A kind of Wave shearing process
Technical field
The present invention relates to a kind of technology of shearing sheet metal, particularly a kind of Wave shearing process.
Background technology
Punch process is the power by means of conventional or special-purpose pressing equipment, makes plate in mould, directly receive deformation force and is out of shape, thereby obtain the production technology of the product parts of definite shape, size and performance.Because punch process production efficiency is high, interchangeability is good, and is quite extensive in national economy every field range of application.Shown in accompanying drawing 2; Existing sheet metal can only carry out straight line technology to it according to pre-set dimension and shear, and the material shape of downcutting can only be rectangle or square through after flattening; If the punching press round piece is even then the intersection discharge still has a lot of clout wastes.
Summary of the invention
The purpose of this invention is to provide a kind of Wave shearing process, can be on sheet metal fully utilize the clout between discharge during the punching press round piece.
The technical scheme that the present invention taked is: a kind of Wave shearing process, be used for the sheet metal that the shearing of sheet metal is processed, sheared after processing is used for the capable round piece of punching press n, and wherein n is the positive integer more than or equal to 3, this technology comprises the steps:
A, with sheet metal volume leveling;
B, described sheet metal is sheared along width, the shear line after the shearing is concaveconvex shape, and described shear line is made up of with the transition wire that the n-1 section is connected adjacent edge line n section edge line; Wherein, One section edge line edge line capable with respect to m+1 and the capable place of m-1 at the capable place of m outwards protrudes or caves inward; And connect m-1 capable with the capable edge line of m one section transition wire, be connected that m is capable to constitute regular hexagon half with one section transition wire of the capable edge line of m+1 and these three lines of one section edge line at the capable place of m; The orthohexagonal size at this half regular hexagon place just and the round piece of following process circumscribed orthohexagonal measure-alike, above-mentioned m is more than or equal to 2 positive integers smaller or equal to n-1.
Utilize Wave shearing process of the present invention; Can when the punching press round piece, fully utilize the clout between discharge before; Only need utilize original shearing equipment, through after improvement and incorporating new technology and equipment component renewal, need not to increase the effect that has realized economical with materials under the situation of operation; Improved stock utilization greatly, when this Wave shearing process especially is fit to the bigger round piece of ram ratio to the shearing of sheet metal.
Description of drawings
Accompanying drawing 1 is the sketch map of Wave shearing process of the present invention (dotted portion is the situation of arranging of punching press round piece);
Accompanying drawing 2 is the sketch map of existing Wave shearing process (dotted portion is the situation of arranging of punching press round piece).
Wherein: 1, sheet metal; 2, round piece; 3, shear line; 31, edge line; 32, transition wire.
The specific embodiment
Come further to set forth Wave shearing process of the present invention below in conjunction with accompanying drawing.
Shown in accompanying drawing 1, a kind of Wave shearing process is used for the sheet metal 1 that the shearing of sheet metal 1 is processed, sheared after processing is used for the capable round piece 2 of punching press n, and n is 7 in the present embodiment, and this technology comprises the steps:
A, with sheet metal volume leveling;
B, described sheet metal 1 is sheared along width, the shear line 3 after the shearing is concaveconvex shape, and described shear line 3 is made up of 7 sections edge lines 31 are connected adjacent edge line 31 with 6 sections transition wire 32; Wherein, One section edge line, 31 edge lines 31 capable with respect to m+1 and the capable place of m-1 at the capable place of m outwards protrude or cave inward; And connect m-1 capable with the capable edge line 31 of m one section transition wire 32, be connected that m is capable to constitute regular hexagon half with one section transition wire 32 of the capable edge line 31 of m+1 and one section edge line, 31 these three lines at the capable place of m; The orthohexagonal size at this half regular hexagon place just and the round piece 2 of following process circumscribed orthohexagonal measure-alike, above-mentioned m is smaller or equal to 6 positive integer more than or equal to 2.
The present invention is according to the concave-convex design theory, when the punching press round piece before discharge between clout fully utilize, improved stock utilization greatly, when this Wave shearing process especially is fit to the bigger round piece of ram ratio to the shearing of sheet metal.
