Problems solved by technology

[0003] At present, domestic perforating bullet manufacturers all use manual glue coating on the outside of the liner to produce perforating bullets. Due to uneven manual glue coating, sometimes a lot of glue is applied on the outside of the liner, and the perforating bullets are easy to press during the pressing process. As a result, the symmetric axis of the liner and the liner of the perforating charge do not coincide, which affects the penetration performance of the perforating charge, and some even cause cracking of the charge, resulting in the scrapping of the entire perforating charge, thereby increasing production costs

Abstract

The invention discloses an automatic glue spraying device for a shaped charge liner of a perforating charge in embodiments. The automatic glue spraying device comprises a shell, a covering plate disposed at the opening of the shell, and a bearing tray propped at the lower end of the cover plate and used for bearing the shaped charge liner of the perforating charge, wherein a support is disposed in the shell, a rotation platform is disposed on the support, the rotation platform is driven to rotate by a motor which is fixed to the support by the fixed end of the rotation platform, the cover plate is provided with an anaerobic adhesive spraying gun, and when the covering plate lowers to a preset distance, the rotation platform holds up the bearing tray. The automatic glue spraying device guarantees consistency of the glue thickness outside the shaped charge liner and largely reduces the rejection rate of the perforating charge.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to an automatic glue spraying device for perforating ammunition cover. Background technique [0002] The perforator is a combination of equipment (or device) and its accessories used for perforating oil and gas wells. Its function is to open the casing and cement sheath of the downhole closed oil and gas layer and penetrate into the oil and gas layer to establish communication between the wellbore and the oil and gas layer. The performance of the channel directly affects the effect of perforation completion. [0003] At present, domestic perforating bullet manufacturers all use manual glue coating on the outside of the liner to produce perforating bullets. Due to uneven manual glue coating, sometimes a lot of glue is applied on the outside of the liner, and the perforating bullets are easy to press during the pressing process. As a result, the symmetry axis of the ...
