Abstract
The utility model discloses an kinds of proof warp crooked sheet metal component, the punching press is formed with the bulge on the sheet metal component, the slot-like material line that ends is seted up to the adjacent department of bulge, end the material line edge the circumference of bulge extends, just end the material line loop in the bulge among the above-mentioned sheet metal component, during punching press the bulge on the sheet metal component, can be simultaneously at the adjacent department punching press slot of bulge, and then form the material line that ends, because end the material line loop in the bulge to reduce or eliminate the stress between bulge and the sheet metal component main part, after sheet metal component stamping forming, its whole roughness is better, and proof warp the bending performance is better.
Description
Technical Field
The utility model relates to a sheet metal work piece with boss or bulge especially relates to kinds of proof warp crooked sheet metal work pieces.
Background
In the process of forming the sheet metal workpiece, please refer to fig. 1 and 2, many times, a boss 8 with a concave side and a convex side needs to be stamped on the sheet metal workpiece 7, after the stamping is completed, since the sheet metal workpiece 7 deforms, -defined stress is formed between the boss 8 and the main body of the sheet metal workpiece 7, and the stress will cause the sheet metal workpiece 7 to generate a warping shape as shown in fig. 1, so that the requirement of flatness is difficult to meet.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model lies in, to prior art not enough, provide kinds and prevent to take place warping panel beating work piece through addding only stockline.
In order to solve the technical problem, the utility model adopts the following technical scheme.
kinds of proof warp metal plate work piece, the last punching press of metal plate work piece is formed with the bulge, the material line is ended to the slot-like has been seted up to the adjacent department of bulge, end the material line edge the circumference of bulge extends, just end the material line encircle in the bulge.
Preferably, a gap exists between the stopper line and an edge of the projection.
Preferably, the width of the stock removing line is 3mm, and the depth of the stock removing line is 0.3 mm.
The utility model discloses an among the proof warp crooked sheet metal component, when punching press the bulge on the sheet metal component, can be simultaneously in the adjacent department punching press slot of bulge, and then form ending the material line, because end the material line loop around in the bulge to reduce or eliminate the stress between bulge and the sheet metal component main part, after sheet metal component stamping forming, its whole roughness is better, and proof warp the bending property better.
Drawings
FIG. 1 is a structural diagram of a conventional sheet metal workpiece;
FIG. 2 is an enlarged view of portion A of FIG. 1;
FIG. 3 is a structural diagram of the sheet metal workpiece of the present invention;
fig. 4 is an enlarged view of a portion B in fig. 3.
Detailed Description
The present invention will be described in more detail with reference to the accompanying drawings and examples.
The utility model discloses an kinds of proof warp bent sheet metal component, it is shown with fig. 4 to combine, the punching press is formed with bulge 2 on the sheet metal component 1, narrow slot form end stockline 3 is seted up to bulge 2's adjacent department, end stockline 3 follows bulge 2's circumference is extended, just end stockline 3 encircle in bulge 2.
Among the above-mentioned sheet metal work piece, when punching press bulge 2 on sheet metal work piece 1, can be simultaneously at bulge 2's adjacent department punching press slot, and then form ending material line 3, because ending material line 3 encircle in bulge 2 to reduce or eliminate the stress between bulge 2 and the 1 main part of sheet metal work piece, after 1 stamping forming of sheet metal work piece, its whole roughness is better, and it is better to prevent warping the performance.
In order to further to improve the buckling resistance, in the embodiment, a gap 4 exists between the stop line 3 and the edge of the convex part 2, and under the combined action of the gap 4 and the stop line 3, the stress between the convex part 2 and the main body part of the sheet metal workpiece 1 is further relieved or eliminated.
As preferred modes, multiple experiments show that the width of the stock stopping line 3 is 3mm, the depth of the stock stopping line 3 is 0.3mm, the stock stopping line 3 with the width and the depth can better play a role in preventing warping, and meanwhile, the overall strength of the sheet metal workpiece 1 cannot be influenced.
The above is only the embodiment of the present invention, and is not intended to limit the present invention, and all modifications, equivalent replacements or improvements made within the technical scope of the present invention should be included within the protection scope of the present invention.
Claims (3)
- The utility model provides an kinds of proof warp metal plate work piece, its characterized in that, the punching press is formed with bulge (2) on metal plate work piece (1), narrow-slot form end stockline (3) have been seted up to the adjacent department of bulge (2), end stockline (3) are followed the circumference of bulge (2) extends, just end stockline (3) encircle in bulge (2).
