Automatic assembly mechanism for perforating bullet

Abstract

The invention provides an automatic assembly mechanism for a perforating bullet. The automatic assembly mechanism is characterized in that a powder liner (arranged on an upper-layer conveyor belt) and a casing filled with an explosive (arranged on a lower-layer conveyor belt) are respectively taken from an dual-layer plane turning loading conveyor belt 1 by a dual-claw pneumatic loading mechanical arm 3; the casing and the powder liner are sequentially placed in a hydraulic press 4; after the casing and powder liner are compressed by the hydraulic press, a product is taken down by a pneumatic product-taking mechanical arm 6 and is placed into a die 2 of a plane turning product-taking conveyor belt 7. According to the automatic assembly mechanism disclosed by the invention, the assembly process of loading, conveying, pressing explosive and taking product is realized, the safety coefficient is improved, the work condition of a production line can be monitored by an isolating explosion-proof wall window 5 while the isolation of an operator and an explosive pressing scene is ensured, potential safety hazards are eliminated and the assembly precision and efficiency are improved. The automatic assembly mechanism is suitable for assembly and production of perforating bullets in the petroleum industry.

Description

Technical field [0001] The invention relates to an automatic assembly mechanism, in particular to an automatic assembly mechanism for a perforating ammunition pressing process. Background technique [0002] Petroleum perforating bombs are used to communicate oil well casings and oil and gas layers, creating a channel for oil and gas flow between oil well casings, cement rings and oil and gas layers, so that oil and gas can enter the oil well casing along this channel. Therefore, oil perforating bombs are Important explosive equipment in the development of oil and gas fields. [0003] Petroleum perforating bombs are mainly composed of a powder type cover, a shell and an explosive. The powder type cover is pressed into the shell containing the explosive by a hydraulic press to complete the assembly of the oil perforating bomb. The existing assembly production line manually puts the shell and the powder charge type cover into the hydraulic press, and the operator exits the site to st...

AI Technical Summary

Problems solved by technology

[0004] 1. It is difficult to guarantee the safety of the operator

Due to the possibility of explosive explosion under the high pressure of the press, the operator manually completes the process of placing the shell and powder powder cover, starting the press and taking away the finished product on site. The isolation guarantee between the operator and the product is insufficient, and the operation There is a possibility of misoperation by the operator, so the production line has potential safety hazards that cannot be ignored, posing a threat to the life safety of the operator and the protection of the production line.

[0005] 2. Assembly accuracy is difficult to be guaranteed

Since the positioning method of the shell and the powder medicine cover is mainly realized by manual installation and adjustment, the positioning error caused by human factors and environmental factors is relatively large, which affects the assembly quality

[0006] 3. Assembly efficiency is difficult to be guaranteed

Due to the stage of pressing the charge, the operator has to repeatedly place the shell and the powder drug cover, then exit the site to start the press, and then return to the site to take the finished product. It takes a long time to assemble a single petroleum perforating charge, and the labor intensity is high, resulting in low assembly efficiency.

[0007] The existence of the above problems is not conducive to the improvement of automation level and production efficiency, the assurance of safety and assembly quality, and the reduction of costs of the petroleum perforating bullet assembly production line.
