Abstract
The utility model relates to a mechanism for punching the core of a punched hole which comprises a movable die, a fixed die and an opening and closing cylinder, wherein the movable die is fixed on an upper sliding chute of the fixed die through a slider so as to slide in the upper sliding chute and form a core punching die which is conveniently stretched into a pipe fitting; the movable die and the fixed die are respectively provided with a lower punched hole and an upper punched hole which are interpenetrated; corresponding surfaces of the movable die and the fixed die are arranged aslant; the shape of the cross section of the core punching die formed by the movable die and the fixed die corresponds to the shape of the cross section of the pipe fitting; the inclined surface of the movable die is inclined outwards and inwards along the central axis of the core punching die; a movable die draw bar is arranged inside the fixed die; one end of the movable die draw bar is connected with the movable die; the other end of the movable die draw bar is driven by the opening and closing cylinder to slide; the opening and closing cylinder is fixed at the back end of the fixed die by a fixed seat; and the mechanism not only can be conveniently stretched into the pipe fitting, but also can be fixed on the inner wall of the pipe fitting through expansion to rapidly punch a hole so as to prevent the punched hole of the pipe fitting from deforming, in addition, the mechanism has very useful value.
Description
Technical field
The utility model belongs to the pipe fitting punch mechanism, particularly a kind of punching punching mechanism that can prevent pipe fitting punching distortion.
Background technology
The pipe fitting punching is a common operation in the pipe fitting processing; Usually add man-hour, utilize the be fixedly clamped two ends at pipe fitting punching position of plant equipment, perhaps utilize the punching fixed bar to extend into pipe fitting punching position; Control towards the needle penetration pipe fitting with the punching cylinder again, form the punching up and down of pipe fitting.When adopting plant equipment to be fixedly clamped pipe fitting; The plant equipment of pipe fitting departs from pipe fitting punching position owing to be fixedly clamped, and edge, pipe fitting punching position deforms easily, and is bigger for the pipe fitting deformation area of rigidity material difference; When adopting punching fixed bar fixed fitting; If punching fixed bar and pipe fitting inner wall stay the gap too little, punching punching mechanism just is difficult for penetrating in the pipe, so pipe fitting punching efficient is extremely low; If punching fixed bar and pipe fitting inner wall stay the gap too big, edge, pipe fitting punching position deforms easily, and is bigger for the pipe fitting deformation area of rigidity material difference.
Summary of the invention
In order to remedy above deficiency, the utility model provides a kind of punching punching mechanism, can conveniently stretch into pipe fitting, can be fixed in pipe fitting inner wall through expansion again, and punching rapidly prevents pipe fitting punching distortion, has very useful value.
The technical scheme of the utility model is: a kind of punching punching mechanism, comprise movable mold, fixed die and folding cylinder, and it is fixing to slide between this movable mold and the fixed die; And formation is convenient to stretch into the punching mould in the pipe fitting; Corresponding respectively following punching and the last punching that is provided with mutual perforation of this movable mold and fixed die, and this movable mold and fixed die corresponding surface be tilted configuration, is provided with the movable mold pull bar in this fixed die; This movable mold pull bar one end connects this movable mold, and the other end drives slip by this folding cylinder.
Further improvement as the utility model is provided with chute in this fixed die, and this movable mold is fixed in this fixed die upper hopper chute slip through slide block.
As the further improvement of the utility model, the section configuration of this punching mould that this movable mold and fixed die are formed is corresponding with the pipe fitting section configuration, and the inclined plane of this movable mold along the central axis direction of this punching mould outward and slope inwardly.
As the further improvement of the utility model, this folding cylinder is fixed in this fixed die rear end through holder.
The useful technique effect of the utility model is: said movable mold and fixed die slide fixing, and said movable mold is tilted configuration with the fixed die corresponding surface, when movable mold and fixed die slip are staggered; This punching mould cross-sectional area of forming by this movable mold and fixed die; Than when this movable mold and fixed die reset, this punching mould cross-sectional area of being made up of this movable mold and fixed die is little, so under the dislocation state; This punching die face is long-pending little, stretches in the pipe fitting easily; And under the reset mode, this punching die face is long-pending to be increased, and is fixed in pipe fitting inner wall through the expansion of punching mould, forms the movable mold of this punching mould and following punching and the last punching that the fixed die corresponding position is respectively equipped with mutual perforation simultaneously, helps the pipe fitting punching.

The specific embodiment:
In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, below describe in detail:
A kind of punching punching mechanism comprises movable mold 2, fixed die 1 and folding cylinder 3, and this folding cylinder 3 is fixed in this fixed die 1 rear end through holder 31; Be provided with chute 12 in this fixed die 1, and this movable mold 2 is fixed in this fixed die 1 upper hopper chute 12 slips through slide block 23, and formation is convenient to stretch into the punching mould in the pipe fitting; This movable mold 2 and the corresponding respectively following punching 21 and last punching 11 that is provided with mutual perforation of fixed die 1; And this movable mold 2 is tilted configuration with fixed die 1 corresponding surface, and the section configuration of this punching mould of forming of this movable mold 2 and fixed die 1 is corresponding with the pipe fitting section configuration, and the inclined plane of this movable mold 2 along the central axis direction of this punching mould outward and slope inwardly; Design like this; When movable mold 2 relative these fixed dies 1 skidded off, this punching mould cross-sectional area of being formed diminished, and is provided with movable mold pull bar 22 in this fixed die 1; These movable mold pull bar 22 1 ends connect this movable mold 2, and the other end drives slip by this folding cylinder 3.
The operation of the utility model is like this:
1) at first start folding cylinder 3 and advance, this folding cylinder 3 slides through movable mold pull bar 22 control movable mold 2, makes this movable mold 2 stagger with fixed die 1, and this punching mould cross-sectional area after staggering like this diminishes, and helps pipe fitting and is inserted in this punching mould;
2) after pipe fitting is inserted in this punching mould, and aim at the last punching position on pipe fitting punching position and the fixed die 1, start this folding cylinder 3 and retreat; Reset with fixed die 1 up to this movable mold 2, at this moment, the cross-sectional area of this punching mould increases; Help expansion and be fixed in pipe fitting inner wall; This punching mould reset mode simultaneously, punching 11 connects with following punching 21 each other on this, is convenient to the pipe fitting punching;
3) start the punch mechanism on the pipe fitting this moment, after the pipe fitting punching finishes, start the folding cylinder and advance, take out pipe fitting again, pipe fitting punching distortion can not take place in pipe fitting processed like this, has not only improved the product quality after processing but also improved working (machining) efficiency.
Utilizing the punch mechanism process technology on the pipe fitting is not the technological innovation of the utility model, does not describe in detail at this.
