An automatic loading and unloading device for perforating charge assembly and its assembly process

Abstract

The invention discloses an automatic loading and unloading device for assembling perforating bullets and an assembly process thereof. The handling robot is arranged on the main frame of the feeding and discharging mechanism, the assembly transfer platform is fixed on the main frame through the installation platform, and the assembly transfer platform is used for Assembling and storing the projectile and the cover ring, the material of the feeding mechanism is transported to the discharging mechanism through the lifting mechanism and the horizontal moving mechanism. The locking mechanism is installed on the discharging mechanism, and the discharging mechanism can slide along the movement direction of the horizontal moving mechanism. The lifting mechanism is used to move the pallet vertically; the handling robot is used to carry the projectile and the cover ring between the lifting mechanism and the assembly transfer platform. The stamping robot is fixed on the main frame and has two degrees of freedom in the vertical plane and a Z The degree of freedom of axis rotation; used to carry the assembled projectile body and cover ring between the assembly transfer platform and the hydraulic press. The invention improves equipment safety, reduces occupied area, has simple structure, is easy to control, and can realize high-efficiency assembly and stamping of perforating bullets.

Description

technical field [0001] The invention belongs to the technical field of assembling perforating charges, and particularly relates to an automatic loading and unloading device for assembling perforating charges and an assembling process thereof. Background technique [0002] The perforating charge is a civil explosive device used to penetrate the casing and connect oil and gas and the wellbore in the process of perforating and completing oil and gas wells. Equipment that is partially suppressed and combined into a perforating charge product. At present, most of the domestic perforating charge manufacturers use imported semi-automatic equipment for the pressing of perforating charges. Compared with the highly automated production lines of foreign perforating charges, the domestic perforating charge pressing equipment generally lags behind in the level of automation. . Manually pre-assemble the type cover, explosive and cartridge case into the hydraulic press. This semi-automat...

Problems solved by technology

[0004] (1) The pick-up device is designed with a linear motion unit. More linear motion units lead to poor structural rigidity. The linear motion unit is fixed on the frame, and the frame occupies too large a volume. Once the device fails, it cannot be installed manually. material space;

[0005] (2) The conveyor belt transports the liner and projectile. During the conveying process, it cannot be guaranteed that the posture of the liner and projectile will not change. The change of posture is a fatal flaw for the assembly of perforating bullets. Therefore, the liner and projectile Not suitable for conveyor belt delivery;

[0007] (4) When feeding the hydraulic machine, the feeding unit needs to place the projectile and the cover ring with the drug-shaped cover in the hydraulic press in sequence; when feeding the hydraulic machine, the feeding unit needs to respectively place the cover ring and the finished projectile in sequence To the temporary storage mechanism, the form of repeated actions leads to insufficient utilization of the potential of hydraulic press production efficiency
