Description

Blanking die with ball guide pillar structure

Technical field

This utility model relates to a kind of blanking die with ball guide pillar structure。

Background technology

Stamping-out is the process for stamping of part or the blank isolating required form and size from plate。The capital equipment adopted is blanking die。The primary structure of blanking die includes upper bolster, the upper trimming die that upper bolster bottom is arranged, die shoe, it is arranged on the lower cavity die on die shoe top and is arranged on die shoe top and is positioned at the stock guide of lower cavity die both sides, the height of stock guide is higher than lower cavity die, the bottom of upper male mould is commonly made to and the boss of blank stamping-out mating shapes, and the size of boss is basically identical with the size of die, in order to make upper bolster drive upper male mould time motion stabilization, generally also guide pillar is set in mould bases bottom, die shoe is offered pilot hole, led by guide pillar and being slidably matched of pilot hole, but above-mentioned guide frame guiding poor stability；It addition, blanking punch only drives vertical motion stamping-out by being arranged in line shaft on upper bolster, there is also kinetic stability difference, the problem that the hole error that is punched out is big。

Utility model content

This utility model is intended to provide a kind of and leads stably reliably with the blanking die of ball guide pillar structure。

The blanking die with ball guide pillar structure in this programme, including can the upper bolster of vertical motion, the middle part of upper bolster has the first via, being equipped with in first via can the line shaft of vertical motion, the bottom of line shaft is provided with blanking punch, it is provided with blanking punch in the bottom of upper bolster, the middle part of blanking punch has the second via, blanking punch is located in described second via, it is arranged right below die shoe at upper bolster, die shoe top is provided with lower cavity die, it is additionally provided with stamping-out guide post in the bottom of described upper bolster, blanking punch has the first pilot hole, stamping-out guide post is located in the first pilot hole, between blanking punch and upper bolster, spring it is provided with in the periphery of stamping-out guide post, two ball guide pillar structures it are arranged with between described upper bolster and die shoe。

The utility model has the advantage of: 1. when line shaft drives blanking punch vertical motion that blank is carried out stamping-out, cooperation due to stamping-out guide post and the first pilot hole, the motion of blanking punch is had an effect of guiding by stamping-out guide post, and is arranged on the spring between blanking punch and upper bolster and further the motion of blanking punch is played stable effect。2. during upper bolster vertical motion, owing to being symmetrical arranged two ball guide pillar structures between upper bolster and die shoe, owing to being provided with ball at traditional guide pillar structure post, not only there is good guide effect, and can reduce traditional guide pillar directly with the abrasion of guide pin bushing effect generation。

Further, it is respectively provided on two sides with one piece of stock guide at described lower cavity die, between two pieces of stock guides, forms guide passage。By arranging two pieces of stock guides, it can be ensured that the accuracy of blank feeding position。

Further, being also arranged with two side plates in the bottom of described upper bolster, be respectively provided with the side edge of square inside the bottom of biside plate, the distance between two blocks of side plates is equal with the distance between two pieces of stock guides。When blank stamping-out, the side edge of biside plate can push down blank, it is prevented that blank, at stamping-out shift, affects punching precision。

Further, described ball guide pillar structure includes being arranged on the vertical guide pin bushing of upper bolster bottom and being arranged on the vertical guide pillar on die shoe top, the diameter of described guide pin bushing is more than the diameter of described guide pillar, the top of described guide pillar wears in guide pin bushing, is provided with evenly distributed ball between described guide pillar and guide pin bushing inwall。Ball is evenly distributed, it can be ensured that ball and the uniformity of guide pillar effect, improves the stability of guiding。
