Abstract

The invention provides a method for using punch technique to process the plate into wall-thickened work-piece. Via pre-molding the plate of work-piece into protruded shape, the differential volume is equal to the protruded part; using concave and protruding moulds to punch and shorten diameter of protruding part to make the height of work-piece equal to the pre-molded height; using one group of concave moulds whose diameters are constant-height continuous arranged to punch the outer diameter of protruding part and shorten the diameter of protruding part, therefore, the outer diameter of protruding part is the diameter of protruding cylinder of final product; using composite mould with expanding diameter and molding functions to make the diameter to the inner diameter of cylinder and compressing molding to reach the height of final product to attain the final product. The invention can solve the defects of present technique and integrate the plate chassis and the protruding cylinder, to confirm the strength demand of work-piece when in working, and improve service life of work-piece.

Description

Utilize Sheet Metal Forming Technology sheet material to be processed into the method for protruding barrel thickening part
Technical field
The present invention relates to a kind of metal stamping technology, especially disclose a kind of Sheet Metal Forming Technology of utilizing sheet material is processed into the method for protruding barrel thickening part, belong to metal parts technology field.
Background technology
At present, parts production and processing for some special shape, as: tabular chassis is provided with the cylindrical workpiece of projection, and under the situation of barrel thickness greater than base plate thickness, conventional method is that the tubbiness workpiece with single processing is fixed on the chassis by mechanical processing tools (technologies such as forging, welding, riveting), constitute one-piece machine member, because workpiece is to be formed by stacking by two branch body components, its connecting portion exists problem of stress concentration, be easy to fracture, affect workpiece quality, service life and intensity from root.
And utilizing the workpiece of traditional Sheet Metal Forming Technology drawing, its wall thickness dimension can only attenuation or constant substantially, can't directly process the parts of said structure.
Summary of the invention
The invention provides and utilize Sheet Metal Forming Technology that sheet material is processed into the method for protruding barrel thickening part, solved the shortcoming that exists in other processes above-mentioned parts process.
Technical solution of the present invention may further comprise the steps:
1, preformed: workpiece sheet material is pre-formed as convex shape by punching press, makes the difference volume equal bossing, the height of boss is 1.7~2.0 times of fabricated part height, and thickness remains unchanged;
2, endure shape: select the concave, convex mould for use, the gap when keeping the mould matched moulds is carried out the punching press undergauge greater than the workpiece sheet metal thickness to the part of projection, keeps the workpiece height consistent with the preform height;
3, utilize one group of diameter for decide the continue external diameter at die stamped bumps position of arrangement of height, dwindle the boss diameter, make the external diameter of its boss reach the protruding barrel mast diameter of fabricated part;
4, shaping: with the composite die of rise footpath and die mould, the footpath of rising reaches the barrel mast internal diameter, and die mould is the fabricated part height, makes fabricated part.
Good effect of the present invention is: be shaped to one when by process for stamping and forming tabular chassis and protruding barrel mast wall thickness being thickened, guaranteed the requirement of strength that workpiece uses, the service life of having improved workpiece.
Description of drawings
Fig. 1,2 is fabricated part structure chart of the present invention.
Fig. 3,4,5 process charts for the present invention's processing.
The specific embodiment
Embodiment 1
According to shown in Figure 1, fabricated part is the chassis (following measurement unit is a millimeter mm) of wall thickness 3.5mm, and the boss height is 14, boss diameter 20, boss wall thickness 4.5.The above-mentioned size parts of explained hereafter of the present invention, step is as follows:
1, preformed: workpiece sheet material is pre-formed as convex shape by punching press, makes the difference volume equal bossing, the height 26 of boss, the approximate hemisphere of diameter phi 50, thickness remains unchanged;
2, endure shape: die working diameter φ 40 oral area fillet R8, punch φ 30 high 22. ends have punching concave die φ 6.8 concurrently to fillet R7 inside, and the hole that workpiece centre is gone out is that the location of postorder and the giving of footpath of rising are established the hole.
3, used to decide the continue die major parameter arranged of height as shown in the table, and the fillet R6-R3 of oral area dwindles the boss diameter, makes the external diameter of its boss reach the protruding of fabricated part
The big end size of die working diameter ??φ35 ??φ30 ??φ26 ??φ23 ??φ20
Cone angle in the die working diameter 14 degree 14 degree 14 degree 12 degree 10 degree
Wall portion amount of swelling ??0.05 ??0.1 ??0.2 ??0.35 ??0.45
Play the barrel mast diameter;
4, shaping: with the composite die of rise footpath and die mould, workpiece is pushed down in die cavity, 8-12 ° of internal diameter 11.3 (its length equals the workpiece height) that carries out the transition to the workpiece finished product of compression punch front end bulging cone angle is thereafter the external diameter 19.6 of the protruding device operative tip of workpiece.Reach the barrel mast internal diameter, die mould is the fabricated part height.
Make fabricated part.
Embodiment 2
According to shown in Figure 2, fabricated part is the chassis (following measurement unit is a millimeter mm) of wall thickness 2.5mm, is provided with two boss, and the boss height is 15, and boss diameter 16, internal diameter are 9.2, and boss centre-to-centre spacing is 35.The above-mentioned size parts of explained hereafter of the present invention, step is as follows:
1, preformed: different with the record of general document, at first direction two punch at 45 become 90 ° therebetween with the irregular cone of workpiece sheet material by punching press preformed projection φ 30 high 25, directly wall spacing 4 at the homonymy of plate between punch and plate.This programme makes workpiece easy fracture place at first produce compression, and the material of part mended enough to make to draw does not again split.The flat shape centre-to-centre spacing of second mold, two punch is spherical by workpiece size 35 diameters 26 ends, and die diameter phi 31 oral area R6 carry out the transition to adjacent R2, and the height of boss is 27, and thickness remains unchanged;
2, shape very: select for use die diameter 28 oral area R5 to carry out the transition to adjacent R3.5, convex mould diameter 21 high 24 end R5 endoporus are punching concave die φ 4.5, the gap when keeping the mould matched moulds is even, and the part of projection is carried out punching press undergauge and punching, keeps the workpiece height.
3, used to decide the continue die major parameter arranged of height as shown in the table, and the fillet R5-2. external diameter of oral area reaches the projection bucket column diameter of fabricated part;
The big end size of die working diameter ??φ25 ??φ22.5 ??φ20 ??φ18 ??φ16
Cone angle in the die working diameter 14 degree 14 degree 14 degree 12 degree 10 degree
