Embodiment one:
Such as Fig. 1 to Fig. 6, a kind of sliding window sash shape corner cut decompressor, including punch die 10 and drift 20.
Sliding window sash shape corner cut decompressor is for excising the corner cut 32 on 30 liang of flank limits 31 of sliding window sash horizontal aluminum alloy frame section bar.The sliding window sash horizontal aluminum alloy frame section bar of the present embodiment is a kind of bridge-cut-off aluminium alloy, is provided with " C " shape bridge cut-off 36 and main cavity 37.The wing limit of shape of peripheral frame both sides is stretched out from the side wall 33 of the main cavity of shape of peripheral frame, and the wing limit of both sides is being stretched out along to the displacement extending out a wing limit wall thickness.The corner cut on shape of peripheral frame two flank limit includes a base 34 and a side 35, and the plane of base and side is orthogonal, and base is in the side of the side wall 33 of shape of peripheral frame main cavity, and side is on the cut wing limit of corner cut and is perpendicular to the direction of extension on wing limit.
Punch die is arranged on the work top 41 of punch press.Punch die is provided with supporting surface 12 and left and right sides 13, and supporting surface is for the side wall 33 of the main cavity of supporting frame section bar, the medial surface on left and right sides difference corresponding sides frame section two flank limit.Punch die both sides should be respectively equipped with a punch die mouth 11 in the position of shape of peripheral frame two flank limit corner cut, punch die mouth from the both sides of punch die towards recessed in punch die, punch die mouth be provided with upper trimming die along 14 and side stamp die along 15, upper trimming die edge is arranged on the supporting surface side of punch die, and upper trimming die is along the base 34 corresponding to shape of peripheral frame wing limit corner cut；Side stamp die edge is arranged on the side of punch die, and side stamp die is along the side 35 corresponding to shape of peripheral frame wing limit corner cut；It is provided with punch die angle beta=15 ° between sidewall 16 and the two sides of punch die of punch die mouth；The sidewall of described punch die mouth tilts along inside punch die from described upper trimming die.
Two drifts are had to be arranged on a drift installing plate 42, drift installing plate is perpendicular to the work top of punch press and is perpendicular to the direction of extension of punch die, drift installing plate is provided with two drift motion guide blocks 43 being symmetrical in the position of punch die, two drift motion guide blocks respectively and are provided with α=15 degree, punching press angle between the direction of motion of drift main shaft, drift is provided with guide groove 23, two drifts are separately mounted on two drift installing plates, the guide groove of two drifts is respectively fitted on two drift motion guide blocks, is also respectively provided with upper guide plate 47 on two drift motion guide blocks.
Two drifts move guide block along left drift respectively by guide groove and right drift moves, and guide block moves back and forth.
Drift be provided with lower punching press along 21 and side blow pressure along 22, two drifts respectively from the left and right sides of punch die towards oblique movement in punch die mouth, the angle between the direction of motion and the punch die left and right sides of two drifts is i.e. described punching press angle α；When two drifts move to punch die mouth, the lower punching press of drift is along the upper trimming die edge corresponding to punch die, and the side blow pressure of drift is along the side stamp die edge corresponding to punch die.
The punch die angle of the punch die mouth of the present embodiment is equal with punching press angle.
Punch press main shaft 44 moves along the direction being perpendicular to work surface of punching machine, is provided with a punching press crossbeam 45 on punch press main shaft, connects two drifts in hinged way by a punching press connecting rod 46 respectively at the two ends of punching press crossbeam.
It is provided with locating piece in the front end of punch die.
When the sliding window sash shape corner cut decompressor of the present embodiment works, sliding window sash horizontal aluminum alloy frame section bar is placed on punch die；The main cavity of aluminum alloy frame section bar is placed on above punch die, the side wall of shape of peripheral frame main cavity contacts with the supporting surface of punch die, shape of peripheral frame two flank limit is corresponding with punch die left and right sides to be contacted, on the locating piece of the front end that the front end of shape of peripheral frame withstands on punch die, as shown in Figure 3.
As shown in Figure 4, move under punch press main shaft, two drifts are promoted to move to the direction of two punch die mouths respectively by punching press crossbeam and punching press connecting rod, punching press angle α is had between the direction of motion and the shape of peripheral frame two flank limit of two drifts, corner cut clout 38, respectively from the oblique incision shape of peripheral frame two flank limit, outside on shape of peripheral frame two flank limit, is excised by two drifts from two flank limits.Complete the sliding window sash horizontal aluminum alloy frame section bar after corner cut excision as shown in Figure 5.
The punching press characteristic that 15 ° of punching press angles are based on aluminium alloy extrusions wing limit determines, the too small meeting in punching press angle enables aluminum alloy to section bar wing limit and is deformed or tears, the structural volume of conference aggrandizement apparatus is crossed at punching press angle, also can increase punch press main shaft, punching press crossbeam and the active force of punching press connecting rod, reduce the ram efficiency of punch press main shaft.Therefore, under conditions of the punching press effect ensureing aluminium alloy extrusions wing limit, less punching press angle should be selected.
The sliding window sash horizontal aluminum alloy frame section bar completing corner cut excision can be connected with 90 degree of connecting methods with sliding window sash smooth rabbet or hooked rabbet.It is that sliding window sash horizontal aluminum alloy frame section bar is connected with 90 degree of connecting methods with sliding window sash smooth rabbet 50 shown in Fig. 6.
The sliding window sash shape corner cut decompressor of the present embodiment is simple, convenient, and efficiency is high.Due to two drifts respectively from the oblique incision shape of peripheral frame two flank limit, outside on shape of peripheral frame two flank limit, otch in the outside on shape of peripheral frame two flank limit is neat and smooth, overlap or burr will not be produced, make the aluminum alloy push-pull sash profile being completed smooth attractive in appearance.
