Description

A low-energy consumption hydraulic press for graphite column production

Technical Field

The utility model relates to the technical field of oil presses, in particular to a low-energy consumption oil press for producing graphite columns.

Background Art

A hydraulic press is a machine that uses special hydraulic oil as the working medium and a hydraulic pump as the power source. The hydraulic oil enters the cylinder/piston through the hydraulic pipeline by the force of the pump. Then there are several sets of seals that cooperate with each other in the cylinder/piston. The seals in different positions are different, but they all play a sealing role to prevent the hydraulic oil from leaking. Finally, the hydraulic oil circulates in the oil tank through a one-way valve to make the cylinder/piston circulate and do work, thereby completing a certain mechanical action as a kind of productivity. When producing graphite columns, a hydraulic press is needed to press graphite powder into graphite columns.

A new type of low-energy hydraulic press is disclosed in the Chinese utility model with publication number CN213972703U. It has an inner die seat installed inside the upper die seat, which can extrude small workpieces without activating the entire upper die seat, thus facilitating energy saving and improving the flexibility and efficiency of processing.

When the device unloads the pressed part in the lower mold cavity, it still uses the method of adding a hydraulic cylinder to complete the ejection of the pressed part. It needs to use multiple power sources to complete the overall production of the pressed part, which consumes a lot of energy. To this end, we provide a low-energy hydraulic press for graphite column production to solve the above problems.

As shown in Figures 1-3, the utility model provides a technical solution: a low-energy hydraulic press for producing graphite columns, including a main frame, an upper mold assembly, a lower mold assembly, a blanking assembly and a linkage assembly.

The main frame includes a mounting seat 1, a base 3 and two groups of columns 2. The two ends of the two groups of columns 2 are respectively fixedly connected to the mounting seat 1 and the base 3. The columns 2 are used to form a space between the mounting seat 1 and the base 3.

The upper mold assembly includes a hydraulic cylinder 5 installed on a mounting base 1, a lifting platform 6 is installed on the telescopic end of the hydraulic cylinder 5, and an upper mold 7 is installed on the lifting platform 6. The hydraulic cylinder 5 is an existing structure, and the lifting platform 6 is lifted and moved by using oil as a power source, and the lifting platform 6 can slide on the column 2. The upper mold 7 is installed on the lifting platform 6 by bolts, and the upper mold 7 can be disassembled and replaced.

The lower mold assembly includes a lower mold 4 installed on the base 3 and a molding cavity 8 opened on the lower mold 4. The lower mold 4 can be installed on the base 3 by bolts so as to replace the lower mold 4, and the molding cavity 8 is cylindrical.

The blanking assembly includes a movable groove 9 opened on the lower mold 4, a movable plate 10 slidably connected to the movable groove 9, and a push rod 16 installed on the movable plate 10. The top end of the push rod 16 passes through the molding cavity 8 and extends to the interior of the molding cavity 8. The blanking assembly also includes a storage groove 15 opened on the top wall of the molding cavity 8, and a blanking plate 17 installed on the push rod 16. The blanking plate 17 matches the storage groove 15.

When the movable plate 10 moves upward in the movable groove 9, the upper push rod 16 of the movable plate 10 can be inserted into the interior of the molding cavity 8, and the unloading plate 17 can be detached from the receiving groove 15 into the molding cavity 8, thereby completing the unloading of the molded graphite column in the molding cavity 8.

The linkage component is detachably mounted on the movable plate 10, and is used to enable the lifting platform 6 to drive the movable plate 10 to perform synchronous lifting and lowering. The linkage component includes a threaded sleeve 11 installed on the movable plate 10, and a screw rod 12 threadedly connected to the threaded sleeve 11. The top of the screw rod 12 passes through the lifting platform 6 and is threadedly connected to a fixing nut 14. When the lifting platform 6 moves downward, since there is no structure to limit the screw rod 12 below the lifting platform 6, the lifting platform 6 will drive the movable plate 10 to move downward through the screw rod 12, and the screw rod 12 is connected to the movable plate 10 through the threaded sleeve 11, which can facilitate the replacement of the screw rod 12. When the lifting platform 6 moves upward, the lifting platform 6 can drive the screw rod 12 to move upward through the fixing nut 14, and the movable plate 10 can drive the top rod 16 to move.

Working principle: First, pour the graphite powder into the molding cavity 8. At this time, the blanking plate 17 is located inside the receiving groove 15. Then, start the hydraulic cylinder 5, so that the telescopic end of the hydraulic cylinder 5 drives the lifting platform 6 to move downward, and insert the upper mold 7 into the molding cavity 8 to complete the mold closing movement, so that a graphite column is formed in the molding cavity 8. At this time, since there is no structure to limit the screw rod 12 under the lifting platform 6, the lifting platform 6 slides on the screw rod 12. Finally, start the hydraulic cylinder 5, so that the telescopic end of the hydraulic cylinder 5 drives the lifting platform 6 to move upward, and pulls the upper mold 7 out of the molding cavity 8. At this time, when the lifting platform 6 moves upward, the lifting platform 6 can drive the screw rod 12 to move upward through the fixing nut 14, and the movable plate 10 drives the push rod 16 to move, and the blanking plate 17 is separated from the receiving groove 15 into the molding cavity 8, completing the unloading of the graphite column formed in the molding cavity 8.
