Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a method for forming a corrugated web for use in manufacturing heat exchanger strips, i.e. metal strips having corrugations extending laterally along the longitudinal direction. Regarding equipment.

[Conventional technology]

When manufacturing metal strips having corrugations extending laterally along their length, it is common to feed stock from a coil between forming rolls to form the corrugations. For example, typical equipment used in such manufacture is U.S. Patent No. 3.998,600, no.
No. 9, No. 4,262,568 and No. 4゜507, 9
It is described in No. 48.

[Problems to be Solved by the Invention] The object of the invention is to produce a metal strip with high productivity, to be able to change quickly in order to produce many strips at the same time, and to produce strips of different widths. It is an object of the present invention to provide an apparatus which can be rapidly changed to form a plurality of strips and which can use webs from wide coils to be cut to simultaneously form a plurality of strips.

A further object of the invention is to increase productivity without adversely affecting product quality due to long operating times, to have a packing roll mechanism that can be adjusted separately during operation, and to improve control of the concentricity of the rolls. It allows the packing roll mechanism to be adjusted separately from the preceding mechanism to change the pitch or the distance between the corrugations during operation, reduces machine downtime due to easy roll changes, and reduces the length of the web in inches. A forming or web producing mechanism is provided which drives a further mechanism to control the number of revolutions per spin and provides a selectively movable cutting mechanism laterally of the device to cut lengths of the web. That's true.

According to the invention, a plurality of webs of flat material are selectively received, one of the webs is cut to form two strips, and then the strip is shaped to form corrugations. The corrugated web forming device, which is cut to form a formed part having a predetermined length and a predetermined distance between the corrugated parts, includes at least two sets of cutting rolls that are selectively used to cut each web. a forming mechanism having at least two sets of forming rolls for forming transverse corrugations in two strips cut simultaneously from one web; a plurality of longitudinal roll pack mechanisms having at least two sets of forming rolls for control; a web control mechanism having at least two sets of rolls for accelerating and intermittently interrupting movement of the corrugated strip; and a cutting mechanism for cutting a predetermined length from the corrugated strip. In order to adjust the pitch or the distance between the corrugations, it is necessary to adjust the direction of roll of one backing mechanism relative to the other. Similarly,
One set of forming rolls for each strip must be selectively driven without driving other sets of forming rolls. Similarly, the cutting mechanism must be selectively moved towards one or the other set of strips.

Other features and advantages of the invention are detailed below with reference to the accompanying figures.

The apparatus of the invention shown in FIGS. 1 and 2 is adapted to receive webs A or B from a coil.

The selected web passes through a tension roll mechanism 30 and then reaches a cutting roll mechanism 31 where it is cut into a plurality of strips. After this the strip passes through a web forming or production roll mechanism 32 and a star wheel roll mechanism 33 which assists in the exit of the corrugated strip from the web formation or production roll mechanism 32. Next, the formed strips are successively connected to the 10th packing or density control mechanism 34 and the 20th packing or density control mechanism 35.
and through a 30th ruper, king or density control mechanism 36 which serves to control the longitudinal spacing between the corrugations on the strip.

The strip is then fed to a web control roll mechanism 37 which operates intermittently to intercept the forming strip at a cutting mechanism 38, which then moves the web and passes the next web to the cutting mechanism. accelerate to. An accumulation or hump mechanism 39 is provided between the third packing roll machine lateral 36 and the control or feed roll mechanism 37.

The cut roll cross-sections shown in FIGS. 3-7 are for selectively receiving either flat web A or flat web B and then cutting each web into two strips so as to form a corrugation. Mechanism 31 is a guide device or trunk 41.42
, each of which selectively receives webs A, B respectively and guides them between the cutting rolls. In particular, the mechanism 31 includes a lower shaft 43 and an upper shaft 4 which are mutually engaged by gears 45.46 and support a first set of cutting rolls 47.48 and a second set of cutting rolls 49.50, respectively.
It has 4. The guide devices 41 , 42 are adapted to be moved laterally by rotation of the knobs 51 , 52 which pass through the shafts 53 , 54 into the sliding devices 1 f 41 , 42 respectively and move them relative to the base 40 .

8-12, the strip forming or production roll mechanism 32 includes a plurality of sets of star wheels 55, 56 rotatably mounted on a lower shaft 57 and an upper shaft 58, respectively. As described herein, two narrow strips are sheared from web A or two wide strips are sheared from web B so as to form as the strips move along a track or tunnel T. A set of star wheels is provided on each selectably drivable shaft. Each star wheel 55
．． 56 has mutually engaged gears 59, 60 or 61.
．． 62 is provided. Lower gear 5 is moved by moving drive gear 65.
9.61, each set of gears 59.60 is selectively driven. 1st
As shown in Figure 1, a gear 65 is mounted within the cage 66, which is moved longitudinally relative to the shaft 57 by a cylinder C to move the gear 65 into engagement with either one of the gears 59, 61. It is possible.

Similarly, the gear 65 is moved vertically so that the pitch diameter of the rolls undergoes a different star wheel variation.

To accomplish this, the gear 65 is mounted on a shaft 70, in this case a sliding device 71.72, each having a pin 75.76 extending into a slot 73.74 of the fixed bracket 1-77.78. mounted on. steering wheel 8
1 to move the bracket vertically mounted on the shaft 70 and translate the brackets 71, 72 as necessary by rotating the shaft 80.

As shown in FIG. 13, the 10th packing mechanism 34 and the 20th packing mechanism 35 are the same, are rotatably attached to the frame F, and are paired to control the mutual spacing of the corrugated portions. Star wheel 94, 95 or 96,
97 includes lower and upper shafts 90.91 interengaging by gears 92.93. Web A
A set of star wheels is provided for the strips cut from the
Another star wheel is provided for the strip cut from web B. A gear 93 and rolls 94 to 97 are attached to a telescopic tube keyed to shafts 90 and 91.

For adjustment, each axle for axes 90, 91 must be moved vertically, with a vertical screw screwed into a block supporting the axle, rotated by a hand crank via a bevel gear or a motor. will be established. In particular, star wheels 94,96 are mounted on the shaft 90, which is supported on vertically movable blocks 102, 103. The screws 100, 101 connect with the blocks 102, 103 such that their translation causes the blocks 102, 103 to move vertically, which in turn causes the star wheels 94, 96 to move vertically. Screw lOO, 101
are bevel gears 104a, 105 of bevel gear devices 104, 105 rotated by shafts 106, 107, 108 by either a handle wheel 109 or a motor 110.
It is screwed into a. Similarly, the upper shaft 91 and the star wheel 95.9
6 is vertically movable by means of a device having screws, bevel gears and shafts, shown in FIG. 13 with the corresponding reference numerals and the letters raJ.

As shown in FIG. 23, each roll packing mechanism 34,
35, 36 are provided with motors 111 and differentials to momentarily drive each roll to vary the spacing and density of the corrugations per unit length of the corrugated strip.

The 30th-rupasoking mechanism 36 shown in FIG. 14 differs from the first and 20th-rupasoking mechanisms 34, 35 in that it has only an upper set of rolls 95a, 97a that engage the corrugated strip as it moves along the tunnel. . 10th - If the height of the packing mechanism is large, the 30th
- The packing mechanism can have an upper and a lower set of rolls. Accurately engage the corrugations of the strips,
In order to adjust the pitch of the corrugations of the strips relative to the adjacent strip, the rotational position of one gear 95a must be adjusted separately relative to the other gear 95b or, in the case of 97a, relative to 97b. In such a case, each gear 94a, 94b or 9(ia, 96b) of each set is rotatable relative to the other. In particular, this means that the roll 95a on the tube 91b keyed to the shaft 91a and the rolls 95b and 97a on rotatably mounted tube 91c;
This is accomplished by moving a roll 97b on a tube 91d that is keyed to the shaft 91a. gear motor 111
a is connected to the differential device 112a, and provides instantaneous rotation of the shaft 113 and gear 114° 115 to the central gear 116 on the pipe 91C. This causes the rolls 95b, 97a to instantaneously rotate relative to the respective rolls 95a, 97b. Therefore, the pitch of the corrugations of the strip associated with roll 95b or 97a varies relative to the pitch of the strip associated with roll 95a or 97b.

As with the conventional one, vertical adjustment is also required. In the roll mechanisms 34, 35, and 36, the shafts must be easily engaged and removed. Each shaft is held in place by a yoke retainer 120 that is retractable by operation of a cylinder 121 that allows each to be manually removed axially.

15-22, the web control roll mechanism 37 adjacent to the cutting mechanism 38 consists of two sets of corrugated rolls attached to a tube 127 that are keyed to a shaft 128 and are intermittently driven by a servo motor 129 via a gear 129a. 125, 12
It has 6. The rolls 125, 126 are adapted to hold the mating strips in the tunnel or track T.

As explained in the preamble regarding the density rolls, the rolls are raised and lowered as necessary. The cutting mechanism 38, as shown in FIG. 20, has a rotary cutting blade 130 pivotally mounted on an arm 131 that is raised and lowered by a cylinder 132 having a shaft 133 pivotally connected to a link 134. Link 1
One end of 34 is pivotally connected to a bracket 135 and the other end is pivotally connected to a lever 131, and upon actuation of cylinder 132, the rotary cutting blade 130 moves vertically to cut the length of the corrugated strip. is rotated by a motor 136 via pulleys 137, 138 and a bell) 139.

The bracket 135 is mounted on a platform 140 which is slidably mounted on a parallel shaft 141, so that the platform and rotating vanes can be moved into position for cutting the strip in cooperation with the rolls 125 or 126, as the case may be. Stand and rotating blade 13
0 interlocking is attached to the pedestal 140 and attached to the floor or other base 1
Piston rod 1 fixed to 45 by bracket 144
This is accomplished by a cylinder 142 with 43. The rotary vanes are thus able to move laterally to a position where they cut the strip whose motion has been interrupted by rolls 125 or 126. When the movement of the corrugated strip is interrupted by operation of the servo motor 129, the vanes 130 are actuated by the cylinder 132 to engage the strip vertically in a slot in the tunnel or trunk and remove a predetermined length from each of the two strips. Cut the corrugated strips.

The device shown in FIG. 23 has a single drive for the device excluding control rolls 125, 126, and typically has a gearbox 1.
It includes a motor 150 driving a gearbox 152, 153 in series with 51.

The gearbox 153 is connected to the drive device of each of the roll mechanisms 34, 35.degree. 36 by a transmission device. As previously mentioned, the drives of the rolls of mechanisms 34, 35 and 36 are synchronized. During operation, if necessary, mechanisms 34.35.
The relative rotational position of any one set of rolls 36 is adjustable with respect to another mechanism by momentarily actuating a differential transmission 112 in cooperation with a motor 111.

Additionally, as described above, the rolls of the third mechanism may be momentarily rotated to vary the pitch of the corrugations between strips and adjacent strips moving along the tunnel or track of the device.

This allows for the production of highly productive metal strips and the ability to quickly vary to produce multiple strips simultaneously.
A packing that can be quickly varied to produce strips of different widths and can use webs from wide coils cut to form several strips simultaneously, each independently adjustable during operation. Growl mechanism improves roll concentricity control and allows the packing roll mechanism to be adjusted independently of the preceding mechanism to change the pinch or distance between the corrugations during operation, allowing for easy roll removal and replacement. Further mechanisms can be driven intermittently to reduce downtime and control the number of web revolutions per inch, and can be selectively moved laterally to the machine to cut a predetermined length of web. It can be seen that an apparatus is provided having a cutting mechanism.
