Abstract

The utility model discloses a vehicle body floor blanking die limiting device. The vehicle body floor blanking die limiting device comprises upper and lower die seats, wherein an upper template is fixedly mounted on the internal side surface of the upper die seat; a lower template is fixedly mounted on the lower die seat; a material pressing plate is fixedly mounted on the internal side surface of the upper template; guide sleeves are respectively arranged on two sides of the internal side surface of the upper template; guide columns are fixedly mounted on the two sides of the upper surface of the lower template respectively; the guide columns are embedded in the guide sleeves and slide up and down along the inner walls of the guide sleeves; a locating block is fixedly mounted on the lower template; and a spring is connected between the upper and lower templates. The vehicle body floor blanking die limiting device disclosed by the utility model has a simple structure; the original cylindrical limiting column is changed into an oblong limiting block and the limiting block is made from a material with higher hardness; therefore, the limiting block obtains greater contact area and very high hardness so that the deformation of the limiting block is avoided and the blanking quality of the product is improved.

Description

Car body floor blanking die stopping means

Technical field

The utility model relates to a kind of car body floor blanking die stopping means.

Background technology

Car body floor is controlled stroke by hydraulic press when producing; And the stroke of hydraulic press is to lean on oil pressure control, and stroke will glide when oily temperature rise, thereby causes the damage to limited post; Generally limited post be circular and contact area smaller, easy deformation.

The utility model content

The purpose of the utility model provides a kind of car body floor blanking die stopping means; Change columniform limited post into rectangular limited block; Use the higher material of hardness to process limited block; Make limited block have bigger contact area and very high hardness like this, avoid the distortion of limited block.

The technical scheme of the utility model is following:

A kind of car body floor blanking die stopping means; Include upper and lower die holder, said upper bolster medial surface is installed with cope match-plate pattern, is installed with lower bolster on the described die shoe; It is characterized in that: be installed with holding pad on the medial surface of said cope match-plate pattern; The both sides of cope match-plate pattern medial surface are respectively equipped with guide pin bushing, and the both sides of said lower bolster upper surface are installed with guide pillar respectively, and described guide pillar is nested in the guide pin bushing and slides up and down along the inwall of guide pin bushing; Be installed with locating piece on the said lower bolster, be connected with spring between the described upper and lower template.

Described car body floor blanking die stopping means, it is characterized in that: the bottom of said die shoe is installed with the pad pin.

The beneficial effect of the utility model:

The utility model is simple in structure; Change original columniform limited post into rectangular limited block, and use the higher material of hardness to process limited block, thereby make limited block have bigger contact area and very high hardness; Avoid the distortion of limited block, improved the stamping-out quality of product spare.
