The specific embodiment
Shown in Fig. 1～2; A kind of steel hot-bending bends mouth of pipe circularity calibration system that the application embodiment provides comprises hydraulic cylinder 6, the hydraulic control system 8 that has school round belting (promptly the top cap 5) and double piston-rod, the outreach and the laser TT&C system 10 on the opportunity of withdrawal that is used to control said hydraulic cylinder 6.Wherein, laser TT&C system 10 comprises laser sensor 3, laser controller 2.Laser sensor is arranged on the hydraulic cylinder 6, is used for the distance of the position at Laser Measurement sensor 3 places apart from tube wall; Said laser controller 3 is connected with said laser sensor 3, sends control instruction according to the judgement to said laser sensor 3 measuring distances to said hydraulic control system 8; Said hydraulic control system 8 is controlled said hydraulic cylinder 6 line up circularity according to said control instruction and is calibrated.
The number of laser sensor 3 is 2, and laser sensor 3 is fixed on the hydraulic cylinder 6 through a fixed support 4 respectively.Set up a school round belting (promptly the top cap 5) separately at the hydraulic cylinder two ends; Said school round belting comprises a jacking block and arc piece; Said piston rod is connected with said arc piece through said jacking block.Laser controller 3 comprises receiver module, computing module, control module and sending module.Wherein, receiver module receives the range data that laser sensor sends; Computing module calculates the real-time size of school circle path length according to said range data; Control module compares the real-time size of said school circle path length with preset cylinder scale little progress row, and when fiducial value equates, generates reverse control instruction; Sending module is sent to said hydraulic control system with said reverse control instruction.
School circle process is shown in Fig. 3-5; Hydraulic cylinder 6 is positioned at the bend pipe mouth of pipe 1 inside center, and the top cap 5 that the double piston-rod at hydraulic cylinder 6 two ends is installed is over against the minimum place of the mouth of pipe 1 path length, and double piston-rod stretches out line up 1 and pushes up expansion; Until reaching the correction size; Receive school circle hydraulic cylinder 6 double piston-rods that contract this moment immediately, and the mouth of pipe 1 resilience reaches the mouth of pipe 1 circularity dimensional requirement.
If the distance between two laser sensors 3 is L (L＞0), the distance to tube wall that their are measured is respectively L1 and L2, and the mouth of pipe 1 path length that then this side up is L+L1+L2.Before the circle of school, a preset earlier correction sized data A deposits in the laser controller 2, sends instruction and for school circle hydraulic cylinder 6 pressure is provided for hydraulic control system 8 control Hydraulic Stations 7, and double piston-rod stretches out, and 5 pairs of bend pipe mouths of pipe of top cap, 1 inwall effect beginning school is round.In the circle process of school, the sized data measurement with L1 and L2 that laser sensor 3 can be real-time is come out, and issues Laser Measuring control device 2 and calculate, and draws the real-time size of school circle path length L+L1+L2.In laser controller 2 during preset data A, laser controller 2 sends reverse instruction to hydraulic control system 8 before these data (L+L1+L2) equal school circle, thereby control Hydraulic Station 7 acts on school circle hydraulic cylinder 6, and the withdrawal of bidirectional piston bar is accomplished the school sired results and done.
After school sired results work is accomplished, can go for a stroll through rotating mechanism high-ranking officers circle hydraulic cylinder 6 and manage the rotation of the mouth of pipe 1 center, laser controller 2 can be measured 360 of the bend pipe mouth of pipe 1 in real time and spend diameter on the directions, and whether detect the mouth of pipe 1 circularity qualified.If have defectively, can repeat to repair with colonel circle process, up to standard until the mouth of pipe 1 circularity.
Do the application is done further elaboration below in conjunction with an embodiment:
The caliber of this steel fire bending pipe is 1016mm, and thickness is 28mm; School circle hydraulic cylinder 6 cylinder diameters are 140mm, and stroke is two-way each 100mm, places center in the bend pipe mouth of pipe 1; Two laser sensors 3 are selected FT50RLA-220-L8 for use; Be installed on the circle hydraulic cylinder 6 of school through fixed support 4, distance is 820mm for L, before the circle of school; Measure them and be respectively L1 and L2 is respectively 60mm to the distance of tube wall, the mouth of pipe 1 path length that then this side up is L+L1+L2=940mm.
Before the circle of school; Preset earlier correction size A=1000mm deposits in the laser controller 2; It is CP1H-XA40 that laser controller 2 is selected the PLC model for use; It sends instruction and for school circle hydraulic cylinder 6 pressure is provided for hydraulic control system 8 control Hydraulic Stations 7, and double piston-rod stretches out, 5 pairs of bend pipe mouths of pipe of top cap, 1 inwall effect beginning school circle.
In the circle process of school, the dimensional measurement with L1 and L2 that laser sensor 3 can be real-time is come out.Laser controller 2 draws the real-time size (L+L1+L2) of school circle path length in order to receive the sized data (L1, L2) and the calculating of sending from laser sensor 3.Before these data (L+L1+L2) equal school circle in laser controller 2 during preset data A=1000mm; Laser controller 2 sends reverse instruction to hydraulic control system 8; Thereby control Hydraulic Station 7 acts on school circle hydraulic cylinder 6, the withdrawal of bidirectional piston bar, and recording this direction internal diameter after the mouth of pipe resilience is 962mm; This internal diameter numerical value satisfies the circularity requirement in the error range that allows.
Go for a stroll through rotating mechanism high-ranking officers circle hydraulic cylinder 6 at last and manage the rotation of the mouth of pipe 1 center, whether the mouth of pipe 1 circularity that detects on all directions is qualified.If have defectively, can repeat to repair with colonel circle process, up to standard until the mouth of pipe 1 circularity.
It should be noted last that; The above specific embodiment is only unrestricted in order to explanation the application's technical scheme; Although with reference to instance the application is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the application's technical scheme; And not breaking away from the spirit and the scope of present techniques scheme, it all should be encompassed in the middle of the application's the claim scope.
