Abstract

The utility model relates to a forming die of a folded plate of an oil tank of a large-sized/middle-sized transformer, which belongs to the technical field of a pressing die of a bending machine. In order to solve the problems of high manufacturing cost and easy generation of cracks in a convex die of a compression die of a traditional bending machine, the utility model provides a bending die of a reinforcing rib of a large-sized plate material, which comprises an upper die holder and a lower die holder, wherein a convex die, an edge-pressing die holder and a joint of a pressing plate are arranged on the upper die holder; the joint of the pressing plate is installed above the upper die holder and is installed on a pressing plate of a hydraulic edging machine; the convex die comprises an upper supporting plate and an upper rolling shaft, wherein the upper rolling shaft is installed in a gap of the upper supporting plate; the edge-pressing die holder comprises a supporting plate and an edge-pressing rolling shaft; and the lower die holder is installed on a base, a concave die is installed above the lower die holder and comprises a lower supporting plate and a lower rolling shaft, and the lower rolling shaft is installed in a gap of the lower supporting plate. The convex die with the structure has low manufacturing cost and is not easy to generate cracks.

Description

Big-and-middle-sized oil tank of transformer flap shaping mould

Technical field

The utility model belongs to bender compression molding techniques field, particularly a kind of big-and-middle-sized oil tank of transformer flap shaping mould.

Background technology

The punch of existing bender press-moulding die adopts the integral design manufacturing, the manufacturing cost height, and also tensioning member corner stress is concentrated, is easy to generate the crack.

The utility model content

For the punch that solves existing bender press-moulding die adopts the integral design manufacturing, the manufacturing cost height, and also tensioning member corner stress is concentrated, is easy to generate problem of cracks, and the utility model provides a kind of large-sized sheet material ribs bender, and its embodiment is as follows:

Big-and-middle-sized oil tank of transformer flap shaping mould is installed between the pressing plate and base of hydraulic flange press, comprises upper bolster and die shoe, and punch, flanging die holder and pressing plate joint are installed on the upper bolster; The pressing plate joint is installed in the top center of upper bolster, and the pressing plate joint is installed on the pressing plate of hydraulic flange press; Punch is made up of upper bearing plate and last roller bearing, and last roller bearing has three, is installed in the breach on upper bearing plate top; The flanging die holder is positioned at the both sides of punch, is made up of gripper shoe and the flanging roller bearing that is installed on the gripper shoe; Die shoe is installed on the base of hydraulic flange press, and die is installed above die shoe, and die is made up of lower support plate and following roller bearing, and following roller bearing is installed in the breach of lower supporting plate.

As preferred version of the present utility model, along last roller bearing, down roller bearing and flanging roller bearing axially, the quantity of upper bearing plate, lower support plate and gripper shoe is no less than two; Be positioned on upper bearing plate, lower support plate and the gripper shoe on the termination, two ends baffle plate is installed.

The punch structure of this structure is simple, low cost of manufacture, and when stretching in punch inserts die, last roller bearing is done rolling friction, traditional sliding friction of comparing, and product crooked position stress is little, is not easy to produce the crack.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

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

Fig. 2 is a left-hand cutaway view of the present utility model.

The specific embodiment

Embodiment one: as depicted in figs. 1 and 2, a kind of big-and-middle-sized oil tank of transformer flap shaping mould is installed between the pressing plate 4 and base 9 of hydraulic flange press, comprises upper bolster 1 and die shoe 11, and punch 2, flanging die holder 14 and pressing plate joint 5 are installed on the upper bolster 1; Pressing plate joint 5 is installed in the top center of upper bolster 1, and pressing plate joint 5 is installed on the pressing plate 4 of hydraulic flange press; Punch 2 is made up of upper bearing plate 6 and last roller bearing 8, and last roller bearing 8 has three, is installed in the breach on upper bearing plate 6 tops; Flanging die holder 14 is positioned at the both sides of punch 2, is made up of gripper shoe 15 and the flanging roller bearing 13 that is installed on the gripper shoe; Die shoe 13 is installed on the base 9 of hydraulic flange press, and die 12 is installed above die shoe 13, and die 12 is made up of lower support plate 10 and following roller bearing 7, and following roller bearing 7 is installed in the breach of lower supporting plate;

Along last roller bearing 8, down roller bearing 7 and flanging roller bearing 13 axially, the quantity of upper bearing plate 6, lower support plate 10 and gripper shoe 15 has ten; Be positioned on upper bearing plate 6, lower support plate 10 and the gripper shoe 15 on the termination, two ends baffle plate 3 is installed.
