In figure: pressure roller 7, the support 8 of the combination of steel plate unreeling structure 1, steel plate 2, rolling device 3, steel plate smoothing wrinkle pressuring flat device 4, pipe crimping pipe welding mechanism 5, guide rail 6, left-right rotary screw thread.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further elaborated.
As shown in Figure 1, 2: the steel plate smoothing wrinkle pressuring flat device on spiral weld-pipe mill, the pressure roller combined by left-right rotary screw thread is configured to propping up, and the pressure roller of described left-right rotary screw thread combination is two.The pressure roller rack-mount formation steel plate smoothing wrinkle pressuring flat device of left-right rotary screw thread combination, the pressure roller of two left-right rotary screw thread combinations is arranged on two supports respectively or is arranged on same support.The pressure roller of described left-right rotary screw thread combination is provided with the heterochiral helical groove of rotation direction by roller surface and forms.Support is provided with the adjustment structure of the compression roller heights regulating the combination of left-right rotary screw thread, adjustment structure is made up of screw rod, roller seat, handwheel, screw rod is screwed in the screw that the crossbeam of described support is arranged, handwheel is fixedly connected on screw tip, screw rod lower end is articulated and connected roller seat, the two ends of the pressure roller of described left-right rotary screw thread combination are arranged on roller seat, and rotation hand wheel reaches adjustment compression roller heights.Steel plate smoothing wrinkle pressuring flat device be arranged on spiral weld-pipe mill steel plate unreeling structure, between rolling mechanism and pipe crimping pipe welding mechanism, the pressure roller of previous left-right rotary screw thread combination is close to rolling mechanism, and the pressure roller of rear left-right rotary screw thread combination is close to pipe crimping pipe welding mechanism.The pressure roller of left-right rotary screw thread combination is pressed on the steel plate that transfers out through rolling mechanism, in steel plate conveying and pressure roller rotation process, the pressure roller of left-right rotary screw thread combination and steel plate contact squeeze, axially producing the pushing force identical with the helical groove hand of spiral, helical groove carries out smoothing wrinkle pressing to steel plate.The pressure roller of left-right rotary screw thread combination has two, the steel plate transferred out through rolling mechanism is first flattened by the preliminary smoothing wrinkle of pressure roller of previous left-right rotary screw thread combination, pressure roller further smoothing wrinkle pressing on the basis that the preliminary smoothing wrinkle of pressure roller that previous left-right rotary screw thread combines flattens of rear left-right rotary screw thread combination, improves the flatness of steel plate.The column of described support is provided with guide groove, and described roller seat is arranged in the guide groove on column.
Comprise in integrated model shown in Fig. 1: steel plate unreeling structure 1, steel plate 2, rolling device 3, steel plate smoothing wrinkle pressuring flat device 4, pipe crimping pipe welding mechanism 5, guide rail 6.Steel plate unreeling structure 1, rolling device 3, steel plate smoothing wrinkle pressuring flat device 4 is fixed by welding on guide rail 6.Steel plate smoothing wrinkle pressuring flat device 4 is provided with two, a segment distance arrangement of being separated by along guide rail 6 direction.
Fig. 2 is the structural representation (pressure roller of two left-right rotary screw thread combinations is arranged on two supports respectively) of steel plate smoothing wrinkle pressuring flat device 4, the pressure roller 7 combined by left-right rotary screw thread, support 8 form, support 8 is welded on guide rail 6, the pressure roller 7 of left-right rotary screw thread combination can be moved up and down by the adjustment structure on support, to adjust the spacing of pressure roller relative to plane on steel plate 2 of left-right rotary screw thread combination, while certain thrust is provided, play the effect that smoothing wrinkle flattens.
Application process of the present invention illustrates:
First by steel plate unreeling structure 1, rolling device 3, steel plate smoothing wrinkle pressuring flat device 4(support is installed the pressure roller of a left-right rotary screw thread combination) be fixed on guide rail 6, usually use welding manner, also can be joined with bolts.Steel plate unreeling structure 1, rolling device 3 is all provided with dynamical system, to make steel plate 2 can advance along guide rail 6 under the effect of driving force, is from left to right from figure.After steel plate 2 exports from rolling device 3, by first steel plate smoothing wrinkle pressuring flat device 4, the pressure roller 7 left-right rotary screw thread being combined by the adjustment structure on trimming rack 8 is pressed on steel plate 2, pressure roller 7 due to the combination of left-right rotary screw thread has the helical groove of the contrary rotation direction in left and right, if there is buckling phenomena when advancing in steel plate 2, the position of fold is regardless of the Left or right at steel plate direct of travel, and on the pressure roller 7 that all can be combined by left-right rotary screw thread, the push effect of helical groove makes fold become smooth.And steel plate 2 is now again when second steel plate smoothing wrinkle pressuring flat device 4, obtain smoothing wrinkle further and flatten, the flatness of steel plate 2 is further enhanced.Steel plate 2 through steel plate smoothing wrinkle pressuring flat device 4 enters pipe crimping pipe welding mechanism 5, and the qualification rate of the product processed is greatly enhanced, and also ensure that production efficiency.
