Abstract
A kind of circle shear, includes snub pulley (1), upper pressure roller (2), pressing device (4) and disc scissors (5), and the snub pulley (1) is fixed on the platform below strip (6)；It is characterized in that the upper pressure roller (2) is fixed in shaft by the connecting lever (3) of the right and left.The present invention compresses the middle part of strip (6) by snub pulley (1) and upper pressure roller (2), it is ensured that the precision of the width dimensions after strip (6) shearing, while by the edge of pressing device (4) compression strip (6), avoid the unrestrained side defect of strip (6).
Description
Technical field
The present invention relates to steel rolling shearing equipment field, especially a kind of circle shear.
Background technique
Circle shear is generallyd use on rolling mill production line to complete the trimming of strip, the circle shear of two sides is in shearing strip
When, strip is by great extruding force following defect easy to form: 1, strip is caused middle part to be arched upward by lateral extruding force,
So that width dimensions precision does not reach requirement after strip shearing；2, the edge of strip, which is squeezed power, unevenly leads to wave
Side.
Summary of the invention
Against the above deficiency, the purpose of the present invention is to provide a kind of circle shears, include snub pulley, upper pressure roller and compression
Device, snub pulley and upper pressure roller can compress among strip when shearing steel edge portion, guarantee width dimensions after strip shearing
Precision；Pressing device can compress the edge of strip in when cutting strip steel through rotary shears edge, avoid the generation of unrestrained side defect.
The technical scheme is that being accomplished by the following way: a kind of circle shear, include snub pulley, upper pressure roller,
Pressing device and disc scissors, the snub pulley are fixed on the platform below strip；It is characterized in that the upper pressure roller
It is fixed in shaft by the connecting lever of the right and left.
The pressing device is welded on the inside of disc scissors.
Snub pulley, upper pressure roller and the pressing device is all steel heart external coated rubber.
The present invention compresses the middle part of strip by snub pulley and upper pressure roller, it is ensured that the essence of the width dimensions after strip shearing
Degree, while by the edge of pressing device compression strip, avoid the unrestrained side defect of strip.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
1 is snub pulley in figure, and 2 be upper pressure roller, and 3 be connecting lever, and 4 be pressing device, and 5 be disc scissors, and 6 be strip.
Specific embodiment
Known by Fig. 1, a kind of circle shear, includes snub pulley 1, upper pressure roller 2, pressing device 4 and disc scissors 5, it is described
Snub pulley 1 is fixed on the platform of 6 lower section of strip；The connecting lever that described 2 barrels of upper pressure roller cross the right and left is fixed in shaft, with
The rotation of shaft and lifted or depressed；The pressing device 4 is welded on the inside of disc scissors 5.
When work, upper pressure roller 2 is pushed as shaft rotates, and strip 6 is pressed between snub pulley 1 and upper pressure roller 2, band is made
Steel 6 keeps straightened condition；Snub pulley 1 and upper pressure roller 2 are by strip 6 with rotation；The disc scissors 5 of the left and right sides shear strip 6
Edge when, pressing device 4 compresses the edge of strip 6, avoids the formation on unrestrained side.
The present invention compresses the middle part of strip 6 by snub pulley 1 and upper pressure roller 2, it is ensured that the width dimensions after the shearing of strip 6
Precision, while by pressing device 4 compress strip 6 edge, avoid the unrestrained side defect of strip 6.
Claims (3)
1. a kind of circle shear includes snub pulley (1), upper pressure roller (2), pressing device (4) and disc scissors (5), under described
Carrying roller (1) is fixed on the platform below strip (6)；It is characterized in that the connecting lever that the upper pressure roller (2) passes through the right and left
(3) it is fixed in shaft.
2. a kind of circle shear according to claim 1, it is further characterized in that: the pressing device (4) is welded on disk
The inside of scissors (5).
