Description

A kind of aluminium alloy extrusions shearing die

(1) technical field:

The utility model relates to the aluminium alloy extrusions processing technique field, is a kind of shearing die of aluminium alloy extrusions specifically.

(2) background technology:

Along with growth in the living standard, people more and more pay attention to the health of living environment and beautify, and aluminum alloy doors and windows are extensively adopted by people because of the advantage of himself.At present; the processing technology of aluminum alloy doors and windows generally adopts manual line; after sawing straight blanking with portable cutting stock; transfer sawing to cut about carrying out again; aluminium is cut the face of easy harm people; and easily hinder finger during cutting; also need correction of the flank shape after having cut; owing to adopt manual operations easily to cause fixed bit inaccurate, make the angle of shearing bigger deviation occur, thereby percent defective is improved; cutting technique all is to cut processing in addition; thereby cause the waste of aluminium alloy extrusions, and production efficiency is low, can not forms large-scale production.

(3) summary of the invention:

Problems such as the purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of shearing die of time saving and energy saving aluminium alloy extrusions is provided, and the shearing processing technology efficient that has mainly solved existing aluminium alloy extrusions is low, error big, waste raw material.

To achieve these goals, the utility model is achieved in that a kind of aluminium alloy extrusions shearing die, it comprises cope match-plate pattern 5, lower bolster 8, guide pin bushing 6, guide pillar 7, establish tringle 4 on the cope match-plate pattern 5, punch 2 is fixed on the cope match-plate pattern 5 by fixed head 1, and die 3 directly is fixed on the lower bolster 8, its special character is to establish pan feeding passage 9 on the described die 3, simultaneously establish sheared edge 10 at the top of die 3, sheared edge 10 is triangle, and punch 2 is complementary with sheared edge 10.

For the further above-mentioned purpose that realizes, a kind of aluminium alloy extrusions shearing die of the present utility model, its described sheared edge 10 is " bifurcation " type, also can be two triangles; The cut part bit strip of its described punch 2 bottoms has angle; Described pan feeding passage 9 is located in the die 3, can be two, establishes the butt joint inclined-plane in the both sides of the correspondence of die 3 respectively and shears charging aperture, discharging opening and face directly and shear charging aperture, discharging opening, and pan feeding passage 9 communicates with shearing charging aperture and discharging opening; On die (3), establish material-dropping hole.

Compared with the prior art a kind of aluminium alloy extrusions shearing die described in the utility model has following advantage: 1, work efficiency height, improve nearly 10 times than the work efficiency of existing shearing processing technology; 2, because sheared edge adopts " bifurcation " type, thereby make offal become fritter to fall, recyclable usefulness again, joint medicine raw material from material-dropping hole; 3, do not need secondary process, once shear machine-shaping; 4, be a kind of ELEMENTARY INTRODUCTION TO NON technology; 5, shearing processing is accurate, guarantees product quality.

(5) specific embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe a kind of aluminium alloy extrusions shearing die of the utility model in detail.

Embodiment 1, referring to Fig. 1,3,6, cope match-plate pattern 5 is made in machined, lower bolster 8, guide pin bushing 6 and guide pillar 7, fixed installation tringle 4 on cope match-plate pattern 5, be processed into die 3, offer in the two sides of the correspondence of die 3 and to shear charging aperture and discharging opening, the shape of its shape and aluminium alloy extrusions matches, the interface channel of shearing charging aperture and discharging opening is a pan feeding passage 9, is convenient to section bar and enters from shearing charging aperture, comes out from discharging opening, pan feeding passage 9 is in die 3 inside, pan feeding passage 9 can be two, can shear two section bars simultaneously, offers sheared edge 10 at the top of die 3 simultaneously, pan feeding passage 9 in sheared edge 10 and the die 3 communicates, sheared edge 10 is " bifurcation " type, offers material-dropping hole on die 3, and die 3 directly is fixed on the lower bolster 8; The punch 2 that processing and sheared edge 10 are complementary, the cut part bit strip of punch 2 bottoms has angle, punch 2 is fixed on the cope match-plate pattern 5 mounting guide sleeve 6 and guide pillar 7 between cope match-plate pattern 5, lower bolster 8 by fixed head 1.

Embodiment 2, and referring to Fig. 1,2, with embodiment 1, difference is that sheared edge 10 is triangle, and pan feeding passage 9 is one, can only shear two inclined-planes of a butt joint.

Embodiment 3, and referring to Fig. 1,4, with embodiment 1, difference is that sheared edge 10 is two relative triangles, and pan feeding passage 9 is two, can shear four inclined-planes of two butt joints simultaneously.

Embodiment 4, and referring to Fig. 1,5, with embodiment 1, difference is that sheared edge 10 is two triangles in the same way, and pan feeding passage 9 is two, can shear four inclined-planes of two butt joints simultaneously.

When a kind of aluminium alloy extrusions shearing die described in the utility model uses, an aluminium alloy extrusions can be sheared, also two can be sheared simultaneously.When shearing two inclined-planes of corner's butt joint if desired, can be with the shearing charging aperture pan feeding of aluminium alloy extrusions from the correspondence of triangle sheared edge, after having measured size on the auxiliary scale, shear, shearing by sheared edge, two inclined-planes of turning butt joint once can be cut into, middle offal is recyclable to be used again; Cut into when facing directly if desired, with the shearing pan feeding import department pan feeding of aluminium alloy extrusions from the linear pattern mouth correspondence of " bifurcation " type sheared edge, after having measured size on the auxiliary scale, shear, shearing by sheared edge, section bar can be cut into two simultaneously and face directly, middle offal is recyclable to be used again; When two inclined-planes need not only cutting the turning butt joint but also cut when facing directly, can be simultaneously shear the pan feeding import and enter two aluminium alloy extrusions from two of " bifurcation " type sheared edge correspondence, shear, cut into two inclined-planes of turning butt joint and two simultaneously and face directly; Also can shear four inclined-planes of two corner's butt joints simultaneously,, shear, can cut into four inclined-planes of two turning butt joints simultaneously the charging aperture pan feeding of section bar from two leg-of-mutton sheared edges.
