Abstract

The invention relates to the field of machinery, and provides a buffering cutting punching tool. The buffering cutting punching tool comprises a handle, a screw, an outer cutting ring, a spring, a pressing sleeve, an inner cutting ring and a jackscrew, wherein the outer cutting ring is connected to the handle in a sleeved mode, the outer cutting ring is fixed to the handle through the screw, the handle abuts against the tail end of the inner cutting ring, the handle is fixedly connected with the inner cutting ring through the jackscrew, the pressing sleeve is arranged between the outer cutting ring and the inner cutting ring, the smaller end of the pressing sleeve extends out of a cutting edge of the outer cutting ring for 1-2mm, the spring is installed between the outer cutting ring and the inner cutting ring, and the two ends of the spring make contact with the pressing sleeve and the handle respectively. The buffering cutting punching tool cannot be limited by softness of processed materials, processing of annular parts with the size of 5-150mm can be carried out, cutting punching forming of ultra-thin non-metallic materials can be smoothly carried out through the buffering cutting punching tool, the processed parts cannot deform, and the requirement for the accurate size can be met.

Description

Buffering is cut the instrument of punching

Technical field

The present invention relates to mechanical field, particularly a kind of buffering is cut the instrument of punching.

Background technology

During ultra-thin nonmetallic materials as silk, TR thin rubber, thin plastics, diaphanous tabbies etc., because their quality is very soft, when the various shape of shearing, can only complete processing with special-purpose cutting implement, because these special-purpose cutting implements are not carried out compacting in advance, smooth and location to adding material when shearing part, make the processed part completing because of very soft, the yielding requirement that does not reach expection of texture material, sometimes also can cause scrapping of part.

Summary of the invention

The technical problem to be solved in the present invention: the invention provides a kind of buffering and cut the instrument of punching, for ultra-thin nonmetallic materials are cut to shapes such as being washed into annular, circle, make the processed part completing indeformable, and can guarantee accurate dimension requirement.

Technical scheme of the present invention: a kind of buffering is cut the instrument of punching, comprise: handle, screw, outer cutting ring, spring, gland, interior cutting ring, jackscrew, outer shroud broach shell is connected on handle, with screw, outer cutting ring is fixed on handle, handle withstands on the tail end of interior cutting ring, with jackscrew, handle is fixedly connected with interior cutting ring, gland is between outer cutting ring and interior cutting ring, its small end stretches out outer 1 ~ 2 millimeter of outer shroud edge, spring fitting is between outer cutting ring and interior cutting ring, and both ends of the spring contacts with gland, handle respectively.

Further, the front end of above-mentioned handle is annular step, ring-shaped step endoporus, ring-shaped step external diameter, has 4 screwed holes the mid portion of ring-shaped step is radially uniform, on the rear end of handle, have one flat.

Further, the inside of above-mentioned outer cutting ring is stepped hole, macropore, aperture, and outer front end is tapering inclined-plane, and aperture and tapering inclined-plane intersect formation cutting edge, and the other end of outer cutting ring radially has two, two Hole chamfering holes unthreaded hole.

Further, above-mentioned gland inside is through hole, the large footpath of outer steps axle, path.

Further, above-mentioned inner cutter is inner has a tapering face for its one end of through hole, and the external diameter of tapering face and inner cutter intersects formation cutting edge, and the other end of inner cutter radially has two tapering blind holes.

Beneficial effect of the present invention: this cuts the restriction that the instrument of punching is not subject to machined material softness, can processing dimension from the processing of 5 ~ 150mm ring-shaped work pieces, by this, cut the instrument of punching, can swimmingly ultra-thin nonmetallic materials be cut to punching forming, make the processed part completing indeformable, and can guarantee accurate dimension requirement.

The specific embodiment

Concrete structure of the present invention is provided by the following drawings explanation and embodiment.

Cut the instrument of punching, comprising: handle 1, screw 2, outer cutting ring 3, spring 4, gland 5, interior cutting ring 6, jackscrew 7.

First gland 5 being installed in outer cutting ring 3, matches with the macropore 13 of outer cutting ring 3 in the gland 5 large footpaths 20 of outer steps axle, and gland 5 paths 21 stretch out outer cutting ring 3, and path 21 exceeds the about 1 ~ 2mm of cutting edge 16.Spring 4 is installed on to the inside of outer cutting ring 3 again, then interior cutting ring 6 is packed in gland 5, handle 1 contacts with the tail end of outer cutting ring 3, with screw 2, is fixedly connected.Handle 1 contacts with the tail end of interior cutting ring 6, with jackscrew 7, is fixedly connected.

The instrument of punching of cutting combining is put on the material that will be cut punching, at this moment gland 5 is contacted prior to cutting the material of punching, and machined material pressing, compacting are determined to cut and rush position, then afterburning at the afterbody of handle 5, at this moment

outer cutting ring

3,6 shearing works simultaneously of interior cutting ring, because afterbody and the spring 4 of gland 5 joins, at this moment gland 5 is retracted outer cutting ring 3 bodies, outer cutting ring 3, interior cutting ring 6 complete shearing work.When cutting the instrument of punching, leave machined material when surface, it is external that spring 4 is released outer cutting ring 3 by gland 5, and the ring-shaped work pieces that gland 5 is also sheared outer cutting ring 3, interior cutting ring 6 simultaneously, from outer cutting ring 3, the middle release of interior cutting ring 6, completes the processing of part.

outer cutting ring

For the softer material of the quality such as ultrathin film, cutting while rushing, by gland 5, press and scrape the part that material will stay, interior cutting ring and outer cutting ring cut simultaneously, and the part that can make material stay is like this indeformable, and can guarantee accurate dimension requirement.In addition, after interior cutting ring and outer cutting ring cut, upwards mention buffering and cut the instrument of punching, spring 4 will promote gland 5 forward, make part that material stays from interior cutting ring and complete exiting between cutting ring.
