Problems solved by technology

[0003] At present, most domestic manufacturers of perforating bullets use semi-automated equipment imported from abroad to manufacture perforating bullets. The press-fitting equipment generally lags behind in terms of automation level, and there is a big gap in technology
Semi-automated production restricts production efficiency and product quality stability, and there are greater safety hazards due to the involvement of high explosives

Embodiment Construction

[0032] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like parts throughout.

[0033] refer to Figure 1 to Figure 4 According to the present invention, the fully automatic press-fitting equipment mainly includes a frame 1, at least two sets of conveyor belts, a pick-up device and a control system.

[0034] The frame 1 can be made of various steel frames, etc., and is used to support the conveyor belt and the pick-up device.

[0035] The fully automated press-fitting equipment may specifically include two sets of conveyor belts to respectively convey the liner Y and the projectile body D used for press-fitting the perforating charge, wherein the projectile body D is a combination of explosives and shells. The structure of each group of conveyor belts is the same, and can include an upper conveyor belt 3, a lower conveyor belt 2 and a lifting conveyor...

Abstract

The invention discloses a press fitting method for perforating bullets. The press fitting method includes the steps that A, cartridge-shaped covers and bullet bodies are placed on at least two sets of conveyor belts of a full-automatic press fitting device and the cartridge-shaped covers and the bullet bodies are conveyed to the picking positions through the conveyor belts; B, the cartridge-shaped covers and the bullet bodies are picked through a picking device of the full-automatic press fitting device; C, the picked cartridge-shaped covers and bullet bodies are put in a press machine to form the perforating bullets; D, the formed perforating bullets are placed on one set of conveyor belts and the step B and the step C are repeated simultaneously till the cartridge-shaped covers and the bullet bodies on the conveyor belts are completely formed into the perforating bullets; and E, the formed perforating bullets are conveyed through the conveyor belts. By the adoption of the press fitting method, the full-automatic press fitting operation of the perforating bullets is achieved, and production efficiency, the safety of the press fitting process and the quality stability of products are improved.

Description

technical field [0001] The invention relates to the field of perforating bullet manufacturing, in particular to a method for realizing automatic press-fitting of perforating bullets. Background technique [0002] Perforating charge is a civil explosive device used to penetrate the casing and communicate oil gas and wellbore during the perforation and completion of oil and gas wells. It includes three parts: liner, explosive and shell. The perforating charge pressing equipment Equipment that combines three-part pressing into a perforating charge product. [0003] At present, most domestic manufacturers of perforating bullets use semi-automated equipment imported from abroad to manufacture perforating bullets. The press-fitting equipment in China is generally backward in terms of automation level, and there is a big gap in technology. Semi-automated production restricts production efficiency and product quality stability, and there are greater safety hazards due to the invol...
