Abstract

The utility model relates to a punched die for the lock hook hole of an aluminum alloy window, which comprises a male die (punching head) and a female die. The utility model is characterized in that the female die is composed of a die holder and a blade body which is fixed on the side upper part of the die holder through an arc suspension arm. The punched die has reasonable design, the stress concentration point of each part of the female die is eliminated, the cross section of the suspension arm which connects with the blade body and the die holder is enlarged, and the punching strength resistance of the whole female die is enhanced. The lock hook hole manufactured by adopting the punched die is smooth and standard. The utility model is an ideal special machining die for the lock hook hole of the aluminum alloy window.

Description

Punched die for hook hole of aluminium alloy window lock

The utility model relates to the punching out mould, especially a kind of punching out mould that is used for aluminum window snap close installation position hook lock.

At present, building all adopts the window of aluminium alloy structure basically, and what adopt when the hook lock of processing aluminium alloy structure window is a kind of punching out mould (see figure 3) of ledge structure.This punching out mould by master mold by die holder, blade bodies, and the elongated cantilever that blade bodies and die holder link together constituted, because the sectional area of elongated cantilever is less, thereby influenced the anti-punching press intensity of punching out mould master mold, fracture between master mold blade bodies and the die holder takes place easily, causes mould to damage.In addition, because the syndeton of the blade bodies of described ledge structure punching out mould master mold and die holder all is directly to intersect, the intersection does not all have slick and sly transition structure, easily causes the stress of each intersection to concentrate, and the anti-punching press intensity of punching out mould master mold is reduced.Secondly, because the unreasonable structure of ledge structure punching out mould master mold, when processing aluminum window hook lock, the distance of the lateral surface of lock-bit hole lateral border and sash is shorter, causes the snap fit of the latch hook of packing into and window frame not tight.

The purpose of this utility model is the deficiency that exists at above-mentioned aluminum window hook lock punching out mode structure, and it is good to design a kind of intensity, the aluminum window hook lock punching out mould of easy operating.

The utility model aluminum window hook lock punching out mould comprises male model (drift) and master mold, it is characterized in that: master mold is by die holder and be fixed on the blade bodies that its side top has a punching out hole by the arc cantilever and constitute, the step vertical sidewall that blade bodies and die holder constitute has an arc groove, and its shape is like a horizontal hook.

The utility model aluminum window hook lock punching out mould, reasonably designed the structure of master mold, eliminated the stress concentration point at each position of master mold body, increased the cantilever cross section that connects die holder and blade bodies dexterously, strengthened the anti-punching press intensity of master mold integral body, because the distinctive hook shape structure of this punching out mould master mold, blade bodies increases from the window material lock-bit hole amount of stretching into during actual the use, and the lateral surface that can make lock-bit hole lateral border and sash material is apart from broadening.Thereby eliminated the untight phenomenon of latch hook and snap fit.Adopting the smooth standard of hook lock of this punching out mould processing, is the special-purpose punching out mould of a kind of desirable hook lock.

The concrete structure of the utility model aluminum window hook lock punching out mould is provided in detail by the following drawings and embodiment.

Fig. 1 is the structural representation of aluminum window hook lock punching out mould;

Fig. 2 is the vertical view of punching out mould master mold shown in Figure 1;

Fig. 3 is existing ledge structure punching out mould master structure schematic diagram.

Embodiment: can be clear that from Fig. 1 and Fig. 2 aluminum window hook lock punching out mould is made up of male model (drift) (10) and master mold (9), master mold (9) constitutes by die holder (1) with by the blade bodies that arc cantilever (2) is fixed on its side top, blade bodies lateral surface (4) links to each other with arc cantilever lateral surface (5), blade bodies (3) has an arc groove (7) with the step vertical wall that die holder (9) constitutes, and the arcwall face (6) of arc groove (7) links to each other with the last plane of die holder (1).Have punching out hole (8) on blade bodies (3) and the arc cantilever (2).

Claims

1, a kind of aluminum window hook lock punching out mould, comprise male model (drift) (10) and master mold (9), it is characterized in that: master mold (9) is fixed on blade bodies (3) formation that its side top has punching out hole (8) by die holder (1) with by arc cantilever (2), blade bodies (3) has an arc groove (7) with the step vertical sidewall that die holder (1) is gone up the plane formation, and its shape is like a horizontal hook.
