Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for superhard material synthesis, and particularly relates to an anti-loosening and anti-detaching device for the upper anvil of a six-sided press. Background Technique

[0002] A six-sided diamond synthesis press uses six cemented carbide anvils, which are opposite to each other in pairs and apply force to the center simultaneously from the up, down, front, back, left and right directions to form a super-high pressure environment for the growth of superhard materials. The relative positions of the six cemented carbide anvils determine the centering of the synthesis press. The cemented carbide anvils are fixed on the large cushion block of the press through four positioning bolts to ensure the centering level of the anvils. Repeated overpressure and pressure relief during the operation of the six-sided press will cause the positioning bolts to loosen. If not tightened in time, it will cause the separation of the cemented carbide anvil from the large cushion block or the position deviation of the cemented carbide anvil, which may lead to equipment accidents. Due to the special position of the upper anvil, if the positioning bolts loosen, it will cause the separation of the upper anvil from the large cushion block or the deviation of the force direction of the anvil, resulting in the deformation of the synthesis block, and it is extremely easy to occur accidents such as cracked anvil blasting or the falling of the upper anvil and injuring people. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti-loosening and anti-detaching device for the upper anvil of a six-sided press, which solves the problem of the loosening of the positioning bolts in the prior art, resulting in the falling of the anvil.

[0004] The technical solution adopted by the utility model is that the anti-loosening and anti-detaching device for the upper anvil of a six-sided press includes a support ring, and a pull plate module is connected to the support ring.

[0005] The characteristics of the utility model also lie in:

[0006] The pull plate module includes four upper pull plates and four lower pull plates. Four upper pull plates are coaxially connected to the upper end of the support ring, and four lower pull plates are coaxially connected to the lower end of the support ring.

[0007] The support ring is connected to the four upper pull plates through snap rings, and the support ring is connected to the four lower pull plates through snap rings.

[0008] The longitudinal section of the upper pull plate is L-shaped, and a circular through hole is provided on the end face of the upper pull plate.

[0009] A circular through hole is provided on the end face of the lower pull plate.

[0010] The beneficial effect of the utility model is:

[0011] The anti-loosening and anti-detaching device for the upper anvil of a six-sided top press provided by the present utility model uses the method of anti-loosening by friction to integrally upwardly tension the four positioning and fastening bolts of the upper anvil with an upper pulling plate and a lower pulling plate, generating a radial positive tension that does not change with external forces between the thread pairs, so as to generate a frictional force that prevents the relative rotation of the thread pairs of the anvil fixing bolts, solve the problem of loosening of the anvil fixing bolts, reduce the abnormal anvil consumption and the loss rates of the large and small pads, and save costs.
