Description
Technical field
The utility model relates to technical field of mechanical processing, in particular to a kind of U-shaped part anti-deformation riveting die.
Background technique
With the continuous development of manufacturing technology, the requirement of manufacturing process is higher and higher, and the product of market demand is processed
Technology difficulty increases with it, and reliable and stable manufacture production product is not achieved at all with regard to existing market technique and processing technology needs
Ask, thus for manufacturing technology cross require it is very high, for hardware precision riveting technology become each manufacturing company it is unavoidable
The requirement of sophisticated product is not achieved using common riveting mode at all for difficult point, because the cooperation that riveting is interference there will necessarily be
Deformation, is unable to reach the requirement of precision.For example U-shaped part 1 shown in FIG. 1,90 ° of the outside with middle part 11 and from middle part 11 are rolled over
The curved and alar part 12 that rises, two alar parts 12 are parallel to each other.Strong loading nut 2 will by way of riveting with the middle part 11 of U-shaped part 1 into
Row interference fit, during riveting, the middle part 11 of U-shaped part 1 is just easily deformed, and this will lead to two alar parts 12 and can not protect
Parastate is held, its function can further be influenced by such problem of appearance occur.
Utility model content
The main purpose of the utility model is to provide a kind of U-shaped part anti-deformation riveting dies, can not influence to produce
Riveting problem on deformation is solved in the case where efficiency.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of U-shaped part anti-deformation riveting die, including under
Mould and upper mold, the lower die are equipped with the tray for being used to position strong loading nut, and the upper mold is equipped with the riveting plate with correcting protrusion,
Tray described in the correcting protrusion face, the lower surface of the riveting plate are horizontal plane, institute in the rest part except correcting protrusion
State tray can vertical lifting, the lower die is fixed with the pressure correcting limited block on the outside of tray, the pressure correcting limit
The top of block is plane.
Specifically, the mold is equipped with rows of riveting unit, each riveting unit all has independent tray and pressure
Correcting limited block.
Further, the mold is equipped with riveting unit in column, and each riveting unit all has independent tray and strong
Correcting limited block processed.
Further, the lower die is equipped with several limited posts for being used to guide the upper mold downlink.
By adopting the above technical scheme, the beneficial effect of technical solutions of the utility model is:
This mold can be completed at the same time two steps of riveting and correction in a clamping process, not influence production effect
In the case where rate and appearance, some important sizes is made to obtain best control.

Specific embodiment
The utility model is described in further detail combined with specific embodiments below.
Embodiment:
As shown in Figure 1 to Figure 3, a kind of U-shaped part anti-deformation riveting die of the utility model, including lower die 3 and upper mold 4,
Lower die 3 is equipped with the tray 31 for being used to position strong loading nut 2, and upper mold 4 is equipped with the riveting plate 41 with correcting protrusion 411, and correcting is convex
411 face trays 31 are played, the lower surface of riveting plate 41 is horizontal plane in the rest part except correcting protrusion 411, and tray 31 can erect
Drop is gone straight up to, lower die 3 is fixed with the pressure correcting limited block 32 positioned at 31 outside of tray, and it is flat for forcing the top of correcting limited block 32
Face.Correcting limited block 32 is forced to be used to be supported the inside of U-shaped part 1.In production, strong loading nut 2 is placed on supporting plate 31,
U-shaped 1 mouth down of part is placed on strong loading nut 2, and correcting protrusion 411 will position the installation site of strong loading nut 2, even if this
When U-shaped part 1 middle part 11 deform, the horizontal plane of riveting plate 41 and force the top of correcting limited block 32 completely after molding
It is able to cooperate and it is flattened to correction again, two steps of riveting and correction can be thus completed at the same time in a clamping process,
In the case where not influencing production efficiency and appearance, some important sizes is made to obtain best control.
As shown in Figure 3 and Figure 4, mold is equipped with rows of riveting unit, and each riveting unit all has independent tray 31
With pressure correcting limited block 32.Riveting disposable in this way can assemble multiple products, improve production efficiency.
As shown in Figure 3 and Figure 4, mold is equipped with riveting unit in column, and each riveting unit all has independent tray 31
With pressure correcting limited block 32.In this way can the disposable more products of riveting, improve production efficiency；And it similarly processes
Speed can shorten die width.
As shown in figure 3, lower die 3 is equipped with several limited posts 33 for being used to guide 4 downlink of upper mold.Limited post 33 can ensure riveting
The horizontal decline of pressing plate 41, keeps position positioning more accurate, each riveting unit is allowed to obtain the good product of appearance.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
