(54) CUTTING SCISSORS MOVING MILLS

(57) The invention relates to the processing of metals by pressure and can be used for cutting moving stock. The purpose of the invention is to reduce the metal consumption, reduce the size. and expanding technological capabilities. But the scissors contain a frame 1, a hinge 3 connected through the axis 2 by means of axis 2. A knife 4 and a clamping 5 are fixed on the tandem 3. In the guides 5 there is a slider 6 with a second knife fixed on it 7. The connecting rod 9 is connected to the slider by means of a garnish 8. Iatun 9 is freely mounted on the crank neck 10 of the crank shaft 1 1. The root journals 12 of the shaft 11 are mounted in a tandem 3. There is also an engine 13 and a gear 15 mounted in the housing 14 of the gear 15. Its driven wheel 16 is rigidly fixed to the crank neck 10 of the crank shaft 11. The gear 14 of the gear transmission 15 is made in one piece with the connecting rod 9 on which the engine 13 is mounted on the bracket 17. The scissors structure allows reducing their dimensions along the axis of the crank shaft 51. 2 Il.

The invention relates to the processing of metals by pressure and can be used for cutting moving steel,

The aim of the invention is to reduce the metal consumption, reduce the size and expansion of technological in the future.

Figure 1 shows the kinematic scheme, general view; figure 2 - section A-L in Fig, 1 ..

The proposed scissors contain a bed 1, an axis 3 which is pivotally connected to it through axis 2, on which is fixed a knife 4 and guides 5, slider 6 mounted on them movably with a second knife 7 fixed on it by means of a hinge 8 a crank 9, mounted on a crank neck 10 of a crank shaft 11 cores, necks 12 of which are installed in a master 3, an engine 13 and a gear 15 mounted in the housing 14, the driven wheel 16 of which is rigidly fixed on the crank neck 10 of a crank of shaft 11, the housing 14 is the gear 15 formed integrally with the rod 9 as a single item with multiple National - connectors, for easy assembly. The engine 13 is mounted on the connecting rod 9, namely, the bracket 17, which is made in one piece with the connecting rod. To provide certainty of the initial position of the scissors, on the base 1 a damping stop 18 is installed, on which the basic 3 rests against the balancing mechanism 1 9.

Scissors work as follows.

In the initial position, the mandrel 3 rests on the anvil 18, the crank neck 10 of the crankshaft shaft II is in its lowest position. The gap between the knives 4 and 7 maximum

The workpiece 20 passes freely between the blades 4 and 7. If necessary, the cut is made to turn on the motor 13, which transmits motion through the gear train 15, the crank shaft 11, the connecting rod 9 and the slider 6 to the lower knife 7. The lower knife 7, input - In contact with the workpiece 20, raises it towards the upper knife 4 and, after the crank shaft 11 completes half a turn, the workpiece will be cut. During the cutting, the workpiece 20 rotates with respect to the axis 2 connecting it with the frame 1. After the end of the cutting, the crank shaft 1I continues to rotate, returning to its original position. After the knives 4 and 7 have come out of contact with the workpiece 20, the mandrel 3 is returned to its original position by the action of the trimming mechanism 19. Engine 13 is turned off. Scissors are ready for metal cutting again.

Claims (1)

Formula invented and Scissors for cutting moving workpieces containing a frame pivotally connected to the shaft with a knife fixed on it and guides mounted in the slide rails with another knife connected to a crank shaft, the root necks of which are installed in the arch by means of a connecting rod; a gear mounted therein and an engine, distinguished by the fact that, in order to reduce metal consumption and expand technological capabilities, the driven gear wheel is rigidly fixed to the crank neck shaft, gear housing is made in one piece with the connecting rod, and the engine is mounted on the connecting rod. / w FI.1
