Description

Technical Field

[0001] This utility model relates to the field of screw press technology, specifically to a screw press flywheel kinetic energy recovery device. Background Technology

[0002] Existing screw presses store a huge amount of rotational kinetic energy in their flywheels during operation. This energy is not completely exhausted after the impact is completed. The flywheel usually continues to rotate at a certain speed. This remaining kinetic energy is mainly dissipated as heat through air friction and bearing friction, resulting in energy waste. Utility Model Content

Especially in situations requiring rapid and continuous impact, this effectively improves the production cycle and overall capacity of the equipment, and solves the problems in the prior art.

[0017] 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.

[0018] To address the issue that existing screw presses store significant rotational kinetic energy in their flywheels during operation, and this energy is not completely dissipated after impact (the flywheel typically continues to rotate at a certain speed), this remaining kinetic energy is primarily dissipated as heat through air friction and bearing friction, resulting in energy waste; please refer to... Figs. 1-2 The present invention provides the following solution:

[0019] A flywheel kinetic energy recovery device for a screw press includes a workbench 1, a sliding sleeve 101 on the inner side of the workbench 1, a stamping plate 102 on the upper side of the sliding sleeve 101, wherein the stamping plate 102 is slidably connected to the sliding sleeve 101, a hydraulic assembly 2 on the upper side of the stamping plate 102, a drive handle 3 on the outer side of the hydraulic assembly 2, and a central shaft motor 201 at the bottom of the hydraulic assembly 2. The central shaft motor 201 includes a flywheel assembly 204, wherein a pressure rod 202 is provided below the flywheel assembly 204, and the pressure rod 202 is rotatably connected to the central shaft motor 201 through the flywheel assembly 204.

[0020] In this embodiment, after the screw press completes the striking action on the workpiece, the flywheel assembly 204 continues to rotate at a high speed due to inertia, storing considerable residual kinetic energy. At this time, the power input of the central shaft motor 201 has stopped or weakened, and the flywheel enters the free rotation deceleration stage. The pressure rod 202, which is rigidly connected to the flywheel assembly 204, is driven by the residual kinetic energy of the flywheel. When the residual kinetic energy of the flywheel drives the pressure rod 202 to produce a displacement relative to the support plate 4, the tension spring 203 connected between the two is stretched or compressed, storing part of the elastic potential energy. More importantly, the movement of the pressure rod 202, through its connection with the bottom of the hydraulic assembly 2, pushes the piston or plunger inside the hydraulic assembly. The hydraulic oil inside the hydraulic assembly 2 is pressurized and pumped out under the push of the piston. The high-pressure oil flow enters the valve group system composed of the horizontal valve chamber 401 and the vertical valve chamber 402 set inside the support plate 4 through the through connecting pipeline.

[0021] A support plate 4 is provided above the hydraulic component 2. The support plate 4 is connected to the workbench frame 1 by bolts. A horizontal valve chamber 401 is provided inside the support plate 4. A vertical valve chamber 402 is provided above the horizontal valve chamber 401. A spring valve core is provided at one end of the vertical valve chamber 402 and the horizontal valve chamber 401. The other end of the vertical valve chamber 402 and the horizontal valve chamber 401 are connected to the hydraulic component 2. The drive handle 3 includes a connecting rod 301, a telescopic sleeve shaft 302 and a support rod 303. The connecting rod 301 is rotatably connected to the support plate 4 through the support rod 303. The telescopic sleeve shaft 302 is connected to the vertical valve chamber 402. A piston rod is provided inside the telescopic sleeve shaft 302. The piston rod is connected to the connecting rod 301 by internal thread. Tension springs 203 are provided around the pressure rod 202. The tension springs 203 are connected to the support plate 4 by a locking buckle.

[0022] In this embodiment, during the process of the flywheel's remaining kinetic energy driving the pressure rod 202 to push the hydraulic oil, the valve core opens a specific passage under pressure, guiding the high-pressure oil to an external hydraulic accumulator. The high-pressure oil is stored in the accumulator, converting the flywheel's rotational kinetic energy into hydraulic potential energy. The operator can precisely adjust the valve core opening or switch the oil circuit direction through the handle 3, thereby controlling the flow rate and pressure of the hydraulic oil flowing into the accumulator, and even deciding when to store energy and when to release energy. The energy stored in the hydraulic accumulator is not idle. When the screw press needs to perform the preparatory action for the next strike, or when it needs to assist in driving the flywheel to accelerate, the system can work in reverse. By operating the drive handle 3 to adjust the valve core position, the return oil passage from the accumulator to the hydraulic component 2 is opened. When the high-pressure oil is released, it drives the piston / plunger in the hydraulic assembly 2 to move in the opposite direction. The movement of the piston / plunger at the bottom of the hydraulic assembly 2 drives the flywheel assembly 204 to accelerate rotation via the central shaft motor 201, or lifts the pressure rod 202 to reset. At this time, the tension spring 203 assists in the reset and may release its stored elastic potential energy. In this way, the previously stored hydraulic energy is converted into the rotational kinetic energy of the flywheel or the potential energy of the mechanism, which helps to complete the return stroke and significantly reduces the energy required by the central shaft motor 201 during the reset or acceleration phase.
