Embodiment:

Below in conjunction with accompanying drawing and by specific embodiment, the invention will be further described, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.

A kind of screw shell severing wears machine, comprises core bar 10, support folder 2, clamp sleeve 5, cutting knife 7 and core bar folder 9, and described core bar is threading section 13, casing section 16, cut length 17 and the gripping section 19 of coaxially making successively, at the end face of threading section, is shaped with through wires hole 14; In the radially mirror image symmetry of corresponding core bar threading section, be respectively fixed with a support folder, this support presss from both sides by cylinder 1 Driven by Coaxial; Radially mirror image symmetry at corresponding core bar casing section is respectively fixed with a clamp sleeve, and this clamp sleeve is driven by cylinder 3, and this cylinder is driven and realized axial displacement by lead screw transmission platform 4; Radially mirror image symmetry in corresponding core bar cut length is respectively fixed with a cutting knife, and this cutting knife is driven by cylinder 6; In the radially mirror image symmetry of corresponding gripping section, be respectively fixed with a core bar folder, this core bar folder is driven by cylinder 8.

Above-mentioned core bar, support folder, clamp sleeve, cutting knife and core bar folder are installed on workbench.

In order to facilitate sleeve pipe to penetrate, prevent that the termination of core bar from passing between the gap of screw shell, at the end face of gripping section, be coaxially fixed with a spring 11, at the other end of spring, be coaxially fixedly mounted with SDeflector 12.

In order to strengthen the stability of core bar, on the gripping section that closes on cut length, be also provided with a clamp sleeve laterally driving by air cylinder driven and by lead screw transmission platform.

Do not bump against with core bar when guaranteeing that cutting knife is closed, extend the useful life of cutting knife, at the outer rim middle part of core bar cut length cylinder, be coaxially shaped with annulus feed groove 18.

In order to make sleeve pipe automatic counterboring, at the changeover portion of threading section and casing section, be shaped with the flared section 15 of taper surface.

The threading section diameter of described core bar is greater than casing section diameter, so that form flared section, the effect of flared section is gradually by the sleeve port support after cutting off greatly, is convenient to, by wire harness threading, realize the reducing transition between threading platform and core bar; Casing section is identical with the diameter of gripping section; The diameter of threading section is greater than the diameter of cut length.

Described support folder is identical with core bar clamping structure referring to Fig. 3, is rectangular structure, at a middle part, side of cuboid, is shaped with a V-type groove 20.When a pair of support folder clamps, its relative end face laminating.Support folder is used for clamping core bar, makes its location.Support folder is by air cylinder driven opening and closing.

The structure of described clamp sleeve, referring to Fig. 4, is right angle block structure, at a middle part, outer face of right angle block, is shaped with a semicircle along the axial clamping slot 21 of core bar, when after a pair of clamp sleeve closure, can clamp sleeve pipe, but not held tightly.

The structure of described cutting knife is referring to Fig. 5, and semicircular radially cutting edge 22 is made at the middle part, one end of cutting knife, when forming a circle that is slightly smaller than or equals cutting bed diameter after a pair of cutting knife closure, in the relative part of two cutter closures, is also shaped with cutting edge 23.

Its objective is and guarantee that sleeve pipe can be completely severed.

Operation principle of the present invention:

Core bar folder and the clamp sleeve of when the machine that originally wears uses, first opening gripping section, now the support of threading section folder is closed, guarantees that core bar can transverse shifting.Then, sleeve pipe is penetrated to core bar to position that clamp sleeve can clip to via guiding ball and spring from the port of gripping section; Next clamp sleeve drives sleeve pipe to move to cut length, and the distance that clamp sleeve moves is consistent with Pipe Cutting Len req.Then, cutting knife cuts off sleeve pipe, and core bar folder and the clamp sleeve of closed gripping section all no longer move core bar and sleeve pipe.The support folder of opening subsequently threading section, penetrates through wires hole by wire harness or lead-in wire, and the clamp sleeve of casing section is clamped sleeve pipe and driven it to threading section, to move subsequently, and by large casing diameter support, then clamp sleeve is opened.Now with the support folder of delay circuit control threading section, stay open state, until manually with hand, sleeve pipe is enclosed within wire harness or lead-in wire from the pull-out of threading section, then just closed.Now a duty cycle finishes, and next circulation starts, and opens core bar folder and the clamp sleeve of gripping section, threading, and clamp sleeve is clamped sleeve pipe, continues circulation.

Equipment is except starting to need to control separately the core bar folder of gripping section and clamp sleeve open, and the action of each circulation can be started by a foot switch.
