Production Process

Since the 1990s, the domestic electric tool industry has formed a number of large-scale enterprises, with great progress in technology and technology, continuous improvement in product quality and performance, and huge production capacity, which also drives component manufacturers. With the continuous improvement of the global competitiveness of China's manufacturing industry, China has become the most important exporter of the international power tool market.

The electric tool industry belongs to the advanced equipment manufacturing industry, and the advanced manufacturing in the service is enhanced. Electric tools are widely used in aerospace, high-speed rail construction, shipbuilding, automobiles, and other advanced equipment manufacturing and road construction, decoration, wood processing, metal processing and other production fields. Common power tools are: metal cutting power tools, grinding power tools, assembly power tools and railway power tools. Commonly used electric tools include electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, electric planers, etc. Powder metallurgy parts are widely used in power tools.

Electric hammer cylinder gear sleeve PM sintered part Machining process of powder metallurgy parts: Many powder metallurgy mechanical parts have grooves, transverse holes, threaded holes, etc. in the vertical pressing direction, and high dimensional accuracy and geometric tolerance accuracy (coaxial Degree, verticality, etc.), the molding method is difficult to achieve, or it is expensive to try to achieve. Therefore, it is usually achieved by cutting, and it is still economically calculated. The cutting process of powder metallurgy parts should pay attention to the following two problems: 1. The working surface of powder metallurgy parts (such as the inner hole of oil bearing, etc.) should not be processed by grinding or grinding. Because abrasive particles and the like may invade the gap during the grinding process, the lubricating oil contained in the parts is not easy to seep out during work, which affects the service life. 2. When cutting electric hammer cylinder gear sleeve PM sintered part powder metallurgy parts, try not to use coolant. In special cases (such as tapping, etc.), light vegetable oil can be used as cutting fluid. If it is necessary to use cooling liquid (such as saponified liquid for grinding, etc.), the parts must be cleaned after processing, and can be cleaned with hydrocarbons with a higher boiling point (such as BP-ethane, etc.), or ultrasonic cleaning. After cleaning, the parts are dried at a temperature above 100°C to remove the residual coolant in the gap. Then vacuum dip anti-rust oil to prevent parts from rusting. Generally, if powder metallurgy parts require machining technology, an appropriate amount of cutting agent should be added when mixing raw materials to prevent defects such as sticking, overheating, and slow feed during machining. The main machining methods of powder metallurgy parts are: turning and boring, powder metallurgy sintered structural parts products, planing and milling, powder metallurgy sintered structural parts products, drilling and reaming, tapping, grinding and extrusion. The anti-rust packaging selected for powder metallurgy parts does not need to be oiled, the anti-rust effect is good, and the operation is very simple, and there is no need to clean it later.

Can powder metallurgy structural parts be machined? Most parts are only "near final shape" and require some sort of finishing. However, compared with castings and forgings, powder metallurgy parts are very wear-resistant and difficult to process, which also forms the promotion effect of metallurgical powder manufacturing. Parts are not as easy to machine as ordinary steel, mainly because of the microscopic fatigue of the cutting edge caused by porosity. The cutting edge cuts in and out of the powder metallurgy part, where it passes between the grain and the hole. Repeated small impacts cause small cracks in the cutting edge. These fatigue cracks grow until the cutting edge chipping. In order to improve the machinability of powder metallurgy parts, some companies have developed special grades of steel powder, and some Chinese companies have also formulated their own formulas to improve the machinability of powder metallurgy structural parts.
