Abstract

The utility model discloses a kind of circle shears, it includes cutting on motor, speed reducer, upper cutter shaft, lower and the upper slitter being sheathed on respectively on cutter shaft and flexible upper broach shell, lower and flexible lower broach shell, the input axis connection of motor and speed reducer, the output shaft of speed reducer is respectively with upper cutter shaft and cutting axis connection.Advantage:1st, the utility model is provided with flexible upper broach shell on upper cutter shaft, flexible lower broach shell is provided in lower, it is arranged at side of the corresponding knife far from trimming edge, and the diameter of lower broach shell is more than the diameter cut, therefore in trimming operation, lower broach shell jacks up sheet metal strip slightly, prevents it from being contacted with the outer rigidly cut, reduces sheet metal strip and is scratched caused by cutting friction.2nd, the upper broach shell of the utility model and lower broach shell are equipped with chamfering, sheet metal strip and upper broach shell and cut that set contact area is small, and friction coefficient greatly reduces, so as to which edge plate profile fluctuation in shear history be made relatively to stablize.

Description

A kind of circle shear
Technical field:
The utility model is related to a kind of circle shears, belong to cutting metal strap equipment.
Background technology:
Circle shear is the accurate continuous longitudinal shear equipment of sheet metal strip, has especially been obtained extensively in aluminum strip processing industry Using being mainly used for the both sides edge of longitudinal shear campaign band blank, make that the band blank edge after cutting is neat, smooth, nothing Burr meets high-class size requirement of the client to aluminum foil stock different size.
Circle shear mainly include motor, the upper cutter shaft that is arranged in parallel and lower and be separately positioned on cutter shaft and under It the upper slitter of " disc " on cutter shaft and cuts, upper slitter and cutting mutually is close to, and equipped with certain lap, driven using motor Upper cutter shaft and lower rotation, and then drive upper slitter and cut rotation, occlusion band realizes cutting processing.
In order to realize the shearing of sheet metal strip, the upper slitter of existing circle shear and cutting is made of rigid, is being cut When cutting sheet metal strip, easily cause that sheet metal strip trimming is bad or surface defect;Such as:Sheet metal strip and upper slitter and cutting connects Tactile part be easy to cause scuffing, especially sheet metal strip lower part and cuts the part of contact, influences the quality of sheet metal strip.
Utility model content:
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of circle shears.
The purpose of this utility model is implemented by following technical solution, a kind of circle shear, including motor, speed reducer, upper slitter Axis, lower and it is sheathed on the upper cutter shaft and upper slitter in the lower respectively and cuts, the motor subtracts with described The input axis connection of fast machine, the output shaft of the speed reducer is respectively with the upper cutter shaft and described cutting axis connection;It is further included Broach shell and flexible lower broach shell, the upper broach shell fixing sleeve are set on the upper cutter shaft in the flexibility of " disc ", the upper broach shell It is close to side of the upper slitter far from trimming edge;
The lower broach shell fixing sleeve is set in the lower, and the set that cuts is close to described cut far from trimming edge Side;
Disk diameter of the upper broach shell close to the upper slitter side is more than the disk diameter far from the upper slitter side, shape Into upper chamfering α;The lower broach shell is more than close to the disk diameter for cutting side far from the disk diameter for cutting side, Form lower undercut ss.
Further, upper chamfering α=2 °~3 °.
Further, lower undercut ss=2 °~3 °.
Further, the upper broach shell is close to the disk diameter D of the upper slitter sideOn=dOn-2*δ;
The lower broach shell is close to the disk diameter D for cutting sideUnder=dUnder+ (0.1~0.2) mm;
Wherein dOnFor the diameter of the upper slitter, dUnderFor the diameter cut, δ is the thickness of sheet metal strip.
Further, the upper broach shell is formed from a resin.
Further, the lower broach shell is formed from a resin.
The advantages of the utility model:
1st, the utility model is provided with flexible upper broach shell on upper cutter shaft, and flexible cut is provided in lower Set is arranged at side of the corresponding knife far from trimming edge, and the diameter of lower broach shell is more than the diameter cut, therefore in trimming During operation, lower broach shell jacks up sheet metal strip slightly, prevents it from being contacted with the outer rigidly cut, reduces sheet metal strip under It is scratched caused by knife friction.
2nd, the upper broach shell of the utility model and lower broach shell are equipped with chamfering, sheet metal strip and upper broach shell and cut set contact surface Product is small, and friction coefficient greatly reduces, so as to which edge plate profile fluctuation in shear history be made relatively to stablize.
Description of the drawings:
Fig. 1 is the structure diagram of the present embodiment;
Fig. 2 is circle shear structure diagram.
In figure:Motor 1, speed reducer 2, upper cutter shaft 3, lower 4, upper slitter 5 cut 6, upper broach shell 7, lower broach shell 8.
Specific embodiment:
A kind of circle shear, including motor 1, speed reducer 2, upper cutter shaft 3, lower 4 and be sheathed on respectively upper cutter shaft 3 and under Upper slitter 5 on cutter shaft 4 and cut 6, the input axis connection of motor 1 and speed reducer 2, the output shaft of speed reducer 2 respectively with upper cutter shaft 3 It is connected with lower 4;It further includes the upper broach shell 7 of " disc " and lower broach shell 8, and upper broach shell 7 and lower broach shell 8 are formed from a resin, Upper 7 fixing sleeve of broach shell is set on upper cutter shaft 3, and upper broach shell 7 is close to side of the upper slitter 5 far from trimming edge;
Lower 8 fixing sleeve of broach shell is set in lower 4, and lower broach shell 8 is close to cut 6 sides far from trimming edge;
Disk diameter of the upper broach shell 7 close to 5 side of upper slitter is more than the disk diameter far from 5 side of upper slitter, forms 2 ° and above falls Angle α;Lower broach shell 8 is more than close to the disk diameter for cutting 6 sides far from the disk diameter for cutting 6 sides, forms 2 ° of lower undercut ss;
Upper broach shell 7 is close to the disk diameter D of 5 side of upper slitterOn=dOn-2*δ;
Lower broach shell 8 is close to the disk diameter D for cutting 6 sidesUnder=dUnder+0.2mm;
Wherein dOnFor the diameter of upper slitter 5, dUnderTo cut 6 diameter, δ is the thickness of sheet metal strip.
