Problems solved by technology
Most of the current perforating bullet manufacturing enterprises rely on manual weighing methods. This traditional weighing method has an error rate of 2%, and a weighing is completed in an average of 15 seconds. During normal work, two skilled workers can supply one For the normal operation of the press equipment, there are problems such as low weighing accuracy, low efficiency and poor safety. Considering the manufacturing quality, pressing efficiency and safety of perforating bullets, it is necessary to realize unmanned automatic weighing and transmission to meet the perforation High-precision, high-efficiency, safety and automated manufacturing requirements for elastic energy-enhancing covers

Embodiment Construction
[0010] Combine the technical scheme and the accompanying drawings to describe the specific implementation of the present invention in detail: after checking and confirming that the material barrel is filled with powder raw materials, start the feeding device, the air oscillator 7 starts to vibrate, and the metal powder in the material barrel 4 continuously flows to the top. On the tray 14. At the same time, the feeding tray 14 rotates under the drive of the stepping motor 19 to continuously transport the metal powder to the scraper 13 , where the metal powder is scraped into the material cup 15 at the scraper 13 . The scraper 13 continuously scrapes the metal powder into the material cup 15. When the powder quality reaches the set value, the powder feeding plate 14 stops rotating. At this time, the discharge port of the material barrel 4 continues to discharge until the powder under the discharge port accumulates. After a certain amount, the flow head 2 is automatically blocke...

The invention provides a device for automatically weighing perforating bullet energy-accumulation cover powder, which belongs to the field of manufacturing perforating bullets for oil-gas field exploitation, and in particular relates to a device for automatic weighing, automatic detection and automatic spinning of the perforating bullet energy-accumulation cover powder. The device for automatically weighing the perforating bullet energy-accumulation cover powder consists of a feeding device, a powder feeder and a weighing device, and is characterized in that in the feeding device, a charging barrel bracket made of steel plates through welding is welded on a stander, an upper supporting plate of the charging barrel bracket is provided with an upper supporting plate round orifice which is about the size of the diameter of the charging barrel, and a charging barrel is filled in the upper supporting plate round orifice; in the powder feeder, a bearing block is connected to a working table top of the stander through bearing block set screws, and two deep groove ball bearings are filled in the bearing block; and the weighing device consists of an electronic scale, a material cup and a square iron box, and the weighing speed is determined by adjusting the rotating speed of a feeding tray. The device adopts automatic control, improves the weighing working efficiency, has high weighing precision and high reliability, and achieves automated safe production.
Description
technical field [0001] The invention relates to an automatic weighing device for powder of a perforating bullet energy-gathering cover, which belongs to the field of manufacturing perforating bullets used in oil and gas field development, and particularly relates to automatic weighing, automatic detection and automatic spinning equipment for a perforating bullet energy-gathering cover. Background technique [0002] In the manufacturing process of the known energy gathering cover, the weight of its powder raw material is more or less, that is, the weighing accuracy and efficiency have a direct impact on the product quality and manufacturing cost of the energy gathering cover, so in the manufacturing process, its weight must be strictly controlled. Most of the current perforating bullet manufacturing enterprises rely on manual weighing methods. This traditional weighing method has an error rate of 2%, and a weighing is completed in an average of 15 seconds. During normal work,...
