Abstract

A rotary reinforced bar straightening mechanism with adjustable skew roll tilt angle, which is characterized in that: three to seven gear stands (3) are arranged in alternatively backward direction and forward direction inside the combined straighten cylinder which comprises a short axle head (1), a square pillow (2), a long axle head (6) and a square pillow (7) equipped with sliding chute, the gear tooth (15) of the gear stands (3) is geared with the tooth shape of a long adjusting gear rack (8), and the long adjusting gear rack is fixed inside the sliding chute of the square pillow (7) equipped with sliding chute with a fastening blot (9). The axial cord of a skew table roll and the axial cord of the reinforced bar form a certain tilt angle which can be adjusted to adapt different models of reinforced bars. The utility model has the advantages that the operating is convenient, the work is reliable and the straightening quality and efficiency of the reinforced bar straightening machine can be improved.

Description

Swinging cross roll tilt adjustable bar straightening mechanism

Technical field

The utility model relates to a kind of swinging steel bar straightener, and this straightening mechanism can be used for the bar straightening of different-diameter and different materials.

Background technology

High speed development along with building industry, the straightening technology of armature wire is also updated, but the swinging steel bar straightener of domestic production for the aligning different-diameter reinforcing bar the time effect not very good, this mainly is because a kind of straightener of model can well be aligned the reinforcing bar of special diameter, but after having changed the reinforcing bar of different-diameter, great changes have taken place in the contact area of reinforcing bar and cross roll and lead of screw parameters such as (distances that roundwood advances when circling), if do not take some measures will not cause straightening quality descend, even can cause spiral curved and scrap.

Summary of the invention

In order to overcome existing swinging steel bar straightener above shortcomings, the utility model provides a kind of swinging cross roll tilt adjustable bar straightening mechanism, the utility model is adjusted the contact area and the lead of screw of reinforcing bar and cross roll by the inclination angle of adjusting cross roll and reinforcing bar axis, make a straightener can better be applicable to the bar straightening of different-diameter, easy to operate, improved straightening quality and efficient.

The technical scheme that its technical problem that solves the utility model adopts is: cross roll 4 is installed on the roll shaft 10 by bearing, roll shaft 10 is fixed on the mill pinion frame 3 that profile of tooth is installed, the quantity of mill pinion frame 3 is 3-7, in the mill pinion frame 3 positive and negative alternate holes that are installed in combined type aligning tube, can in the hole, rotate, adjust in tooth bar 8 and the whole tooth bar 14 of minor be fixed on the band chute by fastening bolt 9 the chute of side's pillow 7 with gears engaged on the mill pinion frame 3 long, fastening bolt 9 is unclamped, the whole tooth bar 14 of long adjustment tooth bar 8 and minor can slide in chute, rotate in the hole of straightening drum thereby drive with its meshed gears roller frame 3, to realize that collective adjusts the inclination angle of cross roll 4, angle adjustment back is well tightened locking to bolt 13.

In Fig. 1, Fig. 2 and Fig. 3,1. minor axis head, 2. side's pillow, 3. mill pinion frame, 4. cross roll is 5. depressed the adjustment nut, 6. the major axis head 7. is with the side of chute to rest the head on, 8. long tooth bar, 9. fastening bolt, the 10. roll shaft adjusted, 11. wheel carrier, 12. adjust screw rod, 13. bolts, and 14. minors are put in order tooth bar, 15. gear teeth.

The specific embodiment

Fig. 1 is the disclosed embodiment (see figure 1) of the utility model, in 5 mill pinion frame 3 forward and reverse alternate holes that are installed in the combined type aligning tube that is made of the side's pillow 7 by minor axis head 1, side's pillow 2, major axis head 6, band chute, cross roll 4 is installed on the roll shaft 10 of mill pinion frame 3.Mill pinion frame 3 is a sub-assembly, be processed with the gear teeth 15 on its wheel carrier 11 and adjust screw rod 12, in the long chute of adjusting tooth bar 8 and whole tooth bar 14 usefulness fastening bolts 9 sides of being installed in of minor pillow 7 and with the gear teeth 15 engagements of mill pinion frame 3, the inclination angle of all cross rolls 4 can be put in order tooth bar 14 by long adjustment tooth bar 8 and minor and adjust.One end of mill pinion frame 3 is depressed and is adjusted nut 5, and the radial position of mill pinion frame 3 is adjusted nut 5 adjustment and fixing with bolt 13 separately by depressing.

Reinforcing bar is sent to continuously along aligning tube axis, depresses and adjusts nut 5 adjustment drafts separately.Adjust the long position of adjusting tooth bar 8 and the whole tooth bar 14 of minor, make cross roll 4 suitable with the angle of reinforcing bar axis.The long adjustment on tooth bar 8 and whole tooth bar 14 chutes of minor has scale, can be transferred to corresponding scale according to the difference of accent bar diameter, thereby reach best leveling effect.
