Description
Technical field
The utility model relates to the processing molds of auto parts and components, more particularly, to one kind for adding inside automobile rear longitudinal girder
Strong part mold.
Background technique
In front portion of car body primary structure, floor side member is one of most important power-absorbing.In collision process below
In, impact kinetic energy is absorbed by the plastic deformation of material, energy absorption characteristics and deformation pattern are directly determined and collided below
The malformation of body tail in journey, to touch the safety of fuel system after affecting.The design of back longitudinal beam structure is needed
It follows and successively becomes larger back to front (garage direction is back to front), to guarantee reasonably to deform order and good in collision process
Good energy-absorbing effect.Automobile longitudinal girder has significant effect body of a motor car collision performance, therefore it is required that stringer has good resist
Impact and bending resistance.
The structure of automobile rear longitudinal girder generally comprises beam body and reinforcer, and wherein reinforcer is mounted in beam body, generally
Low alloy steel plate is generallyd use when production to be stamped to form, or is repeatedly pressed and molded using mold.
Summary of the invention
The purpose of this utility model be exactly in order to overcome the problems of the above-mentioned prior art and provide it is a kind of it is high-efficient, at
This is low to be used for automobile rear longitudinal girder inner reinforcing elements mold.
The purpose of this utility model can be achieved through the following technical solutions: one kind inside automobile rear longitudinal girder for reinforcing
Part mold, including upper die and lower die and guide post, which is characterized in that set in the upper mold there are two with reinforcer shape to be formed
Match and be in the punch-pin being arranged in pairs, the lower die is equipped with the cavity plate to match with the punch-pin.
The corresponding punch-pin of station and cavity plate there are four setting on the upper die and lower die, including station a position flange, station
B separates punching, station c flange, and station d deburring shaping is equipped with the tablet line in right-angled intersection at each station.
Punch-pin a at the station a includes the sky except the two convex portion a and convex portion being arranged in pairs
White part, the tablet line in right-angled intersection are located at two protrusion centers a, and the next on longitudinally disposed tablet line
It sets and has been respectively provided with a positioning hole, and be equipped with die parting line in the edge of the convex portion a.
Punch-pin b at the station b includes two convex portion b being arranged in pairs, at four angles of convex portion b
It is respectively provided with a punching, the tablet line in right-angled intersection is located at two centers convex portion b, and in the material of right-angled intersection
Cut-off rule is equipped with by piece line, the punching periphery is reserved with waste material side.
Punch-pin c at the station c includes two convex portion c being arranged in pairs, and opposite in two convex portion c
On one side be equipped with flange line.
Punch-pin d at the station d includes two convex portion d being arranged in pairs, in the quadrangle of two convex portion d
Place is equipped with trimming line.
Compared with prior art, the utility model has the advantage that
1, original similar punching press mold technique now changes thinking based on one-piece design mold, again after process structure optimization,
By original single-piece technological design at left and right clamping system, production lathe occupation rate is saved, the difficulty of die debugging is reduced,
The stability of mold production is improved, the most important quality for improving parts product is greatly improved work efficiency and reduced
Production cost.
2, the advantages of being designed using molding, technically there is following breakthrough:
First, when being typically designed reinforcer product, one-piece design mode is generallyd use, existing improved technology scheme, using a left side
Right member merges mode and designs, and is advantageous in that forming is that the right and left is symmetrical to part in first time, enhances the intensity of mould structure, raw
Both sides lateral force offsets each other when production, substantially increases the stability of production mould.
Second, it is analyzed from product structure, in station b blanking, more stationary point waste materials are come out, neither the material benefit of influence part
With rate, and pre-punched hole can be rushed, later procedure can carry out process part processing positioning using four pre-punched holes, substantially increase in this way
The stability of mold production.
The waste material that third, such as previous process reserve more, flanging forming process can increase the pressure of part piece surface at station c
Charge level product prevents from expecting at this due to cannot keeping under control when flange, causes product sideline unstable, passes through and reserve waste material, technically solve
This kind of the occurrence of, substantially increase the stability and production mould debugging difficulty of part；In addition in subsequent processing station d
Place cuts off reserved waste material, and product entire so orderly forms on the different station of same mold, and one-pass molding can obtain
To two pieces product, high-efficient, good product quality.
