Description

Wedge mechanism with lateral pressing function

Technical field

The present invention relates to a kind of Wedge mechanism, particularly a kind of Wedge mechanism with lateral pressing function.

Background technology

Automobile metal plate work is in order to meet the needs of each side such as moulding, function, and often the shape of product is all extremely complex. The complicated hole position opened in shape is often to ensure the precondition that each key position of automobile is smoothly installed again, and in complexity The hole opened on type face, itself just has particularity.Therefore, how to ensure the precision of this some holes, be to ensure vehicle welding essence The key of degree.

The use of wedge is a kind of conventional means for the complicated hole position for solving complicated stamping.Wedge mechanism passes through upper driving Cooperation and angular transition between block, lower drive block and sliding block, solve that the problem of punching can not be repaiied using positive Xiu Chong positions.Can not Usual mould material pressing core can not effective binder during using positive Xiu Chong positions.So, in the trimming and piercing die of the mould position During, it is impossible to ensure the not generation type face change because of trimming and piercing die of the sheet metal component position.Metal plate during trimming and piercing die Part type face changes, and the overlap joint between part is directly influenced, so as to influence the welding precision of vehicle.So how to ensure can not Effective binder that forward direction repaiies the position of punching is to ensure that vehicle plate effectively overlaps, and ensures the key of vehicle welding precision.

For example, a kind of cam die is disclosed in the Chinese invention patent specification of Application No. 201510125434.9, It includes upper mold body, lower mould body, material pressing core, reverse wedge mechanism, lower mould insert and first chute etc., the cam die Advantage is that die size is small, and the cam die does not possess the function of lateral binder as traditional moulds, therefore for can not Forward direction repaiies the position of punching, can not ensure to repair to rush precision.

As shown in figure 1, by taking the hat rack 100 of certain vehicle as an example, circled positions are in welding and vehicle assembling process to this Hole position and edge seam on face require higher, but circled positions pair that material pressing core can not be well during conventional ones Binder effect is played in the position, so during carrying out repairing punching to the position, it is impossible to ensure the hole position of the position well And border seam precision, influence vehicle welding and assembling.

A kind of die wedge is disclosed in the Chinese utility model patent specification of Application No. 201020150800.9 to turn over Side structure, specifically disclose upper bolster, lower mould drive block, wedge, flange cutter block, the lower mould of activity, fixed lower mould, material pressing core and nitrogen The parts such as gas spring, it mainly solves the binder of positive Xiu Chong positions can not be used to ask by increasing a nitrogen spring Topic.But the pressure-plate-force of nitrogen spring and binder area have significant limitation, therefore the mould is not suitable for large-scale metal plate Golden part.

The content of the invention

It is an object of the invention to provide a kind of Wedge mechanism with lateral pressing function, to solve deficiency of the prior art, It can effectively solve the problem that can not positive Xiu Chong positions binder problem, prevent sheet metal component because of trimming and piercing die and generation type face change, So as to improve vehicle welding and assembly precision.

The invention provides a kind of Wedge mechanism with lateral pressing function, including upper bolster, wedge body and die shoe, institute The bottom for stating upper bolster is provided with nitrogen spring, safety hook and breaker bolt through after the via on the upper bolster with it is described Wedge body is fixedly connected, and the wedge body is provided with material pressing core, rushes upper die and deburring cutter block, the material pressing core and installation Guide pillar on the wedge body is slidably matched, and the top of the die shoe is provided with drive block and lower mould, the drive block with The wedge body is slidably matched, and the lower mould rushes upper die and the deburring cutter block is engaged with described.
