Abstract

The utility model relates to an inner side plate of semi-closed type press frames, which is a component of a body of a mechanical press and belongs to the technical field of the mechanical press. The utility model is mainly characterized in that the inner side plate is similar to a ring-shaped structure corresponding to a stress side plate of the semi-closed type press frame; the centre line of pressure is regarded as the boundary, the length of the front end is longer than that of the rear end; the inner side plate is fixed to the inner side of the stress side plate of the semi-closed type press frame; based on angle deformation reduction after stress of the semi-closed type press frame, the inner side plate regards the centre line of pressure as the boundary and the front and the rear ends of the inner side plate realize the structure approximate to equal strength so that the angle deformation can be further reduced. To a manufacturing enterprise of the mechanical press, the technical scheme can be used for improving the quality and the grade of the mechanical press; to wide users of the mechanical press, the service life of dies can be extended; the quality of stamped articles can be improved; the manufacturing cost of products can be reduced; the structure is simple.

Description

Half-closed hydropress frame interior plate

Technical field

The utility model relates to a kind of half-closed hydropress frame interior plate, is the parts in the fuselage of punching machine, belongs to the punching machine technical field.

Background technology

The fuselage of existing machinery forcing press is a frame, no matter cast, still constitute with the steel plate welding, seem from the side and be the C type, also claim open top roll housing in the industry, no matter this class frame is specified nominal pressure size, a common weakness is all arranged, promptly frame can produce angular deformation when stressed, enterprise has designed and the similar C type of the stressed side plate of open top roll housing interior plate for this reason, fixes with stressed side plate, and this C type interior plate is from the Center of Pressure line, front end depth length is much smaller than rear end depth length, the technique effect that reduces angular deformation is limited, and has increased the weight of whole machine body, and this enterprise has designed half-closed hydropress frame for this reason, its technique effect that reduces angular deformation is fairly obvious, but also exists certain angular deformation.

Summary of the invention

The purpose of this utility model is the deficiency that also exists certain angular deformation at the half-closed hydropress frame of this enterprise design, more or less also can have influence on the service life of mould to a certain extent, also can influence the situation of pressed part quality, provide further to reduce angular deformation, help improving a kind of half-closed hydropress frame interior plate of pressed part quality more.

The purpose of this utility model is achieved through the following technical solutions, a kind of half-closed hydropress frame interior plate, it is characterized in that the stressed side plate of the corresponding half-closed hydropress frame of described interior plate like structure in the form of a ring, with the boundary of Center of Pressure line, its front end length is longer than rear end length.

The utility model is for further improving the technique effect that half-closed hydropress frame reduces angular deformation, designed the interior plate of the circulus that matches with the stressed side plate of half-closed hydropress frame, be fixed on the stressed side plate of half-closed hydropress frame inboard, after half-closed hydropress frame is stressed, reduce on the basis of angular deformation, interior plate is demarcated with the Center of Pressure line, approximate equal strength structure has been realized in its front-end and back-end, thereby further reduced angular deformation, the technical program is concerning the manufacturing enterprise of punching machine, but the quality of elevating mechanism forcing press retaining, concerning the users of punching machine, more help prolonging the service life of mould, improve the quality of pressed part, reduce the manufacturing cost of product, the utility model is simple in structure, has very strong practicality, remarkable economic efficiency and social benefit.

Description of drawings

Fig. 1 is the utility model master TV structure schematic diagram;

Among the figure, 1 interior plate, 2 windows.

The specific embodiment

Further specify the utility model in conjunction with the accompanying drawings and embodiments, interior plate 1 of the present utility model is structure in the form of a ring, and corresponding pressure pusher side plate window is provided with window 2 on interior plate 1, is the boundary with the Center of Pressure line, its front end length is longer than rear end length, forms approximate equal strength structure.

Claims

1, a kind of half-closed hydropress frame interior plate is characterized in that the stressed side plate of the corresponding half-closed hydropress frame of described interior plate like structure in the form of a ring, and with the boundary of Center of Pressure line, its front end length is longer than rear end length.

2, half-closed hydropress frame interior plate according to claim 1 is characterized in that corresponding framework lateral plate window is provided with respective window on the interior plate.
