Abstract
The simple and easy section bar notching mould of the utility model, drives die shank to move downward by drive unit, die shank is moved downward together with upper bolster, owing to upper bolster offering two gathering sills, by gathering sill, upper bolster is moved downward along guided mode bar.Meanwhile, the upper mounted plate on upper bolster moves downward, and drives upper male mould to move downward, will according to workpiece slot and drift to section bar punching.For section bar punching, be provided with stripper, Surface of profile can be touched at very first time stripper, carry out compression and spacing, good supporting role is played to the tringle of upper male mould, prevents from fractureing when punching press.Moreover concave template have employed dismountable mode, can different concave templates be selected to process according to different section bars, convenient and swift, highly versatile.The mode fabircated shapes of the utility model punching, change traditional bore mode, working (machining) efficiency is higher, and the product quality of processing is higher, only needs simple processing and polishing just can reach processing request.
Description
Technical field
The utility model relates to punching, punching, cuts, stamping-out, cut-out except cutting or the mould that uses of extruding, be specifically related to a kind of simple and easy section bar notching mould.
Background technology
Blanking die is indispensable technological equipment in punching production, and good mould structure is the Reliable guarantee realizing process program.The quality of punching parts and precision height, depend primarily on quality and the precision of blanking die.Whether blanking die structure is reasonable, advanced, has a direct impact to production efficiency and the service life of blanking die itself and the safety, convenience etc. of operation.Due to blanking part shape, size, precision and production lot and working condition different, the structure type of blanking die is also different.Blanking die is mainly used in blanking and the punching of various sheet material, the working position of mould is the cutting edge of punch and matrix, withstand shocks during cutting edge work power, shearing force, bending force, and shear the strong friction power of material, thus the performance requirement to die point is mainly referred to the performance requirement of blanking die.Cold punching die can be divided into Plate-Type Blanking Dies (thickness of slab≤1.5mm) and Blanking thick plank mould (thickness of slab > 1.5mm) two kinds.For shape extrusion, particularly section bar boring, needs continuously back and forth punching, and along with the different model of section bar, relates to the replacing to mould, to increase versatility.
Utility model content
The purpose of this utility model is to provide a kind of simple and easy section bar notching mould, solves the problem that general section bar is difficult to punching, and can replace according to different model, improves applicability and working (machining) efficiency.
For achieving the above object, the technical solution of the utility model is: simple and easy section bar notching mould, comprise die shoe and upper bolster, two vertical guided mode bars are fixed with between described upper bolster and die shoe, described die shoe is provided with lower fixed station, described lower fixed station is provided with the concave template of level, and the die orifice of described concave template is upwards arranged, and described concave template offers workpiece slot; The upper end of described upper bolster is fixed with die shank, and the below of described upper bolster is fixed with upper mounted plate, and fixed plate is provided with upper male mould, and described upper male mould end is provided with drift, and the position of described drift is corresponding with the position of workpiece slot; The below of fixed plate is provided with the stripper of a level, described stripper offers the epirelief nib passed for upper male mould, is provided with back-moving spring between described stripper and upper mounted plate; Described lower fixed station is also provided with the holddown groove of level, described concave template is bolted in holddown groove.
When adopting technique scheme, drive die shank to move downward by drive unit, die shank is moved downward together with upper bolster, owing to upper bolster offering two gathering sills, by gathering sill, upper bolster is moved downward along guided mode bar.Meanwhile, the upper mounted plate on upper bolster moves downward, and drives upper male mould to move downward, will according to workpiece slot and drift to section bar punching.For section bar punching, be provided with stripper, Surface of profile can be touched at very first time stripper, carry out compression and spacing, good supporting role is played to the tringle of upper male mould, prevents from fractureing when punching press.Moreover concave template have employed dismountable mode, can different concave templates be selected to process according to different section bars, convenient and swift, highly versatile.The mode fabircated shapes of the utility model punching, change traditional bore mode, working (machining) efficiency is higher, and the product quality of processing is higher, only needs simple processing and polishing just can reach processing request.Further, adding man-hour, adopting the mode of horizontal continuity feeding, processing and positioning precision higher.
Further, be also provided with upper padding plate between fixed plate and upper bolster, fixed plate and upper padding plate are fixed on upper bolster by sunk screw.
Further, the cross sectional shape of described lower fixed station is L shape, and described concave template is fixed on die shoe by sunk screw.
Further, the workpiece slot on described concave template comprises upper and lower two horizontal groove faces, and the area of described horizontal groove face is less than the area of lower horizontal groove face.This setting can complete processing under the prerequisite of machining accuracy not affecting section bar, and facilitates the blanking of waste material.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model simple and easy section bar notching mould embodiment.
Detailed description of the invention
As shown in Figure 1, the simple and easy section bar notching mould of the utility model, comprise die shoe 1 and upper bolster 2, two vertical guided mode bars 3 are fixed with between upper bolster 2 and die shoe 1, die shoe 1 is provided with lower fixed station 4, lower fixed station 4 is provided with the concave template 5 of level, and the die orifice of concave template 5 is upwards arranged, and described concave template 5 offers workpiece slot.Workpiece slot on concave template 5 comprises upper and lower two horizontal groove faces, and the area of described horizontal groove face is less than the area of lower horizontal groove face.This setting can complete processing under the prerequisite of machining accuracy not affecting section bar, and facilitates the blanking of waste material.The upper end of described upper bolster 2 is fixed with die shank, and the below of upper bolster 2 is fixed with upper mounted plate 6, and upper mounted plate 6 is provided with upper male mould 7, and upper male mould 7 end is provided with drift, and the position of drift is corresponding with the position of workpiece slot.The below of upper mounted plate 6 is provided with the stripper 8 of a level, stripper 8 offers the epirelief nib passed for upper male mould 7, is provided with back-moving spring 9 between stripper 8 and upper mounted plate 6; Lower fixed station 4 is also provided with the holddown groove of level, concave template 5 is bolted in holddown groove.Also be provided with upper padding plate between upper mounted plate 6 and upper bolster 2, fixed plate 6 and upper padding plate are fixed on upper bolster 2 by sunk screw.The cross sectional shape of lower fixed station 4 is L shape, and described concave template 5 is fixed on die shoe 1 by sunk screw.
