Accompanying drawing explanation
Fig. 1 is the shear structural representation in a kind of embodiment for hydraulic cold milling train.
Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the present invention is described in further detail.
Providing a kind of shear for hydraulic cold milling train in the present embodiment, this shear is for slab width
The band of band is sheared, and this shear is also used for other and arranges, and other products are carried out product shearing.
As it is shown in figure 1, this shear includes fixed mount 1, upper cutting assemblies 2, lower scissors assembly 3 and drives assembly 4.On
Cutting assemblies 2, lower scissors assembly 3 and driving assembly 4 set gradually installation from top to bottom.
Upper cutting assemblies 2 includes shears 21, upper scissors base 22 and two guide rods be arrangeding in parallel 23.Two guide rods 23 erect
Directly it is arranged on fixed mount 1.Two guide rods 23 can be arranged on fixed mount 1 up or down by sleeve, so that guide rod
23 move more stable, and guide rod 23 is arranged on fixed mount 1 by upper and lower two sleeves.Upper scissors base 22 is crossbeam, its two ends
It is respectively and fixedly installed to the upper end of two guide rods 23, and guide rod 23 part, the portion stretched out are stretched out in the two ends of upper scissors base 22
Demultiplexing is spacing in stopping.Upper shears 21 is arranged on the lower end of scissors base 22, and upper shears 21 has two downward flare ups to be preset
The blade of angle, two blades are symmetrical along device centrage, and the angle of inclination of blade can be arranged according to the actual requirements, such as with water
Flat angle is 7 °.
Lower scissors assembly 3 includes lower scissors 31 and lower scissors seat 32.The two ends of lower scissors seat 32 by sleeve can on move down
It is arranged on two guide rods 23 dynamicly, and this sleeve is between conduit 23 self up or down two sleeves.Lower scissors
31 upper ends being arranged on lower scissors seat 32, lower scissors 31 has a flat blade upwards, and lower scissors 31 is positioned at shears 21
Lower section, upper shears 21 and lower scissors 31 coordinate realization to shear.
Driving assembly 4 to include that driving cylinder 41 and crossbeam 42, driving cylinder 41 are hydraulic cylinder or cylinder, driving cylinder 41 fixedly mounts
In the lower end of lower scissors seat 32, the output shaft of driving cylinder 41 is fixing with the center fixed vertical of crossbeam 42 to be connected.Crossbeam 42 level
Arranging, the two ends of crossbeam 42 are fixing with in the lower end of two guide rods 23 respectively to be connected.Driving cylinder 41 is driven by output shaft and cuts
Knife assembly 2 moves up and down, and lower scissors assembly 3 can be driven to move up and down by counteracting force.
Being symmetrically arranged on two with two limited blocks 11 at fixed mount 1, limited block 11 is positioned at the lower section of scissors base 22, spacing
What block 11 was positioned at scissors base 22 moves down on ground track, and limited block 11 stops that upper scissors base 22 continues to move to downwards so that
The downward stroke of upper scissors base 22 is limited.The downward stroke of upper scissors base 22 can be arranged according to the actual requirements, is limited by adjustment
The position of position block 11 realizes.
In this example, the operation principle step of shear is:
S101: original state, puts into band
Driving cylinder 41 is in retracted state, and upper shears 21 is positioned at peak, and lower scissors 22 is positioned at minimum, now, above cuts
Cutter 21 and lower scissors 22 open up into maximum, are put between upper shears 21 and lower scissors 22 by band 5.
S102: upper shears 21 moves down；
The overhanging output shaft of driving cylinder 41, output shaft drives upper cutting assemblies 2 to move down by crossbeam 42, i.e. goes up shears 21
Move down, until limited piece of upper scissors base 22 11 is spacing, no longer move downward.
S103: lower scissors 31 moves up；
Driving cylinder 41 continues overhanging output shaft, owing to limited can not the continuation of upper cutting assemblies 2 moves down, passes through retroaction
Power, driving cylinder 41 and lower scissors assembly 3 are driven to movement, i.e. lower scissors 31 moves up, until coordinating with upper shears 21
Complete to shear；
S104: return back to original state.
After shearing completes, driving cylinder 41 bounces back so that upper cutting assemblies 2 and lower scissors assembly 3 return to original state position,
Circulation is sheared next time.
A kind of shear for hydraulic cold milling train that this example provides, owing to upper scissors base 22 be may move by guide rod 23
Be arranged on fixed mount 1, lower scissors seat 32 is movably mounted on guide rod 22, and driving cylinder 41 and lower scissors seat 32 and lead
Bar 23 all connects, and driving cylinder 41 can drive upper and lower scissors base to move up and down, and upper shears 21 is for having two downward flare ups
The blade of certain angle.The inclination angle of diclinic blade is big, and shearing force is little, shears band both sides simultaneously, and cutting stroke is short, speed
Hurry up, band is stable.Additionally, lower scissors seat 32 be can floating structure, during threading, lower scissors seat 32 is arranged on bottom, it is to avoid under
Blade scratches band；During shearing, lower scissors 31 can upwards float and shear band together with upper shears 21, and shear surface is the most smooth.
The present invention is illustrated by use above specific case, is only intended to help and understands the present invention, not in order to limit
The present invention processed.For those skilled in the art, according to the thought of the present invention, it is also possible to make some simply
Deduce, deform or replace.
