Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] see Figure 1~3 , a forming roll for kitchen knives and its use method, which is composed of a roll body 1 and a roll connecting shaft 3, and is characterized in that: the roll body 1 is circumferentially distributed with a special-shaped pass 2 with a V-shaped deep groove; One side of the V-shaped deep groove of special-shaped pass 2 is vertically perpendicular to the roller surface, and the other side gradually transitions into a horizontal shallow groove through the arc surface. The depth of the V-shaped deep groove of special-shaped pass 2 is H=510mm, and the bottom corner of the V-shaped deep groove has a circular arc transition, and the radius of the transition arc is r=2-5mm; the depth of the shallow groove is h=0.5-2mm. The transition arc radius R of the deep groove and the shallow groove of special-shaped pass type 2 is 30-40mm.

Abstract

The invention discloses a forming roll for kitchen knives and a method for using it. It consists of two parts: a roll body and a roll connecting shaft. The surface gradually transitions into a special-shaped pass with horizontal shallow grooves. The invention can make the plate blank used for special-shaped kitchen utensils go through 2-3 rollings to form a style with a thick back and a thin blade; meanwhile, it can meet the requirements of continuous rolling and mass production.

Description

technical field [0001] The invention relates to a material forming roll and a using method thereof, in particular to a forming roll and a using method for producing special-shaped bone chopping knives, kitchen knives and other kitchen knives. Background technique [0002] For kitchen knives and bone chopping knives, in order to increase the impact force during use, the back of the knife is often thickened to increase the weight. However, in order to prevent the knife from being too heavy, the body of the knife should be light and thin, thus forming a knife style with a thick back and a thin blade. The unique inventions and creations of the working people in our country have a long history and cultural origin of thousands of years. This traditional style of kitchen knives is all forged by hand. At present, relying on manual forging alone obviously cannot meet the mass production requirements of such special-shaped kitchen knives. [0003] Therefore, in order to reduce labor...
