Compared with the casting process, the forging process of 17GL7-1 scraper conveyer can make the hardness, strength and service life of the scraper more in line with the service requirements. But the forging process of 17GL7-1 scraper is difficult to be controlled in the actual production process. The following coal manufacturers double zhi machine will give you the introduction of 17GL7-1 scraper forging process of the three points.
1. Heat the scraping slab
The main purpose of heating 17GL7-1 scraper blank is to increase its hardness, toughness and service life. When 17GL7-1 scraping slab is heated and tempered, the oxide layer on the surface of the slab is constantly knocked out to ensure the hardness and toughness of the product, and meanwhile, the smoothness and flatness of the surface of 17GL7-1 scraping slab is also ensured. In the process of shaping the billet, the temperature should be lowered to about 1100 degrees Celsius to achieve a good shaping effect and increase the plasticity of the scraper.
2. Control of quenching temperature
After being heated and tempered, the 17GL7-1 scraper needs to be put into water to be quenched, so that the hardness and strength of the 17GL7-1 scraper are strong. Quenching temperature control is the key and difficult point in the forging process of scraper. Good temperature control can ensure the quality of the scraper and the surface flatness. If the temperature difference is too big, it will lead to the surface of the scraper crack. In quenching, the need to choose the appropriate quenching temperature according to different scraper material. When quenching, field tests should be carried out to control the hardness value. After the scraping plate quenching, but also for the scraping plate residual temperature treatment.
3. Impact energy of a forging hammer
China's scraper conveyor production started late, the initial use of the type of die forging hammer is relatively small, the hardness and quality of the die forging hammer is greatly limited, the impact energy of the die forging hammer is far unable to reach the production of the strike energy required by the scraper. The hydraulic force is then used to increase the impact energy of the hammer. The impact quality of the die forging hammer meets the requirements of the scraper manufacturing, the production of 17GL7-1 scraper quality, hardness can be qualified.
The above is the key and difficult points of 17GL7-1 scraper forging process. Henan Shuangzhi Machinery Equipment Co., Ltd. based on the coal machine industry for many years, mature technology, diversified equipment, the production of coal machine parts forging strength, high hardness, strong toughness, well received by customers, if you have coal machine parts procurement needs, you are welcome to inquire, to visit the factory.
A conveyor belt is a looped belt that is driven by and wrapped around one or more pulleys. It is powered by an electric motor and supported by a metal plate bed or rollers upon which the conveyor belt rests. The pulley that powers a conveyor belt is referred to as the drive pulley and has an unpowered idler pulley.

The gear track of the scraper is installed on the gear track seat of the middle slot, which is the track supported and guided by the shearer. It is an important support point for the stability of normal coal mining for the shearer to realize the haulage of the shearer relying on the tooth and rail pin tooth of the scraper. Therefore, scraper conveyor parts manufacturers remind you to use a more durable scraper conveyor gear track. At present, the teeth and rails of the plate scraper in the market mostly adopt the structural forms such as integral die forging, integral casting, split welding and forging welding. Fission welding type rack and forge welding type rack is a compound structure, by putting the two track plate and pin gear processing compound into an organic whole, due to welding and machining accuracy cannot be guaranteed, so prone to open the phenomenon such as welding, fracture, wear, these two kinds of structure of the rack can't meet the need of the high-power coal winning machine supporting the fully mechanized coal face. Although the whole cast gear track avoids the problem of gear track cracking to some extent, the casting strength obviously fails to meet the use requirements, which affects the coal mining efficiency. The integral die forging gear track is strengthened by heat treatment of alloy structural steel. It adopts die forging technology and completes the manufacturing process by a series of procedures such as forging, forming, trimming and punching. Therefore, the overall strength of the tooth and rail of the scraper is higher than the above three technologies, the pin tooth position and tooth shape processing accuracy is more guaranteed, can make the shearer and the tooth and rail better mesh, the impact force in the use process is also smaller, for the large power shearer, conveyor supporting use to provide a guarantee. The integral die forged gear rail can meet the required performance requirements and is more durable. After reading, you choose and buy which scraper gear rail heart roughly spectrum! Henan Shuangzhi produces various types of gear rail forgings, scraper forgings, sprocket components, etc. If you want to know more, you are welcome to contact us in time.

The scraper produced by Henan Shuangzhi is mostly made of materials of 27SiMn, 40Cr and 40Mn2. After forging, the strength, hardness and toughness of the above three materials are all improved, and the abrasion resistance and bending resistance are also greatly improved. The specific processing technology of scraper is as follows: blanking â?? heating â?? forging blank â?? punching â?? removing burr â?? tempering â?? shot blasting â?? surface treatment â?? quality inspection. Forging process is the key of processing technology. After the blank is heated in the reheating furnace, the blank is made by forging hammer. During the forging process, the oxide skin on the blank surface is knocked off, and the depth and hardness of the hardening layer of the scraper blank are more guaranteed. Henan Shuangzhi supplies the following types of scraper: 101S-01 scraper, 150S0117-1 scraper, 5GL02-2A scraper, 1GL3-1 scraper, 43GL03-1 scraper, 77GL3-1 scraper, 3S001-00/14 scraper, 8GL04-1 scraper, etc. More scraper models can contact us for verification, provide drawings can also provide customized services.

Scraper speed reducer is mainly composed of upper box, lower box, one axis assembly, two axis assembly, three axis assembly, four axis assembly, bearing, gear, seals and so on. At present, the different parts of the scraper reducer are mainly lubricate by grease, oil immersion and splash. The main lubricants of plate scraper reducer are no. 150 extreme pressure gear oil or No. 22 hyperbolic gear oil and No. 2 sodium base grease. The bearings and gears on the second, third and fourth shafts of the scraper reducer are lubricated by splashing oil. Scraper reducer in the oil, follow the strict and accurate principle, can not be mixed with different grades of lubricating oil. Lubricating oil shall be loaded from the top viewing hole when the scraper reducer is being lubricated, and the amount of lubricating oil shall be kept at one third of the circle arc bevel gear. After the new reducer is put into use for 200 hours, the oil inside the reducer should be released, cleaned and changed. After the initial cleaning and oil change, wash and oil change every 1000 hours. When the reducer is working, it should be cleaned and changed for oil when the following conditions occur visually. Oil appears to deposit dirt, particulate sediments. The oil darkens, turns black, and even gives off an unpleasant smell. Brown gelatinous material appears on parts of reducer, corrosion marks appear on the surface of parts. Oil body flow difficulty. There are some situations need to be tested, in the reducer lubricating oil sundry content more than 2%, metal abrasive more than 0.5%, water content more than 2%, the need to clean oil change. In strict accordance with the requirements of the timely scraper reducer lubrication, cleaning and oil change can prolong the cycle of the reducer. Henan Shuangzhi Machinery Equipment Co., LTD. Production reducer, axle assembly, two axle assembly, three axle assembly, four axle assembly, arc bevel gear, if there is a need, you can telephone consultation, Shuangzhi machinery is looking forward to working with you.
