Abstract
A method for forming the blade of facsimile apparatus includes such steps as cutting a plate by proper length, fixing it to the die of punch machine in such manner that one plate edge to become cutting edge is extended out of the die and there is an angle between the plate and the punch direction of punch machine, and punching to remove part of plate and form a cutting edge. Its advantages are high productivity and high precision.
Description
[technical field]
The present invention relates to a kind of forming method of facsimile edge, be meant a kind of method for shaping facsimile edge especially.
[background technology]
The blade of the usefulness of cutting a sheet of paper is equipped with in regular meeting in the facsimile machine, and this class blade generally all is long strip type, because the required precision of facsimile machine to cutting a sheet of paper, and the requirement of the flatness tolerance at blade two ends is tighter.At present, facsimile edge processing method commonly used is after sheet metal carries out machining, process blade by attrition process again, yet, the difficult control of this traditional processing mode, the flatness tolerance of the blade that not only processes, the product percent of pass that processes can't be protected, and working (machining) efficiency is very low, and manufacturing cost is corresponding higher.
[summary of the invention]
Technical problem to be solved by this invention is: a kind of method for shaping facsimile edge is provided, and it can process qualified blade by mass apace, and can guarantee the flatness of blade.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of method for shaping facsimile edge is provided, and it comprises the steps: a, cuts out the sheet material of suitable length; B, this sheet material is fixed on the mould of punch press, the edge that sheet material need be molded into blade stretches out outside mould, this mould locates to establish a folding face below this edge of backup plate material, and fixed plate makes between the pressing direction of itself and drift angled, makes the stamping-out face enter sheet material and pass from the side of sheet material from the upper surface of sheet material is oblique; C, by the punch ram moulding, remove part sheet material along stamping-out face stamping-out, and in the stamping-out action later stage, the marginal portion that is forced sheet material by drift is to the folding dough model distortion of mould and be close on the folding face and form blade part.
The invention has the beneficial effects as follows: by cooperating with mould and come shaping blades by impact style, can be one time punching molded go out qualified blade, its production efficiency improves greatly, and can realize producing in enormous quantities; Simultaneously, its flatness can be ensured that flatness can be controlled between 0.02～0.03mm by high-precision mould, drift.
The present invention is described in further detail below in conjunction with accompanying drawing.
[description of drawings]
Fig. 1 is that the sheet material of method for shaping facsimile edge of the present invention is fixed in the stamping-out schematic diagram on the mould.
Fig. 2 is the side-looking enlarged drawing of blade part of the blade of method for shaping facsimile edge of the present invention institute moulding.
[specific embodiment]
The invention provides a kind of method for shaping facsimile edge.
As shown in Figures 1 and 2, facsimile edge is that sheet material processes, and it comprises a knife plate 21 and a blade part 22, wherein this blade part 22 from a skew back of this knife plate 21 to stretching out.
Method for shaping facsimile edge of the present invention comprises the steps:
A, cut out the sheet material 1 of suitable length;
B, this sheet material is fixed on the mould 31,32 of punch press, the edge that sheet material 1 need be molded into blade stretches out outside mould, this mould 32 locates to establish a folding face 321 below backup plate material 1 this edge, and fixed plate 1 makes between the pressing direction (the direction A among Fig. 1) of itself and drift (scheming not shown) angled, make stamping-out face (representing with double dot dash line among Fig. 1) enter sheet material 1 and pass from the upper surface of sheet material is oblique, as shown in Figure 1 from the side of sheet material 1;
C, by the punch ram moulding, remove part sheet material along stamping-out face stamping-out, and in the stamping-out action later stage, the marginal portion that is forced sheet material 1 by drift is to folding face 321 plastic deformations of mould 32 and be close on the folding face 321 and form blade part, after the moulding, the length of this blade part promptly is the length of sheet material, is about 0.5mm and the thickness H on its top is about 0.15mm, width L, as shown in Figure 2.
By cooperating with mould and come shaping blades by impact style, can be one time punching molded go out qualified blade, its production efficiency improves greatly, and can realize producing in enormous quantities; Simultaneously, its flatness can be ensured that flatness can be controlled between 0.02～0.03mm by high-precision mould, drift.
Claims (2)
1, a kind of method for shaping facsimile edge, it comprises the steps:
A, cut out the sheet material of suitable length;
B, this sheet material is fixed on the mould of punch press, the edge that sheet material need be molded into blade stretches out outside mould, this mould locates to establish a folding face below this edge of backup plate material, and fixed plate makes between the pressing direction of itself and drift angled, makes the stamping-out face enter sheet material and pass from the side of sheet material from the upper surface of sheet material is oblique;
C, by the punch ram moulding, remove part sheet material along stamping-out face stamping-out, and in the stamping-out action later stage, the marginal portion that is forced sheet material by drift is to the folding dough model distortion of mould and be close on the folding face and form blade part.
2, method for shaping facsimile edge as claimed in claim 1 is characterized in that: at an angle, after the punch forming, the certain angle that is become between blade part and the knife plate promptly equals the angle between this folding face and the sheet material between this folding face and the sheet material.
