Abstract
The invention relates to raw steel material production class, in particular to a method for processing a C-shaped bend arc purline. The method comprises the following steps: 1. band steel decoiling; 2. leveling; and 3. cutting. The method is characterized by further comprising rolling and bending. The rolling molding and bending of the steel sheet is realized by a rolling and bending molding machine, the steel sheet is rolled for molding by at least three pairs of molding roller assemblies in the rolling and bending molding machine; and the axial direction position and the horizontal angle among the molding roller assemblies are regulated to cause the steel sheet to bend during rolling molding so as to form a C-shaped bend arc purline. The invention has the advantages that the simultaneous realization of bending and molding solves the technical problem of difficult arc control for the C-shaped purline, reduces the number of production site and equipment, and lowers the cost.
Description
Technical field
The present invention relates to steel production class, particularly relate to a kind of method that is used for machining C-shaped curved arc purlin.
Background technology
Building field often requires to adopt the steel purlin bar to support peripheral structure, as is used to build roofing or metope.What adopted usually all is the steel purlin bar of thin wall type, the normal model that adopts has square tube, rectangular tube, pipe, C type and Z type purlin, thereby clod wash arc forming technique is to utilize metal material progressively to produce the cross sectional shape that plastic deformation draws setting under the effect of continuous mechanical external force.In the prior art, clod wash arc former usually is fit to the machine-shaping to square tube, rectangular tube and pipe, and C type purlin curved arc is because discontinuity, and is difficult to realize controlled curved arc moulding.Often require to adopt the curved arc purlin to look for shape to the abnormal curved surface architectural design, if adopt the purlin of above-mentioned bendable arc shape, main structure has been increased the load deadweight, and purlin connects the structure that needs relative complex, it is unfavorable to produce structure stress, improve thereby expense is also just corresponding from economic angle, complicated simultaneously structure is to all increasing difficulty accordingly in factory process and site operation.
Summary of the invention
The objective of the invention is provides a kind of method that is used for machining C-shaped curved arc purlin according to above-mentioned the deficiencies in the prior art part, and this method utilizes curved arc and moulding to realize simultaneously, has solved the controlled curved arc difficult technologies of C type purlin problem.
Realization of the present invention is finished by following technical scheme:
A kind of method that is used for machining C-shaped curved arc purlin said method comprising the steps of:
1. band steel uncoiling;
2. smoothing;
3. cutting cutting,
It is characterized in that this method also comprises roll extrusion, curved arc, the roll forming of described steel plate and curved arc realize that by roll extrusion curved arc make-up machine described steel plate is by at least three pairs of format roll assemblies roll forming in the described roll extrusion curved arc make-up machine; And, make steel plate curved arc in roll forming become C type curved arc purlin by adjusting axial location and the level angle between the described format roll assembly.
The quantity of described format roll assembly is 5 pairs.
The radian that described 5 pairs of format roll assemblies are constituted is the radian of C type curved arc purlin.
A kind of device of realizing roll extrusion in the said method, curved arc step, comprise back and front supporting plate and frame, described back and front supporting plate is arranged at the frame both sides respectively, it is characterized in that this device also comprises some adjustable connection platforms and format roll assembly, described format roll assembly is located on the adjustable connection platform, and moves axially along adjustable connection platform; Described adjustable connection platform one end is articulated on the rear bearing sheet, and the other end and front end panel are bolted to connection, and adjusts the angle of described format roll assembly by the fixing point of regulating adjustable connection platform and front end panel.
Described format roll assembly is 5 with the adjustable quantity that is connected platform.
Advantage of the present invention is: utilize curved arc and moulding to realize simultaneously, solved the controlled curved arc difficult technologies of C type purlin problem; C type purlin curved arc and moulding realize simultaneously, reduce production site and production equipment, have reduced cost.
Description of drawings
Accompanying drawing 1 is an embodiment of the invention principle schematic.
The specific embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technical staff's of the same trade understanding:
As shown in Figure 1, label 1-3 represents respectively: C type curved arc purlin 1, format roll assembly 2, front end panel 3, rear bearing sheet 4, adjustable connection platform 5, roll extrusion bender 6.
At first choose the band steel of appropriate size, and adopt uncoiler and levelling machine will be processed into the steel plate of level with steel.According to span, radian and the width of required C type curved arc purlin 1, decide the size of cutting steel plate then, adopt cutting machine that steel plate is cut into required specification then; Afterwards steel plate is put into the tail end of roll extrusion bender 6, utilized 5 pairs of format roll assemblies 2 that are provided with in the roll extrusion bender 6 that steel plate is processed into C type curved arc purlin 1.
As shown in Figure 1, roll extrusion bender 6 comprises front end panel 3, rear bearing sheet 4 and frame (not shown).Front end panel 3 and rear bearing sheet 4 are arranged at the frame both sides respectively, be provided with adjustable connection platform 5 between front end panel 3 and the rear bearing sheet 4, one end of adjustable connection platform 5 by bearing hinge joint on rear bearing sheet 4, the other end and front end panel 3 are bolted to connection, and can adjust the adjustable level angle that is connected platform 5 by regulating adjustable connection platform 5 with the fixing point of front end panel 3.Adjustable connection platform 5 is provided with format roll assembly 2, and format roll assembly 2 moves axially along adjustable connection platform 5.Format roll assembly 2 connects driving by chain in motor, can adapt to the format roll assembly 2 of diverse location and angle by the length of regulating chain.Be adjusted to the position of respectively rolling in the forming roll assembly 2 simultaneously promptly applicable to the C type curved arc purlin 1 of producing different rules, this knows technology for those skilled in the art, repeats no more herein.
Structure in conjunction with above-mentioned roll extrusion bender 6, the operation principle of present embodiment is as follows: by calculating the radian of C type curved arc purlin 1 to be produced, be adjusted to the axial location and the level angle of forming roll assembly 2, after the radian that 5 format roll assemblies 2 are constituted is adjusted to radian coupling with C type curved arc purlin 1, the steel plate of appropriate size size is put into the tail end of roll extrusion bender 6, in roll forming, be squeezed into curved arc, thereby generate the C type curved arc purlin 1 of controlled curved arc.
