Abstract

The utility model discloses a die trimming structure, which aims to solve the problem that the conventional die produces louder noise when trimming. The die trimming structure comprises an upper die and a lower die, wherein trimming inserts are connected with the upper die and the lower die and are provided with waved trimming edges; the waved trimming edges comprise a plurality of wave peaks and wave troughs which are connected sequentially and alternatively; the trimming inserts connected to the upper die correspond to the trimming inserts connected to the lower die one by one; and the wave peaks and the wave troughs of the trimming edges of the trimming inserts of the upper die are adaptive to the wave peaks and the wave troughs of the trimming edges of the trimming inserts of the lower die. According to a die, the trimming inserts are used for trimming and cutting plates by means of the trimming edges. The trimming edges are in the shape of waves, the heights of the edges are different, the cut-in depth is slowly increased when the trimming edges cut the plates, and the trimming blanking force is dispersed, so that the noise produced during cutting and trimming is reduced, the influence of cutting on the die is reduced, and the service life of die is long.

Description

A kind of die trimming structure

Technical field

The utility model relates to a kind of mould structure, more particularly, and the die trimming structure that noise was little when it related to a kind of the use.

Background technology

In the stamping parts die production stage, carry out deburring to mould, general at present employing deburring is inserted and is carried out the deburring operation, and present deburring is inserted and when carrying out deburring, can be produced bigger noise, and the die life of producing is short.

Chinese patent notification number CN201404993Y; February 17 2010 day for announcing; The name of utility model is called the integrated car Trimming Die; Comprise that automobile engine hood panel frame-type upper die and lower die install on base respectively, and flexibly connect that die shoe and counterdie are inserted and be fixedly connected is a single piece.Integral structure has reduced the workload of design and processing, has improved design efficiency, but when carrying out the deburring operation, can produce bigger noise, and the die life of producing is short.

The utility model content

The utility model has overcome existing mould can produce big noise when carrying out the deburring operation deficiency, and a kind of die trimming structure is provided, and it makes mould noise when carrying out the deburring operation little, and the die life of producing is long.

In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of die trimming structure; Comprise upper die and lower die; On upper die and lower die, be connected with deburring and insert, said deburring is inserted and is provided with corrugated trimming edge, and the waveform trimming edge comprises crest and the trough that several alternately connect successively; Be connected deburring on the upper die and lower die and insert correspondingly one by one, patrix deburring the insert trough and the crest of trimming edge of crest and trough and the counterdie deburring of trimming edge of inserting is adaptive.Mould is inserted with deburring and is carried out deburring, and deburring is inserted and cut plate through trimming edge, because the trimming edge undulate; The cutting edge height is different; Approach slowly increases in its cutting plate, realizes the dispersion of deburring blanking pressure, and the noise that in the cutting deburring, produces like this is little; And cutting is little to the influence of mould, makes the long service life of mould.

As preferably, said trimming edge is the sinusoidal waveform in two cycles.The crest of trimming edge and the number of trough are confirmed according to the mould of design; The design's trimming edge is the sinusoidal waveform in two cycles; Two crests and two troughs are just arranged, and approach slowly increases when carrying out the deburring cutting, the noise when reducing the deburring cutting.

As preferably, said deburring is inserted and is connected on the upper die and lower die with bolt.Bolt connects reliable and stable, and bolt connects and can dismantle, the maintenance replacing that makes things convenient for deburring to insert.

As preferably, said deburring is inserted, and week along upper die and lower die, each evenly was connected with 12.Deburring is inserted and evenly is connected a week of upper die and lower die, and is stressed even when deburring is cut, convenient cutting.

As preferably, said deburring is inserted and is cuboid, and trimming edge is located on the side that deburring inserts.The deburring insert structure of cuboid is simple, and design cost is low.

Compared with prior art, the beneficial effect of the utility model is: this die trimming structure makes mould noise when carrying out the deburring operation little, and the die life of producing is long.

Among the figure: 1, patrix, 2, counterdie, 3, deburring inserts, 4, trimming edge, 5, crest, 6, trough.

The specific embodiment

Pass through specific embodiment below, and combine accompanying drawing, the technical scheme of the utility model is done further to specifically describe:

Embodiment: a kind of die trimming structure (referring to accompanying drawing 1); Comprise patrix 1 and counterdie 2; On patrix 1 and counterdie 2, be connected with deburring 3 (referring to the accompanying drawings 2) of inserting with bolt; Deburring is inserted and 3 is cuboid, and deburring is inserted and 3 is provided with corrugated trimming edge 4, and trimming edge 4 is located at deburring and inserts on 3 the side.Waveform trimming edge 4 comprises that two each and every one replace the crest 5 and trough 6 that connects successively, and corrugated trimming edge 4 is the sinusoidal waveform in two cycles.Be connected patrix 1 and the deburring on the counterdie 2 and insert 3 correspondingly one by one, patrix 1 deburring the insert trough 6 of 3 trimming edges 4 of crest 5 and the trough 6 and counterdie 2 deburrings of 3 trimming edges 4 of inserting is adaptive with crest 5.Deburring insert 3 along week of patrix 1 and counterdie 2 each evenly is connected with 12.

Deburring is inserted and is connected on the upper die and lower die through bolt, when mould is carried out deburring, cuts plate through trimming edge, because trimming edge is sinusoidal; The cutting edge height is different; Approach slowly increases in its cutting plate, realizes the dispersion of deburring blanking pressure, and the noise that in the cutting deburring, produces like this is little; And cutting is little to the influence of mould, makes the long service life of mould.

Above-described embodiment is a kind of preferable scheme of the utility model, is not the utility model is done any pro forma restriction, under the prerequisite that does not exceed the technical scheme that claim puts down in writing, also has other variant and remodeling.
