Embodiment Construction
[0024] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0025] see Figure 1-7 , a method for manufacturing a perforating head blank in this embodiment, the steel billet raw material is first spheroidized and annealed, then phosphate surface treated, roughly drawn into a disc, and the roughly drawn disc is subjected to spheroidization annealing, Phosphate film treatment, fine drawing and sizing treatment, and finally the forming process of the perforating head blank in the cold heading forming machine. The inner hole of the perforating head blank produced by this process is completely formed without secondary processing. The specific steps include the following steps :
[0026] (1) The disc round material after precise drawing and sizing is sent into the cold heading forming machine by the feeding wheel and automatically cut into a single perforating head blank; figure 1 shown.
[0027] (2)...

The invention discloses a manufacturing technology of a perforation head blank piece. The manufacturing technology comprises the steps that 1 a wire rod material is cut into a single perforation head blank piece body; 2 the blank piece body is ejected into a female die body of a first die through a punching tool, the two end faces of the blank piece body are upset to be flat and a chamber is formed at the bottom end of the blank piece body through upsetting; 3 the blank piece body is ejected into a female die body of a second die through the punching tool, a locating hole is formed in the front end face of the blank piece body through upsetting, and an inclination is formed at the rear end of the blank piece body through upsetting; 4 the blank piece body is ejected into a female die body of a third die through the punching tool, a countersink is formed in the front end of the blank piece body through upsetting, and a locating hole is formed in the rear end of the blank piece body through upsetting; 5 the blank piece body is ejected into a female die body of a fourth die through the punching tool and a conical hole is formed in the front end of the blank piece body through upsetting; 6 the blank piece body is ejected into a female die body of a fifth die through the punching tool, the roughness of the surface of the conical hole inside the blank piece body is made to meet the requirement and a countersink is formed in the rear end of the perforation end through punching; 7 the blank piece body is ejected into a female die body of a sixth die through the punching tool, a protruding cone of an ejector rod in the female die body and the conical hole of the blank piece body directly penetrate through the second countersink of the blank piece body in a matching mode to poke out residual scrap iron, and then the perforation head blank piece is formed.
Description
technical field [0001] The invention belongs to the technical field of multi-station cold heading, and in particular relates to a multi-station cold heading one-time forming manufacturing method of a perforating head blank. Background technique [0002] The perforating head is used in the perforation operation of oil and gas wells. After working, a channel is established between the production layer and the oil and gas well, so that the oil and gas in the production layer can enter the oil and gas well. At present, the domestic production of this product mostly adopts straight bar or hot heading, and the inner hole must be processed by turning. The process equipment and the comprehensive performance of the product cannot meet the needs of domestic and foreign markets. The production method not only Waste of materials, and the process is complicated, the processing is difficult, the efficiency is low, and the quality cannot be guaranteed accordingly. [0003] In addition, th...
