Description
Technical field
Technical field of mold is the utility model is related to, more particularly to a kind of metal plate brake forming mould.
Background technology
The important component of metal plate brake forming mould includes punch-pin, cavity plate and location-plate, during by slim metal plate brake forming,
Slim metal plate is placed on location-plate first, punching press is carried out to metal plate using punch-pin, and is molded by cavity plate, mold structure letter
It is single, but found in long-term use, its shortcoming is easily to cause metal plate to be broken in punching course, and especially slim metal plate is rushed
Pressure, its product qualified rate are low.
Utility model content
The utility model can solve the problem that existing curved mainly solving the technical problems that provide a kind of metal plate brake forming mould
Drawbacks described above existing for bent mould.
In order to solve the above technical problems, the technical scheme that the utility model uses is：A kind of metal plate is provided to bend to
Pattern has, including：Punch-pin, molding concave die, blank holder and hydraulic liftout apparatus, the lower surface of the punch-pin is convex globoidal, described
The forming surface of molding concave die is the cancave cambered surface being engaged with the convex globoidal, and the blank holder is sleeved on the punch-pin, described
Hydraulic liftout apparatus is arranged in the molding concave die, and the hydraulic liftout apparatus includes：Cylinder, piston, push rod and ejection block,
The ejection block is located at the underface of forming surface in the molding concave die.
In one preferred embodiment of the utility model, location-plate is also equipped with above the molding concave die.
In one preferred embodiment of the utility model, the upper end of the punch-pin is provided with die shank.
The beneficial effects of the utility model are：The utility model is simple in construction, and packing metal plate using blank holder is compressing shape
Brake forming under state, avoid occurring metal plate phenomenon of rupture in punching course, while be easy to the metal plate of shaping using hydraulic liftout apparatus
Golden discharging, improve processing efficiency.
Brief description of the drawings
Fig. 1 is a kind of structural representation of metal plate brake forming mould of the utility model；
The mark of each part is as follows in accompanying drawing：1st, punch-pin, 2, molding concave die, 3, blank holder, 4, hydraulic liftout apparatus, 5, fixed
Position plate, 6, die shank, 11, convex globoidal, 21, cancave cambered surface, 41, ejection block.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
Referring to Fig. 1 the utility model embodiments includes：
A kind of metal plate brake forming mould, including：Punch-pin 1, molding concave die 2, blank holder 3 and hydraulic liftout apparatus 4, it is described
The lower surface of punch-pin 1 is convex globoidal 11, and the forming surface of the molding concave die 2 is the cancave cambered surface being engaged with the convex globoidal 11
21, the blank holder 3 is sleeved on the punch-pin 1, and the hydraulic liftout apparatus 4 is arranged in the molding concave die 2, the liquid
Pressure liftout attachment 4 includes：Cylinder, piston, push rod and ejection block 41, the ejection block 41, which is located in the molding concave die 2, to be molded
The underface in face.
Wherein, the top of the molding concave die 2 is also equipped with location-plate 5, and the upper end of the punch-pin 1 is also equipped with die shank 6.
During work, metal plate is placed on the location-plate 5 of the top of cavity plate 2, punch press drives punch-pin 1 to move downward, until flanging
Circle 3 compresses metal plate, and punch-pin 1 continues to move downwardly into cavity plate 2, completes metal plate punching brake forming, and then hydraulic pressure ejects
Device 4 drives ejection block 41 to move up and the metal plate after brake forming is ejected into discharging.
The utility model provides a kind of metal plate brake forming mould, simple in construction, is being pressed using blank holder packaging metal plate
Brake forming under tight state, avoids occurring metal plate phenomenon of rupture in punching course, while is easy to be molded using hydraulic liftout apparatus
Metal plate discharging, improve processing efficiency.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
