Content of the present invention
The purpose of this invention is to provide a kind of method and mould that forms waveform bar-stock, use this method and mould easily metal tape to be cut into to satisfy dislocation to cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing the waveform bar-stock of requirement.
The present invention adopts earlier the metal tape upper punch fabrication hole after uncoiling, smoothing with the wavy line segmentation for achieving the above object, and then with wavy line a section the method cut off, metal tape is cut into a rule waveform bar-stock.
This method may further comprise the steps:
After metal coil tape uncoiling, the smoothing, elder generation is divided into wavy line towards fabrication hole sectional with perforating die, and then with the waveform shearing edge sectional wavy line is cut off.Because every section the length of separating is identical with the length of waveform shearing edge, so segmentation so circularly, shear and just metal tape to be cut into a rule waveform bar-stock.
Purpose towards the fabrication hole segmentation is in the method: 1. wavy line is that a section ground shearing is opened, because the horizontal and vertical position error of metal tape, may cause that wavy line is not thoroughly cut when connecing cutter, even behind fabrication hole, have a position error also a section wavy line thoroughly can be cut.2. when last cutter of a section shear-wave line and back one cutter connect cutter, owing to making, position error shears scrap (bridge) seldom, will influence the service life of shearing knife edge like this, behind fabrication hole,, influence the service life of blade when connecing cutter with regard to there not being the little problem of scrap (bridge) because fabrication hole separates a section wavy line.
Waveform described in the top method has: two kinds of circular arc waveform (Fig. 1) and broken line waveforms (Fig. 2), waveform configuration can satisfy dislocation and cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing requirement, can select as required in practice.
Described fabrication hole is shaped as circular, square, triangle etc., and its position otherwise the requirement that the influence dislocation is cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing in the method.The length of punching segmentation can be a wave period, also can be a plurality of wave periods, can increase or shorten according to actual conditions.
Can realize the continuous production of waveform bar-stock when the metal tape rolling provides in the method and more help economical with materials.
Described in the method metal tape is meant steel band, tinplate band, ferrosilicon band, aluminium strip, stainless steel band etc.
The waveform bar-stock of shearing out can be rolled into use in the method, also available follow-up equipment cuts into Zhang Ping's plate and uses, and can select as required in practice.
Second purpose of the present invention provides a kind of mould that forms waveform bar-stock, metal tape after uncoiling, the smoothing, by using the first station punching segmentation of two station progressive dies, the second station wavy line is sheared, just can expediently metal tape be cut into waveform bar-stock, in this punching course, metal tape send the length that step pitch equals the punching segmentation to, also equal the length of waveform cutting edge.In this punching course metal tape intermittent delivery mechanism to send step pitch to correct, and have metal tape to carry guiding and positioner.
The 3rd purpose of the present invention be by implement said method and (or) use above-mentioned mould, metal tape can be cut into and satisfy dislocation and cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing the waveform bar-stock of requirement.
After employing cuts into the method and mould of waveform bar-stock with metal tape, bucket end bung to the tubbing industry is produced, the jar end cover of system jar industry, the can body production of seamless tin, the stator of electric manufacturing, rotor production, the pots and pans production of irommongery etc. all can change former use rectangle billot into the use waveform bar-stock, like this can material saving about 6～12%.
