Abstract
The invention relates to a novel sheet metal forming technology of a whole light truck metal half tall roof cover. The novel sheet metal forming technology includes the following steps that the unfolding size is calculated according to the overall size of the half tall roof cover, and a plate is sheared into rectangular blocks through a plate shearing machine according to the unfolding size; drawing forming is conducted on the rectangular blocks through a drawing die in a periphery positioning mode; the rectangular blocks after drawing forming are placed in a trimming and punching die, and trimming and top face hole punching are conducted in an inner shape positioning mode; the trimmed rectangular blocks are placed in a flanging, shaping and side punching die, and flanging, shaping and side punching are conducted in an inner shape positioning mode; the rectangular blocks after flanging, shaping and side punching are placed in a side flanging and side punching die, and then side flanging and side punching are conducted in an inner shape positioning mode. The whole sheet metal forming technology of the whole light truck metal half tall roof cover is achieved, and is efficient, stable in quality and capable of meeting the technical and quality requirements of products compared with a traditional welding technology.
Description
Technical field
The present invention relates to field of automobile, be specifically related to the manufacturing process of the high top of a kind of Novel light truck bulk metal half top cover.
Background technology
The general high top of light truck metal half top cover be split Welding Structure.The high top of the welded light truck metal half of split top cover existence welding mutability, the drawback that machining period is long, production efficiency is low.Need to have designed a kind of half novel high top casting coping for this reason, for realizing the punching press of entirety half high top casting coping, proposed a kind of new process, to guarantee to realize the new overall half high top casting coping of producing.
summary of the invention
The present invention, in order to overcome the deficiency of above technology, provides a kind of Sheet Metal Forming Technology that adopts the high top of stamping forming efficient Novel light truck bulk metal half top cover.
The present invention overcomes the technical scheme that its technical problem adopts:
The Sheet Metal Forming Technology of the high top of this Novel light truck bulk metal half top cover, in turn includes the following steps
A) calculate development size according to the overall size of half high top top cover, and by plate shearing machine, sheet material is cut into rectangular block material according to development size;
B) rectangular block material is located to drawing and moulding by drawing die with periphery;
C) after drawing and moulding, inserted in trimming and piercing die, with interior shape location carry out deburring, the face of rushing to summit;
D) after deburring, inserted in flange, shaping, side blow casement, carried out flange, shaping, side punching with interior shape location;
E) after flange, shaping, side punching, inserted in side flanging, side blow casement, carried out side flanging, side punching with interior shape location.
In order to reduce drawing depth, above-mentioned steps b), step c), steps d) and step e) in stamping parts relative level face tilt, itself and pressing direction formation angle theta.
In order to ensure drawing quality, above-mentioned steps is b) when drawing and moulding, and while using single action press, the pressure of press air cushion is 200-230 kilogram, and while using double action press, inner slide pressure is 200-230 kilogram.。
The invention has the beneficial effects as follows: realized the overall Sheet Metal Forming Technology of the high top of light truck bulk metal half top cover by the rush to summit step of face-flange, shaping, side punching-side flanging, side punching of blanking-drawing-deburring, with respect to traditional welding procedure, realize efficient stay-in-grade process in, met technology and the quality requirement of product.

Detailed description of the invention
Below in conjunction with accompanying drawing 1, the present invention will be further described for accompanying drawing 2.
The Sheet Metal Forming Technology of the high top of this Novel light truck bulk metal half top cover, in turn includes the following steps
A) as shown in Figure 1, first calculate development size according to the overall size of half high top top cover, and by plate shearing machine, sheet material is cut into rectangular block material 1 according to development size.B) as shown in Figure 2, rectangular block material 1 is located to drawing and moulding by drawing die with periphery.C) as shown in Figure 3, after drawing and moulding, inserted in trimming and piercing die, with interior shape positioned edge trimming line carry out deburring, the face 2 of rushing to summit.D) as shown in Figure 4, after deburring, inserted in flange, shaping, side blow casement, carried out flange, shaping, side punching punching side opening I 4 with interior shape location.E) as shown in Figure 5, after flange, shaping, side punching, inserted in side flanging, side blow casement, carried out side flanging, side punching punching side opening II 5 with interior shape location.Steps d) and step e) at twice respectively contralateral exposure I 4 side opening II 5 carry out punching, can effectively optimize the structure of mould and arrange, reduced the punching power of one-off hole-piercing.Realize the overall Sheet Metal Forming Technology of the high top of light truck bulk metal half top cover by the rush to summit step of face-flange, shaping, side punching-side flanging, side punching of blanking-drawing-deburring, with respect to traditional welding procedure, realize efficient stay-in-grade process in, met technology and the quality requirement of product.
As shown in Figure 6, step b), step c), steps d) and step e) in stamping parts relative level face tilt, itself and pressing direction P formation angle theta, by by the punching press of workpiece slant setting, can reduce drawing depth, improve ram efficiency.Because the die joint of drawing die is curved surface, because the curved surface of drawing die is arranged, from step b) die face of subsequent handling be afterwards also curved surface, just can meet design requirement.
When step b) drawing and moulding, while using single action press, the pressure of press air cushion is 200-230 kilogram, and while using double action press, inner slide pressure is 200-230 kilogram.。Pressure is less than 200 kilograms can be caused and not press tightly wrinkling phenomenon in the time of punching press drawing and moulding, in the time that air cushion pressure or inner slide pressure are greater than 230 kilograms, can cause that thrust is excessive causes that workpiece ftractures in drawing process.Thereby the air cushion pressure of forcing press or inner slide pressure are 200-230 kilogram.
