1, a mounting bracket 2 fixedly installed on the upper part of the support platform 1, a coolant tank 4 fixedly installed at the bottom of the support platform 1, a feed pump 5 fixedly installed on the left side of the coolant tank 4 via a support, a hydraulic pump 6 fixedly installed on the upper part of the mounting bracket 2, an upper mold 7 fixedly connected to the output end of the hydraulic pump 6, a lower mold 8 fixedly installed on the upper part of the support platform 1, and a connecting assembly 3 disposed on one side of the support platform 1. The connecting assembly 3 includes a cooling mechanism 31 disposed on the lower part of the support platform 1. A stirring mechanism 32 is disposed inside the coolant tank 4. The input end of the feed pump 5 is connected to the coolant tank 4 via an absorption pipe. The cooling mechanism 31 includes components fixedly installed in the coolant tank. 4. The filter box 311 on the left has an installation groove 312 inside. An installation frame 313 is inserted into the installation groove 312. A filter plate 314 is fixedly connected inside the installation frame 313. A sliding groove 315 is opened at the front of the filter box 311. A sliding rod 316 is fixedly connected to the inner wall of the sliding groove 315. A slider 317 is slidably connected to the outer wall of the sliding rod 316. A first spring 318 is fixedly connected to the inner wall of the sliding groove 315. A limit rod 319 is fixedly connected to the outer side of the slider 317. An annular cooling groove 3111 is opened inside the lower mold 8. An inlet pipe 3110 is connected to the left side of the annular cooling groove 3111. A sealing ring is fixedly connected to the inner wall of the filter box 311, and the sealing ring is located in the gap between the filter box 311 and the installation frame 313.

[0032] In this embodiment, one end of the first spring 318 is fixedly connected to the slider 317, the inner side of the limiting rod 319 is fitted to the outer side of the mounting frame 313, and the bottom of the filter box 311 is connected to the output end of the feed pump 5 through the discharge pipe. Through the cooperation of the filter box 311, mounting groove 312, mounting frame 313, filter plate 314, sliding groove 315, sliding rod 316, slider 317, first spring 318, limiting rod 319, liquid inlet pipe 3110, annular cooling tank 3111, and connecting hole 3112, the coolant can be circulated through the lower mold 8, thereby cooling the stamped workpiece and making it easier to demold and remove the material in the subsequent operation. The coolant entering the annular cooling tank 3111 can also be filtered to prevent the coolant from adhering to the annular cooling tank 3111 and causing blockage, which would affect subsequent use.

[0033] Furthermore, the bottom end of the liquid inlet pipe 3110 is connected to the upper part of the filter box 311. There are three annular cooling tanks 3111, and a connection hole 3112 is provided between two adjacent annular cooling tanks 3111. The coolant tank 4 is connected to the lower annular cooling tank 3111 through a connecting pipe.

[0034] When the device is in use, after the workpiece is stamped, the coolant in the coolant tank 4 is transported into the filter box 311 by the feed pump 5, and then transported into the annular cooling tank 3111 through the liquid inlet pipe 3110. Under the action of the connecting hole 3112, the coolant can circulate through the lower mold 8 and finally flow into the coolant tank 4, thereby cooling the stamped workpiece and making it easier to demold and remove the material. When the coolant passes through the filter box 311, it can be filtered by the filter plate 314. Furthermore, when it is necessary to disassemble the mounting frame 313, simply push the limiting rod 319 upward by hand. Under the limiting action of the sliding rod 316 and the slider 317, the limiting rod 319 fixed to the outside of the slider 317 can be moved away from the outside of the mounting frame 313. Then the mounting frame 313 can be taken out, and the filter plate 314 can be cleaned, which facilitates subsequent use.

[0035] Example 2

[0036] Based on Embodiment 1, a preferred embodiment of the hydraulic press provided by this utility model that facilitates cooling is, for example... Figures 1 to 5 As shown: The stirring mechanism 32 includes a cooler 321 fixedly installed on the side of the coolant tank 4. The output end of the cooler 321 is electrically connected to a cooling pipe 322. A motor 323 is fixedly installed at the bottom of the coolant tank 4 via a bracket. A first rotating shaft 324 is fixedly connected to the output end of the motor 323. A stirring rod 325 is fixedly connected to the outer wall of the first rotating shaft 324. A rotating rod 326 is fixedly connected to the outer wall of the first rotating shaft 324. A second rotating shaft 327 is rotatably connected to one end of the rotating rod 326 via a bearing. A conveying blade 328 is fixedly connected to the outer wall of the second rotating shaft 327. A gear 329 is fixedly connected to the bottom end of the second rotating shaft 327. A gear ring 3210 is fixedly installed at the bottom of the inner wall of the coolant tank 4 via a mounting column.

[0037] In this embodiment, the first rotating shaft 324 is rotatably connected to the coolant tank 4 via a bearing, and one end of the refrigeration pipe 322 is electrically connected to the input end of the refrigeration pipe 322. Through the cooperation of the cooler 321, refrigeration pipe 322, motor 323, first rotating shaft 324, stirring rod 325, rotating rod 326, second rotating shaft 327, conveying blade 328, gear 329, and gear ring 3210, the coolant in the coolant tank 4 can be cooled and stirred, thus facilitating subsequent recycling.

[0038] Furthermore, gear 329 is engaged with gear ring 3210.

[0039] When cooling is required, the coolant in the coolant tank 4 is cooled by the cooperation of the cooler 321 and the cooling pipe 322. The motor 323 drives the first rotating shaft 324 to rotate, which causes the stirring rod 325 fixedly connected to the outer wall of the first rotating shaft 324 to rotate synchronously, thus stirring the coolant in the coolant tank 4. This improves the contact between the coolant and the cooling pipe 322, resulting in better cooling. Furthermore, when the first rotating shaft 324 rotates, the rotating rod 326 fixedly connected to the outer wall of the first rotating shaft 324 drives the second rotating shaft 327 to rotate synchronously. Since the gear 329 and the gear ring 3210 are meshed, the conveying blade 328 fixedly connected to the outer wall of the second rotating shaft 327 rotates on its own axis while revolving around the central axis, thus conveying the material at the bottom of the coolant tank 4 upwards and preventing coolant accumulation at the bottom, which would affect the cooling effect.
