Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
Consult Fig. 2, 3, a preferred embodiment of the die-cut method for making of the present invention can punch out on a metal plate and belt 3 at least two rows along a width 32 between left and right every odd number row chain blade unit 2, and the even numbers row chain blade unit 2 ' that at least one row is also connected between described odd number row chain blade unit 2, often arrange odd number row and even numbers row chain blade unit 2, 2 ' all has several chain sheet 20 connected before and after a length direction 31, that is, this metal plate and belt 3 is along this length direction 31 intermittent feeding, described odd number row and even numbers row chain blade unit 2, 2 ' is extend along this length direction 31, described odd number row and even numbers row chain blade unit 2, 2 ' is connected side by side along this width about 32 simultaneously, this width 32 is perpendicular to this length direction 31.And the quantity of described odd number row and even numbers row chain blade unit 2,2 ' is width according to this metal plate and belt 3 and determine, when enforcement, not with being limited disclosed by this preferred embodiment.
The present embodiment each chain sheet 20 has two and arranges before and after the spaced and parallel straight flange 21, two of this width about 32 and the perforation 23 being connected to 22, two, end limit between described straight flange 21 time interval respectively, and a trade mark 24 be positioned between described perforation 23.This die-cut method for making comprises: the punching step of the shaping trade mark step of the trade mark 24 of a described chain sheet 20 of formation, the perforation 23 of a described chain sheet 20 of formation, and a blanking punching step cutting out the appearance profile of described chain sheet 20, abovementioned steps can separately be carried out, also a mould can be utilized synchronously to carry out, and this preferred embodiment utilizes a mould interval synchronously to carry out previous process steps on this metal plate and belt 3.
This shaping trade mark step of the present embodiment, mainly utilizes mould to become the trade mark 24 of described chain sheet 20 in this metal plate and belt 3 upper punch swaging.And this punching step is the perforation 23 punching out described chain sheet 20 on this metal plate and belt 3, after die-cut, the perforation 23 of each chain sheet 20 is along this length direction 31 time interval.
This blanking punching step of the present embodiment synchronously can cut out wherein several appearance profile of described chain sheet 20, and in the process that each circulation cuts in this blanking punching step, cut out one of them chain sheet 20 of each odd number row chain blade unit 2 and even numbers row chain blade unit 2 ' respectively, specifically, die cutting die is often once die-cut in the present embodiment, three chain sheets 20 ' as shown in Figure 2 can be punched out, wherein, the chain sheet 20 ' of described odd number row chain blade unit 2 is left and right alignment, and the chain sheet 20 ' of this even numbers row chain blade unit 2 ' connects not with the chain sheet 20 ' of described odd number row chain blade unit 2, what is called also connects, namely connect side by side.Simultaneously along this width 32, the chain sheet 20 of described odd number row chain blade unit 2 aligns, and the chain sheet 20 of this even numbers row chain blade unit 2 ' and the chain sheet 20 of described odd number row chain blade unit 2 stagger before and after being, the length staggered is 1/2nd of the length of described chain sheet 20.That is, the present embodiment is in order to ensure the integrality of described chain sheet 20 appearance profile after cutting, and the relation of arrangement of molds, circulates in the process that cuts at each, be make left and right adjacent chain sheet 20 before and after to stagger the length of half chain sheet 20.Before die cutting die carries out die-cut three chain sheets 20 ' as shown in Figure 2 at every turn, three chain sheets 20 of its front end " state be cropped go out appearance profile, only remaining front and back end is connected with the chain sheet 20 arranged together.
Specifically, this blanking punching step of the present embodiment is in the process that cuts of at every turn circulating, synchronously and respectively can cut out one of them of the described chain sheet 20 of each odd number row chain blade unit 2, cut out one of them of the described chain sheet 20 of this even numbers row chain blade unit 2 ', the length of half chain sheet 20 and this even numbers row chain blade unit 2 ' and the left and right adjacent chain sheet 20 of odd number row chain blade unit 2 stagger before and after on cropped relative position being simultaneously.Thus, straight flange 21 on the odd number row chain blade unit 2 that not only left and right is adjacent and the chain sheet 20 of even numbers row chain blade unit 2 ' can not stay the overlap in gap, in the process cutting every a slice chain sheet 20, local form's profile of every sheet chain sheet 20 all can be connected with this metal plate and belt 3, therefore the present embodiment when not needing reserved gap, left and right, can cut out the chain sheet 20 that appearance profile is complete.By that analogy, just by the blanking punching step that cut of circulating, this metal plate and belt 3 can punch out described chain sheet 20, after cutting, the present embodiment only can produce a similar leg-of-mutton waste material 33 between the adjacent described chain sheet 20 in left and right and front and back.
That is, the present embodiment is in the process repeating shaping trade mark step, punching step and blanking punching step, chain sheet 20 on each odd number row chain blade unit 2 and even numbers row chain blade unit 2 ' is from beginning to end, namely, the end limit 22 of the chain sheet 20 of described odd number row and even numbers row chain blade unit 2,2 ' is all from beginning to end along this length direction 31, therefore, the waste material between described odd number row and even numbers row chain blade unit 2,2 ' can be reduced to minimum by the present embodiment.
On the other hand, along this width 32 between left and right every the chain sheet 20 of odd number row chain blade unit 2 and the chain sheet 20 of this even numbers row chain blade unit 2 ', its straight flange 21 also can stagger and partly overlap in front and back, therefore the present embodiment after fabrication, waste material is not had to produce yet along between the odd number row and even numbers row chain blade unit 2,2 ' of this width 32 left-right situs.Previous designs compares with the patent of invention of Fig. 1, really has the effect reducing waste material further.Minimizing due to waste material is equal to the stock utilization improving this metal plate and belt 3, therefore the present invention also has the effect of saving material cost.
