Abstract
The utility model discloses a shearing device for strips, which comprises an upper sleeve, a lower sleeve and an elastic reset part, wherein the elastic reset part is mounted between the upper sleeve and the lower sleeve which are sleeved mutually. The upper sleeve is provided with an upper shearing opening, and the lower sleeve is provided with a lower shearing opening matched with the upper shearing opening. By means of the shearing device for strips, the conventional strip shearing way is modified, shearing efficiency is effectively improved, and sections of sheared strips are more attractive. Moreover, the shearing device for strips is simple in structure and convenient in operation.
Description
Technical field
The utility model relates to a kind of cutting implement, is specifically related to a kind of device of shearing bar that is exclusively used in.
Background technology
Bar is comparatively general in daily life, like shoestring, rope, cable etc., all belongs to bar; Generally, in process of manufacture, need the bar of first one-step forming be sheared; Be processed as finished product so that use; For example, shoestring factory need cut off the shoestring five equilibrium of restricting, and forms shoestring.
Existing bar shear history all is to adopt traditional scissors to operate, like cutting off of shoestring; Be through the scissors cutting, cutting off of some metal wire rods is to operate through the metal shears cutting nipper; The instrument of the shearing bar of this quasi-tradition; Its service speed is slower, and use is convenient inadequately, has had a strong impact on the speed of cutting off of bar.
The utility model content
To the deficiency of prior art, the purpose of the utility model aims to provide a kind of efficient height and bar shear easy to use cut off.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The shear of bar; Comprise the top external member, and the bottom external member of said top external member socket and be installed in the top external member and the bottom external member between elastic reset spare; Said top external member is provided with a top sheared edge, said bottom external member be provided with one with the bottom sheared edge of said top sheared edge coupling.
Said top external member and bottom external member all are cylindrical tube shape, and said top external member slip cap is connected on the outside of said bottom external member.
Said top sheared edge is opened on the barrel of said top external member, and said bottom sheared edge is opened on the barrel of said bottom external member.
Also be provided with on the external member of said top with the top material of said top sheared edge conducting and put groove, also be provided with on the external member of said bottom with the sheared edge conducting of said bottom and with the bottom material that said top material is put groove coupling and put groove.
Said elastic reset spare is a spring, and the top is provided with a spring bearing housing on the external member of said bottom, and the last top of said upper component also is provided with a hand-held pressure contact portion, and two free ends of said spring are connected on said spring bearing housing and the hand-held pressure contact portion.
Said bottom external member is provided with a limit shaft, said top external member be provided with one with the stopper slot of said limit shaft coupling.
The beneficial effect of the utility model is:
1, changes traditional bar cut mode, can effectively improve shear efficiency;
2, the section of the bar after the shearing is comparatively attractive in appearance;
3, simple in structure, easy to operate.
Description of drawings
Fig. 1 is the structural representation of the shear of a kind of bar of the utility model;
Fig. 2 is the scheme of installation of the shear of bar shown in Figure 1;
Fig. 3 is a kind of user mode sketch map of the shear of strip shown in Figure 1;
Fig. 4 is the another kind of user mode sketch map of the shear of strip shown in Figure 1.
The specific embodiment
Below, in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing:
Like Fig. 1, shown in 2; Shear for a kind of bar of the utility model; It comprises top external member 1, bottom external member 2, spring 3; The main body of top external member 1 and bottom external member 2 is cylindrical tube shape, and top external member 1 closely is socketed in the outside of bottom external member 2, and its two can slide vertically.The top is provided with a spring bearing housing 24 on bottom external member 2, and the top is provided with the press section 14 that a usefulness PVC material is processed on the top external member 1, and two free ends of spring 3 are connected on spring bearing housing 24 and the pressure contact portion 14.
On the barrel of top external member 1, offer a sheared edge 11, an epitaxial lateral overgrowth of sheared edge 11 reaches the side of top external member 1, forms a material and puts groove 12; Corresponding with it; On the barrel of bottom external member 2, offer a sheared edge 21, an epitaxial lateral overgrowth of sheared edge 21 reaches the side of bottom external member 2, forms a material and puts groove 22; Wherein sheared edge 11 is suitable with the size length and width size of sheared edge 22, and it is suitable with the length and width size of putting groove 22 to put groove 12.
As shown in Figure 3; Forefinger is pushed pressure contact portion 14, holds the lower end of bottom external member with thumb, application of force extruding; Sheared edge 21 merges with sheared edge 11; Put groove 22 and put groove 12 merging, spring 3 contractions are simultaneously inserted bar 4 sheared edge 21 and sheared edge 11 of merging with putting in the groove that forms after groove 12 merges from putting groove 22.As shown in Figure 4, the pressure of release hand, then spring 3 resiliences, the relative distance of elongation top external member 1 and bottom external member 2, then sheared edge 21 diminishes with the openings of sheared edge 11 common qualifications gradually, finally to bar 4 enforcement shearings.
In order to realize high shear, can also put the first edge on a knife or a pair of scissors at the edge of sheared edge 11 and sheared edge 21.
According to mechanical field known technology general knowledge, above-mentioned spring can also adopt other flexible members to substitute, like shell fragment, elastic gum etc.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
