Background technology
Existing metallic plate drawing and forming device generally comprises base plate, mould and elevating bracket.Mould is made up of die and top board, and top board is fixed on the elevating bracket, and die is fixed on the base plate.By the motion of elevating bracket, make sheet metal be subjected to the extruding of mould, reach the purpose of moulding., be subjected to the restriction of product stripping and moulding process, traditional drawing and forming mould need have certain gradient, to make things convenient for deviating from of product, causes the curvature of product cross section bigger.Therefore, the shape of product of traditional stretch forming process is more single, can only be for circular or oval.Bonding except needs when the product of machining shape more complicated, a lot of subsequent handlings such as freeze, also make the quality instability of product, occur peeling off, leaking phenomenons such as weldering, sand hole easily.In addition, the discontinuity of sheet material during stretching, the stress of stretching is bigger, occurs the vestige of stretching easily in the side of product, has influenced the aesthetic appearance of product and the working strength of side.
In order to address the above problem, following patented technology has been proposed in the prior art:
A kind of sheet metal forming device is disclosed as China Patent No. " 200520063729.X ", its open day is on November 08th, 2006, its technical scheme is that described sheet metal forming device comprises mould and base, mould is made up of die and top board, described top board is provided with hydraulic cylinder, is provided with a container that mucus is housed and is interconnected with hydraulic cylinder, die respectively between hydraulic cylinder and the die; Be provided with the mucus conduit between container and the die; Be provided with the valve that matches with conduit between hydraulic cylinder and the die; Be provided with lifting platform between die and the base; Lifting platform comprises stage body and crane; Die comprise at least two can be along the module of stage body planar slide.But in the actual forming process of metallic plate, owing between die and the top board trickle gap is arranged, this can make the gas pressure in the die reduce, and not only causes shaping speed slow, also will cause the sheet metal forming failure.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that the sheet metal forming device exists in the prior art, provide a kind of shaping mould for metallic plate, behind employing the utility model, to sheet metal forming the time, can prevent that the pressure in the die from reducing, and improves shaping efficiency.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of shaping mould for metallic plate comprises mould and base, and mould is made up of die and top board, and top board is provided with hydraulic cylinder, is provided with a container that mucus is housed and is interconnected with hydraulic cylinder, die respectively between hydraulic cylinder and the die; Be provided with the mucus conduit between container and the die; Be provided with the valve that matches with conduit between hydraulic cylinder and the die; Be provided with elevating mechanism between die and the base, it is characterized in that: the bottom of described top board offers groove, is provided with sealing ring in the groove, and described die inserts in the groove during to sheet metal forming, and prevents that by sealing ring the gas pressure in the die from descending.
Described groove is truncated cone-shaped, and described die is provided with the truncated cone-shaped joint pin that is complementary with groove, and die is connected with top board with groove by joint pin during to sheet metal forming.
The quantity of described groove inner seal ring is two.
Adopt advantage of the present utility model to be:
One, the utility model offers groove in the bottom of described top board, and during to sheet metal forming, die uses upwards elevating mechanism that pressing plate moves, and inserts in the groove of top board until die; Wherein, the sidewall of groove cooperates the gas pressure that can prevent well in the die to reduce with die, sealing ring in the groove then can seal up the gap of die and top board junction fully, guarantee that further the gas pressure in the die can not reduce, thereby guarantee the moulding of metallic plate, compare for the prior art of representative with China Patent No. " 200520063729.X ", the utility model can further improve the shaping speed of metallic plate, improves the Forming Quality of metallic plate.
Two, in the utility model, described groove is set to truncated cone-shaped, and described die is provided with the truncated cone-shaped joint pin that is complementary with groove, during to sheet metal forming, said structure makes the combination between die and the top board tightr, can prevent effectively that the gas pressure in the die from descending.
Three, in the utility model, the quantity of described groove inner seal ring is set to two, and dual-seal is carried out in the junction of die and top board, and sealing effectiveness is better, further improves shaping efficiency and the Forming Quality of metallic plate.
