Abstract

The utility model relates to a pure-rolling armoring-steel-tape shearing machine. The pure-rolling armoring-steel-tape shearing machine comprises two parallel rotating shafts, a plurality of disc blades, a plurality of space rings and a plurality of rubber rings, and a plurality of blind holes with the radial axes are formed in the outer cylindrical surfaces of the space rings; a plurality of cylindrical rubber nails with the radial axes are arranged on the inner walls of ring holes of the rubber rings, and the number of the cylindrical rubber nails is equal to that of the blind holes of the space rings; the rubber nails are embedded in the blind holes inside the space rings in a counterpoint mode. The pure-rolling armoring-steel-tape shearing machine has the advantages that the space rings can be fixedly connected with the rubber rings, and the defect that the space rings and the rubber rings are driven by friction force to cause slipping is overcome effectively; pure rolling is achieved between the rubber rings and a steel tape, and therefore cutting speed of every two opposite disc blades and traveling speed of the steel tape are consistent, a sheared edge is smooth, the surface of the steel tape is flat, and shearing efficiency is high; the rubber rings are good in elasticity retainability, constant in clamping force, long in service life and low in cost.

Description

A kind of pure rolling armouring tape cutter

Technical field

The utility model relates to a kind of armouring tape cutter, relates in particular to a kind of pure rolling shear constitution of armouring tape cutter, belongs to machinery manufacturing technology field.

Background technology

Existing armouring tape cutter is to be rolled and sheared by several cylinder blades to phase interlock.Be specially and several cylinder blade be to interlocking pattern arranged with interval on two rotating shafts, utilize the external cylindrical surface of two phase blade and the crossing right angle of blade plane to form shearing edge, when two rotating shafts rotate to two different directions respectively, armouring tape is under the rubber ring clamping tractive being provided with between two adjacent knife blades, move ahead on one side, Yi Bian be subject to continuous shearing.There is the irregular problem of armouring tape gait of march in such steel band shearing machine, the phenomenon stopping and going often occurs in production practices.Trace it to its cause: be owing to skidding between the circle hole of rubber ring and the metal spacer ring external cylindrical surface of support rubber circle, cause rubber ring with rotating shaft rotation, rubber ring are with cylinder blade rotation asynchronous, not cause.Thus, master workers adopt the pretightning force of adjusting clamping steel band to solve conventionally, form the distance between two rubber rings that clamp jaw by adjustment that is:, and the method that increases the resilient clamp power of rubber ring solves.This method can only solve needing of a period of time, often this in the past the elasticity of rubber ring weaken gradually, form vicious circle, its holding function also loses gradually, therefore changes the very high frequency of rubber ring.In addition,, along with the distance between two clamping rubber rings reduces, the penetraction depth of two relative cylinder blades and cut-in angle also increase thereupon, the difficulty that not only makes steel band enter shearing edge strengthens, advancing of steel band is obstructed, and the steel band out-of-flatness after shearing, and distortion is serious.

Summary of the invention

Interrupted for existing armouring tape cutter clamping steel band, to cause steel band to stop and go technical deficiency, the utility model provides a kind of pure rolling armouring tape cutter.

Technical solution adopted in the utility model is: a kind of pure rolling armouring tape cutter, comprise by bearing and support two parallel shafts that are connected in frame, many the cylinder blades of arranged with interval on two rotating shaft external diameters respectively, be placed in one or many spacer rings between two adjacent knife blades, be placed on the rubber ring on spacer ring external diameter, be placed in respectively the relative cylinder blade of two in two rotating shafts and form interlock sheared edge, be placed on the external diameter that rubber ring external diameter on spacer ring external diameter is greater than cylinder blade, it is characterized in that:

The external cylindrical surface of described spacer ring is provided with the radial blind hole of a plurality of axis;

Described blind hole distributes along the external diameter even circumferential of spacer ring;

The circle hole inwall of described rubber ring is provided with the radial cylindrical rubber nail of a plurality of axis;

Described rubber tack is uniformly distributed along the circle hole inwall of rubber ring, and quantity equates with spacer ring blind hole quantity; The diameter of described rubber tack is greater than the blind hole diameter on spacer ring external cylindrical surface;

Described a plurality of rubber tack contraposition is inlayed in a plurality of blind holes in spacer ring.

Compare with existing armouring tape cutter, of the present utility model have contribution to be:

1, between spacer ring and rubber ring, can achieve a fixed connection, effectively make up between spacer ring and rubber ring and driven the caused drawback of skidding by frictional force;

2, between rubber ring and steel band, be pure rolling, thereby the two relative shear rates of cylinder blade and the speed of travel of steel band are at the uniform velocity synchronizeed, sheared edge is smooth, and steel band face is smooth, and shear efficiency is high.

3, the elasticity retentivity of rubber ring is good, and chucking power is permanent, long service life, and cost is low.

The specific embodiment

As shown in accompanying

drawing

1,2,3, the utility model comprises by bearing and supports upper rotating shaft 5 and the lower rotary shaft 3 being connected on support 6, and upper rotating shaft 5 and lower rotary shaft 3 are parallel to each other; Support 6 is fixedly connected with in frame 1;

Many cylinder blade 8 difference arranged with intervals are on the external diameter of upper rotating shaft 5 and lower rotary shaft 3; Spacer ring 9,9 ', 9 ' ' be placed between two adjacent cylinder blades 8; On the external diameter of rubber ring 10,10 ', 10 ' ' be placed on respectively spacer ring 9,9 ', 9 ' '; Be placed in respectively the relative cylinder blade 8 of two in two rotating shafts and form interlock sheared edge; ' external diameter on rubber ring 10,10 ', 10 ' ' external diameter is greater than the external diameter of cylinder blade 8 to be placed on spacer ring 9,9 ', 9 '; Spacer ring 9,9 ', 9 ' ' external cylindrical surface on be respectively equipped with the radial blind hole 901 of a plurality of axis, blind hole 901 is along spacer ring 9,9 ', 9 ' ' external diameter even circumferential distribute; Rubber ring 10,10 ', 10 ' ' circle hole inwall be provided with the radial cylindrical rubber of a plurality of axis nail 1001, rubber tack 1001 is along rubber ring 10,10 ', 10 ' ' circle hole inwall be uniformly distributed, and quantity and spacer ring 9,9 ', 9 ' ' in the quantity of blind hole separately equate; The diameter of rubber tack 1001 is greater than spacer ring 9,9 ', 9 ' ' blind hole 901 diameters on external cylindrical surface; A plurality of rubber tack 1001 contrapositions are inlayed at spacer ring 9,9 ', 9 ' ' in a plurality of blind holes 901 in.

In blind hole 901 that external cylindrical surface is provided with that the utility model is by rubber ring 10,10 ', 10 ' ' be respectively equipped with on inwall rubber tack 1001 inlay respectively at spacer ring 9,9 ', 9 ' ', effectively realize rubber ring 10,10 ', 10 ' being connected separately between ' with spacer ring 9,9 ', 9 ' ', there will not be skidding between the two.When upper rotating shaft 5 and lower rotary shaft 3 are under the drive of reductor 2 during relative rotation, rubber ring 10,10 ', 10 ' ' clamping steel band make pure rolling, the shear rate of two relative cylinder blades 8 discharges with from wide cut steel coil strip 7 and the steel band speed of travel that enters in shear zone is at the uniform velocity synchronizeed, armouring tape 4 sheared edges after shearing are smooth, zone face is smooth, and shearing work efficiency is high.
