Description
Technical field
The present invention relates to a kind of devices for carrying out in and being oriented to bar used on bar straightener, belong to metal
Bar technical field of mechanical processing.
Background technology
The technological process of WIRE FINISHING LINE line is：Feeding → aligning → chamfered edge → ball blast → surface, internal flaw detection → collection →
Bundling → storage of weighing.Straightener is used for first of finishing procedure as the important equipment of whole finishing line, to ensureing bar
Straightness, the processing for facilitating subsequent handling, promoted subsequent handling processing accuracy play an important role.Two-roll reeler is a kind of
Using the concave, convex straightening roll of hyperbola roll shape as core component, the equipment aligned using 3 recurvation principles to pole,
Flattening precision is high, but straightening roll does not have centering guiding role in itself, the centering guider that roll gap both sides need to be relied on to set up, to quilt
The bar of aligning is oriented to and limits its transverse shifting, and bar is made to pass through straightener along suitable aligning path always, reaches strong
The purpose of straight bar.
The centering guider of two-roll reeler generally comprises two bar position-limiting units for being symmetricly set on roll gap both sides,
Each bar position-limiting unit includes guide plate door, guide and guard item, foreplate and two locking cylinders, the lower part of guide plate door and passes through horizontal rotating shaft
It is connect with straightener base rotation, guide and guard item gear is in roll gap side and passes through foreplate and is connect with guide plate door, and two locking cylinders divide
Not Wei Yu guide plate door left and right upper lateral part, the axis of the two is parallel with the shaft of guide plate door, and the cylinder body of each locking cylinder is fixed on
On straightener general frame, the piston rod of locking cylinder is withstood on guide plate door.Existing centering guider has the following disadvantages：
First, the cylinder body of locking cylinder is fixed on straightener general frame, and piston rod is withstood on guide plate door, due to the volume of piston rod
It is small, light-weight, when guide plate door in straightener operational process by greater impact when, piston rod is easy to occur with guide plate door acute
Strong vibration leads to locking cylinder oil leak, which not only adds the maintenance cost of equipment, and seriously affected production it is normal into
Row.
2nd, respectively from left and right side compression guide plate door, the contact surface of piston rod and guide plate door is the piston rod of two locking cylinders
Perpendicular to the plane of piston rod axis, the simple frictional force by between piston rod and guide plate door prevents the outside side-sway of guide plate door
Dynamic, guide plate door cannot be locked effectively, when especially producing the large scale rod bar that supplied materials curvature is big, yield strength is high, guide plate
The vibrations and activity interval of door increase, and bar material straightening precision declines to a great extent, and can not meet production requirement.
Invention content
It is an object of the invention to be directed to the drawback of the prior art, a kind of straightener bar centering guider is provided, with

Specific embodiment
Referring to Fig. 1~Fig. 5, straightener main body（Without main motor and drive shaft）Including：Straightener general frame（Containing aligning
Machine base, straightener prestressed stand 4 and straightener prestressing force column 8）, upper straightening roll 1, lead in lower straightening roll 7 and bar pair
To device, wherein, bar centering guider mainly includes two bar position-limiting units, and each bar position-limiting unit includes locking
Cylinder 2, guide and guard item 6, foreplate 9, guide plate door 10, hydraulic pressure support bar 11, shaft 12, guide sleeve 18 and locating piece 19.Guide and guard item 6 is pacified
Dress is fixed on the most inner side of foreplate 9, replaceable, and guide and guard item 6 can be contacted with bar, ensures bar centering.
Two-roll straightening machine have up and down two straightening rolls, upper straightening roll 1 be recessed roller, lower straightening roll 7 be convex roller, processed stick
Material 3 passes through roll gap along the length direction of roll gap between two straightening rolls, since straightening roll does not in itself have bar capacity of orientation, stick
Material by straightening roll bending force when the certralizing ability by two bar position-limiting units on one side, can be needed by force by stick to being pressed against
Material is strapped in roll gap, and bar is aligned by the straightening roll of hyperbola roll shape, reaches optimal leveling effect.Straightener
The bar specification of aligning is bigger, and the eccentric force that when aligning generates is bigger, guide plate also bigger to the impact force of guide and guard item and guide plate door
Door 10, which must be locked reliably, just can guarantee that bar is not extruded roll gap.
Straightener is equipped with stepless pressure charging system, Hydrauservo System, lazy-tongs, hyper-pressure pressure-loss protection system.Locking cylinder 2
There are four, it is separately fixed on four straightener prestressing force columns, each guide plate door is locked respectively by two locking cylinders in left and right
Tightly.Two-roll reeler is consolidated there are four prestressing force column and the straightener prestressed stand being formed by welding by steel plate including guide plate door
Determine shaft, be all fixed on aligning machine base.
Compared with traditional bar centering guider, the invention has the characteristics that：
1st, original frictional force is turned using the Morse taper contact surface of original creation between locking cylinder 2 of the invention and guide plate door 10
Shearing force is turned to, substantially increases coupling mechanism force, the locking of guide plate door has been effectively ensured, makes guide plate door that there is enough shock resistances
Ability reduces guide plate door Oscillation Amplitude, so as to ensure that the accuracy of alignment during bar material straightening.
2nd, on the basis of original assembly space size constancy, it is proposed that new mentality of designing, hydraulic locking cylinder is by original
Cylinder body fix, piston rod action be improved to piston rod fix, cylinder body activity, and increase the diameter of cylinder body to the maximum extent,
So as to increase the impact resistance of locking cylinder, the frequent generation of oil leakage fault is avoided, extends the service life of locking cylinder,
The maintenance cost of equipment is reduced, ensure that being normally carried out for production.
3rd, by the design of original creation, fluid pressure line is mounted on by original outside hydraulic cylinder, is changed to bore in piston rod inner
Through-hole connects external hydraulic system from piston rod end, is equivalent to and fluid pressure line is built in piston rod, greatly buffering with
The vibration for being transmitted to pipe interface is degraded, while reliability is improved, also saves external mounting space.
The course of work of the present invention is as follows：
After system pressure is pressurized by pressure charging system, into locking cylinder 2, the cylinder body of locking cylinder 2 is moved to guide plate door, locking cylinder 2
The Morse conicity locking head 13 of end is withstood on the locking face of guide plate door 10, and guide plate door 10 is prevented to pass through at this time from swinging out
The guide and guard item 6 that foreplate 9 is connect with guide plate door 10 can not be displaced outwardly, the limiting of the guide and guard item 6 of two bar position-limiting units
Effect can ensure in the roll gap that bar is always positioned between upper straightening roll 1 and lower straightening roll 7, improve flattening precision.Hydraulic system
Ensure that each locking cylinder is kept strokes using synchronous valve.
When opening guide plate door is needed to be adjusted foreplate 9 and guide and guard item 6, hydraulic system commutation, reset system opens
Dynamic, the cylinder body reverse movement of locking cylinder 2, Morse conicity locking head 13 leaves guide plate door 10, the unlock of guide plate door, and guide plate door is just at this time
It can open.
