Description
Technical Field
The utility model relates to the field of machining, specifically be a synchronous forming die of tensile and flange shaping.
Background
In recent thirty years, with the rapid development of metallurgical industry, mechanical industry, electronic industry and the like, the upgrading and updating of fastener products and the continuous progress of the fastener industry are driven all over the world. In particular, in recent years, the form of fastener products is more complicated, and the existing five-station and six-station equipment cannot meet the requirements of the existing conventional forming process of part of novel products. In past production, a single station could only satisfy a single form of molding, for example: stretching, flange forming and shaping, and provides a synchronous forming die for stretching and flange forming.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Not enough to prior art, the utility model provides a tensile and synchronous forming die of flange shaping has solved foretell problem.
(II) technical scheme
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a synchronous forming die of tensile and flange shaping, includes the last mould and the lower mould of mutual adaptation, and one side of lower mould is provided with and is used for following ejecting pushing mechanism in the lower mould with the work piece, one side of pushing mechanism is provided with the three needle covers, one side fixed mounting that the three needle covers deviates from pushing mechanism has three needle pads.
Preferably, the lower die comprises a main film shell and a main film, the main film is provided with a die cavity, and the main film is located inside the main film shell.
Preferably, the pushing mechanism comprises a limiting ring, a spring, a push pipe and a push rod, the limiting ring is arranged inside the main film shell, the spring is arranged inside the limiting ring, the push rod and the push pipe are arranged in the middle of the spring, and the ejection end of the push pipe extends into the die cavity of the main film.
Preferably, one end of the three-pin sleeve corresponding to the punching rod is fixedly provided with a punching rod cushion block, and the punching rod cushion block is connected with the punching rod.
(III) advantageous effects
Compared with the prior art, the utility model provides a tensile and flange shaping synchronous forming die possesses following
Has the advantages that:
1. compared with the conventional production process of wheel nuts, the drawing and flange forming synchronous forming die needs at least six stations for production by a cold header, and the die set can save one station for production, thereby simplifying the process and reducing the die cost.
Drawings
FIG. 1 is a schematic view of a mold in place;
fig. 2 is a schematic view of a static mold structure.
In the figure: 1. a main membrane shell; 2. a primary film; 3. a limiting ring; 4. a spring; 5. three needle sleeves; 6. three-needle cushion; 7. pushing the tube; 8. punching a rod; 9. punching a rod cushion block; 10. and (4) an upper die.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
Referring to fig. 1-2, a synchronous forming mold for stretching and flange forming comprises an upper mold and a lower mold which are matched with each other, a pushing mechanism for ejecting a workpiece from the lower mold is arranged on one side of the lower mold, a three-needle sleeve 5 is arranged on one side of the pushing mechanism, and a three-needle pad 6 is fixedly mounted on one side of the three-needle sleeve 5, which is far away from the pushing mechanism.
Further, the lower die comprises a main film shell 1 and a main film 2, a die cavity is formed in the main film 2, and the main film 2 is located inside the main film shell 1.
Further, pushing mechanism includes spacing collar 3, spring 4, ejector sleeve 7 and dashes excellent 8, and spacing collar 3 sets up in the inside of main membrane shell 1, and the inside of spacing collar 3 is provided with spring 4, and the centre of spring 4 is provided with towards excellent 8 and ejector sleeve 7, and the ejecting end of ejector sleeve 7 extends to in the die cavity of main membrane 2.
Furthermore, a punching rod cushion block 9 is fixedly installed at one end, corresponding to the punching rod 8, of the three-needle sleeve 5, and the punching rod cushion block 9 is connected with the punching rod 8.
The working principle is as follows: in the forming process, firstly, the stretching action of the heavy lightening hole is finished, after the stretching action is finished, the main die 2 is limited by the limiting action of the limiting ring 3, and the downward action is stopped, so that the flange forming action is achieved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
