Description
Technical Field
The invention relates to the technical field of dies, in particular to a stamping riveting die.
Background
The stamping sheet metal part product has wide application, and two sheet metal parts with the same thickness are generally required to be stamped and riveted together in daily practical application. In the prior art, when two sheet metal parts with the same thickness are punched and riveted together, if one-time punching is carried out, the riveting of the two sheet metal parts is not firm, the two sheet metal parts are easy to drop, the rejection rate of products is high, and functional risks of the products exist; if punching is carried out after two processes of punching and pipe drawing are carried out on the sheet metal part, although the connection firmness is better than that of one-time punching, the labor intensity is high, the production efficiency is low, and the production cost is high.
Therefore, it is necessary to develop a press-riveting die to solve the above problems.
Disclosure of Invention
The present invention is directed to a stamping and riveting die, so as to solve the problems of the background art.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a punching press riveting die, includes mould and lower mould, its characterized in that: the improved die is characterized in that a hydraulic column is arranged at the upper end of the upper die, a connecting column is installed at the lower end of the upper die, a lower die cavity is arranged in the middle of the lower die, a groove is formed in one side of the lower die cavity, an electric push rod is installed inside the groove, one end of the electric push rod is fixedly connected with an extrusion plate, and a sheet metal part is arranged between the upper die and the lower die.
Preferably, the front end of the connecting column is provided with a ball groove, two sides of the inner part of the ball groove are provided with air pressure rods, and one end of each air pressure rod is provided with a ball body.
The invention has the technical effects and advantages that:
according to the invention, the riveting of two sheet metal parts can be completed through one stamping process by arranging the upper die, the lower die, the hydraulic column, the connecting column, the sheet metal part, the lower die groove, the extruding plate, the groove, the electric push rod, the ball body, the air pressure rod and the ball body groove, and the riveting firmness of the two sheet metal parts after stamping is very good, so that a stable fixing mode between two sheet materials or two products is realized, the production efficiency is greatly improved, the product cost is reduced, the processing process is reduced, the production efficiency and the product quality are improved, and the production cost is reduced.

Fig. 2 is a schematic view of the overall structure of the present invention.
Fig. 3 is a schematic view of the overall structure of the present invention.
In the figure: 1 upper die, 2 lower dies, 3 hydraulic columns, 4 connecting columns, 5 sheet metal parts, 6 lower die cavities, 7 extrusion plates, 8 grooves, 9 electric push rods, 10 spheres, 11 air pressure rods and 12 sphere grooves.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a stamping riveting die which comprises an upper die 1 and a lower die 2 and is characterized in that: go up the mould upper end and be provided with hydraulic column 3, go up 1 lower extreme of mould and install spliced pole 4, 2 middle parts of lower mould are equipped with die cavity 6 down, 6 one side of die cavity are provided with recess 8 down, recess 8 internally mounted has electric putter 9, 9 one end fixed connection stripper plates 7 of electric putter, it is equipped with sheet metal component 5 to go up between mould 1 and the lower mould 2.
Further, in the above technical solution, a sphere groove 12 is provided at the front end of the connecting column 4, two sides of the interior of the sphere groove 12 are both provided with a pneumatic rod 11, and one end of the pneumatic rod 11 is provided with a sphere 10.
This practical theory of operation:
referring to the attached drawings of the specification, when the invention is used, the sheet metal part 5 is placed above the lower die 2, the connecting column 4 is driven by the hydraulic column 3 to punch the sheet metal part 5, the electric push rod 9 drives the extrusion plate 7 to be matched with the air pressure rod 11 to extrude the two sides of the sheet metal part 5 by the tension of the ball 10, the lower part of the sheet metal part is wide and the upper part of the sheet metal part is narrow, the sheet metal part and the sheet metal part are riveted together and can not be separated, when the upper die 1 leaves, the ball 10 contracts back into the ball groove 12 under the action of the air pressure rod 11, so that the sheet metal part 5 is conveniently riveted again to be extruded, and through a stamping process, the riveting of the two sheet metal parts can be completed, the riveting firmness of the two sheet metal parts after stamping is very good, the stable fixing mode between two sheet materials or two products is realized, the production efficiency is greatly improved, and the product cost is reduced, so that the processing procedures are reduced, the production efficiency and the product quality are improved, and the production cost is reduced.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
