Abstract

The invention discloses a pair of hand-operated rotating disc mechanical strong shears. The hand-operated rotating disc mechanical strong shears comprise a threaded rotating disc, an upper rotating disc cover, a lower rotating disc cover, a rotating handle, utensil reinforcement claws and utensil shearing claws. The threaded rotating disc is installed between the lower rotating disc cover and the upper rotating disc cover. The central axes of a first central circular hole of the upper rotating disc cover, a second central circular hole of the threaded rotating disc and a third central circular hole of the lower rotating disc cover coincide with one another, and the radii of the first central circular hole, the second central circular hole and the third central circular hole are the same. One end of the rotating handle on the threaded rotating disc extends out of an arc-shaped groove hole in the lower rotating disc cover. At least four radial groove holes in the upper rotating disc cover are distributed in two diameter lines of the upper rotating disc cover. The two utensil reinforcement claws are arranged in two of the radial groove holes respectively, and the two shearing claws are arranged in the other two radial groove holes respectively. Each utensil reinforcement claw comprises a threaded claw body and a threaded arc plate which are connected through a spring. The bottoms of the threaded claw bodies and the bottoms of the shearing claws are each meshed with the threaded rotating disc. Shearing blades are arranged at the front ends of the shearing claws. The hand-operated rotating disc mechanical strong shears are easy to operate, convenient to carry, low in manufacturing cost and easy to maintain.

Technical field

The present invention relates to engineering machinery field, particularly a kind of manual turntable mechanical type forced shears.

Background technology

At present, forced shears has been applied to every field at home, such as shear reinforcement, steel wire rope, cable etc., but the forced shears on market is mainly based on electronic or hydraulic tool, because the reasons such as cutting implement volume is large, Heavy Weight are subject to the restriction of field of employment, and be not easy to carry, cannot realize shearing under narrow field and non-transformer condition.And hydraulic shear maintaining is difficult, hydraulic oil temperature influence is comparatively large, cost is high.

Summary of the invention

The object of this invention is to provide a kind of simple to operate, easy to carry, cheap, maintaining simple manual turntable mechanical type forced shears.

The present invention achieves the above object by the following technical programs:

A kind of manual turntable mechanical type forced shears, comprises screw thread rotating disk, top rotary table lid, lower rotary table lid, turning handle, pawl is reinforced by implements, pawl sheared by implements; Screw thread rotating disk is arranged between lower rotary table lid and top rotary table lid, and top rotary table lid and lower rotary table cancelling connect; The central shaft of the 3rd center hole of the first center hole of top rotary table lid, the second center hole of screw thread rotating disk and lower rotary table lid overlaps and radius is equal; Turning handle one end is fixed on screw thread rotating disk, and the arc groove hole that the other end covers from lower rotary table stretches out;

The radial slotted eye of described top rotary table lid has four at least, is distributed on two diameter lines of top rotary table lid respectively; Be distributed in two radial slotted eyes on a diameter line and two implements reinforcing pawls are installed respectively, install two in another two radial slotted eyes respectively and shear pawls;

Described implements are reinforced pawl and are comprised the screwed claw and screw thread arc plate that are connected by spring, and screw thread arc plate is for clamping implements to be sheared; The bottom of screwed claw and the bottom of shearing pawl are engaged with screw thread rotating disk respectively;

There is shear-blade the front end of described shearing pawl.

Described lower rotary table lid is fixed on grillage.

Outstanding advantages of the present invention is:

1, simplified construction of the present invention, makes cheap, and simultaneously because turning handle has the larger arm of force, can provide larger snap-in force, shearing force is strong.

2, the present invention is simple to operate, easy to carry, cheap, maintaining simple, and applicability is wide.

3, the present invention is manual operation mode, compares hydraulic shear, driven shearing, and one can reduce the noise pollution to environment, and two can save the energy.

Detailed description of the invention

Below by way of accompanying drawing, technical scheme of the present invention is described further.

A kind of manual turntable mechanical type forced shears, comprises screw thread rotating disk 10, top rotary table lid 12, lower rotary table lid 4, turning handle 7, pawl is reinforced by implements, pawl 14 sheared by implements;

Described implements are reinforced pawl and are comprised screwed claw 17, spring 16 and screw thread arc plate 18, are connected between screwed claw 17 and screw thread arc plate 18 by spring 16.

Lower rotary table lid 4 is connected with grillage 1 pin with the second pin-and-hole 3 by the first pin-and-hole 2, screw thread rotating disk 10 is arranged between lower rotary table lid 4 and top rotary table lid 12, and the turning handle 7 be fixed on screw thread rotating disk 10 stretches out the arc groove hole 5 on lower rotary table lid 4 and is limited in arc groove hole 5 and rotates; Top rotary table lid 12 is connected with the 4th pin-and-hole 15 pin by the 3rd pin-and-hole 8 with lower rotary table lid 4, and the central shaft of the 3rd center hole 9 of the first center hole 19 of top rotary table lid, the second center hole 11 of screw thread rotating disk and lower rotary table lid overlaps and radius is equal; Pawl reinforced by implements and implements shearing pawl 14 is arranged in the radial slotted eye 13 of top rotary table lid 12 respectively,

The radial slotted eye 13 of top rotary table lid 12 has four, is distributed on two diameter lines of top rotary table lid 12 respectively; Be distributed in two radial slotted eyes 13 on a diameter line and install two implements reinforcing pawls respectively, implements reinforcing pawl is limited in radial slotted eye 13 and radially moves; Install two in another two radial slotted eyes 13 respectively and shear pawl 14; Shearing pawl 14 is limited in radial slotted eye 13 and radially moves;

Described implements are reinforced pawl and are comprised the screwed claw 17 and screw thread arc plate 18 that are connected by spring 16, and screw thread arc plate 18 is for clamping implements to be sheared; The bottom of screwed claw 17 and the bottom of shearing pawl 14 are engaged with screw thread rotating disk 10 respectively; There is shear-blade 20 front end of shearing pawl 14.

When using forced shears of the present invention, pass treating first center hole 19 of shearing implements from top rotary table lid, the second center hole 11 of screw thread rotating disk and the 3rd center hole 9 of lower rotary table lid, rotating turning handle 7 drives screw thread rotating disk 10 to rotate, the screwed claw 17 making implements reinforce pawl does radial motion to center, and two implements reinforcing pawls are held tightly and waited to shear implements.Two shearing pawls 14 also do radial motion respectively to center simultaneously; Be rotated further turning handle 7, shear pawl 14 for two and continue to do radial motion to center, shear-blade 20 is sheared and waits to shear implements.
