Description
Technical field
The utility model belongs to a kind of steel rolling equipment.
Background technology
The abrasion of groove needs frequently to change roll in System on Rolling Steel.Efficiency is changed to improve, compression production is accurate
The standby time, roll, which is changed, to be changed together with mill stand.
Fig. 1 is the locking form of the mill stand of prior art 1.
Slidable small footprint 6 is installed on base 100, is fixed and connected with four fitted bolts of big nut 5 in small footprint 6
The milling train 200 with roll is connect, the locking cylinder 1 of oil cylinder form is installed in the side of small footprint 6, as shown in Figure 2 on base 100
The latch segment 11 of the cylinder rod end of locking cylinder 1, which stretches out to be pressed in above small footprint 6, makes its fastening irremovable, on milling train 200
The roll shaft of roll stretch into spindle carrier 4 and with spindle carrier 4 with reference to and can by driving rotate.The cylinder of hydraulic cylinder 2 as shown in Figure 3
Boom end is connected with small footprint 6 with bearing pin 3.
When changing milling train 200, locking cylinder 1 unclamps, and hydraulic cylinder 2 promotes small footprint 6 to be moved together with the milling train 200 above it
It is dynamic, after milling train 200 disengages with spindle carrier 4, then milling train 200 is promoted to hanging out position.Locking cylinder 1 is led because built-in disc spring piece number is few
Cause retraction stroke it is extremely short, latch segment 11 can not completely disengaged small footprint 6, cause milling train 200 connect small footprint 6 can not be with milling train
200 hang out together；And hydraulic cylinder 2 and the connector bearing pin 3 of small footprint 6 are not suitable for frequently dismounting.If this locking scheme is more
Change milling train 200, it is necessary to four big nuts 5 for connecting milling train 200 and small footprint 6 are removed, make small footprint 6 de- with milling train 200
Milling train 5 can be hung out from after.
Four big nuts 5 dismount time-consuming, and especially in the Operational preparation time, changing milling train 200 has the time of half
Consume in the disassembly and installation fastening to this big nut 5.The Operational preparation time is extended, reduces production efficiency.
Fig. 2 is that the mill stand of prior art 2 locks scheme.
In order to avoid dismounting four big nuts online, by the way of mill stand is integrally hung out.
Small footprint breach 61 is set in small footprint 6 as shown in Figure 4, when hydraulic cylinder 2 together pushes away milling train 200 and small footprint 6
To when hanging out position, small footprint breach 61 is just directed at the latch segment of the cylinder rod end of locking cylinder 1.And small footprint 6 and hydraulic pressure
The connection of cylinder 2 is also changed to the form that plate 31 quickly connects by bearing pin connection, namely as shown in Figure 5 with being connected with small footprint 6
Plate 31 is inserted in the groove set by the cylinder rod end of hydraulic cylinder 2.After so the plate 31 of small footprint 6 and hydraulic cylinder 2 are disengaged, when
Hydraulic cylinder 2 is together shifted milling train 200 and small footprint 6 onto when hanging out position, milling train 200 can not have to unclamp four big nuts 5 and with
Small footprint 6 is overall together to be hung out, integral replacing.
Milling train 200 is hung out by the way of the latch segment of the cylinder rod end of the alignment locking cylinder 1 of small footprint breach 61, can be significantly
The reduction replacing construction of milling train 200, but this breach, tightened up requirement is proposed to lifting, be easy to because being swung during lifting
Milling train 200 is caused not playback quickly, and slightly dislocation will hit the head of locking cylinder 1, cause locking cylinder 1 to damage.Plate
31 form fixer cylinder pressures 2 and the connection of small footprint 6, though disengage quickly hydraulic cylinder 2 and small footprint 6, the knot of plate 31
Structure is complicated, can not extract out or be seated because deforming plate 31 often.
Utility model content
The utility model provides a kind of horizontal mill quick replacement device, and the purpose is to solve to lack existing for prior art
Point, the efficiency of replacing milling train is substantially improved.
Technical scheme is used by the utility model solves its technical problem：
A kind of horizontal mill quick replacement device, slidable small footprint is installed on base, matched somebody with somebody in small footprint with nut
Close bolt and be fixedly connected with the milling train with roll, the locking cylinder of oil cylinder form is installed on base in the side of small footprint, lock
The latch segment of the cylinder rod end of cylinder, which stretches out to be pressed in above small footprint, makes that its fastening is irremovable, and the roll shaft of the roll on milling train is stretched
Enter spindle carrier and with spindle carrier with reference to and can by driving rotate, it is characterised in that：The locking of the cylinder rod end of locking cylinder
Block, which stretches out, can be pressed in above small footprint, and the latch segment retraction of the cylinder rod end of locking cylinder can leave the space directly over small footprint；
Spindle carrier is slidably mounted on base, and cylinder rod end and the spindle carrier of hydraulic cylinder are connected, and are horizontally through with latch
The two is connected by spindle carrier with small footprint.
It is of the present utility model to be beneficial in that：
The utility model need to only unclamp locking cylinder when changing milling train, after unclamping spindle carrier and small footprint hydraulic bolt, i.e.,
Milling train can be hung out.The Operational preparation time greatly shortens, and changes rolling mill efficiency and is substantially improved, and operation is more convenient, and locking cylinder is not yet
It is fragile.
