Description

The bar straightening device

The utility model relates to the reinforcing bar processing unit (plant), particularly the bar straightening device.

Existing comparatively general bar straightening device is two row by a plurality of running rollers and rearranges the middle straight line path that passes through for reinforcing bar that forms.Reinforcing bar reaches the purpose of bar straightening along the bending of this straight line path through level, vertical or 45 ° of directions.Such bar straightening device, when realizing multi-thread aligning, operating difficulties.

Chinese patent ZL98252089.1 provides improved steel bar straightener.This steel bar straightener is made up of preceding straightener and back straightener, preceding straightener is made up of two groups of roller set again, each group roller set is made of a plurality of isometrical running rollers that are two row arrangements again, form the roll-in route segment of a linearity, the two groups of formed linearity roll-in of roller set route segments middle pinch roll place shape in an angle.Back straightener is made up of two running rollers.Preceding straightener is made the horizontal direction aligning, and back straightener is made the vertical direction aligning.This steel bar straightener complex structure, and all running rollers of two groups of roller set of preceding straightener are passive running roller, the power of the pinch roll before and after the transmission of the reinforcing bar of whole steel bar straightener relies on.Two groups of passive running rollers are restricted the plastic deformation that reinforcing bar produces, if need to strengthen amount of plastic deformation, then need improve the power of pinching, for this rib to Ribbed Bar produces damage.

The purpose of this utility model is to provide a kind of leveling effect good, and bar straightening device simple in structure.

At above-mentioned purpose, bar straightening device described in the utility model is made up of left and right two groups of roller set that are made of a plurality of isometrical running rollers, and a middle pinch roll is arranged between two groups of roller set, and as the center.Each group roller set is made up of the isometrical running roller of upper and lower two rows.The formed roll-in route segment of left side roller set two row's running rollers is a serpentine, and the formed roll-in route segment of right roller set two row's running rollers is anti-serpentine, two serpentine roll-in route segment slick and sly connections at middle pinch roll place, and shape is in an angle.The lower roll wheel of two groups of roller set is active roll, is driven by same drive unit.On the circumference of each running roller of two groups of roller set, all offered 2-3 hole slot.

Now with reference to the accompanying drawings the utility model is further described.

Accompanying drawing 1 is the structural representation of facing of the utility model bar straightening device.

Accompanying drawing 2 is the schematic diagram of 3 hole slots on each running roller periphery.

Accompanying drawing 3 is two path schematic diagrames that the formed roll-in route segment of roller set is formed.

Find out by Fig. 1, the utility model bar straightening device, form by left roller set A, right roller set B,

middle pinch roll

8,9, guide-in roller 2, preceding

pinch roll

3,4,

back pinch roll

13,14 and straightener roll 12, left side roller set A and right roller set B all are assemblied on the same plane of

roller seat

7,7 of roller seats are fixed on the frame 1, about among two roller set A, the B, last row forms by a plurality of

isometrical bending rolls

5,10, following row is by a plurality of

isometrical bending rolls

6,11 compositions; Guide-in roller 2 and by running roller 3, the 4 preceding pinch rolls of forming are positioned at the left end of left roller set A, by running roller 8, the 9 middle pinch rolls of forming are positioned at a left side, right two roller set A, the centre of B, straightener roll 12 is in the right of right roller set B, by running roller 13, the 14 back pinch rolls of forming are then after installing straightener roll 12, above-mentioned 3 groups of pinch rolls and straightener roll 12, guide-in roller 2 is installed on the frame 1, on the roller set A of a left side, two arrange bending rolls 5 down, 6 formed roll-in route segments are serpentine, on the right roller set B, two arrange bending rolls 10 down, 11 formed roll-in route segments are anti-serpentine, two serpentine roll-in route segments join at middle pinch roll place, and, form lambdoid angle as the summit.Guide-in roller 2, preceding

pinch roll

3 and 4,

middle pinch roll

8 and 9, straightener roll 12,

back pinch roll

13 and 14, and the upper and lower two row's bending rolls among left roller set A and the right roller set B all offer 2-3 hole slot on its periphery.

In addition, the

bending roll

5 and 11 of the following row among left roller set A and the right roller set B all links to each other with drive unit, and they are crooked running roller initiatively.

After the reinforcing bar of need aligning enters straightener from guide-in roller 2, by preceding sending

roller

3,4 are delivered in the formed serpentine roll-in of the left roller set A path, alternating bending under the staggered pressure of reinforcing bar bending roll 5 and following bending roll 6 on a plurality of in advancing, reinforcing bar is through middle pinch roll 8 subsequently, 9, enter among the right roller set B, reinforcing bar was by

middle pinch roll

8 and 9 o'clock, because angle in this formation, make reinforcing bar produce a bigger plastic deformation, reinforcing bar enters in the anti-serpentine roll-in path of right roller set B formation, again through last, two arrange the staggered pressure of

bending rolls

10 and 11, alternating bending down, so far, can be fully bar straightening, and prevent that reinforcing bar from producing torsional deflection in advancing, reinforcing bar is after carrying out straightening through straightener roll 12, enter

back pinch roll

13 and 14, promptly finish whole aligning operation.

Compared with prior art, the utlity model has following advantage:

(1) because upper and lower two row's bending rolls of left and right two roller set of the utility model is formed The roll-in route segment is respectively serpentine and reversed S-shape, and reinforcing bar stands anti-on these two route segments Multiple flexural deformation effectively realizes straightening, and " is connected " with discharging device, doffer, is front and back The connection of operation provides convenience.

(2) because all actives for being driven by drive unit of lower row's bending roll of left and right two roller set Running roller is compared with the straightening of driven roll wheel, realizing under the same straightening Plastic Deformation Conditions, owing to pinch Power is disperseed, the normal pressure of single running roller and roller muscle reduces, to rebar surface, and Ribbed Bar particularly The damage on cross rib surface reduces significantly.

(3) the utility model once can be aligned 1-3 root reinforcing bar, production efficiency height simultaneously.

(4) equipment is simple, and cost is low.
