Description

The decompressor of automobile damper bracket

Technical field

The utility model relates to a kind of decompressor when being used for the processing automobile shock absorber support.

Background technology

Usually, for automobile damper bracket, be on press bed, to adopt the multiple operation forming mode mostly, this method operation is many, linking between the operation is often inharmonious, and the material that size instability, the accumulation of product fillet place occur is too much, and causing the product fillet is not regular fillet, fillet is less than normal or become angle clearly, with problems such as the drawing shape have big difference.Common mould is when design, inserting that die is used is not process fillet, cause the gap of fillet place mould to be far longer than the sheet metal thickness of product, material trends towards the place big toward the gap and flows when causing being shaped, cause punching press after the extruding of product fillet diminish or out-of-shape.Mould die plate insert intensity was not enough again after but Mould Machining went out fillet, die plate insert produces angle of cut limit, though the wedge angle limit suits in the die frame, but angle of cut limit can be repeated stressed when producing in batches, the meeting crimp of point limit finally causes outstanding back, sharp limit to hang the injured labour product in the component shaping process and produces burr.Similarly complicated open class flange class stamped workpieces is very common in auto parts machinery, and problem is also very outstanding always.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and the decompressor that a kind of die plate insert intensity is big, avoid causing outstanding back, sharp limit automobile damper bracket of scratch workpiece generation burr in the product shaping process is provided.

The technical scheme that provides according to the utility model, lower bolster is set on lower bolster, on lower bolster, be provided with the die mounting blocks, offer installing hole on the die mounting blocks, in installing hole, be plugged with the bullet jacking block, be respectively equipped with die plate insert and baffle plate in bullet jacking block both sides, described baffle plate top is from die mounting blocks end face projection, by die plate insert, play jacking block and baffle plate and surround the punching press cavity, the bottom that plays jacking block is connected with the bullet ejector pin, be provided with cope match-plate pattern at bullet jacking block and die plate insert upper fixed, offer the die shank hole on the cope match-plate pattern, connect die shank in the die shank hole, die shank is provided with knockout rod, the cope match-plate pattern below is connected with upper padding plate, below upper padding plate, be provided with installing plate, the fixedly connected punch that stretches out downwards on the installing plate, described punch bottom is rectangular-shaped plate body, plate body is provided with punching press for one jiao and lacks piece, the base that described punching press lacks piece is on the bottom surface of plate body, the top margin that punching press lacks piece is on the side of plate body width, the side that punching press lacks piece is on the side of both sides, bottom surface of plate body, make that the punch bottom is the staking punch of rounding off, correspondingly, the die plate insert top is rectangular-shaped plate body, is provided with the scarce piece depression of rounding off between a side of the end face of this plate body and length direction, lack the piece depression and extend to bullet jacking block end face one side edge, the width of described scarce piece depression is shunk gradually by top to bottom.

Described die plate insert end face is provided with spacing fin at the side away from baffle plate.Be provided with location-plate at die mounting blocks end face.The side of described punch bottom width is provided with the installation fin of projection, correspondingly, offers installing hole on installing plate, and the sidewall at place, installing hole bottom is provided with and the spacing preiection that fin cooperates is installed.

The utlity model has following advantage:

1, owing to insert and all process fillet in the utility model decompressor, in the product shaping process, when material flows and die and punch-nose angle touch, be formed into the end after the mould fillet play shaping operation.

2, the utility model decompressor is used for the combined shaping usefulness of automobile damper bracket, is connected the bad workpiece quality problem that causes when avoiding repeatedly being shaped.

3, the die plate insert of the utility model decompressor is side amplification thickness, and strength of concave mould is strengthened, and has prolonged die life, and die insert fillet side intensity is enough during product shaping, the possibility of having avoided the extruding of mould fillet to give prominence to back scratch workpiece.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in the figure: lower bolster 10 is set on lower bolster 11, on lower bolster 10, be provided with die mounting blocks 9, offer installing hole 90 on the die mounting blocks 9, in installing hole 90, be plugged with and play jacking block 8, be respectively equipped with die plate insert 7 and baffle plate 13 in bullet jacking block 8 both sides, described baffle plate 13 tops are from die mounting blocks 9 end face projectioies, by die plate insert 7, play jacking block 8 and surround the punching press cavity with baffle plate 13, the bottom that plays jacking block 8 is connected with and plays ejector pin 14, be provided with cope match-plate pattern 2 at bullet jacking block 8 with die plate insert 7 upper fixed, offer die shank hole 20 on the cope match-plate pattern 2, connect die shank 12 in the die shank hole 20, die shank 12 is provided with knockout rod 1, cope match-plate pattern 2 belows are connected with upper padding plate 3, below upper padding plate 3, be provided with installing plate 4, the fixedly connected punch that stretches out downwards 5 on the installing plate 4, described punch 5 bottoms are rectangular-shaped plate body, plate body is provided with punching press for one jiao and lacks piece 52, the base that described punching press lacks piece 52 is on the bottom surface of plate body, the top margin that punching press lacks piece 52 is on the side of plate body width, the side that punching press lacks piece 52 is on the side of both sides, bottom surface of plate body, make that punch 5 bottoms are the staking punch 50 of rounding off, correspondingly, die plate insert 7 tops are rectangular-shaped plate body, between a side of the end face of this plate body and length direction, be provided with the scarce piece depression 70 of rounding off, lack piece depression 70 and extend to bullet jacking block 8 end faces one side edge, the width of described scarce piece depression 70 is shunk gradually by top to bottom.
