Abstract
The invention discloses a guide structure for a blanking die. The guide structure for the blanking die is stable in guidance and comprises a vertical guide sleeve arranged at the lower portion of an upper die holder and a vertical guide column arranged at the upper portion of a lower die holder. The diameter of the guide sleeve is larger than that of the guide column. The upper portion of the guide column penetrates into the guide sleeve. An annular holding frame is arranged on the inner wall of the guide sleeve and provided with multiple balls. The balls are obliquely arranged in parallel at equal intervals.
Description
Technical field
The present invention relates to a kind of guide frame for blanking die.
Background technology
Stamping-out isolates the part of required form and size or the process for stamping of blank from plate.The capital equipment adopted is blanking die.The primary structure of blanking die comprises upper bolster, the upper trimming die that upper bolster bottom is arranged, die shoe, be arranged on the lower cavity die on die shoe top and be arranged on the stock guide that die shoe top is positioned at lower cavity die both sides, the height of stock guide is higher than lower cavity die, the bottom of upper male mould makes the boss with blank stamping-out mating shapes usually, and the size of the size of boss and die is basically identical, in order to make upper bolster drive upper male mould time motion stabilization, usually also guide pillar to be set in mould bases bottom, pilot hole offered by die shoe, led by guide pillar and being slidably matched of pilot hole, but above-mentioned guide frame guiding poor stability.
Summary of the invention
The invention is intended to provide a kind of stable guide frame for blanking die that leads.
The guide frame for blanking die in this programme, comprise the vertical guide pin bushing being arranged on upper bolster bottom and the vertical guide pillar being arranged on die shoe top, the diameter of described guide pin bushing is greater than the diameter of described guide pillar, the top of described guide pillar wears in guide pin bushing, the retainer of ring-type is provided with at the inwall of described guide pin bushing, retainer is provided with some balls, the equidistant parallel oblique arrangement of described ball.
The invention has the advantages that: compared with the guide frame of existing guide pillar guide pin bushing; by this programme guide frame for blanking die; owing to being provided with some balls between guide pin bushing and guide pillar; therefore during upper bolster drive guide pin bushing vertical motion; contacted with guide pillar with guide pin bushing by some balls; guide pillars and bushes radial force is even; guiding is stable; and avoid guide pillar and guide pin bushing directly to contact the problem of easily wearing and tearing; and due to the equidistant parallel oblique arrangement of ball; therefore increase the contact wire of ball and guide pillars and bushes, the track of ball moving is not overlapped mutually.
Further, guide pillar comprises the pillar that is arranged on die shoe top and is set in the bushing of pillar outside, bushing top can with ball contact.Guide pillar is designed to split-type structural, once work long hours, wearing and tearing be bushing, bushing easy dismounting, it is convenient to change.
Further, die shoe has up-small and down-big installing hole, be provided with nut in the aperture of installing hole, pillar is connected with described nut thread.Pillar is connected on die shoe by nut, is easy for installation and removal.
Further, be provided with spacing ring in the macropore of installing hole, bushing bottom is with tapering, and the endoporus of spacing ring has internal taper, and bushing bottom is embedded in spacing ring.Spacing ring plays the more stable effect of connection to bushing, in addition, due to pillar be arranged on die shoe by nut, therefore, when pulling down nut and pillar, bushing and spacing ring is also just for convenience detach.
Further, the limited block of level is provided with in described bushing outside.Limited block can limit the descending maximum travel position of upper bolster.
