Description
Technical field
The present invention relates to a kind of Wedge mechanism, the Wedge mechanism of a kind of band lateral pressing function.
Background technology
Automobile metal plate work is in order to meet the demand of each side such as moulding, function, and often the shape of product is the most very
Complicated.Before the complicated position, hole opened in shape is to ensure that the most again each key position of automobile is installed smoothly
Put forward condition, and the hole opened in complicated profile, itself just has particularity.Therefore, how to ensure
The precision of this some holes, is to ensure that the key of car load welding precision.
The use of wedge is a kind of conventional means of the position, complicated hole solving complicated stamping.Wedge mechanism passes through
Upper drive block, cooperation between lower drive block and slide block and angular transition, solution cannot use forward to repair and rush position
That puts repaiies the problem of punching.When cannot use forward Xiu Chong position, usual mould material pressing core can not effective binder.
So, during the trimming and piercing die of this position of mould, it is impossible to enough ensure that this position of sheet metal component is not because of deburring
Punching and produce profile change.During trimming and piercing die, the change of sheet metal component profile, directly influences between part
Overlap joint, thus affect the welding precision of car load.So, how to ensure to repair the having of position of punching by forward
Effect binder is to ensure that car load plate effectively overlaps, it is ensured that the key of car load welding precision.
Such as, the Chinese invention patent description of Application No. 201510125434.9 discloses one tiltedly
Wedge mould, it includes mould body, lower mould body, material pressing core, reverse wedge mechanism, lower mold insert and
One chute etc., the advantage of this cam die is that die size is little, this cam die as traditional moulds not
Possesses the function of lateral binder, therefore for the position of punching cannot be repaiied by forward, it is impossible to ensure to repair to rush precision.
As it is shown in figure 1, as a example by the hat rack 100 of certain vehicle, circled positions was assembled in welding and car load
Position, hole on this face and edge seam are required higher by journey, but circled positions binder during conventional ones
Core can not be good binder effect is played in this position, so during punching is repaiied in this position,
Position, hole and the border seam precision of this position be can not well ensure, car load welding and assembling affected.
The Chinese utility model patent description of Application No. 201020150800.9 discloses a kind of mould
Wedge flanging structure, specifically disclose upper bolster, lower mold drive block, wedge, flange cutter block, activity lower mold,
The parts such as fixing lower mold, material pressing core and nitrogen spring, it is mainly solved by one nitrogen spring of increase
The binder problem of forward Xiu Chong position cannot be used.But the pressure-plate-force of nitrogen spring and binder area have
Significant limitation, therefore this mould is not suitable for large-scale sheet metal component.
Summary of the invention
It is an object of the invention to provide the Wedge mechanism of a kind of band lateral pressing function, of the prior art to solve
