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.

The chain tensioner of the scraper or the chain tensioner of the transfer machine is divided into manual chain fastener and hydraulic chain fastener. By applying certain pre-tightening force to the chain of the scraper, the scraper conveyor can operate safely. When tightening the chain, fix one end of the chain scraper on the side plate of the nose frame or chain chute, and bypass the other end of the chain wheel of the head to make the chain wheel reverse, and then the chain scraper is strained. When the chain tension of the chain scraper is appropriate, the chain scraper will brake to prevent the chain of the chain scraper back loose. After the two chain heads are connected, the chain scraper will remove the brake. The working principle of the chain tensioner is very simple to look at and easy to operate. It is also the spare parts of the scraper that can be purchased in the daily life of coal mine.

It is installed on the connecting cover barrel between the main engine reducer and the motor. When adjusting the hydraulic control valve set during installation, please note: 1. Carefully observe the pressure gauge when adjusting the hydraulic control valve group. As soon as the pressure gauge is out of range, cut off the pressure source quickly to prevent damage to the gauge. 2. The adjustment should be patient and meticulous, and the recommended amount of each adjustment should not exceed 0.5mpa. 3. The hydraulic control valve set should be handled with care to prevent knocking and scratching the anti-rust layer. 4. After adjustment, lock the handle of the pressure reducing valve.

Common hammer head hammer head materials are: high manganese steel, low carbon alloy steel, high chromium cast iron. High manganese steel has better toughness, better technology and lower cost. But the processing hardening of high manganese steel requires higher processing technology. If the impact force is not enough and the contact stress is too small, the surface cannot be hardened. Low carbon alloy steel has high hardness and toughness. At the same working strength, the service time is twice that of high manganese steel. High chromium cast iron has poor toughness and is prone to fracture. High chromium cast iron is usually used as hammer handle on the head of high manganese steel and low carbon alloy steel to make it have hardness and toughness. The quality of manufacturing process is to determine the service life of the hammer head. If there are shrinkage holes or cracks on the surface or inside of the hammer head, it will reduce the performance of the hammer head and even cause fracture in the operation process, affecting the working efficiency. In the manufacturing process of hammer head, forging and heat treatment process should be strictly controlled, and strict quality inspection process should be established. Hammer heads of different structure and geometry have different performance after heat treatment and forging. Generally speaking, the thicker the hammer head, the larger the size, the less easy to penetrate. However, it is limited to change this situation through reasonable heat treatment and forging, so it is still necessary to optimize the structure and shape of the hammer without affecting the use effect. In general, the rotor speed of the broken shaft group is high, the greater the impact force on the hammer head, it can be better impact hardening. But also can cause the hammer head service life to reduce, the crusher power consumption is too big. Therefore, a reasonable speed should be set. If the clearance between crushing shaft rotor, grate, crushing plate and feeding roller is too small, it will lead to the blockage of coal. If the clearance is too small, the crushing effect and efficiency are too low. Hammer head crusher in the use of time, often adjust the clearance between the parts, so that it in the appropriate range. The shape and quality of hammer head directly affect the yield and service life of the crusher. When buying a crusher hammer head, pay more attention to the above mentioned factors, choose suitable for toughness hammer head. Henan Shuangzhi Machinery Equipment Co., LTD. Produces hammer head of crusher, crushing shaft group, scraper conveyor accessories. Welcome customers to purchase.

The crushing shaft is composed of crushing shaft, cutter tooth base, cutter tooth, flat key, bearing, seal and fastening bolt. The strong rival of coal "big block" is broken shaft group, today we are going to introduce this "strong rival"! Trough crusher is used with the transfer machine, using the high speed rotating hammer head to impact and squeeze large raw coal, so as to achieve the required particle size. The crushing shaft assembly is the key component of the crusher, which requires high precision and high stiffness. The middle part of the spindle is equipped with hammer head, which is directly involved in impact crushing. Its performance is the key. Due to the large impact load of the hammer head, high rotation speed, the use of mining is extremely bad, so the performance of the hammer head largely determines the reliability of the crusher.
