Abstract
The present invention relates to a kind of medium-and-large-sized stamping parts blank holding device of die for quick trial production, it is characterized in that: blank holder is fixed on flanging frame by the planar section at two ends, the inner hole thread of the other both sides underrun platform of blank holder is connected with support bar, the position of platform endoporus is coaxial with press jogger hole position, support bar withstands on blank holder platform endoporus bottom surface, vertical with blank holder end flat, support bar is connected with Height Adjustment external threading, Height Adjustment cover bottom surface and flanging frame bottom surface one flat, with locking nut by Height Adjustment cover locking.Its blank holder is lightweight, and structure is simple, and cost is low, and the manufacturing cycle is short.Only need from new design and processing blank holder in different medium-and-large-sized stamping parts draw forming flange fixing installations, flanging frame need not be reprocessed, support bar can be processed into series of height, for different blank holders, only need to select the support bar of proper height to mix again manufacture that Height Adjustment cover and locking nut just complete flange fixing installation.
Description
Technical field
The present invention relates to a kind of medium-and-large-sized stamping parts blank holding device of die for quick trial production, belong to fast mould field.
Background technology
The especially medium-and-large-sized stamping parts drawing and shaping mold of small batch stamping parts is bulky, Heavy Weight, and high material consumption, the Design and manufacture cycle is long, and cost is high.Therefore the drawing and shaping mold for the medium-and-large-sized stamping parts of small batch simplifies as far as possible, under the prerequisite that can meet part quality, develop suitable fast mould as far as possible with few input, short cycle.
Fast Modular has zinc base alloy die, resin die, cast iron die and steel mould, first two mould due to intensity, hardness low, therefore be suitable for thin plate and the trial-production of the part such as relatively low inner surface part of quality requirement, the outer surface part higher for quality requirement or the larger structural member of thickness cylinder iron mould or punching block can only complete the trial-production of the small batch of part.
Summary of the invention
The object of the present invention is to provide a kind of medium-and-large-sized stamping parts blank holding device of die for quick trial production, its blank holder is lightweight, and structure is simple, and cost is low, and the manufacturing cycle is short.
Technical scheme of the present invention is achieved in that medium-and-large-sized stamping parts blank holding device of die for quick trial production, is made up of flanging frame, blank holder and support bar, Height Adjustment cover and locking nut; It is characterized in that: blank holder is fixed on flanging frame by the planar section at two ends, the inner hole thread of the other both sides underrun platform of blank holder is connected with support bar, the position of platform endoporus is coaxial with press jogger hole position, support bar withstands on blank holder platform endoporus bottom surface, vertical with blank holder end flat, support bar is connected with Height Adjustment external threading, Height Adjustment cover bottom surface and flanging frame bottom surface one flat, with locking nut by Height Adjustment cover locking.Described support bar is coaxial by two sections of thread segments, the plane perpendicular of its axis and support bar; Blank holder end flat is coplanar, and platform inner hole thread axis is vertical with end flat; Height Adjustment cover internal thread axis and its support end plane orthogonal.
Described blank holder is the flat board made of a block casting or the plate part with curve form.
Good effect of the present invention is: blank holder is lightweight, structure is simple, cost is low, manufacturing cycle is short, only from new design and need process blank holder in different medium-and-large-sized stamping parts draw forming flange fixing installations, flanging frame need not be reprocessed, and support bar can be processed into series of height, for different blank holders, only need to select the support bar of proper height to mix again manufacture that Height Adjustment cover and locking nut just complete flange fixing installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is flanging frame 1 structural representation of the present invention.
Fig. 3 is blank holder 2 structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described: as Figure 1-3, medium-and-large-sized stamping parts blank holding device of die for quick trial production, is made up of flanging frame 1, blank holder 2 and support bar 3, Height Adjustment cover 4 and locking nut 5; It is characterized in that: blank holder 2 is fixed on flanging frame 1 by the planar section at two ends, the inner hole thread of the other both sides underrun platform of blank holder 2 is connected with support bar 3, the position of platform endoporus is coaxial with press jogger hole position, support bar 3 withstands on blank holder platform endoporus bottom surface, vertical with blank holder end flat, support bar 3 and Height Adjustment are overlapped 4 and are threaded, and it is flat that Height Adjustment overlaps 4 bottom surfaces and flanging frame 1 bottom surface one, with locking nut 5 by Height Adjustment cover 4 locking.
Described support bar 3 is coaxial by two sections of thread segments, the plane perpendicular of its axis and support bar 3; Blank holder 2 end flat is coplanar, and platform inner hole thread axis is vertical with end flat; Height Adjustment overlaps 4 internal thread axis and its support end plane orthogonal.
Blank holder 2 is exactly the flat board made of a block casting or the plate part with curve form, the region that this part is connected with flanging frame 1 is plane, the region be connected with support bar 3 is platform area, screwed hole is processed in platform area, support bar 3 is linked together by screw thread and blank holder 2 and withstands on screwed hole bottom surface, realizes the vertical of support bar 3 and blank holder 2 end flat.Height Adjustment cover 4 is connected with support bar 3 by screw thread, for adjust support bar 3 and Height Adjustment overlap 4 be connected after total length.After this length adjustment to be connected on flanging frame 1 to blank holder 2, to overlap 4 bottom surfaces concordant with flanging frame 1 bottom surface for Height Adjustment.Namely the processing of flange fixing installation is completed.
Form the main working parts of mould after blank holder manufacture completes together with punch, die, backing-out punch, then mating die is configured to die set, the effect of this blank holder is identical with the effect of common blank holder, has been all effects of flanging.In drawing forming process, blank holder is existing to be pressed on die by blank, and punch is by Sheet Metals Under Tensile Stresses, and then punch backhaul, drawn component is ejected die by backing-out punch, completes a process cycles.
