Description
Technical field
The utility model relates to the pre-bending edge forming equipment of steel pipe, more specifically, is that a kind of preparatory joggling machine leaks the step checkout gear.
Background technology
Along with the progress of material science and metallurgical technology, pipeline industry develops towards the direction of high discharge pressure with big feed flow.The requirement of strength of pipeline steel tube is increasingly high, and tube wall is more and more thicker, and diameter is increasing, has greatly promoted the development of pipeline steel tube fabrication technique.
In the steel pipe forming technique, can use the UOE operation usually, i.e. forming U shaped articles operation, O forming operation and machinery expanding operation.In the production line of UOE operation, prebending machine is used for carrying out bending operation to milling the steel plate limit portion that finishes on the limit, because all can not crimp apart from too short U type machine and the O type machine in back operation of limit portion.Pre-bending limit operation, be orbicular pipe for eliminating the socket straight section to guarantee the obtaining cross section, reduce follow-up O forming power, improve preparatory process before the moulding that edges of boards and die surface contact condition are taked in the O forming process.The parameter on pre-bending limit also has tangible influence to welding quality after the moulding of UOE steel pipe and hole enlargement quality.The principle on pre-bending limit is mould about on hydraulic press, relying on, along the steel plate length direction crooked forming method is implemented at its edge.As shown in Figure 1, be the preoperative steel plate 1 in pre-bending limit, steel plate 1 is behind crimp, and is as shown in Figure 2.As shown in Figure 3, comprise the crimp angle [alpha], the crimp height Y behind crimp length B and the pre-bending limit with the pre-bending limit relevant parameter of operation.
Yet prebending machine may appear at the leakage step phenomenon under the automatic operation mode in operating process, and general steel plate length is 12000mm, divides for three steps accomplished the pre-bending limit.But for the steel plate of 11000～114000mm and the steel plate of 12800mm～14000mm, occur leaking the step situation at overlapping or final step meeting, promptly do not accomplish the pre-bending limit, steel plate is just directly seen prebending machine off.Because UOE output bas line degree is high, rhythm of production is nervous, personnel dispose less; Operating personnel can not all carry out hand inspection to the steel plate behind each crimp; And the steel plate of seeing off behind the joggling machine arrives after next molding procedure " U " moulding; The problem of leaking the step place just can not be changed and repaired, and such consequence promptly is that the moulding of whole steel pipe can not reach requirement, thereby scraps.
The utility model content
The purpose of the utility model is to solve the leakage step problem that occurs in the operation of above-mentioned pre-bending limit, thereby provides a kind of novel preparatory joggling machine to leak the step checkout gear.
The preparatory joggling machine of the utility model leaks the step checkout gear and comprises: two bottom slide rails, at least four supports, a plurality of detecting element base, a plurality of detecting element and signal processors; Wherein said bottom slide rail is fixedly installed between two rollgangs of said preparatory joggling machine rear end abreast; Said at least four supports are installed on said two bottom slide rails equably; Said a plurality of detecting element base is separately positioned on the said support; Said a plurality of detecting element is separately positioned on the said detecting element base, and said signal processor is connected with said a plurality of detecting elements.
Preferably, said signal processor is a programmable logic chip.
Preferably, said detecting element is a grating.
Preferably, said detecting element is a travel switch.
Preferably, said signal processor further is connected with warning device.
The preparatory joggling machine of the utility model leaks the step checkout gear, loss such as reduced that steel plate is scrapped effectively.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, the composition and the operation principle of the preparatory joggling machine of the utility model being leaked the step checkout gear more specify.
As shown in Figure 4, be that the preparatory joggling machine of the utility model leaks the composition sketch map that goes on foot checkout gear.As shown in the figure; This preparatory joggling machine leaks step checkout gear and comprises: two bottom slide rails 10, at least four supports 20, a plurality of detecting element base 30, a plurality of detecting element 40 and signal processors 50; Wherein, in conjunction with Fig. 5, bottom slide rail 10 is fixedly installed between two rollgangs 4 of said preparatory joggling machine 2 rear ends abreast; And at least four supports 20 are installed on two bottom slide rails 10 equably; A plurality of detecting element bases 30 are separately positioned on the support 20, and a plurality of detecting elements 40 are separately positioned on the detecting element base 30, and signal processor 50 is connected with a plurality of detecting elements 40 through connecting lead 60.In the present embodiment, adopt four supports 20, and be equipped with a detecting element base 30 and a detecting element 40 on each support.20 liang of two places of four supports are installed on each bottom slide rail 10, and the position of support 20 can be according to the width of steel plate and the needs of actual detected, on the slide rail of bottom, move and carry out the position adjustment, also can on short transverse, adjust simultaneously.
In the present embodiment, signal processor 50 can be programmable logic chip (PLC), and it is used to receive the detection signal that detecting element 40 sends, and after detection signal carried out data, sends according to result and controls signal to follow-up warning device.Detecting element 40 can be a grating, also can be detection means such as travel switch.When detecting element 40 was grating, its installation site was lower than rollgang 4, and when detecting element was travel switch, its installation site was higher than rollgang 4.The crimp situation of 40 pairs of steel plate both sides of detecting element detects, and detection signal is transferred to signal processor 50.
As stated, signal processor 50 further is connected with warning device (figure does not show).When being judged as existence leakage step phenomenon, according to the variety classes that leaks the step phenomenon, signal processor 50 sends corresponding alarm signal to warning device.Particularly, when two detecting elements 40 of steel plate center line the same side send alarm signal through signal processor 50, can judge that there is leakage step phenomenon in a side of steel plate; When the steel plate center line not homonymy but belong to together forward or lean on after two detecting elements 40 when sending alarm signal through signal processor 50, can judge then that the steel plate both sides exist at same position leaks the step phenomenon.Alarm signal can be a light signal, voice signal or picture alarm signal etc.
As shown in Figure 5, after the pre-bending limit operation of steel plate through preparatory joggling machine 2, carry through rollgang 4; Wherein centralising device 3 is used for steel plate is carried out the centering operation, leaks the step checkout gear according to the difference in height before and after the steel plate pre-bending limit, utilizes the steel plate of 40 pairs of processes of detecting element to detect; If detect normally, then continue steel plate is transported to follow-up forming U shaped articles machine 5, if the situation of normal crimp not; Then can send Lou step alarm signal as stated; Thereby before forming U shaped articles technology, stop the conveying of steel plate, again it is carried out the operation of pre-bending limit.
In sum, the preparatory joggling machine of the utility model leaks the step checkout gear, and is simple in structure, installation, adjustment and easy to maintenance, and the leakage that can detect one-sided or bilateral same position goes on foot phenomenon.Thereby increased the quality of follow-up shaping steel tube, and loss such as reduced that steel plate is scrapped effectively.
