Abstract

The utility model relates to a punching die for a lockset bottom box, comprising an upper die and a lower die. The punching die is characterized in that the front half part of the lower die is provided with straight notches, a square groove and a die hole; the two straight notches are squared; the two straight notches are symmetrical along the central line of the lower die; the position of the square groove is located in the middle of the two straight notches and the die hole is arranged at the back end of the square groove; a molding cavity is arranged at the back half part of the lower die and a molding convex block is arranged in the molding cavity; the front edge of the molding cavity is provided with a cropping edge; the back edge of the molding cavity is provided with a positioning clamping opening; and the distance between the straight notches is equal to the width of a material plate. The die disclosed by the utility model can finish working procedures of punching a hole, punching a right-angle edge and bending and molding can be finished once; the procedures of punching the hole and molding can be carried out at the same time; the machining efficiency can be improved once; the die is reasonable in design, the production of waste materials is reduced and the cost is reduced; and the punching die is matched with an automatic feeder so that the personnel cost is reduced and the working efficiency is improved.

Description

Diel for box at the bottom of the lockset

Technical field

The utility model relates to a kind of Design of Dies, relates in particular to a kind of punch forming for box at the bottom of the lockset, realizes disposablely finishing punching, rushing right-angle side and bending and molding.

Background technology

General when being used at the bottom of the lockset box machine-shaping, because end box is originally as the box body shape, and offer porose in the bottom of end box, end box offers rectangular hole on one side, and in order to improve the hardness of box at the bottom of the lockset own, need to adopt the stamping machine bending and molding, stamping forming the time, need at twice punching press: punching and moulding, punching and moulding separate machined original, efficient is low, the waste material amount is large, and cost is high, and can only move charging by armrest in transportation processing, can not lean on the autoloader feeding, working (machining) efficiency is lower.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model provides a kind of disposable punching of finishing box at the bottom of the lockset, has rushed the mould of right-angle side, this three process of bending and molding.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of diel for box at the bottom of the lockset, comprise mold and bed die, first half position on described bed die offers straight cut, square groove and nib, this straight cut is square, quantity is two, and described two straight cut are symmetrical with the center line of bed die; The position of described square groove is in the middle of two straight cut, and described nib is opened in the rear end of square groove; Later half position on the described bed die offers forming cavity, is provided with the moulding projection in this forming cavity, is provided with the blank limit at the leading edge of forming cavity, is provided with limited bayonet in the back edge of described forming cavity.

Further, in order to guarantee position Aligning degree in Forging Process, the number of described limited bayonet is two, is separately positioned on two turnings of forming cavity.

Further, conveniently in bending, finish blank, described blank is provided with cutoff edge on the limit.

For the quick stamping straight arm of angle on flitch, the spacing of described two straight cut equals the width of flitch.

The beneficial effects of the utility model: this mould can disposablely finish box at the bottom of the lockset punching, rush right-angle side, bending and molding operation, punching, bending and molding carry out simultaneously, working (machining) efficiency doubles, the mould appropriate design, reduce the generation of waste material, reduce cost, cooperate with autoloader, reduce employee's cost, increase work efficiency.

Fig. 3 is the schematic diagram of box at the bottom of the lockset;

Fig. 4 is that another angle of box is observed schematic diagram at the bottom of the lockset.

Among the figure: 1, box at the bottom of bed die 2, nib 3, forming cavity 4, limited bayonet 5, moulding projection 6, blank limit 7, square groove 8, straight cut 9, flitch 10, the lockset.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Ask for an interview shown in Fig. 1-4, a kind of diel for box at the bottom of the lockset, this diel is used for multiple-die press, comprises mold (not shown, the position by bed die can obtain mold) and bed die 1, first half position on described bed die 1 offers straight cut 8, square groove 7 and nib 2, this straight cut 8 is square, and quantity is two, and described two straight cut 8 are symmetrical with the center line of bed die, be convenient to flitch 9 and transport with the center line of bed die, guarantee that charging is stable; The position of described square groove 7 is in the middle of two straight cut 8, the effect of this square groove 7 is slots of 10 1 sides of box at the bottom of the punching press lockset, described nib 2 is opened in the rear end of square groove, the array situation of offering of this nib 2 according to lockset at the bottom of the position in hole of box 10 bottoms decide; Later half position on the described bed die offers forming cavity 3, is provided with moulding projection 5 in this forming cavity 3, is provided with blank limit 6 at the leading edge of forming cavity 3, is provided with limited bayonet 4 in the back edge of described forming cavity 3.

Further, in order to guarantee position Aligning degree in Forging Process, and play the effect of location, the number of described limited bayonet 4 is two, is separately positioned on two turnings of forming cavity 3.

Further, be provided with cutoff edge on the described blank limit 6, the convenient operation that cuts of when plate 9 carries out bending, finishing.

For the quick stamping straight arm of angle on flitch 9, the spacing of described two straight cut 8 equals the width of flitch.

The beneficial effects of the utility model: this mould can disposablely finish box 10 at the bottom of the lockset punching, rush right-angle side, bending and molding operation, punching is plastic to be carried out simultaneously, plate 9 enters mould and carries out punching, the right angle part is carried out simultaneously on hole and the limit, enter forming cavity, positioned by two limited bayonets 4, blank limit 6 cuts off the aftershaping bending, and product follows mold to raise after the moulding, carries out the blanking working (machining) efficiency and doubles, the mould appropriate design, reduce the generation of waste material, reduce cost, cooperate with autoloader, reduce employee's cost, increase work efficiency.

It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
