Description

Technical Field

[0001] The utility model relates to the technical field of powder forming hydraulic presses, and more specifically, to a clamping device of a powder forming hydraulic press. Background Art

[0002] A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the machine (host), the power system, and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses.

[0003] At present, the clamping devices on the market usually clamp the workpiece to move it during production and processing. However, when the clamping force of the clamping device is too large, the clamped workpiece may be damaged; when the clamping force of the clamping device is too small, the workpiece is prone to detachment.

[0004] In addition, manual clamps often cannot achieve a large clamping force, and a large clamping force often causes the clamp block to move due to force and vibration, resulting in unstable material clamping. In addition, components molded by powder forming hydraulic presses require special clamping mechanisms. Utility Model Content

[0030] See also Figure 1 , Figure 2 and Figure 3A clamping device for a powder forming hydraulic press includes a base structure 1, the base structure 1 is used for supporting and fixing, a transmission mechanism 2 installed at the front end of the base structure 1, and a clamping mechanism 3 installed at the front end of the transmission mechanism 2, and the transmission mechanism 2 drives the clamping mechanism 3 to move.

[0031] The base structure 1 includes a mounting plate 11 and two mounting side panels 17. The two mounting side panels 17 are symmetrically arranged on one side of the mounting plate 11. A connecting bottom plate 18 is arranged in the middle of the mounting side panels 17. The connecting bottom plate 18 is symmetrically installed and used to fix the symmetrically arranged mounting side panels 17. A hinge groove 110 is arranged on the mounting side panels 17.

[0032] The transmission mechanism 2 includes an axisymmetrically arranged gear articulated support rod 25 and a transmission articulated support rod 26. The gear articulated support rod 25 and the transmission articulated support rod 26 are articulated on the mounting side plate 17 through bolts and articulated grooves 110. One side of the gear articulated support rod 25 is in a semi-gear shape for meshing transmission. The transmission articulated support rod 26 is used to extend forward so that the clamping mechanism 3 can be clamped in the middle. The clamping mechanism 3 is articulated with the gear articulated support rod 25 and the transmission articulated support rod 26.

[0033] The clamping mechanism 3 includes a bracket 34 installed between two mounting side plates 17, a clamping column 35 is installed on one side of the bracket 34, and clamping grooves 36 are symmetrically arranged on the clamping column 35. The clamping grooves 36 have a buffering effect when the material is clamped, and can prevent the material from being squeezed and deformed.

[0034] See also Figure 1 The base structure 1 also includes a mounting plate 11, which is used to be installed on other machines. A connecting slot 12 is arranged through the mounting plate 11. Such a structure is more stable to install. The mounting plate 11 is provided with a connecting slot 12, which is rectangular and equidistantly arranged along the axis. The mounting plate 11 is also provided with a mounting groove 13, which is circular and equidistantly arranged along the axis.

[0035] See also Figure 1 A mounting column 14 is installed on one side of the mounting plate 11, and connecting blocks 15 are equidistantly arranged along the periphery of the mounting column 14. One end of the connecting block 15 fits with the connecting slot 12. A mounting chassis 112 is installed on the other side of the mounting column 14. The mounting chassis 112 is rectangular and has four chamfered corners. The mounting chassis 112 is connected to two mounting side panels 17.

[0036] See also Figure 1 A fixing groove 16 is provided on the mounting chassis 112 , a support block 111 is installed on one side of the mounting chassis 112 at a position matching with the fixing groove 16 , a mounting side plate 17 is installed on one side of the mounting chassis 112 , and a bottom plate mounting groove 19 is provided on the mounting side plate 17 .

[0037] See also Figure 2The transmission mechanism 2 also includes a cylinder 22, which is installed in the middle of the mounting side plate 17. The mounting side plate 17 and the connecting bottom plate 18 form a rectangular structure to stably support the cylinder 22. A No. 1 transmission air pump 21 and a No. 2 transmission air pump 23 are installed on one side of the cylinder 22. A transmission shaft 24 is connected to one side of the cylinder 22. The cooperation principle of the cylinder 22, the No. 1 transmission air pump 21 and the No. 2 transmission air pump 23 is that when the No. 1 transmission air pump 21 is inhaled, the No. 2 transmission air pump 23 is discharged, so that The transmission shaft 24 extends out from the cylinder body of the cylinder 22. Conversely, when the No. 2 transmission air pump 23 takes in air, the No. 1 transmission air pump 21 discharges air, causing the transmission shaft 24 to shrink into the cylinder body of the cylinder 22. The cylinder 22 pushes the transmission shaft 24. A gear transmission support 27 is installed on one side of the transmission shaft 24. The gears on both sides of the gear transmission support 27 are meshed with two gear articulated support rods 25. When the transmission shaft 24 is pushed forward, the gear articulated support rod 25 opens, and when the transmission shaft 24 is pushed backward, the gear articulated support rod 25 tightens.

[0038] See also Figure 3 The clamping mechanism 3 includes two connecting arms 31 symmetrically arranged in an upper and lower manner. One side of the two connecting arms 31 is hinged to the gear hinge support rod 25 and the transmission hinge support rod 26. A support rod 32 is installed on the other side of the connecting arm 31. A clamping support block 33 is installed on one side of the support rod 32. A support groove 37 is arranged on the clamping support block 33. The support groove 37 is arc-shaped. The support groove 37 has a buffering effect when clamping the material, which can prevent the material from being squeezed and deformed.

[0039] Specifically, the clamping device is connected to the external manipulator. After the powder molding hydraulic press processes the workpiece, the cylinder 22 drives the transmission shaft 24 and the gear transmission support 27 forward. Since the gears on both sides of the gear transmission support 27 are meshed with the two gear hinged support rods 25, the meshing teeth on the gear transmission support 27 change position. Therefore, when the gear transmission support 27 is displaced, the two gear hinged support rods 25 swing under the influence of the meshing force, causing the clamping mechanism 3 to open. When the clamping device is aligned with the material, the cylinder 22 drives the transmission shaft 24 backward, driving the gear transmission support 27, and the clamping mechanism 3 is tightened. The two materials are clamped in the middle position of the clamping groove 36 and the support groove 37. After the material is clamped, the external manipulator drives the clamping device to move to the unloading position, and then the clamping mechanism 3 opens again, and the material is placed in the unloading position. After that, the external manipulator drives the clamping device again to perform the clamping operation.

[0040] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
