Abstract

The invention discloses a die for bending a switch butterfly elastic piece. The die comprises an upper die and a lower die which corresponds to the upper die, wherein a first bending chamber, a second bending chamber and a third bending chamber are arranged between the first upper die and the lower die; the first bending chamber, the second bending chamber and the third bending chamber are sequentially arranged; the first bending chamber is used for bending a product 90 degrees; the second bending chamber is used for bending the product which is bent by the first bending chamber an obtuse angle; and the third bending chamber is used for bending the product which is bent by the second bending chamber 180 degrees. The die has the advantages that modes of straight-angle bending, obtuse-angle bending and 180-degree bending are adopted, so that the bending procedure is simple; and due to the bending bosses with cylindrical surfaces, bending assisting force is reduced, and the quality of the elastic piece is guaranteed.

Description

A kind of switch is folded shape shell fragment Bending Mould
Technical field
The present invention relates to a kind of mould, relate in particular to the folded shape shell fragment Bending Mould of a kind of switch.
Background technology
Technology of die manufacturing is the basis of modernized mould industry development; Have moulding fast, can realize batch machining; Machining accuracy is guaranteed, and wherein diel is meant in cold stamping processing, metal or nonmetallic materials is processed into a kind of special process equipment of part.Punching press is at room temperature, utilizes the mould that is installed on the forcing press that material is exerted pressure, and makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.And Bending Mould is to be used for the instrument of processing and forming plate; This instrument has various parts to constitute; Different dies is made up of different parts; It mainly realizes the processing of article profile through the change of institute's moulding material physical state, in order under the effect of bender pressure, blank is become the instrument of the product of given shape and size is arranged.
In the folded shape shell fragment process of switch; 180 ° the bending that how to guarantee shell fragment is one of difficult point, and existing is through adopting traditional slide block oblique angle head to realize, having shell fragment bending inaccuracy like this; Weak effect has increased the power-assisted in the bending process, produces waste.
Summary of the invention
Technical problem to be solved by this invention provides the folded shape shell fragment Bending Mould of a kind of shell fragment bending switch accurate, that reduce the power-assisted in the bending process.
To achieve these goals; The invention provides the folded shape shell fragment Bending Mould of a kind of switch; Comprise patrix and the counterdie corresponding with patrix; Also be provided with between first bending between the said upper die and lower die, between second bending and between the 3rd bending, between said first bending, be arranged in order between second bending and between the 3rd bending, being used for the product bending between said first bending is 90 ° of angles; Being used for through the product bending at an angle of 90 of bending between first bending between said second bending is an obtuse angle, is used between said the 3rd bending being 180 ° of angles through the obtuse-angulate product bending of bending between second bending.
Above-mentioned switch is folded shape shell fragment Bending Mould, and is preferred, comprises first upper protruding block and first lower protruding block between said first bending, and said first upper protruding block surface is the face of cylinder.
Above-mentioned switch is folded shape shell fragment Bending Mould; Preferably, comprise second upper protruding block, second lower protruding block and oblique projection between said second bending, said second lower protruding block is positioned at the second upper protruding block downside with oblique projection; Said oblique projection is positioned at second lower protruding block, one side, and said oblique lug surface is the face of cylinder.
Above-mentioned switch is folded shape shell fragment Bending Mould, and is preferred, comprises the 3rd upper protruding block and the 3rd lower protruding block between said the 3rd bending, and said the 3rd upper protruding block lower surface and the 3rd lower protruding block upper surface are parallel to each other.
Technique effect of the present invention is: the folding shell fragment of this switch at first adopts right angle bending, obtuse angle bending then, and last 180 ° of bendings make that the bending operation is simple, and adopts the bending projection on the face of cylinder to reduce the bending power-assisted, has guaranteed the quality of shell fragment.

The specific embodiment
Below, in conjunction with accompanying drawing the present invention is done further explanation.
As shown in Figure 1; The present invention provides a kind of switch to fold shape shell fragment Bending Mould; Comprise patrix and the counterdie corresponding with patrix; Also be provided with between first bending between the said upper die and lower die, between second bending and between the 3rd bending, between said first bending, be arranged in order between second bending and between the 3rd bending, being used for the product bending between said first bending is 90 ° of angles; Being used for through the product bending at an angle of 90 of bending between first bending between said second bending is an obtuse angle, is used between said the 3rd bending being 180 ° of angles through the obtuse-angulate product bending of bending between second bending; Comprise first upper protruding block 1 and first lower protruding block 2 between said first bending, said first upper protruding block 1 surface is the face of cylinder; Comprise second upper protruding block 3, second lower protruding block 4 and oblique projection 5 between said second bending, said second lower protruding block 4 is positioned at second upper protruding block, 4 downsides with oblique projection 5, and said oblique projection 5 is positioned at second lower protruding block, 4 one sides, and said oblique projection 5 surfaces are the face of cylinder; Comprise the 3rd upper protruding block 6 and the 3rd lower protruding block 7 between said the 3rd bending, said the 3rd upper protruding block 6 lower surfaces and the 3rd lower protruding block 7 upper surfaces are parallel to each other.
The folded shape shell fragment Bending Mould of this switch is in 180 ° of bending processes; Be one 90 ° of angles with the bending of shell fragment bending part at first through first upper protruding block 1 between first bending and first lower protruding block 2; And first upper protruding block 1 adopts the surface to adopt the face of cylinder, has reduced the bending power-assisted; Adopt then second upper protruding block 3 between second bending, second lower protruding block 4 and tiltedly projection 5 with above-mentioned bending product bending part at an angle of 90 once more bending be obtuse angle (greater than 90 ° angle); Wherein, Second upper protruding block 3 is used to keep other positions beyond the product bending part smooth; Accomplish bending process in obtuse angle through oblique projection 5 near second lower protruding block 4, same tiltedly projection 5 surfaces are the face of cylinder, the power-assisted in the time of can reducing bending equally; At last through the 3rd upper protruding block 6 lower surfaces that are parallel to each other between the 3rd bending and the 3rd lower protruding block 7 upper surfaces with above-mentioned obtuse angle mild be bent into one 180 ° of angles; The present invention makes the bending operation at 180 ° of angles simple through 3 steps, and adopts the bending projection on the face of cylinder to reduce the bending power-assisted, has guaranteed the quality of shell fragment.Wherein Fig. 4 is the structure chart that final switch is folded the shape shell fragment.
Though oneself discloses the present invention as above with preferred embodiment, the present invention is defined in this.Any those skilled in the art are not breaking away from the spirit and scope of the present invention, all can do various changes and modification, so protection scope of the present invention should be as the criterion with claim institute restricted portion.
