The dumbbell pin plays an important role in the normal operation of the scraper conveyer as the connecting member between two adjacent chutes. Today the coal machine parts manufacturer Henan shuanzhi will introduce the dumbbell pin of scraper conveyer for you. Scraper conveyor dumbbell pin shape is like "fitness dumbbell", the middle is thinner, thicker at both ends. The dumbbell pin jams the ends of the two adjacent middle slots by the thicker ends at each end and connects the two adjacent middle slots by the thin middle rod. In addition to the common dumbbell pins described above, there are two types of special shaped dumbbell pins - I-type dumbbell pins and day-type rings. The stress condition of dumbbell pin is more complicated. In the process of hydraulic support moving the middle trough, the dumbbell pin will be pulled by the adjacent middle trough and subjected to shear stress because the adjacent chute is not synchronized. The dumbbell pin of scraper conveyor is a vulnerable part, and the common fault is fracture. The first crack occurred in the neck of the dumbbell pin, mainly because the neck of the dumbbell pin is a region where stress concentration is relatively large. Under long-term working conditions, the dumbbell pin's neck crack growth area diffused to a certain extent, resulting in fatigue fracture, resulting in the fracture of the whole dumbbell pin. Once the dumbbell pin is broken, it will cause the middle slot dislocation or off, the scraper chain is affected by it, easy to break the chain, the chain clip, from the chute off the phenomenon, affecting the scraper conveyor working surface production safety and normal production. Above is the dumbbell pin on the scraper conveyer, do you know? The dumbbell pin of the scraper conveyer produced by Henan Shuangzhi is forged from the selected material of 40Cr, and the quality is comparable to that of the original products after multiple processes such as tempering and quenching. More scraper parts, transfer machine parts, hydraulic bracket parts related product models, product information, you are welcome to consult.
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.

Reducer has the characteristics of large bearing capacity, high transmission efficiency, generally used for input shaft and output shaft are arranged in a vertical direction of the transmission device. For the coal mine scraper reducer oil leakage of the reasons are usually only two points: sealing ring damage and the box body joint surface is not strict. Most of the oil leakage of the scraper reducer is caused by the damage of the sealing ring. After long-term operation and the influence of underground coal mine environment, the sealing ring will inevitably wear down, resulting in poor sealing effect and oil leakage. However, it can be well solved by simply replacing the sealing ring. For the box body joint surface lax than the former slightly less, this situation is mostly the upper and lower box body lax, the end pressure cap is not tight, may be caused by the assembly irregularities, may also be caused by the long-term operation of bolts loose, the solution is to tighten all parts of the bolts.
