信息詳情：
n terms of sharpness, the steel hardness is higher, the cutting edge degree is smaller, and the edge radian is softer, and the kitchen knife with nonlinear straight drop is sharper and better to use, especially the slicer. generally, the cutting edge of a slicing knife with a hardness of more than 56 is 10-20 degrees, and that of a bone chopper is 25-35 degrees. therefore, a slicer made of the same material and technology must be sharper than a bone chopper. therefore, when choosing a kitchen knife, you should not only consider the material, but also the cutting edge degree. generally, the hardness of the tool edge is 56 + hrc, 58 + hrc steel is very good, and 60hrc is the hardest. only too high hardness is easy to break, so moderate hardness is necessary, excessive can not. it's just too low!

簡介：the most reasonable way to produce steel spade in batch is to use sheet metal for stamping. even if the single piece is processed by hand, it is also the most convenient to cut and process with sheet metal. except for low carbon steel, all the steel products in shanghai are wear-resistant, but the hardness of medium carbon steel in other varieties is worse. the question is whether there are ready-made plates for "track steel" and "tool steel"? manganese steel plate processing can be considered as a better material, but the cost will be very high. the brittleness of high carbon steel is greater than that of medium and low carbon steel. combined with the application situation and price of the product itself, low carbon steel plate should be used. after forming, the surface of the steel shovel should be carburized. in this way, the surface hardness of the steel shovel can reach the level of high carbon steel, wear-resistant, and the interior has enough toughness. and the cost is low. the coating on the surface of steel spade is used for surface decoration and rust prevention. ordinary black paint is also the influence of ordinary paint on people and environment. once used, the coating will be worn off. if it is used in the food industry, stainless steel tools can be used with higher requirements, which will be safer and better.

簡介：the most reasonable way to produce this kind of product in batch is to use plate for stamping. even if it is processed by hand, it is most convenient to cut and process with plate. except for low carbon steel, the steel in the title is resistant to wear, but the hardness of medium carbon steel is worse in other varieties. the question is whether there are ready-made plates for "rail steel" and "tool steel"? manganese steel plate processing can be considered as a good material, but the cost will be very high. high carbon steel is more brittle than medium and low carbon steel. combined with the application situation and price of the product itself, low carbon steel plate should be used. after forming, the surface hardness of steel spade can reach the level of high carbon steel, wear-resistant, and the internal has enough toughness. and the cost is low.
the coating on the surface of steel spade is used for product surface decoration and rust prevention. ordinary black paint is the impact of ordinary paint on people and environment. once used, the coating will be worn off. if it is used in the food industry, the requirements are higher, stainless steel tools can be used, which is safer and easier to see.
標(biāo)題：technology of making steel spade based on continuous cold stamping die
時間：2020.12.06.17:33
簡介：the invention relates to a manufacturing process of hardware tools, in particular to a process for manufacturing steel spades based on a continuous cold stamping die. the strip steel coil is placed in the strip uncoiler, and then the strip steel is leveled by the temper mill. the leveled strip steel enters the feeder, and the feeder delivers the material to the press according to the set length. after entering the press, the strip steel passes through seven working sections of the continuous cold stamping die in turn, and then the formed spade is quenched, antirust treated and packed. the production efficiency is obviously improved, and the labor cost is greatly reduced. the traditional process requires about 10 people to complete the work, and the invention can be easily completed by only 1 to 2 people. the whole spade body forming process can be smoothly formed without heating, thus greatly reducing the energy consumption and environmental pollution.
