Description

Bending cutter die for forming plate flanging reinforcing ribs

Technical Field

The utility model relates to mechanical sheet metal processing technology field, concretely relates to be used for fashioned cutting die of bending of panel crimp strengthening rib.

Background

At present, the light weight of the automobile industry is more and more emphasized under the influence of the world energy crisis and the environmental pollution. As is well known, the weight reduction of the equipment is realized by reducing the quality of the equipment as much as possible and ensuring the manufacturing cost within a reasonable range on the premise of ensuring the strength and the safety performance, so as to realize the integration of safety and economy. In order to improve the energy density, selecting sheet plates, reducing assembly parts and improving the strength of products are great challenges to the sheet metal industry, and improving the strength of the products by adding reinforcing ribs on the products is an effective method, at present, the traditional method is realized by adopting a stamping process, and the main defects of the method are as follows: a special stamping die is needed, and the die opening is needed for the stamping die of the patent, so that the production period is greatly increased, and the production cost is increased; moreover, once the size of the workpiece needs to be changed, the whole stamping die needs to be changed, and even only scrapped, and the stamping die is manufactured again.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: the bending cutter die for forming the plate flanging reinforcing ribs can finish the forming of the reinforcing ribs during bending.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a be used for fashioned cutting die of bending of panel crimp strengthening rib includes: the cutting die comprises an upper cutting die 1 and a lower cutting die 2, wherein an extrusion groove corresponding to the reinforcing rib is formed in the cutting edge of the upper cutting die 1, and an extrusion convex hull corresponding to the extrusion groove 4 in the cutting edge of the upper cutting die 1 is formed in the lower cutting die 2.

As a preferable scheme, in the bending cutting die for forming the plate edge bending reinforcing ribs, the extrusion convex hull and the lower cutting die 2 are in an integrated structure.

As a preferable scheme, in the bending cutting die for forming the plate bending reinforcing ribs, the extrusion convex hull 8 and the lower cutting die 2 are of a split structure.

As a preferable scheme, in the bending cutting die for forming the plate edge bending reinforcing rib, a specific setting mode of the extrusion convex hull 8 is as follows: the lower cutting die 2 is provided with an insert mounting hole penetrating through the lower cutting die 2 at a position corresponding to the extrusion groove 4 at the cutting edge of the upper cutting die 1, an embedded insert 3 is arranged in the insert mounting hole, and the end part of the corresponding end of the embedded insert 3 is provided with an extrusion convex hull 8 corresponding to the extrusion groove 4.

The utility model also provides a stamping-free bending method of the plate edge bending reinforcing rib, which comprises the steps of modifying the upper and lower cutting dies of the bending cutting die, arranging an extrusion groove corresponding to the reinforcing rib at the cutting edge of the upper cutting die, and adding an extrusion convex hull corresponding to the reinforcing rib at the lower cutting die, wherein the shapes of the two are opposite; when the reformed bending cutting die is used for bending the plate, the plate is extruded by the upper cutting die and the lower cutting die to form the reinforcing rib, and the bending and the forming processing of the reinforcing rib of the plate are rapidly completed.

The utility model has the advantages that: the modified bending cutting die is adopted to bend the plate, the plate is extruded by the upper cutting die and the lower cutting die to form the reinforcing ribs, the bending and the forming processing of the reinforcing ribs of the plate are completed quickly, the production period is greatly shortened, and the die sinking cost is reduced, a stamping process is omitted, and the production cost is greatly reduced.
