Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a four-column hydraulic press for processing garbage cans. Background Technology

[0002] A four-column hydraulic press is an important piece of machinery that uses the static pressure of hydraulic oil delivered by an oil pump to process products made of metal, plastic, rubber, wood, powder, and other materials. This equipment adopts a four-column, three-platen structure, featuring structural stability, a spacious working space, and good processability. Its working principle is based on Pascal's Law, achieving energy conversion and transfer through fluid pressure transmission. The four-column hydraulic press has an independent power mechanism and electrical system, offering flexible and convenient operation, and can achieve various working modes including adjustment, manual, and semi-automatic. It is widely used in the pressure processing and forming processes of various plastic materials, such as the cold pressing of metal parts and the pressing of powder products, making it an indispensable piece of equipment in industrial production.

[0003] In the manufacturing process of trash cans, a four-column hydraulic press plays a crucial role. This mechanical device efficiently utilizes the static pressure of hydraulic oil to press raw materials of different materials into shape. However, due to variations in the size, shape, and thickness of the raw materials used in trash can production, the hydraulically formed products may not perfectly meet the expected size and shape requirements. This typically means that workers must manually move the hydraulically formed trash cans to a cutting machine for a correction and cutting process. This process is not only time-consuming and labor-intensive, increasing labor costs, but also impacts overall production efficiency. Utility Model Content

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Please see Figure 1-9 This utility model provides a technical solution:

[0025] A four-column hydraulic press for processing trash cans includes a frame assembly 1, and a mold and a cutting assembly 2 are provided inside the frame assembly 1.

[0026] The frame assembly 1 includes a top plate 12. A hydraulic cylinder 11 is fixedly installed in the upper center of the top plate 12. Sliding columns 13 are fixedly connected to the four lower corners of the top plate 12. A hydraulic shaft 15 is installed below the hydraulic cylinder 11. A lifting plate 14 is fixedly connected below the hydraulic shaft 15. The lifting plate 14 has holes 141 at its four corners for the sliding columns 13 to move up and down. An operating box 16 is fixedly connected to the bottom of the sliding columns 13. A hydraulic oil pipe 17 is installed on the hydraulic cylinder 11. An operating panel 161 is provided in front of the operating box 16. A hydraulic oil tank 162 is installed on the bottom plate of the operating box 16. The hydraulic oil tank 162 is fixedly connected to a hydraulic motor 163. One end of the hydraulic oil pipe 17 is inserted into the hydraulic oil tank 162. The operation of the four-column hydraulic press can be fully controlled through the operating panel 161. The hydraulic motor 163 draws hydraulic oil from the hydraulic oil tank 162 through the hydraulic oil pipe 17 and injects this hydraulic oil into the hydraulic cylinder 11. As the amount of oil in the hydraulic cylinder 11 increases, the hydraulic shaft 15 will be lowered by pressure, thereby driving the lifting plate 14 to descend smoothly along the sliding column 13.

[0027] The mold and cutting assembly 2 includes a pressing head 21, which is fixedly connected to a lifting plate 14. A bottom mold 22 is located directly below the pressing head 21 and is fixedly connected to an operating box 16. The bottom of the pressing head 21 has a groove 211 that matches the bottom mold 22. A movable cutting assembly 23 is located on the right side of the bottom mold 22. The movable cutting assembly 23 includes a support plate 231, which is fixedly connected to the operating box 16. A movable assembly 232 is fixedly connected to the top left side of the support plate 231, and a rotating assembly 233 is located below the movable assembly 232. When the lifting plate 14 moves down, it drives the pressing head 21 to descend synchronously. When the pressing head 21 comes into contact with the raw material of the garbage can, it continues to press down until the groove 211 on it is tightly combined with the bottom mold 22 below, forming the garbage can.

[0028] The moving component 232 includes a first housing 2321. A first motor 2322 is fixedly mounted on the base plate of the first housing 2321. The output end of the first motor 2322 is fixedly connected to a lead screw 2323. The other end of the lead screw 2323 is connected to the rear plate of the first housing 2321 via a bearing. A lead screw nut 2324 is fitted onto the lead screw 2323. A rotating component 233 is fixedly connected below the lead screw nut 2324. The base plate of the first housing 2321 has a moving groove 2325 for the lead screw nut 2324 to move left and right. Inside the second housing 2321, after the first motor 2322 is started, it drives the lead screw 2323 to rotate. This rotation causes the lead screw nut 2324 to move left and right in the horizontal direction. As the lead screw nut 2324 moves, it pulls the rotating component 233 to slide left and right along the preset moving groove 2325.

[0029] The rotating assembly 233 includes a second housing 2331. A second motor 2332 is fixedly connected to the base plate of the second housing 2331. The output end of the second motor 2332 is fixedly connected to the rotating shaft 2333. A turntable 2334 is fixedly connected to the other end of the rotating shaft 2333. A connecting rod 2335 is fixedly connected to the bottom of the turntable 2334. A laser head 2336 is fixedly installed on the side of the connecting rod 2335 near the bottom mold 22. An infrared spotlight 2337 is fixedly connected to the second housing 2331, and the infrared spotlight 2337 is located directly above the rotating shaft 2333. After the second motor 2332 is started, it drives the rotating shaft 2333 to rotate. This rotation then drives the turntable 2334 to rotate as well. As the turntable 2334 rotates, the connecting rod 2335 is driven to move in a circular motion around the bottom mold 22. During this process, the laser beam emitted by the laser head 2336 can accurately cut off the excess material of the trash can after hydroforming.

[0030] It should be noted that a clear center mark is provided at the bottom of the pressure head 21. When the infrared light emitted by the infrared spotlight 2337 is precisely pointed to this center mark, it indicates that the rotating shaft 2333 has been precisely positioned directly above the center of the bottom mold 22. At this time, the rotating column 2333 is driven to start rotating, and the laser head 2336 will move along a circular path, which exactly circles the bottom mold 22.

[0031] The raw material for the garbage bin to be processed is placed above the bottom mold 22. The operation of the four-column hydraulic press can be fully controlled through the control panel 161. The hydraulic motor 163 draws hydraulic oil from the hydraulic oil tank 162 through the hydraulic oil pipe 17 and injects this hydraulic oil into the hydraulic cylinder 11. As the oil in the hydraulic cylinder 11 increases, the hydraulic shaft 15 is pressured and descends, thereby driving the lifting plate 14 to descend smoothly along the sliding column 13. When the lifting plate 14 moves down, it drives the pressure head 21 to descend synchronously. When the pressure head 21 contacts the raw material of the garbage bin, it continues to press down until the groove 211 on it is tightly combined with the bottom mold 22 below, forming the garbage bin.

[0032] Inside the second housing 2321, the first motor 2322 starts and drives the lead screw 2323 to rotate. This rotation causes the lead screw nut 2324 to move left and right in the horizontal direction. As the lead screw nut 2324 moves, it pulls the rotating assembly 233 to slide left and right along the preset moving groove 2325. At the bottom of the pressure head 21, there is a clear center mark. When the infrared light emitted by the infrared spotlight 2337 accurately points to this center mark, it means that the rotating shaft 2333 has been precisely positioned directly above the center of the bottom mold 22. At this time, the first motor 2322 stops, and the second motor 2322 starts, driving the rotating shaft 2333 to rotate. This rotation causes the turntable 2334 to rotate as well. As the turntable 2334 rotates, the connecting rod 2335 is driven to move in a circle around the bottom mold 22, and the laser head 2336 moves along a circular path that exactly circles the bottom mold 22. During this process, the laser beam emitted by the laser head 2336 can precisely cut off the excess material in the trash can after it has been hydroformed.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
