Methods and characteristics of irregular flange processing

Irregular flange machining has many advantages: standard irregular flange machining not only saves space and reduces weight, but more importantly, it ensures that there is no leakage at the joint. The reason for reducing the size of irregular flange machining is to reduce the diameter of the sealing element, which will reduce the cross-sectional area of the sealing surface. Secondly, the flange gasket has been replaced by a sealing ring to ensure that the sealing surface matches the sealing surface. This way, the lid can be tightly compressed with only a small amount of pressure. As the required pressure decreases, the required bolt size and quantity can be correspondingly reduced.

Summary of problems and solutions encountered during flange processing

Due to the function of flange processing, the filling conditions are improved, and gases and non-metallic inclusions are easily discharged from the liquid or metal. The flange processing structure is dense, with fewer defects such as shrinkage, pores, and inclusions, and good mechanical performance. It eliminates or greatly saves metal consumption in casting and riser, and has a high utilization rate of metal equipment. Because the liquid rotates in different ways to generate flange force on the metal, the flange processing technology can improve the filling capacity of the metal, so the flange casting method can be used to produce alloys and thin-wall castings with poor Social mobility.

Detailed explanation of gear processing equipment and process methods

Gear processing equipment is used for metal cutting in gear processing. The gear processing device has a closed frame structure to increase the stiffness and precision of the gear processing device. The gear processing device includes a base, a cylindrical structure, a linear moving device, a second linear moving device, a rotating workbench, and a third linear moving device. Among them, both cylindrical structures and linear moving devices have closed frame structures to reduce overall weight and increase resonance frequency. The gear processing device uses a symmetrical linear motor to drive the linear movement device, and a direct drive motor to drive the spindle head and turntable.

Explain the structural principles of gear machining in detail

For example, uneven tooth pitch can affect transmission efficiency and accuracy. Uneven tooth roots can easily cause other gears to collapse; Uneven gear tooth height can easily cause tooth collapse; Irregular gear size can cause the centerline of the gear to be uncorrected, and the load cannot be corrected. Evenly distributed on the contact surface of teeth, such as wear or scratch, wear, pitting, plastic deformation, etc. Therefore, it is necessary to measure the relevant parameters of the gear and then process the gear to meet high precision applications. In gear processing, there are many different machining machines that produce different gears. Next, let's take a look.

Analysis of the entire process of gear machining

Gear processing technology is the key to obtaining high-quality gears. The working conditions of gears determine the differences in their structure, shape, and accuracy level. In addition to different production conditions, the machining process of gears also varies. However, generally speaking, gear machining can be divided into four stages: rough machining, tooth surface machining, heat treatment, and tooth surface finishing.

What are the prospects of gear processing technology and equipment?

Due to the fact that the CNC system controls each motion axis of the gear machining machine and the links between certain axes, it has the following advantages: it increases the functionality of the machine tool, such as hobbing small taper and drum gears, making it very simple; By shortening the transmission chain and adopting semi closed-loop or full closed-loop control, the positioning accuracy and repeated positioning accuracy of each axis can be improved through CNC compensation, thereby improving the machining accuracy and Cp value of the machine tool and improving its reliability; When replacing products, the gear trimmer saves the calculation and time of variable speed gears and differential variable speed gears, feed and spindle gear speed changes, and the replacement time of inclined guide rails, thereby reducing auxiliary processing time and increasing the flexibility of gear processing machines; With the simplification of the mechanical structure, it can be designed to improve the rigidity of the machine tool and minimize thermal deformation to the greatest extent; There is no mechanical connection between the shafts, making the structural design very typical, which is more conducive to the implementation of modular design and manufacturing. The high-speed operation of gear processing machines such as hobbing machines, shaping machines, and grinding machines mainly refers to the high spindle speed and workbench speed of the machine tool, which are the main indicators to improve cutting efficiency.
