Description

Technical Field

[0001] The utility model relates to the technical field of artificial diamond production equipment, in particular to a pre-pressing device of an anvil for artificial diamond production. Background Art

[0002] In the superhard materials industry, diamond has long been the preferred choice for various tool accessories due to its exceptional hardness. As early as the last century, my country developed a polyhedron top press for producing synthetic diamonds. The principle is to add additives to the raw material. The polyhedron top press drives the top hammer to pressurize the raw material at high temperature and pressure, causing the raw material to form diamonds under high temperature and pressure.

[0003] At present, in the production process of artificial diamonds, it is difficult to ensure the sealing of the newly installed top hammer or the top hammer replaced after maintenance because it is not evenly covered with pyrophyllite powder. Therefore, after the top hammer is newly installed or replaced after maintenance, there will be a process of pre-pressing the pyrophyllite block to ensure that the surface of the top hammer is evenly covered with pyrophyllite powder.

[0004] The existing application publication number CN115414866A discloses a pre-pressing device and method for a top hammer for artificial diamond production. The device comprises a press, a top hammer fixture and a metal kettle for placing prefabricated blocks. The metal kettle is arranged in the lower groove of the press and has a square bucket-shaped structure. The square bucket-shaped structure includes a first extension portion, a second extension portion and a rectangular groove at the bottom extending inward from the four corner edges in sequence. The angle between the first extension portion and the vertical direction is greater than the angle between the second extension portion and the vertical direction, and the inclination angle of the second extension portion is the same as the surface inclination angle of the top hammer. The device simulates the process of pre-pressing solid pyrophyllite blocks. After repeated pre-pressing processes, the surface of the top hammer is evenly covered with pyrophyllite powder, so that the newly replaced or newly repaired top hammer can be directly put into production after replacement, saving the process waste, material waste and time waste of repeatedly pre-pressing solid pyrophyllite blocks, and can be directly put into production.

[0005] However, this solution still has some shortcomings. In actual use, the lower inner expansion ring of the outer cylinder is fastened to the preload hammer by fastening bolts, which is inconvenient to install and disassemble; and the inner ring size of the inner expansion ring cannot be adjusted, which cannot meet the equipment requirements of preload hammers of different sizes.

[0006] Therefore, it is necessary to provide a pre-pressing device for an anvil for producing artificial diamonds to solve the above technical problems. Utility Model Content

A slide groove 16 is provided at the bottom of the partition 6. The top of the locking plate 8 is slidably connected to the slide groove 16.

[0025] The screw rod 13 is driven to rotate by the forward and reverse rotation of the motor 14, thereby controlling the up and down movement of the rod sleeve 12 and driving the connecting rod 11 to flip up and down. The locking plate 8 slides in the slide groove 16 and drives the bottom support plate 9 to move. The pre-stressing top hammer 5 is grabbed by the support plate 9, and the top hammer fixture 1 and the pre-stressing top hammer 5 are controlled by the press 3 to rise and fall for pre-stressing treatment.

[0026] Furthermore, there are four slides 7, and the slides 7 are arranged in a ring shape and evenly distributed on the bottom plate 15. The number of locking plates 8 and slide grooves 16 corresponds one-to-one to the slides 7. The inner side of the locking plate 8 is connected to the fixed plate 10, and the connecting rod 11 is rotatably connected to the locking plate 8 through the fixed plate 10. There are multiple connecting rods 11, and each locking plate 8 is connected to two connecting rods 11, and the two connecting rods 11 on each locking plate 8 are arranged up and down.

[0027] There are four locking plates 8 and four supporting plates 9, so that during the grabbing process, the force applied to the pre-stressing hammer 5 is more uniform, thus avoiding tilting and uneven coating of the pre-stressing material on the surface of the pre-stressing hammer 5.
