Abstract
The utility model discloses one kind for multiple rivet sleeving and riveting structures in mould, including upper table surface, the lower end of upper table surface is fixed with punch fixing plate, punch fixing plate is arranged right below part fixed plate, on the fixed following table in its lower section of part fixed plate, punch fixing plate is equipped with multiple formed punches, which is characterized in that the top of each formed punch is equipped with a spring.The utility model carries out sleeving and riveting to rivet by increasing spring above original formed punch, rivet top thickness tolerance is balanced using the decrement of spring, since spring has certain compression space, and spring force is adjustable, guarantee to be that each rivet can provide the stable power that presses, phenomenon that can be unstable with the multiple rivet pressure-off power of effective solution, reduces the generation of defective products.The progressive die be can use to replace stand-alone device, realize a punching press, there is no materials to reverse, and has saved the cost of stamping of equipment investment and single-piece, while improving production efficiency.
Description
Technical field
The utility model relates to one kind for multiple rivet sleeving and riveting structures in mould, belong to auto parts and components assembly equipment technology
Field.
Background technique
Several rivets are had on some parts (for example, sliding rail) of the seat of automobile, rivet and part are by independent
Parts machining molding after installed.The thickness of general rivet upper end can have certain tolerance, some rivet upper ends
Thickness is thick, and some rivet upper ends thickness is thin.In the prior art, rivet and part are fixed together using rigid stamp, one
When secondary punching press multiple rivets, it may appear that the pressure-off power after the rivet punching press less than normal of rivet upper end is bad, the reason is that mold meeting
It is propped up by rivet upper end part bigger than normal, it is insufficient to lead to rivet force, while rigid stamp also can cause one to the flatness of part
Fixed influence, as shown in Figure 1.To solve the problems, such as this method at present be: multiple working procedure is used, is pressed one by one, according to
Actual height of rivet adjusts device height.But be that cannot achieve to produce in the progressive die in this way, single mode punching press can only be used,
Inefficiency, and have defective products generation.
Summary of the invention
Technical problem to be solved by the utility model is: providing a kind of raising production efficiency, saving equipment investment and list
Part cost of stamping is used for multiple rivet sleeving and riveting structures in mould, solves when a punching press multiple rivets, how to avoid
The bad problem of pressure-off power after the rivet punching press less than normal of rivet upper end.
In order to solve the above-mentioned technical problem, there is provided one kind for multiple rivets in mould for the technical solution of the utility model
Sleeving and riveting structure, including upper table surface, the lower end of upper table surface are fixed with punch fixing plate, and the part that is arranged right below of punch fixing plate is consolidated
Fixed board, part fixed plate are fixed on following table in its lower section, and punch fixing plate is equipped with multiple formed punches, which is characterized in that every
The top of a formed punch is equipped with a spring.
Preferably, the spring is nitrogen gas spring.
Preferably, the elastic force of the nitrogen gas spring is between 2.5t-10t.
Preferably, multiple grooves are equipped in the upper table surface, each spring is set in a groove.
Preferably, each formed punch includes protrusion and ontology, and protrusion is connect with ontology below, and protrusion is set to recessed
In slot, punch fixing plate is equipped with multiple and ontology size and number homogeneously matched hole, and raised diameter is greater than the interior of hole
Diameter.
The utility model carries out sleeving and riveting to rivet by increasing spring above original formed punch, utilizes the compression of spring
Amount is to balance rivet top thickness tolerance, and since spring has certain compression space, and spring force is adjustable, guarantee be
Each rivet can provide the stable power that presses, phenomenon that can be unstable with the multiple rivet pressure-off power of effective solution, reduce
The generation of defective products.The progressive die be can use to replace stand-alone device, realize a punching press, there is no materials to reverse, and saves
The cost of stamping of equipment investment and single-piece, while improving production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing mold；
Fig. 2 is a kind of schematic diagram for rivet sleeving and riveting structures multiple in mould.
Specific embodiment
To be clearer and more comprehensible the utility model, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
The utility model is a kind of for multiple rivet sleeving and riveting structures in mould, as shown in Figure 2 comprising upper table surface 1, on
The lower end of table top 1 is fixed with punch fixing plate 2, and punch fixing plate 2 is arranged right below part fixed plate 3, and part fixed plate 3 is solid
It is scheduled on following table 4 below, punch fixing plate 2 is equipped with multiple formed punches 5, and the top of each formed punch 5 is equipped with a spring
8.Multiple grooves are equipped in upper table surface 1, each spring 8 is set in a groove.Each formed punch 5 includes protrusion and ontology, protrusion
It is connect with ontology below, protrusion is set in groove, and punch fixing plate 2 is equipped with multiple homogeneous with the size and number of ontology
Matched hole, raised diameter are greater than the internal diameter in hole.
In the present embodiment, spring 8 is realized using nitrogen gas spring, according to the size of rivet, power that nitrogen gas spring is set as
Between 2.5t-10t (t is the meaning of ton, 1t=1000kg), rivet punching press is carried out using elastic force, may be implemented to rivet punching press
Pressure maintaining afterwards, relative to rigid contact, the flatness of part can be greatly improved.
By the utility model, after material being placed in mold, forming operation is carried out to part, it then will be molding
Part is punched out, then rivet is compressed in the hole of each part, disposable operation is realized, it is not necessary that part and rivet is independent
It is placed in another mold and is suppressed.
