Problems solved by technology

[0009] The purpose of the present invention is to overcome the relatively poor quality of the existing slitting knives in our country, which is difficult to meet the needs of use. When processing some products with high quality requirements, we can only rely on imported foreign knives, which makes it difficult and expensive to repair the knives in the later stage. Insufficiency of the invention provides an inlaid alloy high-performance shearing circular knife and its processing method

According to the use characteristics and requirements of the shearing circular knife, the knife ring 13 and the knife body 14 are respectively set to two different mate...

Embodiment 2

[0087] A high-performance round shearing knife inlaid with alloy in this embodiment includes a knife ring 13 and a knife body 14 , and the knife ring 13 is fixed on the outer peripheral surface of the knife body 14 . In this embodiment, two L-shaped annular steps are processed on the outer peripheral surface of the cutter body 14, and the two cutter rings 13 are respectively set and fixed on the L-shaped annular steps by inlaying, thereby processing a double-sided knife edge. shearing round knife. The cutter body 14 of the present embodiment adopts spring steel material, and the composition and mass ratio of the spring steel material used are: C: 0.62-0.7%, Si: 0.17-0.37%, S≤0.035%, Mn: 0.9-1.2% , Cr:≤0.25%, P≤0.035%, Ni≤0.25%. The cutter ring 1 is made of a powder metallurgy blank, and the raw material components of the powder metallurgy blank are: WC 82%, Co 15%, W, Ni, Cr 3 C 2 , VC, Mo 2 C, TaC 3%, among them, Cr 3 C 2 , VC, Mo 2 The mass percentages of C, TaC, Ni, ...

Embodiment 3

[0107] An inlaid alloy high-performance shearing round knife of this embodiment is similar to that of Embodiment 1, the difference is that the raw material components of the knife ring blank of this embodiment are calculated by weight percentage: WC 80%, Co 15%, W, Ni, Cr 3 C 2 , VC, Mo 2 C, TaC5%, among them, Cr 3 C 2 , VC, Mo 2 The mass percentages of C, TaC, Ni, and W are 0.4%, 0.3%, 1%, 0.5%, 0.3%, and 2.5%, respectively.

[0108] The processing method of the above-mentioned inlaid alloy high-performance shearing circular knife of the present embodiment, its steps are:

[0109] Step 1. Preparation of knife ring raw materials:

[0110] Weigh the raw materials of the powder metallurgy blank for processing the knife ring 13 according to the mass percentage requirements;

[0111] Step 2, blank preparation of knife ring:

[0112] Mix the components weighed in step 1 and put them into a wet mill for wet milling. The wet milling medium is alcohol, and the mass ratio of al...

Abstract

The invention discloses an alloy-inserted high-performance shearing circular knife and a processing method thereof, and belongs to the technical field of tool processing. The shearing circular knife comprises a knife ring and a knife body, wherein the knife ring is fixedly arranged on the outer circumferential surface of the knife body in a sleeved manner; the knife body is made of a spring steel material; and the knife ring is prepared from powder-metallurgy blank. The powder-metallurgy blank consists of the following raw material components in percentage by weight: 80-82% of WC, 15-17% of Co, and 3-5% of W, Ni, Cr3C2, VC, Mo2C and TaC. The processing method for the shearing circular knife comprises the following steps: preparing knife ring raw materials, preparing knife ring blank, roughly processing the knife ring, preparing and roughly processing the knife body of the shearing circular knife, inserting the shearing circular knife and fine processing the shearing circular knife. According to the prepared shearing circular knife, use performances such as hardness, wear resistance and impact toughness resistance of a blade are further improved from material selection and a processing process, and needs, on hard plate slitting, of a user can be met; and moreover, service life of the blade is prolonged.

Description

technical field [0001] The invention belongs to the technical field of cutter processing, and more specifically relates to a method for processing a high-performance shearing circular cutter of an inlaid alloy. Background technique [0002] The sheet metal slitting machine is used for longitudinal rolling shears of ordinary metal sheets, aluminum sheets, stainless steel sheets, silicon steel sheets, etc. It mainly relies on rolling scissors (slitting and slitting blades) to roll on the sheet to complete infinitely long cutting of the sheet action. At present, rolling scissors have been widely used in aerospace, automobile manufacturing, mining machinery, hardware manufacturing, home appliances and other industries. [0003] The rolling scissors for cutting metal sheets are the most important part of slitting, which directly affects the cutting quality of metal sheets. There are extremely high demands. At present, most cutting tool manufacturers choose an alloy tool steel ...
