A kind of perforating ammunition type cover multi-station composite pressing equipment

Abstract

The invention discloses a multi-station composite pressing equipment for a perforating ammunition type cover, comprising a hydraulic press unit, wherein the hydraulic press unit is a three-station eight-column hydraulic press unit, and the hydraulic press unit of each station includes an upper beam, a lower beam, a Slide block, worktable, column, nut, master cylinder, anti-rotation guide devices are provided between the top of the slide block and the upper beam, and rotating mechanism devices are provided between the bottom of the worktable and the lower beam. The anti-rotation guide device includes a guide rod and a guide cylinder. The guide rod and the guide cylinder are provided with precision couplers and are movably plugged in. There are four guide rods and guide cylinders in each station, and The guide rods are evenly arranged on the top of the slider, and the guide cylinders are arranged inside the upper beam. In the present invention, by setting the device to three stations, it is beneficial to firstly use a station with lower pressure for pre-pressing and pressing, and then change it to a station with higher pressure for shaping and pressing, thereby improving the molding efficiency of the medicine type cover .

Description

technical field [0001] The invention relates to the technical field of pressing and forming of perforating ammunition powder hoods, in particular to a multi-position composite pressing equipment for perforating ammunition hoods. Background technique [0002] As a kind of completion equipment for establishing effective channels in wellbore and oil layer, the quality of perforating charges will greatly affect the oil and gas production of production wells. The charge cover is the key component of the perforating charge. The uniformity of the structure size and quality of the charge cover is very critical to the performance of the perforating charge. Therefore, the suppression of the perforating ammunition shroud is a crucial link. [0003] In the past, the perforating ammunition cover was made of copper rod material; currently, some people have developed powder formulations that are pressed and formed by hydraulic press single-machine single-mode vibration and single-machine ...

AI Technical Summary

Problems solved by technology

[0003] In the past, the perforating ammunition cover was made of copper rod material; at present, someone has developed a powder formula that is pressed and formed by hydraulic machine single-machine single-mode vibration and single-machine single-mode spinning; these two pressing methods are independent. The hydraulic press directly applies high pressure to the metal powder to form it (generally, the forming pressure of the formula drug cover is 110T-120T); the disadvantage is that the high pressure will cause great damage to the mold, making it easy to deform the mold and the probability of unqualified products. Greatly improved, especially in the single-machine spinning method, when the high pressure is applied to the inner spinning core of the mold, the high pressure will cause greater damage to the core
