Abstract

The utility model discloses a U-shaped plate forming die which comprises two lower die blocks, a push plate and a male die, the forming end face of the male die is matched with the shape of a formed U plate, the two lower die plates are respectively fixed at two ends of the push plate and from the U-shaped cavity of a female die together with the push plate. According to the utility model, since the U-shaped cavity is formed by the lower die blocks and the push plate, which are relatively independent, the effect of one-time forming is achieved and a uniform standard is formed so that the processing accuracy of the female die is ensured, a large die position error can be avoided and the assembly of a product is ensured; the female die of the die can be changed partially when worn or damaged, therefore the use cost can be reduced; and the U-shaped plate forming die has the characteristics of low processing difficulty and high processing efficiency.

Description

U-shaped sheet metal forming mould

Technical field

The utility model relates to a kind of machining set-up, particularly a kind of U-shaped sheet metal forming mould that is used for.

Background technology

The U-shaped plate has the effect of outbalance in vehicle assembling, be the U-shaped structure such as the wheel axillare of grass mower road wheel, to guarantee surrounding wheel shaft from excircle, it is protected, and make complete machine attractive in appearance.Simultaneously, the U-shaped plate in order to adapt to assembled condition, is connected with other parts in assembling process, need have less morpheme error, to guarantee versatility and interchangeability.In the prior art, comparatively general employing punch forming, one-time-shaped mould generally comprises die and punch, and die is whole structure, has more stable characteristics, can guarantee the service life of mould.

But because die is a sunk structure, and has determined the surface quality and the morpheme error of finished product, thereby processing needs higher precision; Die causes concentrated wear or destruction in the punch forming process, then mold integral need be changed, the waste processing cost, and the processing of monolithic devices die is comparatively difficult, and, cannot say for sure to demonstrate,prove U-shaped plate morpheme parameter and precision.

Therefore, need a kind of equipment that is used for the U-shaped sheet metal forming, can disposal molding; Have unified standard, the machining accuracy of die is guaranteed, avoid the generation of more large-scale bit error; Guarantee the product assembling, the mould die wearing and tearing occur or destroys can local replacing, practices thrift use cost; It is low to have the Mould Machining difficulty, the characteristics of high efficiency.

The utility model content

In view of this, the purpose of the utility model provides a kind of U-shaped sheet metal forming mould, can disposal molding; Have unified standard, the machining accuracy of die is guaranteed, avoid the generation of more large-scale bit error; Guarantee the product assembling, the mould die wearing and tearing occur or destroys can local replacing, practices thrift use cost; It is low to have the Mould Machining difficulty, the characteristics of high efficiency.

The U-shaped sheet metal forming mould of the utility model comprises lower module, top board and punch, and said punch moulding end face and U-shaped sheet metal forming shape are fitted shape, and lower module is two and is fixedly set in the top board two ends respectively, and two lower modules and top board form die U-shaped die cavity jointly.

Further, also comprise pedestal, said pedestal is provided with and is used to make the corresponding chimeric mounting groove of installing that embeds of lower module;

Further, lower module passes through bolted after embedding corresponding chimeric mounting groove;

Further, said top board does not have to connect and places pedestal upper surface.

The beneficial effect of the utility model is: the U-shaped sheet metal forming mould of the utility model, and adopt relatively independent lower module and top board to form the U-shaped die cavity, can disposal molding; Have unified standard, the machining accuracy of die is guaranteed, avoid the generation of more large-scale bit error; Guarantee the product assembling, the mould die wearing and tearing occur or destroys can local replacing, practices thrift use cost; It is low to have the Mould Machining difficulty, the characteristics of high efficiency.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a foundation plan;

Fig. 3 is the lower module bottom plan view.

The specific embodiment

Fig. 1 is the structural representation of the utility model; Fig. 2 is a foundation plan, and Fig. 3 is the lower module bottom plan view, and is as shown in the figure: the U-shaped sheet metal forming mould of present embodiment; Comprise lower module, top board 4 and punch; Said punch moulding end face and U-shaped sheet metal forming shape are fitted shape, and lower module is that two (lower modules 1 and lower module 5) are fixedly set in top board 4 two ends respectively, and two lower modules (lower module 1 and lower module 5) form die U-shaped die cavity jointly with top board; Right shape is meant that shape is identical, and is as shown in the figure, and punch 2 bottoms are configured ends, and outer rim is the U-shaped structure, identical with U-shaped sheet metal forming shape, said punch 2 be positioned at die die cavity top and die die cavity over against and can cooperate the shape of formation U-shaped plate with the die die cavity; During use, punch 2 makes punch 2 cooperate with die U-shaped die cavity downwards, with the punch forming of grass mower vehicle frame connecting plate; As shown in the figure, punch 2 tops are provided with punch shank 3, are convenient to cooperate with the power set installation; Make this structural integrity strong, good stability.

In the present embodiment, also comprise pedestal 6, said pedestal is provided with and is used to make the corresponding chimeric mounting groove of installing (chimeric mounting groove 6a and chimeric mounting groove 6b) that embeds of lower module (lower module 1 and lower module 5); Adopt the inserted type detachable mounting structure, can keep firm installation, and lower module is removed and installed conveniently, be convenient to Mould Machining simultaneously.

In the present embodiment, after embedding corresponding chimeric mounting groove (chimeric mounting groove 6a and chimeric mounting groove 6b), lower module (lower module 1 and lower module 5) passes through bolted; As shown in the figure, lower module (lower module 1 with lower module 5) bottom surface is provided with screwed hole (screwed hole 1a and screwed hole 5a), and bolt can pass through the bolt hole insertion of chimeric mounting groove (chimeric mounting groove 6a and chimeric mounting groove 6b) bottom land and fastening with screwed hole.

In the present embodiment, said top board 4 does not have connection and places pedestal 6 upper surfaces, need not install, and directly places to get final product, and is simple and convenient.

Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
