Description
Technical field
The utility model relates to rolling bar production equipment field, more specifically a kind of rolling fining twisted steel
The leader pass pass structure of muscle.
Background technology
Finish rolling deformed bar is widely used in highway, the large bridge of high-speed railway and slope anchorage engineering, and it has
There is connection, anchor easy, safe and reliable, easy construction.The finish rolling deformed bar that domestic market is used mainly has
Two major classes：One class is Series of High Strength, such as PSB785, PSB830, PSB930, PSB1030, is mainly used in overpass Hanging Basket
And prestressed continuous beam, specification has φ 25mm, φ 32mm etc.；Another kind of is 500MPa series, is mainly used in high ferro and wins panel
And its pedestal, appearance and size refers to GBT20065-2006, and mechanical property is performed by GB1499.2-2007, and the trade mark is HRB500
(or PSB500), main specifications has that φ 20mm are left-handed, two kinds of φ 25mm dextrorotation.Finish rolling deformed bar is the rolling on whole reinforcing bar
There are externally threaded high intensity, the straight steel bar of high-precision size, reinforcing bar requirement can be screwed on internal thread in arbitrary section
Connector or nut be attached or anchor.The major technique difficulty of production is that appearance and size required precision height, poker are steady
It is fixed, it is necessary to carry out making both sides thread horizontal bar on same helix to tooth adjustment by position phase adjusting apparatus.
Because finish rolling deformed bar needs to screw on female connector or nut in arbitrary section, therefore it closes arc
Position must not have the vertical muscle higher than base circle diameter (BCD)（That is " ears or side handles of a utensil "）, in mass production, control is got up abnormal difficult.Screw-thread steel
The leader pass pass of muscle rolling plays a part of being to do standard to make finished hole shut out qualified product during Rolling Production
Standby, general leader pass pass is using ellipse or puts down ellipse pass, as shown in figure 1, because finish rolling deformed bar horizontal bar is trapezoidal thread,
For the fixing for ensureing to connect or anchoring, it is desirable to which bodily form thread is contour, the conjunction arc position in the middle of the trapezoidal thread in both sides is easily long
Go out " ears or side handles of a utensil ", even if finished product interlude can be controlled without " ears or side handles of a utensil ", tens meters of scopes are also had end to end and there are " ears or side handles of a utensil ", it is necessary to are chosen
Take, have a strong impact on lumber recovery.
So a kind of leader pass pass structure that vertical muscle can be avoided to produce is designed, for the manufacturing enterprise of this area
With higher actual use value, it not only can preferably limit the broadening of finished hole, it is to avoid grow " ears or side handles of a utensil ", improve production
The lumber recovery of product, and operating efficiency can be further lifted, improve enterprise's productivity effect.
Utility model content
The utility model discloses a kind of leader pass pass structure for rolling finish rolling deformed bar, and its main purpose exists
In overcoming deficiencies of the prior art and shortcoming.
The technical solution adopted in the utility model is as follows：
A kind of leader pass pass structure for rolling finish rolling deformed bar, including a flat ellipse pass body, this puts down ellipse pass body
Upper/lower terminal be respectively a trench bottom, two trench bottom respectively to this put down ellipse pass body inside it is recessed, and formed a groove
Bottom concave arc, the distance that the trench bottom sets to the concave be upper and lower two trench bottom between distance 1 to eight/9th/
One.
Further, the distance that the trench bottom sets to the concave be upper and lower two trench bottom between distance eight/
One.
Further, the sidewall draft angles for putting down ellipse pass body are 45 °.
By above-mentioned to description of the present utility model, compared to the prior art, the utility model has the advantage of：
The utility model forms bottom land concave arc, and then limit finished product by the way that the trench bottom for putting down ellipse pass body is set to the concave
The broadening of pass, makes the fining twisted steel adhesion of tendon and muscle after injury arc position that rolls out also corresponding indent, it is to avoid long earing, meanwhile, make finished product
Reinforcing bar can be screwed in arbitrary section to be attached or anchors with female connector or nut.The utility model not only may be used
Preferably to limit the broadening of finished hole, it is to avoid grow " ears or side handles of a utensil ", the lumber recovery of product is improved, and can further be lifted
Production operation efficiency, improves enterprise's productivity effect.
Brief description of the drawings
Fig. 1 is the leader pass pass structure of finish rolling deformed bar in the prior art.
Fig. 2 is structural representation of the present utility model.
Embodiment
Illustrate further to illustrate embodiment of the present utility model with reference to the accompanying drawings.
A kind of leader pass pass structure for rolling finish rolling deformed bar, including a flat ellipse pass body 1, this puts down ellipse pass body
1 upper/lower terminal is respectively a trench bottom 2, and the inside that two trench bottom 2 puts down ellipse pass body 1 to this respectively is recessed, and is formed
One bottom land concave arc, the distance that the trench bottom 2 sets to the concave is 1/8th of distance between upper and lower two trench bottom 2.
Further, the sidewall draft angles for putting down ellipse pass body 1 are 45 °.
The utility model forms bottom land concave arc, and then limit finished product by the way that the trench bottom for putting down ellipse pass body is set to the concave
The broadening of pass, makes the fining twisted steel adhesion of tendon and muscle after injury arc position that rolls out also corresponding indent, it is to avoid long earing, meanwhile, make finished product
Reinforcing bar can be screwed in arbitrary section to be attached or anchors with female connector or nut.The utility model not only may be used
Preferably to limit the broadening of finished hole, it is to avoid grow " ears or side handles of a utensil ", the lumber recovery of product is improved, and can further be lifted
Production operation efficiency, improves enterprise's productivity effect.
Embodiment of the present utility model is above are only, but design concept of the present utility model is not limited merely to
This, it is every that the utility model is improved with carrying out unsubstantiality using this design, it should belong to infringement the utility model protection
The behavior of scope.
