Description

In the production of Gall chains, internal links are assembled under a hand press in the following way: the link plate is placed on the press cushion, the sleeve is directed onto the plate opening with the left hand, and the press lever is pressed with the right hand, after which the sleeve is pressed. The same operation is performed with the second sleeve being pressed in; Moreover, the sleeves are often misaligned in the link plate, which must be straightened with a hammer. After pressing, two rollers are put on and then the link plates are put with the holes upwards, the right hand is pressed on the ends of the sleeve with the help of a press, and the link is made ready. With this manual assembly method, it takes a lot of time.
For the shortcomings of the manual assembly of the Gaul chains, a special adaptation is generally applied to the drive presses, in which the link plates are mounted on a spring-loaded forked lever, and the riveting of the drill
TIKES of heads, etc., are given when moving a pressure stamp. In order to speed up the process, these devices are supplied with spring pushers rigidly connected to the ram of the pressure stamp, so that when the ram is raised, the assembled Gall. To control the start and end of the expulsion from the matrix of finished products, a fixedly mounted part is used with various shaped surfaces that interact with the pushers of the pushers.
According to the invention, in order to restore the position of the ejector for installing new star plates before the end of the return stroke of the slide, the clamp bar acting on the ejector when the slide is moved back is rotatable and fixed on the rods connected to the press slide. Rotation of the bar is made under the influence of
on the way of its course part with a shaped surface.
In FIG. 1 is a perspective view of a proposed press attachment; Fig, 2 is a view of a chain link; FIG. 3 is a front view of a device mounted on the press, with a partial cut; FIG. same side view.
On the press table 4 (figs. 3, 4), the block 7 is fastened with the help of clamping strips 5, provided with two protrusions / 5 corresponding to the openings in the bushes d of the link (fig. 2) of the chain. The distance between these protrusions 13 corresponds to the pitch of the chain to be assembled. The board 7 is attached to the shoe 7, having a cutout corresponding to the contour of the plate from the link; In the middle part of the cut-out in the block 7 there is a hole for the passage of the spring ejector 9. On the press ram there is a reinforcement punch 14 and links 7 carrying a spring-loaded bar 8 with a cutout on it to rotate it under the action of the shaped surface of the part 77 fixedly attached to the table press.
When assembling the chain, a strip c is inserted into the notch of the board 2, and sleeves d are put on the protrusions 13 and the b links of the chain link are put on them. By means of tweezers 75, a plate is taken from the link and overlapped somewhat obliquely with respect to the sleeves in order to more correctly get the sleeves into the holes of the plate.
When the press is turned on, the upper and lower plates with and the sleeves d are pressed in by the punch 74. When the slider moves up together with tamy 7, bar 8 is loaded, loaded with spring 16, Plank 8 rests on ejector 9 and through the latter the assembled link is pushed out of protrusions 13 from cut 2 of board 2. When the slider approaches the upper extreme position, bar 8 slides along the wedge the shaped surface of the part 77, compresses the spring 16 and rotates, so that the ejector P, using its spring 10 resting on the ring 12 fixed on it, comes to its original position and frees the cutout in the board 2 d Placing a new link. When the slider moves down, the strap 8 slides along the shaped surface of the part 77 and, at the lower position of the slider, under the action of its spring 75 turns to its original position and fits under the ejector to act upon it after assembling the next link of its link.
The subject matter of the invention.
Attachment to a press for assembling links of Gall chains, using a punch and a matrix with a spring ejector and a guide for a pressure, ejector bar with a shaped piece fastened on. The press table is characterized in that the pressure bar 8 of the ejector 9, which interacts with the shaped surface of the part 77 and is fixed on the legs 7 connected to the floor, is pivoted in order to disengage it from the ejector before the end of the return stroke of the slide block.
