　　The security inspection machine is an electronic device that uses a conveyor belt to send the checked luggage into the X-ray inspection channel to complete the inspection. When the luggage enters the X-ray inspection channel, it will block the package detection sensor, and the detection signal will be sent to the system control part, generating an X-ray trigger signal, triggering the X-ray source to emit an X-ray beam.

　　

　　The X-ray beam passes through the inspected objects on the conveyor belt, and the X-rays are absorbed by the inspected objects and finally bombard the semiconductor detector installed in the channel. The detector converts the X-rays into signals, and these very weak signals are amplified and sent to the signal processing chassis for further processing. After these signals are processed, they are displayed on the display screen.

　　

　　”No matter how many layers a package has, X-rays can penetrate it and display the items in the package layer by layer.” Dangerous items are identified by different colors. Multi-energy colored organic matter is displayed in orange, inorganic matter is displayed in blue, and mixtures are displayed in green. High energy/low energy are switched to display. High energy displays metals, etc., and low energy displays non-metals. In the image display system, the X-ray sensor L-shaped photodiode array detector (multiple energies are optional), 12-bit depth, high penetration display increases the brightness of dark areas in the image, so that items hidden behind highly absorbent objects are clearly displayed. Low penetration display increases the contrast of low absorption (easy to penetrate) objects, making easy to penetrate objects clearer; therefore, the X-ray security inspection machine is not a decoration, but actually undertakes the work of protecting railway safety.

　　

　　So how does the security inspection machine detect these dangerous items?

　　

　　1. Image monitoring method

　　

　　Image monitoring method directly determines the object from the X-ray image configuration. Therefore, whether the object is suspicious depends on the image on the monitor or display. Unusual objects or objects with different shapes that appear on the display or monitor should be considered suspicious objects. Objects that cannot be accurately identified should also be considered suspicious objects and need to be carefully investigated. The image can be located and analyzed as needed.

　　

　　2. Color analysis method

　　

　　The color analysis method is to identify the type of material based on the different colors that different materials show under the x-ray image. The various colors that appear on the monitor are a reflection of the density, quality and quantity of the object. Therefore, the quality of the object can be evaluated based on the depth of the image color.

　　

　　Light yellow is generally the color of a single piece of clothing, thin plastic, and a small amount of paper.

　　

　　Orange is generally the color of soap, soap, explosives, drugs, wood, leather products, etc.

　　

　　Dark orange is generally the color of a large number of books, paper, RMB, high-concentration liquids, large bags of rice and flour, etc.

　　

　　Blue is the color of inorganic substances such as copper, iron, and zinc. Thick cables, stun guns, bullets, gun barrels, guns, and knives show different shades of blue. Green is the color of mixtures, stainless steel products, cables, etc. show different shades of green. Red is the color of impenetrable objects, mostly heavy metals and thick objects.

　　In the fastener forming process, cold heading (extrusion) technology is a main processing technology, which belongs to the category of metal pressure processing. In production, at room temperature, external force is applied to the metal to form the metal in a predetermined mold. This method is usually called cold heading. In fact, the forming of any fastener is not only achieved by cold heading. In the cold heading process, in addition to upsetting deformation, it is also accompanied by positive and negative extrusion, compound extrusion, punching, rolling and other deformation methods. Therefore, the name of cold heading in production is just a habitual name. To be more precise, it should be called cold heading (extrusion).In view of the actual needs of society, non-standard fasteners price We need to change some original problems to better serve the society and benefit people. https://jieruifasteners.com/

　　

　　Cold heading (extrusion) has many advantages, and it is suitable for mass production of fasteners. Its advantages can be summarized as follows:

　　

　　High steel utilization rate. Cold heading (extrusion) is a method with little or no cutting. For example, when machining hexagonal bolts and cylindrical hexagon socket screws of rod type, the steel utilization rate is only 25% to 35% by cutting method, while by cold heading (extrusion), its utilization rate can be as high as 85% to 95%, which is only some process consumption of material head, material tail and cutting hexagonal head edge.

　　

　　High productivity. Compared with general cutting processing, the efficiency of cold heading (extrusion) is more than dozens of times higher.

　　

　　Good mechanical properties. The strength of parts processed by cold heading (extrusion) method is much better than that of cutting processing because the metal fiber is not cut off.Suitable for automated production. Fasteners (including some special-shaped parts) suitable for cold heading (extrusion) method are basically symmetrical parts, suitable for production by high-speed automatic cold heading machine, and also the main method of mass production.

　　

　　In short, the cold heading (extrusion) method for processing fasteners and special-shaped parts is a processing method with a very high comprehensive economic benefit. It is a processing method commonly used in the fastener industry. It is also an advanced processing method that is widely used and has great development both at home and abroad.

　　

　　Cold heading, cold pressing:

　　

　　At room temperature, the blank is placed in the mold of an automatic cold heading machine or a press, and pressure is applied to the mold. The relative movement of the upper and lower molds is used to deform the blank in the mold cavity, reduce the height, and increase the cross section. This pressure processing method is called cold heading for automatic cold heading machines and cold pressing for presses. In actual production, the cold forming process of fasteners is often accompanied by extrusion during the cold heading process. Therefore, the cold heading process of fastener products is actually a composite processing method that has both cold heading and extrusion.

　　

　　

　　Deformation methods of cold heading (extrusion):

　　

　　1. Punching. Separate part of the blank from the main body, such as cutting of wire, punching of nuts, trimming of the head of hexagonal bolts, etc.

　　

　　2. Upsetting. A processing method that shortens the height of the blank and increases the cross-section, such as ball upsetting of nuts, pre-upsetting and fine upsetting of bolt head forming, etc.

　　

　　3. Positive extrusion. During cold heading, when the blank is deformed in the lower die, the flow direction of the metal is consistent with the movement direction of the upper die. The reduction of the thick rod in cold heading bolts and cylindrical head hexagon socket screws is a positive extrusion.

　　

　　4. Reverse extrusion. During the deformation of the blank, the flow direction of the metal is opposite to the movement direction of the upper die. The head forming of the cylindrical head hexagon socket screw belongs to reverse extrusion.

　　

　　5. Compound extrusion. During the deformation of the blank, part of the metal flow direction is the same as the movement direction of the upper die, and part is opposite to it, that is, there is both positive extrusion and negative extrusion during the deformation. For example, the cylindrical head hexagon socket screw has both rod diameter reduction (positive extrusion) and head forming (negative extrusion) during the deformation at the same station.
