Description
Technical field
The present invention relates to metallurgical finishing fields, and especially, the present invention relates to a kind of band steel burrs for Precise asymptotics to repair
Mill apparatus and its adjustment method.
Background technology
So far, in order to meet requirement of the different user for strip width, Precise asymptotics are provided with strip trimming
Device --- circle shear, to carry out flanging processing to the strip after disk sheared edge.
However, equipment feature of the circle shear due to its own, also can be such that the edge of strip occurs during working process
Burr.In general, in Precise asymptotics, can also pressure burring machine be used to carry out flanging processing, institute to the strip after disk sheared edge
Stating the operation principle of pressure burring machine is, using roller or wheel with certain roll shape, extrusion process is carried out to steel edge portion.
But in fact, since pressure burring machine is only by burr " pressure ", and not by burr " elimination ", that is, the processing is to control
It marks and does not effect a permanent cure, this just brings certain hidden danger to subsequent production.For example, carrying out following process to strip in downstream user
When, it often appears in the phenomenon that after strip progress punching press or after firing, the burr of the strip edge of pressure tilts again.
As a result, in order to fundamentally solve the problems, such as production that burr is brought, it is necessary to burr " reconditioning " is fallen, rather than it is simple
" pressure ".
On the other hand, presently, there are the equipment generally existing problems with such as band steel burr arrangement for grinding：
1, the equipment occupation spaces such as described band steel burr arrangement for grinding are big, heavy, are added in unit often to other
Equipment causes to interfere；
2, reconditioning effect unobvious；
3, because of the interference with the equipment such as steel burr arrangement for grinding Yu unit technique, and draw new production problem；
4, for different strips, must also structure adjusting reconditioning height, reconditioning angle and reconditioning power just can guarantee it is final
Grinding quality, but presently, there are most of burr arrangement for grinding can not neatly carry out reconditioning height, angle and reconditioning power
Adjustment；
5, some arrangement for grinding targeted designs are excessively single, it is difficult to adapt to the variation of strip steel specification.
For this purpose, there is an urgent need in the art to one kind to occupy little space, reconditioning elevation angle and reconditioning power are adjustable and be suitable for band
Steel advises declinable band steel burr arrangement for grinding and its adjustment method.
Invention content
To overcome many disadvantages existing for above-mentioned current band steel burr arrangement for grinding, goal of the invention of the invention to be：
A kind of band steel burr arrangement for grinding and its adjustment method for Precise asymptotics be provided, it is described for Precise asymptotics
Band steel burr arrangement for grinding and its adjustment method deft design, occupy little space, reconditioning elevation angle and reconditioning power it is adjustable and
It is suitable for the band steel burr reconditioning of strip steel specification variation.
Band steel burr arrangement for grinding and its adjustment method according to the present invention for Precise asymptotics can be set not introducing
Under the premise of standby interference and technique interference, veining defect caused by being sheared due to circle shear is fundamentally solved, strip edge is improved
Portion's quality.
The technical solution with steel burr arrangement for grinding for Precise asymptotics of the present invention is as follows：
A kind of band steel burr arrangement for grinding for Precise asymptotics, including the adjustment locking of transverse feed mechanism, level angle
Mechanism, vertical angles adjustment retaining mechanism and be set on vertical angles adjustment retaining mechanism, for band steel burr into
The emery wheel of row reconditioning, it is described to be used to adjust emery wheel with respect to the setting direction of strip, angle of inclination, side with steel burr arrangement for grinding
To, contact position, mill pressure etc., which is characterized in that
The transverse feed mechanism with steel burr arrangement for grinding for so that be able to run along track, so that emery wheel is suitable
The variation of strip steel specification is answered,
The level angle adjustment retaining mechanism is set on the transverse feed mechanism, including under the motor of bolted on connection
Pedestal 12 in pedestal 10 and motor, pedestal 12 is provided with the waist rotated for the two relative level in motor lower bottom base 10 and motor
Hole sliding slot and bolt arrangement wherein for fixing, loose bolts so that in motor pedestal 12 can relative level rotation, tighten waist
