Description

Wide region metal plate and belt trimming device

Technical field

The present invention relates to the circle shear unit that uses in the cold finish rolling, finishing line of iron and steel and non-ferrous metal industry metal plate and belt, particularly in, the thin (trimming device of metal plate and belt of 0.2mm～4.0mm).

Background technology

Two that circle shear is misplaced up and down by two or more sets, vertical circular shear blades combine, and transfer certain side clearance and coincidence amount to shearing through the metal plate and belt between two blades.

At present at home on the cold finish rolling of metal plate and belt, the finishing line, middle thin plate (use very extensive by the cut edge circle shear of 0.2mm～4.0mm).The version of circle shear is mainly power and draws and cut, that is: cutter shaft rotational shear strip initiatively earlier when wearing band, and cutter shaft power is thrown off when coiling tension is set up after, leans on the rotation of tension force pulling cutter shaft to realize the strip shearing.As shown in Figure 3: cutting disc, preface 17 strips, preface 18 slitter edge silks, preface 19 lower disc cuttves on cutter shaft, preface 14 coincidence amount guiding mechanisms, preface 15 side clearance guiding mechanisms, the preface 16 on preface 9 drive motors, preface 10 clutches, 11 times cutter shafts of preface, preface 12 driving gear pairs, the preface 13.Wear band and when operation work cutter shaft the powershift mode, use more be jaw clutch, electromagnetic clutch or freewheel clutch (preface 10) at present, clutch is arranged between drive motors motor (preface 9) and the driving gear pair (preface 12).The deficiency that this structure exists is: cutter shaft passive rotation when shearing strip; Meanwhile cutter shaft also need drive travelling gear and power transmission shaft together rotates, and has increased the load of cutter shaft, makes when shearing the thin plate band (below the 0.6mm); The frictional force that strip produces cutter shaft is not enough to overcome the resistance of cutter shaft; It is dumb to cause cutter shaft in shear history, to rotate, and has had a strong impact on the trimming quality of metal plate and belt, also can't rotate sometimes.Because the conllinear of thin plate is sheared in can't realizing; Cold finish rolling, finishing unit are had to, and (1.0mm～4.0mm) (0.2mm～1.2mm) on different units, cut edge respectively, wherein (0.2mm～1.2mm) cut edge circle shear often adopts initiatively shear pattern to thin plate with thin plate with cut deal.Increase the input of equipment so on the one hand greatly, reduced the operational efficiency of unit on the other hand again.

Summary of the invention

For overcoming the deficiency of prior art; Goal of the invention of the present invention is to provide a kind of wide region metal plate and belt trimming device; Through realizing the quick engagement and the disengagement of cutter shaft and transmission, the flexibility that cutter shaft rotates in guaranteeing to shear, during thin plate solves the problem of thin plate shearing in can't realizing simultaneously on cold finish rolling, the finishing line; Reduction equipment drops into greatly, improves the operational efficiency of unit.

For realizing above-mentioned purpose, technical program of the present invention lies in: idle pulley has internal tooth and external tooth, and external tooth is meshed with power gear; Internal tooth is meshed with spur gear on the cutter shaft, and spur gear is connected with the cutter shaft key, and spur gear on the cutter shaft and cutter shaft are matched in clearance; Fixed dam is equipped with in the rear end of cutter shaft, and the cutter shaft front end has step, is with the push-and-pull cover on the cutter shaft; Push-and-pull is with the ripple boss, with cutter shaft be matched in clearance, push-and-pull cover and spur gear link together; Its faying face has protruding, the concave surface in location, and there is pin-and-hole the rear end of cutter shaft, and the pin-and-hole of the rear end of cutter shaft comprises front end pin-and-hole and rear end pin-and-hole; Positioner axially is positioned at the push-and-pull cover on the cutter shaft, and said wide region metal plate and belt is that thickness range is at 0.2mm～4.0mm.

Idle pulley of the present invention plays a part to form a connecting link to transmission of power, and external tooth is meshed with power gear when wearing band, accepts motor power; Internal tooth be meshed with spur gear on the cutter shaft (internal tooth transmission); Motor power is passed to cutter shaft, drive the cutter shaft rotation, realize initiatively cutting edge; Spur gear on the cutter shaft and cutter shaft are matched in clearance, and the rear end is the push-and-pull cover fixedly, through the key transferring power, simultaneously again can be under the effect of push-and-pull cover be directed at through flat key and produce axial slip on the cutter shaft, realize the engagement and the disengagement of spur gear.Like this, just can satisfy that cutter shaft is initiatively sheared strip and the function needs of the two kinds of duties that dally fully.The push-and-pull cover is processed with annular corrugated boss, is convenient to manual operation, and the boss cylindrical is fixed with fast-positioning device simultaneously, can realize axially locating fast of spur gear, prevents that effectively the course of work spur gear axial location from changing; The cutter shaft front end is processed with step, and the cutter shaft rear end face is fixed with baffle plate simultaneously, can guarantee that two kinds of different operating state spur gear fast moving put in place; Cutter shaft rear end external diameter manufactures 2 pin-and-holes, cooperates with positioner, realizes the locking of two kinds of duty spur gears.

The present invention efficiently solves power and draws to cut in passive shear history because the cutter shaft load is excessive and cause the cutter shaft rotation dumb, can't greatly reduce the equipment input to the problem that realizes than metal sheet shearing, and has improved the operational efficiency of unit.

The present invention compared with prior art has the following advantages:

1, can effectively reach the power side cut requirement of crossing process, after spur gear was thrown off simultaneously, cutter shaft was in idling conditions fully, greatly reduces the load of cutter shaft, had improved the flexibility of cutter shaft rotation when cutter shaft is passive to be sheared, and had improved the trimming quality of metal plate and belt;

2, make the circle shear processing technology scope on cold finish rolling, the finishing line obtain expansion, in can realizing, (shearing of 0.2mm～4.0mm), unit can replace the strip side cut work that can only lean on two units to realize originally to metal sheet;

3, can improve the operational efficiency of unit greatly, reduce the input cost of equipment;

4, because in unit running process, transmission system need not action, greatly reduce the noise of equipment, in the service life of having improved parts and complete machine, reduced energy consumption.
