SU63133A1 - Device for feeding blanks in consecutive dies located around the circumference - Google Patents

Description

The proposed device is intended for the delivery of blanks in circumferentially positive dies, which serve for mass production of small objects, in particular shoe blocks, which are used as pistons for threading shoes in shoes, various leather products, and so on.

The usual process for the production of such block-tape metal is that THAT is first produced so-called stabbing (small flat plates), which then enters the .HI stores of the MG-molding horizontal section where it is made. For this, in each press there is a matrix, it is pressed into the hammer by a punch made in the form of Rod. With rounded edges of the end face. From the matrix, the product is a injection of & gates drupkm STAR. A: The complete production of a shoe block is done in four operations, so that this

Four separate presses are required; the transfer of blanks from one press to another is still carried out manually.

In order to unite all operations for the manufacture of blocks in one unit, it is advisable to arrange successive dies around the circumference - “send the workpieces to them by periodically turning the disk on which they are fixed at the time of all operations performed.

In this case, all successive dies and the corresponding punches can be placed kg of one HONOR, for example, on / hcrules, and repeated on the remaining three quarters, so that the unit will actually replace the small press & s.

In order to accomplish this and the proposed tool, it serves to feed the workpieces in successive chips located around the circumference. With this goal, on a periodically turning-IV-E € мом Disk - strengthened Lena s-taps in the form of ticks, which are controlled by radially mounted sliders in the disk, which are located under the influence of Könnus driven for forward-shear movements of it in the axial direction. Sponges, tongs are made stepwise for the possibilities of 1xHV, product attack In equal stages of production With a flange and without megap .... ,:.,. : .. In FIG. 1 shows a longitudinal axial section of the tool, FIG. 2 shows a disk with entrances fixed on it, and FIG. 3, 4 and 5 - a section in the direction of the arrow A Hia of FIG. 2 one of the details of the device with; logging; VKO In equal stages of its manufacture. Actually, the grip is made in the form of a tick located on the circumference of the disk 13: 28 (Fig. 2), consisting of two halves rotating on a pin 23. These ladles are opened for guaranteeing stabbing or blockage and already holding them. to transfer the workpiece from. one operation to another by turning the entire disk with ticks attached to it. The opening and closing of ticks is carried out with the help of a slider 1B1 26, pressing down on the bevels of polo-vino ticks. Sliders for closing ticks receive movement from the action: on them of a cone (Fig. 1) fixed on the rod 7, making return-ight transfer from the swinging crank 3 with its fingers coming between the shoulders 4 at the end of the rod 7. The gripping jaw sponges are, as it were, two-stage in their working part: the bottom 31 of them (Fig. 3) has a larger receptacle designed for Za (x1 cola, and the top "part 32 seizes the already protruded stab. the choke always gets into the bottom of the tick And as soon as kolot been converted to slugs, although would have after the first pulldown, one; fi .verhnyuyu gets only a part of pincers having prismatic jaws grip). On . 4 shows the batt of Ze, which is lost in the chaos, a; FIG. 5 - LOK 36 is shown, the flange which is located above the upper plane of the tongs and the hull is clamped by their prism (with TIIC jaws. The work proceeds as follows. Punches 37 -, (Fig. 4- and 5). 34 (Fig. 5),; back 27 and front 29 of which are shown in Fig. 2. These ribs are used to remove the blocks from the pockets when the punches come out of the dies. The punches have grooves 33 (Fig. 5) for the ribs In this case, the flag of the block of blocks is always located between the ribs and the upper plane of the halves of the ticks and, moreover, the body of the block ., always h, pressed with prismatic jaws. When the poissons enter the matrices, by the way, block, the grippers (pincers) open until the poacoons come out of the matrices, after which they close and the edges the iQ punches are removed from the block, and the tick disc is rotated by a step between the punches. Stab from. Everyday stores come through channel 11 (Fig. 1) with a continuous stream of BI channels 25 (FKG. 2) and rests on the bottom CG: for ticks. The feeders 30 pick up the stakes and, in a stretch of wa; the way its knives 24, pushing it into the nests of ticks. The finished block falls into the wide holes of the dies, which are located in the corresponding places of the disk. By, for products (the scotch 35, block 36) are the matrix, not shown in the drawing. FIG. 1 matrix disk is marked with number 10, point of a disk with disk is number 15, and the ejector fixed in disk 8 is number 9. The latter through rods 1, traverse 2 and springs are fed to the matrix D | K |: ku and OWN pins pushes the block. Figures 5 and 6 of the designation of Ch. Are stop and DELITE. Common discs of a conventional type. Eccentric mounted on shaft 18 19

by means of ralica 17, the slider 16 is fed forward, equipped with a shank 22 loaded with a spring 21. The slider 16 and its head 12 carries punches 37. The dividing apparatus is informed by the movement of a well-developed eccentric mechanism.

Subject invention

Claims (2)

1. Tool for filing the overhang in consecutive circles located around the circumference, characterized by the use of the grippers in the form of ticks fixed on a periodically rotated disk, for the control of which are slide rails 26 installed radially in the disk, which are under the action of a cone connected with the drive for (reciprocating movements in the axial direction). 2. The filling form of the apparatus according to claim 1, characterized in that the pliers jaws are stepped in order to be able to grip articles with and without a flange.
