Description

A kind of manual turntable mechanical type forced shears

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 had been applied to every field at home, such as shear reinforcement, steel wire rope, cable etc., but city Forced shears on field is mainly based on electronic or hydraulic tool, because the reasons such as big, the Heavy Weight of cutting implement volume are made use Restriction, and not readily portable, cannot realize shearing under the conditions of narrow field and non-transformer.And hydraulic shear maintaining difficulty, Hydraulic oil temperature influence is relatively big, cost is high.

Summary of the invention

It is an object of the invention to provide a kind of simple to operate, easy to carry, cheap, maintaining simple manual turntable machine Tool formula forced shears.

The present invention reaches above-mentioned purpose by the following technical programs:

A kind of manual turntable mechanical type forced shears, including screw thread rotating disk, top rotary table lid, lower rotary table lid, turning handle, implements reinforce pawl, 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；Top rotary table The central shaft coincidence of the 3rd center hole of the first center hole, the second center hole of screw thread rotating disk and the lower rotary table lid of lid and half Footpath is equal；Turning handle one end is fixed on screw thread rotating disk, and other end arc groove hole from lower rotary table lid stretches out；

The radial direction slotted eye of described top rotary table lid has four, is respectively distributed on two diameter lines of top rotary table lid；It is distributed in one directly On radial line two radially slotted eye is respectively mounted two implements and reinforces pawl, another two radially slotted eye is respectively mounted two implements and cuts Cut pawl；

Screwed claw and the screw thread arc plate that pawl includes being connected reinforced by spring by described implements, and screw thread arc plate is used for clamping to be waited to shear Implements；The bottom of screwed claw and implements are sheared the bottom of pawl and are engaged with screw thread rotating disk respectively；

The front end of pawl sheared by described implements shear-blade.

Described lower rotary table lid is fixed on grillage.

The present invention has the prominent advantages that:

1, the present invention simplifies structure so that cheap, simultaneously because turning handle has the bigger arm of force, it is provided that relatively Big gmatjpdumamics, shearing force is strong.

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

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

Fig. 2 is the back appearance schematic diagram of the manual turntable mechanical type forced shears of the present invention.

Fig. 3 is the structural blast schematic diagram of the manual turntable mechanical type forced shears of the present invention.

Detailed description of the invention

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

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

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

Lower rotary table lid 4 is connected with grillage 1 pin by the first pin-and-hole 2 and the second pin-and-hole 3, and screw thread rotating disk 10 is arranged on lower rotary table lid Between 4 and top rotary table lid 12, the turning handle 7 being fixed on screw thread rotating disk 10 stretches out the arc groove hole 5 on lower rotary table lid 4 and quilt Rotate in being limited in arc groove hole 5；Top rotary table lid 12 and lower rotary table lid 4 are connected by the 3rd pin-and-hole 8 and the 4th pin-and-hole 15 pin, 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 Central shaft overlaps and radius is equal；Pawl reinforced by implements and implements are sheared pawl 14 and are separately mounted to the radial direction slotted eye 13 of top rotary table lid 12 In,

The radial direction slotted eye 13 of top rotary table lid 12 has four, is respectively distributed on two diameter lines of top rotary table lid 12；It is distributed in one Being respectively mounted two implements on bar diameter line two radially slotted eye 13 and reinforce pawl, implements are reinforced pawl and are limited in radially slotted eye Radially move in 13；Another two radially slotted eye 13 is respectively mounted two implements and shears pawl 14；It is limited that pawl 14 sheared by implements Radially move in radial direction slotted eye 13；

Screwed claw 17 and the screw thread arc plate 18 that pawl includes being connected reinforced by spring 16 by described implements, and screw thread arc plate 18 is used In clamping implements to be sheared；The bottom of screwed claw 17 and implements are sheared the bottom of pawl 14 and are engaged with screw thread rotating disk 10 respectively； The front end of pawl 14 sheared by implements shear-blade 20.

Use forced shears of the present invention time, by implements to be sheared from the first center hole 19 of top rotary table lid, screw thread rotating disk second 3rd center hole 9 of heart circular hole 11 and lower rotary table lid passes, rotates turning handle 7 and drive screw thread rotating disk 10 to rotate, make implements The screwed claw 17 reinforcing pawl makees radial motion to center, and two implements are reinforced pawl and held implements to be sheared tightly.Two implements are sheared simultaneously Pawl 14 makees radial motion to center the most respectively；Being rotated further turning handle 7, two implements are sheared pawl 14 and are continued to make radially fortune to center Dynamic, make shear-blade 20 shear implements to be sheared.
