Device.
Background technique
Currently, the shear structure of existing micro electrical tube pin, typically passes through screw thread by the piston rod of cylinder
Directly be connected with cutout, cutout be limited in one in rectangle guide pad slot in, the leading flank of cutout front end and
Top surface constitute blade and and the pin aperture of upper cover plate collectively form the sound twolip for shearing pin, when work, the piston of cylinder
Bar pushes directly on cutout and advances in the guide groove of guide pad, and preceding terminal knife edge and upper cover plate are cooperatively realized to pin
Shearing.
This connection structure first is that cylinder and cutout are rigid connection, is difficult to ensure two in manufacture there are two defects
Symmetry requirement, the i.e. centre of motion line of piston rod have the deviation installed relative to the symmetrical centre of cutout；And cutout
Symmetrical centre and guide pad symmetrical centre there is also foozle, the two errors are superimposed and very likely make piston
The bar centre of motion and the cutout centre of motion are inconsistent, and cutout is as a result caused to suppress strength operation, serious wear, gas in guide groove
Source power consumption increases, and the shear service life shortens.
Second defect is that the edge line on cutout is perpendicularly to the direction of movement, and belongs to orthogonal cutting or orthogonal cutting, this
Cutting is not brisk, and impact force is big, easy tipping, is also unfavorable for the service life of device, and the uneven cutting edge of pin is whole, and pin
Easily leave loose ends at shearing separation, we have proposed a kind of shearing hookups of micro electrical tube pin thus.

The guide groove of structure, the inner wall of the guide groove slidably connect cutout, the side of the cutout open up it is fluted, it is described
The side of cutout is fixedly installed with the buckle of covering groove, and the side of the buckle offers movable span, the inside of movable span
Movable sleeve is connected to piston rod, and the outer ring of the piston rod has been fixedly attached limited block, and the cylindrical body that limited block is stepped, institute
It states piston rod and stretches out the threaded one end of buckle and be connected with spherical nut positioned inside grooves, be equipped at the top of the guide pad
Mounting plate, and the top of guide pad symmetrically offers the first bolt hole positioned at guide groove two sides, and mounting plate and guide pad it
Between be threaded with the first nut inside the first bolt hole, one end at the top of the mounting plate is equipped with fastening plates.
Preferably, the piston rod is fixedly connected with cylinder far from one end of cutout.
Preferably, the cutout offers the fixation hole in arranged in matrix, and buckle and shearing close to piston rod side
Second bolt in the portion of being located in mounting hole is threaded between block.
Preferably, symmetrically arranged fastener hole is offered at the top of the fastening plates, the internal whorl of fastener hole is connected with
Third bolt, and the screw top of third bolt-through mounting plate and guide pad connects.
Preferably, the angle of shear A at the top of the cutout is in degree setting, and the shear surface of cutout is oblique.
Compared with prior art, the beneficial effects of the utility model are: in the utility model, by being equipped with guiding
It is block, guide groove, cutout, buckle, piston rod, limited block, 7 ball nuts, cylinder, mounting plate, the first nut, fastening plates, recessed
Slot, under the cooperation of each component, spherical geometry characteristic of the flexibly jointed chain mode due to ball nut, it can be ensured that cylinder thrust and
The cutout direction of motion is parallel, not to be freed from other External force interferences caused by decentraction, avoids and suppresses the generation of strength phenomenon, and
And its sword line and the direction of motion are in 70 degree, and intrinsic 90 degree of orthogonal cuttings are become inclined cutting, when making work, pin by
Shearing force from vertical and horizontal both direction is become " clipping " from original " touch and cut ", and cutting becomes brisk, reduces punching
Power is hit, the service life of cutter and device is improved, while also improving the processing quality of pin part shear surface.
