Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

The application provides a connecting rod type scissors device, as shown in fig. 1, comprising a base 1 and a cutting part 2 for cutting cables; the cutting part 2 comprises a fixed knife 21 and a movable knife 22; the fixed knife 21 is arranged on the machine base 1; the fixed knife 21 is hinged with the movable knife 22 through a rotating shaft 3; the fixed knife 21 and the movable knife 22 are clamped to form an occlusion port; a driving mechanism 4 for driving the movable knife 22 to reciprocate relative to the fixed knife 21 so as to open or close the occlusion opening is arranged on the machine base 1; the output shaft of the driving mechanism 4 is connected with the movable knife 22.

This application mainly solves artifical cutting machine and has a large amount of sparks, has potential safety hazard, production efficiency low, produces a large amount of toxic gas and leads to the problem of workman's easy acquired occupational disease. And this application sets up one on frame 1 and can carry out the cutting part 2 of cutting to the cable, and cutting part 2 includes stationary knife 21 and movable sword 22, and the bite mouth of stationary knife 21 and movable sword 22 can be tailor to the cable, and the cable can be put into and cut in the bite mouth. The fixed knife 21 is fixed on the machine base 1, the driving mechanism 4 drives the movable knife 22 to reciprocate relative to the fixed knife 21 so as to switch the fixed knife 21 and the movable knife 22 back and forth between a closed state and an opened state, wherein one inflection point of the reciprocating motion is that the cutting parts of the fixed knife and the movable knife are closed so as to cut the cable, and the other inflection point is that the cutting parts of the fixed knife and the movable knife are opened so as to place the cable in the opened space. So as to realize the full-automatic interval cutting of the cable.

Specifically, the fixed knife and the movable knife are both made of superhard alloy steel, so that the occlusion force is large, and the occlusion range is large.

In an alternative embodiment, the drive mechanism 4 includes a reduction motor 41, a first link 42, and a second link 43; the speed reducing motor 41 is arranged on the stand 1; in particular, the geared motor 41 is fixed to the housing 1 and is equipped with a quick plug. One end of the first connecting rod 42 is sleeved on the output shaft of the speed reducing motor 41, and the other end is hinged with the second connecting rod 43 through a pin shaft; one end of the second connecting rod 43, which is far away from the first connecting rod 42, is hinged with the movable knife 22 through a pin shaft. The first link 42, the second link 43 and the movable knife 22 form a three-link mechanism, and since the movable knife 22 is hinged to the fixed knife 21 via the rotating shaft 3, that is, a certain section of the movable knife 22 is fixed by the rotating shaft 3. The rotation of the speed reducing motor 41 drives the first connecting rod 42 to rotate around the axis of the motor rotating shaft 3 in a reciprocating manner, the first connecting rod 42 drives the second connecting rod 43 to swing in a reciprocating manner, and the second connecting rod 43 drives the movable knife 22 to swing in a reciprocating manner around the rotating shaft 3 so as to realize the relative closing and opening of the movable knife 22 and the fixed knife 21, so that the cable can be cut.

Meanwhile, the rotational torque of the reduction motor 41 is converted into a gap shear force between the stationary blade 21 and the movable blade 22. Because the speed reducing motor 41 runs at a constant speed, the fixed knife 21 and the movable knife 22 are also periodically sheared. In practice, the reduction motor 41 is set for a period of about 6 times per minute. The staff only need put into the cable when the scissors is opened, and the rope will be cut.
