Mechanical-hydraulic hybrid loading and automatic compensation type belt-type press and method

Abstract

The invention discloses a mechanical-hydraulic hybrid loading and automatic compensation type belt-type press and method. According to the press, an upper cross beam is arranged above a frame and is fixedly connected with the frame; a main screw is arranged in a hole in the upper cross beam; the upper end of the main screw penetrates out of the upper cross beam and then is coaxially connected witha driven gear; a positive and negative rotation motor is arranged in the upper cross beam; an output shaft of the positive and negative rotation motor is coaxially connected with a transmission gear,and the transmission gear is meshed with the driven gear to form a gear pair; the lower end of the main screw is in threaded connection with the upper end of a main nut; the lower end of the main nutis fixedly connected with an upper pressing block through a bolt; the upper pressing block is sleeved with a stand column; the main screw, the main nut and the stand column form a lead screw slidingpair; a hydraulic cylinder is fixedly installed on the bottom end face of the upper pressing block; and an output piston rod is axially and fixedly connected with a threaded flange. A mechanical transmission and hydraulic transmission hybrid loading structure is adopted in the invention, so the power transmission performance of the press is greatly improved; and the pressure value of a hydraulic cylinder is dynamically adjusted and automatically compensated through a pressure sensor, so the requirement for high accuracy can be met, and reliability and stability are improved.

Description

technical field [0001] The invention relates to a diamond press, more specifically, to a machine-liquid mixed loading and automatic compensation type double-sided top press and method. Background technique [0002] Diamond is currently the hardest substance known to man in nature. Because of its excellent mechanical, electrical, optical and thermal properties, it has been widely used in petroleum, coal, metallurgy, instrumentation, national defense and other sectors. of superhard materials. [0003] So far, there are many ways to synthesize diamond. However, the static high temperature and high pressure method in the high pressure method is generally used. The widely used structural forms of presses mainly include two-sided tops and six-sided tops. The double-sided top pressing machine forms a completely closed space when pressed by the upper and lower hammers and the double-sided top mold, which can be continuously pressurized and has a long synthesis time. Therefore, t...
