Description
Technical field
The present invention relates to a kind of sheet material is punched out, the material pressing device of the punching and shearing machine of processing such as punching, especially relate to a kind of Multifunction punching and shearing machine material pressing device, belong to machining equipment field.
Background technology
Multi-purpose punching and shearing machine is the panel beating and sectional bar processing equipment gathering multi -function in integral whole, sheet material, square steel, round steel, angle steel, channel-section steel, I-steel can be carried out shearing, the processing such as punching, mould are cut, it is widely used in the modern mechanical manufacturing industry such as metallurgy, bridge, communication, electric power, for preventing workpiece from phenomenon that is mobile or overturning occurring in shear history, the feeding mouth in punching and shearing machine is needed to design material pressing device, workpiece pressing before shearing work, to improve shear precision, the service life extending shearing tool is it is ensured that process safety.Existing material pressing device can only in workpiece while being compressed, lead to channel-section steel be susceptible in punching offset, affect shear precision, defective products easily occurs, cause channel-section steel to waste, and existing hold down gag needs horizontally and vertically to adjust respectively, complex operation.
Content of the invention
Machining accuracy in order to overcome the shortcomings of existing punching and shearing machine hold down gag presence is low, complex operation, the invention provides a kind of Multifunction punching and shearing machine material pressing device.
The present invention is adopted the technical scheme that by reaching above-mentioned purpose: a kind of Multifunction punching and shearing machine material pressing device，Including frame (1)、Fixing bolt (2)、Double thread screw mandrel (3)、Channel-section steel (4)、Pressed slider (5)、Support (6)、Bolt (7)、Angular contact bearing (8) and bearing block (9)，The corner of described support (6) is machined with cylindrical unthreaded hole，It is fixed in frame (1) by fixing bolt (2)，It is designed with dove-tail form groove on described support (6)，The bottom of described pressed slider (5) is machined with the swallow-tail form slide block with the mating shapes of dove-tail form groove on support (6)，Pressed slider (5) is placed in the dovetail groove of support (6)，The two ends of double thread screw mandrel (3) are machined with two sections of oppositely oriented screw threads，Two pressed sliders (5) are respectively placed on two sections of screw threads of double thread screw mandrel，And be arranged on support (6) by angular contact bearing (8)，One end of double thread screw mandrel (3) is machined with 4 flat surface，Channel-section steel (4) is placed in punching and shearing machine cutting knife groove.
The length of swallow-tail form slide block on described pressed slider (5) and the equal length of the dove-tail form groove on support (6).
The thread rotary orientation of described two pressed sliders (5) is contrary.
The invention has the beneficial effects as follows:
Employ technique scheme, when punching and shearing machine carries out punching processing to channel-section steel, rotate double thread screw mandrel, two pressed sliders carry out centering clamping to channel-section steel so that channel-section steel will not produce movement from both sides, improve shear precision, easy to operate, quick, hold down gag of the present invention significantly improves work efficiency and the processing safety of punching and shearing machine in actual use, and structure is simple, easy to spread, good in economic efficiency.
