Embodiment Construction

[0011] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0012] A cutting machine transmission device, comprising: a combination of quenched and tempered steel, nodular cast iron and tungsten, wherein the quenched and tempered steel accounts for 40%-44% of the mass percentage of the cutting machine transmission device, The said nodular cast iron accounts for 20%-23% of the mass percentage of said cutting machine transmission device, and said tungsten accounts for 36%-37% of said cutting machine transmission device's mass percentage.

[0013] different from the prior art.

[0014] In another embodiment, the quenched and tempered steel accounts for 42% of the mass percentage of the cutting machine transmission device.

[0015] In another embodiment, th...

Abstract

The invention discloses a transmission device for a cutting machine. The transmission device is characterized by being compounded by the following components in percentage by mass: 40%-44% of hardened and tempered steel, 20%-23% of spheroidal graphite cast iron and 36%-37% of tungsten. By adopting the above mode, the mechanical performance of cast iron can be effectively improved, and especially the plasticity and the tenacity of the cast iron are improved, so that the strength which is higher than the strength of carbon steel can be obtained.

Description

technical field [0001] The invention relates to the field of cutting machines, in particular to a cutting machine transmission device. Background technique [0002] Ductile cast iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. It is based on its excellent performance that it has been successfully used to cast some complex stress, strength, toughness, and wear resistance. Parts with high performance requirements. Ductile iron has rapidly developed into a cast iron material that is second only to gray cast iron and is widely used. The so-called "substituting iron for steel" mainly refers to ductile iron. [0003] Cast iron is an iron-carbon alloy with a carbon content greater than 2.11%. It is obtained from industrial pig iron, scrap steel and other steel and its alloy materials through high-temperature melting and casting. In addition to Fe, it also contains carbon in other cast iron that is precipit...
