SU21190A1 - Press for quenching and bending of spring leaves - Google Patents

Description

The invention relates to presses for hardening and bending of spring sheets and provided with ribbed pads for this purpose. In the proposed press, the clamping spring strips of the pads are provided with grooves that slide along the main guides of the board with openings for the passage of water, and are connected to each other by earrings, which allow the casing to move apart for a certain distance.

In FIG. 1 is a front view of a press; FIG. 2 - its top view; FIG. 3 is a side view of it; FIG. 4 - section of the press along the central axis.

On the main board 1 (Figs. 1 and 2), there are guides 2 attached to it by bolts 18. On the foH, two steel strips 3 and six strips 4 are placed on the same board. All strips are equally spaced from one another and screwed to the board 1 and serve to facilitate the movement of the b-16 blocks (Fig. 3). The block 16 is fixedly fixed to the board 1 with bolts 19. The guides 2 which are included in the grooves in the blocks b-16 are used to ensure the exact stroke of the blocks. 6 is connected to the clamping screw 5, and the remaining pads are interconnected by an earguard 20 and serving These are used to push the pads apart for a certain distance. The circular holes 21 (Figs. 2 and 4) are intended for the rapid passage of water.

The work process is as follows. Two workers are laying hot sheets 17 between the pads apart. Then one of them actuates the clamping screw 5 to compress these pads, after which the board 1 is lowered into the water with the sheets sandwiched between the pads. The water quickly enters the holes 21, giving quenching to the sheets, and the board 1 rises again. The pads are moved apart using screw 5, the sheets are released and removed by the workers, and then transferred to the spring for release, after which the spring is ready for assembly.

The subject matter of the invention.

Press for hardening and bending of spring leaves, equipped with ribbed pads, characterized in that pads 6-16, used for clamping strips between them, constituting the spring, by means of one clamping screw 5, are provided with grooves sliding along the guides 2 of the main board 1 with openings 21 for the passage of water and are connected by intertwinkle earrings 20, allowing the shoes to be moved apart for a certain distance.
