Abstract

The utility model provides a punching machine with a plunger chip which can linearly move up and down, can punch a qualified hole by a faster punching speed and is not easy to damage. The punching machine comprises a rack, a concave mould fixed on the rack and an upper template which can move up and down relative to the rack, wherein the upper template is fixedly provided with the plunger chip corresponding to the concave mould; the upper template is connected with the rack through a guide column guide sleeve pair in a manner of sliding up and down; and the rack is fixedly provided with a plunger chip sleeve which has the effect of guiding the plunger chip to move up and down and the plunger chip passes through the plunger chip sleeve.

Description

A kind of perforating press

Technical field

Present technique relates to perforating press.

Background technology

Existing perforating press comprises frame, is fixed on die on the frame, with respect to the cope match-plate pattern that frame moves up and down, on cope match-plate pattern, be fixed with and the corresponding drift of said die, cope match-plate pattern with drive its oil cylinder that moves up and down or cylinder and link to each other.Under the drive of oil cylinder or cylinder, cope match-plate pattern drives drift and moves up and down with respect to die, thereby on the work piece between drift and the die, is going out the hole that needs.The problem of this perforating press is: because cope match-plate pattern and drift only move under driving at piston rod; The guider that does not have other; The axis that departs from piston rod when causing cope match-plate pattern and drift to move up and down sometimes; Thereby be difficult to guarantee the quality of punching, also reduced punching speed, this perforating press also is easy to damage simultaneously.

Summary of the invention

The purpose of present technique provides the perforating press that a kind of drift can straight line moves up and down, and it can go out up-to-standard hole with the punching out of punching speed faster, and not fragile.

This perforating press comprises frame, is fixed on die on the frame, with respect to the cope match-plate pattern that frame moves up and down, and on cope match-plate pattern, is fixed with and the corresponding drift of said die, and cope match-plate pattern slides up and down with frame through guide pillar guide pin bushing pair and links to each other; On frame, be fixed with the drift cover that moving up and down of drift is played guide effect, drift passes the drift cover.

The beneficial effect of present technique: because it is secondary to have a guide pillar guide pin bushing, cope match-plate pattern (and drift) can move (and not can off-straight) along straight line under the secondary guide effect of guide pillar guide pin bushing when moving up and down; The drift cover plays guide effect to moving up and down of drift, guarantees that further drift can move along straight line.So cope match-plate pattern (and drift) had both made with the fast speeds punching, still can guarantee punching quality, nor fragile.

Above-mentioned perforating press, preferably drift has two, and so just punching out simultaneously goes out two holes.

Above-mentioned perforating press, cope match-plate pattern links to each other with its oil cylinder that moves up and down of drive or cylinder.

Description of drawings

Fig. 1 is the schematic perspective view of perforating press.

Fig. 2 is the schematic perspective view of perforating press.

Among the figure, die 1, frame 2, guide pin bushing 3, drift cover 4, cope match-plate pattern 5, guide pillar 7, drift 8.

The specific embodiment

Combine accompanying drawing that present technique is done further to describe through embodiment below.

Like Fig. 1, the perforating press shown in 2, two dies 1, two 4 and four guide pin bushings 3 of drift cover all are fixed on the frame 2.Cope match-plate pattern 5 upper ends link to each other with the piston rod that drives its oil cylinder that moves up and down or cylinder.Cope match-plate pattern 5 bottoms be connected with four guide pillars 7 of stretching in the guide pin bushing with pass the drift cover with corresponding two drifts 8 of said die.Guide pillar 7 forms with guide pin bushing 3 and slides up and down pair; Drift 8 forms with drift cover 4 and slides up and down pair.

Claims

1. perforating press comprises frame, is fixed on die on the frame, with respect to the cope match-plate pattern that frame moves up and down, and on cope match-plate pattern, is fixed with and the corresponding drift of said die, and it is characterized in that: cope match-plate pattern slides up and down with frame through guide pillar guide pin bushing pair and links to each other; On frame, be fixed with the drift cover that moving up and down of drift is played guide effect, drift passes the drift cover.

2. perforating press as claimed in claim 1 is characterized in that: drift has two.

3. perforating press as claimed in claim 1 is characterized in that: cope match-plate pattern links to each other with its oil cylinder that moves up and down of drive or cylinder.
