Description

Plug-type reciprocal shearing scissors

Technical field

The present invention relates to cutting implement technical fields, more particularly, to a kind of plug-type reciprocal shearing scissors.

Background technique

In the equipment of the automatic jobs such as shearing branch, the scissors that can back and forth form shear action is often required to use. But the most structure of common scissors is complex, it is not easy to operate.

Summary of the invention

In view of the deficiency of the prior art, the object of the present invention is to provide a kind of plug-type reciprocal shearing scissors, It has the characteristics that structure is simple, easily operated.

To achieve the goals above, the technical scheme adopted by the invention is that: plug-type reciprocal shearing scissors, including work Frame is fixed with stationary knife on the falsework, and has and be hinged on the falsework in the middle part of a moving knife, and the right part upper side edge of the stationary knife has Lower blade, the moving knife right part lower side there is upper knife edge, the lower blade and the upper knife edge match, and the left part of the moving knife is equipped with Strip shape gob, when the upper knife edge is in open configuration with the lower blade, which integrally moves towards to be that right end is higher, left end is lower It is skewed, meanwhile, on the falsework sliding be provided with can move left and right but movable block not moving up and down, the movement The right part of block is equipped with connecting shaft, which is slidably fastened in the strip shape gob relative to the strip shape gob, and, the movement Block is connected with reciprocator.

It is arranged with pulley in the connecting shaft, which is fastened in the strip shape gob.

The strip shape gob is in " people " font that middle part is protruded to the left relative to the top and bottom of the strip shape gob.

The stationary knife is fixed on the falsework by least two screw, and a left side for the stationary knife is hinged in the middle part of the moving knife Above portion.

After adopting the above structure, the invention has the advantages that compared with the prior art: structure is simple, easily operated. When in use, stationary knife is in stationary state to plug-type reciprocal shearing scissors of the invention, and after movable block moves back and forth, Neng Goutong The mode for pushing away, drawing is crossed, the left part of moving knife is driven to move up and down, then upper knife edge formation moves up and down and lower knife-edge is at shearing Movement.Due to only needing that the shear action of circulation can be formed by back and forth moving left and right for movable block, so structure is relatively simple, Operation is also relatively easy to.

Detailed description of the invention

Present invention will be further explained below with reference to the attached drawings and examples:

Fig. 1 is the main view of the plug-type reciprocal shearing scissors in original state of the embodiment of the present invention；

Fig. 2 is the schematic diagram of section components section view in Fig. 1；

Fig. 3 is the main view of the plug-type reciprocal shearing scissors in shearing condition of the embodiment of the present invention；

Fig. 4 is the schematic diagram of section components section view in Fig. 3.

Specific embodiment

Embodiment, as shown in figures 1 to 4: plug-type reciprocal shearing scissors, including falsework 10.It is solid on the falsework 10 Surely there is stationary knife 20, and have and be hinged on the falsework 10 in the middle part of a moving knife 30.In the present embodiment, which passes through at least two Screw is fixed on the falsework 10, and the middle part of the moving knife 30 is hinged above the left part of the stationary knife 20 that then the moving knife 30 is indirect Be hinged on the falsework 10.Meanwhile the right part upper side edge of the stationary knife 20 has on the downside of the right part of lower blade 21, the moving knife 30 Side has upper knife edge 31, and the lower blade 21 and the upper knife edge 31 match.That is, the lower blade 21 is in fixed state, it should After upper knife edge 31 moves up and down and the lower blade 21 forms shear action.

Further say:

The left part of the moving knife 30 is equipped with strip shape gob 32.The whole trend of the strip shape gob 32 is inclined for right end is higher, left end is lower It is ramp-like.That is, when the upper knife edge 31 and the lower blade 21 are in open configuration, alternatively, the mistake moved up and down in the upper knife edge 31 Cheng Zhong, alternatively, the whole trend of the strip shape gob 32 is the right side when the upper knife edge 31 and the lower blade 21 are in the shearing condition clamped End is higher, left end is lower skewed.So-called entirety is oblique, generally refers to no matter have which kind of shape in the middle part of strip shape gob 32 Shape, the right end of the strip shape gob 32 is higher always, the left end of the strip shape gob 32 is lower always.Meanwhile it sliding and setting on the falsework 10 Still movable block 40 not moving up and down can be moved left and right by being equipped with, and the right part of the movable block 40 is equipped with connecting shaft 41, the company Spindle 41 is slidably fastened in the strip shape gob 32 relative to the strip shape gob 32.And the movable block 40 is connected with reciprocating engine Structure (is not shown) on figure, and reciprocator can be crank link mechanism etc., thus the movement that there is left and right to move back and forth.In this way, After the movable block 40 or so moves back and forth, which is forced by the strip shape gob 32 and is moved down on the left part of the moving knife 30 It is dynamic, correspondingly, the upper knife edge 31 of 30 right part of moving knife moves up and down and the lower blade 21 constantly forms shear action.

Optimization:

It is arranged with pulley 42 in the connecting shaft 41, which is fastened in the strip shape gob 32.In this way, making power transmitting more It is smooth.

The strip shape gob 32 is in " people " font that middle part is protruded to the left relative to the top and bottom of the strip shape gob 32.This Sample, conducive to push pull maneuver is formed, make the upper knife edge 31 to move up and down speed more uniform.

The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations Technical field, be included within the scope of the present invention.
