Description

The round end rolling mill of equipment such as power communication iron tower processing usefulness

Technical field

The utility model relates to the round end rolling mill that the steel Bending Processing is used.

Background technology

Round end rolling mill is a necessary tool in the steel Bending Processing.For some professional steel processing enterprises,, need to buy the large-sized numerical control hydrolic plate bender usually in order to satisfy client's multiple demand.These large-scale numerical control device prices of NC hydraulic press brake are very high, can increase production cost greatly.And for the processing enterprise that only needs some private keys purpose small part steel members are carried out the bending of certain radian, purchase expends so high equipment, not only can waste most of function of these numerical control devices, and this large-sized numerical control equipment also can be in idle state for a long time, causes great waste to enterprise.

The patent No. is that the Chinese utility model patent of ZL200620078156.2 (publication number is CN201026500Y) discloses a kind of " stainless steel leftover pieces round end rolling mill ", it comprises framework, be provided with the cylinder A and the cylinder B that is provided with at least one lower mode cavity of upper cavity, input and output material anchor clamps and driver, cylinder A is connected and axis parallel with framework with cylinder B, one of them cylinder is a drive roll, and it transmits with output shaft and is connected; Described upper cavity and lower mode cavity are combined into a full circle, and both quantity equate and all enclose distribution along the circumferential cylinder surface continuous loop; Described charging anchor clamps with go out the front and back that material clamp is arranged on cylinder A, B, and is connected the charging folder on it mouthful and go out the feed collet mouth through gap horizontal alignment between upper and lower die cavity with framework.This round end rolling mill is compared to NC hydraulic press brake, and is simple in structure, easy to operate, but its machinable raw material has had restriction, can only be applied to that the cross section is foursquare strip stainless steel leftover pieces after opening bar, and other material is not suitable for.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of cost round end rolling mill low, that be used for the simple steel member that equipment such as power communication iron tower use is carried out Bending Processing.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the round end rolling mill of equipment such as this power communication iron tower processing usefulness, comprise framework, drive motors and be fixed on active roll on the described framework, that drive by drive motors, it is characterized in that: described active roll has two, the equal diameters of these two active rolls, its axis is positioned on the same horizontal plane and is parallel to each other; Also have an idle roll to be fixed on the described framework directly over described two active rolls.

The utility model volume is little, simple structure, cheap, easy to use, especially for convenience detach, install and transportation, the enterprise that relatively is fit to simple production working steel products member uses, and especially produces the arc fold bending of partial component, flat sheet, spill sheet material or the steel pipe of communication iron tower, electric power tower.

In order to make the utility model can carry out the bending of different radians, described idle roll can be arranged on the height adjustment mechanism, and described height adjustment mechanism is slidably disposed on the described framework.Can change the bending radian of institute's tool member by the distance between adjusting idle roll and the active roll.

Preferably, described height adjustment mechanism comprises slide plate and regulates bolt; Described framework is provided with chute, and described slide plate is slidably disposed in the described chute, and an end of regulating bolt is fixedly connected on the top of slide plate, and the other end of regulating bolt is by the spacing outside at described framework of adjusting nut.

In order to be suitable for tubulose Bending Processing just now, can be on the correspondence position on described active roll and the idle roll, be respectively arranged with the arc groove that is used for bending tubulose equipment along the circumference of roll.

As the further improvement of such scheme, the diameter of described idle roll can with the equal diameters of active roll.

Compared with prior art, the utility model the utility model volume is little, simple structure, cheap, easy to use, especially for convenience detach, install and transportation, the enterprise that relatively is fit to simple production working steel products member uses, and especially produces the arc fold bending of partial component, flat sheet, spill sheet material or the steel pipe of communication iron tower, electric power tower; The design of height adjustment mechanism can be regulated the radian of institute's tool member bending, has increased the scope of application of the present utility model.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As depicted in figs. 1 and 2, the round end rolling mill of equipment such as this power communication iron tower processing usefulness comprises framework 1, and framework 1 is formed by fixedly connecting by left and

right support

11,12 and base 13; The two ends of the

active roll

2,3 of two equal diameters axle respectively are connected on the left and right support, and the axis of these two

active rolls

2,3 is positioned on the same horizontal plane and is parallel to each other; Drive motors 7 is arranged on the outside of framework 1, and the output shaft of motor connects change gear box 8, and two output shaft (not shown)s of change gear box connect respectively and drive two

initiatively rolls

2,3.

Be positioned at two initiatively tops, center of

roll

2,3 with the isodiametric idle roll 4 of active roll, the two ends of idle roll 4 axle respectively are connected on the height adjustment mechanism 5.

Height adjustment mechanism 5 comprises two slide plates 51, is separately fixed at two adjusting bolts 52 and two locking nuts 53 of two slide plate 51 upper ends; Be respectively equipped with chute 14 on the left and

right support

11,12, slide plate 51 is slidably disposed in the chute 14; Regulate bolt for two and pass left and

right support

11,12 respectively, by locking nut 53 lockings; The perisporium of locking nut 53 is provided with convenient manually operated handle 54; The two ends of idle roll 4 axle respectively are connected on two slide plates 51.

The Bending Processing of tubulose steel for convenience, above-mentioned two initiatively on the end correspondence position of

rolls

2,3 and idle roll 4, be respectively arranged with arc groove 55 along the circumference of roll.

As shown in Figure 3 and Figure 4, when using this round end rolling mill bending sheets 6, one end of sheet material 6 is inserted from the space between active roll and the idle roll, under the drive of active roll, can in the space between another active roll and the idle roll, send through the sheet material that has certain radian after the bending.

When needs change the radian of bending, can rotate two lock nut, change and regulate bolt and be positioned at the height of support, thereby slide plate is moved in chute, change the distance between idle roll and the active roll.After this round end rolling mill Bending Processing, just can obtain different bending radians like this.

When needing bending tubulose steel, steel pipe can be placed on the arc groove place, processing method is identical.

In order to keep after sheet material, the steel pipe bending not modification, can be by progressively reducing the height of idle roll, sheet material, steel pipe repeatedly processed its radian is changed from small to big.
