Abstract
The process for stamping of a kind of limit stamping-out spring song can be finished the stamping-out and the bending of the stamping parts with curvature simultaneously with the means of single operation in a punching stroke.It is 15 ° to 85 ° inclined-plane work cutting edge that its punch has inclination alpha, and decide on the quantity and the position of the bending curvature of stamping parts what and position of its cutting edge.This punch manufactures and designs simply, and die trial repairs a die easily, production efficiency height, bool section flawless.
Description
The invention belongs to mechanical engineering, can be used as the process for stamping of punching press industry production bool.
Current punch process bool mainly contains following three kinds of processes: (1) single die, and promptly first with a secondary blanking die blanking, back with a minor bend mould or the bending of many minor bends mould.(2) progressive die, promptly at the last work step stamping-out of this mould, the work step bending of back, or stamping-out and bending hocket.(3) multiple station die promptly after last station stamping-out, by manipulator or pick mechanism automatically, is delivered to following station bending.These methods, when overcoming bending springback, die trial repairs a die pretty troublesome, the process unit complexity, production efficiency is low, occurs bending crack easily.
The objective of the invention is to means, in a punching stroke, finish the stamping-out and the bending of stamping parts simultaneously with curvature with single operation.The stamping-out process stops, and BENDING PROCESS also finishes simultaneously.
The process for stamping of limit stamping-out spring song is embodied in unusual that punch designs.With existing punch relatively, it is all the same in the selecting for use of material, manufacturing and heat treatment, the difference of the two only is the geometry difference.The punch that this method is used has inclination alpha and is 15 ° to 85 ° inclined-plane work cutting edge.Decide according to needing crooked quantity and position thereof on the bool what and position of punch inclined-plane work cutting edge.Condition such as the width of the thickness of the amount of curvature of neglecting bool greatly of inclination alpha, the performance of sheet material, sheet material, blanking part and deciding.
In the existing stamping press, have because the restriction of the intrinsic capacity of forcing press, and punch is designed to have the inclined-plane cutting edge at inclination angle, so as to reducing stamping press, thereby the load of the machine that eases off the pressure.But in order to guarantee the flatness of blanking part, inclination alpha is all below 8 °, and normal palpus symmetric arrangement.Utilize this method production, lateral pressure appears in the stamping-out process, causes the width of bool to produce compression, causes the diastrophic inboard of stamping parts and the outside, all produces compression strain at width.The ess-strain of this bool width with its radially with the tangential deformation mechanics figure that ess-strain constituted, help flexural deformation, its bool section crackle can not occur.Utilize this method, can overcome diastrophic elasticity at an easy rate and recover phenomenon.As long as the size of reconditioning punch cutting edge inclination alpha just can reach the purpose that changes the bool radius of curvature.Simultaneously, the mould simplicity of design, easy to manufacture, the production efficiency height.
Accompanying drawing 1 is the bent work of a circular arc bool limit stamping-out spring schematic diagram.
Accompanying drawing 2 is six kinds of stamping parts embodiment of six kinds of bent punch of limit stamping-out spring and corresponding processing thereof.
Claims (2)
1, the process for stamping of a kind of limit stamping-out spring song, its principal character are that to have inclination alpha be 15 ° to 85 ° inclined-plane work cutting edge to punch.
2, the process for stamping of a kind of limit according to claim 1 stamping-out spring song, its principal character are that decide according to the quantity of bending on the bool and position thereof what and position of punch inclined-plane work cutting edge.
