Types and differences of wheels

2023-07-31

The steel wheel is made by welding the rim and the spoke and then painted. It is equipped with an inner tube tire. The elastic retaining ring (or retaining ring and lock ring) is assembled at the same time when the tire is assembled. At present, it is widely used in medium and low-grade buses, light and heavy trucks (especially dump trucks). The cross-sectional shape of the rim (including the retaining ring) is rolled by a steel mill. The rim is mainly processed by coiling, welding (butt welding) and other processes, of which butt welding is the key process; the spokes were originally stamped and formed. At present, they are mainly processed by spinning, blanking, machining and other processes, of which spinning is the key process. The advantages of this product are that the process is relatively simple and the product has a strong carrying capacity,

Analysis of Jilin punching die hard material efficient processing know-how

Challenge: How to become a more competitive supplier of Jilin punching dies. Solution: Use every opportunity to reduce the processing time of mold parts. Stamping dies for processing metal plates account for a large part of the dies, and most of the stamping dies are used in the automotive industry. The automobile industry and mold manufacturers have higher and higher requirements for the production efficiency of stamping dies. Because Jilin punching dies have a large number of processing operations, they have the potential to improve efficiency. Stamping die is a complex stamping tool. Many parts need hard and durable materials, and the efficient processing of these materials requires the correct cutting tools and processes. However, most of the processing operations in the production of stamping dies are only general metal cutting of basic materials, and a small amount of processing operations are more complex tool steel and ductile iron three-dimensional profiling processing. Although both of these processing methods have the potential to increase productivity, stamping die manufacturers often ignore general processing. In the past few years, metal cutting ability and performance have been significantly improved, and the processing time and cost of many mold factories have been reduced by half. However, even with state-of-the-art production technologies, there is still room to improve production and even increase processing efficiency by up to 20%. To become a successful automotive stamping die manufacturer, you need to take a long-term strategy, focusing on the processing time and machine standby time of the mold parts on the machine tool, as well as the type of machine tool. However, there are a large number of short-term strategies that can have a direct effect on old and new machine tools. These strategies exist in all types of machining processes, and some of them also affect subsequent operations, such as additional operations, mold polishing and assembly. By shortening the processing time of each clamping, reducing the downtime and the number of tool changes, the manufacturing time of the stamping die can be shortened. The safety of modern CNC machining methods, coupled with the most advanced cutting tools, basically eliminates errors, so whether the delivery cycle of Jilin punching die can be accepted by users should be the decisive factor.

China's Machine Tool Industry Must Solve Three Major Problems

2023-07-31

From 2001 to 2004, the world's machine tool output value was US $36.13 billion, US $32.16 billion, US $36.79 billion and US $45.29 billion respectively, and increased by 14.4 and 23.3 respectively in 2003 and 2004 compared with the previous year. With the improvement of the world economic situation, the market demand for machine tools has increased, and the competition in machine tool technology has become more intense. Under the new situation, China's machine tool industry must comprehensively improve product quality; adjust product structure to meet the urgent needs of all aspects of the market; reduce imports, expand exports, and effectively solve these three major problems. Quality problems for a long time, the world's machine tools in

Several Problems in the Transformation and Upgrading of China's Machine Tool Industry

2023-07-31

Machine tool is the basic equipment for processing and manufacturing all industrial equipment, and it is the core department of equipment manufacturing industry. Among them, high-end CNC machine tools for processing various precision and complex parts are the strategic highlands for the forefront of industry technology and the competition of various industrial powers. At present, the trend of machine tool manufacturing industry at home and abroad is: precision (static accuracy and machining motion accuracy, monitoring and compensation of thermal deformation/vibration, machining accuracy up to sub-micron level), high speed, composite (one-time card loading to complete all process processing), intelligence (fusion of information and robot technology, self-perception and analysis of processing status and environmental information and take countermeasures), green (energy saving and consumption reduction, noise control

Why Does Jilin Punching Die Have Burr in Die Industry?

2023-07-31

With the all-round development of modern mechanization, more and more people engaged in the mold industry (mold is also called fitter) are facing more and more problems, and the country's environmental protection is also paying more and more attention. To get a good environment, it is necessary to start from the first layer, that is, the quality of mold production is getting higher and higher, but the more problems it faces. The following is a brief explanation of the burr problem of a single punching die: a single punching die should be relatively the simplest die, the only problem is burr, other problems are some minor problems. There are many reasons for burrs, such as the following: 1. The material of the material is the same now, because the material of the material itself will be related to the price you purchase. Of course, there are few burrs when you buy good materials, but this is one of the reasons. If you don't say that if you buy good materials, you won't have burrs. The material of the materials is only one of the reasons for burrs. There is a certain gap after each kind of material. you should put the gap according to the thickness of the material you want to drop. this is mainly the designer's business. we should also give him the last level. we don't care about the assembly. in fact, we will replace and repair it in the end. 3 Assembling the extension die Of course, this is one of the fitter's best techniques. We need to make the gap the same size on all sides so that there will be no burrs. This should also be a difficult side. The reason why it is difficult to show the technology is right? 4 Cutting edge No matter what similar die, as long as the cutting edge is not fast, or collapsed, it is useless, because you will continue to cut. There will be burrs and so on, the most common is these two, so this is one of the main reasons. This kind of work has both skills and coolies, so few people generally work for a long time or are very proficient. This is the backbone of a factory, so fitters should belong to logistics in the company.

The purpose and significance of the project research mold is the foundation of the current industrial development, carrying and supporting all the industrial development. In today's industrial development, no matter which industry and which variety are inseparable from the role of the mold, such as: automotive, electronics, food production and processing industries and fields, are inseparable from the mold. Due to the different industries and products, the mold also exists in a variety of ways, and its types are also diverse. Traditionally, there are: stamping, shearing, punching, stretching, forming, etc. applied to various uses of the mold. The type of die often used in the processing of punching die room products, by punching the needle to the material belt or workpiece.
