Cold And Warm Forging Forming Process Of Mining Pick Tooth Body Blank
Cutting Picks are also called mining drill bits or drill bits for mining. Mining picks are one of the vulnerable parts of coal mining and roadway excavation machinery. They are the main cutter tools for coal falling and crushing.
The economic performance of the cutting picks directly affects the utilization of coal mining machinery’s production capacity, power consumption, working stability, and the service life of other related parts and components.
When cutting coal and rock, the pick bears high periodic compressive stress, shear stress, and impact load. Although the hardness of coal is not very high, it often encounters hard mineral materials like coal gangue. The construction of these cutter tools must, therefore, take into consideration properties that will make them withstand harder surfaces than coal.
Impact due to hard material also causes the temperature of the pick to rise. Therefore, picks that work under such complex conditions requires the cutter body to have both abrasion resistance and good impact resistance. Otherwise, these cutter tools may not deliver in such conditions as expected.
Milling pick body is usually made of 4140 or 4130 material, which are high grades of steel alloys. The processes used for the construction of the body are cold forging and warm forging technologies. The incredible mechanical properties that cold and warm forged steel offers are the reason forging is the most popular forming technology today.
After the cold forging process, the pick body has the advantages of fine grain size, good heat treatment performance, small machining allowance, and high batch production. The fine grain size is a key factor that increases the hardness and strength of the forged cutting pick body. That’s why cold-forged or warm forged pick body blanks can withstand impact and heat damages.
The small machining allowance feature enables the manufacturer to reduce the cost of finishing. The cold and warm forging processes produce near net-shaped forgings. Therefore, the need for finishing is very small, which helps in the reduction of the production cost. The benefits cascade downwards where buyers can get these cutter tools at a lower price.
The other advantage of the cold and warm forging is the high batch production. These forging processes enable mass production of the mining pick tooth body blanks. The production setup uses dies, and once set, it can shun out thousands of homogenous pick bodies. Important to note is that the cold and warm forging process produces cheaper, high-quality mining picks tooth body blanks.
