Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a device for correcting the rows of ears of a battery plate group.

(Prior art) K-p is applied to the ear row of the electrode plate group for a storage battery by the Caston method.
t = Hll -/Mo474- IMP 1 type'I
Jw6 d? -h'L ΔΔ The length of the ear row of the Wff group may be smaller than the length of the four strap-forming parts that open on the upper surface of the strap-forming layer mold. In this case, when the ear row of the electrode plate group is inserted into the strap recess, one or both of the outermost ears of the ear row cannot be accommodated in the recess, and the intended It is not possible to cast the strap into one piece on the ear row using the Caston method. Therefore, before applying the caston method to the electrode plate group, it is necessary to correct the tab row of the electrode plate group in advance so that it can be inserted into the recess. A correction method and device were used in which the ear row was press-fitted between a predetermined guide width with tapered ends, and the tapers at both ends caused the outermost ears of the ear row to bend inward. . In this way, the electrode plate group having the corrected lug row can be inserted into the strap forming recess of the casting, and the Caston method can be performed, since the ears at both ends of the lug row are bent inward. \Become.

(Problems to be Solved by the Invention) Even if the above-mentioned conventional method and device for correcting ear alignment using a plate group are used,
The ear rows are corrected by gradually pressing inward from the outside of the ear fittings at both ends by the tapered surfaces, so when the inward pressing force is released, the relatively large back cushion returns the ear rows to the outside and corrects them. Even if the ear row is imperfect, there is a problem in that even after correction, the ear row cannot be inserted into a predetermined recess for forming the strap.

(Means for Solving the Problems) The present invention provides a method for correcting the ear rows of a storage battery plate group, which eliminates the inconveniences of the above-mentioned conventional plate group reissue correction method and device and provides complete correction. In this system, in conjunction with the operation of the piston rod of the piston cylinder, the opposing correction pressurizing member collides with both outermost ears of the ear row of the electrode plate group, thereby instantly applying pressure inwardly. It is characterized by being compressed and bent.

The present invention also provides an entire straightening device for carrying out the straightening method, in which the cylinder tube of the piston cylinder and the piston rod are each provided with a flange, and each flange is provided with at least one flange.
The main long rod is configured into a pair of cooperating rods extending parallel to each other along the length direction of the piston cylinder, and at least one protrusion is provided on each of the pair of long rods in the front and back. In addition, the rows of ears of the electrode plate group are arranged at intervals that allow insertion when the piston rod of the piston cylinder is not in operation, and in conjunction with the operation of the piston rod, the front and rear pairs of these It is assumed that the protrusion collides with the frontmost ear and the rearmost ear of the row of ears inserted within the interval, causing them to instantly bend inward.

(Example) An example of the orthodontic device of the present invention will be described in detail with reference to the accompanying drawings.

In the drawing, (1) shows a piston cylinder supported horizontally on a support stand (2). A plate-shaped flange f3) +31 is fixed to the tip of the cylinder tube (1a) of the piston cylinder (1) and the tip of the piston rod (1'b), respectively. When the piston rod (1'b) is in the extended state, the front flange (3) and the rear flange (3) touch each other as shown in Figures 1 and 2A. Although they are located relatively far apart, during the contraction operation, they are positioned close to each other as shown in Figure 2B. The upright walls (2&) of the support stand (2) are located on the left and right sides of the piston rod (1'b) passing through the center thereof, and the guide sliding rod (4) (4) e penetrates at both side wall portions. Each sliding rod (4) is supported by front and rear tsubari (31+) at both front and rear ends.
31 tl- is penetrated, and at both ends thereof, an annular stopper +51 (51) made of a cushioning material such as elastic rubber is fixed to each outer end of the protruding flange f3> +3 The moving protrusion 31 (31 is prevented from moving any further outward). Also, in the middle of each layer moving rod (4), in contact with the front and rear surfaces of the upright wall (2a), there are two Your annular stopper +51 [51'!- Fix it,
Aim to prevent the Tsutsuba f31 +3) moving in the direction of approaching each other from getting any closer. The front and rear protrusions f31 +31 extend beyond the sides of the support base (2) at each 1 (1j [l) to -M-I/-19-hp Gego? Hatsuha6RI÷Through this, to each Tsutsuba (3),
Two upper and lower parallel long rods (61 (61 and (7) (71) are fully extended along the length direction of the piston cylinder (I), and each upper rod extending from 31 (31)
6) (7) is constructed as a pair of cooperating rods, which will be described later, that are close to each other and extend parallel to each other, and is similarly constructed as a main rod. The spacing is approximately equal to the spacing between the rows of cathode ears that protrude from the parallel upper and lower rods and the rows of anode ears that protrude upward from the other side. The arrangement of these four long rods is as follows: two U-shaped rods are prepared in advance, and a vertical connecting rod (8 ) is conveniently formed by fixing it to the tsuba (3) surface. At least one pair of a front projection and a rear projection, for example, is formed as a pressure member for correction in the length direction as follows. That is, the upper long rod (6) (one of the 71 pairs of long rods (6) is formed with at least one protrusion (9) protruding outward, and the other long rod (7) is formed with At least one protrusion σIt-, a protrusion (
9), there is a space @ in which the cathode lug row Y of the electrode plate group E can be inserted when the piston rod is inactive and in its extended state in the drawing, and a space @ exists behind the projection (9). Similarly, the lower rod (6) should be formed protrudingly opposite to the
One long rod (6) of the +71 pair has a space between it and the protrusion (9) that allows the anode lug row Y of the electrode plate group Z to be inserted, and is located behind the protrusion [9]. Opposing protrusions (10e) are formed protrudingly.Thus, in conjunction with the instantaneous retraction operation vc of the piston rod (1b) of the piston H, the front and rear protrusions (31) move closer to each other, and at the same time the protrusions (2 pairs of upper and lower long rods of the U-shaped frame connected to 31 (3), respectively (6) (71 and (61 + 71), respectively, in the 6 pairs, the long rods instantaneously move in opposite directions, and as a result, The front and rear projections !91 (IG, (9)elG) located opposite to each other move instantaneously toward each other, but at this time, if inserted between the front and rear projections, The cathode ear row and the anode ear row have their frontmost and rearmost ears respectively connected to their respective front protrusions f.

In this way, each pair of upper and lower long rods (63 (71 and (6
1 (71) serve as cooperating rods that move in opposite directions for the correction of the cathode and anode ear rows, respectively.

In the illustrated embodiment, in order to be able to correct the ear rows of a plurality of electrode plate groups at the same time, a pair of upper parts are provided, and vJ has several front protrusions f9) +9)... and rear protrusions (1). (I Ql・

Next, the operation of the above device, and therefore also an embodiment of the lug row of the plate group according to the invention, will be explained.

When it is necessary to correct the lug row of the electrode plate group, for example, when it is necessary to correct both the cathode lug row and the anode lug row, the plate group holding device (not shown) is used to hold the plate on its side. hold,
E row Y of the cathode plate group? A pair of upper rods (6

It collides with the frontmost ear e and the rearmost ear e of the anode ear row Y from the outside, and at the same time instantaneously pressurizes and bends both ends of the ears inward. Thus, as the piston rod moves forward, the piston rod expands, the distance between the piston rods increases,
6th first string Rokugen 101 emotion 101 ＾ Eight hato and small return are also restored to the state of bowing down and solid A.

Thus, a plate group E with corrected reprints is obtained.

Next, as shown in the fourth diagram, this is inserted into the recess m of a predetermined cathode strap forming mold M, and then the electrode plate group E, which has a cast strap of a predetermined size in one body, is assembled. can get. In the same manner, the entire row of corrective anode ears can be inserted into the recesses of a predetermined anode strap forming mold, and a similarly good cast strap can be obtained in one piece. An example of a preferred general correction method is to move the outermost ears inward by about 5 meters from the tip to 5 tin, folding the tips of the ears inward by about 30. A bent correction ear row is obtained, and since the foregoing front and rear correction protrusions cause instantaneous and strong folding, complete correction can be achieved without the need for pack cushions as in the prior art.

When correcting both or one of the cathode reprint and positive reprint of the electrode plate group, it is not necessary to provide one pair of long rods at the top and bottom corresponding to the respective reprints as in the above embodiment. At least one pair of front and rear protrusions provided on each of the long rods may be used to sequentially correct the cathode reprint and the anode ear row.

Instead of the above-mentioned embodiment, one of the prongs (31) is immovable, and the long rod pair is provided on the upper or lower surface of the cylinder, and the electrode plate group is placed upside down or in the normal position. It may also be possible to maintain it and correct its re-publication.

Furthermore, in place of the above-described embodiment, it is of course possible to perform the entire reprint correction in conjunction with the extension of the piston rod.

(Effects of the Invention) As described above, according to the present invention, the opposing pressure member is caused to collide with both outermost ears of the reissue of the electrode plate group in conjunction with the operation of the piston rod of the piston cylinder, thereby instantaneously Because the ears are bent inward by pressure, the inwardly bent ears do not create a back cushion like in the past.
This has the effect of reliably correcting the reprint.
