Abstract
The utility model relates to a precision shearing machine for bar stock, comprising shears, a stock pressing mechanism and supporting stock. The utility model is characterized in that the shears and bar stock are not perpendicular and form definite compensation angle, and stock pressing iron of the stock pressing mechanism is oblique iron. The supporting stock is liquid column plunger type supporting material, and the cutter blade gap of the shears is bilateral circular arc shape. Because of the action of the compensation angle, the shearing deformation is reduced, the precision is enhanced, and the stock can save 2 percents. The utility model is favorable to the enhancement of the processing quality and the processing efficiency of a lower track, and is suitable for mass production and application of forging industries of bearings, automobile, gears, etc.
Description
The utility model belongs to a kind of cutter of Forging Technology.
Sheared blank is first procedure of Forging Technology, for a long time, bar shears in the production is a linear feed, cutting knife and bar vertical shear, the simultaneous metal deformation of shearing, the deformation place metal causes waste, influences shear precision, reduce the quality and the efficient of road technology down, very outstanding in production in enormous quantities.
The purpose of this utility model is to provide a kind of shear precision height.Save the precision rod cutter of material.
This precision rod cutter comprises scissors, binder, retainer, and feature is that scissors and bar out of plumb form certain offset angle, and the binder iron of feeding pressure mechanism is wedge, adopts the plunger type retainer, and the gap blade of scissors is bilateral circular arc.The movable blades of scissors is fixed on the slide block, and slide block and master cylinder link, and feeding pressure mechanism connects wedge by cylinder piston, and there is retracting spring the side, and bar becomes the compensation angle with the vertical direction of cutting knife.
The utility model adopts the horizontal hydraulic transmission, the mode that transverse movement is sheared, quilt is cut bar and the slide block upper cutter moves into certain offset angle, make to be cut and expect that the end gradient is reduced to 1～2 degree by 3～5 degree, shear precision improves, thereby can save bar 2%, also help down carrying out smoothly of road Wang Yi, improve the quality and efficient, in production in enormous quantities, have very remarkable economical technical benefits, be widely used in technical field of forging such as bearing, automobile, gear, military project.
Fig. 1 the utility model plan structure figure.
Fig. 2 gap blade structural representation.
Be described in further detail concrete structure of the present utility model below in conjunction with accompanying drawing.
Please read Fig. 1, the piston 2 of master cylinder 1 connects slide block 3, movable blades is fixed on the slide block, corresponding fixed blade 7 is contained on the body, retainer 5 adopts plunger type axle cylinder 6 to rely on the wedge 10 of pneumatic feeding pressure mechanism, prevent movable constraint, cylinder 9 control wedge reliable operations, wedge hold mode when spring 11 is assisted backhaul of producing of bar during shearing.The vertical direction of bar and scissors keeps certain offset angle.When the blade of scissors was closed, gap blade 12 was the circular arc (see figure 2).
