Description

Technical Field

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

[0002] The hinged six-sided top press is the most widely used large-cavity press in China. This type of press has the advantages of simple ultra-high pressure mold structure, low cost, and easy operation. It is a commonly used equipment for synthesizing superhard materials such as diamond and cubic boron nitride in China. This type of press consists of six independent hinged beams, which are connected by inserting "ears" into each other and fixing the "ears" with pins.

[0003] When the six-sided top press is working, the six large pistons simultaneously generate a huge thrust toward the middle, causing the six large oil cylinders to be subjected to a reverse force. After a traditional hinged press is used for a long time, the "ears" are prone to tearing, causing the oil cylinders to be scrapped. Since the pin is located at the front end of the "ears", simply increasing the thickness of the "ears" will reduce the working area of ​​the press, affecting the smooth progress of production. Therefore, in order to increase production, the concept of "big horse pulling a small cart" is adopted to use large presses, that is, using a large oil cylinder diameter with a small oil pressure to achieve the required thrust. Although this plays a certain role in protecting the hinge beam, it greatly increases the cost of the press due to the enlargement of the volume of the press. Utility Model Content

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

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

[0006] A durable six-sided top press comprises a pressure beam, a connecting block connected to the pressure beam through a pin shaft, pressure beams located on six faces, adjacent sides of two adjacent pressure beams are hinged together, four connecting ears are circumferentially distributed on the outer wall of the pressure beam, at least two connecting ear pin shaft holes are opened on the connecting ears, wherein the minimum straight-line distance from at least two connecting ear pin shaft holes to the center of the hexahedral structure is 0.7 times to 2 times the minimum vertical distance from the center of the hexahedral structure to the bottom surface of the piston cavity.

[0007] Preferably, the number of connection blocks connected to a single connection ear is two, and the connection blocks are clamped on both sides of the connection ear.

[0008] Preferably, the number of the connecting block connected to the single connecting ear is one, a slot adapted to the connecting ear is provided in the middle of the connecting block, and the connecting block is sleeved on the outer side of the connecting ear.

[0009] Preferably, the diameter of the pin shaft hole of the connecting ear located at the rear end of the pressure-bearing beam is larger than the diameter of the pin shaft hole of the connecting ear located at the front end of the pressure-bearing beam.

[0010] The beneficial effects of the utility model are:

[0011] 1. Compared with the traditional hinged six-sided press, the durable six-sided press proposed by the utility model has at least one connecting ear pin shaft hole at the rear end of the connecting ear, so that the length of the area on the connecting ear subjected to the pin shaft tension is significantly increased. Under the condition that the thickness of the connecting ear remains unchanged, the tensile performance of the connecting ear can be greatly improved. The press structure can withstand higher working pressure, and the six-sided press is stable and durable. On the other hand, after the connecting ear pin shaft hole on the connecting ear is moved backward, the connecting ear can form a whole with the area on the pressure beam located at the rear of the piston cavity, further improving the tensile performance of the connecting ear.

[0012] 2. The large-cavity six-sided top press structure proposed by the utility model has at least two connecting ear pin shaft holes on the connecting ear. When one end of the connecting block is connected to the connecting ear, the connecting block cannot rotate freely around the pin shaft. When the six-sided top press is assembled, the connecting block cannot rotate, and there is no need to limit the connecting block, thereby improving the installation efficiency. When the six-sided top press is disassembled, the connecting block cannot rotate, thereby preventing the connecting block from suddenly rotating and hitting the operator or other objects, thereby improving the safety of the device.
