SU16977A1 - Scissors Modification for Metal - Google Patents

Description

In customer L 6659, scissors are described for letela, in which the upper knife is lowered by a wedge carrying it, sleep (with a pivotal toothed rack coupled to a gear mounted on the frame, on a roller which is rigidly fitted with a gear lever with a roller enclosed in a curved drive groove In the proposed modification of the described scissors instead of carrying the upper virgin, two strips are used, equipped on one side with inclined 1 protrusions entering the respective inclined slots of the caliper, moved The upper knife is achieved by moving the slats in the slots of the frame in the horizontal direction of the center by the action of loads; the movement in the opposite direction is carried out by a lever system connected by a "drive gear."

The drawing shows the view proposed. scissors for metal side.

The upper knife 1 is reinforced, in the caliper 14, in which nodal grooves of which are located protrusions 2, 2 of the laths 3, 3, are connected by a slow 1. lever 8, rotatable Sching on axis 8 and bearing a roller on the free end.9 rolling fist 7,. fixed on the great. .L: - - ,.

water shaft 6; To the bars 3, 3, in addition, by means of price 15, thrown over blocks 5.5, a load 4 is suspended, intended to lower the caliper 14 and the knife -1.

When shown in the drawing, the location of the driving mechanism of the strap 3, 3 occupy the leftmost, and the roller 9, the rightmost position. The load 4 is constantly clamping the roller 9 to the fist 7, as a result of which, when you turn the fist against the racial arrow, the roller moves from the rightmost position to the left, and the bars 3, 8, under the influence of the load J :, will start moving from left to right and with their projections 2, 2 lower the knife 1 onto the pre-cut metal bar to be cut,

During the run-in of arc a b of cam 7, roller 9 is in the extreme left position, bars 3, 3 in the extreme right, and knife I and the caliper 14 in the lowest position. At this time, the support 13 with a lower knife fixed to it on the base, through the means t connected with the crank pins of the driving gears 11, 11, will rise and cut the metal bar. After this role & 9, running in the arc: the mouth of the fist 7, will be from the left

The subject of the patent.

In addition, metal foot, which is described in patent JS 6659, is characterized in that in order to communicate the knife to the reciprocating movement of the knife, instead of one wedge, it is attached in part to the bed of the plank 3, 3, placed partially in the bed & and partly in inclined cuttings 2, 2 supporting knife 1, caliper 14, I connected by a chain with load 4 and 10 with speed 8, which is affected by fist 7 on the drive shaft 6 ..
