An automatic loading and unloading device for perforating charge assembly

Abstract

The invention discloses an automatic feeding and discharging device for perforating bullet assembling. An assembling transferring mechanism is used for assembling materials and storing the materials temporarily; a four-shaft industrial robot is arranged between a material supplying and storing mechanism and the assembling transferring mechanism, and used for carrying the materials between the material supplying and storing mechanism and the assembling transferring mechanism; a punching robot is arranged between the assembling transferring mechanism and a hydraulic machine, and used for carrying the materials between the assembling transferring mechanism and the hydraulic machine; and a wall is arranged between the punching robot and the hydraulic machine. The feeding and discharging devicereduces the frequency of manual feeding and discharging, and is high in efficiency, wide in movement range, simple in structure and easy to control.

Description

technical field [0001] The invention belongs to the technical field of perforating charge assembly, and in particular relates to an automatic loading and unloading device for perforating charge assembly. Background technique [0002] Perforating charge is a civilian explosive device used to penetrate the casing and connect oil and gas to the wellbore during the perforation and completion of oil and gas wells. It includes three parts: liner, explosive and shell casing. Equipment that is partially pressed to form a perforating charge product. At present, most domestic perforating charge manufacturers use semi-automated equipment imported from abroad for the press-fitting of perforating charges. Compared with the highly automated foreign perforating charge production lines, domestic perforating charge press-fitting equipment generally lags behind in terms of automation. . Manually pre-assemble the liner, explosives and shell casings and put them into the hydraulic press. This...

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, no manual loading is reserved Space;

[0005] (2) The conveyor belt transports the liner and projectile. During the conveying process, it cannot be guaranteed that the attitude of the liner and projectile will not change. The change of posture is a fatal defect 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 place the cover ring and the finished projectile respectively in sequence To the temporary storage mechanism, the form of repeated actions leads to insufficient utilization of the potential of hydraulic press production efficiency
