Description

Technical Field

[0001] This utility model relates to the field of screw press technology, and in particular to an automatically lubricated screw press. Background Technology

[0002] A screw press is a forging device that converts rotary motion into linear pressure through screw transmission. It is widely used in metal forming, refractory material manufacturing and other fields.

[0003] The screw press drives a large-diameter flywheel to rotate via a servo motor and gear set. The flywheel drives the screw to rotate, thereby raising and lowering the forging hammer. During this process, mechanical transmission generates wear and heat, which generally requires a lubrication system to lubricate the mechanical structure.

[0004] For example, patent document CN216309654U discloses an automatically lubricated pressure testing press, including a base, an automatic lubrication structure, and a protective structure. Guide posts are installed at the four corners of the base's top, and an upper crossbeam is installed on the top surface of each guide post. A sliding crossbeam is fitted onto the surface of each guide post, and the automatic lubrication structure is installed inside the sliding crossbeam. The protective structure is installed inside the base. This invention incorporates an automatic lubrication structure, an automatic oil injector, a flexible oil guide tube, a safety sleeve, an oil outlet, and an oil seal. The automatic oil injector delivers lubricating oil through the flexible oil guide tube into the safety sleeve from the oil outlet. The lubricating oil lubricates the guide posts within the safety sleeve, while the oil seal prevents lubricating oil leakage from the joint between the safety sleeve and the guide posts. This reduces wear caused by relative sliding between the sliding crossbeam and the guide posts, thereby increasing the press's service life and eliminating the need for tedious manual lubrication.

[0005] In existing technologies, lubricating oil is generally delivered into the press drive structure through an external lubricating oil pump station to achieve a lubrication effect. However, since the pump station can only pump lubricating oil in accordance with the working status of the press by sensing the working status of the press through sensors and an electronic control system, the sensors and electronic control systems used in this process have high manufacturing and usage costs, and their reliability is insufficient in the press usage scenario, requiring frequent maintenance.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-7 As shown, an automatically lubricated screw press includes a main body, which includes a lifting hammer 105. A drive mechanism is mounted on the top of the main body, and the drive mechanism includes a closed housing 204. A brake mechanism is mounted on the top of the drive mechanism. An automatic lubrication mechanism is mounted on the main body, and the automatic lubrication mechanism includes an oil tank 305. A filter assembly 304 is connected to one side of the oil tank 305 via a pipe. The filter assembly 304 is prior art, and its specific structure will not be described here. A reverse-flowing... The plunger cylinder 306 is a T-shaped plunger cylinder. One-way valves 307 are fixedly connected to both ends of the plunger cylinder 306. One side of the plunger cylinder 306 is connected to the oil tank 305 via a pipe, and the other side is fixedly connected to an oil inlet pipe 301. The other end of the oil inlet pipe 301 is fixedly connected to a sealed housing 204, and an oil spray nozzle 302 is fixedly connected to the other end of the oil inlet pipe 301. A return oil pipe 303 is fixedly connected to the bottom of the other side of the sealed housing 204, and the other end of the return oil pipe 303 is connected to a filter assembly 304. The inner seal sliding connection 06 has a piston rod 308, which is fixedly connected to the lifting hammer 105. During use, the drive mechanism drives the lifting hammer 105 to reciprocate, applying pressure to the workpiece. The braking mechanism ensures smooth switching between forward and reverse rotation of the rotating screw 107, preventing excessive inertia from damaging the drive mechanism. While the lifting hammer 105 is rising and falling, it also drives the piston rod 308 to rise and fall synchronously. The piston rod 308 slides relative to the plunger cylinder 306, thus increasing the internal space of the plunger cylinder 306. Lubricating oil is drawn into the oil tank 305, and then the internal space of the plunger cylinder 306 decreases, pumping the internal lubricating oil into the oil inlet pipe 301. Two one-way valves 307 ensure smooth pumping. The lubricating oil is sprayed from the oil inlet pipe 301 into the closed housing 204 through the oil spray nozzle 302, thus ensuring smooth transmission. After lubrication, the lubricating oil flows back from the oil return pipe 303 to the filter assembly 304, where it is purified before entering the oil tank 305 to await the next cycle.

[0020] The main body of the device also includes a base 101. An upper support 102 is fixedly connected to the top of the base 101. Vertically arranged slide rails 104 are fixedly connected to the left and right sides of the upper support 102. The slide rails 104 are slidably connected to the lifting hammer 105. A rotating screw 107 is rotatably connected to the top of the upper support 102. The rotating screw 107 is threadedly connected to the lifting hammer 105. In use, the rotating screw 107 rotates to drive the lifting hammer 105 to rise and fall. During the sliding process, the sliding direction of the lifting hammer 105 is kept stable by the slide rails 104.

[0021] A lower mold support platform 103 is fixedly connected to the base 101, and an upper mold support platform 106 is fixedly connected to the bottom of the lifting hammer 105. The lower mold support platform 103 and the upper mold support platform 106 are set in correspondence. When in use, the lifting hammer 105 drives the upper mold support platform 106 to rise and fall. The upper mold support platform 106 and the lower mold support platform 103 cooperate to achieve the pressing and forming of the workpiece.

[0022] The drive mechanism also includes a large gear 203 fixedly connected to the rotating screw 107. The large gear 203 is rotatably connected to the enclosed housing 204. A servo motor 201 is fixedly connected to one side of the top of the enclosed housing 204. A small gear 202 is fixedly connected to the output end of the servo motor 201. The small gear 202 meshes with the large gear 203. An oil spray nozzle 302 is positioned above the meshing position of the small gear 202 and the large gear 203. The bottom surface inside the enclosed housing 204 is set as an inclined surface that tends towards the return oil pipe 303. In use, the servo motor 201 drives the small gear 202 to rotate, the small gear 202 drives the large gear 203 to rotate, and the large gear 203 drives the rotating screw 107 to rotate. Lubricating oil is sprayed onto the meshing position of the small gear 202 and the large gear 203, thereby ensuring stable transmission between the small gear 202 and the large gear 203. The lubricated oil flows to the return oil pipe 303 under the guidance of the bottom inclined surface.

[0023] A brake disc 401 is fixedly connected to the top of the rotating screw 107. Two symmetrically arranged cylinders 402 are fixedly connected to the top of the upper bracket 102. A friction plate 403 is fixedly connected to the output end of the cylinder 402. The friction plate 403 can abut against the side of the brake disc 401. In use, the brake disc 401 rotates with the rotating screw 107. When it is necessary to stop the rotating screw 107, the cylinder 402 drives the friction plate 403 to abut against the side of the brake disc 401, and stops the rotation of the brake disc 401 by friction. Thus, the rotating screw 107 stops rotating synchronously.

[0024] Working principle: Servo motor 201 drives pinion 202 to rotate, pinion 202 drives large gear 203 to rotate, large gear 203 drives rotating screw 107 to rotate, rotating screw 107 drives lifting hammer 105 to rise and fall. During the sliding process, lifting hammer 105 is kept stable by slide rail 104. Lifting hammer 105 drives upper mold support platform 106 to rise and fall. Upper mold support platform 106 and lower mold support platform 103 cooperate to press and form the workpiece. Brake disc 401 rotates with rotating screw 107. When rotating screw 107 needs to stop rotating, cylinder 402 drives friction plate 403 to abut against the side of brake disc 401, stopping the rotation of brake disc 401 through friction. Thus, rotating screw 107 stops rotating synchronously, and lifting hammer 105 rises and falls. Simultaneously, the lifting hammer 105 drives the piston column 308 to rise and fall synchronously. The piston column 308 slides relative to the plunger cylinder 306, thus increasing the internal space of the plunger cylinder 306 to draw in the lubricating oil from the oil tank 305. Subsequently, the internal space of the plunger cylinder 306 decreases, pumping the internal lubricating oil into the oil inlet pipe 301. Two one-way valves 307 ensure smooth pumping. The lubricating oil is sprayed onto the meshing position of the pinion 202 and the large gear 203, thereby ensuring stable transmission between the pinion 202 and the large gear 203 and smooth transmission. The lubricated oil flows to the return oil pipe 303 under the guidance of the bottom inclined surface. The lubricating oil flows back from the return oil pipe 303 to the filter assembly 304, where it is purified before entering the oil tank 305 to await the next cycle.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
