Petroleum perforating bullet four-station forming device

Abstract

The invention belongs to the field of pressing and forming tools for petroleum perforating bullets and discloses a petroleum perforating bullet four-station forming device which comprises a device base and a stand column. The stand column is provided with a first fixing disc, a second fixing disc, a first forming disc and a second forming disc in a sleeved manner. The lower end of the first fixingdisc is connected with a first hydraulic oil cylinder. The upper end of the second fixing disc is connected with a second hydraulic oil cylinder. Four first forming grooves are uniformly formed in the lower end of the first forming disc. Four second forming grooves are uniformly formed in the upper end of the second forming disc. The cross section of the stand column is in a round structure, anda fool-proofing block is arranged at one end of the stand column. Fool-proofing holes are formed in the portions, sleeving the stand column, of the first fixing disc, the second fixing disc, the firstforming disc and the second forming disc. According to the device, pressure is applied to the two sides of the first forming grooves and the two sides of the second forming grooves at the same time,the density of obtained petroleum perforating bullets is more compact, internal cartridge bags are distributed more uniformly, and the effect of the obtained petroleum perforating bullets is better.

Description

technical field [0001] The invention relates to the technical field of press molding tooling for petroleum perforating bullets, in particular to a four-station forming device for petroleum perforating bullets. Background technique [0002] Petroleum perforating charge is an explosive device used in the development of oil and gas fields to communicate with oil well casing and oil and gas layers. The main structure of petroleum perforating bullets includes powder powder cover, casing and explosives. At present, in actual production, the one-time molding press-fitting method is mainly used to press these three parts into petroleum perforating bullets. However, the one-time molding in the prior art The press-packing method adopts one-sided pressure for pressing. This kind of pressing has the disadvantages of relatively large one-sided pressure, insufficient density, and uneven pressing, which is not conducive to improving product quality. In view of this, how to provide a four-...

Problems solved by technology

The main structure of petroleum perforating bullets includes powder powder cover, casing and explosives. At present, in actual production, the one-time molding press-fitting method is mainly used to press these three parts into petroleum perforating bullets. However, the one-time molding in the prior art The press-fitting method adopts unilateral pressure for pressing. This kind of pressing has the disadvantages of high unilateral pressure, insufficient density, and uneven pressing, which is not conducive to improving product quality.
