Description

Technical Field

[0001] The utility model relates to the technical field of six-sided top press machines, in particular to a combined limiting mechanism for a six-sided top press machine. Background Art

[0002] In recent years, as the price of artificial diamonds has been falling, the diamond industry has become more and more demanding on cost control. In order to reduce the cost per carat, in addition to conventional management methods, developing a six-sided top press with a larger cylinder diameter is one of the most effective methods.

[0003] The six-sided top press is the most widely used large-cavity press in China. This type of press has the advantages of strong self-centering, low cost, and easy operation. It is the main equipment for synthesizing superhard materials such as diamond and cubic boron nitride (CBN) in China. The existing six-sided top press is composed of six hinged beams that are hinged to each other through beam ear holes and pin shafts. During the use of the six-sided top press, the hinged beam ears are prone to tearing. In order to improve the tensile properties of the hinged beam ears and further improve the pressure resistance of the six-sided top press, one of the existing feasible operating methods is to set a frame outside the six-sided top press, and limit the six-sided top press through the frame to improve the pressure resistance of the six-sided top press. However, the six-sided top press itself is already very large, and setting up the frame requires a large amount of steel, as well as increasing the floor space of the equipment and increasing production costs. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a six-sided top press combined limiting mechanism.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A combined limiting mechanism of a six-sided top press comprises a limiting block body and a connecting plate. Limiting parts adapted to the rear end surface of a hinge beam are arranged at both ends of the limiting block body. The corresponding hinge beam is limited to move in the axial direction by the limiting parts. The limiting parts are perpendicular to each other. Connecting parts are arranged between the limiting parts. Connecting ears are arranged around the hinge beam. The connecting ears are connected to the connecting plate by a first pin. The limiting block body and the connecting plate are detachably connected.

[0007] Preferably, a first latch hole is formed on the connecting ear, and the first latch passes through the first latch hole to be connected to the connecting plate.

[0008] Preferably, the connecting portion and the connecting plate are connected via a second latch.

[0009] Preferably, a second latch hole is formed on the connecting portion, and the second latch is matched with the second latch hole.

[0010] Preferably, the end surface of the connecting portion fits with the end surface of the connecting ear.

[0011] The beneficial effects of the utility model are as follows: the limit block body is matched with the connecting plate to fix the limit block body around the hinge beam, and the limit part in the limit block body limits the hinge beam, which can effectively improve the pressure resistance of the equipment, that is, improve the service life of the connecting ear in the hinge beam, and compared with the traditional frame structure, the limit block body is smaller in size and lighter in weight, and is suitable for popularization and use.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-6A combined limiting mechanism of a six-sided top press includes a limiting block body 2 and a connecting plate 3. Limiting parts 21 adapted to the rear end surface of the hinge beam 1 are arranged at both ends of the limiting block body 2. The corresponding hinge beam 1 is limited to move in the axial direction by the limiting parts 21. The limiting parts 21 are perpendicular to each other. Connecting parts 22 are arranged between the limiting parts 21. Connecting ears 11 are arranged around the hinge beam 1. The connecting ears 11 are connected to the connecting plate 3 through a first pin 4. The limiting block body 2 and the connecting plate 3 are detachably connected.

[0021] A first latch hole 12 is formed on the connecting ear 11 , and the first latch 4 passes through the first latch hole 12 to be connected to the connecting plate 3 .

[0022] The connecting portion 22 is connected to the connecting plate 3 via a second latch pin 5 . A second latch pin hole 23 is formed on the connecting portion 22 . The second latch pin 5 is matched with the second latch pin hole 23 .

[0023] The end surface of the connecting portion 22 is in contact with the end surface of the connecting ear 11. According to actual needs, the shape of the connecting portion 22 that meets the requirements can be set, such as Figure 5 As shown, the connecting portion 22 is triangular in shape as a whole, and the mass of the connecting portion 22 is relatively low. Figure 6 As shown, the connecting portion 22 is fan-shaped as a whole, and the strength of the connecting portion 22 is higher.

[0024] In this embodiment, the limit block body 2 is fixed around the hinge beam 1 by cooperating with the connection plate 3. The limit portion 21 in the limit block body 2 limits the hinge beam 1, which can effectively improve the pressure resistance of the equipment, that is, improve the service life of the connecting ear 11 in the hinge beam 1. Compared with the traditional frame structure, the limit block body 21 is smaller in size and lighter in weight, and is suitable for popularization and use.
