Working principle:
The bending and forming method of the double-dovetail-groove special-shaped tube comprises the following steps:
step one: installing and adjusting the device, and setting an initial state;
specifically, according to the bending forming process of the double-dovetail-groove special pipe, a lower die roller 21, an upper die roller 22 and a roller 25 are selected, so that central axes of the lower die roller 21 and the upper die roller 22 are in the same straight line, the lower die roller 21 and the upper die roller 22 on the last group of frames 2 are arranged to be cylindrical, and the roller 25 is cylindrical, so that special straightening equipment is reduced, and the equipment utilization rate is improved;
step two: placing the plate into a feeding port of the device, starting a first motor 9, and bending and forming;
Specifically, the first motor 9 is started to drive the lower rotating shaft 5 to rotate, the lower rotating shaft 5 drives the lower gear 10 and the lower die roller 21 to rotate, the lower gear 10 drives the upper gear 11 to rotate, the upper gear 11 drives the upper rotating shaft 7 to rotate, the upper rotating shaft 7 drives the upper die roller 22 to rotate, the plate passes through between the lower die roller 21 and the upper die roller 22, and can be conveyed by the lower die roller 21 and the upper die roller 22 which rotate while being bent, and the plate finally forms the main contour of the double-dovetail-groove special pipe under the bending action of a plurality of groups of lower die rollers 21, upper die rollers 22 and rollers 25;
Step three: the scanner 30 scans the surface and the profile of the plate after each bending, and the adjusting system adjusts the spacing between the lower die roller 21 and the upper die roller 22 of the next group according to the surface and the profile of the plate, and the spacing between the roller 25 and the lower die roller 21 and the upper die roller 22;
specifically, the method comprises the following steps:
Step three- (one): the scanner 30 scans the surface and contour of the plate after each bending and transmits the surface and contour to the identification module;
Step three- (two): the recognition module recognizes abnormal surface conditions and outline conditions of the plate during bending, and the abnormal surface conditions comprise pits, bulges and outline deformation bending position and azimuth marks;
Specifically, when the recognition module recognizes the surface of the plate, the recognition module judges as a bulge or a pit according to the change of the surface color of the plate during the conveying of the plate, and after each bending, the recognition module judges whether bending deformation exists or not according to the set standard and the deviation between the actual profile and the set profile and marks the outline;
Step three- (three): the calculation module calculates the time T required from the abnormal position of the surface and the bending position of the profile deformation to the bending of the next group of lower die roller 21, upper die roller 22 and roller 25;
Specifically: since the output end of the first motor 9 is fixedly connected with the lower rotating shaft 5, the lower die roller 21 is in key connection with the lower rotating shaft 5, and the plate is conveyed by the lower die roller 21 and the upper die roller 22 which rotate during bending, the advancing speed of the plate is related to the radius of the lower die roller 21 and the rotating speed of the first motor 9 during bending, so the advancing speed V of the plate is as follows: wherein: r is the rotation speed (unit: revolutions per minute) of the first motor 9, and R is the radius (unit: meters) of the lower die cylinder 21;
Since the distance between two adjacent sets of frames 2 is fixed, the scanner 30 is fixedly connected to the fixed frame 29, and the fixed frame 29 is fixed to the side of the frame 2, the time T required for identifying the surface abnormality to reach one set of lower die roller 21 and upper die roller 22 is related to the distance between two adjacent sets of frames 2 and the distance between the same set of frames 2 and the scanner 30, so the time T required is: the method comprises the following steps:
Wherein: h is the distance (in meters) between two adjacent sets of racks 2, H is the distance (in meters) between the same set of racks 2 and the scanner 30;
Step three- (four): after the lower die roller 21, the upper die roller 22 and the roller 25 of the next group are bent for the time T normally, the control module controls the corresponding second motor 26 and the electric telescopic rod 27 on the frame 2 of the next group, and adjusts the interval between the lower die roller 21 and the upper die roller 22 and the interval between the roller 25 and the lower die roller 21 and the upper die roller 22;
Specifically, when the code scanner located above or below the plate scans out abnormal surface or abnormal profile, and the identification module performs marking, the identification module feeds back to the control module, the control module controls the second motor 26 to start forward rotation to drive the transmission shaft 17 to forward rotate, the transmission shaft 17 drives the transmission helical gear 18 to forward rotate, the lead screw 15 is driven to forward rotate, the connecting block 12 is enabled to move downwards, the upper bearing seat 6 is driven to move downwards, the distance between the upper bearing seat 6 and the lower bearing seat 4 is reduced, otherwise, the second motor 26 is started to reverse rotation to drive the transmission shaft 17 to reverse rotation, the distance between the upper bearing seat 6 and the lower bearing seat 4 can be increased, and the distance between the lower die roller 21 and the upper die roller 22 is finely adjusted;
When the scanner 30 positioned on the left side or the right side of the plate scans out the indication of abnormality, and the identification module carries out marking, the identification module feeds back to the control module, the control module controls the electric telescopic rod 27 on the corresponding side to extend and drives the connecting plate 28 to move towards the lower die roller 21 and the upper die roller 22 and drive the roller 25 to move towards the lower die roller 21 and the upper die roller 22, so that the distance between the roller 25 and the edge of the lower die roller 21 and the edge of the upper die roller 22 is reduced, the profile of the bent plate can be inwards retracted, the profile deviation is reduced, the pressure between the roller 25 and the lower die roller 21 and the upper die roller 22 can be increased, and the abnormal condition of the plate is reduced; otherwise, the electric telescopic rod 27 is extended, so that the distance between the electric telescopic rod and the edge parts of the lower die roller 21 and the upper die roller 22 can be increased, bending is normally performed, the profile is enlarged, inward contraction of the profile is avoided, and the profile is prevented from becoming large, so that when the electric telescopic rod is bent next time, the electric telescopic rod can be used for strengthening and straightening the previous bending, the deformation of the surface and the profile of the whole plate during bending is reduced, the bending effect and precision are improved, and the bending work efficiency is improved.
Step three- (fifth): after the next set of lower die roller 21, upper die roller 22 and roller 25 all pass through the surface and contour anomaly positions, the initial state is restored.
It should be added that if the lower die roller 21, the upper die roller 22 and the roller 25 on the next group of machine frames 2 cannot adjust the surface and the profile of the bent plate, the next group can continuously adjust the plate, and the third step is repeated;
step four: and after the bending and straightening are completed, welding joint, polishing a welding line, cutting segments, polishing a cutting surface, marking, cooling and detecting the flaw.
Through the steps, the steel plate can be continuously output, flanging and bending can be carried out for a plurality of times, the double-dovetail-groove special pipe with the required shape can be produced, the precision of the special pipe is ensured, and the production efficiency of the special pipe is improved.
