Embodiment Construction

[0017] Embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0018] After starting the equipment; firstly, the metal powder is loaded on the feeding manipulator; the upper pallet 12 drives the punch 10 to move downward at a speed of 30-60mm / min; when the guide sleeve 13 of the punch part contacts the die 14; the hydraulic motor 3 Start to work; through the transmission of the pinion 4 and the bull gear 22; the torque is transmitted to the rotating main shaft 15; the main shaft 15 drives the die 14 to rotate at a speed of 500-600rpm; the guide sleeve 13 contacts the outer wall of the die 14; at the same time, the deep groove ball The bearing 8 starts to rotate; at this moment, the upper supporting plate 12 drives the punch 10 to advance at a speed of 10-30mm / min. The die 14 at a rotational speed of 500-600rpm causes the metal powder to generate centrifugal force; as the punch 10 advances downw...

Abstract

The invention relates to an automatic spinning device of a perforating bullet cumulative cover and a forming method, belonging to the production field of exploiting perforating bullets in an oil-gas field. The automatic spinning device comprises an upper die and a lower die which are mounted on a hydrostatic press, wherein the upper die comprises a punch bearing seat, a punch bearing end cover, afirst deep groove ball bearing, a punch, a punch-connecting plate, an upper splint, a guide sleeve and screws; and the lower die comprises a die-opening air cylinder, a die-opening air cylinder seat,a hydraulic motor, a pinion, a lower splint, a main shaft bearing seat, a guide sleeve, a concave die, a main shaft, a main shaft bearing end cover, a die-opening spring, a die-opening rod, a second deep groove ball bearing, a sleeve, an angular contact bearing, a rack wheel, round nuts, a jacking long rod, a rotary joint, threads and screws. The cumulative cover is formed by rotatably pressing, keeping pressure and returning to restore so as to finish the rotatable pressing of the next cumulative cover. The invention improves a two-step pressing technology of the cumulative cover and has theadvantages of high quality, simplified technology, high efficiency, high reliability, greatly improved automated safe production, and the like.

Description

technical field [0001] The invention relates to an automatic spinning device and molding method for a perforating bullet energy-collecting cover, which belongs to the field of production of perforating bullets used in oil and gas fields, and in particular to automatic weighing of perforating bullet energy-collecting cover metal powder, automatic spinning equipment and wall thickness Automatic measurement technology. Background technique [0002] The known pressing process of the energy-gathering cover is divided into two types. The early energy-gathering cover was punched or rolled from a plate. Because the quality could not meet the requirements of oil and gas field production, it was gradually replaced by a new process. After the appearance of the metal powder shaped cover recently, the perforation performance of the shaped charge has been greatly improved. At present, advanced countries and my country have adopted this kind of shaped cover. The production mainly adopts th...
