The specific embodiment
As shown in Figure 1; The utility model stripper plate reels device; Comprise hydraulic system 1 and rolling system 2, described hydraulic system 1 comprises Hydraulic Station 3, stop valve 4, non-return valve 5, overflow valve 6, oil pressure gauge 7 and hydraulic jack 8; A hydraulic fluid port of Hydraulic Station 3 is communicated with through first oil circuit 9 with the hydraulic fluid port of hydraulic jack 8 rodless cavities; Another hydraulic fluid port of Hydraulic Station 3 is communicated with through second oil circuit 10 with the hydraulic fluid port of hydraulic jack 8 rod chambers, and the direction of fluid circulation is 8 rod chambers from Hydraulic Station 3 to hydraulic jack, and the 3rd oil circuit 11 1 ends that stop valve 4 is installed are connected on first oil circuit 9; The 3rd oil circuit 11 other ends are connected on second oil circuit 10; The 4th oil circuit 12 1 ends that overflow valve 6 and oil pressure gauge 7 are installed are connected on first oil circuit 9, and the 4th oil circuit 12 other ends are connected on second oil circuit 10, and the direction of fluid circulation is from second oil circuit, 10 to first oil circuits 9 in the 4th oil circuit 12; On said second oil circuit 10 non-return valve 5 is installed, described non-return valve 5 is between the tie point of the 3rd oil circuit 11, the 4th oil circuit 12 and second oil circuit 10;
Described rolling system 2; Comprise motor 13, winding drum 14, guide cylinder 15, car body 16, first travel switch 17, second travel switch 18 and track 19; Motor 13, winding drum 14 and guide cylinder 15 are installed on the car body 16 side by side, and motor 13 is connected with winding drum 14 through belt, and car body 16 belows are equipped with wheel; Wheel is positioned on the track 19, and the below of said track 19 is equipped with first travel switch 17 and second travel switch 18;
The piston rod end of said hydraulic jack 8 is connected with the support of said winding drum 14, and the tangent line at the center line of the piston rod of hydraulic jack 8, winding drum 14 and guide cylinder 15 tops all is positioned on the same horizontal plane.
Described stop valve 4 is an electromagnet cut off valve.
Described motor 13 is a variable frequency reducer motor.
Winding drum 14 is installed on the car body 16 that can walk back and forth in the utility model; The metal plate and belt that hydraulic jack 8 and needs curl in one plane; Ignore the rolling frictional resistance of car body 16 walkings; Metal plate and belt tension force equates that with the pulling force of hydraulic jack 8 as long as the pulling force of hydraulic jack 8 is constant, then metal plate and belt tension force also is constant.The utility model is promptly set up the pulling force of hydraulic jack 8 through the operating pressure of overflow valve 6 setting hydraulic oil.Regulate the rotating speed of motor 13, make rolling speed be slightly larger than the strip extruded velocity.4 of stop valves just are in cut-off state under the state that motor 13 quits work and extruder is pushing, under this state, hydraulic oil can get into hydraulic jack 8 and promote its work; Under other any conditions, electromagnet cut off valve 4 all is in conducting state, hydraulic oil can through stop valve 4 non-resistances return, avoid oil pump, valve mechanical wear and electric energy to waste.The start and stop of motor 13 are by first travel switch 17 and 18 controls of second travel switch.
The course of work of the utility model: start motor 13; The metal plate and belt extrusion modling, through twisting on the winding drum 14 after guide cylinder 15 guiding because rolling speed is greater than extrusion speed, car body 16 can slowly be walked to the right in rolling; Hydraulic oil in the hydraulic jack 8 flows out from hydraulic jack 8 rod chambers and gets into second oil circuit 10; Because stopping of the non-return valve 5 on second oil circuit 10, fluid flows into the 4th oil circuit 12 that is connected with overflow valve 6 and oil pressure gauge 7, flows into hydraulic jack 8 rodless cavities from first oil circuit 9 again; In this process, overflow valve 6 is controlled to be constant compression force with the oil pressure in the oil circuit; This moment is because motor 13 startups; Stop valve 4 is in conducting state, so first oil circuit 9 of flowing through of the hydraulic oil in the Hydraulic Station 3, again through behind the 3rd oil circuit 11 that is connected with stop valve 4; Get in second oil circuit, the 10 unresisted hydraulic return stations 3, not to hydraulic jack 8 effects.When car body 16 is walked arrival second travel switch 18 places to the right; Motor 13 quits work, stop valve 4 is closed; Hydraulic oil in the Hydraulic Station 3 flows into second oil circuit 10, gets in hydraulic jack 8 rod chambers and the 3rd oil circuit 11 through non-return valve 5, and overflow valve 6 is controlled to be constant compression force with the oil pressure in the oil circuit; The body of rod pulling car body 16 and the rolling system 2 mounted thereto of hydraulic jack 8 return left with the strip extruded velocity, keep strip tension force simultaneously; When car body 16 returned to first travel switch, 17 places, motor 13 started, stop valve 4 conductings; The utility model stripper plate reels device and moves in circles, carries out automatically according to said process, does not need manual control in the running.
