Description
Technical Field
The utility model relates to a press die field, concretely relates to follow-up mould.
Background
The bed die of stamping die is mostly the closed angle in the existing market, and the contact of one-tenth point between machined part and the lower mould causes stress concentration easily for the machined part is at the in-process of bending, and the indentation appears easily and the condition of straining has reduced the qualification rate, has increased manufacturing cost.
Disclosure of Invention
For solving the deficiencies of the prior art, the utility model aims to provide a simple structure, convenient operation's servo-mould.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a follow-up mould, includes mould and lower mould, its characterized in that, lower mould include follow-up mould and base, be provided with the through-hole on the base, the through-hole top is provided with a plurality of recesses, the recess sets up to spherical structure, follow-up mould includes backup pad and a plurality of follow-up spheroid, follow-up spheroid is fixed to be set up in backup pad below one side, follow-up spheroid sets up in the recess.
Preferably, an opening is formed in one side, close to the center of the through hole, of the top of the groove, the length and the width of the opening are both larger than the radius of the follow-up ball body, the follow-up die can conveniently move along with the pressing of the upper die, and point contact is effectively changed into surface contact.
Preferably, the follow-up ball body and the groove are arranged in a clearance fit mode, so that a lubricant is added conveniently, and the follow-up die is prevented from being stuck.
More preferably, a clamping groove is formed in one side, away from the follow-up ball, of the supporting plate, and a reed is arranged in the clamping groove, so that the die can be automatically reset after the die is completely worked and a workpiece is taken away.
The utility model discloses an useful part lies in: the utility model discloses change into the face contact with the point contact between former stamping process lower mould and the machined part, very big improvement the atress situation of machined part, by the work piece of bending fish tail or indentation basically not appearing, effectual improvement product quality and qualification rate are applicable to the panel processing of various required precision.

The meaning of the reference symbols in the figures: 1. the device comprises an upper die, 2, a workpiece, 3, a lower die, 4, a follow-up die, 5 and a base.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
A follow-up die comprises an upper die 1 and a lower die 3.
As can be seen from fig. 3 and 4, in the conventional bending process, the workpiece 2 and the lower die 3 are in line contact at the contact point a shown in the drawing, and the pressure is concentrated on the line indicated by point a in the process of deforming the plate material, and the pressure is concentrated, and at this moment, the lower die 3 always rubs the plate material at point a, so that the indentation and the scratch caused by the friction are easily formed.
According to fig. 1 and 2, an original lower die 3 is improved, the improved lower die comprises a follow-up die 4 and a base 5, a through hole is formed in the base 5, a plurality of grooves are formed in the tops of the through holes and are of spherical structures, the follow-up die 4 comprises a supporting plate 401 and a plurality of follow-up balls 402, the follow-up balls 402 are fixedly arranged on one side below the supporting plate 401, and the follow-up balls 402 are arranged in the grooves.
One side of the top of the groove, which is close to the center of the through hole, is provided with an opening, and the length and the width of the opening are both larger than the radius of the follow-up ball 402, so that the follow-up ball 402 can move along with the pressing of the upper die, and point contact is effectively changed into surface contact.
Follow-up spheroid 402 passes through clearance fit with the recess and sets up to clearance fit and is convenient for increase emollient, prevents that the dead condition of card from appearing in the follow-up mould.
The whole follow-up die 4 can rotate around the circle center of the circle, when the workpiece is bent, the workpiece 2 and the follow-up die 4 are in a surface contact state all the time at the contact point B, the pressure intensity of the contact position is greatly reduced, and the generation of indentations is reduced.
One side, far away from the follow-up ball 402, of the supporting plate 401 is provided with a clamping groove, and a reed is arranged in the clamping groove, so that the die can be automatically reset after the die finishes working and a workpiece is taken away.
The utility model discloses an useful part lies in: the utility model discloses change into the face contact with the point contact between former stamping process lower mould and the machined part, very big improvement the atress situation of machined part, by the work piece of bending fish tail or indentation basically not appearing, effectual improvement product quality and qualification rate are applicable to the panel processing of various required precision.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
