Description
Technical field
The invention belongs to field of metallurgical equipment, particularly a kind of strainer that is applied in the heavy section steel pressure straightening device.
Background technology
Big shaped steel is widely used in each field of engineering construction owing to its mechanical strength height, good rigidity, and particularly large-scale H shaped steel, channel-section steel can be directly as construction timbers, as science of bridge building, workshop building etc.Heavy section steel mainly is shaped by the milling train hot rolling, and is dispatched from the factory by gag straightener shaping under cold state, aligning.Domestic present medium and small shaped steel straightening technology and equipment are ripe, but heavy section steel gag press straightening technology and equipment for straightening also belong to new technology, new equipment, because in heavy section steel gag press straightening process, increase along with shaped steel height, aligning recurvation amount and straightening force, the shaped steel bending phenomenon can occur at shaped steel and pressure head contact position, promptly compress the limit and local buckling occurs.According to analysis to the shaped steel instability Mechanism, need a kind of unsteady side pressure strainer, on its wing, set up side tension when being used for the shaped steel aligning, eliminate local buckling's phenomenon that shaped steel occurs in the gag press straightening process.
Summary of the invention
The purpose of this invention is to provide a kind of strainer that is used for the shaped steel pressure straightening device, it can eliminate local buckling's phenomenon that shaped steel occurs in the gag press straightening process.
Technical scheme of the present invention is: design a kind of strainer that is used for the shaped steel pressure straightening device, which comprises at least leading screw 6, back-moving spring 7, hydraulic cylinder 8, connect spring 4 and a pair of tensioning piece I2, tensioning piece II3; Be connected with wedge 9 under the hydraulic cylinder 8, wedge 9 is movably connected in the slit of a pair of tensioning piece I2, tensioning piece II3, and tensioning piece I2, tensioning piece II3 both sides connect by connecting spring 4; Hydraulic cylinder 8, wedge 9, a pair of tensioning piece I2, tensioning piece II3 are connected with leading screw 6 together.
Described tensioning piece I2, tensioning piece II3 slit are the isoceles triangle shape, and the angle on isosceles limit is identical with wedge 9, and cooperate with wedge 9 side slip.
Described leading screw 6 is with back-moving spring 7, and leading screw 6 is fixed on the frame 1.
Characteristics of the present invention are: this strainer that is used for the shaped steel pressure straightening device, the side direction tensile force drives wedge by oil cylinder and sets up, in the aligning process tensioning reliable and stable, tensile force is big; The tensile force size can be regulated by adjusting oil cylinder working-pressure; The position of tensioning piece can be regulated by leading screw, to adapt to the shaped steel aligning of different size.During gag press straightening, whole a kind of strainer servo-actuated that is used for the shaped steel pressure straightening device along with the distortion of shaped steel; Gag press straightening finishes, and whole a kind of strainer that is used for the shaped steel pressure straightening device automatically resets by back-moving spring, and wedge is regained by Driven by Hydraulic Cylinder, and two wedge type pieces forming the tensioning piece automatically reset by connecting spring.
Description of drawings
The invention will be further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the embodiments of the invention structural representations.
Among the figure: 1, frame; 2, tensioning piece I; 3, tensioning piece II; 4, connect spring; 5, shaped steel; 6, leading screw; 7, back-moving spring; 8, hydraulic cylinder; 9, wedge.
The specific embodiment
As shown in Figure 1, this strainer of shaped steel pressure straightening device that is used for is mainly by leading screw 6, back-moving spring 7, hydraulic cylinder 8, connection spring 4 and a pair of tensioning piece I2, tensioning piece II3; Hydraulic cylinder 8 is connected with wedge 9 by a transition piece under it, wedge 9 puts in the slit of two tensioning piece I2, tensioning piece II3, and the slit constitutes the gathering sill of wedge 9.In order to make two tensioning piece I2, tensioning piece II3 at aligning during shaped steel 5, the servo-actuated along with shaped steel 5 compressive deformations, tensioning piece I2, tensioning piece II3, hydraulic cylinder 8, wedge 9 can float along shaped steel 5 deformation directions together; Gag press straightening finishes, and whole a kind of strainer that is used for the shaped steel pressure straightening device automatically resets by back-moving spring 7, and wedge 9 is driven by hydraulic cylinder 8 and regains; Connection spring 4 connections of passing through of two tensioning piece I2, tensioning piece II3 automatically reset.The slit of two tensioning piece I2, tensioning piece II3 is the isoceles triangle shape, and is identical with wedge 9.Hydraulic cylinder 8, wedge 9 and two tensioning piece I2, tensioning piece II3 are connected by back-moving spring 7 with leading screw 6 together.Leading screw 6 handles one end is fixed on the frame 1, the other end of leading screw 6 is fixed in the connector between hydraulic cylinder 8 and the wedge 9, leading screw 6 is socketed with back-moving spring 7, tensioning piece I2, tensioning piece II3, hydraulic cylinder 8, wedge 9 are floated along shaped steel 5 deformation directions together, gag press straightening finishes, and whole a kind of strainer that is used for the shaped steel pressure straightening device automatically resets by back-moving spring 7.
Use of the present invention is: two tensioning pieces are placed between the edge of a wing of shaped steel 5, and two tensioning piece I2, the tensioning piece II3 handle by leading screw 6 is adjusted to suitable position and just in time aims between the shaped steel edge of a wing.Wedge 9 is driven by hydraulic cylinder 8 and moves up and down along its gathering sill, thereby two tensioning piece I2, tensioning piece II3 are opened to both sides respectively, sets up side tension on the shaped steel edge of a wing.When aligning shaped steel, two tensioning piece I2, tensioning piece II3 servo-actuated along with the compressive deformation of shaped steel 5.After the shaped steel aligning was finished, hydraulic cylinder 8 upwards drove wedge 9 and regains, and two tensioning piece I2, tensioning piece II3 connect 4 by spring and reset.
Parts such as leading screw 6 of the present invention, wedge 9, hydraulic cylinder 8 all are to adopt standard component or commercially available.
