Abstract

The technology provides a punching device which can move vertically and linearly, can punch a hole with qualified quality and higher speed, and is difficult to damage. The punching device comprises a rack, a female die fixed on the rack, and an upper die plate which can move vertically relatively to the rack; a punch corresponding to the female die is fixedly arranged on the upper template, and the upper template is connected with the rack by a guide post-guide sleeve pair in an up-down sliding manner.

Description

Hole punched device

Technical field

Present technique relates to hole punched device.

Background technology

Existing hole punched device 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 hole punched device 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 hole punched device also is easy to damage simultaneously.

Summary of the invention

The purpose of present technique provides the hole punched device 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 hole punched device 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.

The beneficial effect of present technique: owing to have guide pillar guide pin bushing pair; 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; So cope match-plate pattern (and drift) had both made with the fast speeds punching; Still can guarantee punching quality, nor fragile.

In order to guarantee that further drift can move along straight line, above-mentioned hole punched device is fixed with the drift cover that moving up and down of drift is played guide effect on frame, and drift passes the drift cover.Preferably drift has two, and so just punching out simultaneously goes out two holes.

Above-mentioned hole punched device, 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 hole punched device.

Fig. 2 is the schematic perspective view of hole punched device.

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 hole punched device 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. hole punched device 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.

2. hole punched device as claimed in claim 1 is characterized in that: on frame, be fixed with the drift cover that moving up and down of drift is played guide effect, drift passes the drift cover.

3. hole punched device as claimed in claim 2 is characterized in that: drift has two.

4. hole punched device 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.
