Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments.
Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-4, an adjustable arc die of a bending machine comprises an upper die 1 and a round bar 2 detachably mounted at the bottom of the upper die 1, wherein the lower part of the upper die 1 is provided with a plurality of mounting notches 11 with downward openings, a backing plate 3 is arranged in each mounting notch 11, and the round bar 2 is connected with the backing plate 3 through a bolt 4.
When a workpiece is bent, the upper die 1 needs to be matched with the lower die, the upper die 1 needs to be installed on the bending machine, and for the convenience of installing the upper die 1, the upper die 1 comprises an upper die body 12, an installation part 13 located above the upper die body 12, and a connecting part 14 located below the upper die body 12.
Specifically, the upper die 1 is connected to the bending machine through an upper mounting portion 13, and is matched with the round bar 2 through a lower connecting portion 14.
In order to increase the stability of the connection of the upper die 1 to the round bar 2, the mounting notches 11 are evenly distributed on the connecting portion 14.
In order to fix backing plate 3 in installation notch 11, prevent that it from droing from installation notch 11 to guarantee the stability of being connected between backing plate 3 and the pole 2, install two lugs 15 that set up in opposite directions on the both sides inner wall of installation notch 11, backing plate 3 installs in installation notch 11 and is located the top of lug 15.
Specifically, the width of the backing plate 3 is greater than the spacing distance between the two projections 15 and less than the width of the mounting slot 11.
The arrangement of the spacing distance between the two projections 15 prevents the shim plate 3 from falling out of the mounting slot 11, and the width between the shim plate 3 and the mounting slot 11 is selected to facilitate the placement of the shim plate 3 in the mounting slot 11.
