Description
Technical field:
The present invention relates to the new method of a kind of preferred in a row cutting and the combination processing that is shaped.
The invention still further relates to a kind of rotary cutter of realizing this method.
Background technology
In many commercial Application, it is known adopting cutting and shaping combination processing.These otch are a spot of or opposite, and the closeness of its otch can be very high, for example for the acoustics drip molding or be used for the drip molding of cable pipe.
One of technology that is used to make the dividing plate with acoustical absorbance properties is to pass through the Surface Machining of the form metal that adopted, that is: make its surface have a plurality of holes and realize.Present method or employing have the perforation drip molding of minor diameter circular hole usually, perhaps adopt to form other drip molding of wearing mouth thereon.These wear a mouthful otch that is the part, and it is also normally rectangular that otch leaves the smear metal that is connected on the sheet metal.The characteristics of above-mentioned drip molding are that the otch intensive is very high, and every square metre has thousands of holes.
Shaping is a kind of of the multiple manufacturing cable plumber skill that adopts.Like this, also the cutting and the processing that is shaped must be grouped together.The quantity of its otch is lacked than its quantity of acoustics drip molding, but still a lot.
The column of other products such as metal shelf is made by the drip molding with otch usually.In a kind of example in back, the otch number is less.
In order to make otch quantity drip molding more or less, the method for employing is different.In fact, main two types of its method can be to make by punch press or by rotary cutter to distinguish according to its otch.
Can make at shaping first being processed disengaging shaped wire by the otch that punch press forms, or by being installed in the punch press in the shaped wire or after the processing that is shaped, making.
Before shaped wire and break away from the shaping line when forming otch, additional treatments technology is a lot of and increased expense.When punch press was arranged in the shaped wire, machining was starkly lower than forming speed.Finally, the otch of making after being shaped causes because the constraint of being careful that the position of otch on the product of shaping limited to and being brought by cutting tool, and this also has adverse influence for productivity ratio.
Rotary cutter is used for punch press selectively, and its process velocity can be complementary with the speed of shaped wire.
For example, such cutter is described in following patent (patent application): GB-A-1044313, and GB-A-1 123 536, and US-A-1 581 236, US-A-1 333 704, US-A-3 828 636, and US-A-3205 744, and US-A-3 709 077, US-A-3 438 835, US-A-3 274 873, and US-A-3 066542, and US-A-5 040 397.System described in these different documents does not all provide a kind of technical scheme that is fit to address the above problem.They or only provide machining and do not worn mouthful processing, perhaps its very complexity and expense height when forming many wear mouthful.Subject matter is to produce a large amount of scrap of discharging owing to wear a mouthful meeting.
In this case, the selectable mouthful otch by a part of wearing constitutes, and smear metal still is connected on the sheet metal, to solve the problem of its discharge.This processing can be realized by rotary cutter, but exist other problem.Following cutter is a diskware, the cutting of high-quality only obtains in the direction parallel with the sheet metal motion, its vertical edges is quite uneven, this may cause and gets rusty, and, owing on sheet metal, keep smear metal, can prevent and the formation of wearing mouth of forming rolls contact area that this has obviously reduced the actual apparent surface that can form the drip molding of wearing mouth.In addition, because the influence of rotary cutter technology, smear metal approaches 45 degree with respect to the angle on sheet metal plane even to 90 degree, this has obviously reduced the profile hole.Be starkly lower than the performance of its drip molding that forms by the system of boring by the performance of wearing the acoustics drip molding that vocal imitation skill forms.
US-A-4 766 707 has described a kind of machinery, comprises the first pair of rotating cylinder that is used to the system of boring, then by second pair of rotating cylinder smear metal bonding jumper.In this mechanical back shaping or bar folder are installed according to purpose, to make the intermediate plate of roofing board.Its first pair of cutter forms taper embossing or hole, is used to accept fixture, as the nail part.Second pair of cutter forms transverse groove on each vertical limit of bar, two adjacent part is lax the connection at the middle part, to help the separation of intermediate plate.The speed of two types of processing is obviously different.
US-A-1 931 468 has described similar installation, and the motion of pair of rollers is wherein regulated by gear train assembly.Brill system in the processing realizes having the passage that is used to discharge smear metal in one of them rotary cutter by a pair of rotary cutter once or twice.

The specific embodiment
The objective of the invention is to make rectangular slits or wear mouth, guarantee high-quality cutting and when cutting, discharge smear metal easily or when wearing mouthful, guarantee high-quality otch and kink by processing being divided into two stages.
Basic principle adopts two pairs of continuous rotary cutters as shown in Figure 1.When cutting hole, its principle is that machining is divided into two stages.On the one hand, the first pair of rotating knife forms cross sections with respect to the traffic direction of sheet metal, and on the other hand, second pair of rotating knife forms longitudinal cut, guarantees that smear metal discharges easily.When wearing shape of the mouth as one speaks cutting, first tool setting is for example cut on three limits.Then, second tool setting smear metal of turning back, thus obtain tangible profile hole with respect to prior art.Yet, in immediate prior art US-A-4 766 707, the continuous processing that realizes by rotary cutter (embossing or the system of boring are sheared) be finish in different zones and its purpose different fully.
Fig. 1 shows total figure of system.Comprise being installed in cutter 1 and 2 the first pair rotary cutter otch that on sheet metal form part of axle on 6 and 6 ' respectively, do not arrange smear metal.By comprise be installed in respectively the axle 6 " and 6 on cutter 3 and second pair of rotary cutter of 4 otch is rebuild.These are bearing on the bearing of being located at all terminations, and this termination (not shown) is similar to the termination of forming head.The direction of rotation of each cutter is by B, B ', B ", B represents.Sheet metal with shown in direction A operation, its speed equals the peripheral speed that formed by cutter 1,2,3,4.
Fig. 2 and 3 shows the preferred embodiment of rotary cutter 1 and 2.Particularly Fig. 2 shows circular blade member 11 and 21 up and down, and it makes the notch indentation 7 (referring to Fig. 5) vertical with sheet metal 5 traffic directions on metallic plate.As described in Figure 3, the element 1 of fixing a cutting tool comprises a plurality of typical circular cutter tooth spares 11 and distance piece 12.These blade members are installed on the axle 6, and locate and be fixed on this axle in direction of rotation by element such as pin.These parts also axially are being fixed, and guarantee accurate location.Equally, bottom tool spare 2 comprises a plurality of 21, and their facing pieces 11 are also separated by part 22, when cutting notch 7 as horizontal cutter.Part 21 and 22 rotational fixation and in axial location are the same with the situation of cutter 1.Part 11,12,21 and 22 preferably by making through heat treated tool steel, is the standard cutting tool.
The advantage of processing the method for its rotary cutter is and since part for example part 11 or 12 can make by a plurality of discoid heat treatment tool steel being carried out the line cutting, improved the economy of making cutter.
Cutter 1 and 2 guarantees by the backstop on the axle that is installed in the bearing horizontal level that is in the supporting head in axial location.Circular cutter 11 and 21 belt tooth 111,111 ', 211,211 ' relative radial location are by at least one gear-box assurance with axle 6 and 6 ' synchronous operation.Preferred gear can effectively guarantee the accurate location that is suitable for cutting in groups.At least one of axle 6 or 6 ' makes the peripheral speed of cutter equal the speed of service A of sheet metal by motor-driven.
Fig. 4 shows the belt tooth 111 or 111 ' and the annular tooth 211 of circular cutter 21 or 211 ' two embodiment of circular cutter 11.
After passing through a pair of rotary cutter, its sheet metal forms notch 7 as shown in Figure 5.
Fig. 6 and 7 shows the common bite 31 and 41 that carries out second working angles.Have tooth 311 on the circumference of its circular bite 31, the length of its circular arc equals the distance between the two continuous notches 7 in machining tolerance.
Its complete circle is fixed a cutting tool and 3 is comprised a plurality of common bite 31 that is separated by distance piece 32.The locate modes axial and circumferential registration and cutter 1 and 2 of its bite 31 are similar.In addition, axle 6 " with axle 6 synchronous operations, guarantee that notch 7 and bite 311 accurately locate.This synchronous operation for example realizes by gear train.
Its cutter 4 comprises a plurality of common cutting discs 41 and distance piece 42 (Fig. 7).Their axial location is identical with cutter 1 and 2, only at the relative positioning that axially guarantees its cutter 3 and 4.In machining tolerance blade member 11,21 and 31 and the width of distance piece 42 equate.
For smear metal is easy to discharge between dish 41, a comb can be set, its tooth is arranged between dish 41 teeth, discharges the smear metal that gets lodged between the cutting disc 41, then for example by the horizontal dispatch smear metal of conveyer belt.
Fig. 8 shows the optimum position of cutting.In fact, its method can accurately provide the accurate amount of cutting force, particularly by cutter 1 and 2 cutting notches the time.In order to reduce its cutting force, can offset cuts, as shown in Figure 8.
Fig. 9 shows the parameter of being considered: horizontal spacing Ptr, longitudinal pitch Plg, cross cutting DecTr and straight-cut DecLg.Stock removal rate is cutting face (DecTr * DecLg) and the spacing face (ratio of Plg * Ptr).This parameter is determined for example sheet material acoustic mass.Select the value of parameter shift decision number X enough big, determine its displacement, to reduce to act on the power on the axle.In fact, when big more particularly its X of value of parameter shift decision number X was not integer, produced simultaneously otch was few more.
Another important parameter is the ratio between non-cutting longitudinal length Plg-Declg and the displacement interval Plg/X.If its ratio is integer, the rectangular opening of cutting is corresponding with the hole of the cutting second time of arranging number with the conversion that equals described ratio for the first time.In this case, the cutting hole count of Xing Chenging is many relatively simultaneously, but by producing cutting in pairs, the radial load that acts on the bite compensates one another, and has reduced to act on the moment of axle.If selected cutting parameter makes that its ratio (Plg-Declg)/(Plg/X) is not integer, the cutting hole count of Xing Chenging reduces simultaneously, and bending force reduces, but the moment that acts on the axle increases.
Table 1 shows and is suitable for the parameter selection that its ratio is not integer, and Figure 10 shows the specific embodiment of cutting pattern.
The present invention also is suitable for cutting through hole, promptly need not get rid of material.
The operation principle of cutter is identical.Form the U-shaped otch through first pair of cutter 1 and 2, as 7 ' (vertically) and 7 among Figure 11 " shown in (laterally).Adopt the profile of tooth 111 of universal cutter 11.Form kink 8 through second pair of cutter, unlike before, cut.Adopt the tooth 311 of universal cutter 31: on bending edge, be round shape and also contact with its bending edge all the time.Figure 12 shows this view of wearing mouthful vertical and horizontal.
For different application, the diameter of its cutter is determined by the contact condition of the stability of material that depends on shaft size and circular cutter and sheet metal.Therefore, its cutter 1 and 2 radius preferably are equal to or greater than 100 times of sheet metal thickness.For wearing mouth, its selected cutter 3 can be different with 4 radius, and for example the radius of cutter 4 is obviously greater than the radius of cutter 3, guarantees when the bending operation supporting metal sheets material well.
In a special embodiment, cut and wear a mouthful operation and can in a machinery, finish along conveyer belt, its conveyer belt is parallel with the traffic direction of sheet metal, wears mouth and is positioned at and the discontiguous zone of forming tool.
